Embodiment Hereinafter, this invention will be explained with reference to drawings showing an example of implementation.A toy car 1 has front wheels 2, rear wheels 3,
and a lower half shell 1a equipped with a traveling mechanism 5 such as a full power drive mechanism 4 related to the rear wheels, and the traveling mechanism 5.
It consists of an upper half shell 1b equipped with a lever 7 that moves along a pattern operation guide hole 6 adapted to the pattern operation guide hole 6 and selectively operates the traveling mechanism 5.

When the toy car 1 is moved backward, the rear wheel 3 acts as a winding wheel that winds up the whole body 8 with its rotation, and on the other hand acts as a driving wheel when the toy car 1 moves forward due to the discharging action of the whole body. .

The full-length drive mechanism 4 is installed in a machine frame 9, on which a rear axle 10 with the rear wheels 3, 3 attached at both ends is supported, and an axle gear 11 is fixed on the axle. Two-stage gear 12 bearing
The large-diameter tooth portion 12a meshes with the large-diameter tooth portion 12a of the
a meshes with the small diameter gear portion 15 of the complete shaft 14 via the input clutch gear 13. The clutch gear 1
3 has its base end supported on a shaft concentric with the two-stage gear 12,
and a stay 16 equipped with a balancer 16b at the tip
When the axle gear 11 is transmitted and rotated by the rear wheels 3, 3 rotating backward, the stay 16 rotates the clutch gear 13, with the weight of the balancer 26b assisting its action. It is provided so as to mesh with the small diameter gear portion 15 on the winding shaft 14 to securely wind the entire winding 8.

Above the small-diameter tooth portion 12b of the two-stage gear 12, both ends are supported by vertical holes 19, 19 on the machine frame 9, and the entire gravity lowers the small-diameter tooth portion 12b and engages with the small-diameter tooth portion 12b of the two-stage gear 12. An output clutch gear 17 is provided with a large-diameter tooth portion 17a that engages with the large-diameter tooth portion 17a and a small-diameter tooth portion 17b that meshes with the large-diameter gear portion 18 on the full shaft 14.

A spin fulcrum plate 2 is attached to the bearing tubes 20, 20 for the rear axle 10 that protrude laterally from the outer surfaces of the left and right side walls of the machine frame 9.
1 and 21 are bearings, and claws 22 and 22 protruding from the lower edges of their respective front ends are engaged with the back sides of the rear ends of spring plates 22 and 23 whose front ends are fixed to the inner bottom surface of the lower half shell 1a, and are engaged by spring pressure. Holding the fulcrum plates 21, 21 as required,
The rear edge of each lower end is always housed inside the lower half shell 1a, and an engaging element 2 is provided at the upper edge of each of the fulcrum plates 21, 21.
4 and 24 are formed to protrude inward.

A support shaft 25 is provided across the rear upper half of the machine frame 9, into which the base end bearing tube 27a is fitted, and above the shaft portion 12c of the input clutch gear 13, the side surface is bifurcated and the lower side is Short brake shoe part 27b
A brake lever portion 27c having an elongated upper side is formed.

The operation guide hole 6 formed in the upper half shell 1b corresponds to the full movement driving mechanism 4, and a vertically elongated balance operation guide hole 6a is provided in the front-rear direction at the center of the upper half shell, so that the front end side is for normal travel, and the rear end is for normal travel. The side runs on a stand, and the left and right horizontal communication holes 6b1, 6 are installed at appropriate locations near the rear half.
c1 is opened, left and right rear operation guide holes 6b, 6c are opened rearward at both ends of each, provided for left or right spin, and a front operation guide hole 6d is opened forward from the right side guide part 6c, Provided for automatic fixed distance stopping.

The lever 7 has a shaft portion 7a loosely fitted into the guide hole 6, whose lower end is used as an operating shaft and projects downward a required length, and has an upper collar portion 7b and a lower presser foot 7.
c lightly compresses the upper half shell 1b of the guide hole 6 portion.

Incidentally, the pitches of the winding gear group of the full-length gear 8 and the bullet transmission gear group are changed in order to adapt them to the two-stage gear 12 at the final stage.

Since this device has the above-mentioned configuration, by holding the toy car 1 and moving it backwards, the rear wheels 3, 3 can be rotated to tighten the full length 8, and then the lever 7 to the guide part 6a of the guide hole 6
When set at the front end, the weight of the lever 7 causes the center of gravity of the toy car 1 to be set midway between the front wheels 2 and the rear wheels 3, and the lower end of the shaft of the lever 7 is free from engagement, such as the engager of the traveling mechanism. Since the vehicle is in this state, the rear wheels 3, 3 suddenly receive the full force of the full movement 8, and the vehicle runs straight ahead at full speed. Next, when the lever 7 is slid to the rear end and set, the center of gravity of the toy car 1 moves to the rear of the rear wheels 3, 3 due to the influence of the lever 7, and the front end of the toy car 1 moves upward. It is in a stunt position with its rear edge touching the ground.

Therefore, if you release your hand in this state, the vehicle will run at full speed with its front end raised. and,
When the lever 7 is set in the guide portion 6b, the shaft portion at the lower end abuts against the engager 24 of the right fulcrum plate 21, so that it is rotated rearward about the bearing sleeve 20. Therefore, the rear lower edge of this fulcrum plate projects downward from the rear outer bottom surface of the lower half shell 1a, as shown by the phantom line in FIG. Therefore, since the lever 7 is set rearward, the center of gravity of the toy car 1 is shifted to the rear wheels 3,
3, the front end of the toy car 1 is raised, and the right wheel 3 is raised above the floor by the fulcrum plate 21. Therefore, when the presser foot of the toy car 1 is released, the toy car 1 spins to the grounding point of the fulcrum plate 21. Next, when the lever 7 is set in the guide portion 6c of the guide hole 6, the turning direction is reversed and changed to clockwise rotation, and a similar spin running is performed.

Next, when the lever 7 is extended to the front end and set in the guide part 6d, the lower end of the lever 7 curves downward from the upper surface of the brake lever 27c and presses down, so the brake lever 27b is gently attached to the shaft part 17c of the clutch gear 17. Pressure contact. In this lever state, if you move the toy car 1 backwards, you can tighten the lever 8 in the same way as the other levers 7 in the set position, and when you release your hand, the action of the lever 8 will cause the rear wheel to tighten through the output clutch gear 17. 3, 3 rotates, and the toy car 1 runs at full speed. However, once the full length 8 is unwound, the motor runs due to inertia, but since braking is applied directly to the output clutch gear 17, the output clutch gear 17 will stop suddenly even if it is for a slight braking action. This creates a large braking resistance for the rear wheels 3, 3 through the transmission gear, and the toy car that runs at full speed suddenly stops at a predetermined position.

From the above, according to this invention, by sliding and setting the lever protruding from the top surface of the vehicle body, the driving mode can be changed in various ways, and a wide variety of play activities can be performed with a single vehicle.
