Description

[Detailed Description of the Invention] The present invention is a device that saves battery power when a large number of light bulbs such as headlights, taillights, warning lights, etc. of a toy vehicle are turned on at the same time.

Generally, young children have little interest in conserving batteries, and if a total of six lights (two headlights, two taillights, and two warning lights) are turned on at the same time, the battery will run out quickly. The present invention relates to an automatic switch that turns on only when the flywheel is rotating and turns off when the flywheel stops, greatly extending battery life.

In FIG. 1, when a weight 4 that is supported laterally via an elastic body 3 is provided to a rotating body 2 provided on a flywheel shaft 1, the weight is rotated by centrifugal force due to rotation. 2 Move to the position shown in Figure 4'. The conductor plate 5 moves with the weight while being supported by the weight 4, and the tip 6 moves to 6'. Reference numeral 6' is located in the extending direction of the shaft and contacts the contact 7, which is also located in the extending direction, to conduct electricity.

Since the flywheel is a high-speed rotating body, axis 1
It is necessary to consider reducing the air resistance of rotating parts installed in the rotor 2, and therefore, it is desirable that the rotating body 2 is shaped like a saucer or a disk. Furthermore, in order to maintain balance, it is necessary to symmetrically provide a heavy object W sufficient to balance the total weight of the weight, the elastic body, and the conductor plate. The end portion S of the disk serves as a support from which the weight will not fly out, and limits the movement distance of the weight 4. Moreover, it is preferable that the conductive plate 5 be in contact with the contact point in a state perpendicular to the rotation axis.

In implementing the present invention, the conductor 5 may be rod-shaped instead of plate-shaped, and the contact 7 may be saucer-shaped. The contact point 7 is preferably located on an extension of the shaft so that friction is low. However, if you are prepared for a lot of friction, you can make contact other than by extending the shaft. The extension direction of the axis stated in the claims for utility model registration has a vague meaning;
For example, words like "right" and "left" merely indicate direction, similar to "up" and "down".

It would be interesting to keep the light on for a few seconds even after the flywheel stops. In order to meet such demands, it is best to separate the flywheel from the axis of the flywheel instead of connecting it directly, and use a one-way type transmission such as a combination of a ratchet and pawl, in which the flywheel converts rotational energy into running force. Even after the lamp is used up and stopped, the switch part continues to rotate for a few seconds and the light can be turned on.

FIGS. 3 and 4 show an example of a case in which a weight is supported obliquely, and FIG. 5 shows an example of a saucer-type contact.

The effect of the present invention is that by turning on the light only while the flywheel is rotating, it is possible to avoid consumption due to children forgetting to turn it off, and the battery life can be significantly extended.

Claims (1)

[Scope of utility model registration request] In a running toy equipped with a battery and a light bulb, a weight 4 supported laterally via an elastic body 3 with respect to a rotating body 2 provided on a flywheel shaft 1 is displaced by centrifugal force. A running toy equipped with an automatic lighting switch in which a tip 6 of a conductor 5 supported by a conductor 5 moves in the direction of extension of a shaft 1 and contacts a contact point 7 provided in the direction of extension of the shaft to energize.
