Device for stretching back

Abstract

The device comprises a frame (1, 2) with two opposite pendulum supports (3), the pendulum supports (3) are connected to a cross member profile (17), and a two-part frame is constructed on the cross member profile and has a front frame portion (VR) and a rear frame portion (HR) 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 (8) which projects vertically forward from the cross-member profile (17). The carriage (7) supports guide rollers (23) on both sides, which guide rollers (23) can be inserted into stationary guide profiles (6) which are attached to the frames (1, 2). Due to the geometry of the pivot axis (12) of the swing beam (3) with respect to the guide profiles (6) and the carriage (7) and the guide rollers (23) thereof, the guide rollers (23) are received into the guide profiles (6) by pivoting the two frame parts (VR, HR) forward. These guide rollers (23) are guided in guide profiles (6) such that when the frame parts (VR, HR) and the two-part bed supported by the frame parts are further pivoted, 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 located on the rear frame part can be varied, and the relative distance between the first front bed part and the rear bed part can be varied when the frame parts (VR, HR) and the two-part bed supported by the frame parts (VR, HR) are further pivoted. And a person lying on the two-part bed can realize a stretching effect through the person.

Description

Technical Field

[0001] The present invention relates to a device for independently stretching one's own back. Many people suffer from back pain, and stretching their back on a stretching bed provides them with relief. However, conventional stretching beds are not user-friendly enough and are generally not operable alone, such that a person to be treated cannot effectively use the stretching bed alone but requires a therapist or assistant. Background Art

[0002] WO 2015 / 107458A1 discloses a stretching device for stretching the back. The stretching device includes a bottom plate having a height-adjustable rod, and a couch is mounted at the upper end of the rod. A stretcher is mounted on the height-adjustable rod such that the stretcher can pivot about a horizontal axis. An adjustable restraint device for the upper arm near the armpit is mounted on a padded movable carriage on the head side of the stretcher, and a restraint device with a footrest for the feet is mounted on a padded movable carriage on the foot side of the stretcher. At the foot end of the stretcher, a standing surface is formed at a right angle to the stretcher. Two handrails for manually controlling the inclination of the stretcher are hinged to the front of the upper part of the rod. The padded movable carriages are connected to each other together with the restraint devices on the stretcher by cables, wherein a steel cable is wound around a number of deflection pulleys such that when the stretcher rotates about the horizontal position, the padded carriages can move apart in a coupled manner and, conversely, can move towards each other again. By swinging the couch about its horizontal position, the back can be alternately stretched and relaxed. Although this structure works perfectly, it has proven to be relatively complex, with its various cables and pulleys being heavy, cumbersome, and most importantly, expensive to manufacture. Additionally, it can only be used in an inverted position. Summary of the Invention

[0003] In view of the above prior art, the object of the present invention is to provide a device for stretching the back that is simpler, lighter, more space-saving, and has a simpler design, such that the device can also be manufactured more economically, and the device particularly does not require cables, cable pulleys, and deflection pulleys, and furthermore, the device can be used very easily and comfortably for prone and supine positions and can be variably adjusted for different body positions, and the stretching of the back can be adjusted very precisely by the user himself during use.

[0004] This problem is solved by a device for lying prone or supine and stretching the back, said device comprising a frame having two opposite pendulum supports, the lower ends of said pendulum supports being connected to a transverse member profile, and on said transverse member profile there is mounted a two-part frame comprising a front frame part and a rear frame part for supporting a two-part lying board, said rear frame part being attached to said transverse member profile in a rearwardly projecting manner and carrying a footrest at the rear end thereof, wherein a mechanical guidance and a cordless mechanical connection are provided between said pendulum supports and said two-part frame, by means of which mechanical guidance and said cordless mechanical connection, when said two-part frame swings, the front frame part can be pushed away from and again pushed together with the rear frame part, so that the two parts of the two-part lying board respectively supported by the front frame part and the rear frame part can also be pushed away from and again pushed together with each other for a controlled stretching of the upper body of a person lying on the two-part lying board, wherein said swinging can be effected by the user himself.

