Description

The invention is concerned with a further development and improvement of a scissors arrangement, as in EP 1 223 287 A2 is explained, cf. in particular page 1, paragraphs [02] and [03]. Apply the scissors to an attachment on the edge of a wing to allow in addition to a raising movement of the wing and an engagement movement in a driver pin within the rebate, which engaging movement dissolves when the wing opens by the scissor movement, see. above, there 3 and paragraphs [010], [032], [033] and [034] with respect to the local ones 6 and 6a with regard to the angular engagement part for coupling to the local driving pin Z.

The Improvement relates to a further training, wherein a further compact arrangement is to propose, a ease of installation should be given, the said additional locking either already may be provided, or easily as a supplemented component to a suitable Place to attach to both such scissor assemblies motor to be able to operate who do not own this additional lock, those too To be able to deliver scissors arrangements, which provide such additional locking in the sense described. In addition, the task is before, the coupling of the drive convert the traveling or spindle nut, as a synonym for a longitudinally displaced unit by a rotationally driven spindle, with the or the scissors and possibly provided additional locking reliable to reach. After all should favor the attachment of several scissors on the same housing and be facilitated from the mounting side ago.

Is solved This extensive task with claim 1, or one of there circumscribed alternative groups, and with claim 15, which specifically in feature (a) assumes that the engagement arrangement as an additional element via a push member can be attached to a mounting point, which with the traveling mother communicates.

With the solution according to the invention is in the case reduces the cross-section of the scissors arrangement, and (as a result) Installation space created inside, for receiving drive and his electrical control components.

rotational movements or rotational loads can be kept away from the traveling mother and there will be a possibility created to couple several scissors together over a single pole, which is simplified by the assembly effort and the handling. This is the coupling of the scissors to be issued from the traveling nut decoupled or spaced. The hiking mother is of potential incurred relieved small pivoting movements of the scissors. These will rather the linkage assigned as a substantially round thrust member below the scissors are arranged and guided inside the housing, around which at least one, preferably several scissors arrangements operate with the same push rod to can (Claim 1, feature c4).

Under an operation is here both in terms of scissor arrangements as well as in terms of these driving push rods meant a movement, the one Setting a grand piano (from Outside inside). Alternatively, an exhibition (from inside to outside) can take place. Also holding, so holding a wing in a predetermined Angular position belongs to the possibilities which one with one pressing can reach. After all is a peculiarity of keeping closing as such, which either within the scissors over suitably trained handlebars takes place, or over a Leerhub of the linkage, so that a closing lock possible is, also in the sense of a forceful hold of the Scissors in the closed state. These "operations" can be successively can occur, but can also occur alone or in any combination.

Become Several scissors arrangements provided, they can on the one push rod threaded and then on the case be determined. When fixing the scissors grab scissor arms at least in sections into the housing, with the push rod to be coupled, but are with their essential Ausstellteil outside of the housing arranged to a large travel for the to be operated wing available too put. The housing itself is elongated (claim 1, feature a) to at least one, prefers to pick up and hold several scissors at a distance. Inside the case is a motor drive (usually electric motor) provided, to drive a spindle rod coupling (claim 1, feature c5). It sets the rotational movement of the spindle rod in a longitudinal movement the hiking mother, which for the push rod described causes a longitudinal movement, for Actuate the on the housing arranged scissors arrangement.

A second actuation may be added to the first push member (claim 1, features c3, c5). The traveling nut then actuates two synchronous, elongate push members to both to cause the operation of the scissors, as well as to control the additional locking by a pushing movement. Both pushing movements run synchronously with the movement of the traveling nut in the longitudinal direction.

The Thrust links are opposite each other arranged, wherein above the drive, the thrust member for the scissor assembly and below the drive (in cross-section) the push member for the engagement assembly is provided as an additional lock. The engagement arrangement becomes doing one over elongated pusher operated, which is not inside the case is arranged, but outside of the housing near the bottom of the case guided is (claim 6). The push rod for the actuation of the at least one Scissor assembly is provided within the housing (claim 6). But both push members are guided within "longitudinal areas" of the housing, which implies that they may be located within or in the immediate vicinity (claim 1, feature c3).

