Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
246 words
A game racket comprising an elongated frame member formed into a loop and having converging portions forming a throat and handle portions extending beyond said throat; said racket having a longitudinal axis; a yoke disposed parallel with the plane of said loop and connecting said converging portions of said elongated frame member across said throat; said converging portions having inner surfaces directed toward said axis, outer surfaces directed away from said axis, and substantially parallel front and rear side surfaces; said yoke having on each lateral side an oppositely facing, converging grip portion which is wider than said converging portions in a front to rear direction and comprises a bottom wall and outwardly directed substantially parallel flanges defining a channel shaped to substantially conform to the inner surfaces of said converging portions of said frame member, said inner surfaces of said converging portions nesting within said channels between flanges and on said bottom wall and said flanges surrounding substantial portions only of said front and rear sides of said converging portions of said frame member; means securing said channels to said converging portions of the frame member; said yoke also having a bridge means connecting said grip portions to each other across said throat, said bridge means including (a) string mounting means disposed along the lateral edge of the bridge means facing inwardly of said loop, and (b) a rigid body portion disposed on the outward side of said string mounting means away from said loop.
Claim 2
Dependent Claim
246 words
A game racket comprising an elongated frame member formed into a loop and having converging portions forming a throat and handle portions extending beyond said throat; said racket having a longitudinal axis; a yoke disposed parallel with the plane of said loop and connecting said converging portions of said elongated frame member across said throat; said converging portions having inner surfaces directed toward said axis, outer surfaces directed away from said axis, and substantially parallel front and rear side surfaces; said yoke having on each lateral side an oppositely facing, converging grip portion which is wider than said converging portions in a front to rear direction and comprises a bottom wall and outwardly directed substantially parallel flanges defining a channel shaped to substantially conform to the inner surfaces of said converging portions of said frame member, said inner surfaces of said converging portions nesting within said channels between flanges and on said bottom wall and said flanges surrounding substantial portions only of said front and rear sides of said converging portions of said frame member; means securing said channels to said converging portions of the frame member; said yoke also having a bridge means connecting said grip portions to each other across said throat, said bridge means including (a) string mounting means disposed along the lateral edge of the bridge means facing inwardly of said loop, and (b) a rigid body portion disposed on the outward side of said string mounting means away from said loop.
Claim 3
Dependent Claim
41 words
A game racket as set forth in claim 1 wherein said means securing said channel to said converging portion comprises fastening means extending through said converging portion of said frame member and anchored to said bottom walls of said grip portions.
Claim 4
Dependent Claim
59 words
A game racket as set forth in claim 2 wherein said rigid body portion of the bridge means of said yoke is integrally joined with said grip portions and comprises a relatively thin web portion spaced from said string mounting means; at least one edge of said web having an integral, enlarged reinforcement portion extending between said grip portions.
Claim 5
Dependent Claim
42 words
A game racket as set forth in claim 1 said means securing each of said channels to its corresponding converging portion of said frame member comprises fastening means extending through said outwardly extending flanges and said converging portion of the frame member.
Claim 6
Dependent Claim
