Abstract
An interlocking assembly for a dual hinged door, includes a first latch and second latch each rotatably secured to opposing sides of the door. Each Latch is linked to a first and second interference member respectively, such that positioning the first latch in an open position rotates first interference member in a path of rotation of the second interference member. In that configuration, second interference member is not permitted to rotate and prevents the second latch from opening.

An interlocking assembly for a dual hinged door, comprising:
- a first latch rotatably secured to the door at a first side of the door, the first latch rotatable between a closed position and an open position;
- a second latch rotatably secured to the door at a second side of the door, opposite the first side, the second latch rotatable between a closed position and an open position;
- a first interference member rotatably secured to the door;
- a second interference member rotatably secured to the door, wherein the first interference and the second interference members are positioned adjacent one another;
- a first latch linkage arm rotatably connected to the first latch at a first portion of the first latch linkage arm and rotatably connected to the first interference member at a second portion of the first latch linkage arm spaced apart from the first portion, such that rotation of the first latch from the closed position to the open position moves the first latch linkage arm and causes the first interference member to rotate;
- and
- a second latch linkage arm rotatably connected to the second latch at a first portion of the second latch linkage arm and rotatably connected to the second interference member at a second portion of the second latch linkage arm spaced apart from the first portion, such that rotation of the second latch from the closed position to the open position moves the second latch linkage arm and causes the second interference member to rotate;
- wherein, the first interference member is positioned in a path of rotation of the second interference member, blocking rotation of the second interference member, with the first latch in the open position and the second latch in the closed position.
An assembly for lifting and supporting a door relative to a frame, comprising:
- a first upper hinge pin connected to a top portion of the frame and a first lower hinge pin connected to a bottom portion of the frame,
- a lift pin connected to the door and positioned to extend in a direction forming an angular relationship with a plane formed by the door with the door hinged about the first upper and first lower hinge pins and the door in an opened position;
- a lift pin support member secured to the frame and positioned to engage the lift pin such that the support member provides vertical support of the door and positions the door into a predetermined elevation relative to the frame, with the door in a closed position;
- and
- a door support structure associated with the first lower hinge pin, wherein the door support member extends away from and in angular relationship to a longitudinal axis of the first lower hinge pin and wherein the support structure provides support to the door with the door hinged about the first upper and first lower hinge pins and with the door in an open position.
A handle assembly for a door, comprising:
- a handle rotatable about an axis of rotation of the handle assembly;
- a drive member connected to the handle and rotatable about the axis of rotation;
- a drive pin member connected to the drive member and extending radially from the drive member;
- a drive receiving member rotatably engaged with the drive member and rotatable about the axis of rotation, the drive receiving member defining an opening comprising first and second spaced apart opposing sidewalls, wherein the drive pin member is positioned within the opening and is movable within the opening;
- a cam connected to the drive receiving member and rotatable with the drive receiving member about the axis of rotation;
- and
- a torsion spring positioned about the axis of rotation, the torsion spring having a first arm connected with the handle such that the first arm moves with the handle and a second arm positioned in proximity to the cam such that the second arm moves with the cam;
- wherein the handle assembly is positionable in
- a first closed position, with the handle in a first position, the cam in a first position, the torsion spring in a first unloaded position, and the drive pin member positioned adjacent the first sidewall of the opening;
- an open position, with the handle in a second position, the cam in a second position, the torsion spring in a second unloaded position, and the drive pin member adjacent the first sidewall of the opening;
- and
- a second closed position, with the handle in the first position, the cam in the second position, the torsion spring in a loaded position, and the drive pin member positioned spaced apart from the first sidewall of the opening.
