Definitions

  • the invention relates to multi-pane insulating glass and glazing according to the preambles of claims 1, 7, 10 and 12.
  • Such multi-pane insulating glass is mainly used for windows of buildings and vehicles. It is subject to constant fluctuations in temperature and atmospheric pressure. In the event of temperature fluctuations, the adhesive points are subjected to changing compressive and tensile stresses due to the different thermal expansion of glass and metal, the changes in atmospheric pressure and changes in atmospheric pressure in the space between the glass panes as a result of temperature fluctuations. This applies accordingly to the surfaces of the sealing compound adhering to the glass panes.
  • Atmospheric air which is always more or less moist, mainly enters the space between the glass panes when the atmospheric pressure exceeds the pressure in the space or the air pressure in the space drops. Not only the atmospheric pressure, but also the pressure in the closed space between the glass panes is subject to constant fluctuations, because it increases and increases with increasing temperature falling temperature, even if the atmospheric pressure remains constant.
  • the invention seeks to remedy this.
  • the invention as characterized in claims 1, 7, 10 and 12, solves the new problem of creating a multi-pane insulating glass or glazing in which condensation on the inside of the glass panes is avoided for a practically unlimited duration can.
  • Particular embodiments of the invention are specified in the dependent claims.
  • the advantages achieved by the invention are essentially to be seen in the fact that the multi-pane insulating glass has a practically unlimited duration in the state in which there is no condensation on the inside of the glass panes can be held.
  • the desiccant or the desiccant container can be simply replaced with the desiccant as required or as a precaution at certain intervals.
  • the ingress of atmospheric air with an inevitably not absolutely impervious edge connection is avoided by automatically adjusting the pressure in the space between the glass panes to the respective atmospheric pressure.
  • crowning which leads relatively quickly to leaks, has so far occurred in particular in the case of coated glass panes in summer, in which the air in the interspace is heated to a great extent, the crowning also being unsightly with such reflecting panes (interference / mirror images).
  • Multi-pane insulating glass according to the invention with a much narrower space between the glass plates, that is to say, overall thinner than before, even with the same glass pane thickness.
  • the adhesive layer applied in an edge region of the glass panes can suffice as a spacer.
  • a multi-pane insulating glass 1 in its basic structure consists of two glass panes 2 and 3, which are firmly and tightly connected to each other at a small distance from one another in their edge region 4, and a desiccant container 5, which contains a desiccant 6 and is tightly connected to the space 7 between the glass panes 2 and 3.
  • the glass panes 2 and 3 are connected to one another by an adhesive layer 8 and a sealant layer 9, which run directly next to one another in the edge region 4 and form a connecting and sealing frame, the thickness of the layers being the distance and thus the space 7 between the glass panes 2 and 3 determined.
  • a frame can be arranged between the panes and glued to them, the sealant layer 8 enclosing the frame.
  • the desiccant container 5 is tubular and extends almost along the entire length of an edge side of the glass panes 2 and 3 which are connected to one another.
  • One leg 11 of the angle piece 10 is tightly guided through the connecting and sealing frame 8/9 shown in section in FIGS. 3 and 4 and firmly connected to the two glass panes 2 and 3.
  • the other leg 12 is connected to the desiccant container 5 by a tight detachable plug connection.
  • the desiccant container 5 is dismantled from the pipe leg 12, emptied, filled with new or regenerated desiccant 6 and reconnected to the pipe leg 12. Instead, the desiccant container 5 can also be replaced together with the desiccant 6, the replacement container having to remain airtight until it is used. If it is the glazing of a motor vehicle, it is advisable to do this together with other maintenance or revision work.
  • the air humidity or dew point of the air in the container 6 can also be measured at regular intervals with a hygrometer and the desiccant 6 or desiccant container 5 can be replaced on the basis of the measurement result.
  • the desiccant container 5 could also be non-detachably connected to the pipe leg 11 and be provided with an opening for emptying and filling or a lower emptying and an upper filling opening with releasable closure means.
  • the desiccant container 5 can be at least partially made of resilient material or resiliently shaped, for example in the upper area as a corrugated tube, or consist of a bag or bellows, preferably made of rubber, so that it is between the atmospheric pressure and the pressure in the space 7 between the glass panes 2 and 3 deformed and this pressure matches that. In order not to make this difficult, only a lower part of the desiccant container should be filled.
  • the desiccant container is expediently made of transparent material or it is provided with a window made of such material.
  • a larger desiccant container 15 is connected to a pipe socket 17 by a detachable connecting line 16.
  • the connecting line 16 expediently consists of flexible material, so that it can be connected tightly but releasably to the pipe socket 17 and the desiccant container 15 by means of pipe clamps 21. Otherwise, the above explanations for FIGS. 1 to 3 apply mutatis mutandis.
  • each of three assemblies 25, 26, 27 has two glass panes which are tightly and firmly connected to one another at the edge, in the space between which a pipe socket 17 leads, as explained in relation to FIG. 5.
  • a branch of a line 29 is connected to each of the pipe sockets 17 and is connected to a desiccant container 30 and a chamber 31 of a vessel 32.
