Abstract

See full text

A racket, especially a tennis racket, having a frame surrounding a stringed hitting area, the frame being formed with a shaft on which a grip sleeve is mounted. In order to ensure that the grip sleeve is very stable and resistant to twisting and is arranged on the shaft either firmly or slidably, while manufacturing tolerances of the shaft and/or the grip shell can still be balanced, the following characteristics are provided: (a) the grip sleeve is formed of one or more parts made of a hard elastic material; (b) inwardly directed position-fixing elements are provided at the inside walls of the grip sleeve, the position-fixing elements centering the shaft in the grip sleeve, at least partly with little tolerance play; (c) spring elements are provided between the inside walls and oppositely facing surfaces of the shaft; (d) the spring elements brace the grip shell in a springy manner, but without play, relative to the shaft; and (e) optionally, the shaft, itself, may be provided with stop surfaces that interact with the position-fixing element to further stabilize the grip against twisting.
