Description

Frame profile, wing of a window or door and method for

Production of the same description Technical field

The invention relates to a frame profile for a window or a door, with a profile surface, which is intended to form a insulating glazing enclosing folding peripheral surface and of which a profile section is perpendicular, which is intended to form a insulating glazing cross-folding surface. It further relates to a window or door leaf and a method for producing such.

State of the art

From EP 1 070 824 A2 it is known to glue the insulating glazing into a fold of the profile frame. For this purpose, along the to

Insulating glazing parallel fold surface of the circumferential Rahmenfalzes an adhesive applied in strips, before the insulating glazing is inserted into the fold. When inserting the insulating glazing is therefore pressed against the peripheral adhesive strip, which takes over the connection between the glazing and the profile frame.

To easily put a laminated glass in a profile frame of a

It is known from EP 1 004 740 A2 to fasten the laminated glass used in a frame rebate with the aid of an adhesive layer which defines the circumferential gap between the window and the window

Laminated glass and the fold fills. So that the adhesive layer on the

End areas of the laminated glass can be limited in the transition region between the peripheral surface of the fold and the

subsequent, the edge of the laminated glass cross-folding surface a profile bar are glued, which limits the adhesive layer.

Applicant's EP 1 373 672 B1 teaches the provision of a

Circumferentially extending boundary web for the adhesive layer, the is arranged at a distance in front of the edge of the insulating glass cross-folding surface and in particular rises from the peripheral surface of the fold.

These known solutions are more or less effective, and in particular the latter has been in mass production of

Insulated windows established. However, the use of increasingly high-quality and multi-layered insulating glazing, which has been adapted to higher environmental standards and tailored to customer requirements, results in higher ones

Demands on the profile shape and frame designs, which the existing solutions do not fully meet.

Presentation of the invention

The invention is therefore based on the object, an improved

To provide a frame profile of the type mentioned above and a correspondingly improved window or door wings. Furthermore, an improved method for producing such is to be shown.

This object is achieved in its device aspect by a frame profile with the features of claim 1 and subordinate by a wing for a window or a door with the features of claim 8 and in their method aspect by a method having the features of claim 12 or claim 15 , Appropriate training of the

Concept of the invention are the subject of the respective dependent claims.

The invention is based on the consideration, the need for frame profiles or frame structures, the more flexible to different

Insulating glazing are customizable, by further development of the

Boundary bridge concept to take into account. It further includes the idea to provide this purpose instead of a single boundary web several webs or lips, which are spaced apart in the transverse or thickness direction of the frame profile and differentiated ways to

Insertion and fixation of differently constructed and differently thick insulating glazings and for the targeted positioning of these

provide adhesive adhesive layer. Furthermore, the invention includes the idea that these webs or lips as from the profile surface, the

Surrounds the front side of the insulating glass to form upstanding elements. In embodiments of the invention, it is provided that the webs or lips rise perpendicular or at an angle in the range between 45 ° and 90 ° from the profile surface.

A further embodiment provides that the cross-section of the webs or lips reduces towards their free ends and / or they are deformable at least at the free ends. Deformability can also be achieved without the aforementioned cross-sectional tapering towards the free ends of the webs or lips, for example by arrangement inclined relative to the profile surface in conjunction with a certain flexibility. However, the mentioned cross-sectional tapering makes it possible, in some applications, advantageously to give the webs or lips an increasing (easier) deformability towards their free end. This in turn makes it possible to insert one into a corresponding profile frame

Insulating glazing even with certain deviations on the one hand relatively easy (namely against low elastic resistance) use and

On the other hand, to prevent excessive displacement of the glazing in the frame when in the standing state (state of use) largely.

In this sense, it is possibly synonymous advantageous that in another

Execution the free ends of at least a portion of the lips are each formed by a single edge and both free surfaces of this lip or lips are curved so that their angle of inclination relative to the

Profile surface is smaller towards this edge.

According to further embodiments of the invention, the webs or lips are formed separately from a different material than the frame profile and molded onto this, glued or via a tongue and groove connection

appropriate. Specifically, in this case, the webs or lips may have an elastomer, in particular be extruded in the same material of an elastomer. It is also possible to put on the profile patch webs or lips in turn composed of several parts or to form from several materials by coextrusion.

