Detailed description of the figures

In the following, various aspects of the invention will be explained with reference to the figures.

Fig. 1 shows a perspective schematic overall view of the reclining device 10 according to the invention with sprouts 140 (see Fig. 6 ) of the ergonomic couch, where the outside 60 (see Fig. 5 ) and inner 80 (see Fig. 5 ) Side parts are shown transparent. Not shown are the reinforcements (wooden strips) 160 (see Fig. 7 ), after the introduction of the sprouts 140 (see Fig. 6 ) into the notches 98 (see Fig. 6 ) of the side parts 90/130 (see Fig. 5 ) (Detail 150, see Fig. 6 ) are glued on this (see Fig. 7 ) in order to guarantee the strength (prevention of bending stress due to excessive load) of the backrests.

Fig. 2 shows in perspective the already fully assembled lying surfaces (backrest 23, seat 24 and foot 25) in different positions (but here without the interaction between external 60 (see Fig. 5 ) and inner 80 (see Fig. 5 ) Side parts and slide 70 (see Fig. 5 ). The sitting position 20 is shown with erected back part 23, lowered seat surface 24 and angled foot part 25. The half-lying position 21 is shown with angled backrest 23, half raised seat surface 24 and half raised footboard 25. The lying position 22 is with horizontal backrest 23, horizontal seat 24 and horizontal footboard 25 shown. Any arbitrary position is adjustable between these extremes and is held there by means of the self-inhibition function described below. Only by the interaction of the lying surfaces with the guides in the inner side parts 80 (see Fig. 5 ) of the couch and the simultaneous inhibition of movement by means of the bearing stock 102 (see Fig. 5 ) in the long hole 71 (see Fig. 5 ) of the slider 70 (see Fig. 5 ) and its simultaneous jamming in his leadership (cutout 61 (see Fig. 5 ) in the outer side part 60 (see Fig. 5 ) and cutout 81 (see Fig. 5 ) in the inner side part 80 (see Fig. 5 ) this functionality is achievable. In this case, the axis of rotation is in the storage stock 101 (see Fig. 5 ) of the backrest 23. When the backrest 23 is loaded in the upper region by the person leaning against the backrest 23 and at the same time relieving the seat surface 24 - person stretches, the resulting torque on the stockstock 101 (see FIG Fig. 5 ) by means of lever law, via the joint connection between the backrest 23 and seat 24 (storage stock 102 (see Fig. 5 )) exerted a push on the seat surface 24. This is in turn by the hinge connection between the seat 24 and foot 25 (stock stock 103 (see Fig. 5 ) is forwarded to the foot part 25 and ensures that the foot part 25 at the open end with the storage stock 104 (see Fig. 5 ) (by the skew 84 in the inner side part 80 (see Fig. 5 ). This is only possible with simultaneous operation of the slide 70 (see Fig. 5 ) through the side knob 50/51 (see Fig. 9a ) to cancel the self-inhibition.

The self-inhibition arises from the interaction of the following components storage stock 102 (see Fig. 5 ), an arcuate or ¼-circular cutout 82 (see Fig. 5 ), Slide 70 with associated long hole 71 (see Fig. 5 ) and the hand knob 50/51 (see Fig. 5 ), as well as the milled guides 61 in the outer side part 60 and the milled guide 81 in the inner side part 80 (see FIG Fig. 5 ).

Self-inhibition is based on the friction principle. That is, the slider 70 with its obliquely milled long hole 71 (see Fig. 5 ) is detected by the stock stock 102 (see Fig. 5 ) pressed either up or down, depending on loading or unloading the seat. When loading the seat down, with relief of the seat to the top. This is about the positive connection of the slider 70 (see Fig. 5 ), with the upper or lower edge of the cutout 61 in the side part 60 (see Fig. 5 ) creates a friction between these surfaces. Thus, the slider 70 (see Fig. 5 ) as two oppositely directed but interconnected wedges extending between the stockstock 102 (see Fig. 5 ) and the respective upper or lower edge of the cutout 61 in the side part 60 (see Fig. 5 ) jam. Thus, neither a forward or backward movement after Frictional connection of these components possible. Only when relieving the storage stock 102 (see Fig. 5 ) is the slider 70 (see Fig. 5 ) again by means of the side knob 50/51 (see Fig. 5 ) or the armrest 180 (see Fig. 4 ) and the self-locking can be solved.

The self-locking is also functional, if one reverses the principle 180 ° and reverses the roles (active and passive) of the components. That is, not the stock stock 103 (active) applies to the slider 344 (passive), or as in FIG. 16c and 16d on the slide 513 (passive) or slide 518 (passive) from a push / push movement, but vice versa - the slide 344 (active), or as in FIG. 16c and 16d the slider 513 (active) and slider 518 (active) exert a push / push movement on the storage stock 103 (passive). In general, only the role (active and passive) of the components changes, but the basic principle is retained. It is only important that for the respective reacting component (passive) (either slide or stock) a small "game" is constructively provided to allow the jamming.

