Abstract

The handrest support has separate support pads for the left and right hands, that for the right hand displaced along a sliding guide, with its sliding surface divided into a number of individual sliding surfaces for providing a required movement characteristic.The right hand support pad may have a number of additional functions, to provide zero power compensation for both the longitudinal and tilting movement, conversion of the displacement into incremental steps and follow up movement of the tilting of the hand. The pad may be divided into sections lying to the front and rear of the wrist, to relieve hand resting pressure and convert the resting pressure into kinetic energy.

Description

The present invention relates to a Hand support or support device for users of Keyboards, especially electronic keyboards (e.g. for computers, data entry and typewriters and Telephones).

As shown below, the invention relates to both wrist and arm supports; further also the applicability for use for general Needlework.

According to the prior art, support devices for Arm rests and wrist rests known which the Movement of the pad over the writing area of the keyboard enable.

Use appropriate devices for the all-round movement of the support linear or rotating Mechanics, e.g. E.g .: DE 40 25 143 and DE 42 30 935. DE 40 25 143 uses one over the entire keyboard Rail guide movable in both coordinate directions Support device for the wrist rest and as another alternative, using one to both Telescopic linkage mounted on the sides of the keyboard. DE 42 30 935 only uses a linear rail guide parallel to the Keyboard front, which is essential for typing necessary movement in the direction of the keyboard, or away from the keyboard, a swivel arm is used, without which the device cannot do.

The stand have mechanics corresponding to technology the following disadvantages:

You need for motion control a fitting guide, low-friction precision bearings, (for coordinate slides or telescopic rods or Swivel lever), such as. B. also ball joints and Rail guides. The prevailing through this structure Frictional forces prevent the support device from Follow hand movements without resistance while typing can; the usual structure also includes such Motion guides with a large moment of inertia disruptive effect on hand movements.

Task The present invention is the elimination of this  Disadvantages, with a motion control without fittings, d. H. without ball joints, without sliding shafts, without sliding bearings and without sliding bushes and particularly low mass moment of inertia. The low moment of inertia of the motion control the pillow remains even when using large-volume pillows received, preferably with the use of an air cushion.

In an optional design variant is such an air cushion with all-round freedom of movement through flexible or twistable support attachment according to G 93 15 862.9 from 03.02.94 according to the principle a cushion that is rocking on a rocking line (e.g. air or water pillow made of foil bags), but with Training measures according to the invention for more intensive Training of the seesaw roller, which is determined by dimensioning the Pillow filling medium results in a rolling movement of the pillow with corresponding deformation of its shell (e.g. the Foil bag) supported. The invention Training measures concern the generation of Resilience of the pillow, especially the contact surface for the hand (for hand support) or for the arm (for arm support), which is made up of two power generation components is: a) the inflation pressure of the Filling medium (e.g. air or water with air) and b) the clamping force generated by a stenter, the Pillow has a low inflation pressure, which at Hand or armrest against the frame (or pillowcase) the pillow tense.

As described in later Described embodiments are the frame preferably formed by the pillowcase itself; With four cover pages, one with a fleece Form covered window and on this by Velcro are fixed. Of course there is also Possibility of the frame in whole or in part (e.g. Angle support) made of resilient solid material to manufacture.

Below is also an embodiment described, in which the framework support of the Pillow the sloping superscript of a pillow underside affected by a ledge, making for the bearing surface of the pillow an insert between this bar and the rocker line fixation of the pillow is formed, which  supports the formation of a seesaw roller.

In a special embodiment, a trough ( 83 ) is formed by the total effect when the cushion is produced on the hand or arm support, in particular if the longitudinal fold (or longitudinal seam) of the film bag is also used as a support surface for the hand or arm. as described below ( Fig. 61 and Fig. 61 ... ).

Overview of the inventive measures for Solution of the technical problem and inventive Further training arrangements

The inventive Coping with the task does not only concern the Improvement of the movement control of the support device, but in inventive further training design additionally the solution of the technical problem, the To significantly reduce the hand rest pressure of the pillow and the breakdown of forces for those on hand on all sides pressure forces to improve significantly.

In order to improve the movement control of the support device and in particular to significantly reduce the moment of inertia while avoiding weighty bearing parts (e.g. in connection with air cushions) and universal movement of the rail-guided part, a ruler surface designed as a sliding surface is provided, on which surface-separated (small ) Glide sliding surfaces, which are directly attached to the underside of the cushion on another support surface of the cushion (hereinafter referred to as sled plate), one or more sliders being taut or guided in a correspondingly loose play by a guide line running in the longitudinal direction of the ruler, or are. Variants are described below in which the guide line running in the longitudinal direction of the ruler is designed either as a guide slot or as an outstanding guide web, and runs along the longitudinal center line of the ruler, wherein a protruding edge side of the ruler can also be included in the movement of the cushion as a guide web. The sliding surface of the ruler can also have any shape to match the shape of the keyboard, including curvatures in multidimensional directions (parallel to the keyboard front line or concave or convex to the keyboard front line); in a further option, a variant for the rotatable cushion pad is provided, in which the z. B. formed with elastic band zero position of the angle of rotation adjusts itself over the displacement of the cushion according to a predetermined function (see. Fig. 38).

There are two for motion control Basic variants are provided, one of which is the contact surface of the pillow (or underside of the pillow) in several lines by means of parallel guide lines (guide slot, Guide bridge) and a second variant, where the contact surface of the cushion (or underside of the cushion) is single-line with only one guideline. The one-line version is preferred just a sliding element as a guide element from the Guideline guided (e.g. designed as a pen), which is due to its agility on the leader line (e.g. as a pin sliding along the guide groove) at the same time forms the axis of rotation and the other sliding elements only one sliding on the sliding surface Support the cushion surface. The Guide element has a trigger protection, for. B. in Shape of a sliding plate, which is below the sliding surface slides enclosed in a guide groove, or e.g. B. between two parallel guide webs slides that have a protruding upper edge, which prevents the plate from being pulled off. In the Multi-line version, however, are measures to Twisting of the pillow on a sled plate provided, especially using elastic Tapes.

For reducing hand rest pressure and Improve the breakdown of forces at hand All-round pressure forces are provided for each hand several pillows in a row are provided, which by the compared to the state of the Technology improved movement control of the pillows in practical application is favored.

examples for Training options of the invention are: it is one Sensor technology used, which is extremely cost-effective and with which the control of the cursor (cursor) and the image functions (scrolling the pages), or also  any mouse functions made very advantageous can be.

Below are two for this sensor system described different design variants that can also be combined well and by the first of which is dependent on the generation of control signals the way the pillow is placed on the hand is pressed, makes, and another variant, at the one selected using the keyboard key Function assignment (e.g. image key or vertical cursor or cursor-horizontal) directional incremental steps are generated, which during the shift a pillow (e.g. right pillow) over the rail are generated by length scanning of the displacement path. In this connection is in a further developed variant made use of an activation signal, which about the first variant of the control signal generation is generated for a detection which indicates whether the pillow is pressed by the applied hand: d. H. Hand is on or not. In a simplified version is the activation signal immediately by a Actuation button in the effective range of the pillow lies, triggered and switched back as well or by Detection of a timeout switched back after activation.

The activation signal fulfills the purpose of the sensor electronics to indicate whether the key press of a key relates to the function assignment for the pillow input function or whether the key has only been actuated during a program function of the computer. More details are in the later part of the description explains (see. Also Fig. 28 and Fig. 29).

Other preferential measures, as follows Part of the description are explained in detail a version in which the hand rest cushion inside of a game can be moved relative to the motion control are, this shift sensed and for a motor-driven tracking control of the cushion movement in this way  is used that the pillow by means of zero force compensation follow the hand movements smoothly. For this variant can also directly scan the length of the displacement path via the drive path of the motor-driven overrun control be recorded (e.g. by uncoiled cable length using Tachometer generator, optical disc or damping measurement on a coil spring or measuring the by the coiled cable length on the insulated reel prevailing inductance, with one tap e.g. B. on the metal axis of the winding reel and another Tapped off by the metallic pressure roller of the unwound Cable).

For a variant where this is not done, the length scan of the displacement path is preferred measured by capacitive length scale.

Further details on the length measuring system are described for the figures in the following part (cf. FIG. 49) of the description.

Further preferred details relate to the manufacture of the Pillow:

For the air cushion design, it is preferred that as an air cushion, an inflated gas-tight bag Foil is used, e.g. B. from a material like them the food industry uses for vacuum bags (COLAMIN PA / PE tubular film, etc.).

In particular The air cushion is an additional training option with water or another liquid Cold storage filled, which enables it to be hot Meet the pillows in the cool box or in the fridge pre-cool.

For this variant is an option in Air cushion inserted a horizontal partition that a separate chamber for the liquid and a chamber forms for the air, causing sloshing of the liquid is avoided in the pillow.

In a preferred embodiment the foil bags on the one hand due to wider holding seams (using a heat band) welded together and further On the outside, a separating seam for each stop seam (using Heat wire) provided the one hand an absolutely creates a gastight connection and at the same time that Separates foil material.

FIG. 8 shows a variant in which the user can configure 2 options: a first one in which the underside of the cushion is placed directly on the mushroom band strip 32 d of the seesaw line on the support surface 100 ; or a second, in which the fleece underside of the pillow is placed on the mushroom band strips of the contact surface 100 via an interposed elastic band 38 , which is coated on the underside at its ends with short filaments 32 dx, the center of the elastic band remaining freely stretchable (see angle ωβ) and is also coated on the top with a mushroom band surface on which the underside of the cushion is placed. In a further option, the mushroom band strip of the seesaw line is not continuous, but is only designed as short adhesive surface pieces, one of which is provided in the middle for immediate placement of the underside of the pillow, and two on the side edges for placement of the elastic band.

A further option can be selected for this variant, for expanding the rocking area in an oblique direction, in which a shaped body (e.g. a strip with a square surface 207 ) is placed underneath and under the point where the cushion is placed on the elastic band is attached with Velcro fastener; 207 . . . is a sliding surface of the molded body with which it can move as smoothly as possible on its non-tacked side. The upper figure in Fig. 8 shows the option with the elastic band attached, the lower figure the version without the band.

In addition to the possibility of attaching the individual sliding elements directly to the underside of the cushion, this is provided for further developed exemplary embodiments on the underside of a slide plate 100 as a support surface for the cushion, the movement of the cushion along the keyboard via the individual sliding elements on the sliding surface and the cushion movement towards the keyboard front, by the rocking movement of the cushion and / or further sliding movement.

FIG. 9 shows a further variant in which, in contrast to FIG. 8, the elastic band 38 is placed crosswise on the Velcro strip 32 d of the rocking line of the mushroom band placed on the support surface 100 . Furthermore, an optional increase possibility is provided at the point of adhesion on the underside of the cushion, which is, however, carried out with an air foil cushion (cylinder 207 ). Fig. 9 shows first of all the covering of the mushroom tape strip applied to the cushion support surface, then the elastic band placed on it as a transverse strip 38 and further the twistability of the elastic band in the middle of the band ωβ.

V in FIG. 8 means the direction of movement of the slide plate 100 along the keyboard front.

If the underside of the pillow has a relatively large area of fleece material, it is provided that the areas of mushroom tapes which are not intended to adhere to the fleece band are covered directly with fleece band strips (cf. 32 Z in FIG. 9).

Fig. 10 illustrates two further embodiments of the twistable elastic and flexible mounting of the cushion side on the supporting surface 3 and 100 respectively. In the example shown above, rubber bands 38 are stretched across the support plate 3 transversely to the longitudinal direction, on which the mushroom band surfaces for attaching the underside of the fleece band cushion are attached 32 b. In the example shown below, the cushion is placed on a cross belt.

FIG. 11 through FIG. 15 illustrate embodiments for optional design variants of the air cushion, in particular for the shaping, whereby for this preferred variant of a simple pad is manufactured without the concatenated multiple chambers.

Fig. 11 shows how a molding jig 19 is inserted as a frame into the foil bag 10 prior to inflation, said forming jig different shapes can support the inflated cushion. The upper illustration shows a plan view with two outlines of the inserted mold templates (e.g. cardboard) shown in dashed lines, in the lower part there is a representation of the side view, in which the mold template is only inserted, and in the lower illustration, the mold template one side of the foil bag is additionally glued in places or over the entire underside, which gives the air cushion a flatter or flat contact surface after inflation.

Fig. 12 shows a proposal in which the air cushion has a stabilizing frame outside 19 or inside.

FIG. 13 illustrates a proposal to inflate the airbag, see. also identical positions in FIG. 11. Starting from a roll with a film tube, the rectangular piece shown in FIG. 13 is cut off from the tube on the broad side ( 55 ... folded long sides of the tube) and the first wide side is welded closed with a separating seam by means of a hot wire and separated at the same time; Furthermore, another holding seam 20 for welding the relevant film sides is placed at this point directly next to this seam with a heat band.

The piece of film cut from the roll is (by 30 ) slightly longer than the air cushion when inflated. Taking this extension 30 into account, the holding seam 24 is first welded to the heat strip, but this holding seam still leaves a narrow channel 23 on one edge side to the interior of the welded-on foil cushion. In a next step, another holding seam 21 is welded with the hot band approximately perpendicular to the last weld seam 24 , which is set in such a way that it crosses this seam 24 at the point where the narrow channel 23 is kept free, so that it can pass through it Seam 21 results in an injection nozzle for the cushion 28, 55, 24, 55 , into which an injection nozzle 22 for filling (or inflating) can be inserted. After inflation, immediately next to the holding seam 24 , which has the blowing-in channel 23 , a further holding seam is welded on the inside 27 and / or outside 26 , which closes the blowing-in channel 23 . Then the protruding part of the pillow, which was only needed for the air inlet, is separated by a separating seam using a hot wire. As a further option, a holding seam 20 can also be welded on the inside along the folded bag sides 55 with a heat band.

As a further alternative, in the version shown in FIG. 13, the film bag is also inserted a welded-in separating film or a smaller bag to form a further layered chamber which is filled with a liquid for storing cold. Other options are to use 2 foils of unequal thickness or 2 particularly thin foils instead of the bag, which are interposed with foil strips for reinforcement at the points of the welding and separating seams.

FIG. 14 illustrates a further variant for the air-film cushion, in which the film sides are welded to one another in places or points by short broad-band dash seams 63 in order to keep the cushion narrower.

Fig. 15 relates to a variant with bevelled corners pad 204 (pushed by the inflating the foil bag supplied welded, corresp lower figure of Fig. 15..); see. also FIGS. 13 and 14 for further reference designations.

An option is shown at the bottom left, how, if necessary, the cushions with Velcro can be adjusted by means of cross-stitched Velcro / fleece connection. Rocking line 40 b of the cushion adheres to 40 a of the support surface; ditto, the rail guide can be attached to a shelf of the keyboard with Velcro, or it can be fixed directly on a common support surface 9 , or it can also be set up loosely in front of the keyboard without the use of a further support surface 9 ; 34 . . . symbolizes a coil that is provided under the pillow on the pillow support, or when using a rail guide, on the bottom of the rail guide (or also on the sled plate, see later) and that is provided by a piece of metal (e.g. sheet metal foil) in the air cushion eddy current losses generated samples for the purpose of locating the deformation of the pillow case by the applied hand, as described below to Fig. 48 and Fig. 54 in detail.

Fig. 29 illustrates a further embodiment using the control of cursor and image functions by the cushion movement already explained at the beginning, optionally using a sensor coil 34 for generating the activation signal and using the length measuring system to determine the displacement path of the cushion, e.g. B. right pillow. Computer mouse 43 and keyboard terminal are looped over the flanged to the right end side of the rail guide housing 41 or 96 out of the port terminals of the microprocessor, which performs the switching function; where: 42 . . . Computer connection of the keyboard and 44 computer connection of the mouse. Switching the input functions. As already explained above, the keyboard and mouse are carried out via the activation signal, the computer keyboard and the mouse performing their functions directly when the activation signal is switched off, while the cursor control or mouse signal generation takes place via the pillows when the activation signal is switched on. As an option, e.g. For example, a mode that can be configured via software or switch position can be provided, which optionally controls only the cursor functions, or only the mouse functions, or both via the pillow input.

In addition to the variety of control options the following control is particularly preferred:

When the computer is switched on (application of the supply voltage to the electronics housed in the housing 41 of the rail guide), the software of the microprocessor starts with a status which assumes that the hand is not resting on the left pillow, which can optionally be used to calibrate the evaluation. The same applies to the electronic scale that operates on the same sensor principle in the later part of the description, which controls the adjustment of the hand support pressure by level control of an additional armrest (implemented by another rear cushion).

Furthermore, any change in the detector signal in coil 34 is evaluated as to whether the hand is pressing or lifting the cushion. A time is started for each take-off with the query whether or not a function control key on the keyboard has been pressed within the time, whereby the reverse trigger sequence can also be queried as a pre-trigger function, whether within a certain time immediately after pressing the key Time the hand was on the pillow or not to avoid overlaps in the evaluation.

If this is the case, then switches the electronics for pillow input, depending on pressed key (e.g. "X / Y" key for coordinate positioning or "<<" keys for image key function) corresponding modes are executed, e.g. B. Control of X-Y coordinate movement using the mouse function, being a pillow shift of the right Pillow, with the left hand alternately the X / Y buttons be operated and corresponding to the displacement Incremental pulses are generated, which is that of the pillow correspond to the route and follow the sign to the X movement or Y movement of the image control function for Simulate key presses or mouse signals.

