Definitions

  • the invention relates to insulating glazing containing a spacer and the use of insulating glazing.
  • Insulating glazing is used extensively as glazing in buildings. Insulating glazing is also increasingly being installed in glass facades for aesthetic reasons, especially if the facade is optically designed as an all-glass facade.
  • Insulating glazing consists of at least two panes that are kept at a distance from each other by a spacer.
  • the panes may have a coating, such as a thermal and/or solar control coating.
  • Coatings containing silver in particular enable low transmission of infrared radiation and thus reduce the temperature inside the building.
  • the thermal insulation of insulating glazing is significantly better than that of single glazing and can be further improved with triple glazing.
  • Functional coatings or functional elements are generally required for this. Such functional coatings or functional elements usually have to be electrically contacted with a supply voltage, for which further components, such as connection elements and busbars, have to be provided. In principle, each additional component increases the complexity of insulating glazing and can worsen the insulating effect.
  • insulating glazing with an electrochromic coating requires electrical connections and busbars.
  • a problem associated with, for example, the busbars present in insulating glazing is that the busbars are visible from the outside which reduces the visible area of the window and is also unattractive from an aesthetic point of view.
  • the opaque coating or component can also affect the thermal properties of insulating glazing, as they usually have different thermal characteristics, e.g. thermal expansion, than the panes, which can lead to mechanical stress or even thermal breakage during temperature changes.
  • EP 2626496 A1 relates to a spacer comprising outer sidewalls, each sidewall having an inner projection.
  • the document also describes an insulating pane comprising at least two glazing panes spaced from the spacer profile, the inner projections of the spacer profile being in the formed space and serving to retain a space element located in the space.
  • EP 2628884 A2 describes a kit for insulating glass, comprising a plurality of spacer elements, each spacer element being made of plastic and comprising at least one metallic insert, the spacer elements in one embodiment having a projection on a side surface of the spacer element which protrudes into the interior of the insulating glass.
  • WO 2006/075922 A1 relates to an insulating glass comprising an inner roller shutter and a spacer, the spacer having a protruding part in the space between the insulating glass, which is shaped as a rail or wing and is provided with a sliding element.
  • DE 3432113 A1 relates to a pane assembly formed by spacers and panes with reflector profiles arranged in the air gap, which are used to control the passage of light through the pane assembly, the reactor profiles being able to be suspended in the spacers at the front and these spacers having extensions.
  • US6108999A describes a window glazing unit comprising a first pane of glass, a shatter resistant thermoplastic pane and a second pane of glass.
  • a spacer is shown separating the first and second glass panes and having a depression in the center in which the thermoplastic sheet is placed.
  • the spacer has projections on both sides of the depressions.
  • U.S. 2014/247475 A1 relates to an insulating glass unit comprising a first glass substrate, a second glass substrate, an electrochromic device positioned on the first or second glass substrate, two bus bars electrically connected to the electrochromic device, and a spacer.
  • the spacer may have cutouts or notches at the top and bottom inside corners of the spacer.
  • DE 10 2015 004913 A1 and SE 513 554 C2 also disclose insulating glazing comprising at least two panes and at least one spacer, in which the at least two panes form at least one glazing interior with the spacer.
  • the object of the present invention was therefore to overcome the problems in the prior art listed above.
  • the object of the invention was to improve the aesthetic appearance and to increase the transparent surface of an insulating glass pane in which there are elements to be concealed, such as busbars, as for example in the case of an insulating glass pane with electrochromic coating.
  • the task was also to produce such insulating glazing more cost-effectively and to improve its thermal stability.
  • This object can be achieved by attaching a privacy screen directly to the spacer of the insulating glazing to conceal the area where the component to be concealed, such as a bus bar, is located in the insulating glazing.
  • a significant improvement in the aesthetic appearance of the insulating glazing can be achieved by using the spacer in insulating glazing which has components to be covered, such as busbars.
  • the coverage area can be made smaller with the same effect because the privacy window is closer to the component to be covered.
  • This also increases the transparent surface of the insulating glazing.
  • the screening wall and the spacer can easily have the same color, which is necessarily the case in some embodiments, which makes the appearance more uniform.
  • Another advantage is that no additional production steps, such as the application of a screen print, are required for the cover, which reduces production costs and shortens processing times.
  • this leads to improved thermal properties of the insulating glazing, since the use of opaque coatings for covering, which have different thermal properties compared to the panes used, can be avoided. With normal insulating glazing, breakage can occur when the temperature changes if the area of the screen print to cover is too large. Larger coverage areas are possible thanks to the spacers.
  • the width of a base body relates to the direction from the first side contact area to the second side contact area.
  • the height of a body relates to the direction from the exterior surface to the interior glazing surface(s).
  • the longitudinal direction is correspondingly perpendicular to the width and height along the side contact area.
  • Cross-section refers to the cross-section across the two disc contact surfaces unless otherwise noted.
  • Insulating glazing comprises at least two panes that are kept at a distance from one another by a spacer.
  • Another name for insulating glazing is multi-pane insulating glass.
  • the spacer for insulating glazing comprises a base body and at least one screening wall.
  • Spacers that space two panes apart are common. These can be used in general for multi-pane insulating glass, such as double-pane insulating glass, triple-pane insulating glass and four-pane insulating glass. Accordingly, two or three such spacers are required for three-pane insulating glass and four-pane insulating glass, a first spacer for spacing one outer pane from the inner pane and a second spacer for spacing the other outer pane from the inner pane. Spacers are also used, which can space three panes apart.