This functionality lifts the present lounger from many mechanical loungers available on the market since it does not require any action on the part of the user to maintain the position taken. In order to prevent the self-adjustment of the assumed position, the movement of the bearing block 102 in the ¼-circular cutout 82 (see Fig. 5 ) of the inner side part 80 (see Fig. 5 ) in his up and down movement. This inhibition is achieved by the storage stock 102 through the ¼-circular cutout 82 (see Fig. 5 ) into the long hole 71 (see Fig. 5 ) or 261 (see Fig. 4 ) of the slider 70 (see Fig. 5 ) or 260 (see Fig. 4 ) enough. This long hole 71 (see Fig. 5 ) or 261 (see Fig. 4 ), which the slider 70 (see Fig. 5 ) or 260 (see Fig. 4 ) virtually divides into two opposing wedges, blocks the free movement of the storage stock 102 (see Fig. 5 ) in the ¼-circular cutout 82 (see Fig. 5 ) by the fact that the long hole 71 (see Fig. 5 ) or 261 (see Fig. 4 ) in its orientation almost always transverse to the ¼-circle movement direction (up and down) of the bearing stock 102 (see Fig. 5 ) stands. The through the storage stock 102 (see Fig. 4 ) over the long hole 71 (see Fig. 5 ) or 261 (see Fig. 4 ) on the slider 70 (see Fig. 5 ) or slider 260 (see Fig. 4 ) exerted pressure (up or down) causes this in each case with the top (during upward movement) and lower edge (during downward movement) in the milled guide 61 (see Figure 4 ) and 81 (see Fig. 5 ) wedged. The components are deliberately installed with a little "play" to allow this jamming at all. The main part of the friction arises between the milled guides 61 and 81 (see Fig. 5 ) and the respective ends of the upper and lower edges of the slider 70 (see Fig. 5 ) or 260 (see Fig. 4 ).

As long as through the storage stock 102 (see Fig. 4 ) Pressure on the slide 70 (see Fig. 5 ) or 260 (see Fig. 4 ) by means of the long hole 71 (see Fig. 5 ) or 261 (see Fig. 4 ) (eg by leaning against the backrest 23 (see Fig. 2 ) or relief this and load the seat 24 (see Fig. 2 ) is exercised, thereby the respective direction of movement is blocked. When changing the direction of movement of the bearing stock 102 (see Fig. 4 ) and the inevitable relief of the long hole 71 (see Fig. 5 ) can be the slider 70 (see Fig. 5 ) or 260 (see Fig. 4 ) move freely until the storage stock 102 (see Fig. 5 ) again on the opposite side of the long hole 71 (see Fig. 5 ) or 261 (see Fig. 4 ) meets. Then this direction of movement after a short jerking (triggered by load change and re-jamming of the slide) is blocked again. Only with relief of the stock stock 102 (see Fig. 5 ) and simultaneous operation of the slider 70 (see Fig. 5 ) or 260 (see Fig. 4 ) by means of the side knob 50/51 (see Fig. 5 ) or the armrest 180 (see Fig. 4 ) the self-inhibition can be canceled. Since both slides 70 (see Fig. 5 ) or 260 (see Fig. 4 ) are moved simultaneously and both hands are needed, is also the already low risk of injury by possibly pinching a finger in one of the guide cutouts 62, 82, 83, 84 (see Fig. 5 ) when adjusting the position, practically impossible. These properties make the use of this lounger particularly attractive in the medical and therapeutic fields. In the FIG. 16a and 16b shown self-escapement differs only in that the direction of movement of the storage stock 103 (see Fig. 5 ) not transverse to the respective long hole in the slide 344 (see Fig. 16a ) and 345 (see Fig. 16b ) runs, but obliquely. By shifting the self-escapement from the range of rotation of the bearing stock 102 to the storage stock 103, the arcuate cut-out 82 of the inner side part 80 (see Fig. 5 ) accounted for. The self-locking is in this case not generated by a ¼-circular movement, but by a push / push movement of the storage stock 103 on the slider 344, or as in FIG. 16c and 16d on the slide 513 or slide 518. This principle is also applied to the seat length adjustment (see Fig. 19 ), with slide 535 (see Fig. 18b and Fig. 18c and Fig. 19 ), the guide stick 532 (see Fig. 18a, Fig. 18c and Figure 19 ) and the seat portion 530 (see Fig. 17a . Fig. 18a . Fig. 18c and Fig. 19 ) and the armrest locking slide 601 (see Fig. 21a . Fig. 21b and Fig. 22d ) in conjunction with the Arretierungsstange 603 (see Fig. 21a . Fig. 21b and Fig. 22d ) for the rocking chair variant.