The mentioned longitudinal areas determine two elongated spaces, which have a defined task. A lying between these spaces elongated interior is high enough, an electric drive record and take the bulk of the interior of the profiled housing. In addition is in the interior as an axial sequence of the drive, the spindle rod assembly provided with a spindle rod and traveling nut, which in turn in the upper longitudinal space for coupling with the push rod for the scissors engages, on the other hand a mounting option for the second push rod in the other, opposite longitudinal space to disposal represents where the thrust member for the engagement arrangement can be mounted for additional locking. None of the opening scissor members reaches into the interior, but stays in the area of the upper, elongated guide space above the drive space, roughly speaking the elongated one Push rod for the operation the shears define the lower end of the upper elongate guide space, possibly slightly located lower by threading eyelets of Scissor links, on the one hand only for leadership, on the other hand, by Fixing with mounting screws for the transmission of forces This thrust member can be arranged. After the second push member on the opposite longitudinal section is preferably configured flat (claim 8), the lower elongated guide space in its height Lower, than the upper, but both installation spaces are significantly lesser Height, as the interior for receiving the electric drive and the spindle rod with hiking mother.

This huge space is able to electrical units, switching units or other controls for to record the electric drive, as well as the spindle / nut arrangement. examples for electrical components are switching power supplies (primary voltage of the grid), transformers (Secondary 24V), Shutdown, lift control or overload circuit, sequential control or synchronous control (claim 12). They are not mechanical Connections between two scissor assemblies in the longitudinal direction are spaced apart, here projecting into this interior, but for the activity rod used for this scissor remains above this in the wes. cuboid elongated installation space.

Of the in the case lying installation space is not due to penetration of sections of the Scissor arrangement in its height impaired. He gives room for the drive and additional electrical units that can be inserted on circuit boards. Of the Space between motor and terminal extends (claim 13), preferably it starts at the, the spindle drive and the spindle opposite Front end of the elongated housing (claim 14). The power line can be introduced through the front become.

In the elongated housing is preferably only one drive provided, but preferably several Scherenanordnungen fixed (claim 1, feature a). The transfer the actuating movement on the scissor assembly via the one of the elongated Pushing members; the operation the engagement arrangement takes place on the opposite side by the other of the elongate push members (claim 1, feature b). The engagement arrangement triggers their engagement with a driving pin when issuing the scissor assembly, wherein the engagement assembly comprises a first portion outside the housing and has a second section. The first section extends essentially parallel to the plane of movement of the scissors (median plane of the housing), the operating level of the Scissors is composed of several links.

The Engagement arrangement engages laterally in the area of the drive (Claim 1, feature c1), wherein the push member itself already outside of the housing guided is (claim 1, feature c2). The picking happens with one to the movement level de r. Scissors extending substantially vertically Section of the engagement arrangement, which preferably a substantially angular Design of the entire Eingreifanordnung results, in turn is arranged on the elongated thrust member, that of the traveling mother longitudinal actuated is (claim 7).

The protruding of the engagement arrangement in Area of the drive shows that the longitudinal region for guiding the Eingreifanordnung and the associated push member requires only a small height. They do not reach so far into the interior of the housing that the drive would not be attachable where the pusher member is able to move with its longitudinal movement between its end positions back and forth. The coupling to the motor drive via a penetration through the bottom of the housing and the sliding guide of the elongate thrust member as a flat rail is made by angular webs in the bottom region of the housing (claim 1, feature c2).

The outer education of the housing has two front sides and two free sides. On one of the End faces, the at least one scissor assembly is attached. The two free sides are approaching each other, which results in that the opposite end faces not the same width (in the direction perpendicular to the longitudinal extent of the scissors arrangement) can be configured (Claim 1, feature c6).

Advantageous is the arrangement of the drive below the longitudinal extent of a pair of scissors, preferably one of the several scissors (claim 1, feature c7). The Attachment of the engine is here immovable during operation. It can the entire motor drive below the scissor assembly be placed, but also only an essential section of this Motors is suitable for placement below the scissors, preferably more than 50% of the longitudinal extent of the electromotive drive. From the area of the longitudinal extent the scissors, however, the spindle rod extends out, which the hiking mother leads. In this way, the predominantly arranged below the scissors assembly Motor an actuating movement outside of longitudinal area cause the scissor assembly, which on the at least one, preferably two retransmitting synchronously elongated thrust members on the one hand, the scissor assembly above the electric motor and on the other hand, the engagement arrangement below the electromotive Drive.

