Description

[Detailed description of the invention] The present invention relates to a direction changing device for a running toy, and in particular provides a direction changing device for a running toy configured so that the running toy can run in a figure 8 pattern. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the device of the present invention will be explained below along with the embodiments shown in the drawings.

FIG. 1 illustrates the appearance of a running toy to which the device of the present invention is applied, and is exemplified as a hand trolley.

That is, the running toy, which is generally designated by the reference numeral 1 in the figure, consists of a running toy main body 2, which is exemplified as a hand trolley, and a doll 3 imitating a boy attached thereon in a prone position.

One hand of the doll 3 is placed on a hand lever 4.

A drive mechanism as shown exploded in FIG. 2 is accommodated within the traveling toy main body 2.

That is, in FIG. 2, the reference numeral 5 is a mainspring unit, which houses a mainspring and a plurality of gears that sequentially mesh with a gear fixed to its output shaft, although not shown. It is configured such that an output shaft having a desired reduction ratio can be taken out using the support shaft of each gear as an output shaft.

An output shaft 6 protrudes from approximately the center of the mainspring unit 5, and a pinion gear 7 and a gear 8 integrated therewith are fixed to the output shaft. A pin 9 is implanted at an eccentric position on the side surface.

Further, a spring winding knob 10 is attached to the other side of the spring unit 5, and this knob 10 is located on the outside of the traveling toy main body 2.

On the other hand, what is indicated by the reference numeral 11 is a movable leg on one side of the doll 3, and an opening 1 in the middle of which the pin 9 is inserted.
1a is formed, and a long hole 11b is formed in the vertical direction at the upper end.

A pin 12, which is fitted and fixed in a through hole 5a formed at the top of the mainspring unit 5, is loosely fitted into the elongated hole 11a.

The gear 8 meshes with a pinion gear 14 fixed midway on a drive shaft 13 that is rotatably suspended horizontally on the main body 2 of the traveling toy.

Drive wheels 15 are fixed to both ends of the drive shaft 13.

Further, the pinion gear 7 meshes with a gear 17 fixed to a shaft 16 rotatably suspended in the main body 2 of the traveling toy, and a pinion gear 18 is formed integrally with the gear 17.

Further, a shaft 19 is horizontally suspended parallel to the shaft 16 on the traveling toy main body 2 side, and a gear 20 and a disk 21 that mesh with the pinion gear 18 are fixed to this shaft 19. A pin 22 is provided protruding from the outer surface at an eccentric position.

On the other hand, a guide wall 2 is provided at one corner of the bottom plate 23 of the traveling toy main body 2.
4.25 are provided protruding parallel to the direction of travel, and both guide walls 24
．． A slide plate 26 is slidably fitted between the parts 25 and 25.

A notch 27 is formed at the rear end of the slide plate 26 and is open at the top.

As shown in an enlarged view in FIG. 3, the notch 27 has a vertical wall 27a on the rear side and an inclined wall 27b on the front side.

The positional relationship between this notch 27, the front circular plate 21, and the pin 22 is as follows.

That is, the diameter of the circle of the pin 22 is larger than the distance W between the opening edges of the notch 27, and the pin 22 is
Do not touch the lower edge of the

A cylindrical body 28 is integrally protruded on the right side of the tip of the slide plate 26 in the direction of movement, and the lower end of this cylindrical body 28 passes through an arcuate guide hole 29 formed on the bottom plate 23. Steering frame 3 located below the bottom plate 23
It is rotatably fitted into a pin 31 implanted near the end of the top surface of the 0.

The steering wheel 30 is formed in an elongated U-shape, and a rotating shaft 33 is horizontally suspended between brackets L-32 and 32 formed at both ends thereof, and driven wheels 34 are fixed to both ends of the rotating shaft 33. There is.

A protruding piece 35 is provided protruding from the center of the rear end of the steering frame 30, and a pin 36 is protrudingly provided on the protruding piece 35.

A spring 38 is stretched between this pin 36 and a pin 37 protruding from the lower surface of the bottom plate 23, and constantly pulls the steering frame 30 rearward.

This steering frame 30 is connected to the bottom plate 23 by a shaft 39.
It is rotatably supported on the side.

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

First, the wind-up winding knob 10 is turned to place the wind-up traveling toy body 2 of the wind-up unit 5 on the floor.

Then, as the mainspring unwinds, the drive wheel 15 is rotated via the gear 8 and pinion gear 14, and the traveling toy 1 starts running.

At the same time, the shaft 19 is rotated via the gear 17 that meshes with the pinion gear 7 and the gear 20 that meshes with the pinion gear 18, the disk 21 rotates, and the pin 22 rotates.

When the pin 22 is located in front of the bottom or top of the notch 27 of the slide plate 26 shown in FIG.
There is no interference with the slide plate 26, and no movement of the slide plate 26 occurs.

In this state, the steering frame 30 has a spring 3
8 and maintains a neutral position.

That is, it is in the state shown by a in FIG. 4A, and at this time, it maintains a straight traveling state as shown by a with the same reference numeral in FIG. 4B.

Eventually, the pin 22 rotates counterclockwise in FIG. 3, and when it reaches the position indicated by reference numeral A1 in FIG. 28. Rotate the steering frame 30 to the left in the direction of travel via the pin 31 with respect to the arrow X in the middle of FIG.

In this state, the running toy turns to the left as shown in Fig. 4A, Bc7)b.

Eventually, the rotation of the pin 22 progresses, and the pin 22 hits the vertical wall 27.
When the pin 22 moves away from the position a, the pin 22 no longer interferes with the slide plate 26, and the steering frame 30 returns to its original state, that is, the neutral state, due to the tensile force of the spring 38.

This state is state C shown in FIGS. 4A and 4B, and the vehicle is in a straight-ahead state.

Further, as the rotation of the pin 22 progresses, the pin 22 comes into contact with the inclined wall 27b as indicated by the symbol A2 in FIG.

As a result, the slide plate 26 is pushed forward, the steering frame 30 is rotated to the right in the direction of travel, and as shown in FIG.
The state d shown in B is reached, and the traveling toy turns to the right.

Then, the rotation of the pin 22 further progresses, and the inclined wall 27
When the sliding plate 26 is released from the position b, the steering frame 30 becomes neutral due to the tensile force of the spring 38, and the traveling toy 1 starts moving straight.

This state is shown in e of FIGS. 4A and 4B.

In this way, by repeatedly going straight, turning to the right, and turning to the left, the traveling toy repeatedly travels in a figure-of-eight pattern.

As is clear from the above explanation, according to the present invention, by using an extremely simple structure consisting of a combination of a steering frame that is rotated by engagement between an eccentric pin and a notch in a slide plate, the vehicle can repeatedly travel in a figure-of-eight motion. You can get toys.
