A double action closure mechanism operable with the thumb and forefinger of one hand, comprises a rigid body, such as a forged hook, having a first end, a second end forming a curved nose, and a shank extending between the ends, the shank defining a front side facing the nose, and a back side facing away from the nose. A closure frame is pivotally connected to the front side of the shank and defines a locking corner at the back side of the shank, a latching corner adjacent the nose of the rigid body, and an actuating corner at the front side of the shank, adjacent the pivotal connection. The latching corner includes a latching surface adapted to close against the nose when the frame is pivoted about the shank into a closed position, and to move away from the nose toward the shank when the frame is pivoted about the shank into an open position. A spring is connected between the front side of the shank and the frame, for urging the frame into a normally closed position. A locking member is supported within the locking corner of the frame and engagable with the back side of the shank when the frame is in the closed position, to prevent the frame from pivoting out of the closed position. An actuating member at the actuating corner is supported within the frame for movement toward the locking corner. This movement is effective to disengage the locking member from the back side of the shank, independently of the pivotal movement of the frame relative to the shank.

A double action closure mechanism operable with the thumb and forefinger of one hand, comprising: a rigid body having a first end, a second end forming a curved nose, and a shank extending between the ends, the shank defining a front side facing the nose and a back side facing away from the nose, the back side of the shank including a recess; a closure frame pivotally connected to the front side of the shank and defining a locking corner at the back side of the shank, a latching corner adjacent the nose of the rigid body, and an actuating corner at the front side of the shank adjacent the pivotal connection, the latching corner including a latching surface adapted to closed against the nose when the frame is pivoted about the shank into a closed position and to move away from the nose toward the shank when the frame is pivoted about the shank into an open position; means between the front side of the shank and the frame, for biasing the frame into the closed position; locking means supported within the locking corner of the frame and engagable with the back side of the shank when the frame is in the closed position, to prevent the frame from pivoting out of the closed position, the locking means including a locking pin slidable into and out of the recess, socket means within the locking corner of the frame for slidingly supporting the locking pin, and means for biasing the locking pin into a locked position partly in the socket and partly in the shank recess; actuating means accessible at the actuating corner and supported within the frame for movement toward the locking corner, said movement being effective to disengage the locking means from the back side of the shank, independent of the pivotable movement of the frame relative to the shank; whereby the frame can be pivoted about the shank from the closed to the open position, by first urging the actuating means toward the locking corner with the thumb to disengage the locking means from the shank, and then pulling the locking means from the shank, and then pulling the locking corner toward the shank first end with the forefinger to pivot the frame.
