Stretching device for stretching the back

Abstract

The device consists of a framework (1, 2) with two opposite swinging beams (3), which are connected to a cross-member profile (17), and on which a two-part frame with a front frame part (VR) and a rear frame part (HR) is constructed for supporting a two-part bed. The front frame part (VR) is fastened to a carriage (7), which is guided in a longitudinally displaceable manner on a guide profile (8), which projects vertically forwards from the cross-member profile (17). This carriage (7) supports guide rollers (23) on both sides, which can be inserted into stationary guide profiles (6) attached to the framework (1, 2). Due to the geometry of the pivot axis (12) of the swinging beams (3) with respect to these guide profiles (6) and the carriage (7) and its guide rollers (23), these guide rollers (23) are retracted into the guide profiles (6) by pivoting the two frame parts (VR, HR) forward. They are guided therein, so that when the frame parts (VR, HR) and the two-part bed they support are pivoted further, the relative distance between the first front bed part on the front frame part (VR) and the rear frame part (4) and the rear bed part lying thereon can be varied, and a stretching action can be applied to the person lying on the two-part bed by him / herself.

Description

Device for stretching the back

[0001] The invention relates to a device for independently stretching one's own back. Many people suffer from back pain, and stretching their back on a traction bed brings them relief. However, conventional traction beds are not user-friendly enough and are often not operable alone, meaning that a person undergoing treatment cannot effectively use the traction bed on their own; instead, a therapist or assistant is required.

[0002] A traction device for back extension is known from WO 2015 / 107458 A1. This traction device consists of a base plate with a height-adjustable mast on which a table is mounted at the top. The table is pivotally mounted on this height-adjustable mast about a horizontal axis. Adjustable restraints for the upper arms are attached to a sliding carriage with padding at the head end of the table, and restraints with foot pads are attached to a sliding carriage with padding at the foot end of the table. A standing surface perpendicular to the table is formed at the foot end. Two handles for manually pivoting the table are hinged to the front of the upper mast section.The sliding sleds with the cushions, along with the restraint devices, are connected to each other on the couch by means of a steel cable around several pulleys, such that by pivoting the couch around its horizontal position, the sleds with the cushions can be moved apart in a coupled manner and, conversely, back towards each other. This is achieved by rocking the couch around its horizontal position. The back can be alternately stretched and relieved. While this design functions perfectly, it proves to be relatively complex and complicated in its construction, with its various cables and pulleys; it is heavy, bulky, and above all, expensive to manufacture. Furthermore, it can only be used while lying face down.

[0003] In view of this state of the art, the object of the present invention is to provide a device for stretching the back which is simpler, lighter, more space-saving and less complex in design, so that it can also be manufactured more cost-effectively, and which in particular does not require cables, pulleys and deflection pulleys, and which is furthermore extremely easy and comfortable to use both in a prone and supine position, as well as being variably adjustable for different body sizes, and by means of which the stretching of the back can be very finely dosed by the user himself during application.

[0004] The task is solved by a device for lying on one's stomach or back and stretching the back, consisting of a frame with two opposing pendulum supports attached to it, the lower ends of which are connected by a crossbeam profile, and on which crossbeam profile a two-part frame consisting of a front frame part and a rear frame part for supporting a two-part couch is mounted, wherein the rear frame part is attached to the crossbeam profile projecting backwards and carries footrests at its rear end, wherein a mechanical guide and mechanical ropeless coupling is provided between the pendulum supports and the two-part frame, by means of which a pendulum movement of the two-part frame makes it possible to push apart and push together the front frame part relative to the rear frame part and the parts of the two-part couch that they support.for the controlled stretching of the upper body of a person lying on the two-part couch, whereby this pendulum movement can be effected by the person themselves.

[0005] The drawings show this device and its individual parts, which are subsequently described, and the function of the device is also explained and illustrated. It shows: Fig. 1: The device in its unfolded and erected operating position, viewed from the side; Fig. 2: This device seen from the rear, that is, viewed from the right in relation to Figure 1; Fig. 3: This device seen from above; Fig. 4: The central part of this device in a perspective view from the front and from the left side looking obliquely backwards; Fig. 5: A tube connected to the slide on the rear frame part for the extendable guide rollers, with the guide roller retracted; Fig. 6: This tube according to Figure 5 for the extendable guide roller, with the guide roller extended; Fig. 7: The central part of the device seen from the left side, with horizontally running frame parts; Fig. 8: This central part of the device according to Figure 7 seen from the left side, with frame parts pivoted forward beyond the horizontal or here in a counterclockwise direction.

