Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a simple walking toy that moves each leg two steps at a time and walks as if dancing.

(Prior Art) Many so-called walking toys have been commercially available, but all of them have a structure in which the left and right legs are alternately swung to allow walking.

(Technical issues) As a result, the movement was jerky, and the toy was monotonous and uninteresting.

The object of the present invention is to provide a two-step walking toy that can bring about changes in the conventional way of walking as described above and can be implemented on small dolls and the like with a very simple mechanism.

(Technical Means) The object is to provide a pair of left and right legs 3, 4 that are swingably supported on the main body by a support shaft 2 located below and at the rear of the main body 1, and to provide a mechanism for alternately swinging the legs 3, 4. Walking pieces 5 and 6 having an area sufficient to make the main body 1 independent during movement are provided at the lower ends of both legs, and slopes 7 and 8 in the front and back direction are respectively formed on the upper end surfaces of both legs located in front of the support shaft. The walking pieces 5 and 6 are in contact with the walking surface,
With the load of the main body 1 applied thereto, each leg 3, A rotary cam 10 having two protrusions 9 ₁ and 9 ₂ for swinging the rotor 4 in two stages,
Left and right rotating shafts 1 of the power source 11 provided in the main body
2 and 13 are provided with 180 degrees different phase.
Achieved by step walking toys.

(Example) To explain with reference to the drawings, the main body 1 is made up of two members, front and rear, shaped like the torso of a doll, and has a hollow interior in which a so-called pullback spring, which is a power source 11, is housed. , power source holding part 1 to be fixed
4 is formed. In order to enable the left and right legs 3 and 4 to swing back and forth, leg slits 15 and 16 are opened at the bottom of the main body, and both legs 3 and 4 are attached to the shaft 2 located below and at the rear of the main body. This makes it possible to swing around the support shaft. The walking pieces 5 and 6 provided from the lower end of each leg 3 and 4 have a necessary and sufficient area so that they can stand alone together with the main body 1 on one leg and enable alternate walking.

On the upper end surfaces of both legs 3, 4, front-sloping slopes 7, 8 are respectively formed on the parts located in front of the support shaft 2, and the walking pieces 5, 6 are in contact with the walking surface, and the main body 1 When a load is applied to the slopes 7, 8
A power source 11 is provided with a cam 10 that contacts the main body 1 from above and supports the main body 1. The cam 10 is the rotating shaft 1
2 and 13, and by rotating in the direction of following the slopes 7 and 8 from bottom to top, one leg piece 3 moves the walking piece 5 downwardly and backwardly with respect to the other leg piece 4. Let's do it. In order to enable alternate operation of both legs 3 and 4, left and right rotation shafts 12 and 13 of the power source 11
The phases of the rotary cams 10 attached to the two are 180 degrees different.
The cam 10 has a protrusion 1 having the slopes 7 and 8.
a cam surface 19 that can contact 7, 18 and define a leg piece;
, two cam projections 9 ₁ and 9 ₂ are provided, and both projections 9 ₁ and 9 ₂ have different rotation radii and are close to each other.
In addition, 20 is a spring winding knob, and 21 and 22 are retainers facing the front of each leg, which prevent both legs 3 and 4 from rotating around the rear support shaft 2 when the main body 1 is lifted. For leg slit 1
Hook it on the front edge of numbers 5 and 16.

The hands and head of the illustrated toy doll are formed to vibrate easily, and the sway of the two-step gait caused by the mechanism can be amplified. 23 and 24 are left and right hand members,
25 is a head member connected to each connecting protrusion 27 of a trifurcated attachment piece 26 by a flexible tube 28 such as a rubber tube or a coil spring; 29 is a pin for attaching to the main body; 30 is an assembly member. Shows the screws for use.

(Function) In the above configuration, when the power source 11 operates and the left and right rotating shafts 12, 13 rotate in one direction, clockwise in the illustrated example, one of the left and right cams 10, which have a phase difference of 180 degrees, rotates. Touch the slope 7 with the first protrusion 9 ₁ so as to trace it from the bottom to the top, push one shaft 3 backward and downward against the other leg 4 (Fig. 4), and from the first protrusion 9 ₁ When it comes off, the second protrusion 9 ₂ close to it
This is followed by a backward and downward pushing motion (fifth
figure). During this time, the other leg 4, which has a phase difference of 180 degrees, is in contact with the cam surface 19 and hardly moves, but one leg 3
When the leg 4 finishes the walking motion and enters the self-supporting motion, the other leg 4 performs the same walking motion in two stages.

(Effects) Therefore, according to the present invention, the left and right legs 3 and 4 are alternately walked in two steps each by the left and right cams 10 provided at 180 degrees different phases.
A very unusual gait is achieved, and the changing movements are also transmitted to the hands, head, etc., and the whole movement is full of rhythm. In particular, the mechanism for this purpose uses a small power source 11 such as a pullback spring and has a simplified structure, so it is suitable for implementation in extremely small toys characterized by unusual movements.