To activate the activation signal it is sufficient that the hand in question (e.g. left hand) is lifted off immediately before the button is pressed, with the hand on the button after pressing the button Cushions can be placed and the activation signal remains on until a shutdown condition of the Activation signal is recognized.

In contrast, was not Button or any button other than that provided Function control buttons pressed, then remain original Mouse function and cursor input function received.

If the intended function control keys continue to be pressed when the activation signal is switched off, ie if the hand was placed on the cushion when the key was pressed, the key code is used normally by passing it on to the program via the looped microprocessor circuitry of the keyboard connector. In Fig. 29 continues to mean: 98 a, b, c, d). . . Supporting elements or sliding elements of the slide for the longitudinal movement of the rail guide.

Fig. 30 illustrates the already previously treated exemplary embodiment having provided on the underside of a carriage plate fixed slide members, and a rail guide, in which only a slide groove 106 is in sliding a single slide member 98 slidably and rotatably and at the same time forms the pivot of the carriage one hundredth The carriage is supported by further sliding elements (e.g. runners 101 ) on the rail surface (ruler surface of 99 ) which, as shown in FIG. 30c, can be designed identically to the sliding element of the pivot point 98 , but rails are not guided directly.

The angle of rotation is limited by strip 102 attached to the long side of the sliding surface. As, Fig. 30a, the rail PVC strips 99 30b two using plastic ruler strips can be adjacent to a injection molding version also from separate materials (wood profile 103 with attached strip guide 103) and placed to be produced, as opposed to Fig. 99 with under specified steel plate, or entirely injection-molded plastic design, or laminated cardboard 103 underneath, the edge sides of the cardboard being covered by the laterally raised wooden strips 102 ; from the top view only the PVC rail strips ( 99 ... made from one piece or optionally with wooden strips underneath (cross hatched), see dashed horizontal lines in the profile according to Fig. 30b) and the wood is visible, the one with Paper + plastic film-coated cardboard underside is still printed with information.

The lateral frame 102 , which in the longitudinal direction of the rail guide also forms the stop for the support elements 101 when the slide 100 is rotated, holds the end fitting pieces, which are laterally removable in the guide grooves X (on the front, for example, also made of wood, cf. 39) in Fig. 29 as described later with FIG. 71a, Fig. 71b and Fig. 71c in more detail, wherein the sliding surface (ruler) (for. example, wooden strips) on all sides by the framing is enclosed and on the wide side insertion slots for the insertion of the sliding elements of the slide plates (with the end pieces removed).

As shown in Fig. 30a illustrates to Fig. 30c, the sled base 100 is guided guide sliding element 98 given by the surface of the Gleitlineals 99 F, the height of the rails so by appropriate setting of the distance that the guide slide is guided only in the longitudinal direction and does not rest on its upper and lower plate surfaces, ie does not provide any support. Since the underside of the supporting further sliding elements 101 only have a sliding and no guiding function, the friction is reduced to a minimum.

However, if the preferred length measurement system using a rail guided slider is used for capacitive length sensing, then the height of the guided guide slider is selected so that the upper or lower slide plate of the slider is on the surface (top or bottom) of the rail during sliding is tight, which is reinforced by spring force if necessary (see. Fig. 50).

Also mean: 132 + 32 . . . Velcro underside of the pillow 1 on a mushroom ribbon.

Regarding FIG. 31: if necessary, the exemplary embodiment illustrated in FIG. 30 can be modified such that a second sliding element ( 98 A and 98 B) slides in the guide groove, whereby the slide is secured against rotation on the one hand and has minimal friction on the other hand. Furthermore, a further proposal for closing the guide groove by means of plug 107 is shown (in addition to the insertion of fitting pieces, cf. 39 in FIG. 29).

FIG. 32 illustrates an exemplary embodiment in which the coordinate guidance takes place via cross slides, that is to say that a further cross-guided slide is present for the slide guidance of the first slide. Furthermore, a parallel rail guide (tangentially parallel) of two guide grooves is provided for the exemplary embodiment according to FIG. 32. It is evident that the variants described for Fig. 30 and Fig. 31 can also be combined as a cross slide with, where z. B. the lower slide is guided as a longitudinal slide parallel to the keyboard against rotation and the upper slide is guided towards the keyboard and allows immediate rotatability.

The slide guide of FIG. 32 is identical to the previously described embodiments, except that it is performed by guided in parallel guide grooves in which the guided slider at the same time support the slide plate, ie, slide with the bottom of their upper slide disc to the rail surface, z. B. is advantageous for the variant with a preferred length measuring system. As an alternative, however, sliders could also be provided for separate non-rail-guided support of the slide plate, cf. Fig. 30c.

This means: 100 slide plate, which corresponds to the contact surface of the cushion and is guided over the further rail guide 99 B, which is also the slide for the first (lower) rail guide 99 A. 99 A is guided or set up parallel to the keyboard front.

It is evident that the slide guides described from Fig. 30 can also be used independently of any subject of the invention for a pillow for a hand rest for any other applications, in particular with the length measuring system described below and a power supply control signal rail, which is also particularly claimed as a reliable, inexpensive solution . For such other applications, the accuracy improvement of the rail guide is interesting, which is why those sliding elements that provide an anti-twist device for the slide plate by means of slide groove guides are braced against each other by spring force (e.g., as example in Fig. 32, top left, cushion shown in front view), by a plate spring 200 , under which the sliding elements are glued and which is attached with its top to the underside of the carriage.

Fig. 33 illustrates a profile section for the variant in which the slide plate can be rotated directly on the rail guide, with profile ( 103 , wood) according to Fig. 34, 99 PVC strips.

Fig. 35 illustrates a profile section for the variant in which the slide plate is guided against rotation, with profile ( 103 , wood) according to Fig. 36, 99 PVC strips.

FIG. 37 illustrates the optional rotation control β of the cushion on the path of the slide guide (in mid-M); KBS. . . Keyboard side, OPS. . . Operator side.

Fig. 38 relates to a variant in which the angle of rotation adjusts itself over the displacement path of the cushion in accordance with the curve shape of the rail guides or the width of the guide groove, in that the axis of rotation of the rotatable cushion support is carried out by a guide made along the center line of the rail guide via a rotary lever is led. This rotary lever has sliders which are supported on the inner edges of the guide at both ends of the lever, the rotation of the rotary lever being caused by changing the distance between the inner edges of the guide (ie slot width). The rail guide corresponds to Fig. 37, the middle groove being kept so wide that the sliding elements (opposite each other) slide on one of the two groove edges to both groove edges and depending on the groove width ( 67, 68, 67 ) depending on the groove width Adjust an axle 82 mounted lever 77 . The axis rotates the pillow cover.

Fig. 39 shows the axis 82 of the pillow support, which is used with press disks on a film 81, the underside of which is used as a sliding surface, to rotate the pillow.

Fig. 40 illustrates a variant in which the rail guide is installed lowered in front of the keyboard in a trough, as z. B. can be used on pull-out keyboard pads. The rail guide is preferably accommodated in the trough in such a way that the cushion height is matched to the keyboard height and can be covered by a flat cover, which instead of the hand cushion cushion cover forms the usual cover cover ( 8 c with dashed lines) and covers the hand cushion cover.

FIG. 41 illustrates a variant in which metal strips, which are contacted via contact connections K1 to K4 and are placed on the rail guide, perform a capacitive length coding, cf. also Fig. 49 and Fig. 50.

FIG. 45 shows a proposal for the detection of the angle of rotation by means of spools of the cable pull from FIG. 44, wherein the radial rotation of the cable roll pulls up a spiral spring, at the ends of which the inductance is measured as a measure of the rotation, e.g. B. according to the resonance principle via oscillator circuit (OSZ) or as a damping variable, in which case the coil spring is damped by a metal disc (disc, FIG. 45) placed in parallel thereto and the damping changes due to the changing effective coil size. 52, 53 . . .

Fig. 46, the cable drives for variant is shown by Fig. 44.

FIG. 47 shows the fastening of the cable pulls associated with FIG. 46 to the slide.

Fig. 48 illustrates the preferred principle for the detection of a signal indicative of the rocking motion of the pillow or the deformation of the pillow. Depending on the requirement criteria, it may be sufficient to attach a sheet metal foil 33 only to the inside of the air cushion on the floor 33 . For alternative evaluations, a sheet metal strip is attached to the inside on the top ( 33 B). B. is bent downwards (e.g. also for measuring the contact pressure). For both variants, an air coil is placed underneath the pillow support or under the rail guide at the point where the input option is provided by the pillow in question (e.g. far left, see generation of the activation signal above), e.g. B. in a flat cavity of the underside of the rail guide support (see also 34 in Fig. 32). If the pillow in question is above the air coil, it is exposed to eddy current damping by the piece of sheet metal glued into the pillow. B. noticeable in a damping of the resonance oscillator amplitude. The evaluation takes place, for example, in such a way that the signal of the damped parallel circuit oscillator is fed to a voltage-dependent oscillator (VCO), the frequency of which is fed into a microprocessor via averaging, or also by prior rectification at the input of the VCO, the change values for the respective change in damping of the coil forms, these change values indicate on the one hand whether the hand placed on the pillow is rocking back and forth, that is, typing, on the other hand the sign direction of the respective change or maximum scanning indicates whether the hand is lifted from the pillow. If so, then a mono time starts within the tested st whether a corresponding keyboard signal is present at the microprocessor (µP) (no longer shown in FIG. 48). If several sensors are required, the use of parallel resonance oscillators for the supply circuit of the sensor coils proves to be very advantageous because of the direct filtering effect for different measuring frequencies of the coils. 35 also means supply inductance, ditto capacitance, which is contained in the resonant circuit inductance of the coil connections 34, 36 and the parallel resonant circuit capacitance. The described adaptation of the attenuation measurement to the input of a microprocessor by means of VCO can also be used for the voltage divider measurement for FIG. 51 described below, in addition to the further circuit suggestions for capacitive scale measurement.

Fig. 49 and Fig. 50 explain the principle and exemplary embodiments for the preferred length measuring system according to the principle that metal strips (e.g. sheet metal strips) run on both sides of the slider guide (e.g. the guide groove) and the metal strips through one on the electrode surface applied in the slider guide is capacitively bridged, whereby the capacitance measured between the metal strips is a measure of the movement of the slider along the slider guide (capacitance between electrode connections K1 and K2).

In Fig. 49 top left a piece of the rail guide 99 is placed with slide films, or very thin PVC strips (which are drawn transparently in Fig. 49), the sheet metal strips 69 A, 69 B among the PVC strips Have fraying made on the inside edge of the guide slot in a sawtooth pattern. The sawtooth pattern enables the direction-dependent evaluation for the derivation of the incremental pulse corresponding to a sawtooth by means of edge differentiation. The increase distinguishes the direction of movement, the periodic sequence of spontaneous increase in capacity and slower decrease corresponding to the direction towards the trailing edge of the sawtooth, and the sequence of spontaneous decrease in capacity and slow increase corresponding to the direction towards the flatter rise of the sawtooth.

These fraying or surface recesses of the sheet metal strip are bridged by the sliding element 98 sliding in the guide slot, the underside of the upper sliding plate on the one hand pressing against the sliding surfaces of the PVC strips, and on the other hand also having a metal electrode on the underside, which has the guide slot or the sliding groove bridged.

Fig. 50 shows such a slide member (shown upside down) with a Senkrille 73 on the underside of the upper Gleittellers in which this metal electrode is embedded as a narrow strip. This version is well suited if the sliding element slides non-rotatably in the guide groove of the rail guide, e.g. B. if a parallel guide with two guide grooves is provided, cf. see left figure below in Fig. 49. However, if the guided sliding element also forms the axis of rotation, then instead of a strip, a circular electrode is embedded in the sliding element ( 98 a in Fig. 50, shown in broken lines); Furthermore, it is provided for this version that the guided sliding element is mounted on the underside of the carriage 100 via a spring (leaf spring 400 ), which ensures that the contacting of the sliding element is pressed against the sliding surface of the rail guide, depending on the spring direction this as Pressure force can be made, or also as a tensile force, if the capacitive contact instead of the upper plate 98 a is arranged on the lower plate 98 c, ie on the anti-pull-off device of the sliding plate (also on the inside) (option), the contact plates 69 A, 69 B ) are then under the PCV strips of the sliding pad of the other gliders. This version has the advantage that the sliding surface can be kept thicker on the top. The principle for the scanning of the capacitive scale can be seen from the figure at the bottom right in Fig. 49.

Furthermore, FIG. 49 shows a top view of the coding plates with a frontal front view and an enlarged view of the frontal view with the sliding element inserted.

The contacting of the sheets 69 A, 69 B is made with the contacts K1, K2 on the face of the rail where the housing for the evaluation electronics 41 is flanged.

Fig. 51 shows the equivalent circuit diagram to explain the measuring principle:

Cp is the capacity as it is without the Bridging electrode of the slider between the rails  prevails. Cgl is the additional capacity through that Bridging by means of the slider electrode, the Capacity Cgl depending on the bridged effective Cross section of the electrode plates varies, corresponding to the Sawtooth shape.

To each sawtooth flank is then over evaluating microprocessor circuit for controlling the Mouse or button functions an incremental pulse generated, with intermediate interpolations and definition of Number per length driven still generated by software can be, evaluating the slope of the Sawtooth coding of the scale (e.g. also overlay, or fraying of the sloping flank by others Sawtooth corrugation).

As shown in Fig. 51, the rail capacitance is connected with a series capacitance Ck to a capacitive voltage divider, the tap of which corresponds to the capacitance curve of the length scale (e.g. fed to a microprocessor via VCO, voltage-frequency converter converter, see above). In addition to the possibility of using the sinusoidal voltage of a parallel resonance circuit as a supply voltage, the measuring capacity can be measured as an option using a compensated voltage divider (R1, R2) with the measuring capacitance as part of its compensating capacitance, with the deformation of the rectangular supply signal, with monostable time windows through the rectangular flank of the Feed signal are triggered; Blanking signals (at coincidence gate MC1 ... MC3) blank out a window comparator signal which corresponds to the comparison of the right-angle signal and the signal tapped at the voltage divider (adapted by level converter A, VCC).

If exceeded corresponding test times (t1... t3 of the monostable Stages), at the coincidence gate is via MC1. . . MC3 on Microprocessor inputs according to quantized signal given capacity value.

Fig. 52 shows the microprocessor circuit on the left with further signal connections P1, P2, P2 for integration into the functions explained and on the right an alternative for generating the activation signal for switching to the pillow input function: instead of detecting whether the hand rest has been made on the pillow, it is on the front side The rail is provided with an end stop contact, which presses against a contact spring and switches on the activation signal as long as the contact spring is pressed by pushing it with the cushion, it means: 107 contact springs each, 98 x sliding elements with electrically connected stop contacts to the contact springs, which means that the contact springs Fastening ends of the contact springs connected contact connection conductive when the carriage hits the springs, otherwise broken.

Fig. 53 shows a variant in which the rail guide has a cavity 104 on the underside for accommodating the described sensor coil ( 34 , option) or an alternative spring plate 106 , which bends slightly when pressed by the hand rest on the cushion and on an air coil located underneath makes a damping variation for the purpose of generating the activation signal for the pillow input function.

Fig. 54 shows a variant in which, in a pillow coordinates according to four sheet metal foil strips are attached, each having four underlying air coils a Wirbelstrombedämpfung so that coordinates according to pressures at the pad surface of a coordinate contemporary Signaldedektierung permitted or coordinate proper displacements of the pad can be scanned (see later part of the description). Instead of the attenuation scan z. For example, direct vectorial pressure sensing by means of semiconductor sensors can also be carried out in order to obtain a coordinate variable in accordance with the direction, in particular also the tracking control of zero force compensation for the cushion movement.

Fig. 55 shows the corresponding circuit for this ( Fig. 54), each with an LC parallel resonance oscillator of different frequency for the damping measurement, further with optional connection of bus signal rails to the microprocessor. B. would be possible to accommodate the oscillator circuit with the coils directly on the slide plate, or to provide electrical drives on the slide plate together with control signals. In Fig. 55, three signal tapping rails are provided: for the power supply, the two rails VCC and GND, as well as a serial BUS signal rail to be used bidirectionally. Alternatively, the bus signal rail can be modulated into the current signal rail, e.g. B. by frequency coding or modulo-2 coding of a data signal, from which the supply voltage is then recovered by rectification and the time windows for the bidirectional connection of serial data streams (according to a protocol) are bridged by a capacitor on the supply voltage (see also later part the description).

FIG. 56a, FIG 56b and c show proposals for the signal supply to the preferred carriage.:

In Fig. 56a, the rail guide has three parallel guide slots, of which the two outer ones are used for guiding the carriage and for signal guidance and the middle one only for signal guidance. The signal is routed via the contact sheet strips BUS, GND, VCC inserted in the guide groove on the bottom, the tapping of which takes place in each case via a contact spring sliding thereon in the guide groove according to FIG. 56c or, in a further alternative, via a ball ( Fig. 56b) looped on a short metal chain; in Fig. 56c, b, mean: 64 + 100 printed circuit board placed on slide plate; the circuit board contains all self-sufficient components of the slide, e.g. B. inductors (see. Fig. 54 with 1 C ... outline of the pillow case) or drives.

Of course, when using the cross slide version, the contact rails of the uppermost slide can be looped through to the lower rail, whereby the slide can be used in any position using the contact pick-up spring ( Fig. 5c) and, if necessary, by attaching the sliding elements which support the slide on it Make undersize, tension on the slide guide on springs (see leaf spring above) and thus an astonishing precision can be achieved for little effort.