[0006] Figure 1 shows the device in its unfolded and erected position for use, viewed from the left side, for lying on in a prone or supine position. The device consists of a frame 1, 2 with two opposing pendulum supports 3, from which a two-part frame with a front frame part VR and a rear frame part HR with frame profiles 4, 5 is suspended for supporting a two-part couch. The front part VR of the frame Below this, the frame profile 5 is firmly connected to the front part VR of the frame, while the rear part HR of the frame is formed by two parallel frame profiles 4, of which only one is visible in the side view shown here. The rear section of the bed, consisting of a padded board, can be mounted onto these two parallel frame profiles 4. The front part VR of the frame is supported by the frame profile 5, upon which the front part VR of the frame is built and to which it is firmly connected. The frame profile 5 passes through a recess 20 in which it is firmly anchored.This mounting 20 is itself pivotally mounted on a slide 7, through which a guide profile 8 is guided, so that the slide 7 can be moved forwards and backwards a short distance on the same slide. This guide profile 8 projects at a right angle from a crossbeam profile 17, which rigidly connects the two pendulum supports 3. Ultimately, the frame profile 5 can thus be moved forwards or backwards relative to the guide profile 8, and consequently, the entire front frame section VR can also be moved. This front frame section VR can also be pivoted to the left and right about a vertical axis on the slide 7. The frame for this entire construction is formed here by four supports 1, 2 in the manner of a trestle ladder, with a longer support 1 forming a pivot bearing 12 at its upper end for each downward-hanging pendulum support 3.The supports 1 and 2 are connected at their lower ends via connecting tubes 15 and 16 to the supports 1 and 2 on the opposite side of the device to improve their contact with the ground. Approximately one-quarter of the length of support 1 is the slightly shorter support 2, which is hinged to it at the top, forming a folding hinge 19. This allows the frame to be folded, similar to a stepladder, for space-saving storage. The actual lying surface is not shown here and consists of two parts: a rear, flat lying surface for the pelvis and legs, which is mounted on the two frame profiles 4 of the rear frame section HR (viewed from the side); and a front, flat lying surface for the chest or back, which is attached to the front frame section VR. The distance between the front and rear lying surfaces can be adjusted by moving the supporting frame profile 5 on the slide 7. Sliding profile 8 is adjustable. These two lying sections can be padded to promote comfortable lying, whether lying on one's back or stomach. Both usage options are possible.

[0007] In Figure 1, the frame parts VR, HR, and the lying sections to be mounted on them form a bed at approximately a 45° angle to the floor. However, to enter the device, the bed in Figure 1 is pivoted clockwise around the pivot axis 12 of the pendulum supports 3 until it is nearly vertical. From this initial position, the bed can then be pivoted into a horizontal position after the user has entered the device, and further pivoted, which then stretches the body lying on it, as described below.

[0008] The two pendulum supports 3 are connected at their lower ends between the two supports 1, 2 on each side by a crossbeam profile 17 (not visible here). The two rear frame profiles 4 of the rear frame section HR extend over this crossbeam profile 17 and are firmly connected to it by two support profiles 34 perpendicular to this crossbeam profile 17, as can be seen in Figure 4. The rear frame section HR extends a short distance beyond this crossbeam profile 17 at the front, as can be seen in Figure 2. A handrail 11 is mounted transversely to the bed at the front end of the front frame section VR, which the user can grasp when climbing onto or entering the device. A guide roller 23 can be seen on the side of the carriage 7 in Figure 1. There is also a guide roller 23 on the opposite side of the carriage 7.Projecting transversely from support 1, a guide profile 6 can be seen approximately at the level of the lower end of the pendulum supports 3. An identical guide profile 6 is present on the other side of the device. When the couch is swiveled beyond the horizontal position, these guide rollers 23 enter the inner surfaces of these two guide profiles 6 and are guided within them. This causes the carriage 7 to be forcibly moved forward on the guide profile 8 due to the geometry of the parts, and when swiveling back, the... Slide 7 is returned to its original position on the guide profile 8. This movement of slide 7 is naturally transmitted to the front frame section VR mounted on it, which supports the front reclining section (not shown here). Thus, the distance between the front and rear reclining sections is varied, which allows for precise forward extension of the user's back, depending on the degree of rotation of the reclining section beyond the horizontal. Footrests 10 are attached to the lower end of the rear frame section HR, and slightly above these are restraints 9, each with two rollers 24, 25 for each leg. The distance between these rollers can be adjusted to secure the feet above the ankles.From the area of ​​roller 24, the two rear frame profiles 4 extend in a slightly upward curve as an arc to the pendulum supports 3 and slightly beyond the crossbeam profile 17, thus laterally overlapping the single front frame profile 5, which extends forward from the crossbeam profile 17 and runs along the center of the device. The two rear frame profiles 4 are fitted with the rear, flat lying section, while the front frame section VR is fitted with a flat lying section for the upper body. Depending on the user's position, whether lying prone or supine, this front lying section supports the user's chest and abdomen or back.From the uppermost quarter of the support 1, a handle 13 extends first backward, then upward, where it curves and, beyond this curve, runs parallel to the support 1, approximately at the location of the slide 7, downward, finally ending at the support 1 itself in its lower region and being attached there. An identical handle 13 is located on the other side of the device. These handles 13 can be coated with a grip-friendly material, for example, with foam rubber or a suitable soft rubber.

