ABSTRACT:
A quick release chuck device has a body member defining an axially extending bore for receipt of a tool shank. At least a portion of the bore is defined by a plurality of radially compressible and axially extending gripping segments. The gripping segments are equally spaced and defined by axial slots extending from a front face of the body member. At least two axially extending and aligned recesses are defined on each of the gripping segments. An operating member is coaxial with and surrounds at least the gripping segments of the body member. The operating member defines a varying radial width channel with the recesses formed on the outside of the gripping segments. The operating member is axially movable relative to the body member. Actuating elements, such as balls, are disposed within the varying radial width channels. The actuating elements are movable within the channels by axial movement of the sleeve member from a gripping position wherein the balls are in a reduced radial width section of the channels causing the gripping segments to compress radially inward, and a release position wherein the balls move into a greater radial width section of the channels allowing radial expansion of the gripping segments.
