Description

The present invention relates to the technical field of blocking glued external glazing, for example of plastic such as PVC. The invention relates to a particular designed for this area glazing block. The invention further relates to a method for producing this glazing block.

The technique of structural bonding of glass is used today for the manufacture of windows and door panels with a frame made of wood, metal, in particular aluminum, PVC or mixed variants. In the case of PVC frames, the stability of the frame is increased by the injection of adhesive between the perimeter of the double or triple glazing and the rabbet base. Uniform and uniform play is achieved by placing glazing blocks (for example of 4 mm thickness).

It is known in the art of structural glazing to perform an automated (robotic) bonding on the entire periphery of the glazing, for example by means of a two-component adhesive. During the period of bonding and cross-linking, it is therefore necessary to fix and center the glazing while respecting the glazing clearance.

In addition to the possibility of automated production, structural glazing offers further advantages: a narrower frame, thus a larger glass surface and better thermal insulating properties, mechanical stability, wing stiffness, burglar resistance, reduced glass breakage and less maintenance over the lifetime.

The document EP 1 659 254 B1 describes as prior art a window or door leaf, which consists of a profiled frame having a fold for receiving a glazing. The fold has a circumferential surface which, leaving a gap at the front side, the insulating glazing comprises, and a curved surface which covers the lateral edge of the insulating glazing. The insulating glazing is held in the fold by means of at least one adhesive layer. At least one centering element associated with the profiled frame engages the aforesaid circumferential gap perpendicular to the plane of the wing (it may be a rib coextruded with the gap), so that the insulating glazing substantially penetrates as it enters the gap centered in the interior of the wing is arranged. After installation of the insulating glazing in the profile, the circumferential gap is at least partially filled with adhesive. The bond is thus asymmetric at the edge of the glazing. In the document DE 20 2005 016 949 U1 Among other things, the installation of a wedge between the inside of the insulating glazing and the outer surface of the fold is described. This wedge is provided with transverse channels, which allow the penetration of the adhesive.

There are also various models of wedges or spacers or spacers known to hold glazing in the frame of doors or windows (see, for example, the documents EP 0716 206 B1 . DE 199 20 866 A1 . FR 2 778 942 A1 ).

In more specific terms, the document describes EP 1 843 003 A2 a glazing block for glued glazing, one side facing the glass in use and one side facing the glazing rebate. On the fold side cavities are provided to receive the adhesive. Springing material sections limit the cavities. These resilient elements can be present in different configurations.

According to a first embodiment, an elongate plate is placed under the edge of the double glazing, this plate being extended by bridges (or ribs) which are inclined and which are not arranged in the same plane as the plate. This oblique shape serves to facilitate the introduction of the glazing block, when the glazing and the adhesive are already incorporated. It is doubtful that these ribs take over a support function for the glazing; they rather serve to ensure the spring force of the glazing block. During installation, the ribs and the support feet deform and are squeezed together by the pressure of the glazing in the rebate.

Other embodiments are proposed in which the spring elements both on the glass side and on the folded side in the form of a corrugated plate, as spaced transversal tubes are formed with elliptical cross section or have the shape of transverse scales with a cross section in the form of a circle segment ,

This technique is suitable for sequentially centering the glazing in the fold, then gluing and then positioning the glazing blocks. This is due to the fact that one wants to avoid the displacement of the adhesive in the final positioning of the glazing blocks, since the adhesive is not yet polymerized at this time. If, on the other hand, you want to position the glazing blocks before gluing, this will be the case this approach the problem of the absence of the adhesive at the locations where the glazing blocks are arranged.

The object of the present invention is to avoid the disadvantages of the prior art.

In particular, the invention has the goal to allow a definitive Verklotzen and centering of the double glazing in the fold before bonding, wherein the bonding is to be automated.

It is also an object of the invention to provide special glazing blocks which enable the glazing blocks to be arranged in advance.

A further object of the invention is to find a solution in which the glazing block has a shape which does not disturb the gluing process, since this takes place at least at the edge of the glazing on the inside of the glazing.

• • an einer Längsseite der Platte eine rechtwinklige Lasche;
• • an einer der Seite, die zur Verglasung hin angeordnet ist, gegenüberliegenden Seite eine elastische Zunge, die sich über mindestens einen Teil der Länge des Verglasungsklotzes erstreckt und die ein Ende, das an der gegenüberliegenden Seite befestigt ist, sowie ein freies Ende aufweist.

