Abstract

A gyroscopic walking toy is described having a housing adapted to be positioned for motion in a horizontal direction, a gyroscopic element rotatably mounted from the housing for rotation in a substantially vertical plane, a leg frame and a pivot for connecting the leg frame and the housing for pivotal movement therebetween. Relative movement of the leg frame and housing is produced by a crank geared to the gyroscopic element and linked to the leg frame whereby rotation of the gyroscopic element causes relative movement of the leg frame and the housing while maintaining the gyroscopic element in a substantially vertical plane thereby lifting one of the legs off a supporting surface. Feet can be rotatably positioned at the bottom of the leg since the housing and leg frame pivot around one foot when the other foot is elevated.

Claims

1. A walking toy comprising

a housing adapted to be positioned for motion in at least one given horizontal direction,

a gyroscopic element for rotation,

means for supporting said gyroscopic element from said housing for rotation in a substantially vertical plane,

leg support means connected to said housing for supporting said housing on a support surface,

said leg support means including a leg frame connected to at least two spaced apart feet, and

means for pivotally mounting said feet from said leg frame whereby said housing and leg frame are able to pivot around one of said feet while the other of said feet is elevated above the support surface

whereby gyroscopic action of said gyroscopic element during rotation enables lifing of a portion of said leg support means from the surface and said gyroscopic action also enables forward motion of said leg support means.

2. The walking toy of claim 1 wherein said substantially vertical plane is parallel to said one given horizontal direction and means pivotally connecting said leg frame to said housing.

3. A walking toy comprising;

a housing adapted to be positioned for motion in at least one horizontal direction,

a gyroscopic element for rotation,

means for supporting said gyroscopic element from said housing for rotation in a substantially vertical plane,

said substantially vertical plane being parallel to said one given horizontal direction,

leg support means connected to said housing for supporting said housing on a support surface and including a leg frame connected to at least two spaced apart feet, and

means pivotally connecting said leg frame to said housing,

said pivotally connecting means including an axis positioned substantially horizontal and aligned substantially with said one given horizontal direction.

4. A toy that undergoes walking motion comprising:

a housing,

a gyroscopic element rotatably mounted within said housing for rotation in a substantially vertical plane,

a leg frame,

at least a pair of spaced apart feet connected to said leg frame,

means for connecting said leg frame and said housing for pivotal movement therebetween,

a pair of spaced apart legs connected to said leg frame and

a link member pivotally connected to said legs, said link member and said leg frame maintaining said legs parallel.

5. A toy that undergoes walking motion comprising:

a housing,

a gyroscopic element rotatably mounted within said housing for rotation in a substantially vertical plane,

a leg frame,

at least a pair of spaced apart feet connected to said leg frame,

means pivotally mounting said feet from said leg frame whereby, when one of said feet is elevated, said housing and said leg frame pivot around the other of said feet,

and means for connecting said leg frame and said housing for pivotal movement therebetween.

6. The toy of claim 5 including

crank means rotatably mounted on said housing and interconnected with said gyroscopic element for rotational movement in accordance therewith and

means linking said crank means with said leg frame for movement of said leg frame relative to said housing in response to said movement of said crank means

whereby rotation of said gyroscopic element causes relative movement of said leg frame and said housing while maintaining said gyroscopic element in a substantially vertical plane thereby lifting one of said feet off a supporting surface.

7. A toy that undergoes walking motion comprising

a housing

a gyroscopic element rotatably mounted within said housing for rotation in a substantially vertical plane,

crank means rotatably mounted on said housing

gear means rotatably mounted on said housing and interconnecting said crank means with said gyroscopic element for movement of said crank in response to movement of said gyroscopic element,

a leg frame comprising

a leg frame member

a pair of leg members pivotally mounted on opposite ends of said leg frame member

a foot pivotally connected to each of said leg members,

a leg linking member pivotally connected to said legs, said leg frame member and said linking member maintaining said legs substantially parallel,

means pivotally connecting said leg frame and said housing for pivotal movement therebetween about a fore-and-aft pivot, and

means linking said crank means with said leg frame for movement of said leg frame relative to said housing in response to movement of said crank means and said gyroscopic element

whereby rotation of said gyroscopic element causes relative movement of said leg frame and said housing while maintaining said gyroscopic element in a substantially vertical plane thereby lifting one of said feet off a supporting surface and pivoting said frame around the other of said feet and then lowering said one foot and raising said other foot for rotation of said housing around said one foot thereby moving said housing in generally one horizontal direction.
