Such sealing profiles are used for example in room and front doors and windows. Special application find this sealing profiles in the field of sound insulation, namely for soundproof doors, in which case always two sealing profiles are arranged side by side and with a small distance from each other.

Of the gaskets more than 6000 different configurations and shapes are known in the prior art alone for the above-mentioned door and window seals, the individual sealing profiles differ in their profile structure. For this purpose, on the one hand, the lip seals and on the other hand, the hollow chamber seals to call, which can be combined and scaled arbitrarily.

From the publication DE 20 2008 013 985 U1 a sealing arrangement for an openable element, such as a door or a window is known, wherein the sealing element in the gap between a frame and a wing member has two spaced apart sealing lips, which arrange with the wing element closed such that an air chamber is formed between them. As a result, a multi-chamber subdivision of the gap to be sealed at one point is possible, whereby the efficiency of such a seal is increased at this point.

Next is from the document DE 33 05 029 A1 a composite window sash with two separate individual seals can be removed, wherein the two individual seals are formed as a separate lip seals and seals one of the seals to the interior and seals the second seal to the outside. The seals are each provided in a corresponding groove in the window.

The publication DE 20 2004 005 464 U1 describes a sealing profile for use in a window or door, wherein the sealing profile is arranged in the folding area as a central seal and the seal has a plurality of individual chambers and seals the window to the window frame with a seal.

From the publication DE 35 24 124 A1 is an elastic sealing profile strip for sealing joints between the elements of a window or a door known, which is in the form of a simple lip seal, a combination of lip seal and hollow chamber seal or only in the form of a hollow chamber seal.

Furthermore, from the publication DE 299 00 650 U1 to remove a seal assembly for windows and doors, which has a sealing element and a counter-element, these elements are formed in two parts, whereby an efficient seal is realized in a simple sealed area.

Next are various strand-shaped sealing profiles, especially for windows, doors and the like, from the document DE 298 08 411 U1 known, which serve to seal a gap between the window sash and window frame. Here, a wide variety of configurations are shown, wherein these are designed as hollow chamber seals and are arranged with a correspondingly formed foot in a groove. Furthermore, a double hollow chamber profile seal is disclosed which, in a sealing area, very efficiently separates the gap between window frame and window element seals, with a total of use according to the use of three individual chambers are formed in the installed and closed state.

From the publication DE 82 06 824 U1 a door seal for sealing a joint of a door is known, wherein a main seal and a visual seal seal the gap between the door and the door frame.

From the publication DE 297 16 361 U1 is a seal for a building window is known in which a sealing profile serves to seal the closed wing, which serves the thermal separation, sound insulation and to improve the overall visual impression as well as protection against moisture and dirt.

The publication BE 827 106 A1 describes an elastic sealing profile with a cover lip, which can be provided in a door frame for one-sided sealing between the door frame and door leaf, in addition, a cover without sealing function is additionally provided.

The publication DE 200 16 444 U1 describes a seal assembly for sealing a closure member to a frame having a first sealant for a shock absorbing and partially sealing function and a second sealant for a main sealing function, wherein the main sealant is made operational only when the closure member has moved to the closed position.

From the publication DE 195 32 125 A1 is an insulation device consisting of an insulating web made of plastic and a center seal made of rubber, this is used for the thermal separation of light metal profiles in the window.

Multi-part sealing profiles for windows for the purposes of sound and heat protection are known in the art, but they have a single appropriately designed sealing head. For this exist as already mentioned at the beginning numerous variations, which sometimes more and less effectively meet the heat and the sound insulation.

The problem with the previously known in the prior art sealing profiles and their arrangement within the door are their weaknesses in terms of sound insulation on the one hand and their non-optimal thermal protection. Especially in this day and age, heat protection is of particular importance. In the renovation of residential buildings old window and door seals are often replaced with new sealing profiles of the same or similar type, which, however, no advantage in terms of sound insulation and heat protection is achieved. Approach is trying subsequently retrofitted more seals in the doors and windows to be rehabilitated, for which corresponding grooves are incorporated into existing frames, in which then a further additional seal is introduced.

Next, the aspect of sound insulation, especially in banks and the like. Buildings and organizations of particular importance, which is why there are always used today two separate sealing profiles in a door frame, for example, an office door, so as to ensure the requirements for discretion and the associated sound insulation to be able to. However, in addition to the material consumption, this entails a considerable installation effort, which means that the costs are disproportionately high.

The manufacturing costs of a new window or a door with a soundproofing seal include the incorporation of a first groove, the incorporation of a second groove and the respective installation of a corresponding sealing profile.

