It can be turned on, that is, can be turned on and a warning can be issued.

[0006]

[Embodiment of device]

  Hereinafter, referring to the drawings, a brake shoe for a bicycle with a warning device of the present invention will be described. A preferred embodiment will be described. As shown in FIG. 2, for bicycles according to the present embodiment The brake shoe 5 is pressed against the bicycle rim 3 (see FIG. 4) to stop the rotation of the wheels. For this purpose, it is attached to the brake arm 4.

[0007]   More specifically, this bicycle brake shoe is shown in FIGS. 3 and 4. The braking surface 51 that contacts the bicycle rim 3 and the opposite side of the braking surface 51. A connecting means 6 for connecting to the brake arm 4 is provided, and the brake is connected through the connecting means. The mounting surface 52 supported and fixed to the arm 4 and the mounting surface 52 and the braking surface 51 A shoe made of elastic material having a pair of corresponding side surfaces 53 interposed therebetween. A body 5 is provided. On the mounting surface 52, the mounting surface 52 and the mounting surface 52 A battery 71 having a pair of electrodes 712 and 711 arranged near the surface 52 is housed and opened. Two power feeding units 8 in which a closeable hollow space 81 is formed are provided. And before Inserted from the two side surfaces 53 by being inserted into the spaces 81 of the two power feeding portions 8 respectively. The first terminal pole 721 electrically connected to the electrode 711 near the surface 52 And is inserted into the space 81 from the side surface 53 to form a gap with the electrode 712 near the braking surface 51. The second terminal pole 722 facing each other and the first and second terminals. The electric poles 721 and 722 are electrically connected to the respective end portions on the side surface 53 side. Two warning devices 72 including a light emitting unit 723 are provided. In this embodiment Both of the two warning devices 72 are light emitting diodes (LEDs).

[0008]   In addition, the braking that abuts the rim 3 at a position of each braking surface 51 corresponding to the power feeding portion 8. Portions 511 are formed on each. Each of the braking units 511 has a corresponding power supply unit 8 A first annular groove 512 extending into the shoe main body 5, and the first annular groove 512. After the distance is increased, the space is further extended to the space 81 of the power feeding portion 8 and communicates with the space 81. Two annular grooves 515 are formed. Of the first and second annular grooves 512, 515 In the ring, the shoe is formed by the portion 514 that constitutes the distance in the shoe body 5. A push rod 513 connected to and held by the main body 5 is formed. In addition, shoe By increasing the frictional force when the body 5 contacts the rim 3, and by the friction of the shoe body 5. Three concave grooves 54 are formed on the braking surface 511 to absorb the thermal expansion. In addition, in each of the power feeding portions 8, so as to shield the opening 83 of each hollow space, The lid 9 is attached to the attachment surface 52 with screws 91.

[0009]   As shown in FIG. 5, when trying to brake the bicycle, the brake arm 4 is rotated. Bring it closer to the car rim 3 and press the braking part 511 of the braking surface 51 inside the bicycle rim 3. When the bicycle is braked, the pushing force of the push rod 513 is reduced by the reaction force from the bicycle rim 3. 1 toward the mounting surface 52, and the second terminal pole 722 is connected to the battery 7 1 is applied to the electrode 712 near the braking surface 51 to conduct the current of the battery 71, 23 can be illuminated, i.e., lit and alerted.

[0010]

[Effect of device]

  As described above, the bicycle brake shoe of the present invention attempts to brake the bicycle. The brake arm is brought closer to the bicycle rim, By pressing the bicycle rim, you can stop the rotation of the wheels. First, the reaction force from the bicycle rim causes the braking surface to move toward the mounting surface. And bend the second terminal pole against the electrode of the battery near the braking surface. The current of the battery can be conducted to cause the light emitting section to emit light. It can be lit and give a warning.
