Description

[Detailed Description of the Invention] The present invention is directed to a toy vehicle such as a miniature car, in particular, which incorporates an elastic body as a driving source, and is equipped with a transmission device that transmits the driving force of the driving source to the wheels. This invention relates to a toy car equipped with a tension adjustment device that can be adjusted so that the body is wound evenly in the length direction.

Conventional toy cars such as miniature cars are the first
As shown in the figure, they are toy car models with a total length of about 5 to 10 cm and do not have automatic power, so they cannot run on their own, so they were often simply collected and enjoyed by looking at them.

Therefore, if a miniature car has power and can run automatically, it can become a moving toy, giving it a sense of fluidity and improving its image.

However, miniature cars are quite small and have a total length of 5.
Since the size is 10cm to 10cm, it is not possible to attach a small motor for toys, and if the power of a motor etc. is made smaller and used, it will cost a lot of money, so it is necessary to create a miniature car with a driving power source of a cheap and simple structure. I can't stand it.

Therefore, rubber bands are used as a simple power source, and one or more rubber bands are installed side by side in a miniature car so that they work in series.For example, a gear transmission device transmits the winding force of the rubber bands to the wheels to drive the wheels. A configuration that rotates and drives a miniature car is conceivable.

However, in the above configuration, when winding up the rubber band, if the rubber band is rolled up from a slack state, it is difficult to wind up the rubber band while giving it an even twist.

In particular, as proposed by the present inventor, when a plurality of rubber bands are arranged side by side in a series in a multi-stage manner, if this occurs, the stored energy will decrease, causing a problem.

Moreover, even when energy is released, the above-mentioned kinks cannot be released sufficiently to the end.

The purpose of this invention is to solve the above-mentioned problems, and in a toy car such as a miniature car that runs by the unwinding force of an elastic body, a sliding support that supports the front side of the car body cavity and the elastic body is used. A miniature body having a tension adjusting device that provides an elastic adjustment body between the body and the tension adjustment device that tensions the sliding support body loosely in the space such as the front side so that an even winding force is applied to the elastic body.・The purpose is to provide toy vehicles such as cars.

4 is a crown gear, which meshes with the above pinion 3 and connects the rear wheel 2-
Convert the rotational force of 2 by 90°.

(Note that a bevel gear may be used instead of the pinion 3 and crown gear 4.

) 5 is a hook, which fixes the crown gear 4 to the end of the hook shaft 6, has a retaining part at the tip, and has a fixed support piece 7-1.
．． 7-2 and protrudes into the internal space 1-1 of the vehicle body 1.

Further, an idler wheel 8 is fixed to the hook shaft 6, and the idler wheel 8 is arranged between the fixed support pieces 7-1 and 7-2.

Reference numeral 9 denotes a slidable sliding support body, which is formed into a frame shape.

The sliding support 9 is provided in the space 1-1 of the vehicle body 1 on the side opposite to the fixed support pieces 7-1, 7-2, and fixed to a slidable sliding plate 10.

Although it is not clear in the drawings, the sliding plate 10 is slidably mounted on the inner edge 1-2 of the vehicle body 1.

Of course, instead of this, shallow grooves are provided on both sides near the bottom of the vehicle body 1 in FIG. It may be configured to be slidable.

A hook 11 also passes through the sliding support 9.

A coupling gear 12 is fixed to the hook 11, and the coupling gear 12 is located within the sliding support 9.

The hook 11 is provided so that an engaging part at the tip thereof projects into a space 1-1 in the vehicle body 1 in correspondence with a retaining part at the tip of the hook 5.

The hook 11 rotates around its axis 13.

Bearings 14 and 15 are made of thrust metal or the like and are provided to reduce friction when the hooks 5 and 11 rotate, respectively.

16 is an elastic body made of a rubber band, etc., which connects hook 5 and hook 1.
1 is connected.

Note that the above-mentioned rubber band is not limited to one, but if a plurality of rubber bands are connected in series and used, a strong rotational force can be obtained from a thin rubber band.

In this case, a hook 5.5-1.

Of course, the number of these rubber bands is not limited to one, and a plurality of rubber bands may be connected between each hook.

An idler wheel 8 having a thrust metal 14 is provided on the hook 5.

Hook 11- that engages the last rubber band 16-N in the series
There is no need to provide something corresponding to the coupling gear 12-N at N.

In addition, the coupling gears 8-1.8-2... and 12.12-1.12-2. ... creates a gear ratio greater than 1 between adjacent connected gears in order to overcome the transmission loss due to friction in each gear, hook, rubber band, etc., and to store energy evenly in the rubber bands in the subsequent stages. This is desirable.

Reference numeral 17 denotes an elastic adjusting body made of a rubber band or the like, which is attached to the sliding plate 1.
The sliding plate 10 is attached under tension between the mounting part 18 provided at the center of the shaft body 1 and the mounting part 19 provided on the front side of the shaft body 1, and the entire sliding plate 10 receives tensile force evenly and is indexed to the front side of the vehicle body 1. It works like that.

In FIGS. 3 and 4, the rubber band 17 forms an isosceles triangle with two attachment points 18 and one attachment point 19 so that the sliding plate 10 can be pulled evenly from the two points.