[0015] Figure 1Shows the device in the deployed and upright use position as seen from the left side, for prone or supine use. The device comprises frames 1, 2 which carry two opposite pendulum supports 3 on which a two-part frame is suspended, the two-part frame having a front frame part VR and a rear frame part HR, the front frame part VR and the rear frame part HR having frame profiles 4, 5 for supporting the two-part lying board. At the front part VR of the frame and below it, the frame profile 5 is firmly connected to this front part VR of the frame, while in the rear part HR the frame is formed by two frame profiles 4 extending parallel to each other, whereby only one of these two frame profiles 4 is visible in the side view shown here. The rear backrest part can be mounted on these two parallel frame profiles 4 and comprises a board which is padded at the top. In the front part VR of the frame, which is supported by the frame profile 5, the front part VR of the frame is mounted on the frame profile 5 and firmly connected to it. The frame profile 5 passes through the mounting 20 and is firmly anchored in the mounting 20. And this mounting 20 in turn is located on a slide 7 through which a guide 8 is guided such that the slide 7 can move back and forth on the guide 8, whereby the guide 8 projects at right angles from a transverse member profile 17 which firmly connects the two pendulum beams 3 to each other. Finally, the frame profile 5 can thus be shifted slightly forwards or backwards relative to the same guide 8 and thus the entire front frame part VR can also be shifted slightly forwards or backwards relative to the same guide 8, and the front frame part VR can also be pivoted slightly to the left or right about a vertical axis on the carriage 7. The frame for this overall structure is here formed by four supports 1, 2 in the manner of a stepladder, whereby the longer support 1 forms at its upper end a pivot bearing 12 for the downwardly suspended pendulum beam 3. The lower ends of the supports 1, 2 are connected by connecting pipe fittings 15, 16 to the supports 1, 2 on the other side of the device to improve the ground support. The slightly shorter support 2 is hinged to the support 1 at a hinge point which is about a quarter of the length of the support 1 from the top, where a folding hinge 19 is formed. This allows the frame to be folded up like a stepladder and thus can be stored in a space-saving manner. The actual lying board is not shown here and comprises two parts, one being a rear flat lying board part for the pelvis and legs which, as seen from the side, is mounted on the two frame profiles 4 of the rear frame part HR, and one being a front flat lying board part for the chest or back which is attached to the front frame part VR and the distance between this front flat lying board part and the rear lying board part can subsequently be changed by sliding the frame profile 5 along the slide profile 8 on the slide 7 which carries the frame profile 5. These two backrest parts can be provided with padding to facilitate lying comfortably on them, whether lying back on these backrest parts or lying prone. Both use variants are possible.

[0016] At Figure 1In it, the frame parts VR, HR and the reclining part to be installed thereon extend into a reclining structure, and the reclining structure forms an angle of approximately 45° with the ground. However, in order to enter the device, Figure 1 the stretcher in it rotates further clockwise about the axis of rotation 12 of the pendulum support 3 until it is approximately vertical. Subsequently, after entering the device, the stretcher can be rotated from this initial position to a horizontal position and further rotated, which subsequently causes the body lying on it to be stretched, as described below.

[0017] The two pendulum beams 3 are connected to each other at their lower ends by a transverse member profile 17 (not visible here) between two supports 1, 2 on each side. The two rear frame profiles 4 of the rear frame part HR extend above the transverse member profile 17 and are firmly connected to the transverse member profile 17 by two support profiles 34, and the two support profiles stand vertically on the transverse member profile 17, as Figure 4 can be seen. As Figure 2 can be seen, the rear frame part HR extends slightly beyond the transverse member profile 17 at the front. At the front end of the front frame part VR, a holding rod 11 extending transversely to the lying board is installed, and when the user climbs onto or into the device, the holding rod 11 can be grasped by hand. In Figure 1In it, the guide rollers 23 can be seen on the side surface of the carriage 7. There are also guide rollers 23 on the other side of the carriage 7. It can be seen that the guide profile 6 projects laterally from the support 1 approximately at the height of the lower end of the pendulum support 3. There is a similar guide profile 6 on the other side of the device. When the pedestal is rotated beyond the horizontal position, these guide rollers 23 enter the inner sides of the two guide profiles 6 and are guided therein. This causes the carriage 7 to be forced forward on the guide 8 due to the geometry of these components, and when rotated backward, the carriage 7 is correspondingly moved backward on the guide 8. This movement of the carriage 7 is naturally transmitted to the front frame part VR mounted thereon, and the front frame part VR carries the front lying part (not shown here). Therefore, overall, the distance between the front reclining part and the rear reclining part is variable, which causes the user's back to be stretched forward according to the degree to which the reclining structure rotates beyond the horizontal position and can be precisely adjusted. The footrest 10 is attached to the lower end of the rear frame part HR, and slightly above the footrest 10 is the restraint device 9 with two rollers 24, 25 for each leg. The distance between the two rollers 24, 25 can be adjusted for fixing the feet above the ankles. From the area of the roller 24, the two rear frame profiles 4 extend slightly upward in an arc to the pendulum support 3 and slightly beyond the transverse member profile 17, thus overlapping the front frame profile 5, which extends forward from the transverse member profile 17 and extends in the middle of the device. The two rear frame profiles 4 are equipped with rear lying parts, while the front frame part VR is equipped with a lying part for the upper body. Depending on the position of the user, whether the user is lying face down or face up in the bed, the front lying part supports the chest and abdominal areas or the user's back. Starting from the uppermost quarter of the support 1, the armrest 13 first extends backward, then upward, where it bends, then extends downward parallel to the support 1 approximately at the position of the carriage 7, and finally terminates again on the support 1 itself in the lower region of the support 1 and is attached there. There is the same armrest 13 on the other side of the device. These armrests 13 can be coated with a material that is easy to grip, such as sponge rubber or a suitable soft rubber.

