Description

[Detailed Description of the Invention] This invention relates to a switch device for a flash lamp for a bicycle.

Bicycles are usually equipped with turn signals that flash by selectively operating flash lamps located on the left and right sides of the vehicle body using a switch located near the driver's seat.

These turn signals serve as signal lights that indicate changes in the vehicle's course, and are of great use in ensuring safe passage of vehicles.

However, the prevalence of such turn signals on bicycles is extremely low.

When targeting bicycles, the conditions for widespread use are that they have a simple structure, are easy to operate, and are inexpensive.

In particular, the switch mechanism in the construction of the direction indicator must meet the above conditions.

This invention was made to solve the above-mentioned problems, and its main purpose is to provide a flash lamp switch device suitable for bicycles.

Hereinafter, this invention will be specifically explained based on drawings showing an example of its implementation.

In the drawings, 1 is a container housing a switch mechanism, and this container 1 is formed by overlapping two boxes 1a and 1b.

A support shaft 2 is rotatably supported through a central lower part of the container body 1, and a base end portion of a switch operation lever 3 that can swing from side to side about this support shaft is fixed to the support shaft 2. The tip of the lever 3 projects outward through an elongated hole 4 made in the top plate of the box 1a, and a knob 5 is attached to the projecting end.

The lever 3 has suction cups 6 on both sides in the swinging direction.
6 are fixed respectively.

In the normal state, the lever 3 is attached to a spring 9 that is hooked to the support shaft 2, the protrusion 7 on the lever side, and the protrusion 8 on the box 1a side.
Due to the elastic action of the lever, the lever is held at the center position of the swing angle, that is, at the neutral position.

Inside the container body 1, there is a receiving plate 10 for attracting the suction cups 6 on the lever side when the operating lever 3 is swung left and right.
．． 10 are arranged in a V-shape with the support shaft 2 as a fulcrum.

Each receiving plate 10 has a hole 11 penetrating through the receiving plate in the suction plate portion of the M6 suction plate, and a screw 12 communicating with the hole 11 is fixed to the opposite plate surface, and a screw plug 13 is fixed to this plate. is screwed, and the screw gap formed by the screw plug 13 and the screw thread 12 is used as a narrowed air passage, and the suction negative pressure chamber 14 of the suction cup 6 is connected to the outside through this narrowed air passage and the air hole 11. will be contacted.

A switch plate 15 made of an electrically insulating material is disposed within the device body 1 at a location parallel to the swinging surface of the operating lever 3.

A conductive contact piece 16 for forming a switch circuit is formed on the front surface of the switch plate 15.

At a portion of the switch plate 15 facing the conductive contact piece 16, a current collector arm 1 made of an electrically insulating material is fixedly supported by the support shaft 2.
7 is arranged, and this current collecting arm 17 has the conductive contact piece 16
A current collecting contact piece 18 is provided for making contact with the switch circuit.

A conductive wire 19 is connected to the conductive contact piece 16 of the switch board 15, and the conductive wire 19 is pulled out from an opening 20 on the side of the box 1b, and is connected to a power supply battery and a flashlight mounted on the front and rear of the bicycle. Lamp (not shown)
It is now possible to connect to.

The bicycle flash lamp switch device configured as described above is used in combination with a power supply battery and a flash lamp.
(not shown), a flash lamp attached to the handlebar of the bicycle and attached to both sides of the rear of the bicycle body, and a battery in a power supply box supported at an appropriate part of the bicycle body are connected to the switch board inside the housing 1. If connected to the conductive wire 19 of No. 15, it will be configured as a direction indicator.

Therefore, when changing the course of the bicycle, the lever 3 is swung from the neutral position against the spring 9 in that direction, and the suction cup 6 in that swiveling direction is pressed against the receiving plate 10 for suction. When the lever 3 is moved, the lever 3 is held in its swinging position by the suction action.

At the same time, the current collector arm 17 linked to the lever 3 via the support shaft 2 is also swung in the same direction from its neutral position, so that this oscillation causes the current collecting arm 17 to connect with the conductive contact piece 16 of the switch plate 15. In the switch circuit formed by the contact piece 18, one flash lamp circuit is closed, and the lamp flashes.

The blinking operation of the flash lamp is performed when the lever 3 is moved to the suction cup 6.
The suction negative pressure chamber 14 of the suction cup 6 adsorbed to the receiving plate 10 narrows the air passage by the pores 11 of the receiving plate 10 and the screws 13. After adsorption, air gradually enters the suction negative pressure chamber 14 of the suction cup from the narrowed air passage, so that the negative pressure in the negative pressure chamber 14 becomes smaller than the suction force by the suction cup 6. At this time, the suction cup 6 is separated from the receiving plate 10 and returned to the neutral position by the action of the spring 9, and at the same time, the current collecting arm 17 is also returned to the neutral position, at which point the blinking operation of the lamp is stopped.

Therefore, according to the configuration of the switch device described above, if the lever of the switch is swung in a certain direction, even if you take your hand off the lever and return it to the handle, the lever will be held at that swiveling position, Since the bicycle is automatically returned to the neutral position after a time delay, it is extremely effective in preventing the risk of unstable bicycle handle operation due to switch lever operation.

In addition, the flashing operation time of the flash lamp is determined by the resistance of the narrowed air passage created by the cylinder shaft 12 and the screw plug 13.
It has the advantage of being able to be changed arbitrarily by adjusting the insertion length of the screw plug.

In addition, the blinking means of the flash lamp can be selected from a bimetal type lamp or an electronic circuit means using a transistor, and especially in the latter case, the circuit components must be incorporated into the body. Can be done.

As described above, according to this invention, a swingable switch lever that is held in a neutral position by the action of a spring is supported on the device body, and the switch lever has a switch lever on both sides of the swinging direction. A suction cup is fixed to each side of the switch lever, and a receiving plate is provided on each side of the switch lever to which the suction cup on the lever side can be attracted when the lever is swung. A hole communicating with the suction negative pressure chamber of the suction cup is opened, and the hole is connected to the outside through an adjustable narrow passage provided on the opposite side of the plate. It has a built-in switch mechanism that opens and closes the flash lamp circuit in conjunction with the motor operation, so it can be used in a bicycle flash lamp switch device to fully demonstrate its function and practical utility. Ru.

In other words, in terms of functionality, if you swing the control lever in a predetermined direction, the lamp will continue to flash for a certain period of time even if you release the lever, which will stabilize the bicycle's steering operation. The blinking operation time of the flash lamp can also be adjusted arbitrarily.

Furthermore, in terms of practicality, the structure is simple and can be manufactured at low cost, so it can greatly contribute to the spread of bicycle flash lamps.
