  • Patent number: 11660682
    Abstract: A chuck (10) is provided that includes a plurality of jaws (20) and a body (30) configured to rotate with a drive spindle of a power driver. The chuck (10) may also include a nut (80) comprising nut teeth (82). The nut (80) may be operably coupled to the jaws (20) and configured to move the jaws (20) relative to the body (30) in the opening or closing direction. The chuck (10) may also include a clutch (100) comprising clutch teeth (102). The clutch (100) may be configured to move between a working position and a jaw actuating position. In the working position, the clutch teeth (102) may be engaged with the nut teeth (82) to prevent movement of the nut (80) relative to the body (30), and, in the jaw actuating position, the clutch teeth (102) need not be engaged with the nut teeth (82) and the nut (80) may be free to move relative to the body (30).

  • Patent number: 11511354
    Abstract: A chuck (600) for use with a powered driver having a rotatable drive shaft is provided. The chuck may include a body, a plurality of movable jaws (610), a nut (625), a sleeve (640), and an anti-vibration assembly (620). The anti-vibration assembly may be operably disposed between the sleeve and the nut and configured to absorb vibration caused by operation of the power driver and maintain a position of the sleeve relative to the nut when the sleeve is in at least a locked position.

  • Patent number: 11364547
    Abstract: A chuck for use with a power driver having a rotatable drive spindle is provided. The chuck may comprise a plurality of jaws, a front body, a nut, a rear body, and a clutch. The clutch may be configured to move between a working position and a jaw actuating position. In the working position, the clutch teeth may be engaged with the rear body teeth such that rotation of the rear body by the drive spindle rotates the clutch, the front body, and the jaws. In the jaw actuating position, the clutch teeth may not or need not be engaged with the rear body teeth and the rear body may be configured to rotate the nut relative to the front body to move the jaws relative to the front body.

  • Patent number: 11203070
    Abstract: A chuck configured to be operably coupled to a power driver having a rotatable drive spindle is provided. The chuck (100) may include a body (130) having a center axis (50) and a plurality of clamping jaws (101) configured to clamp onto a working bit. The clamping jaws (101) may be configured to angularly translate relative to the center axis towards or away from a clamping jaw point of convergence (154) to close or open a working bit opening defined by the clamping jaws (101). The clamping jaw point of convergence (154) may be on the center axis. The chuck (100) may also include a plurality of bit alignment jaws (150). The bit alignment jaws (150) may be configured to maintain the working bit within the working bit opening by being configured translate towards or away from a bit alignment jaw point of convergence (153) that is on the center axis (50) and disposed rearward of the clamping jaw point of convergence (154).

  • Publication number: 20210370414
    Abstract: A chuck is provided for use with a powered driver having a rotatable drive shaft. The chuck includes a plurality of jaws movably disposed in passageways of a cylindrical body, a nut rotatably mounted about the body and in communication with the jaws such that rotation of the nut in a closing direction moves the jaws toward each other and rotation of the nut in an opening direction moves the jaws away from each other, and a sleeve rotatably mounted about the body. The sleeve is in communication with the nut such that rotation of the sleeve rotationally drives the nut. The chuck also including a biasing element disposed between the nut an at least a portion of the sleeve configured to bias the sleeve toward a neutral position. The biasing element limits an inertial force of the sleeve applied to the nut during operation of the powered driver.

  • Patent number: 11123806
    Abstract: A chuck is provided for use with a powered driver having a rotatable drive shaft. The chuck includes a plurality of jaws (22) movably disposed in passageways (40) of a cylindrical body (14), a nut (16) rotatably mounted about the body (14) and in communication with the jaws (22) such that rotation of the nut (16) in a closing direction moves the jaws (22) toward each other and rotation of the nut (16) in an opening direction moves the jaws (22) away from each other, and a sleeve rotatably mounted about the body (14). The sleeve is in communication with the nut (16) such that rotation of the sleeve rotationally drives the nut (16). The chuck also including a biasing element (208) disposed between the nut (16) an at least a portion of the sleeve configured to bias the sleeve toward a neutral position. The biasing element (208) limits an inertial force of the sleeve applied to the nut during operation of the powered driver.

  • Patent number: 10603722
    Abstract: A chuck (10) has a body (14), a plurality of jaws (22), and a rotatable nut (16). A sleeve (18) is rotatable between a first rotational position and a second rotational position with respect to the nut. An annular array of first teeth (84) are non-rotatable with respect to the body. One or more second teeth (63) are non-rotatable with respect to the nut and axially movable with respect to the body. When the teeth engage, they resist the nut's rotation in the opening direction. An engagement between the sleeve and the one or more second teeth moves the one or more second teeth out of engagement with the first teeth when the sleeve moves from the second rotational position to the first rotational position and moves the one or more second teeth into engagement with the first teeth when the sleeve moves from the first rotational position to the second rotational position.

  • Patent number: 10239127
    Abstract: A chuck has a body (14). A plurality of first teeth (96) are rotationally fixed to the body. At least one second tooth (100) opposes the first teeth. The first teeth and the at least one second tooth are configured so that engagement of the first teeth and the at least one second tooth prevents relative rotation between a nut (16) and the body in an opening direction. A sleeve (18) defines a notch (90b) that engages a spring (29) so that in a relative rotational position between the sleeve and the nut, the notch receives the spring so that the notch resists relative rotational movement between the sleeve and the spring in the opening direction of the chuck.
