Description

Door, window or building facade element with sealing system

Technical Field

The present invention relates to a door, window or building facade element with a sealing system for a rebated space.

Background

Doors, windows or building facade elements of the above-mentioned type have long been known. An important structural feature of such door, window or building facade elements is the profile beam from which the mullion and/or sash frames are assembled (typically cut at mitred joints). The profile beam is typically cut from a composite profile. A thermally decoupled profile system for door and window structures is then provided by the mullion frame beams and the sash frame beams, the profile system having a sealing system in the rebated space between the mullion frame beams and the sash frame beams.

For this purpose, the composite profile of the frame and/or sash frame beams is formed according to the prior art (and also according to the invention) from at least one outer metal profile, preferably also a middle metal profile and an inner metal profile, which are connected to one another by at least one respective heat-transfer-reducing isolation region, which is formed, for example, from one or more plastic isolation webs.

The gap in the pocket space between the frame and the sash frame is typically sealed with an intermediate seal (intermediate seal system). In this case, for example, large-volume intermediate seals made of co-extruded material with a cavity are known. Another common type of such a seal is known as a stop-seal system, using two relatively small seals on the outer surface of the profile. The thermal insulation of such a solution should further improve or should reduce the heat conduction.

Disclosure of Invention

Against this background, it is an object of the present invention to provide a door or window or a building facade element with a sealing system in the rebated space which ensures particularly good thermal insulation between the spaces separated from each other by the door or window, i.e. in the rebated space.

According to the invention, the sealing system has at least one or two sealing element pairs, which in each case comprise a first sealing element on the frame and a sealing element on the frame, the sealing element pairs together forming at least one intermediate sealing element which sealingly bridges the slot space in the closed state of the wing. The two sealing elements are each fastened to the respective profile by means of a tongue-and-groove connection. The two sealing element pairs are preferably secured in the respective slots of the insulating tabs on the cheek frame rail and/or the fan frame rail.

As a further advantageous feature, at least one of the two seals also has a stop sealing region. Preferably, the stop sealing region is provided on the tab of the sash frame rail (or the cheek frame rail) by a fastening means, such as a tongue and groove connection.

In general, by using one or two seal pairs a sealing system is obtained which can be referred to as a combined single or double intermediate seal and stopper sealing system. The system achieves high tightness and very good insulation.

More particularly preferably, the composite profile system is designed as a "three-layer system" which comprises two separating regions with a double seal pair arrangement. Foamed or unfoamed, with or without cavities, EPDM or TPE or similar plastics (with different shore hardness) are used as preferred materials for making the seal. Multi-zone seals in which the composition of the material (foamed or unfoamed) is produced simply or by coextrusion are also conceivable.

The entire metal profile is preferably produced as an extruded aluminum profile. Alternatively, it is also possible to manufacture from other materials, such as steel, and/or other manufacturing methods.

All the insulating webs are preferably made of a plastic material, for example polyamide (PA66, PA6, PPA), polyester (PET, PBT), polyolefin (PP) or polyvinyl chloride (PVC), so that a large degree of thermal separation between adjoining metal profiles is achieved in each case.

All of the spacer tabs may (necessarily but not necessarily) have at least one cavity. The cavities can also be integrated in each case in the plane of the separating webs by transverse webs into a separating web of a higher level.

The separating webs of the separating web region can advantageously each lie in a plane. This is advantageous because it ensures a clear structure, but is not mandatory.

According to a preferred embodiment, one, more or all of the sealing elements of the pair of sealing elements engage with the sealing foot in the sealing groove of the separating web. This is advantageous because no projection of the separating webs is thus produced in the slot space. In a less preferred embodiment, it is also conceivable for the sealing elements to each have a groove, in which a projecting pin of the separating web engages.

At least one seal of each seal pair has one or more cavities, whereby the thermal insulation is additionally improved.

The invention also provides a pair of seals for a door, window or building facade element according to the invention.

