Definitions

  • the present invention relates to a spacer for spacing glass panes in an insulating glass unit, having a dimensionally flexible, elongated base body which extends substantially along a longitudinal direction which is parallel to the spaced to be held glass panes in the assembled state, wherein the base body has two side faces Anlange on the glass sheets and transverse to the side surfaces has a substantially longitudinally extending bottom.
  • the present invention further relates to an insulating glass unit having at least two glass panes and such a spacer which spaces the glass panes and seals the space between them.
  • Spacers of this type are used in particular for multi-pane insulating to allow a spaced connection of the individual glass panes.
  • such a spacer is used to seal the resulting between the glass panes gap, so that a gas introduced in this space can not escape.
  • the spacer should prevent moisture from penetrating from the outside into the gap, as this would otherwise lead to fogging of the disc.
  • Rigid spacers are usually made of a dimensionally stable, closed hollow profile made of aluminum, in which a desiccant (usually granulated molecular sieve) is filled.
  • a perforation in the aluminum profile ensures the exchange of air or gas between the interior of the insulating glass unit and the desiccant filled in the spacer.
  • the aluminum profile is very thermally conductive. This not only counteracts the thermal insulation function of the insulating glass pane, but can also lead to unwanted moisture deposition in the immediate area around the spacer, when at low outdoor temperatures, the inner pane strongly cools.
  • these rigid profiles have the disadvantage that they can be used only for simple glass geometries due to the relatively low elasticity of the aluminum. An adaptation of a rigid spacer to round or more complex glass geometries is associated with very great effort, but sometimes not possible.
  • Such a spacer is for example from the US 4,831,799 A known.
  • the spacer shown therein consists of a strand-shaped thermoplastic elastomer, which with several moisture-impermeable films is laminated.
  • the moisture-impermeable films serve as water vapor and gas diffusion barrier.
  • such a flexible spacer due to its metal-free construction has much better thermal insulation properties and also acts as a sound insulation. Its shape-flexible structure also allows it to be easily adapted to a wide variety of glass geometries, for example also to round insulating glass panes.
  • the spacer Since during assembly of the insulating glass unit, the spacer is unwound as strand material from a storage roll and is unrolled for bonding along its contact surface piece by piece on the glass, the spacer is exposed during assembly large bending stresses. These bending stresses often lead to unwanted microcracks in the thin metal foil, which in turn significantly worsens the water vapor and gas diffusion tightness.
  • the provision of a thicker and structurally reinforced Although aluminum or stainless steel layer would counteract the formation of microcracks, but this would increase the stiffness of the spacer so that it could no longer bend.
  • the spacer would therefore no longer be suitable for the assembly method described above, since it (due to its excessive rigidity) when glued to the glass could not be rolled piece by piece on this. Therefore, the micro-cracks in the metal foil resulting from the assembly had previously been tolerated in the case of such form-flexible spacers.
  • the present invention is therefore based on the object to provide a dimensionally stable spacer of this type, which compared to the above-mentioned prior art has improved water vapor and gas diffusion tightness and yet is suitable for the assembly method described above.
  • a plate-shaped blocking element which serves as a water vapor and gas diffusion barrier, wherein the plate-shaped blocking element has a transversely oriented to the longitudinal direction corrugation.
  • the inventors have recognized that the flexural elasticity of the water vapor and gas diffusion barrier element can be increased many times by transverse corrugation oriented transversely to the longitudinal direction. Under such a corrugation is understood according to the invention a wavy ausgestalteter longitudinal cross-section of the locking element, which is for example generated by the fact that the locking element between two corrugated rollers or gears is rolled. This results in the plate-shaped blocking element a corrugated metal-like shape. On a special geometric shape of this corrugation does not matter for the functioning of the corrugation according to the invention.
  • the blocking element can optimally adapt to the shape of the spacer when bending the spacer
  • the spacer and thus also the plate-shaped blocking element bent during installation transversely to the longitudinal direction to install the spacer piece on the disc piece by piece, so the corrugation of the locking element acts similar to the folds of a concertina, when they are pulled apart or compressed.
  • the plate-shaped blocking element is thus easier to bend due to the corrugation.
  • the main part of the bending stress that occurs is taken up by the compression or expansion of the individual corrugations, without resulting in greater tensile stresses within the material itself.
  • the inventors decided, however, for another way and sought a way that allows them to continue to use the materials previously used for the blocking element while still guarantee the necessary flexibility for the assembly of the blocking element can. This led them to the solution according to the invention of developing a spacer with a corrugated blocking element. It has been found that such corrugation oriented transversely to the longitudinal direction substantially increases the flexibility of the blocking element. This is, as already mentioned, for the assembly and subsequent use of the spacer of immense advantage.
