EP1282756B1 - Insulating glass pane with individual plates and a spacer profile - Google Patents

Abstract

A spacer profile (3) has two side pads (8) which are provided permanently with a sealing, plastic and elastic material and comprise continuation pads (11). The continuation pads (11) create, at a distance from their adge area (12) connected to a hollow profile, a first bearing point (13) for the individual plates (2), which is preferably in the form of a spacer or a swelling (15), as well as a clearance (14) located between the continuation pad and the individual plate (2) and filled with the sealing material (9). The continuation pads (11) are elastic and exhibit, in their edge area (12) close to the transverse pad (7), a second bearing point (16), which becomes functional when the side plates (2) are subjected to a load in the transverse direction.

Description

The invention relates to an insulating glass pane with individual panes and with a spacer profile according to the preamble of patent claim 1.

Such an insulating glass pane is made US-A-4,627,263 . Fig. 7 and corresponding description. When compressing the individual disks and when pressing against the spacer profile and under the influence of wind forces, the sealant can be partially pressed into the interior of the insulating glass pane. This leads to unsightly optical edges.

Out US-A-3,280,523 an insulating glass pane of other type is known in which an outer crosspiece engages over the frontal edges of the individual disks and no crosspiece is available as a spacer. The inner edges of continuation webs form contact points for the individual disks, so that under lateral pressure, a portion of the sealant between the frontal edges of the individual disks and this transverse crosspiece is to be pressed. However, if this is prevented by an outer cross-section U-profile, a squeezing is also not excluded to the disc inside out.

Out US-A-5,962,090 is an insulating glass with individual discs and a spacer profile is known, which has no continuation webs. Thus omitted the Advantages of such continuation webs. The area of the seal is correspondingly narrow, which may be inadequate especially if the insulating glass pane is to contain a gas filling with gases which consist of relatively small molecules, such as noble gases, but which are desirable for a good insulating effect of the insulating glass pane.

It is therefore an object to provide an insulating glass of the type mentioned, in which the seal is improved without the dimension of the spacer profile must be increased and without the sealant can be squeezed to a significant extent, in particular in the disc interior, with a too large Movement of the individual disks in the transverse direction can be limited to each other.
This object is achieved with the means and features of claim 1.

In this way, so also the continuation webs are exploited to be occupied at least over part of its width with sealing material, so that the total width of the region provided with such a sealing material of the spacer profile is increased accordingly. Nevertheless, virtually no sealant can be squeezed out during movements of the individual discs in the disc inside, because this is at least largely prevented by the first contact point. At most, in extreme deformations of the individual disks and thus also the continuation webs located on the continuation webs sealing material could be cut off from the other located on the side webs sealing material and thus enclosed, which may be at a slight pressure under certain circumstances, but not could lead to disturbing crowding over the first landing.

Due to the increased area, which is provided by the inventive arrangement with sealing material, and insulating glass panes can be sufficiently sealed, which are filled with a gas other than air, without this could diffuse through the sealing area. In particular, gas fillings with noble gases, for example, with argon, krypton or xenon are possible, which consist of smaller molecules than air and thus have a higher diffusibility.

Due to the second contact points on the spacer profile is achieved in an advantageous manner that at a pressure acting in the transverse direction of the insulating glass initially the continuation webs that form the sole direct contact point of the spacer profile on the individual discs first, because their first contact points in undeformed state, the largest width form the spacer profile, yield and can be pivoted toward each other until the individual discs come to rest in the region of the crossbar at the second contact point. Thus, excessive movement of the individual disks in the transverse direction is limited to one another by the transverse web of the Holprofiles or the transverse forces are introduced at least to a large extent in the region of the second contact point in the transverse web of the spacer profile.

It is expedient if the spacer profile is an extruded hollow profile, in particular made of aluminum or of an aluminum alloy or a roll-formed Hollow profile in particular made of stainless steel sheet and when the continuation webs are integrally connected thereto. Both in an extruded and a roll-formed hollow profile, the continuation webs can be formed and provided with appropriate thickening and / or inclinations and a certain inherent elasticity.

