Abstract:
A chuck for use with a manual or powered driver having a rotatable drive shaft, said chuck comprising:a generally cylindrical body member having a nose section and a tail section, said tail section being configured to mate with said drive shaft and said nose section having an axial bore formed therein;a grip mounted in said body member in communication with said axial bore;a generally cylindrical sleeve rotatably mounted about said body member;a driver mounted about said body member and in operative communication with said grip so that rotation of said driver in a closing direction moves said grip radially away from said axis, wherein said driver is in operative communication with said sleeve so that said sleeve is rotatable with respect to said driver between a first position and a second position; anda pawl having a deflectable burr biased toward a catch in said driver,wherein said sleeve defines a cam surface disposed with respect to said catch and said burr so that said cam surface disengages said burr from said catch when said sleeve is in said first position with respect to said driver and releases said burr to engage said catch, and rotationally fix said pawl to said driver, when said sleeve is in said second position with respect to said driver, andwherein said pawl is rotationally fixed to said body when said sleeve is in said second position.