Of the compact space below the scissors thus carries the engine, both actuators (Push and pull) and projecting from one of the actuators Eingreifanordnung for controlling the additional locking.

On Claim 2 is emphasized, the at least two of the above Combined C features, but preferably addresses several of these features, which can also be present in combination and not only as an alternative. The same applies to Claim 15 with respect to the local C-characteristics, which feature with (a) this claim can be combined.

there the Eingreifanordnung has no compelling need, but can be provided so that it is mountable on the spindle nut and the scissor assembly is formed overall, for this Application modular to be able to be. But also a scissors arrangement completely without mounting option for the Eingreifanordnung or the associated elongated pusher member is covered by claim 15. Hereby finds one of the combinations of the C features with the feature (a) instead, which corresponds to the feature (a) of claim 1. Regarding the explanation of the C features is based on the previously explained features c4, c6 and c7.

The Eingreifanordnung, provided provided, protrudes beyond the housing dimension, is "arranged abragend", even if they from guides in a longitudinal area guided will, according to the description already outside the actual interior of the housing is located. The querying speaks from leaving the cross-section transverse to the longitudinal extent in a sectional view and should explain that with this protrude a Intervention in the rebate of the actuated linkage is possible, However, even if the scissors outside of this rebate on the flat side of the frame is attached.

The Clutch of the traveling mother with the one pushing element, which in turn firmly and / or slidably coupled with scissor arms of the scissor assembly is done over such a bearing, which limits rotational movements, but axially directed longitudinal movements not or hardly (claim 9). For this purpose, the push rod can be plugged in a forked Recording after the scissors arrangements on you threaded were. Nevertheless, a low mobility remains in more extensive Direction at the depository exist, which the compensatory movements for the inclination represents the plane of movement of the scissors. The push rod is as Intermediate rod between the hiking mother and the at least one, preferably two or more scissor assemblies provided and thereby designed in the sense described as round bar preferred what the threading the scissor links facilitated (claim 10). In contrast to this is the second push member for the drive of the engagement arrangement preferably formed flat to so little height as possible to take (claim 8).

After threading the scissor assembly and placing the scissors in their positions on the housing or slightly engaging in the housing to the first push rod fixing the push rod can be done at the bearing point to the traveling nut (claim 3). The hiking mother is doing this via an upwardly projecting arm this Bearing so guided in a slot an intermediate wall of the housing that they hardly or only little rotational movement experiences, but the rotational movements of the scissors are already compensated by the bearing described and no longer transferred to the traveling nut. A comparable slot guide may be provided opposite to the bottom of the elongate housing in a limited longitudinal extent to couple the preferably flat designed second push member with the traveling nut. The push member does not have to be decoupled here from the traveling nut with regard to rotational or pivotal movements, but this decoupling can be taken over by the longitudinal guide on the ground, which is preferably made of two webs, which are each formed angularly in cross section (claim 11), but at least one side preferably opposite to each other on both sides of the bottom edge-side openings, for the passage of the Eingreifanordnung and to project for engagement in the rebate when assembled scissor assembly on the frame.

The lateral opening or opening of the guides, in particular angular Footbridges, done on one length, which at least the travel of the elongated thrust member in lower longitudinal area of the housing but is preferably larger to mount this To allow pushing member with an engagement arrangement arranged thereon. For this purpose, the elongated, preferably flat lower thrust member first inserted into the one side of the edge guide until the End of the tour moved forward, then aligned flat and parallel to the ground, with the projecting engagement arrangement in the lateral recess of a the bridges fall, subsequently one piece moved back, around the other long side lateral guidance provided guides to intervene and then finds a fixation the second, flat push member instead of at a mounting location, wherein a mounting pin passes through a slot and with the traveling nut longitudinal is immovably connected.

The Engaging arrangement (with the associated thrust member) becomes so over the inside of the housing Placed assembly site, previously threaded and simultaneously prepared for leadership, to their axial adjusting movements in longitudinally displaceable direction to be able to record.