Fig. 57 illustrates an exemplary embodiment of the high points of the keyboard, in particular if the keyboard no Aufstelltisch, z. Is provided as according to Fig. 40. The upper illustration shows how mushroom tape strips 40 b are glued to the keyboard underside along the front front line on both sides of the keyboard. B In this aligned in the longitudinal direction of the keyboard mushroom tape strip 40 loop tapes are attached 40 c and along one of the keyboard back facing fold line d folded 40 so that after folding back the fleece side for the further setting up a Velcro connection on the mushroom tape 40 b rests, 74 b, 62 , and is used for another Velcro connection on a block to raise the keyboard. By grading different block heights, which are layered with fleece tape / Velcro strip connections, different heights of the keyboard can be set, in particular if the individual height elements e.g. B. each doubled as a multiple of 2, so they are binary graded. The back of the keyboard is also raised by such blocks. As a further alternative, a hinged row of feet of different adjustment heights is provided on the underside of the keyboard.

Fig. 58 above illustrates the placement of a cover plate over the existing Velcro connection of the support surfaces of the cushions, the cover plate 300 instead of the cushions being placed in the respective edge position limited by the stop (far out) of the slide on the Velcro connection, so that the slidability of the plate is fixed.

Fig. 58 below illustrates that the rail guide can also be bent in adaptation to modern keyboard shapes (pillows 1 and K2).

Fig. 59 illustrates the design of the air cushion as a hand cuff with a hook-and-loop fastener 199 A, which cuff can be used not only independently, but in particular also in connection with the cushions for hand support.

Fig. 60 shows an example of a power supply and powered on as described Steuersignalversorgschienen autonomous drive the rail guide, the (durchschleift of unterster rail according supreme carriage) also for 2 tracks as a cross slide can be made.

Here, a motor 500 is provided on the support plate, the roller via a belt drive 600 , z. B. rubber roller 700 drives, which slides on the rail guide (through window 800 ). As an alternative or supplement to the rubber roller, however, a toothed wheel can also engage in a toothed rack corrugation of the plastic rail surface, which runs next to the sliding surface of the slider. B. can also be produced by hot stamping.

So you get a rail guide that doesn't only suitable for the purpose of moving the pillow, but also for independent applications.

Another Execution is, for the cross slide the mobility despite blocked mechanical drive, by manual shift via regulated overrun control:

For this purpose, another cross slide, which has a low displacement play (VSP) and can be manufactured in a preferred rail guide, on the top slide plate of the first cross slide attached, or the displacement of the first cross slide immediately with a displacement game (VSP) Provide slide guide, the displacement play sensed and for motor readjustment the displacement of the first cross slide is. As a sensor z. B. simple spiral springs Preload the sled in a middle layer of VSP, and their Be measured inductance. If the sled is in a Coordinate direction moved by hand, what by Detection of the change in inductance accordingly Centering springs is determined, then it is readjusted, until the centering springs return to their value, the corresponds to their rest position (in the middle position). Variants for the sensor are still below described.

Another variant is to bring the drive wheel of the feed into a latching lifting position by lever 900 , with spring 1000 , in order to make the feed optionally also movable by hand.

The preferred rail guide can be used in any position, if necessary the sliding elements are braced against one another or against their supporting surfaces by spring force (cf. leaf springs 400 in FIG. 50 or 200 in FIG. 32). A preferred application is to use the cross slide guide in connection with an image processing system which composes the individual image sections from the image information, whereby this can be done not only for image scanning, but also for expanding the travel path of precision machines, for example if the very precise travel path of the precision machine is correlated by taking over its exact measured value via the image content of the image scan.

Subsequently, still further variants are based on the figures to Fig. 23 to Fig. 25x and Fig. Described 61 to Fig. 61x which relate primarily to the preferential variant to better support the Wippwalze, wherein the hand directly or at least in the area nearer is placed on a longitudinal fold (or on a longitudinal seam) of the tubular film cushion.

., Variants of Figure 23 to Figure 25e relate to an optional tensioning of the pad for regulating the air pressure, which is suitable both for horizontal as well as vertical position of the pad:

In Fig. 23, the cushion shows in an oblique view from below, with the trough 83 of the pad lengthwise side (with underlying longitudinal fold of the slightly inflated film tube) which is used for the hand pad or wrist pad or armrest. Another application would be hand support for handicrafts.

The tensioning device consists of a pressure plate 93 with a flanged clamping screw 84 , which, like a standardized clamping clamp, can be moved or rotated at the screw end by means of a ball-and-socket connection and presses against a flat side of the cushion, the support of the plate being supported by a thin plate 3 (e.g. B. made of plastic), in the middle of which the screw is inserted in a thread, the plate adhering to the cushion (z. B. on a fleece window 123 ) and is arranged above the pressure plate, optionally stabilized with a U-shaped or angled Holding device ( 85 ... Made of plastic or bent sheet metal) into which the cushion is inserted and the screw is inserted into a window 86 (with a longitudinal slot 88 ) which ensures that the cushion can be rocked in the direction of the keyboard and thus ensures the mobility of the clamping screw , so that the knob 84 protrudes and the holding device, for example, also via fleuschba underside of the strip is attached to the Velcro strip connection (mushroom strip strip 32 b) of the support plate 100 ;

In a further option, the pressure plate 93 is displaceably embedded in plate 3 , the pressure plate 93 being centered in a further development of the pressure plate by means of centering (ring or individual Velcro tape blocks 93 PZ), which adheres to a fleece surface of the cushion. In this variant, the plate 3 does not adhere directly to the pillow via fleece windows, but rather via a tension band which is attached to the plate on the narrow sides by means of Velcro and is looped over the air cushion within the cover; the pressure of the pillow is therefore also via the belt, cf. to Fig. 25c and Fig. 25d.

Fig. 24e shows the pressure plate 93 in detail, consisting of two discs 93 A and 93 B glued together with a flat countersink 93 f and GH and in the flat countersink hole cap 89 b, to which the threaded rod 89 secured with counter nuts 89 b and 89 a presses to rotate within the pressure plate.

FIG. 24d shows an embodiment with spacer adjustment GS for better adaptation cushion with KLTA. . . Velcro tape adhesion of plate 3 , cf. also Fig. 24c.

A further development variant is to provide a deflection (angled gear deflection or transmission 84 AT Fig. 25c), with an optional option to provide a motor drive instead of the manual drive of the tensioning screw; an alternative for the deflection is to use a guided, inclined wedge surface.

The differences from FIGS. 24a and 24b relate to the mounting of the threaded rod 89 in the holding device (in FIG. 24a in elongated hole 86 , in FIG. 24b in thread 86 ).

FIG. 25e shows an oblique view, FIG. 25d details.

In order to support the rocking behavior generated by twisting the hand rest of the pillow, the fleece side ( 132 in FIG. 21d) is preferably used as the top of the pillow.

The pillowcase is made of fabric, e.g. B. from particularly thin felt-cellulose fabric, and covered with another felt. The thin fabric cover adheres with its folded-over side parts ( 1 a, 1 b, 1 c, 1 d) directly to the fleece cover 132 , the further thick fabric cover adhering to the outside of the folded-over side parts. Liability is achieved by means of Velcro, whereby for the sake of simplicity of manufacture, preferably fluffy material (e.g. velor) is used for both sides of the fabric (e.g. ironing on) and is taped together with Velcro strips coated on both sides (e.g. by self-adhesive) double strips glued together).

Another variant, in which the pillow case is made entirely of fleece material, is shown in Fig. 70a, with a rocking line (Velcro tape C adheres to slide plate 100 ), and a hand rest attached with Velcro tape (b), whereby another fabric cover with Velcro tape is attached via this fleece material can be.

For the purpose of adjusting the distance (VHSL) with regard to the keyboard front line, the Velcro strips 40 a are guided crosswise in relation to the rocking line aligned parallel to the keyboard front and bar (HSL) (cf. also in Fig. 72b: HSL-KLT...

Fig. 61b shows a further variant with an air cushion film (LKBL, packaging material) underneath the saddlecloth (leather piece LD), with platelets, e.g. B. from cardboard PLK Fig. 61c can be underlaid. Fig. 61cN shows a variant in which used as a support for the palm rest is a narrow granule cushion GNLT (welded into liquid floating in another foil bag. See also the later part of the description).

Fig. 72a (cf. also Fig. 61cN, oblique view with detail GNLT) relates to an embodiment variant in which the longitudinal side of the cushion, which is opposite the superscript support, ie is not supported and therefore lies lower, is supported with a stop surface (WKL) is with the following variants: that the stop surface is resilient, the stop surface is designed as an angled strip (e.g. plastic), in which one angular surface rests on the support surface of the cushion and the other angular surface supports the movement of the cushion towards the keyboard front, that the attachment the pillow or pillowcase is made inside the angle along its bending edge, z.

The use of a Velcro strip makes the leather pad interchangeable, for hygienic reasons and for the another variant in connection with an additional one back pillow is practical.

As a further detail, which is optional, a leaf spring 33 f is placed under the cushion, which relaxes when the hand is lifted off. This changes the damping (e.g. left hand of the rail at the level of the X / Y keys on the outer edge to the left of the keyboard) of a sensor coil attached to the underside of the rail (see the previous description) to generate an activation signal for the Cursor movement by moving a pillow along the rail (e.g. the right pillow, see previous part of the description) or also for measuring the contact pressure of the hand placed on the pillow, the variant shown in FIG. 62 also for a rear pillow can be used for the arm support in addition to a front cushion for the hand rest (see later part of the description, automatic adjustment of the height of the cushion).

Fig. 68b illustrates a variant with a coating of the slider 101 or the lying on the fulcrum guide element 98 with a sliding film 101 GL.

FIG. 67a illustrates a curved version of the guide slot X, see FIG. also other variants in the following part of the description ( 102 a, 102 b... side parts with insertion slots of X).

Another Alternative for the production of the rail guide is a plate with corresponding longitudinal ribs made of plastic and glued or snapped on accordingly Sliding surfaces.

Other alternatives for running the Foil bag pillows are:

The advantage of the foil bag cushion is the cheap manufacture and that the Material does not stretch. If stretching were desired, could be as  Material for the bag z. B. rubber can be used. As Another option for the bag would be a valve for To provide inflation.

For the use of a foil pouch e.g. B. from PA / PE film is still in training provided that the film with a noise insulating Fabric cover is coated, which is preferred Embodiment of the fabric cover made of a fleece (e.g. Velor), as it is also used for Velcro tape bindings used, used in particular further configuration so that the fabric cover with a Glue is glued to the foil by ironing on when the fabric is glued to the film heated thermally becomes.

Other alternatives for the design of the Sliding surface for the sled pads of the cushion pads in Connection with variants for the guidance are:

In a further option, the slide plates can also be guided along the longitudinal center line of the slide surface with a guide bar projecting beyond the slide surface 99 (as a replacement or supplement to the guide slot). B. slide elements guided on both sides of the bar by the bar form the guide element.

For the The alternatives described form the guide element at the same time the fulcrum of the sled plate, whereby in Guide slot the trigger protection of the plate by a sliding plate below the guide slot Guide pin is given. When using a single outstanding guide bar (or guide bar) with sliding on both sides of the guide bar at the pivot point Sliding elements, which are at a short distance from the bar lie and are separated and guided by the bar, The trigger is secured by a lateral projection on top of the bar, e.g. B. also by sliding plates, the trigger protection also by means of magnetic adhesion can be made or supported: z. B. over a Magnet, which is directly over one or each more of the sliding elements is attached, and to one Sheet iron plate, which is under the sliding surface, adheres magnetically.

Another alternative is one Preferred version in which the slide plate is omitted and the sliding elements directly on the  The underside of the cushion are glued on.

In another alternative it would also be possible to customize the omit linear guide completely so that the pillow free within the frame of the guideline surface slide.

In addition to the capacitive already proposed Length scanning of the rail guide is for the Design variant with a guide bar, the capacitive scale in the form of a sawtooth Vertical stripes on the upstanding sides of the guide bar attached and by the sliding elements by means of insulated metal surfaces on the relevant sliding elements elements are attached, capacitively touched.

Other options show Figure 33b, Figure 71b, Figure 73 to Figure 75 miles....:

Fig. 71a and 71b relate to embodiments for the holding secure the slide plate guide member (see FIG. 98,. For example in Fig. 33), wherein in Fig. 71a inserted into the guide slot X capping ZPF without terminating T-piece and in Fig. 71b has such a T-piece (LA), cf. see also the following part of the description for Fig. 71c and Fig. 81 (BND... increased band as a stop).

For the rail guidance, a protruding bar (band BND) on one long side is sufficient as a twist stop of the slide plate 100 .

Fig. 73 to Fig. 75, the further construction of the cushion pad concerns with an additional slide guide in another coordinate means 99. . . Sliding surface with guide slot for slide plate 100 and sliding elements 101 ; further sliding elements (GLE) of the upper slide plate 100 -O and with sliding frame RM, 1 . . . Pillow. In addition, in FIG. 73 means: outer sides of sliding frame RM guides sliding elements (GLE) of the uppermost slide plate 100- O in the direction of the keyboard. One or more sliding element (s) (GLM) slides inside the frame, which forms the stop for the movement play of the attached slide in the direction of the keyboard.

In another Option is on one of the sliding elements, e.g. B. on  middle GLM, a magnet and the inner part the frame RM designed with an iron plate, whereby A trigger protection is formed, optionally for Possibility to do this via a guide groove.

Another alternative to this embodiment is described in the later part of the description of FIG. 69a.

As FIG. 73 further shows, for the generation of an activation signal which indicates the (brief) lifting of a hand (e.g. left hand) (in connection with an actuation of a selection key for the cursor or mouse function that takes place at this time interval) ), the spring for lifting the slide plate (in another variant) is arranged directly on the sliders (slider arranged on leaf spring) (option: 101 + 400 b) or a plastic spring sliding on the rail surface (option 400 c) is provided. (Lifting off the slide plate with the damping plate 33 attached to the underside generates a signal on the scanning coil lying under the sliding surface, as already explained in the preceding part of the description). This damping measurement can also be carried out for a large number of scanning points (cf. sheets 33 with scanning coils 34 A to 34 D in FIG. 54) with different frequencies of the coil measurement signals (filtered by parallel resonance circuits of the coils), which, for example, causes the displacement or rotation of the cushion 1 is measured within the frame (RM) for the purpose of generating a control signal for the follow-up control of the upper and lower slide plate, or also the contact pressure of the hand placed on the cushion, as will be described in the later part of the description of exemplary embodiments.

Fig. 74 shows a development in which, while maintaining the principle in addition to the sliding elements (GLE), which, for. B. make the inside of the frame, the outside of the frame sides are provided with two grooves that hold magnetically mounted balls in the grooves (KGL) on which the top slide plate 100 -O rests. FE. . . Magnetic iron plate MAG to GLM, as already explained above.

It is evident that in principle also the lowest sled plate with roller balls (e.g. spring ball bearing) or magnetically adhering ball rail, or sticking balls, can be supported.

Fig. 75 shows a top view of the rail with the cushion and an example of the dimensions: 2.7 mm. . . Guide slot; 70 mm. . . Rail width of the sliding surface, (...... Option Description: 85 mm × 65 mm dimensions cushion, 1 RUS ruffled border, 1 thinner, lighter cushion fabric made of mixed fabric Felt + pulp, 1 .Beute filled with granules); Rail 540 mm long.

Lower and upper Sled plates each have a rectangular shape rounded corners.

The lower slide plate 100 has the same width as the rail, the length is covered by the frills of the rectangular pillow. The upper slide plate is not visible in FIG. 3 and is held approximately congruent with the lower slide plate.

Fig. 24, Fig 24a, b, c, d, e. Fig. 25, 25a to 25e: Fig. 24 and Fig. 25.. . . already explained in the previous part of the description,

FIG. 25a and FIG. 25b, as Fig. 24a and Fig. 24b are distinguished by the embodiment in which the push rod 89 of the rotary plate of the pad is directly in the U-tripod support screwed once and is performed once only by the long hole.

Fig. 25c, Fig. 25d, Fig. 25e concerning further details for the product to Fig. Variants described 25, as by means of a centering as shown in FIG. 25d, (ring or individual Velcro bonding pads 93 PZ), which at a Flauschfläche of the pad stick, the pressure plate 93 is centered. Another is on the threaded rod G, which presses the pressure plate against the cushion (screwed into plate 3 , Fig. 25c), a tape (e.g. made of fabric or leather) is inserted (BDS), which the air cushion (or water cushion) inside the cushion cover ) loops and by pressing the pressure plate against the cushion (via the threaded rod screwed into the plate), press the band and plate against the cushion, or loosen them again in the opposite direction of rotation of the threaded rod, whereby the pressure in the cushion can be adjusted. FIG. 25e shows a further variant in which the inclination of the cushion with a thumb screw within a guide slot (86) is adjustable a supporting device.

In FIG. 61b and FIG. 25c it is further illustrated how, instead of the handle 84, a drive wheel 84 AT is flanged to the threaded rod and the adjustment can be carried out by means of a corresponding transmission by means of a motor ( 84 M).

Further optional further developments: Fig. 60d shows a further embodiment of the pillow (with entered dimensions in mm) with the detail that short seams are welded inwards from the long sides ( 4 a, 4 b, 4 c), which overlap one another Hold the film surfaces of the bag together at these points, whereby the shape of the troughs 10 on the side of a crest MB, (dimension 12 ) ensure good adaptation to the hand or armrest.