In a further embodiment of the invention, in the proposed frame profile at least one web or lip, in particular the / from the furthest spaced, with the tip of an adhesive syringe adapted over the longitudinal extent of the

Frame profiles regularly spaced through holes provided. This allows a "lateral" injection of adhesive into the space between the pierced web or the pierced lip and the adjacent thereto further web or another lip with already inserted insulating glazing However, appropriate filling openings can also during the assembly process immediately before the introduction of adhesive in the outer lip of the then specifically present lip configuration are made.

A formed from the above-explained frame profiles window or

Door leaf is initially characterized by the fact that the insulating glazing is already largely mechanically (and advantageously with a certain elasticity in the direction of the disk plane) held by a plurality of webs or lips rising from the circumferential folding surface already in an adhesive-free state. This has an advantageous effect especially with relatively thick three-pane insulating glazing or sound-insulating or bullet-proof glazing. In the at least partially bonding the

Insulating glazing in the frame is achieved with the profile according to the invention that the glazing is glued into the profile frame, wherein a web or a lip of the or each provided with webs or lips

Frame profile, the extension of an adhesive strip across the

Profile extension limited. Specifically, the adhesive strip or the

Adhesive bead should be placed so that it is bounded by two adjacent webs or lips on both sides. This allows a particularly precise and pollution-free bonding.

In a preferred embodiment from the present point of view, it is provided that the profile frame is formed from four frame profiles of the type proposed and an adhesive strip delimited by at least one web or lip is arranged on each of these frame profiles. But there are also realizations with only one profile part according to the invention or two such profile parts possible, the remaining profile parts of

Frame then have a conventional structure.

Process-side embodiments of the invention will become apparent in

Substantially substantially according to the above device aspects, so that these will not be repeated here. It is, however, again pointed out that two different from the end

Method guides are possible, wherein the first provides an adhesive entry after insertion of the insulating glazing in the fold of the profile frame and the second one precedes the onset adhesive entry into the web or lip structure of the frame.

In the first-mentioned embodiment, the adhesive is most easily sprayed onto the uppermost web or the uppermost lip and thus bounded on one side by this. As the uppermost lip or uppermost lip, irrespective of the position of the profile frame, the foremost ridge or lip, i. the farthest from the furthest spaced ridge or lip indicates. Somewhat more expensive is an alternative embodiment, in which the adhesive through through holes in the uppermost web or the upper lip between them / these and in the mounting position

underlying web or the underlying lip is injected, such that the adhesive layer at least partially through the uppermost and the underlying web or the uppermost and the

underlying lip is bounded on both sides.

In both basic procedural guides may additionally

Work step be provided with the before the onset of

Insulating glazing in the fold of the profile frame part of the present on the or each frame profile according to the invention webs or lips is removed. Depending on the manner in which the lands or lips have been formed, selective removal can be accomplished by simply peeling or by means of a blade or hot wire, either already on the quasi-endless profile or already for a particular window or door frame cut profile pieces. A tool used for this purpose (with a blade or a heating wire o. Ä.) Can be to facilitate or

Acceleration of this work should be configured so that several lips can be separated in the correct position in one operation.

As a result, either the position of the adhesive layer to be subsequently introduced with respect to the transverse extent of the insulating glazing or the width of the adhesive layer or both can be varied according to the thickness of an insulating glazing to be used or other specific requirements. Specifically, this can be adapted in a single web or lip configuration prefabricated frame profile for very different insulating glazing.

For example, can be realized with the inventive profile frame also a very precise Glaskantenverklebung.

Fig. 1 shows in cross-section the frame region of a window sash 10 with a frame profile 11 and a double-pane insulating glazing 13. The frame profile 11, which may have a basic construction known per se, has a surface adjacent to the front side of the insulating glazing 13

(Peripheral or Falzgrund) I Ia and one of this perpendicular upstanding profile section Ib I, which surrounds the edge of the insulating glazing on the weather side. On the opposite inside of the

Window sash is on the frame section 11 an additional profile part

(Glasstalteleiste) 15 attached, which surrounds the edge of the insulating glazing on the inside of the room. Both between the folding surface I Ib and the insulating glazing facing inner surface of the glass retaining strip 15 and the respective adjacent pane of the insulating glazing is an elastic

Inserted sealing strip 17a and 17b.

