A hook reciprocable between a recessed inoperative position and an exposed operative position and comprises a housing formed with a cylindrical side wall which has an open exterior end and an interior end with a circular end cap enclosing the side wall at the interior end to define a cylindrical opening therebetween. A flange extends radially outwardly from the open exterior end. A pair of apertures are formed through a central axial extent of the side wall at diametrically opposed locations and exteriorly facing marking notches formed on the exterior surface of the flange in circumferential alignment with the apertures. A support is positioned within the opening of the housing. The support has an interior extent in a cylindrical configuration and a forward extent with a hook. The cylindrical extent includes a pair of recesses. A pair of leaf springs each have a forward end, a rearward end and a central portion therebetween. The forward end is secured to the exterior surface of the housing. The rearward end is movable radially with respect to its associated aperture. The central portion has a forward extent and a rearward extent and extends into the housing. A coil spring is located between the forward surface of the end cap and the rearward surface of the housing and urges the housing to the deployed orientation.

An improved hook assembly reciprocable between a recessed inoperative position and an exposed operative position comprising, in combination: a housing formed with a cylindrical side wall having an open exterior end and in interior end with a circular end cap enclosing the side wall at the interior end to define a cylindrical opening therebetween, a flange extending radially outwardly from the open exterior end, a pair of apertures formed through a central axial extent of the side wall at diametrically opposed locations and exteriorly facing marking notches formed on the exterior surface of the flange in circumferential alignment with the apertures; a support positionable within the opening of the housing, the support having an interior extent in a cylindrical configuration and a forward extent with a hook, the cylindrical extent including a pair of recesses at an intermediate axial extent defining a rearward portion inwardly thereof and a forward portion outwardly thereof, each recess having an angled forward ramp and a rearward radial edge; a pair of leaf springs each having a forward end, a rearward end and a central portion therebetween, the forward end being secured to the exterior surface of the housing axially aligned on opposite sides of the housing, the rearward end being movable radially with respect to its associated aperture, the central portion having a forward extent and a rearward extent and extending into the housing, the central portion of each spring being configured with the rearward extent extending axially transverse to the longitudinal axis of the housing and support, the forward extent of each central portion being formed at an angle generally parallel with the ramp, the housing with its apertures and springs being sized and positioned with respect to the support and its recesses whereby when the hook is in the forward operative position the central portions of the springs are located within the recesses to effect a locking relationship therebetween but when the support is depressed the support will move radially outwardly by the force of the ramp of the support against the forward extent of the spring to effect a disengagement therebetween whereupon rotation of the support will allow the support to move the hook to the operative position; a coil spring located between the end cap and the rearward surface of the support urging the support to the exposed operative orientation; the hook being formed as a circular loop and further including an arcuate extent within the circular loop for functioning as a rope gripper with barbs on the interior surface of the arcuate extent; and further including a cutting blade formed on an exterior portion of the loop with a clip pivotally mounted with respect thereto for shielding the blade for safety purposes.
