Abstract
An anti-ligature handle and escutcheon mechanism mountable on a door for operating a lock for securing the door. The mechanism comprises a handle movable between open and closed positions, the handle having a smoothly curved outer surface to prevent the attachment of a ligature thereto and comprising a pivot at a first end for rotating the handle between the open and closed positions to operate the lock. An escutcheon fixed relative to a backing plate is oriented for mounting parallel to the door when the mechanism is mounted on an outer surface of the door, wherein the escutcheon surrounds the handle and defines a recessed area within which the handle pivots. The handle further has a second end including a guide which is trapped beneath and slides along an arcuate edge of the recessed area of the escutcheon to maintain flush contact between a mating surface of the handle and the backing plate to prevent ligatures from being inserted therebetween as the handle rotates to operate the lock. The mechanism further comprises a mounting plate disposed between the backing plate and an inner surface of the door when the mechanism is mounted on the outer surface of the door, the mounting plate fixed relative to the escutcheon and backing plate.
