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.
Claims7
A tennis racquet comprising a stringed bow portion defining a string area having an inner periphery which is continuously concave along the length of said bow when viewed from inside the bow, said bow including a base portion to which an elongated handle having a substantially uniform axial cross section immediately adjacent the bow is directly attached, the entire outer periphery of the portion of the bow extending from said base portion and said handle being continuously convex when viewed along a line perpendicular to the string area, the longitudinal axis of said elongated handle being coincident with the major longitudinal axis of said bow, said racquet being yoke free, the cross section of 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, the cross section of said bow being higher and narrower moving from said base portion to the portion opposite said base portion.
A tennis racquet comprising a stringed bow portion having an inner peripheral length which is continuously concave when viewed from inside the bow, said bow portion having a generally ovate shape with a relatively small radius of curvature defining the basal end of said bow and a larger radius of curvature at the opposite end defining the vertex end of said bow, said ovate shape defining a string area, a handle portion having a substantial uniform axial cross section immediately adjacent the bow directly attached at one end to the outer periphery of said bow portion at said basal end, the longitudinal axis of said elongated handle being coincident with the major longitudinal axis of said bow, said bow portion when viewed along a line perpendicular to the string area being continuously convex along its outer peripheral length extending away from the junction between said handle portion and said bow portion, the cross section of said bow portion having a width defined by the distance between the inner and outer periphery of said bow and a height dimension perpendicular to said width, the cross section of said bow becoming narrower in width and having increasing height moving from the basal end towards the vertex of said bow, said racquet being free of a yoke and a shaft.
