Description

[Detailed description of the invention] (Field of industrial application) This invention is a four-wheeled vehicle that allows the user to freely select between arc-shaped travel, straight-line travel, etc. by arbitrarily replacing the front, rear, left, and right tires. It is related to car toys.

(Prior Art) Conventionally, a four-wheeled vehicle was developed in 1989-88991, in which the user was able to freely select between traveling in an arc, traveling in a straight line, etc. by changing the front, rear, left, and right tires. No. 61-65994 and the like.

(Problem to be solved by the invention) However, in the former case, a tube part integrated with the large wheel is fitted onto the outer periphery of a small wheel attached to a toy car, and the same wheel is turned into a toy car. Since it is designed to be installed, if the wheels already installed on the toy car are worn out due to use and their diameter becomes noticeable, the inner diameter of the cylinder part will not match and it will be necessary to install a larger diameter wheel. The latter is a type in which a small wheel is attached to a wheel, and a large wheel is attached to this wheel via an adapter, and the center of each wheel and adapter has a tire detachment at the center of its outer periphery. A locking part is formed for prevention, and the structure is such that the recesses provided on the inside of each tire are fitted into these, so when fitting each tire to the wheel and adapter, the inside of these tires must be turned outward. There were problems such as the need to turn the paper over and over again, which was quite troublesome.

(Means for Solving the Problems) The present invention provides wheels 3, 3', 4 of the same diameter at both left and right outer ends of the front axle 1 and at both left and right outer ends of the rear axle 2.
4' is fixed in a non-rotatable manner and the main body 5
and a pair of small-diameter tires 7, 7' having an inner diameter hole 6 configured to be fitted to the outer periphery of the wheels 3, 3', 4, 4' in a non-rotatable but removable state.
The present invention aims to eliminate such defects by providing a four-wheeled vehicle toy characterized by having a pair of large-diameter tires 9, 9' having a similar inner diameter hole 6.

(Embodiment) The first embodiment shown in FIGS. 1 to 11 is a traveling vehicle equipped with a rear axle 2 driven by a built-in spring device 10 and a driven front axle 1.
Hexagonal front, rear, left and right wheels 3, 3', 4, 4' of the same size are fixed to the left and right outer ends of the front axle 1 and the rear axle 2 in a non-rotatable manner, and separately, The inner diameter hole 6 is made of a hard synthetic resin material with elasticity.
A circular dish-shaped body 11 exhibiting a hexagonal shape of the same size as 4' is constructed, and two pairs of deep cuts 12, 12' are provided at the opening edge of this dish-shaped body 11.
12' is the elastic leg 13, 13', and the elastic leg 1
A pair of small-diameter tires 7, 7' are provided with an inward hook 14 at the tip of the disc-shaped body 11, and a small-diameter rubber ring 15 is fitted over the outer periphery of the dish-shaped body 11.
In addition, a pair of large diameter tires 9, 9' each having an inner diameter hole 6 are constructed in the same manner as the small diameter tires 7, 7', and the inner diameter hole 6 of the small diameter tires 7, 7' is arranged on the front left side.
The hook 14 of the plate-shaped body 11 of the small-diameter tire 7, 7' is removably engaged with the inner surface edge of the wheel 3, 3' by fitting it into the front right wheel 3, 3', and the large The diameter tires 9, 9' are also small diameter tires 7,
7', it is removably fitted to the rear left and rear right wheels 4, 4'.

In addition, Fig. 7 shows large diameter tires 9, 9' on the front left and front right wheels 3, 3', and rear left and rear right wheels 4,
4', small diameter tires 7, 7', and in Figure 8, front left and rear left wheels 3, 4 and large diameter tires 9, 9', front right and rear left wheels 3, 4, respectively.
Small diameter tires 7, 7' are installed on the rear right wheels 3', 4'.
Figure 9 shows large diameter tires 9, 9' on the front left and rear left wheels 3, 4, small diameter tires 7, 7' on the front right and rear right wheels 3', 4', and Figure 10 shows front left and rear tires. Small diameter tires 7, 7' are mounted on the right wheels 3, 4', large diameter tires 9, 9' are mounted on the front right and rear left wheels 3', 4, and the first
Figure 1 shows the state in which large diameter tires 9, 9' are fitted to the front left and rear right wheels 3' and 4, and small diameter tires 7 and 7' are fitted to the front right and rear left wheels 3 and 4', respectively. .

The second embodiment shown in FIGS. 12 to 14 has a configuration in which the dish-shaped body 11 is not used, and is made of rubber and is removably fitted to the wheels 3, 3', 4, and 4' by the contraction force of the inner diameter hole 17. At the same time, a rubber ring 19 is fitted into a groove 19' provided on the outer periphery of the tire 18 to form large-diameter tires 9, 9', and small-diameter tires 7, 7' are formed via the rubber ring 19, respectively. Equal-sized tires 9, 9' and small-diameter tires 7, 7' are fitted onto the wheels 3, 3', 4, 4' of the traveling car toy and main body 5 constructed in the same manner as in the first embodiment. It is something.

The third embodiment shown in FIGS. 15 to 17 is the second embodiment.
It has almost the same configuration as the embodiment, and the tires 7, 7',
The difference is that the parts 9, 9' and the rubber ring 19 are connected by a bendable thin part 20.

(Operations and Effects of the Invention) Since the present invention has the above-described configuration, the large diameter tires 9, 9' and the small diameter tires 7, 7' are attached to the front and rear axles 1, 2 in the arrangement shown in FIG. If installed in the arrangement shown in Figure 7, it will run normally, if installed in the arrangement shown in Figure 7, it will run in a wheelie, if installed in the arrangement shown in Figure 8, it will run counterclockwise, and if it is installed in the arrangement shown in Figure 9, it will run in a counterclockwise direction. If the vehicle is installed in the arrangement shown in Figures 10 and 11, it will be possible to travel in a clockwise direction, and it is of course very interesting to be able to travel in a clockwise direction. A running device or main body 5 has wheels 3, 3', 4, 4' of the same diameter fixed non-rotatably to both left and right outer ends of the rear axle 2 and both left and right outer ends of the rear axle 2, and wheels 3, 3', 4, A pair of small-diameter tires 7, 7' having an inner diameter hole 6 configured to be fitted to the outer circumference of the tire 4' in a non-rotatable but removable state, and a pair of large-diameter tires having a similar inner diameter hole 6. 9, 9', each tire 7, 7', has a smaller diameter and a larger diameter than the known tire.
9 and 9' can be easily and reliably replaced, and the present invention has the effect of fully solving the above-mentioned problems.