Fig. 60a, Fig. 60b and Fig. 60c illustrate a development variant, in which for the rotation of the pad an elastic restoring force is generated, depending on whether or not the hand is placed on the pillow not. The restoring force occurs when the cushion is relieved (reduction of the pressure on the hand or lifting of the hand). This is expedient if the pillow loses its guidance by twisting during typing, whereby it is automatically turned back by relief.

If the hand lies on the pillow, then is the torque of the spring force that the cushion in a certain rest position (e.g. parallel or at an angle to Keyboard front line), completely decoupled Hand mobility is therefore not hindered.

The technical task was solved by special Formation of the slide slot in the rail surface guided guide or sliding element, such that by Leverage against the guide slot or web, a return torque generated by the spring force Is generated with a coupling of the Torque so

• a) that one against the tracking force the hand-acting spring force is provided with a Travel, which when removing the palm rest (lifting the  Hand) the distance of the slide from the sliding surface Relaxation over the travel increases as well
• b) that the guide surface of the guide element (e.g. lateral surface of the sliding pin between the upper plate and lower plate of the trigger protection) has two different cross sections via the spring travel:
  • b1) over the section of the guide surface, which is guided by the guide rail (e.g. sliding slot) when the hand rests, ie when the spring force is tensioned, the cross section of the guide surface (or the sliding pin) is designed such that the sliding element around it The guide surface can be rotated (e.g. slide pin = axis of rotation of the slide),
  • b2) over the section of the guide surface, which is guided by the guide rail (e.g. slide slot) when the hand is lifted, ie when the spring force is relaxed, the cross section of the guide surface (or the slide pin) is designed so that the slide element on one (in vertical direction) deviates from the perpendicularly aligned inclined surface, and that the angle of this inclined surface with respect to the vertical position of the axis of rotation of the slide, starting from its point of intersection with the axis of rotation, opens downwards (triangular tip of the angle above, opening downwards) , whereby by lifting the axis of rotation in the corresponding travel range by reducing the contact pressure of the hand or lifting the hand, the distance between the guide surface and the inclined surface is reduced, ie a torque is applied to the slide plate by lever action on the inclined surface, thus the cushion in a fixed reset direction is turned.

Two versions are described below:

Fig. 60a and Fig. 60b shows side view of the variant in which the inclined surface or wedge surface of the guide edges of the guide slot 106 in Fig. 60b) extends over the entire length on both sides of the rail guide, whereas the slide member need not have a sloping surface and the pull-off of the sliding element with two points of contact forms a lever on each side of the slot (as already explained).

In contrast, in the embodiment according to FIG. 60c, the plate surface provided as a protection against pulling off the sliding element is designed as a vertical wedge surface (corresponding to a triangle that has been set up), the inside guide slot edges not having to have any inclined surfaces.

The variant of Fig. 60c is slightly less expensive and requires but for a slightly higher height than variant according to Fig. 60a and Fig. 60b.

To Fig 60a and Fig 60b..:

Fig. 1a shows the position in which the cushion is relieved, or the hand is raised.

Fig. 1b shows the position in which the cushion is relieved, or the hand is raised.

It means:
103 . . . cardboard plate laminated with foil paper (cellophane-coated cardboard),
99 . . . sliding surface strips running on both sides of the guide slot 106 ,
101 . . . . supporting sliding elements (with curved sliding surfaces on the underside), 103 b. . . Support bars for fastening 99 to 103 ,
102 . . . Longitudinal edge strips (cant at the edge = band = stop).

The wide strips on the end face of the rail guide are removed in the illustration according to FIG. 1, the wide strip optionally has an opening which exposes the guide slot (cf. 106 in FIG. 60b) for inserting the slide plates.

400 . . . optional, leaf spring or leaf spring pair, on which the guide element 98 , which also forms the axis of rotation of the slide plate, is suspended, optionally available, for. B. as a pressing force when an electrode surface (concentric circular ring 73 b, cf. previous part of the description) presses against a capacitive length scale 69 A, 69 B.

The leaf spring is dimensioned such that when the slide plate is lifted (hand raised), that is to say when the leaf spring is relaxed, it assumes the position shown in FIG. 60a, that is to say, in the relaxed state, it has an exact spring travel, which is characteristic of a leaf spring.

400 b. . . likewise leaf springs or spiral springs, on which the supporting sliding elements 101 are suspended on the underside of the slide plate 100 and act like a shock absorber.

98 N . . Trigger protection modified according to the invention of the guide element 101 used as the axis of rotation, the trigger protection having approximately a rectangular shape, the pairs of front corners of which are in each case the contact surface for a lever effect for generating a torque. This torque is generated by the upwardly tapered sloping surfaces 103 S of the inner edges of the guide slot (formed by reinforcing strips 103 N), the engagement surfaces of the rotary lever 98 N being centered by this sloping surface when the slide plate is raised (kl = maximum), as a result of which the axis of rotation of the guided sliding element 98 is rotated into the defined rest position. The slide plate is raised by the spring force of the supporting sliding elements ( 400 b with 101 ) so far (q) that the surface of the trigger protection 98 N on the underside of a narrow horizontal groove 103 X lies on both sides of the guide slot on the inside on the underside. Furthermore, the distance to the support plate 103 of the guide rail is kept so far that the guide element 98 can be pressed down.

Fig. 60b shows the (with path q, see Fig. 60a) pressed down sled plate with tensioned shock absorber springs 400 b, in an angular position β, which corresponds to the angular range of the sled plate (released by the downward opening of the Bevel 103 S of the guide slot edge), whereby in this position there is no spring force in torsion direction β!

The alternative embodiment according to FIG. 60c corresponds to the function according to FIG. 1, however, the inclined surface is not realized by the edge of the guide slot widening downwards, but rather on the sliding or guide element, in which instead of a plate edge acting as a trigger protection, the Edge surface of a downwardly extending vertically positioned triangle is provided, at the upper tip of which acts as the axis of rotation of the slide plate guide pin of the guide element 98 is flanged. If the pen is lifted upwards (direction of arrow), the triangular surface adjusts itself accordingly due to its inclined surface (angle of rotation in direction of arrow), whereby the cushion or the slide plate is brought into the reset position. A widening of the triangular surface 103 S or a corresponding flange-mounting of a further plate surface is provided on the underside as a trigger protection.

As a further variant nor the combination of the embodiments of FIG. 1 and FIG would. 60c possible (inner edges of the guide slot 106 with wedge surfaces 103 S, as well as the wedge surface on the guide pin of the guide member 98).

Below is another embodiment with extended task described.

The further education fulfills the technical task that the pressure of the hand placed on the pillow or the ball of the hand or wrist is substantially alleviated. This is achieved by using: a plurality of pillows 1 -V, 1 -H arranged one behind the other, which can be moved directly to the keyboard front by shaping the pillow and / or by sliding the pillow support.

All of the design components explained in the preceding part of the description can be used for this further development, with particular suitability for the example described with a skid runner principle, with one or more cushions for the hand rest, the contact surface of which is in each case as a slide ( 100 , cf. which in an aligned in the longitudinal direction of the keyboard front sliding surface (99 and 99 -O) z by means of sliders (. B. on both sides of a guide groove X or a guide web slides, and by the guide groove (or guide bar). Fig. 69a) via a Guide element 98 is guided and the rotatability of the guide element within the guide groove (or over the guide web) also forms the fulcrum and for the cushion support of the front cushion ( 1 -V with 100 p... Upper slide) another coordinate guide 99 B in the further coordinate direction (vT, see FIG. 69a) in the transverse direction to the guide direction of the guide rungsrille (or the guide bar) is provided.

In a further preferred alternative, the rocking principle of a rocker cushion is used as a further embodiment variant for the transverse movement of the rear cushion 1 -H, as an alternative to the sliding principle of the front cushion 1 -V.

To one hand to correspond to the widespread hand position, on the other hand also a disturbing feeling of pressure on the back cushion Avoid arm at the support point are the following further versions or further training variants described.

In addition to the possibility for each hand, in principle a large number of movable cushions in a row, with two cushions ( 1 -V... Front, 1 -H... Back) a very good effect in the sense of technical task achieved.

Variants for the movement coupling of the rear cushion 1 -H to the front cushion 1 -V are that the coupling takes place only mechanically (e.g. Fig. 79), or via electronic control (cf. Fig. 97), whereby for both cases the variant is provided to make the mechanical connection by a static connection of the support, which can also be designed as a joint (with a horizontal axis), or to be carried out directly by the arm of the correspondingly placed hand.

The front cushion 1 -V, which affects the palm rest in front of the wrist and slides directly along the keyboard front (from keyboard 8 ) on the preferred sliding surface, is small and low, with preferred dimensions of approximately: 8 cm in the longitudinal direction of the keyboard, 4 cm width (BK) and approx. 0.5 cm to 1 cm high (h), cf. Fig. 97 so that it fits comfortably in the hand. In another option, the front pillow is designed as a flat foil bag (e.g. PA / PE), which is filled with spherical plastic granules of a softer plastic that float in liquid (see the description above) and thus adapts well to the hand placed on it (option : corresponding to window opening 1 -FV for the leather cover of the foil cushion, Fig. 97). The pressure relief of the hand placed on the front pillow 1 -V takes place through the armrest of the pillow 1 -H arranged behind it, the rear pillow 1 -H, for example, as the preferred rocking pillow (cf. FIG. 77) and the front pillow 1 -V as against the keyboard front on a further slide ( 100 S, Fig. 69a) in another coordinate device vT displaceable cushion is executed.

The rear pillow 1 -H, designed as a rocking pillow for the armrest behind the wrist, is designed in accordance with the previous explanation and consists of a film bag (e.g. PA / PE) that is only partially filled, e.g. B. with gas (z. B. air) or a liquid (z. B. water) and through its flat support forms a trough in which the arm (see. Fig. 97) can be inserted. According to the previous description, the cushion is raised slightly at the back, so that the trough is formed at the longitudinal seam of the bag, as a result of which the rocker roller of the cushion is formed. Design of the pillow case (fabric 1- H folded upwards covered with fleece tape 132 at the top and with leather saddlecloth LD) corresponds to the front part of the description.

In order to bring the arm resting on the rear pillow (behind the wrist) in line with the palm rest of the front pillow (flat) to the front pillow or the keyboard, the rear pillow is designed to be higher than the front pillow, set somewhat lower ( 100 m in Fig. 97, with a distance of 100 V behind the front pillow).

An embodiment is described below, in which the sliding surface for the pillow arrangement of the front pillow above the edge of the table on the table in front of the keyboard has to be set up without the keyboard having to be raised and the pillows behind the hand rest pillow 1 -V for each Armrest ( 1 -H, behind the wrist) protrude freely from the table top, which means that the device can be parked on the table to save space and there is also a level adjustment option for the armrest (of the rear cushion).

Two different variants are provided for coupling the displacement path of the front and rear pillows:
A first variant for a low-cost version, in which the movement coupling of the front cushion 1 -V and the rear cushion 1 -H takes place by static connection of the cushion contact surfaces, and a second variant, in which the coupling of the front cushion and the rear cushion by means of motor-driven motion accordingly sensory movement sensing of the pillow (e.g. via displacement path) with regulation of the respective deviation from a desired position of the movement sensing.

The variant of the electronic readjustment of the rear The cushion on the movement of the front cushion is then off essential advantage if the back pillow instead of Air, e.g. B. is filled with water, because then Moment of inertia of the rear pillow becomes very large.  

Motorized drive and scanning of the displacement relevant contact surfaces of the pillows is ent speaking already proposed embodiments of the front part of the description, with the linear drive the sled plate in the longitudinal direction of the keyboard, additionally a drive for the movement of the upper one Carriage plate in the transverse direction by means of the carriage plate combination of self-sufficient motors can be made ditto a servo-controlled Rotation control of the sled plates.

Preferably, a transverse rail guide 99 B is provided for the front flat cushion in addition to the longitudinal rail guide 99 or 99- O, by means of which the flat cushion is moved in the direction of the keyboard front during typing.

In addition to those already described in the foregoing partially disclosed design options for this further coordinate movement of the pillow is as follows detailed version particularly preferred:

The slide plate 100 sliding in the longitudinal direction of the keyboard front on a sliding surface 99 by means of surface-separated sliding elements 101 is also designed as a sliding surface, like the sliding surface on which it slides, on which further sliding surface strips are placed directly or via superimposed (see 99 -OSL in Fig. 83 and FIG. 76b) a further slide 100 S slides in the direction of the keyboard front.

In an optional further development, the sliding surfaces for both of the superimposed slides 100 and 100 S are inserted as exchangeable strips in a frame, as described below for FIG. 80 for the lower slide plate 100 and in FIGS. 83 and 76b for the upper slide plate 100 S .

The frame for the sliding surface of the lower slide plate consists of a foil-laminated cardboard plate ( 103 in Fig. 80, see front description part), which forms the underside (footprint), on which increases by means of narrow webs aligned parallel to the keyboard front (e.g. from Wood, 103 b), strips 99 are glued on both sides of the guide slot X in the longitudinal direction of the keyboard as thin plastic strips. These plastic strips 99 form the contact surface for the replaceable, actual sliding strips 99 -O (e.g. made of particularly smooth, hard, transparent PVC), which snap into the frame of the sliding surface 102 , or are also pushed under the contact surface (option, cf. later).

The two long sides of the frame for the slide rail support (e.g. strips made of wood or plastic) are dimensioned such that when the slide strips 99 -O, which forms the slide surface of the slide, are placed, at least one side has an increased band for the stop of the slide elements the rotation of the slide plate (see front description part). The side delimitation bar on the front broad side of the slide rail support is flush with the inserted sliding surface (cf. front description part) to enable the slide to be inserted laterally into the guide groove, with a corresponding slot (B, Fig. 81) in the middle for insertion of the guide element ( 98 , Fig. 80), which also forms the fulcrum of the slide plate, is provided with stop limits which can be pushed into the guide slot (strips ZPF, Fig. 81).

Furthermore, it is optionally provided to place 99 -0 points made of mushroom tape (Velcro tape) on the underside of the longitudinal strips placed as a sliding surface, which stick to Velcro strips, which are correspondingly embedded in the contact surface 99 . Instead of this adhesive connection, a magnetic adhesive connection can also be used, or an adhesive connection can also be dispensed with, or the framing 102 can, for. B. have corresponding adhesive grooves for the lateral insertion of the sliding surfaces 99 -O.

The cross slide that can be moved towards the front of the keyboard is designed in a special version as follows:

On the lower slide plate is for longitudinal movement on the top is the sliding support of the cross rail provided with the slide plate center line on both sides perpendicular to the keyboard front Guide bars or strips (increases), each with a further increase, which on the longitudinal edge of the The guide bar protrudes, are covered, whereby the cross rail guide with an edge groove on the underside  Protection against deduction of the cushion cover is formed. The Leading edges of the cross rail guide are either on the inside of the parallel guide bars or enclosed on the outside by sliding elements, the vertical pins of the sliding elements, along the edges the top bar of the cross rail web on the inside or are guided on the outside and at the bottom of the vertical pins placed on the sliding plate in the underlying guide groove of the leading edges Slide half in the groove and through the groove are protected against deduction. The sliding elements for the Cross rail guidance are then at the bottom of the actual support surface for the pillow, or attached directly under the pillow.

In addition to the possibility of providing wheels as sliding elements (cf. FIG. 94), the already explained sliding elements, e.g. B. made of POM (polyacethal resin) in plate form and pill form. The trigger protection is formed by the plates of the sliding elements, the guide centering by the pins, whereby the plates can also perform a vertical support on the sliding surface of the slide plate, or without vertical support, only a centering and trigger protection is made, using further skid-shaped Sliding pills or mounted sliding rollers for vertical support. Variants are explained for FIGS. 83 and 76b.

For the cross slide, the actual sliding surface is also interchangeable and an insert in the form of a plate 99 -OSL inserted on the underside of the guide groove edge made of the same material as for the sliding surface of the longitudinal rail guide 99 -O.

This plate adheres to the sled plate, for example via Velcro and has the stop limit of the sliding elements at the front and rear edge when the support surface of the front cushion is displaced in the direction of the keyboard front, or the typist, e.g. B. in the form of a final bar, or is inserted separately from these stops in the guide webs ( Fig. 83. Fig. 76b).

The attachment for the support surface 100 AP of the rear cushion 1 -H can either be done by simply extending the lower 100 or upper slide plate 100 S to the rear, or can be made interchangeable for a wide variety of needs, e.g. B. for the optional inclination of the support surface of the rear cushion with an inclined angle to the installation level of the keyboard. The interchangeability can e.g. B. done so that two sled plates for the lower sled are tacked together via Velcro and the extension 100 V inserted in the space between these two sled plates for the support surface of the cushion and fixed via an interchangeable bolt connection or further Velcro connection.

Another special feature is, after a distance which corresponds to the space for the rotatability of the slide plate 100 V, to provide an angled portion of the plate shoulder 100 M for the support surface 100 AP of the rear cushion 1 -H at the plate edge, e.g. B. at a right angle downwards (wall 100 W in Fig. 109, or angle M in Fig. 77) and on the contact surface of the rear cushion also provide a corresponding bend ( 100 N, Fig. 69a), the two bends are connected by means of an elongated hole connection ( 100 M in Fig. 6, 69 a, Fig. 78) or sliding connection or spindle drive, which allows an adjustable height adjustment ( 100 W, Fig. 79) of the rear cushion compared to the front cushion for lowering; e.g. B. fixed with wing screws 701 , the liability z. B. can be optionally reinforced by Velcro connection between the superimposed plane surfaces of the angled plate edges, or by servo control, as described later.

