Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD This invention relates to a novel rotating traveling toy that moves by rotating wheels and rolling the entire toy.

Prior Art and Its Disadvantages All conventional running toys move by rotating wheels on a running surface, and the way they move is almost the same as that of a real car, and there is nothing different from what you would expect. , the way the game progresses does not give the player any surprises.

Purpose of the Invention This invention provides the ability to travel by rotation of the wheels on the running surface (hereinafter referred to as "wheel running") and the running of the toy itself by devising the shape of the main body of the running toy and the mounting position and mode of the running wheels. To provide a rotating running toy that exhibits a very interesting progress mode that cannot be expected from conventional products by alternately repeating running by rolling on a surface (hereinafter referred to as rolling running).

Embodiments of the present invention [Basic structure and its operation] The basic structure for achieving the above-mentioned object of the present invention is to apply rotational force by a helical wheel to the inside of a hollow notched sphere cut out along the horizontal plane at the bottom. The present invention is characterized in that a given wheel is provided, and a part of the outer peripheral surface of the wheel is made to protrude outside from the bottom surface of the notched sphere.

With this configuration, when the wheels are brought into contact with the running surface and the toy is pushed in the direction of travel, the wheels first rotate on the running surface and move forward due to the inertial rotation of the hand wheel, and during this run, the toy moves forward. As the wheels experience running resistance due to surface irregularities or dirt on the running surface, and the running speed changes, the notched sphere tilts slightly forward and the front end of the bottom comes into contact with the running surface, which creates momentum. The toy, which is moving by inertia, begins to roll and progresses by rolling. When the wheels come into contact with the running surface again due to the rolling, the wheels that are receiving the inertial rotational force of the wheel drive will run, and from then on, the wheels will continue to run and roll alternately in the same way. This continues until the car's inertial motion stops.

[Specific Embodiment] Next, an embodiment of the present invention will be described based on the drawings.

The rotating traveling toy T according to the present invention includes a hollow notched sphere A cut out along the horizontal plane at the bottom as described above, and is attached to the inside of this notched sphere, and receives rotational force by at least a handwheel and this handwheel. As shown in the preferred example shown in the figure, it consists of a wheel B that also serves as a handwheel. The wheel is rotatably mounted with a part of its outer periphery protruding outward from a hole 1 at the bottom of the notched sphere.

In addition to the above basic configuration, as a preferred embodiment,
An additional configuration as described later is added to cause a robot or monster drawn on the outer circumferential surface of the sphere to behave as if it were to spew fire from its mouth while the sphere was running.

FIGS. 2 and 3 show an example of a structure that facilitates attachment of the above-mentioned basic structure to a wheel that also serves as a handwheel and ancillary structures to a notched sphere. A preferred embodiment of the present invention will be described in detail with reference to the figure. The notched sphere A has left and right half members A ₁ , A ₂ having substantially the same shape and having a hemispherical shape notched at the lower part.
are butted together at their peripheries, and one half member is
It is formed by passing a screw from the outside into a cylinder 2a provided inside A ₂ and screwing it into a screw receiving cylinder 2b provided inside the other half member A ₁ .

C is a frame for attaching a wheel B that also serves as a handwheel and ancillary components inside the notched sphere A;
A wheel B, which is formed in an inverted U-shape and also serves as a handwheel, is rotatably supported by a shaft 3 at the bottom, a file wheel 4 is rotatably supported by a shaft 5 above the wheel, and a gear 6 is mounted between these wheels. is rotatably supported by a shaft 7, and gears 8, 9, 10 are fixed to the side surfaces of the wheel B, the gear 6, and the file wheel 4, respectively.
By engaging the wheels B in the required order, the rotation of the wheel B is transmitted to the file wheel 4, and both rotate in the same direction. And frame C
A flint stone 11 is provided on the top of the file wheel 4 so that its lower end surface comes into contact with the top surface of the file wheel 4 due to its own weight.

