Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an option of a horizontal bar handle grip mounted on a bicycle handle grip of a wheelchair so that the wheelchair of the bicycle handle grip can be more easily operated by a pusher.

[0002]

2. Description of the Related Art Conventionally, most wheelchairs generally used are bicycle handle grips. The bicycle handle grip is suitable for the operation of lifting the wheelchair, but is unexpectedly inconvenient for the basic operation of the wheelchair such as pushing and pulling. If the pusher has no power, it is difficult to go straight for a long time whether pushing or pulling a wheelchair on a slope.

[0003]

This has the following disadvantages. (A) A bicycle handle grip of a wheelchair imposes a heavy burden on a weak pusher, whether pushing or pulling. (B) Since the bicycle handle grips are independent on the left and right, the pusher must always hold the left and right grips for stable wheelchair operation, and it is difficult to respond with one hand in an emergency. The present invention has been made to solve these disadvantages.

[0004]

SUMMARY OF THE INVENTION At one end of a pair of curved hollow shafts (3), a C-shaped wheelchair handle grip connecting portion (6) is provided. Then, a common connecting portion (4) that slides on the other end of the hollow shaft (3) is provided. One of the connecting portions (4) to be slid and the horizontal bar grip (1) are integrated with the shaft (2), leaving a space for the finger of the pusher to enter with a margin.
The present invention is a horizontal bar handle grip option for a wheelchair having the above-described configuration.

[0005]

Embodiments of the present invention will be described below. (B) A C-shaped wheelchair handle grip connection portion (6) is provided at one end of a pair of left and right curved metal hollow shafts (3). (B) Rubber (12) is applied to the inside of the connection part (6) of the C-shaped wheelchair grip, and further applied rubber (12)
Put a notch in the. (C) At the other end of the pair of curved hollow shafts (3), a common connecting portion (4) that slides left and right respectively.
And a set screw (5) for fixing the connecting portion (4) after sliding is provided at the center. (D) One side of the connecting portion (4) to be slid and the horizontal handlebar grip (1) are integrated with the shaft (2) with a space for the finger of the pusher to enter with sufficient margin. The present invention has the above structure, and when using this,
The C-shaped wheelchair handle grip connection portions (6) are respectively connected to the left and right bicycle handle grips of the wheelchair, and are securely fixed with the fasteners (7). At this time, in order to adjust to the width of the wheelchair handle grip, the sliding connecting portion (4) is slid and adjusted, and is fixed with the screw (5) at the center of the sliding connecting portion (4). The inside of the C-shaped wheelchair handle grip connection part (6) is provided with a notched rubber (12), so that it can be firmly fixed when fixing with the fastener (7). After fixing, the push bar can be pushed and pulled by the pusher grasping the horizontal bar handle grip (1).

[0006]

By mounting the horizontal bar handle grip on the wheelchair, the burden of force when the pusher pushes or pulls the wheelchair can be reduced. Also, the horizontal bar handle grip is located at the center of the wheelchair and is relatively stable even when gripped with one hand, as compared with the bicycle handle grip, so that it is easier to respond in an emergency. The original bicycle handle grip can be used as it is, and it can be used together with the attached horizontal bar handle grip, so the grip area of the pusher is widened, and wheelchair operation is more free and stable.
