Definitions

  • the present invention relates to a multiple, in particular double, glazed windowpane assembly with a blind arranged internally in said windowpane assembly, said windowpane assembly comprising two parallel window- panes arranged on either side of a spacer profile com ⁇ prising at least one recess, said windowpane assembly further comprising a guide means for guiding the blind within the cavity formed between the two windowpanes of the windowpane assembly. Furthermore, the invention re ⁇ lates to such a guide means as well as the use thereof in a multiple glazed windowpane assembly.
  • WO-A-02/14642 suggests having a guide means in con ⁇ nection with the spacer profile that separates the two panes. It is indicated that this guide means could either be formed integrally with the spacer profile, or be a separate part attached thereto. Forming the guide means integrally with the spacer profile is, however, undesirable because it adds to the complexity thereof.
  • the spacer profile is tu ⁇ bular having a rather simple cross-section.
  • This allows the spacer to be bent to form the corners corresponding to the corners of the windowpane assembly.
  • this bending is performed in such a way that the corners do not block the passage through the tubular profile, thereby allowing the tubular spacer profile to be filled entirely with a particulate desiccant, by filling from one end only after the profile has been bent.
  • the guide means is to be an integral part thereof, the cross-section becomes more complicated, and bending of the corners whilst at the same time keeping the pas ⁇ sage through the profile open becomes increasingly com ⁇ plicated.
  • Such an integral arrangement is also disclosed in EP-A-1036912.
  • WO-A-02/14642 lists a number of commonly known ways of attaching one thing to another, but does not elaborate on them or even reflect on them. Thus some of the methods listed would be undesirable for the specific purpose, i.e. the rather harsh environment within the cavity, where temperature may vary substan ⁇ tially between a hot summer day and a cold winter night. Thus gluing would not be desirable because the glue would give off gasses to the hermetically sealed cavity of the windowpane assembly. Eventually, the gasses from the glue would form depositions in undesired places, such as on the windowpanes, thereby influencing the transparency thereof.
  • EP-A-483528 discloses a separate guide means, which is clamped between the two parts of a two-part spacer profile, where each of the two parts is a separate tubu ⁇ lar profile. Using a two-part spacer profile is not de- sirable, inter alia because of alignment problems and problems with increased heat conduction through the spacer profile.
  • DE-U-1906722 discloses a C-shaped guide rail for Venetian blinds.
  • the C-shaped guide rail could be placed between the windowpanes of a double glazed window.
  • double glazed windows it is fur ⁇ thermore known from inter alia DE-A-10011759 and WO-A- 01/88319, to use generally tubular spacer profiles with flanges serving as abutment surfaces for adhering and sealing the two windowpanes of a windowpane assembly.
  • this object is achieved by a multiple, in particular double, glazed windowpane assembly according to the opening para ⁇ graph, wherein the guide means is provided as a separate element, and where the guide means is adapted for me ⁇ chanical locking engagement with said at least one re ⁇ cess.
  • the above object is also achieved by a guide means for guiding a blind within a cavity formed between two windowpanes of an insulating windowpane assembly separated by a spacer profile having at least one recess, wherein the guide means is resilient so as to engage the spacer profile for accommodation in said recess.
  • the guide means allows the guide means to be located at least partially therein such that only the parts of the guide means which actually guide the blind protrude visibly into the cavity.
  • the effective light transmission area of the windowpane assembly is thus optimised.
  • at least one recess is formed between two flanges of said spacer pro ⁇ file, and the guide means engages said flanges for said locking engagement.
  • the profile of the spacer pro ⁇ file is kept simple, thereby allowing it to be bent with- out collapsing in the corners.
  • the two flanges are inclined with respect to each other so as to form an undercut recess, in which the guide means en ⁇ gage said flanges in a resilient manner for said locking engagement.
  • the guide means is resilient and engages said at least one recess to provide said locking engagement.
  • the spacer profile comprises more than one recess and the guide means engages said recesses.
  • the guide means according to the second aspect also to be used in multiple glazed windowpane assemblies, in which the recesses are not formed by flanges.
  • the guide means according to the invention comprises a metal pro- file shaped to form a compressible spring.
  • the guide means is made of aluminium, which is inter alia suitable for these operations.
  • the guide means comprises a U-shape and two flat portions, where each of the flat portions adjoins a respective leg of the U- shape.
  • the invention relates to the use of the guide means in a cavity formed between two windowpanes of an insulating windowpane assembly separated by a spacer profile.

  • fig. 1 is illustrated a double glazed insulating windowpane assembly 1.
  • the windowpane assembly 1 com ⁇ prises two windowpanes 2, 3, preferably made of glass.
