Description

DETAILED DESCRIPTION OF THE INVENTION The present invention makes it possible to simultaneously turn on headlights, taillights, warning lights, etc. for a traveling toy.

Generally, the biggest drawback of toys that run on batteries is battery consumption, and it is out of the question to turn on the headlights, taillights, and warning lights at the same time, and the batteries will run out quickly. It is natural that such reckless toys are not actually sold. The present invention enables multiple light bulbs to be lit at the same time by turning them on only when the flywheel-driven vehicle is running.

Furthermore, by increasing the supply voltage to an overvoltage, which may seem like a reckless measure, it is possible to create a novel toy that has high brightness that can overcome indoor light and can simultaneously light up a large number of light bulbs. An example will be described below.

In FIG. 1, a traveling vehicle 11 has a headlight 12, a taillight 18,
Each vehicle is equipped with two warning lights 14, which are turned on only when driving by a built-in battery and a switch (not shown) to be described later. A light bulb with a rated voltage setting is used for connecting two batteries in series; the one commonly sold is a 2°5V bulb. Even though the nominal voltage of batteries is 1.5V, when the light is turned on, the voltage drops due to internal resistance, etc., and when two AA batteries are connected in series, the voltage drops by 0.3V.
When three bulbs A are lit, the voltage across the bulbs will be 2.5V.

If the voltage is rated, two batteries should be connected in series.

In the example, three batteries were connected in series. This is an abnormal method and results in an overvoltage of 1.5 times. However, when there are six light bulbs, the voltage drops compared to when there are three light bulbs, and it becomes darker when using AA batteries.

So, I used AA batteries and when I experimented with 3 AA batteries in series, I found an overvoltage of L5 V (1.4 times the rated voltage of 2.5V). (A in Appendix 1) According to literature on light bulbs, if the voltage is increased to 1.4 times the rated voltage, the brightness will triple. It may seem strange that 1.4 times the voltage would give three times the brightness, but it is a characteristic of incandescent light bulbs that when overvoltage is applied, the hue shifts from long wavelengths to short wavelengths, saving energy that would otherwise be wasted by invisible infrared light. it is conceivable that.

The significant increase in brightness in this case is tentatively called the wavelength effect. However, the lifespan of a light bulb is -100- times shorter.

For example, if the life is 1000 hours at the rated voltage, the life will be 10 hours at 1.4 times the overpressure. If the running time for - times is 5 seconds, this corresponds to 7200 times of play. This is not an unbearably short life. Rather, the high brightness that can be obtained in exchange for the short lifespan of a light bulb is more attractive, and the triple-brightness shines brighter than indoor light, entertaining not only children but also adults.

In order to obtain highly luminous light, common sense suggests that, for example, 8
It is also possible to increase the battery capacity by eight times by using a light bulb with twice the amperage. However, it is difficult to increase the capacity of batteries, and batteries become little more than toys. Therefore, even if we rely on the common sense method of paralleling many large light bulbs, the present invention uses an abnormally small capacity battery that does not compensate for the rated current of the light bulb, and instead inserts an extra battery in series. It is also possible to use means of obtaining a rated voltage. For example, if you connect 8 AA batteries in series, 2.
When 122 5V 0.8A bulbs were used, the voltage across the bulb was 2.5V. This is the rated voltage of the light bulb, but the battery voltage is 1.5 times higher, and the amount of light is twice that of case A. (C in Appendix 1) The present invention is characterized by the seemingly reckless supply of overvoltage by using three batteries instead of two, and if six light bulbs of 2.5 V OJ A are connected in parallel. Due to the aforementioned wavelength effect, the light bulb shines 8 times brighter, and the light bulb becomes 2.5 V O.
If there were 122 3A bulbs, the amount of light would be double. C is slightly inferior to A. You are free to adopt either method. The former has good battery efficiency, while the latter does not shorten the life of the bulb. Each has its own characteristics, so it is best to use them appropriately, and you can also use both. (B of Appendix 1
) Attached Table 1 All of the experimental examples where the voltage at both ends of the light bulb is higher than the voltage at both ends of the light bulb used a 2.5V bulb and a AA battery, but of course the embodiments use light bulbs with various other voltages, and use other types of batteries or other batteries. A number of them may be connected in series, and the voltage can be adjusted freely by inserting a resistor.

Consider one of the three types of headlights, tail lights, and warning lights, or omit the three types and instead consider one or two types of optional lights such as rooftop lights, decorative lights, fog lights, direction indicators, interior lights, etc. More than one seed may be added.

In FIG. 2, reference numeral 20 indicates a normally open microswitch, and a weight 4 is attached to the tip of the lever 15.

The switch 20 is fixedly attached to the rotating shaft l, and
and is electrically connected to the insulated ring 10. axis 1
Due to the rotation of , the weight 4 moves to the 4' position, the switch closes, and the shaft 1 and ring 10. Electricity is applied to the light bulb via the brush 7. Therefore, the light is turned on only while the shaft 1 is rotating. It is convenient to make the rotating shaft coaxial with the flywheel, but it does not need to be coaxial as long as transmission is possible. Further, the flywheel and the switch section may be integrated.

Although the structure of the switch portion is not limited in any way, it is illustrated in FIGS. 3 to 18 for reference.

In common to each figure, 1 is a rotating shaft, 2 is a support, 3 is a spring, 4 is a centrifugal movable piece, 5 is a conductor piece, 6 is a contact, 8 is an insulating layer, W is a weight, and 20 is a micro switch. . The length of the shaft 1 may be such that it terminates at the switch part (the part indicated by the solid line in the figure), or it may extend through the switch part (the part indicated by the dotted line 1' in the figure).

Descriptions of well-known methods for connecting the switch portion to a power source, such as conductive wires, brushes, rings, etc., have been omitted.

The springs are too thin to be drawn, so their thickness is omitted and shown as a single solid line.
