FLUSH BOLT
An adjustable flush bolt mechanism for mounting on a free edge of a door for providing latch bolt engagement between the door and a door frame, ceiling or floor, when the mechanism is in an engaged condition, the mechanism including: i) a housing being mountable within the free edge of the door; ii) a latch bolt comprising a proximal end and a distal end; iii) a carrier member which is adapted to engage with the proximal end of the latch bolt; iv) a crank being pivotally connected to the housing and comprising a first arm and a second arm; v) a link member which is connectable to a proximal end of the carrier member, and a crank end which is connectable to the first arm of the crank; and vi) an activator tongue comprising a strike end and a cam end and being movable within the housing, wherein, pushing of the activator tongue substantially into the housing causes the mechanism to adopt an engaged condition, wherein the cam end of the activator tongue acts upon the second arm of the crank, whereby the crank rotates about its pivot and causes the first arm to move, whereby the link member connectable thereto urges against the carrier member and causes the latch bolt to extend from the door.
