Description

FIG. 1 is a perspective view from the left of an “anti-ligature lock” showing our new design. The lock is shown with the handle in an upward position corresponding to an extended latchbolt.
FIG. 2 is a front elevational view thereof. The lock is shown with the handle in an upward position corresponding to an extended latchbolt.
FIG. 3 is also a front elevational view as seen in FIG. 2 except that the lock is shown with the handle partially pivoted down corresponding to a partially retracted latchbolt.
FIG. 4 is a left side elevational view thereof.
FIG. 5 is a right side elevational view thereof.
FIG. 6 is a top side elevational view thereof; and,
FIG. 7 is a bottom side elevational view thereof.
The back surface of the anti-ligature lock is substantially flat for mounting against a door and is not shown. The back surface of the anti-ligature lock forms no part of the claimed design.
The broken lines in the illustrations show environmental structure comprising a door and latchbolt and are not a part of the design sought to be patented.
