Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a bicycle braking device that quickly dissipates heat generated during braking.

[0002]

[Prior art]

 Conventionally, the brake clip cushion structure, which has been used as a bicycle brake, has a flat cushion formed by joining the cover piece and the cushion.When braking, the entire rectangular cushion contacts the metal wheel at once. And braking.

[0003]

[Problems to be solved by the invention]

 However, since the wheels are completely stopped instantaneously, the inertia effect exerts an influence on the people and the bicycle, causing the wheels to continuously move forward. At this time, a long distance friction occurs between the tire sandwiched between the brake parts and the ground, and the tire is thereby damaged, and the slip of the rear wheels tilts the entire vehicle body. Furthermore, the steering wheel of the user becomes unstable, or the user unconsciously loosens the brakes in a hurry, eventually leading to an accident. Also, if the front and rear cars cannot be avoided, they will collide and lose valuable lives.

In addition, since the brake operation of the brake clip cushion utilizes the entire rectangular area of the cushion and comes into contact with the metal wheel of the tire at a time, the amount of wear due to the friction of the cushion is very large, and it is constant for a very short period of time. Must be replaced via Therefore, the economic burden on the user is increasing. In order to solve the above-mentioned problems, an object of the present invention is to provide a bicycle brake device that quickly dissipates heat generated during braking and is less likely to cause slippage.

[0005]

[Means for Solving the Problems]

 According to the bicycle brake device of the first aspect of the present invention, the bicycle brake device has a brake unit piece which is located on both sides of a metal wheel and is in close contact with the wheel and used for braking. The brake unit piece is provided with a cover piece and a brake block connected to the cover piece by screws. The brake block is formed with a plurality of grooves and a plurality of paragraph-shaped blocks, and the surface of the block which is in close contact with the wheel is formed with inclined surfaces having different thicknesses on both sides. As a result, when the brake operation is performed, the contact area between the brake block and the wheel gradually increases, so that the heat generated during braking can be quickly dissipated and the slip can be suppressed.

According to the bicycle brake device of the second aspect of the present invention, the brake block has a plurality of separated blocks, and the surface where each block and the wheel are in close contact is planar. . An undulation is formed at one end of the surface in contact with the cover piece, and a through hole is formed at the other end. Since the inclined surface can be formed by connecting the hole provided in the cover piece and the through hole of the block body with a screw, the same effect as the bicycle brake device according to the first aspect can be obtained.

[Embodiment of the invention]

 As shown in FIGS. 1 and 2, the bicycle brake device of the present invention is located on the left and right sides of a metal frame 111 of the front and rear wheels 11 of the bicycle 1. The brake is configured by combining a cover piece 4 and a brake block 2 connected by screws 3. The brake block 2 has a plurality of grooves 21 and a plurality of paragraph-shaped block bodies 22, and both sides of each block body 22 form an inclined surface 221 having a suitable height.

Next, the situation of running a bicycle after the installation of the above structure is shown below. In a situation where it is necessary to stop the bicycle by braking, the brake 1A is brought into close contact with the metal wheel 111 of the wheel 11 to perform the brake operation as in the normal case. At this time, since the surface of the brake block 2 in the brake 1A is an inclined surface 221 having an appropriate height, the thick portion first contacts the metal wheel 111 of the wheel 11 as shown in FIG. Start the deceleration of 11, and gradually reduce the speed. Subsequently, the contact area of the wheel 11 with the metal wheel 111 gradually increases, and as shown in FIG. In this way, heat generated during braking is quickly dissipated, and effects such as not causing a slip phenomenon are achieved. At the same time, at the moment of the braking operation, the contact of the thick part gradually reduces the speed of the bicycle, so that the inertial force generated by the instantaneous braking disappears. Subsequently, the thin portion and the thick portion are completely adhered to the metal wheel 111, and the vehicle can be easily stopped. In this way, the braking with the conventional brake clip cushion system exerts a centrifugal force on people and vehicles, which can be continuously urged forward to improve the risk of slipping, and subsequently to reduce the risk of slipping. It is possible to prevent the occurrence of an accident that is caused. Further, since the inertial force has been eliminated, the brake block 2 can easily reduce the speed of the bicycle at the shortest distance and stop the bicycle. It also eliminates the possibility of causing a long distance friction with the ground after braking and thereby damaging or slipping of the rear wheels tilting the entire vehicle body.

In addition, since the area of the brake block 2 that is worn can be reduced, the life of the tire and the brake block 2 can be extended, and the economic burden on the bicycle owner can be reduced. Further, the water droplets can be guided and drained by the grooves 21 of the brake block 2 in a timely manner, so that the influence of the water film can be suppressed to a low level.

Further, in the present invention, as shown in FIG. 5, the brake block 2 in the brake unit piece can be formed into a plurality of separated block bodies 23. As shown in FIGS. 5 and 6, each block body 23 has a flat surface 231 on one surface, and an undulation 232 on one side, and a through hole 233 on the other side. , Are connected by screws 4A at holes 41 on the cover piece 4. As shown in FIG. 7, the inside of the brake block 2 forms an inclined surface when combined with the cover piece 4.

With such a structure, the function of the brake block 2 as shown in FIG. 1 is formed, and the heat generated during braking is quickly dissipated, and effects such as not causing a slip phenomenon are achieved. .
