VIBRATION ISOLATOR FOR HAND-HELD VIBRATING DEVICES

摘要

An isolator is used in a hand-held vibrating device (10) for providing optimum vibration isolation by utilizing buckling elastomer sections (44A) which operate in a buckled mode during normal use. The buckled elastomer sections (44A) significantly reduce the spring rate within an operating load range thus substantially reducing the vibration transmitted to the user. Six embodiments are shown which utilize buckling sections to enhance vibration isolation along an axial direction of vibration. A first embodiment includes a frusto-conical section (20A). A first embodiment of a front grip isolator (30A) that is used with the buckling isolator (20A) for reducing the radial mechanical vibration transmitted to the front hand of the user, also utilizing buckling sections, is also taught.
