Abstract

(57) [Summary] [Objective] The present invention offsets the casters of the wheelchair to the outside to improve stability and eliminate steps as much as possible.
A footrest was installed inside the frame to save space. [Construction] The present invention offsets the 5 caster posts of the wheelchair frame to the outside and connects the 5 caster posts to the 7 seat support pipes. Bend the pipe side, 1 base pipe is connected by bending the 5 caster post side and eliminating the step as much as possible to improve stability, and 4 foot rests in the inner space created by offsetting the 5 caster post to the outside It can be installed and shortened in total length, which saves space and helps reduce the physical burden when loading it on a car.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wheelchair that is used by people with disabilities.

[0002]

[Prior art]

 In Japan today, the number of people with disabilities driving their own cars is increasing year by year. According to such changes in lifestyle, the stability when moving from a wheelchair to a car by a disabled person or conversely when transferring from a car to a wheelchair, and when a disabled person tries to mount a wheelchair on a vehicle In the case of a conventional wheelchair, there are steps and protrusions that occur due to structural and shape problems, and improvement is desired.

[0003]

[Problems to be solved by the device]

 For the purpose of productivity, the conventional wheelchair has a frame composed of a straight pipe and a pipe with a small bending radius, a caster is located on the outside of the front part, and a footrest is attached so that it protrudes from the frame forward. Loading and unloading is a heavy physical burden and requires space.

[0004]

[Means for Solving the Problems]

 Based on the current situation as described above, the present invention devised the structure of the frame, which was the largest protrusion of the conventional wheelchair, to be mounted inside the frame to make it compact and eliminate steps as much as possible. It is intended to eliminate the above-mentioned drawbacks

[0005]

[Action]

 The wheelchair of the present invention has improved stability by offsetting the casters to the outside of the frame to extend the stability, and the footrest is attached to the space provided by the extension to make the space in the length direction compact and the casters that extend. The purpose of this is to save physical and space-saving labor when mounting on a car etc. by connecting the frame with a mildly curved pipe and eliminating the step.

[0006]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. First, in the conventional wheelchair, 1 base pipe is connected to 2 caster post support pipes at a right angle, and is further composed of straight lines until it is connected to 3 leg pipes, and 4 footrests are attached to the lower ends of the 3 leg pipes. There is. Then, 5 caster posts are welded outside the intersection of the 1 base pipe and the 2 caster post support pipes. Due to this structure, the four footrests are located in front of the universal swing wheel (casters).

On the other hand, according to the present invention, the lower part of the 2 caster post support pipes is bent outward in a loose S-shape and connected to 5 caster posts, and the 1 base pipe is also bent from 5 caster posts to the outside. It is connected to the inside of the caster post. A 6-leg support pipe is connected from the front of the 5 caster post, and the front end is bent inward to connect to the 3-leg pipe.

[0008] In the present invention, the structure in which the 5 caster posts that are closely attached to the outside of the intersection of the 1 base pipe and the 2 caster post support pipes are closely attached to the outside is adopted in the present invention, so that the space inside the front of the 5 caster posts It was possible to find out, and in that space, the 4 footrest, which was located at the lower end of the 3 leg pipe in the conventional type, could be moved into the frame, and the total length of the wheelchair could be made compact.

[0009]

[Effect of device]

 As mentioned above, the wheelchair of the present invention has improved stability by offsetting the casters to the outside, and the footrest is mounted inside the frame to make it compact in the entire length direction, eliminating steps to save space, and physical work when loading and unloading. Useful for labor saving.