A further embodiment of the insulating glass pane according to the invention and in particular of the spacer profile can consist in that the cross-sectional thickness of the continuation webs increases at least in regions in the direction of the free edge or towards the thickening. As a result, the elastic flexibility of the continuation webs can be promoted, since the cross-sectional thickness therefore decreases starting from the first contact point, in the direction of the transverse web of the spacer profile, where the actual pivot axis is approximately arranged.

It may be expedient if the transverse web extending transversely to the individual disks in the region of the second contact point has at least one predetermined bending point. In extreme pressure loads then the cross bar can give something to avoid a breakage of a single disc, wherein the compressive forces can then be distributed in addition to the outer crosspiece of the spacer profile.

The desired kink point of the transverse web can be formed by a reduction in its cross-sectional thickness and / or a groove extending between the side webs, groove or the like material weakening. It is advantageous if the desired bending point is designed and arranged on the transverse web such that it is deformable or deflectable into the interior of the cavity of the hollow profile. The buckling or yielding of the crossbar can then be limited by a desiccant filling to such an extent that the spacer profile retains its function further.

In order to specify the direction of the curving in or buckling of the transverse web toward the interior of the hollow profile, the second bearing points on the continuation webs may lie in a plane extending transversely to the individual disks, which approximately coincides with the outside of the transverse web facing the disk interior in the undeformed state or in the direction is spaced toward the disc interior and away from the hollow profile. The interior of the disk facing the transverse web, which should be optionally arched or buckled at high pressure load is thus slightly offset from the pressure load points exposed to the outside, so that he also can dodge only outwardly into the cavity of the hollow profile.

Optionally, the crossbar may also have a preformed, at least partially directed into the interior of the cavity of the hollow profile or a yielding favoring in this direction cross-sectional shape, for example, a partial cross-sectional reduction, indentation, curvature and / or curvature in this direction. Even pressure spikes on the individual disks, which may possibly occur on horizontally mounted in the roof area insulating glass panes also by snow loads and the like, so can be coped with, without the individual discs immediately break or damaged in such above-average loads. If it comes to a deformation of the disc interior facing, intended for buckling or buckling transverse web, this is in turn supported by a desiccant, so that the desiccant filling receives an additional function.

A material weakening arranged approximately at the height of the transverse web, for example a groove or groove or the like running in the longitudinal direction, may be provided between the second contact point on the edge region of the continuation web and the side web, the boundary web of which faces the continuation web as an elastically acting pivot bearing for the web Continuation web is used and which is filled in particular with sealing material. As a result, the specific flexibility of the continuation web in the sense of pivoting for the consideration of compressive forces or movements on the individual disks can be improved and the tightness can be increased, whereby at the same time a certain reservoir for sealing material results.

The groove or groove or the like arranged in the region of the transverse web can in this case be connected to the intermediate space located between the continuation web and the respective individual disk. Thus, given a yielding of the side webs of the sealing material located there, at least initially dodge into the groove or groove before this way for the sealing material is shut off or interrupted by striking the single disc at the second contact area even greater deformation. However, then a larger part of the sealing material is already squeezed out so that squeezing out of the interior of the pane is largely ruled out.

Another expedient embodiment of the insulating glass pane and in particular its spacer profile may consist in that the Seitenstege- approximately analogous to in EP 0 534 175 B1 described manner, in particular from the second contact point, at least over a part of its cross-sectional length against the side window and with this form a particular wedge-shaped cavity with acute wedge angle for receiving the plastic-elastic sealing material and when the wedge-shaped cavity with the between the continuation web and the each intermediate disc space is directly or indirectly in communication. Thus, the sealing material can be displaced in movements of the individual slices in its entire width depending on the direction of movement and sucked back, so dynamically adapt to such disc movements, so that the risk is largely excluded that the sealing material is possibly interrupted by such movements in places in the long run. An indirect connection between the wedge-shaped cavity and the distance between the continuation webs and the individual webs is obtained when a groove or groove is disposed therebetween, while a direct connection exists when such a groove or groove is not present.