It is also possible to connect the rubber band 17 between the attachment portions 18 and 19 by using the attachment portions 18 and 19 as the midpoints of the attachment sides.

As another embodiment, as shown in FIG. 5, mounting portions 18 and 19 may be attached to the vehicle body 1 and the sliding plate so that a plurality of rubber bands or small wound springs 17 are arranged at equal intervals.
0 and corresponding mounting parts 18 and 19 respectively.
A rubber band or a small coiled spring 17 is engaged in between to apply tension evenly to the sliding support 9.

Reference numeral 20 is a stopper which is attached near the rear wheel 2-2 of the vehicle body 1, and is attached to the pinion 3 so as to be freely engageable and detachable, so that rotation of the rear wheel 2-2 is prevented by engaging with the pinion 3. It has become.

The operation of the present invention will be explained using the above configuration.

As shown in FIG. 3, the rear wheel 2-2 is rotated in the direction opposite to the running direction (indicated by the white arrow) while the rubber band 16.16-1.16-2 is being stretched loosely.

In this case, the stopper 20 is removed from the pinion 3 as shown in FIG.

In FIG. 4, when the rear wheel 2-2 is rotated in the direction of the outlined arrow, the pinion 3 is rotated as indicated by the small arrow.

Since the pinion 3 rotates the crown gear 4 in the direction of the small arrow, the rubber band 16 is wound and twisted in the direction of the black arrow.

As this twisting occurs, the hook 11 also rotates in the direction of the small arrow together with the coupling gear 12.

Therefore, the coupling gear 12- meshing with the coupling gear 12-
1 rotates in the opposite direction (in the direction of the small arrow) to the coupling gear 12, so the hook 11- is integrated with the coupling gear 12-1.
1 also rotates together.

As a result, the rubber band 16-1 connecting the hooks 11-1 and 8-1 is twisted in the opposite direction to the rubber band 16.

Due to the same gear transmission action, the rubber bands 16-2 arranged in parallel are connected to the rubber bands 16-2 by the meshing of the coupling gears 8-1 and 8-2.
and twist in the opposite direction.

Then, as the rear wheel 2-2 rotates, the rubber band 16.1
6-1.16-2 is twisted evenly and the contractile force becomes stronger.

The sliding support 9 is therefore pulled towards the rubber band 16.16-1.16-2 against the tensile force of the elastic adjustment body 17.

Since the sliding support 9 is slidable back and forth via the sliding plate 10, the sliding support 9 slides rearward.

In the winding operation of the rubber bands 16, 16-1, 16-2, as shown in FIG.
1. Even when 16-2 is not twisted, the elastic adjustment body 17
Since a loose tension is applied to the rubber band 16.16-1.16-2, even if the winding operation progresses and the twisting becomes stronger, the uniform twisting state is maintained without any uneven twisting.

And the winding of the rubber band 16 is the rubber band 16-1. rubber band 16
-2, but in this case as well, the entire rubber band maintains a uniform twisted state without uneven twisting due to the tension adjustment of the elastic adjustment body 17.

If the stopper 20 is engaged with the pinion 3 as shown in FIG. 4 with the rubber band 16.16-1.16-2 fully wound, the rubber band 16.16-1.16-2 will remain twisted. is held in

Next, when driving the miniature car, press the stopper 2-2 while holding the rear wheel 2-2 with your hand in the state shown in Figure 4.
If you remove it from the pinion 3, place it on the ground or other running surface, and release your hand, the rear wheel 2-2 will release a rubber band 16.16-1.16-
It rotates forward due to the unwinding force of 2.

The miniature car then runs forward.

The rubber bands 16.16-1.16-2 can be installed and replaced by removing the upper part of the vehicle body 1.

Up to now, the case of rear wheel drive has been described, but if the front and rear of the vehicle body 1 are reversed and the rubber bands 16, 16-1, 16-2 are wound in the opposite direction, front wheel drive will be achieved.

Further, although a gear connection is used as a transmission means, it is also possible to use a friction wheel instead of a gear.

Instead of removing the upper part of the vehicle body 1, it is also possible to punch out the bottom of the space 1-1 or use it as a cover to replace the rubber band from the bottom.

As explained above, the present invention uses the unwinding force of an elastic body such as a rubber band as a driving force, and supports one end of the elastic body in a toy vehicle such as a miniature car equipped with a simple gear transmission device. A tension adjustment device is provided in which a sliding support is slidable in the longitudinal direction of the elastic body, and an elastic adjustment body is attached to apply a tensile force in the front direction of the vehicle body cavity so that an average winding force is applied to the elastic body. Because of this, the unwinding force is accumulated as an equal unwinding force over the entire length of the elastic body.

By releasing this unwinding force, the wheel is rotated, so the elastic body does not wind unevenly due to the generation of kinks, and the elastic body is partially strengthened due to the uneven force caused by the kinks. The affected area no longer ages or cuts prematurely.

Also, the even rewinding force makes running smoother.

As a result, it has become possible to obtain a moving toy car, such as a miniature car, which is inexpensive and easy to operate.
