Abstract

To provide a brake device which has such a structure that a grip end of a bicycle handle bar is partially bent, tows a brake wire, can instantly apply a brake without requiring a strong force, and facilitates operation.SOLUTION: A brake device can pull a wire 6 by bending a grip 1 at the time of brake, and can operate a brake mounted on the tip of the wire 6.SELECTED DRAWING: Figure 3

Description

The present invention is an easy-to-operate and safe braking device that has a structure in which the grip end of the bicycle handlebar is partially bent, the brake wire is indexed, and the brake can be applied instantly without requiring strong force.

In the conventional bicycle braking device, the type of brake that grips the lever attached to the tip of the handlebar is easy to operate and can be applied safely.

However, in the conventional type of brake that grips the bicycle brake lever, it is necessary to pull the lever toward the grip side by the grip strength of the finger that grips the brake lever to operate the brake. Therefore, small children and elderly people who have difficulty applying force to their fingers require a great deal of grip to apply the brakes, and when braking, they take their fingers off the handle, put their hands on the brake lever, and then pull the lever. It takes time for the bicycle to start to work, and the free running distance becomes long until the bicycle brakes. In addition, it has been difficult for a person with a disability such as a finger defect due to a natural disability or an acquired accident to apply the brake of a bicycle with a lever, which is currently common.

According to the present invention, by bending a part of the grip end of the left and right handlebars of the bicycle, the brake wire can be pulled and the brake can be easily operated without requiring a strong force.

In this invention, since the bicycle does not have a conventional brake lever, the rider who feels the need for braking does not have to take his finger off the handlebar for a moment and grasp the brake lever when applying the brake, and the free running distance of the bicycle is shortened. The time required to stop braking can be significantly shortened as compared with the conventional brake device with a lever. In addition, even a person who has a missing finger or a part of the arm due to a natural disability or an acquired accident can operate the handle by fixing the tip of the arm or artificial hand to the hand grip with magic tape or the like. , The brakes can be applied, and people with disabilities can use the bicycle in the same way as healthy people. Further, by putting a cover on the brake operation portion, it is possible to protect the moving part of the brake device from rain, prevent rust, and delay the wear of the device.

It is the figure which looked at the bar handle of this invention from the front. It is the figure which bent the end grip of this invention, pulled a wire, and actuated a brake. It is an enlarged view of FIG. 2 of the present invention, and is the most important diagram showing the principle of the present invention. It is a reference figure when the wire of this invention is stored in a handlebar. It is sectional reference view when the wire of this invention is housed in a handlebar. It is a reference figure of the cross-sectional part when the wire of this invention is housed in a handlebar.

By bending the handlebar held by the driver who feels the need for braking while riding the bicycle, the bicycle can be braked.
The handlebar body ▲ 2 ▼ and the handlebar grip end ▲ 1 ▼ are connected by a hinge ▲ 4 ▼, and between the handlebar body ▲ 2 ▼ and the handlebar grip end ▲ 1 ▼, the handlebar body ▲ 2 The receiving part ▲ 7 ▼ on the outer circumference of the brake wire and the grip end ▲ 1 ▼ of the handlebar are equipped with the brake wire end receiving part ▲ 8 ▼, and the brake wire ▲ 5 ▼ is connected. By bending the grip end ▲ 1 ▼ of the handlebar, a gap is created between the handle body ▲ 2 ▼ and the grip end ▲ 1 ▼ of the handlebar, and by creating the gap, it can be pulled by the brake wire.
The shape of the handle body can be applied to any type such as drop handle, land bar type and so on.
Normally, if there is no brake wire body ▲ 5 ▼, it will be in a broken state. However, since the spring of the brake body operates on the upper part of the grip end ▲ 1 ▼ of the handlebar of the present invention, the brake wire body ▲ 5 ▼ is pulled by the spring of the brake body, and the handlebar body ▲ 2 ▼ and the handlebar The grip end ▲ 1 ▼ always forms a straight line.
Further, in the unlikely event that the brake wire ▲ 5 ▼ is stretched, the grip end ▲ 1 ▼ of the handlebar hangs down by the amount of the wire stretched, and the stretch of the wire can be found.
The working part of the present invention has many protrusions and can be touched with bare hands, but a cover can also be attached. In addition, all the structures of the present invention are housed in the handlebar body ▲ 2 ▼ and the handlebar grip end ▲ 1 ▼, and covered with various materials such as silicone rubber and plastic to hide the moving parts from the rain. It can contribute to the prevention of rusting of the wire and finger clogging.
