Description

Technical Field

[0001] The utility model relates to the field of seat cushions, in particular to a walking aid seat cushion. Background Art

[0002] A walking aid mainly helps patients stand and walk by means of upper limb strength, and can effectively help patients improve their walking ability. A large number of disabled patients need this kind of walking aid and rehabilitation auxiliary device. It has better stability and safety compared with axillary crutches and canes, and can play an exercise and rehabilitation effect compared with wheelchairs.

[0003] CN218685157U discloses a walking aid, which includes a flipable seat cushion. When folding, the seat cushion flips and clings to the support rod. When unfolding, the seat cushion flips and contacts the support rod, so that the seat cushion can be unfolded for people to sit. In this solution, the seat cushion is hinged to one of the support rods through a locking member, and the locking member is fixed to the back of the seat cushion by screws. When installing the seat cushion on the support rod, two workers are required to cooperate. One worker needs to align the position of the locking member with the seat cushion, and the other worker uses a screwdriver to fix the self-tapping screw to connect the locking member to the back of the seat cushion. The above method has the following defects: First, when installing the locking member, there will be a deviation in the accurate fixing position with the back of the seat cushion, which is likely to cause the seat cushion to rotate smoothly with the support rod; Second, after the locking member is installed, it cannot be disassembled because the screw hole on the plate surface is damaged after the self-tapping screw is driven once and cannot be used for the second time after disassembly. Users do not prepare self-tapping screws and screwdrivers at home, so it is equivalent to a disposable product, which causes inconvenience to users. Summary of the Utility Model

[0034] The following further elaborates on the present utility model in conjunction with the attached Figures 1-4 drawings.

[0035] As Figures 1 to 3 shown, this embodiment discloses a walker seat, including a seat board 1. A fastener 2 is provided on the back of the seat board 1, and a cushion layer is provided on the front of the seat board 1. The fastener 2 is provided with a card slot at one end far from the front of the seat board 1. The cross-section of the card slot is an arc structure greater than 1 / 2 and less than 3 / 4. The card slot is adapted to the first support rod 7 of the walker. Through the card slot of the fastener 2, the seat board 1 can be buckled and installed on the first support rod 7 of the walker. And due to the structure of the card slot, the seat board 1 can rotate around the first support rod. In this embodiment, two fasteners 2 are provided, and the two fasteners 2 are distributed on both sides of the back of the seat board 1 along the length direction of the first support rod 7. Through the setting of the two fasteners 2, the connection between the seat board 1 and the first support rod 7 is stable.

[0036] In this embodiment, the seat cushion plate 1 is an injection-molded plastic plate, and the seat cushion plate 1 is composed of transverse and longitudinal ribs. This makes the seat cushion plate 1 use less material and be light in weight, and also makes the seat cushion plate 1 provided with a plurality of through grooves penetrating the thickness of the seat cushion plate 1.

[0037] In this embodiment, the fastener 2 and the seat cushion plate 1 are of an integrally formed structure, or the fastener 2 is fixed to the seat cushion plate 1 by screws. Even if the fastener 2 and the seat cushion plate 1 are fixed by screws, when installing the fastener 2 on the seat cushion plate 1, there is no need to limit the position between the fastener 2 and the first support rod 7, so the installation is also very convenient. At the same time, when removing the seat from the walking aid, it only needs to pull the seat off the first support rod 7, without the need to install and remove screws, and can be reused.

[0038] In this embodiment, the cushion layer 3 includes a foam layer and a surface layer wrapping the foam layer. Through holes penetrating the thickness direction of the foam layer are provided on the foam layer. Through the through holes of the foam layer and the through grooves on the seat cushion plate 1, the ventilation of the seat can be realized. In this embodiment, the surface layer adopts a wrapped leather layer.

[0039] When installing the walking aid seat in this embodiment, by aligning the card slot on the back fastener 2 of the seat cushion plate 1 with the first support rod 7, the fastener 2 can be snapped onto the first support rod 7 through the card slot to complete the installation of the seat. When the walking aid is unfolded, by rotating the seat around the first support rod 7, one end of the seat is abutted against the second support rod 6. At this time, both ends of the seat are supported, and the user can sit on the seat.

[0040] When it is necessary to store the seat, only need to lift the seat against one end of the second support rod 6 and rotate the seat 90 degrees around the first support rod 7. When it is necessary to remove the seat from the walking aid, only need to force the card slot on the fastener 2 to disengage from the first support rod 7.

[0041] Embodiment 2:

[0042] The rest of this embodiment is the same as that of Embodiment 1, except that: in this embodiment, a connecting block 11 is further provided on the back of the seat cushion plate 1, and the connecting block 11 and the seat cushion plate 1 are integrally formed or connected by screws.

[0043] A buckle 8 is hinged on the connecting block 11. A first clamping portion 9 and a second clamping portion 10 are arranged on the buckle 8. In this embodiment, the cross-sections of the first clamping portion 9 and the second clamping portion 10 are also arc-shaped. When the walking aid is folded, the first clamping portion 9 is clamped with the unfolding rod 4 of the walking aid, and the second clamping portion 10 is clamped with the supporting rod 5, so that the unfolding rod 4 and the supporting rod 5 can be limited in position, preventing the unfolding rod 4 and the supporting rod 5 from disengaging, thereby realizing the stable connection of the folded walking aid. When the walking aid needs to be unfolded, the connection between the first clamping portion 9 on the buckle 8 and the unfolding rod 4 is disengaged, and the connection between the second clamping portion 10 and the supporting rod 5 is disengaged, and then the unfolding of the walking aid can be realized.

[0044] The above are all the preferred embodiments of the present invention, and the protection scope of the patent of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
