Abstract
A pressure-sensitive grip measuring device 10 for use in training or assisting athletes in developing a proper hand grip. The device 10 includes a pressure-sensitive grip 14 comprising an electrically conductive shaft 12 having a plurality of grooves 22 formed annularly therein, a like plurality of elastic insulating rings 24 disposed in the plurality annular grooves 22, and an electrically conductive wrapping 26 disposed annularly around the electrically conductive shaft 12 and the elastic insulating rings 24. The electrically conductive wrapping 26 is typically covered by a non-electrically conductive protective material such as a rubber golf club grip. The device 10 also includes a housing 16, attached to one end of the electrically conductive shaft 12, for retaining a battery 18 and a user detectable indicator 20. An electrical circuit is formed in the device 10 such that a normally open switch is formed between the electrically conductive wrapping 26 and the electrically conductive shaft 12. When an improper amount of pressure is applied by a user to the pressure-sensitive grip 14 the switch is closed and the indicator 20 becomes active. Thus, the user is alerted when such an …
