Definitions

  • Spacers for insulating glass panes usually consist of hollow profile bars made of aluminum or stainless steel, which contain a free-flowing desiccant, usually molecular sieves. It is the task of the desiccant to bind existing moisture in the insulating glass, so that the temperatures occurring in the insulating glass does not fall below the dew point.
  • Metallic spacers are today usually bent in one piece from a hollow profile bar, in which the desiccant is already filled. Before bending a corner, the inner wall is notched so that the corner forms exactly at the intended location and has a defined appearance. As inner wall, the interior of the insulating glass pane facing wall of the spacer is understood.
  • the inner wall of the opposite wall of the hollow profile bar is referred to as its outer wall or base.
  • the two walls which connect the inner wall and the outer wall and face each other in the insulating glass their individual glass panes are referred to as the flanks; they usually run mostly parallel to each other, because they must be glued to the glass.
  • the hollow profile bars to be bent are usually connected to one another in succession by straight connectors.
  • the spacers may therefore also contain several straight connectors.
  • Such frame-shaped metallic spacers are characterized by good mechanical stability. However, they have the disadvantage that their production is complicated.
  • spacer frames of metallic U-profiles, thermoplastic full profiles, which are extruded directly onto a glass sheet, and plastic hollow sections are known, which are filled as well as spacers made of metal hollow profile bars with a granular, free-flowing desiccant.
  • Spacers made of plastic hollow profiles have only a low thermal conductivity, so that they hinder the heat transfer between the individual glass panes of an insulating glass in the desired manner.
  • the disadvantage is that hollow profile bars made of plastic can not bend to square frame, if they have the required for use as spacers in insulating glass hardness and strength. This is especially true for hollow profile bars made of glass fiber reinforced plastic.
  • spacer frame made of plastic hollow sections in that you just straight hollow profile sections, which form the legs of the frame-shaped spacers together by inserting elbows of metal in the ends of the hollow profile sections, where they claw barbs.
  • spacers made of metal hollow profile bars by individual hollow profile bars at the corners of the spacer by angle pieces are connected, which have two legs connected by a hinge, which are locked together in a position in which the legs form a right angle with each other.
  • the individual hollow profile bars are first connected in a straight line with each other, provided on their flanks continuously with an adhesive sealant and then formed by pivoting the hollow profile bars around the joint of the respective elbow to form a frame and this by a plugged into the ends of the hollow profile bar linear Plug connector closed.
  • Such a design of the corners leads to unstable distance holders with the disadvantages mentioned above.
  • EP 0 947 659 A2 and EP 1 030 024 A2 to inject into the corner regions of the spacer frame through an opening in one of its flanks a thermoplastic which bridges the corners and the spacer after cooling and hardening of the plastic gives the necessary stability.
  • the disadvantage is that it takes a comparatively long time until the plastic has cooled and solidified.
  • EP 1 030 024 A2 to transfer the spacer being produced into a special hardening zone after injection of the plastic while maintaining the angle of the bent corner. This way of working is time consuming and costly.
  • WO 2006/077096 A1 which discloses a spacer for insulating glass panes, which is produced from a hollow profile bar made of plastic by providing it with a recess at the points provided for the corners, which in each case provides the inner wall and the two Flanks of the hollow profile bar opens, the outer wall but leaves intact.
  • angle pieces are used, which have two legs connected by a hinge and can be converted from a straight-line shape into an angled shape in which they are fixed relative to each other. Such an angle piece is initially positioned in a straight line in the region of the respective corner to be formed. By bending the hollow profile bar, the corner is then formed and stabilized by the angle of each other in their predetermined angular position latching legs of the elbow.
  • the present invention has for its object to show a way how from metallic hollow profile rods, an advanced frame-shaped spacer can be made with curved corners for insulating glass panes, without increasing the cost of insulating glass production.
  • the two flanks of the hollow profile bar are pressed against the point of the hollow profile bar intended for forming the respective corner before it is bent, it can be ensured without further measures that, on the one hand, the inner wall of the hollow profile bar in the area of the corner a defined, reproducible course takes place and that on the other hand, the two flanks of the hollow profile bar are not pressed outwards during bending and / or form wrinkles, the distance between the widen holder in the area of a corner. Rather, excess material of the flanks is forced into the cavity of the hollow profile bar, so that the width of the hollow profile bar does not exceed the original width of the hollow profile bar after bending in the region of the corners.
