Description

[Detailed description of the invention] The present invention relates to a device for changing the running mode of a running rigid tool.
In particular, by connecting the members to the wheels of the running gear, the running mode can be changed.

With conventional running devices, the only way to change the running mode is to change the speed, and this is done by changing the gear ratio or the rotational speed of the motor, which results in a complicated structure and high cost. It was hot. In addition, there is no vehicle that allows changing the driving direction or driving state or other driving aspects easily and inexpensively.

This invention achieves
It is an object of the present invention to provide a device for changing the running mode of a running rigid tool which can easily and inexpensively change the running mode to any desired running mode.

The present invention will be described below with reference to embodiments shown in the drawings.

1 to 3 show a first embodiment.
Reference numerals 1 and 1' denote running parts, and the front wheels 2 and 2' and the rear wheels 3 and 3' of the running parts 1 and 1' are equipped with the parts shown in FIG. As shown, an annular groove 10 that opens outward is formed in the wheel. 5 is a traveling mode changing member which is another element constituting the main part of the present invention, and has a cylindrical part 4 that fits into the annular groove 10,
It has an annular groove 6 that opens on the outer periphery. The changing member 5 having the recessed groove 6 is used to obtain a running mode in which the two front and rear running fixtures are coupled and run using the connecting member 9.

That is, the connecting member 9, as shown in FIG.
Equipped with a shaft hole 8 having a notch 7 at both ends,
By removably fitting the changing member 5 into each shaft hole at the groove 6, the changing members 5 of the front and rear traveling rigid parts can be rotatably connected by the connecting member 9.

With this configuration, as shown in Figure 1,
The cylindrical part 4 of the changing member 5 is pushed into the annular groove 10 of the rear wheel 3 of the front running rigid member 1 and the front wheel 2' of the rear traveling rigid member 1' to connect them. The connecting member 9 is mounted by loosely fitting the shaft hole 8 into the shaft hole 6. In this way, the two front and rear running rigid parts 1, 1' are changed to the changing member 5,
5' and the connecting member 9, the vehicle can travel in a connected state.

FIG. 4 shows a changing member 11 according to a second embodiment of the present invention. This changing member has a cylindrical portion 4 that is press-fitted into an annular groove 10 of the wheel and is provided with a deformable cam that at least partially protrudes outside the ground contact surface of the wheel 2 or 3. Therefore, when this modification member is fitted into the annular groove of the wheel and the wheel is driven, it will only travel smoothly in a straight line without the modification member attached, but it will sway up and down due to the irregularities of the deformation cam. However, it is possible to realize a driving mode in which speed change is made in a straight line, meandering, or rotating.

FIG. 5 shows a third embodiment of the present invention.

In this embodiment, the changing member 13 is provided with a pair of discs 12 on the outer periphery of a cylindrical part to be fitted into the annular groove 10 of the wheel, and a groove is formed between them, so that the change member 13 can be fitted with a rail, for example. It is possible to use a running mode in which the grooves are used to run, such as fitting them together and running them along a rail.

As described above, according to this invention, a wheel having an annular groove 10 opening outward, a cylindrical portion removably fitted into the annular groove, and parts 6, 11, 12 for changing the running mode are provided. By simply attaching the changing member to the wheels, you can easily change the running mode of the travel fixture from simple smooth linear running to coupled running, vertical vibration linear running, vertical vibration meandering running, or rotational running. , it can be enjoyed by changing to other running modes such as rail following running, and the structure is simple, so it is inexpensive.
