Abstract

PURPOSE: To freely change the direction of a car body even at traveling time and stopping time, and enable travel in all directions by holding levers and a column by sliding spherical surface bearings in a disk so as to be freely movable in the horizontal direction. CONSTITUTION: An output shaft is rotated by transmitting torque of motive power 6 to the whole disk 3 through chains 14 and 15 and sprockets 10, 11, 12 and 13. Wheels 8 having a caster having a wheel on the side are installed on the disk 3. A ring whose inside surface contacts with the wheel is installed on the disk 3. The disk 3 is installed on a chassis 2 so that levers 4 and 5 and a column 22 can be freely moved by spherical surface bearings 18, 19, 20, 21, 27 and 28. Cam-followers attached to the side of the wheels 8 are installed so as to enter a groove of the ring having a groove. A disk 7 is formed as a sprocket, and an output shaft of the motive power 6 is put out under the chassis 2, and is rotated by directly driving the disk 7 by the chains.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is capable of traveling in all directions without changing the orientation of the vehicle body, and at the same time allows the vehicle body to be oriented freely while traveling or stopped. It relates to a traveling device that can change the. 2. Description of the Related Art In the prior art, since only one traveling device was attached to the vehicle body, the direction of the vehicle body could not be freely changed. It is possible to travel in all directions and at the same time to freely change the direction of the vehicle body while running or at a stop. As shown in FIG. 6, the wheels of each traveling device are made into wheels (8) with casters so that the wheels can be turned freely, as shown in FIG. The inner surface of the ring (23) to the wheel (2
By pressing it against 4), the direction of (8) (A, B,
By changing (C, D) to (A ', B', C ', D') and rotating (7) in the direction of (E) in this state,
It is intended to drive in the direction of (F). This is possible because the plurality of traveling devices prevent the reverse rotation of the entire vehicle body due to the reaction due to the rotation of (7). Therefore, the traveling direction can be changed by changing the pressing direction of (23). (2
As shown in FIG. 5, 3) is attached and fixed to the disk (3), and the traveling direction of all traveling devices can be controlled by moving (3) with levers (4, 5). This allows the entire vehicle body to travel in all directions. Therefore, it is possible to rotate the vehicle body on the spot by rotating (3). By moving the disk (3) to which the ring (23) is attached by the levers (4, 5), the direction of the wheels (8) of the traveling device is changed so that the traveling direction and the direction of the vehicle body are changed. By changing the angle of tilting (4,5) at the same time as changing, the running speed and running direction can be changed. Embodiment (a) The rotational force of the power (6) is applied to the chain (14, 1).
5) and via the sprockets (10, 11, 12, 13), it is transmitted to the entire disk (3) and rotated. (B) A wheel (8) with casters having wheels (24) on its side is attached to the disk (3). (C) A ring (23) whose inner surface is in contact with the wheel (24) is attached to the disc (3). (D) The disk (3) is mounted on the chassis (2), the levers (4, 5) and the support (22) are mounted on spherical bearings (18, 1).
9, 20, 21, 27, 28) so that it can be moved freely. (E) Wheel (8) in the groove of the ring (29) with grooves
Install so that the cam follower (30) attached to the side of can be inserted. (F) The disk (7) is used as a sprocket, and the power (6)
Put the output shaft of under under the chassis (2) and directly drive (7) with a chain to rotate. The present invention has the above-mentioned structure. When using the present invention, the user rides on the chassis (1) and operates the levers (4, 5) with both hands. When both levers are tilted in the same direction, the car body runs in the direction in which the levers were tilted. When the lever (4) is kept vertical and the lever (5) is tilted in the circumferential direction, the disk (3) rotates, each wheel runs in the circumferential direction, and the vehicle body rotates on the spot. If the levers (4, 5) are tilted and the levers (5) are also tilted in the circumferential direction at the same time, the vehicle body runs in a curve. In this way, by operating the two levers, it is possible to travel in all directions and at the same time change the direction of the vehicle body.