  • the profile shape of the hollow profile rods according to the invention favors that they can be pressed without the risk of being injured in the region of a corner of the spacer to be bent and then bent. • With hollow profile rods according to the invention, the bending of the corners and the
  • Closing the spacer can be done by hand.
  • the expenditure on equipment that was previously required for the production of metallic spacers for insulating glass panes, can be substantially reduced.
  • the spacer can form a double barrier and thus a double security against the ingress of moisture into the insulating glass pane.
  • Suitable sealing compounds are those which are already known for the bonding and sealing of insulating glass panes.
  • a hollow profile rod is used for the spacer, in which the inner wall and the outer wall are narrower than the hollow profiled rod, so that its flanks have a central portion which is parallel to the surface of the opposite glass sheets, and on both sides of this central portion adjacent have a contrast projecting portion which terminates on the inner wall or on the outer wall of the hollow profile bar, which are narrower than the hollow profile bar overall, which has its greatest width between the central portions of the flanks.
  • a spacer with such a profile can be used very versatile for purposes of the invention.
  • a sufficient amount of desiccant-containing adhesive may be provided which contains sufficient desiccant to fog the insulating glass panel from within during the intended life of more than 20 years, preferably more than 25 years to prevent. This leads to the further advantage that in the cavity of the hollow profile bar no desiccant must be filled, so that it can be bent more easily and with less effort.
  • a primary sealant can be applied to the middle section of the flanks in a thin layer, which contains no desiccant and reliably prevents inward diffusion of water vapor as well as loss of a gas other than air, with which the insulating glass pane can be filled ,
  • a secondary sealing compound may be provided, which binds and creates the permanent mechanical bond between the glass panes and the spacer.
  • the desiccant-containing sealant a primary sealant, in particular based on polyisobutylene, in which the desiccant is incorporated in powder form.
  • a desiccant-free primary sealing compound instead of a desiccant-free primary sealing compound, the same secondary sealing compound can be applied to the middle section of the flanks, which is also provided in the recessed region of the flanks which adjoins the outer wall. • It can be applied to all three sections of the flanks but also a uniform sealant, which fulfills both the task of a primary sealant and the abandonment of a secondary sealant and contains a desiccant at least in the recessed portion of the flanks adjacent to the inner wall.
  • the recessed portions of the flanks not only allow sufficient quantities of primary or secondary sealing compound to be absorbed, but also have the advantage that bending of the individual glass sheets as a result of wind loads, temperature loads and fluctuations of the ambient pressure do not lead to hairline cracks in the sealing compounds, wel - could cause leakage of the insulating glass.
  • the narrow central portions of the flanks constitute a fixed point for the bending movements, which tear most near the inner wall and in the vicinity of the outer wall at the respectively provided sealing compound, but do not lead to cracking in the sealing compound because this is there in such a large thickness that its tensile strength is not exceeded.
  • the hollow profile bar may contain a desiccant when it is bent. In this case, it should be ensured that there is less desiccant in the corner area of the hollow profile bar when bending than outside the corner area. It has a favorable effect that desiccant is forced out of the corner area by the contour of the walls of the hollow profile bar which is formed when the hollow profile bar is pressed in and by the bending process, thereby facilitating the bending process.
  • the hollow profile rod is inserted in an empty state. presses and bent and preferably no drying agent is subsequently filled in the hollow profile bar. This has the advantage that the production of the hollow profile bar can be simplified.
  • the hollow profile rod contains a desiccant, then in the assembled insulating glass pane this must have contact with the air space in the insulating glass pane;
  • the inner wall of the hollow profile bar must be perforated for this purpose.
  • the hollow profile rod is not filled with a desiccant, then the hollow profile rod requires no perforation, but can be produced inexpensively by a simple extrusion process. This is especially important for hollow profile bars made of aluminum.
  • the hollow profile rod can be formed by rolling molds from a non-perforated metal strip; In this case, it has a longitudinal seam, which is expediently secured by welding, in particular by laser welding. The manufacture by roll forming is especially for hollow profile rods made of stainless steel in question.
  • the longitudinal seam is sealed by welding.
  • a closing of the longitudinal seam by gluing is also possible.
  • the hollow profile bar has no opening in any of its walls. This promotes safety against the ingress of atmospheric moisture into the interior of the insulating glass pane, because the walls of the metallic hollow profile bar, which are produced without openings, are diffusion-tight with respect to water vapor.
  • For sealing the insulating glass pane only the gaps between the flanks of the hollow profile bar and the two glass panels of the insulating glass pane have to be sealed with the aid of an adhesive, which is state of the art.
