Description

Technical Field

[0001] The utility model relates to the field of walking assistance devices, in particular to a one-key folding walking aid. Background Art

[0002] For people with mobility difficulties, walking aids are used to assist walking; walking aids are also known as walkers or walking assistance devices; they are usually used to help people with mobility difficulties (such as the elderly, disabled, or rehabilitation patients) walk more steadily and safely; walking aids can provide additional support and stability to reduce the risk of falling; when the elderly use a walking aid, they need to hold the handrails of the walking aid tightly to maintain support for themselves, otherwise the elderly are likely to break away from the walking aid and fall.

[0003] In view of the above related technologies, when people with walking difficulties pick up food, because they need to hold the walking aid tightly to assist walking, it is difficult to hold the food tray tightly, which is not convenient for such people to pick up food. Content of the Utility Model

[0004] In order to facilitate people with walking difficulties to pick up food, the present application provides a one-key folding walking aid.

[0005] The one-key folding walking aid provided by the present application adopts the following technical solutions:

[0006] The one-key folding walking aid includes a frame and a tray assembly. An armrest is provided at the top of the frame, and the tray assembly is installed on the frame and is located directly below the armrest; a storage member is slidably installed on the frame; a plurality of pairs of rollers are rotatably installed at the bottom of the frame.

[0007] By adopting the above technical solutions, when people with mobility difficulties such as the elderly use this walking aid, they first hold the armrests tightly and then walk by themselves, synchronously pushing the walking aid to move until they reach the food pickup area; after reaching the destination, they place the food on the tray assembly and then push the walking aid back; when using this walking aid, when the elderly hold the armrests tightly to hold the walking aid, the restaurant staff only need to place the food on the tray assembly to complete the food pickup, reducing the risk of falling due to lack of support after the elderly break away from the walking aid; at the same time, extra items can be placed in the storage member, further facilitating the travel of the elderly.

[0008] Preferably, the frame includes a pair of relatively arranged single frames. Each single frame includes a first support rod and a second support rod that are cross-arranged. The first support rod and the second support rod are rotatably connected at the intersection. The tray assembly is installed between the two single frames. The first support rod is rotatably connected to the tray assembly, and the second support rod is movably connected to the tray assembly.

[0009] By adopting the above technical solution, the first rod and the second rod are rotated relative to each other, so as to fold the walking aid, reduce the volume of the walking aid, and reduce the waste of indoor space resources.

[0010] Preferably, the tray assembly includes a tray body and a connecting frame. The tray body is mounted on the connecting frame. The first rod is rotatably mounted on the connecting frame. A first rotating rod is rotatably mounted on the second rod. The first rotating rod is rotatably mounted on the connecting frame. A sliding cavity is formed in the connecting frame. One end of the first rotating rod away from the second rod is slidably mounted on the connecting frame through the sliding cavity. A driving assembly for driving the first rotating rod to slide on the connecting frame is mounted on the connecting frame.

[0011] By adopting the above technical solution, after the driving assembly is started, the first rotating rod is driven to slide on the connecting frame. Under the limiting action of the sliding cavity, the end of the second rod is driven to slide on the connecting frame, so that the second rod rotates relative to the first rod, thereby folding the vehicle frame. The use of the connecting frame and the driving assembly can stably drive each second rod to rotate relative to the first rod, reducing the workload of the user in rotating the second rod.

[0012] Preferably, the driving assembly includes a driving rod, a linkage rod and a second rotating rod. The driving rod is mounted on the connecting frame. The second rotating rod is rotatably mounted on the connecting frame and the connection point is located at the midpoint of the second rotating rod. One end of the linkage rod is connected to one end of the driving rod and the other end is connected to the second rotating rod. A rotating head is rotatably connected to the end of the second rotating rod away from the linkage rod. One end of the rotating head away from the second rotating rod is rotatably connected to the first rotating rod. The rotating head is slidably mounted on the connecting frame through the sliding cavity.

[0013] By adopting the above technical solution, pulling the driving rod drives the connecting frame to move relative to the rotating head and tilt upward. At this time, the rotating head slides along the length direction of the sliding cavity, driving the second rod to rotate. This design only requires the user to pull the driving rod to drive the second rod to rotate relative to the first rod, reducing the workload of the elderly in folding the vehicle frame when using the walking aid and further facilitating the use of the walking aid by the elderly.

[0014] Preferably, a track is provided on the connecting frame, and a pulley is mounted on the receiving member. The pulley is rollably mounted on the track.

[0015] By adopting the above technical solution, the pulley changes the sliding friction into rolling friction, reducing the wear between the storage member and the connecting frame. While saving manpower, it reduces the loss of the walking aid and thus increases the service life of the walking aid. At the same time, compared with the general indoor walking aid that requires taking out the tray body before taking out the items in the lower storage member, the walking aid of the present application can take out the items in the storage member by pulling the storage member without taking out the tray body.

[0016] Preferably, a plurality of inner braces are arranged between the two single frames.

[0017] By adopting the above technical solution, the inner braces are used to connect the single frames on both sides. While improving the structural stability between the single frames, it enables the single frames on both sides to move synchronously, improving the stability of the synchronous movement of the first strut and the second strut on the single frames on both sides.

[0018] Preferably, both ends of the armrest are telescopically installed on the first struts of the two single frames.

[0019] By adopting the above technical solution, the adjustable armrest height facilitates the use of the walking aid by the elderly of different heights, improving the practicability of the walking aid.

[0020] Preferably, the tray assembly further includes a tray frame, the tray frame is installed on the connecting frame, and the tray body is detachably installed on the tray frame.

[0021] By adopting the above technical solution, after the meal is taken, the tray body can be directly removed to take out the food from the walking aid. The elderly do not need to take out the food from the walking aid one by one, reducing the risk of dropping when taking the food.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. When using this walking aid, in the state where the elderly hold the armrests tightly and thus hold the walking aid firmly, the restaurant staff only need to place the food on the tray assembly to complete the meal taking, reducing the risk of the elderly falling due to lack of support after leaving the walking aid. At the same time, the extra items can be placed in the storage member, further facilitating the walking of the elderly.

[0024] 2. Rotate the first strut and the second strut relative to each other to fold the walking aid, reducing the volume of the walking aid and reducing the waste of indoor space resources.

[0025] 3. The user only needs to pull the drive rod to drive the second strut to rotate relative to the first strut, reducing the workload of the elderly in retracting the frame when using the walking aid and further facilitating the use of the walking aid by the elderly.
