According to one aspect, a releasable roller clutch includes a shaft and a clutch housing positioned around the shaft. The shaft and clutch housing together defining a space there between with rollers positioned in said space. The rollers permit rotation of the shaft relative to the clutch housing when in an unlocked position in which the rollers are not wedged and prevent rotation of the shaft relative to the clutch housing when in a locked position in which the rollers are wedged. A cage extends into the space defined between the shaft and clutch housing. The cage is moveable relative to the clutch housing between an unlocking position and a locking position. The cage has a contact edge positionable to prevent the rollers from moving from the unlocked position to the locked position when the cage is in an unlocking position. The releasable roller clutch permits rotation of the shaft relative to the clutch housing in both directions when the cage is in the unlocking position.

A quick release device of a hand tool includes: a main body; an operating portion, including a slidable sleeve movably disposed around the main body and a pin radially inserted into the slidable sleeve, the operating portion further including a movable rod movably disposed in the main body, the pin connected with the movable rod; an annular plastic body, rotatably disposed around the slidable sleeve and corresponding to the pin, a stepped structure formed between the slidable sleeve and the annular plastic body; an identification portion, disposed around the annular plastic body; wherein the slidable sleeve is movable between first and second positions, when the slidable sleeve moves toward the first position, the pin drives the movable rod to move toward a fixing position; when the slidable sleeve moves toward the second position, the pin pushes the movable rod to move toward a releasing position.

A locking mechanism for use with a tool has a tool having a first working end, an opposite second end, a central axis therebetween, and a least one axial recess formed on an outer surface of the tool. A cap is rotatably received on the tool opposite second end, the cap comprising at least one recess formed on an outer surface thereon. The cap is rotatable between a first position in which the cap at least one recess aligns with the tool at least one recess, and a second position in which the cap at least one recess is out of alignment with the tool at least one recess. The locking mechanism further comprises a detent operatively positioned between the tool and the cap. The detent may be a pin and a spring, where the spring biases the cap into the second position.

A quick release connector is provided that uses a plurality of the ball bearings to engage shaft of a releasable member. The use of multiple ball bearings along different faces of a shaft of a releasable member minimizes vibrations and provides an improved quick release connector adapted for use with microphones, boom arms, ball joints and similar structures used with sound recording or photography equipment.

The described embodiments provide a subsea connector that is a quickly deployable and reusable. The subsea connector comprises a male and a female assembly that can be connected and disconnected. The male assembly includes a shaft, a sleeve that surrounds the shaft, and bars that are connected to the shaft and are configured to rotate about one axis. The female assembly includes a receptacle into which the male assembly can fit. Once the male assembly is inserted into the female assembly, the bars can rotate into such a position that the male and female assemblies are connected together. The bars can also be rotated such that the male and female assemblies can be disconnected.

A quick disconnect device for detachably holding a long gun or other elongated emergency tool (EET). The quick disconnect device receives and captures the ball of a ball-and-stem structure that is attached to the EET. The quick disconnect device may allow the EET to rotate about the central axis of the stem, but otherwise prevents relative translational and rotational motion between the EET and the quick disconnect device. The quick disconnect device is especially suitable for mounting to clothing, such as a utility belt or a ballistic vest. the quick disconnect device allows the EET to be inserted without requiring the user to directly manipulate the quick connection device, but requires the user to manipulate some sort of mechanism on the quick connect device in order to release the EET.

A multi-piece umbrella pole that includes first and second pole sections that are assembled into an elongate umbrella pole. The pole sections include an alignment notch and cross pin for facilitating assembly of the two pole sections. An outer sleeve includes a button assembly that can actuate a detent pin for coupling or decoupling the pole sections. The outer sleeve can also include an actuator for a tilt mechanism that angles a canopy portion of the umbrella assembly.

The described embodiments provide a subsea connector that is a quickly deployable and reusable. The subsea connector comprises a male and a female assembly that can be connected and disconnected. The male assembly includes a shaft, a sleeve that surrounds the shaft, and bars that are connected to the shaft and are configured to rotate about one axis. The female assembly includes a receptacle into Which the male assembly can fit. Once the male assembly is inserted into the female assembly, the bars can rotate into such a position that the male and female assemblies are connected together. The bars can also be rotated such that the male and female assemblies can be disconnected.

Quick release mechanisms for auger type cleanout tools are described. The mechanisms enable engagement and disengagement of a handle to an auger without the use of separate retainers or fasteners. Also described are auger type tools and related methods of use utilizing the quick release mechanisms.

A truck-mounted vacuum material handler and quick disconnect for use on a truck with a with a boom for handling plate steel. The handler includes a coupler [32] that has a boom connector [44], a removable carrier [36, 38] with a carrier connector [60], and a base [34] located between the boom connector and the removable carrier. A locking mechanism [66] located in the base is arranged to move between an unlocked position and a locked position relative to the carrier connector. In the unlocked position the carrier connector is removable from the base. In the locked position the carrier connector is secured in the opening and opposing face surfaces [48, 50, 62] of the base and removable carrier are mated to one another. The removable carrier may include a rotator-receiving recess [42] or a rigging hardware eyelet [40] arranged opposite the carrier connector.
