Abstract
Abstract A toy robot having a first arm for automatically simulating a karate chop when the second arm is moved slightly. The arm operation is accomplished by rotating the right arm, thereby winding up a spring, and cocking it in a raised position. The cocking mechanism is released to allow the spring to force the right arm downward when the left arm is moved slightly.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
217 words
A toy robot comprising a body, first and second arms, a shaft for mounting said first and second arms in said body, first and second clutch means mounted on said shaft, said first clutch means for engagement with said first arm to permit rotation of said first clutch means on said shaft only when said first arm is rotated in a first direction, said second clutch means for engagement with said second arm to permit rotation of said second clutch means on said shaft only when said second arm is rotated in a first direction, spring means mounted on said first clutch means and adapted to be wound when said first clutch means and said first arm are rotated in said first direction of said first arm, means for cocking said first clutch means and said first arm in a cocked position responsive to the rotation of said first arm and said first clutch means in said first direction of said first arm through a predetermined arc, and means responsive to movement of said second arm and said second clutch means in said first direction of said second arm for releasing said cocking means to allow said spring means to rotate said first clutch means and said first arm in a second direction of said first arm.
Claim 2
Dependent Claim
217 words
A toy robot comprising a body, first and second arms, a shaft for mounting said first and second arms in said body, first and second clutch means mounted on said shaft, said first clutch means for engagement with said first arm to permit rotation of said first clutch means on said shaft only when said first arm is rotated in a first direction, said second clutch means for engagement with said second arm to permit rotation of said second clutch means on said shaft only when said second arm is rotated in a first direction, spring means mounted on said first clutch means and adapted to be wound when said first clutch means and said first arm are rotated in said first direction of said first arm, means for cocking said first clutch means and said first arm in a cocked position responsive to the rotation of said first arm and said first clutch means in said first direction of said first arm through a predetermined arc, and means responsive to movement of said second arm and said second clutch means in said first direction of said second arm for releasing said cocking means to allow said spring means to rotate said first clutch means and said first arm in a second direction of said first arm.
Claim 3
Dependent Claim
217 words
A toy robot comprising a body, first and second arms, a shaft for mounting said first and second arms in said body, first and second clutch means mounted on said shaft, said first clutch means for engagement with said first arm to permit rotation of said first clutch means on said shaft only when said first arm is rotated in a first direction, said second clutch means for engagement with said second arm to permit rotation of said second clutch means on said shaft only when said second arm is rotated in a first direction, spring means mounted on said first clutch means and adapted to be wound when said first clutch means and said first arm are rotated in said first direction of said first arm, means for cocking said first clutch means and said first arm in a cocked position responsive to the rotation of said first arm and said first clutch means in said first direction of said first arm through a predetermined arc, and means responsive to movement of said second arm and said second clutch means in said first direction of said second arm for releasing said cocking means to allow said spring means to rotate said first clutch means and said first arm in a second direction of said first arm.
Claim 4
Dependent Claim
217 words
A toy robot comprising a body, first and second arms, a shaft for mounting said first and second arms in said body, first and second clutch means mounted on said shaft, said first clutch means for engagement with said first arm to permit rotation of said first clutch means on said shaft only when said first arm is rotated in a first direction, said second clutch means for engagement with said second arm to permit rotation of said second clutch means on said shaft only when said second arm is rotated in a first direction, spring means mounted on said first clutch means and adapted to be wound when said first clutch means and said first arm are rotated in said first direction of said first arm, means for cocking said first clutch means and said first arm in a cocked position responsive to the rotation of said first arm and said first clutch means in said first direction of said first arm through a predetermined arc, and means responsive to movement of said second arm and said second clutch means in said first direction of said second arm for releasing said cocking means to allow said spring means to rotate said first clutch means and said first arm in a second direction of said first arm.
Claim 5
Dependent Claim
35 words
A toy robot in accordance with claim 1 wherein said first direction of said first arm is opposite to said first direction of said second arm when looking at said body from either side thereof.
Claim 6
Dependent Claim
25 words
A toy robot in accordance with claim 2 further including means for biasing said first and second clutch means toward opposite ends of said shaft.
Claim 7
Dependent Claim
25 words
A toy robot in accordance with claim 1 further including means for biasing said first and second clutch means toward opposite ends of said shaft.
Claim 8
Dependent Claim
40 words
A toy robot in accordance with claim 1 further including means for limiting the arc through which said first arm and said first clutch means can be rotated from any initial position in said first direction of said first arm.
Claim 9
Dependent Claim
127 words
A toy robot in accordance with claim 5 wherein said cocking means includes a lug on said first clutch means and stop means mounted for movement away from said first clutch means when said lug bears against it during rotation of said first arm and said first clutch means in said first direction of said first arm, said stop means being operative to spring back toward said first clutch means after said lug has cleared it to thereafter block movement of said first clutch means in said second direction of said first arm under the force of said spring means, and said releasing means is operative to move said stop means away from said first clutch means when said second arm is rotated in its first direction.