There is generally the possibility of symmetrical self-locking with blocking in both directions of movement (with parallel flanks of the oblique slot (71, 261, FIG. 271, 281, 291, 301) in the slider (70, 260, 262, 270, 280, 290, 300, 321, 331, 344, 513, 518)) or asymmetric self-locking with blocking in only one direction of movement with the preferred lock - / sliding direction, which is characterized by different angles of the slot (71, 261, 271, 281, 291, 301) in the slide (70, 260, 262, 270, 280, 290, 300, 321, 331, 344, 513, 518 ) for push / push direction. That is, the two edges of the slot are not parallel, but have different pitch. In blocker direction (leaning against the backrest), a shallow angle is used to set the maximum friction or as required by the application. In the opposite sliding direction (raising from the sitting position), a steep angle is used to set the friction minimally or depending on the application required. This results in an asymmetrical sequence of movements, which allows full braking action (self-locking) in one direction, and maximum sliding in the opposite direction (very little or no self-locking). Fig. 3 shows with transparent components shown a lateral section through the couch to schematically represent this interaction of the aforementioned components in the three different positions (but here without the interaction with the slider 70 (see Fig. 5 ). The seating position 30, the half-lying position 31 and the horizontal reclining position 32. Very nicely recognizable in Fig. 3 how the lever position of the backrest changing over the three positions (here by way of example side part backrest 90 (see FIG Fig. 5 ), which extend over the axis of rotation in the hole 88 (see Fig. 5 ) in the inner side part 80 (see Fig. 5 ) or the storage stock 101 ( Fig. 5 ), the articulation between the backrest 23 (see Fig. 2 ) and seat 24 (see Fig. 2 ) changes. This is made possible by the ¼-circular cutout 82 (see Fig. 5 ) in the inner side part 80 (see Fig. 5 ) which the freewheel of the bearing stock 102 (see Fig. 5 ) only possible in it. The long hole 83 in the inner side part 80 (see Fig. 5 ) serves here on the one hand as a bearing for the joint connection (Lagerstocks 104 (see Fig. 5 )) between seat 24 (see Fig. 2 ) and foot part 25 (see Fig. 2 ) and on the other hand as a guide for this. The same applies to the oblique long hole 84 (see Fig. 5 ) in the inner side part 80 (see Fig. 5 ) and the storage stock 104 (see Fig. 5 ) of the foot part 25 (see Fig. 2 ). The movement of the lying surfaces in the opposite direction is by relieving the backrest 23 (see Fig. 2 ) reaches, in which the person straightens up by tensing the abdominal muscles in the couch while doing a pressure on the seat surface 24 (see Fig. 2 ) or the lower part of the backrest 23 (see Fig. 2 ) (below the pivot point 88/101 (see Fig. 5 )) and the backrest 23 (see Fig. 2 ) in the upper part (above the pivot point 88/101 (see Fig. 5 )). Again, this is only with simultaneous operation of the knob 50/51 (see Fig. 5 ) is possible to overcome the self-inhibition. This applies to the symmetrical Self-locking. In asymmetric self-locking movement is only blocked when leaning and not when erecting.

Fig. 4 shows with transparent components also shown a lateral section through the couch to schematically represent the interaction of the aforementioned components in the three different positions, but limited to the representation of the variant of the slider 260 (see Fig. 11b ), a section of the alternative outer side part 210 (see 10B ) with the cutout 211 (see Fig. 10b ), the side view of the bed frame and the section through the armrest 180 (see Fig. 9b ). Again, the three main positions seats 40, half-lying 41 and 42 lying are shown. It is very nice to see how the slider 260 (see Fig. 11b ) moves from right to left, if one moves from the sitting position 40 in the semi-recumbent position 41 and finally in the horizontal reclining position 42. You can also see how the storage stock 102 (see Fig. 5 ) in the inclined hole 261 (see Fig. 11b ) from below (sitting position 40), via the half-recumbent position 41 (centrally) moves up into the lying position 42, and thus the seat surface 24 (see Fig. 2 ) moved from the inclined position to the horizontal. Of course, the pivot bearing remains 88/102 (see Fig. 5 ) unchanged, but moves the hinge connection between seat 24 (see Fig. 2 ) and foot part 25 (see Fig. 2 ) horizontally in its guide-long-hole 83 (see Fig. 5 ). The armrest 180 (see Fig. 9b ) is thereby always pushed away from itself by the user of the couch, when this stretches, if this by relieving the seat surface 24 (see Fig. 2 ) and simultaneous loading of the backrest 23 (see Fig. 2 ) above the fulcrum 88 (see Fig. 5 ) the slider 260 (see Fig. 11b ) via the joint connection (storage stock 102 (see Fig. 5 )) and thus relieves the self-inhibition. After reaching the new desired position, the user relaxes and leaves the armrest 180 (see Fig. 9b ) and the slider 260 (see Fig. 11b ) wedged by the pressure of the bearing stock 102 (see Fig. 5 ) in the long hole 261 (see Fig. 11b ) in the new position in his leadership 211 (see Fig. 10b ). In the opposite direction, the user of the lounger simply tightens the abdominal muscles and simultaneously pulls on the armrests 180 (see Fig. 9b ). In this case, the mechanism is moved in the same manner as before, but in the opposite direction and one passes from the lying position 42 on the half-seat position 41 back into the sitting position 40. This is true in the symmetrical self-locking. In asymmetric self-locking movement is only blocked when leaning and not when erecting.

