Description

[Detailed description of the invention] The present invention relates to a wind-up running toy, and in particular, when pressing a spring-powered toy to move the body of the running toy, that is, the car body, back and forth, the spring moves in both forward and backward movements. It has been improved so that it can be rolled.

This kind of wind-up traveling toy has a structure in which when the car body is moved while pressed against the floor or other running surface, the wind-up wind-up is dynamically involved, and when the car body is released, it is driven by the unraveling force of the mainspring. Toys are already well known.

However, among the above-mentioned conventional wind-up toys of this kind, there are some that wind the spring and run by moving the car body forward, and others that wind the mainspring and run by moving the housing or car body backwards. In either case, since the mainspring is wound only by zero movement in one direction, the car body must be suppressed and moved over a considerable distance, or
Another drawback is that it is extremely difficult to wind up the mainspring, as the body must be moved back and forth many times.

Furthermore, if the button is pressed during the winding operation of the mainspring to force the vehicle body to move in the opposite direction, the meshing of the gear train will become strained, resulting in a fatal defect such as teeth falling out of the gears.

This proposal was made to eliminate all the drawbacks of the conventional wind-up wind-up type traveling toys mentioned above. The mainspring can be retracted in both directions, so the number of suppressing movements can be reduced, and even if the car body is moved in the opposite direction, the mainspring can be retracted safely without damaging the drive mechanism. The purpose of the present invention is to provide a running toy that can be used as a running toy.

The present invention will be specifically explained below with reference to the drawings showing its embodiments.

In the figure, 30 is the body of the traveling toy, ie, the vehicle body, and 31 is the chassis, both of which are connected by appropriate means.

32 is a front wheel, and 6 is a rear wheel.

1 is a senmai drive device installed in the chassis 31 and has the following configuration.

That is, 2° 2' is a frame on both sides, and a spring plate 4 is pivotally supported on a support shaft 3 protruding from the outer side of the frame, and the base end 4' of the spring plate is fixed. At its tip there is a long hole 4"
The axle 7 of the rear wheel 6, which is loosely fitted into the elongated hole 5 having the inclined portion 5' formed at the lower part of the side frames 2, 2', is fitted into this and acts to push down the axle. I'm letting you do it.

Both side frames 2, 2' are separated by a partition plate 8, and each is firmly held by a spacing shaft 9, 9.

10 is a mainspring protection frame protruding from the inside of the side plate 2,
Mainspring 11 is stored inside it and the button is pressed, mainspring 1
The inner end of the mainspring 1 is attached to a mainspring shaft 12 whose shaft ends are supported by both side frames 2.degree. 2', and the outer end of the mainspring is fixed to the side frames.

Reference numerals 13 and 14 indicate gears that are mounted on the mainspring shaft 12 at positions on both sides of the partition plate 8.

As can be seen from FIGS. 1 and 3, the gear 14 is buttoned and meshes with a first floating gear 15, and the first floating gear 15 is in a position where it can mesh with a gear 16 pivotally attached to the axle 7 of the traveling vehicle. It is in.

The shaft 17 of the first floating gear 15 is loosely fitted into a long hole 18 cut in the side plate 2 and the partition plate 8.

As can be seen from Figures 1 and 2, the gear 13 is a gear (
The gear (large diameter part) 19' that is integrated with this gear (small diameter part) is the second floating gear (small diameter part).
The second floating gear (large diameter portion) 20' is disposed at a position where it can mesh with a gear 7' pivotally attached to the transmission shaft 7 of the driven body 6.

Moreover, the shaft 20' is loosely fitted into a long hole 21 formed in the first side plate 2 and the partition plate 8.

In the wind-up running toy configured as described above, when the rear wheel 6 is brought into contact with its contact surface and moved forward by pressing the side plates 2, 2', in the direction of the arrow A, , the mainspring 11 is wound by the meshing system of the gear group shown in the third figure.

In other words, the first floating gear 15 that meshes with the gear 16 has its shaft 17 fitted in the elongated hole 18 and moves downward, thereby meshing with the gear 14 and giving the spring shaft 12 a rotational force that winds the spring. .

Next, when the both side frames 2, 2' are moved backward, a reverse rotational force is applied to each of the gear groups, and at this time, the first floating gear 15
The shaft 17 moves upward along the elongated hole 18 and freely rotates while disengaging from the gear 14.

Moreover, as mentioned above, when the side frames 2, 2' are moved backward in the direction of the winding arrow B, the meshing system of the gear group shown in FIG. 2 is established and the mainspring 11 is continuously wound. .

At this time, the gear 7' mounted on the transmission shaft 7 of the driven body 6 rotates in the direction of the arrow, and the shaft 20'' moves upward along the long hole 21, causing the gear 7' to rotate in the direction of the arrow. Second floating gear 20
′ mesh with each other, and the small diameter part 20 is a gear (large diameter part)
Since the gear (small diameter portion) 19 meshes with the gear 13, the mainspring shaft 12 is turned to wind the mainspring 11.

In the above, when the both side frames 2, 2' are moved forward, and when each gear group is reversed when winding the mainspring in the meshing system shown in FIG. 20'' rests in the arc-shaped elongated hole 21 and moves downward, so it freely rotates while being disengaged from the gear 19'.

At this time, the mainspring 11 is continuously wound by the meshing system of the gear group shown in the third figure, as described above.

When the mainspring 11 is fully wound as described above and the hand is released from the body 30, the frames 2 and 2' on both sides are lifted and the gear 7' is displaced to the position shown by the thin line in FIG. , the gear 7' maintains meshing with the second floating gear 20', and the unrotating force of the mainspring 11 is as follows: gear 13→19→19'→2
It is transmitted to the axle I via 0 → 20' → 7', allowing the traveling toy to travel.

That is, when the button is pressed in Fig. 2, the gear 13 rotates clockwise due to the unrotating force of the mainspring 11, the gears 19 and 19' rotate counterclockwise, and the second
The floating gears 20 and 20' are rotated clockwise, placed in the elongated holes 21, and lifted up, and by releasing the suppression, both side frames 2, 2' float up and are in positions relatively pressed down by the spring plates 4. The gear τ, which is pivotally attached to the rear wheel 60 and the axle 7, and the floating gear 2σ mesh with each other, and the rear wheel is driven to rotate to the left.

At this time, the rotational force is also transmitted to the gear meshing system shown in FIG. 3, but the axle 7 is pressed down by the spring 4 and the gear 15
and 16 are out of mesh, so the rotational force in the opposite direction to gear 7' is not transmitted to gear 16, and the rear wheel rotates 60 times smoothly.

Since the traveling toy according to the present invention is constructed as described above, when the car body is compressed and moved to wind up the mainspring, there is no need to press and move the car body over a long distance in only one direction. The mainspring can be reeled in easily and quickly by simply moving the mainspring in the forward and backward directions within a short distance. Rather, it is a type of mechanism that winds the mainspring by moving the car body only in one direction.In other words, it does not require a clutch, so it is incorporated into ultra-small running toys called miniature cars. It has many beneficial effects, such as being able to reduce the weight and weight.
