Abstract:
A grip assist apparatus that may be worn on either hand that includes a symmetrical non-slip gripping portion that includes a substantially stiff palm arch support, a wrist portion, and a releasable wrist fastener.
Abstract:
During use of a golf club, the impact of the head of the club with a ball causes complex vibrations in the handle that are uncomfortable for the user and may adversely affect the force applied to and energy transferred to the ball. The invention aims to mitigate this problem by providing an end piece attached to an end of a shaft of the golf club thereby defining a tapered termination for an air column defined by said shaft.
Abstract:
Die Erfindung betrifft die Formgebung eines Dämpfers, der für Tennis- und ähnliche Rackets geeignet ist. Die erfindungsgemässe Formgebung kann mit geringem Aufwand hergestellt werden und ermöglicht eine elastische Lagerung einer Masse. Die elastische Lagerung einer Masse erlaubt eine effektive Reduktion von Vibrationen. Diese stark dämpfende Wirkung unterscheidet den erfindungsgemässen von herkömmlichen Dämpfern. Der geringe Aufwand bei der Herstellung liegt darin begründet, dass die erfindungsgemässe Formgebung eine Herstellung aus einem einzigen Material und aus einem Guss ermöglicht, ohne dass Einzelteile zusammengefügt werden müssen. Daraus ergibt sich ein wesentlicher Vorteil in Bezug auf die Herstellungskosten.
Abstract:
A finger position training sports device (100) can include a surface for receiving at least a portion of a hand, a plurality of capacitance sensor areas (104-0 to 104-n) formed on the surface, and a capacitance sense circuit (114) attached to the sports device. The capacitance sense circuit (114) can have an input coupled to each capacitance sensor area (104-0 to 104-n) and a processor circuit that activates an indication value when predetermined sensor areas indicate contact with different portions of at least one hand.
Abstract:
A stem web is disclosed that comprises a backing layer having a first surface 5 and a second surface, and an array of 600 to 20000 upstanding stems projecting from the first surface of the backing. The stems comprise a height from 0.3 and 2.0 millimeters and a shore hardness less than 90A. In one embodiment, the stem web further comprises a reinforcing layer secured to the second surface. In one embodiment, the stem web is secured to a tool to be passed across a surface to be cleaned to capture lint and hair.
Abstract:
A gyroscope assembly is mounted within a sports instrument swing aid. A motor is connected to a rotor within the gyroscope assembly. A power source drives the motor to rotate the rotor. During a forward swing of the swing aid, an angular momentum of the rapidly spinning rotor tends to maintain the swing aid parallel to a plane of the swing. A reaction torque from the gyroscope assembly may be sensed by a player if a player's wrists are rotated in a release, and may also be sensed if a parallel relationship of the swing aid to a plane of the swing is not maintained. The swing aid may be in the form of a bat or racket.
Abstract:
Game apparatus, e.g., a game racquet or a golf club, with selectively variable and maintainable weight distribution, e.g. by moving material (e.g., liquid and/or solid weight members) within or on the apparatus and selectively positioning the weight (s) and maintaining weight position in or on the apparatus.
Abstract:
A system and method for positively identifying a sports bat to ensure the bat has not been tampered or otherwise altered after manufacture includes an RFID tag that is embedded in the bat during the manufacturing process. The RFID tag stores information related to the individual bat. In competition, the information stored in the embedded RFID tag is read using an RFID reading device. If a bat is modified or otherwise altered after manufacture, the RFID tag will be damaged or missing from the modified bat. In that case, the RFID reading device will be unable to properly read the RFID tag and the information stored on the tag, and the bat may be considered "not approved for play." In a similar fashion, the RFID tag may also be used to track and maintain inventory control, while ensuring the bat remains in the same condition as when it was manufactured.
Abstract:
A tennis training aid can be used to teach proper wrist and racket position for swings such as a forehand ground stroke, two-handed backhand stroke, or volley. A training aid includes a forearm attachment member that can be quickly and easily attached to a player's forearm. A wrist positioning member can be attached between the forearm attachment member and the player's racket to maintain proper wrist angle and racket position. A first wrist positioning member can be used for a forehand ground stroke or two-handed backhand stroke, while a second wrist positioning member can be used for volleys. The forearm attachment member can include a rotatable member, and the wrist positioning member can be slightly elastic, in order to allow the racket to move slightly with respect to the wrist, and to allow for slight wrist movement, in order to provide a natural feel for the player.
Abstract:
A golf accessory is provided that includes an insert for removably and interchangeably mounting within an interior of a golf club shaft for interchangeably altering a predetermined stiffness or bending moment of the club shaft.
