Definitions

  • One type of track-carried horizontally movable wall partition system of background interest to the present invention is an accordion door system offered by Moderco Partitions Inc., in which a multiple pantograph construction is suspended from rollers on tracks in the ceiling and alternative vertically oriented panels of flexible material are secured to spaced portions of the pantograph structure so that, as the pantograph is expanded laterally, the partition closes providing a finished corrugated-like appearance.
  • the pantograph structure expands longitudinally, in a direction parallel to the axis formed by the aligned intersection points of the beams, and contracts in a similar fashion.
  • the pantograph structure in engineering applications, is useful because it causes forces applied longitudinally, in the direction of expansion and contraction of the structure, to be transmitted evenly throughout all of the beams of the structure.
  • all of the apexes of the diamonds formed by the points of intersection of the beams, as the structure is contracted will arrive at their final, fully contracted position at the same time, meaning that the apexes of diamonds at the outer end, which are moving towards the other end during contraction, will move at a much greater speed than the apexes of the diamonds at the inner end.
  • German Patent No. 1,784,874 of Tokyo Blind Kogyo Co., Ltd., et al which describes and illustrates a wall which is based on a central, pantograph or scissors linkage over which another scissors linkage structure is mounted, a woven fabric or other such flexible covering then covering the double scissors linkage on both sides.
  • German Offenlegungsschrift DE 3438848 Al of Kaczikowski describes and illustrates a ceiling hung collapsible wall partition made of a plurality of rigid panels aligned end to end, with confronting ends of adjacent panels secured together by means of a flexible material. Adjacent panels are intended to fold over on top of each other, one panel at a time, from the ground up, as the partition is raised.
  • the present invention relates to an improvment for a wall partition which is vertically upwardly movable into storage position and vertically downwardly movable to form a wall.
  • the partition comprises a support frame of similarly constructed, vertically aligned trains of elongated members.
  • the trains are spaced horizontally over a predetermined distance.
  • the members of each train are arranged in a single pantograph construction to form a single row of similar sized vertically stacked diamonds aligned parallel to a desired wall line of the wall.
  • the trains are expandable to a lower, wall-forming position and upwardly liftable to an upper, raised storage position.
  • the diamonds of the trains from one train to the next form horizontal rows of diamonds, the diamonds in each horizontal row being of similar size and shape.
  • each train similar pairs of elongated members intersect and are secured pivotally together centrally between their ends to form adjoining vertically disposed apexes of adjacent diamonds.
  • corresponding ends of these pairs of intersecting members pivotally connect to the ends of other pairs of intersecting members to form at those ends laterally disposed apexes of the diamonds so that when the rows are all contracted and the vertical apexes of the diamonds are drawn together, the diamonds are collapsed about their lateral apexes.
