ABSTRACT:
An adjustable backset latch which may also function as a spring latch includes a front case and a rear case telescopically movable relative to the front case. There is a bolt axially movable within the front case and a spring biases the bolt outwardly from the front case. A plunger is positioned adjacent the bolt and axially movable within the front case. A spring biases the plunger outwardly from the front case. A swivel is rotatable in the rear case and there is a retractor movable within the front and rear cases and in engagement with the bolt. A pinion connects the retractor to the swivel such that rotation of the swivel moves the retractor and bolt. Backset, the distance between the axis of rotation of the swivel and the front of the faceplate is adjustable. A flexible backset latching element is mounted on the interior of the rear case and has an outwardly extending projection which passes through an opening in the rear case. There are a pair of longitudinally spaced openings in the front case, with each front case opening being movable into alignment with the rear case opening and when so aligned the flexible backset latching element projection extends through both the rear case opening and the aligned front case opening to define a backset distance between the axis of rotation of the swivel and the front of the faceplate.