  • the two windowpanes 2, 3 are held apart by a spacer pro ⁇ file 4 and a top box 5.
  • the spacer profiles 4 are generally tubular and made of alu- minium.
  • the top box is 5 also preferably of aluminium.
  • the two windowpanes 2, 3 are adhered to the spacer profile 4 and the top box 5 in a sealed manner, e.g. by means of butyl.
  • the two windowpanes 2, 3, the spacer profile 4 and the top box 5 thus form a sealed cavity 6.
  • an additional sealing material 7 is provided between the panes on the outside of the spacer profile 4 and the top box 5 with respect to the cavity. This material could be butyl, silicone, or any other appropriate sealing mate- rial.
  • the spacer profile 4 is generally tubular and filled with a desiccant, such as silica gel. This prevents the moist from penetrating fur ⁇ ther into the cavity 6, where it is undesired.
  • a desiccant such as silica gel.
  • a reflective coating is provided (not shown) .
  • the internal side is understood the side of the win- dowpane 1, 2 facing the cavity 6.
  • a coating is provided only on the internal side of the windowpane 2. However, a coating could be present on both of the win- dowpanes 2, 3. This coating serves to improve the thermal insulating properties of the windowpane assembly 1.
  • a blind 8 Integrated in the windowpane assembly 1, there is provided a blind 8.
  • a Ve ⁇ netian blind but the blind could be of any type commonly used, e.g. a roller blind, a pleated blind etc.

  • the guide means 9 is accom ⁇ modated in a recess in the spacer profile 4.
  • the spacer profile 4 and the guide means 9 used in the windowpane assembly 1 of fig. 1 according to the invention are shown in detail in both figs. 2 and 3.
  • Fig. 2 illustrates that the spacer profile 4 and guide means 9 are provided as separate parts. For illus ⁇ tration purposes, only relatively short segments of both the spacer profile 4 and the guide means 9 are shown.
  • the guide means 9 need not necessar ⁇ ily extend along the entire length of the spacer profile 4 along a side of the window.
  • the guide means 9 need not at all be present along the lower part of the spacer profile 4, i.e. the part extending horizon ⁇ tally in the normal mounting position of the window. Both the spacer profile 4 and the guide means 9 shown in fig.
  • the spacer profile is generally tubular with a trapeze-shaped cross-section of the internal passage 10.
  • the actual shape of the cross-section of the passage is not of im ⁇ portance for the invention as such, and could instead be e.g. rectangular.
  • the overall cross-section or profile of the spacer profile 4 it is of course ad- vantageous if it presents two planar parallel abutment surfaces 11 on which the windowpanes 2, 3 may be adhered.
  • the cross-section of the spacer profile 4 is preferably so that it can be bent to form corners 12, without blocking the passage 10. This allows the entire spacer profile 4 to be filled with the desic- cant in one go. Also, not having to cut the spacer pro- file 4 and join it at the corners 12, e.g. in mitre joints, greatly improves the sealing properties of the windowpane assembly 1.
  • the abutment surfaces 11 are at least partially consti- tuted by the outer surface of two flanges 13 along the length of the spacer profile 4.
  • outer surface is to indicate the surfaces of two flanges 13, respectively facing away form each other.
  • a recess 14 is formed between the flanges 13, i.e. between the inner surfaces, i.e. the surfaces, which face each other. At least partially, this recess 14 accommodates the guide means 9. That is to say, at least those parts acting as stop surfaces 15, may extend out of the recess.
  • spacer profiles with flanges are known as such, e.g. from the documents DE-A- 10011759 and WO-A-01/88319 mentioned above.
  • fig. 3 is shown how the guide means is accommo ⁇ dated in the recess 14.
  • the inner surfaces of the flanges 13 are inclined with re ⁇ spect to each other, so that the recess 14 is undercut.
  • This allows the use of a resilient guide means 9 to en ⁇ gage under the flanges 11 in mechanical locking engage ⁇ ment.
  • the resiliency providing the mechanical locking engagement may also be provided by the flanges, or by resiliency of both the guide means 9 and the flanges 13.
  • the guide means 9 secures itself in the recess 14 mechanically without the need for any other means, such as glue or the like.
  • the inclined surfaces are achieved by varying the thickness of the flange, the respective outer surfaces 11 may be parallel.
  • the guide means 9 is formed as a sin ⁇ gle piece of extruded aluminium.
  • the cross-section of the guide means is selected so that it does not only provide a stop surface 15, blocking the movement of the blind, but also spring properties. This is achieved by providing the stop surface 15 as one leg of a U-shape 16, forming part of the cross-section of the guide means 9.
