Definitions

  • the exemplary and non-limiting embodiments of this invention relate generally to an insulated window pane spacer.
  • Windows, doors or buildings may have insulated windows where two or more panes are separated by a spacer.
  • the spacer has a structural function supporting the panes and the spacer also seals the space between the panes.
  • US5439716 shows an insulated window spacer.
  • FIG 6 shows an interior wall 60 which is joined to the U shaped spacer body by welding.
  • the spacer has a thickness of 0,13 mm (0,005 inches).
  • US5630306 shows bridge members made of a synthetic resin or composite material. In each case, it is preferred that the outermost dimension of the insulating spacer, provided by the synthetic resin or composite material bridge member, and no metal, contacts the inner and outer panes of the window unit.
  • DE10226269 also shows a spacer with bridges (called legs) made of plastic material.
  • the bridges are connected to metal side members by use of forks.
  • Insulated glass units employing new technology and materials may have a higher risk of leaking and failing. Accordingly well proven materials and solutions may be more desirable if the draw backs regarding heat loss can be reduced.
  • the disclosed aspects further provide a number of advantages, for example the material used to produce the spacer is reduced.
  • an advantage is that the production roll forming process is eliminated or at least simplified because the profile shaping is less complex.
  • an advantage is that the bridges enable easy modification of the spacer width.
  • the spacer joined from separate parts enables flexible production and less storing etc. because the spacer shape and spacer properties can easy be changed by replacing the spacer parts instead of having to set up a new forming tool.
  • the bridge and sidewall may be from different materials providing properties favourable to the bridge and sidewall respectively.
  • the spacer may be gas tight to enhance the sealing properties.
  • insulated windows typically include panes which are spaced apart by spacers installed between the panes at the pane edge portions.
  • the spacer must fulfil several requirements including: strength to hold panes during production, transport, installation. Withstand years of aging and thermal expansion/contraction. Minimize the thermal conduction e.g. heat loss through the spacer.
  • window constructions benefit from better insulation.
  • Window insulation performance is a result of tradeoffs in the construction. For example insulation may be improved by using different filling gas, pane coatings, layers of panes and pane material etc. And in some cases it may be advantageous to use a particular spacer for reduced heat loss.
  • Slim bridge members may have sufficient strength if they for example employ high strength metal or employ a rolling and/or corrugating process which hardens the bridges. Further when the spacer is welded from separate members the welding may further increase the strength by hardening.
  • Fig. 1 shows a cross section example of a spacer profile comprising a first sidewall 1 and a second sidewall 2.
  • the sidewalls are connected and spaced apart by a first bridge 3 and a second bridge 4.
  • the sidewalls comprise an engagement portion 1 a configured to be adhered to confronting surfaces of panes and optionally a tapering portion 1b configured to hold sealing/adhesive material.
  • first bridge 3 is associated with the sidewall 1,2 upper part and second bridge 4 is associated with the sidewall 1,2 lower part.
  • the spacer has a substantially tubular cross section. This provides good strength and efficient production.
  • the tubular cross section may also contain desiccant, foam or reinforcement insert or combinations thereof.
  • the spacer is substantially rectangular.
  • the first bridge 3 is associated with the spacer top (facing the interior of the glass unit when installed).
  • the second bridge 4 is associated with the spacer bottom (facing the exterior of the glass unit when installed).
  • the first and second sidewalls 1,2 are associated with the respective sides of the spacer facing the panes when installed.
  • the first and second sidewalls 1,2 substantially extend between the first bridge 3 and the second bridge 4.
  • the rectangular spacer parts may be joined near the 4 respective corners.
  • the first sidewall 1 and the second sidewall 2 and the first bridge 3 and the second bridge 4 each are separate members joined together to form an assembly.
  • the first sidewall 1 and the second sidewall 2 and the first bridge 3 and the second bridge 4 are joined together by assembly means.
  • the first bridge and second bridge extend transversely between the first and second sidewall.
  • the first and second bridge 3,4 extend in substantially a co-planar relationship. In one example both the first bridge 3 and the second bridge 4 have similar cross section.
  • the present disclosure employs slim bridges 3,4 with low thermal conductivity.
  • the bridge members may be worked such as rolled and/or corrugated to provide slim and yet strong bridge members. Further when the spacer is welded from separate members the welding may further increase the strength.
  • the spacer bridge 3,4 is from metal and 0,1 mm thick or less.
  • the spacer bridge 3,4 is from metal and has thickness between 0,08 mm or less, preferably 0,05 mm or less.
  • at least the two bridges 3,4 are from metal and have thickness between 0,08 mm or less, preferably 0,05 mm or less.
  • the first bridge 3 and/or the second bridge 4 are substantially thinner than the first sidewall 1 and/or the second sidewall 2.
  • the thickness of one bridge e.g. sheet/profile thickness generally is lower than the thickness of one sidewall sheet/profile.
  • first bridge is thinner than the sidewall or the second bridge is thinner than the sidewall or both bridges are thinner than the sidewall.
  • the spacer e.g. sidewalls 1,2 and bridge 3,4 consists of separate joined metal parts only.
  • At least one bridge 3,4 is undulated along the longitudinal direction to provide enhanced strength and stability.
  • both the first bridge 3 and the second bridge 4 are undulated in the longitudinal direction in which the spacer profile extends.
  • the spacer strength is enhanced and the undulated shape may help to absorb thermal expansion in the longitudinal direction if the bridge 3,4 has thermal expansion different from the panes.
  • the bridge 3,4 is configured for increased transversal strength, by employing undulated shape.
  • the bridge 3,4 optionally is from different metal material than the sidewalls 1,2 e.g. the first and second bridges 3,4 are from a first metal material and the sidewalls 1,2 are from a second metal material.
  • first and second metal material is understood a material with different properties like heat conduction, heat expansion, strength, rigidity, seal material adhesion, forming ability etc.
  • the sidewalls 1,2 are based on ductile metal material and the bridges 3,4 are based on high strength metal material.
  • the sidewalls 1,2 are configured for forming and the bridges 3,4 are configured for less heat transfer.
  • a first and second metal material may be a stronger material, so the bridge 3,4 is from a metal material comprising higher strength than the material of the sidewalls 1,2.
  • the assembly has the advantage that for example the bridge first metal material 3,4 has enhanced strength while the sidewall 1,2 second metal material has enhanced forming properties.
  • a first and second metal material may be a material configured to adhere seal material.
  • the assembly has the advantage that for example the sidewalls 1,2 are from a second metal material having a surface configured for enhanced adhering of seal material.