In the insulating glass pane according to the invention, it may be expedient if an elastic sealing compound is arranged in the region of the transition webs and / or the outer crosspiece, which supports the edges of the two individual disks together with the spacer profile against each other and the cavity for the plastically-elastic sealing material to the outside covered and closed. Due to its elasticity, this sealing compound can help to absorb movements of the individual panes and, in particular, ensure the best possible pressure and load distribution for horizontal installation of the insulating glass pane, thus avoiding point loads that are too great would cause a glass breakage. In addition, of course, the tightness of the insulating glass pane is increased by such a sealing compound and the plastic-elastic sealing material sealed to the outside and completed.

Especially in combination of one or more of the above features and measures results in an insulating glass, in which without enlarging the spacer profile occupied with plastic-elastic seal material remaining surface and thus the seal against diffusion are increased, at the same time absorbed on the individual slices pressure forces graduated and can be introduced into the spacer profile, so that pressure peaks and the risk of glass breakage are largely avoided.

a cross section of several stacked roll-formed spacer profiles.

In the following description of the different embodiments obtained in terms of their function matching parts the same reference numbers, even if they are slightly different shaped or formed.

A whole with 1 designated, in the Fig. 1 and 2 as 5 and 6 respectively in the cross section of its edge region partially illustrated insulating glass is composed of two spaced-apart individual disks 2, which in turn could be laminated glass or even insulating glass panes. The distance between the individual slices 2 is maintained by means of a spacer profile 3, which consists of a filled with desiccant 4 hollow profile and the disc located between the individual slices 2 inside 5, so the space between the individual slices 2, the edge ends.

This hollow profile or spacer profile 3 is limited in both embodiments of two spaced transversely to the disk plane extending transverse webs 6 - outside - and 7 - inside - and extending from approximately parallel to the disk planes side webs 8, wherein the side webs 8 in a manner to be described as serve direct and / or indirect installation for the individual slices 2 and are covered with a plastic-elastic sealing material 9, in the area of the indirect investment of the individual slices 2 takes place under appropriate sealing.

The region comprising the sealing material 9 has a level difference or distance, which is clearly filled by the sealing material 9, as compared to the individual disks 2, as can easily be seen in the figures.

Between the outside transverse web 6 and the side webs 8 extends in the spacer profiles 3 in each case one with its cross-section obliquely arranged transition bar 10, as it for example EP 0 534 175 B1 is known.

The side bars 8 have over the inner transverse web 7 out to the disc interior 5 of the insulating glass 1 towards extending continuation webs 11, which also rest in the position of use on the respective individual disc 2 in the use position directly or indirectly inside and viewed as a continuation of the side webs 8 as belonging to these can be.

These continuation webs 11 have at a distance from their directly connected to the hollow profile edge region 12 a first contact point 13 for the direct support of the corresponding individual disc 2, so that between this contact point 13 and the hollow profile connected to the edge region 12 between the continuation web 11 and the single disc a filled in the use position with sealing material 9 gap 14 is formed, which is clearly in Fig.1 and 5 as in Figure 3 recognizes. At the first contact point 13 so a direct stop of the single disc 2, while in the region of the intermediate space 14 an indirect contact on the sealing material 9 is provided, as is the case in the region of the side webs 8.

In both embodiments, the continuation web 11 has a trained as the first contact point 13, the respective individual disc 2 facing spacer, which is designed as a thickening 15 of the free edge of the continuation web 11 and the outer side of the continuation web 11 to the between this continuation web 11 and the single disc 2 formed gap 14 projects or causes this gap 14.

It would also be conceivable that the cross section of the continuation webs 11 runs somewhat obliquely in such a way that the center planes of the continuation webs 11 towards each other towards the free edges remove.

Namely, it is provided that the continuation webs 11 with respect to the inner transverse web 7 and thus also with respect to the actual side webs 8 or against their associated with these webs edge region 12 are resiliently pivotable against a restoring force, which in the comparison of Fig.1 With Fig.2 and 3 on the one hand and when comparing Figure 5 With Figure 6 on the other hand recognizable. Join the individual disks 2 in the transverse direction in particular unintentionally high static pressure forces or loads, the individual disks are slightly moved to each other, which can be compensated and absorbed by the elasticity of the continuation webs, so that such lateral loads mitigated and glass breakage is avoided. Such transverse movements can also occur dynamically, for example in the case of wind forces.

