Definitions

  • the invention relates to an insulating glass arrangement with an inner glazing and an outer glazing arranged at a distance therefrom and with a motor-driven sun protection or blackout curtain according to the preamble of claim 1 integrated in the preferably hermetically sealed space between the panes.
  • composite windows or composite doors or sliding doors are well known and in use.
  • a single pane of glass can be used as the inner glazing and a single pane of glass can also be used as the outer glazing.
  • Composite windows generally have good soundproofing and thermal insulation properties due to the larger air space between the panes.
  • sun protection or black-out blinds or roller blind mechanisms in the space between the panes of insulating glass is particularly attractive on the one hand because there are no external attachments on the window that would spoil the aesthetics of the window and the mechanism is completely encapsulated, meaning it is completely protected against dirt and mechanical damage.
  • the installation of sun protection or black-out blinds in the space between the panes of insulating glass poses particular problems due to the limited space available.
  • the entire mechanism must be very compact, but it must also be robust and fail-safe, because with conventional systems it is usually no longer accessible after installation, and it must still be fully functional.
  • sun protection or blackout curtains are to be used in this way for inclined windows, it is particularly important that the curtain, for example a film or a roller blind, i.e. during the closing process, is always taut and does not sag, because a sagging curtain in inclined insulating glass panes would rest on the glazing below and greatly increase the friction when rolling up and down, thus significantly impairing the function.
  • the DE 20 2005 007 921 U1 concerns a window pane suitable for both vertical and inclined windows and intended in particular for installation in the cavity between insulating glass panes.

  • the EN 10 2009 009 504 B3 relates to a multi-pane insulating glass for building windows, wherein three panes are bonded together to form a solid composite by means of spacers running around the edges, forming a gap between the panes, the middle pane is shorter than the two outer panes, so that an installation space is formed between the outer panes, in the installation space a winding shaft with a curtain is arranged, which can be adjusted into the gap between the middle pane and an outer pane.

  • a sensor surface arranged on a glazing 1, 2 of the insulating glass arrangement 10 for contactless operation and/or a capacitive sensor surface can be provided.
  • the power supply of the insulating glass arrangement 10 can be provided by means of rechargeable battery-operated batteries, ie rechargeable batteries, which can be charged contactlessly using an inductive charging system. This can be done when the window is closed or tilted, since the window frame, which contains a powered charging coil, and the battery-side charging coil, which is in the window sash or the Insulating glass arrangement is arranged close enough to each other or has contact.
  • rechargeable battery-operated batteries ie rechargeable batteries
  • the insulating glass assembly 10 has a Figure 12
  • the plug connection has the hermetically sealed plug 46 shown for the power supply of the insulating glass arrangement 10.
  • the plug connection must be moisture-tight. This is done by means of a rubber seal on the plug collar or plug. If, in this arrangement, cables are led out into the space between the panes, thus creating an inlet opening for moisture, for example, the plug connection still remains hermetically closed or sealed.
  • a further embodiment of the invention relates to a magnetic centering within the winding shaft 5, as the Figures 7 and 8th show.
  • a first permanent magnet 40 is arranged in an inner cavity 39 of a tube section 37 of the winding shaft 5 and an outer profile 38, in this case a square tube, has a second permanent magnet 41 which, in the assembled state, surrounds the first permanent magnet 40 in such a way that the magnetic poles of the permanent magnets 40, 41 face each other to form a magnetic centering, so that the distance between the tube section 37 of the winding shaft 5 and the outer profile 38 remains essentially constant due to the magnetic forces and the winding shaft 5 is held in position via the magnetic centering and bending of the winding shaft 5 is avoided.
  • the tubular section 37 of the winding shaft 5 and/or the outer profile 38 consist essentially of steel or of plastic containing magnetic components.
  • the polarization of the permanent magnets 40, 41 is designed such that the tube section 37 of the winding shaft 5 is arranged in a floating manner. This may be an attractive or repulsive interaction between the poles, since the magnetic forces act essentially radially around the inner tube.
  • the Figure 7 shows that a simple assembly of the winding shaft 5 with the curtain 3 is possible in that the winding shaft 5 is accommodated in a box-shaped housing 42, wherein the housing 42 with the winding shaft 5 arranged therein can be inserted into the insulating glass arrangement 10, in particular can be plugged onto a frame of the arrangement 10, and can be secured in the assembled position by means of a clip connection.
  • a modular structure is realized, which simplifies assembly and disassembly.
  • a drying agent which in particular comprises a silica gel and/or zeolite, can be provided in the space between the panes 4 between the inner and outer glazing 1, 2. This is known as a "warm edge" in windows.
  • the glazing 1, 2 can be accommodated in a frame of the insulating glass arrangement 10, which has further functional areas.
  • the glass panes 1, 2 are held securely and preferably hermetically sealed in the frame.
  • the frame has various functional areas, for example as a holder or guide for the traction elements 19, in particular the ball chain or toothed belt wheels or threaded spindles 32.
  • the drivers or the spindle nuts 33 coupled to the cross bar can also be accommodated in a guide on the frame.
  • the drying agent can be introduced in a further functional area of the frame.
  • a further functional area of the frame can have receiving means for receiving the box-shaped housing 42 with winding shaft 5.
  • the Figure 9 shows that the winding shaft or winding body 5 is arranged on its shaft via a torsion spring 51, wherein the winding shaft 5 is rotatable relative to the axis and connected to the axis via the torsion spring 51, which prestresses the winding shaft 5 relative to the axis in the winding direction.
  • the torsion spring 51 and the winding shaft 5 are firmly connected to the connecting pieces 52.
  • the connecting piece 53 is firmly connected to a ball wheel 54.
  • the torsion spring 51 is pre-tensioned by turning the connecting piece 53 counterclockwise or clockwise. The result of this is that the curtain 3 winds up onto the winding shaft 5. This continues until the cross bar 6 reaches its stop position (as shown) and the curtain 3 is wound up.
  • the curtain 3 moves downwards, the ball chain with the cross bar 5 and curtain 3 is moved downwards.
  • the torsion spring 51 is pre-tensioned once by turning the connecting piece 53 counterclockwise or clockwise so that the desired tension in the curtain is achieved.
  • the Figure 10 shows a design in which a spring compensation is achieved by a spring element 55 attached on both sides, which ensures an even tension of the curtain 3. This is particularly important for wide windows.
  • a shaped spring plate 55 is shown. Tension, compression or torsion springs can of course also be used.
