BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will be described in detail below with reference to the drawings. The traveling toy of the present invention comprises a main body (1) of a toy, and two rotations which are positioned on both sides of the main body (1) and are rotatably supported at one end and rotatable relative to the main body. It is equipped with an arm (2). Body
The traveling means (3), (1) and the rotating arm (2) respectively
(4) is attached, these traveling means (3),
(4) are connected so that they both run in the same direction. Body
The (1) and the rotating arm (2) are rotatably supported at their one ends, and one of them is rotatable relative to the other by 360 °. In the main body (1), the traveling means (3),
A first motor (5) for applying a driving force to (4) and a second motor (6) for rotating the rotating shafts of the main body (1) and the rotating arm (2) are arranged. The first motor (5) is a left and right traveling means.
It is desirable that two (3) and (4) are arranged so that they can be driven independently and that the left and right drive shafts (7) and (8) that are independent of each other can be driven separately. This allows the spin turn of the toy when driving the two motors in opposite directions.

The second motor (6) is fixedly attached to the main body (1) and can drive the rotating shaft (9) directly connected to the rotating arm (2). 2 motor (6)
When the rotary actuator is rotated, the rotary shaft (9) is rotated and the rotary arm (2) directly connected thereto is rotated. As shown in FIGS. 3 and 4, the rotation of the rotation arm (2) appears as a relative rotation movement with respect to the main body (1), and the rotation arm (2) rotates 360 degrees with respect to the main body (1). You can move. Also, a rotating arm
The rotation of the main body (1) is relative to the rotation of the main body (1), and when the rotation of the rotation arm (2) is blocked, the main body (1)
Will rotate with respect to the rotating arm (2). Further, the relative rotational movement between the main body (1) and the rotary arm (2) can be performed simultaneously with the traveling movement of the traveling means (3), (4). As a result, the toy is running and the main body (1) and the rotating arm.
(2) rotates relative to each other, and it is possible to create a very unique running form as shown in FIGS. Furthermore,
As shown in FIGS. 7, 8 and 9, it is possible to climb stairs, climb over steps, and over gaps.

The main body (1) has a vertical cross section of a substantially oval shape and a substantially square shape of a plane, and the inside thereof has the first motor (5),
Second motor (6), these motors (5) (6) and drive shaft (7)
(8) or a power transmission mechanism (10) (11) such as a gear that connects with the rotating shaft (9), and a storage battery (1) that is a power source of the motors (5) (6).
2) Further, a control device (13) for wirelessly controlling the motors (5) and (6) is housed and arranged. In addition, as described above, the main body (1) may rotate relative to the rotary arm (2), and the top surface and the bottom surface may run in reverse so that the main body (1) may travel.
The upper surface and the bottom surface of (1) shall not be formed with a shape projecting outward from the travel locus surface or provided with a projecting structure. However, when limiting the rotation range of the rotating arm (2) and the main body (1) to within 180 °, the main body (1)
It goes without saying that a shape or structure protruding outward may be formed on the upper surface of the.

The rotating arm (2) is formed by connecting one ends of narrow side frames with a rod body (20), which has an oval vertical cross-sectional shape corresponding to the vertical cross-section of the main body (1). It has a U-shaped frame structure and is arranged on both sides of the body (1).
The vertical cross-sectional shapes of the main body (1) and the rotating arm (2) are not limited to such an oval shape, and it goes without saying that they may have a horizontal rectangular shape in cross section or other shapes.

Although the running means (3) and (4) are endless belts in the illustrated embodiment, it goes without saying that they may be wheels. Endless belts, which are traveling means (3), are mounted on both sides of the main body (1), and each endless belt on both sides is individually driven by two independent first motors (5), It is designed to run independently. Therefore, the left and right endless belts can run in the same direction for straight movement, or the left and right endless belts can run in opposite directions for rolling movement. At one end of the body (1), the first
A drive wheel (14) connected to a motor (5) is rotatably supported, and an idler wheel (15) is rotatably supported on the other end of the main body (1) and an endless belt (3) is attached. It is mounted between the drive wheel (14) and the idle wheel (15). Each rotating arm (2) has a traveling means.
The endless belt of (4) is mounted. The endless belt (4) mounted on the rotating arm (2) is connected to the idler wheel (15) pivotally supported on the other end of the main body (1) in the same rotation direction as the connecting wheel (16). ) And an idler wheel (17) pivotally supported at the other end. Idler wheel (15) and pivot arm (2) of body (1)
Since the left and right connecting wheels (16) are directly connected to each other,
The driving force of the motor (5) is transmitted from the endless belt (3) of the main body (1) to the endless belt (4) of the rotating arm (2), and the left and right endless belts (3) and (4) are the same. Will run in the direction.

A rotating shaft (9) connected to the second motor (6)
As shown in FIG. 14, the free wheel (15) of the main body (1) and the connecting wheel (16) of the rotating arm (2) penetrate through the centers in a free state to rotate as shown in FIG. It is fixed to one end of the arm (2) by a rotation preventing means (18) such as a knurl and a square shaft in a rotation preventing state, and is rotated by the driving force of the second motor (6).
When is rotated, the rotating arm (2) is rotated relative to the main body (1) integrally with the rotating shaft. Second motor (6)
A clutch mechanism (19) is interposed between the rotary shaft (9) and the rotary shaft (9) so that the transmission of the driving force is cut off when an unexpected load is applied when the rotary arm (2) is rotated. is there. That is, as shown in FIGS. 15, 17, and 18, the clutch mechanism (19) is composed of two clutch plates that mesh with a large number of chevron teeth, and when an unexpected load is applied, the clutch plates disengage and drive power is transmitted. Be refused. As a result, the main body (1) and the rotating arm
Even when a child's hand is caught between the two when rotating relative to (2), danger can be prevented. First
As shown in FIG. 13, the drive shaft (8) of the motor (5) and the drive wheel (14) are connected by a square shaft or a knurl in a non-rotating state.

19 and 20 show a first motor (5) and a drive shaft.
(7) The transmission mechanism (21) inserted between (8) is shown. The speed change mechanism (21) includes a rocking member (23) rocked by a lever (22) projecting on the upper surface of the main body (1), a speed change gear (24) and a gear wheel (24) moved by the rocking member (23). Transmission gear meshing with the transmission gear (24)
(25) and the transmission gear is moved by the movement of the speed change gear (24).
The gear ratio with (25) is changed to change the speed.