The Coupling arrangement near the one end of the preferably flat trained Thrust member (claim 8) corresponds in terms of location of the mounting point on the Traveling mother, with the traveling mother in her utmost (farthest from the drive) Adjustment is moved, for attaching the additional lock in extent described, Procedure and scope.

embodiments explain and complete the invention.

1 . 2 and 3 illustrate in an overview two side views and a sectional view. The cut is through the middle of the 2 placed and defined along a median plane E, which also serves as a recess plane or plane of movement of the scissor assembly 7 can be seen, which is displayed in the middle with her several illustrated scissor arms in this level. In a deployment movement and a wing, which holds arranged at the front end of the scissor assembly via a wing pedestal, the scissors tilts slightly downward relative to the scissor plane E to compensate for the lowering of the upper spar of the wing. This pivotal movement is in the attachment of the scissor assembly 7 in the illustrated housing 1 allowed, so that the scissors assembly is not only in the axial longitudinal direction is movable, but a tilting movement about the illustrated push rod 80 (for push and pull) can perform. On this push rod 80 which inside the housing 1 is guided, several scissor links are threaded with sleeves, with two hinge points 31 . 32 are provided to swing around the scissor members, with an additional large main scissor arm, which swings controlled by the auxiliary arms.

A power transmission via an intermediate member 82 , which by means of grub screw 81 at the push member 80 is arranged and at a left movement of the push rod 80 which is preferably round, but at least substantially configured, is moved to the left. In this case, an idle stroke lead to an unlocking of a locked in the closed position scissor assembly, with a subsequent swiveling and a slight downward tilt, as described above, in an attached state on the frame.

The pivot points 31 and 32 as bearing points are symbolically explained in the cited script, only there are the scissor arms and their movement executed differently. From the function of the two pivot points 31 . 32 But is quite comparable, so that for further explanation of the scissor arms and the raising movement of the scissors on the font described above EP 1 223 287 A2 can be referenced.

It was explained that the lower side (bottom side 1d ) of the housing 1 is to be arranged on the spar of the frame. This is in 1 shown below, opposite of the scissor assembly 7 , The housing 1 is elongated, but narrow and has two free sides 1a . 1b which approach each other slightly arcuate upward to reach a narrower web, which forms the top on which the scissor assembly is mounted. The lower end area is particularly in 6 as a broader, which forms the mounting surface for attachment to the frame. The scissors are in all representations of the 1 . 2 . 3 such as 6 , as well as the perspective representations of 4 . 5 shown in closed condition.

The 6 illustrates a compact construction in the closed state of the scissor assembly 7 ,

The overall device itself is also referred to as a scissor assembly, although it is a scissor assembly 7 , or even several independent scissors arrangements 7a . 7 to 9 can have. The local version contains a longer housing 1* , in a practically same cross-sectional structure, as out 6 it can be seen only in the longitudinal direction a plurality of scissors are arranged on the housing so that they can perform the slight tilting movement and with the push rod 80 are coupled by threading with respect to their individual scissor members, for transmitting forces from the push rod 80 out.

The Actuate will be referred to as either issue, set or position be understood. Alternatively, a lock in the closed position can take place. These possibilities are not cumulative, but alternative and each independently possible, too in certain sequences of a work cycle.

The elongated housing after 1 with a first longitudinal extent is longer than the second longitudinal extent of a motor drive 2 , which is much shorter than the length of the scissors and also much shorter than the length of the housing in the longitudinal direction. The motor is substantially completely below the scissor assembly 7 in the interior of the housing 1 arranged. He controls a spindle rod via a gearbox 3 , on which in turn a traveling mother 4 is performed as a translator threaded between rotational and pushing movement. It moves longitudinally in the space between the right end 1c of the housing 1 and the right end of the drive 2 , The drive is preferably an electric motor drive with a control circuit and a limit stop (or a load shutdown) at a start against a stop.

Below the engine are lateral guides 71 . 72 arranged as cross-sectionally angular webs which are interrupted approximately centrally. It who free the lateral openings through which an engaging arrangement, to be described later, can protrude to temporarily contact with a locking linkage of the wing and upon opening of the wing via the issuing of the scissors arrangement 7 to break away from this driver pin as a temporary contact. This is described in detail in the introductory part.

