Abstract

PURPOSE: To easily perform running in various different directions by making a driver move on a main body part, bringing one end of a rotating body into contact with a road surface and making a device run in a prescribed direction. CONSTITUTION: When the driver moves and the body weight of the driver is concentrated to the side of a plate body 36b, a guide bar 42b engaged to the plate body 36b is displaced in a vertical lower direction against the repulsive force of a spring 44 and a caster 50b held to the plate body 36b pressurizes the upper surface part of a disk 54 for constituting the rotating body 22 in the vertical lower direction. Thus, since the main body part 18 and the rotating body 22 are integrally tilted, the lower end 56a of a bristle part 56 generates frictional force with a traveling surface 12 since the end part of the side of the guide bar 42b is brought into contact with the running surface 12 and the rotating body 22 is rotated, this running device starts running. Thus, the driver easily makes the running device travel in a desired direction just by moving to an optional position.

Casters 50a to 50f are rotatably supported on f. The casters 50a to 50f move on the rotating body 22, and have their respective axes in a direction perpendicular to the direction of rotation of the rotating body 22.

Next, a rotary shaft 51 is rotatably supported on the lower surface of the support body 40 so as to be oriented in the vertical direction.
A large-diameter sprocket 52 and a rotating body 22 are coaxially attached to the rotor. The rotating body 22 is a flocked body that substantially constitutes a brush or the like, and includes a disc 54 on which the casters 50a to 50f roll, and a flocked body installed on the lower surface of this disc 54 and extending vertically downward. It consists of a section 56. In this case, as described above, the main body 18 is pressed in a direction away from the running surface 12 by the elastic force of the springs 44 mounted on the guide bars 42a to 42f, and the rotating body 22
The lower end 56a of the flocked portion 56 constituting the bristle part 56 is spaced apart from the running surface 12 by a predetermined distance (see FIG. 2).

Furthermore, one end of a chain 58 is engaged with the sprocket 52, and the other end of the chain 58 is connected to a gear box 60 fixed to a square rod 32a of the outer frame 32.
It is suspended on a small diameter sprocket 62. The gear box 60 is provided with a large diameter sprocket 64 having an axis perpendicular to the axis of the sprocket 62,
A chain 66 suspended from this sprocket 64 is engaged with the drive section 24 side.

The drive unit 24 includes a bent frame member 68, and mutually parallel pieces 70a, 70a of the frame member 68.
are swingably supported in the vertical direction via vias 14a, 74b, respectively, on pairs of mounting plates 72a, 72a and 72b, 72b, which are attached to the negative square bar 32a of the outer frame 32. The other mutually parallel pieces 70 of the frame member 68

At this time, the gripping bar 86 may be provided with a switch or the like for driving and stopping the rotational drive source 78.

The traveling device according to this embodiment is basically constructed as described above, and its operation and effects will be explained next.

First, the driver first looks at the cover 82 attached to the main body 18.
The gripping bar 86 is gripped by being located approximately at the upper center. At that time, since the driver is located approximately at the center of the main body 18,
The main body portion 18 is slightly lowered against the elastic force of each spring 44, and the flocked portion 56 of the rotary body 22 is moved toward the running surface 12.
never come into contact with.

Next, the rotary drive source 7 is turned on by operating a switch (not shown) or the like.
8, the rotational drive shaft 78 of this rotational drive source 78
a rotates in a predetermined direction, and a small-diameter sprocket 80 pivotally attached to this rotary drive shaft 78a rotates. Further, a relatively large diameter sprocket 64 rotates via the chain 66, and the rotation of this sprocket 64 is transmitted to a small diameter sprocket 62 provided in the gear box 60. Therefore, the large-diameter sprocket 52 rotates at a considerably reduced speed via the chain 58 that engages with the sprocket 62, and the rotating shaft 51 that connects the sprocket 52 and the rotating body 22 rotate together at a low speed. It comes to that.

