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:
- handle means resembling a handle portion of a hand manipulated implement, said handle means having an electrically conductive splined core with a tubular body and a plurality of outwardly extruding spline elements, a non-electrically conductive deformable material annularly disposed around said tubular body of said splined core, and an electrically conductive material annularly disposed around said deformable material and separated from said spline elements by a predetermined distance;
electrical indicator means becoming active when a user has applied an excessive amount of external pressure to said handle means, said excessive amount of external pressure attained when said deformable material allows said electrically conductive material to be deflected said predetermined distance so as to be in contact with any of said plurality of spline elements;
battery means for supplying an electrical current to activate said electrical indicator means; and
circuit means for electrically connecting together said battery means, said electrical indicator means, said electrically conductive material, and said electrically conductive splined core, in a manner such that an electrical circuit with a normally open switch between said electrically conductive material and said plurality of spline elements is formed, wherein said normally open switch is closed when said user has applied said excessive amount of external pressure to said handle means, thereby activating said electrical indicator means and alerting said user accordingly.

Abstract
A pressure-sensitive grip measuring device 10 includes a handle 12 comprised of an electrically conductive splined core 22, a non-electrically conductive deformable material 28 disposed annularly around the splined core 22, a electrically conductive material 34 disposed annularly around the deformable material 28, and a protective material 36 disposed annularly around the electrically conductive material 34 and the entire handle in general. The device 10 also includes an electrically conductive shaft 14 connected to the splined core 22, and a case 16 housing 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 material 34 and the splined core 22. When excessive pressure is applied by a user to the handle 12 the switch is closed and the indicator 20 becomes active. Thus, the user is alerted when such excessive pressure is applied.
