Description

[Detailed description of the invention] Industrial field of application This invention relates to a flywheel toy that can be tilted in various directions using the rotational inertia of the flywheel housed inside, and particularly relates to the This invention relates to a flywheel toy that can run by grounding the outer peripheral edge of the lower end of a spindle to which a flywheel is attached.

BACKGROUND ART Conventionally, Utility Model Publication No. 37-21937 and Utility Model Publication No. 44-20283 have been disclosed as devices which are made to stand upright by a flywheel rotating at high speed and run by a rotating shaft to which the flywheel is attached. There is. Also,
In these conventional techniques, auxiliary legs are attached near the flywheel shaft that is in contact with the ground in order to maintain the upright state.

Problems to be Solved by the Invention The above-mentioned conventional technology has excellent features as a mechanism for standing the toy object upright and maintaining this state. A flywheel that rotates at high speed originally has the functional property of stopping at a certain position and maintaining an upright state, but the outer periphery of the rotating shaft to which the flywheel is attached allows the toy to be rotated vertically and horizontally. It was inappropriate as a drive mechanism for running the vehicle.

Means for Solving the Problems The present invention has been made to solve the problems in the above-mentioned conventional technology, and uses a spindle on which a flywheel is attached along the axial direction of a main body with a certain external shape. The lower end of the support shaft projects toward the lower side of the main body, and an opening is provided in the front-back direction of the center of the main body, and a part of the outer circumferential surface of the flywheel is inserted through the opening. The lower part of the main body is provided with auxiliary legs that are long on one side and short on the other side in order to allow the main body to stand tilted and keep the lower end peripheral edge of the support shaft in contact with the ground. be.

Function When a flywheel toy is placed on the floor by applying rotational force to the flywheel, the main body will stand at a slight incline, and the outer periphery of the rotating shaft of the flywheel that is in contact with the floor will The vehicle then travels in a predetermined direction. Furthermore, when the main body is laid down and placed on the floor, the outer circumferential surface of the flywheel exposed at the opening of the main body comes into contact with the ground, allowing the machine to travel in a fixed direction.

Embodiments The figures show various modes in which a body 1 shaped like a robot doll is rotated on a smooth floor surface 2. In each figure, the doll body 3 has a circularly swollen outer periphery. The main body 3 has a concave portion (not shown) which is open in the front and rear directions at the center thereof, penetrated by an opening 4 that expands in an arc shape, and has a downward opening on both left and right sides of the body portion 3 (not shown). ), and left and right arm members 5, 5 are provided in each recessed portion, the proximal ends of which are supported and connected.

Further, a protrusion 7 is formed at the center tip of the doll head 6.

Furthermore, the doll legs 8 are half-cut spherical bodies 8a, 8b.
are arranged side by side, with a boss 9 protruding from the center, and left and right spherical bodies 8a, 8b.
rear auxiliary legs 10a protruding downward from the bottom;
10b is provided, and further the rear auxiliary leg 10
Front auxiliary legs 11a and 11b, which are shorter than the rear auxiliary legs 10a and 10b, protrude from the inside fronts of the left and right spherical bodies 8a and 8b, facing the spherical bodies 8a and 10b.

The doll body formed as described above has its center of gravity slightly displaced backward from the axis, and the support shaft 12 is located slightly behind the axis and along the axis.
is inserted, the upper end of the support shaft 12 is supported within the doll head 6, the lower end is supported by the boss 9, and the lower end projects from the boss 9.

In this way, the bottom of the doll leg 8 includes the lower end of the support shaft 12, the rear auxiliary legs 10a, 10b provided on each leg 8, and the auxiliary legs 11a, 1.
1b protrudes, so that when the doll body is normally erected on the floor, the main body 1 is supported by these protrusions and can maintain its erect posture. However, the protruding length of each auxiliary leg is different, and the lower end of the support shaft 12 is different from the plane connecting the tips of the longest rear auxiliary legs 10a, 10b and the shortest front auxiliary legs 11a, 11b. It protrudes downward and is shorter than the rear auxiliary legs 10a and 10b.

A support shaft 12 is disposed inside the main body 1 formed as described above along the axis of the main body 1, and a flywheel 13 is axially attached to the support shaft 12, which passes through the opening 4 formed in the main body 1 and is built into the trunk 3 with a part of it exposed from the opening 4 or without being exposed.
A pinion 14 is coaxially attached to the underside of the main body 1, and a through hole 15 is formed on one side of the pinion 14 in the front-rear direction of the main body 1.
As shown in the figure, a rack belt 16 having a rack 17 engraved on one side is inserted, the rack 17 engraved on the rack belt 16 is meshed with the pinion 14, and the rack belt 16 is pulled in the direction of the handle 16a, whereby the flywheel 13 can be rotated in the pulling direction of the rack belt 16.

