Abstract:
A sliding door for selectively opening and closing an opening is disclosed. The door is comprised of a door panel having a top, a bottom, a leading edge and a trailing edge. The door panel translates laterally relative to the opening between a closed position and an open position. The door has a guide, a guide follower, and a reset member. The guide is mounted to a mounting surface located between the upper and lower extent of the opening, and comprises a first end disposed proximate the opening and a second end opposite the first end. The guide follower is attached to the door panel and disposed in operable engagement with the guide. The reset member is disposed proximate the second end of the guide. The reset member has a surface that is angularly oriented to facilitate operable engagement and alignment of the guide follower with the guide.
Abstract:
A hinge apparatus having a barrel region that include at least two magnets. The magnets are positioned within the barrel region to generate a continuously repulsive force relative to each other such that the weight of the door is supported at least partially by the magnetic forces generated by the magnets.
Abstract:
An elevator door mover device (40) includes a threaded ferromagnetic shaft (42). Magnetic movers (48) associated with doors (26) generate magnetic fields that cause the doors to move responsive to rotation of the shaft (42). In one example, a controller (46) controls a speed of a motor (44) that drives the shaft (42). The controller (46) in some examples also selectively controls the strength of the magnetic fields of the movers, which provides more customizable door performance.
Abstract:
A door holder door stop and method of installing that uses magnetic force to hold a door in an open position adjacent an interior wall. The door holder door stop includes an elongated arm having a first end and a second end, a screw disposed at the second end, the screw to fixedly secure the arm to the wall. A magnetic surface is disposed on a magnetic head, the magnetic head attached at the first end of the arm. The door holder door stop further includes a metal plate having a first side and a second side. The second side having an adhesive surface to fixedly secure the plate to the door. When the door is opened and moved to towards the wall, the first side of the metal plate is attracted to the metal surface of the arm, and therefore the door is retained in the open position.
Abstract:
An elevator door assembly includes a rail and at least one roller that rolls along the rail to move a door between opened and closed positions, for example. A resilient track is provided on the rail that facilitates more efficient roller movement and increases the longevity of the assembly. In one example, the resilient track includes several pieces of flexible material that are snapped in place onto the rail. In another example, the flexible track is supported on the rail using a spray coating technique.
Abstract:
A door or hatch capable of moving between an open and closed position and normally biased to revert to one of those positions is retained by a manually operable retaining means. A release means is provided to automatically release the door or hatch to thereby allow it to return to its biased position, automatically. The release means is operable in normal ambient temperature for automatically releasing the door or hatch and operable under fire conditions for automatically releasing the door or hatch.
Abstract:
A door stop and holder has a magnet mounted on a door and a metallic disc mounted on the end of a coil spring which projects from a wall. Both the magnet and the disc are adapted for slight free movement for self alignment and enhanced grasping and long term holding action by the magnet.

Abstract:
The invention relates to a garage door drive comprising a guide rail for the receiving of a drive means and a drive unit arranged in a housing, with the guide rail being releasably connectable to the housing. In accordance with the invention, the guide rail can be fixed to the housing by latching tongues formed on it and latchable into corresponding molded elements arranged on the housing or by at least one C-shaped holding clip engaging around the guide rail and latchable into corresponding molded elements arranged at the housing.
Abstract:
The present invention relates to a hold-open apparatus for controlling the position of a door, preferably a screen door or storm door. The apparatus is used in conjunction with a piston assembly and can maintain a door in a predetermined open position, such as about 45° to about 100° in relation to a closed position. In a preferred embodiment, the apparatus can automatically lock and/or unlock when the door reaches predetermined positions. The apparatus advantageously can be retrofitted to existing door assemblies.
