Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
243 words
A sports racket having a handle comprising a shaft with an end cap at the butt end thereof and a gripping device wrapped spirally over the shaft wherein the gripping device comprises a grip strip having a lead portion arranged to initiate the wrapping of the gripping device onto the butt end of the shaft, a middle portion which covers the majority of the length of the handle, and an end portion which terminates the wrapping at the other end of the handle, said middle portion having a grip surface, an underside contacting the shaft, and two parallel side edges defining the width along the length of said middle portion of said grip strip, said gripping device having raised ridges arranged in a repetative pattern, protruding outward above the grip surface, thereby improving the gripping quality of the gripping surface, and wherein the grip strip is spirally wrapped around the shaft with said middle portion arranged to form a narrow gap between said side edges, said gripping device further including an insertion device adapted to be positioned in said gap for at least the majority of the length of said middle portion, and wherein said insertion device comprises an approximately T-shaped cross-section having a vertical leg and a top wherein the vertical leg is to position the device along the gap between side edges of adjacent grip strips and the top is to cover the side edges which is supporting the insertion device.