It is preferably no further motor drive provided, but only the one who in 1 under the first scissors arrangement 7 and in 9 under one of the two scissors arrangements 7 . 7a is arranged. This engine is capable of over the spindle rod 3 , the hiking mother 4 as a converter and a vertical coupling 4a (as a sliding bearing) the push rod 80 to operate, in the longitudinal direction to the left and right according to 1 , This opens and closes a scissors arrangement 7 or both scissors arrangements 7 . 7a to 9 with a mechanical coupling via a single, continuous rod 80 for push and pull ("push rod").

There are three spaces formed by the described construction. These rooms are each elongated. There is an upper elongated longitudinal area as the upper space, which is the push rod 80 receives. There is a much higher interior space, in which on a relatively short section of the motor drive 2 is placed axially immovable, to a torque on the spindle rod 3 to apply and the scissor assembly on the spindle rod coupling 3 . 4 to press. Below the drive 2 provided with a very low height another longitudinal area is provided which receives a further elongated actuator in the sense of a flat push member. This is in 7 explained in more detail and in the previously described 1 to 6 and 8th omitted for clarity.

The lower sections of the respective scissors arrangements 7 . 7a only engage in the upper elongated longitudinal area as a second space. The inner space as the first, largest dugout room 20 takes the electric motor drive 2 on, possibly additional components and control groups, which are supplied via a power cable, the front side of a terminal 21 or such a terminal block through a cable gland 22 is supplied. This terminal block 21 is accessible through a cap for a power cable, which is in 1 with the grommet in section and in 6 by supervision of this cable gland 22 is easily apparent. After the third, lower elongated space is very narrow in height, remains the larger height and thus the largest installation space 20 inside for the electromotive drive. He controls the spindle rod coupling, which is also placed in this space. There then remains a very large space for other components that can be inserted between the end of the motor and the front end at the terminal or inserted in web guides on boards. This large space extends far below the scissors arrangement.

Are several scissors after 9 provided, the space may be 20a also extend entirely below a pair of scissors, if only one drive is arranged under one of the several scissors. Here is the terminal block 21 placed for the power cable beyond the far end of the scissors on the front side of the elongated housing and the free space runs under at least two of the housing arranged on the scissor assemblies.

The flat push member 70 is threaded so that this flat shear member as a flat rail edge of the webs 71 . 72 on the ground - near the ground - and in sync with the push rod 80 can perform a pushing movement in the longitudinal direction in one and the other direction. It is about one to the ground 1c of the housing facing mounting point 73 at the hiking mother 4 coupled with this in an axially immovable manner. This coupling is detachable or constructed so that it does not exist before inserting this flat push member, and is made later after insertion. Likewise, the coupling is over the camp 4a (the towering coupling) on the opposite side between the push rod 80 and the spindle nut not yet provided before the scissors assembly (s) not on the push rod 80 are then threaded to be fixed relative to the housing, with a subsequent positional fixation of the push rod 80 in the warehouse 4a which in the 8th is explained in more detail.

This camp 4a allows a transmission of axial forces, without significant play, preferably without any long play, but allows a limited rotational movement of the push rod 80 to the described tilting movement of the at least one scissor assembly 7 . 7a be able to catch and compensate. Because of this clearance in the direction of the movement of the scissor assembly does not transfer to the traveling mother 4 but will be in stock before 4a with the two upstanding finger-shaped, spaced webs 4a ' . 4a '' intercepted.

The insertion in the web arrangement 4a ' . 4a '' is done by a flattening of the push rod on both sides 8th so this is a gutter 80a with a substantially cuboid design and two end faces lying on both sides 80b ' . 80b '' receives, which from the outside on the fingers 4a ' . 4a '' nudge, when axial forces are to be transmitted. The hiking mother 4 is in 8th shown only schematically, but the towering bearing arm 4a it can be seen which in 1 through a slot 4b protruding is shown. The slot is in an intermediate wall 1d provided which wall below the top wall 1e and located within the housing. Along this slot becomes the arm 4a moved, in particular guided, to be able to give an additional circumferential support and to avoid that extensive forces on the traveling nut 4 Influence.

