Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a remote starting unit device that enables remote control of a small traveling toy that is driven by power from a spring.

[Technical Problem] Conventionally, various small running toys such as automobiles that are driven using spring power have been provided. These have a structure in which the mainspring in the built-in mainspring unit is wound up by pulling the wheel backwards with the wheel pressed against the floor, and then the mainspring's unwinding driving force is used to drive the machine when the hand that is holding it is released. It's summery.

By the way, with this type of small running toy, if you release your hand from holding it down after winding up the mainspring by pulling backwards as described above, it will start running on its own, and if you take the wheels off the floor, the wheels will spin and the mainspring will return. Put it away. Therefore, if you want to wait some time after winding the mainspring to compete with other running toys, or if you want to run it in another location, you must hold the wheels to prevent it from spinning, which is troublesome and makes it difficult to play. It cut the fun in half. In order to eliminate this inconvenience, it may be possible to incorporate a device that has a stopper that stops the wheels and can remotely control the stopper to start the wheels. There was a problem in that the structure and design of the traveling toy had to be significantly changed.

[Means for Solving Technical Problems] A remote starting unit device of the present invention that solves the above technical problems includes a stopper that stops the rotation of a drive wheel of a traveling toy, and a release mechanism that releases the stopped state of the drive wheel caused by the stopper. and a signal receiving section for operating the release means in response to a signal from a starting machine;
The signal receiving section is integrally provided on the circuit board, and the structure is such that it can be detachably attached between the body and chassis of the traveling toy.

In more detail, the body and the chassis equipped with a spring unit are combined to enable remote control of a traveling toy that runs using the spring as power, and a pulse signal is received via the antenna section. A circuit board on which a receiving circuit is mounted is placed between the body and chassis of a traveling toy and is configured to be attachable to a power unit, and a stopper made of an elastic material is fixed at one end to the circuit board and raised and lowered. The stopper has an electromagnet and an electromagnet provided on the circuit board as a release means. Magnets are mounted facing each other at a constant interval, and when the magnets and electromagnets are attracted, the other end of the stopper contacts the wheel, and the stopper is pressed from above against its elastic force. A pressing means is provided so that the other end contacts the wheel and the magnet is attracted to the electromagnet, and the attraction between the magnet and the electromagnet is released by receiving a pulse signal from the signal receiving circuit.

Further, a front wheel 3 is rotatably attached to the chassis 1. 5 is a body fixed on the chassis 1. With this structure, when the rear wheel 4 is pressed against the floor and pulled backwards, the mainspring inside the power unit 2 is wound up, and when the hand holding the hand is released, the rear wheel 4 rotates due to the drive of the mainspring and the vehicle runs. be. The structure of this traveling toy is the same as that provided conventionally.

10 is a remote starting unit device according to the present invention. This remote starting unit device 10 mainly consists of a fixing circuit board 11 constituting a signal receiving section and a stopper 16 that stops and releases the rear wheel 4.
The fixing circuit board 10 is removably attached to the power unit 2 with screws or the like and housed between the chassis 1 and the body 5 as shown in FIG. In addition, a gear 2 constituting the power device 2 is usually disposed on the power device 2.
Since a part of A protrudes as shown in the figure, a notch 14 is provided in the fixing circuit board 11 so that it does not come into contact with the gear 2A when it is mounted on the power unit 2.

FIG. 3 is a perspective view of the fixing circuit board 11.
Mounted on the fixing circuit board 11 are electronic components 12 such as transistors constituting the signal receiving circuit shown in FIG. 5, an electromagnet 13, and a mercury battery 20 serving as a power source. The mercury battery 20 is connected to the fixed circuit board 1 by contact plates 21 and 22 as shown in FIG.
It is integrally attached to 1. FIG. 6 is a block diagram of a transmitter 30 that sends a one-shot pulse signal to the signal receiving circuit, and is composed of a piezoelectric element 32 for generating the one-shot pulse signal, an operation button 32, and an antenna 33. When the one-shot pulse signal sent from the transmitter 30 is received by the antenna section of the signal receiving circuit shown in FIG. 5, current flows from the mercury battery 20 to the electromagnet 13 due to the operation of the transistor, and the electromagnet 13 is connected to the electromagnet 13 as shown in FIG. It is excited for a certain period of time in the direction of polarity.