The rear Cushions stick to the plate along a rocking line, which with Velcro tape connection KLT on the cushion cover is produced (see front description part).

The rail guide is fixed to the table preferably by means of tablecloth holder clips 702 or screw clips 702 -ST and / or by suction cups embedded in the support surface of the rail, or also by removable adhesive tapes.

The tablecloth support brackets 702 have on their upper side a Velcro or fungal tape strips coating which adheres to attached to the underside of the rail guide Flauschbandstreifen, or can be inserted in the longitudinal side portions of the Gleitflächenrahmens, be described as follows (Fig. 91a and Fig. 91b).

According to the front part of the description, the guide groove of the rail guide does not have to be aligned in a straight line, but can have a curve shape, as z. B. corresponds to the ergonomic shape of modern keyboards (cf. front description and Fig. 107, Fig. 110, Fig. 88, Fig. 86).

Furthermore, right and left pillow also run on split rails, whereby the left rail part because of the lack of function keypad is shorter.

For keyboards, whose keypads are not lined up in a straight line are the long side of the sliding surface, which the Rotation stop of the slide plate for the Corresponds to sliding elements, as well as the guide groove (or Guide bar) adapted to this shape.

Another variant is also to provide the underside of the downward-facing support plate of the rear cushion with sliding elements and to support it on a further sliding surface ( FIG. 87b). This further sliding surface can, for. B. on the underside of the rail guide (z. B. the film-lined cardboard) can be pinned (z. B. by means of Velcro), or inserted laterally, with an adjustable height adjustment for the support plate of the rear cushion, between the other for level compensation Sliding surface and the rail guide, by adjusting screws, or spacing plates are provided, or an automatic adjustment by means of a horizontal joint connection axis (GLR in Fig. 87b).

Further variants are to attach the further sliding surface angled to an extension of the long side of the sliding surface frame ( 102 , 704 in FIG. 87b and FIG. 87c) lying vertically downwards on the table edge via slot adjustment 701 , or also a motorized height adjustment of the rear cushion 1 - H as described later (see FIG. 77). Another option is to provide the further sliding surface of the rear cushion with its own rail guide 99 -H, which is identical to the rail guide of the front cushion 99 -RV ( Fig. 87c).

For the variant with readjustment by motor drive for the motor support of the cushion movement there are several variants:

• a) front pillow and / or rear pillow have a displacement transducer (equivalent to FIG. 76b)
• b) front cushion and / or back cushions are motor driven (see. Fig. 79, Fig. 89 and Fig. 93 with Fig. 78).

The two options from (a) and (b) can meet the respective needs be combined accordingly, z. B. by the Front pillow transducer the front pillow itself is motorized, and / or that rear pillow is also controlled accordingly; dito optionally, the back pillow with another self-readjusting itself, or also in the after-control function of the first pillow is involved.

To generate a controlled variable is for the displacement sensor of the pillow in addition to the coordinate shift availability of movement control, a slight movement play VSP in the longitudinal direction of the keyboard (or in other Directions cf. later) provided with sensory Implementation of the shift path within this Movement play, in a controlled variable. The is created additional displaceability VSP by spacing the Guide elements from the leading edge, or through another slide attachment.

In a further exemplary embodiment, the VSP motion game by a frame whose opposite sides the guide bars for the  Form displacement of the cushion to the keyboard front (perpendicular to the keyboard front) and the other pages (parallel to the keyboard front) the stops for the Shift. In further training, this framework is in one inserted another outer frame, the inner Frame to the (e.g. perpendicular to the keyboard front standing) guide sides of the outer frame a game VSP has within which it can be moved. The Slidability of the inner frame on the slide surface can continue through sliding elements or balls be improved.

The determination of the shift of the Pillow within the movement game (VSP) to the stationary guide bars on the slide plate detected by inductive sensor, z. B. from in principle described in the front part of the description Attenuation measurement of a coil on an electrically conductive Substance, e.g. B. sheet metal strip, use is made, and the metal strips instead of the frame in question can be attached directly in the cushion (air cushion) (e.g. also without the frame in the case of immediate Sensing the rocking motion of the pillow or use elastic ribbons for the pillow cover, ribbons e.g. B. provided with metal mesh or pillowcase itself provided with metal mesh). The sensor is designed that following movements of the inner frame against the Sled plate can be distinguished: displacement parallel to the right or left, or twist. To for this purpose there are metal sheets on every corner of the frame arranged with provided on the sled plate matching scanning coils. The damped vibration is in converted an actual quantity (see above), the Actual size of the pairs diagonally opposite Coils and the one immediately opposite in pairs Coils are given to a differential amplifier, so that a parallel displacement of the carriage, as well its rotation as analog voltages of the difference ver stronger outputs is recognized. Is used as the actual size e.g. B. the output frequencies more voltage controlled Oscillators (VCO) as signal converters for the damping measurement and measurement of the frequencies or their period duration  with a microprocessor, then the difference evaluation also be done directly arithmetically.

The motorized movement control of the pillow is done as already explained, using cables such that the sensed displacement of the pillow immediately, or balanced over its management framework is, whereby the shifting movement on the one hand by hand over a very small and low-friction displacement path (Displacement play VSP) is controlled (sampled by the Sensor), on the other hand motor (without the application of force Hand) over long distances with constant regulation of the Displacement game (VSP) is executed.

It is evident that in addition to the simple longitudinal displacement of the Cushions, including the rotation of the cushions by the servo motor can be supported since the twisting of the Pillow movement through the frame or a specially provided radial rotation (by means of play and sensory scanning of the end points of the game) can be scanned, with a servo motor Twist accordingly.

Furthermore, it is evident that for the sensor only simple stop contacts (with two-point control) or springs (e.g. Inductance measurement of spiral springs) can be used can.

The power supply for the sensor scanning, if necessary also local drives, including their control signal routing and the signal routing of a serial digital signal emitted by the sensors, takes place in a further development variant via the pulling cables 45 , 46 on the guide element (in the guide slot), which also each Form axis of rotation 98 b of the slide plate, pull on both sides (via sleeve 98 S, Fig. 79).

For this purpose, for right and left pillow z. B. also separate guide slots X1 and X2, which are separated from one another by an insulating web 99 M for the bare pulling cables, can be used (see FIG. 90), or the rails are divided accordingly (see FIG. 88) into areas for the right Hand and left hand, whereby at the inner ends of the rails, where the areas of the right and left hand meet, pulleys 49/48 UR are provided for the pull cables ( 45 , 46 for each side), the drives are therefore on the outside on both sides the keyboard can be attached (within housing 54 , Fig. 88 and Fig. 89).

The two-pole signal routing (K1S, K2S, Fig. 89) of the signal coupling of the supply voltage and sensor signals, which are carried out jointly via the pulling ropes, if necessary also control signals, for further servomotors which are accommodated on the slide plates in a self-sufficient manner, takes place e.g. B. via a central clock signal, which can also be supplied to several participants (on the sled plate electronics), for short time intervals according to a time protocol of the clock signal otherwise supplied by the voltage supply coupling of the pull cables is switched to high resistance and by participants connected to the pull cables (the sled plates electronics E the pillow) is continued in synchronous transmission.

From the rectified clock signal the supply voltage is obtained, furthermore it contains Clock signal phase jump encodings (such as in Modulo-2 method or modulo-n), the duration of which is the Use the state indicated by the phase jump indicates e.g. B. that the polarity of the serial data changes, or a defined pause follows in which a Participant transmits sensor data to the control center, or Reset pulses for the internal counting clock of the participants, which z. B. by wired-or-link to certain Meter readings, these meter readings from a control center transmit, as an alternative or supplement to one immediate serial data transfer or addresses sation. The synchronization for the respective bus switching of the participants is done by the counting cycle (= Data contact, e.g. a modulo 2 process) with Breaks after a compulsory sequence in which the participants one after the other and a protocol process.

Another training development relates to attaching a compartment to desks which the keyboard is set up to advance the pillow  to accommodate quickly under the desk. It it is common to provide pull-out compartments for this purpose. Preferred further training designs relate to the feature that the compartment for the placement of the pillow device can be inserted under the desk on the one hand, or in alternative training from a usage fixation can be folded out, and in accordance with the invention Training continues along the length of the table edge Desk is slidable so that the support direction shifted along the desk at any time can be. As a rail guide is described Made use of the sliding element principle, the Sliding elements supported on both sides by sheet metal Rail rails are included that hold the sled plate that receives the pillow device, like a Include sandwich.

Below are exemplary embodiments with reference to the figures described; the description is not chronological according to the figures, but appropriately according to technical Function. The entered dimensions in mm are guidelines for preferred version.

Fig. 97 shows an oblique view of the front (1 -V) and rear (1 H) cushion, said rear cushion, and front cushion each slide on a rail surface (99 forward, 99 H or rear). The rear rail is set at a corresponding distance of 100 V to the rear and further down 100 W, which gives 100 AP clearance to the rotatability of the rear support surface of the cushion and, furthermore, by lowering the rear support surface, the level of the rear cushion, which is Version (seesaw roller) would be higher, to which the front low cushion is well adapted. This adjustment is carried out in different variants individually by hand, or by motor, or also by motor, adjustable.

The variant of Fig. 97 relates to an embodiment in which the rear cushion by motor servo drive in the longitudinal direction of the keyboard front, or the rail, it follows readjusted hand movement, thereby z. B. is possible to fill the pillow with a liquid instead of air, since the high inertia of the pillow is compensated by the motor drive, and no longer stresses the hand.

A very cost-effective variant with a combination in which the front cushion 1 -V is designed to be displaceable in the form of a flat cushion on a sliding surface both along the keyboard and against the keyboard front, and the rear cushion 1 -H as a rocking cushion, in particular with Air filled, executed, with a static coupling of the support surface of the rear rocker to the lower slide plate of the front cushion, guarantees the following advantages:

• a) the rocking of the rear Pillow transfers to the front pillow in such a way that much of the potential energy generated by the Hand weight is caused by the redirected Movement of the hand in kinetic energy is converted
• b) by the easy execution of the large-volume rear cushion as an air cushion and the small, low front pillow with the filling of one floating, soft round plastic granules follows the back pillow on the one hand almost the front pillow without inertia, the granulate filling of the front pillow by the interaction of the one Liquid floating granules and that through the rear rocker cushion reduced contact pressure a fine Hand massage, which because of the low contact pressure as is felt pleasant.

Fig. 87a, b, c and Fig. 78 illustrate different variants, Fig. 87a shows a variant in which the support surface of the rear cushion is flanged to the support surface of the front cushion and the support of both cushions only on the sliding surface of the front cushion takes place, therefore the underside of the slide guard in the sliding slot is loaded against the underside of the sliding surface, depending on the respective hand position.

In FIG. 87b, on the other hand, the support surface 100 -AP of the rear cushion is additionally supported by a further sliding surface 100 -UP, which is supported by the frame 102 of the front sliding surface (via vertical extension 704 ).

Fig. 87c shows a side view of a variant with double guide rail by their own Gleitflächenlineale for front (1 -V 99 -RV) and rear (1 -H 99 -H) Pillow according oblique view in FIG. 97. If, however, Fig. 97 according to variants corresponding to FIGS. 87a and 87b, then the sliding surface ruler of the rear ( 99- H) cushion is omitted, or for the variant according to FIG. 87b a ruler is used instead of the sliding ruler for the further sliding surface 100 -UP, cf. also Fig. 115.

Fig. 78 shows the side view of an embodiment according to Fig. 87a, in this variant the sliding surface 99 of the rail guide is loaded both on its underside via the trigger protection (plate 98 ) of the guide element at the edge of the guide slot ( 99- f, slot X), as well as from the top (via skids 101 ). Guide element 98 slides in slot X and at the same time forms the axis of rotation of the lower slide 100 , on which the further slide for the transverse movement of the cushion 1 -V is placed in the direction of the keyboard front.

The pivot point is therefore made on the lower slide, while the upper slide allows the hand to move towards the keyboard (in conjunction with the rocking motion of the rear cushion). By optimizing that the pivot point of the front cushion occurs on the lower slide, it is possible to flange the support surface 100 AP of the rear rocker cushion 1 -H directly to the lower slide plate 100 via a height adjustment 701 by a simple angling (via extension 100 V), and thus to allow the rear rocker cushion to rotate well without an additional sliding surface for this cushion, and furthermore to keep the leverage force for the load on the trigger lock 98 (at point 99- f) low ( FIG. 78), further by using a rocker cushion for the rear cushion as an armrest, the leverage of the arm moving back and forth in the direction of the keyboard front is limited with good mobility of the hands for typing.

Due to the simplicity of the design, the variant according to FIG. 78 corresponds to an inexpensive function-optimized design.

Details for execution variants of the lower slide plate 100 mounted upper carriage 100 S for the front pad 1 -V, with skids 101 -OS illustrating the Fig. 69a, Fig. 76b, Fig. 83 and Fig. 93rd

Fig 82 on the other hand. The lower slide plate 100 is removed by sliding guide for the upper carriage (see FIG. 100 S in FIG. 69a).

The guide of the upper carriage is made to a structure corresponding to FIG. 83 or Fig. 76b so that the vertical pins b 101, each sealed with an acting as a trigger safety plate guide members 101 -OS to both guide sides of the upper carriage with lateral rail guide edges 99 B are enclosed with the front edge and rear edge of the lower carriage stops (see FIG. stop strips or pins, 703 and 705 in Fig. 93, Fig. 97 and Fig. 69a) for the guide elements for limiting the path of displacement of the upper carriage.

In addition to the variant, the upper slide 100 S directly on the underside of the plates acting as a trigger safeguard ( 101 c in Fig. 83 or 98 B in Fig. 76b) of the centering pins ( 101 b of 101 -OS, see Fig. 83) To allow sliding on the sliding surface of the lower slide 100 , a spacing between the underside of the sliding plate 98 B and the sliding surface of the lower slide is provided as a further variant. This spacing is carried out by skids 101 -GS, which are attached to the underside of the upper carriage on the outside of the guide elements 101 -OS on both sides and only provide vertical spacing support. Lateral support is provided by pins 101 b.

In both variants, it is possible for the expansion option of a motorized readjustment to provide the upper slide with a backlash VSP, as explained above, and which is scanned by means of an inductive damping sensor in order to obtain a direction variable in which the lower slide can be readjusted by a motor must to compensate for the frictional force between the lower slide and its sliding surface 99 .

Embodiments according to FIGS. 76b and Fig. 83 can be performed with both sensor scan of a movement play VSP or without movement play in sliding fit.

The differences between the variants according to Fig. 76b and Fig. 83 relate to embodiments in which, in Fig. 83, the lateral mobility VSP of the upper slide plate by the corresponding distance between the guide members 101 -OS of the transverse rails guiding edge (99 B toward the front keyboard) directly by the guide elements (pins 101 b of 101 -OS) occurs while in variant according to Fig. 76b, the guide members 101 -OS for lateral rail guide 99 B have a Gleitpaßform, and the lateral rail guide are designed as sides of a frame RM, within the Guide elements 101 -OS slide and rest on the inside on the frame sides. For this purpose, the outer sides of the frame RM have a play of movement (VSP in FIG. 76 b) to further guide sides, which are placed on the lower slide plate 100 . In variant according to Fig. 76b thus is also still a frame RM with play VSP between the lower slide plate 100 and upper slide plate 100 S inserted, which frame is supported also on skids RMGL or balls (KGLn, Fig. 96) for example, interchangeable slide plates.

The scanning of the lateral movement of the upper slide plate within the movement play VSP takes place for both variants in such a way that metal sheet strips 33 (in FIG. 83 on the underside of the upper slide plate 100 S, in FIG. 76b on the underside of the frame) are attached, to which by means of coils (the electronics E) a (eddy current) damping measurement is carried out, and the amplitude damping carried out by electrically conductive sheets 33 is assessed as a measure of the displacement VSP.

The electronics E with the sensor coils are then accommodated, for example, inside the rail guide 99 B of the upper slide, which is placed on the lower slide 99 , or in the remaining free spaces of the lower slide plate. The signal feeding the traction cables to the carriage plate is carried corresp. Fig. 79, wherein the guide member comprises b 98 a hollow axle 98 through which the contacted terminals of the traction cables 45, are passed 46 from below (AZSU) to top (AZSO).

Furthermore, only the frame part of the pillow ball, which can be displaced in an additional movement play VSP, can be mounted (in ball grooves, see front description part) and, through motorized support of the moving parts mounted on sliding elements, the sensitivity of a ball bearing device for the pillow movement guide can be achieved for the entire device be (see Fig. 96).

Likewise, e.g. B. as an alternative, the rear cushion 1- H can additionally or alternatively be made to be a rocking cushion, can be made movable by means of rails guided device in the direction of the keyboard front.

In Fig. 76b, an embodiment in a further development is presented with a scale, by means of which the contact pressure of the hand on the front pad 1 -V for the purpose of an automated adjustment of the height adjustment of the rear cushion 1 -H (see. Fig. 77 below) is measured, is: For this purpose, the upper slide plate for the support surface of the cushion 1 -V has a frame opening, which is covered by a flexible plate 633 made of spring sheet metal or with a metal-coated flexible plastic plate and this plate 633 forms the support surface of the cushion, with a deflection corresponding to the contact pressure of the pillow. This deflection is measured via a coil (L6) located underneath, which is arranged in the window of the support surface and which performs a damping measurement on the metal plate 633 , as is done to determine the displacement of the upper slide plate within the movement play VSP (optional or supplementary) .