The slot 4b in 1 is formed at least as long as the longitudinal stroke of the push rod 80 is desired and the longitudinal stroke of the spindle nut 4 over the spindle rod 3 is to be caused, ie between the final stroke near the motor drive 2 , which indicates the extended position of the scissor arms 7 symbolizes, and the right stop stroke at the end 1c the interior in front of the cap of the housing, which the closed state, possibly also the locked in the closed position state of the scissor assembly 7 symbolizes.

The interruption of the marginal webs 71 . 72 is in 3 as well as in 1 and also especially in 5 , Here is the second push member 70 inserted as a rail and it takes an angular engagement arrangement out of the edge opening out. The push member is at its one end to the mounting point 73 set, with a notched pin to be used for example by a longitudinal slot 74 engages the ground and this longitudinal slot has a length which is at least as large that the axial stroke movement of the first control rod 80 can be met and no blocking takes place on the bottom side.

The same application can be found in the 10 and 11 Again, the perspective views of the scissors after sectional view of the 9 are. Again, a bottom side inserted flat rail is used by an end provided opening attachment to the mounting location 73 to get which of the spindle nut 4 assigned. She also grabs the slot 74 ,

Compared to the 1 to 3 are the 9 to 11 directly comparable, only with a longer housing 1* provided, a approximately centrally disposed between the scissors arrangements Aussparbereich with the length a, which corresponds to that area which in 1 below the drive for protruding the Eingreifanordnung 40 , arranged on the flat rail 70 serves. Comparable to 1 is in 9 to 11 the motor drive 2 arranged below one of the scissor assemblies, with directly comparable attachment of the spindle rod coupling 3 . 4 ,

The mounting point 73 and the slot 74 must not be provided if the scissors only for issuing with the at least one scissor assembly 7 is used. However, it is advantageous to prepare these scissors already functionally that an additional synchronous with the push rod 80 running rail can be inserted, which after fixing at the mounting location 73 is able to make an additional lock on a wing. Whether this additional locking is then regularly distributed together with the scissor assembly is another question. There is only the possibility, not the compelling necessity. It is advantageous to provide this option and to complete one or the other variant when delivered, without having to store additional components.

With reference to the 7 the engagement arrangement will be explained in more detail as an angularly projecting coupling member. For its function and the coordination with the movement (the issuing or setting) of the scissor arms or is made to the above-mentioned document and the statement there. If the scissors arm approaches the wing, a driver pin located in the closing blade fold space and projecting on a locking linkage engages in the recess of the engagement arrangement, hence the name of this angle-shaped driver device made of flat steel. If an intervention has taken place, a longitudinal movement can take along the driving pin on the wing and actuate the locking linkage so that locking pins provided elsewhere are moved behind corresponding locking pockets, which is synchronously coordinated with the scissor-closing operation or the already practically attached wing on the frame happens.

At the Issuing happens this locking the tie bar vice versa. The driving pin is moved to release the locking linkage, the Scissors will start afterwards exhibit and solve it the engagement arrangement more and more out of the wing the folding space moved out driving pin. The procedure dissolves when Issuing the scissor assembly.

The coupling in the sense of a coordinated sequence control for the exhibition of the scissors arrangement and the movement of the locking pin is done with the common traveling mother 4 which longitudinally moves two synchronously running, elongate push members to move the scissor assembly and the engagement assembly equally during operation. The at least one scissor Order is operated via the (round trained) rod, which is carried out starting from the spindle rod coupling of the motor drive. If two or more scissor assemblies are arranged on the housing, they are displayed synchronously, operated with the same, continuous push rod.

The engagement arrangement as an angular driver member is over an elongated rail as. Actuator with the traveling nut 4 coupled. This rail has no thread and is not designed for rotational movement, but it is very flat to be able to be guided in the low height of the lower longitudinal region, outside the interior of the housing and guided on an edge side of the bottom of the housing, preferably of angular Bars, which have an undercut due to their shape.

The operation of the round bar 80 takes place within the housing in an elongated guide space (longitudinal area) which is designed to be higher in the center-plane direction E, as the just described lower longitudinal region at the bottom of the housing for receiving and guiding the flat push member. This is preferably outside of the housing, whereby the projection of the angular Eingreifanordnung facilitates and without actual housing breakthrough is made possible. Only the guide is interrupted, with continuously closed housing on the floor, with the exception of the slot provided, for coupling the flat push rod to the traveling nut.

