Benefits of technology

[0029] Additionally, the fulcrums of the leg portions are positioned rearward in order to eliminate unstable actions of the leg portions. In addition, the fulcrum of the torso is positioned rearward in order to eliminate unstable actions of the torso. Furthermore, the fulcrums of the left and right foot portions are positioned either inwardly or outwardly in order to eliminate unstable actions of the toy main body.

Problems solved by technology

When walking a conventional biped toy scuffs with left and right feet thereof being in contact with the ground or the like and therefore the toy cannot walk as smoothly as a robot walks.
With the prior art, however, since the aforesaid technique of shifting the weight and center of gravity has not been materialized, if the natural walk is tried to be realized by lifting up the left and right legs of a biped toy alternately, the toy falls down, and therefore when walking the toy has to scuff with the left and right feet thereof being in contact with the ground or the like.

Embodiment Construction

[0051] The particulars shown herein are by way of example and for purposes of illustrative discussion of an embodiment of the present invention. The description taken with the drawings makes it apparent to those skilled in the art how the present invention may be embodied in practice.

[0052] FIG. 1 is a perspective view showing an external appearance of a biped toy that can walk on two feet according to the present invention. A toy main body 1 is made to mimic a robot and is constructed by assembling together a head portion 10, a torso 20, two arm portions 30 and two legs 40. A waking action according to the invention is realized by shifting the torso so that the weight of the torso is shifted and shifting the center of gravity of the toy betwee the two legs 40, and actions of the head portion 10 and the two arm portions 30 are not associated with the walking action but in order to realize natural walking actions the head portion and the two arm portions are made to move in associati...

Abstract

By attaining a certain correlation between shifting the weight of a toy main body and shifting the center of gravity the toy main body between legs thereof there is provided a biped toy that can walk on two feet as naturally as a human being walks without falling down. Left and right legs can be forwarded as naturally as the human being does by positioning the center of gravity above one of the legs which supports the toy main body. With a view to eliminating unstable actions of leg portions, fulcrums thereof are positioned rearward, with a view to eliminating unstable actions of a torso, a fulcrum thereof is positioned rearward, and with a view to eliminating unstable actions of the toy main body, fulcrums of the left and right foot portions are each positioned either inwardly or outwardly.

Description

[0001] 1. Field of the Invention[0002] The present invention relates to a biped toy that can walk on two feet as naturally as a human being walks by lifting up left and right legs thereof alternately while shifting the weight of the toy main body.[0003] 2. Description of the Related Art[0004] When walking a conventional biped toy scuffs with left and right feet thereof being in contact with the ground or the like and therefore the toy cannot walk as smoothly as a robot walks.[0005] In order to allow a biped toy to walk as naturally as a human being does there is a certain correlation to be attained between shifting the weight of a toy main body and shifting the center of gravity thereof between the legs thereof.[0006] With the prior art, however, since the aforesaid technique of shifting the weight and center of gravity has not been materialized, if the natural walk is tried to be realized by lifting up the left and right legs of a biped toy alternately, the toy falls down, and ther...
