摘要： The present invention is a racquetball racquet that is substantially longer than a conventional 21 inch racquet, but which has a maneuverability comparable to existing racquets, and on overall playability exceeding conventional 21 inch racquetball racquets. More particularly, a racquetball racquet comprises a frame having a head portion, a handle connected to the head portion, and stringing. The head portion is a thin-wall, hollow composite tubular member having a minimum weight per unit length, and has a cross-sectional height between 15 and 28 mm, a cross-sectional width between 9 and 13 mm, and defines an egg shape strung surface having a length of at least 14 inches, and preferably between 14 and 15.5 inches, and a strung surface area greater than 95 square inches, and preferably between 100 and 125 square inches. The racquet has an overall length that is substantially greater than 21.0 inches, but less than such length as would result in a strung weight exceeding 250 grams or a mass moment of inertia about the handle end exceeding 23.0 g-m.sup.2. Preferably, the overall length is between 21.5 and 22.5 inches, and the weight is under 220 grams.

摘要： A composite sports racquet includes a head portion which is formed by an upper frame half and a lower frame half. Each frame half is a tubular frame section, and includes a generally flat wall. The two walls are bonded to one another to form a unitary head portion, whereby the first and second walls form internal frame ribs oriented generally parallel to the string bed plane and extending continuously around the head portion. The upper and lower frame halves are preferably pre-molded individually and thereafter glued to one another. Alternatively, one of the frame halves can be pre-molded, with the other frame half thereafter molded onto the pre-molded half Preferably, the first and second walls include a plurality of channel portions which, when the racquet halves are joined, define the string holes. Preferably, the channel portions are contoured at the outer frame surface to form curved bearing surfaces for string entry. Also, if desired, the string holes can be molded so as to extend parallel to the string ends, rather than perpendicular to the racquet frame as is generally done with drilled string holes. Preferably, the string holes have a dimension, in a direction perpendicular to the string bed plane, which is substantially greater than the diameter of standard racquet strings, so that the strings are supported only on the outer portion of the frame, thereby extending the effective string length.

摘要： A handle for a sports implement comprises a handle portion having an outer surface containing a decorative design. A grip sleeve made of a relatively thin, translucent, and preferably transparent, elastomeric material, is sized to cover the handle portion and be in frictional contact therewith, such that said decorative design shows clearly through. In the case of sports racquets, the handle portion may be formed either by a pallet on the racquet shaft, or by a molded-in handle.

摘要： A sports racquet, e.g., a tennis racquet, has an elastomeric pallet that slides onto the racquet shaft. The pallet is formed preferably with a pair of opposed axially extending guides formed on opposed interior surfaces of the pallet. Each guide defines a pawl member. The racquet shaft includes a pair of guide grooves, to receive a respective guide and pawl member, and each groove contains a mating ratchet member. When the pallet slides on the shaft, the guides slide along the guide grooves, until the pawl members and ratchet members engage, which locks the pallet at a predetermined position on the shaft against reverse movement. Due to the fact that the pallet can be easily mounted on the shaft, without the need for adhesive or mechanical fasteners, retailers can carry separate inventories of pallets and racquets, and the customer can select the desired pallet model and handle size at the time of purchase.

摘要： A retention device for use with an object having a handle, such as a racquetball racquet, comprises a wrist ring for securing the device about a wrist of a person gripping the handle, an elastomeric connecting member, and a securing means remote from said ring for securing said device to a handle. In one preferred embodiment, the ring and connecting member are elastomeric loops linked together. Alternatively, the ring and connecting member may be a unitary piece formed of elastomeric material, and the securing means is in the form of a loop portion or other securing means at the remote end of the connecting member. The connecting loop or loop portion are preferably secured by a pin inside the butt of the racquet handle.

摘要： A sports racquet includes a power ring, spanning the throat region of the head, which has an arcuate bearing surface facing away from the outer head portion of the racquet. The bearing surface bows in the direction of the stringing area. The lower ends of the main strings wrap about the bearing surface of the power ring, and the strings extend outwardly in a fan shape configuration to frame. The power ring has the effect of shortening the center strings, and lengthening the outlying main strings, so that the power provided by the strings is more uniform over the string bed.

摘要： A grommet member for use with a sports racquet comprises a grommet strip from which a plurality of hollow grommet pegs project for receiving racquet strings. The strip additionally includes at least grommet having at least two holes for receiving a pair of strings. Preferably, such grommet is either a multi-hole grommet or a triple hole grommet. The holes of the multi-hole grommet may be disposed on opposite sides of the grommet strip axis or alternately along the axis. In one embodiment, the multi-hole grommet includes a notch extending from its distal end partially towards said grommet strip to divide the end of the grommet into a pair of separate barrels, each barrel containing one of the two string holes Multi-hole grommets can be used to replace the shared grommet hole presently used on some sports racquets, in which the hole receives two racquet strings, i.e., either a cross-string and main string, or a main or cross-string and a tie-off string end. Triple hole grommets can receive both a main string and a cross-string and, in addition, receive a tie-off string end. The multi-hole grommet offers the same advantages as known shared grommet holes, in terms of reducing the number, and increasing the spacing, of the string holes in the corners of the frame, but overcomes the present drawbacks of the shared grommet hole in terms of difficulty of stringing and possible grommet failure.
摘要翻译： 用于运动球拍的索环构件包括索环带，多个中空索环栓从该索环条突出，用于接收球拍绳。 带材还包括至少具有至少两个用于接收一对绳子的孔的护环。 优选地，这种索环是多孔索环或三孔索环。 多孔索环的孔可以设置在索环带轴线的相对侧上或者可以沿轴线布置。 在一个实施例中，多孔索环包括从其远端部分地朝向所述索环条延伸的凹口，以将索环的端部分成一对独立的桶，每个筒包含两个串孔之一多孔索环 用于替换目前在一些运动球拍上使用的共享索环孔，其中孔接收两个球拍弦，即，交叉弦和主弦，或主弦或交叉弦和连线弦结束。 三孔索环可以接收主弦和十字串，另外还可以接收一个拉杆串。 多孔索环提供了与已知的共享索环孔相同的优点，就减少框架角落中的孔洞的数量和增加间距而言，克服了共同孔眼孔的现有缺点 穿着困难和可能的索环失败。

摘要： A sports racquet has a head portion with an elliptical cross-section in which the major axis is oriented parallel to the string plane. Preferably, the racquet includes a pair of converging throat frame members, and a throat bridge, which also have elliptical cross-sections oriented parallel to the string plane. As an alternative to a conventional throat bridge, in which some of the main strings are secured to the sides of the frame, a power ring, which bows inwardly toward the strung surface, spans the throat area, and supports the all the main strings, which are wrapped therearound. The racquet provides improved playability for hitting spin shots, by reducing wind resistance and reducing the minimum required angle of incidence (making it easier to hit the ball). Also, the hoop strength of the racquet is increased, which is particularly advantageous when using a power ring, which needs to provide tension to all the main strings.

摘要： A sporting good implement, such as a hockey stick or ball bat, includes a main body. The main body may be formed from multiple layers of a structural material, such as a fiber-reinforced composite material. One or more microlattice structures may be positioned between layers of the structural material. One or more microlattice structures may additionally or alternatively be used to form the core of a sporting good implement, such as a hockey-stick blade. The microlattice structures improve the performance, strength, or feel of the sporting good implement.
