ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a walking apparatus that is used for a toy such as an insect toy.
2. Description of the Related Art
There is known a conventional insect toy that is swingably provided with a front leg stick, a middle leg stick and a rear leg stick under its body, which are swung to slidingly advance the body on a walking surface as described in Japanese Examined Utility Model Publication No. Sho 62-26144.
The conventional insect toy has a problem of lacking realism because it is swingably provided with a front leg stick, a middle leg stick and a rear leg stick under its body, whereas an actual insect has legs extending from its body. In addition, there is a problem that a conventional insect toy can not overcome even a small gap and stops because it slidingly proceeds. Hence, its movement is entirely different from that of an actual insect that can overcome and proceed through such a gap.
SUMMARY OF THE INVENTION
The present invention has been made in view of the above-described drawbacks, and therefore it is an object of the present invention to provide a walking apparatus having a shape similar to that of an actual insect and capable of making movements similar to those of an actual insect.
In order to attain the above-described object, a walking apparatus according to a first aspect of the present invention is comprised of: an apparatus body provided with a power source; at least two rotating members provided on each of the left and the right sides of the apparatus body; a through hole formed in the rotating member; the through hole being provided obliquely with respect to a rotational axial line of the rotating member, and being formed to connect an inner opening and an outer opening, the inner opening being formed toward the center of the inner side surface of the rotating member and the outer opening being formed toward the circumference of the outer side surface of the rotating member; a leg portion rotatably and slidably mounted to the through hole of the rotating member; a guiding groove for slidably guiding a rear end part of the leg portion protruding from the inner opening of the rotating member formed in the apparatus body thereby preventing the leg portion from turning on its axis; and the rotating member that rotates by the power source.
In order to attain the above-described object, according to a second aspect of the present invention, in a walking apparatus of the first aspect of the present invention, the guiding groove is formed substantially parallel with the rotational axial line of the rotating member, and the leg portion includes a rear part protruding from the inner opening of the rotating member to be bent and a rear end part guided slidably into the guiding groove.
In order to attain the above-described object, according to a third aspect of the present invention, in a walking apparatus of the first aspect of the present invention, the apparatus body includes a bottom wall and side walls provided in the left and the right of the bottom wall, each of the left and the right side walls includes at least two rotating members, and the guiding groove is formed in the bottom wall.
A walking apparatus according to a fourth aspect of the present invention has two power sources described above, one of which rotates the rotating member in one of the side walls and the other power source rotates the rotating member in the other side wall. A walking apparatus according to a fifth aspect of the present invention has a gear wheel as a rotating member.