  • the connecting surface may be at an angle in the range of 30° to 60° to the outer surface.
  • the two disk contact surfaces are generally approximately perpendicular or perpendicular to the plane in which the outer surface is located.
  • the glazing interior surface of the base body A can usually be connected directly to the first and second pane contact surfaces. This direct connection is generally preferred, but the glazing interior surface can also be connected to the first and/or the second pane contact surface via connection surfaces. In this way, each pane contact surface is connected directly or indirectly to the exterior surface on one side and directly or indirectly to the interior glazing surface on the opposite side.
  • the two pane contact surfaces are generally approximately perpendicular or perpendicular to the plane in which the interior glazing surface is located. It usually is preferred that the outer surface and glazing interior surface run parallel to each other.
  • the base body A can optionally have one or more cavities in the interior.
  • the glazing interior surface preferably has openings in order to facilitate the absorption of atmospheric moisture by desiccants that may be present in the base body.
  • the dimensions of the base body depend on the dimensions of the insulating glazing in which it is to be used.
  • the width of the base body A can be, for example, in the range of 4 to 30 mm, preferably 8 to 16 mm.
  • the height of the base body A can be, for example, in the range from 5 to 15 mm, preferably 5 to 10 mm.
  • the base body B which is suitable for the spacing of three panes, has a first pane contact surface and a second pane contact surface running parallel to the first pane contact surface, a first glazing interior surface, a second glazing interior surface, a first inner side surface, a second inner side surface and an outer surface.
  • the two inner side surfaces run between the two pane contact surfaces and parallel thereto and together with the two glazing interior surfaces and the outer surface form a groove for receiving a pane.
  • the groove is suitable for accommodating an inner or third pane.
  • two individual spacers can also be used for three-pane insulating glass to separate two panes.
  • the outer surface of the base body B can be connected directly to the first and second disc contact surfaces.
  • the outer surface is connected to the first and/or the second disk contact surface via connecting surfaces, i.e. via a first connecting surface to the first disk contact surface and/or via a second connecting surface to the second disk contact surface, with both disk contact surfaces preferably having such connecting surfaces with the outer surface are connected.
  • the connecting surface may be at an angle in the range of 30° to 60° to the outer surface.
  • the two disk contact surfaces are generally approximately perpendicular or perpendicular to the plane in which the outer surface is located.
  • the first glazing interior surface of the base body B can usually be connected directly to the first pane contact surface and the first inner side surface.
  • the direct connection is generally preferred, but the first interior glazing surface can also be connected to the first pane contact surface and/or the first inner side surface via connection surfaces.

  • the two interior glazing surfaces preferably have openings in order to facilitate the absorption of atmospheric moisture by desiccants that may be present in the base body.
  • the dimensions of the base body depend on the dimensions of the insulating glazing in which it is to be installed.
  • the width of the base body B can be, for example, in the range from 10 to 50 mm, preferably 20 to 36 mm.

  • the privacy wall is made of opaque material, so that an object located behind the wall cannot be seen.
  • the height of the privacy screen can vary as required and depends, among other things, on the position and dimensions of the element to be concealed in the insulating glazing, the position of the privacy screen relative to the element to be concealed and the desired degree of privacy with regard to the viewing angles to be considered.
  • the height h of the privacy screen refers to the distance between the interior glazing surface on which the privacy screen is located and the top of the privacy screen. In general, it has proven to be useful if the height h of the screening wall is the same as or higher than the height of the element to be covered, eg a bus bar.
  • the height of the element to be covered is understood to be the distance between the plane of the interior glazing surface on which the screening wall is located and the upper end of the element to be covered.

  • the privacy wall can have any geometry in cross section, which can be selected according to the expediency.
  • the screening wall can, for example, have a rectangular basic shape in cross section, or the screening wall can taper in cross section at least partially from bottom to top, for example trapezoidal or triangular.
  • the basic rectangular shape includes, for example, a rectangular shape or a rectangular shape with rounded edges at the top of the privacy screen.
  • a screening wall which at least partially tapers from bottom to top in cross-section, preferably conically tapering, can be advantageous for manufacturing and/or stability reasons.