  • the plate-shaped blocking element consists of metal, in particular of stainless steel, or of plastic.
  • the plate-shaped blocking element By aligned transversely to the longitudinal direction corrugation of the plate-shaped locking element so now also relatively thick stainless steel or plastic layers can be used as a water vapor and gas diffusion barrier.
  • Such thick stainless steel or plastic layers have a significantly higher density than those previously Water vapor and gas diffusion barriers used thin plastic or aluminum foils.
  • a further advantage of using stainless steel is the fact that the coefficient of thermal conduction of stainless steel is about 10 times smaller than that of aluminum.
  • the use of plastic is even more advantageous in terms of thermal insulation properties, since plastics or polymers have an even lower coefficient of thermal conductivity.
  • the increased flexibility of the barrier element which is caused by the transversely oriented to the longitudinal direction corrugation, thus allowing not only use thicker and structurally reinforced water vapor and gas diffusion barrier elements, but also to produce them from less ductile but better thermal insulation materials than stainless steel and plastic.
  • the main body of an elastoplastic material in particular of silicone, ethylene-propylene-diene rubber (EPDM), an EPDM mixture, a thermoplastic elastomer (TPE), a TPE-silicone mixture, or of another elastomer in which a desiccant is embedded for receiving and physically binding water.
  • EPDM ethylene-propylene-diene rubber
  • TPE thermoplastic elastomer
  • TPE-silicone mixture elastomer in which a desiccant is embedded for receiving and physically binding water.
  • the materials mentioned are not only optimally suited due to their good deformability, they are also heat-, light-, UV- and ozone-resistant, so that the excellent insulation properties of these materials are permanently preserved under a wide variety of weather conditions.
  • spacers made of such materials In contrast to rigid spacers made of aluminum, spacers made of such materials also look much more visually appealing.
  • the above-mentioned materials can even be dyed color-resistant during production, depending on customer requirements.
  • the possibility of embedding the desiccant directly into the base material of the spacer proves to be the greatest advantage.
  • the desiccant can thus be embedded in the production of the body in this.
  • the desiccant is therefore ideally distributed over the spacer, so that in the later installed state of the spacer water vapor can be absorbed on the entire circumference of the insulating glass unit.
  • a subsequent filling of the spacer with desiccant, as is the case in the production of rigid spacers, can also be omitted here. This saves a whole step and thus reduces production costs.
  • recesses are provided on both side surfaces of the base body, which are filled in the assembled state for additional sealing with butyl. Due to its elastoplastic material properties, the basic body adapts ideally to the surface of the glass panes and seals the insulating glass unit very well. Nevertheless, such so-called “butyl bags” substantially improve the sealing properties of the spacer. They prevent the diffusion of water vapor or gas at the interface between the spacer and the glass pane.
  • insulating glass units with more than two glass panes are frequently used in practice.
  • a spacer is provided for each space.
  • two full-length spacers are needed, which Not only reflected in additional material costs, but also requires several steps.
  • At least one receptacle for a further glass pane is provided on one on an upper side of the base body, which is opposite the underside.
  • a 3-pane insulating glass unit can therefore be assembled only with a spacer.
  • the two outer discs are glued as usual with the side surfaces of the spacer and the third, middle glass pane can be inserted into the receptacle provided for this purpose at the top of the body.
  • the 3-pane insulating glass unit can thus be provided in only one step with only a single spacer. This not only saves material but also production costs.
  • an adhesive strip is provided, which extends substantially in the longitudinal direction and serves for fastening of the spacer to a glass pane.
  • said adhesive strip By means of said adhesive strip, the spacer can be very easily and quickly connected to the glass pane. A separate application of adhesive at the junction, can thus be omitted. This considerably simplifies both automated and manual assembly of the insulating glass unit.
  • the adhesive strip is configured as a double-sided adhesive tape, which has a carrier element, in particular of a plastic film, wherein the underside of the carrier element is glued to the side surfaces and the top of the carrier element in the non-assembled state by a Covering, in particular made of plastic, is covered.
  • the support element is thus similar to a double-sided adhesive tape provided on both its upper and its underside with an adhesive layer. But according to the invention it is also possible to use a carrier element which is provided only on its upper side with an adhesive layer. The support element is glued in this case in the preparation of the spacer with a mechanically applied adhesive directly to the main body of the spacer.
  • the carrier element itself serves primarily for mechanical stabilization of the adhesive layer. Another function of the carrier element is the separation or separation of the possible different adhesives on the top and bottom sides of the adhesive strip. It also serves to ensure that different adhesives can be used for both sides of the adhesive strip, without them mixing with each other. In the unassembled state, the adhesive strip, more precisely the upper side of the adhesive strip, is covered by a covering element.