A first subject of the present invention relates to a glazing block comprising:

• A side in the form of a plate intended to be placed on the side of the glazing;
• • on one longitudinal side of the plate, a right-angled flap;
• • On one side facing the glazing, opposite side has a resilient tongue extending over at least part of the length of the glazing block and having an end fixed to the opposite side and a free end.

• • an der Längsseite der Platte, die der Lasche gegenüberliegt, mehrere Querrippen, die voneinander beabstandet sind;
• • das freie Ende der elastischen Zunge ist zu der gegenüberliegenden Seite hin gekrümmt;
• • die Anzahl der Querrippen beträgt drei, wobei zwei der Querrippen an den Längsenden des Verglasungsklotz angeordnet sind und eine der Querrippen zwischen diesen angeordnet ist;
• • die Lasche ist mit einem doppelseitigen Klebeband bedeckt;
• • die Zunge ist so ausgebildet, daß sie sich bei der Montage unter Druck der gegenüberliegenden Seite nähern kann.

• • the flap is covered with a double-sided adhesive tape;
• • The tongue is designed so that it can approach the opposite side under pressure during installation.

Thus, the present invention is to provide cavities that enable the adhesive to be accommodated while the glazing block is installed, thus avoiding the relocation of the glazing block. Furthermore, the provision of spring elements on the glazing blocks aims to clamp the glazing in the rebate. The most important technical problem that is solved with the invention is the improvement of the distribution of the adhesive after the introduction of the glazing blocks.

A second object of the present invention relates to a wing of a window or door having a profiled frame provided with a fold in which an insulating glazing is arranged, wherein the glazing is glued in the fold so that the adhesive over the entire circumference of the glazing fills a gap between the edge of the glazing and the Falzgrund. This gap has at least one glazing block as described above, with the tab and the transverse ribs holding the glazing on the outside and inside, the height of the glazing block being reduced by squeezing the tongue in the rebate.

The 1 shows several views of a particular embodiment of the glazing block according to the invention, including a view of the arranged between the fold and the glazing glazing block in the frame of a door or a window.

The present invention relates to a glazing block, to a frame in which this glazing block is used and to a method of finally botching and centering the glazing in a PVC rebate.

The inventive method provides that during the preparation of the glazing first glazing blocks are arranged on the glazing, which are provided for example with double-sided adhesive tape. This prior placement of the glazing blocks makes it possible to save the manual jamming step and to robotize the entire gluing assembly process.

Several views of the glazing log 1 According to the invention as well as the positioning of the same in a fold of PVC are in 1 shown.

• • eine allgemein längliche Form, die eine Platte 2 umfaßt, welche auf der Kante der (doppelten) Verglasung 7 angeordnet wird;
• • voneinander beabstandete, in der gleichen Ebene wie die Platte angeordnete Rippen 3 an einer der Längsseiten der Platte, die sich über die gesamte nominale Breite der Isolierverglasung erstrecken und die dazu dienen, die optimale Zentrierung der Isolierverglasung (doppelte oder dreifache Verglasung) im Falle einer schlechten Fluchtung der Scheiben, aus denen sie besteht, sicherzustellen. Die sehr dünnen Rippen 3 dienen nicht dazu, die Verglasung abzustützen und sind optional;
• • eine rechtwinklige Lasche 4 an der gegenüberliegenden Längsseite der Platte, die es ermöglicht, den äußeren Rand der Verglasung abzustützen;
• • eine elastische Zunge 5 an der Seite der Platte, die derjenigen gegenüberliegt, welche die Verglasung aufnehmen soll und die sich vorzugsweise über die gesamte Länge des Verglasungsklotzes 1 erstreckt. Die Zunge oder der Lappen 5 ist erfindungsgemäß ein flaches Element, das sich in Längs- und Querrichtung des Verglasungsklotzes 1 erstreckt, um ein gewisses Tragvermögen aufzuweisen. Die Zunge 5 könnte sich nur über einen Teil der Länge des Verglasungsklotz 1 erstrecken oder diskontinuierlich ausgebildet sein. Wenn der Verglasungsklotz 1 nicht verwendet wird, beträgt der größte Abstand zwischen der Zunge 5 und der Platte 5,5 mm. Zusammengequetscht (Anordnen des Verglasungsklotz 1 zwischen der Verglasung 7 und dem Falz 6) reduziert sich der Abstand aufgrund der elastischen Eigenschaften der Zunge 5 auf ungefähr 3,5 bis 4 mm. Die Zunge 5 endet transversal in einem freien Ende 8, das leicht gekrümmt ist, um das Einführen des Verglasungsklotzes 1 in den Falz 8 zu erleichtern;
• • eventuell die Anordnung eines doppelseitigen Klebebandes auf der Seite der Platte oder der Lasche, die der Verglasung gegenüberliegt, welches eine Vormontage (nicht dargestellt) ermöglicht.

