Definitions

  • the invention relates to an insulating glass pane with two individual panes and a spacer profile according to the preamble of claim 1.
  • Such an insulating glass pane with a spacer profile is known from DE-A-33 37 058.
  • the region of the side webs which has the sealing material is in each case formed by grooves which are directed into the interior of the hollow profile and are to be filled with the sealing material.
  • this known profile shape with grooves for receiving the sealing material requires a relatively large amount of sealing material because the entire groove cross section must be filled with it.
  • This relatively large amount of sealing material is not only expensive, but also ensures that a correspondingly high pressure arises in the sealing area, especially when the space between the panes bulges, as the narrow gap that is initially open to the outside in the case of non-deformed panes becomes narrower or even closed becomes.
  • a pumping action can thus occur, especially in the case of constantly changing deformations of the panes, and not always only on the outwardly directed sealing compound Opening gap is moved back and forth, but also gets into the contact area or the inside of the pane.
  • a spacer profile is known from DE-A-2 113 910, in which crowned side webs pass over horizontal web sections into an arched area which is external in the use position.
  • This transition area and an intermediate space formed by a protrusion of the two panes are filled with a putty-like mass, that is to say that a sealing material that remains permanently tough is not provided on the contact webs.
  • the tightness depends exclusively on the putty-like sealant.
  • a spacer profile which has spherical contact webs which delimit a wedge-shaped cavity opening towards the inside of the pane, so that sealant located there can be squeezed out into the space between the two panes when the pane moves.
  • the required amount of sealing material can be reduced without sacrificing tightness.
  • the cross-sectional width of the seal is kept narrow practically over the entire seal area, that is to say an advantageous narrow vapor diffusion width is maintained.
  • a relatively large cross-sectional length of the sealing area is achieved with a correspondingly good seal.
  • the disks can carry out the movements already mentioned, to which the sealing material can adapt in the best possible way, either by pushing it outward more by the narrowing of the wedge-shaped cavity or by sucking it back in, without higher pressures within the sealing material due to an increasingly narrow outlet gap arise that could lead to a transition into the interior of the space between the panes.
  • such a spacer profile can be designed cover with a consistently high spray pressure with sealing material, because the spray nozzle only has to be adapted to the slightly inclined side wall or has to be guided along it, which is easily and much easier than with a concave groove. Since no groove has to be filled, correspondingly little sealing material is required.
  • Another important advantage is that when pressing the surface covered with the sealing material with the disks only relatively low pressing pressures are required because the sealing material can deliberately escape into the widening wedge-shaped cavity, so that it has no tendency to towards the "wrong" side, namely to press towards the space between the panes.
  • Another advantage is that due to the inclined transition web, which adjoins the wedge-shaped narrow cavity, space is created for an edge-side sealing compound which can be effective in addition to the permanently tough elastic sealing material.
  • the very flat and narrow wedge-shaped cavity which widens only very slightly, desirably causes the correspondingly low need for sealing material, but it does nevertheless takes up a relatively large cross-sectional length overall and thus effectively prevents the ingress of moisture, especially since the diffusion width, as mentioned, is very small in a desired manner.
  • the sealing material protrudes beyond the wedge-shaped cavity towards the outside of the insulating glass pane and extends to the transition web or covers the inside beginning thereof.
  • the cross-sectional length of the sealing material can be increased further and an even better adaptation to disk movements can be achieved because an even larger supply of sealing material is then available for the reciprocating movement in the case of the disk deformations mentioned.
  • a particularly expedient and at the same time simple embodiment of the invention can consist in that the web area delimiting the wedge-shaped cavity is curved in cross-section in a straight line and / or extending, in particular convexly, away from the disk plane.
  • a first receding web area immediately adjacent to the contact area has an approximately rectilinear cross-section, to which a second, more receding area of the web can connect toward the outside, which encloses a larger angle with respect to the pane surface and / or has a curved cross section.
  • the first retreating Bridge area with a straight cross-section can be particularly easily covered with the permanently tough elastic material, for example butyl rubber, while the bridge area, which then retreats somewhat more, can accommodate a larger stock of sealant, so that any of the above-mentioned advantages of a good and constant adaptation can be maintained Disc movements can be compensated.
