A hinge for recessed installation between a door frame and a door panel that has first and second housings adapted for recessing in the door frame and an edge of the door panel, a pair of links having ends pivoted in the housings and pivoted together about a vertical axis extending in a vertical direction perpendicular to mutually perpendicular first and second horizontal directions, and two supports in the second housing in which the respective ends of the links are pivoted. A vertical connector body to which the supports are fixed is limitedly vertically movable in the first housing along with the supports and links. Respective pairs of guide faces on the connector body spaced apart in the vertical direction flank each of the supports.

A spiral guiding dual-axis hinge has a fixing base, two mounting brackets, a slider, and a cover. The fixing base includes two installation recesses and a guiding track. The guiding track is located between the two installation recesses; each of the two mounting brackets has an installing part and a mounting part, a top surface of the installing part forms a spiral groove extending obliquely, the two mounting brackets are movably mounted in the two installation recesses. The slider has two wing parts and a guiding part, a guiding pole is formed on the guiding part, and the slider is mounted in the two spiral grooves via the two wing parts; the guiding pole is disposed through the guiding track. The cover covers the fixing base. The two mounting brackets are linked by the slider, thereby flipping movements of the two mounting brackets being synchronized.

A method for installing a multiple axis adjustable pivot bearing assembly, comprising: Installing and adjustment-pivot unit: using bolts or screws to install a pivot floor mount, comprising a pivot floor mount aperture and a slot, to a floor, sliding a pivot square nut with a pivot square nut aperture into the slot such that the pivot square nut aperture is aligned the pivot floor mount aperture, place a pivot cover, comprising a pivot cover aperture, over the pivot floor mount, such that the pivot square nut aperture, the pivot floor mount aperture, and the pivot cover aperture are aligned so as to receive a lower portion of a pivot bolt, installing the pivot bolt into the pivot square nut aperture and through the pivot floor mount aperture and the pivot cover aperture, such that a pivot disk, which is part of or assembled to the pivot bolt, is partially in a recess feature of the pivot cover, installing a height-adjustment nut onto an upper portion of the pivot bolt above the pivot disk, placing a pivot mount block onto the now assembled adjustment-pivot unit; and mounting a door onto the pivot mount block by attaching a door frame onto the pivot mount block.

An adjustment system comprising: a pivot nut comprising a pivot nut aperture feature configured to accept the lower portion of a pivot bolt; a floor mount having a slot in which the pivot nut is slidingly engaged so as to have, e.g., simultaneous movement including forward-backward, side-to-side and rotational and axial articulation, the floor mount having a floor mount aperture that aligns with the pivot nut aperture; and a cover configured to mount over the floor mount and engage with the pivot nut so as to move with the pivot nut.

A hinge for a panel or window has a frame subassembly having a frame leaf mountable on a fixed frame and a substantially cylindrical bushing fixed to the leaf and centered on an axis, a panel subassembly having a leaf mountable on the panel of the door and a flange fixed to the leaf, and a hinge-pin assembly pivotally interconnecting the frame and panel subassemblies and having a hinge pin rotatable in the bushing and a part fixed to an end of the hinge pin and having a seat slidably receiving the flange. An adjuster moves the flange in the seat in the hinge-pin subassembly in a transverse direction normal to the axis of the hinge-pin subassembly. A clamping block is slidable in the transverse direction in the part of the hinge-pin assembly. A connecting element secures the clamping block to the hinge-pin subassembly and can slide in the flange.

A sliding door assembly. The sliding door assembly includes a door frame having an upper track and a lower track. A swing door is mounted to the door frame and multiple sliding doors are also mounted to the frame. The sliding doors slide when they are in a sliding configuration and also swing open and closed when they are in a swing configuration. Each sliding door includes an electronic door control switch, an upper track shoot bolt linear actuator for extending and retracting a shoot bolt, a upper track hinge pin linear actuator for extending and retracting a hinge pin, a lower track lift wheel linear actuator for extending and retracting a lift wheel assembly, a rigidly attached hinge wheel assembly having rotatably connected hinge wheels, and a power supply for providing power to the electronic door control switch, the shoot bolt linear actuator, the hinge pin linear actuator and the lift wheel linear actuator. When the upper track shoot bolt and the lower track lift wheel assembly are extended and the upper hinge pin is retracted, then the sliding door assembly is in a sliding configuration. When the upper track shoot bolt and lower track lift wheel assembly are retracted and the upper hinge pin is extended, then the sliding door assembly is a swing configuration.

A hinge system for use with frameless glass shower doors is presented. The hinge system is self-closing or self-centering and includes angular adjustability in two planes to aid in door alignment. The door hinge system further includes drop-in pivot pins which aid in shower door installation and also includes adapter plates that allow for installation to glass walls and further includes adapter plates that allow door panels equipped with the hinge system to be installed as fixed panels at various angles.
