ABSTRACT:
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.