Fig. 79 illustrates a proposal for the attachment of the pull cables 45 , 46 (see also advance notification) directly on the guide element 98 of the lower slide plate via a bush 98 S, in which the guide element is rotatably supported by the extension of its vertical guide pin 98 b .

Fig. 82 shows an example of the plate of the lower carriage 100 (front cushion) corresponding to 77069 00070 552 001000280000000200012000285917695800040 0002019507797 00004 76950 position drawing according to Fig. 69a. 703- KLT and 705- KLT are hook-and-loop tape connections to the velcro surfaces adhering to them for flakes to be attached, as shown as an example in FIG. 93: these flakes each have the stop bar 703 and 705 at their ends to limit the displacement of the upper slide plate.

Fig. 82 also illustrates how the skids are inserted into the plate: the skids 101 each consist of slidable material (e.g. POM) in pill form ( Fig. 82b), which protrude from the underside of the plate towards the sliding surface. These pills are each inserted into a slot 101 ES sawn from the edge of the plate (see also FIG. 79 on the right), this slot being closed or covered on the top side of the plate (strip or sheet 101 -HLA, FIG. 79). and closed from the peripheral side at the bottom, and covered 101 HLT, (see. also Fig. 84 and Fig. 85), so that the pill is the one hand, on the other hand, enclosed by the inserted sawed slot 101 ES of the plate of the cover strips. As FIG. 82 still shows, the slot 101 ES for the sliding pills 101 is inserted at an angle (y) which is dimensioned such that the flat end faces of the sliding pills abut the edge strip which acts as a stop for the sliding pills when the slide plates are facing Stop position are rotated. The round cylinder sides of the pills act as skids or rollers, the pills also being able to have rolling axes (e.g. also for cross slides) or being inserted in a fixed manner.

This is done below a compilation about the figures that the previous chapters of the description relate to further explanation of the reference names, if they have not yet been explained.

Fig. 69a shows a plan view of the carriage combination of lower 100 and upper 100 S b carriage with removed pad (Velcro connection KLT) with the flange-mounting plate 100 for the rear cushion AP.

Fig. 77 shows the continuation of Fig. 69a regarding the flanging of the rear cushion 1 -H with a top view and side view and rocking line KLT (loop tape, adheres to crossed Velcro tape / mushroom tape tape 40 a, leather-covered foam strip (HSL) also with velcro underside adheres to 40 a (adjustable).

In Fig. 77, a proposal (shown cf. wing screw 701. FIG.: To this end, the elongated hole slots of adjustable height butted parts 100 M and 100 N are) for the height adjustment of the rear cushion 1 H as an alternative to manual adjustment by a dovetail or similar Fitting of the parts replaced, or directly by paired execution of a motorized spindle drive (M5a, M5b) in its relative height adjustable static (see Fig. 109), as the version shown in Fig. 77 shows: two motors arranged side by side (M5b behind M5a; M5b is covered by M5a in Fig. 77, see also Fig. 109), a threaded sleeve / spindle combination rotates in opposite directions, one of which has a left-hand thread and the other has a right-hand thread, whereby the torques of the spindles are compensated for with the same linear feed paths.

The spindles are screwed into sleeves, with one end of the threaded spindle sleeve combination LN being flanged to the motor axis and the other end to the underside of the support surface 100 AP of the rear cushion (cf. also FIG. 109). The motors are controlled by a circuit board arranged on the underside of the cushion support surface 100 AP (electronics E with ICs IC, cf. also FIG. 56a); The motors are attached to the lowered continuation 100 W of one of the two carriages of the front cushion (e.g. lower carriage 100 ).

For the variant of motor adjustment, two variants are distinguished, one in which the adjustment is made with the hand raised and the device with lower power motors and low weight, and a second variant, the engine power is sufficient to make an adjustment with the hand on. In both cases the threaded spindle sleeve combination LN self-locking.

In Fig. 77 is also indicated how the underside of the connecting surface of the contact surfaces 100 M, 100 N of the rear cushion and the front cushion at the point where the motors are mounted is further supported with a further sliding surface which is fastened to the front rail guide is. In addition, the support of the support surface 100 AP of the rear cushion is still possible (with 100 -UP in FIG. 87b) or by a further rail guide of the support surface of the rear cushion, as explained in relation to FIG. 97.

Another variant is the front pillow is equipped with a pressure sensor that measures the contact force of the placed hand, this being the case absolute, or relative to the contact force of the arm on rear cushion optionally via another pressure sensor can be done for the support of the rear pillow.

are sufficiently powerful motors for height adjustment used, then the automatic readjustment can a measured mean value of the hand's contact force on the other hand, are only small engines used, then the adjustment takes place in one separate process can be activated, e.g. B. if the User makes a height adjustment on his seat, because the distribution of the support forces of front and back pillow changes. Is the readjustment function  function is switched on and the measured average deviates the distribution of the contact force from its target value, then an acoustic signal sounds from a piezo signal generator, whereupon the user's hands from the pillows takes. After the pressure sensor detects this, begins motor level control with incremental adjustment, e.g. B. in approximation to binary weights (starting with the greatest weight) after a successive Apro maximization (corresponds to the well-known A / D converter Principle). For this weighted approximation step, the Users with the signal prompted hands again to lay on the pillows, or after the proximity measurement remove again, during the measurement period the user, for example, a sample text in the Keyboard can type. This comparison takes place as long as until the specified target value of the contact force is reached is.

The adjustment procedure is initiated e.g. B. with a Keystroke. The signal to ask hands on that Laying pillows, for example, corresponds to the rhythm a free tone signal (official tone) of a telephone, the Request to take your hands off the pillow again Busy tone. If the adjustment process is finished, then sounds z. B. a mixed signal (short-long, etc.).

A Another variant is a voice signal chip for the Install instructions.

Further details for the servo-related height adjustment of the rear cushion are described in FIG. 109.

An exemplary embodiment for measuring the contact pressure on the front cushion is shown in FIG. 76b and has already been described for this figure in the preceding part of the description. It is evident that this principle can also be applied to the back pillow as a supplement or alternative.

Fig. 78 shows a side view of the combination, and Fig. 69a and Fig. 77 with the areas of HA for the palmrest at or before the wrist and AA for the armrest past the wrist.

Fig. 79 shows an example of the attachment of the cables 45, 46 on the guide element 98 with contact entry from below (AZSU) to top (AZSO) to the slide plate. The cables are attached to the sleeve 98 S, which the pivot bearing for the guide member 98 inserted rotatably forms in 98 S of the lower slide plate 100, isolated attached (for. Example, by plugging together of two mutually insulated sleeve disks having therebetween respectively plugged fastening plate for the cables (incl Soldering lug for contacting); e.g. hooked into rings, results in contact through the opposite pulling force of the cable pulls (the differential force control of the right and left cable pulls).

Fig. 80 shows a side view (section) for the preferred embodiment using a replaceable plastic strip for the sliding surfaces, both for the top, as well as the underside of the rail guide surface. At the top, the strips 99 -O are placed on the support surface 99 of a frame 102 , which on the outside by the protruding edge strips 102 and on the inside by the axes of rotation (or guide elements 98 ) of the lower slide plates guided in the guide slot X, the lateral fixation for the strips 99 -O forms. A further additional fixation is provided by the preferred stop strips (ZPF, Fig. 81), which are inserted as end pieces (ZPF, Fig. 81) at the lateral ends of the sliding surface in the guide slot. Since the axis of rotation guided in the guide slot X (from 98 , cf. also 98 b in FIG. 79) in the absence of sliding support of the rear cushion (cf. alternatives shown above) on its underside, with the sliding plate 98 acting as a trigger protection on the underside of the Edge of the guide slot (cf. 99 -f in FIG. 79), the narrow strip, which relates to this process (on the underside) on both sides of the sliding plate 98 , is designed as an interchangeable sliding surface strip: 99 U in FIG. 80. For this purpose are the limiting webs, which support the edge of the guide slot on the inside 103 c, by the thickness of these sliding surface stiffeners, so that the lower sliding surface stiffeners 99 U from the side into the resulting slot between the top of the limiting webs and the underside of the support surface ( 99 ) can be inserted. This takes place through the slot (cf. B in FIG. 81), a side bar of the frame, which at the same time forms the insertion opening for the guide axis 98 of the slide 100 . The lateral fixation of the sliding strip 99 U inserted on the underside of the guide slot on the underside is carried out along the guide slot by the axes of rotation 98 of the slide plates guided in the guide slot and the end pieces inserted into the slot (ZPF, FIG. 81) and also by the adjacent, lower limiting webs 103 c put on further support webs for fixing the support strips 99 of the sliding surface 99 -O). An alternative to the lateral plug-in version of the exchangeable sliding strips is described in FIG. 110, in which the rail surface can be folded open in the longitudinal axis.

Furthermore, FIG. 80 illustrates measures for the expansion option, in which the guide element 98 of the axis of rotation of the lower slide presses against a capacitive length scale (cf. front description part), which can be carried out on the underside or on the top. The capacitive length scale (e.g. saw tooth pattern) is then applied directly to the underside of the interchangeable sliding surface in question (from 99 -O or 99 -U). B. can also be carried out by printing with a paste within a double film, and as an alternative to evaluating the capacitance (see advance notification), evaluating the ohmic resistance (measured via the capacitance of the guide element) can be carried out. F98. . . or 98 -GL are correspondingly electrically conductive washers and are pressed against the capacitive scale (insulated) by spring force. The detachable contacting of the capacitive scales on the exchangeable sliding surfaces of 99 -O or 99 -U takes place e.g. B. via eyelet contacts or capacitively over large contact areas (to contact surface 99 , which is contacted with a fixed connection).

The use of a capacitive Scale, its capacitance value or ohmic resistance value from an electrode of the Guide element of the slide plate each capacitive is short-circuited, whereby by stationary measurement of the short-circuited electrodes is the one driven Length of the sled is advantageous if the sled plates have no signal feed devices and have no traction ropes. (Alternative e.g. also optical scale). For cursor control (cf. preceding, it is sufficient if the pillow is for only one hand is scanned in the distance traveled).

If use is made of the pull rope variant using the trailing principle according to the invention, then the displacement path of the slide plates can also be tapped over the unwinded pull rope length for the purpose of cursor control (see advance notification) (see Fig. 45).

If required, the variant according to FIG. 79 can also be designed according to FIG. 80 with exchangeable sliding surfaces 99 -O and 100 U. Fig. 81 shows how the end pieces (ZPF) are inserted into the guide slot X at both ends of the rail guide (only one side shown). Preferably, the end piece (ZPF) designed as a short last piece for one side of the rail guide has a right-angled transverse bar LA at its outer end end, through which the end bar forms a T-piece, the attached transverse bar being inserted into the insertion slot B on the relevant side (Cross bar LA over length BZ according to Fig. 71c suitable for insertion slot B).

As a further special feature, the return path for the deflection of the cable 45 , 46 by means of a guide groove XRF is shown in FIG. 80 if use is made of this variant (cf. FIG. 88, FIG. 89, FIG. 90); 103 d. . . Rounding of the inside of the web of the guide slot X if cable pulls are used.

As shown in Fig. 81 and in the oblique view of Fig. 71c regarding the end strip, the transverse strip (LA) is set somewhat higher than it corresponds to the plug-in strip ZPF (ε... 99 -O = plane of the upper sliding surface strip); the bottom edge of the connector strip (ST- 102 B) is therefore supported on the side frame strip ( 102 B in Fig. 81).

The projecting shoulder of the T-piece (ST 99 -O) in turn forms the lateral hold of the sliding surface strip 99 -O.

For the other side of the rail is a simple short bar without a T-neck, as an end bar sufficient.

Fig. 82 shows the lower slide plate without cross slide guide part (cf. 99 B in Fig. 69a).

As a further special feature it is shown in Fig. 82 that the sliding pills (skids 101 , cf. also Fig. 82b) and the slide plate are inserted at an angle y which is dimensioned such that their stop on the flat side edge (SRND in Fig. 82b) of the pills on the protruding longitudinal bar of the slide frame (see bar 102 Fig. 69a), lies flat against the inner edge of the bar.

Fig. 83 and Fig. 76 illustrate the set on the lower carriage plate cross slide in the already explained above variants. As a further special feature, a fastening sleeve HUS is provided in FIG. 83 for the formation of the rotational axis 98 made of POM (with spacer S) sliding in the guide slot (cf. X in FIG. 97 of the sliding surface), which fastening the fastening of the Axis of rotation reinforced on the underside of the slide plate An alternative is to secure the upper fastening plate of the sliding element directly with screw fastening.

Furthermore, it is shown in Fig. 83 (below) how the relatively thin vertical pins (neck) of the guide elements 101 -OS, made of plastic POM), which are each closed off with a plate acting as a trigger protection, of the upper slide against lateral bending by sheet metal or other plastic plates (BLC1 and BLC2) are secured. For this purpose, such plates are screwed onto the underside of the upper slide 100 S, each of which has a slot SLC into which the neck ( 101 b, FIG. 83 below) of the guide sliding elements 101 -OS used as guide pins is inserted, the plate presses or covers the heads 101 -OS of the sliding elements recessed in the underside of the slide plate 100 S.

Fig. 84 illustrates how the sliding pills are inserted into the underside of the slide plate 100 and thus form skids ( 101 , same as 101 -GS for 100 S upper slide plate).

Fig. 85 shows the corresponding side view of Fig. 84, 101 -ES means the incised slot for inserting the pills 101 (shown in Fig. 83 as cross-hatching).

Fig. 86 shows the use of the device on an ergonomic keyboard with a curved front line, the strip of the sliding surface of the rail guide 99 -O including the guide slot X and frame 102 having a curve shape parallel thereto. SP. . . The space between the keyboard for the right and left hand enables an equivalent splitting of the rail into R. . . Part for right hand and L. . . Part for left H hand. The table edge TK is also shown in FIG. 86.

Fig. 88 shows an example with the splitting of the rail into two guide parts for right and left hand separately, which has the advantage that the bare traction cables of the sled plates from the right hand and left hand do not need an insulation bridge (in contrast, e.g. according to Fig . 90). As FIG. 88 shows, the front long side of the curved frame of the rail sliding surface partially projects above the table edge, the underside of the rail sliding surface being supported by clamps, such as are used as table cloth holder clamps 702 , or the clamps 702 ST in a further development an additional screw support is still modified (see Fig. 114 below).

Fig. 90 shows the variant with the 99 M insulation web provided for the traction cables, with the deflected traction cables being returned on both sides of the long sides of the rail frame (cf.XRF in Fig. 80) and the bare, live cables on both sides of the insulation web Cable pulls are running. The contacting of the cables for the feed takes place z. B. via attached to the conductive traction sheave contact springs, the contacting of the slide plates is described in Fig. 79.

Fig. 87a, b and c illustrate side views according to the previously described variants. KLT-702. . . Velcro or adhesive connection holds the underside of the rail guide to table bracket 702 . Also mean: KLT2 and KLT3 are Velcro or mushroom tape strips glued to the underside of the leather pad LD, which on the one hand adhere to the fleece band at the front edge of the uppermost slide of the front cushion 1 -V (KLT-2, see matching fleece strips KLT-2 top slide plate in Fig. 69a), on the other hand stick to the fleece surface of the rear cushion (KLT-3 at 1 -H), whereby by attaching several parallel Velcro strips (KLT3) the leather piece (LD) going from the front cushion to the rear cushion accordingly can be varied ( Fig. 87a), but as an alternative to this, separate pieces of leather can be used for the front and rear pillows (cf. LD2 in further figures). Due to the Velcro fastener, the leather cover variant for the front and rear pillow is easy to replace, in particular the variant for the support of the front pillow with a window 1 -FV with Velcro edging on the underside for improving the grip on the front granule cushion (see Fig. 9). Fig. 87b illustrates yet the variant in which the bearing surface of the rear pad 100 -AP via a joint (GLK, hinge with axis parallel to the keyboard front line) is coupled to the front cushion so that the rear cushion on the additional supporting surface 100 -UP sure slides.

Fig. 89 illustrates the deflection of the traction cables, which is always tensioned by counter-control of the drive rollers 48 , 49 , by means of deflection rollers 49 UR and 48 UR, which is particularly suitable for a split keyboard (see FIG. 97) (see the previous description) or also for an embodiment according to FIG. 90.

K1S and K2S are sliding contacts or spring washers, which carry out the signal feed on the bare pulling cables 45 and 46 on the electrically conductive winding reels or their axes. The uncoiled pull rope length can also be measured, for example, via the damping measurement of a coil spring inductance, which lies against an insulated metal disc, as already explained in the front part of the description.

Fig. 97 shows an oblique view of the entire device with separate sliding surface for the front and back cushion, said rear cushion behind something is high in support of Wippwalze of only partially filled cushion 1 -H (bar HSL). Leather piece LD2 of the front pillow 1 -V has a window through which the granulate pillow filled in foil protrudes, adheres to the window edge on the underside of the leather pad with Velcro strips (shown hatched); LD2 is separate from leather LD of the rear pillow; or continuously connected LD2 to LD).

Fig. 91a with Fig. 91b and Fig. 91c illustrate preferred variants for the tilt-proof fastening of the rail guide strip ( 99 with frame 102 ) immediately above the table edge (TK). The variants have the following function in common: the usual tablecloth clips used as retaining clips ( 702 e.g. made of transparent plastic or steel sheet clip 702 ST according to Fig. 114) hold firmly on the attached table edge, but would be unstable against lateral twisting. It is therefore provided that the underside of the rail guide strip is provided with rubber feet GF, which press firmly onto the table top by pressing the upper clamp part 702 -O of the holding clamp 702 , 702 ST. Due to the further measure of a guide bar 704 on both sides for the upper clamp part 702- O within the rail guide strip , the clamp is secured against lateral rotation and good adhesion of the rail guide strip is ensured with quick disassembly. Furthermore, the adhesion of the rail guide strip can be increased by means of removable adhesive (cf. FIG. 113) or improved by screw clamps (cf. FIG. 114).

