A hinge assembly includes a hinge plate having a pin-receiving portion at a first end defining a passageway along the first end, and including a plurality of mounting holes. A pivot arm has a pin-receiving portion at a first end defining a passageway that is substantially coaxial with the passageway of the hinge plate. A hinge pin is disposed in the passageways to pivotally couple the pivot arm to the hinge plate. The pivot arm is pivotable between a closed position and an open position. The pivot arm includes a domed portion forming a cavity positioned to overlie one of the mounting holes in the hinge plate when the pivot arm is in the closed position.

A door security device for an in-swing door includes a mounting plate secured to the door jamb adjacent the door outside edge, a hinge pin assembly supported by the mounting plate proximate the door outside edge, a locking swing plate secured to the hinge pin assembly for pivotal movement between unlocked and locked angular positions in relation to the hinge pin vertical axis, the locking swing plate biased by force of gravity to a lowermost position, and the mounting plate having a first receiver wall defining the lowermost position of the locking swing plate in the locked position perpendicular to a first rear surface of the mounting plate and defining the uppermost position of the locking swing plate in the unlocked position away from the locked angular position.

A security door mounting arrangement for a safe (10) including a substantially rectangular-shaped block for the body (20), having a base (22), a rear wall (in the direction (23), a pair of side walls (24) and a top (25), all defining the cavity (21), and an opening (in the direction (26)) defined by a door jamb (27). A hinged door (40) includes a locking assembly (60), including a crank assembly (62). The crank assembly (62) includes a central crank (63) comprising a disc plate substantially parallel-planar with a main panel of the door (40). The crank (63) is operable by a handle installed on the front face of the door (40). The handle and the central crank are rotatable together coaxially and about a common axis A.

The present disclosure concerns a closure system comprising a closure hinged to a fame by a hinge device that permits transition of the closure between open and closed positions by a combined linear movement and rotational displacement.