FIG. 2 shows a sectional view of a sash and a cheek frame profile in a closed position of a wing;

FIG. 3 shows a close-up view of the slot space of the arrangement shown in FIG. 2;

Detailed Description

Fig. 1 shows a door 1 with a pivotable and/or rotatable wing with a frame 2, on which the wing is hinged to one or more fittings, and a jamb frame 3. In the alternative to the described door, the invention can also be used in windows or building facade elements or the like.

The jamb frame 3 of the door 1 has

jamb frame beams

4, 5 and 6. The frame 2 of the wing has a vertical frame beam 7 on the handle side and another vertical frame beam 8 on the hinge side. Furthermore, the fan frame 2 has an upper horizontal fan frame beam 9 and a lower horizontal fan frame beam 10. The

frame rails

7, 8, 9, 10 are each combined to form a frame 2, here by means of an angle connection (not shown here), so that a filler, for example a glass window (not shown here), can be inserted into the frame 2.

The

frame beams

4 and 7 of the door 1 are shown in phantom in fig. 2. A slot space F in the form of a gap is formed between the frame beam 4 and the frame beam 7. The gap should be sealingly bridged.

The frame beam 4 has a first metal profile 11 (first outer profile) which is connected to the metal intermediate profile 12 by at least one or more (here parallel-oriented) first separating

webs

13a, 13 b. The

insulating webs

13a, 13b between the first metal outer profile and the metal intermediate profile form a first insulating web region I or insulating web plane in the frame beam 4 of the cheek frame. The second metal profile 14 (further outer profile) is likewise connected to the metal intermediate profile 12 via at least one or more (here parallel) second separating

webs

15a, 15 b. The

insulating webs

15a, 15b between the second metal profile 14 and the intermediate profile 12 form the second insulating web region II or the insulating web plane in the frame beam 4 of the cheek frame. The metal profiles of the frame beams 4 of the mullions have cavities, which is beneficial for thermal insulation.

In fig. 2, two of the insulating tab regions I, II illustratively have such

insulating tabs

13a, 13b on the frame rails of the cheek frames; 15a, 15b, the respective end sections of which are positively and non-positively connected to the associated grooves of the metal profile.

The

other frame beams

5, 6 of the door or window are preferably constructed exactly as the frame beams 4.

The sash frame beam 7 has a first metal profile 17 as an outer profile. At least one cavity 18 is formed in the first metal profile. The sash frame beam furthermore has a second metal outer profile 19, in which at least one cavity 20 is likewise preferably formed. Between the two metal profiles 17 and the outer profile 19, a third metal profile, namely an intermediate profile 21 is arranged, in which at least one cavity 22 is likewise preferably formed. The metal profile 17, the outer profile 19 and the intermediate profile 21 may alternatively be provided without a cavity or with a plurality of cavities in each case. Said cavity reduces, if necessary, the thermal conduction between the spaces adjoining the door or window or the building facade element and allows a simple arrangement of corner connectors or the like.

The first metal profile 17 is in turn connected to the metal intermediate profile 21 via at least one or more (here parallel-oriented) first separating

webs

23a, 23 b. The separating

webs

23a, 23b between the first metal profile 17 and the metal intermediate profile 21 form first separating web regions III or separating web planes in the sash frame beams 7. The second metal outer profile 19 is likewise connected to the metal intermediate profile 21 via at least one or more (here parallel)

second separating webs

24a, 24 b. The separating

webs

24a, 24b between the second metal outer profile 19 and the metal intermediate profile 21 form second separating web regions IV or separating web planes in the sash frame beams 7.

In fig. 2, the insulating web region III of the sash frame beam 7 has insulating

webs

23a, 23b, the respective end sections 25 of which are connected in a form-fitting and force-fitting manner to the grooves 26 of the adjacent metal profiles (outer profile or intermediate profile) in each case, so that a shear connection is produced between the insulating webs and the adjacent metal profiles in each case, in particular also in the Z direction (with reference to the coordinate system in the drawing) or in a direction perpendicular to the cross-sectional plane of the cheek frame profile 4. This connection is also referred to as a shear connection in the following. The connection provides shear strength against forces occurring on the window or door or the like due to expansion.

