Definitions

• Insulating glass pane with single panes and with a spacer profile
• the invention relates to an insulating glass pane with individual panes and with a spacer profile, which consists of a hollow profile, in particular filled with desiccant, which seals the edge of the pane interior located between the individual panes and from two spaced apart cross webs running transversely to the pane plane and of side webs running approximately parallel to the pane planes is limited, the side webs serve at least in regions as a system for the individual panes and are provided with a plastic-elastic sealing material and the area comprising the sealing material has a level difference compared to the individual panes, and an inclined transition web is provided between the outside crossbar and the side webs is and wherein furthermore the side webs each have a continuation web beyond the inner cross web towards the inside of the insulating glass pane bears on the inside of the respective individual pane in the position of use.
• Such an insulating glass pane is known from DE 33 37 058 C1 or from EP 0 534 175 B1.
• the extension web belonging to the respective side web widens the contact area on the individual disks and also increases the section modulus of the spacer profile.
• the sealing compound is effective on the side webs, but not on their continuation, that is to say not on the respective continuation web.
• the contact surface provided with sealing compound and thus the sealing surface is limited, which is caused by movements of the individual panes, for example due to wind pressure, temperature influences, installation errors or tolerances in the construction may lead to leaks.
• the relatively narrow seal can be inadequate in particular 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.
• extension webs have a first contact point for the individual pane at a distance from their edge region connected to the hollow profile, and that between this contact point and the edge region connected to the hollow profile between the extension link and the single pane is provided with a space filled with sealing material in the use position.
• the extension webs are also used to be covered with sealing material over at least part of their width, so that the overall width of the area of the spacer profile provided with such a sealing material is correspondingly increased. Nevertheless, practically no sealant can be squeezed out when the individual panes move into the pane interior, because this is at least largely prevented by the first contact point. At most in the event of extreme deformations of the individual panes and thus also the extension webs, the could on the Sealing material located on continuation webs is cut off from the other sealing material located on the side webs and thus enclosed, which in the event of overpressure could possibly lead to a slight, but not disturbing, displacement via the first contact point.
• insulating glass panes can also be adequately sealed which are filled with a gas other than air without this being able to diffuse through the sealing area.
• gas fillings with noble gases for example with argon, krypton or xenon, are thus possible which consist of molecules smaller than air and thus have a higher diffusibility.
• a particularly expedient embodiment of the invention can consist in the continuation web having a spacer, designed as a first contact point, facing the respective individual pane, or a thickening which, compared to the outside of the continuation web, around the space formed between this continuation web and the individual pane and filled with sealing material survives.
• the outside of the extension web could be seen in cross-section under one compared to the respective side web or an imaginary extension of the side web on the side facing the individual pane acute angle or slightly oblique, so that the surfaces of the two extension webs facing the individual disks move away from one another towards their free edges, and the free edge of the respective extension web and / or a thickening arranged there can serve as the first contact point with respect to the individual disk.
• This also ensures that a first contact point of the continuation webs keeps a large part of the width of the continuation web in the normal position of the individual disks so far that the sealing material can be accommodated in between.
• the extension webs can be elastically pivoted against a restoring force with respect to the transverse web and / or with respect to the side webs of the hollow profile, ie are flexible. Forces acting on and moving and deforming the individual panes can thus be cushioned and mitigated, so that glass breakage is largely avoided.
• the elastic compliance can be favored by appropriate shaping and / or choice of material.
• 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 if the extension webs are integrally connected to it.
• the extension webs can be molded on and provided with corresponding thickenings and / or inclined positions and a certain intrinsic 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 extension webs in Direction to the free edge or to the thickening increases at least in regions.
• the elastic resilience of the extension webs can be promoted, since the cross-sectional thickness thus decreases starting from the first contact point in the direction of the cross web of the spacer profile, where the actual pivot axis is approximately arranged.
• the spacer profile has a second contact point for the single pane in the region of the side bar or the edge of the extension bar facing the side bar, which comes into contact with the single disk when the extension bar is pivoted elastically and which is opposite the side bar extending from it the individual pane protrudes less than the first contact point in the area of the free edge of the extension web when the extension web is not deformed.
• the extension webs which first form the sole direct contact point of the spacer profile on the individual panes, because their first contact points form the greatest width of the spacer profile in the undeformed state, can yield and be pivoted towards one another until the individual panes also come into contact with the cross bar at the second contact point. Excessive movement of the individual disks towards one another in the transverse direction is thus limited by the crosspiece of the hollow profile or the transverse forces that occur are at least largely introduced into the crosspiece of the spacer profile.
• the crossbar running in the region of the second contact point with its cross section transverse to the individual disks has at least one target kink.
• the crossbar can also give way a little to avoid breaking a single pane, whereby the compressive forces can then also be distributed over the outer crossbar of the spacer profile.
• the predetermined kink of the crossbar can be formed by reducing its cross-sectional thickness and / or a groove, groove or similar weakening of material running between the side bars. It is advantageous if the desired kink on the crosspiece is designed and arranged in such a way that it can be deformed or deflected into the interior of the cavity of the hollow profile. The buckling or yielding of the crosspiece can then be restricted to such a degree by a desiccant filling that the spacer profile continues to function.
• the second contact points on the extension webs can lie in a plane running transversely to the individual panes, which roughly corresponds to the outside of the crossbar facing the pane interior in the undeformed state or in the direction is spaced towards the inside of the pane and away from the hollow profile.
• the crossbar facing the inside of the pane which should be slightly arched or buckled under high pressure loads, is thus slightly offset to the outside in relation to the points exposed to the pressure loads, so that it can accordingly only escape outwards into the cavity of the hollow profile.
• the crossbar can also have a pre-shaped cross-sectional shape, at least in some areas directed into the interior of the hollow space of the hollow profile, or favoring yielding in this direction, for example a partial cross-sectional reduction, shaping, curvature and / or curvature in this direction.
• a material weakening arranged approximately at the height of the cross bar for example a groove or the like running in the longitudinal direction, can be provided, the boundary facing the extension bar as an elastically acting pivot bearing for the Serves extension web and which is filled in particular with sealing material.
• the groove or groove or the like arranged in the region of the transverse web can be connected to the intermediate space located between the extension web and the respective individual pane.
• the sealing material located there can at least initially deflect into the groove or groove before this path for the sealing material is blocked or interrupted by the individual disk striking the second contact area in the event of even greater deformation. Then, however, a larger part of the sealing material is already pressed out, so that squeezing out towards the inside of the pane is largely excluded.
• a further expedient embodiment of the insulating glass pane and, in particular, its spacer profile can consist in the fact that the side webs - for example in the manner described in EP 0 534 175 B1 - in particular, starting from the second contact point, recede at least over part of their cross-sectional length with respect to the side pane and one with it in particular, form a wedge-shaped cavity with an acute wedge angle for receiving the plastic-elastic sealing material and if the wedge-shaped cavity is directly or indirectly connected to the intermediate space between the extension web and the respective individual pane.
• an elastic sealing compound is arranged in the area of the transition webs and / or the outer transverse web, which supports the edges of the two individual panes together with the spacer profile and the cavity for the plastic-elastic sealing material to the outside covered and locks. Due to its elasticity, this sealing compound can contribute to absorbing movements of the individual panes and, in particular when the insulating glass pane is installed horizontally, can ensure the best possible pressure and load distribution, that is to say avoid point loads would break a glass. In addition, of course, the sealing of the insulating glass pane is increased by such a sealing compound and the sealing material that remains plastic-elastic is encapsulated and sealed off from the outside.
• FIG. 1 shows a cross section of the edge region of an insulating glass pane according to the invention with individual panes and an extruded spacer profile, which is a hollow profile filled with desiccant, which has two spaced-apart transverse webs running transversely to the plane of the pane and two side webs running parallel to the plane of the panes Serve system for the individual panes and are covered with a sealing material that remains plastically elastic, the side webs being extended towards the inside of the pane by extension webs, whereby the area covered with sealing material is widened, since these webs are spaced apart from their edge area connected to the hollow profile by a first 1 Have a contact point for the individual panes, 2 shows a representation corresponding to FIG. 1, the extension webs being pivoted inwards by pressure forces occurring transversely to the individual disks, so that a second contact point in the region of the internal crossbar has come into contact with the individual disks,

