Moulded resin tennis racket frame - has hollow interfitting string-receiving bosses in two U-section head elements

摘要

The elements (1, 3) are moulded separately in synthetic resin and have U-shaped transverse sections. The base of each U has hollow protuberances where the strings pass through holes in the frame. In one element the hollow protuberance have a projection at the top which fits into a cavity at the top of the protuberances in the other element. The edge of at least one of the elements has groves (8) which fit the edges of the other element. The elements are joined by welding, bonding or any other appropriate means.
