Abstract
Abstract A hand-grip for a racket, especially a tennis racket of the type having a hand-grip sleeve formed of longitudinally extending components mountable on a shaft of a racket frame connected to a hitting surface, according to the invention, utilizes at least two similar shell parts, made of a hard, elastic material, that have longitudinally extending edge portions which are arranged in such a way that, when the hand-grip sleeve rests firmly against the shaft, adjacent edge portions laterally overlap without end faces thereof abutting against one another. The hand-grip sleeve is provided with an elastic covering which presses the sleeve against the shaft on all sides.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
120 words
A hand-grip for a racket of the type having a hand-grip sleeve formed of longitudinally extending components joined together about a shaft of the frame of the racket which is connected to a hitting surface, wherein the hand-grip sleeve comprises at least two, at least similar, shell parts made of a hard, elastic material, said shell parts having longitudinally extending edge portions which are arranged in such a way that, when they are formed into said hand-grip sleeve and the hand-grip sleeve is applied firmly against the shaft, adjacent end faces of said edge portions don't abut against one another, and wherein the hand-grip sleeve is provided with an elastic covering which presses it onto the shaft on all sides.
Claim 2
Dependent Claim
120 words
A hand-grip for a racket of the type having a hand-grip sleeve formed of longitudinally extending components joined together about a shaft of the frame of the racket which is connected to a hitting surface, wherein the hand-grip sleeve comprises at least two, at least similar, shell parts made of a hard, elastic material, said shell parts having longitudinally extending edge portions which are arranged in such a way that, when they are formed into said hand-grip sleeve and the hand-grip sleeve is applied firmly against the shaft, adjacent end faces of said edge portions don't abut against one another, and wherein the hand-grip sleeve is provided with an elastic covering which presses it onto the shaft on all sides.