  • the adhesive tape is not covered in the assembled state by a cover, in particular made of plastic, which has a transverse to the longitudinal direction aligned corrugation.
  • the said cover of the adhesive strip is a so-called "liner", which usually consists of a thin plastic film.
  • the corrugation of this liner which is oriented transversely to the longitudinal direction, thereby has a very similar function as the above-mentioned corrugation of the water vapor and Gasdiffusionssperrelements.
  • the spacer is produced as a strand-like material and is wound onto a storage roll before being mounted for storage
  • the cover element (liner) is subjected to greater bending stresses in the same way as the water vapor and gas diffusion barrier element. These bending stresses easily lead to detachment of the liner, which can not only lead to contamination of the adhesive strip underneath, but also cause adjacent strands of spacers to stick to one another on the storage roll or strip off the liner from one another.
  • the corrugation of the liner according to the invention causes, similar to the corrugation of the locking element, that the liner is easier to transverse to the longitudinal direction can bend, without this dissolves due to the bending stresses occurring from the main body of the spacer.
  • the bending stresses occurring during winding onto the storage roll can be absorbed by the corrugation of the liner.
  • the corrugation is simply pulled apart or smoothed at the outer radius of curvature and compressed at the inner radius of curvature. Since the liner has a larger surface area due to the corrugation, the liner can optimally adapt to the curved shape of the spacer wound on the storage roll without the liner detaching. This prevents the unwanted contamination of the adhesive strip during storage or that already on the storage roll adjacent strands stick together.
  • the above-described corrugated cover member of the adhesive strip can also be used in spacers, in which the water vapor and gas diffusion barrier element itself has no corrugation.
  • the invention therefore also relates to a spacer for spacing glass panes in an insulating glass unit, having a dimensionally flexible, elongate base body which extends substantially along a longitudinal direction which, in the mounted state, runs parallel to the glass panes to be kept at a distance, wherein the base body has two side faces for attachment to the glass sheets and transversely to the side surfaces has a substantially extending longitudinally underside, wherein on the underside a blocking element is arranged, which serves as a water vapor and gas diffusion barrier and on the side surfaces in each case an adhesive strip is provided, which is substantially extends in the longitudinal direction and is covered by a detachable cover, in particular made of plastic, wherein the releasable cover has a transversely oriented to the longitudinal direction corrugation.
  • a Caesarsverêtungs Mrs is provided, which extends substantially in the longitudinal direction and serves to improve the adhesion of the adhesive strip on the base body.
  • a adhesion improving layer is provided on the underside of the base body, which serves to improve the adhesion of the plate-shaped locking element on the base body.
  • this adhesion-improving layer is coextruded with the base body.
  • the adhesion-promoting layer is bonded to the base body by means of a coextrusion process.
  • Coextrusion means in this sense the merging of similar or foreign plastic melts. This results in a positive or cohesive connection between the base body and adhesion enhancement layer.
  • the main body usually consists of silicone, rubber compounds are suitable, which can be easily combined with silicone and also provide a particularly good adhesion for adhesives, especially as adhesion enhancement layer. Examples of such materials are Vamac ® or silicone EPDM.
  • the exact form of the adhesion enhancement layer is not important. It can be attached to the main body both in strip form, in points or in any other pattern.
  • the described adhesion improving layer can also be used in spacers in which the water vapor and gas diffusion barrier element and / or the covering element for covering the adhesive strip have no corrugation (as described above).
  • the invention therefore also relates to a spacer for spacing glass panes in an insulating glass unit, having a dimensionally flexible, elongate base body which extends substantially along a longitudinal direction which, in the mounted state, runs parallel to the glass panes to be kept at a distance, wherein the base body has two side faces to the Anlange to the glass panes and across to the side surfaces a lower side extending substantially in the longitudinal direction, wherein on the underside a blocking element is arranged, which serves as a water vapor and gas diffusion barrier, wherein on the underside of the base body between the base body and blocking element additionally an adhesion enhancement layer is provided, which extends substantially in the longitudinal direction and serves to improve the adhesion of the plate-shaped locking element on the base body.
  • a barrier element in particular of a thin plastic film is provided. This can also serve as additional water vapor and gas diffusion barrier. Due to its large-area bonding good adhesion can be achieved with the existing mostly silicone body.
  • the barrier element may be formed in one piece, so that a single plastic film covers both the side surfaces and the underside of the base body in one piece. On the other hand, it is also conceivable that separate plastic films are used for the side surfaces and the underside of the body.
