Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a toy in which a loop track rolls as a running body runs on the inner peripheral surface of the loop track, and further includes a device for changing the rolling direction.

An object of the present invention is to provide a new toy that has a rolling track and whose rolling direction changes periodically.

Embodiments of the present invention will be described below based on the drawings.

Reference numeral 1 denotes a loop track, which is formed, for example, from a synthetic resin material into an angular and ring shape.
This loop orbit 1 has two pieces facing each other, and a holding plate 2...
The two loop tracks 1 and 1 are assembled with an appropriate distance between them. Reference numeral 3 denotes a running body, such as a locomotive, which is set to run along the inner circumferential track of the loop tracks 1, 1. The front and rear wheels of this locomotive 3 run along the flat surface of the short side of the angled (L-shaped) part of the loop track 1, 1, and are driven by an internal drive source (motor, etc.) while obtaining appropriate friction due to its own weight. It's becoming like that. Reference numerals 4, 4 are auxiliary wheels, which are provided so as to protrude to the left and right of the rear of the locomotive 3, and are in contact with the back surfaces of the short angle sides of the loop tracks 1, 1.
These auxiliary wheels 4, 4 are connected to the locomotive 3 on loop tracks 1, 1.
I try to hold it so that it doesn't fall off.
Reference numeral 5 denotes a driving gear, which is provided so as to protrude from the lower surface of the locomotive 3 so as to be located between the loop tracks 1, 1, and the drive source inside the locomotive 3 is commonly used. It's always rotating.

Reference numeral 6 denotes a bottom plate, which is attached to a position where a portion of the outer periphery of the loop tracks 1, 1 is cut off, so as to straddle the loop tracks 1, 1, as shown in FIG. Reference numeral 7 denotes a rotation shaft, which is attached to the center of the bottom plate 6. A turntable 8 is disposed on the outside of the bottom plate 6, and a driven gear 9 that rotates integrally with the turntable 8 via the rotation shaft 7 is disposed on the inside. The turntable 8 is sized to fit within the cut portion of the loop tracks 1, 1, that is, within the outer circumferential curvature of the loop tracks 1, 1, as shown by dotted lines in FIG.

On the other hand, the driven gear 9 has a meshing surface of 360 degrees or less, and in this embodiment is formed into a substantially semicircular shape as shown in FIGS. 3 to 6. The driven gear 9 is arranged to mesh with the drive gear 5. 10
is an elastic body, such as a spring, and is spanned between the bottom plate 6 and the turntable 8. This spring 10 is adapted to return the driven gear 9 and turntable 8 to their original positions when they rotate relative to the bottom plate 6.

Next, the operation of the rolling direction changing type toy configured as described above will be described.

First, in order to roll the loop track 1, the loop track 1 is installed on a horizontal plane, and the locomotive 3 set on the circumferential track of the loop track 1 is driven. Then, the locomotive 3 runs on the circumferential track of the loop track 1, but since the loop track 1 is not fixed on the surface, the locomotive 3 runs on the loop track 1 while maintaining a constant height on the horizontal plane. rolls straight on a horizontal surface. When the bottom plate 6 of the loop track 1 comes under the locomotive 3 and the turntable 8 comes into contact with the ground, the entire loop track 1 is supported by the turntable 8 and is not in direct contact with the ground. As shown in FIG. 1, the turntable 8 can be smoothly grounded because its size is within the curvature of the outer circumference of the loop orbit 1. At this time, the driving gear 5 of the locomotive 3 engages with the driven gear 9 as shown in FIG. 3, the locomotive 3 is temporarily stopped, and the rolling of the loop track 1 is also temporarily stopped. Then, the driving gear 5 tries to turn the driven gear 9, but
Since the driven gear 9 is fixed to the grounded turntable 8 via the rotation shaft 7, the driving gear 5 itself is caused by its rotational reaction force to rotate the driven gear 9 as shown in FIG. go around. At the same time, since the loop track 1 is not directly in contact with the ground, the rotational reaction force is applied to the loop track 1 via the locomotive 3, and the second
As shown in Figures 4 and 5, the turntable 8
Rotate around the center to change direction. Further, at this time, the spring 10 which is bridged between the bottom plate 6 of the loop track 1 and the turntable 8 is also pulled as shown in FIGS. 4 and 5 as the loop track 1 rotates.

Next, when the driving gear 5 finishes meshing with the 360 degree or less meshing surface of the driven gear 9, the meshing is disengaged, and as shown in FIGS. Then, the drive gear 5 and the locomotive 3 are released, the locomotive 3 starts running again, and the loop track 1 starts rolling again.

Then, the turntable 8 is smoothly separated from the horizontal surface, and the driven gear 9 and the spring 10
, and returns to the original state with respect to loop trajectory 1. Then, the driven gear 9 again faces the meshing surface with respect to the traveling direction of the driving gear 5.

In this way, each time the track 1 rolls and the turntable 8 touches the ground, the rolling direction of the track 1 can be changed and the track 1 can advance.

Note that what has been described above is only one embodiment, and the present invention can also be implemented in the following manner.

A. Make the loop orbit 1 into a shape that can roll on a horizontal surface other than a circle, such as an ellipse, or make the loop orbit 1
By changing the toy into a monorail, automobile track, etc., it is possible to change the rolling action and the running body, and it is possible to make a great change in the playability of the toy. Furthermore, by varying the angle of the meshing surface of the driven gear 9, the rotation angle of the loop track 1 can be varied, making it even more interesting as a toy. Furthermore,
If the rolling direction changing mechanism consisting of the turntable 8 and the driven gear 9 is provided at multiple arbitrary locations on the loop track 1, it is possible to provide diversity in rolling and direction changing movements. can.

B Instead of the locomotive 3, use other running objects such as a four-wheeled vehicle,
Tanks, airplanes, ships, spaceships, etc. can add some interest.

C Furthermore, if a measure is taken to change the elastic force of the spring 10, the rotational speed of the driven gear 9 can be adjusted, and therefore the speed of direction change of the loop trajectory 1 can be changed. .

As described above, this invention is a very interesting toy because the track rolls and the rolling direction changes periodically.