The technical characteristics of this glazing block are the following:

• • a generally oblong shape, which is a plate 2 which is on the edge of the (double) glazing 7 is arranged;
• • spaced-apart ribs arranged in the same plane as the plate 3 on one of the long sides of the panel, which extend over the entire nominal width of the insulating glazing and which serve to ensure optimum centering of the glazing (double or triple glazing) in case of poor alignment of the panes which make it up. The very thin ribs 3 do not serve to support the glazing and are optional;
• • a right-angled tab 4 on the opposite longitudinal side of the plate, which makes it possible to support the outer edge of the glazing;
• • an elastic tongue 5 on the side of the plate opposite to that which is to receive the glazing and preferably over the entire length of the glazing block 1 extends. The tongue or the flap 5 is a flat element according to the invention, extending in the longitudinal and transverse direction of the glazing block 1 extends to have a certain buoyancy. The tongue 5 could only be over part of the length of the glazing block 1 extend or be discontinuous. When the glazing log 1 is not used, the largest distance between the tongue 5 and the plate 5.5 mm. Squeezed (arranging the glazing block 1 between the glazing 7 and the fold 6 ) reduces the distance due to the elastic properties of the tongue 5 to about 3.5 to 4 mm. The tongue 5 ends transversally in a free end 8th which is slightly curved to allow insertion of the glazing block 1 in the fold 8th to facilitate;
• Possibly the placement of a double-sided adhesive tape on the side of the plate or tab opposite the glazing which allows pre-assembly (not shown).

• • eine Vorbereitung der Verglasungen, wobei die Verglasungsklötze mit Hilfe eines doppelseitigen Klebebandes vorpositioniert werden;
• • eine Verklebung über den gesamten Umfang der Verglasung, insbesondere auf der inneren Scheibe der doppelten oder dreifachen Verglasung.

The specific assembly procedure provides:

• • a preparation of the glazing, whereby the glazing blocks are pre-positioned by means of a double-sided adhesive tape;
• • Gluing over the entire perimeter of the glazing, especially on the inner pane of double or triple glazing.

It should be noted here that the outer side of the insulating glazing is that which is arranged on the outside of the apartment and the inner side of the insulating glazing is the one which is arranged on the inside of the apartment.

• • die Form des Verglasungsklotzes stört nicht beim Verkleben. Die Festigkeit kann sehr einfach insbesondere durch eine durchgehende Zunge erreicht werden, die nicht den späteren Durchgang des Klebstoffes blockiert wie dies bei der EP 1 843 003 A2 der Fall ist;
• • die Zungen ermöglichen es, eine schlechte Zentrierung im Fall von nicht fluchtenden Scheiben der doppelten oder dreifachen Verglasung und folglich ein Problem beim Verkleben zu vermeiden,
• • die schräge Form der Zunge mit dem leicht nach oben gekrümmten freien Ende erlaubt ein leichteres Einführen in den Falz;
• • die Federfunktion wird durch den Verglasungsklotz wahrgenommen, der eine elastische Zunge aufweist. Diese Vorgehensweise erlaubt die Vereinfachung des Falzes, welcher somit kostengünstiger herstellbar ist.

The glazing block according to the invention has in particular the following advantages:

• • The shape of the glazing block does not interfere with bonding. The strength can be very easily achieved in particular by a continuous tongue, which does not block the subsequent passage of the adhesive as in the EP 1 843 003 A2 the case is;
• The tongues make it possible to avoid poor centering in the case of non-aligned panes of double or triple glazing and consequently a problem in gluing;
• • the oblique shape of the tongue with the slightly upwardly curved free end allows easier insertion into the fold;
• • The spring function is perceived by the glazing block, which has an elastic tongue. This approach allows the simplification of the fold, which is thus cheaper to produce.
