Description

[Detailed Description of the Invention] The present invention relates to a rotating walking toy that can continuously rotate and walk on a slope.

Traditionally, it has been known to attach a weight to the bottom of a doll, and when the doll is pushed down, it returns to its previous position due to the action of the weight.

There are also toys in which a transfer path is provided in a hollow body, a weight is housed in the hollow body, and the toy is rolled on a flat surface or an inclined surface.

However, the movements and changes of these toys lacked interest, and they did not fully satisfy the sense of dynamism and interest.

Therefore, the present invention aims to eliminate the above-mentioned drawbacks and provide an interesting rotating walking toy that can walk nine times continuously on slopes or stairs while providing unprecedented interest and variety. It is.

Now, one embodiment of the rotary walking toy according to the present invention will be described with reference to the drawings. 1 is a substantially rectangular hollow body, and 2 is a transfer surface of this hollow body 1.

3 is a weight of an iron ball housed in the hollow body 1.

4 is a pair of front legs rotatably supported on the side of the hollow body 1 via a pin 5; 4' is a pair of front legs rotatably supported on the side of the hollow body 1 via a pin 5';
A pair of rear legs rotatably supported on the sides of the
Each of them is formed in a substantially inverted T shape.

However, the attachment positions of the front leg 4 and the rear leg 4' are determined at such intervals that the legs 4, 4' do not come into contact with each other while the hollow body 1 is rotating and walking.

Reference numerals 6 and 6' denote protrusions provided at the tips of the front leg 4 and the rear leg 4', respectively.

As will be described later, these protrusions 6, 6' serve to enable the main body of the hollow body 1 to walk stably even on steep slopes and stairs.

The weight of the projections 6 and 6' is appropriately such that the chest center line of the legs 4, 4' is slightly retracted when the main body of the hollow body 1 is lifted horizontally.

Therefore, the protrusion 6,
6' is not necessary, and the front portion thereof may be made slightly heavier than the rear portion.

7°7' is an arcuate portion formed at the rear part of both legs 4, 4'.

Therefore, the pivot point of the front leg 4 is slightly below the center of gravity axis A of the hollow body 1, and the pivot point of the rear leg 4' is slightly above the center of gravity axis A of the hollow body 1. Please provide one.

This displacement of the pivot point has the function of enabling continuous rotation of the hollow body 1, as will be described later.

Note that in the drawings, 8 and 8' indicate bearings.

Next, the operation of the present invention will be explained.

As shown in FIG. 3, when the toy according to the present invention is placed at the top of a slope, the weight 3 inside the hollow body 1 rolls on the transfer surface 2 due to the gradient of the slope, and the tip of the inside of the hollow body 1 rolls. Go to section.

Therefore, due to the weight of the weight 3 and the fact that the front legs 4 are pivotally attached to the hollow body 1, the hollow body 1 is lifted from the rear and rotated.

At this time, the rotation of the hollow body 1 causes the rear leg 4' to move forward of the hollow body 1, but since the pivot point of the rear leg 4' is above the center of gravity axis A of the hollow body 1, it moves forward. As a result of this movement, its pivot point will be located below the center of gravity axis A of the hollow body 1.

Therefore, the front leg of the hollow body 1 is always below the center of gravity axis A, so the hollow body 1 makes a full rotation (18
0°).

Then, since the weight 3 reciprocates inside the hollow body 1,
The hollow body 1 can rotate continuously on the slope.

Also, at this time, the tips of the legs 4, 4' are the protrusions 6, 6'.
are provided, so that when the hollow body 1 rotates and lands, the protrusions 6, 6
The weight of the legs 4, 4' brakes the forward movement of the legs 4, 4', thereby preventing them from being thrown forward, making it possible to rotate and run stably even on steep slopes or stairs.

At the same time, the rear of both leg bodies 4, 4' are circular arc-shaped parts 7, 7.
', so even if the legs 4, 4' move forward when the hollow body 1 rotates and lands, there is no risk that the arcuate parts 7, 7' will touch the slope and the hollow body 1 will fall. .

This is particularly effective on steep slopes and stairs.

In this way, the hollow body 1 repeats the above-mentioned operation and moves down the slope or stairs while rotating.

In this embodiment, an iron ball is used as the weight 3, but a liquid may be used instead.

Further, a connecting rod may be attached between the front leg 4 and the rear leg 4'.

However, in this case, the connecting rod causes friction losses, so the slope needs to have a greater slope than without the connecting rod.

Since the present invention is constructed as described above, it can continuously rotate and walk on a slope, and it can provide fun and variety that was not previously available in toys of this type. You can make it even more interesting by drawing faces etc.

It also has excellent effects such as a simple structure and low cost.