  • the U- shape 16 allows an elastic compression of the guide means 9 in the direction across the length thereof, thereby al ⁇ lowing it to pass between the flanges 13 and resiliently engage in the undercut recess 14, and locks the guide means 9 mechanically therein.
  • the stop surface 15 acts as a stop surface in the sense that it blocks movement of the blind 8 in the direction of the windowpane 2, thereby preventing the blind 8 from damaging the reflective coat ⁇ ing thereon. It should be understood that a cross-section having similar properties could be achieved, not only by extru ⁇ sion but also by folding or roll forming an aluminium strip into the same shape. Also it should be noted that the resilient properties of the guide means 9 could be achieved by co-extrusion of different materials, viz.
  • the guide means 9 could be formed from materials having inherent elastic properties, e.g. suitable plastic material of a type not prone to give off gasses to the cavity. In this case a U-bend is not neces ⁇ sary but the guide means 9 could instead be generally T- shaped.
  • a flat part 17 of the guide means 9 adjoins one leg of the U-shape 16. This flat part 17 is adapted to lie flush with the bottom of the recess 14, so that the stop surface 15 of the guide means 9 is accommodated partly in the recess.
  • the part 18 of the guide means 9 adjoining the other leg of the U-shape is adapted to lie in parallel with the bottom of the recess 14, and ends in a bent 19 portion adapted to follow the inclined inner surface of the flange 13 providing a good aesthetic ap ⁇ pearance when the guide means is accommodated in the re ⁇ cess 14 of the spacer profile 4.
  • FIG. 4 is the same as in figs. 2 and 3.
  • the alternative embodiment of the guide means 9 of fig. 4 is adapted for the use with a windowpane assembly 1 in which both the windowpanes 2, 3 have internal coat ⁇ ings.
  • an additional U-shape 16a is provided in the flat part 17.
  • This additional U-shape 16 presents a stop surface 15a facing the stop surface 15.
  • This stop surface 15 prevents the blind 8 from contacting and damaging the reflective coating on the other windowpane 3.
  • the flat part 17 lies along the bottom of the recess. In this case between the stop surfaces 15, 15a, thereby allowing the blind 8 to engage them at a position within the recess 14.
  • the stop surface 15a need only, if at all, extend a lit ⁇ tle into the effective light transmitting area of the windowpane assembly 1.
  • An advantage of the making use of the features of the known spacer profile 4 in a multiple glazed window- pane assembly according to the invention is that while keeping the general windowpane construction the same, many different types of guide means 9, e.g. the different types described above, but also other types with possible modifications for special types of blinds 8, may be used.
  • Figs. 5a-m schematically illustrate various possi ⁇ ble cross-sections for the guide means 9, all of which provide the desired resilient properties for the guide means 9 and the ability to lock mechanically in the re- cess 14 between inner surfaces of the flanges 13.
  • Fig. 5a corresponds to the guide means 9 illus ⁇ trated in figs. 2 and 3.
  • Fig 5b corresponds to the guide means 9 illustrated in fig. 4.
  • Fig. 5c illustrate a third cross-section, which is symmetrical in the arrangement on either side of the flat part 17.
  • the U-shape 16a, the part 18a of the guide means 9 adjoining it, and the bent 19a portion adapted to fol ⁇ low the inclined inner surface of the flange 13 are thus identical.
  • This symmetrical guide means 9 provide a good aesthetic appearance when the guide means is accommodated in the recess 14 of the spacer profile 4, irrespective from which side it is later seen.
  • the guide means 9 according to fig. 5d in which the flat portion lies flush with both the other flat portions 18 and 18a.
  • Fig. 5e shows a cross-section resembling both of fig 5a and fig 5e, but where the flat portion is adapted to lie flush with the bottom of the recess 14 of the spacer profile 4, when the guide means 9 is mounted therein.
  • 5g to 5i show cross-sections, which generally correspond to those of figs. 5e, 5c and 5d, respectively, but with the difference that the stop surface is not pro ⁇ vided as a part of the U-shape 16, 16a. Instead simple uprights 21, 21a are provided, and essentially all of the necessary resiliency for the mechanical locking is pro- vided by the bent portions 19, 19a.
  • Such profiles are ad ⁇ vantageous, when they are manufactured by extrusion, be ⁇ cause they are less complicated. However they can also be manufactured by folding.
  • Figs. 5j and 5k illustrate profiles in which the bent portion 19, 19a is formed integrally with one leg of an asymmetric V-shape 22, 22a.
  • Figs. 51 and 5m show cross-sections of the guide means 9, in which essentially all of the resiliency is provided by the U-shapes 16, 16a. In this case, the free ends of the parts 17, 20, 20a engage under the flanges 13 of the undercut recess 14 of the spacer profile 4.
