Abstract:
A partition door system includes a partition door, a stile, and a closing mechanism coupling the partition door to the stile, such that the closing mechanism provides a force for closing the door relative to the stile. A first magnet is at the partition door proximate the stile, and a second magnet is at the stile proximate the door. A partition door including a magnet, a stile including a magnet and a method of operating the same are also provided.
Abstract:
A door system suitable for installation in data centers to limit airflow to and from aisles between rows of equipment cabinets has a door assembly with a door panel and a plurality of vertically spaced hinge assemblies having powerful permanent magnets manually movable between connected and disconnected positions, enabling the door assembly to be aligned and positioned on the side wall panel of an equipment cabinet and then removably mounted in place by engagement of the magnets. Each magnet can be mounted in a rotatable threaded magnet carriers received in a threaded recesses in the hinge assembly and rotation of the magnet carrier is operable to move the magnet into the connected and disconnected positions. The hinge assemblies also include registration tabs that engage slots in the cabinet for proper alignment and orientation of the door system.
Abstract:
Door stops are generally discussed herein for stopping door knobs or other door hardware from slamming against a wall with particular discussions on door stops having dampening means. Aspects of the door stop assemblies discussed herein include the use of a helical coil spring spacer for delimiting movement of a door and either a pliable insert or an outer sheath or both for dampening the spring when the same is impacted. A combination magnet and magnetically attractable plate or two magnets with opposite magnetic poles may be used to temporary secure a door in a fixed position.
Abstract:
A door opening/closing device for use in a vehicle is provided with a driving member. The driving member has a permanent-magnet motor provided with two terminals and an output member, which is rotationally driven by the permanent-magnet motor. The driving member is mounted on either a vehicle body or a vehicle door and is coupled to the other via the output member. As the output member rotates, the vehicle door opens or closes. The door opening/closing device is also provided with a switching device configured to switch the permanent-magnet motor between an energizable state, in which the permanent-magnet motor can receive electricity through the two terminals, and a brake state, in which the terminals are short-circuited. The switching device switches the permanent-magnet motor into the brake state when the vehicle door is in any position other than the fully closed position.
Abstract:
A locking hinge design relies on a mechanically-actuated magnetic clutch to selectively disengage first and second gears respectively coupled to first and second members and thereby selectively enable relative rotation between the first and second members about an axis of rotation. The mechanically-actuated magnetic clutch includes first and second magnetic members disposed in an opposing relationship, such that permanent magnets respectively disposed in each magnetic member may be placed into either a mutually attractive or mutually repellant relationship in response to relative movement therebetween. One of the magnetic members is coupled to one of the gears to move the gear along the axis of rotation and thereby selectively disengage or engage the gear from or with the other gear such that the gears are selectively engaged in response to mechanical movement of the magnetic members.
Abstract:
A sliding panel structure. The sliding panel structure includes a frame having an upper support track and a lower guide rail. At least one sliding panel is connected between the upper support track and the lower guide rail. The sliding panel includes a sliding panel pivot axis and an extension for riding in the lower guide rail. The extension prevents undesired pivoting of the sliding panel about the sliding panel pivot axis. A mutual attraction device is connected between the sliding panel and the frame with a first mutual attraction part connected to the frame and the second mutual attraction part connected to the sliding panel. A fulcrum is utilized for tilting the sliding panel whenever the first mutual attraction part engages the second mutual attraction part.

A mutual attraction device is connected between the sliding panel and the frame with a first mutual attraction part connected to the frame and the second mutual attraction part connected to the sliding panel. A fulcrum is utilized for tilting the sliding panel whenever the first mutual attraction part engages the second mutual attraction part. The tilting of the sliding panel causes the extension to disengage the lower guide rail which allows the sliding panel to pivot about the sliding panel pivot axis. In a preferred embodiment the sliding panel structure includes at least one stationary pivoting panel. In another preferred embodiment the sliding panel is a plurality of sliding panels. In another preferred embodiment the sliding panel is a sliding door. In another preferred embodiment the sliding panel is a sliding window. In another preferred embodiment the mutual attraction device is utilizes magnetic force so that a magnet connected to the sliding panel is attracted to a magnet connected to the frame.
Abstract:
A system for reducing an effective weight of a horizontally sliding object, wherein the object such as a door or window is retained in a track that allows substantially horizontal movement along a predetermined path. The door has an upper surface with a longitudinal cavity therealong, a metallic channel is disposed within the longitudinal cavity, and the channel receives a plurality of permanent magnets. The system also includes an elongate strip coinciding with the predetermined path and positioned adjacent the 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 system and method for detecting damage to a door system by detecting the presence or absence of a magnetic source attached to the door system for stopping motion or reversing motion of the door to prevent any further damage to the door system. For example, a roll-up type door may be damaged by a vehicle and pulled from its vertical support guides; detecting this event causes stopping of any motion of the door, such as opening or closing the door.
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.
