JP2002301110A - Wheelchair with backing type tilting function and aid thereof - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide tilting function to an ordinary commercially available foldable wheelchair by simple modification or additional application. SOLUTION: A rear wheel grasping part 1 is detachably mounted between major wheels (W1, W2) of the wheelchair through a fixing member 2 and a front wheel grasping part 5 is mounted near the front wheels of the wheelchair while a triangle support part 7 is mounted on the grasping part 1. A stretching means 6 for supporting the wheelchair is mounted between the front tip part of the triangle support part 7 and the front wheel grasping part 5 thereby providing a backing type tilting function.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can be easily mounted on a folding wheelchair which is generally available on the market, and when the wheelchair is not tilted, the wheelchair can be tilted without occupying the working space of a caregiver. The present invention relates to a wheelchair and an assisting device which can be easily and tilted and fixed at an arbitrary angle and can be moved while maintaining the state.

[0002]

2. Description of the Related Art Conventionally, an improved wheelchair of a reclining type or a tilting type as disclosed in Japanese Patent Application Laid-Open No. 06-121814 is known, but most folding wheelchairs on the market generally have a tilting mechanism. I do not have it.
In addition, there is no tilt aid that can be attached to or detached from a wheelchair that is commercially available.

[0003]

In the case where a wheelchair having no tilt function is provided by a simple modification of a wheelchair which does not have a tilt function, and a wheelchair which does not already have a tilt function is owned, By retrofitting it, it is possible to easily add a tilt function,
It is possible for a wheelchair owner who does not have a tilt function to add a tilt function to a general commercial folding wheelchair by retrofitting it to an existing wheelchair without purchasing a new tilt type wheelchair. Aids are eagerly needed.

[0004]

According to the present invention, a rear wheel holding portion 1 is provided between a large wheel (W1, W2) of a wheelchair via a fixing member 2.
The front wheel holding portion 5 is mounted near the front wheel of the wheelchair, and the triangular support portion 7 is mounted on the holding portion 1 of the wheelchair. By mounting the telescopic means 6 for supporting the wheelchair between the wheelchair 5 and the wheelchair 5, it is possible to obtain a wheelchair having a supportive tilt function, particularly a foldable wheelchair having a supportive tilt function. The present invention also relates to a wheelchair wheel (W
1, W2) has a rear wheel holding portion 1 detachably mounted via the fixing member 2 and a front wheel holding portion 5 mounted near the front wheel of a wheelchair. Wearing
An auxiliary device for adding a tilt function that can be easily attached to and detached from an existing wheelchair, which is provided with an expansion / contraction means 6 for supporting a wheelchair mounted between the front end portion of the triangular support portion 7 and the front vehicle holding portion 5. It is possible to provide.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings. 1 to 4 show an embodiment of the present invention. In FIG. 1, large wheels W1 and W of a wheelchair are shown.
2 is fixed to the large wheel fixing member inside the rear wheel 2 by using the sliding fixing member 2 of the rear wheel holding portion 1. The holding portion 1 is connected to a triangular support portion 7 that supports a load when the wheelchair is tilted.

[0007] The triangular support 7 is equipped with a plurality of auxiliary wheels 3 which also serve to prevent falling and to move. In the present embodiment, the triangular support portion 7 is described as being integral, but this is because the bottom member 8 for attaching the auxiliary wheel, the front and rear oblique members 9 and 1
It may be configured to be divided into 0. In this case, storage and carrying when the auxiliary tool is removed from the wheelchair can be performed more easily. Further, in the present embodiment, an example is shown in which two auxiliary wheels are mounted on one (number) of the triangular support portions 7, but the number of the triangular support portions 7 is two (or more).
Further, the shape of the support portion is not limited to a triangle, and may be a triangular pyramid or a quadrangular pyramid. In this case, three or more auxiliary wheels or a plurality of supports for the purpose of preventing falling without auxiliary wheels are attached, and the sense of stability is further improved.

One end of an expansion / contraction means 6 for supporting a load when the wheelchair is tilted is connected to the front end of the triangular support 7 so as to be capable of rotating with one degree of freedom. The upper side (the other end) of the expansion / contraction means 6 is connected to the front vehicle holding portion 5 so as to be rotatable with one degree of freedom.

This front wheel holding portion 5 includes front holding bars 12 and 2
The front holding and fixing members 4 are provided. The front clamping fixing member 4 is connected to both ends of the front clamping bar 12.

In this embodiment, the expansion / contraction means 6 is a piston-like expansion / contraction body, but may be replaced with a connecting rod or a screw type whose height can be adjusted by a pin or a spring.

The front holding and fixing member 4 is fixed with a screw or the like in front of a foot rod T for lifting a front wheel of a wheelchair.

As described above, according to the present invention, a tilt function can be added to an existing wheelchair by modifying a commercially available wheelchair or retrofitting an auxiliary tool, so that the existing wheelchair can be easily inclined. Since it is possible, it can be converted to a wheelchair having a tilt function. In addition, the device (assisting device) for adding the tilt function fits under the seat of the wheelchair even when attached, and does not hinder the actions of the caregiver and the care receiver. Further, it is possible to move while maintaining the tilt state. Moreover, since the device (assisting tool) for adding the tilt function can be easily removed, the device can be folded and carried together with the wheelchair by transferring to a conventional moving means.
