Abstract

Abstract The invention relates to a running toy having a self-contained motor assembly. The running toy is provided with a pivoting member and a mechanism by which it is actuated in response to the motion of part of the motor assembly to make the running toy somersault when the running toy is traveling along a support surface. The somersault may be rearward or forward. The pivoting member may be manually locked so that the motor will not actuate it.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 320 words
A self-propelled toy vehicle capable of both a translational and predetermined rotational movement in a play action mode of operation, comprising: a frame member having a longitudinal axis and a first and second end; a front wheel assembly attached to the frame member; a rear wheel assembly attached to the frame member; a spring-powered motor assembly attached to the frame member and capable of operatively driving one of the front and rear wheel assemblies for translational movement of the vehicle across a support surface, the wheel assembly driven by the motor assembly also providing an energizing mode of operation to provide a wind-up force for storing energy in the motor assembly, and means for intentionally propelling the frame member above the support surface and rotating the frame member about an axis traverse to the longitudinal axis while above the support surface during a predetermined period of its translational movement including a pivoting member attached to and extending parallel to the longitudinal axis of the frame member's lower surface, means for biasing the pivoting member to rotate from an initial position adjacent a first end of the frame member parallel to the longitudinal axis to a final release position also parallel to the longitudinal axis adjacent the second end of the frame member, and a release means connected to the motor assembly for initiating the rotational movement, the release means including a gear driven by the motor assembly, a cam rotatably mounted and a one-way-clutch mechanism to permit the gear to move the cam in one direction only, whereby the motor assembly can store energy without activating the cam and can activate the cam in a running mode of operation, when the cam is activated the pivoting member can rotate the vehicle above the support surface and can assume a released position parallel to the longitudinal axis whereby the vehicle can continue its translational movement when it contacts the support surface.
Claim 2
Dependent Claim 320 words
A self-propelled toy vehicle capable of both a translational and predetermined rotational movement in a play action mode of operation, comprising: a frame member having a longitudinal axis and a first and second end; a front wheel assembly attached to the frame member; a rear wheel assembly attached to the frame member; a spring-powered motor assembly attached to the frame member and capable of operatively driving one of the front and rear wheel assemblies for translational movement of the vehicle across a support surface, the wheel assembly driven by the motor assembly also providing an energizing mode of operation to provide a wind-up force for storing energy in the motor assembly, and means for intentionally propelling the frame member above the support surface and rotating the frame member about an axis traverse to the longitudinal axis while above the support surface during a predetermined period of its translational movement including a pivoting member attached to and extending parallel to the longitudinal axis of the frame member's lower surface, means for biasing the pivoting member to rotate from an initial position adjacent a first end of the frame member parallel to the longitudinal axis to a final release position also parallel to the longitudinal axis adjacent the second end of the frame member, and a release means connected to the motor assembly for initiating the rotational movement, the release means including a gear driven by the motor assembly, a cam rotatably mounted and a one-way-clutch mechanism to permit the gear to move the cam in one direction only, whereby the motor assembly can store energy without activating the cam and can activate the cam in a running mode of operation, when the cam is activated the pivoting member can rotate the vehicle above the support surface and can assume a released position parallel to the longitudinal axis whereby the vehicle can continue its translational movement when it contacts the support surface.
Claim 3
Dependent Claim 34 words
The invention of claim 1 wherein the pivoting member is attached adjacent the front wheel assembly and is biased to rotate about its attachment point to urge the toy to perform a front somersault.
Claim 4
Dependent Claim 34 words
The invention of claim 1 wherein the pivoting member is attached adjacent the rear wheel assembly and is biased to rotate about its attachment point to urge the toy to perform a rear somersault.
Claim 5
Dependent Claim 23 words
The invention of claim 1 wherein the pivoting member can be further maintained in a biased lock position by a manual locking means.
Claim 6
Dependent Claim 42 words
The invention of claim 1 wherein the release means further includes a pivotally mounted lock member that is resiliently biased to a lock position and a cam mechanism driven by the motor assembly to cam the lock member to an open position.
