Abstract
A hinge for supporting a heavy door on a support. The hinge has a main block mounted on the support and a pair of parallel plates mounted on the door. An extender link and a rotation control link are each pivotally mounted to the main block and between the parallel plates. When the door is in the fully closed position, the main block supports the upper parallel plate. When the door is in the fully opened position, the extender link is interlocked with the rotation control link and supports the door. A compressible seal is formed between the door and the support by a sealant disposed about the perimeter of the door. The compressible seal is not exposed to shear forces.
Claims19
A hinge for supporting a heavy door or panel on a support means, the hinge comprising:
- a main block mounted on the support means, the main block having a front, a back, an upper wall and an opposite lower wall;
- an extender link having a first end pivotally connected between the upper wall and the lower wall of the main block and a second end extending outwardly from the main block;
- a rotation control link having a first end pivotally connected between the upper wall and the lower wall of the main block and a second end extending outwardly from the main block;
- an upper plate and a lower plate mounted parallel to one another on the door or panel, each parallel plate having a first end near a rear vertical edge of the door or panel, the respective second ends of each link being pivotally connected to the respective first ends of the parallel plates;
- wherein, when the door or panel is pivotally moved to a closed position substantially parallel and adjacent to the support means, the main block is received beneath the upper plate and above the lower plate, thereby substantially supporting the door or panel;
- and
- wherein, when the door or panel is pivotally moved to a fully open position, the door or panel and the parallel plates mounted thereon are approximately perpendicular to the support means, the door or panel being substantially supported by the interlocked extender link and the rotation control link.
