Description

[Detailed description of the invention] The present invention relates to a tricycle toy, and in particular, a tricycle toy that can turn several times while traveling straight, change direction, and then run straight again, drawing an overall loop-shaped trajectory. It is related to.

Hereinafter, FIGS. 1 and 2 will explain the details of the present invention together with the embodiments shown in the drawings. FIGS. 1 and 2 illustrate the entire toy tricycle according to the present invention. It consists of a doll 3 fixed to this.

On both sides of the front wheel 4 of the main body 2, pedals 5 forming cranks are attached with a phase difference of 180 degrees, and the soles of the feet 6 of the doll 3 are in contact with each pedal 5.

The bases of the legs 6 are rotatably supported on the doll 3 side via pins 7, and move up and down as the pedals 5 rotate, as if pedaling a tricycle.

On the other hand, the doll 3 is formed hollow, and a drive mechanism as shown in FIG. 3 is housed inside the doll 3.

That is, what is indicated by reference numeral 8 in FIG. 3 is a mainspring unit, which houses a mainspring (not shown) and a plurality of gears that sequentially mesh with gears fixed to the mainspring shaft. The rotating shaft can be led out of the unit case and used as an output shaft for any reduction ratio.

A drive shaft 9 is provided in a part of the mainspring unit 8 so as to protrude from both sides, and a drive wheel 10, which is a rear wheel, is fixed to both ends of the drive shaft 9.

One end of the actuating lever 11 is rotatably supported by the driving wheel 9, and the other end of the actuating lever 11 is a bent portion 11a bent downward in an L-shape.
Its lower end faces downward from an opening 12 a formed in the bottom plate 12 of the tricycle main body 2 at a position near one of the drive wheels 10 .

In addition, from the middle of the operating lever 11, the pillar 1
1b protrudes, and a spring 14 is stretched between the middle of this support 11b and a pin 13 protruding from the side of the mainspring unit 8, and the entire operating lever 11 is shown in FIG. A rotational force is applied so as to rotate in a clockwise direction, so that the bent portion 11a is configured to escape upward from the opening 12a.

On the other hand, a mainspring shaft 15 extends outwardly through the body of the doll 3, and a knob 16 for winding the mainspring is fixed on the outside of the doll 3.

A cam 17, illustrated as a triangular cam, is fixed to the base of the mainspring shaft 15, and when the side edge of the cam 17 in the longer diameter direction comes into contact with the support column 11b, the operating lever 11 is moved by the spring 14.
3 in the counterclockwise direction in FIG.
a is made to protrude downward from the opening 12a and reach below the drive wheel 10.

Next, the operation of this embodiment configured as above will be explained.

First, when the mainspring winding knob 16 is turned to fully wind the mainspring and the toy tricycle 1 is placed on the floor, the drive wheels 10 rotate due to the unwinding force of the mainspring and start traveling straight.

At the same time, the spring shaft 15 also rotates, the cam 17 rotates,
When the side edge in the long diameter direction comes into contact with the side surface of the column 11b of the actuating lever 11, the entire actuating lever 11 is moved by the spring 14.
The bent portion 11 a projects downward from the opening 12 a of the bottom plate 12 of the tricycle main body 2 and reaches below the drive wheel 10 .

As a result, the drive wheel 10 located near the bending portion 11a
rises above the floor.

Therefore, the toy tricycle 1 repeats circular motions by the driving wheel 10 on the grounded side, centering on the tip of the bent portion 11a.

This circular motion occurs while the cam 17 is in contact with the support column 11b.
That is, it continues while the bent portion 11a protrudes below the drive wheel 10.

Then, when the bent portion 11a is retracted upward, the drive wheel that has been floating until now comes into contact with the ground, and the toy tricycle 1 starts running in a straight direction different from the straight ahead direction.

Thereafter, the same operation is repeated.

As is clear from the above description, according to the present invention, a running toy that intermittently repeats straight running and turning running can be obtained with an extremely simple structure consisting of a combination of a cam driven by a spring and an operating lever. I can do it.