In the embodiment according to Fig.1 to 4 the spacer profile 3 is an extruded hollow profile, for example made of aluminum or an aluminum alloy. In the embodiment according to the Fig.5 to 7 the spacer profile 3 is a roll-formed hollow profile, for example made of stainless steel, but in both cases the continuation webs 11 are integrally made or connected to this spacer profile 3, wherein in the roll-formed hollow profile corresponding bends this continuation webs 11 analogous Fig.1 and 2 of the EP 0 534 175 B1 form, while in the extruded spacer profile 3, the continuation webs 11 analog DE 33 37 058 C1 have a solid cross section.

In this case, it is ensured in both cases that the cross-sectional thickness of the continuation webs 11 increases in the direction of the free edge and towards the thickening 15, that is to say in the area of the respectively outer non-free edge 12 Continuation webs 11 a smaller cross-section than in the region of the free edge and the first contact point 13. This favors the flexibility and pivotability of the continuation webs 11 around its edge region 12th

In the Fig.2 . 3 and 6 is clarified that the spacer profile 3 in the region of the side bar 8 and the side bar 8 facing edge region 12 of the continuation web 11 has a second contact point 16 for the respective single disc 2, which comes with elastic pivoting of the continuation web 11 with the single disc 2 in touching contact and the relative to the outgoing from the side web 8 or continuation web 11 to the single disc 2 out less than the first contact point 13 in the region of the free edge of the continuation web 11 - in undeformed continuation web 11 - survives. This second contact point 16 thus occurs only in Berührkontkakt with the respective single disc 2, when the continuation webs 11 have given something by lateral forces or compressive loads something. This situation is the one Fig.2 . 3 and 6 represented where the individual disks 2 abut directly due to corresponding loads on both contact points 13 and 16. Although this leads to a short-term constriction and interruption of the layer of plastic-elastic permanent sealing material 9, which is thereby somewhat displaced, as it is in EP 0 534 175 B1 is described, however, the large-area sealing surface is maintained and is restored at a relaxation of the pressure forces without interruption.

To record even higher pressure forces as possible without risk of glass breakage on the individual disks 2, it is ensured that in the region of the second contact point 16 with its cross-section transverse to the individual disks 2 extending inner crosspiece 7 in turn can give something by by himself its cross section bulges or slightly in particular elastic collapses, which means an additional flexibility of the distance profile 3 in the transverse direction. For this purpose, the crossbar 7 is provided with at least one desired to be explained in more detail kink.

In the embodiment according to Fig.1 to 4 This setpoint bending point of the transverse web 7 is formed primarily by a reduction in its cross-sectional thickness in its middle region, namely a groove or groove 17 or the like material weakening extending there. Moreover, he can also have a total of its outer edge regions a smaller cross-sectional thickness, which is limited for example by near-edge recesses 18, which in turn help to favor buckling or buckling of the transverse web 7 to the interior of the hollow profile with a correspondingly strong pressure load. Such recesses 18 are also in the roll-formed hollow profile according to the Fig.5 to 7 provided and recognizable in Figure 6 clearly a curvature of the crossbar 7 to the interior of the hollow profile out. The desired kink point is thus designed, shaped or arranged on the transverse web 7, which is deformable in this in the interior of the cavity of the hollow profile in or deflected, where it is then supported by the desiccant 4 and prevented from excessive buckling, so that he can move back to its original position when a corresponding burden due to the elasticity and the restoring forces.

The second contact points 16 are arranged on the continuation webs 11 in an imaginary, transverse to the individual disks 2 extending plane which coincides with the inside of the disk facing the outside of the inner crosspiece 7 in the undeformed state or even in the direction of the disk interior 5 back and thus of the cavity of the hollow profile is spaced away. With a corresponding pressure force on the second contact points 16 thus resulting leverages that promote the buckling or buckling of the crossbar 7 in the interior of the hollow section in and favor and prevent buckling of the transverse web 7 in the direction of the disc interior 5 out.

