Abstract
Description
Technical Field
[0001] This utility model relates to the field of assistive rehabilitation equipment technology, specifically to a standing transfer aid with adjustable support width. Background Technology
[0002] Standing transfer aids are important assistive devices used to help the elderly, disabled, or post-operative rehabilitation populations transition between sitting and standing positions, as well as move short distances. They are widely used in homes, nursing homes, rehabilitation centers, and other settings.
[0003] Existing standing transfer aids mostly have a fixed support width or require manual adjustment using tools such as bolts and knobs. This results in cumbersome adjustment operations and an inability to quickly adapt to the user's body type and usage scenario, such as transferring from a wheelchair to a bed or from a chair to a bathroom. Some adjustable aids also suffer from poor synchronization of the support structures on both sides during adjustment, requiring users to bend over, which creates obstacles for those with mobility impairments. Furthermore, they lack anti-slip and braking safety structures, making them prone to tipping and sliding during use, which seriously affects the user experience and safety.
[0004] To address the aforementioned technical problems, this utility model proposes a standing transfer aid with adjustable support width. It achieves rapid and synchronous adjustment of the support width through a foot-operated adjustment structure, and is equipped with anti-slip and braking designs to improve the practicality and safety of the device. Utility Model Content
[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a standing transfer aid with adjustable support width, which has the characteristics of convenient adjustment, good synchronization and safety and reliability, and can quickly adapt to different user body types and usage scenarios.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a standing transfer aid with adjustable support width, comprising a bottom adjustable support structure, a handrail mechanism, and a support mechanism. The handrail mechanism and the support mechanism are both mounted on the bottom adjustable support structure, forming a stable overall support structure to ensure that the equipment does not shake or tip over during user transfer. The bottom adjustable support structure includes a width adjustment mechanism and a sliding mechanism. The width adjustment mechanism includes a pedal assembly, two telescopic adjustment rods connected to the two end faces of the pedal assembly, and a linkage transmission assembly. The pedal assembly includes a left adjustable pedal and a right adjustable pedal. The pedal assembly is hinged to the outer side of the bottom support. The structure allows for flexible rotation of the pedals, reducing foot resistance. The linkage transmission assembly is linked to the left and right adjustment pedals and the telescopic adjustment rods. Stepping on the left adjustment pedal drives the two telescopic adjustment rods to retract inwards synchronously, and stepping on the right adjustment pedal drives the two telescopic adjustment rods to expand outwards synchronously. Width adjustment can be completed simply by stepping on the pedals without the need for additional tools. This convenient and synchronized operation allows for quick adaptation to the width requirements of users of different body types and in different transfer scenarios. The sliding mechanism includes a caster frame assembly and casters. The caster frame assembly is connected to the telescopic adjustment rods, and the casters enable flexible movement of the equipment, reducing the burden on users during transfers and improving the equipment's mobility.
[0007] A further improvement of this utility model is that the telescopic adjusting rod has a sleeve structure, including an outer tube and an inner tube. The inner tube is slidably sleeved inside the outer tube. The connecting rod transmission assembly is hinged to the inner tube. The outer tube is fixedly connected to the outside of the bottom support. The sleeve structure not only ensures that the inner tube slides smoothly inside the outer tube, ensuring a smooth and uninterrupted width adjustment process, but also improves the structural strength and load-bearing capacity of the telescopic adjusting rod, avoiding deformation and breakage during adjustment, and extending the service life of the equipment.
[0008] A further improvement of this utility model is that the linkage transmission assembly includes two sets of linkage assemblies, each set of linkage assemblies including a left active linkage and a right active linkage. One end of the left active linkage is hinged to the caster frame assembly, which is connected to the width adjustment mechanism, and the other end is connected to the inner tube. The right active linkage is hinged to the adjusting pedal. The two sets of linkage assemblies are symmetrically arranged, which can evenly transmit the pedal force to the telescopic adjusting rod, ensuring that the two telescopic adjusting rods move synchronously, avoiding unilateral deviation, improving adjustment accuracy and equipment stability. At the same time, the linkage transmission structure has high transmission efficiency, reduces force loss, and reduces the user's pedaling force requirements.
[0009] A further improvement of this utility model is that the caster frame assembly includes two caster rods respectively connected to the left and right active connecting rods, and each caster rod is equipped with a caster. The two caster rods correspond to the support structures on both sides of the equipment, so that the equipment is evenly stressed and is not easy to tip over during movement. At the same time, the stable connection between the casters and the caster rods can improve the load-bearing capacity of the equipment and adapt to users of different weights.
[0010] A further improvement of this utility model is that the caster is mounted on the caster frame assembly, and the caster is equipped with a brake. The brake can quickly fix the caster after the equipment is adjusted to a suitable width or moved to the target position, preventing the equipment from sliding accidentally and avoiding the user from falling due to equipment displacement during standing or moving, thus significantly improving the safety of use, especially suitable for smooth ground scenarios.
[0011] A further improvement of this utility model is that: both the left and right adjusting pedals are provided with several raised anti-slip structures above them. These raised anti-slip structures increase the friction between the foot and the pedal, effectively preventing the user's foot from slipping when stepping on the pedal. Even when feet are wet or slippers are worn, the stability of stepping is guaranteed, reducing the risk of operational errors and improving the safety and reliability of use. The beneficial effects of this utility model are: 1. This utility model, by setting up a linkage structure of left and right adjustment pedals, linkage transmission components, and telescopic adjustment rods, allows users to drive the two telescopic adjustment rods to retract or expand synchronously without the need for tools, simply by stepping on the corresponding pedals. This enables rapid adjustment of the support width, making the operation convenient and the synchronization excellent. It can quickly adapt to users of different body types and different transfer scenarios, solving the problems of cumbersome adjustment and poor adaptability of existing equipment.
