Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire for a brake mounted on a fixed portion of a brake from a brake handle of a bicycle, a wheelchair or the like.

[0002]

2. Description of the Related Art A wheelchair brake is provided with a tackle brake at the front which is used by a rider to stop or fix the wheelchair, and a brake handle for a caregiver to be used at a rear handle of the wheelchair. Is attached to the handle. The brake handle attached to the rear handle of the wheelchair is connected by a wire to a drum brake or a caliper brake attached to wheels. The grip of the brake handle attached to this handle, that is, the strength of gripping the brake handle, is transmitted to the brake by a wire, and the wheels are braked.

[0003] Similarly, a bicycle also has a brake handle attached to the handle. The brake handle is connected to the caliper brake of the front wheel and the drum brake of the rear wheel by a wire, and the strength of gripping the brake handle is passed through the wire. The brakes are transmitted to the brakes to apply braking.

[0004] As shown in FIG. 1, in the case of a wheelchair 11, a conventional brake wire is connected to a brake handle 13 provided at a lower portion of a handle 12 so as to operate one end of a wire 14 for operating a drum brake 16. Is connected to the brake handle 13. At the other end of the wire, as shown in FIG. 2, a wire terminal processing unit 28 is fixed to the brake fixing unit 24.

As described above, one end of the wire is connected to the brake handle, and the terminal processing unit at the other end is connected to the fixed part of the brake. A bicycle rider or a caregiver operating a wheelchair operates the handle while holding the brake handle attached to this handle all the time to apply braking. The length of changes. Alternatively, when the wheels 15 are to be replaced, for example, the wire end processing unit 28 is removed from the brake fixing unit 24, then the wire fixing unit 27 is removed, and the wire is pulled out from the wire guide tube 22.

However, as shown in FIG. 4, when the wire 14 is detached from the fixing part 24 of the brake to which the terminal processing part 28 of the wire is fixed, the place where the terminal processing part 28 of the wire is fixed is removed. Since the wire 14 is crushed by caulking, when the wire 14 is used again, the wire 14 does not pass through the wire guide tube 22 and the fixing portion 24 of the brake, so that a new wire or a new terminal processing unit has to be used. Was the current situation.

[0007]

[Problem to be solved by the present invention] The present invention is to improve the terminal processing part of a wire connecting a brake handle and a brake of a bicycle or a wheelchair, to easily remove the wire when replacing the wire, and to reuse the removed wire. An object of the present invention is to provide a wire for a brake that can be used.

[0008]

In order to solve the above-mentioned problems, the present invention has been subjected to various studies, and as a result, by providing a detachable locking portion in the terminal processing portion of the wire, the wire is easy to remove and can be reused. It was able to be a wire for a simple brake.

As described above, according to the present invention, in order to operate a brake of a bicycle or a wheelchair, one end of a wire is connected to a brake handle and the other end is connected to a fixed portion of a caliper brake or a drum brake. A wire for a brake, wherein a detachable locking portion is provided in a terminal processing portion of a wire connected to a fixed portion of a caliper brake or a drum brake. The provision of the detachable locking part in the wire terminal processing unit makes it easy to attach the wire terminal processing unit to the brake fixing unit, makes it easy to remove, and enables reuse.

The brake wire according to claim 1, further comprising a length adjusting mechanism inside the terminal processing unit. By providing the length adjusting mechanism inside the wire terminal processing portion, when the brake handle is connected to the brake fixing portion, the bending of the wire can be eliminated, and the working condition of the brake can be adjusted.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described below, but the present invention is not limited to the following embodiments.

As shown in FIG. 3, the wire 100 of the present invention has a ring-shaped locking portion 23 as a locking portion that can be attached to and detached from the terminal processing portion of the wire. The locking portion 23 is passed through a bolt attached to the fixing portion 24 of the brake and fixed with a nut 26. The ring-shaped locking portion 23 can be fixed only by passing a ring through a bolt attached to the fixing portion 24 of the terminal processing portion and tightening the nut 26 from above. Further, the wire 14 is simply attached by fixing the wire guide tube 22 to the wire fixing portion 27, and the wire 14 can be easily removed only by removing the nut 26. Therefore, not only the replacement of the wire 14 is simplified, but also the wire 14 is not damaged and the wire 14 can be reused.

[0013] The shape of the detachable locking portion may be a key shape, or any shape that can be hooked on the bolt of the wire fixing portion of the brake and locked, and is limited to the above-described ring shape. It is not something to be done.

Further, in order to adjust the length of the wire 14, a nut 21 is attached near the inside of a terminal processing unit provided for hanging the wire fixing unit 27 in FIG. By moving the position back and forth, the length of the wire 14 can be adjusted. By simply adjusting the length of the wire in this way, a wire length adjustment mechanism has been provided that eliminates the bending of the wire and improves the braking effectiveness.

[0015]

[Effects of the Invention] By providing a detachable locking portion at the end of the wire, the wire can be reused as well as easily attached to and detached from the base of the brake. As a result, significant economic effects can be obtained in terms of time and cost. Further, by providing the wire length adjusting mechanism, there is an effect that a good brake can be maintained without bending the wire.
