EP1659254B1 - Wing for a window or door - Google Patents

Abstract

The door or window wing has a centering element (4b) arranged diagonally to the wing level into the circumferential gap (5). The centering element is placed in such a way that the double glazing (2) has an approximately central adjustment within the wing, when inserted into the notch (4).

Description

The invention relates to a wing for a window or a door with a profile frame, which forms a lsolierverglasung receiving fold, wherein the fold has a the glazing frontally to form a circumferential gap enclosing peripheral surface and the lateral edge of the glazing overarching folding surface and wherein the glazing is held in the fold by at least one adhesive layer.

The adhesive layer is usually located between the end face of the insulating glazing and the opposite peripheral surface of the profile frame, but it can also extend along the side edges of the glazing, because these edges dive into the fold of the profile frame and are thus covered. In principle, the adhesive layer can run in the circumferential direction; but the bonding can also be divided into individual local areas.

The main purpose of the bonding is to firmly bond the insulating glazing to the surrounding profile frame so that the frame is stabilized and stiffened.

Window sash glued with glazing according to the preamble of claim 1 are inter alia by the WO 02/081854 known. In this case, the adhesive layer is injected into the circumferential gap between the end faces of the insulating glazing and the peripheral surfaces of the profile frame opposite thereto, one at the edge of this circumferential gap arranged boundary web ensures that the leakage of the adhesive is braked from the gap.

From the DE 85 34 651 U is a casement, consisting of a wing profile and a room-side plant leg known. In the airfoil is a multi-pane glazing can be used, which is sealed on the room side by a seal between the room-side pane and the plant leg against the interior and the weather by a voltage applied to the weather-side disc seal against outside air. For the installation of insulating glazing, a vapor barrier is first inserted, then the room-side seal is attached and the room-side disc embedded so that the room-side seal engages under the edge of the disc. Subsequently, the middle disc is inserted with the glass spacer and fixed by pressing an anchoring part. Finally, the weather-side disc is glued to the spacer or anchoring part.

The present invention is based on the recognition that it would be desirable to center the insulating glazing in the profile frame so that the thickness of the circumferential gap on all four end sides of the glazing is as equal as possible, that is to say the same possible gluing conditions and correspondingly equal strength are ensured. This also applies when it comes to the gluing of insulating glazing with a curved contour. The desired centering should be realized in the simplest possible way, without complicating the manufacture of the window or door sash.

This object is achieved with a wing according to the preamble of claim 1 by the features of the characterizing part of claim 1.

This has the advantage that the insulating glazing is automatically guided by the oblique centering without additional aids or devices in an approximately central position within the wing. The previously required manual alignment of the glazing within the frame is unnecessary. The assembly is thereby accelerated and a one-sided system The glazing on the frame due to bad judgment or superficial work is excluded.

According to the centering elements are arranged on the profile frame, because then no additional measures to the glazing are necessary. The centering can be extruded together with the profile frame or they are subsequently extruded to the frame. It is also possible that it is the centering element is a separate part that is connected to the profile frame, such as by being clamped or snapped into the frame - similar to what happens so far with the seals that are connected to the Create inside and outside.

A particularly advantageous development of the invention is the at least one centering in the direction of the said peripheral surface of the frame compliant, in particular elastic form. As a result, the manufacturing tolerances can be compensated for both the glazing dimensions as well as the frame dimensions. In addition, it is possible to keep the glazing with a certain elastic bias centrally in the frame, so that they can no longer slip within the frame during transport of the frame in the gluing station as well as during the introduction of the adhesive.

Suitably, the centering elements are attached to the aforementioned circumferential surface of the profile frame, which is opposite to the end face of the insulating glazing. However, it is also within the scope of the invention to position it at another location of the profile frame, in particular at the seaming surface.

The centering element itself can be designed as a circumferentially running, obliquely projecting into the circumferential gap band. Likewise, it may also consist of a plurality of individual spaced-apart centering tongues.