  • the transition from the contact area of the side web to the wedge-shaped cavity has a narrow or short, in particular approximately z-shaped gradation or Bend is to which the web area, which runs obliquely away from the disk to the transition web or to the cross web, adjoins the crossbar or the outer edge of the disk.
  • the sealing material cannot overcome such a small and hardly noticeable but significant gradation, because at the same time the corresponding contact pressure of the disks on the spacer profile occurs at this gradation, so that the sealing material does not pass over the wedge-shaped cavity in the contact area or even in the space between the panes appears excluded.
  • An embodiment of the invention of very considerable importance can consist in the fact that the web area facing the inside of the pane, serving as a spacer and system, in turn shrinks over at least part of its cross-sectional length with respect to the surface of the pane or via a convex curvature.
  • the pane in the area of its spacer can be increased by the amount present on the side web Swing the curvature or change of direction and swing, so that the contact point may even move inwards or outwards, depending on the deformation of the pane. The less the sealing material tends to migrate towards the inside of the pane.
  • this embodiment has the considerable advantage that the contact between the spacer profile and the disc is practically only a line contact running in the longitudinal direction of the profile, that is to say a point contact in cross section, so that the heat or cold transfer via the profile to a minimum is reduced.
  • the measure according to claim 9 has the advantage that especially in the immediate contact area of the two discs mutual support by the crossbar is improved because the contact areas or the wedge-shaped cavity can be arranged on both sides of this inner crossbar.
  • Claim 10 specifies a possibility of how the contact web can be connected to the inner web via bends, which results in the design options of claims 11 to 14 which, despite the transverse web located in the contact area, permit a limited elastic flexibility in the contact areas.
  • a spacer profile denoted by 1 in all — also different — exemplary embodiments serves to fix the individual panes 2 of an insulating glass pane in the edge region at the desired spacing from one another.
  • This spacer profile 1 is a hollow profile, which can preferably be filled with desiccant. In all of the exemplary embodiments it can be seen that this hollow profile is essentially delimited by two spaced-apart transverse webs 3 - outside - and 4 - inside - which run transversely to the plane of the pane and by approximately parallel to the plane of the page, generally designated 5. According to FIGS.
  • the side webs 5 serve only in some areas as an abutment for the individual disks 2 and are also provided with a sealing material 6 that remains permanently tough, the area 7 of the side webs 5 that has the sealing material 6 compared to the contact area 8 lying directly against the disks 2 the side webs 5 has a level difference to be described in the following, particularly clearly in FIGS. 2 and 3.
  • sealing material 6 protrudes toward the outside of the insulating glass pane beyond the wedge-shaped cavity 9 and extends to the transition web 10 and even covers its inside beginning, so that a very large cross-sectional length of the side region of the hollow profile 1 is covered with sealing material 6 , that is, vapor diffusion is opposed by a correspondingly long, but at the same time advantageously only very narrow sealing cross section.
  • the contact areas 8 are free of sealing material, so that even with the extreme pane movements according to FIGS. 4 and 5, a transition of sealing material into the space between the panes is excluded.
  • the web area 7 delimiting the wedge-shaped cavity 9 can have different cross-sectional shapes, preferably straight in cross-section and / or curved, for example, extending away from the disk plane.
  • a first web region 7a which is immediately adjacent to the contact region 8 has an approximately rectilinear cross section, on the outside of which the Transition web 10 adjoins a second, more receding region 7b of the web 5, one opposite the pane surface Includes larger angle than the web area 7a and could possibly even have a curved cross section.
  • the wedge-shaped cavity is therefore provided with two sections and, after its exit, has a suddenly increasing expansion.
  • transition from the contact area 8 of the side web 5 to the wedge-shaped cavity 9 can be a narrow or short, approximately z-shaped gradation 11 or offset, to which the Transverse web 3 or to the outer edge of the pane 2 adjoining the web region 7 which extends obliquely from the pane 2 to the transition web or the transverse web.
  • this gradation 11 can of course be provided for both mutually opposite side webs 5, that is to say one of the two in FIGS.
