Abstract:
A system for reducing an effective weight of a horizontally sliding object is disclosed, wherein the system comprises an object such as a door or window retained in a track that allows substantially horizontal movement along a predetermined path. The door has an upper surface with a longitudinal cavity therealong, and a metallic channel is disposed within the longitudinal cavity, where the channel encloses a plurality of permanent magnets. The system also includes an elongate strip coinciding with said predetermined path and positioned adjacent an upper surface of the door. An adjustment mechanism is also provided for releasably adjusting the distance between the magnets and the elongate strip.
Abstract:
A magnetic-push slide cover driving device includes a slide seat having at least one slide guide section, a base seat connected on the slide guide section and reciprocally slidable along the slide guide section, at least one middle magnetic body disposed at a middle section of the base seat, and two movable members respectively pivotally disposed at middle sections of two sides of the slide seat. The movable members respectively have two opposite sides. The middle magnetic body is slidable between the opposite sides along with the base seat. Multiple magnetic bodies are arranged on each of the opposite sides. The magnetic bodies on the same side are such arranged that the poles of the same polarity are directed in the same direction. Accordingly, at a later stage of opening process of a slide cover, the magnetic-push slide cover driving device provides a push aid force for the slide cover.

Abstract:
A door suspension system comprises a horizontally suspended ferromagnetic shaft; a nonmagnetic bracket comprising a bracket cylinder for enclosing a linear bearing and an attached bracket hanger plate for securing a door panel; a nonmagnetic cylindrical linear bearing sized to slide into the bracket cylinder and over the shaft; at least two spaced bores in the upper surface of the bracket cylinder; at least two spaced bores in the upper surface of the cylindrical linear bearing arranged so as to align with the spaced bores in the bracket cylinder; a cylindrical permanent magnet positioned in at least one of the spaced bores of the bracket cylinder; and a ferromagnetic armature to complete the magnetic circuit through the shaft and the magnet or magnets.
Abstract:
An elevator door assembly (20) includes a positioner (30) for controlling an orientation of an elevator door panel (22) during movement between open and closed positions. The positioner (30) biases the door in a direction generally perpendicular to the desired direction of door movement. The disclosed example includes a first positioner member (32) that remains in a fixed position. A second positioner member (34) is supported for movement with the elevator door (22). In disclosed examples, at least one of the positioner members (32, 34) provides a magnetic field that results in the biasing force. In a disclosed example, opposing polarities on permanent magnets are arranged to provide a repulsive force between the positioner members (32, 34), which provides the biasing force on the elevator door.
Abstract:
A safety mechanism for preventing door slamming includes a board and a pivot extending from the board. A rotatable arm is attached at a first end to the pivot. Door arresting wedge (AW) is attached substantially perpendicularly to the second end of the arm. One or more magnets are disposed on the board for attracting the arm. One or more magnets disposed on an edge of the arm, and a matching stopper is used to limit the rotation of the arm.
Abstract:
A hinge including a first hinge member including a first magnetic element; and a second hinge member including a second magnetic element, wherein the first and second hinge members are hingedly mounted to each other. The first and second hinge members are substantially maintained in a retained position via magnetic force between the first and second magnetic elements.
Abstract:
A magnetic gate latch has a multiplicity of permanent magnets arranged on a pair of disks with half of the magnets in mutual attraction and half of the magnets in mutual repulsion. These magnetic forces are used to brake and close a gate or door. One of the disks is made axially movable with respect to the other so as to assume mutual repulsion in one position and mutual attraction in a second position. The movable disk is attached to a gate or door closing member and the other disk is attached to the closing structure post or jamb. Magnetic forces in the repulsion position are used in the invention to reverse the movable disk from a mutual repulsion position to a mutual attraction position.
Abstract:
The present disclosure provides a cable management module having a cover assembly that is secured in the closed position and when manually opened stays in the open position until manually closed. A method of accessing a cable management module is also provided.
Abstract:
A support system includes a frame member and a cover magnetically coupled to one another proximate an edge of the cover and in an aligned state. The cover is rotatable with respect to the frame member without any structural coupling therebetween while the frame member and cover remain substantially in the aligned state. A method of supporting a cover with respect to a frame includes magnetically attracting the cover and frame to each other proximate an edge of the cover.