Fig. 13c shows an inner side portion 320 with all holes 85, 86, 87, 88, the long holes 83, 84, the Bogen-cut-out 82 (for the freewheel of the bearing block 102 (see Fig. 5 )) and the surface cutout 321 for receiving the slider 270 (see Fig. 11c ) as a guide, and the cutout 322 for the freewheel of the gear 194 (see Fig. 9c ) and the pinion 202 (see Fig. 9d ) and the bearing hole 323 for receiving the crankshaft 193 (see Fig. 9c ) or motor shaft 201 (see Fig. 9d ) in the side and top views as well as the cuts E / F and E '/ F' (for operation by the crank 190 (see FIG Fig. 9c ) and E '/ F' by the motor 200 (see Fig. 9d ).

Fig. 13d shows an inner side part 510 with all holes 85, 86, 87, 88, the slots 83, 84, the arc milling 82 (for the freewheel of the bearing block 102 (see Fig. 5 )) and the surface milling 501 for receiving the slider 270 (see Fig. 11c ) as a guide, and the cutout 484 for the upper bushing and the cutout 485 for the lower bushing (see Fig. 9e ) or the cutout 502 for the freewheel of the hub 481 (see Fig. 9e ) in the side and top view and the section E "/ F (see Fig. 9e ).

Fig. 14a shows the inner side part 80 with inserted slider 70 (see Fig. 5 ) and operating knob 50/51 (see Fig. 9a ) and the storage stock 102 (see Fig. 5 ). The section A / B shows the lateral actuation by knob 50/51 (see Fig. 9a ) with inner and outer side part 80 (see Fig. 5 ) and 60 (see Fig. 5 ), Slide 70 (see Fig. 5 ) and the storage stock 102 (see Fig. 5 )). The section A '/ B' shows a so-called sandwich design, in which the cutout 61 (see Fig. 5 ) in the outer side part 60 (see Fig. 5 ) and the cutout 81 (see Fig. 5 ) in the inner side part 80 (see Fig. 5 ) are missing and replaced by a sandwich insert. The guide rails 340 and 341 remain in the guide area of the slide. The sandwich construction simplifies the production since the side parts no longer have any cutouts and can therefore be processed faster.

Fig. 14b shows the inner side portion 310 with inserted slider 260 (see Fig. 11b ) and operation by the armrest 180 (see Fig. 9b ) and the storage stock 102 (see Fig. 5 ). The section C / D shows the operation by means of armrest 180 (see Fig. 9b ) with inner and outer side part 310 (see Fig. 13b ) and 210 (see Fig. 10b ), Slider 260 (see Fig. 11b ) and the storage stock 102 (see Fig. 5 )). The section C '/ D' shows a so-called sandwich design, in which the cutout 211 (see Fig. 10b ) in the outer side part 210 (see Fig. 10b ) and the cutout 311 (see Fig. 13b ) in the inner side part 310 (see Fig. 13b ) are missing and replaced by a sandwich insert. In the guide region of the slider remain the guide rails 340 and 341, wherein only the guide rail 341 can be seen in section. The sandwich construction simplifies the production because the side parts no longer have cutouts and can therefore be processed faster.

Fig. 14c shows the inner side part 320 with inserted slider 270 (see Fig. 11c ) and operation by the armrest 180 (see Fig. 9b ) and the storage stock 102 (see Fig. 5 ) and the cutout 322 for the freewheel of the gear 194 (see Fig. 9c ) and the pinion 202 (see Fig. 9d ) and the bearing hole 323 for receiving the crankshaft 193 (see Fig. 9c ) or motor shaft 201 (see Fig. 9d ). The section E / F shows the slider 270 (see Fig. 11c ) for actuation by the crank 190 (see Fig. 9c ) and E '/ F' by the motor 200 (see Fig. 9d ). This variant can of course be made in the sandwich construction.

Fig. 14d shows the inner side part 330 with inserted slide 70 (see Fig. 5 ) and operating knob 50/51 (see Fig. 9a ) and the storage stock 102 (see Fig. 5 ) and two externally mounted guide rails 332 and 333 for the slider 70 (see Fig. 5 ). The section G / H shows the lateral actuation by means of the knob 50/51 (see Fig. 9a ) with inner side part 330, slide 70 (see Fig. 5 ), the storage stock 102 (see Fig. 5 ) and the attached guide rails 332 and 333. This variant is a real material and time-saving variant for the production, since the slider is not housed as in the other variants, but is free and you installed only an inner side panel.