In both cases, the centering element - in an intermediate region or at the free end - have a portion which comprises the extending in the wing plane edge of the insulating glazing. This causes the centering not only the desired centering in the wing plane of the frame, but also perpendicular thereto. In particular, this results in the advantage that the glazing, if it is as usual for bonding horizontally in its frame, with its weight does not strongly compress the lower seal of the frame and is glued in this off-center position. much Stark is compressed and glued in this off-center position. Rather, it is held by the edge of the glazing cross-centering in a defined position perpendicular to the wing plane and thereby results both on the inside of the disc as well as on the outside of the disc a very precise predictable contact pressure on the applied there seals.

If one does not work with individual, distanced centering elements, but with a largely continuous centering element, finally, there is the possibility of using this centering element as a limiting web for an adhesive chamber. You can then work with low-viscosity adhesives without having to fear running out of the circumferential gap.

As the drawings show, the window sash consists of a profile frame 1, an insulating glazing 2 and a cover strip 3.

The profile frame 1 is divided into numerous chambers for stiffening and to prevent convection in a conventional manner and forms a longitudinally continuous fold 4 at the top, in which the edge of the Isollerverglasung 2 protrudes. The front-side edge surface 2a of the insulating glazing extends at a distance from a circumferential surface 4a of the fold 4 parallel thereto, so that a gap 5 running along the edge of the pane is formed there. This gap 5 is according to the design FIG. 1 completely filled with adhesive 6.

Since the profile frame 1 surrounds the glazing 2 on all faces and the glazing is glued locally or continuously with the profile frame 1, a stable bond between the two parts, so that the otherwise necessary Verglotzung as well as an additional stiffening of the profile frame by inserted metal profiles can be waived.

For a solid connection between the profile frame and glazing, the gap 5 on all faces of the glazing should be as similar as possible, so that a sufficient amount of adhesive can be introduced on all sides. This has been achieved by the fact that bel the assembly, which has to imagine with lying profile frame 1 (without cover 3) and glazing applied 2, the operator manually or mechanically ensures that the glazing on all sides about the same depth in the Fold 4 protrudes, so everywhere has approximately the same distance from the peripheral surface 4a. This alignment not only costs time, but also represents a risk of error. According to the invention, this makes it superfluous for one or more centering elements 4b to run obliquely from outside to inside the gap 5, so that they engage in the profile frame 1 when the glazing 2 is inserted come into contact with their frontal edge surface 2a and thereby automatically center the glazing in the frame.

The centering elements 4b have a certain inherent elasticity in order to compensate for dimensional tolerances between the profile frame 1, on the one hand, and the glazing 2, on the other hand.

In FIG. 1 the centering element 4b consists of a continuous lip which is directly extruded during production of the profile frame 1. As a result, the centering element 4b at the same time also serve to close the gap 5 in order to prevent the adhesive 6 from flowing out of the gap.

Alternatively, the centering element 4b may also be a subsequent anextruded centering lip.

After the introduction of the adhesive 6, the cover strip 3 is pressed on the profile frame 1 in a conventional manner, so that the glazing 2 is held between the upwardly projecting leg 1a of the profile frame on one side and the cover strip 3 on the other side of the glazing ,

In the FIG. 2 The design shown corresponds largely to the profile frame described above, so that the same reference numerals are used. The only difference is that here after the onset of glazing a circulating belt 7 is inserted into the gap 5 and only then the bonding takes place. The strip 7 extends at a distance from the centering element 4b, thereby reducing the available for the adhesive 6 depth of the gap 5 and thereby saves adhesive.

In addition, this solution allows to work with a few mutually distanced centering 4b, since the adhesive can not go through to the centering.

FIG. 3 differs from the previously described embodiments in that a centering element 4c is used, which not only rests on the front-side edge surface 2a of the glazing, but overlaps the glazing and runs a bit into the plane of the window sash. As a result, the centering element not only causes the described centering in the disk plane, but also an orientation perpendicular to the disk plane. In other words, the glazing is held in a defined position between the leg 1a of the profile frame and the cover strip 3, so that the seals, which are usually arranged on the leg 1a and the cover strip 3 for glazing, are loaded in a defined manner.

