Abstract
A tennis racquet comprising a continuous convex bow containing a plurality of interlaced strings attached under tension, and a handle formed integrally with the bow. The racquet is free of a yoke and a shaft and has a sweet spot located relatively closer to the distal end of the racquet. The racquet exhibits improved stiffness, bending moments and leverage in a racquet having a relatively large head size. The racquet has a higher relative swing weight than other light-weight, large-head racquets by reducing weight at the center of the racquet by eliminating the yoke and throat, thereby providing improved power.
Claims12
A tennis racquet comprising a bow defining a string area, and an elongate handle portion directly connected to said bow, the bow being free of concavity along the length of the outer circumference thereof, said tennis racquet having an overall strung weight of from about 280 to 320 grams, a tip weight of about at least 150 grams, an overall length of from about 66 to 71 centimeters, a handle portion length of from about 17.8 to about 25.4 centimeters, and a string area of from about 710 to about 810 square centimeters.
A tennis racquet comprising a bow enclosing a string area, and a handle integrally joined to said bow, the handle having substantially straight edges with the bow being free of concavity along the length of the outer circumference thereof, the juncture between the bow and the handle being demarcated by an abrupt transition between the convexity of the outer circumference of the bow and the straight edges of the handle whereby said juncture is free of concavity, and said tennis racquet having an overall strung weight of from about 280 to about 340 grams, a tip weight of about at least 150 grams, an overall length of from about 66 to about 71 centimeters, a handle portion length of from about 17.8 to about 25.4 centimeters, and a string area of from about 710 to about 810 square centimeters.
A tennis racquet comprising a bow defining a string area, and an elongate handle portion directly connected to said bow, the bow being free of concavity along the length of the outer circumference thereof, said bow having a width defined by the distance between the inner and outer periphery of said bow and a height dimension perpendicular to said width and said length of said bow, said bow generally tapering in width and increasing in height moving from the proximal to the distal end of said bow.