Fig. 14e shows the inner side part 510 with inserted slider 270 (see Fig. 11c ) and operation by the hand wheel 480 (see Fig. 9e ) and the gear 482 (see Fig. 9e ) and the cutout 502 for the freewheel of the hub 481 (see Fig. 9e ). The section E "/ F" shows the slider 270 (see Fig. 11c ) for the operation by the hand wheel 480 (see Fig. 9e ). This variant can of course be made in the sandwich construction.

15A shows by way of example the various designs in form and function and application, which may vary depending on the material used. By way of example, a few frame shapes, lying surface designs and bearing designs are shown. The simplest side part / frame shape is the rectangle 350, the 360 rounded form at both ends is just as easy to make. With the 370 mold, there are only two support points and the design with self-locking with a slide becomes a challenge. Ideally, you can use the 380 version with a slide, because the slide is fully enclosed and optically invisible. The variant 390 allows only the use of a lowered foot, but is probably the most aesthetic. The variant 400 in turn has only two support points and is particularly suitable for the installation of wheels. Variant 410 again represents a savings option with externally mounted separate supports, in which, in combination with an external slider, the most cost-effective version can be realized. The variant 420 is probably best suited for execution in metal or plastic, to guarantee the stability of the fragile design.

Fig. 15b shows schematically the different variations of the bearing design. The version 430 shows a roller bearing in which the storage is carried out by a wooden roller. The Version 440 shows a roller bearing that represents an axle with a wheel / roller attached to it, which runs in a guide. Version 450 shows a sliding bearing in which a block is inserted in a guide rail. Version 460 shows the plain bearing used here (simply a wooden rod that glides back and forth on the smoothed surface.) To avoid disturbing noises, it is recommended to either oil, grow, soap, or metal a tread The version 470 shows a journal bearing which, for reasons of stability, will probably only find application in a couch made of metal or plastic.

Fig. 16a FIG. 12 shows the outer side panel 342 with the operating armrest and shortened sliders 344 inserted to accommodate other slimmer forms of the couch such as 390 (see FIG Fig. 15a ) to realize. Also shown is the inner side part 343, in which the ¼-circular cutout 82 (see Fig. 5 ) can be omitted. The section A / B shows the milled version and the section A '/ B' shows the sandwich construction with the intermediate layer 348.

Fig. 16b shows the outer side part 346 with long operating armrest and inserted shortened slide 345. Also shown is the inner side part 347, in which also on the ¼-circular cutout 82 (see Fig. 5 ) can be omitted. The section C / D shows the milled version and the section C '/ D' shows the sandwich design with the intermediate layer 348.

Fig. 16c shows that shows the inner side part 511 with inserted slide 513, push rod 514 and actuated by the round knob 516 by means of the connector 515. The section E / F of Fig. 16c shows the slider 513 and the push stick 103. The section G / H shows the push stick 514, the connector 515 for operation by the knob 516. Again, this variant can be made in the sandwich construction.

Fig. 16d shows the inner side part 522 with slide 518 inserted and actuated by the tooth-handwheel 523 by means of the push stick 519, the corresponding cutout 520 and the cutout 524 for the slide 518. The section G '/ H' of Fig. 16d shows the push stick 519 and the tooth handwheel 523 The cut G / H shows the push stick 514, the connector 515 for the operation by the knob 516. Also, this variant can of course be made in the sandwich construction.

Fig. 17a shows the seat length adjustment, with the two structural seat parts 520 and 531 with the respective guide slots 536 and 537 and the holes 538 and 539 for the guide rods 532 and 533 and the bearing blocks 102 and 103. The two seat parts 530 and 531 have the same shape , but are continuously running against each other and with the guide rods 532 and 533 and the bearing blocks 102 and 103 to a unit 534 (see Fig. 17b) together.

Fig. 17b shows the seat length adjustment 534 as a unit of the above-described items in interaction. The two constructive seat parts 520 and 531 with the respective guide slots 536 and 537 and the holes 538 and 539 for the guide rods 532 and 533 and the bearing blocks 102 and 103. The two gleichgeformten seat parts 530 and 531 are installed in opposite directions and on the guide rods 532 and 533 connected to each other and form with the bearing blocks 102 and 103, the adjustable seat.

Fig. 17c shows the interaction of the frame of back part with storage stock 101, 102, seat parts 530 and 531 with guide slots 536 and 537 and the guide rods 532 and 533 and foot with stock stock 104 in three layers, in which only changes the length of the seat. Likewise, the frame parts of the seats are again shown separately for clarity.

Fig. 18a shows for clarity, the structural seat parts 530 and 531 as individual parts with the respective guide slots 536 and 537 and the holes 538 and 539 for the guide rods 532 and 533 in three different length positions.

