Pressure-sensitive grip measuring device
First Claim
1. A pressure-sensitive grip measuring device for training or otherwise assisting users in perfecting a proper hand grip, said pressure-sensitive grip measuring device comprising:
- pressure-sensitive grip means resembling a grip portion of a hand manipulated implement, said grip means comprising an electrically conductive shaft having a plurality of grooves formed annularly therein at a first end thereof, an elastic insulating ring disposed in each of said plurality annular grooves, and an electrically conductive wrapping disposed annularly around said electrically conductive shaft and said elastic insulating rings but separated from said electrically conductive shaft by a predetermined distance;
electrical indicator means becoming active when a user has applied an improper amount of external pressure to said grip means, said improper amount of external pressure attained when said elastic insulating rings allow said electrically conductive wrapping to be deflected said predetermined distance so as to be in contact with said electrically conductive shaft;
battery means for supplying an electrical current to said electrical indicator means for activating the same; and
circuit means for electrically connecting together said battery means, said electrical indicator means, said electrically conductive wrapping, and said electrically conductive shaft, in a manner such that an electrical circuit with a normally open switch between said electrically conductive wrapping and said electrically conductive shaft is formed, wherein said normally open switch is closed when said user has applied said improper amount of external pressure to said grip means, thereby activating said electrical indicator means and alerting said user accordingly.

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 improper amount of pressure is applied.
