Definitions

  • the exemplary and non-limiting embodiments of this invention relate generally to an insulated glass unit and more particularly to an intermediate sheet in the insulated glass unit.
  • IGU insulated glass units
  • Some IGU employ an intermediate sheet between the two outer panes.
  • GB1398434 shows an intermediate sheet held by a clip spacer. The objective is that the clip spacer is resilient an urges the two panes outwards towards the frame.
  • EP1101955B1 shows an intermediate sheet which is held by a stiffening profile 4.
  • the profile is in contact with the outer panes and able to slide on the outer panes.
  • the objective is impact resistance.
  • EP1529921 shows a vacuum glass unit with an intermediate sheet. Vacuum units employ very small gaps between the panes (0,1mm). The panes are spaced by spacer strips 32 which extend along the width of the window. The objective is to compensate the temperature expansion.
  • WO94/24398 shows an intermediate sheet positioned by spacing elements 21 fig. 1 and 62 fig. 10 .
  • the objective is to space apart the panes by using the intermediate sheet as a spacer and omit the structural edge spacer by using a hermetic edge seal D.
  • Any reference to a/the sheet is referring to the at least one intermediate sheet 3 between the panes 1,2.
  • insulated windows with 3 or more panes employ identical sealed spacers between the panes. This is simple but a cost and production intensive solution which results in heavier and thicker glass units.
  • the present disclosure employs a light weight non glass intermediate sheet which does not depend on sealed the spacers but rather employs protruding position means 4.
  • Vacuum insulated glass units may employ an intermediate sheet with pillars, but the objective is to provide high compressive strength by small high strength pillars which are provided regularly on the entire surface.
  • the present disclosure differs at least by employing protruding position means 4 located at the proximity of the intermediate sheet periphery. And the present insulated glass unit does not have vast compressive forces towards the protruding position means, so the intermediate sheet 3 may expand substantially free by thermal expansion.
  • the intermediate sheet may further provide a number of advantages because the sheet may efficiently be fitted during production and have a coating providing light and/or heat controlling properties.
  • the intermediate sheet 3 has freedom to expand at room temperature, because the intermediate sheet 3 height and width is substantially smaller than the enclosed height and width of the insulated glass unit.
  • Figure 1 shows a cross section example of insulated glass unit comprising a first pane 1 and a second pane 2 spaced apart by a spacer 5.
  • a spacer 5 is sealed to provide a sealed enclosure between the panes 1,2.
  • the seal may be a first seal 6a and a secondary seal 6b which may optionally extend across the whole spacer exterior 6c.
  • the spacer may have a hollow interior containing a supply of desiccant material configured to remove moisture from the enclosed space between the panes 1,2.
  • the pressure in the sealed enclosure in the insulated glass unit may be substantially atmospheric.
  • the spacer 5 has a body between the spacer interior surface 5a and spacer exterior surface 5b.
  • the insulated glass unit has an interior enclosure defined by the panes 1,2 and the spacer 5 body interior surface 5a.
  • Figure 2 shows a similar cross section example of insulated glass unit further comprising an intermediate sheet 3.
  • the intermediate sheet 3 is positioned in the enclosure by protruding position means 4.
  • the protruding position means 4 are adapted accommodate the intermediate sheet 3 between the panes 1,2.
  • the protruding position means 4 are not hidden by the spacer 5.
  • the protruding position means 4 are not engaged with the spacer 5.
  • the position means 4 may be substantially translucent to minimize the disruption of the view through the insulated glass unit.
  • the protruding position means 4 are configured to maintain a distance between the panes 1,2 and the intermediate sheet 3.
  • the protruding position means 4 are provided on both sides of the intermediate sheet 3.
  • the protruding position means may be pillars 4 or the protruding position means 4 may be longitudinal profiles 4 extending along the intermediate sheet 3 edge. Various examples of the protruding position means 4 are shown later.
  • the sheet 3 is low weight meaning that the sheet is non glass.
  • the sheet 3 is polymer such as PMMA, acryl, polycarbonate, PET etc.
  • the sheet 3 may be laminated with other non glass sheet or laminated with a thin glass sheet or contain particles etc.
  • non glass sheets such as polymer sheets are lighter than glass sheets and it is hereby possible to reduce the weight. Further polymer sheets tend to have greater thermal expansion than glass which needs to be accommodated.
  • the protruding position means 4 are prefreably adapted to appear substantially transparent and may be made from same material as the intermediate sheet 3.
  • first protruding position means extending substantially transversally from the plane of the intermediate sheet 3 in a first direction and a second protruding position means extending substantially transversally from the plane of the intermediate sheet 3 in a second opposite direction.
  • the phrase 'extending transversally' is broadly speaking, that the protruding position means 3 have a body that occupies a transverse space and not limited to perpendicular.
