Abstract

The invention relates to a switch control device for a bicycle brake light. It comprises a body (1) which contains a sleeve (2) in which a sleeve (3) can slide under the action of a brake cable held in a flange (10) fixed to this sleeve (3), in order to cause the closing and opening of a circuit comprising conductive blades (8) with spring and a conductive tube (5). An insulating block (6), movable with the sleeve (3), allows the blades (8) to bear against the tube (5) when traction is applied to the brake cable. Area of application: bicycles.

Description

The bicycle has been used as a transport vehicle since

  that it was created. In recent years, in advanced countries, to save energy, many people use a bicycle for short-distance travel instead of a motorized transport vehicle and, moreover, currently, the bicycle is widely available. used as an activity

outdoor sports.

  Although the bicycle is widely used

  In all countries, there are still some criteria

  the safety of a bicycle trip. As a result of rapid advances in technology, the bicycle, by design, has become less bulky and lighter. However, the stop warning devices have been able to evolve. Although various types of bicycle tail lamps are commercially available, or various types of reflectors to be glued on the rear portion of a bicycle are used, these bicycle rear lights or reflectors simply indicate where the bicycle is and not can not be used to simultaneously warn of braking. In addition, few countries have ever bothered to teach people how to ride a bicycle. As far as young people or children are concerned, they may have little knowledge of the rules of the road code. Since on a bicycle nothing protects the cyclist, it is actually dangerous to ride a bicycle at night. Since a bicycle is very light and its speed is low, while driving on a road, it may be struck by a motorcycle or automobile arriving in

  high speed from behind, causing an accident.

  Therefore, one of the best methods of protecting a cyclist is that the cyclist has a bicycle equipped with a means of warning motorcyclists or motorists arriving from

  the rear and indicating when the bicycle stops.

  The invention provides a bicycle brake light switch control device comprising a housing that includes a support plate for carrying a cable brake guide and coupling with a guide brake flange. cable, and having an internal thread for connection to the external thread of a socket; a bushing having an external thread for connection to the internal thread of the body and having two elongated openings formed on its two side walls, and an inner pillar projecting downward from the upper portion; a sliding sleeve having two circular grooves for mounting on this sleeve, two retaining rings, watertight, the sleeve having two positioning holes at the lower end for fixing an electric mount, two nozzles retainers for connection to the two elongated openings of the socket, respectively, a cable flange support plate at the bottom for holding a cable flange, the support plate having a screw hole made at its upper surface and having side wall plates for guiding and holding a cable flange in position, and two locating ribs formed on its inner hole to establish the position of a plurality of component parts; a conductive tube made of a conductive metal, having a

device according to the invention.

  Referring to the drawings, a brake light control switch device for a bicycle according to the invention comprises a body 1, a bushing 2, a sliding sleeve 3, retaining rings 4, a conductive tube 5, an insulating block 6 , a spring 7, conductive blades 8 spring, an electric mount 9, a

  flange 10 of cable and a flange 11 of cable guide.

  The body 1 comprises a support plate 101 for holding the cable guide 12 of a bicycle brake (see FIG. 3). The bushing 2 is screwed into the body 1 by means of a screw joint, comprising a pair of elongated openings 201 made in two side walls, and an inner column 202 protruding

  downward from the top (see Figure 3).

  The sliding sleeve 3 has two circular grooves 301 in which are intended to be mounted two water-tight retaining rings 4 in order to prevent the infiltration of water inside the device, which infiltration of water could otherwise impair the quality of electrical conduction or cause a short circuit. In addition, two positioning holes 305 are provided at the lower end for fixing the electric mount 9. The sliding sleeve 3 is slidably housed in the sleeve 2, so that its two retention spouts 302 are respectively disposed in the two elongated openings 201 of the sleeve 2. The sliding stroke of the sleeve 3 inside the sleeve 2 is limited by the two elongated openings 201. The sliding sleeve 3 also comprises a plate 306 intended to support the flange 10 cable, the support plate 306 having a screw hole 307 and having side wall plates 308 for guiding and maintaining the position of the cable flange 10. Two positioning ribs 304 are provided in the inner hole 303 of the sliding sleeve 3 in order to

  retain the inner component parts.

  The electric mount 9 has two notches 901 each located on one of its sides and intended for

  be connected to the two conductive blades 8 spring.

  Each spring conductor blade 8 has a bend 801 at its upper end and at its lower end a portion 802 for connecting with a corresponding power supply wire. During assembly, the conductive tube 5, the insulating block 6, the spring 7 and the electric mount 9 are placed respectively in the appropriate order in the inner hole 303 of the sliding sleeve 3 in a manner leaving the nozzles 902 retaining the electric mount 9 to fit in the holes 305 of

  positioning of the sliding sleeve 3, the upper rods

  upper and lower 601 of the insulating block 6 being inserted into the inner hole 501 of the conductive tube 5 and the spring 7, respectively. The insulating block 6 comprises a conical medial portion 602 allowing the elbow 801 to

  each conductive blade 8 with vertical sliding spring

  along the length of this part.

  The cable flange 10 has an elongate slot 1001 for mating with the cable flange support plate 306. A screw 309 is intended to be screwed into the screw hole 307 and the elongate slot 1001 connects the cable flange 10 to the support plate 306, allowing the flange 10 to be slidably adjusted in its horizontal position against the cable 13. When the cable 13 is inserted into the hole 1002 for the passage of the cable of the flange 10, it is clamped by means of a screw 1003 (see FIG.

Figure 3).

  The flange 11 of the cable guide is intended to clamp the brake cable by means of a screw 1102, which brake cable is not retained by a cable guide 12 and is mounted on the support plate 101 of the flange. of the cable guide of the body 1 by means of the groove 1101 (see figures

6 and 7).

  The external appearance of the assembly is as shown in Figure 2 and its operation is as shown in Figures 3 and 4. The guide 12 of the cable is fixedly connected to the support plate 101 of the body 1 by means of its adjusting screw. The cable 13 is firmly clamped by the flange 10. At this moment, the two conductive blades 8

  springs are not in contact with the conductive tube 5.

The circuit is open.

  With reference to FIG. 4, during braking, the cable 13 is driven in such a way as to force the sliding sleeve 3 to move towards the inside of the bushing 2 so as to allow the two conductive spring blades 8 to enter. in contact with the conductive tube 5. Therefore, the spring blades 18 close the circuit and the

brake light comes on.

  control of the brake light of a bicycle according to the invention

  mounted on a first type of brake.