The present invention has for its object to provide an alternative door or Fensterfugenabdichtungsprofil, which makes it possible to meet the high demands on the heat protection and sound insulation and to improve each of these, this being done in a particularly simple manner and in particular the subsequent retrofitting of existing systems, such as built-in windows, doors should be possible without much time. In particular, for this purpose, the task is taken to realize a cost-effective to manufacture and at the same time easy and inexpensive to install door or Fensterfugenabdichtungsprofil, in particular, the assembly costs are to be kept low during subsequent installation.

This object is achieved with a sealing profile according to claim 1.

According to the invention, the sealing profile has a second sealing head arranged on the foot region for sealing a second joint section, the sealing of the joint sections by the respective sealing head being independent of the sealing of the other sealing head.

In this way, a sealing profile is formed, which is particularly suitable for applications in the field of increased sound and heat protection, to be installed in new as well as existing installations. In addition to existing standard windows and doors existing soundproof doors can be easily adapted in a repair of the sealing profile in the simplest way, in particular, the rapid assembly of a sealing profile is in the foreground. The necessary additional material consumption in contrast to a conventional sealing profile is only 20 to 50%, which cost represents a negligible contribution to the total cost of a seal with installation in a window or door. The installation costs outweigh and are reduced to half, since now no longer two seals but only a seal needs to be installed.

The greatest advantage is the combination of the two seals in a profile, the seals in two different areas, ie joint sections, the joint, which surrounds a window or a door circumferentially circulating, effect a seal, whereby the sound better reduced and held the heat is, as it would be possible in the prior art by means of only one seal in a profile.

The arrangement of the two seals in different joint sections of the at least almost circumferential joint (in a window, the joint is circumferential on all sides, in a door at least three sides), these different sections are particularly preferably arranged side by side, but their orientation is offset from each other, for example If the joint sections are arranged over the corner, a surprisingly high degree of protection for both sound and heat is formed, which efficiently reduces the transmission of sound and heat and thus meets current and future requirements for sound and heat protection ,

When using the sealing profile according to the invention, sealing takes place during closing by elastic deformation of the sealing heads against the retaining part.

Both new and to be renovated doors, windows and existing other types of arrangements with a holding part and a pivoting part arranged thereon can already be equipped according to the factory or cost with a sealing profile according to the invention be provided, the replacement only brings a small amount of work with it, which corresponds to the replacement of only one sealing profile.

The fact that the first sealing head and the second sealing head are arranged at an angle of 90 ° to each other, there is a very efficient design with respect to the sound and heat protection, as in this surprisingly simple way the construction of the transmission of sound or heat extremely is efficiently reduced, with only a sealing profile is used, which seals only in two separate joint sections of the joint accordingly.

In particular, the first sealing head and / or the second sealing head is connected to the foot region via a connecting section, so that the space between the two sealing regions increases and forms a quasi three-chamber system (in the embodiment with two hollow chamber seals and the intermediate chamber formed therein) , which reduces the transmission of sound and heat more efficiently.

In particular, the foot area on a Einbaufuß, whereby the sealing profile can be placed in the simplest way in a milled or prefabricated groove or on a sealing profile receiving a metal frame.

The one or more connecting portions may also be formed differently long, so that the two sealing regions can be arranged clearly separated from each other in their respective joint sections, so that the sound insulation is increased by the larger air gap between the two sealing portions. Nevertheless, the arrangement continues to be realized with only one foot area.

The first and the second sealing head are designed as a lip seal and / or hollow chamber seal. Here, the most varied embodiments of lip seals as well as hollow chamber seals can be used, but one simple trained hollow chamber seal within the meaning of this invention already delivers excellent results in terms of sound and heat protection.

Another particular advantage is that the material of the sealing heads and the foot area is different, wherein the material of the foot area has a greater hardness. In this way, the sealing profile can be very easily pressed into a groove provided, without the foot area is destroyed or damaged.

The material of the first and the second sealing head may be of similar design, wherein in particular the production can be carried out in a simple process, wherein the production could be carried out as a mono-extrusion.

Alternatively, the material of the first and the second sealing head may be formed differently, whereby it is possible to design, for example, an inner and an outer seal in different ways. For this purpose, for example, be formed in the form of an outer seal, one of the two sealing heads, which, for example, the special requirements to the outer environment by appropriate choice of materials account, so that it is UV-resistant and weather-resistant. Whereas the further sealing head could be made of a simple material, in particular made of a softer or foamed material, since this increases the efficiency in terms of sound and heat protection.

The material used for the sealing profile may be PVC, TPE, EPDM, PP and / or PU, wherein in a material mixture, the sealing profile is co-tri or more extruded. This makes it possible to design individual sections of the sealing profile with a very cheap material that meets the requirements for the appropriate area sufficient.

Other special design features are shown in the accompanying figures.

Hereinafter, embodiments of the invention will be described in detail with reference to the accompanying drawings. In this case, a known in the prior art sealing profile in a known installation situation is shown as a figure first and in the associated figure b and c is then the novel sealing profile according to the invention further explained.
