Shock damping racquet butt cap
Abstract
Abstract A butt cap for a racquet comprises walls defining a cavity for slidably engaging the handle of the racquet and walls defining a butt ballast cavity for containing a butt ballast. The butt cap is preferably a ellipsoidal, rounded, tapering approximate egg-shape protruding in excess of 1 cm axially beyond the handle end of the racquet so as to add length to a racquet and provide a comfortable surface such that the player may simultaneously grip the handle and the distal extension, particularly on the serve. The advantage of a butt weight for adding power and control to sports striking implements in general is discussed. A racquet having a distal particulate butt ballast not only damps shock but prevents it by adding more mass to the racquet at the distal end thereof. The butt ballast is preferably of loose metal balls approximately 1 mm in diameter. Retrofit of the butt cap in replacement of a conventional butt cap is possible. Means for attachment of the butt cap include axial extensions extending along the handle.
