<p>The vibration isolating and heat insulating hand grip is for a power driven, manually manipulated impact tool which has a shank that mounts in a chuck. It comprises a rigid, tubular shell of non-porous material which is adapted to surround a tool shank and is open at both ends; a compliant non-porous sleeve within the shell, the sleeve being open at both ends and being large enough that a tool shank extends loosely therethrough. The sleeve has only its end portions bonded to the end portions of the shell, and the shell and sleeve defining an inflatable annular chamber; a cylindrical vibration damping and heat insulating housing surrounding the shell. The dimensions of the housing are such that it may be readily gripped by a human hand; and means operatively associated with the shell for inflating the chamber so the compliant sleeve firmly grips the tool shank, and for deflating the chamber to release the compliant sleeve from the tool shank.</p> |
