Abstract
A tennis racquet having a stringing pattern in which there are fewer transverse than longitudinal strings, and with the longitudinal strings being interwoven with the transverse strings and preferably being arranged in spaced pairs. The longitudinal strings may be retained against lateral displacement by transverse connectors, which in one form of the invention are cords tied by figure 8 knots to the longitudinal strings, and in another form of the invention may be elongated integrally molded elements containing preformed apertures for receiving and locating the longitudinal strings.
Claims24
A racquet comprising:
- a racquet body having a loop portion and a handle portion projecting therefrom;
- and
- longitudinal and transverse strings carried by said loop portion of the body and crossing one another;
- said transverse strings being fewer in number than said longitudinal strings;
- said longitudinal strings in advancing past successive transverse strings being interwoven therewith so that an individual longitudinal string has portions received at different sides of different transverse strings;
- said longitudinal strings being arranged in pairs with the two strings of each pair being closely proximate one another and with successive pairs being spaced apart a distance greater than the individual strings of a pair;
- the two strings of one of said pairs being formed of a single continuous length of string material doubled back on itself at one end of said two strings of that pair;
- the opposite ends of said two strings of said pair extending through a common opening in said loop portion of the racquet body and then extending laterally in opposite directions from said opening to form two additional pairs of the strings.
