Description

[Detailed Description of the Invention] The present invention relates to an ultra-small running toy that uses a garbage wheel as a driving source.

In order to increase the capacity of the waste wheel, it is necessary to use a long waste ring, so it is preferable to arrange the waste ring in the longitudinal direction of the chassis. In this case, since the waste wheel is perpendicular to the axle, special gears such as bevel gears or worm gears are required to transmit the rotational force stored in the wheel to the axle. On the other hand, when the wheel is placed in the transverse direction, the wheel is parallel to the axle, so when transmitting the rotational force stored in the wheel to the axle, the general Two flat gears are sufficient, but since long rings cannot be used, there is a drawback that the stored power of the rings is insufficient.

This idea was made in view of the above circumstances.
The purpose is to provide an ultra-compact running toy that has a simple configuration of two common spur gears and a wheel and has sufficient power storage.

An embodiment of the present invention will be described in detail below based on the drawings. FIGS. 1 and 2 are an exploded perspective view and a plan view showing an embodiment of the ultra-compact traveling toy according to this invention. In the figure, 1 is an ultra-compact traveling body imitating a four-wheeled vehicle. The outer shell of this traveling body 1 is composed of a body 2 and a chassis 3.
Locking portions 4, 4 formed at the front and rear portions of the body 2 are removably attached to locking holes 5, 5 provided in the chassis 3 so as to correspond to the locking portions 4, 4. . At the front and rear of the chassis 3, a front wheel axle 8 and a rear wheel axle 9 are rotatably attached to the chassis 3, to both ends of which front wheels 6, 6 and rear wheels 7, 7 are respectively fixed. A driven spur gear 10 is fixed to the rear wheel axle 9. A drive spur gear 12 rotatably supported by a support member 11 is meshed with the driven spur gear 10 . Drive spur gear 12
A hook portion 13 in the shape of a hook is provided protruding from the tip of the support shaft.

A U-shaped locking member 15 having a locking groove 14 formed in the middle portion is provided upright on one side of the chassis 3 in the lateral direction. An L-shaped locking protrusion 16 is provided near the locking member 15 . A rubber band 17 is attached between the hook portion 13 and the locking protrusion 16 with a portion of the rubber band 17 passing through the locking groove 14 and with an appropriate tension.
By passing a part of the rubber band 17 through the locking groove 14 in this way, the rubber band 17 will not come off from the locking member 15 even if it is twisted in either the left or right direction. This is when the ring gom 17 is twisted, the ring gom 17
This is done by tightening one side of the locking member 15 with its own twisting force.

Next, the operation of one embodiment of the present invention will be explained. First, while lightly pressing the traveling body 1, press the rear wheels 7, 7.
When the driving body 1 is frictionally rotated in the rearward direction of the traveling body 1, the rotational force is transmitted to the drive spur gear 12 via the driven spur gear 10. In this way, the driving spur gear 12
The rotational force transmitted to twists the rubber band 17, and energy is stored in the rubber band 17.

The next time the traveling body 1 is to be made to travel, it can be easily done by releasing the pressure on the traveling body 1. The rotational power stored in the wheel gom 17 is the wheel gom 17.
The drive spur gear 12 is rotated in the opposite direction to when the power is stored. The rotational force of the driving spur gear 12 rotates the driven spur gear 10, so that the traveling body 1 moves forward.

In this way, when the traveling body 1 is moved forward, the rear wheels 7, 7 are frictionally rotated in the rearward direction in advance. On the contrary, when it is desired to move the traveling body 1 backward, this is done by first frictionally rotating the rear wheels 7, 7 in the forward direction. In addition, since a part of the waste ring 17 is passed through the locking groove 14, even if the running body 1 is frictionally rotated in either direction, the waste ring 17 twists and moves upward, and the locking member 1
There's no way it's going to fall outside of 5.

As described above, according to the present invention, the garbage ring is attached between the hook part and the locking protrusion via the locking member, so even long garbage rings can be used and sufficient storage force can be obtained. It will be done. It also has the effect of providing an ultra-compact running toy with a simple configuration, requiring only two common gears, both the driven spur gear and the driving spur gear.
