Description

This invention relates to a sealing system for a door, window or facade element for a seam fold according to the preamble of claim 1.

Doors, windows and facade elements of the above kind have long been known. An important structural feature of such doors, windows and facade elements are profile beams (as a rule, cut at an angle), from which an external frame and / or sash frame are mounted. As a rule, profile beams are cut to a predetermined length from composite profiles. Then, from the beams of the outer frame or the beams of the sash frame, a thermally insulated system of profiles is created for door and window structures having a sealing system in the seam between the outer external frame and the sash frame.

To this end, in accordance with the prior art (and in accordance with this invention), the composite profiles of the beams of the outer frames and / or the sash frames consist of at least one metal outer profile, in addition, preferably of a metal central profile and a metal inner profile, which are connected with each other using at least one insulating zone that reduces heat transfer and consisting, for example, of one or more plastic insulating walls.

Typically, the gap in the seam between the outer outer frame and the sash frame (or corresponding beams) is sealed with a central seal (central seal system). For example, volumetric central seals with hollow chambers of coextruded material are known. In another common type of seal, called the thrust seal system, two relatively small seals are used on the outer surfaces of the profiles. It is necessary to further improve thermal insulation in these solutions and / or to reduce heat transfer.

In light of the foregoing, the objective of the invention is to create a door, window or facade element with a sealing system in the seam space, which provides particularly good thermal insulation between spaces separated from each other by the door or window, including in the seam space.

In the invention, this problem is solved due to the features of paragraph 1 of the claims. In accordance with this paragraph, the sealing system has at least one or (and this is particularly preferred) two pairs of seals, which in each case consist of a first seal on the outer frame and a seal on the sash frame, which together form at least one central seal , hermetically overlapping seam in the closed state of the sash. In addition, each of these two seals is separately fixed to the profile by means of a tongue and groove joint. Preferably, two pairs of seals are fixed to the beams of the outer frame and / or the sash frame in the grooves of the insulating walls.

In addition, as an additional preferred feature, at least one of these two seals has a thrust seal region. Preferably, in this region of the thrust seal, there is a fastening means, for example a tongue and groove connection on the wall of the sash frame beam (or the outer frame beam).

In general, through the use of one or two pairs of seals, a sealing system is obtained, which can be called a combined system consisting of a single or double central seal system and a thrust seal. This system provides very high tightness and excellent thermal insulation.

Most preferably, the system of composite profiles is made in the form of a system with three shells, consisting of two insulating zones with a double arrangement of pairs of seals. As the preferred material for the manufacture of these seals, EPDM (a copolymer of ethylene, propylene and diene) or TPE (thermoplastic elastomer) or a similar plastic (having different Shore hardness) are used - foamed or non-foamed, with or without hollow chambers. Universal seals are also possible, in which case combinations of materials (foamed or non-foamed) are made in the usual way or by co-extrusion.

All metal profiles are preferably made in the form of an extruded aluminum profile. Alternatively, it is possible to manufacture from another material, for example, from steel, or another method of manufacture is possible.

All insulating walls are preferably made of plastic material, for example, polyamide (PA66, PA6, PPA), polyester (PET, PBT), polyolefin (PP) or polyvinyl chloride (PVC), so that in each case a high degree of thermal insulation between adjacent metal profiles.

All insulating walls may have (but not necessarily) at least one hollow chamber. In each case, in the plane of the insulating walls, they can be combined by means of transverse walls into a kind of insulating wall of a higher order.

The insulating walls of the zones of the insulating walls can preferably in each case lie in the same plane. This solution is preferred (but not required), as it provides an ordered design.

According to a preferred embodiment, the sealing leg of one, all or several seals of the pair of seals is inserted into the groove of the seal of the insulating walls. This is preferable since, therefore, no protrusion of the insulating walls into the seam space occurs. However, in a less preferred embodiment of the invention, in the seals in each case there may be grooves in which protruding pins of the insulating walls can enter.

At least one seal of each pair of seals has one or more hollow chambers, thereby further improving thermal insulation.

Further preferred embodiments of the invention are disclosed in the dependent claims.

In addition, the invention provides a pair of door, window or facade element seals according to any one of paragraphs. 1-33 of the claims.

