Definitions

  • the invention relates to a tiltable door structure of thetype wherein a door is suspended on one or more hinged arms, so that when opening or closing the door the lower side thereof moves in the plane, in which the door opening is arranged or in a plane parallel thereto, and the lower side of the door being guided.
  • the invention is applicable ⁇ not only for doors vbut also for suspended windows or panels.
  • a hinged arm is at oneendconnectedjwith the wall, in which there, is arranged the opening to be closed by the said door or window.
  • Fig. 1 is a schematic view, partly in section that shows an almost completely opened door with the wall, to which the door is iixed, with triangle of forces belonging to it.
  • Fig. 2 is a schematic view, partly in section, similar to Fig. l, but shows a corresponding schematic performance with the door in an almost closed position, also with a triangle of forces belonging to it.
  • Fig. 3 and Fig. 4 are schematic views that show the ratio between the lengths of the hinged arm and the distance of the guide of the lower side of the door up to the fastening point of the hinged arm.
  • Fig. 5 is a schematic elevational view that shows a way of attachment of the spring to the door and the fixed wall.
  • the door I has at the lower side guiding rollers 2, which when opening and closing the door roll along the guides 3 in the plane of the wall 4.
  • the door l is fixed by means of the hinged arm 5.
  • Said hinged arm is xed to the wall at 6 and to the door at l.
  • the length of the hinged arm between the two pivoting points is indicated at C, whereas the distance between the roller shaft and the pivoting point 'l is indicated at D.
  • C is larger than D.
  • the vertical projection of I,the ⁇ compressive force becomes larger as the doorapproachesthe closed position (seeFg. 2 triangle of' forces) 1
  • the vertical-component of the compressive force If the door is brought from ⁇ the closedinto the open position, inthe beginning, the largest force must. be exerted upwardsin vertical direction on the lower s ide 'of the door.
  • a tension spring is fixed at one end to Vthe lower side o f the door (such as one of the springs schematically indicated at 8 and l I of Fig. 5), and the other spring end is attached to a xed point in such a way that for closing the door the spring is stretched, the spring will be stretched more when the door is closed as the distance between the points 6 and 2 becomes larger. Therefore when the door is opened, that spring has in the beginning the largest influence, which decreases when the vertical component of the compressive force becomes smaller.
  • a so-called pre-stretched tension spring is especially suited for acting in very different positions of the door.
  • the tension of the spring is largest in the completely closed position of the door and is decreased when the door is opened.
  • the springs can lie in the same or nearly the same plane as the door opening.
  • tension springs 8 and Il are attached at the lower side of the ⁇ door at both sides of the door, whereas the other ends of said springs are attached to the wall of the door opening at points 9 and I0 diagonally. opposite to the fastening points 2 oi' the springs to the door.
  • an overhead door structure including an apertured frame having a straight guide, a door movable relative to said frame between an aperture closing position and an opening position at right angle to the former and having an end sin 4 edge engaging said guide describing a substantially linear path.
  • pvot means mounted directly on said door within the connes thereof spaced from said end edge for a predetermined distance, and unitary rigid link means pivoted to said pivot means and to said frame, said link means having a length greater'than said predetermined distance, said predetermined distance being the sum of the length of said link means and the distance between said edge in closed position and the pivot point of said frame.