[0018] When the user starts from the approximately vertical position of the frame parts VR, HR and stands on the two footrests 10 facing the device, he can grasp the two armrests 13 and start the pivoting of the lying board, and gradually adjust the position of grasping the armrests 13 until he has reached the horizontal position. From then on, he can hold the front support rod 11 and then continue to rotate the stretcher by shifting his weight ( Figure 1In the counterclockwise direction (as viewed from the rear), this causes the front part of the stretcher to move away from the rear part, and when the stretcher is rotated backward, the front and rear parts of the stretcher move back together again. This rocking around the horizontal position allows the user to precisely adjust the stretching force and the amount of stretch. If the user steps onto the footrest 10, leans their back against the device, and then gradually rotates to the horizontal position of the reclining board in a supine position, the whole process proceeds in the same way. Similarly, by holding the support bar 11 or the armrest 13, the user can rock around the horizontal position of the chair, thereby achieving precise adjustment of the stretching of the upper body or the back, making them feel comfortable and at ease.

[0019] In Figure 2 it, the device is viewed from the rear (i.e., relative to Figure 1The view (seen from the right side) shows that it can be seen here that the device has supports 1, 2 on both sides (i.e., the left side and the right side), where only the shorter support 2 can be seen here, and only the uppermost part of the longer support 1 can be seen in each case. Here, at the upper end of the support 1 on the other side, there is a pivot shaft 12, and the downwardly hanging pendulum support 3 is pivotally mounted on this pivot shaft 12 on the inner side of each side of the device, so that the pendulum support can pivot back and forth in a direction perpendicular to the plane of the drawing. The two pendulum supports 3 are connected to each other at their lower ends by a transverse member profile 17. It can be seen that two curved frame profiles 4 extend from the restraint device 9 for the feet, slightly beyond the transverse member profile 17 and to some extent laterally overlap the front frame profile 5. It can be seen that the lower ends of the two pendulum supports 3 are further displaced slightly towards the center of the device by two bends. Above the transverse member profile 17, the pipe fittings 14 lead away from the carriage 7 on both sides to one side, and these pipe fittings 14 are firmly connected to the carriage 7. Each of the pipe fittings 14 has guide rollers 23 at both ends. These guide rollers 23 are respectively located at the ends of the inner pipe, and the inner pipe can be pulled out within the pipe fittings 14. This allows these guide rollers 23 to be pulled out of the pipe fittings 14 and then occupy a position further out than shown here. This is necessary in order to operatively connect these guide rollers 23 to the guide profile 6, which is mounted on the support 1 in the form of a flat U-shaped profile and projects laterally from the support 1, whereby the guide profile 6 faces the center of the device with its open side. When the lying board is rotated, these guide rollers 23 move into these guide profiles 6, and when the lying board is further rotated, these guide rollers 23 are guided along these guide profiles 6, which causes the carriage 7 to be forcibly displaced on the guide 8. Subsequently, the frame 20 and the front frame profile 5 clamped in the frame 20 also move together with the carriage 7. During the rocking motion, the carriage 7 moves forward, and conversely, when swinging backward, the carriage 7 moves backward on the guide 8. However, since the front reclining part is mounted on the front frame part VR and the front frame profile 5, and the front frame profile 5 is in turn located on the carriage 7 together with the mounting member 20, the two frame parts VR and HR ultimately move back and forth relative to each other, that is, the distance between the front frame part VR with its reclining part and the rear frame part HR and its reclining part is variable. At the front end of the front frame part VR, the holding rod 11 can be seen, and at the lower end of the rear frame profile 4, the foot support 10 and the restraint device 9 for the feet can be seen. At the bottom, the connecting pipe fitting 15 for connecting the lower ends of the two supports 2 can be seen.

