Definitions

  • a folding panel or door for covering windows, doors or the like made up of a plurality of hingedly connected vertical slats.
  • the hinges are formed integrally on the slats, one of the hinge elements being semi-cylindrical and the other hinge element having a retaining flange for receiving or being received by the semi-cylindrical member.
  • Spring members are provided within the retaining flange to urge the hinge elements together in every position the slats might take relative to one another.
  • One type of such a panel comprises a plurality of elongated, vertically arranged slats which are hingedly mounted together.
  • the hinges used in such a panel generally comprise first and second hinge elements integrally formed with the slats and a third hinge element such as a hinge pin.
  • the slats are provided with carriers which slide in tracks mounted along the upper surface of the opening or along both the upper and lower surfaces.
  • Such a panel can be extended and retracted either manually by pulling or pushing the leading slat or by use of conventional traversing mechanisms such as those employing a cord and pulley system.
  • the use of the third hinge element increases the cost of the panel because it cannot be integrally formed with the slats. It also increases the cost of the assembly of the panel as the hinge elements integral with the slats must first be positioned and the third hinge element then slid into place.
  • Several proposals have been advanced for providing a two-element hinge; however, the construction of these hinges prevents their opening and closing all the way, that is, from a fully retracted or stacked position to a fully extended position.
  • a foldable panel or door in which the various slats are provided with hinge elements which cooperate in such a manner to permit the panel to be completely retracted or extended and yet do not require the use of a third hinge element.
  • spring members are positioned within the hinge to urge the elements against each other in every position that the panel assumes. This greatly reduces undesired sounds but does not interfere with the opening and closing of the panel. The spring members also prevent the panel from drifting from the open position as the result of wind or other influences.
  • FIGURE 1 is a front elevation of a folding panel or door according to the present invention
  • FIGURE 2 is a cross-sectional view taken along lines 22 of FIGURE 1 and showing the panel in the extended or closed position;
  • FIGURE 3 is a cross-sectional view taken along lines 33 of FIGURE 2;
  • FIGURE 4 is a cross-sectional view showing a portion of the panel in the retracted or opened position
  • FIGURE 5 is a cross-sectional view taken along lines 5-5 of FIGURE 4;
  • FIGURE 6 is a cross-sectional view of a modification of the panel shown in FIGURES 15;
  • FIGURE 7 is a partial perspective view showing the spring member used in the modification of FIGURE 6.
  • a folding panel or door 10 is constructed of a plurality of elongated, vertically arranged slats 11.
  • Each of the slats 11 is provided at one side with a curled edge which forms a semi-cylindrical portion 12 having an internal cavity 13.
  • the other side of each of the slats 11 is provided with a retaining flange 14 having a depending lip 15.
  • the extreme edge of this side of each slat 11 is also provided with an upstanding limiting lip 16 which functions to prevent the panels extending into a flat position.
  • an elongated serpentine leaf spring 17 Positioned in each of the retaining flanges 14 is an elongated serpentine leaf spring 17.
  • the retaining flange 14 serves as the female member with the semicylindrical portion 12 of the adjacent slat serving as the male member.
  • the lip 15 retains the semi-cylindrical portion 12 within the flange 14.
  • the spring 17 urges the portion 12 against the flange 14 and thus prevents these two members from relative lateral movement. The spring 17 is maintained in place by the lip 16.
  • the hinge elements When the panel or door is near its retracted or compacted position, the hinge elements reverse their func tions as is shown in FIGURE 4. As can be seen from FIGURE 4, the portion 12 now acts as the female member, retaining in its cavity 13 the lip 15 of the flange 14. Once again, the spring 17 serves to urge the two hinge elements together to prevent their relative lateral movement. As can be seen, this reversing of the function of the two hinge elements permits the adjacent slats 11 to be folded into parallel relationship.
  • each of the slats 11 may be provided with a carrier 18 for sliding in a track 19 mounted adjacent the upper surface of the opening to be covered. If desired, the movement of the carriers can be controlled by a conventional pulley and cord transversing mechanism as indicated by the cord 20.
  • FIGURES 6 and 7 show an embodiment of the folding panel or door of the present invention in which the elongated serpentine spring is replaced by a plurality of individual spring members 21, preferably of spring steel and bent so as to force the hinge elements together.
  • the spring members 21 are preferably bent at one end to form teeth 22 which dig into the surface of the slat facing the retaining flange 14.
  • other spring configurations could also be used to perform the functions performed by the spring members 17 and 21.
  • a foldable panel or door comprising a plurality of elongated slat members; hinge means cooperatively coupling adjacent slat members whereby said panel can be extended or compacted, each of said hinge means comprising a semi-cylindrical member formed along the edge of one of said slat members and a retaining and limiting means formed along the edge of the nextadjacent slat member, said retaining and limiting means comprising a flange extending from said slat member and having a portion extending generally parallel thereto, a retaining lip depending from said portion toward said slat member, and a limiting lip formed on the edge of said slat and extending upwardly therefrom, the upper edge of said limiting lip being spaced from said slat member by a distance less than the distance between th lower edge of said depending retaining lip and said slat member whereby an opening is formed between said lips for receiving said semi-cylindrical member, said retaining lip retaining said semi-c
  • said spring means comprises an elongated serpentine leaf spring.
  • said spring means comprises a plurality of curved spring members spaced along said retaining and limiting means.