[0009] When a user, starting from the approximately vertical position of frame parts VR and HR, stands on the two footrests 10 facing the device, they can grasp the two handles 13 and initiate the swiveling of the couch, gradually adjusting their grip on the handles 13 until they reach a horizontal position. From then on, they can grasp the front support bar 11 and subsequently continue by shifting their weight, as shown in Figure 1. By rotating the device counterclockwise, the lounger is moved away from the rear section, and then back together again. This rocking motion around the horizontal position allows the user to precisely adjust the stretching force and range of motion to their individual needs. The same principle applies when the user, facing away from the device, steps onto the footrests 10 and then gradually tilts back into a horizontal position. Again, by holding onto the support bar 11 or the handles 13, they can rock the lounger around its horizontal position, thus achieving a finely controlled stretch of the upper body and back, precisely as they find comfortable and beneficial.

[0010] Figure 2 shows this device in a rear view, that is, viewed from the right in relation to Figure 1. It can be seen that the device has supports 1 and 2 on both sides, i.e., left and right. Only the shorter supports 2 are visible here, and only the uppermost section of each of the longer supports 1. At the upper ends of the supports 1 on the far side, there are pivot axes 12. On each side of the device, a downward-hanging pendulum beam 3 is pivotally mounted on these axes on the inside, allowing it to pivot back and forth in a direction perpendicular to the plane of the drawing. The two pendulum beams 3 are connected to each other at their lower ends by a crossbeam profile 17. As can be seen, the two arcuate frame profiles 4 extend from the foot retainers 9 slightly beyond the crossbeam profile 17 and overlap the front frame profile 5 laterally to a certain extent.As can be seen, the two pendulum supports 3 are shifted slightly towards the center of the device by two bends. Above the crossbeam profile 17, a tube 14 extends laterally away from the carriage 7 on both sides, and these tubes 14 are rigidly connected to the carriage 7. Each tube carries a guide roller 23 at its end. These guide rollers 23 are located at the end of an extendable inner tube within the tube 14. This allows them to be pulled out of the tube 14 and positioned one position further outwards than shown here. This is necessary to bring them into operative contact with the guide profiles 6, which are mounted here as flat U-profiles on the supports 1 and project transversely from them. These guide profiles 6 are oriented with their open sides towards the center of the device. When the couch is swiveled, these guide rollers 23 move into these guide profiles 6 and, with further swiveling, are guided along these guide profiles 6, which causes the carriage 7 to move along the guide profile 8. The carriage 7 then also moves the socket 20 and the front frame profile 5 clamped within it. When the couch is tilted, it moves forward, and conversely, when it is swiveled back, the carriage 7 moves back along the guide profile 8. Because the front couch section is mounted on this front frame section VR and the front frame profile 5, which in turn sits on the carriage 7 with the socket 20, the two frame sections VR and HR are ultimately moved back and forth relative to each other. That is, the distance between the front frame section VR with its couch section and the rear frame section HR and its couch section is varied.At the front end of the front frame section VR, the support rod 11 can be seen, and at the lower end of the rear frame profiles 4, the footrests 10 and the foot restraints 9 are visible. At the very bottom, the connecting tube 15 for joining the lower ends of the two supports 2 can be seen.