This additional flexibility of the spacer profile 3 by a corresponding flexibility of the transverse web 7 is favored in that the transverse web 7 has the already mentioned preformed recesses 18, but also a different cross-sectional shape or necking or a curvature or curvature could be provided in this direction.

Also in the Fig.1 to 3 It can be seen that the crosspiece 7 near these indentations 18 has a larger cross-sectional thickness than in its groove 17 adjacent region, which the in Fig.2 indicated curvature of the transverse web 7 to the interior of the hollow section and against the desiccant 4 favored.

In both embodiments, an indentation 19 or material weakening arranged approximately at the level of the inner transverse web 7 is provided between the second contact point 16 at the edge region of the continuation web 11 adjacent to the inner cross web 7, and a longitudinal groove or groove is provided in the exemplary embodiment. whose the continuation web 11 facing boundary 20 serves as an elastically acting pivot bearing for the continuation web 11 and which is filled with plastic-elastic permanent sealing material 9, so on the one hand promotes the elastic compliance of the continuation webs 11 and on the other hand increases the supply of sealing material 9.

In the case of the roll-formed spacer profile, one of these indentations 19 is formed by the overlapping of the original edges of the sheet-metal strip, from which it is roll-formed Hollow profile exists.

Arranged in the region of the transverse web 7 indentation 19, groove or groove is in both embodiments as long as with the located between the continuation web 11 and the respective single disc 3 gap 14 in combination, as the continuation webs 11 are not elastically pivoted in the transverse direction, which is mainly in Fig.1 and 5 is clearly recognizable. Thus, the sealing material 9 over the entire cross-sectional width of the side webs 8 including their continuation webs 11 is uninterrupted and can at least partially avoid elastic deformation and thereby be pressed into this recess 19.

Analogous to the spacer profiles according to EP 0 534 175 B1 the side bars 8 from the second contact point 16 or the recess 19 on the basis of at least part of their cross-sectional length against the respective side window 2 back and form with this a wedge-shaped cavity 21 with a sharp wedge angle for receiving the plastically-elastic sealing material 9, wherein this wedge-shaped Cavity 21 also with the zwischem the continuation web 11 and the respective individual disc 3 located intermediate space 14 - via the recess 19 - is in communication. In undeformed side bars 8 thus results in a very wide sealing zone formed by sealing material 9, which also prevents diffusion of gases with small molecules, so for example noble gases from the disc interior 5 to the outside. In this case, this wide sealing zone is maintained even if due to transverse loads the continuation webs 11 yield elastically and the sealing zone is temporarily interrupted by the second contact point 16, because it still extends on both sides of this second contact point 16 continues.

In the region of the transition webs 10 and the outer crossbar 6 can be seen in all embodiments, an elastic sealing compound 22, which supports the edges 2a of the two individual disks 2 together with the spacer profile 3 against each other and covers the cavity for the plastically-elastic sealing material 9 to the outside and closes, wherein one recognizes something of this sealing material 9 in the region of the transition webs 10.

The sealing compound 22 thus contributes to the mutual support of the individual disks 2, wherein due to their elasticity at the same time an adaptation to pressure loads and movements of the individual disks 2 together with the described flexibility of the spacer profile 3 are possible.

The Fig. 4 and 7 on the one hand show the spacer profiles 3 with the appropriately shaped and arranged in the manner described above continuation webs 11 and also the ability to stack this spacer profiles 3 space-saving and partially positive fit to each other. For this purpose, also a yielding of the inner transverse web 7 favoring indentation 18 is utilized, which fits on an integrally formed on the outer end of the transition bar 10 elevation 23. The continuation webs 11 engage over the transition webs 10, so that they have a width which corresponds approximately to the projection of the oblique transition webs 10 in the disk plane. Thus, these spacer profiles are also very well accommodated in magazines or storage racks or feeders to bending machines and the like and provide as a stack.