The stopper 16 is made of a resilient material such as metal and is formed into a substantially T-shape as shown in FIG. 4, and is fixed onto the fixing circuit board 11 at one end 16B. The portion from one end 16B to the other end is bent upward by a certain angle as shown in FIG. are doing. Further, the other end portion 16A is located substantially above the left and right rear wheels 4 with a predetermined distance therebetween.
Due to this structure, if the stopper 16 is pushed downward using one end 16B as a fulcrum, the other end 16A
When it comes into contact with the rear wheel 4, it acts as a brake. Further, a magnet 17 is attached to the lower surface of the other end portion 16A at the substantially center thereof, and this magnet 17 is located opposite to the electromagnet 13 on the fixing circuit board 11 with a constant distance therebetween. Further, this magnet 17 is attached so that its polarity is in the same direction as the polarity of the excited electromagnet 13.

Also, the magnet 1 of the stopper 16 on the top surface of the body 5
A push button 18 is installed through a hole 19 at a location opposite to the mounting portion 7, as shown in FIGS. 1 and 2. This push button 18 is a stopper 16
In a normal state where the rear wheel 4 is not stopped by the stopper 16, it is always pushed upward by the stopper 16, as shown in FIG.

As described above, the remote starting unit device 10 of this embodiment has a fixing circuit board 11 constituting a signal receiving section.

Moreover, it can be freely attached to and detached from the above-mentioned traveling toy. Therefore, it is possible to attach the conventional traveling toy as is without making any changes to the structure, design, etc. of the toy.

Next, the operation of the traveling toy equipped with the remote starting unit device 10 will be explained.

First, the magnet 16 of the stopper 16 shown in FIG.
The mainspring in the power unit 2 is wound up by pressing the rear wheel 4 against the floor or the like and pulling it back in a state where it is separated from the electromagnet 13. After winding up the mainspring, when the push button 18 on the top surface of the body 5 is pushed down, the magnet 17 of the stopper 16 is attracted to the electromagnet 13. When the magnet 17 is attracted to the electromagnet 13, the other end 16A of the stopper 16 comes into pressure contact with the rear wheel 4 to stop rotation, so even if the rear wheel 4 is removed from the floor, the mainspring of the power unit 2 will not move. It does not return and remains wound up.

Next, to start the traveling toy, the operator presses the operating button 32 of the transmitter 30 shown in FIG. 6 to send a one-shot pulse to the signal receiving section of the remote starting unit device 10. When the one-shot pulse signal is received, current flows through the electromagnet 13 for a certain period of time, as described above, and the electromagnet 13 is excited. At this time, the electromagnet 13 is excited with the same polarity as the magnet 17, so the attracted magnet 17 separates from the electromagnet 13, and the stopper 16 pushes up the push button 18 due to its elasticity and returns to its original position. As a result, the stopped state of the rear wheels 4 is released, and the running toy starts running due to the drive of the mainspring.

As described above, if the remote starting unit device 10 of this embodiment is used, it is possible to start a small traveling toy by remote control while keeping the mainspring wound up, making it even more interesting. For example, it becomes possible to play by lining up multiple cars and starting them at the same time to compete for speed.

The remote starting unit device 10 includes a fixing circuit board 11 and a stopper 1 constituting a signal receiving section.
6 has an integral structure and can be detachably attached to existing small-sized traveling toys as is, so there is no need to change the structure, design, etc. of the incorporated traveling toy.

[Effects of the invention] Since the remote starting unit device, which stops and releases the rear wheels by remote control, is integrated with the fixing circuit board that constitutes the signal receiving section and the stopper, it can be attached to and removed from conventional running toys as is. It can be installed without changing the structure or design of conventional traveling toys. Moreover, this has the advantage that it is possible to have a variety of play with conventional traveling toys, and it can be obtained at low cost.