Therefore, when the driver moves to the position shown in (1) in FIG. 3, the weight of the driver is substantially concentrated on the plate body 36b side, as shown in FIG. 1. Therefore, as shown in FIG. 4, the guide bar 42b that is attached to the plate 36b is displaced vertically downward against the elastic force of the spring 44, and is held by the plate 36b. caster 50
b presses the upper surface of the disk 54 constituting the rotating body 22 in a vertically downward direction. Therefore, the main body 18 and the rotating body 22 tilt together, and the lower end 56a of the flocked part 56 contacts the end on the guide bar 42b side with the running surface 12 (see the two-dot chain line in FIG. 4). .

As a result, as shown in FIG. 3, since the lower end 56a of the flocked portion 56 comes into contact with the running surface 12 at the position shown in (I), a frictional force is generated between the running surface 12 and the rotating body. 22 rotates in the direction shown by the dashed arrow, the traveling device 10 starts traveling in the direction of arrow A.

Furthermore, when the driver moves to the position (II) in FIG. It tilts in the opposite direction to the above.

Therefore, the lower end 56 of the flocked portion 56 corresponding to the plate body 36e
a comes into contact with the running surface 12, and the running device 10 has the following points in FIG.
It will move in the direction of arrow B.

Furthermore, when the driver moves to the position (III) or (IV) in FIG.
The traveling device 10 moves in the direction of arrow C (
(■) position) or in the direction of the arrow ((■) position).

Therefore, for example, if the driver moves to position (V),
It is possible to run in the direction of arrow E while turning at a predetermined curvature.

In this manner, in this embodiment, the driver can move the traveling device 10 by simply moving to an arbitrary position on the cover 82.
It becomes possible to easily run the vehicle in a desired direction. Furthermore, the wheels 14a to 14f are mounted on the base frame 16, and a large diameter wheel 76 is provided on the main body 18 via a frame member 68. Therefore, even if the rotating body 22 rotates as shown by the broken line arrow in FIG. 3, the traveling device 10 itself does not rotate unnecessarily. as a result,
The effect is that running stability is improved and good riding comfort can be ensured.

Further, when the rotating body 22 is rotated under the driving action of the rotational drive source 78, the casters 50a to 50f provided on the main body 18 contact the disk 54 constituting the rotating body 22 and roll. . Therefore, the rotation of the rotating body 22 is
8, and the driver positioned on the cover 82 attached to the main body 18 can maintain a stable riding posture.

Further, instead of directly mounting the rotary drive source 78 on the main body 18, the rotary drive source 78 is held by large-diameter wheels 76 via a frame member 68 that swingably engages with the main body 18. ing. Therefore, the weight of the rotational drive source 78 does not directly act on the main body 18, which is advantageous in that the main body 18 can be made lighter, and the traveling device 10 can be easily manufactured in a smaller size. can be mentioned.

[Effects of the Invention] As described above, according to the present invention, the main body is displaceably mounted on a base frame provided with a plurality of wheels via an elastic body, and the main body is mounted substantially orthogonally to the running surface. It supports a rotating body that has an axis that rotates under the driving action of a rotational drive source. Therefore, when the driver simply moves the main body to a desired position, the main body and the rotating body tilt, and a part of the rotating body comes into contact with the running surface, moving the running device in the desired direction. It can be made to run. Moreover, when the rotating body rotates, the main body itself does not rotate (this has the effect of ensuring a stable riding posture for the driver positioned on the main body).

Furthermore, the rotational drive source is disposed separately from the main body via a frame member that is swingable with respect to the main body, and
Wheels are provided on this frame member to hold the rotational drive source. Therefore, it is possible to reduce the weight and size of the main body portion all at once. Moreover, there is an advantage that the traveling device can be effectively driven in a desired direction via the wheels provided on the frame member.

Although the present invention has been described above with reference to preferred embodiments, the present invention is not limited to these embodiments.
For example, a switch or the like for driving a rotary drive source is provided on a rod erected on the main body, and the gist of the present invention is that this rotary drive source can be remotely controlled from a position separated from the traveling device. Of course, various improvements and changes in design are possible without departing from the above.