The insertion of the flat push rod in the ground level guides happens after the 7 , First is in 7.1 when using only one Ausstellanordnung 7 on a housing 1 a first length of a flat push member 70 provided on the side riveted an angular flat piece is provided, which forms the engagement arrangement for the driving pin (not shown). The angle has two sections 40b . 40a , The perpendicular to the plate extension 70 extending angle section 40a protrudes in a plane parallel to the median plane corresponding to section AA of 2 from the case. The vertical section 40b engages laterally through the recess of the longitudinal guides 71 . 72 , The extension of the section 40a runs at a distance to the median plane, which is greater than half the width of the housing 1 ,

The flat rail 70 gets into her guided position as well as 7.1 initially shows. The left end there with a receiving opening 75 gets into the left groove guide 71 . 72 inserted and enters a stop position, such as 7.2 shows. Here, the outer end is at the stop 1c reached, which forms the front end of the floor (the cap). The recess between the two guides 71 . 72 is dimensioned in the longitudinal direction with the dimension "a" so that the other free end of the flat rail is not on the guides 71 . 72 rests, but can be inserted flat and after a small return stroke .DELTA.a is also performed on both sides, like the 7.3 illustrated. Here also the position is reached, in which a fastening device, such as a grooved pin, through the opening 75 near the end of the plate 70 is inserted and the axially and radially immovable coupling with the invisible wall nut 4 reached.

The operational situation is reached and with an additional mechanical affirmation (fig 7.4 illustrated), can ensure the assembly in the area 73 . 74 . 70 be achieved. Subsequent movements of the traveling mother 4 then go synchronously and simultaneously on the two parallel thrust members 80 . 70 over who perform different tasks as described above.

7.5 illustrates a small feed movement with a fixed notched end, but still largely in the closed position of the scissors and thus in the end position near, but spaced therefrom longitudinal position of the engagement arrangement with arranged thereon flat thrust member 70 ,

For the application of the same push element 70 with engagement arrangement 40 with a longer housing shape 7.7 , will be an extension 70a from a same flat training with end-side mounting hole 75a used. It is connected via a plug connection, which allows axially immovable coupling at the other end, with the thrust member described above 70 and its coupling opening 75 connected. The edge groove guide 71 . 72 leaves so much play that two layers of flat metal can be longitudinally guided without blocking. The assembly then takes place as previously based on the 7.1 to 7.4 explained, only with reference to 7.7 which already shows the state which is in 7.5 was reached after fixing the grooved pin.

The placement of the essentially round push rod 80 within the housing should again with 8th be clarified. There is the top 1e of the housing 1 plotted, which is the upper end of the slight rotational movements of the rod 80 permitting bearings 4a . 4a ' . 4a '' covered, with a bearing arm 4a from the hiking mother 4 to the fork for holding the rod 80 leads. This intermediate arm 4a is through a groove 4b led, which in an intermediate wall 1d inside the case and below the scissors, but above the electric drive 2 is arranged. It serves as a guide for either the push rod 80 or auffä delte thrust members, as shown in the sectional view of 1 is apparent.

After threading the scissors arrangements 7 . 7a becomes the molded sheet 80a in the fork 4a ' . 4a '' inserted (from above) to remain limited rotationally movable but in the axial direction exactly with the longitudinal movement of the traveling nut 4 to be coupled.

To the dimensioning of the interruption on the length a of the marginal guide 71 . 72 It should be noted that it will be large enough to follow the recording procedure described 7 to enable. At the same time, however, it must not be too large to permanently have one on both long sides and both on this side and also beyond the engagement arrangement 40 to provide secure guidance in four places in all operational positions. Therefore, the recess is not longer than the intended maximum travel of the threadless thrust member as a flat rail 70 and at least smaller than its total extension. The far end of the break (from the mounting point 73 seen from) is not closer to the inner end 1c the bottom guide (near the cap) as the push member is long, but slightly further away to the insertion after 7.2 to enable. Slightly rounded edges of the push member 70 facilitate this loading procedure.
