Description

[Detailed description of the invention] This invention is a toy racing car that receives power from a conductive rail and runs on a rail board, and allows the running speeds of two vehicles running in tandem to be changed arbitrarily. Embodiments of the present invention will be described below with reference to the drawings.
Two sets of conductive rails 2, 3.4 and 2', 3' and 4' are arranged in parallel on the top, and the AC current is used as the power source 5, and the two basic wirings 6.7 of the AC current are divided respectively. Diodes 12, 13, 14 and 1 are connected to each of the four wires 8, 9, 10 and 11 for half-wave rectification, respectively.
5, and forward/reverse switches 26 and 27 are provided in each set of the two sets of wiring, and the first of the two sets of three conductive rails 2 and 2', 3 and 3', and 4 and 4' Connect both the wires 8 and 9 obtained by dividing one of the two base wires 6 and 7 to the conductive rails 2 and 2', and connect the two sets of conductive rails 2 and 2' and 3 and 3' to the three wires. , 4 and 4', wirings 10 and 11, which are obtained by dividing the other 7 of the base wirings 6 and 7, are separately connected to the remaining second conductive rails 3 and 3' and third conductive rails 4 and 4', respectively. Variable resistors 16 and 17 are provided respectively in the two circuits through which the direct current flows, and conductive rails 2 to 4 are provided with variable resistors 16 and 17, respectively.
The current collecting brushes 19 and 20 of the first vehicle 18, which travels by collecting current from 2' to 4', are brought into contact with the first conductive rail 2 or 2' and the second conductive rail 3 or 3'. Current collector brushes 22 and 2 of a second vehicle 21 different from the first vehicle 18
3 is a first conductive rail 2 or 2' and a third conductive rail 4
Alternatively, the present invention can be implemented by making contact with 4' to constitute a power supply device for a racing toy.

Note that the front wheels of the vehicle 18, 21 running on the track base 1 face in the direction of the track guide 28 or 29, and a part of the vehicle 18 or 21 comes into contact with the track guide 28 or 29 and runs according to the track guide. In this way, the drive wheels of the vehicle 18 or 21 always rotate in the forward direction regardless of whether the motor 24 or 25 rotates in the forward direction or in the reverse direction.
．． By using the power supply device of the present invention in a racing car toy with a configuration in which the direction of the front wheels changes by forward/reverse rotation of 25, the positive/negative side of the current flowing through the conductive rail can be changed by switching the forward/reverse switch 26 or 27. Change the running route and move the conductive rail 2 according to the running route guide 28.
The vehicle, which was running while receiving power from the conductive rails 2 to 4, is moved to run along the track guide 29, and
The vehicle can be driven by receiving power from ' to 4 ', and the vehicle that was traveling along the road guide 29 can be moved to the road guide 28 side to continue moving forward.

The present invention is as described above, and when two sets of three conductive rails are used to run a royal vehicle, the first vehicle receives power from the first conductive rail and the second conductive rail, The second vehicle receives power from the first conductive rail and the third conductive rail, and changes the speed of the first vehicle and the fourth vehicle by operating respective variable resistors provided in these circuits. It is very interesting because each gear can be changed individually.

In particular, in this invention, the two basic wirings for alternating current are each divided into two sets of four wirings, each of which is provided with a forward/reverse switch, and all of the four wirings are equipped with a forward/reverse switch. Since a diode for half-wave rectification is provided, compared to other similar proposals, for example, - pair of conductive rails 2,
3.4 Even when the royal vehicle 18.21 is run on top of it, the current used by the royal vehicle 18.21 after half-wave rectification is different, so the two cars may be affected by each other when running. There is no.

In addition, in the present invention, by using the forward/reverse switch as described above, it is possible to run a large vehicle without being affected by the running speed, etc. by using the positive and negative sides after half-wave rectification, respectively. , since four diodes are used, it is possible to prevent the occurrence of current short circuits, and the transformer can also be made smaller and provided at a lower cost.
