Definitions

  • the invention relates to a method with the preamble of the claim 1 specified characteristics.
  • the semi-finished insulating glass pane has one through the outside of the spacer and bounded by the two glass panels, open to the outside Edge joint, which is subsequently filled with a pasty sealing compound which is usually one of two mixed together Components existing plastic mass, which hardens and thereby creating a firm bond between the glass panels.
  • a pasty sealing compound which is usually one of two mixed together Components existing plastic mass, which hardens and thereby creating a firm bond between the glass panels.
  • curing Sealing compounds are common, but also polysulfides (thiocols) Polyurethane.
  • Butyl rubbers are a material for thermoplastic spacers (Polyisobutylene) in use.
  • Insulating glass panes are also known, in which one between the glass panels Rung frame is inserted to give the impression of a rung window.
  • the frame-shaped spacer is made of hollow metal profiles formed, which is coated on both sides with a thermoplastic adhesive and glued in this way to the two glass sheets of the insulating glass pane become.
  • the spacer and the rung frame form one unit: the prefabricated one
  • the rung frame becomes mechanical with the prefabricated spacer frame connected, namely in that from the outside of the spacer frame screws or nails are driven into plastic end pieces, which are provided at the ends of the rungs of the rung frame.
  • this measure leads to a reduction in the quality of the insulating glass panes, because at the openwork points of the spacer frame the desired one double sealing of the window interior is no longer provided.
  • thermoplastic spacer frame is not economical Prefabricate the way, connect with a prefabricated rung frame, Handle without deformation and then self-adhesive on a glass sheet can be applied. Also the way, first the thermoplastic spacer to extrude onto a glass sheet, a dimensionally prefabricated rung frame and insert it by driving in nails or screws with the Connecting the spacer fails because the freshly extruded, soft spacer has far too little mechanical stability and strength to provide such Endure measure.
  • a rung frame for single-glazed windows is known from US Pat. No. 3,381,431, which is anchored in the window frame by means of sliding tips.
  • a method with the features of the preamble of claim 1 discloses the DE 195 33 854 C1. This document has shown a possibility of how insulating glass panes with frame-shaped, thermoplastic spacer and insert Rung frames can be produced economically without the spacer becoming wavy.
  • the rung frame is not made using the frame-shaped thermoplastic Spacer, but fixed separately from this on the glass sheet.
  • a rung frame is used, the rungs of which are thinner are the specified distance between the glass sheets of the insulating glass pane and end pieces that are either as thick as the given distance or compressible and are somewhat thicker than the specified distance between the glass sheets; the Length of the rungs including their end pieces will be somewhat smaller, preferably 1 to 2 mm smaller than the light measured along the rungs Width of the frame-shaped spacer extruded onto the glass sheet, before it is compressed by pressing the semi-finished insulating glass pane becomes; in addition, the end pieces of the rungs are at least on one of the both sides of the glass facing adhesive.
  • the present invention has for its object to show a way how to insert a rung frame into the insulating glass pane can be.
  • the invention one works with moving the end pieces along the Sprouts. This makes it possible to determine the length of the rungs including their end pieces to choose first much smaller than in the prior art, so that the lattice frame with more scope and therefore lighter in the Spacers bounded area can be used. Then you have Gap between the spacer and the end pieces by the later The spacer cannot be closed, according to the invention instead, the end pieces after inserting the rung frame to close the gap to the spacer. In the advanced Position, the end pieces are fixed and not only the end pieces, but the lattice frame is fixed overall.
  • the method described here makes it possible to use a frame with a to place much larger play, up to the cm range, on the glass plate, which leads to a simplification of the insertion process.
  • gaps between the rung ends and the Spacers can be closed by moving the end pieces.
  • the displacement route the end pieces are expediently at least 2 mm however, preferably 4 mm or more.
  • the displacement of the end pieces is done in such a way that penetrate the spacer without deforming it.
  • the penetrating parts the end piece are preferably cut, pins, spikes or teeth trained and make a positive connection between the end piece and the spacer.
  • the penetration may only happen to the extent that the, when pressing the two glass sheets to the insulating glass pane, in Connect the spacers that extend in the direction of the end piece to the end piece the spacer may not cause wrinkles or waves.
  • centering elements to be attached to the glass panels. This happens, for example, in that the centering elements are glued to the glass panels, but preferably in that the centering elements are designed as suction cups and at Pressing the glass panels to the insulating glass pane pressed against the glass panels become. It is also possible to combine the two types of fastening, namely to use suction cups, which are then glued to the glass panels become. This gives you a very good position fixation of the rung frame regarding the two glass panels.
  • both individual Rungs understood as well as cross-linked sprouts. If the rungs are connected crosswise, the positive Connection between end piece and spacer fixation of the rung frame make it even safer. The positive connection is particularly important between end piece and spacer but with individual horizontal ones Rungs that are not connected to other rungs. These sprouts can sag due to their own weight within the insulating glass pane, if they are only connected to the two glass panels. For example, happen, that the glue starts to flow because of the temperature inside the insulating glass pane is so high and the adhesive effect is no longer sufficient the weight of the Keep rung. When attaching the rungs to the glass panels using Suction cups can cause the problem that the suction effect is not sufficient to hold the rung in place.
  • the rung frames used in the method according to the invention have End pieces which can be moved along the rung and which provide means are around the end piece in the advanced position opposite the rung to be able to determine. These means are preferably designed such that the end pieces formed barb-like slats or corrugations are a form-fitting engagement with the cutting edge of the rung, if attempted, the end piece is again directed towards the rung push back.
  • End pieces are preferably used which are attached to the outside of the rung are and enclose the rung predominantly or completely. Thereby a good contact between the rung and the end piece is made, which is used for fixing of the advanced end piece is necessary.
