  • Patent number: 5508902
    Abstract: First and second parts of a metal reflector of a light fixture are interconnected by tab-and-slot arrangements. The first part has hook-shaped tabs and an abutment tab projecting from an edge thereof. The second part has slots for receiving respective tabs. When the parts are converged in a first direction to cause the hook-shaped tabs to enter their respective slots, the abutment tab is offset from its respective slot, whereupon the abutment tab elastically deforms the second part such that the abutment tab and second part are biased toward one another while the deformation exists. When the parts are subsequently moved in a second direction (perpendicular to the first direction) to cause the hook-shaped projections to move within their slots and capture the second part, the abutment tab becomes aligned with, and enters, its slot.
