A racquet for use in playing a simulated tennis game on a court of reduced dimensions having an area approximately one third that of a standard tennis court. The racquet has a strung weight in the range from 340 to 400 grams, a length between 480 and 500 mms, a center of gravity between 240 and 260 mms from the head extremity of the racquet and a radius of gyration in the range from 156 to 176 mms.

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 el...

The invention provides an improved racquet and a method of stringing a racquet wherein the racquet includes grommets that are divided into visually differentiated groups in order to make stringing the racquet quicker and easier. According to one embodiment, the grommets are visually differentiated by color, while in another embodiment, the grommets are visually differentiated by shape.

A racquet string comprises of a core surrounded by at least one sheath, having a plurality of sheath fibers wound around said core, and a coating resin uniting the core and sheath fibers into a unitary body. The sheath fibers are helically wound about the core at a high wind angle, i.e., at a wind angle between 25 and 40 degrees relative to the core axis. Preferably, the sheath comprises a plurality of main sheath fibers and a plurality of non-main sheath fibers, and the core, the main sheath fi...

In a racquet, in particular, a tennis racquet, which incorporates a frame, an open or closed heart piece, and a shaft (2) that is joined to the heart piece, with the frame, heart piece and shaft being formed in one piece or connected releasably to each other, the grip (1) that is formed as a one-piece sleeve can be slid onto the shaft. The inside profile of the cross section of the grip (1) and the outside profile of the cross section of the shaft (2) incorporate longitudinal shape-locking and i...

A tennis racquet is provided with increased resistance against twisting of the racquet frame by increasing the width of the frame just above the area where the yoke and Y-shaped arms of the throat merge with the U-shaped upper portion of the head. The width of the frame in that area is preferably at least 0.600 inch, and more preferably about 0.640 inch. The ratio of the width and the height is about 0.54. The increased resistance to twisting permits the frame to be wider, thereby increasing the...

An improved tennis racquet constructed of magnesium, beryllium or other metal with a low ratio of weight to stiffness and strength wherein the elliptical head of the racquet is disposed so that the long axis of the ellipse is transverse to the axis of the racquet handle, thereby to increase the rotational moment of inertia about the longitudinal axis of the racquet.

A method of stringing a tennis racquet with dual taper strings so as to dispose the smallest diameter strings at the approximate center of the string bed defined by the strings, with the diameter of the string's increasing from such center to the periphery of the frame head. A second method provides a double string bed where the dual taper strings extend over the front and rear faces of the frame head.

The present invention is a racquetball racquet that is substantially longer than a conventional 21 inch racquet, but which has a maneuverability comparable to existing racquets, and on overall playability exceeding conventional 21 inch racquetball racquets. More particularly, a racquetball racquet comprises a frame having a head portion, a handle connected to the head portion, and stringing. The head portion is a thin-wall, hollow composite tubular member having a minimum weight per unit length,...

A paddle or racquet and ball combination is disclosed that is characterized by the provision of a plurality of ball-retaining holes in the face of the racquet having indicia representing a different game on each side arranged in a relationship to the difficulty in catching the ball therein when it is caught on the racquet by a player. The racquet has a flange around its periphery with one or more protruding tabs that are adapted to receive and hold conforming overlays or panels bearing different...
