Abstract

PURPOSE:To enable indicating a standstill pattern during the revolution of wheels by providing a light between a tire wheel and a wheel cap having a pattern-shaped transparent part, and by lighting this light intermittently by a strobe circuit simultaneously with the revolution of the wheel. CONSTITUTION:When driving is started in the state where a main switch 9 is turned on before an automobile departs and the driving speed of the vehicle reaches a prescribed speed, an auxiliary switch 10 of centrifugal closed circuit type is turned on, and the operations of a strobe circuit S and an electromagnetic sensor MS are started. The electromagnetic sensor MS consists of a sensitive coil 11 and a permanent magnet 12 and generates a wheel revolution signal directly proportional to the revolutional speed of the wheel, and the strobe circuit S momentarily gives a high voltage electric current to a trigger coil simultaneously with the revolution signal. By this, a light 5 provided between a tire wheel 2 and a wheel cap 3 on which a pattern-shaped transparent part 4 is formed is lighted intermittently and a standstill pattern appears.

Description

Detailed Description of the Invention A1 Object of the Invention (Field of Industrial Application) The present invention relates to an illumination device for wheels and tires while a car is running, and more specifically, an illumination device located on the inner surface of a hubcap attached to the tire wheel surface. An object of the present invention is to provide a tire wheel illumination device in which a pattern on a transparent part of a hubcap can be clearly observed from the outside without rotating by providing a strobe illumination light that emits light intermittently in synchronization with the running rotation of the wheel. That is.

[Conventional technology]

In response to the desire for individualization of automobiles, it is common practice to make the shape, color, pattern, etc. of the vehicle body and accessories unique.

Wheel caps with a unique design pattern are used.

(Problem to be Solved by the Invention) The design pattern of the wheel hubcap of an automobile is visible from the outside when the vehicle is stopped, but when the vehicle is running and rotating, it is only visible as a slightly concentric circle pattern, and the design is sufficient. No effect is obtained, and vA cannot be detected at all, especially at night.

In order to solve the above-mentioned problems, the present inventor invented an automobile wheel illumination device in which a strobe illumination lamp that emits light intermittently in synchronization with the rotation of the wheel is provided on the fender at the wheel position of the automobile.
It was previously submitted as Japanese Patent Application No. 1982-192554.

However, since the above method projects light from diagonally outside the tire wheel, the illuminance on the tire wheel surface is uneven.
There is a drawback that the design of the tire wheel and hubcap surface cannot be clearly seen at night, but during the day, and in the case of steered wheels, the relative position with the strobe light changes, making it impossible to illuminate. Sometimes it happened.

1. Structure of the Invention [Means for Solving the Problems] The present invention provides a hub cap having a patterned light-transmitting portion attached to a tire wheel of an automobile wheel, and on the inner surface side thereof, an intermittent light is provided in synchronization with the rotation of the center wheel. The above-mentioned conventional problems are solved by providing a strobe lighting lamp that emits light.

That is, the present invention provides an illumination lamp provided between a tire wheel of a wheel and a hubcap having a patterned transparent part attached to the side surface thereof, and an illumination lamp provided oppositely between the tire wheel surface and the axle support part. The strobe circuit comprises a strobe circuit that causes the illumination light to emit light intermittently in synchronization with wheel rotation by a trigger circuit operated via a non-contact sensor, and the strobe circuit and its power source are installed either on the tire wheel side or on the vehicle body side. The subject matter is a tire wheel illumination device for an automobile wheel, characterized in that the power supply circuit of the strobe circuit is controlled by a switch provided in the tire wheel that closes in response to the centrifugal force of the running rotation of the wheel. This is an embodiment of the present invention.

In the above, the wheel cap is made of a metal plate or a plastic plate that covers the entire side surface of the tire wheel or its central area, and the cap surface has an arbitrary pattern-shaped opening in the shape of a letter 1, etc. , model I! A light-transmitting portion made of a transparent portion is formed.

The illumination light is a discharge lamp such as a xenon lamp that emits light when triggered by a trigger voltage,9 or a light emitting diode.2 The illumination light is usually removably attached to the axle support end of the tire wheel, but it is installed at the center of the inner surface of the hubcap. Good too.

The non-contact sensor consists of a permanent magnet and a sensing coil.
Either a 131& type or a photoelectric type consisting of a light projecting part and a light receiving part is used, one element of which is installed on the side surface of the tire wheel, and the other corresponding element is installed opposite to the axle support part.

The strobe circuit uses a tire wheel as its power source.
It is connected to an independent power source consisting of 6 dry batteries mounted on a wheel or an existing power source such as a storage battery in a car, and has a trigger circuit that operates the lighting lamp to emit light intermittently based on the wheel rotation signal of the sensor. A conventionally known strobe circuit that stores electricity, discharges sensor signals, etc. is used. The strobe circuit is arranged on either the vehicle body side or the tire wheel side.

Naturally, a main switch is installed in the fiff1 circuit to the strobe circuit, but in order to activate the circuit only when the desired driving condition is achieved, a sub-switch is installed on the tire wheel side that closes in response to the rotating centrifugal force. It is desirable to provide a power source to suppress consumption of the power source battery.

If each of the above circuits spans the wheel side and the axle support side,
Connection is made by a sliding contact consisting of an appropriate number of rung-shaped terminals on the inner surface of the tire wheel and a sliding contact terminal on the axle support side.

Note that when a dry battery power source, a strobe circuit device, etc. are provided on the tire wheel side, it is necessary to arrange them so as to maintain rotational balance.

[Function] The VA@ of the present invention has the above-described configuration, so that if the main switch is closed before or while the vehicle is running, the strobe circuit is activated in response to a trigger signal from the non-contact sensor every time the wheel rotates, and the illumination light is activated. lights up intermittently, and the illumination light is emitted to the outside from the patterned transparent part of the hubcap, and the highly bright transparent part pattern moves in the direction of travel as a clear pattern that does not rotate from the outside during a constant rotational phase of the wheel. It can be visually recognized as such.

33. If the wheel cap is attached only to the center of the tire wheel, some of the light from the patterned light-transmitting part of the cap is applied to the periphery of the tire wheel, so that the wheel cap is transparent. It is also possible to observe the light pattern and the pattern on the peripheral surface of the tire wheel.