  • Fig. 2 it is indicated that the web area 8 pointing towards the inside of the pane, serving as a spacer and support, can in turn slant over at least part of its cross-sectional length relative to the pane surface or via a convex curvature.
  • a spacing system on the opposite side webs 5 for the glass panes 2 there is in each case a curved or angled transition 12 from which to the outside with formation of the wedge-shaped cavity 9 from the surface of the web 7 and the web region 8 also from the surface of the window.
  • a point-shaped or line-shaped contact along the side webs 5 can practically be formed, while in FIG. 6 a flat contact on the web area 8 is shown.
  • the transverse web 4 facing the space between the panes is offset to the outside with respect to the edge 13 of the profile 1 facing the space between the panes and via an inner web 14 with the edge 13 and the web area 8 serving as an attachment.
  • this inner cross piece 4 is located approximately in the contact area of the panes 2 and can counteract corresponding compressive forces better and also facilitate bending of the entire spacer profile 1 in the corner areas of a frame bent from this profile 1.
  • the cross-sectional length of the spacing web area 8 can be approximately two thirds of the cross-sectional length of the web length 7 delimiting the wedge-shaped sealing space 9 and can be, for example, two millimeters long.
  • the wedge-shaped cavity 9 then extends over approximately three millimeters, which results in a total cross-sectional length of the side web 5 of approximately five millimeters.
  • the wedge-shaped cavity 9 can expand from its starting point to approximately one to five tenths of a millimeter, preferably approximately two tenths or three tenths of a millimeter. This results in a very flat and narrow wedge-shaped cavity 9 with a correspondingly low need for sealing compound, but which nevertheless has a relatively large cross-sectional length overall, that is to say effectively prevents the penetration of moisture, especially since the diffusion width is very small in the desired manner.
  • the distance of the contact area 8 of the web resting against the pane 2 from the inner web 14 which is bent inwards relative to it can be approximately one tenth to two tenths of a millimeter. Since there is such a distance on both sides, a correspondingly high degree of flexibility can be provided within the spacer profile 1, which can absorb a first pressure of the two disks 2 towards one another elastically before an extrusion of the sealing material from the cavity or the opposite movement becomes significant.
  • the outer transverse web 3 - and also the transition web 10 - are covered in the use position with an elastic seal 15 which fills the groove-shaped space between the two individual disks 2 on the outside of the hollow profile 1. 4 and 5, this sealing compound 15, due to its own elasticity, can follow the respective flow movement of the permanently tough elastic sealing material 6 to a certain extent, that is to say in the event of a deformation of the two disks towards one another and a corresponding distance from them 4, not only is the sealing material 6 drawn more strongly into the then widening wedge-shaped cavity 9, but the sealing follows this retraction with a corresponding indentation 16 on its outside. Conversely, when the two panes bulge with the result of the pane edges approaching, sealing material is pressed out of the now narrowing cavity 9, which leads to bulges 17 on the outside of the sealing compound 15 according to FIG. 5.
  • an elastic, adaptable, high-efficiency seal is achieved with relatively little sealing material 6, in which the sealing material can follow the pane movements well without getting into the space between the panes.
  • This is favored by the already mentioned web areas which are in direct contact with the individual disks 2 and which can be moved resiliently in relation to one another and away from one another, provided the distance to the inner web 14 and the inner cross web 4 is present.
  • the spacer profile 1 for insulating glass panes is a hollow profile, in particular filled with desiccant, with two transverse webs 3 and 4 transversely to the plane of the pane and with two side webs 5 running parallel to the plane of the pane.
  • the side webs 5 have contact areas 8 directly adjacent to the panes 2 and towards the outside Disc level a level difference.
  • This level difference is formed in that the side webs 5, starting from their contact area 8 or also a contact point 12, at least over a part of their cross-section continuously and backwards to form a wedge-shaped cavity 9 with respect to the inner surface of the pane, this wedge-shaped cavity 9 with sealing material 6 is filled, which can be moved back and forth depending on the movements of the panes and changes in the wedge shape of the cavity without being able to get into the space between the panes.
