Description

Technical Field

[0001] This utility model relates to the field of walking aid technology, specifically to a walking aid with a quick-release backrest. Background Technology

[0002] Walking aids are assistive walking tools designed specifically for the elderly. They are mainly used by seniors who have difficulty moving, are recovering from illness or surgery, or are physically weak. The aim is to help them perform daily activities more easily and safely, while reducing the risk of falls and other accidents. When seniors need to move from bed to a walking aid, they usually have to stand up first and then slowly sit on the walking aid. Even with assistance, this process can be difficult and carries the risk of falling. Currently, most walking aids do not integrate well with the bed to facilitate easy movement for seniors, resulting in certain safety risks when using walking aids.

[0003] Based on the above, Chinese Patent No. CN221654860U discloses a foldable walking aid, including two seats and a frame tube. A pad is fixedly installed on the top of each seat, and two brackets are fixedly installed on the bottom of each seat. A second bracket is fixedly installed on the inner side of the frame tube. Front limiting hinge seats are fixedly installed at both ends of the frame tube. Handrails are hinged to the outer sides of the front limiting hinge seats. Connecting support rods are fixedly installed at the bottom of each handrail. A front wheel is fixedly installed at the end of the connecting support rod away from the handrail. A connecting frame rod is fixedly installed on the outer side of the second bracket. A first bracket is fixedly installed at the end of the connecting frame rod away from the second bracket. Rear limiting hinge seats are hinged to both ends of the first bracket. A rear support rod is fixedly installed on the outer side of the rear limiting hinge seat. A rear wheel is fixedly installed at the end of the rear support rod away from the rear limiting hinge seat.

[0004] The aforementioned patent document discloses a walking aid that can be easily stored by folding. For elderly people with limited mobility, their reliance on walking aids is relatively high. The folding and storage function of the walking aid does not improve the convenience of use for the elderly. Furthermore, when the elderly need to get up and sit on the walking aid, they need to stand up from the bedside first, and then sit on the walking aid with their back to the walking aid or at an angle with their back to the walking aid. The elderly are at risk of falling during this process. Therefore, there is still room for improvement in this walking aid. Utility Model Content

[0026] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0027] like Figure 1 As shown, a walking aid with a quick-release backrest includes a walking aid body 1 and a quick-release backrest 2. The walking aid body 1 consists of a support frame 11 and a seat cushion 12. The seat cushion 12 is located inside the support frame 11. The quick-release backrest 2 is located above the rear edge of the seat cushion 12. Quick-release mechanisms 3 are provided between the left and right ends of the quick-release backrest 2 and the support frame 11. The quick-release mechanisms 3 are located above the left and right edges of the seat cushion 12. The quick-release mechanism 3 includes the following structure: a quick-release slot block 31, the rear end of which is fixedly connected to the quick-release backrest 2 and the front end of which is provided with a quick-release slot 32; a quick-release rod 33, the front end of which is fixedly connected to the support frame 11 and the rear end of which extends into the quick-release slot 32; a fixing groove 34 is provided at the position of the quick-release rod 33 inside the quick-release slot 32; and a fixing spring block 35 that matches the fixing groove 34 is provided on the quick-release slot block 31.

[0028] This utility model is mainly intended for use by elderly people who are immobile, recovering from illness or surgery, or are physically weak. The support frame 11 provides support for the walking aid body 1. When using the walking aid, the elderly can sit on the seat 12. The support frame 11 has several support feet 13 extending downward along the edge of the seat 12. The bottom of the support feet 13 is movably connected to the walking aid pulleys 14. A push handle 15 is provided on one side of the top of the support frame 11. Family members or others can push the walking aid through the push handle 15. The walking aid slides through the walking aid pulleys 14 at the bottom of the four support feet 13, giving the walking aid a function similar to a wheelchair. In addition, a brake grip can be provided at the push handle 15, and an active braking device similar to that in the patent document CN209422396U is adopted. A braking structure extending from the push handle 15 to the walking aid pulleys 14 is provided in the walking aid body 1. During the pushing of the walking aid, active braking can be achieved through the braking structure, improving the safety of the walking aid on uphill or downhill roads.

[0029] Furthermore, the walking aid body 1 can be equipped with a battery, motor, control system and other structures. Under the control of the control system, the battery provides power to the motor and drives the walking aid pulley 14 to rotate, so that the walking aid has the function of an electric wheelchair. It can move to the place it wants to go without the help of relatives or others, thus improving the convenience of the elderly with mobility difficulties in their daily lives.

[0030] After adopting the above structure, it should be further explained that, referring to Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 The quick-release rod 33 is inserted into the quick-release slot 32 and locked into the fixed slot 34 by the fixing spring block 35, thus fixing the quick-release backrest 2 to the walking aid body 1. When the elderly need to sit up from the bed onto the walking aid, they can press the fixing spring block 35 to disengage it from the fixed slot 34, allowing the quick-release backrest 2 to be pulled out from the quick-release rod 33 and removed. Then, the rear of the walking aid is placed close to the edge of the bed. The elderly can move their buttocks onto the seat cushion 12 from a lying position and then sit up from the walking aid body 1. By inserting the quick-release rod 33 into the quick-release slot 32 and the fixing spring block 35 into the fixing slot 34, the quick-release backrest 2 is fixed to the walking aid body 1. This allows the elderly to avoid having to stand up from the bedside before sitting on the walking aid, thus preventing accidents such as falls during the process. Similarly, when the elderly need to move from the walking aid to the bed, the quick-release backrest 2 can be removed through the quick-release mechanism 3, and then they can lie down directly on the bed from the walking aid body 1. This avoids accidents during the transfer between the bed and the walking aid and improves the safety of the transfer process.

[0031] In addition, when packaging the walking aid, the quick-release backrest 2 can be separated from other components of the walking aid body 1 and packaged independently, reducing the space occupied after packaging. The quick-release backrest 2 can avoid defects such as deformation and dents caused by squeezing during product transportation, thus avoiding consumer complaints and improving consumer satisfaction. Furthermore, the quick-release backrest 2 can be quickly fixed to the walking aid body 1 through the quick-release mechanism 3, reducing the difficulty of installing the walking aid.

[0032] As a first preferred embodiment of the quick-release backrest 2 and quick-release mechanism 3 of this utility model, refer to Figure 2 , Figure 3 , Figure 4The fixed slot 34 passes through the left and right sides of the quick-release rod 33.
