ABSTRACT:
A bumper strip assembly for sports racquets comprises a bumper strip portion, which may be a conventional bumper strip, and preferably a pair of polymeric felt or urethane foam strips. The cushion strips preferably have a density in the range of 0.35-0.60 g/cc and a hardness in the range of 50-60 Shore A durometer, and are disposed between the bumper strip flanges and the outer surface of the racquet frame. The cushioning strips are very lightweight, having a combined weight on the order of 3 grams, yet are extremely effective in protecting the frame from damage due to impact with a hard court surface.
