Abstract
A chuck for use with a driver, the chuck including a body having a nose section defining an axial bore and a tail section. A plurality of jaws is in communication with the axial bore. A first sleeve is rotatably mounted to the body so that rotation of the sleeve moves the jaws either toward or away from a longitudinal center axis of the axial bore. A second sleeve is rotatably mounted to the body and is movable between a first position in which the second sleeve is rotatably fixed to the body and a second position in which the second sleeve is rotatable about the body. The second sleeve moves in a direction transverse to the longitudinal center axis of the axial bore when moving between the first position and the second position.
Claims14
A chuck for use with a manual or powered driver having a rotatable drive shaft, said chuck comprising:
- a generally cylindrical body having a nose section and a tail section, said tail section being configured to rotate with said drive shaft and said nose section having an axial bore formed therein;
- a plurality of jaws movably disposed with respect to said body and in communication with said axial bore;
- a nut rotatably mounted about said body such that rotation of said nut in said closing direction moves said jaws toward a longitudinal center axis of said axial bore and rotation of said nut in said opening direction moves said jaws away from said longitudinal center axis;
- a first sleeve rotatably mounted about said body such that rotation of said first sleeve in said closing direction moves said jaws toward said longitudinal center axis of said axial bore and rotation of said first sleeve in said opening direction moves said jaws away from said longitudinal center axis;
- and
- a second sleeve rotatably mounted to said body and rotatably fixed to said nut, said second sleeve including a first portion and a second portion, each said first and second portions being movable in a direction transverse to said longitudinal center axis,
- wherein said first portion of said second sleeve moves radially outward away from said longitudinal center axis and said second portion of said second sleeve moves radially inward toward said longitudinal center axis when said chuck transitions from a first state in which said nut is rotatable about said body to a second state in which said nut is rotatably fixed to said body.
A chuck for use with a manual or powered driver having a rotatable drive shaft, said chuck comprising:
- a generally cylindrical body having a nose section and a tail section, said tail section being configured to rotate with said drive shaft and said nose section having an axial bore formed therein;
- a plurality of jaws movably disposed with respect to said body and in communication with said axial bore;
- a first set of locking teeth disposed on said body;
- a nut rotatably mounted about said body such that rotation of said nut in a closing direction moves said jaws toward a longitudinal center axis of said axial bore and rotation of said nut in an opening direction moves said jaws away from said longitudinal center axis;
- a first sleeve rotatably mounted to said body such that rotation of said first sleeve in said closing direction moves said jaws toward said longitudinal center axis of said axial bore and rotation of said first sleeve in said opening direction moves said jaws away from said longitudinal center axis;
- and
- a second sleeve rotatably mounted about said body, said second sleeve including a first portion and a second portion, each said first and second portions being movable in a direction transverse to said longitudinal center axis, and one of said first portion and said second portion including a second set of locking teeth,
- wherein one of said first portion and said second portion of said second sleeve moves radially outward away from said longitudinal center axis and the other of said first portion and said second portion of said second sleeve moves radially inward toward said longitudinal center axis when said chuck transitions from a first state in which said nut is rotatable about said body to a second state in which said nut is rotatably fixed to said body.
