Abstract: A basketball net, fabricated from a combination of elastic and non-elastic cords, is designed to be disposed substantially in the horizontal geometric plane defined by the basketball hoop. The no-hang feature of the net deters players from hanging and swinging from the net.

Abstract: The present invention provides a hollow golf club head comprising a metal striking insert and a composite body. The metal striking insert (1) is molding within the front face wall (2) of the club head body and is securely attached at the outside perimeter of the insert to the composite body and at the front corners of the composite body through the use of a sandwiched structure (7,8, &9). The sandwich structure formed at the boundaries of the striking metal insert efficiently dissipates the impact energy affected when a golf ball is hit. The structure also dampens efficiently the vibrations of the shock affected when the ball is hit on the metal striking insert. The present invention of positioning the insert inside the face wall, not extending outside the face wall, uses less metal material which is heavier than the composite material and makes a larger club head at the same total weight of the club head.

Abstract: The present invention is a golf ball that has a coefficient of restitution at 143 feet per second that is greater than 0.8015, and an USGA initial velocity less than 255.0 feet per second. The golf ball is preferably a solid three-piece golf ball with a thermosetting polyurethane cover, an ionomer blend intermediate layer and a polybutadiene core.

The cord extends along the swivel arm and the support, and one end thereof is connected to the racquet through a stirrup.

Abstract: A swing training golf iron has a solid metal linear shaft attached to an iron golf head and a hand grip. The side of the shaft facing the iron golf head has linear indicia located between the head and grip to provide visual orientation of the angular orientation of the golf head relative to the longitudinal axis of the shaft. The hand grip has a pair of projections for locating the golfer's hand son the grip. Each projection has a V-shaped indicia to aid in the angular orientation of the iron golf head.

Abstract: A basketball shot trainer for controlling the movement of the user's shooting arm in a predetermined direction and predetermined elbow placement. The shooter's arm is connected to an arm bar such that the shooting arm and elbow pivot in a predetermined manner relative to the user's torso. The shooting arm is held in the desired position on the user by means of a back plate which supports the arm bar for pivotal movement to control movement of the user's shooting arm. The arm bar has a guide portion which is secured to the user's shooting arm by an arm band which controls movement of the shooting arm in a predetermined vertical plane.

The present invention relates to a multi-piece solid golf ball comprising a core having at least one layer, an inner cover formed on the core and an outer cover formed on the inner cover, of which the outer cover has many dimples on the surface thereof, wherein a surface hardness in JIS-C hardness of the core is higher than a center hardness in JIS-C hardness of the core by less than 5, the inner cover has a hardness in Shore D hardness of less than 53 and the hardness of the inner cover is higher than the surface hardness of the core, and a hardness of the outer cover is higher than that of the inner cover.

Abstract: A golf swing training device comprises a free-spinning wheel or roller assembly mounted permanently or secured detachably to a golf club of virtually any design, which accelerates learning by conceptually substituting a simple, cohesive, and intuitive action for the complex and seemingly disjointed motions of the golf swing. The position and alignment of the wheel assembly provides inherent and easily discernible visual references with respect to the desired aim and lie angle of the golf club. The user, after adopting an orthodox setup, will be encouraged to roll the wheel back with both arms, and then vigorously and forcibly bring the club and wheel assembly forward toward the intended target to induce momentary, tangential contact with the surface of the ground, causing the wheel to rotate freely—a direct indication of the quality, timing, and speed of the release of the hands.

Abstract: The invention relates to a method for forming golf equipment, or a portion thereof, preferably for forming one or more layers of a golf ball, including: providing a first reactable component containing an isocyanate-containing compound, and a second reactable component containing at least one polyol, polyamine, or epoxy-containing compound; mixing the reactable components together to form a reactive mixture; and injecting the reactive mixture into a cavity or mold having a desired shape within a time sufficient to avoid substantial polymerization, gelation, or solidification.

Abstract: A billiard table includes a table top, and two pairs of bars having an upper portion pivotally secured to the bottom surface of the table top with hinges and foldable toward the table top and foldable away from the table top to an open position. The table top includes two depressions formed in the bottom surface for receiving two opposite hinges, and for allowing two opposite bars to be folded to engage with the bottom surface of the table top. Two pads are secured between the table top and the other pair of bars to be engaged onto the other bars to a compact folding structure.

Abstract: A lace system for a lacrosse stick that restrains thongs from sliding, maintains desired thong tension, enables convenient adjustment of thong length (in the pocket) and thong tension, provides a pocket that enhances ball control, and allows players to cut excess thong lengths to minimize their flapping around during play. The lace system includes specially shaped, sized, and positioned thong holes in the stop member of a lacrosse head, and a lace lock attached to the lacrosse stick below the thong holes. The thong holes in the stop member are not lined up in a straight line, are non-circular in shape, and are slightly smaller than the size of the thongs. The lace lock includes channeling holes and/or channels that align and compress the thongs, ridges that grip the thongs, a compression strap that locks the thongs tightly against the ridges, and a means for attaching the lace lock to the lacrosse stick.

Abstract: A golf club putter head has a unique, geometric configuration that is advantageous for achieving consistently accurate putting shots. The golf putter head of the invention is characterized by a convex complexly contoured ball impact surface and by a high bridge that extends lengthwise at the face of the putter to join the heel and toe. The end extremities of both the putter heel and toe are curved with a complex and unique geometric curvature. Vertical, tapped, chamfered bores are defined in both the putter toe and the putter heel to receive externally threaded inserts. The inserts may be hollow so as to accommodate a variable number of disc-shaped weights, the number of which is individually selected by each golfer. Alternatively, the inserts may be solid structures of a weight suitable to the individual golfer.

Abstract: A hockey practice device which provides physiological memory training to the user includes a low, short open bottom housing having a variable resistance striker puck which slides in a slot in the top of the housing, the puck being secured to a slider beneath the top which is secured to a variable tension extensible and retractable spring member having one end fixed to the housing and the other end to the slider, the entire assembly being only about five feet long or less so as to be usable indoors or outdoors in a minimal space.

Abstract: Slitting shears comprising two knife shafts which are adjustable in relation to one another and are equipped with at least one knife each are described. Some of the knives are adjustable by means of compression springs and with compressed air in the opposite direction in parallel to the axis of the knife shaft. By correspondingly selecting the tensioning force, a machine tool is created which makes possible the automatic adjustment of the tools, especially knives and spring-loaded knives. Besides the reliable contact of the pairs of knives which is achieved as a result, the machine is made ready for operation in a simpler manner and more rapidly, especially in the case of a tool change.
