Description

Technical Field

[0001] This utility model relates to the field of foot pedal technology, specifically a detachable foot pedal for a wheelchair. Background Technology

[0002] A wheelchair is a device that helps people with mobility impairments to move independently or with assistance. It mainly consists of a seat, wheels, armrests, and footrests. Its core function is to replace or assist the lower limbs in moving, and it is suitable for people who have difficulty walking due to illness, injury, aging, or other reasons. In the design of a wheelchair, the footrests play a crucial role as an important component supporting the user's feet.

[0003] Currently used foot pedals can only support the user's feet. When encountering a user who has lost mobility, their feet are prone to falling off the foot pedal, affecting the movement of the wheelchair. In addition, the foot pedal is usually used at an upward lifting angle, which is relatively fixed and cannot be adjusted according to needs. Therefore, it is necessary to design a detachable foot pedal for wheelchairs to improve the existing shortcomings. Utility Model Content

Detailed Implementation

[0015] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0016] In the following description, embodiments of the detachable footrest of the wheelchair according to the present invention will be described with reference to the accompanying drawings.

[0017] Figures 1-4 This invention illustrates a detachable footrest for a wheelchair according to an embodiment of the present invention, comprising: The crossbars 3 are installed on the left and right ends of the front side of the wheelchair body 1. Specifically, the crossbars 3 are telescopic bars. The crossbars 3 are detachably installed on the front side of the wheelchair body 1 via the mounting clamp assembly 2. Specifically, the mounting clamp assembly 2 includes a fixed clamp 21 fixedly installed on the surface of the crossbar 3. A movable clamp 22 is rotatably connected to the rear side of the fixed clamp 21. Due to the deformable force of the movable clamp 22, different wheelchair bodies 1 can be installed through the mounting clamp assembly 2. An anti-detachment threaded rod 23 is inserted into the inner cavity of the movable clamp 22. The end of the anti-detachment threaded rod 23 near the fixed clamp 21 is threaded to the fixed clamp 22. The inner cavity of hoop 21 has a vertical rod 4 installed at the bottom of the horizontal bar 3. Specifically, the vertical rod 4 is a telescopic rod. Through the telescopic design of the horizontal bar 3 and the vertical rod 4, the working distance and height of the anti-slip double-sided pedal assembly 7 can be flexibly adjusted according to the user's actual situation to meet different usage needs. The bottom of the vertical rod 4 is rotatably connected to an adjusting rod 5 via a rotating locking mechanism. Specifically, the rotating locking mechanism includes a fixed post 9 fixedly installed at the bottom of the vertical rod 4. The adjusting rod 5 is sleeved on the surface of the fixed post 9, and a rotating compression cap 10 is threaded onto the surface of the fixed post 9. The adjusting rod 5 is adjusted by rotating the compression cap 10. The adjusting rod 5 is locked to the bottom of the vertical rod 4 by compression. A mounting block 6 is rotatably connected to the surface of the adjusting rod 5. An anti-slip double-sided pedal assembly 7 is mounted on the opposite side of the mounting block 6. Specifically, the anti-slip double-sided pedal assembly 7 includes a pedal 71 rotatably connected to the surface of the mounting block 6 via a rotating shaft 61. An anti-slip strip 72 is provided on the top of the pedal 71, and an anti-slip sleeve 73 is fixedly mounted on the bottom of the pedal 71. The anti-slip sleeve 73 is made of plastic and is detachably mounted on the surface of the pedal 71 by screws. The anti-slip double-sided pedal assembly 7 is locked to the surface of the mounting block 6 by a limiting component. Specifically, the limiting component… The positioning component includes a sliding insert 81 in the inner cavity of the mounting block 6. The opposite side of the insert 81 extends into the inner cavity of the pedal 71. The upper and lower ends of the pedal 71 near the mounting block 6 are provided with slots 86 that cooperate with the insert 81. An anti-detachment piece 84 is fixedly installed on the surface of the insert 81. The inner cavity of the mounting block 6 is provided with a movable cavity for the anti-detachment piece 84 to move. A spring 85 is provided in the inner cavity of the movable cavity. The spring 85 is sleeved on the surface of the insert 81. The opposite side of the insert 81 extends to the outer side of the inner cavity of the mounting block 6 and is fixedly installed with a limiting rod 82. A pull ring 83 is rotatably connected to the surface of the limiting rod 82. The mounting block 6 rotates at a 90-degree angle on the surface of the adjusting rod 5. When the anti-slip double-sided pedal assembly 7 is not in use, it can be rotated and folded up and down. The connection between the adjusting rod 5 and the mounting block 6 is prior art and will not be elaborated in detail in this application.

[0018] Working Principle: In use, the user places the movable hoop 22 onto the rod on the front side of the wheelchair body 1, then inserts the anti-detachment threaded rod 23 and rotates it, causing one end of the anti-detachment threaded rod 23 to be threaded into the inner cavity of the fixed hoop 21. This allows the movable hoop 22 to rotate on the surface of the fixed hoop 21, clamping the rod body between the fixed hoop 21 and the movable hoop 22, thus locking the crossbar 3 to the front side of the wheelchair body 1. The user then adjusts the length of the crossbar 3 and the vertical rod 4 according to actual needs, and rotates the adjusting rod 5 to adjust the angle of the anti-detachment double-sided pedal assembly 7. Once the angle is determined, the user rotates the rotating compression cap 10 to compress the adjusting rod 5. The adjusting rod 5 is locked at the bottom of the vertical rod 4 to determine the usage angle of the anti-slip double-sided pedal assembly 7. During normal use, the anti-slip strip 72 faces upward. When it is necessary to lock and limit the foot, pull the pull ring 83 to drive the limiting rod 82 and the insertion rod 81 to slide. At this time, the anti-slip piece 84 will slide in the movable cavity and compress the spring 85, causing the insertion rod 81 to disengage from the inner cavity of the slot 86 in the pedal 71. Then, flip the pedal 71 so that the anti-slip sleeve 73 faces upward, and then release the pull ring 83 to allow the insertion rod 81 to insert into the inner cavity of the other slot 86 to lock the pedal 71. The anti-slip sleeve 73 is used to limit the user's foot to the top of the pedal 71, thereby effectively preventing the user's foot from slipping off.

[0019] In summary, the detachable footrest of this wheelchair, connected by the adjustable rod 5, allows for adjustment of the angle of the anti-slip double-sided footrest assembly 7 as needed. Combined with the anti-slip double-sided footrest assembly 7, it achieves both normal lifting and limiting functions, thus improving the practicality of the footrest structure.

[0020] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
