Abstract: A compound spring element for a game racket frame is provided. A resilient casing forms the spring element, with its profile having a first side portion and a second side portion defining at least one space between them. The at least one space contains at least one damping and/or tension element which interacts with the casing to form a semi-rigid, damped, compound structural unit that is flexurally resistant to string tension. It can be disposed in any number of advantageous positions on at least one part of a head frame to cooperate with at least one string.

Abstract: A racket includes a frame, at least one string and a particular portion The frame includes a handle portion and a head portion. The string is connected to the frame to provide a string tension. The particular portion is composed of a non-fluid material and disposed on the frame. The particular portion cooperates with the at least one string and is designed to reduce the string tension of the string upon a deflection of the string. The particular portion compresses when the string tension of the at least one string increases.