[0011] Figure 3 shows the device in a top view. Here, the supports 1 and 2 on each side of the device are visible. These supports are connected to each other by hinges 19 and can be set up like a stepladder or folded together around the hinges 19 when not in use. Also visible are the two pivot axes 12 at the upper end of the supports 1, from which the pendulum supports 3 are suspended. The ends of the pendulum supports 3 are offset slightly towards the center of the device and are rigidly connected to a crossbeam profile 17. Above the crossbeam profile 17, the two tubes 14 with their end guide rollers 23 are also visible. These tubes 14 extend laterally and perpendicularly from the carriage 7 and are rigidly connected to it.The front frame profile 5 is mounted on the slide 7 with its socket 20, as can be seen in Figure 1. The front frame part VR is connected to the 5 above the frame profile 5, and the support bar 11, which runs transversely to the front of this front frame part VR, is mounted at its front end. It projects forward beyond the crossbeam profile 17, pointing upwards in the image. The two frame profiles 4, which form the rear frame section HR, are visible. The rear part of the unshown lounger is mounted on this frame. At the rear end of this rear frame section HR are the footrests 10 with their foot restraints 9, namely a pair of soft elastic rollers 25 for the area above the heels of the person standing on the footrests 10, and another pair of soft elastic rollers 24 for conforming to the area at the front of the lower legs, above the ankles. This top view also shows the two connecting tubes 15 and 16 for connecting the lower ends of the supports 1 and 2 on both sides of the device.

[0012] Figure 4 further illustrates the construction and shows the main central section of this device in a perspective view from the front left, viewed at a slight oblique angle. This illustration shows the uppermost sections of the supports 1 and the pivot axes 12 at their upper ends. These are implemented here with bushings in which suitable bolts are inserted, and the downward-projecting pendulum supports 3 are suspended from the inner ends of these bolts on both sides of the device. These pendulum supports 3 have two kinks or bends, so that their lower ends are offset towards the center of the device. There, the pendulum supports 3 of both sides of the device are rigidly connected to a crossbeam profile 17. As can be seen here, the front ends of the rear frame profiles 4 of the rear frame section HR are rigidly connected to the support beams 34, which rest on the crossbeam profile 17 and are therefore also fixedly mounted to the pendulum supports 3.The front frame profile 5 extends with its rear portion through the two support beams 34 to the rear and is held in the socket 20. In its rear section, this front frame profile 5 is firmly connected to the front frame section VR via the connecting profile 35, of which only a small portion is visible here. The socket 20 is mounted on top of the slide 7 so as to pivot laterally. The slide 7 has attached tubes 14 running perpendicular to its sides, each carrying a guide roller 23 at its end. When the front frame section VR and the rear frame section HR pivot about the pivot axis 12 of the pendulum profiles 3, these guide rollers 23 run on the inside of the... Guide profiles 6 and are subsequently guided within them. This forced guidance of the guide rollers 23 in the guide profiles 6, in conjunction with the geometry of their arrangement, causes the front lying section to shift forward on the front frame section VR when the frame parts VR, HR, and the lying sections mounted on them are pivoted forward. This occurs as the carriage 7 slides or rolls forward on the guide profile 8, which is connected at a right angle to the cross member profile 17 at the rear, thereby also carrying the socket 20 and thus the front frame profile 5, as well as the front frame section VR and the lying section mounted on it. Thus, the front lying section shifts forward relative to the rear lying section, stretching out a person lying on these two lying sections, regardless of whether they are lying prone or supine.As the chair pivots back, the guide rollers 23 roll forward again in the guide profiles 6, causing the two sections of the chair to move towards each other. This allows a person who initially steps onto the footrests 10 while the chair is in a vertical position and then holds onto the handles 13, to slowly pivot the chair forward until it reaches a horizontal position. They can then stretch by grasping the transverse support bar 11 and rocking their body forward to a controlled degree, adjusting the stretching force by the amount of rocking around the pivot axis 12. As the chair pivots back, the front section returns to its original distance from the rear section. The chair can then be pivoted back into a vertical position, allowing for comfortable dismounting.