• FIG. 6 shows a representation of the arrangement corresponding to FIG. 2 in FIG. 5, so that the side windows have pivoted and deformed the extension webs towards one another due to loads or compressive forces occurring transversely to them and, in addition, these transverse forces cause the transverse web closer to the interior of the window arched towards the interior of the hollow profile and supported there by the desiccant, and
• Fig. 7 shows a cross section of several roll-formed spacer profiles stacked one on top of the other.

• the distance between the individual panes 2 is maintained with the aid of a spacer profile 3, which consists of a hollow profile filled with desiccant 4 and which closes the inside of the pane 5 located between the individual panes 2, that is to say the space between the individual panes 2.
• This hollow profile or spacer profile 3 is delimited in both exemplary embodiments by two spaced-apart transverse webs 6 - outside - and 7 - inside - extending transversely to the plane of the pane and by side webs 8 running approximately parallel to the plane of the pane, the side webs 8 being described in a manner to be described below

• extension webs 11 can be pivoted elastically against a restoring force with respect to the inner cross web 7 and thus also with respect to the actual side webs 8 or with respect to their edge region 12 connected to these webs, which is the case when comparing FIG. 1 with FIGS 3 on the one hand and when comparing FIG. 5 with FIG. 6 on the other hand. If inadvertently high static pressure forces or loads occur on the individual panes 2 in the transverse direction, the individual panes are moved slightly relative to one another, which can be compensated and compensated for by the elasticity of the extension webs, so that such transverse loads are reduced and glass breakage is avoided. Such transverse movements can also occur dynamically, for example with wind forces.
