Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a running toy that is operated by a mechanical power means such as a spring or a flywheel and is started and stopped by remote control from a transmitting device.

Traveling toys are one of the most popular types of traveling toys, and many types have been put into practical use to date. In particular, so-called remote-controlled running toys, which can be remotely controlled to start and stop, change direction, go forward or backward, change speed, etc., are widely popular because they allow a variety of play activities.

However, since conventional remote-controlled running toys use motors as a power means,
Since a motor and a battery for driving the motor had to be provided, the running toy inevitably became larger, and it was impossible to create a smaller one. Further, the transmitting device and the receiving device have become complicated, large and expensive, and require skill to operate, making them difficult for younger children to play with.

On the other hand, advances in processing technology in recent years have made it possible to drive mechanical power means such as springs for longer periods of time and downsize them.

In view of the above circumstances, the present invention forms a power section using a mechanical power means that can be driven for a long time, and also provides a simple braking system that starts and stops the power section in response to a signal from a receiving device. The purpose of the present invention is to provide a small remote-controlled running toy that can be operated using a device. Another object of the present invention is to provide a traveling toy that is easy to operate using a simple transmitter and receiver, has a simple and sturdy structure, and can be easily played on a desk or indoors.

Hereinafter, an embodiment of the pullback type traveling toy shown in the drawings will be described.

FIG. 1 is an explanatory diagram of an embodiment, and FIG. 2 is a sectional plan view of a main part of FIG. 1. In these drawings, 1 is the chassis of the traveling body, and 2 is the body of the traveling body. Reference numeral 3 denotes a case body of a drive device mounted on the chassis 1, which is formed into a splittable housing. Inside this case body 3 is a mainspring 4 that forms the power part.
A hoisting gear group 5 and a driving gear group 6 are built-in. Reference numeral 7 denotes an axle rotatably supported by the case body 3. A gear 8 that meshes with both gear groups 5 and 6 is fixed within the case body 3, and a rear wheel 9 is attached to both axle ends. The rotation ratio of the drive gear group 6 is configured such that the rear wheel 9 rotates 14 times when the mainspring shaft 4a rotates once. Therefore, when the traveling body is pulled back, the mainspring 4 is wound up via the rear wheel 9 and the winding gear group 5, etc., and when the hand is released from the traveling body, the mainspring 4 is wound back and the mainspring 4 is wound back through the drive gear group 5. The rear wheels 9 are rotated through the wheels 6 and the like to move the traveling body forward.

A governor 10 is connected to the drive gear group 6 via an intermediate gear 11, and has the function of rotating the rear wheels 9 at a low and constant speed. Reference numeral 12 denotes a coil, which is disposed in a space of the case body 1 facing the governor 10 at an appropriate interval. Reference numeral 13 denotes a stopper disposed between the governor 10 and the coil 12, and is provided so as to be swingable by a leaf spring 14. Governor 1
0 is stopped from rotating by pressing against one side of the stopper 13. These governor 10, coil 12, stopper 13, leaf spring 14, etc. constitute a braking device.

In addition to the brake device using the governor described above, it is also possible to use a normal stopper member consisting of a plunge pin and a plunge hole.

Reference numeral 15 denotes a printed circuit board fixed to the side surface of the case body 3, on which the coil 12 protruding into the inside of the case body 3 and a normally closed switch 16 are installed at the bottom, and various components constituting the receiving device 17 are installed at the top. Electronic components are mounted above the case body 3. Reference numeral 18 denotes a separating member of the switch 16, which is fixed to the mainspring shaft 4a. Note that 19 is a front wheel, which is attached to the chassis 1 so as to be rotatable and changeable in direction.

3 and 4 show examples of circuits of the receiving device 17 that outputs electrical control signals to the braking device, and both operate only by receiving an impulse signal from a transmitting device (not shown). this house,
The circuit shown in Figure 3 using SCR has a power supply voltage of
It is used when the power supply voltage is 1.5V or more, and the circuit shown in Figure 4 using a normal transistor is used when the power supply voltage is 1.5V or higher.
Use when the voltage is 1.5V or less. 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 12 is automatically cut off after a certain period of time, and the stopper 1
3 stops the cabana 10 from rotating. Therefore, the normally closed switch 16 is not required in this case.
The signal between the transmitting device and the receiving device may be a radio wave, a sound wave, or a light wave, and no matter which signal is used, it is sufficient that the transmitting device can transmit an impulse signal. Therefore, the transmitting device can be made simple and compact using a piezoelectric element or the like, and is extremely easy to operate, and the receiving device 17 can also be made simple as described above.

FIG. 5 shows an external side view of a second embodiment of the present invention, in which a surfboard or the like forming the accessory 20 has a printed circuit board 15 or a battery for the receiving device 17 built therein. In this way, the traveling body itself can be further downsized.

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

The running body is brought into pressure contact with the running surface to carry out rearward pulling, and driving force is stored in the mainspring 4 via the hoisting gear group 5. Next, when you take your hand off the running body and place it on the running surface, the drive gear group 6 is activated by the driving force of the mainspring 4.
tries to rotate. However, at this time, since no current is flowing through the coil 12, the stopper 13 is pressed against the side surface of the cabana 10 by the elastic force of the leaf spring 14, and the driving gear group 6 is rotated via the cabana 10. This prevents the vehicle from moving and brings the vehicle to a halt. In this state, when a signal is given to the receiving device 17 from the transmitting device, the circuit of the receiving device 17 is activated and current flows through the coil 12. As a result, the coil 12 attracts the stopper 13 against the elastic force of the leaf spring 14, releases the pressure contact of the side surface of the cabana 10 by the stopper 13, and enables the driving gear group 6 to rotate at a constant speed. When the drive gear group 6 becomes rotatable, the driving force of the mainspring 4 rotates the rear wheels 9 at a constant speed, causing the vehicle to start running.

When the traveling body continues to run at a constant speed and the rear wheel 9 rotates 14 times, the mainspring shaft 4a also rotates once and the separating member 18
opens switch 16, cutting off the current flowing through coil 12. By cutting off the coil current, the stopper 13 presses against the side surface of the cabana 10 again to stop the traveling body. Next, when a signal is transmitted from the transmitting device, the traveling body starts and runs again as described above. Therefore, it becomes possible to control the start and stop of the traveling body by remote control.

In addition, in the running toy of the present invention, the release member 18 of the switch 16 is removed, and once the running body starts, it continues to operate without stopping on the way until the driving force stored in the mainspring 4 is exhausted. It is also possible to do this. In addition, the front wheel 1 that can change direction
If you adjust 9 so that it rotates in one direction, you can play in relatively small spaces such as indoors or on a desk. Further, the power section may be any mechanical power means, such as a flywheel, and any type of power storage means can be used.

As described above, according to the present invention, a traveling body can be driven by mechanical power means such as a mainspring, and the traveling body can be started and stopped by a simple transmitting and receiving device and a braking device. By configuring this, it is possible to obtain a remote-controllable traveling toy that is small and has a strong structure. In addition, it is easy to operate and has the advantage that even young children can easily operate it.
