Abstract

See full text

A sliding trap door butt cap for use on a sports racquet such as a tennis racquet includes a cap base and a removable cap plate. The bottom of the cap base has a rectangular guide opening including a pair of opposed keyways, and a ramp portion extending from the keyway on the inwardly facing surface of the cap base. A cap plate has a pair of L-shaped legs extending from the upper surface. The legs are inserted into the respective keyways, and then slid along the ramp portions to draw the cap plate against the cap base. Preferably, the base has an outer border that defines a socket for receiving the cap plate, and the cap plate further includes a tab that engages the guide opening when the cap plate is in position over the socket, so as to lock the cap plate.
