Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a wheel coupling device for a toy car.

BACKGROUND ART Conventionally, toy cars have been known in which front, rear, left and right wheels are attached to an axle provided on the car body, and a driver's cab and cargo platform are attached to complete the toy car, or the toy car is disassembled into each part.

Further, as a variation thereof, for example, Japanese Utility Model Application No. 183295/1983 has been proposed in which a plurality of vehicle bodies are connected. However, all of these proposals merely connect multiple vehicle bodies via connectors;
The connection is lacking in surprises.

Problems that the invention aims to solve Conventionally, toys that are assembled and disassembled so that each part can be completed and experienced, have a roughly fixed procedure for assembling and disassembling, and there is no variation in the order, so it is difficult to play. It had a limited framework and lacked creativity.

This idea dramatically expands the range of interesting movements by providing connectivity to the wheels, and creates unexpected connections between toy bodies and wheels.
The aim is to further enrich the world of play with toy cars.

Means for Solving the Problem A toy car is provided with a joint shaft at the outer end of each axle, and a wheel is provided with a bearing hole that allows the joint shafts to be connected in parallel from both sides. has a rotation prevention protrusion and a ring groove for prevention in the bearing hole, and is formed around the circumference so that a tire can be fitted therein, and the joint shaft has a protrusion that engages with the rotation prevention protrusion of the wheel. The present invention provides a wheel coupling device for a toy automobile, which is provided with a protruding ring that engages with a retaining annular groove.

Function According to the present proposal, the toy car can run easily on a flat road by connecting ordinary wheels to the drive axle as shown by the solid line in Figure 12, and also as shown by the temporary line. For example, by combining off-road wheels, a single vehicle can drive dynamically over uneven roads.

Next, since a wheel can be connected to an axle on both sides by the wheel, for example, if the driving axles of two car bodies are connected to one wheel, as shown in Fig. 13, the driving force can be increased. In addition, as shown in Fig. 14, wheels of the same diameter or different diameters can be freely joined laterally using an intermediate joint shaft, as shown in Fig. 14. With multiple wheels,
It is possible to obtain running performance close to that of endless tracked wheels.

Embodiment Hereinafter, this invention will be explained with reference to an embodiment shown in the drawings. Reference numeral 1 denotes a wheel of the first embodiment, which has bosses 4, 4 equipped with bearing holes 3, 3 to which the axle 2 can be jointed on both sides. It consists of a wheel 5 protruding to both sides and a tire 6 fitted around it, and the bearing hole 3 of the boss 4 has a rotation prevention protrusion 7 on the innermost inner diameter surface and an annular groove 8 for preventing slippage. They are respectively provided on the inner diameter surface on the entrance side and are engaged with a tip protrusion 10 at the tip of a joint shaft 9 fixed to the axle 2 and a protrusion ring 11 protruding around the inner end.

12 is a wheel of the second embodiment, in which a boss 4a on one side of the wheel projects outward from the side surface of the wheel;
When the wheels are jointed to the toy car body, the sides of the wheels do not touch the car body. The bearing hole 3 on both sides thereof is provided with a rotation prevention protrusion 7 and a retaining annular groove 8 that fit and fit into the joint shaft 9 and engage with the protrusion 10 and the protrusion ring 11. Of course.

Reference numeral 13 denotes an intermediate joint shaft, which is formed by driving the axle joint shaft 9 into the core shaft 14 from both sides with the attachment/detachment support plate 15 in the middle. It is okay to do so.

Reference numeral 16 denotes a toy car, which has driving axles 2a and 2b arranged at the front and rear of the lower part of the car body 17, and when a switch 19 arranged on the upper surface of the body 18 is pressed, a battery housed inside and an internal motor (not shown) are activated. When the power supply circuit is closed, the motor rotates, and the rotation is reduced at an appropriate reduction ratio and transmitted to the drive axles 2a, 2a. Next, when switch 19 is pressed, the power supply circuit opens and the motor stops. This is set up so that it operates repeatedly. A joint shaft 9 is attached to the drive axles 2a, 2a.
have been entered respectively.

The connection between the axles 2, 2a and the wheels 1, 12 is not limited to the structure shown in the illustrated embodiment, and may include the locking structure shown, as well as, although not shown,
For example, it may be a male threaded shaft and a female threaded hole.

In the above embodiment, the wheel 5 and the rubber tire 6 are constructed of two parts, but of course they may be formed integrally from a single piece of material, and the boss 4 does not particularly need to protrude from the side.

Effects of the invention This invention is as described above, so the wheels can be replaced with respect to the axle, and it can be used to suit the road surface, and although it is a single car body, it can be changed like a different type of running toy. It's something you can play with. In particular, since the wheels can be connected laterally using an intermediate joint shaft, the play is active and can be used in various ways, unlike the conventional method of installing or disassembling one type of wheel in the assembly order. They can be combined to create endless tracked or even more off-road fun. Furthermore, since multiple vehicle bodies can be connected laterally via the wheels, play that has not been possible before is possible.

Therefore, it has the effect of improving the play range of conventional toy cars while providing a sense of reality.