  • the applied on the flanks adhesive sealant is z.
  • a thermoplastic polyisobutylene and is intended to prevent moisture from diffusing through the sealed with the sealant gap between spacer and glass in the interior of the insulating glass.
  • Such a thermoplastic sealant is also referred to as a primary sealant. It is preferably applied after the impressions, but before the bending of the hollow profile bar, essentially over the entire length of the hollow profile bar, including the indented points of the flanks of the hollow profile bar. This has the advantage that the sealing compound is entrained in bending of the respective corner of the inwardly folding portion of the flank and pressed tightly in the fold, so that it can be ensured that no cavities arise in the fold, not with the sealant are filled. By bending arises in the corner region of the spacer, an excess of sealant, which further strengthens the sealing effect in the subsequent pressing of the insulating glass just in the critical region of the corner, which is particularly advantageous.
  • the adhesive sealant is to be applied substantially over the entire length of the hollow profile bar, so it is meant that initially a slight length of the hollow profile bar can remain free of the sealant at the ends of the hollow profile bar. After the two ends of the hollow profile bar are connected by a straight connector, a gap in the strand of the sealant can be closed if necessary by a subsequent application of sealant.
  • the longitudinal seam lies on a flank of the hollow profile rod, then the sealing compound covers the longitudinal seam and seals any leaks in the longitudinal seam. Therefore, the longitudinal seam is preferably located on an edge of the hollow profile bar.
  • the outer wall and the inner wall of the hollow profile rod and a desiccant-containing compound applied to the spacer in each case prevent water vapor from penetrating into the insulating glass pane. In the gap between the glass sheets and the flanks of the spacer holder also prevents the applied there sealant, z.
  • a penetration of moisture over a relatively long diffusion path Nevertheless, should some moisture diffuse through the adhesive sealant, it can still be absorbed by the desiccant which is incorporated into a mass adhered to the hollow profile rod which adjoins the sealant applied to the flanks.
  • TPS material those known in the insulating glass industry as TPS material are known in the art Spacers are extruded in situ onto a glass sheet. Insulating glass panes with such a thermoplastic spacer, in which a powdery desiccant is incorporated, are known under the trademark TPS.
  • the TPS material is a primary sealant based on polyisobutylene with finely divided zeolite powder (molecular sieves) as a desiccant.
  • the sealing compound applied to the flanks and the desiccant-containing mass applied to the hollow profile rod may differ from each other, but may also be the same. Preferably, they are applied in a joint operation synchronously or overlapping in time on the two flanks and on the inner wall of the hollow profile bar. If a thermoplastic "primary" sealant is used to seal the gap between the spacer and the two adjacent sheets of glass, then, because of its thermoplastic nature, it can not provide the necessary bond between the glass sheets and the spacer. In the prior art, the secondary sealing compound is usually filled in an edge joint of the insulating glass pane, which is set back by the two glass panes and those opposite the edges thereof Outside wall of the spacer is limited.
  • the spacer profile When using the spacer profile according to the invention, it is particularly advantageous to concentrate the desiccant-containing composition in the narrower, adjacent to the inner wall region of the spacer profile on the edge and in the adjoining broader area of the spacer profile an adhesive sealant containing no desiccant, in particular a primary sealing To provide mass and / or a setting secondary Verêtlungsmasse, which connects directly to the desiccant-containing adhesive or connect.
  • a secondary sealing compound is expediently provided, which produces the permanent bond between the glass panes and the spacer.
  • the desiccant-containing composition and the non-desiccant-containing adhesive sealant, including the secondary sealant, are preferably applied in a single operation on the flanks of the hollow profile bar.
  • the mass containing the desiccant may be the same mass used as the primary sealant. It is also possible to use the dry weight-containing composition as the primary sealant, if it is sufficiently diffusion-tight, as is the case with the polyisobutylene-based TPS material.
  • the flanks exclusively a sealing compound according to WO 2008/005214 A1 be provided, which combines both the function of a primary and a secondary sealant in itself and additionally contains a desiccant. In this way, one comes with a minimum amount of sealant and with a minimum of mechanical effort.

It should be remembered that under the inner wall of the spacer, the interior of the insulating glass pane facing wall of the spacer and under the outer wall is understood the inner wall of the opposite wall of the spacer. The recessed partial areas adjacent to it are added to the flanks.
  • a hollow profile bar is used, which is formed asymmetrically with respect to its flank intersecting the longitudinal center plane, so that the recesses which adjoin the inner wall are different from the recesses which adjoin the outer wall, and can accommodate different amounts of sealing compound.