Examples of the invention are shown in the drawings and are described in more detail below. The drawings show the following.

FIG. 1: a door consisting of a sash frame and an external frame.

FIG. 2: sectional view of the sash frame profile and the outer frame in the closed state of the sash.

FIG. 3: an enlarged fragment of the seam in the arrangement according to FIG. 2.

FIG. 4: a first seal of a pair of seals according to FIG. 2 and 3.

FIG. 5: the second seal of the pair of seals according to FIG. 2 and 3.

In FIG. 1, a door 1 is shown having a pivoting and / or rotating sash with a sash frame 2 and an external frame 3 to which the sash is pivotally connected using one or more fittings. As an alternative to doors, this invention can also be used for windows or facade elements, etc.

The outer frame 3 of this door 1 has beams 4, 5, 6 of the outer frame. The sash frame 2 on the handle side has a vertical beam 7 of the sash frame, and on the hinge side, another vertical beam 8 of the sash frame. In addition, the sash frame 2 has an upper horizontal beam 9 of the sash frame and a lower horizontal beam 10 of the sash frame. Each beam 6, 7, 8 — in this case, using corner connectors (not shown here) —is connected to the casement frame 2, so that a panel can be installed in the casement frame 2, for example, glazing (not shown here).

In FIG. 2 shows a sectional view of the beam 4 of the outer frame and the beam 5 of the door leaf frame 1. Between the beam 4 of the external frame and the beam 5 of the leaf frame, a fold space F is formed in the form of a gap. This gap must be tightly closed.

The beam 4 of the outer frame has a first metal profile 11 (first outer profile), which is connected to the metal central profile 12 using at least one or more of the first insulating walls 13a, 13b (in this case oriented in parallel). These insulating walls 13a, b between the first metal outer profile and the metal Central profile 12 form in the beam 10 of the outer frame the first zone I (first plane) of the insulating walls. The second metal profile 14 — another outer profile — is also connected to the metal central profile 12 by at least one or more second insulating walls 15a, b (in this case parallel). The insulating walls 15a, b between the second metal profile 14 and the central profile 12 form a second zone II (second plane) of the insulating walls in the beam 10 of the outer frame. In the metal profiles of the beam 4 of the outer frame there are hollow chambers, which is preferred from the point of view of thermal insulation.

In FIG. 2, as an example, both zones I, II of the insulating walls on the beam of the outer frame have such insulating walls 13a, b; 15a, b, the corresponding end parts of which are connected with a geometric and power circuit with a connected groove of metal profiles.

Other beams 5, 6 of the outer frame are preferably made in the same way as the described beam 4 of the outer frame.

The sash frame beam 7 has a first metal profile 17 in the form of an external profile. In this case, at least one hollow chamber 18 is formed in the first metal profile 17. In addition, in the beam 7 there is a second metal outer profile 19, in which at least one hollow chamber 20 is also preferably formed. Between these two metal profiles 17, 19, a third metal profile is located - a central profile 21, in which at least one hollow chamber 22 is also formed. Alternatively, these metal profiles 17, 19, 21 can be made without hollow chambers or in each case have several mated cameras. Hollow chambers, depending on the circumstances, reduce heat transfer between the spaces adjacent to the door, window or facade element, and make it easy to install corner connectors, etc.

The first metal profile 17, in turn, is connected to at least one of the first or several first insulating walls 23a, b (parallel oriented in this case) with the metal central profile 21. These insulating walls 23a, b are between the first metal outer profile 17 and metal central profile 21 form in the beam 7 of the sash frame the first zone III (or plane) of the insulating walls. The second metal outer profile 19 is also connected to the metal central profile 21 by at least one or more second insulating walls 24a, b (in this case parallel). The insulating walls 24a, b between the second metal outer profile 19 and the metal central profile 21 form in the beam 7 of the sash frame a second zone IV (or plane) of the insulating walls.

In FIG. 2, zone III of the insulating walls of the profile beam 7 of the sash frame has insulating walls 23a, b, the end parts 25 of which are connected with a geometric and power circuit with a groove 26 of the adjacent metal profile (external or central profile), so that in each case, in particular, also in the direction of the z axis (cf. the coordinate system in the drawing) or in the direction perpendicular to the cross-sectional plane of the composite profile 4, a shear-resistant connection occurs between the insulating walls and the adjacent metal profile. Below this connection is also called shear-resistant connection. It provides resistance to shear against forces arising from the expansion of a window, door, etc.