[0020] Figure 3The figure shows the device as seen from above. Here, the supports 1 and 2 on both sides of the device can be seen. The supports 1 and 2 are connected to each other by a hinge 19 and can be arranged in the manner of a stepladder or folded around the hinge 19 when not in use. The two pivot shafts 12 located at the upper ends of the supports 1 are also visible, and the swing beam 3 is suspended on these two pivot shafts. The ends of the swing beam 3 are slightly offset towards the center of the device and are firmly connected to the transverse member profile 17. Above the transverse member profile 17, two pipe fittings 14 with end guide rollers 23 can also be seen. Thus, these pipe fittings 14 project vertically laterally from the carriage 7 and are firmly connected to the carriage 7. As Figure 1 can be seen, the front frame profile 5 is mounted on the carriage 7 through its mount 20. The front frame part VR is connected above to the front frame profile 5, and the laterally extending holding rod 11 is mounted at the front end of this front frame part VR. Two frame profiles 4 forming the rear frame part HR can be seen protruding forward beyond the transverse member profile 17 and pointing upward in the figure. The rear part of the chair (not shown) is mounted on the rear frame part HR. At the rear end of this rear frame part HR is the footrest part 10. The footrest part 10 has its restraint means 9 for the feet, namely a pair of soft elastic rollers 25 for the area above the heels of a person standing on the footrest part 10, and another pair of soft elastic rollers 24 for the area against the front of the lower leg above the ankles. This top view also shows two connecting pipe fittings 15, 16 for connecting the lower ends of the supports 1 and 2 on both sides of the device.

[0021] Figure 4The structure of the device is further illustrated, and a perspective view slightly inclined from the left front shows the main central part of the device. This view shows the uppermost part of the support member 1 and the rotating shaft 12 at its upper end. These are achieved here by means of bushings into which mating bolts are inserted, and the pendulum beams 3 extending downwardly are suspended from the inner ends of these bolts on both sides of the device. These pendulum beams 3 have two kink portions or bends such that the lower ends of these pendulum beams 3 are offset towards the middle of the device. Here, the pendulum supports 3 on both sides of the device are firmly connected to the transverse member profile 17. As can be seen here, the front end of the rear frame profile 4 of the rear frame portion HR is firmly connected to the support beam 34 which stands on the transverse member profile 17 and is thus also fixed to the pendulum beam 3. The rear part of the front frame profile 5 extends rearwardly between the two support beams 34 and is fixed in the retainer 20. In its rear region, this front frame profile 5 is firmly connected to the front frame portion VR by the connecting profile 35 which stands vertically on the front frame profile 5 and where few connecting profiles can be seen. The frame 20 is pivotally mounted laterally at the top of the carriage 7 which has on its side an attachment pipe member 14 extending perpendicular to the carriage, and each pipe member 14 has at its end a guide roller 23. When the front frame portion VR and the rear frame portion HR rotate about the axis of rotation 12 of the pendulum profile 3, these guide rollers 23 move into the guide profile 6 and are located inside the guide profile 6 and are subsequently guided therein. When the frame portions VR, HR and the reclining portions mounted thereon are pivoted forward, this forced guidance of the guide rollers 23 in the guide profile 6 combined with the geometry of their arrangement causes the front reclining portion to move forward on the front frame portion VR because the carriage 7 slides or rolls forward on the guide 8 connected at right angles to the rear transverse member profile 17 and thus also drives the frame 20 and the front frame profile 5 and the front frame portion VR mounted on the front frame profile 5 and the reclining portion mounted on the front frame portion VR. In this way, the front reclining portion moves forward relative to the rear reclining portion and the person lying on these two reclining portions is stretched, regardless of whether they are lying prone or supine on the reclining portions. When swinging backward, the guide rollers 23 in the guide profile 6 roll forward again and cause the two reclining portions to move towards each other. In this way, first stepping onto the footrest portion 10 in the vertical position of the stretcher and then grasping the armrest 13, they can slowly swing the stretcher forward until it reaches the horizontal position, and then by grasping the transverse support bar 11, they can stretch themselves in a controlled manner by swinging their body more or less forward and control the stretching force by the amount of swing about the axis of rotation 12. When the front reclining portion rotates backward, the front reclining portion returns to its initial distance from the rear reclining portion. The pedestal can be rotated back to the vertical position where it is easy to leave the device.

