Abstract
Abstract A multi-purpose game puck formed of relatively hard material and being generally cylindrical in shape with upper and lower flat star-shaped surfaces adapted to slide over a playing surface and indented surfaces between the star points to provide air channels and which aid in movement over rough or irregular playing surfaces, and circular recesses formed in the center of each star-shaped surface to provide an air pocket which is effective to cushion the puck as it slides over irregular surfaces with air flowing into the pocket via the air channels.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
98 words
An aerodynamic multi-purpose game puck comprising a generally cylindrical rigid member including at least one flat sliding surface generally star-shaped in configuration and adapted to slide upon a playing surface, and a plurality of circumferentially spaced indentations, each located between adjacent points of said star-shaped sliding surface and tapering toward the center to terminate at an apex between opposite edges associated with said star-shaped surface, said indentations providing air channels along the leading edge of the puck when in motion to produce mild lifting forces and to aid the puck in passing over irregularities on the playing surface.
Claim 2
Dependent Claim
98 words
An aerodynamic multi-purpose game puck comprising a generally cylindrical rigid member including at least one flat sliding surface generally star-shaped in configuration and adapted to slide upon a playing surface, and a plurality of circumferentially spaced indentations, each located between adjacent points of said star-shaped sliding surface and tapering toward the center to terminate at an apex between opposite edges associated with said star-shaped surface, said indentations providing air channels along the leading edge of the puck when in motion to produce mild lifting forces and to aid the puck in passing over irregularities on the playing surface.
Claim 3
Dependent Claim
38 words
The structure set forth in claim 1 wherein said game puck includes a central recess in said star-shaped sliding surface which serves as an air pocket to cushion the puck when passing over irregularities in the playing surface.
Claim 4
Dependent Claim
53 words
The structure set forth in claim 1 wherein each of said indentations is comprised of a pair of oppositely inclined substantially planar surfaces each defined in part by opposite ones of said star-shaped surface edges, said substantially planar surfaces meeting along a line lying in a radial plane passing through said apex point.
Claim 5
Dependent Claim
38 words
The structure set forth in claim 3 wherein said game puck includes a central recess in said star-shaped sliding surface which serves as an air pocket to cushion the puck when passing over irregularities in the playing surface.
Claim 6
Dependent Claim
25 words
The structure set forth in claim 4 wherein both sides of said game puck are provided with said star-shaped sliding surfaces, indentations, and central recess.
