Definitions

  • the invention relates to a spacer frame for insulating glass panes made of a hollow profile rod, in the cavity of which granular, hygroscopic material is contained and whose inner wall section has a slit or perforation running in the longitudinal direction of the hollow profile rod, and whose corner areas are cut and made by bending.
  • Spacer frames for insulating glass panes are known in many forms. They are usually made from light metal profiles. The profile strips are cut off according to the side lengths of the frame and then the frame is assembled from these individual profile bars. Separate corner connectors or corner pieces are available for the frame corners (US Pat. No. 3,380,145). It is also possible to have the ends of the individual profile bars butt against each other in the frame corners or to join them together using miter cuts. All profile strips for such frames have in common that they are designed as hollow profiles. The hollow of these profiles is used to hold hygroscopic materials that are available in the form of small beads from relevant companies on the market.
  • This material interacts with the interior of the insulating glass pane in a known manner via the slitting or perforation in the hollow profile.
  • the mentioned corners of the spacer frame whether they are formed by butting the profile bars together, by connecting them in a miter cut or by using corner angles, are so-called weak points in every insulating glass pane, which require particularly careful processing and machining and which nevertheless frequently give rise to problems to make complaints, especially for those panes that are exposed to an extreme atmosphere (for example panes in indoor swimming pools or in workshops).
  • US-PS 3540118 It is also known (US-PS 3540118) to surround insulating glass panes with rounded corner areas on the outside with a U-shaped strip.
  • U-shaped border strip In order to be able to adapt the U-shaped border strip to the rounded corner area, several V-shaped incisions are provided in the cheeks of this cross-sectionally U-shaped strip, so that this U-shaped strip can subsequently be bent.
  • This U-shaped bar is then on the outside of the insulating glass pane and forms an outer frame, so to speak.
  • a one-piece insulating glass frame is also known (DE-OS 2160847), which is bent from an originally straight profile bar.
  • the profile bar With its central cross-sectional area, the profile bar forms a spacer for the glass panes and it has legs on the outside which, together with the central part, limit receiving grooves for the glass panes.
  • This profile strip has approximately a U-shaped cross section and the middle part serving as a spacer is equipped with a central continuous bore.
  • This insulating glass unit is assembled in such a way that the glass panes are inserted into the outer grooves and then the side flanks delimiting these grooves are pressed against the glass pane.
  • This assembly has apparently not been successful in practice.
  • the outer flank webs In order to properly seal the parts against each other, the outer flank webs must be pressed against the pane and pressed against it. This pressing or rolling down the flank webs leads p iben usually fracture of the Sch.
  • To form the spacer frame it was provided in this known construction to cut a continuous profile strip of the type mentioned V-shaped in the corner regions of the frame to be formed and then to bend the individual successive sections against one another.
  • FIG. 1 The edge of an insulating glass pane is shown in cross section in FIG. 1.
  • Two panes 1 and 2 are spaced apart from one another by a frame 3 which is made from a light metal profile 20.
  • the profile 20 shown in FIG. 1 is known per se and is formed by rolling.
  • the wall section 4 of the profile bar 20, which forms the inside of the frame 3, has a slot 5.
  • the side flanks 6 are stepped and thereby taper the profile width in the lower part of the profile bar 20 or on the outside of the frame.
  • a permanently elastic sealant and adhesive 7 is on the one hand on the flanks of the profile rod 20, on the other hand on the glass panes 1 and 2 and ensures a functional bond of these parts.
  • the outer cavity which is delimited by the pane edges and by the outside of the profile frame, is filled with a likewise permanent sealing compound 8.
  • the cavity 9 of these profile bars 20 receives a hygroscopic material 19 which interacts with the interior 10 of the pane via the slit 5 or via a possible perforation in this wall section 4.
  • This hygroscopic material is offered by the relevant industry in the form of small beads. The diameter of these beads is approximately 1 to 2 mm.
  • a profile rod 20 of the length that corresponds to the circumference of the frame to be manufactured is initially selected.
  • the profile bar (FIG. 2) is now cut in the area of the bending points, specifically in that wall section 4 which has the slits 5 or perforations.
  • Several parallel incisions 11 run transversely to the longitudinal extension of the profile bar.
  • Crosspieces 14 remain between the individual incisions 11.
  • the width b of the individual incisions 11 corresponds approximately to the width c of the remaining crosspieces 14.
  • the incision depth is chosen to be somewhat greater than would correspond to the wall thickness s of the profile bar 20.
  • the depth t of the incisions 11 corresponds at least to the wall thickness s of this wall section 4.
  • the sections A and B of the profiled bar formed by such incisions 11 are bent against one another (arrow 12) and thereby a frame corner (FIG. 3) is formed.
  • the outside of the frame deforms not inconsiderably in this corner area (FIG. 5), but it is essential that the side flanks 13 of the profile do not bulge outwards, but remain essentially flat, as extensive tests have confirmed.
  • the corner zones or their flanks 13 can also be carefully guided in a workpiece so that these flanks are reliably prevented from bulging in the corner area.
  • the two outer boundary edges 15 and 16 of these incisions abut one another (FIG. 5) and clamp between them: the webs 14 are positively inserted, an essentially uniform material profile being achieved in the flanks of the corner.
  • Such a frame corner with the position of the deformed incisions is shown in a side view in FIG. 5.
  • the total width B of the incisions (FIG. 4) is chosen to be approximately 6 mm.
  • the incisions are each about 1 mm wide and the webs remaining between them are about 1.5 minutes. This results in a total incision width B of 6 mm.
  • the profile strips can be filled with the aforementioned hygroscopic material before this processing or after cutting.
  • the end sides of the profile are then blocked so that this spherical material cannot flow out.
  • the special shape of the incisions also prevents this hygroscopic material from escaping.
  • the incisions are placed in a section bar cut to length so that in the frame to be manufactured (FIG. 6) the two profile ends 17 and 18 lie in a straight part of the frame to be manufactured.
  • these ends can easily be combined with a suitable coupling or with a suitable adapter.
  • this joint reaches an area of the frame that is easy to control in terms of production technology in the manufacture of the insulating glass pane.
  • the previously so feared weak points in these insulating glass panes are therefore completely eliminated thanks to the invention.
  • the invention also includes other profile shapes, such as are customary for the production of such spacer frames and which also have hollow chambers for holding hygroscopic material.
  • profile shapes are shown in FIGS. 1 to 10, FIG. 7 showing the prepared and FIG. 7 the bent or bent profile piece, and this profile has a simple rectangular cross section. This profile is formed by roles.
  • the starting material for this profile was a flat strip, which was folded into this closed box profile by means of appropriate deflection rollers.
  • FIG. 9 shows a drawn profile with a longitudinal perforation 21, also prepared for the bending process
  • FIG. 10 shows the bent or bent profile.
  • Such profiles generally consist of light metal alloys.
  • the invention is not limited to such lead metal profits, it includes those profiles which are drawn or rolled, for example, from steel.
  • the side flanks remain essentially flat, which is extremely important for these frame profiles, for reasons that have already been explained in the introduction.
  • the outer boundary side is deformed not insignificantly in the corner area, but this does not affect the quality of the frame, on the contrary, this deformation then saves a lot of space in the outer corner area of the pane, which can then be completely filled with sealant, so that the sealing material has accumulated in the areas of increased risk.