In fig. 2, the separating

webs

24a, 24b of the second separating web region IV of the sash frame rail 7 between the second metal outer profile and the metal intermediate profile 21 form a separating region between said separating webs and the second outer profile 19, in which the sliding guide without shear forces permits a relative movement. As an alternative, the separation region can also be formed between the separating

webs

23a, 23b and the other metal profile or between the outer profile and the intermediate profile 21. For this purpose, the separating

webs

24a, 24b are connected in a form-fitting manner in the y and x directions (see coordinate system in fig. 2) to the second metal outer profile by means of a pin connection 27. This forms a sliding guide. The shear strength in the sliding guide, which is orthogonal to the cross-sectional plane of the composite profile, can, but need not, approach zero. Such a sliding guide is called a "shear-free connection structure".

The arrangement of the shear-free connection (here in the insulating tab region IV) can be understood by way of example. As an alternative, the shear-free connection is also provided in the separating web region III or in both separating web regions III, IV or is formed in another way. The shear-free connection can also be omitted when the problem of expansion compensation is solved in another way or not.

The sash profile furthermore has a retaining strip 28, by means of which a filler, for example a glass window, is retained.

The insulating tab regions I and II of the mullion section bars and the insulating tab regions III and IV of the fan frame section bars correspond to each other.

In addition, an advantageous sealing system is provided in the gap or pocket space F between the cheek frame rail and the fan frame rail to seal the gap of the pocket space F.

Fig. 3 shows an enlarged view of the slot space F shown in fig. 2 and of the insulation region of the connecting profile system adjoining the slot space.

This sealing system has two seal pairs in the notch space F between the sash frame beam 7 and the cheek frame beam 4, the seal pair is comprised of two

seals

29a, 30a or 29b, 30b, respectively, one of them seal in two seals is set up on the cheek frame beam 4 and another seal is set up on the sash frame beam 7, respectively. In each of the two separating web regions I and II or III and IV, the respective seal pair is provided with two

different seals

29a, 30a and 29b, 30b, respectively.

The two seal pairs are of identical design, but each have two

different seals

29a or 29b and 30a or 30 b. But the seal pairs themselves are each identically constructed. But its arrangement in the pocket space is different.

On the first seal element pair in the first or third insulating tab region I or III, the first seal element 29a (hereinafter referred to as the seal stop) is disposed on the sash frame beam 4 and the second seal element 30a (hereinafter referred to as the lip seal) is disposed on the sash frame beam 7. In contrast, on the second seal piece pair, the first seal piece 29b (i.e., the seal stopper) is provided on the fan frame beam 7, and the second seal piece 30b, which is referred to as a lip seal, is provided on the frame beam 4.

This is advantageous because, in order to form two sealing element pairs each having two different sealing elements, only two different sealing element configurations are still generally required, which simplifies the production and handling.

Each pair of sealing elements together forms a sealing chamber 34a, b therebetween which is closed almost all around with the web 59 of the sash or frame sill in the closed position of the wing. Furthermore, it is further advantageous to form a further sealing chamber 35 between the pair of seals. In this way, three sealed

chambers

34a, 35, 34b are constructed in the pocket space, adjacent to each other perpendicular to the (main) plane of the door or window.

With the seal right, four stop areas a1, a2, A3, a4 are formed in the pocket space, which block the otherwise gap formed in the closed state of the wing in the pocket space between the frame beam and the frame beam.

The two outer stop regions a1, a4 are formed between the metal profile of the frame beam 4 or the sash frame beam 7 and the corresponding one of the

sealing elements

30a, 30 b. While two further (intermediate) stop regions a2, A3 are formed directly between the two

seals

29a, 30a or 29b, 30b of each seal pair. The four stop regions a1-a4 ensure a significant reduction in heat conduction compared to known solutions.

This advantageously at least simply hinders the direct flow of air in the slot space F between the two spaces separating the door or window from each other in the closed state of the wing. Therefore, heat conduction in the pocket space can be minimized to a large extent. In addition, sound transmission is also reduced through the notch space F.