  • the bridge 3,4 members may also be shaped or made from material to compensate the thermal expansion effect of the insulated glass unit.
  • a first and second metal material may be a material configured to have enhanced transversal compressive strength.
  • the bridge 3,4 may be of a first metal material configured to have enhanced transversal compressive strength.
  • the bridge 3,4 members extend between the sidewalls 1,2 are configured to provide reduced heat transfer compared to the sidewall 1,2 members. E.g. heat transfer transversely through the members.
  • Fig. 2 shows an example of an installed spacer.
  • the sidewalls 1,2 comprise an upper engagement portion 1 a configured to be adhered to confronting surfaces of panes 5,6 and a lower tapering portion 1 b configured to be adhered with sealing material.
  • the first and second sidewall 1,2 comprise an engagement portion 1 a which is perpendicular to the transverse direction of the bridge 3,4 and a tapering portion 1 b which slopes from the engagement portion 1 a towards the centre of the spacer.
  • the first bridge 3 when in use faces the interior space of the insulated glass unit and the second bridge 4 when in use faces the exterior.
  • the engagement portion 1 a is towards the interior and the tapering portion 1 b is towards the exterior.
  • the spacer is installed between two spaced apart panes 5,6 and the engagement portion 1 a is adhered to the pane 6 with a strip 7 or sealant, foam etc. while the tapering portion 1 b is adhered to the pane with sealant 8.
  • the sealant 8 optionally covers the whole spacer facing the exterior as illustrated by 8b.
  • the engagement portion 1 a is adhered to the pane 6 by primary seal means like a strip 7 or adhesive, sealant, foam etc.
  • the engagement portion 1 a is substantially orthogonal to the bridge and faces the pane when in use. In one example the engagement portion 1a is substantially planar.
  • the engagement portion 1 a optionally is concave to provide a cavity towards the pane.
  • the engagement portion 1 a optionally has a shape adapted to minimize contact to the pane and thereby configured to reduce the heat transfer.
  • the tapering portion 1 b is configured for secondary attachment.
  • the tapering portion 1 b is optionally a cavity configured to contain seal material 8.

  • the stepped/waved tapering portion 1 b enhances the application and bonding of the seal material.
  • the stepped tapering portion 1 b is compatible with the fold 11 described.
  • the stepped tapering portion 1 b may employ a fold at the upper and lower end ( fig 5a ), employ a fold 11 at the lower end ( fig 5b ) or employ a fold 11 at the upper end ( fig 5c ).
  • Fig. 6a shows a bridge 3,4 with an undulating or corrugated shape in the transversal direction.
  • Fig. 6b shows a bridge 3,4 with an undulating or corrugated shape in the longitudinal direction.
