Definitions

  • the at least one transparent film is supported by the support structure.
  • the film can be secured directly to the edge spacer.
  • the film can be secured to the support structure wherein the support structure comprises at least one frame member located adjacent an edge of the film.
  • This at least one frame member can be a rigid frame made of rigid hollow aluminum profile with rectangle cross section (1 ⁇ 2” x 1 ⁇ 4”) and a wall thickness of 1/16”.
  • the rigid profile can be made of any material such as aluminum, stainless steel, reinforced thermoplastics, and other engineered composite materials with high rigidity. The thickness of the profile depends on the materials’ elastic modulus and its density.
  • the support structure can comprise a pair of frame members sandwiching an edge of the film.
  • FIG. 1 is a cross-sectional side view of a multi-pane insulated glass unit in accordance with the prior art.
  • Fig. 7A is a cross-sectional partial side view of frame/third pane in accordance with an embodiment of the invention.
  • Fig. 8B is a perspective view of the frame of Fig. 8A in accordance with an embodiment of the invention.
  • Figs. 12A-12D are cross-sectional partial views showing various arrangements for pressure equalization between the panels of the multi-pane insulated glass unit in accordance with the invention.
  • Fig. 13A shows a perspective view of a multi-pane insulated glass unit including a muntin in accordance with an embodiment of the invention.
  • the Fig. 4B arrangement shows a frame member 20 in a floating arrangement with the edge spacer 18.
  • the film 14 is secured to a plurality of frames 20 and the frames 20 are mounted interior to the edge spacer 18 such that it is outside of the edge spacer 18 and interior to the vision area 13 of the unit 10.
  • the frame members 20, can be secured therein with outer mechanical structures, such as welding or soldering, such that the frame is not structurally supported by the edge spacer 18.
  • the edge spacer 18 can be shaped such that when the panes 12 are attached to the edge spacers 18, the panes 12 are parallel to each other and to the film 14.
  • Primary sealant 16 can be positioned surrounding the edge member 18 and between the panes 12.
  • An adhesive can be arranged on either side of the film 14 between the frame members 20 and the film 14 to allow for securing the film 14 to the frame members.
  • the key/lock members can be a plurality of cone-shaped discrete members 52a, 52b running along the edges of the frame members 20a, 20b, which are configured to mechanically mate with the film 14 located therebetween.
  • Figs. 7A and 7B show a series of key/lock rod-shaped rounded members 54a, 54b extending along the length of the edges of the frame members 20a, 20b.
  • Figs. 8A and 8B show a series of key/lock rod-shaped continuous cone members 56a, 56b extending along the length of the edges of the frame members 20a, 20b.
  • the method further comprises trimming the film 14 after it is shrunk to the rigid state and secured to one of the support structure 20 and the at least one edge spacer 18.
  • the film 14 can be trimmed using a knife, blade, laser, and the like.
  • the film 14 can be secured to one of the support structure 20 and the at least one edge spacer 18 by at least one of a mechanical member, an adhesive, or a thermoplastic welding process.
  • the film 14 can also include at least one of materials embedded therein or coated on one or both sides to control transmission and/or reflection spectra.
  • a pattern can be printed on the film 14 either before or after the film 14 is affixed to the support structure 20 or the spacer 18.
  • Clause 5 The insulating glass unit of any one of clauses 2-4, wherein the film is annealed prior to or after securing the film to the support structure.
