Abstract
Abstract Game racket having a rigid open cellular network defining the contact surface rather than the conventional stringing, the network and a frame being cast as a single unit and a resilient cylindrical grip being forced over a handle of rectangular cross section and the network consisting of plates whose greatest thickness is less than the width and length.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
210 words
A game racket, comprising: a rigid, one-piece, homogenous frame having a curvilinear head portion, an intermediate throat and shank portion, and a handle portion integral with said head portion; said head, throat, shank, and handle portions having a solid cross-section; at least said head, throat and shank portions consisting of an entirely open-celled network of a plurality of interconnected plates traversing the entire area thereof and forming a honeycomb-like matrix; each of said plates having walls which are perpendicular to the plane of said racket and constituting the width dimension thereof; each of said plates having planar upper and lower surfaces parallel to the central plane of said racket, said planar surfaces being exposed at least at said head, throat and shank portions and constituting two ball contact surfaces of said head portion, the planar surfaces of each of said plates constituting the length dimension thereof; said width dimension being approximately equal to said length dimension; each plate further having a nonuniform thickness with one location of greatest thickness wherein said greatest thickness is less than each of said width and length dimensions and being oriented parallel to said contact surfaces of said racket; and hand grip means covering said handle portion to provide a gripping surface for the user.
Claim 2
Dependent Claim
210 words
A game racket, comprising: a rigid, one-piece, homogenous frame having a curvilinear head portion, an intermediate throat and shank portion, and a handle portion integral with said head portion; said head, throat, shank, and handle portions having a solid cross-section; at least said head, throat and shank portions consisting of an entirely open-celled network of a plurality of interconnected plates traversing the entire area thereof and forming a honeycomb-like matrix; each of said plates having walls which are perpendicular to the plane of said racket and constituting the width dimension thereof; each of said plates having planar upper and lower surfaces parallel to the central plane of said racket, said planar surfaces being exposed at least at said head, throat and shank portions and constituting two ball contact surfaces of said head portion, the planar surfaces of each of said plates constituting the length dimension thereof; said width dimension being approximately equal to said length dimension; each plate further having a nonuniform thickness with one location of greatest thickness wherein said greatest thickness is less than each of said width and length dimensions and being oriented parallel to said contact surfaces of said racket; and hand grip means covering said handle portion to provide a gripping surface for the user.
Claim 3
Dependent Claim
19 words
A game racket as recited in claim 1, wherein said cross-section of each of said plates is a lozenge-shaped.
Claim 4
Dependent Claim
17 words
A game racket as recited in claim 1, wherein said open-celled network extends throughout said handle portion.
Claim 5
Dependent Claim
23 words
A game racket as recited in claim 1, wherein said plates have a smallest thickness adjacent at least one of said contact surfaces.
Claim 6
Dependent Claim
28 words
A game racket as recited in claim 1, wherein said matrix is in the form of square apertures as viewed in the direction perpendicular to said contact surfaces.
Claim 7
Dependent Claim
26 words
