Bicycle brake

This creation is related to brakes, especially with regard to a bicycle brake.

Press, the common bicycle brake system uses the friction between the brake block and the rim to stop the bicycle.

However, in the conventional bicycle brakes, in the event of an emergency, the brakes often lock the rim (ie, the rim does not rotate at all), causing the user to lose control of the bicycle, which is quite dangerous and may result in use. A bicycle brake that is injured by a fall, and generally has an anti-smashing car lock function, is disposed in a casing and uses a fastener extending from the casing to fix the brake pad in the casing, so that the user It is difficult to replace the components by themselves and replace the entire set of brakes in the event of a failure and use a brake pad holder of the same specification that can be matched with the housing, which is a waste of resources and money, and there is a drawback that needs to be improved.

Therefore, it is necessary to provide a novel and progressive bicycle brake to solve the above problems.

The main purpose of this creation is to provide a bicycle brake that prevents the brake from being locked, has a simple structure, is cost-effective, and is easy to disassemble.

In order to achieve the above object, the present invention provides a bicycle brake comprising: a clamp arm provided with a sliding slot; a brake assembly having a shaft portion slidably inserted in the sliding slot; an elastic member Abutting the clamp arm and the shaft portion, the shaft portion has a tendency to move normally in one direction.

The following is a description of possible implementations of the present invention by way of example only, and is not intended to limit the scope of the creation of the present invention.

Referring to FIGS. 1 through 6, there is shown a first embodiment of the present invention. The bicycle brake 1 of the present invention includes a clamp arm 2, a brake assembly 6, and an elastic member 9.

The clamp arm 2 is provided with a sliding slot 3. The brake assembly 6 is provided with a shaft portion 7 that is slidably inserted into the chute 3. The elastic member 9 abuts against the clamp arm 2 and the shaft portion 7 such that the shaft portion 7 has a tendency to move normally in one direction. Thereby, when the brake assembly 6 compresses the elastic member 9, the elastic member 9 can push the shaft portion 7 back, thereby causing the brake assembly 6 to perform an intermittent braking operation to prevent the brake from being locked.

In this embodiment, the brake assembly 6 includes a brake pad seating 8 and the brake pad seating 8 includes an actuator piece 80. The shaft portion 7 includes a protruding portion disposed on the brake pad mounting seat 8 and slidably worn. a shaft body 72 disposed in the sliding slot 3 and a moving seat 73 connected to the shaft body 72 and movable along the sliding slot 3, the elastic member 9 abutting against a side wall of the sliding slot 3 and the moving seat Between the 73, the brake pad seating 8 and the moving seat 73 are located on opposite sides of the sliding slot 3, whereby the clamping arm 2 does not need to be additionally provided for fixing the structure of the brake pad mounting seat 8 (for example, The brake assembly 6 can be positioned on the rail body 5 by enclosing the portion of the brake pad seating that prevents the brake pad seating from disengaging the clamping arm. The sliding slot 3 has a circular shape and is provided with a notch 32 facing away from the brake pad mounting seat 8. The movable base 73 includes a stop 75 and a slider 76 connected to the stop 75. The slider 76 is embedded in the slider 76. The chute 3 is slidable along the chute 3, and the stop 75 is blocked against the lip of the notch 32 to prevent the moving seat 73 from coming out toward the brake pad seating 8. The shaft portion 7 is provided with a screwing portion 77. A screw member 71 passes through the movable seat 73 and is screwed to the screwing portion 77 to strengthen the screw. Further, the tension of the screw member 71 can be adjusted by adjusting the tightness of the screw member 71. The degree of actuation of the resilient member 9 and the actuating assembly 6 is controlled (such as, but not limited to, tightening the tightness to increase the coefficient threshold for the force required to move the actuating assembly 6).

The clamping arm 2 includes a body 4 and a rail body 5 laterally connected to the body 4. The rail body 5 is provided with the sliding slot 3. A first card protrusion 31 is protruded from a side wall of the sliding slot 3, and a second card protrusion 74 is protruded from the moving seat 73. The elastic member 9 is a coil spring and the two ends are sleeved on the first and second cards. The projections 31, 74, whereby the elastic member 9 can be stably disposed in the sliding groove 3. The body 4 is provided with a through slot 41 transverse to the slot 3. The rail body 5 is provided with a guiding block 51. The guiding block 51 is embedded in the slot 41 and can be adjusted and positioned along the slot 41. The guide block 51 can help the rail body 5 not to disengage from the body 4, and the through slot 41 can be used to adjust the relative position of the alignment body to the rim 900. The rail body 5 includes two parallel opposing lugs 52. One of the lugs 52 is provided with the guiding block 51. The two lugs 52 are disposed on opposite sides of the body 4 and are positioned by a fastening member 53. The body 4, the clip 52 can help the rail body 5 to be stably positioned on the body 4. The body 4 further includes a track groove 42 that communicates with the through groove 41 and is laterally open, and at least one through structure 43. The guide block 51 can slide into the through slot 41 via the track slot 42 and then pass the fastening member 53 to bring the two clips 52 closer to each other to clamp the body 4, while the fastening member 53 can prevent the guide block 53 from being blocked. 51 is taken out of the through groove 41. The at least one through structure 43 can reduce the weight of the body 4.

In use, the clamp arm 2 is adjacent to the rim 900 and the brake pad 80 of the brake pad seating 8 contacts the rim 900. The brake pad seating 8 is driven in the direction of rotation of the rim 900. The elastic member 9 The brake assembly 6 is moved along the rail body 5 toward the first latch 31, and when the elastic force of the elastic member 9 is greater than the friction between the brake pad and the rim 900, The resilient member 9 pushes the moving seat 73 back toward the two ears 52, whereby the brake pad 80 can intermittently clamp the rim 900 instead of locking the rim 900. The brake pad seating 8 is independently connected to the movable seat 73 through the shaft body 72, so that the brake pad mounting seat 8 can be combined with the moving seat 73 using a conventional brake seat (the conventional brake seat is mostly provided with a The shaft body can be replaced by the user without replacing the entire set of the bicycle brakes 1 when the brake pad seating 8 needs to be replaced, which is quite cost-effective.

Referring to FIG. 7 to FIG. 10, in another embodiment, the rail body 5b has at least one turning portion 55b and is recessed toward the moving seat 73b, so that the brake pad mounting seat 8b is adjacent to the first engaging portion 31b. At the same time, it is away from the rim 900b, whereby the elastic member 9b can easily push the moving seat 73b back toward the two clips 52b to cause the brake assembly 6b to intermittently clamp the rim 900b. In other embodiments, the rail body may also be generally arcuate and concave toward the moving seat.

In other embodiments, the shaft body and the movable seat may be combined with each other, such as but not limited to using a cassette, except that the brake pad seating and the moving seat are located on opposite sides of the sliding slot. The body and the rail body may be combined with each other; the rail body may not be curved, and the brake assembly may be intermittently clamped when the brake pad is seated toward the first card. The first and second card protrusions may be recessed to allow the elastic member to be inserted into the cassette. Of course, the first and second protrusions are not limited to other types of the elastic member. In a manner, the elastic member can be placed in the sliding slot without being pulled out; the elastic member can also be disposed on the sliding slot near one end of the two clamping ears to change the moving seat toward the second in a normal state. Move in the direction of the clip.

In summary, the bicycle brake can achieve the purpose of preventing the brake from being locked by the action relationship between the elastic member and the movable seat. The brake pad mounting seat is detachably coupled with the movable seat. The brake is simple in construction, easy to assemble and disassemble, and cost-effective.