In FIG. 2 shows that the insulating walls 24a, b of the second zone IV of the insulating walls of the sash frame beams 7 form between the second metal outer profile and the metal central profile 21 a separation zone between the insulating walls and the second outer profile 19, in which the non-shear sliding guide provides relative movement. Alternatively, a separation zone can also be formed between the insulating walls 23a, b and another metal profile, or between the outer profile and the central profile 21. For this, the insulating walls 24a, b in the direction of the y and x axis (relative to the coordinate system in Fig. 2) are connected when help kedernogo connection 27 with a geometric closure with a second metal outer profile. Thus, a sliding guide is formed. The shear resistance in the sliding guide perpendicular to the cross-sectional plane of the composite profile can, but should not, tend to zero. In common parlance, such a sliding guide is called a non-shear joint.

The location of the non-shear joint (in this case, in the plane IV of the insulating walls) should be understood as given as an example. Alternatively, the non-shear joint can also be located in the plane III of the insulating walls or in both planes III, IV of the insulating walls, or in another way. In addition, non-shear joint can be abandoned if the problem of expansion compensation is solved in another way or not solved at all.

In addition, the sash frame profile has a retaining bar 28, with which a panel, for example, glazing, is held.

The planes I, II of the insulating walls of the profile of the outer frame and the planes III, IV of the insulating walls of the profile of the sash frame correspond to each other.

Furthermore, in the gap or seam F between the outer frame beam and the sash frame beam, a preferred sealing system is installed to seal the gap in the seam F.

In FIG. 3 shows an enlarged view of the folded space F and adjacent insulating zones of the composite profile system according to FIG. 2.

The sealing system in the seam space F between the beam 7 of the sash frame and the beam 4 of the outer frame has two pairs of seals. Each pair of seals consists of two seals 29a, 30a or 29b, 30b, in each case one of the two seals is located on the beam 4 of the outer frame, and the other seal on the beam 7 of the sash frame. In each of the two insulating zones I and II or III and IV lies one of the pairs of seals having two different seals 29a, 30a and 29b, 30b.

Both pairs of seals are identical, but in each case have two different seals 29a or 29b and 30a or 30b. Thus, although the seals themselves are made in the same way, they are located differently in the seam space.

In the first pair of seals in the first or third insulating zone I, III, the first seal 29a, hereinafter referred to as the sealing stop, is located on the beam 4 of the outer frame, and the second seal 30a, below called the lip seal, is located on the beam 7 of the sash frame. In contrast, in the second pair of seals, the first seal (seal stop 29b) is located on the sash frame beam 7, and the second seal (lip seal 30b) is located on the outer frame beam 4.

This is preferable since for the formation of two pairs of seals, in each case having different seals, in general seals of only two different designs are required, which simplifies the manufacture of seals and their use.

In the closed state of the sash, each pair of seals together with the wall 59 of the beam of the sash frame or the outer frame forms between its seals a sealing chamber 34a, b, closed on almost all sides. Furthermore, an additional sealing chamber 35 is preferably formed between the pairs of seals. Thus, three sealing chambers 34a, 35, 34b are formed in the seam space, which are adjacent to each other in a direction perpendicular to the (main) plane of the door or window.

By means of pairs of seals, four thrust areas A1, A2, A3, A4 are formed in the seam space, breaking the gap that would otherwise have formed between the beam of the outer frame and the beam of the sash frame in the closed state of the sash.

Two external thrust regions A1, A4 are formed between the metal profile of the beam 4 of the outer frame or beam 7 of the sash frame and in each case one of the seals 30a, 30b. In contrast, the additional two (central) thrust regions A2, A3 are formed directly between the two seals 29a, 30a or 29b, 30b of each pair of seals. Compared with the known solutions, these four thrust areas A1-A4 provide a significant reduction in heat transfer.

Thus, in the closed state of the sash in the folded space F between two spaces separated from each other by a door or window, the direct flow of air is prevented at least four times. Thus, it is possible to significantly minimize heat transfer in the seam space. In addition, the sound transmission through the folded space F. is reduced.

