Abstract

To provide a wheelchair towing tool that is less likely to become an obstacle at the time of non-use and can readily tow a wheelchair at the time of use.SOLUTION: A wheelchair towing tool includes: a fitting member detachably fixed to a wheelchair; and a straight bar-like towing member fitted to the fitting member and a towing member that is a substantially L-shaped tip of the towing member. The towing member can be readily detached from the fitting member by being pulled up in a vertical direction.SELECTED DRAWING: Figure 1

Description

The present invention relates to a wheelchair traction device.

"Patent Document 1" to "Patent Document 6" as a device for pulling and assisting wheelchairs during emergency evacuation such as a disaster, or when wheelchairs are moving on rough terrain such as gravel roads or uphill. The wheelchair pulling aid disclosed in the above is known. These wheelchair pulling aids include a Kaji rod for pulling the wheelchair and a pair of left and right first attachment members for detachably attaching the Kaji rod to at least one of the left and right front pipes and the left and right leg pipes of the wheelchair. The first mounting member is configured so that the angle formed by the Kaji rod and the horizontal plane can be changed.

The prior arts of the above-mentioned "Patent Document 1" to "Patent Document 6" are all related to a wheelchair traction tool, but the structure is complicated, and it is troublesome to attach / detach the wheelchair traction tool to the wheelchair. , The cost of the parts is also high, so its usefulness is lacking. Therefore, the current situation is that none of them have been accepted by Ichii.

In view of the above situation, the present invention provides wheelchair movement support that can easily support emergency evacuation in the event of a disaster, running on rough terrain such as sand, snowy roads, gravel roads, and swamps, and running and moving wheelchairs on uphill slopes. The purpose is to provide the ingredients.

Furthermore, the main purpose of solving the problem is to make it easier for Ichii to accept, and we think that we can reduce the labor of attaching and detaching the wheelchair traction tool and reduce the price offered to the market. Therefore, it is necessary to reduce the cost.

The present invention has decided to solve the above problems by the following means.
(1) As the first means
In order to achieve the above object, the wheelchair movement support tool of the present invention has a pair of left and right mounting members that can be detachably attached to at least one of the left and right front pipes or the left and right leg pipes of the wheelchair, and the pair of mounting members thereof. The structure is characterized in that a traction member having a substantially L-shaped tip portion is inserted into the member.

(2) As a second means
A straight tubular traction member attached to the mounting member and a traction member having a substantially L-shaped tip of the traction member are provided, and the straight tubular traction member can be easily pulled up from the mounting member in the vertical direction. It is a wheelchair traction tool characterized by having a structure that can be attached and detached from the mounting member.

(3) As a third means
Since the traction member is towed in the horizontal direction, that is, no force is applied in the vertical upward direction, it is unlikely that the traction member will be easily removed from the mounting member by the traction force in the horizontal direction. It features a structure of a traction tool for wheelchairs that allows the insertion-type lock pin for preventing falling off to be easily inserted so that it does not easily come off when mounted.

It is an overall view which attached the wheelchair traction tool of the Example of this invention to a wheelchair. It is a state diagram which attached the attachment member of the wheelchair traction tool of the Example of this invention to a wheelchair. FIG. 2 is a state diagram in which the towing member is inserted into the attachment member of the wheelchair towing tool shown in FIG. It is a side view of the actual situation in which the traction tool for a wheelchair of the present invention is attached to a wheelchair and used.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an overall view of a wheelchair traction tool according to an embodiment of the present invention attached to a wheelchair, and is composed of a traction member 2 and an attachment member 3 as shown in FIG.
As shown in FIGS. 2 and 3, the mounting member 3 is mounted by being sandwiched between the wheelchair 1 by two mounting bolts 4. The mounting member 3 is provided with a pipe 5 for inserting the traction member 2 so that the traction member 2 can be inserted in a sliding state. Further, as shown in FIG. 3, an insertion type lock pin 6 for preventing falling off is inserted.

Examples are as shown in FIGS. 1, 2 and 3.

The fall-out prevention lock pin 6 is inserted into the through hole of the portion through which the traction member 2 is passed in the sliding (sliding) state inside the insertion pipe 5 of the mounting member 3. A bolt that substitutes for the function of the lock pin 6 may be screwed in.

The wheelchair traction tool according to the present invention can safely tow a wheelchair, easily support emergency evacuation in the event of a disaster in a wheelchair, traveling on rough terrain, or traveling uphill, and is convenient and short for a wheelchair. It has the effect of being installed in time and being able to be stored without taking up space.