Fig. 4 shows the

first seal

29a or 29b of one of the seal pairs. This seal is also referred to as a seal stop in the following. The sealing stop has a base web 38, a retaining foot 36 preferably molded on the base web, and a stop web 37 extending obliquely at an angle of more than 60 °, in particular at an angle of 90 °, to the base web 38. Here, the base web 38 has two regions of different thickness on both sides of the stop web 37. The retaining feet 36 are formed in the respectively associated separating

webs

13a, 24a for the snap-locking engagement in the grooves 39 pointing into the slot space F.

Fig. 5 shows the

second seal

30a, 30b of the two seal pairs, which forms a lip seal. The

seals

30a, 30b, which are designed as lip seals, have a base section 40 and preferably two sealing

lips

41 and 42, which extend substantially perpendicularly thereto. The sealing lip 41 (which interacts with the stop web 37 of the respective other sealing

element

29a, 29b) forms part of the central sealing region 50, while the other sealing lip 42 is formed at its end as a stop sealing region 51 (here with a small cavity 52) oriented at right angles thereto.

Furthermore, the

seals

30a, 30b, which are designed as lip seals, have one or preferably one or (here) two or

more cavities

43, 44 in their base section 40. The cavity improves thermal insulation. The base section has a base web 45 which is designed with fastening means (preferably sealing feet 46 for locking into corresponding grooves 47 of the separating webs) for fastening to one of the separating webs. Two

side webs

48a, 48b extend at right angles to the base web 45 and merge at their ends into the sealing

lips

41, 42. Furthermore, the support web 48c extends between the ends of the

side webs

48a, 48b at an acute angle α relative to the base web 45. As a result, the side webs 48a or the sealing lip 41 in the extension are securely supported, preferably on the profile stop

webs

55, 56.

The stop sealing region 51 is connected (spaced apart) to the base section 40 by the connecting web 49. This simplifies assembly. The stop sealing region 51 has a fastening means with which it is locked to a mating profile stop tab of the sash frame rail 7 or of the cheek frame rail 4. Preferably, the fastening means is a foot 53 with which the stop sealing region is fastened in a groove 54 of the profile stop

webs

55, 56.

The stop sealing area 51 of one of the two sealing element pairs sealingly bridges the gap between the free end of the profile stop tab 55 of the sash frame beam 4 and the opposite corner of the sash frame beam 7, while the other stop sealing area sealingly closes the gap between the free end of the profile stop tab 56 of the sash frame beam 7 and the opposite corner of the sash frame beam 4.

The two

seals

29a, 30a or 29b, 30b of each seal pair together form an intermediate seal, respectively, approximately at the level of the separation tab region I, II or the separation tab region center of II, IV, respectively. Each of the two intermediate seals consists of one of the stop sealing lips 41 of the respective

second seal

30a, 30b (i.e. lip seal) and one of the stop tabs 37 of the respective

first seal

29a, 29b (i.e. stop seal). In each case a pair of seals is provided in the outer region of the slot space on the profile beam in order to seal one of the two stop sealing regions 51. Some additional advantageous details of the arrangement of the pair of seals, or here the pair of seals on the cheek frame beam 4 or the fan frame beam 7, will be seen next.

As can be seen in fig. 3, the base webs 38 of the stop seal are each preferably dimensioned such that they fit exactly into the undercut-free grooves 57 on the frame bars or frame bars in the installed state. The

seal members

29a, 29b are thus well and securely mounted to the frame beams of the cheek or sash frames, respectively.

The two respective fastening elements on the lip seal (here the retaining feet 46 and the feet 53 in the separating

webs

15a, 23a and the groove 47 and the feet 53 in the groove 54 of the profile stop webs 55, 56) interact with the bearing webs running obliquely between them to ensure a correspondingly good fit. The sealing

elements

30a, 30b are thus well and reliably mounted on the frame profile or the sash profile, respectively.

The

other frame rails

5, 6 and the fan frame rails 8, 9, 10 are preferably (but not necessarily) constructed the same as the frame rails 4 and the fan frame rails 7 shown in fig. 2 and 3, along with the sealing system with the sealing elements of fig. 4.