Furthermore, a rotating member 1 made of an elastic member is loosely fitted onto the support shaft 12 and is mounted on the upper surface of the flywheel 13.
8 is provided, a portion of which protrudes from the opposing position of the outer peripheral surface of the rotating member 18, and is bent downward to cover the outer peripheral surface of the flywheel 13 and follow the flywheel 13. Protrusions 19, 19 that rotate and project outside the body 3 are formed.

Next, the operation of the flywheel toy will be explained.

First, to operate the flywheel toy, the rack belt 16 inserted through the through hole 15 is pulled toward the user to rotate the flywheel 13 integrated with the pinion 14.

When this is placed on the floor 2 in a normal standing posture, a restoring force acts on the rotating top, which is made up of the spindle 12 and the flywheel 13, to try to stand upright. Main body 1 has rear auxiliary legs 10
It is supported at three points on the floor 2 by a, 10b and the outer peripheral edge of the lower end of the support shaft 12. Since the lower end of the support shaft 12 is formed shorter than the tips of the rear auxiliary legs 10a, 10b, the main body 1 stands on the floor 2 in a slightly forward-leaning posture. At this time, the front auxiliary legs 11a and 11b are separated so as to float above the floor surface 2. Therefore, the outer peripheral edge of the lower end of the spindle 12 comes into contact with the floor surface 2, and the spindle 12, which rotates at high speed, functions as a driving wheel by bringing the outer peripheral edge of its lower end into contact with the floor surface 2. , the main body 1 runs linearly on the floor surface 2 in the lateral direction of the main body 1.

This straight traveling motion of the main body 1 is possible because the main body 1 is tilted in any direction and the outer peripheral edge of the lower end of the support shaft 12 contacts the floor surface 2. No running operation is performed when the vehicle is standing upright. The front auxiliary legs 11a and 11b prevent the main body 1 from falling, and at the same time, when the doll main body 1 loses its balance due to the slope or unevenness of the floor while the doll main body 1 is running, the front auxiliary legs 11a and 11b prevent the main body 1 from falling. , 11b appropriately contact the floor surface 2 to change the direction of the doll body 1.

When the toy main body 1 rotates and moves as described above, if it collides with an obstacle such as a wall, the rotating member 18
The protrusions 19 come into contact with the obstacle to alleviate the shock of the collision, and the toy main body 1 can be flipped in the opposite direction and turned over.

Further, the toy main body 1 can be rotated in an inverted state with the protrusion 7 at the tip of the head touching the floor 2, as shown in FIG. In this case as well, the flywheel 13 is rotated using the rack belt 16.
Since the center of gravity of the toy body 1 is deviated rearward from the axis, the toy body 1 stands upright about the protrusion 7, but rotates in a distorted state due to the inertia of the flywheel 13.

The left and right arm members 5, 5 of the main body 1 have the distal end shaft portion 21 of the shoulder joint portion 20 rotatably supported within the body portion 3, and are connected to a hinge on the outside thereof. , 5 can be rotated horizontally or vertically.

When the arm members 5, 5 are extended horizontally, the tip of one palm 5a is placed on the floor 2, and the flywheel 13 is rotated, the upper part of the main body 1 becomes small with the arm member 5 as a fulcrum as shown in FIG. Rotate in a circle.

Although not shown, when the flywheel 13 is rotated by placing the protruding outer peripheral surface of the flywheel 13 on the floor 2, the main body 1 can move straight in the horizontal direction at a high speed.

The present invention can be implemented in the following manner in addition to the above. The one shown in FIG. 5 is an example of this, in which the flywheel 13 is rotated at high speed on a floor 2 whose periphery is high and whose central part is low, and a plurality of main bodies 1 having protrusions 19 on the outer peripheral surface are normally installed. Stand it upright and place it on the plate surface 2a. If the two main bodies 1, 1 accidentally come into contact while rotating, they will strongly repel each other by the rotating protrusions 19, and the one that loses balance will roll over, which can cause problems such as American football, sumo wrestling, etc. You can compete in games.
If a large plate with a high edge is used as the table on which the main body 1 is placed, the main body 1 will turn over even if it comes into contact with the edge of the plate, so it can run freely in all directions on the plate surface, making it endlessly interesting.

Effects of the invention The flywheel toy configured as above is
It is possible to run while standing by using the rotation of the spindle to which the flywheel is attached, and it is also possible to run on the outer circumference of the flywheel by laying the main body sideways and placing it on the floor. This makes it possible to provide a highly playable toy with movements not found in conventional toys.
