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 Problem] 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 wheels while pressing them 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.

[Means for solving the technical problems] The driving wheel stopper structure for a traveling toy of the present invention that solves the above problems stops and releases the driving wheels of a traveling toy that runs using a mainspring as power. A stopper with a generally gate-shaped cross section that extends over the drive wheel is provided so as to be able to approach and separate from the drive wheel, the stopper has presser portions at lower ends of both ends for pressing the drive wheel to a stop, and the stopper has a stopper that presses and stops the drive wheel A pressure holding means is provided for temporarily holding the presser state, and the pressure holding means is configured by attaching and detaching a magnet and an electromagnet to the stopper and the toy body, and is detachable upon receiving a signal from the transmitter. Then, the above pressure is released.

[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 stopper structure according to an embodiment of the present invention is applied, and 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 integrally constructed from 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, since a part of the gear 2A constituting the power unit 2 normally protrudes from the power unit 2 as shown in the figure, it does not touch the fixed circuit board 11 when it is installed on the power unit 2. Notch part 1
4 is provided.

FIG. 3 is a perspective view of the fixing circuit board 11. The fixing circuit board 11 has electronic components 1 such as transistors constituting the signal receiving circuit shown in FIG.
2. An electromagnet 13 and a mercury battery 20 as a power source are respectively mounted. The mercury battery 20 is integrally attached to the fixing circuit board 11 by contact plates 21 and 22, as shown in FIG. FIG. 6 is a block diagram of a transmitter 30 that sends a one-shot pulse signal to the signal receiving circuit, including a piezoelectric element 32 and an operation button 32 that generate the one-shot pulse signal.
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 other end from one end 16B is bent upward by a certain angle as shown in FIG. It is located prominently in A rear wheel presser 16A is formed at the tip of the other end extending in the left and right directions. Further, this rear wheel presser 16A is located substantially above the left and right rear wheels 4 at a predetermined interval, as shown in FIGS. 2 and 7. Due to this structure, when the stopper 16 is pushed downward using one end 16B as a fulcrum, the other end 16A comes into contact with the rear wheel 4, thereby acting 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 button 18 is mounted through a hole 19 at a location facing the mounting member 7, as shown in FIGS. 1 and 2. In a normal state where the rear wheel 4 is 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 drive 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 modifications to the structure, design, etc. of the conventional traveling 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 other end 16A of the stopper 16 presses against 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 return. It remains unwound.

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 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, the present invention provides a means for pressing and holding a stopper, which stops the rotation of the drive wheels by pressing the presser part so as to be able to approach and separate from the left and right drive wheels of a traveling toy, using magnets and electromagnets. Since the mainspring of the traveling toy can be temporarily maintained in a wound state, it can also be operated remotely by transmitting a signal from the transmitter, making it possible to play with the traveling toy. The range expands and the interest increases.
