Abstract:
1. A flush bolt adapted for mounting on a door and operation between an engaged position with a securing surface and a disengaged position, the flush bolt comprising: a housing, the housing having a face externally exposed when the housing is affixed to an edge of the door, the housing having an attachment means for affixing the housing to the door, the housing having a longitudinal bore starting at a first end of the housing, the longitudinal bore parallel to the face of the housing and the longitudinal bore extending through at least a portion of the housing; a bolt slideably adapted within the longitudinal bore, the bolt having an engagement end for engaging with the securing surface and a distal connection end; a cavity in the face of the housing; a slotted actuator arm having a distal end and a second end, the distal end hingedly coupled to the housing within the cavity, a slot of the slotted actuator arm extending from the distal end longitudinally to a point between a mid-point of the slotted actuator arm and the second end of the slotted actuator arm; and a coupling lever passing through the slotted actuator arm, the coupling lever passing through a longitudinal slot in the cavity, the coupling lever rotatably coupled to the slotted actuator arm at approximately the mid-point of the slotted actuator arm, an end of the coupling lever rotatably coupled to the distal connection end of the bolt, whereas rotation of the slotted actuator arm transfers angular movement to the coupling lever and results in a linear movement of the bolt;
