    Abstract: A magnetic curtain and a sliding panel formed therefrom are revealed. A magnetic curtain includes an upper portion, a lower portion, a plurality of a plurality of middle portions arranged between the upper portion and the lower portion, and a plurality of magnetic parts disposed on an interface between two adjacent portions of the magnetic curtain. While the magnetic curtain is retracted, the two adjacent middle portions are folded in half in turn to form a curved part respectively. The two adjacent curved parts are away from each other so as to prevent protrusion and extension caused by overlapping of the curved parts. Thus the magnetic curtain has more applications and higher use efficiency.

The ends are removably mounted to opposed walls, below the ceiling without intermediate support. Light weight substantially frameless, translucent/transparent panels are provided to allow uninterrupted passage of light. The top edge of each panel is slidably mounted to a track of the track beam, sliding between the opposed walls on its own track, independently of the other panels. The planar surfaces of the panels are parallel to the track beam and the bottom edges are spaced a distance from the floor. The widths of the panels when added together are at least equal to the length of the track beam and can be positioned along the beam to permit complete closure of the space between the walls or to overlap each other to provide an opening through the space between the walls.

  • Patent number: 8297334
    Abstract: A sliding panel includes multiple connecting/adjacent carrier tracks such as two/three/four carrier tracks while connectors of each carrier track are disposed in opposite directions or at intervals. Thus the multiple connecting/adjacent carrier tracks slide in parallel under the same channel. Moreover, the positions of each connector on top surface of respective carrier track are in alternating arrangement so as to allow runners of multiple connecting/adjacent carrier tracks being mounted inside the same channel simultaneously. The runners of the connecting/adjacent carrier tracks move inside the channel of a rail at the same time and the connecting/adjacent carrier tracks slide in parallel under the same channel. Therefore, the number of channels of the rail is decreased and the amount of material used for producing the rail is reduced. Furthermore, the rail can be designed to have two-step inner and outer rails for adjusting length of the rail.

    Abstract: A curtain system includes several flat panels made of curtain fabric or other planar materials. The top of each flat panel is provided with a horizontal metal, wood or plastic horizontal slat on which the curtain fabric or flat panel hangs in a loose manner. Both ends of the horizontal slat include a fastening device for rollers or sliders. The rollers or sliders at one end of each horizontal slat are guided inside a first common track, while the rollers or sliders located on the other end of each horizontal slat are guided inside a second common track, such that the flat panels can be slid on top of each other. The flat panels extend at an acute angle relative to the first and second common tracks and can be slid on top of each other until the flat panels nearly overlap when the first and second common tracks are mounted parallel to each other, because the fastening device therefore is designed so that the fastening device does not laterally protrude from the horizontal slat or the alignment thereof.

  • Patent number: 5832980
    Abstract: A swinging slide panel construction has panels which can slide relative to one another to open half of an opening, such as a doorway, and then swing together in a break-away mode for full access to the opening. One panel, which is pivotally fixed in the opening, has a support thereon which engages with a track on the other panel to support the same when the two panels are overlapped and swung open. A floating pivot assembly further engages the panels along the bottoms thereof, with the pivot assembly being entirely carried by the panels.

  • Patent number: 5022454
    Abstract: A collapsible double door assembly includes a number of serially connected panels each provided with a pair of inwardly and outwardly deviated pivotal suspension rollers, a horizontal guide rail constituted by an inner rail member and an outer rail member arranged in parallel in close proximity for separately guiding the suspension rollers, and one or two door storage areas extending perpendicularly from the guide rail at one or both ends thereof and formed by separating and independently bending the two rail members with different radiuses of curvature each defining an arc of a quarter of a circle. The radius of curvature of the outer rail member is relatively greater than that of the inner rail member. The distance between the two rail members in a door storage area is slightly smaller than the distance between the two suspension rollers of a panel.

  • Patent number: 4833840
    Abstract: Presented is a two-shell telescopic element of a movable partition containing (holding) two external cover panels on the supporting frame of a wall section, between which, at the upper and/or lower edge, are guided packing strips, and that are extendable out toward the ceiling and/or the floor. An edge-side telescoping part has a vertical edge strut to which are also attached cover panels that overlap the cover panels of the wall section, or that continue in surface-flush fashion. The packing strips have an edge section projecting inwardly between the cover panels of the telescoping part, said edge section being horizontally displaceable together with the telescoping part. In order to achieve an improved noise damping, provided are intermediate panels that engage behind the cover panels of the wall section and of the telescoping part.

  • Patent number: 4033073
    Abstract: A movable member of a grille or shutter is slidable with respect to a stationary member through tongue and groove or other slidable connections, between a fully open and a fully closed position. Both the movable member and the stationary member are provided with corresponding cross bars which are spaced both vertically and equally. Facing upright rails, such as at the center, of the movable member and fixed member are provided with opposed grooves, each for reception of a vertically placed bar magnet. The magnets are placed with their opposite poles facing each other, so that the magnets will attract, rather than repel. Preferably, the closed position of the movable member is the upper position, and the magnets are directly opposite each other in this position.
