Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a remote-controlled toy in which starting and stopping of a toy actuating section operated by a mechanical power means such as a mainspring or a flywheel is controlled by an electric signal in a receiver. The present invention relates to a drive device for use in a vehicle.

Conventionally, in toy drive devices operated by remote control, motors have been used as power means. Therefore, a battery for driving the motor must be prepared, which inevitably increases the size of the toy, making it difficult to downsize a toy that operates by remote control. In addition, conventional toys operated by remote control have relatively advanced control functions, making their structures complex, requiring operating skills, and requiring children of a certain age to operate them. There was a drawback that I said I couldn't do it. On the other hand, recent advances in processing technology have led to longer driving times in mechanical power means such as springs and miniaturization of mechanical power means.

In view of the above circumstances, the present invention operates the actuating part of the toy by a mechanical power means that can be driven for a long time, and also allows the actuating part to be controlled by a simple remote control device. The purpose of the present invention is to provide a toy drive device that is small and easy to operate.

Therefore, the present invention forms a power section using mechanical power means such as a mainspring or a flywheel, connects this power section and the operating section of the toy through a drive transmission mechanism, and provides electrical control from a receiver. A control body operated by a signal is incorporated into the drive transmission mechanism.

An example in which the present invention is used as a drive device for a pull-back traveling toy will be described below.

1 is a side view of an embodiment of the present invention, FIG. 2 is a cross-sectional plan view of the main part of FIG. 1, and FIG. 3 is a vertical cross-sectional view of the main part of FIG. 1. In these drawings, reference numeral 1 denotes a splittable case body, inside which is a power section 2 consisting of a mainspring, and a hoisting transmission mechanism 3 consisting of a group of gears.
A drive transmission mechanism 4 is provided. Reference numeral 5 denotes a drive shaft, and drive wheels, which are actuating parts 6 of the toy, are attached to both ends of the shaft, and are connected to the power part 2 via both transmission mechanisms 3 and 4 in parallel. Therefore, when the running toy is pulled back, driving force is stored in the power unit 2, and when the hand is released, the running toy runs. The rotation ratio of the drive transmission mechanism 4 is such that the operating portion 6 rotates 14 times when the mainspring shaft 2a rotates once.

Reference numeral 7 denotes a governor connected to the drive transmission mechanism 4 via a gear 8, which keeps the rotational speed of the operating section 6 constant. Reference numeral 9 denotes a coil disposed in a space within the case body 1, facing the governor 7. 10 is governor 7
This is a stopper provided between the coil 9 and the coil 9, and is formed to be swingable via a leaf spring 11. The rotation of the governor 7 is stopped by pressing against one side of the stopper 10. The governor 7, coil 9, stopper 10, etc. form a control body.

Reference numeral 12 denotes a printed circuit board fixed to the side surface of the case body 1, on which the coil 9 protruding into the case body 1 and a normally closed switch 14 are provided at the lower part, and the receiver 13 is formed at the upper part. Electronic components are mounted above the case body 1. Reference numeral 15 denotes a separating member of the switch 14 fixed to the mainspring shaft 2a. 4 and 5 are examples of circuit diagrams of the receiver 13 that receives a signal from a transmitter (not shown) and outputs an electrical control signal to the control body, and in both cases, only an impulse signal is received. It operates with. Among these, the electric circuit shown in Figure 4 using SCR is used when the power supply voltage is 1.5V or more, and the electric circuit shown in Figure 5 using ordinary transistors is used when the power supply voltage is 1.5V or less. Use in the case of

Note that in an electric circuit using transistors, a capacitor C and a resistor R in the circuit function as a timer. As a result, the current flowing through the coil 9 is automatically cut off after a certain period of time, and the stopper 10 stops the rotation of the governor 7 in the same manner as described above. Therefore, the normally closed switch 14 is not required in this case.

The signal between the transmitter (not shown) and the receiver 13 may be radio waves, light waves, or sound waves;
No matter what kind of signal is used, it is sufficient that the transmitter can transmit an impulse signal. Therefore, for example, it is possible to create a small, simple, and extremely easy-to-operate transmitter that uses a piezoelectric element or the like, and a receiver that includes a simple circuit.

The toy drive device of this embodiment having such a configuration is operated as follows.

The running toy is pressed against the running surface and pulled back,
Driving force is stored in the mainspring power section 2 via the winding transmission mechanism 3. Next, when the user takes his hand off the running toy and places it on the running surface, the drive transmission mechanism 4 attempts to rotate due to the driving force from the power unit 2. However, at this time, since no current is flowing through the coil 9, the stopper 10 is pressed against the side surface of the governor 7 by the elastic force of the leaf spring 11, and the drive transmission mechanism 4 is rotated via the governor 7. The running toy is stopped. In this state, when a signal is given to the receiver 13 from the transmitter, the circuit of the receiver 13 is activated and current flows through the coil 9. As a result, the coil 9 attracts the stopper 10 against the elastic force of the leaf spring 11, releases the pressure contact of the side surface of the governor 7 by the stopper 10, and enables the drive transmission mechanism 4 to rotate at a constant speed. When the drive transmission mechanism 4 becomes rotatable, the driving force of the power section 2 rotates the drive wheels of the operating section 6 at a constant speed, causing the traveling toy to start and travel.

When the traveling toy continues to run at a constant speed and the drive wheel of the actuating section 6 rotates 14 times, the mainspring shaft 2a of the power section also rotates once, causing the separating member 15 to open the normally closed switch 14 and stop the current flowing through the coil 9. Cut off. By cutting off the coil current, the stopper 10 presses against the side surface of the governor 7 again to stop the running toy. When a signal is transmitted from the transmitter, the traveling toy starts transmitting and traveling again as described above. Therefore, it is possible to start and stop the running toy by remote control.

In addition to the above embodiments, the present invention includes the following aspects.

That is, any type of toy may be used as long as it has an operating part, and it can also be used as a robot toy or a house toy. The power section is not limited to a mainspring, but may be a flywheel or the like as long as it is a mechanical power means, and the driving force accumulating means is not limited to any type. Further, means such as a belt, a cam, a link, etc. can be selected as the drive transmission mechanism depending on the type of toy.

Regarding the operating mode of the toy operating section, it is possible to stop the operating section that is constantly operating by operating the transmitter, or it is possible to start the operation by removing the switch release member, etc. Then power section 2
The structure may be such that the power continues until the driving force stored in the motor is exhausted.

It should be noted that a device with a simplified transmitter and receiver is particularly suitable for use in a toy that can be played by remote control indoors or on a desk.

As described above, according to the present invention, the actuating part of the toy is actuated by mechanical power means such as a spring, and the actuating part is configured to be controlled by a simple remote control device. Therefore, it is possible to obtain a toy drive device that is small and simple in structure, and in turn, it is possible to obtain a very small and remotely controllable toy. In addition, it is easy to operate and has the advantage that even young children can easily operate it.
