ABSTRACT:
A hidden hinge mechanism is provided for mounting a door to a jamb in a door frame. The hinge mechanism may be formed of one or more pairs of body elements, sleeves, and a slide element. The body elements are formed as cylindrical barrels with arcuate cavities defined therewithin. These cavities have a circular curvature centered on a vertical axis of rotation that lies beyond the door and frame. The sleeve elements are hollow and also formed as arcuate structures that are mounted to move within the cavities in the cylindrical body elements in reciprocal fashion relative thereto. The sleeves move between closed positions retracted completely into the body elements and extended positions projecting therefrom. The arcuate slide has opposing ends that are respectively mounted to the sleeve elements in telescoping fashion. The slide moves between an extreme open position withdrawn from the sleeves and an extreme closed position encapsulated within them. The slide, the sleeves, and the cavities within the cylindrical barrels all have an arcuate configuration with a circular curvature centered on the axis of rotation of the door relative to the frame. There are two telescoping actions in the structure of the hidden door hinge. First, there is a telescoping action of the slide within the sleeves. There is a second telescoping action of the sleeves within the cavities in the hinge cylinder barrels. When the door is closed, the door mounting edge of the door lies flush against the door jamb and all of the components of the hinge are hidden from view.