  • the end piece is very easy to move to the rung until the snap lock is engaged.
  • known commercial models are provided, e.g. such that two locking fingers with noses in opposite directions in two diagonally cut Can snap undercuts.
  • the advantage of this version entails that the end piece is placed around the rung, but not yet is locked, but only the locking fingers are brought into a position that a Pressure in the direction of these locking fingers allows them to snap into the undercuts. After the end pieces are in the desired end position, only the Insulating glass pane are pressed, the end piece being pressed automatically closes by engaging the snap lock.
  • the rungs are designed so that their width is greater than their height and thus they form a narrow side and a broad side, are more advantageous Way the hinge and the snap lock on opposite Narrow sides of the sleeve attached.
  • the advantage of this positioning is that these two elements elude the eye of the beholder as much as possible, because they are attached perpendicular to the glass panels and therefore one does not look directly at the insulating glass pane.
  • the pod will preferably molded in one piece and provided with a film hinge, because this type of manufacture is inexpensive and simple.
  • the sleeve is designed so that it has a cross-section has constant thickness
  • the end piece is designed so that its cross section, its thickness and width thickened towards the cutting edge of the rung. This has the advantage that the end pieces become wider towards the spacer and when penetrating into them, in that at its end more mass is a more stable connection with the hardening spacer.
  • a hole in one side of the rung through which a Assembly tool can be inserted, which in a row of teeth of the end piece engages and thus the end piece by turning the assembly tool is moved out of the rung.
  • the assembly of an insulating glass pane with End pieces of this type are carried out as follows.
  • the rung frame is positioned as described above, during positioning Centering elements only on the side facing the glass sheet is. If the centering element is a suction cup, then this is pressed down for a preliminary fixation of the rung frame to reach regarding the glass panel. Then using the above Assembly tool the end piece in the direction of the spacer unscrewed until it reaches the desired position.
  • the End piece in the spacer preferably also penetrates the row of teeth into it one and, like the two cutting edges perpendicular to it, serves as Element that forms a positive connection with the spacer.
  • a positive connection in two mutually perpendicular Levels come about, which reinforces the position fixation of the rung leads with respect to the insulating glass pane.
  • An advantageous development of the invention provides that a Stop surface is formed, which is pushed up to the spacer. It indicates the position up to which the end piece in the spacer should be pushed forward because the depth of the cutting edges cannot be seen in the spacer is. Another effect that can be achieved is that an even stronger one Positioning of the rung frame with respect to the spacer is effected. After that the assembly tool is removed from the hole in the rung and in this a centering element attached, which is the same as that on the opposite Scion page. Then the second glass sheet of the insulating glass panes put on and pressed with the prepared part. Doing so the rung again centered between the two glass panels and clamped.
  • centering elements are suction cups, they become additional sucked onto the two glass panels and thus increase the force that the Rung to the insulating glass pane fixed in position. Get an even stronger fixation by using one with two cutting edges as the end piece, which cut into the spacer as described above and with this form a positive bond.
  • Extensions are used that protrude from the end piece in the direction of the spacer.
  • the alignment of the extensions which are preferably designed as a cutting edge is aligned so that it is transverse to the longitudinal direction of the spacer orientate.
  • the penetration of the extensions into the spacer Adhesion between the glass panels and the spacer is not impaired, because the connection is not on the flanks of the spacer used for gluing takes place, but on the interior of the insulating glass pane and the surface of the spacer facing the end pieces of the rung frame. If it is large insulating glass panes, they can individual rungs be so heavy that the anchorages of the end piece in Spacers are not enough to lower the rung between the two To prevent glass panels.
  • a particularly preferred development of the invention provides that the end piece stuck in the rung and designed in the form of a thin-walled sleeve is.
  • the outer shape of the sleeve is expediently designed such that it connects precisely to the inside of the rung. This can be achieved be that a slot in at least one narrow side of the end piece is attached so that the end piece in its original shape is larger than the interior of the rung, however, can be inserted into the rung can that the end piece is compressed. Is part of the end piece in the rung and when the end piece is released, it presses itself as Sleeve-shaped end piece from the inside against the inner surface of the rung.
  • the slot extends from that facing the spacer End of the end piece over two thirds of the length of the narrow side.
  • the tail sleeve is preferably made of metal or plastic and in black color held. But there are also other materials for production, as well as others Color schemes conceivable.
  • the black color is used for the end piece stands out as little as possible from the usually black plastic spacer, when the insulating glass pane is fully pressed.
  • An advantageous option the end piece in its advanced position opposite the rung fix, is the form of barbed corrugations instead of the slats listed above. The mode of operation is the same as for the slats.
  • Centering elements are an advantageous further development of the invention used, which extends transversely to the longitudinal axis of the rung along the broad side of the Extend rung. These can be plate-shaped or wave-shaped his. There are extensions of the plate-shaped centering elements from which are intended to penetrate the spacer and thereby to prevent the rung from sinking in the finished pressed insulating glass pane. These extensions are preferably on the narrow side of the rung Ends of the centering element attached. The further possibility of undulating design of the centering elements makes it unnecessary for additional Attach extensions to this centering element, since the lower ones Half waves of the centering element penetrate into the spacer and thus make it impossible for the rung frame to slip.
  • the end pieces are preferably pushed into the rung frame as far as that they stop until the centering elements at the end of the rung frame stuck in the rung. This makes it easier to put the rung frame in insert the semi-finished insulating glass pane with the extruded spacer. After inserting the rung frame, the end pieces are as far as they will go the centering elements on the spacer are pushed against it, using a suitable tool or hands.
