  • Patent number: 5178386
    Abstract: A throat piece for a racket includes a throat body made of a transparent rigid plastic and having a series of spaced string holes formed thereon. The throat body has a curved top face, a bottom face and a pair of racket engaging sides which interconnect the top and bottom faces. The bottom face is formed with a narrow card receiving slot of predetermined depth so as to receive a thin printed card. At least one of the engaging sides is provided with a socket to receive a decorative plug. A protective string guide is disposed adjacent to the bottom face and has a plate portion which supports the printed card in the card receiving slot and a series of tubular string receiving portions extending upwardly from the plate portion and into the string holes. The throat piece can thus obviate the need for executing a painting or fastening step to print the manufacturer's logo or brand name thereon.
