Description

Technical Field

[0001] This utility model relates to a wheelchair footrest fixing structure, belonging to the field of wheelchair technology. Background Technology

[0002] Currently, most wheelchairs on the market have two foot pedals installed on each of the two footrests. When the foot pedals are open, they are positioned under the feet. However, when the user needs to place their feet on the ground to rest and relax, they need to extend their feet in front of the foot pedals. If the user's legs are short, the foot pedals may cause the feet to dangle and press against the user's Achilles tendons, reducing the comfort of using the wheelchair.

[0003] Chinese patent application CN209107847U discloses an improved wheelchair foot pedal, which includes two foot pedals extending vertically from the wheelchair, and a pivot rod recessed towards the bottom of the wheelchair connected between the two foot pedals. The foot pedal is mounted on the pivot rod in a flip-up manner.

[0004] When the aforementioned wheelchair footrests are flipped, they rotate around the pivot rod. However, the footrests are prone to over-flipping, making it impossible to control the flipping angle. This causes the entire footrest to flip under the pivot rod, requiring the patient to stand up, bend over, and manually flip it back to its original position, or requiring assistance from others. This makes the footrests inconvenient to use. Utility Model Content

[0005] The purpose of this utility model is to provide a wheelchair footrest fixing structure that solves the problems of the inability to control the flip angle and inconvenience of use in the prior art.

[0006] The above-mentioned technical objective of this utility model is mainly achieved through the following technical solution: a wheelchair footrest fixing structure, including a footrest bracket and a footrest connected to the wheelchair seat and tilted towards the front of the wheelchair. The footrest bracket is provided with a crossbeam, and at least one fixing member is provided at the bottom of the crossbeam. The fixing member has a connecting part at its bottom. A T-shaped connecting block is provided at the rear edge of the footrest and is rotatably connected to the connecting part. The protruding end of the T-shaped connecting block has a limiting part that can contact the bottom surface of the connecting part. The footrest bracket supports the bottom of the footrest. The rear edge of the footrest is rotatably connected to the connecting part through the T-shaped connecting block, so that after the footrest is flipped, it is located behind the crossbeam, maintaining the flipping function. The setting of the limiting part allows the footrest to be flipped after it is flipped, and the contact between the limiting part and the bottom of the fixing member limits the flipping angle of the footrest, so that the footrest position is kept behind the crossbeam. Therefore, when the footrest needs to be returned to its original position, it can be easily pushed by the foot. It is simple, convenient and stable to use.

[0007] Preferably, the bottom of the crossbeam is provided with two connecting parts that are distributed and parallel to each other along the length of the crossbeam, and the rear edge of the foot pedal is provided with two T-shaped connecting blocks that correspond one-to-one with the connecting parts. The connecting parts are distributed along the length of the crossbeam and connected to the corresponding T-shaped connecting blocks, which can increase the connection area between the foot pedal and the connecting parts, making the foot pedal more stable and reliable when flipping, and strengthening the connection strength of the connection structure.

[0008] Preferably, the rear side of the connecting part extends toward the rear side of the wheelchair seat and toward the rear side of the crossbeam. The connecting part is connected to the protruding part of the T-shaped connecting block through a flange bearing. The rear side of the connecting part extends toward the rear side of the wheelchair seat and toward the rear side of the crossbeam, which increases the distance between the rotation center of the foot pedal and the contact point of the crossbeam, and extends the support arm of the foot pedal, thereby reducing the support burden on the foot pedal and reducing the space occupied by the foot pedal after it is flipped over, thus improving space utilization.

[0009] Preferably, the crossbeam is configured in a flat shape, and the flat surface of the crossbeam can contact the bottom surface of the foot pedal. The flat shape of the crossbeam increases the contact area between the crossbeam and the bottom surface of the foot pedal, thereby enhancing the stability of the foot pedal support and thus strengthening the foot pedal support strength.

[0010] Preferably, a pad is provided on the side of the foot pedal that contacts the flat surface of the crossbeam; the pad can increase the buffer layer, reduce the impact of the foot pedal on the crossbeam, and reduce the noise when the foot pedal flips.

[0011] Therefore, this utility model has the advantages of limiting the flipping angle of the foot pedal and being simpler and more convenient to use. Attached Figure Description

[0015] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0016] like Figure 1-3As shown, a wheelchair footrest fixing structure includes a footrest bracket 1 and a footrest 2 that are connected to the wheelchair seat and tilted towards the front of the wheelchair. The footrest bracket 1 is provided with a crossbeam 11, and at least one fixing member 12 is provided at the bottom of the crossbeam 11. The fixing member 12 is provided with a connecting part 121 at the bottom. A T-shaped connecting block 21 that is rotatably connected to the connecting part 121 is provided at the rear edge of the footrest 2. The protruding end of the T-shaped connecting block 21 is provided with a limiting part 211 that can contact the bottom surface of the connecting part 121. A gasket 22 is provided on the side of the footrest 2 that contacts the flat surface of the crossbeam 11.

[0017] The aforementioned footrest bracket is connected to the wheelchair seat and extends and tilts towards the front of the wheelchair. A crossbeam is provided at the bottom of the footrest bracket to fix and support the foot pedal. The foot pedal is located behind the crossbeam. A T-shaped connecting block is fixed to the rear edge of the bottom of the foot pedal by bolts. The connecting part is fixed to the bottom of the crossbeam by bolts. The T-shaped connecting block is rotatably connected to the connecting part through a flange bearing, so that the foot pedal can rotate behind the crossbeam and realize the flipping of the foot pedal. When the foot pedal flips, the front side of the limiting part at the end of the protruding part of the T-shaped connecting block abuts against the bottom surface of the fixing part, so that the maximum angle of the foot pedal flipping is blocked by the fixing part. That is, after the foot pedal flips, it is limited and supported by the bottom surface of the fixing part. The aforementioned gasket is made of rubber or silicone material and is glued to the bottom of the foot pedal.

[0018] like Figure 2 As shown, the bottom of the crossbeam 11 is provided with two connecting parts 121 that are distributed and arranged in parallel along the length direction of the crossbeam 11. The rear edge of the foot pedal 2 is provided with two T-shaped connecting blocks 21 that correspond one-to-one with the connecting parts 121. The rear side of the connecting parts 121 extends toward the wheelchair seat to the rear side of the crossbeam 11. The connecting parts 121 are connected to the protruding parts of the T-shaped connecting blocks 21 through flange bearings. The crossbeam 11 is provided with a flat structure, and the flat surface of the crossbeam 11 can contact the bottom surface of the foot pedal 2.

[0019] The two fixing components are distributed in parallel, and the T-shaped connecting blocks are distributed in parallel at the bottom of the foot pedal. The connecting part of the bottom of a single fixing component extends towards the rear side of the crossbeam and is rotatably connected to a single T-shaped connecting block. The connecting part extends to the position below the rear side of the crossbeam. When the foot pedal is flipped to a vertical position, it is spaced a certain distance from the rear side of the crossbeam. The limiting part at the end of the protruding part of the connecting part abuts against the bottom surface of the fixing component, limiting the maximum flipping angle of the foot pedal and making the foot pedal vertical. This reduces space occupation and effectively and rationally utilizes the wheelchair space. When needed, the user can push the upper side of the foot pedal with both feet to push and flip the foot pedal to contact the top surface of the crossbeam. At this time, the pad on the bottom surface of the foot pedal contacts the flat surface of the crossbeam, realizing the support function for the user's feet.
