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:
An electronic device having a first body, a second body and a hinge is provided. The first body and the second body are pivoted through the hinge. The hinge includes a sleeve, at least one first positioning member, a shaft and a second positioning member. The first positioning member is inserted into the sleeve. A first end of the shaft passes through the sleeve. The second positioning member is inserted into the shaft. The second positioning member and the first positioning member are linked through magnetic force to fix the position of the shaft.
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 standard doorstop is a solid unit that is screwed into the wood baseboard/wall If hit with a vacuum, foot, and or any other objects, it tears away from the baseboard causing damage to the wooden base board/wall. The Break Free Doorstop consists of two pieces a metal mounting base with screw (to mount into baseboard) and a magnet that has been inserted into the doorstop itself to be attached to the mounting base. With this different feature that no solid doorstop can offer, the Break Free Doorstop if hit by a vacuum, foot, or other objects, will break free from the mounting base, causing no damage or repairs to the wooden baseboard/wall. When removed from mounting base it is easily snapped back onto mounting base.
Abstract:
A device having a magnetically rotary cover mechanism is disclosed. Coupled magnets are pivotally mounted on one side of a cover cap of the device, and an attractive or repulsive force between the coupled magnets controls the cover cap to close an opening. The present invention uses the coupled magnets to replace the conventional elastic members for controlling the cover cap to close the opening, thereby simplifying and saving the process and time for assembling the device.
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.
Abstract:
A sliding panel for use in an architectural opening is connected either at its top edge or bottom edge to a carrier that supports the panel with a magnetic system that includes a magnet and a ferrous member. The magnet is positioned on either the carrier or the panel and the ferrous member is on the other of the carrier or the panel with the magnet attracting the ferrous member to connect the panel to the carrier.
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.
Abstract:
A door seal for use with a bi-parting door in which the door panels of the door have supplementary angled leading edges. One leading edge has a triangular cross-section, while the other has a cross-section similar to a parallelogram. To further the reliability of the door seal, a plurality of magnets with corresponding magnet attracting plates may be attached along the leading edges. Alternatively, both leading edges may have at least one magnet aligned with a magnet on the other edge. With the double magnet configuration, the use of multi-pole magnets is necessary. The magnets also help reduce the bounce between the door panels, which may be closed roughly, and increase the force required to separate the door panels when closed.
