Description

[Detailed description of the invention] Industrial application field The present invention relates to running toys, and in particular allows model cars for racing competitions that run at high speed to run along a predetermined running path without deviating outward from the course. The present invention also relates to a running toy having a structure that allows it to stop smoothly at a goal point.

BACKGROUND TECHNOLOGY In the case of running toys, especially running toys for competitive competitions that are made to resemble the shape of a real race car and run using a motor as a drive source, the cross section must be U-shaped in order to allow the running toys to compete. In other words, a long guide rail of, for example, 20 m or more, with rising walls on both sides, is used, and multiple running toys are run on it.

Problems to be Solved by the Invention However, the above-mentioned conventional traveling toys had the following problems.

Since running vehicles move at very high speeds, if they are driven directly on the road surface, they will deviate from the designated running surface and there will be no competition, so the above-mentioned running roadbed is required, which is expensive. especially,
Running multiple cars in parallel requires a wide running roadbed, which makes it more expensive.On the other hand, it is not possible to compete simultaneously with a single running roadbed, and competition is done by measuring the time using a time watch, but it lacks a sense of realism. .

In the above-mentioned competition, the cars running at great speed to the goal were stopped by people's hands or by bumping into sponges, cushions, etc.
Even so, the impact that the vehicle received caused damage.

Means for Solving the Problems The present invention solves the above-mentioned problems. Namely, a wire guide is provided on the underside of the chassis through which a wire that guides running can be inserted, and a part of the chassis is provided with a The vehicle is characterized by the provision of a switch lever that operates in response to external stress, thereby turning off the electric circuit between the motor and battery that is the drive source, and stopping the rotation of the wheels.

However, in the case of the above-mentioned traveling toy, the traveling vehicle is able to travel at a predetermined course at great speed along the wire stretched on the concrete surface of the road, the floor, etc. without coming off. Moreover, at the goal point, the switch lever can be operated by an appropriate object, which turns off the motor circuit, cuts off the power, and stops the driving force, and at the same time stops the rotation of the running wheels. It is possible to stop the running body.

Embodiments Embodiments of the present invention will be described below with reference to FIGS. 1 to 5.

In the figure, reference numeral 1 denotes a racing vehicle made to imitate an actual racing car. The vehicle 1 is equipped with a battery and a motor (not shown), and is driven by the driving force thereof. 2,2 is the wheel,
3 is a chassis, and wire guides 4, 4 are provided on the bottom surface of the chassis 3. 5 is a wire.
It is sufficient that the wire guide 5 has at least a hole 4a for passing the wire 5 in the front-rear direction, but if possible, a cut groove 4b is formed in a part of the hole 4a as shown in FIG. It is preferable that the wire 5 be configured to be able to be inserted into and removed from the hole 4a via the hole 4b.

Thereby, after the traveling vehicle 1 reaches the goal point, it is convenient to remove the traveling vehicle 1 from the wire 5, hold it by hand, and move it to the starting point several tens of meters ahead. Note that the wire 5 may be any strong thread or string, for example.

Next, reference numeral 6 denotes a switch lever, and its configuration position may be arbitrary, but in the illustrated example, the switch lever 6 is
It is disposed at the front of the chassis 3 and is supported by the chassis 3 so as to be movable back and forth. Front end 6a of switch lever 6
is provided so as to be able to protrude slightly from the front end of the traveling vehicle 1, and the rear end 6b is provided so as to be able to engage and disengage from a concavo-convex rotating member 7 such as a cam that is pivotally attached to the axle 2a. The switch lever 6 also has a contact piece 8.
is provided, which is configured to open and close between two contacts 10, 10 attached to the support frame 9. These contacts 10, 10 are connected to the motor via cords 11, 11, and can turn on and off the electric circuit of the motor.

