Description

[Detailed explanation of the invention] This utility model is a walking aid used by people who have difficulty walking, such as the elderly or physically disabled people.It is designed to be disassembled for convenient transportation and storage, and to be easily assembled. This is what I did.

Conventional walking aids cannot be disassembled, so they take up a lot of space for transportation and storage, and when transporting an elderly or disabled person by car, a separate cargo vehicle is required to carry the walking aid, which is inconvenient. .

The present invention was devised to compensate for the above-mentioned drawbacks, and does not require a large space because it can be disassembled and transported in a car seat or trunk, and stored in a warehouse because it can be disassembled and stacked. Also,
It has the advantage of being easy to assemble anywhere.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the walking aid device according to the present invention, which can be disassembled and assembled, will be described in detail below with reference to the drawings.

FIG. 1 shows a walking aid device according to the present invention,
It is composed of a pair of left and right support legs 1, 1, and an upper connecting fitting 2 and a lower connecting fitting 3 that connect the left and right pair of supporting legs 1, 1 at a predetermined interval. The left support leg 1 is, as shown in FIG.
It consists of a horizontal support rod 1-3 located in the front-rear direction, and a support leg 1-1 extending downward from the horizontal support rod 1-3 and having a pair of front and rear casters 1-8, 1-8 at its lower end. At the front end of the horizontal support rod 1-3,
Upper connecting part 1- having a hole opening toward the front
It is equipped with 2. Further, the support shaft 1-1 of the support leg 1 is provided with a lower connecting portion 1-5 that protrudes upward at a lower position forward of the front end of the horizontal support rod 1-3. Note that the right support leg 1 has a structure similar to that of the left support leg 1 described above, so a description of its structure will be omitted. As shown in FIG. 3, the upper connecting fitting 2 has insertion fittings 2-3, 2- in the parallel parts at both ends thereof.
3, and is formed into a substantially U-shape, and the insertion fittings 2-3, 2-3 at both ends are connected to the upper connecting portion 1 of the horizontal support rods 1-3, 1-3 of the left and right support legs 1, 1.
-2, 1-2 from the front, the horizontal support rods 1-3, 1-3 of the left and right support legs 1, 1 are connected in parallel at a predetermined interval. Connected state (insert fittings 2- on both ends of upper connecting fitting 2)
3, 2-3 is the horizontal support rod 1- of the left and right support legs 1
3. In the state inserted from the front into the upper connecting part 1-2, 1-2 in 1-3), the horizontal support rod 1
-3, fixing screw 1-4 provided on the front part of 1-3,
By tightening 1-4, the connected state can be fixed. As shown in FIG. 4, the lower connecting fitting 3 has insertion fittings 3-6,
3-6, and is formed into a substantially U-shape, and the insertion fittings 3-6, 3-6 at both ends are connected to the lower connecting portion 1 of the support legs 1-1, 1-1 of the left and right support legs 1, 1. −
5, 1-5 from above to connect the supporting legs 1-1, 1-1 of the left and right supporting leg bodies 1, 1 in parallel with a predetermined interval. Connection state (insertion fittings 3-6, 3 at both ends of lower connection fitting 3)
-6 inserted from above into the lower connecting parts 1-5, 1-5 of the supporting legs 1-1, 1-1 of the left and right supporting legs 1), the fixings provided at both ends of the lower connecting fitting 3 The connected state can be fixed by tightening the screws 3-7, 3-7.

Next, the effect will be explained. When disassembling the walking aid device assembled as shown in Figure 1, use the fixing screw 1.
-4, 1-4, and pull out the upper connecting fitting 2 forward from the upper connecting parts 1-2, 1-2 of the horizontal support rods 1-3, 1-3 of the left and right supporting legs 1, 1. Loosen the fixing screws 3-7, 3-7, and attach the lower connecting fitting 3 to the support legs 1-1, 1 of the left and right support legs 1, 1.
Pull it upward from the lower connecting parts 1-5, 1-5 of -1. As a result, the walking aid device can be disassembled into four parts: the left and right supporting legs 1, 1, the upper connecting fitting 2, and the lower connecting fitting 3. Each part after disassembly, that is, the left and right support legs 1, 1, the upper connecting bracket 2, and the lower connecting bracket 3, has a thin and approximately planar shape, so they require a large space for transportation and storage. I don't.

To assemble the walking aid, just follow the steps in reverse. In this case, the upper connecting portions 1-2, 1-2 of the horizontal support rods 1-3, 1-3 on the left and right support legs 1, 1 are
Since the insert fittings 2-3 and 2-3 formed at both ends of the upper connecting fitting 2 are inserted into the -2 from the front and connected to each other, when the upper connecting fitting 2 is inserted and connected, This upper connection fitting 2
As a result, the horizontal support rods 1-3, 1-3 are connected while maintaining a predetermined distance from each other and maintaining parallelism in the front-rear direction.

In addition, the support leg 1- in the left and right support leg bodies 1, 1
Each of the lower connecting parts 1-5, 1-5 of 1, 1-1 is connected to each insertion fitting 3-6, 3-6 formed at both ends of the lower connecting fitting 3 to the said connecting part 1-5, 1-5. are inserted from above and connected to each other, so when the lower connecting fitting 3 is inserted and connected, the lower connecting fitting 3 connects the supporting legs 1-1,
1-1 are connected at their lower connecting portions 1-5, 1-5 while maintaining a predetermined distance from each other and maintaining parallelism in the vertical direction. That is, the left and right support legs 1, 1 of the walking aid machine in the assembled state
is connected to each horizontal support rod 1- by the upper connecting fitting 2.
3, a predetermined interval is maintained at the 1-3 portion and parallelism in the front-rear direction is maintained, and a predetermined interval is maintained at the lower front position of each supporting leg 1-1, 1-1 by the lower connecting fittings 3, 3. This maintains parallelism in the vertical direction. Therefore, the supporting legs 1, 1 of the walking aid device in the assembled state are firmly connected to each other by the upper connecting fitting 2 and the lower connecting fitting 3, making it possible to obtain a strong walking aid device. It can be done.

The walking aid device according to the present invention, which can be disassembled and assembled, is located in the front-rear direction and has an upper connecting portion 1-1 at its front end.
Horizontal support rod 1-3 with 2 and this horizontal support rod 1-3
A leg 1-1 extends downward from the horizontal support rod 1-1 and has a pair of front and rear casters 1-8, 1-8 at its lower end, and a lower connecting portion 1-5 at a lower position forward of the front end of the horizontal support rod 1-3. A pair of left and right support legs 1, 1 consisting of a pair of left and right support legs 1, 1 are formed into a substantially U-shape, and insert fittings 2-3, 2-3 at both ends thereof are connected to horizontal support rods 1-3 of the left and right support legs 1, 1. , 1-3 each upper connecting part 1-2,
1-2 from the front to connect the horizontal support rods 1-3, 1-3 of the left and right support legs 1, 1 in parallel at a predetermined interval; , is formed into a substantially U-shape, and the insertion fittings 3-6, 3-6 at both ends thereof are connected to the lower connecting portions 1-1 of the support legs 1-1, 1-1 of the left and right support legs 1, 1.
5, 1-5 from above to connect the support legs 1-1, 1-1 of the left and right support legs 1, 1 in parallel at a predetermined interval. Although it has an extremely simple configuration, it can be disassembled and assembled by an extremely simple operation of removing or inserting the upper connecting fitting 2 and lower connecting fitting 3 to the left and right support legs 1-1, 1-1. This has the excellent effect of reducing the space occupied by transportation, storage, etc., and providing a walking aid with excellent strength in its assembled state.