Here, the guide slot 536 in the seat portion 530 simultaneously the ramp surface for the Guide rod 532, which also serves as a push rod for the Arretierungsschieber 535, which in turn joins its inner sides by positive friction on the outer sides of the seat surface part 530 to a self-escapement. The seat portion 531 and the guide rod 533 serve as a pure extension of the seat (see Fig. 19 ).

Fig. 19 shows the seat length adjustment by the interaction of the Arretierungsschiebers 535 and the structural seat parts 530 and 531 with guide slots 536 and 537 and the holes 538 and 539 for the guide rods 532 and 533I with the bearing blocks 102 and 103, but in its entirety as a surface. The distances between the individual components are exaggerated, so that the functionality remains recognizable.

Fig. 21b shows the perspective view of the deck chair 600 with the in Fig. 21a detailed parts and their interaction.

Fig. 22a - g shows the side view of the deck chair 600 ( Fig. 21b ) in seven different positions and the interaction of the backrest 606 with the Arretierungsstange 603 the Arretierungsschieber 601 with the rear side support 609 via the pivot bearing 633 with the Lagerstock 645, and the connecting rod 610 for spreading the side supports and the activation of the lifting of the foot part 604 and 640 via the push bar 607 in conjunction with the seat portion 605 and its guide slot 621 on the storage in the front side support 608th

As can be seen from the above explanations, the present invention relates to the stepless adjustability and self-locking of the ergonomic couch (buckling points are on the one hand in the hip area and on the other hand in the knee area and not as in other couches in the back and knee knee bend) due to the intersecting Movement directions of the slider 70 (see Fig. 5 ) (horizontal) and the storage stock 102 (see Fig. 5 ) (¼ circle - or vertical, movable connection between the backrest and seat) block each other. The necessary oblique long hole 72 (see Fig. 5 ) in the slider 70 (see Fig. 5 ) for receiving the storage stock 102 (see Fig. 5 ) and the ¼ circular arc cutout 82 (see Fig. 5 ) for the freewheel of the storage stock 102 (see Fig. 5 ) in the inner side part 80 (see Fig. 5 ) is a prerequisite of this functionality. Likewise, the two cutouts 61 (see Fig. 5 ) and 81 (see Fig. 5 ) on the inner sides of the side parts 60 (see Fig. 5 ) and 80 (see Fig. 5 ) as a guide for the slider 70 (see Fig. 5 ) relevant. For the operation of the slider 70 (see Fig. 5 ) There are three variants. On the one hand by means of the side-mounted knob (consisting of two parts 50 and 51) in the long hole 62 (see Fig. 5 ) of the side part 60 (see Fig. 5 ) freely with the connector 51 (see Fig. 5 ) and on the other hand with the slider 70 (see Fig. 5 ) by means of the slot 72 (see Fig. 5 ) is firmly connected. On the other hand, there is the possibility of vertical operation of the slider 260 (see Fig. 11b ) via the connecting web 262 (see Fig. 11b ) by an armrest 180 (see Fig. 9b ). The operation of the slide 70/260 is always only with relief of the bearing stock 102 (see Fig. 5 ) by means of displacement of the center of gravity (by abdominal muscle tension or relaxation of the user) possible. Or by a motor or manually by means of a crank 190 (see Fig. 9c ) driven pinion 194 (see Fig. 9c ) which the slider 270 (see Fig. 11c ) with a toothing 272 (see Fig. 11c ) is executed at the lower end. This functionality can also by a pure push / push movement of the storage stock 103 on the slider 344, or as in FIG. 16c and 16d be achieved on the slide 513 or slide 518. This applies to the symmetrical self-locking. In asymmetric self-locking movement is only blocked when leaning and not when erecting.

In addition to the correct kink in the hip area, the footrest is also lowered in the present couch in the sitting position and there is another kink in the knee area of the user. This prevents tension and strain on the knee joint. This is achieved by the oblique guide long holes 84 (see Fig. 5 ) in the inner side parts 80 (see Fig. 5 ) and the connection of the backrest 23 (see Fig. 2 ) with the seat surface 24 (see Fig. 2 ) and the foot part 25 (see Fig. 2 ) by means of the bearing blocks 102, 103 and 104 (see Fig. 5 ), on the one hand connect these lying surfaces together and at the same time as a support in the respective guide-long holes 83 (see Fig. 5 ) serve. The pivotal point here is the storage stock 101, which is firmly glued in the back and located in the bearing hole 88 (see Fig. 5 ) in the inner side part 80 (see Fig. 5 ) can turn.

Furthermore, in conventional sunbeds, the bath towel can slip from the backrest when sitting down and must be brought back into position cumbersome. By executing the topmost rung as a loose rod 100 (see Fig. 5 ) of the lying device according to the invention, in the holes 97/137 (see Fig. 5 ) of the two side parts 90/130 (see Fig. 5 ) is freely movable, you can with or without taking out (threading the bath towel) of the round rod 100 (see Fig. 5 ) flip the bath towel and it does not slide down when raising the bed in the sitting position.

