Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a toy vehicle drive and starting device that rotationally drives a unicycle or two-wheeled toy vehicle to start running.

[Conventional technology]

Conventionally, a rear wheel drive gear of a two-wheeled toy vehicle is meshed with a manually rotated drive gear of a starting platform.
There is known a toy car drive and starting device disclosed in Japanese Utility Model Application Publication No. 104794/1983, which is configured to rotationally drive the rear wheels of the toy car through the engagement and interlocking of the drive gears to start the two-wheeled toy car. There is.

[The problem that the idea aims to solve]

The conventional toy car drive starting device meshes the rear wheel drive gear of the toy car with the drive gear of the starting platform to rotate the rear wheels in the forward direction of the toy car. This requires a transmission device to transmit the rotation of the rear wheel drive gear to the flywheel, which has the disadvantage of complicating the structure of the toy car. Moreover, in a toy car starting device that uses a rotary drive system based on engagement of drive gears, a backward thrust is generated on the toy car due to the relative drive rotation of the drive gears, so it is necessary to prevent the toy car from moving backward due to this thrust. , a pair of support walls located on both sides of the entry area of the starting platform are formed with cutouts whose ends in the direction of travel of the toy car are open, and projecting pins on both sides of the vehicle body of the toy car are engaged with the support wall cutouts; It is necessary to support the toy car in an inclined state where the rear wheels are separated from the stand, which complicates the structure of the starting device. In addition, it is necessary to mesh the rear wheel drive gear of the toy vehicle with the drive gear of the starting platform, and it is also necessary to maintain this state when starting rotation, which makes the operation extremely troublesome. There is a problem.

[Means to solve the problem]

In order to solve the problems of the conventional device, this invention targets a device for driving and starting a toy vehicle such as a unicycle or two-wheeled vehicle having a large running wheel that functions as a flywheel. A wall structure is provided to prevent the vehicle from overturning, and a vehicle starting path is provided that extends laterally from the vehicle compartment between the wall structures, and a small motor rotates at high speed in the upper opening of the platform. The turntable is provided with a circumferential portion of the table partially exposed at the bottom of the compartment so that the running wheels of the toy car placed in the compartment can be rotated in the forward direction. It is characterized by the fact that it is located at

[Effect]

The toy car drive/start device having the above configuration includes a toy car placed between the wall structures, the running wheels of the toy car placed on a turntable, and the turntable rotated at high speed by a motor. The wheels are rotationally driven in the forward direction of the toy vehicle by the rotation of the turntable. Then, when the rotation of the wheels reaches a high speed, when the toy car is pushed with its tail toward the starting road, the toy car is launched at high speed from the starting road onto the floor due to the inertial rotation of the running wheels and travels far away. I come to do it.

〔Example〕

An embodiment of this invention will be described below with reference to the drawings. This toy car drive starting device is a two-wheeled vehicle having a heavy metal running wheel 1 that functions as a flywheel (the front wheel 2 is a lightweight plastic wheel). The toy car 3 is rotated and started, and wall structures 5 and 6 are provided on the base plate 4 to prevent the toy car 3 from overturning, and a wall structure 5 and 6 is provided between the wall structures 5 and 6. A vehicle launch path 8 is provided which extends laterally from the vehicle compartment 7 and whose sloping tip abuts on the floor surface, and a disc-shaped vehicle is provided in the upper surface opening 4a of the base plate 4, which is rotated at high speed by a small motor 9. It is configured such that a turntable 10 is provided. Note that this turntable 10 is arranged in such a manner that a part of the circumferential surface of the table is exposed on the bottom surface of the vehicle compartment 7.
Move the running wheels 1 of the toy car 3 placed in the forward direction (fourth
It can be rotated in the direction of the arrow in the figure. A small motor 9 for rotating the turntable 10 is held in a motor holder portion 12 of a battery box 11 fixed inside the wall structure 6, as shown in FIG. Reference numeral 13 indicates a battery housed in the battery box 11, and reference numeral 14 indicates a switch for operating and stopping the motor 9.

In the case of this embodiment, the wall structure 6 is shaped like a gas pump at a gas station, and the wall structure 5 on the front side is shaped like a parking embankment with a triangular cross section.

Thus, the toy car 3 is placed between the wall structures 5 and 6.
into the car as shown by the imaginary lines in Figures 3 and 4, and place the running wheel 1, which is the rear wheel, on the turntable 10.
When the turntable 10 is rotated at high speed in the direction of the arrow in FIG. 1, the rotation of the table rotates the wheel 1 in the forward direction shown by the arrow in FIG. When the rotation of the wheels 1 reaches a high speed, the toy car 3 is pushed toward the starting path 8 by pushing the toy car 3. Due to the inertial rotation of the running wheels 1, the toy car 3 moves from the starting path 8 onto the floor at high speed. It will start and travel far away.

Note that the toy vehicle 3 is not limited to the two-wheeled vehicle described in the embodiment, but may be a one-wheeled toy vehicle such as a one-wheeled bicycle.

[Effect of idea]

Since the toy car drive starting device of this invention rotates and drives the running wheels of the toy car by placing them on a turntable, it is not necessary to equip the toy car with conventional wheel drive gears and transmissions. Therefore, the structure of the toy car can be simplified, and a simple toy car having running wheels functioning as a flywheel can be driven and started by the rotation of the turntable. Moreover, the toy car starting device that uses the high-speed rotation of the turntable does not generate thrust (the thrust that acts to move the toy car backwards) unlike the conventional toy car starting device that uses the meshing drive gear method. It is not necessary to provide a conventional restraining means to prevent backward movement and support the wheels in a lifted state, and the structure of the device can be simplified accordingly, and the toy vehicle can be easily started. play.
