[0035] In related art, support assemblies used for lower limb rehabilitation training, particularly those used in bedside rehabilitation scenarios, require the patient to lie on a bed, with their feet and legs supported and guided by the support assembly during exercise. Furthermore, to accommodate users of varying leg lengths, an adjustment assembly is provided between the leg and foot rests to adjust the distance between them. However, these adjustment assemblies are difficult and inconvenient to operate, and the support assembly suffers from poor stability during operation.
[0036] In view of this, the present disclosure provides a support assembly for rehabilitation training. The support assembly for rehabilitation training disclosed in the present disclosure is convenient to operate when adjusting the distance between the foot rest and the leg rest, has low operating difficulty and high operating efficiency.
[0037] Figure 1 Schematic diagram of the structure of the support assembly for rehabilitation training according to the embodiment of the present disclosure. Figure 1 The support assembly for rehabilitation training includes a foot support 10, a leg support 20 and an adjustment assembly 30.
[0038] The footrest 10 is used to support the patient's feet. The legrest 20 is provided at the rear of the footrest 10 to support the patient's feet. The adjustment assembly 30 is used to adjust the spacing distance between the legrest 20 and the footrest 10, so that the support assembly can be suitable for different people with different leg lengths. It is worth mentioning that the footrest 10 and the legrest 20 of the embodiment of the present disclosure can play the corresponding supporting function, and there are multiple options for their structure. For example, two support plates with a relatively simple structure can be selected, or a plurality of support plates with a relatively simple structure can be selected. Figure 1 The footrest and legrest shown in the figure can respectively wrap the patient's legs and feet. The present disclosure does not impose any specific limitation on the structures of the footrest 10 and the legrest 20.
[0039] Figure 2 Schematic diagram of the exploded view of the adjustment assembly of the present disclosure. Figure 2 The adjustment assembly 30 includes a sliding fitting 31, a sliding member 32 and an operating member 33. The side wall of the sliding fitting 31 is provided with a locking portion 312.
[0040] Figure 3 is a top view of the sliding member and the operating member of the embodiment of the present disclosure. Figure 2 and Figure 3 The sliding member 32 can be relatively slidably combined with the sliding matching member 31.
[0041] Optionally, the sliding fitting member 31 is formed with a first sliding groove 3101, and the sliding member 32 is formed with a sliding portion 321 that slides with the first sliding groove 3101. The sliding portion 321 can be formed by extending downward from the sliding member 32 and slidably disposed within the first sliding groove 3101, thereby slidingly engaging with the first sliding groove 3101. Optionally, there can be one or more sliding portions 321, for example, there can be two sliding portions 321, and the two sliding portions 321 are disposed on the sliding member 32 and located at opposite ends of the sliding member 32.
[0042] One of the sliding member 31 and the sliding member 32 is connected to the footrest 10, and the other is connected to the legrest 20. Therefore, when the sliding member 32 slides along the sliding member 31, one of the legrest 20 and the footrest 10 moves accordingly with the movement of the sliding member 32, while the other remains stationary accordingly with the movement of the sliding member 31. As a result, the distance between the footrest 10 and the legrest 20 changes, thereby adjusting the distance between the legrest 20 and the footrest 10.
[0043] In some examples, the sliding fitting 31 is connected to the foot rest 10, and the sliding member 32 is connected to the leg rest 20. Thus, when the sliding member 32 slides along the sliding fitting 31, the leg rest 20 slides accordingly as the sliding member 32 slides, and the foot rest 10 remains stationary as the sliding fitting 31 remains stationary, thereby changing the distance between the leg rest 20 and the foot rest 10, and further adjusting the distance between the leg rest 20 and the foot rest 10.
[0044] Of course, it is understood that, as a modified embodiment, the connection of the adjustment assembly 30 may also be such that the sliding member is connected to the leg rest, and the sliding member is connected to the foot rest. Thus, when the sliding member slides along the sliding member, the foot rest will slide accordingly with the sliding member, and the leg rest will remain stationary accordingly with the sliding member remaining stationary, thereby changing the distance between the foot rest and the leg rest, and further adjusting the distance between the leg rest and the foot rest.