  • the desiccant container 30 is dimensioned for receiving desiccant 6 for the spaces between the glass panes of all three assemblies 25, 26, 27.
  • the desiccant 6 can be replaced.
  • the other chamber 33 of the vessel 32 is open. Both chambers 31 and 33 are separated from each other by a resilient membrane 34 which, for. B.
  • the plastic membrane can be used for verbs Leak tightness coated metallic or with a metal foil, for. B. be provided with an aluminum foil. It prevents the penetration of (moist) outside air, thus ensures a long effectiveness of the desiccant and enables the internal pressure in the assemblies 25, 26, 27 between their glass panes to automatically adjust to the external atmospheric pressure.
  • the vessel 32 can also be omitted and the line has an open line end exposed to atmospheric pressure for the purpose of venting and venting the intermediate space in the event of fluctuations in the atmospheric pressure, the desiccant container being expediently connected to the line in a replaceable manner. Otherwise, the explanations for FIGS.
  • FIG. 6 Arrangements of the type described in connection with FIG. 6 are advantageous for the windows of buildings and vehicles (eg motor vehicles, railroad cars, aircraft) because for several windows desiccant only needs to be replaced at one point, this point can be selected so that it is easily accessible, expediently in a vehicle so that the desiccant is replaced at a point where other maintenance work is also carried out regularly is.
  • buildings and vehicles eg motor vehicles, railroad cars, aircraft
  • the desiccant container 30 can also be omitted if dry air is filled into the intermediate spaces and the line 29, the penetration of moisture being prevented by the pressure compensation of the expansion vessel 32. Accordingly, in the embodiment of FIGS. 1-3, the expansion vessel 32 can be provided instead of the desiccant container 5.
  • a desiccant is contained in the cavity of the frame (spacer frame) of the multi-pane insulating glass 20.
  • the connecting piece 17 opening into the space between the two glass panes and the frame is connected by a pipe 35 to the top of a condensate collection vessel 36, to the lower, funnel-shaped outlet of which a vertically downward-extending capillary tube 37 is connected, the lower, open end of which is atmospheric Is exposed to pressure so that the space between the glass panes is ventilated and vented when the atmospheric pressure fluctuates.
  • the capillary tube 37 is placed in a cool place for the condensation of moisture from the incoming air. When the atmospheric pressure rises, the condensate collection vessel 36 collects condensate which has been pushed upward and which is expelled again through the capillary tube when the atmospheric pressure falls.
  • a desiccant container 30 is inserted into the tube 35. 6, the desiccant container 30 can also be connected to the line 35, the connection preferably being detachable for the purpose of replacing the container.
  • the capillary tube 37 and the vessel 36 largely protect the desiccant container 30 from the moisture in the outside air, so that it only absorbs the moisture that does not condense in the capillary tube 37 (if it is too warm) and therefore remains effective for very long periods of time.
  • a vessel 32 corresponding to FIG. 6 is inserted into the tube 35.
  • the space between the glass panes communicates with the cavity 31 and the cavity 33 separated therefrom by the membrane 34 communicates with the atmosphere via the vessel 36 and the capillary tube.
  • the membrane 34 yields in the event of changes in the difference between the internal pressure in the intermediate space and the atmospheric external pressure, so that the internal pressure is adjusted to the external pressure.
  • the capillary tube 37 and the vessel 36 protect the membrane 34 from moisture, so that no particularly high requirements are imposed on the tightness (moisture impermeability) of the membrane 34 and a particularly well-flexible, thin plastic membrane can be used for an optimal pressure compensation without there is a risk that the membrane becomes moist and moisture diffuses through the membrane over time.
  • a long pipe or hose line with an open line end exposed to atmospheric pressure is connected to the connection piece 17 for the purpose of ventilation of the space between the glass panes in the event of fluctuations in the atmospheric pressure.
  • the line is dimensioned such that the volume of the air plug in it is at least as large as the maximum expansion of the air volume located between the lowest and the highest atmospheric pressure between the two glass panes. And the inside diameter of the line is so small that the air plug only moves as a whole in the event of pressure fluctuations, so that no damp outside air can get directly into the space between the glass panes due to a turbulent air flow.
  • the multi-pane insulating glass can also have more than two glass panes which are tightly connected to one another at their edges (directly or via a frame in each case), the two or more spaces between the glass panes having one or each desiccant container 5, 30 and / or an expansion vessel 32 or above a pipe is connected to the atmosphere.
  • the multi-pane insulating glass or the glazing can, as mentioned, be used for vehicles, buildings, railroad cars, airplanes, also for ships and for machine and apparatus construction, for. B. for showcases.
  • the multi-pane insulating glass according to the invention can also be designed with one or preferably two closable connecting pieces which lead into the space between the glass panes instead of with a desiccant container or an expansion vessel. If the dry air filled into the intermediate space has become moist, it can then be replaced by dry air in each case: in the embodiment with only one nozzle, by alternately sucking and blowing dry air through the nozzle; in the embodiment with two nozzles by blowing dry air into one nozzle and discharging or sucking out the moist air through the other nozzle.
