Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is a driving wheel stopper for a wind-up toy that enables one-touch running of a wind-up toy by freely stopping and releasing the drive wheel of the toy. Regarding structure.

[Technical Issues] Conventionally, various small running toys such as automobiles that are driven using spring power have been provided. These machines wind up the built-in mainspring by pulling the wheel while pressing it against the floor.
If you release your hand from this state, it will move due to the driving force of the mainspring.

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 moving toys, or if you want to run it in another location, you must hold down the wheels to prevent it from spinning, making it difficult to operate. It was a hassle and cut the fun of the game in half.

The claws are disengaged upon reception of a signal from a transmitter to release the engagement of the claws.

[Embodiments] Hereinafter, the present invention will be described in detail with reference to the drawings showing preferred embodiments.

FIG. 1 is an exploded perspective view of a small traveling toy to which a drive wheel stopper structure according to an embodiment of the present invention is applied;
FIG. 2 is a sectional view thereof.

In the figure, 1 is the chassis of a small traveling toy, 2
is a power device that incorporates a driving mainspring provided in a chassis 1, and a rear wheel 4, which is a driving wheel, is attached to its rotating shaft. 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 it is released, the rear wheel 4 rotates due to the drive of the mainspring. . The structure of this traveling toy is the same as that provided conventionally.

Reference numeral 10 denotes a drive wheel stopper structure that allows the rear wheel 4 to be stopped and released by remote control, and is composed of a fixing circuit board 11 that constitutes 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 is housed between the chassis 1 and the body 5 as shown in FIG. Also,
Normally, a part of the gear 2A constituting the power unit 2 protrudes from the power unit 2 as shown in the figure, so the fixing circuit board 11 is designed so that it does not come into contact with the gear 2A when it is installed on the power unit 2. A notch 14 is provided.

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. 4, 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. 5 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 material such as metal and has an elastic plate shape, and is fixed on the fixing circuit board 11 at one end 16B. The other end from one end 16B is bent upward by a certain angle as shown in FIG. A claw piece 16A is provided for meshing with the gear 2A to prevent rotation. In a normal state, the claw piece 16A is positioned at a predetermined distance from the gear 2A as shown in FIG. With this structure, when the stopper 16 is pushed downward using the one end 16B as a fulcrum, the pawl 16A engages with the gear 2A, thereby stopping the drive of the rear wheel 4 by the power unit 2. Further, a magnet 17 is attached to the lower surface of the other end of the stopper 16, and this magnet 17 is located opposite to the electromagnet 13 on the fixing circuit board 11 at a constant distance. 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
As shown in FIGS. 1 and 2, a button 18 is attached through a hole 19 at a location opposite to the attachment portion 7. As shown in FIGS. In a normal state where the rear wheels are not stopped by the stopper 16, this button 18 is always pushed upward by the stopper 16 as shown in FIG.

As described above, the driving wheel stopper structure 10 of this embodiment has a fixing circuit board 11 constituting a signal receiving section.
and stopper 16 are integrated,
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 button 18 on the top surface of the body 5 is pressed down, the magnet 17 of the stopper 16 is attracted to the electromagnet 13. magnet 1
7 is attracted to the electromagnet 13, the claw piece 16A of the stopper 16 meshes with the gear 2A, and the rear wheel 4
Since the rotation of the power unit 2 is stopped, even if the rear wheel 4 is removed from the floor, the mainspring of the power unit 2 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. 5 and sends 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 returns to its original position due to its elasticity. As a result, the stopped state of the rear wheels 4 is released,
A running toy starts running by being driven by a mainspring.

As described above, if the stopper structure of the present invention is used, a small traveling toy can be started with a single touch by remote control while the mainspring remains 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.

[Effects of the invention] As explained above, in the present invention, the stopper that engages with the gear of the power unit of the traveling toy to stop the rotation of the drive wheel is operated by a locking and holding means using a magnet and an electromagnet. In addition to being able to temporarily hold the winding state of the spring of a traveling toy, it is also possible to make the toy travel by remote control by transmitting a signal from a transmitter, expanding the scope of play with traveling toys and making them more interesting. increase