  • This has the advantage that with one and the same hollow profile bar spacers can be produced, in which the larger Recesses are provided either adjacent to the inner wall or to the outer wall of the spacer.

  • the desiccant-containing composition If a large volume of the desiccant-containing composition is of particular importance, then it orien- tiert the spacer profile in the spacer so that the larger spaces between the glass panes and the flanks facing the interior of the insulating glass pane. However, if more emphasis is placed on a larger volume of secondary sealant, then it orients the spacer profile such that the larger spaces between the glass sheets and the flanks of the spacer are turned outward.
  • the hollow profile rod which is used for the production of the spacer is expediently designed mirror-symmetrically.
  • the straight hollow profile bar is preferably first pressed in at all points provided thereon, where a corner is to be formed. Thereafter, the adhesive sealant is applied to the two flanks of the hollow profile bar. If the adhesive sealing compound applied to the flanks is not a desiccant-containing composition, a desiccant-containing composition is additionally applied to the flanks of the hollow profile rod. This is preferably done in a single operation by co-extrusion or temporally overlapping; Preferably, the desiccant-containing composition immediately and completely connects to the non-desiccant-containing adhesive sealant.
  • the corners are bent, which can be done by machine, with the least effort but also by hand is possible, since the location and shape of the corners are already predetermined by the previous impressions of the hollow profile bar. Bending can be accomplished particularly easily if there is no adhesive mass on the inner wall and on the outer wall of the hollow profile rod, but only on the flanks. Then, the hollow profile bar can namely be easily gripped on its inner wall and on its outer wall, without touching the mass applied to the flanks, and can then be bent by hand or by machine.
  • a secondary sealing compound is also applied to the flanks of the hollow profile rod before the frame is bent, or a uniform sealing compound is applied which at the same time fulfills the task of primary and secondary sealing compound and preferably also contains the desiccant. Then even the sealing machine for the secondary sealing compound can be saved, which in the prior art - see, for. B. DE 28 16 437 A1 - the most complex machine in an insulating glass production line.

  • hollow profile rods according to the invention are used for the production of spacers for insulating glass panes, in which case both the outer wall and the inner wall wall is narrower than the hollow profile bar overall, so that the flanks spring back to both sides of their flat, central portion, then the formation of cracks in the sealant as a result of changing pressure, temperature and wind loads already with a very thin layer of sealing compound be prevented in the gap between the flat central portions of the flanks and the adjacent glass sheets, namely with a thickness of the sealant of only 0.25 mm to 0.45 mm, preferably only 0.3 mm to 0.4 mm.
  • the present invention is finally an inventively designed hollow profile rod for producing a frame-shaped spacer for insulating glass panes.
  • Hollow spacer frames can be used which are hermetically sealed and contain no desiccant. Such spacer frames are characterized by a particularly low heat transfer coefficient, especially if they are made of stainless steel. Stainless steel stands for long life, is insensitive to UV light, has low thermal expansion and low thermal conductivity, absorbs no moisture and is diffusion-tight.
  • the hollow and hermetically sealed spacer whose cavity acts as a very good insulator, provides a double barrier to the penetration of water vapor.
  • the outer wall of the spacer may be left free of sealant so that the only bridge between two panes of glass of an insulating glass pane is the hollow and empty spacer itself. This reduces the heat transfer between the two glass panes of an insulating glass pane and reduces the risk of condensation forming in the edge region of the insulating glass pane. At the same time results in a more uniform surface temperature of the insulating glass pane. • If any sealant is provided only in the joints between the spacer and the adjacent glass panes, the least amount of sealing compound will be used without compromising the sealing and life of the insulating glass pane. The required quantity of sealing compounds is independent of the width of the spacer!
  • the outer wall of the spacer can be flush with the edges of the glass panels, increasing the clear cross section of the insulating glass panel and reducing the required installation depth into a window frame or door frame. • The outer wall of the spacer can be painted for aesthetic reasons or to protect it.
  • the insulating glass pane can be pressed with a predetermined pressing pressure per running centimeter of the circumference of the spacer in such a way that the sealant on The thinnest point is only about 0.3 mm to 0.4 mm thick, which not only saves sealant, but at the same time increases the resistance to the ingress of water vapor. Stress loads in the sealant can be controlled by increasing the thickness at which the sealant is provided on the flanks of the spacer to the inner wall and the outer wall of the spacer.