Before the notched sphere joins the two half members A ₁ and A ₂ , the frame C fits into the groove 13 of the fixing plate 12 formed inside each half member, and the bottom surface of the frame is connected to each half member. The lower outer circumferential surface of the wheel B is brought into contact with the upper surface of the bottom part 14 of the wheel B, and the lower outer circumferential surface of the wheel B is made to protrude outside through the hole 1 formed in the bottom part, and then the two halves are joined together to be installed in the notched sphere. By providing a pair of upper and lower protrusions 17 on both left and right sides of the frame C, and inserting the fixing plate 12 between the protrusions, the upper reaction of the toy load applied from the wheels when the toy is placed on the running surface The frame is fixed without being moved upwards.

Holes 13f and 1 are provided on both the front and rear surfaces of the notched sphere A, passing through on the tangent between the file wheel 4 and the flint stone 11.
3r is provided.

With the above structure, as shown in FIG. 1, this toy rotates when the notched sphere A is grasped and the wheels B are made parallel to the running direction and brought into contact with the running surface and pushed forward. When you let go of your hand in this state, the wheels also function as handwheels, so they rotate due to inertia and move on wheels. Also, since the file wheel is rotated, the hole 1
Sparks are emitted from 3f or 13r.

In this case, since the wheel B is heavy, the higher the rotation speed, the more the wheel B exerts a gyroscope effect, so that the notched sphere corrects its lateral inclination and tries to run in an upright state. Also, when the initial speed is low or when the running speed becomes slow, the wheels will sway from side to side, but since the wheels are protruding from the notched surface of the notched sphere, even if there is some shaking, the notched surface will come into contact with the running surface. Therefore, the wheels can continue to run stably without immediately rolling from side to side.

On the other hand, when the wheel receives running resistance due to unevenness of the running surface or dust on the running surface while the wheel is running, the notched sphere tilts forward, so that the front part of the notched surface The notched sphere A starts rolling due to this momentum.

When wheel B contacts the running surface due to rolling, wheel running is performed again, rolling running is performed under the same conditions, and as illustrated in FIG. 4, wheel running and rolling running are repeated alternately.

The transition period between wheel running and rolling running depends on the speed,
This is subtly related to the position of the center of gravity of the toy as a whole and the condition of the running surface. When the center of gravity is high, the stability of wheel running is low even at relatively slow speeds, and the proportion of rolling motion is higher than that of wheel running. On the other hand, when the center of gravity is low, the stability of wheel running is high even at relatively high speeds, so the proportion of wheel running increases. When the center of gravity is located slightly above the wheel axis, the ratio of wheel running to rolling running is appropriate, and various running modes can be obtained depending on the speed.

If the outer peripheral surface of the notched sphere is smooth, it always moves straight in a fixed direction during rolling. This lacks variety and gets boring quickly. A fixed convex portion 1 is provided on the outer circumferential surface of the notched sphere in Figures 1 and 2.
4 are provided. The convex portions may be scattered or may be provided continuously. By providing such a convex portion, when the turning traveling toy rolls, the convex portion acts to change the traveling direction, so that the toy meanderes in an unexpected direction.

5 and 6 show examples in which one or more movable convex portions 15, 16 are provided on the outer peripheral surface of the notched sphere. By orienting the movable convex portion in an arbitrary direction, it is possible to roll and travel in a different direction each time the vehicle travels. Therefore, this can be used in games where points are determined by the direction of movement.

Effects of the Invention As described above, the rotating traveling toy according to the present invention includes a hollow notched sphere having a horizontal notched surface at the bottom, and is provided inside the notched sphere, with a part of the circumferential surface extending outward from the notched surface. It has a wheel that protrudes from the top and receives rotational force from a hand wheel attached to the notched sphere, so the alternating cycles of wheel running and rolling motion are very interesting and cannot be expected from conventional products. It is possible to provide a rotating traveling toy that shows a progress mode.
