Abstract
Abstract A spinning toy or top includes a hollow rotating body with a generally low center of gravity caused by a mass positioned near the bottom of the body and having a portion thereof extending through the lower wall of the body to define a point on which the toy spins. A pair of limbs may be pivotally mounted on the top to be raised or otherwise actuated by centrifugal force upon rotation of the top. A head or similar device may be positioned on the body and coupled thereto for concurrent rotation by frictional forces. The toy is spun by a spinner that includes an elongated screw fabricated in a helical configuration. A handle is secured to the top of the screw and a clutch is mounted on the lower end. The clutch includes a gripping member slidably mounted on the screw so as to rotate when moved relative to the screw. The head member includes a detent mechanism so that the head can be held in a stationary position, or selectively stopped by engagement with the handle.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
107 words
A toy spinning top, comprising: a hollow body; a mass positioned in the lower portion of said body; centrifugally movable limb members pivotally mounted on said body; means for spinning said top including a rotational force transmitting member engageable with said mass and means for rotating said transmitting member upon engagement with said mass, said mass further includes a depending extension defining the point on which said top spins; and a head member positioned on said body to spin therewith by frictional engagement therebetween, said spinning means further including a handle and an extension on said handle, said head member including a detent engageable by said extension.
Claim 2
Dependent Claim
107 words
A toy spinning top, comprising: a hollow body; a mass positioned in the lower portion of said body; centrifugally movable limb members pivotally mounted on said body; means for spinning said top including a rotational force transmitting member engageable with said mass and means for rotating said transmitting member upon engagement with said mass, said mass further includes a depending extension defining the point on which said top spins; and a head member positioned on said body to spin therewith by frictional engagement therebetween, said spinning means further including a handle and an extension on said handle, said head member including a detent engageable by said extension.
Claim 3
Dependent Claim
27 words
The top claimed in claim 1 wherein said spinning means further includes a helical shaft and said transmitting member includes a slot through which said shaft extends.
Claim 4
Dependent Claim
22 words
The top claimed in claim 1 wherein said transmitting member includes a plurality of teeth to grip said mass upon engagement therewith.
Claim 5
Dependent Claim
95 words
A spinning toy, comprising: a body; a mass mounted in said body; first and second centrifugally actuated limb members pivotally mounted on said body; a head member positioned on said body; and means for spinning said toy wherein said spinning means includes a helical shaft and a mass engagement member on said shaft, said mass engagement member including a slot through which said shaft extends, said mass is hollow and said shaft includes a stop member that extends into said hollow mass to allow engagement of said mass engagement member during spinning of said toy.
Claim 6
Dependent Claim
95 words
A spinning toy, comprising: a body; a mass mounted in said body; first and second centrifugally actuated limb members pivotally mounted on said body; a head member positioned on said body; and means for spinning said toy wherein said spinning means includes a helical shaft and a mass engagement member on said shaft, said mass engagement member including a slot through which said shaft extends, said mass is hollow and said shaft includes a stop member that extends into said hollow mass to allow engagement of said mass engagement member during spinning of said toy.
Claim 7
Dependent Claim
25 words
The toy set forth in claim 4 wherein said mass engagement member further includes a gripping surface thereon for gripping said mass and spinning therewith.
Claim 8
Dependent Claim
19 words
The toy set forth in claim 5 wherein said shaft includes a handle, said handle includes an extension thereon.
Claim 9
Dependent Claim
18 words
The toy set forth in claim 6 wherein said head member includes a detent engageable by said extension.
Claim 10
Dependent Claim
107 words
A spinning action toy, comprising: means defining a body; a pair of centrifugally actuated limb members mounted on said body; means for rapidly rotating said body including a spinner means on said body and a pivot member to define the point on which said toy spins, said spinner means further comprises a slide member of a helical configuration, a handle secured to one end and a grip member including a slot through which said slide member extends for engaging said body, said handle includes a generally lateral extension, and a head member loosely mounted on said body, said head member including a detent for engaging said extension.
Claim 11
Dependent Claim
107 words
A spinning action toy, comprising: means defining a body; a pair of centrifugally actuated limb members mounted on said body; means for rapidly rotating said body including a spinner means on said body and a pivot member to define the point on which said toy spins, said spinner means further comprises a slide member of a helical configuration, a handle secured to one end and a grip member including a slot through which said slide member extends for engaging said body, said handle includes a generally lateral extension, and a head member loosely mounted on said body, said head member including a detent for engaging said extension.
Claim 12
Dependent Claim
23 words
The toy defined in claim 8 wherein said head member is positioned on said body and frictionally engaging said body to spin therewith.
Claim 13
Dependent Claim
17 words
The toy defined in claim 8 wherein said limb members are pivotally mounted on said body member.
Claim 14
Dependent Claim
25 words
The toy defined in claim 8 including a weighted element, said weighted element comprising a relatively large mass relative to the mass of said toy.