[0013] Figure 5 shows a detail of a pendulum support 3, as it is hinged at the top of the pivot axis 12 at the upper end of the support 1, and whose lower end is slightly offset towards the center of the device thanks to the two bends 21, 22. The crossbeam profile 17, here in the form of a square steel profile, is located at the lower end of the pendulum support 3 and is firmly connected to it. Above the support profile 17, a tube 14 can be seen on the side wall of the carriage 7 with its end guide roller 23, which sits on an inner tube that can be pulled out of the tube 14. To prevent the inner tube from falling out of the tube 14, the tube 14 has a slot 26 on its side. The figure shows a cam 27, so that the inner tube with its cam 27 can only be moved back and forth within the elongated hole 26. In any position, however, it can be secured by means of a radial threaded pin 28 with handwheel 29.

[0014] Figure 6 shows the situation when the inner tube 30, with its end guide roller 23, is pulled out of the tube 14. In this position, it is retracted into the corresponding guide profile 6 on the support 1 by pivoting the couch, as indicated by the arrow, and must then follow it. This causes a relative movement of the tube 14 and thus of the slide 7 on the guide profile 8, which is connected to the crossbeam profile 17. The tube 14 is attached to the slide 7 on both sides and projects orthogonally from it. The slide 7, together with the front frame profile 5 and front frame section VR, therefore moves forwards and backwards on the guide profile 8, according to the forward pivot of the couch. The distance between the front couch section on the front frame section VR, on the one hand, and the rear couch section on the rear frame section HR with its two rear frame profiles 4, on the other, can therefore be varied in a controlled manner.

[0015] The overall function of the construction is further illustrated by Figures 7 and 8, which depict the central section about the pivot axes 12 of the device from the side. Figure 7 shows the situation when the couch has already been pivoted into the horizontal position. The distance d between the front end of the guide profile 8 and the sliding carriage 7 is relatively large here. As can be seen, the guide profile 8 has an elongated hole 36 through which a transverse bolt 18 on the carriage 7 passes, guiding it on the guide profile 8. The front frame section VR is mounted above the front frame profile 5 and is stationary relative to it. The front frame profile 5 is pivotably mounted laterally on the carriage 7 by its socket 20. This ensures that a person lying on the couch can pivot their upper body to the left and right around the vertical axis on the carriage 7 by holding onto the handle 11, relative to their legs.In order to adjust the position of the support bar 11 for people of different heights, it is connected at the front to the angle steel 31 with the front frame profile 5, i.e., with the front end. an inner profile 38, which can be extended forward from the frame profile 5 and locked in several extended positions inside the frame part 5 by means of the spring-loaded cross pin 32 with the grip ball 33 at its end. This allows the device and its lounger to be adapted to different body sizes of users, so that everyone can grasp the support bar 11 with outstretched arms while lying on it.

[0016] If the inner tubes 30 in the tube 14 are not extended, the guide rollers 23 do not engage in the guide profiles 6. In this case, the couch can be pivoted freely about the pivot axis 12 of the pendulum supports 3. The distance between the front and rear sections of the couch then remains constant. However, if the inner tubes 30 are extended and locked in the extended position with the threaded pins 28 and their handwheels 29, the following occurs when the couch is pivoted, in Figure 8 in a counterclockwise direction: The guide rollers 23 move into the guide profiles 6, and during further pivoting, they are forcibly guided along the inside of these guide profiles 6. This results in a relative movement of the carriage 7, to which the guide rollers 23 are connected via the tubes 14 projecting from it on both sides, with respect to the stationary rear frame section 4.As a result, the carriage 7 is moved forward on the guide profile 8, and consequently, so are the front frame profile 5 it supports and the front frame section VR mounted on it, along with the reclining section mounted on it (not shown). The bolts 18 on the carriage 7, which engage in the elongated hole 36 on the guide profile 8, move from the position shown in Figure 7 to the position shown in Figure 8. There, the carriage 7 has moved almost to the front end of the guide profile 8. Accordingly, the distance d between the rear frame section HR and the front frame section VR increases, as indicated by the distance arrows in Figures 7 and 8. The two separate sections of the reclining section, mounted on the frame sections VR and HR, also move. The front section thus moves away from the rear reclining section. And when the reclining section is swung back into its original position, the distance d decreases again.This means that by rocking the lounger back and forth, the user can finely control the extension of their upper body. regardless of whether he is lying on his stomach or on his back.

