Biped toy that can walk on two feet

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...

AI Technical Summary

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.