[0045] Optionally, see Figure 1 and Figure 2, one of the sliding member 32 and the sliding fitting member 31 is connected to the back of the leg rest 20. For example, when the sliding member 32 is connected to the leg rest 20, the sliding member 32 is arranged on the back 21 of the leg rest 20. Alternatively, when the sliding fitting member is connected to the leg rest, the sliding fitting member is connected to the back of the leg rest. Thus, when the support assembly moves to pull the patient's legs and feet to move, the sliding fitting member 31 or the sliding member 32 will be carried under the leg rest 20, thereby supporting the leg rest 20, and then the leg rest 20 can be stably supported under working conditions, and the leg rest 20 is difficult to flip over and deform, thereby making the leg rest 20 stable when working.
[0046] Figure 4 is a cross-sectional view of an adjustment assembly according to an embodiment of the present disclosure. Figure 3 and Figure 4 The sliding member 32 is further provided with a locking member 322 that can slide toward / away from the locking portion 312.
[0047] Optionally, a second slot 3203 is formed on the sliding member 32, and the second slot 3203 extends perpendicularly to the first slot 3101. The locking member 322 is slidably disposed within the second slot 3203. Thus, when the locking member 322 slides along the second slot 3203, it moves along the width of the first slot 3101, thereby moving toward or away from the locking portion 312 on the inner wall of the first slot 3101.
[0048] When the locking member 322 is coupled to the locking portion 312 , the relative sliding between the sliding fitting member 31 and the sliding member 32 is locked. When the locking member 322 is disengaged from the locking portion 312 , the relative sliding is unlocked.
[0049] In other words, when the locking member 322 slides toward the locking portion 312 and engages with the locking portion 312, the engagement between the locking member 322 and the locking portion 312 prevents the sliding member 32 from sliding along the sliding fitting member 31, and the sliding member 32 remains fixed relative to the sliding fitting member 31. When the locking member 322 slides away from the locking portion 312 and disengages from the locking portion 312, the disengagement between the locking member 322 and the locking portion 312 releases the locked state between the sliding member 32 and the sliding fitting member 31, and the sliding member 32 can now slide along the sliding fitting member 31.
[0050] Optionally, the locking portion 312 is configured to be able to fit concavely and convexly with the locking member 322. That is, one of the inner side wall of the first chute 3101 and the locking member 322 is formed with a concave portion, and the other is formed with a convex portion that can fit with the concave portion. Specifically, for example, the locking portion 312 is formed as a convex portion provided on the inner side wall of the first chute 3101. The locking member 322 is formed with a concave portion that fits with the convex portion. Alternatively, the locking portion is formed as a concave portion provided on the inner side wall of the first chute, and the locking member is formed with a convex portion that fits with the concave portion. Thus, when the locking portion 312 and the locking member 322 fit concavely and convexly, the friction force between the locking portion 312 and the locking member 322 is large, and this friction force can prevent the locking member 322 and the sliding member 32 connected to the locking member 322 from sliding, thereby having a good locking effect on the sliding member 32.
[0051] Optionally, the extending direction of the locking portion 312 is consistent with the sliding direction of the sliding member 32. Thus, when the sliding member 32 slides to any position along the sliding fitting member 31, the locking member 322 provided on the sliding member 32 can be locked and matched with the locking portion 312, thereby achieving the effect of steplessly locking the relative sliding between the sliding member 32 and the sliding fitting member 31.
[0052] The operating member 33 is connected to the locking member 322 and is operable to drive the locking member 322 to slide. That is, the user can operate the operating member 33 to drive the locking member 322 to slide toward the locking portion 312, thereby engaging the locking member 322 with the locking portion 312. The user can also operate the operating member 33 to drive the locking member 322 to slide away from the locking portion 312, thereby disengaging the locking member 322 from the locking portion 312. Thus, when the user adjusts the distance between the leg rest 20 and the foot rest 10, the user operates the operating member 33 by applying a small operating force, causing the operating member 33 to drive the locking member 322 to move for locking and unlocking, and by having the sliding member 32 slide on the sliding fitting member 31, the distance between the foot rest 10 and the leg rest 20 is adjusted. The above operation requires little effort and is easy to operate, thereby making the distance between the leg rest 20 and the foot rest 10 easy to adjust and the adjustment efficiency high.