Device according to one of the preceding claims, characterized in that the rear frame part (HR) and the front frame part (VR) each carry a flat lying part on the upper side of a padding, so that the distance between these two longitudinal sections of the couch can be varied when the frame parts (HR, VR) are pivoted about the pivot axis (12) of the pendulum supports (3).Device according to one of the preceding claims, characterized in that the frame is a frame which can be folded about a folding axis (19) in the manner of a trestle ladder, with longer supports (1) on one side of the folding axis (19) and shorter supports (2) opposite the folding axis (19), wherein the shorter supports (2) in the unfolded and erected state of the frame run less steeply than the longer supports (1), to which the shorter supports (2) are articulated with their ends in the upper region of a quarter below their upper end of the longer supports (1), so that the folding axis (19) is formed there, while the pendulum supports (3) are articulated in a pendulum-like manner, hanging downwards, on the pivot axes (12) at the upper end of the longer supports (1).Device according to one of claims 2 to 8, characterized in that the lower ends of the two hanging pendulum supports (3) are connected to a cross member profile (17) connecting them, and the two rear frame profiles (4) are mounted transversely and centrally above this cross member profile (17) and resting on it, which form the rear frame part (HR), and the cross member profile (17) carries the guide profile (8) projecting forwards on it, on which the carriage (7) is guided so as to be longitudinally displaceable by means of bolts (18) in elongated holes (36) in this section of the guide profile (8), wherein the. AMENDED SHEET (ARTICLE 19) front frame profile (5) is built on this carriage (7) and extends forwards and an inner profile (31) is mounted in it so as to be longitudinally displaceable, which is connected at the front end to the front frame part (VR) and the holding rod (11), wherein the inner profile can be locked in several pull-out positions relative to the front frame profile (5) by means of a spring-loaded pin (32) with a grip ball (33), in order to adjust the holding rod (11) to the body size of the persons using the device.Device according to one of claims 2 to 9, characterized in that the displaceable carriage (7) is equipped on both sides with tubes (14) projecting transversely from it, with end-side guide rollers (23) which are held at the outer ends by inner tubes (30) which can be extended in the axial direction from the tubes (14) and can be locked in the extended state and which only in this state move into the guide profiles (6) and are then guided therein, so that when the guide rollers (23) are not extended, the pivoting of the bed about the pivot axis (12) does not cause any variation in the distance between its front frame part (VR) and the rear frame part (HR).Device according to one of the preceding claims, characterized in that the frame is a frame which can be folded about a folding axis (19) and has two supports (1) on both sides and two shorter supports (2) hinged thereto in the manner of a stepladder, the lower ends of the two supports (1) on the one hand and of the two supports (2) on the other hand each being connected to a connecting tube (15, 16) for improved stabilization of the support and the frame. AMENDED SHEET (ARTICLE 19) DECLARATION REFERRED TO IN ARTICLE 19 (1 ) D1: US 10 695 254 B2 (EXPECTATIONS LLC [US]) shows, as the closest prior art, a couch hinged to a frame for lying on. Due to the shape of the couch, as shown in Figure 11, it can be seen that it is intended for a person to lie on their back. Number 205 in Figure 8 of D1 shows a pillow as a headrest. It is clear that this is intended for the back of the head and certainly not for the face. The couch according to D1, with the person lying on their back on it, can be tilted so far beyond the horizontal that the head is then at the bottom and the feet at the top, i.e. the body is in an inverted position, held by the footrest. This inverted position stretches the body and in particular the back.In the device according to this present application, however, the person does not lie on their back but on their stomach on the couch, unlike in D1, and the extension of the back is not brought about by an inverted position of the body but by a displacement of the front part of the couch towards the rear part of the couch, i.e. by moving them apart, and this is brought about by the inclination and pivoting of the couch on the frame. By pivoting back, the two parts of the couch are moved back towards each other. Regarding the longitudinal variation of the couch according to D1, column 6, line 24 simply states: In this regard, the upper end of the extension 21 slides or telescopes within the rod 207 and is selectively locked by a spring-loaded pin or piston arrangement 221 which is inserted through a hole in the rod 207 and an aligned hole 212 in the extension 21.But D1 is only concerned with moving the two parts of the couch against each other and then locking and securing them in a relative position suitable for the user's height. It is therefore only about adjusting the couch to the user's height. However, during operation, when someone is lying on the couch, the two parts are definitely not moved against each other, and certainly not actively moved apart depending on the inclination or by pivoting the couch, to stretch the back, and then moved back together when pivoting back to relieve pressure, which is precisely the special feature of the device according to this application! As requested in the written opinion, the amended patent claim 1 is presented here in a new two-part form.
