Abstract
An anti-ligature door system that utilizes an anti-ligature hinge to operatively couple the door to the door frame. The anti-ligature hinge has an assembled leaf portion formed from a pair of leaves that are operatively coupled together using one or more pins. The anti-ligature cap that is operatively coupled to the leaf portion has a body with one or more projections extending therefrom. The one or more projections may comprise a leaf projection that is configured to be located between the first leaf and the second leaf and operatively coupled to the first leaf or the second leaf. The one or more projections may further comprise a knuckle projection that is configured to be operatively coupled to a knuckle of the first leaf or the second leaf, such as by being inserted into a knuckle aperture formed by the inner surface of the knuckle.
