Description
The present invention relates to a brake device for a bicycle, and more particularly, to a brake device for a bicycle capable of operating the brake device by rotating a handle that is rotatably installed at both ends of the hand frame is installed on the handle frame. .
In general, bicycles are one of the vehicles that have been used for a long time, but the number of users decreased due to the power engine using fossil fuels such as automobiles in the industrial society, but in modern times, the information society, For the modern people who are lacking, they are attracting new attention as a means of leisure and sports.
Such a conventional bicycle is provided with front and rear wheels at the front and rear, respectively, the handlepost is connected to the shaft of the front wheel, and the handle is fixed at the upper end thereof, and the support frame is fixed between the handlepost and the rear wheel in the horizontal direction and downward, respectively. do. The saddle frame is fixed to the middle of the support frame, and the saddle is fixed to the saddle frame. The drive shaft is rotatably connected to the lower left and right sides of the center of the support frame, and the pedals are fixed to both sides of the drive shaft, the driving sprocket wheel is fixed to one side of the driving shaft, and the driven sprocket wheel is fixed to the rear wheel shaft. The chain is connected between the sprocket wheel and the rear wheel sprocket wheel.
Therefore, when the user rotates each pedal while sitting in the saddle, the drive shaft is rotated and the drive sprocket wheel is rotated together. At this time, the driven sprocket wheel which is connected to the drive sprocket wheel by the chain is rotated to generate a driving force, and the driving force can move forward without falling down.
In such a bicycle, the occupant in the saddle holds both handles with both hands and pedals with his feet to advance the front wheel and the rear wheel, and when moving forward, the steering wheel held by the hand is turned left and right. Will be converted.
On the other hand, while riding a bicycle to stop at a specific place, or sometimes urgent need to stop the bicycle often occurs. Thus, a brake device for stopping the bicycle is provided on the bicycle.
The braking device includes an operating lever provided on the handle, a brake provided on the front wheel or the rear wheel, for stopping the rotation thereof, and a cable connecting the brake and the operating lever.
In the conventional bicycle braking device as described above, braking is performed by using the finger to grab the operating lever while the steering wheel is wrapped with the hand, and it is inconvenient to operate the operating lever with a finger in a sudden situation, In the case of small and weak children or elderly people who lack hand biographies, it was difficult to suddenly brake in an emergency situation.
Therefore, the present invention has been made in order to solve the above problems, by embedding the operating unit for operating the brake unit in the handle frame, by operating the operating unit by the rotation of the handle to control the brake unit, such as emergency situation It is an object of the present invention to provide a brake system for a bicycle that can easily prevent the occurrence of an accident by braking the brake unit easily without being embarrassed.
The present invention for achieving the above object, the handle post is fixed to one end of the support frame vertically, the handle is provided rotatably at both ends of the handle frame is fixed to the handle post horizontally; A rotating member fixed to the handle, a screw screwed to the rotating member, the slider being reciprocated horizontally by the rotation of the rotating member, and having a protrusion formed at one side thereof, and the slider mounted on the inner side so as to be reciprocated. An operating part including a housing in which a guide groove is formed to guide the movement of the protrusion when the slider is reciprocated, and a return part for returning the handle to its original state; A braking part provided on the support frame to prevent the wheel from rotating; And a cable having one end connected to the braking part and the other end connected to the operating part to control the braking part by being pulled or pushed when the slider is reciprocated by the operation of the handle. A moving protrusion formed at an inner circumference of one end of the handle; A guide hole formed at a predetermined length in a circumferential direction at one end of the handle frame and communicating with an inner space of the handle frame to guide the movement of the moving protrusion; A fixing protrusion protruding from one end of the handle frame; And an elastic member connected between the fixing protrusion and the moving protrusion to elastically support the handle in the circumferential direction.

In addition, according to the present invention, the return portion is a fixing protrusion protruding from one end of the rotating member; A fixing part formed at an inner one end of a housing in which one end of the pivot member is rotatably supported; And an elastic body inserted into an outer circumference of one end of the rotation member, one end of which is fixed to the fixing protrusion, and the other end of which is fixed to the fixing part, and which is wound during rotation of the rotation member to accumulate an elastic force. It is done.
In addition, according to the present invention, the operation unit is mounted to the inside of the handle frame or handle, is fixed to the end of the rotating member is provided with a motor for rotating the rotating member, operation for operating the motor A button is provided on the handle or the handle frame.
According to the present invention, the handle frame has a built-in operation unit for pulling or pushing the cable for controlling the braking unit, and by operating the operation unit by the rotation of the handle, the user simply handles the handle when driving and stopping the bicycle. By controlling the braking device by rotating, it is possible to easily operate the braking device without embarrassment even in an emergency, thereby preventing the safety accident in advance.
