Patent attributes
An anti-ligature door latch assembly comprises a door latch, an escutcheon, and an anti-ligature handle mounted to the escutcheon for movement along a guided linear path between a default non-operative position and an operative latch-retracting position. The anti-ligature handle includes a shroud that maintains contact with the escutcheon regardless of the position of the handle on the escutcheon and covers a linear slot in the escutcheon along which the handle rides. The anti-ligature door latch assembly is suitable for both mortise and tubular latch assemblies. The escutcheon and a back plate mounted to the door surface houses an activator plate that moves linearly with the handle. The activator plate has a cam surface that, when in the operative latch-retraction position, contacts a cooperating part of a spindle-mounted rotary hub, causing the spindle to rotate and retract the latch.