  • Figure 3 shows an example of a perspective view of the intermediate sheet 3.
  • the protruding position means 4 may be provided spaced apart by a certain distance.
  • the protruding position means are pillars 4 which may have any profiled shape and be solid or hollow like a pipe.
  • the protruding position means 4 may be secured to the sheet 3 for example by welding or adhesive. In particular welding may be favourable when the protruding position means 4 are from similar material like the sheet 3.
  • Figure 4 shows an example of a perspective view of the intermediate sheet 3.
  • the protruding position means 4 may be curved projections 4.
  • the projections may be provided spaced apart by a certain distance and undulated so for example first half of the projections extend transversally away from the sheet 3 in a first direction and the second half of the projections extend transversally away from the sheet 3 in a second opposite direction.
  • the protruding position means 4 are integral and embedded with the intermediate sheet 3.
  • Figure 5 and 6 show examples of different popular structual spacers that hold panes 1,2 apart.
  • Fig. 5 shows a U shaped spacer and fig. 6 shows a hollow tubular spacer.
  • the spacer may also be a warm edge spacer made from foam or plastics. Combinations of plastic spacers enclosed by metal or vice versa may also be employed.
  • the spacer and associated sealant (not shown on fig. 5,6 ) seals the interior enclosure of the insulated glass unit.
  • the protruding position means 4 may be provided associated with the edge of the intermediate sheet 3.
  • figure 7 shows the protruding position means which may be legs 7 located at the edge of the sheet 3 and extend substantially transversally from the sheet plane in both directions.
  • the legs 7 may be integral with the sheet 3 and formed by deformation or drawing.
  • the legs 7 may be separate profiles (not shown) affixed on both sides of the intermediate sheet 3.
  • Generally elongated legs 7 or profiles enhance the stiffness of the intermediate sheet 3 and enable smaller sheet thickness and thereby lower the weight. This is particularly advantageous for roof windows that benefit from a stiff intermediate sheet 3 due to the inclined installation angle and gravity pull.
  • Figure 8 shows an example of the protruding position means 8 which may be a curved projection 8 which has a small obstruction of the daylight through the insulated glass unit.
  • curved projection 8 may be undulated so for example the first half of the projections extend substantially transversally away from the sheet 3 plane in a first direction and the second half of the projections extend substantially transversally away from the sheet 3 plane in a second opposite direction.
  • the curved projections 8 may be spherical or bubble like.
  • Figure 9 shows an example of the protruding position means 9 which is a terminal curl where a first part 9 extends in a first direction substantially transversally to the sheet plane and the second part 10 extends towards a second opposite direction.
  • the protruding position means may be elastic or have an elastic portion such as a bending protion whereby the position means 4 may adapt in the transverse direction.
  • the intermediate sheet 3 can be firmly held between the panes 1,2 without damaging the pane coatings.
  • Figure 10 shows an example of the protruding position means 9 which are provided by bent legs 11, 12.
  • the protruding position means 9 i.e. legs 11,12 are bent and extend in opposite transversal directions compared to the plane of the intermediate sheet.
  • the protruding position means 9 i.e. legs 11,12 extend alternating in a first direction and in a second opposite direction.
  • the protruding position means 4,7,8,9,10 are provided on the intermediate sheet 3 and position the intermediate sheet 3 inside the enclosed insulated glass unit by extending transversally from the plane of the intermediate sheet 3 and spacing the intermediate sheet from the panes 1,2.
  • the intermediate sheet 3 is positioned between the panes 1,2 autonomously from the spacer, meaning the sheet 3 does not rely on the spacer 5 to keep the distance to the panes 1,2.
  • Figure 11 shows another example of the intermediate sheet 3 and the protruding position means 11,12 which in this example are a substantially continuous elongated position means 11,12 along the periphery of the sheet 3 i.e. along the four edges.
  • the protruding position means 11,12 extend in opposite directions and thereby position the intermediate sheet 3 in between the panes1,2.
  • Two opposing edges have first protruding position means 11 extending substantially transversally from the plane of the intermediate sheet 3 in a first direction and the other two opposing edges have second protruding position means 12 extending substantially transversally from the plane of the intermediate sheet 3 in a second opposite direction.
  • the protruding position means 11,12 may be symmetrical and the opposing edges of the intermediate sheet 3 may extend transversally in the same direction.
  • the protruding position means 11,12 may be a substantially continuous bend along the periphery of the four edges.
  • the configuration in this example is simple to produce while providing high rigidity to the intermediate sheet 3. This is advantageous because the intermediate sheet 3 thickness
  • the intermediate sheet 3 is substantially non structual i,e. does not hold the panes 1,2 apart and it is substantially autonomous from the spacer 5. Hereby the intermediate sheet 3 may easily be inserted during production of the IGU.
