Abstract: A tool for realigning or straightening the strings of a racquet. The tool has a generally rectangular tip which is precisely dimensioned to fit within the normal space between the strings of a racquet. To realign the racquet strings, the tip is placed into the space defined by the strings and the strings are automatically adjusted to their preferred alignment. The string straightening tool is portable and compact, allowing the user to carry the device on his/her person and to use the device during lulls in play during the game.

Abstract: An improved ball launching racket has a flexible net disposed within a central opening of a racket by a plurality of removable clip and elastomeric band assemblies. The construction of the clip facilitates expedient mounting and removal of the elastomeric bands, thereby allowing a user to expeditiously change the tension in the net, which in turn, changes the launching characteristics of the ball launching racket. The clip construction promotes usage of elastomeric bands that are free from apertures or slits, so that stress concentration points within the elatomeric bands are eliminated, increasing the useful life of each band.

Abstract: The present invention relates to an method and apparatus for springing sporting racquets to maintain differential tensions between racquet strings within the racquet, so that it is possible to provide racquets having predetermined properties of elastic quality. To maintain differential tensions between the strings, the strings are tensioned against frictional surface, with may be a high frictional surface such as a grommet strip, corner of a racquet string hole, or a pad of high friction material extending about the outer surface of the racquet.

Abstract: A method of stringing a racquet includes independently tensioning a plurality of strings in the racquet and maintaining the independent tensioning. Individual strings are held and their tensioning maintained using cleats and grommets. In this fashion, the elastic properties of the shorter strings may be matched to that of the longer strings, giving a larger sweet spot. The strings may be manufactured as a pre-woven mesh.

Abstract: The sports racquet of the present invention utilizes a series of interlocking string clamping assemblies which are adapted to be received within a corresponding series of passageways formed in the surrounding frame structure of the racquet, and wherein each clamping assembly is adapted to receive and grip a length of playing string which passes therethrough. The clamping assembly is generally comprised of a gripping wedge member and a clamping member, wherein the gripping wedge includes a fastener which secures the wedge to the racquet frame structure prior to application of the clamping member. With the gripping wedge member so positioned and secured within the frame structure, the clamping member is inserted between the wedge and the frame passageway, thereby causing the wedge member to engage and grip the adjacently disposed segment of playing string.

Abstract: A mechanism for adjusting string tension of stringed rackets allows for increasing the tension of the racket strings without having to release the racket strings, without destabilizing the racket and without costly or troublesome aids. The tensioning mechanism includes an abutment piece and a tensioning piece. Strings of the racket pass through both pieces. The tensioning piece is lockable in varying positions to increase string tension. When the racket is strung, the mechanism can be arranged in a position of least tension. In that case, if the string tension declines, the tightening mechanism can be adjusted to a position of the next highest racket tension. Alternatively, the mechanism can be initially set to a medium tension setting and subsequently adjusted as appropriate.
