A sports racquet comprises a handle and a frame coupled to the handle. The frame includes an inner portion and an outer portion located substantially opposite the inner portion. The inner portion of the frame include a plurality of undulations that extend towards and away from a ball-hitting surface, the undulations reducing the unintended bunching and wrinkling of material that intermittently forms in the frame during the manufacturing process. The undulations can be varied by location, undulat...
A sports racquet has a head frame that includes a support member and an inwardly directed alignment member or fin. String segments are strung from a central strung area through respective holes in the fin, around the support member and back through further holes in the fin. The present invention provides a strong anchor for the strings which can withstand the static load thereof as well as dynamic loading placed on it by striking gamepieces as well as striking other objects. In a preferred embod...
A racquet with strings and a handle has at least a portion of the strung length of at least some of its strings at least partially within a cavity defined by the racquet's handle, and/or, in the case of a racquet having a shaft, a cavity defined by the racquet's shaft. Typically two, or some multiple of two, strings are extended in strung length by at least a portion of the length of the handle's (shaft's) cavity. The cavity may be but only slightly recessed into the handle (shaft), and may be n...

A sports racquet strung with a bypass string pattern has a frame with a first side and an opposed second side. The second side of the frame has a plurality of spaced apart string anchoring points. A string bed including a string having a plurality of string segments each strung between the first side and the second side of the frame using the string anchoring points. The string bed includes first and second string segments that are adjacent each other on the string, substantially parallel to eac...
A sports racquet frame is built of a composite of laminations of fibrous material as impregnated by a thermosetting resin. The head section of the frame has an upper tube preferably disposed above the string bed plane and a lower tube preferably disposed below the string bed plane. A solid bridge of material integrally joins the upper tube to the lower tube. In a preferred embodiment the bridge is disposed radially exteriorly of the center line of the tubes, to maximize the length of string segm...
A bearing assembly is at least partly disposed within the hollow stem or handle of a sports racquet. A plurality of curvilinear channels are disposed at different lateral locations in a direction which is at a substantial angle to the longitudinal axis of the racquet. For each channel there are provided a pair of ferrules through which string segments are strung from, and then back to, the string bed. Preferably the ferrules receive ends of tubes through which the string segments are strung. One...
A string guide system is disposed within the hollow stem of a sports racquet and guides the continuous string at least through a turn for redirecting the continuous string back out of the cavity and toward the string bed. The redirection defines shared ends of a pair of connected consecutive string segments. The string guide system disposes the string segments at predetermined lateral positions along the width at least at the turn. In a preferred embodiment the string guide system includes flexi...
A racquet for hitting a projectile has a stem, which is a handle or a shaft with a handle, and a racquet head with a frame extending from the handle and supporting a tensioned string bed defining a sweet spot. The frame has an upper portion on an opposing end of the frame relative to the handle and a longitudinal axis extending from the upper portion to the handle. The string bed includes main strings generally running parallel to the longitudinal axis and cross strings running generally perpend...
A sports racquet strung with a bypass string pattern. The sports racquet includes a frame having a first side and an opposed second side. The second side of the frame has a plurality of spaced apart string anchoring points. A string bed including a string having a plurality of string segments each strung between the first side and the second side of the frame using the string anchoring points. The string bed includes first and second string segments that are adjacent each other on the string, su...
