Description

[Detailed description of the invention] This invention is an automatic switch for wheeled vehicles that automatically turns on when a toy car, train, children's car, bicycle, etc. starts moving forward, and turns off automatically when it stops. It is related to.

Traditionally, toy cars, trains, etc., were not suitable for small children because when they were manually turned on, sirens, buzzers, running sounds sounded, and lights turned on or flashed. Even when the system is stopped, it is easy to forget to turn it off, and the battery is wasted.

In this invention, when the wheel axle starts rotating, the driven wheel is displaced by rotational torque and the switch is turned on, and when the wheel axle stops, the driven wheel is displaced by its own weight and the switch is turned off. It automatically sounds a siren, buzzer, and running sound, and lights or flashes lights so that young children can move toy cars, trains, etc. with interest.
This allows children to drive cars and bicycles.

Next, an embodiment of the present invention shown in the accompanying drawings will be described in detail. A drive gear 4 is fixed between the wheel axles 3 of the wheels 1 and 2. A driven gear 5 meshes with the driving gear 4, and a shaft 7 of the driven gear 5 is attached to the tip of a lever 6 pivotally connected to the wheel shaft 3.
It is pivoted. The driven gear 5 is adapted to be stopped by its own weight to a stopper 8 located at a lower position. Reference numeral 9 denotes a switch that is turned on by the upward displacement of the driven gear 5, and operates 10 such as a siren, a buzzer, a running sound, and a light. 11 is a battery.

Next, the effect will be explained. When the vehicle body is stopped, the driven gear 6 is displaced by its own weight to a downward position as shown in FIG.
is turned off. Next, when the vehicle body is moved forward and the wheel shaft 3 begins to rotate in the forward direction A, the driving torque causes the driving gear 4 to also rotate, as shown in FIG.
are rotated together in the direction B and displaced to the upper position, and the driven gear 5 presses the switch 8 to turn on. While the vehicle is traveling and the wheel axle 3 is rotating, the driven gear 5 rotates in conjunction with the rotation of the drive gear 4 and is maintained in that state by the rotational torque, and the switch 8 continues to be turned on, causing the siren, buzzer, and driving gear to rotate. Make onomatopoeic sounds or turn on or flash lights.

When the vehicle stops running, the switch 9 is automatically turned off as shown in FIG.

According to this invention, the switch can be turned on automatically by rotating the wheel axle only when the vehicle is moving, and automatically turned off when the vehicle is stopped, so when used as a toy, young children will be interested in the toy car. ,
It can be used to move trains, children's cars, and bicycles, and even when used for purposes other than toys, it can be widely used as a switch for turning on only when the rotating shaft of a vehicle body or the like rotates.

Note that a friction rotation shaft may be used instead of the driving gear and the driven gear, and any type of switch such as a photoelectric type or an electromagnetic type may be used.
