[Industrial applications]

 The present invention relates to a bicycle pedal with a blinking light.

[0002]

[Prior art and its problems]

 In general, bicycle pedals are provided with synthetic resin plate-shaped reflective lenses (also called reflectors) attached to the front and rear surfaces orthogonal to the foot surface on which the foot rests, so that the bicycle can be simply decorated. Instead, the lights of cars approaching from behind at night are intermittently reflected so that the driver of the car can recognize the bicycle ahead and prevent accidents. For example, JP-B-57-24273, JP-B-55-20907, JP-A-50-48641, JP-B-52-1252, JP-B-49-31639, and JP-B-43-22583. See the official gazette.

However, in the conventional bicycle pedal with a reflective lens, the reflective lens is liable to get dirty, and the reflective function of the light of the automobile is lost as well as the decorative value. An analysis of the causes of such inconvenience has led to the current tendency for bicycles to be handled by neglecting habits such as cleaning dirt and lubricating oil, and leaving them unused. It is thought that this is the main reason.

Therefore, in order to eliminate such an unfavorable climate (problem), after pondering and searching, the more the decorative function is increased, the more interesting the bicycle operator is, and as a result, the car body is also cared for. However, I came to the conclusion that night riding will be safe.

[Means for Solving the Problems]

 That is, the gist of the present invention is that a pedal shaft is provided laterally on a flat box-shaped pedal body through ball bearings, and a screw portion for connecting with a gear crank is provided at the outer end of the pedal shaft on the vehicle body side. In a bicycle pedal in which a plate-shaped reflective lens made of synthetic resin is detachably attached to the front and rear surfaces of the pedal body, a miniature bulb is built into the pedal body behind the reflective lens and A bicycle pedal in which a light flashes, characterized in that a light bulb is axially slidable on the pedal shaft and is connected to a power source through a cam switch equipped with a disc cam that integrally rotates. It is in.

【Example】

 The structure of the present invention, together with its operation, will be described in detail with reference to the embodiments shown in the accompanying drawings. FIG. 1 is an exploded perspective view of an embodiment of the present invention.

In the drawing, reference numeral 1 denotes a flat box bicycle pedal body (also referred to as a step) made of a light metal, for example, an aluminum alloy, and a pedal shaft 2 is projectingly provided on a bicycle body (not shown) side thereof. The pedal shaft 2 is rotatably passed through the pedal body 1 via a ball bearing (not shown). The pedal shaft 2 is composed of a small-diameter portion (not shown) built in the pedal body 1 and a large-diameter base portion 2a protruding from the pedal body 1. A screw portion is provided outside the large-diameter base portion 2a. 2b is formed. The screw portion 2b is screwed onto a gear crank (not shown) of the bicycle body. The large-diameter base portion 2a is provided with a pair of surface ridges 3 for hanging a spanner. In the figure, reference numeral 4 denotes a cap for covering one of the ball bearings of the pedal shaft 2, and the foot surface 5 above and below the pedal body 1 is provided with anti-slip unevenness.

The above structure is a normal bicycle pedal, and the present invention has the following structure.

That is, in the pedal main body 1, a plate-shaped reflective lens 7 made of synthetic resin is attached to the front and rear surfaces (which means the front and rear in the traveling direction of the bicycle) 6 which are orthogonal to the step surface 5 and are attached to each other. It is attached so that it can be freely inserted and removed through the connector 9. A miniature electric bulb 8 is detachably provided in the pedal body 1 on the back side of the reflection lens 7, and light emitted by the miniature electric bulb 8 is emitted through the reflection lens 6 in the front-rear direction of the bicycle. ing. Therefore, the miniature electric bulb 8 is built in the pedal body 1 in a pair of front and rear.

A pair of cam switch bodies 11 are provided on an inner surface 10 of the pedal body 1 which is orthogonal to the step surface 5 and is on the vehicle body side. The cam switch body 11 is provided with a lever-shaped contactor 12 made of an elastic body on the pedal shaft 2 side. On the other hand, the pedal shaft 2 is fitted with a disc cam 13 having a notch surface 13a so as to slidably transmit the rotation to the large-diameter base portion 2a in the axial direction. The contactor 12 is opened and closed by means of. That is, the large-diameter base portion 2a is provided with the surface trib 3 as described above, but the fitting hole 13b of the disc cam 13 is joined to the surface trig 3 to transmit the rotation. There is. The disc cam 13 is slidable in the axial space of the large-diameter base portion 2a, and if the disc cam 13 is moved to the gear crank side, the disc cam 13 and the contact 13 will move. If the relationship is broken and the pedal body 1 is moved to the contact side, the contact with the contact 13 becomes possible, and the switch functions. Therefore, it is sufficient to move the disc cam 13 to the pedal body 1 side only when riding at night.

The cam switch body 11 is covered with a box-shaped cover 14. In addition, the flat box-shaped pedal body 1 has a built-in battery (not shown) for the power source of the miniature electric bulb 8 in its space. Connected with.

Next, the operation of this embodiment will be described. When riding at night, the disc cam 13 is slid toward the pedal body 1 so as to come into contact with the contactor 13. Therefore, when the pedal body 1 is stepped on, the pedal body 1 revolves around and the front and rear surfaces 6 of the pedal body 1 are seen and hidden from behind, so that the reflective lens 7 intermittently reflects the light of the bicycle on the rear side and the pedal shaft. 2, the cam switch body 11 rotates about its own axis, and the disc cam 13 of the pedal shaft 2 causes the miniature bulb 8 to blink. As a result, the reflected light and the flash light of the miniature light bulb 8 are overlapped and illuminate the rear side, which is extremely beautiful and gives a strong attention to the rear vehicle driver.

Although the cam switch of this embodiment is provided outside the pedal body 1, the present invention is not limited to this, and may be provided inside the pedal body 1.

[Effect of device]

 According to the present invention, since the miniature light bulb that blinks and emits a flash light is built into the bicycle pedal together with the reflecting lens, not only the bicycle pedal can be further decorated, but also night riding can be made safer. Moreover, since it emits a flash of light through the reflective lens, it is extremely beautiful and the reflective lens also serves as a cover for miniature bulbs.

Moreover, since the disk cam is provided on the existing pedal shaft, the dead space can be used and there is no need to make a special design change.
