Description

Technical Field

[0001] This utility model relates to the field of rehabilitation training walking aids, specifically an adjustable rehabilitation training walking aid. Background Technology

[0002] In the context of an aging society, the elderly population faces numerous health challenges, among which the risk of falls and the need for rehabilitation are particularly prominent. Falls, as one of the most common accidental injuries among the elderly, not only cause physical injuries such as fractures and soft tissue contusions, but can also trigger a series of serious complications, such as lung infections and deep vein thrombosis caused by prolonged bed rest, severely impacting the quality of life and self-care ability of the elderly. At the same time, many elderly people require rehabilitation exercises after chronic diseases, surgery, or accidental injuries to restore physical function, improve their ability to live independently, and prevent recurrence of falls.

[0003] For example, the Chinese authorized patent with publication number CN 222018617 U (An Adjustable Walking Aid) includes a support frame, a connecting strip, and an adjustment device. The connecting strip is fixed between two support frames. The adjustment device is disposed on the surface of the support frame and includes positioning holes on both sides of the connecting strip. Sliding strips are slidably connected to the surfaces of the positioning holes on both sides of the connecting strip. Positioning blocks are slidably connected to the inner surfaces of the sliding strips on both sides of the connecting strip. This invention effectively adjusts the walking aid by setting an adjustment device. When using the walking aid, the device is used to adjust the sliding strips and release the positioning blocks, preventing users from experiencing back pain due to height differences. This improves the practicality, assistive function, adjustability, and user comfort when using the walking aid.

[0004] While the existing technologies mentioned above have height adjustment capabilities, there are differences in body shape and weight among different elderly people. Existing walking aids are only adapted to height adjustment. When the body is too fat or too thin, the appropriate support position of the arm is often different. They lack personalized adjustment functions and are difficult to adapt to the specific needs of patients. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1-4 This utility model provides an embodiment of an adjustable rehabilitation training walking aid, comprising a walking aid body 1 composed of two symmetrically arranged support components 2. The walking aid body 1 serves as the support frame for the entire walking aid, ensuring structural stability. The support components 2 include several key parts that collectively enable height adjustment and assistive position adjustment of the walking aid.

[0025] Specifically, each support component 2 includes a first longitudinal connecting rod 4, with a first gripping glove on its exterior for easy gripping by the patient. The front end of the first longitudinal connecting rod 4 is connected to a first support rod 3 via a bent tube, and the rear end of the first longitudinal connecting rod 4 is connected to an oblique connecting rod 5 via a bent tube, with the oblique connecting rod 5 tilted forward. The other end of the oblique connecting rod 5 is connected to a second longitudinal connecting rod 6, with a third gripping glove on its exterior. When the patient needs to stand up while seated, they can grasp the third gripping glove and apply force to facilitate standing. The rear end of the second longitudinal connecting rod 6 is connected to a second support rod 7 via a bent tube. The first support rod 3, first longitudinal connecting rod 4, oblique connecting rod 5, second longitudinal connecting rod 6, and second support rod 7 are integrally formed, ensuring the structural stability of the entire support component 2. The lower ends of the first support rod 3 and second support rod 7 are telescopically connected to adjustable support legs 8 for adjusting the height of the walker. A connecting half-frame 9 is fixed between the first support rod 3 and second support rod 7 on each support component 2 via fixing pins to increase the overall stability of the walker.

[0026] This part is not much different from the existing walking aids. As the basic frame structure, it provides stable assistance. The height adjustment of the lower adjustable support leg 8, the first support rod 3, and the second support rod 7 is consistent with the existing structure. Press the adjusting protrusion on the first support rod 3 or the second support rod 7, and at the same time pull the adjustable support leg 8 outward to adjust the height of the entire walking aid.

[0027] like Figures 1-4 As shown, a rotating sleeve 10 is provided on the upper outer end of the first support rod 3. A connecting vertical plate 11 is fixed between the upper ends of the two rotating sleeves 10. A slot is opened on the end face of the rotating sleeve 10, and a fixing protrusion 12 is fixed on the outside of the first support rod 3 along the slot position of the rotating sleeve 10. The rotating sleeve 10 is rotatably connected to the first support rod 3 by the limiting sliding of the fixing protrusion 12 in the slot. The lower ends of the first longitudinal connecting rods 4 on the two support assemblies 2 are also rotatably connected to connecting pipes 14, and an upper connecting crossbar 13 is connected between the two connecting pipes 14, further increasing the overall stability of the walker.