Fig. 91c shows a variant in which the upper clamp part 702- O is attached to the outside on the underside of the rail guide strip 103 , with side guides or webs (PF), which can also form the pressure surface made of rubber (GF), for example .

Fig. 91a with Fig. 91b, on the other hand, illustrate a variant in which the upper clamp part is inserted into a slot 102 -F, which is provided on the longitudinal part of the rail guide strip 102 at corresponding intervals, and presses on the upper side on the bottom side of the rail guide strip, whereby Fig. 91a shows a top view from Fig. 91b below, with section SC-SD; and FIG. 91b below shows a side view with section SA-SB from FIG. 91a. Fig. 91b above, shows a side view of Fig. 91b on the right, which in turn represents a section through the table edge TK for both variants (cf. option of 702 , 702- O).

Preferably, the recessed into the longitudinal side 102 insertion slots 102 F are arranged such that the underside of the upper clamp member 702 -O rail guide strip rests on the upper surface of the bottom 103, as shown in Fig. 91b below the ridges 103 b and 103 c , see. , are sized in height so to Fig. 80 which carry the support for the Schienengleitauflage 99 that still a gap (ZWI) is formed above the upper clamp part which is sufficient to lower Gleitflächenstreifen 99 U even higher to push, in which the Places where the clips are to be inserted into the insertion slots, the webs have interruptions, and to facilitate the insertion of the clips, are provided with lateral transverse guide bars 704 in the direction of insertion of the clips (transverse to the longitudinal direction of the rail guide).

Another preferred measure is to provide the underside of the rail sliding support 99 piece by piece over the insertion points of the brackets, which fill the space (ZWI) above the upper bracket part to such an extent that the upper bracket part is firmly constrained in the insertion slot on the one hand from the top, on the other hand, the space is provided outside of this pressure area in order to insert the narrow strips of the lower sliding surface 99 U on both sides of the guide slot X; (cf. inner boundary lines of the lower sliding surfaces in FIG. 91a, within slot X, the lower sliding strips 99 U not being shown in FIG. 91a (shown as drawn out).

FIG. 92 illustrates how the framed 102 Schienengleitauflage is inserted 99 -ADPT in another frame 99 (eg., Via Velcro adhesion or pressed by brackets), which like the Schienengleitauflage, but constructed without the guide slot, and the increase of the cushion device for TK is used on typewriters. . . Edge of the table).

Fig. 93 illustrates an example in which the lower slide plate 100 is glued with Velcro strips for placement on the surfaces adhering to the Velcro strips, at the ends of which the stops 705 or 703, which can be removed via these surfaces, for inserting the upper slide plate into the rail guide 99B are provided.

Fig. 94 shows a variant in which rollers RL are used instead of sliding surfaces, which enclose the sliding surface or rolling surface (corresponds to 99 ) like a sandwich (secured against rotation by parallel connecting webs 98 ), KGL a ball bearing for the possibility of rotation of the slide plate is.

FIG. 95a with 95b shows a circuit proposal for the two-pole (K1S / K2S) Signal transmission via the lift cords 45/46, wherein the electronics further distributed on the slide plate as required, and by continuing the two-pole cable bus bar several participants of the stationary transmitting center ( S housed in housing 54 in Fig. 88) can be interconnected.

The circuit of the participants corresponds to FIG. 95b, each with a microcontroller μP-E, which sends or receives a serial data signal DAT (eg modulo 2 signal) in bidirectional direction (SE / EP) and furthermore the voltage supply of the participants from the received one serial power data signal is fed (rectifier D with capacitor CS), this supply of the supply voltage being switched off during a return operation of the receiver (via S, electronic switch), as a result of which excessive stress on the receiver supply is avoided. The receiver circuit is supplied with a power data signal only by the fixed transmitter S, the voltage VCC rectified in the receiver E being fed to the electronics as a supply voltage via a step-down regulator or converter, and the (higher) voltage of the power data signal being buffered in a storage capacitor CS .

Furthermore decreed the receiver circuit via a watchdog timer circuit for time monitoring of the data signal, with an exposure of the transmitter circuit (recognized by Time interval detection in µP), the receiver circuit in specified times according to the protocol to the Return the fixed transmitter circuit if you have previously have been addressed. Dates and addresses are inside of the serial data ordered according to a mandatory sequence.

OSZ feeds the sensor coils, the damped vibration is in a VCO (voltage-dependent oscillator circuit) fed whose frequency by a microcontroller circuit is evaluated (see front part of the description).

The damping measurement for different displacement measuring points, Weight measurements, height adjustments, point one parallel resonance circuit each for each oscillator circuit different frequency on what a causes sufficient decoupling of the measuring systems.

Other variants are:

The top slide of the front pillow with its direction of movement between User and keyboard front (transverse to the longitudinal direction of the Keyboard), also with a motorized cable drive Mistake:

This variant is further illustrated in FIG. 93 with the two drive motors M1 and M2 (set lower behind the slide plate, after a distance of 100 V, see FIG. 97 ) and FIG. 78, wherein the drive motors can contain further subscriber circuits according to FIG. 95 and the Bus circuit via the other cables of these drives is continued. The control for the height adjustment of the rear cushion (see M5, described above) including the sensor circuits can also be included in the bus circuit.

The cable deflection takes place with the pulleys UL1, UL2 and ULV, cf. Fig. 78: first cable pull over the ULV deflection pulley pulls the carriage 100 S forward with deflection of the rear pulley UL2 (see Fig. 93) and another cable pull over another rear deflection pulley UL1 pulls the carriage back, with both cable pulls each pushing from M1 or M2 are driven, equivalent to the principle already explained according to FIG. 89. In FIG. 93, UL1 is driven by M2 and UL2 by M1, each via horizontally mounted axes.

The sensor department for the drive in the further coordinate direction then takes place with the embodiment according to FIG. 76b, the frame RM not only having a play (VSP) in the lateral direction to a lateral stop surface (rail guide), but also in the front (towards the keyboard front) and at the rear (towards the user) with a corresponding coding of the frame sides by plates 33 and associated scanning coils E on the lower slide plate.

All drives are in soundproof housings housed, the pulling ropes via interchangeable insulated cuffs, e.g. B. pressed into sleeve (with rope inserted in the side slot) with screw thread for a corresponding housing bore from the Housing are out.

Fig. 96 shows a variant in which the frame RM does not slide on sliding elements, but in a ball groove (KGLn) (with lateral movement play VSP).

In the lateral direction, the ball acts as a sliding element, whereby the underside of 100 S is the sliding surface (optionally exchangeable via sliding strips); in the direction of the keyboard front, however, the rolling function of the balls is given, the balls can e.g. B. also be made of POM (see above).

Fig. 98b through FIG. 105 show exemplary embodiments of a retractable cord function when the slide plates are to be temporarily supplied with signals for the purpose of the adjustment of motor height adjustment of the back cushion, and no cables for a further servo control, or no supply rails for carrying signals, provided are.

Fig. 103 and Fig. 108 illustrate circuit measures to carry switching signals for this simplified version via a two-pole cable and, with the least possible switching effort, voltage settings of an operating element (switch or potentiometer) attached to the frame of the sliding surface, the microcontroller for those on the slide plate notify housed electronics (IC, from E in Fig. 77) for the height adjustment of the rear cushion. The control element is used to specify which contact pressure for the front cushion is to be specified as the desired value by adjusting the height of the rear cushion. B. 3 switch positions (hard, medium, soft... Strong (H), medium (M), weak (S)) are sufficient.

Fig. 104 shows the variant in which a two-pole cable can be pulled out against a return spring on both ends of the frame 102 B, the end of the cable each having a two-pole jack plug 907 as a connection, for direct insertion into suitable sockets (cf. 901 ) of the slide plates (see Fig. 69a) on the outside.

The cable routing for each of the two cables is formed in each case by a metal tube (Rab in Fig. 105), the first contact pole of which is the inside of the tube and the second contact pole of which is a busbar 906 e inserted into the tube (and 906 d insulated from the tube) is. A mini slide 906 c slides in the cavity between the inside of the pipe (Rab) and busbar 906 e, supported by a pair of contact springs, of which one contact 906 b rubs against bus bar 906 e and the other contact 906 a bears against the inside wall of the pipe.

The mini slide is centered by means of a disk segment 904 , which is held over sheet metal brackets 906 aK and which is slidably guided in the hollow space of the tube (between the inner wall and the busbar). The double-core connection cable (a, bL) is inserted through a through hole on the front side of the disk segment 904 and fastened to the metal bracket 906 aK, which is designed as a strain relief piece (via a pair of holes with a pulled cable), with one wire of the cable at the contact poles of the Sliding contacts 906 a and 906 b of the mini slide 906 c clamped or soldered. A magnet 904 is attached to the pulling side of the disk segment , which magnetically adheres to the end of the tube which is closed except for the through hole of the cable (RST, see FIG. 99) as a stop after the cable has been pulled out. A rubber cord (GBR) is used as the return spring of the cable, which is attached to the opposite pulling side of the mini slide. The trigger for the automatic cable retraction by the return spring (GBR) is triggered by pulling a rod ( 911 , Fig. 99) which, as an extension of the rubber cord, is guided in a guide hole 910 on the side of the sliding surface frame 102 B opposite the pulled cable and to which the rubber cord is attached (e.g. via nuts 912 , the rod having a corresponding thread attachment). The other end of the rod protrudes from the sliding surface frame 102 B and has a corresponding button ( 902 aL in Fig. 99) for pulling out. (The pulled-out position is shown in broken lines). The length of the rubber cord (GBR) is dimensioned such that after a certain pull length by pulling out the rod 911 , the rubber cord (GBR) is fully tensioned and no longer stretchable, as a result of which the pulling path of the rod continues directly onto the cable fastening of the disk segment 904 and its magnetic adhesion on the face of the tube breaks, whereby the rubber cord returns the cable into the tube guide by means of the mini slide 906 c, same as the pulled-out rod. The minimum tension of the rubber cord (GBR) is dimensioned such that the rubber cord is still tensioned when the rod is inserted and the cable 909 L for the left side and -R for the right side inserted.

As shown in Fig. 98, the plug contact terminal of the cable has a respective end plate 909 b on which rests the cable to the Einziehloch 909.

Fig. 98, Fig. 99, Fig. 100 Fig. 101 (contact tap 906), FIG. 102 (as a screw jack parts 905 a and 905 b running cable centering) illustrate a further alternative using in each case a separate tube for each terminal post, where in the reference designations (R) and (L) for the right and left side (or a and b) for the cable wires, the two-pole connections a and b are used.

In Fig. 104, two operating elements are arranged opposite one another on opposite sides of the frame for the sliding surface 102 B: on one side a button TN, on the other side a toggle switch 908 S with 3 positions (or alternatively a potentiometer) for specifying a reference voltage, which corresponds to a predetermined contact pressure for the front cushion for the described adjustment of the height adjustment of the rear cushion. The circuit for this is shown in Fig. 103: The supply voltage (e.g. supplied by a mains plug power supply unit N, plugged into the frame of the sliding surface via the connector STK102 on the side of the longitudinal bar 102 ) is fed to the control electronics in two poles, this feed being carried out by the button TN (as Normally closed contact) can be interrupted at the push of a button. Furthermore, the supply voltage can be varied by the control element and selected so that it is in all variations above the value of the actual supply voltage (eg switchable by means of a zener diode circuit).

The circuit shown in Fig. 103 is housed on a small circuit board below the sliding surface support (in frame 102 ), the cable guide tubes for right and left cables 909 L and 909 R being connected to the outputs of the circuit accordingly (bL, bR in parallel for left and right cable, same as aL, aR = GND for right and left cable, see also option according to Fig. 100 for interconnection if wires are routed in single-pole cables).

Fig. 106: see Fig. 112, below.

Fig. 107 shows the use of the cushion device on a multi-dimensionally curved keyboard 8 : The support surface 99 for the sliding support of the front cushion 1 -V is placed on the keyboard already integrated sloping hand support strip in front of the keypad, via a soft pad 930 , on which the Appropriate adapted metal clips ( 929 with bending edges 929 B) are placed on the respective width and inclination of the handrest strip, the underside of the metal clips being inserted piece by piece on a support surface 103 which is placed under the keyboard (e.g. as a sandwich), the inclination and The width of the hand rest strip can change over the length of the keyboard.

The side profile of the sliding support is designed such that converge on the longitudinal side, which is the row of keys closest to the sliding surface and underside of the rail guide frame 930 pointed.

Fig. 108 shows the electronic circuit housed under the support plates of the rear cushion 1 -H with a piezo signal transmitter or loudspeaker: The supply voltage set with toggle switch 908 S or a potentiometer (wire bL for left slide plate or wire bR for right slide plate, respectively inserted in socket 901 , see Fig. 69a) is fed via a voltage divider to a VCO (voltage controlled oscillator), the frequency of which is evaluated by a microcontroller in such a way that a reference value for the permissible weight load of the front cushion is set which is associated with the voltage value.

The reset line of the microcontroller is also connected to this voltage and generates a reset vector for each voltage interruption by pressing the TN button ( Fig. 103) when the voltage of the microcontroller has returned (delayed via RC circuit, with discharge diodes for quick readiness, or alternatively also by external pulse generation chip). In the microprocessor program, the reset vector initiates the adjustment method already described above for performing a successive appromaximation. OUT / IN are corresponding I / O ports signal lines of the microcontroller, BW (a, b) relates to an evaluation circuit for damping measurement of the scale for each slide plate (cf. L6 with metal spring plate 633 in the figure); the loudspeaker or signal transmitter connection of the microcontroller is not shown.

Fig. 109 shows a further exemplary embodiment for the motorized height adjustment of the rear cushion 1 -H, an additional guide between the plate of the front cushion 100 V (cf. also with bevel 100 M) and the plate of the rear cushion 100 AP also being omitted and can be formed directly by the spindle of the motor drive. Fig. 109 shows a corresponding embodiment with a pair of vertically standing threaded sleeves 916 , which are flanged to the motor drives (M5a, M5b) and in each of which a bolt is screwed into the internal thread, which supports the support plate of the rear cushion 100 AP ( screwed tight with nuts 917 ). (Left: view seen by user, right: associated side view). The motors rotate in opposite directions; the spindles have correspondingly common threads.

Furthermore, the threaded sleeves are supported directly along the vertical wall of the lowering of the front carriage plate 100 W, the support being provided by cable clamps (or ties) which are fastened to the wall 100 W and the sleeves are rotatably guided within the clamps. In order to bring the motor axis close to the wall 100 W, a punch is provided on the wall, in which the motors are inserted (supported on support plate 918 ); the continuous motor axis is also supported by a sheet metal spring 999 on the underside of the motor mounting.

The threaded sleeves 916 are preferably made of electrically non-conductive material, but the screwed-in threaded spindles (threaded rods 915 ) are made of metal. Furthermore, at the point that affects the screwed end of the threaded spindles, a coil (inductance 913 ) is placed over the sleeve (inserted in wall 100 W in a window), which depends on the screwed end of the threaded spindle respective screw-in depth is damped according to the respective height position of the bed plate 100 AP of the rear cushion. The damping measurement of the immersion depth of the threaded spindles regulates the synchronous operation of the two motors M5a and M5b, which drive the support, and measures the height adjustment in binary weights (see above). In Fig. 109 and Fig. 77 there is also the two-wire connection cable (VKBL) present between the contact surfaces of the front and rear pillow for connecting the electronic components (e.g. L6 in Fig. 80) accommodated on the front pillow support Printed circuit board (E) under 100 AP.

Fig. 110 shows a variant for the insertion of the lower strip of the slide surface, see FIG. in addition 99 U in Fig. 80 and Fig. 81 (described above). This variant is well suited for curved shapes of the guide slot X, because then the lower sliding surface strips can no longer be easily inserted from the side: For this purpose, there are corresponding points of curvature that are in an alignment line (m) below the guide slot X. , on the bottom underside 103 of the rail support hinge joints (MGL) are provided, which allow the bottom underside to be folded down on both sides of the guide slot (with the underside lifted off from a support surface, the underside 103 being placed on a further support surface, for example via a Velcro fastener connection) ). This creates an insert opening on the top, into which the curved strips of the lower sliding surfaces 99 U (cf. FIG. 80) can be inserted on the support webs provided for this purpose (ST- 99 U, hatched).

Fig. 114 uses a steel bracket 702 ST with as little spring as possible as the table bracket, the bracket pressing the rubber feet GF attached to the pressing points of the bracket on the underside of the rail support 102 against the table top and the lower bracket part a fixing screw 500 pointing upwards towards the underside of the table to generate the pressure force and presses via a plate or an intermediate layer PLT between the screw end and the underside of the table top. In this variant, too, the lateral rotation of the clamp 702 ST is provided by the interaction of the crossbars 704 described as FIG. 91a (as a guide) and the rubber feet of the rail support 102 adhering to the table top, the clamp being easy to mount (because in guide slots 102 -F Fig. 92, Fig. 91 of the longitudinal strips 102 ) and is to be dismantled again.

Fig. 115 shows a variant in which an extending AFL on which the keyboard is placed 8, the underside of the slide guide 102 presses on a planar extension DT at the front side of the keyboard, and thus the slide guide 102 to the table top (along with staple 702 ) presses.

