Definitions

  • the invention relates to a spacer profile for insulating glass panes, consisting of a hollow profile, in particular filled with desiccant, which is delimited by two spaced-apart transverse webs running transversely to the plane of the pane and by side webs running approximately parallel to the plane of the panes, the side webs serving in some areas as an attachment for the individual panes and are provided with a sealing material that remains permanently tough and the area of the side webs that has the sealing material has a level difference compared to the contact area of the side webs that is in direct contact with the disks.
  • Such a spacer profile is known from DE-PS 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 sealant requires a relatively large amount of sealant because the entire groove cross section is filled with it must become.
  • 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, particularly in the case of constantly changing deformations of the panes, in which the sealing compound is not always moved back and forth only at the outwardly directed opening gap, but also reaches the contact area or the inside of the pane.
  • the spacer profile of the type mentioned at the outset is characterized in that the side webs of the hollow profile, starting from their contact area, at least over a portion of their cross section, continuously recede towards the outside to form a wedge-shaped cavity and that the wedge-shaped cavity is filled with sealant.
  • the cross-sectional width of the seal is kept narrow at this point 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 achieved with a correspondingly good tightness.
  • the disks can carry out the movements already mentioned, to which the sealant can adapt in the best possible way by either pushing them outward more by the narrowing of the wedge-shaped cavity or by sucking them back without higher pressures within the sealant due to an increasingly narrow outlet gap arise that could lead to a transition into the interior of the space between the panes.
  • Another important advantage is that when pressing the surface covered with the sealing compound with the panes, only relatively low pressing pressures are required, because the sealing compound can deliberately escape into the widening wedge-shaped cavity, so that it has no tendency to do so towards the "wrong" side, namely to press the space between the panes.
  • An inclined transition web can be provided in each case between the outside transverse web and the side webs, and the wedge-shaped cavity can extend to the beginning of this oblique transition web.
  • Such oblique transition webs have proven themselves in the case of spacer profiles of the type mentioned above, especially for those cases in which these spacer profiles are bent in the corner regions of the spacing frames.
  • space is created for an edge sealing compound in this way.
  • the sealing compound protrudes beyond the wedge-shaped cavity towards the outside of the insulating glass pane and extends to the transition web or covers its inside beginning.
  • the cross-sectional length of the sealing compound can be increased further and an even better adaptation to pane movements can be achieved because an even larger supply of sealing compound is then available for the reciprocating movement in the case of the pane 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 to 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, while maintaining the aforementioned advantages of a good and constant adjustment, any 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 cross web or the outer edge of the window.
  • the sealing material cannot overcome such a small and barely 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 compound is passed 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 or swing the curvature or change of direction, so that the contact point may even move more inwards or outwards depending on the deformation of the pane. The less the tendency of the sealing material 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.
  • Fig. 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 13, which allow a limited elastic flexibility at the contact areas in spite of the transverse web located in the contact area.
  • a spacer profile, designated 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 - running transversely to the plane of the pane and by approximately parallel to the plane of the plates, 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.
  • This level difference is formed in that the side webs 5 of the hollow profile starting from their contact area 8 At least over a portion of their cross-section outwards, i.e. towards the crosspiece 3, continuously recede to form a wedge-shaped cavity 9 with respect to the pane surface or plane, the wedge-shaped cavity 9 being filled with the sealing compound 6 in the position of use according to FIGS. 2 to 6 .
  • a transitional crosspiece 10 which slopes obliquely at a relatively large angle of, for example, 45 degrees, until the wedge-shaped cavity 9 extends to the beginning thereof.
  • sealing compound 6 protrudes beyond the wedge-shaped cavity 9 towards the outside of the insulating glass pane and extends to the transition web 6 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 compound 6 , a 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 sealant, so that even with the extreme pane movements according to FIGS. 4 and 5, a transition of sealant 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.
  • the wedge-shaped cavity is thus 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, which connects 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 on 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 is in this case a curved or angled transition 12 from which to the outside with formation of the wedge-shaped cavity 9 from the pane surface 7 and the web region 8 also from the pane surface.
  • a point-shaped or line-shaped contact along the side webs 5 can be practically formed, while in Fig. 3 u. 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 relative 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 crosspiece 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 regions 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 large 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, sealing compound is pressed out of the now narrowing cavity 9 with the result of the pane edges approaching, which leads to bulges 17 on the outside of the sealing compound 15 according to FIG. 5.
  • 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 lying directly on the panes 2 and towards the outside Disc level a level difference.
  • This level difference is formed by the fact that the side webs 5, starting from their contact area 8 or also a contact point 12, at least over a portion of their cross-section continuously and backwards with the formation of a wedge-shaped cavity 9 with respect to the inner surface of the pane, this wedge-shaped cavity 9 with sealing compound 6 is filled in, 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.
