OVER-CENTER HOLLOW WALL ANCHOR WITH ENHANCED HOLDING STRENGTH

摘要

2064556 9113263 PCTABS00007 A plastic over-center hollow wall anchor (10) having increased strength without increase in thickness of load bearing members (12a-b) and necessitation of a larger insertion aperture. The bending motion stress on the load bearing arms (12a-b), which causes the weakening or failure mode of the anchor (10) is substantially retarded by the inclusion of a small reinforcing boss (34a-b) across the bending area (300a).