The couch according to the invention can be made in various materials such as metal, wood, plastic, ceramics, kraft paper, cardboard and rattan and various shapes, colors and designs. Depending on the material and design, the couch according to the invention, since it works without power, can be used indoors and outdoors.

The side parts or frames of the couch according to the invention are different executable depending on the material and thus have effects on the bearing surfaces (see Fig. 15b ) or the type of slide used (variants see Fig. 15a . Fig. 16c and 16d ) and on the static elements (wood rods round bars 110, 111, 112 or boards), which with the inner side parts 80 (see Fig. 8 ) span a thought triangle.

As in Fig. 8 the loungers with and without rollers are executable and different solutions are shown (without rollers 170, 171 lying on the inside, semi-recessed 172 lying on the inside, semi-recessed 173 lying on the outside, 174 lying on the outside and 175 lying on the outside).

The execution of the bearings depends on the material and can be performed in wood as a simple support or with metal insert (eg brass, self-lubricating), roller bearings, plain bearings or journal bearings. This also applies to the position or orientation of these bearings (see Fig. 15b ).

Also the lying areas (see Fig. 2 ) in rungs design, depending on the material used from simple boards, rungs, pipes, rods, a Covering (including plastic, textiles, leather, wire, paper wrapped wire, ropes, cords or plant fibers) or a grid, a braid, a perforated plate or plates which may also be provided with Aussparrungen exist.

In general, there are two variants of the self-locking wood version. On the one hand the hunched version with side knob (see Fig. 5 , Parts 50 and 51), with armrest 180 (see Fig. 9b ), with crank 190 (see Fig. 9c ) or with engine 200 (see Fig. 9d ) - which in turn is divided into two groups. A milled guide in the side panel and the sandwich construction. On the other hand, the non-chopped version with laterally mounted open guide of the slide 70 (see Fig. 14d ) and the guide rails 332 and 333 (see Fig. 14d ).

In addition, depending on the material used different versions of the frame construction are possible. Once from boards as previously shown, or simple frames made of solid metal, pipes (round, oval, square, square, etc.) or plates, folding material and slats possible.

The present wooden couch is designed so that all connections only with galvanizing, holes are permanently cemented with wood glue. On the one hand, this is very ecological and on the other hand very advantageous for the production process. However, the connections can also be made with screws to realize simpler designs that do without galvanizing. In the case of metal beds, screw-in or welded connections are usefully used anyway.

To increase comfort, the use of a support on the bed surface is attached, either a commercial with fabric, leather or cork covered foam u. o. Latex mat is, or a pad of woven sheep's wool which can be easily attached by means of a Velcro on the back. Of course, the use of a normal bath towel is possible. Similarly, roll pads in the neck-back - or knee area can be used.

Thus, the present invention relates to a reclining device for variably adjusting the position between a substantially horizontal position and a position ergonomic sitting position, like in the FIGS. 1 to 16 shown, wherein the seat length adjustment is not shown, which, however, in the following FIGS. 17 to 22 is shown and explained in detail. It will be readily apparent to those skilled in the art that the seat length adjustment, such as in particular FIG. 17c also shown on the embodiments of the reclining devices of FIGS. 1 to 16 can be transmitted.

There is generally the possibility of symmetrical self-locking with blocking in both directions of movement (with parallel flanks of the slanted slot 71, 261, 271, 281, 291, 301 in the slide 70, 260, 262, 270, 280, 290, 300, 321 , 331, 344, 513, 518) or the asymmetric self-locking with blocking in only one direction of movement with the preferred blocking / sliding direction, which is defined by different angles of the slot 71, 261, 271, 281, 291, 301 in the slider 70 , 260, 262, 270, 280, 290, 300, 321, 331, 344, 513, 518 for push / push direction. That the two flanks of the slot are not parallel, but have different pitch. In blocker direction (leaning against the backrest), a shallow angle is used to set the maximum friction or as required by the application. In the opposite sliding direction (raising from the sitting position), a steep angle is used to set the friction minimally or depending on the application required. This results in an asymmetrical sequence of movements, which allows full braking action (self-locking) in one direction, and maximum sliding in the opposite direction (very little or no self-locking).

As a further improvement of the lying characteristics to conventional couches the variant with the stepless seat length adjustment 534 (see Fig. 17b ) by means of external Arretierungsschiebers 535 (see Fig. 18b ) as in the interaction of these components (see Fig. 18c and Fig. 19 ), the possibility of continuous adaptation to different body sizes (eg a child, a woman, a normal sized man or a very large adult), without having to get up from the couch at all. This is due to the mutual displacement of the seat parts 530 and 531 (see Fig. 18c and Fig. 19 ) by means of the guide slots 536 and 537 in conjunction with the guide rods 532 and 533 which generate infinitely by the Arretierungsschieber 535 self-locking allows. Whereby this works on the same principle as with the internal slider in the side parts of the lounger. By extended slots in the inner side parts of the lounger, it is possible to tolerate this "extension" of the seat without the functionality limit. A prerequisite is in the variant shown here, that the backrest, the seat and the foot are designed by means of longitudinal elements instead of cross struts. Of course, there is also the possibility to combine transverse and longitudinal struts, or surfaces on the backrest and the footrest with the seat length adjustment, in which the connection via the bearing blocks 102 and 103 (see Fig. 18c ) and ensures independent mobility of the seat parts 530 and 531 against the back and foot.

