Flush bolt with fliplock
First Claim
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 first end and a second end, the first end hingedly coupled to the housing within the cavity; 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, 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.

Abstract
A flush bolt with improved travel is disclosed. The flush bolt is composed of a housing with a slotted longitudinal cavity in its face and a bore at least partially through one end of the housing and passing far enough through the housing as to engage with the slot. A bolt is within the bore and a coupling lever is rotatably coupled to a bolt at one end and to a slotted actuator arm at a centrally located point. The slotted actuator arm is coupled at one end to the housing at a point centrally located within the longitudinal cavity so that when pivoted, the slotted actuator arm transfers its pivotal movement to angular movement in the coupling lever and, in turn, into linear motion of the bolt.
