Abstract
The shelf support assembly includes an integral disk and shank with an aperture through the longitudinal axis thereof. A screw passes through the aperture. Flexible arms are formed around an opening in the disk formed by the aperture. The flexible arms engage the threads of screw during a pre-assembled position. However, the flexible arms deflect in response to axial urging of the screw thereby allowing the screw to move axially during the initial insertion of the screw into the pre-assembled position. This deflection further occurs in response to subsequent axial adjustment of the screw prior to installation, in response to the dropping of the shelf support assembly in the pre-assembled position thereby allowing the flexible arms to absorb a portion of the energy of the fall, and in response to the installation of the shelf support assembly into the mounting panel.
