  • Patent number: 6196034
    Abstract: A latch assembly incorporates a pair of overlapping tubular guard projections respectively secured to a pair of opposing structural members, at least one of which is disposed on a slidable partition. As the projections are tubular, the projections isolate the enclosed area within the projections from all sides. Moreover, as one projection overlaps the other, no gaps are present that could otherwise permit access to the enclosed area within the projections. As such, whenever a latch member projects through the enclosed area within the overlapping projections, the latch member is substantially protected from unauthorized tampering.
