Abstract: A clamp includes a bar having top and bottom surfaces, a fixed jaw fixed to the bar, and a movable assembly movable along the bar. The movable assembly includes a movable jaw, an actuator that incrementally moves the movable assembly to apply a clamp force to a clamp load, a release lever to disengage the movable assembly to release a clamp force and permit free sliding of the movable assembly along the bar. The movable assembly may support a bearing surface formed of a low-friction material, positioned to prevent the movable assembly from binding to the bar when a clamp load is released. The release lever may be movable between a position engaging the bar, a position where the release lever disengages the bar, and another position engaging the bar, the third position being opposite the first position with the second position therebetween.

Abstract: A utility knife includes a housing and a slidable blade assembly configured to selectively receive a removable blade in a blade channel thereof and to slide relative to the housing, such that the removable blade is stored within the housing when the slidable blade assembly is in a retracted position, and a portion of the blade extends outwardly from the housing when the slidable blade assembly is in an extended position. The slidable blade assembly comprises a plurality of notch engaging protrusions configured to move to selectively enter the blade channel to engage one or more notches of the removable blade. The housing comprises a blade release actuator configured to move or permit movement of the plurality of notch engaging protrusions out of the blade channel to permit removal of the removable blade from the slidable blade assembly.

Abstract: Certain embodiments of a folding knife are disclosed. In one embodiment, an example knife may include a handle and a blade carrier. The blade carrier may be rotatable about the handle and may include a left and a right cap. A blade may be removably disposed within the blade carrier. The knife may further include a blade release mechanism. In one embodiment, the blade release mechanism may include a compression spring and a lift bar. In another embodiment, the blade release mechanism may further include a wheel. In yet another embodiment, the blade release mechanism may include a leaf spring and a slide bar. When the blade carrier is rotated such that the knife is not in a cutting position, at least a portion of the blade release mechanism is exposed. When the blade release mechanism is activated, the blade may be removed from within the blade carrier.

Abstract: A knife includes a handle, a neck configured to hold a blade, and a lever configured to selectively release the blade from the neck. The lever is coupled to a blade lock arm configured to extend along a side of the blade. A ramped surface pushes the blade lock arm into the blade to press the blade against a side of the neck to clamp the blade to the side of the neck when the blade lock arm is in a blade locked position.

Abstract: A lifting and lowering tool includes a foot configured to be supported on a surface, a bar extending therefrom, and a movable assembly including a housing, a movable platform shaped to support a load that extends from the housing, a lifting actuator configured to incrementally move the movable assembly along the bar away from the foot, a lowering actuator configured to incrementally move the movable assembly along the bar towards the foot, and a release actuator configured to disengage the movable assembly from the bar to allow free movement of the movable assembly along the bar. In embodiments, the movable assembly engages the bar through locking plates that extend through a flange of the movable assembly. In embodiments the release actuator is spaced from the lifting actuator and the lowering actuator to prevent inadvertent actuation of the release actuator. In embodiments a flange of the movable assembly surrounds the bar.

Abstract: A folding knife includes a handle, a blade assembly, a stop member, and a locking arm. The blade assembly is rotatably interconnected with the handle and is moveable between an extended position and a closed position. In the extended position, the locking arm exerts a bias force to wedge a releasable wedge member laterally between the stop member and the blade assembly to inhibit a transition of the folding knife out of the extended position. In the extended position, an unlocking force applied to the locking arm displaces the releasable wedge member from a space between the blade assembly and the stop member to permit the transition of the folding knife out of the extended position.

Abstract: A utility knife comprises a blade carrier movable between retracted, extended and positions. A latch is movable with the blade carrier for locking the blade carrier in position. The blade carrier comprises a locking tab movable between a first position where the locking tab is engaged with the blade and a second position where the locking tab is released from the blade. An actuator moves the locking tab from the first position to the second position when the blade carrier is in the intermediate position and the actuator is moved to the unlocked position. The latch is engageable with a holder when the blade carrier is in the intermediate position. A retention member holds the blade on the plate where the retention member cannot be inserted into a notch on the blade. A blade guide guides the blade between the retention member and the plate.

Abstract: A utility knife comprises a first housing portion carrying a strike plate and a second housing portion movable relative to the first housing portion between a closed position and an open position. The second housing portion carries a locking member. An overlapping locking mechanism locks the first housing portion to the second housing portion in a first direction when the first housing portion is moved relative to the second housing portion in a second direction. The locking member is movable between a first position in which it engages the strike plate to prevent the first housing from moving relative to the second housing in the first direction and a second position in which it does not engage the strike plate and allows the first housing to move relative to the second housing in the first direction.
