Attorney, Agent or FirmInternational ClassG01M 007/00AbstractAn impact gauge for determining the cumulative impact energy along a single axis including a housing having an elongated chamber with a pair of bendable members cantilevered into the chamber, so that when an impacting member positioned in the chamber and proximate bendable member with the impact member having sufficient mass so that when the housing is subjected to an impact, the inertia of the impacting member is sufficient to permanently bend the bendable member so that one can measure the degree of bend of the bendable member which can be correlated with impacts of measured strength to enable one to determine the accumulated impact energy absorbed by the impact gauge. | |