[0028] This part of the structure is not much different from the existing automatic adjustment structure. The main difference is that the entire assist device can be pulled and deformed to match the turning position requirements during rehabilitation exercises.

[0029] like Figures 1-4 and Figure 6 As shown, a transverse rod 16 is slidably connected to the first longitudinal connecting rod 4. A longitudinal rod 17 is integrally connected to both sides between each group of two transverse rods 16. A second armrest is provided on the outside of the longitudinal rod 17. The transverse rods 16 and the longitudinal rods 17 together constitute the power assist adjustment component 15, which is used to adjust the position of the second armrest.

[0030] To enable flexible adjustment of the power assist adjustment component 15, the upper and lower ends of the outer surface of the transverse rod 16 are provided with first slots 19, and limit protrusions 22 are slidably connected within the first slots 19. The upper and lower ends of the outer surface of the first longitudinal connecting rod 4 are provided with slots 18, and the limit protrusions 22 corresponding to the slots 18 extend outward through the slots 18. When it is necessary to adjust the position of the power assist adjustment component 15, simply press the two upper limit protrusions 22. Since the inner end of the limit protrusion 22 is fixed with a limit plate 21, and the limit plate 21 slides along the second slot 20, and a pressure spring 23 is provided between the limit plate 21 and the end face of the second slot 20 along the outside of the limit protrusion 22, pressing the limit protrusion 22 will cause the upper limit protrusion 22, the limit plate 21, and the rack 24 to move downward. Meanwhile, since the middle of the second slot 20 is rotatably connected to the intermediate gear 25 via a shaft, and two racks 24 are symmetrically arranged in each second slot 20 and mesh with the intermediate gear 25, the downward movement of the upper rack 24 will drive the lower rack 24 to move upward, thereby causing the lower limiting protrusion 22, the limiting disc 21, and the rack 24 to move upward. When the limiting protrusion 22, which is locked outside the slot 18, disengages from the slot 18, the assist adjustment component 15 can be pulled to adjust its position until the position of the second armrest matches the patient's support position. Under the action of the pressure spring 23, the structure rebounds, causing the limiting protrusion 22 to re-lock into the slot 18, fixing the position of the assist adjustment component 15. This design makes the adjustment process of the assist adjustment component 15 simple and quick, and the position after adjustment is stable and reliable, which can meet the needs of different patients.

[0031] like Figure 5As shown, a detachable component 27 is provided at the lower outer end of the rotating sleeve 10. The detachable component 27 consists of a fixed block, a half-ring fixed to the fixed block, a movable half-ring, and bolts. The half-ring fixed to the fixed block and the movable half-ring are placed outside the rotating sleeve 10 and locked with bolts to achieve the installation and fixation of the basic structure. An outer rotating tube 28 is fixed to the rear end of the detachable component 27, and a first lower support rod 29 is rotatably connected between the two outer rotating tubes 28. A seat cushion 30 is welded to the front end of the first lower support rod 29 for the patient to sit and rest when tired. A second lower support rod 31 is welded to the upper rear end of the seat cushion 30, and outer fixing tubes 32 are fixed to both ends of the second lower support rod 31. A first C-shaped buckle 33 is fixed to the rear end of the outer fixing tube 32. The inner diameter of the first C-shaped buckle 33 matches the longitudinal diameter of the connecting half-frame 9, and is used to fix the position of the seat cushion 30 after it is folded. The front end of the outer fixing tube 32 is fixed with a second C-shaped buckle 34. The inner diameter of the second C-shaped buckle 34 matches the outer diameter of the rotating sleeve 10, and is used to fix the position of the seat cushion 30 when it is not in use. The detachable part 27, the outer rotating tube 28, the first lower support rod 29, the seat cushion 30, the second lower support rod 31, the outer fixing tube 32, the first C-shaped buckle 33 and the second C-shaped buckle 34 together constitute the detachable component 26, which realizes the flexible folding and fixing of the seat cushion 30.

[0032] During exercise, if the patient feels tired, they can fold down the seat cushion 30, disengaging the second C-shaped buckle 34 from the rotating sleeve 10, placing the seat cushion 30 horizontally, and securing it to the outside of the longitudinal section connecting the half-frame 9 using the first C-shaped buckle 33. The patient can then sit on the seat cushion 30 to rest. After resting, the patient simply folds the seat cushion 30 upwards, re-engaging the second C-shaped buckle 34 onto the rotating sleeve 10 to resume exercise. This design allows patients to rest at any time during exercise, improving the continuity of rehabilitation training and the patient's rehabilitation experience.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