In FIG. 4 shows a first seal 29 a, b of one pair of seals. Below this seal is also called the seal stop. The sealing stop has a main wall 38, preferably a holding leg 36 formed on it, and a stop wall 37 extending at an angle of more than 60 °, in particular at an angle of 90 ° to the main wall 35. In this case, the main wall 38 has two regions of different thicknesses located on both sides of the abutment wall 37. The holding leg 36 is made for engagement in the groove 39 of the corresponding insulating wall 13a, 24a, oriented towards the seam fold F.

FIG. 5 shows a second seal 30a, b of both pairs of seals forming an lip seal. The seal 30a, b, made in the form of an lip seal, has a main part 40 and preferably two sealing lips 41, 42 extending substantially perpendicular to the main part 40. The sealing lip 41 (in cooperation with the abutment wall 37 of the other seal 29a, b) forms a part region 50 of the central seal, while the other sealing lip 42 at its end is formed as a region 51 of the thrust seal (in this case, with a small hollow chamber 52), oriented at right angles.

In addition, the seal 30a, b, made in the form of an edge seal, has one or preferably in its main part 40 one or (in this case) two or more hollow chambers 43, 44. These hollow chambers improve thermal insulation. The main part has a main wall 45 made with fixing means (preferably with a sealing leg 46 for engaging in an appropriate groove 47 of the insulating wall) for mounting on one of the insulating walls 22, 23. Two side walls 48a, 48b extend perpendicular to the main wall 45 extending at their ends to the sealing lips 41, 42. In addition, between the ends of the side walls 48a, 48b, an abutment wall 48c extends at an acute angle α to the main wall 45. Due to this, the side wall 48a or (in extension) the sealing lip 41 is reliably supported, namely, preferably on the abutment wall 55, 56 of the profile.

The area 51 of the thrust seal is connected through a section 49 of the connecting wall with the main wall 40 (so that there is some distance between them). This makes installation easy. In this case, the thrust seal region 51 preferably has fixing means by which it is connected to the corresponding thrust wall of the profile — either the beam 7 of the sash frame or the beam 4 of the external frame. Preferably, the fastening means is a leg 53, with which it is fixed in the groove 54 of the abutment wall 55, 56 of the profile.

The region 51 of the thrust seal of one of the two pairs of seals hermetically covers the gap between the free end of the thrust wall 55 of the beam profile 4 of the outer frame and the opposite angle of the beam 7 of the sash frame, while the other region of the thrust seal hermetically closes the gap between the free end of the thrust wall 56 of the beam profile 7 sash frames and the opposite corner of the beam 4 of the outer frame.

In each case, approximately at the midpoint of the insulating zones I, II or II, IV, the two seals 29a, 30a or 29b, 30b of each pair of seals together form a central seal. Each of these two central seals consists of one of the stop sealing lips 41 of the corresponding second seal 30a, b (lip seal) and one of the stop walls 37 of the corresponding first seal 29a, b (stop seal). In the outer region of the seam space, one of the two thrust seal areas 51 for each pair of seals is sealed on the profile beams. Finally, several additional preferred details of the location of the pair of seals should be considered, in this case a pair of seals on the beam 4, 7 of the outer frame or the sash frame.

As can be seen in FIG. 3, the main wall 38 of the preferably thrust seal is designed so that, when mounted, it is precisely fitted to the non-undercut groove 57, 58 of the profile of the outer frame or sash frame. Thus, the seal 29a, b sits securely and efficiently on the profile of the outer frame or sash frame.

The corresponding effective fit on the lip seal is provided by two holding means, in this case, the fixing legs 46, 53, as well as the grooves 47 in the insulating wall 15a, 23a, and the legs 53 in the grooves 54 of the abutment wall 55, 56 of the profile, in cooperation with passing between them at an angle to the support wall. Thus, the seal 30a, b also reliably and effectively sits on the profile of the outer frame or the sash frame.

Other beams 5, 6 or 8, 9, 10 of the outer frame and, respectively, of the sash frame are preferably, but not necessarily, made as described using FIG. 2 and 3 of the beams 4, 7 of the outer frame and the sash frame together with the sealing system with seals according to FIG. four.