On the other hand, 12 is a stopper slidably provided on the wire 5 as an example of means for applying external stress to the switch lever 6. That is, the stopper 12 aligns the upper and lower members 12a and 12b,
The wire 5 is held in the recess 12c formed in each member, and the upper and lower members 12a and 12b are screwed together with the screw 1.
By tightening the wires 3 and 13, the degree of tightening of the wire 5 can be changed in the recess 12c, and the force required to slide the stopper 12 along the wire 5 can be varied.

Therefore, according to the above structure, first, the wire 5 is stretched over the road surface 14 as shown in FIG. Reference numerals 18 and 18 are struts that stretch both ends of the wire 5. Then, a wire guide 4 provided on the traveling vehicle 1
The wire 5 is loosely inserted into the hole 4a. Then, the vehicle 1 is placed at the goal point 15. At this time, the switch lever 6 is pulled forward, and the contact piece 8 is connected to the contact point 1.
0 and 10 are closed. Note that the main switch (not shown) is open at this time. Further, the rear end 6b of the switch lever 6 is separated from the uneven rotating member 7 provided on the axle 2a.

This completes the setup, and as shown in FIG. 1, the vehicles 1, which are arranged in parallel, are slightly lifted to lift the wheels 2 slightly off the road surface, and the main switch is turned on. Next, when the wheels 2 land on the ground at the "start" signal, the vehicles 1 start all at once, and since they are guided by the wire 5, each vehicle 1 maintains a predetermined speed even when traveling at a high speed. You won't go off course and you won't hit other cars.

And stopper 12 placed at the goal point.
When the front end 6a of the switch lever 6 protruding forward of the vehicle 1 comes into contact with the front end 6a of the switch lever 6, the switch lever 6 moves rearward and the contact piece 8 contacts the contacts 10, 10.
The rear end 6b of the switch lever 6 engages with the uneven rotating member 7 provided on the axle 2a to stop the rotation of the wheel 2. Moreover, at this time, if the stopper 12 is attached to the wire 5 so that it can slide freely with almost no resistance, the traveling vehicle 1 will be inertia with the previous momentum.
It skids 50-60cm and stops. Further, by appropriately tightening the screw 13 so that the stopper 12 slides against the wire 5 with some resistance, the slip distance can be arbitrarily adjusted to further reduce the slip distance.

Note that the structure of the switch lever 6 is arbitrary, and basically it may be configured such that it can be slid by external stress caused by hitting the stopper 12, etc., and that the contact points 10, 1 are
It is sufficient to open and close 0 and stop the rotation of the axle shaft 2a. Therefore, the switch lever 6 is connected to the axle 2a.
As shown in FIG. 5, for example, a rubber disc-shaped member 17 is attached to the axle 2a, and a slope 6c is provided on the upper surface of the rear end of the switch lever 6, as shown in FIG. When the switch lever 6 moves backward, the slope 6c may come into pressure contact with the circumferential surface of the disc-shaped member, thereby applying a brake to the wheel 2a. In that case, switch lever 6
A spring force is applied rearward to the switch lever 6, and the switch lever 6 is moved forward against the spring force.
It is preferable to provide the switch lever 6 in such a way that the switch lever 6 can be held and released from this state when an external force is applied to the switch lever 6.

Effects of the invention As described above, according to the invention, firstly, it is possible to run cars directly on the road surface and compete by stretching wires on the concrete road surface, etc., without using a running road base as in the past. Even if you drive at breakneck speed, you'll be guided by wires so you won't deviate from the designated course. Second, at the goal point, an external force acts on the switch lever and the switch lever operates, cutting off the driving source of the vehicle, so it does not force the vehicle to run from then on, and at the same time, the wheels stop rotating, so the vehicle is driven by inertia. It slips and stops when it loses momentum. In other words, the speed of the running car gradually slows down in a stepless manner until it stops, so you can stop the running car by stopping it at the goal point, such as by catching it with your hand or hitting it against a sponge or cushion. This has the effect that no impact is applied to the car and it will not be damaged by twisting.
