摘要： A tennis racket is made lighter than conventional tennis rackets yet has a higher center of percussion and a higher frequency of vibration. The head of the racket is ovoid, and the widest part of the head is above the longitudinal midpoint of the head. The longitudinal strings are fan-shaped and diverge outwardly and upwardly from the bottom of the head.

摘要： A tennis racquet includes a hollow tubular frame defining a head portion, a throat, and a shaft portion supporting a handle. The frame has a height, in a direction perpendicular to the stringing plane, that increases uniformly from the bottomn of the throat to the tip of the head portion, so as to increase in stiffness further away from the handle. Such arrangement, in which the frame is most flexible at the top of the handle, reduces the angle of deflection of the stringing plane upon impact and absorbs shock.

摘要： A racquet includes polyester, monofilament racquet string and a frame extending along a longitudinal axis and including a head portion coupled to a handle portion. The head portion includes a hoop having inner and outer peripheral walls. The hoop defines a head size having maximum longitudinal and transverse dimensions, a, and, b, respectively. The dimension a is at least 1.2 times the dimension b. The inner peripheral wall includes string holes. The string has a diameter within the range of 1.10 to 1.55 millimeters. The string forms a string bed of interlaced main and cross string segments. Each of the cross segments transversely extends from one of the string holes to another, and each of the main segments longitudinally extends from one of the string holes to another. The string bed has at least one more main segment than cross segment. At least one of the main segments contacting the tennis ball exhibits a snap back velocity of at least 1 meter per second.

摘要： A fielding practice bat is disclosed having a frame, preferably U-shaped, integrally connecting a head portion and a handle portion, wherein the fielding practice bat has a length, weight and balance equivalent to a conventional baseball bat. The head portion is generally tear-drop in shape and has a width no greater than 12 inches. In addition, the head portion is interwoven with a plurality of main strands of elastic tubing and a plurality of cross strands of elastic tubing. In the preferred embodiment, a single piece of elastic tubing comprises the main strands and cross stands of elastic tubing wherein the piece of elastic tubing is woven through holes in the frame. A forming grid is also disclosed comprising a matrix of cells. The main and cross strands of the fielding practice bat are interwoven through the cells of the forming grid such that each cell contains a single intersection between a main strand and a cross strand, thereby dampening the vibration of the strands upon contact with a ball.

摘要： 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.

摘要： A game ball racket with a reverse sunburst string pattern comprising a frame shaped to have its free ends extend parallel to form a handle, with its central extent in a general loop shaped configuration to constitute a head, the frame has an axis centrally disposed through the center of the handle and head, the head is formed with a plurality of spaced apertures extending through its periphery. A first string is positioned through first selected apertures in the head to form cross strings perpendicular to the axis and parallel with each other, the cross strings are spaced from adjacent cross strings a distance greater at the end adjacent the handle than at the opposite end with such spacing decreasing in such direction. A second string is threaded through second selected apertures in the head to form main strings nearly parallel to, but offset from, the axis, each main string is positioned at a small angle with respect to the axis and with the main strings further remote from the center line being at a greater angle than the angle of the strings adjacent to the axis with the angle between adjacent strings increasing with the distance away from the axis, the main strings are spaced more widely apart adjacent to the handle than at the end remote therefrom, the main strings and cross strings constituting a planar string bed.

摘要： In construction of a tennis racket provided with an oval Head Frame defining a racket face, the longitudinal size (W.sub.1) of the racket face is set to a value in a range from 320 to 390 mm, the transverse size (W.sub.2) of the same is set to a value in a range from 200 to 240 mm, and the longitudinal compressive rigidity of the head frame is adjusted to a value in a range from 30 to 200 Kgf/mm. The construction thus specified allows employment of an enlarged main/cross string tension ratio which assures high degree of spin performance at shooting balls.

摘要： The improved racquet has a strung surface which is larger in area than the strung surface of a conventional racquet, and in which the strung area is both longer in length and width than the strung area of a conventional racquet. However, the overall weight and balance of a conventional racquetball racquet which have proven necessary for good playing characteristics for all such racquets have been maintained. The racquet has synergistically combined the weight of the racquet, the center of mass of the racquet, the stiffness of the frame, and the response characteristics to create a racquet of sufficient durability with a larger "sweet spot" to facilitate the playing of the sport and to increase the level of skill, particularly of the novice and intermediate players. The racquet has an overall length of .[.181/2.]. .Iadd.19 .Iaddend.inches to 221/2 inches and a width of 91/2 inches to 111/2 inches, a weight of 220 grams to 270 grams, and a center of gravity at a location within a range of 3/4 inch toward the handle and 1/2 inch toward the head as measured from the longitudinal center point of the racquet.