Fig. 116 to Fig. 119 relate to further variants of the zero-force compensation by the tracking control. Fig. 119 (top) shows a variant for the single-line longitudinal guidance of the slide plate 100 , in which the guide element is designed similarly to Fig. 79, with a disk 98 S acting as a bearing sleeve or bushing, one in the hole of the disk inserted bolt ( 98 b as a guide element, runs in slot X), which has a through hole for pushing through a cable connection (AZSU, led from bottom to top, contact ... K2SR), with the difference, however, that the bolt continues to 98 b a drive wheel 98 WKL is flanged, with which the angular rotation of the cushion is made via the rotation of the guide element (= bolt 98 b), and instead of the cables pulling on both sides of the bearing sleeve 98 S as in FIG. 79, this only for one Tension side is made on the bearing sleeve 98 S and for the other tension side a pair of cables is provided, which is looped (or laid) over the drive wheel (within a raceway), ie on the drive brad attacks. By controlling the lengths of the cables 45 R, 46 R (cf. Fig. 119, section AB below) of the cable pair placed over the drive wheel 98 WKL, the rotation v of the drive wheel or of the guide element 98 b is carried out, the on the Bearing sleeve 98 S holds (single) cable pull (or double cable A 45 H 46 R + B 45 H 46 R) against it in the other direction, on the other hand by further differential control of this (single) cable pull (or double cable) against unwinding or unwinding the pulling cables of the pair of cable pulls on the drive wheel, the longitudinal displacement of the guide element (in the case of mutually tensioned cable pulls). In the figures Fig. 116 to Fig. 119 mean: 45 R, 46 R. . . Cable pair of the drive wheel for the slide plate of the right pillow, same as 45 L, 46 L for the left pillow; 45 H 46 R. . . Cable pull of the bearing sleeve 98 S for the guide element of the right pillow, same as 45 H 46 L for the left pillow, whereby two variants are provided for the cable pull attached to the bearing sleeve 98 S:

In the first variant, the differential control of the cable pulls of the cable pull pair attached to the drive wheel is carried out directly by the drives which pull the individual cable pulls of the cable pull pair for the purpose of the longitudinal movement of the guide element; therefore, for each of the two cable pulls of the cable pull pair assigned to the drive wheel, there is a winding roller with drive provided (see six drive rollers in Fig. 117). In the second variant, a common winding by common drive is provided for the incoming cable length, as for the returning cable length, according to the principle of a winding roll, as z. B. for the transport of printheads on typewriters and printers is standard, the length of cable that is unwound on the winding roller of the incoming cable corresponds to that of the rewound that is wound up. In order to enable this principle even in the given version in connection with the drive wheel rotation, the incoming cable pull z. B. the pair of cables on the drive pulley and the returned cable corresponds to the cable on the bearing sleeve (disc 98 S), the cable on the bearing sleeve 98 S (see also 45 H 46 R in Fig. 117) is also a double cable (A 45 H 46 R + B 45 H 46 R, see Fig. 119), but without differentiated train length control, but with parallel processing of the same cable lengths for the cables of the double cable. In Fig. 117 the option for the redirection OP of a double cable with paired pulleys UR + OP is also shown (cables shown in dashed lines). The separating web (XM, Fig. 119) for separating the cables attached to the drive wheel is then broken through at the points where the cables are deflected (at the ends of the guide lines of the right and left cushions); Guide slot X is shown in broken lines in FIG. 117. Due to the separating web XM, the following structure results for the guide element: a pin or bolt inserted into the guide slot X from above with a drive wheel flanged underneath and the drive wheel bearing underneath in a corresponding bushing or perforated disk.

In a preferred embodiment, a drive (ML, MR for left and right pillow in Fig. 118a) is provided for the guide element of each cushion, the drive shaft of which each has a pair of co-driven winding rollers (cf. A-roller and B-roller on a common axis attached or coupled via belt drive, in Fig. 118a), on the two winding rollers of a drive, each of which (see A-roll and B-roll in Fig. 118a) is assigned to a cable pull pair of the cushion relating to the drive, A cable pull from the pair of cable pulls (double cable pull) of the bearing sleeve is wound as a running cable pull and a cable pull from the cable pull pair of the drive wheel is wound as a return cable pull and the cable pulls of each cable pull pair are rinsed synchronously by the common drive of the two winding rollers. If the cable lengths that are guided and returned to the guide element for each pair of cable lengths, each consisting of a cable of the drive wheel and a cable of the drive wheel bearing (bearing sleeve 98 S), are wound and driven on a common winding reel, then the differential control of the cable influence on the cable pair of the drive wheel takes place additionally pressure rollers provided for the winding rollers, which are actuated by an electric motor or electromagnetically, this being done via each rope of the pair of cable pulls by a pressure roller with a separate drive (electrically controlled differential control) or by a common drive with mechanical coupling of the pressure rollers (mechanical differential control). 116,119 further details are given below to Fig through FIG explained.:. The variant of Figure 119 relates to an embodiment in which the attached to the bearing sleeve rope as a double cable (A 45 H 46 R and A 45 H 46 L) is carried out with associated. Drives ML (for left pillow) and MR (for right pillow) according to FIG. 118a; the lifting magnets with the pressure rollers DR perform an electrically controlled differential control (HMGLa and HMGLb for the left, or HMGRa and HMGRb for the right cushion) with the detail HMG shown in Fig. 118c (below) for the pressure rollers, the lifting magnets HMGLb and HMGRb can be omitted if a mechanical differential control is carried out, such as. As shown in FIG. 116a, with pressure rollers DR mounted on a common bearing bracket (cf. sheet metal FIG. 116b), which press the cable pulls on both sides of the cable pulls concerned within variable slack loops (supported against support rollers SR) by joint displacement of the pressure rollers, or shift the slack asymmetrically, starting from a symmetrical slack for both cables, so that the slack of one of the two cables increases and that of the other decreases, corresponding to the motor-driven displacement of the pressure rollers. The asymmetrical displacement of the slack then causes a corresponding rotation of the slide plate 100 via the guide element bolt 98 b, to which the cable pull pair in question is flanged (corresponding to FIG. 119). In a simplified version, it is sufficient to control the sag only on one cable pull of the pair of cable pulls (however, with the same roller dimensions, this only results in half the angle of rotation control for the cushion). In addition to the possibility of shifting the pressure rollers by means of a lever driven by an electric motor (see lever attachment AP in FIGS . 116a and 116b) or of using a solenoid, it is preferred that the shifting is carried out by means of a plunger coil (e.g. in accordance with conventional loudspeaker production) , on which a lifting rod (with AP) is flanged to control the displacement of the pressure rollers. Fig. 116c shows a proposal for a spring-tension suspension of the motor drive (M together with drive rollers hidden behind sheet metal, cf. A-roller and B-roller in Fig. 118a), ABL being a side plate of a sheet metal frame in which Slot guide LS on opposite side plates in the slot engaging pins of another inserted sheet frame (INBL) are slidably inserted and the inner sheet frame (e.g. over the pins) against the outer (ABL) by tension springs in one direction against the pulling direction of the pull cables (cf. 45 R to B 45 H 46 R; R stands for right, ditto L ... for left in other figures) is prestressed along the elongated hole guide, the inner frame (INBL) being the chassis for fastening the drive M in question Cable pulls are used for a pillow side. In Fig. 117 the option is drawn in, in which all the cable pulls are wound on reel spools (e.g. pretensioned in a rest position by spiral spring force), whereby instead of the six drives these can also be replaced by the arrangement according to Fig. 118a; SP. . . Line separating the area of movement of the right and left pillows. For the drives according to Fig. 117 z. For example, the inductance of the cable that is being wound up can be measured directly by tapping rollers (URLM, over its axis) and the winding rollers relating to the axis, for the variant according to FIG. 118a, the coupling of a tachometer generator (or optical disk) to each of the two drive motors and / or damping measurement 45 preferred according to the transducer of FIG . The regulated stroke length of the solenoids is z. B. measured via their inductance or only via the sensory measurement of the cushion twist (see diagonally opposite measuring points of the cushion guide for the transverse direction shift in the previous part of the description) measured and transmitted via the cable contact (from the slide plate of the cushion to the motor control). For the exemplary embodiment according to FIG. 119, the cable contact is made on the guide element for a contact point (K2SR) by isolating the disc acting as a bearing sleeve and a 98 BS fastening pin inserted into the disc (in each case) for fastening the cable (or double cable) with appropriate implementation of the cable contact to the slide plate upwards (K2SR) and the further measure that the bare cable pair, which is placed around the drive wheel, forms a contact with the electrically conductive drive wheel, which is continued (contacted) via the axis of the drive wheel 98 b to the slide plate (with solder connection K1SR). So that the two cables of the double cable attached to the bearing sleeve do not get tangled, a separating web (XM) is provided, which runs along the center line of the guide slot of the longitudinal guide line of the sliding ruler and is placed on the bottom side of the sliding ruler and its height is dimensioned accordingly that, on the one hand, the cables pulled lower on both sides of the separating web XM by the fastening pins 98 BS are separated by the separating web and, on the other hand, the disc, which forms the bearing sleeve 98 S drawn by the cables, of the guide element can still slide well over the web XM without to put on the dock. In Fig. 119 is also shown (below): Section CD (bottom center) relates to the insulated bearing washer for the axis of rotation of the drive wheel, which at the same time forms the guide pin 98 b (slides in guide groove X); Section AB concerns the immediate top view of the drive wheel with optional mudguards (ZBL) to prevent the cable from slipping out when e.g. B. the tension spring bracket (SPF) of the drive (see Fig. 116c) is loosened (assembly aid). Fig. 117 relates to the special case that the drives for both pillow sides are made on the left side in order to keep the sliding ruler of the pillows free on the right. As a result, the redirections (UR) shown are required. If the guide line (or slot X) has radii, then rollers or rollers are provided at the corresponding points of curvature on both sides of the guide slot in order to steer the cable pulls in accordance with the curvatures. Fig. 118a shows a suitable housing for the cover of the drives and control electronics, which is preferably transparent and is placed on a base plate which extends over the entire length of the sliding ruler; SECTION . . . concerns the required distance for the freedom of movement of the left arm and can still be used to accommodate a control panel (e.g. capacitive keypad, etc.). Fig. 118c relates to Detail KG, a proposal for centering the pull cables over spring-loaded balls KG with ZS. . . Traction ropes, in addition or as an alternative to a centering guide of the traction ropes carried out by means of rollers. Other special features are: The use of the pressure sensing (scale) explained in the previous part of the description for measuring the hand or arm rest pressure continues to be used in such a way that the readjustment of the cushion movement by the motor drive is only activated when the hand or the Poor, because otherwise the control loop would be open. In a further development option, in the case of a sensory statement that the hand or arm is not resting on the pillow, the control does not switch off but on a further sensor, which in addition to the displacement movement detection of the pillow (see sensor in the game VSP or vector pressure sensor in the preceding Part of the description) is still available and the position of the hand and / or arm posture is also sensory if the hand or arm is not placed on the corresponding pillow and this sensory position indicator is used to continue the regulation of the caster post-run control is. Depending on the type of sensor used (optical, inductive or capacitive using sheet metal electrodes), the sensor is attached to the front or rear cushion. Fig. 97 shows an example of the back pillow, e.g. B. on both sides of the pillow support surface 100 AP laterally PS and / or rear (PSH at the corners of the rear edge of the support surface) optical reflection meters are attached, which scan the contours of the applied arm, z. B. the front and rear pillows are each fitted with a sensor for generating a hand or arm signal or not, and are designed with a sensor-controlled displacement play VSP and, in addition to a large number of possible combinations for the control, the following variant is preferred:

• a) the palm rest on the front pillow is sensory confirmed, then the cushion movement is regulated of the front pillow self-sufficient after the sensor inside the displacement play VSP of the front pillow as well the cushion movement of the rear is regulated Pillow self-sufficient after the sensor inside the  Back cushion displacement game VSP,
• b) the palm rest on the front pillow is sensory not confirmed and is the armrest on the back Pillow still confirmed, then the settlement of the Pillow movement of the front pillow and the rear pillow Pillow after the sensor within the sliding play VSP of the back pillow,
• c) is the palm rest on the front pillow as well as the Armrest on the rear pillow is not sensory confirmed, the sensor switches over on back cushion on the contour scanning of the applied arms and regulation of front pillow and back pillow after this contour scan so that the sensory scanning of the arm contour always lies within the contour limitation of the scanning, so follow the cushions in question with the arm position. This is done, for example, so that the rear edge of the sled plate on both sides arranged reflection meter at a distance are arranged, which is so dimensioned (and e.g. with Velcro connection made still adjustable) is that both reflectometers are reflected by the arm, when the arm is centered through the hollow of the air cushion is. If this is no longer the case, then it shifts the arm compared to the reflective knife so that on relevant limit range the relevant reflectance meter no longer reflects the arm, which is in relation to the another reflection meter (relative movement) one Asymmetry results by appropriate Movement control of the pillow is balanced, whereby the pillow follows the moving arm. It is evident that capacitive instead of optical sensors Sensors or inductive sensors this relative evaluation can make.

In addition to this option, a contour scan of the hand can of course also be carried out for the front pillow, with the self-sufficient control of the front pillow. An embodiment variant with a control method according to steps a, b and c above contains the following electronic components: for each front cushion, a small circuit board with four parallel resonance oscillators for four scanning coils for measuring damping over metal corners at the corners of the sliding frame of the cushion support described in the previous part of the description (with Game VSP), an oscillator for measuring the contact force on the corresponding spring plate and a microprocessor circuit for evaluation and transmission of the measurement signal to the tapped two connections of the guide element of the lower slide plate (cf. also Fig. 95a and Fig. 95b). The sled plate of the rear cushion has identical components. The control electronics, which are separated from the slide plates and fed with sensor signals via the traction ropes, contain, in addition to the reception and evaluation electronics and control circuit control of the drives, the control described above for level adjustment between the front and rear cushions, which in this version is not directly between the contact surfaces ( see M5a and M5b in Fig. 109), but via spindle adjustment of the level between the front ( 99 ) and the rear ( 99 H, see Fig. 97) sliding ruler (see also, e.g. also on a vertical guide wall (ie 704 in Fig. 87c corresponds to 100 W in Fig. 109), with two or more of the described sleeve-threaded spindle combinations connecting the two sliding rulers on their vertical or inclined sliding wall (cf. 100 W) at an appropriate support distance from one another motorized longitudinal displacement of the rear cushion (armrest behind the wrist) one way to create a table that has an ergonomic hand posture, such as the one described in B. already enable progressive keyboards (cf. keyboard from Microsoft... Registered trademark), make a suitable path control of the rear cushion as a function of the displacement and / or rotation of the front cushion according to an electronically stored function. Identical sliding rulers with identical drives can be used for both the front handrest pillow and the rear armrest pillow, whereby the relative height of the two sliding rulers can be adjusted by means of the spindle control described (see also the previous part of the description). Another variant is to also use the rotation detection of the pillow as an input function, e.g. B. in the following application: In a simplified version, the incremental pulse generation when the cushion is shifted (e.g. to control the cursor functions) is coupled to the hand rest of the other cushion, i.e. if the hand is lifted from the other cushion, the incremental pulse generation is prevented, so that Cushions in front of each pulse chain can be brought into a desired starting position. An alternative to this is to generate a short rotary movement with the other cushion before pushing the cushion on and to decode it accordingly, in which case the following sequence of incremental impulses generated by shifting the corresponding cushion is not evaluated, and the evaluation after a certain ( retriggerable monostable) trigger time of the pulses is switched back again. Advantages of the invention: The basic solution variant according to claim 1 already has the advantage that the cushion cover is inexpensive to manufacture, has the best sliding and movement properties and adapts to the hand position when typing; and, above all, in a wide variety of expansion stages, from a particularly cost-effective version to particularly demanding designs.

In summary, the invention thus relates to a cushion for a hand rest for typing keyboards, which has a support cushion sliding on a sliding surface for each hand (in an optional further development with an identical sliding and guiding point), with the following optional features:
Skaterunner (glide-skid-movement) storage of the cushions adapted to the movement of the hand during the typing process by means of small, separate sliding surfaces
exact height adjustment of the cushion for the palm rest with floating granules,
Pressure relief of the placed hand by another integrated wrist movement-optimized armrest,
Relief of pressure by converting potential energy into kinetic energy, in particular by using a rocker cushion for the rear cushion,
due to the interchangeability of the sliding surfaces for the rail guide, the sliding strips are easy to grow,
Rail guidance can be designed in a multi-dimensional curve for any ergonomics of the keyboard,
electronic measurement of the target contact pressure of the hand (also while writing) and automated adjustment for level compensation between the hand support cushion and the armrest, which means that the optimal conditions are always electronically determined before the user determines this too late through long-term writing in the event of any incorrect adjustment (electronic sensitization fulfills one Health monitoring function of the product),
Movement amplifier by means of a zero-force servo control of the cushion movement with sensor scanning of the hand movement during typing, by corresponding movement scanning of the cushion movement, e.g. B. by path sensing (movement play) of the cushion movement or pressure sensing, or both (z. B. via spring travel or inductive scanning with metal mesh provided flexible bands)
Problem-free signal feed, cheap version with integrated cable pull-in and various combinations of design variants according to user needs,
best possible adaptation to modern ergonomic keyboard shapes,
quick assembly and disassembly thanks to quick release,
Small space requirement, since the majority of the area for the cushion cover is outside the table top.
