  • Patent number: 5439216
    Abstract: The training device assuring a proper grip utilizes a thin sheet wrap sized to wrap around an outside grip surface of a racket handle. A non-domed membrane switch is retained by the thin sheet wrap. A releasable element is utilized to secure the wrap on the racket handle. This releasable element can be a releasable adherent. A portable power source is electrically coupled to an audible alarm, both of which are in turn electrically connected to the switch. When the switch closes, the alarm sounds. Other than a switch, piezoelectric pressure sensors can be utilized. The method includes removably mounting at least one membrane switch with a wrap about a racket handle, mounting a portable power supply in an audible alarm on the racket, electrically connecting together the power supply, alarm and switch, compressibly closing the switch with a proper hand grip over a distance which does not exceed the thickness of the wrap, and audibly announcing the closure of the switch by activation of the alarm.

  • Patent number: 5431395
    Abstract: The device tests the pressure and positioning of a player's hand on the grip of sports equipment. The device generates an audible signal of confirmation when a lower threshold of pressure at predetermined locations on the grip are achieved. In many sports a major hindrance to a player in perfecting his or her game is the lack of maintaining a proper grip on the sports equipment. An important aspect of many sports including tennis, racquetball, golf, baseball and hockey is to maintain proper hand position and a firm grip on the sports equipment used. This sports equipment includes, amongst others, the tennis racket in tennis, the racket in racquetball, the golf club in golf, the bat in baseball and the stick in hockey. Proper grip and the ability to properly maintain the correct grip on the equipment is of paramount importance to consistent play.