  • the barrier element is preferably made of a polyethylene terephthalate film (PET film), since the surface of such a film can be very easily bonded. Due to the good adhesion of such PET films, the blocking element, which is usually made of stainless steel, can be glued very easily with inexpensive fast hotmelts. In addition, conventional double adhesive tapes can be used with the aid of the barrier element on the side surfaces of the basic body. Thus, the barrier element not only improves the reliability and durability of the spacer, it also allows the use of cheaper adhesives. It should also be mentioned that the barrier element can be used both as an alternative to the adhesion-promoting layer described above, as well as in combination with this.

  • the main body 12 of the spacer 10 in this case has a receptacle 56 arranged on its upper side 26 into which an additional third glass pane 30 "can be inserted, since the main body 12 is made of an elastoplastic material, this additional receptacle 56 can be used easy to make.
  • the receptacle 56 is dimensioned so that when inserting the glass pane 30 "creates a press fit.
  • the spacer 10 shown here is thus suitable for use in multi-pane insulating glass units.
  • a design only suffices for a single spacer for spacing three glass sheets 30, 30 ', 30 ". but also production costs Fig. 9 a 3-glass insulating glass unit is shown, it is understood that in this way also insulating glass units can be made with more than three panes of glass.
  • the remaining structure of the spacer 10 corresponds to the structure already described in relation to the embodiments 1 to 3.
  • an adhesion improving layer 58 improves the adhesion effect of the adhesive tape 48 and the plate-shaped barrier member 46, respectively, thereby securely preventing peeling of the adhesive tape 48 and the plate-shaped barrier member 46, respectively. It does not depend on the shape of the adhesion enhancement layer 58. It can be both strip-shaped also selectively, as well as in regular and irregular intervals on the base body 12 may be appropriate.
  • the adhesion improving layer 58 can be used both with spacers which are provided with a corrugated plate-shaped blocking element 18 and a corrugated covering element 50, as well as with spacers which have an unraveled plate-shaped blocking element 46 or an unraveled covering element 54.
  • Fig. 12 shows in contrast to Fig. 10 an embodiment of the spacer according to the invention with a corrugated plate-shaped blocking element 18 and a corrugated cover 50.
  • the adhesion enhancement layer 58 serves to improve the adhesion effect of the locking member 18 and the adhesive strip 48.
  • the adhesion enhancement layer 58 may consist of a variety of materials. Since the main body 12, as described above, usually consists of silicone, rubber compounds are suitable, which can be easily combined with silicone and also provide a particularly good adhesion for adhesives, especially as adhesion enhancement layer 58th
  • the adhesion enhancing layer 58 may also be coextruded with the chassis 12. During production, the adhesion improving layer 58 is then bonded to the base 12 by a coextrusion process. This results in a positive or cohesive connection between the base body 12 and adhesion enhancement layer 58. Such a positive or cohesive connection is in Fig. 11 shown in a schematic way. Connecting elements 60 provide here for a connection of adhesion improving layer 58 and body 12. These connecting elements 60 are intended to illustrate only the connection in a schematic manner. It goes without saying that there are several connection options here. In addition to cohesive, extruded or vulcanized compounds are here also positive connection, for example in the form of a connector conceivable.
  • Fig. 14 shows yet another embodiment of the spacer according to the invention.
  • a barrier element 62 in particular of a thin plastic film is provided. This can also serve as additional water vapor and gas diffusion barrier. It is understood that the barrier element 62 shown here is exaggerated for illustrative purposes, but in reality is only a thin film.
  • the barrier element 62 may be formed in one piece so that a single plastic film covers the side surfaces 24, 24 'as well as the underside 16 of the base body 12 in one piece. On the other hand, it is also conceivable that separate plastic films for the side surfaces 24, 24 'and the bottom 16 of the base body 12 are used (not explicitly shown here). It should also be noted that the barrier member 62 may be used both as an alternative to the adhesion promotion layer 58 described above, as well as in combination therewith.
  • the plate-shaped blocking element can be made substantially thicker in contrast to the prior art, since it is much better bendable transversely to the longitudinal direction due to the corrugation according to the invention.
  • Such a thicker, plate-shaped blocking element not only has a higher water vapor and gas diffusion impermeability, it is compared to thin films also much cheaper to produce.
  • due to the increased flexibility of the blocking element now also poorly stretchable, hard materials can be used.
  • the corrugation of the liner according to the invention has the same effect.
  • the liner is easier to bend across the length direction, which significantly reduces the risk of liner detachment during storage.
  • the inventors a considerable progress in terms of handling and operation of the spacer succeeded.
  • By providing an adhesion-improving layer it was also possible to improve the connection of the blocking element or the adhesive strip to the base body.
  • the present invention is not limited to the embodiments shown. A variety of other variations is conceivable. In particular, a wide variety of geometric shapes of the main body of the spacer are conceivable, which need not correspond exactly to the shapes shown. The type, size and arrangement of the individual elements of the spacer is irrelevant to the idea of the invention.
