A hinge lock comprising an rectangular elongate body having dimensions including a height, width and depth formed by a rear planar rectangular wall joining two opposing planar rectangular walls along opposing long edges and a top enclosed end. An open front channel is formed and an open bottom end are formed by the joined planar walls and the top, thereby enabling the elongate body to be slid into position over a pivot portion connecting two wall plates of a closed hinge assembly.

A security door hinge assembly is provided, comprising a door frame structure, having at least a head member, a first jamb member and a second jamb member, and at least one door leaf. The door leaf further comprises a leaf frame structure, having at least a top rail member, a bottom rail member, a hinge stile member and a lock stile member; an inner leaf panel, mounted to a first side of said leaf frame structure and extending past said hinge stile member, so as to form an inner leaf flange; an outer leaf panel, mounted to a second side of said leaf frame structure, opposite said first side, and extending past said hinge stile member, so as to form an outer leaf flange, and wherein, in use, said door leaf is operable between a first closed position and a second open position. The security door hinge assembly further comprises a hinge chamber positioned between said first jamb member and said hinge stile; a hinge-mount bracket, coupled to said first jamb member; a hinge mechanism, having at least one pivot axis and which is located within said open hinge chamber and adapted to pivotally mount said door leaf to said hinge-mount bracket, and wherein, in said first closed position, said inner leaf flange is in an exteriorly overlapping engagement with at least a portion of said hinge mount bracket, so as to prevent access to said hinge mechanism.

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.

A door hinge has a first leaf assembly, a second leaf assembly, and a link assembly connected to the leaf assemblies for pivoting of the second assembly on the first assembly. An adjuster in the first leaf assembly can displace the link assembly relative to the first leaf assembly and thereby adjust a position of the door in the frame. The adjuster has an adjusting element projecting from the first leaf assembly in the closed position. The second leaf assembly is formed with a recess in which the projecting adjuster engages in the closed position.

A hinge assembly including a flat plate and a bent plate is provided. The flat plate includes a first slot extending at least partially along a width of the flat plate and disposed substantially perpendicular with respect to a central axis of the flat plate. The bent plate includes a first portion, a second portion, and a third portion. The second portion includes a second slot extending at least partially along a width of the bent plate and disposed substantially perpendicular with respect to a central axis of the bent plate. The second slot is adapted to interconnect with respect to the first slot to pivotally move the hinge assembly between an open position and a close position. In the open position, the first portion of the bent plate is adapted to contact a first half section on a first side of the flat plate.

A security door hinge assembly is provided, comprising a door frame structure, having at least a head member, a first jamb member and a second jamb member, and at least one door leaf. The door leaf further comprises a leaf frame structure, having at least a top rail member, a bottom rail member, a hinge stile member and a lock stile member; an inner leaf panel, mounted to a first side of said leaf frame structure and extending past said hinge stile member, so as to form an inner leaf flange; an outer leaf panel, mounted to a second side of said leaf frame structure, opposite said first side, and extending past said hinge stile member, so as to form an outer leaf flange, and wherein, in use, said door leaf is operable between a first closed position and a second open position. The security door hinge assembly further comprises a hinge chamber positioned between said first jamb member and said hinge stile; a hinge-mount bracket, coupled to said first jamb member; a hinge mechanism, having at least one pivot axis and which is located within said open hinge chamber and adapted to pivotally mount said door leaf to said hinge-mount bracket, and wherein, in said first closed position, said inner leaf flange is in an exteriorly overlapping engagement with at least a portion of said hinge mount bracket, so as to prevent access to said hinge mechanism.

A hinge assembly including a flat plate and a bent plate is provided. The flat plate includes a first slot extending at least partially along a width of the flat plate and disposed substantially perpendicular with respect to a central axis of the flat plate. The bent plate includes a first portion, a second portion, and a third portion. The second portion includes a second slot extending at least partially along a width of the bent plate and disposed substantially perpendicular with respect to a central axis of the bent plate. The second slot is adapted to interconnect with respect to the first slot to pivotally move the hinge assembly between an open position and a close position. In the open position, the first portion of the bent plate is adapted to contact a first half section on a first side of the flat plate.

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.
