Provided is a swing speed analyzer for mounting on a swinging implement and comprising a first accelerometer, a processor and a shock attenuator. The processor uses an output from the first accelerometer to compute a swing speed of the swinging implement. The shock attenuator is comprised of a material that is sized and dimensioned to dampen an impact shock wave by more than 50% at 125 Hz. The material is preferably sized and dimensioned to dampen the impact shock wave from more than 1000 g to less than 500 g. Suitable attenuators can include viscoelastomeric materials such as foam. The swing speed analyzer can advantageously include any of a releasable attachment mechanism, a liquid crystal or other visual display, a second accelerometer, and a strain gauge. The analyzer can advantageously be attached to a golf club, a tennis racket, a baseball bat, or a hockey stick.

A method for manufacturing elongate articles such as baseball bats, paddles, oars, hockey sticks, generic tubing and other articles and articles including molded material molded about a preform. The preferred method includes manufacturing a filament wound preform and reaction injection molding material about the preform to result in a finished article. The preferred baseball bat includes an elongate filament wound preform about which a quantity of urethane foam is molded.

A sports article includes a portion that includes a nanostructured material. The nanostructured material includes a metal, and the nanostructured material has an average grain size that is in the range of 2 nm to 5,000 nm, a yield strength that is in the range of 200 MPa to 2,750 MPa, and a hardness that is in the range of 100 Vickers to 2,000 Vickers. The sports article can be any of a variety of sports equipment and associated components, such as a golf club, a baseball bat, a softball bat, a lacrosse stick, or a hockey stick.

An overall fitness trainer and can be a wall mounted unit that can utilize clip resistance bands as well as other techniques. These bands generally clip on the unit and onto different handles, bars and attachments to perform exercises. The unit can have a removable/adjustable pull up bar, dip bar and seat. It also includes a spring loaded, pull pin carriage that moves freely up and down a vertical spine. This allows for easy adjustment of the carriage and allows the user to attach the bands at multiple angles, widths and levels. This in turn increases the number of exercises the user can perform on the unit. The unit can be attached to the wall with lag bolts into two or more studs. Various embodiments of the invention can have an oscillating and telescopic bench, a dip bar, a seat, a knee stabilizer and a foot rest. All of these accessories can be attached and removed to the central spine adding to the versatility and scope of exercises that can be performed. Accessories can also include a baseball bat handle, baseball, medicine ball, boxing gloves, football, squat belt, golf club handle, hockey stick handle, lacrosse stick handle and any other handle of any other sport unit.

Hand interfaces (11), (111), (188), (201a), (201b), (202a), (202b), (204), (211), (311), (411), (511), (611), (711), (811), and (911), which improve the performance of many items including: racquets for tennis and other sports; rotary hand tools such as screwdrivers; hockey sticks; and kayak oars. Relative rotation between one of the hand interfaces and a corresponding implement is selectively stopped, and torque is selectively transmitted between the hand interface and the implement, when a user squeezes the implement's handle. The hand interface can be rotated in either direction on the implement, and relative movement stopped at an infinite number of positions. The hand interface amplifies the opposing effects of either a firm grasp or a relaxed grasp. Tactile indicator systems (36) with (38), and (236a,b) with (238a,b), glove (204), as well as handle grips (611), (711), (811), and (911) which rotate on noncircular shafts, enable users to accurately determine rotational positions of the implement to the hand interface. For additional ease of use, adjustable end-stop systems (273a,b) with (275a,b), or (73f,b) with (86f,b) limit the range of rotation between the hand interface and the implement

A composite hockey stick having a tubular hollow rectangular shaft and a blade is disclosed. The shaft comprises an inner layer and an outer layer, each of the inner and outer layers are formed of uni-directional substantially continuous fibers disposed in a hardened resin matrix and wrapped and molded around a middle elastomer layer. A new manufacturing method is also disclosed in which a cured hollow tubular composite hockey stick shaft is inserted between the front and back faces of an un-cured composite hockey stick blade and the blade is then cured in a mold around the hockey stick shaft to form a unitary composite hockey stick.

Hockey stick configurations and hockey stick blade constructs are disclosed. The blade is comprised of one or more inner core elements, surrounded by one or more walls made of reinforcing fibers or filaments disposed in a hardened matrix resin material. One or more of the inner core elements comprises an elastomer material.

Disclosed is an installation for competitive play with an ice hockey stick and an ice hockey puck. The installation includes a game platform, a goal with targets, target identifiers and a computer. A computer controlled puck circuit includes a puck magazine (30), a passing unit (46) which feeds pucks (1) to a player (40), a conveyor apparatus (2) which sorts and conveys shot pucks (1) into the puck magazine (30). The points value of shots made by the player (40) are evaluated with the help of a light barrier A (48) and a light barrier B (49), a camera (50) und a corresponding underlying computer program and the points assigned form the basis for a competitive play which can be played over the international data network.

A composite hockey stick blade including a fiber reinforced, high-density foam polymeric core material overlaid with a plastic wrap. The fiber reinforcement material, in the form of a plurality of milled or long fibers, provides increased toughness and stiffness of the high density polymeric foam core material. The hockey stick blade may be utilized as a replacement blade for a two-piece hockey stick, or may be a portion of a one-piece hockey stick.

A hockey stick includes a shaft and a blade. The blade has a toe end, a heel end, a top edge and a bottom edge. The blade has an opening portion within a region between the toe portion and 1/3 of a length between the toe portion and the heel portion of the blade from the toe portion.

A method of manufacturing a one piece, composite, hockey stick in an autoclave. A mandrel is provided which has a non uniform cross section. Pre-preg flags are wrapped around the mandrel. Provision is made so that when the wrapped mandrel is inserted in a pressure application tube, a portion of the wrapped mandrel is separated from the pressure application tube by one or more spacers. Pressure is then applied to the pressure application tube which in turn applies the pressure to the spacers. The spacers then apply the pressure to the wrapped mandrel to compact the pre-preg on the wrapped mandrel. Next the spacers are removed and the pre-preg is cured. Finally, a blade is formed around the pre-preg flag.