In FIG. 3 the centering element 4c is extruded together with the profile frame 1, whereas in FIG. 4 the centering element 4c has subsequently been extruded - be it as a multiplicity of individual fingers or in the form of successive lip sections which are produced, for example, by stamping or milling.

The design according to FIG. 5 differs from the previous designs in that a separate centering element 14 is used. This separate centering element is locked to the profile frame 1. For this purpose, the peripheral surface 4a has a groove with an undercut into which the foot of the centering element 14 can snap. Incidentally, the centering element 14 may have the same shape as the centering element 4b or 4c described above.

Incidentally, this separate centering element 14 can also be a lip which extends through in the longitudinal direction or individual centering fingers which are latched into the peripheral surface 4a at a distance from one another. Likewise, it may be a continuous band with individual centering fingers.

The FIGS. 6 and 7 show a particularly interesting design. Here, centering elements 24 are provided in the form of individual, mutually distanced fingers. These centering elements 24 are offset relative to the centering elements described above transversely to the wing plane, so that they do not attack on the edge of the end face 2a, but more in the central region. This position allows the adhesive 6 to pass laterally through the centering elements, ie to flow past the centering elements to the left in the drawing and also to produce an adhesive bond between the profile frame and the glazing in the area there. Alternatively, the offset transversely to the wing plane centering elements 24 can also pass in the longitudinal direction.

The centering elements 24 can be extruded together with the profile frame - be it directly in the form of individual centering fingers, be it in Form of a continuous centering lip, which is then interrupted by successive recesses.

Likewise, however, the centering fingers 24 can also be produced by being subsequently extruded or starting from a common strip which, as in FIG FIG. 5 is connected to the profile frame. Last but not least, the centering elements can also be obtained by local punching and bending off the wall of the profile frame.

It is also within the scope of the invention, not to let the centering elements emanate from the peripheral surface 4a, but from a subsequent surface of the fold 4, that is approximately from the folding surface 1b in FIG. 7 , The latter applies in particular when the centering elements are not to be fully acted upon by the adhesive.

A corresponding embodiment is in the FIGS. 8 and 9 displayed. The profile frame 1 has a substantially same cross-section as in the previous designs; However, here a centering element 34 is provided, which does not start from the peripheral surface 4 a relative to the end-face edge surface of the insulating glazing, but instead from the lateral folding wall 1 b. It initially extends obliquely or horizontally into the fold 4, but runs obliquely downwards or outwards in that region 34a which comes into contact with the frontal circumferential surface 2a when the glazing 2 is inserted. As a result, as with the above-described centering elements, an oblique ramp is obtained which, when the glazing is inserted into the sash frame, ensures that the glazing is centered relative to the sash frame.

Of course, it is also possible with the centering element 34, instead of the drawn continuous strip to provide a plurality of spaced apart centering fingers. Likewise, the centering element 34 can still be provided with a stop, as well as in FIG. 3 holding the glazing transversely to the glass plane in a defined position.

In the exemplary embodiment, the centering element 34 is shaped so that its free end, when the glazing presses against the centering element, ends very close to the peripheral surface 4a of the fold 4 or to a wall part adjoining it. As a result, the gap between the end face 2a of the glazing on the one hand and the peripheral surface 4a on the other hand almost blocked at its left end and the adhesive 6 is inhibited from flowing out of this gap, as far as the centering element 34 passes through, so is not interrupted.

In all embodiments, the centering elements have been shown as compliant lips or tabs. Instead, it is also within the scope of the invention to work with individual centering wedges, which are integrally formed on the profile frame 1 or jammed with it, in particular locked. Such centering parts may optionally be formed more or less massive.

As a material for the profile frame is preferably plastic; but there are also metallic materials into consideration.

Regardless of where the centering elements are positioned and how they are structurally configured, there is a summary of the advantage of the present invention is that it can dispense with the previously necessary manual alignment of the glazing within the window or door frame and the glazing automatically when inserted into the frame is moved to the central position.