From the peripheral surface I Ia of the frame profile 11 are perpendicular to a plurality of narrow webs 11c, which extend parallel to the folding surface I Ib at equal intervals to each other in the longitudinal direction of the frame profile. The webs 11 c are made of a different material later on the frame profile eleventh

applied, z. B. extruded from an elastomer. Between the furthest surface I Ib farthest web 11c and the

Insulating glazing 13 facing inner surface of the additional profile part 15 is an adhesive layer 19 made of an elastic adhesive for fixing the insulating glazing 13 provided in the frame rebate. Their extension is limited by the adjacent web 11c, and the group of webs 11c provides an additional bearing for the insulating glazing 13 and limits positional displacements perpendicular to the circumferential surface of the Rahmenfalzes, the aufgru nd the permanent elasticity of the adhesive layer 19 are basically possible to some extent. Fig. 2 shows in a to FIG. 1 ajar cross-sectional view of a window sash 20 of similar construction, but which contains a three-disc insulating glazing 23 in a slightly wider frame profile 21. With Fig. 1 matching or functionally corresponding parts are with on Fig. 1 reference numerals ajar and will not be explained again here. An essential difference from the aforementioned embodiment is that inclined to the peripheral surface 21a of the fold and the same material formed with the frame profile 21 lips 21c are provided and their number is smaller than that of the webs 11c of FIG. 1 is. Specifically, the lip configuration shown in FIG. 2 may have been created by removing additional lips originally present on a prefabricated frame profile to accommodate the relatively thick disc package 23. The three lips 21c limit the extent of the adhesive layer 29 to the area between the inner and middle pane of the insulating glazing while leaving the area between the middle and outer pane of adhesive free. Furthermore, touching the free ends of the lips 21c here the front side of the glazing and thus support them directly - together with the adhesive layer 29 - in the frame. Due to the inclination of the lips 21c, this support also has a certain (bending) elasticity.

Fig. Figures 3 and 3A show in cross-sectional views as further

Embodiments a frame profile 31 or 3 with a structure that can largely similar to that of the above-described profile 11 or 21, of which but only in the assembled state of the (not shown) facing the upper region with the

Peripheral surface 31a and the folding surface 31b is shown. On the the

Peripheral surface of the glazing-forming surface 31a is provided with a group of lips 31c extruded from an elastomer or thermoplastic, which are slightly inclined with respect to the surface and which leak at their free end into a single boundary edge. Both free surfaces are curved so that the overall result is a layer and shape that provides a stable elastic abutment for the sealed

Slice package of insulating glass can provide. The frame profile 3 according to FIG. 3A differs from the profile 31 shown in FIG. 3 only by a slightly different design of the right corner region, which receives the additional (not shown) glass retaining strip. This modification has some importance for the execution of the step of adhesive entry into the However, the circumferential gap of the insulating glazing is otherwise irrelevant to the invention.

The further frame profile 41 shown in FIG. 4 together with an insulating glazing 43 differs from the one described above only by the smaller number of lips 41c which are provided by the peripheral surface 41a

get up. The smaller number of lips can be realized on the profile from the beginning, but it can also - to adjust the overall stiffness and total elasticity of the rabbet base arranged group of lips - before mounting individual ne lips, for example with a hot cutting wire or knife have been removed. By means of an adhesive layer 49, which is introduced beyond the lip 41c furthest away from the folding surface 41b, a so-called is here (as in FIG. 1). Glaskantenverklebung realized.

The embodiment of FIG. 5 differs from the aforementioned first in that here again - according to the embodiment of FIG. 3 - a larger number of lips present, therefore, therefore, the support of the insulating glazing 53 in the rebate is also basically stiffer.

In addition, here is a so-called. Falzgrund- or Glaskantenverklebung

in which an adhesive layer 59 is provided between the two lips 51c furthest from the outside folding surface 51b. To introduce this adhesive is in the outermost (in the mounting state of the frame to the uppermost) lip 51c a

Through hole 51 d is provided, through which the adhesive metered into the space can be injected, the intimate contact with both the end face of the insulating glass and the rebate bottom comes and the gap between the two outer lips 51 c filled tightly. Fig. 6 shows a modification of the latter embodiment with the

Frame profile 51 according to FIG. 5 matching frame profile 61 (in which only the through hole in the outermost lip is omitted), but in combination with a modified insulating glazing 63. Again, a Falzgrundverklebung by means of a between the two of the rebate 61b farthest lips 61c arranged adhesive layer 69 executed. Due to the fact that the space inside disc of the three-disc insulating glazing 63 is slightly larger than the other two discs, there are here a protruding inner edge 63a of the insulating glass, which presses on the leftmost in the figure on the right lip 61c as the remaining end face of the insulating glazing on the other lips.

As a result, the previously introduced into the space between the two outermost lips adhesive trace 69 is slightly deformed and comes into intimate contact with all boundary surfaces.
