SUMMARY OF THE INVENTION It is an object of the present invention to provide a toy with a lot of interest by utilizing a switchless mechanism of a two-pole motor.

[0004]

Means for Solving the Problems A motor shaft of a two-pole motor or a rotary shaft related to the motor shaft has a part of its peripheral surface cut-out insulated.
The C-shaped conductive tube formed on the surface is fitted and supported to stop the motor.
The blade connected to the C-shaped conductive tube,
The blade and the C-shape are installed facing each other so as to contact the notched insulating surface of
An operation switch device for a toy using a direct current two-pole motor as a drive source, which is characterized in that a power supply circuit for a motor constituted by a conductive tube is turned off .

[0005]

Since the present invention is constructed as described above, if the toy is, for example, an automobile toy, when the automobile toy is first pushed, for example, the rotation of the drive wheels is transmitted to the two-pole motor to rotate. , The notched insulating surface of the C-shaped conductive tube passes the blade instantaneously, the rotational force of the motor is maintained, and the drive wheels of the automobile toy are rotated by the energy of the battery. Next, when the driving wheel of the automobile toy that rotates on its own receives a rotational resistance from the outside, the two-pole motor stops due to the rotational resistance . this
Blade contacts Tokimo over motor shaft or with this the cut insulating surface of the C-type conductivity tubes on a rotating shaft associated feeder circuit to the motor is turned off. Therefore, in a car toy, power supply to the motor is automatically stopped.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings. 1 is a DC two-pole motor, a pinion 3 is attached to one end 2a of a motor shaft 2, and its rotation is transmitted through a transmission gear mechanism 4. For example, deceleration is transmitted to the rear axle 5, and drive wheels 6, 6 are attached to the rear axle 5. In the C-shaped conductive tube 7 of the motor 1, the conductive cylinder 9 made of a metal material is fitted to the core 8 provided at the other end 2b of the motor shaft 2 by an insulating member, and the ridge 8a of the core 8 is made conductive. fitted filled into the slits 9a of the cylinder 9, provided with a part of the outer periphery in the insulating portion
It is configured. The two blades 10 and 11 are brought into contact with each other from both sides of the C-shaped conductive tube 7 at a fixed position to make the two-pole motor 1
Is always stopped at a fixed position, one of the blades 10 and 11 is provided so as to ride on the insulating portion and turn off the power supply circuit. The Te shows Suyo 1 smell, battery 12, the operation sound generator 13 is connected to the power supply circuit. In addition, 14 is C type
Another embodiment of the conductive tube is shown, which is a desk type insulating core 1
5, the conductive disk 16 having a part 16a in which a part of the conductive disk is separated is recessed and attached, and the blade 1 is attached from both sides.
7 and 18 are brought into contact, and one of the blades 17 and 18 is
When the DC double pole motor 1 is stopped, it contacts the separated part,
The power supply circuit is provided so as to be turned off. Since the embodiment of the present invention is configured as described above, for example, in the case of a car toy, first, push the car toy to drive the drive wheels 6,
When 6 is rotated several times, it is transmitted to the DC double-pole motor 1 and rotated. Due to this rotation, the DC bipolar motor 1 is rotated by the energy of the battery 12. The toys then run on their own. At the same time, the blades 10 and 11 are connected to the feeding circuit 2 by the conductive cylinder 9.
The battery 12 and the operation sound generator 13 are turned on. Therefore, the operation sound generator 13 can generate, for example, a siren when an automobile toy starts running. The power supply circuit is turned off at the moment when the blades 10 and 11 come into contact with the insulating ridge 8a, but as described above, the operation sound generator 13 operates without any problem. Then, unless the two-pole motor 1 is stopped, it produces a sound.

[0007]

[Effect] Since the present invention is as described above, engine sound, siren and other sound effects and operation can be generated in perfect synchronization with the running of a toy car. We can provide groundbreaking toys that are extremely entertaining.
