  • Publication number: 20250108440
    Abstract: A chuck (300) may include a lock disk (380), a ball retainer (350), a lock sleeve (360), a wedge pin (371), and a pin drive spring (320). When the lock sleeve (360) is disposed in the locked position, the wedge pin (371) may be positioned by the pin drive spring (320) in a wedged engagement between a pin engaging surface of the ball retainer (350) and a lock disk wall (381) of the lock disk (380) to prevent rotation of a first sleeve (30) and a nut (40) relative to a body (41) in a first rotational direction but permit rotation in a second rotational direction. When the lock sleeve (360) is disposed in the unlocked position, the wedge pin (371) may be positioned by the pin drive spring (320) such that the wedge pin (371) is not in the wedged engagement to permit rotation of the first sleeve (30) and the nut (40) in the first rotational direction and second rotational direction.

  • Patent number: 12202055
    Abstract: A chuck for use with a power driver having a rotatable drive spindle is provided. The chuck may include a sleeve comprising a sleeve tightening surface that may be configured to engage with a nut tightening surface to tighten a nut when the sleeve is rotated into a tightening position. With the sleeve disposed in a sleeve locked position, a click pawl may be engaged with a click stopping edge of one of the plurality of click teeth to inhibit rotation of the nut in a first rotational direction to loosen the nut. A lock pawl may also be engaged with a lock stopping edge of one of the plurality of lock teeth to inhibit rotation of the sleeve in a second rotational direction due to the inertia in the sleeve that would tend to further tighten the nut.

  • Publication number: 20240261873
    Abstract: A chuck (10) for use with a power driver having a rotatable drive spindle. The chuck may include a sleeve (60) comprising a sleeve tightening surface (62) that may be configured to engage with a nut tightening surface (502) to tighten a nut (50) when the sleeve is rotated into a tightening position. With the sleeve disposed in a sleeve locked position, a click pawl (732) may be engaged with a click stopping edge (771) of one of the plurality of click teeth (756) to inhibit rotation of the nut in a first rotational direction to loosen the nut.

  • 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: 11344954
    Abstract: Various chucks for use with a power driver having a rotatable drive spindle are provided. One chuck includes a plurality of jaws disposed at a forward end of the chuck, a body, a push plate, a jaw spring, and a nut. The plurality of jaws may be disposed in the body and configured to rotate with the body about a center axis of the chuck. The push plate may be operably coupled to each of the jaws. The jaws may be configured to translate forward to close the jaw opening in response to the push plate translating axially forward. The jaw spring may be configured to apply a forward directed force to urge the push plate forward. The nut may have nut teeth that cause the jaws to translate forward and clamp onto the working bit in response to the nut being rotated in a tightening direction.

  • 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: 11123807
    Abstract: A chuck for use with a power driver having a rotatable drive spindle is provided. The chuck may include a clamping assembly comprising a clamping member that operably couples the sleeve to a nut. The clamping assembly may be configured to transition the chuck between a rapid jaw adjustment mode and a clamping mode. In the rapid jaw adjustment mode, a sleeve may be configured to rotate the clamping member with the nut to cause rotational movement of the nut relative to jaws and a chuck body, which may cause translational movement of the jaws relative to the chuck body. In the clamping mode, the nut may be rotationally fixed with the jaws and the clamping member may rotate relative to the nut to cause the nut to move axially relative to a center axis of the chuck which causes the jaws to translate relative to the body and clamp onto a working bit.