[0012] 2. The telescopic adjustment rod adopts a sleeve structure, with the inner and outer tubes sliding together to ensure a smooth and stable adjustment process while improving structural support strength; the raised anti-slip structure above the pedal and the brake design of the casters provide multiple safety protections to effectively prevent slipping, tipping or bumping during use, significantly improving the safety and comfort of the equipment and reducing the risk of use for people with mobility impairments.

Detailed Implementation
[0015] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0016] The purpose of this utility model is to address the technical problems existing in the prior art by providing an adjustable support width standing transfer aid, including a bottom adjustable support structure 1, a handrail mechanism 2, and a support mechanism 3. The handrail mechanism 2 and the support mechanism 3 are both mounted on the bottom adjustable support structure 1. The bottom adjustable support structure 1 provides support and a base for movement for the entire device. The handrail mechanism 2 is for the user to hold and maintain balance. The support mechanism 3 is used to assist in supporting the user's body and improve stability during the transfer process.
[0017] The bottom adjustable support structure 1 includes a width adjustment mechanism 4 and a sliding mechanism 5. The width adjustment mechanism 4 includes a pedal assembly 6, two telescopic adjustment rods 7, and a linkage transmission assembly 8. The pedal assembly 6 includes a left adjustable pedal 9 and a right adjustable pedal 10.

The linkage transmission assembly 8 is linked with the left adjustable pedal 9, the right adjustable pedal 10, and the telescopic adjustment rods 7 respectively. When the left adjustable pedal 9 is stepped on, the linkage transmission assembly 8 drives the two telescopic adjustment rods 7 to retract inward synchronously, reducing the support width of the equipment. When the right adjustable pedal 10 is stepped on, the linkage transmission assembly 8 drives the two telescopic adjustment rods 7 to expand outward synchronously, increasing the support width of the equipment. It can be quickly adjusted without tools to adapt to different usage needs.
[0018] The sliding mechanism 5 includes a caster frame assembly 16 and casters 17. The caster frame assembly 16 is connected to the telescopic adjustment rod 7, and the casters 17 facilitate the overall movement of the equipment and make it convenient for users to move short distances.
[0019] The telescopic adjustment rod 7 has a sleeve structure, including an outer tube 12 and an inner tube 13. The inner tube 13 is slidably sleeved inside the outer tube 12. The connecting rod transmission assembly 8 is hinged to the inner tube 13. The outer tube 12 is fixedly connected to the outside of the bottom support 4. The sleeve structure ensures that the inner tube 13 slides smoothly inside the outer tube 12, improving the smoothness of the adjustment process and the structural support strength.
[0020] The linkage transmission assembly 8 includes two sets of linkage assemblies. Each set of linkage assemblies includes a left active linkage 14 and a right active linkage 15. One end of the left active linkage 14 is hinged to the caster frame assembly 16, and the other end is connected to the inner tube 13. The right active linkage 15 is hinged to the adjusting pedal. Through the linkage of the left active linkage 14 and the right active linkage 15, the pedaling force is converted into the telescopic adjustment rod 7, thereby achieving synchronous adjustment.
[0021] The caster frame assembly 16 includes two caster rods 18 that are respectively connected to the left active link 14 and the right active link 15. Each caster rod 18 is equipped with a caster 17. The two caster rods 18 correspond to the support structures on both sides to ensure balance during movement.
[0022] The caster 17 is mounted on the caster frame assembly 16, and the caster 17 is equipped with a brake 19. When the equipment is adjusted to a suitable width or moved to the target position, the caster 17 is fixed by the brake 19 to prevent the equipment from sliding and improve the safety of use. Several raised anti-slip structures 11 are provided above the left adjustment pedal 9 and the right adjustment pedal 10 to increase the friction when stepping on them, prevent the user's feet from slipping, and further improve operational safety.
[0023] 1. Equipment positioning: Push the standing transfer aid to the target position and move it flexibly by rolling the casters 17 to adapt to different transfer scenarios.
[0024] 2. Width Adjustment: Users can choose to step on the left adjustment pedal 9 or the right adjustment pedal 10 according to their body size (weight) or the width requirements of the scene, without the need for additional tools.
[0025] 3. Linkage transmission: The pedal force is transmitted to the telescopic adjustment rod 7 through the linkage transmission assembly 8, the left active linkage 14 and the right active linkage 15. The left adjustment pedal 9 drives the two telescopic adjustment rods 7 to retract inward synchronously, and the right adjustment pedal 10 drives them to expand outward synchronously.
[0026] 4. Width adaptation: The inner tube 13 of the telescopic adjustment rod 7 slides smoothly within the outer tube 12, driving the caster frame assemblies 16 on both sides to move synchronously, thus achieving precise adaptation of the support width.
[0027] 5. Equipment Securing: After adjusting to the appropriate width, press the brake 19 on the caster 17 to lock the caster and prevent the equipment from sliding, ensuring stability during use.
[0028] 6. Transfer assistance: The user maintains balance by holding the non-slip handrail 20 and with the assistance of the support beam 21 and elastic protective pad 22, can switch between sitting and standing positions, or complete short-distance movement with the help of the fixed equipment.
[0029] 7. Adjustment and Reset: If you need to adjust the width again, release the brake piece 19 and repeat steps 2-4. The entire operation does not require bending over, making it suitable for people with mobility impairments.
