Chuck with quick connect spindle interface

A chuck for use with a rotating power tool having a drive spindle, the chuck comprising:

• a plurality of jaws configured to open or close to install or remove a bit;
• a body assembly being configured to translate rotation of the drive spindle about a center axis of the chuck to the plurality of jaws;
• a detent member movable to engage with the drive spindle to secure the drive spindle to the chuck and disengage from the drive spindle to permit removal of the drive spindle from the chuck;
• a collar comprising a collar recess, the collar being axially movable relative to the body assembly into a spindle disengaged position and a spindle engaged position;
• a collar spring operably coupled to the collar to apply a collar spring bias on the collar;
• and
• a separation spring assembly operably coupled to the body assembly and configured to apply a separation bias on the drive spindle when the separation spring assembly is engaged with the drive spindle;
• wherein, when the collar is in the spindle disengaged position and the detent member is not engaged with the drive spindle, the detent member is at least partially disposed within the collar recess and both the collar and the separation spring assembly apply bias forces on the detent member;
• wherein, when the collar is in the spindle engaged position and detent member is engaged with the drive spindle, the detent member is moved out of the collar recess.

A chuck for use with a rotating power driver having a drive spindle, the chuck comprising:

• a plurality of jaws configured to open or close to install or remove a bit, the jaws being disposed at a forward end of the chuck;
• a body assembly comprising a spindle cavity to receive the drive spindle at a rearward end of the chuck, the body assembly being configured to translate rotation of the drive spindle about a center axis of the chuck to the plurality of jaws;
• a detent member moveable relative to the body assembly, the detent member being movable to engage with the drive spindle to secure the drive spindle to the chuck and disengage from the drive spindle to permit removal of the drive spindle from the chuck;
• a collar comprising a collar recess and a collar engaging surface, the collar being axially movable relative to the body assembly and the detent member into a spindle disengaged position and a spindle engaged position;
• a collar spring operably coupled to the collar to apply a collar spring bias on the collar;
• and
• a separation spring assembly disposed within the spindle cavity and configured to apply a separation bias on the drive spindle when the separation spring assembly is engaged with the drive spindle within the spindle cavity;
• wherein, when the collar is in the spindle disengaged position and the detent member is not engaged with the drive spindle, the detent member is at least partially disposed within the collar recess and the detent member extends into the spindle cavity to operate as a stop for the separation spring assembly.
