Abstract
In a ball-game racket, especially a tennis racket, with a racket head formed by a clamping frame with stringing and with a grip shaft that attaches via, for example, a core piece, a damping element is located on the racket that has at least one additional weight and is elastically mounted with gaps between it and all adjacent walls.
Claims7
A ballgame racket comprising:
- a racket head that is formed by a clamping frame with stringing;
- a grip part that connects to the clamping frame and is formed by a grip shaft or a racket neck;
- a handle;
- a damping element that is provided on the racket neck that has at least one additional weight that is elastically mounted with a gap on all sides between it and adjacent walls, wherein the damping element consists of a sleeve into which an elastic damping material that surrounds the at least one additional weight is inserted under pre-stress and whereby the damping element protrudes from the racket and is at least partially visible.
1 more element
A ballgame racket comprising:
- a racket head that is formed by a head frame, with stringing;
- a grip part that adjoins to the head frame via a core piece, the core piece is formed by a grip shaft or a racket neck with a handle;
- the core piece having a damping element that has at least one additional weight that is elastically mounted therein with a gap on all sides between it and adjacent walls, whereby the core piece is formed by two bridges that extend with one end from the grip shaft and diverge, and with the other end making a transition to the head frame, whereby in the grip shaft a recess is formed which is open toward the core piece or toward the space between the two bridges and which is to accommodate the damping element that is located in the recess, whereby the damping element consists of a sleeve into which an elastic damping material that surrounds an additional weight is inserted under pre-stress.
