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.