[0022] Figure 5Details of the pendulum beam 3 are shown, which is hinged at the top to the pivot shaft 12 at the upper end of the support 1, and due to two bending points 21, 22, the lower end of the pendulum beam 3 is slightly offset towards the center of the device. At the lower end of the pendulum support 3, the transverse member profile 17 is firmly connected to the pendulum support 3, and the transverse member profile 17 is here in the form of a square steel profile. Above the support profile 17, a pipe fitting 14 and its end guide roller 23 on the side wall of the carriage 7 can be seen, and the end guide roller 23 is located on an inner pipe that can be pulled out of the pipe fitting 14. To prevent the inner pipe from falling out of the pipe fitting 14, the pipe fitting 14 has an elongated hole 26 on the side, and the inner pipe has a cam 27 at that place, so that the inner pipe can only move back and forth in the elongated hole 26 through its cam 27. However, the inner pipe can be fixed in any position by a radial flat head screw 28 with a handwheel 29.

[0023] Figure 6 The situation when the inner pipe 30 and its end guide roller 23 are pulled out of the pipe fitting 14 is shown. In this position, by pivoting the lying board, the guide roller 23 is received into the associated guide profile 6 on the support 1, as shown by the arrow, and then must forcibly follow the guide profile 6. This results in a relative movement of the pipe fitting 14 and the carriage 7 on the guide 8, and the guide 8 is connected to the transverse member profile 17. The pipe fitting 14 is attached to the carriage 7 on both sides and extends vertically from the carriage 7. Therefore, the carriage 7, together with the front frame profile 5 and the front frame part VR, moves back and forth on the guide 8 according to the forward pivot of the lying board. Thus, the distance between the front lying part on the front frame part VR and the rear lying part on the rear frame part HR with its two rear frame profiles 4 can be changed in a controlled manner.

[0024] In Figure 7 and Figure 8 one can see how the whole structure finally works, Figure 7 and Figure 8 shows the central part around the rotation axis 12 of the device seen from the side. First, Figure 7Shows the situation when the lying board has been rotated to the horizontal position. Here, the distance d between the front end of the guide 8 and the slider 7 that can move on the guide 8 is relatively large. It can be seen that the guide 8 has an elongated hole 36, and the transverse bolt 18 on the carriage 7 passes through this elongated hole 36 to achieve its guidance on the guide 8. The front frame part VR is installed above the front frame profile 5 and fixed to the front frame profile 5, and the front frame profile 5 is located on the carriage 7. The mounting member 20 of the front frame profile 5 can pivot laterally. This ensures that a person lying on the stretcher can swing their upper body left and right outward relative to the legs around the vertical axis on the carriage 7 by holding the armrest 11. In order to adjust the position of the armrest 11 for taller or shorter people, the armrest 11 is connected to the front frame profile 5 at the front by an angle steel 31, that is, connected to the front end of the inner profile 38. The inner profile 38 can be pulled forward from the frame profile 5 and can be locked in several pulled-out positions within the frame part 5 by a spring-preloaded cross pin 32, and the cross pin 32 has a gripping ball 33 at the end. This allows the device and its reclining structure to adapt to the different body sizes of users, so that anyone can reach out their arm to grab the support rod 11 when lying on it.

[0025] If the inner tube 30 in the pipe fitting 14 is not extended, the guide roller 23 does not engage in the guide profile 6. In this case, the lying board can be rotated around the rotation axis 12 of the pendulum support 3 as needed. The distance between the front and rear parts of the stretcher always remains unchanged. However, if the inner tube 30 is extended and locked in the extended position by the flat head screw 28 and its handwheel 29, the following will occur when the stretcher rotates counterclockwise in the Figure 8 shown direction: The guide roller 23 moves into the guide profile 6, and when continuing to rotate, the guide roller 23 is forcibly guided along the inner side of these guide profiles 6. This causes the carriage 7 to move relative to the stationary rear frame part 4. The guide roller 23 is connected to the carriage 7 by the pipe fittings 14 extending from both sides of the carriage. As a result, the carriage 7 is displaced forward on the guide 8, and correspondingly, the front frame profile 5 carried by it and the front frame part VR (the reclining part not shown is installed on it) installed on the front frame profile 5 also move forward. The bolt 18 on the carriage 7 engages in the slot hole 36 on the guide 8, and the bolt 18 moves from the Figure 7 shown position to the Figure 8 shown position. At the Figure 8 shown position, the carriage 7 has almost moved to the front end of the guide 8. Therefore, the distance d from the rear frame part HR to the front frame part VR increases, as shown in Figure 7 and Figure 8As shown by the distance arrow in the figure. The two independent parts of the lying board installed on the frame parts VR and HR also move. Therefore, the front part moves away from the rear part of the reclining structure. And when the reclining structure swings backward again, the distance d decreases again. This means that by rocking the chair back and forth, the user can precisely adjust the stretching of their upper body by themselves, regardless of whether they are lying prone or supine.