The insulating glass pane 1 with two - if necessary, in turn assembled - single panes 2 has a spacer profile 3 in the form of a filled with desiccant 4 hollow profile, which is located between the individual panes 2 interior, So the disc inside 5 ends at the edge. The spacer profile 3 has two transversely to the disc planes or to the individual discs 2 extending transverse webs 6 and 7 and parallel to the discs 2 extending side webs 8, which are provided with plastic-elastic permanent sealing material 9 and have continuation webs 11, via the inner crossbar. 6 extend in the direction of the disc inside 5 and increase the lateral contact surface for the individual discs 2. This continuation webs 11 have at a distance from their associated with the hollow profile edge region 12 a first contact point 13 for the individual disks 2, which is preferably designed as a spacer or thickening 15 and a gap 14 between the continuation web 11 and the single disk 2 causes, which also with sealing material 9 is completed. In this case, the continuation webs 11 are elastically yielding and have in their crosspiece 7 near the edge region 12 a second contact point 16, which then comes into operation when the side windows 2 are loaded in the transverse direction.

In the Fig. 1 to 3 and 5 and 6 In addition, it can be seen clearly that the sealing material 9 forms a reservoir in the region of the transition webs 10, which can be changed in volume in the case of disk movements caused by pressure loads. If the individual disks 2 pressed together sealing material can be pressed into this reservoir, so the reservoir are slightly increased, while conversely at a return adjustment of the discs 2 back to their old distance, the sealing material 9 back into the wedge-shaped cavity 21, the groove 19 and the distance 14, as far as he had previously been displaced from it.

It is favorable that this reservoir is sealed airtight by the sealing compound 22 and thus not only displacement movements in the direction of the cross section, but also in the longitudinal direction of the spacer profile 3 can take place.

So it is even possible that compressive forces act only on a portion of the spacer profile, for example, on a corner region and the sealing material is then plastically displaced not only in the reservoir, but also in the longitudinal direction of the hollow profile, so that this displaced sealing material 9 at a Slackening of such a too high pressure returns by itself to its original position.

Insulating glass pane according to one of claims 1 to 9, characterised in that the second abutment points (16) are located in a plane extending at right angles to the individual plates (2) which substantially corresponds to the outside of the transverse strips (7) facing the interior (5) of the pane in the undeformed state or is shifted towards the interior (5) of the pane and spaced apart from the hollow profile.
11. Insulating glass pane according to one of claims 1 to 10, characterised in that the transverse strip (7) has a pre-shaped cross-sectional form, directed at least partly into the interior of the cavity of the hollow profile or favouring a yielding in this direction, such as a partial reduction in cross-section, recess (18), curvature and/or convexity in this direction.
12. Insulating glass pane according to one of claims 1 to 11, characterised in that between the second abutment point (16) on the edge region (12) of the extension strip (11) adjacent to the inner transverse strip (7), and the lateral strip (8), is provided an indentation (19) or weakening of the material, for example a longitudinally extending channel or groove or the like, arranged substantially level with the transverse strip (7) on the outside of the spacer profile, the boundary (20) of which, facing the extension strip (11), serves as an elastically acting pivot bearing for the extension strip (11) and which is filled, in particular, with sealing material (9).
13. Insulating glass pane according to one of claims 1 to 12, characterised in that the indentation (19), channel or groove or the like arranged on the outside in the region of the transverse strip (7) is connected to the intermediate space (14) located between the extension strip (11) and the respective individual plate (2).
14. Insulating glass pane according to one of claims 1 to 13, characterised in that the lateral strips (8) are recessed relative to the lateral plate (2), particularly starting from the second abutment point (16), over at least part of their cross-sectional length, and form with said lateral plate (2) an in particular wedge-shaped cavity (21) with an acute angle for accommodating sealing material (9) that remains plastic-elastic, and in that the wedge-shaped cavity (21) communicates directly or indirectly with the intermediate space (14) located between the extension strip (11) and the respective individual plate (2).
15. Insulating glass pane according to one of the preceding claims, characterised in that in the region of the transitional strips (10) and/or the outer transverse strip (6) is provided an elastic sealing compound (22) which supports the edges (2a) of the two individual plates (2) together with the spacer profile (3) against one another and covers and seals off the cavity (21) for the permanently elastic sealing material (9) to the outside.