By using the deck chair variant (see Fig. 21b and Fig. 22a-g ) opens up a completely new possibility, the foot part 604 or 640 (see Fig. 21a-b ) in the movement from the sitting position to the lying position by means of a push rod 610 (see Fig. 21a-b ). This is only possible through the interaction of the individual components coordinated with each other. Due to the special shape of the back part 606 (see Fig. 21a ) with the molded lever, the holes for the pivot bearing 624 (see Fig. 21a ) in which the storage stock 645 makes the supporting connection to the rear side supports 609 via the bearing bushing 633, a torque arises when leaning against, which is achieved via the connection to the seat part 605 (see FIG Fig. 21a-b ) via the bore 625 in the back 606 (see Fig. 21a-b ) by means of the stock stock 644 (see Fig. 21a-b ) via the bore 620 in the seat part 605 (see Fig. 21a-b ) transmits as thrust. The seat part 605 (see Fig. 21a-b ) in turn slides with the guide slots 621 (see Fig. 21a-b ) on the guide rod 639 (see Fig. 21a-b ) which in turn in the bearing hole 630 (see Fig. 21a-b ) of the front side support 608 (see Fig. 21a-b ) is fixed. At the same time, the lever of the backrest and the corresponding hole 626 (see Fig. 21a-b ) and connecting pin 646 (see Fig. 21a-b ) by means of the push stick 607 (see Fig. 21a-b ) with hole 628 (see Fig. 21a-b ) in conjunction with the bulge in the foot portion 604 (see Fig. 21a-b ) which are interconnected by the bearing pin 638, the foot parts 604 (see Fig. 21a-b ) and 640 (see Fig. 21a-b ) which via the connecting rod 637 (see Fig. 21a-b ) are connected to each other, raised. To lock the position one uses the locking slide 601 (see Fig. 21a-b ) in conjunction with the locking rod 603 (see Fig. 21a-b ) which with its bearing bush 615 (see Fig. 21a-b ) with the back 606 (see Fig. 21a-b ) via the bearing pin 647 (see Fig. 21a-b ) and by means of the guide slot 624 (see Fig. 21a-b ) by the locking pin 602 (see Fig. 21a-b ) with the two side supports 608 and 609 (see Fig. 21a-b ) is connected by the Arretierungsschieber 601 (see Fig. 21a-b ) firmly against the direction of movement of the Arretierungsstange 603 moves, whereby the Arretierungsschieber 601 (see Fig. 21a-b ) by means of its oblique hole 613 (see Fig. 21a-b ) on the outside with the Locking rod 603 (see Fig. 21a-b ) and the locking pin 602 (see Fig. 21a-b ) and thus generates a "self-inhibition" via a Friction Forming of the components.

The present invention relates to a reclining device for variably adjusting the position between a substantially horizontal position and an ergonomic sitting position having at least a right and a left side part respectively comprising at least one outer side part 60 and one inner side part 80 is constructed, a backrest element 90 and a seat surface element 91 which are rotatably connected to each other via a first storage stock 102, and a foot part element 92 which is connected via a second storage stock 103 with the seat surface element 91 rotatably connected to each other wherein the foot member 92 is supported by a third stocker 104 between the right and left side members, and wherein the first, second and third stockers 102, 103, 104 are each translationally supported in a respective guide in the right and left side members is that the backrest element 90 the Seat element 91 and the foot member 92 are variably adjustable between a substantially horizontal position and an ergonomic sitting position, and wherein the first storage stock 102 via a Arretierungsschieber 70 in a Arretierungsausfräsung 61 in at least one outer side part 60 by self-locking is locked, and wherein the self-escapement via a hand knob by the user can be canceled. This functionality can also by a pure push / push movement of the storage stock 103 on the slider 344, or as in FIG. 16c and 16d In addition, the self-locking in conjunction with specific seat parts 530 and 531 with guide slots 536 and 537 and the guide rods 532 and 533 in conjunction with the locking slide 535 for a continuously variable seating surfaces Length adjustment is applicable, in particular in Figure 18a-c and FIG. 19 shown. By the longitudinal struts and a deck chair variant with self-escapement on the armrests 603 in conjunction with the Arretierungsschieber 601 is possible, which allows over the push bar 610 in conjunction with the specially shaped back portion 606 an increase in the foot part 604 and 640.