[0053] Optionally, see Figure 3 and Figure 4When the footrest 10 and the legrest 20 are respectively the left footrest and the left legrest, the operating portion 332 of the operating member 33 is located on the left side of the sliding member 31 and the sliding member 32. When the footrest 10 and the legrest 20 are respectively the right footrest and the right legrest, the operating portion 332 of the operating member 33 is located on the right side of the sliding member 31 and the sliding member 32.
[0054] It can be understood that when the patient uses the support assembly for rehabilitation training, the left leg and left foot of the patient's left lower limb will be supported by the left leg support and the left foot support respectively, and the right leg and right foot of the patient's right lower limb will be supported by the right leg support and the right foot support respectively. At this time, the left side of the patient's left lower limb and the right side of the patient's right lower limb have a larger blank space for operation.
[0055] Therefore, when the footrest 10 and the legrest 20 are the left footrest and the left legrest, respectively, the operating portion 332 is arranged on the left side of the sliding member 32 and the sliding fitting member 31, so that it is convenient for the user to operate on the left side of the left footrest and the left legrest, and when the user adjusts the distance between the left legrest and the left footrest, the user has a large operating space, which is convenient for operation. Similarly, when the footrest 10 and the legrest 20 are the right footrest and the right legrest, respectively, the operating portion 332 is arranged on the right side of the sliding member 32 and the sliding fitting member 31, so that it is convenient for the user to operate on the right side of the right footrest and the right legrest, and when the user adjusts the distance between the right legrest and the right footrest, the user has a large operating space, which is convenient for operation.
[0056] Optionally, the operating member 33 further includes a threaded portion 331. The threaded portion 331 is connected to the locking member 322. The operating portion 332 is connected to the threaded portion 331. Specifically, the operating portion 332 can be configured as a knob or a rotary handle. Thus, when a user rotates the knob or the rotary handle, the knob or the rotary handle can drive the threaded portion 331 to rotate, thereby driving the locking member 322, which is trapped in the second sliding groove 3203, to slide.
[0057] Optionally, see Figure 2 and Figure 4The adjustment assembly 30 further includes an outer covering member 34. The outer covering member 34 forms an outer covering hole 3401 for covering the outer periphery of the sliding member 31 and the sliding member 32. The inner portion of the outer covering member 34 is connected to the sliding member 32, and the outer portion of the outer covering member 34 is connected to the leg support 20 or the foot support 10, so as to slide with the sliding member 32 and drive the leg support 20 or the foot support 10. As a result, the overall support assembly is aesthetically pleasing, and the outer covering member 34 can provide a certain degree of protection for the sliding member 31 and the sliding member 32, ensuring that the sliding member 31 and the sliding member 32 have a long service life.
[0058] The present disclosure also provides a rehabilitation training device, comprising a device body and the support assembly for rehabilitation training as described above, wherein the support assembly is movably connected to the device body.
[0059] Thus, when the user's feet and legs are supported by the support assembly, the user's feet and legs can move in response to the movement of the support assembly, thereby achieving the effect of rehabilitation training for the user's legs and feet. Of course, when the user's body has recovered to a certain level, the user can also actively drive the support assembly through their legs and feet to actively perform rehabilitation training.
[0060] Optionally, the support assembly can be rotatably mounted on the device body. For example, the support assembly can be rotatably connected to the crank 900 of the device body. Thus, the user can perform rotational motion via the support assembly, causing the user's lower limbs to perform circular motion as the support assembly rotates, achieving circular training for the user's lower limbs and facilitating lower limb rehabilitation.
[0061] The above embodiments are merely illustrative of the principles and effects of this disclosure and are not intended to limit this disclosure. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of this disclosure. Therefore, any equivalent modifications or alterations made by a person skilled in the art without departing from the spirit and technical concepts disclosed herein shall be encompassed by the scope of protection of this disclosure.
