Abstract

A profiled seal made of elastic material for window profiles may be used in an advantageous manner, in particular at the weather side, if the sealing elements (12, 13) associated to the top side of the base body (10) of the profiled seal are provided with a decorative coating (33) made of a UV-resistant, non-cellular material. This decorative coating (33) makes it possible to give to the profiled seal a special appearance or a special design, and in addition allows very flexible materials to be used, in particular when the sealing elements (12, 13) are made of different materials, since the latter can be covered by the decorative coating (33).

Description

Sealing profile with coated sealing bead

Description

The invention relates to a sealing profile made of elastic material for sealing the window panes from the window profiles made of plastic or metal, in particular on the weather side with a profile base body, a molded anchoring wedge and molded sealing elements on the top of the profile base body.

Such sealing profiles are used in window construction in order to give the window panes the necessary fit and the effective sealing instead of the costly silicone or putty seals. Thermal insulation is of additional importance today, especially for window profiles made of metal. The sealing profiles made of elastic material are known for example from EP-B-0 247 533. Here, the seal attached to the weather side consists of a basic profile body made of corresponding harder plastic, the anchoring wedge formed on the profile side and the sealing area consisting of two sealing elements on the upper side of the basic profile body, that is to say on the side facing the window pane. An optimal sealing is ensured by the arrangement of two sealing elements one behind the other, whereby a special design of the outer sealing element also enables continuous laying in the corner area. However, these sealing elements and therefore also the entire sealing profile mostly consist of a gray or even black material, so that they are always clear, in particular from the inside of the window, and can also be seen as a nuisance in terms of appearance. In order to give them the necessary elasticity, however, it is necessary to use carbon black or the like as filler material, which in turn results in the corresponding coloring. If other materials were used, the permanent elasticity required for long-term use would not be guaranteed can be achieved and therefore not the possibility to continuously introduce this material in the corner area. On the other hand, such profiles, even if they consist of material of different hardness with respect to the sealing elements, must reliably prevent penetration both into the intermediate area between the window pane and the profile and also between the sealing elements. For this reason, only a certain material can be used, for example with closed pores, or with the same material throughout. However, this easily causes problems, particularly in the corner area, so that once again the older technology must be used, in which profiles which are vulcanized or vulcanized on are used in the corner areas. However, these vulcanization points or glue points bring with them uncertainty, so that if possible, continuous profiles are used.

The invention is therefore based on the object of designing a sealing bead in such a way that simple and safe installation with optimum optical and functional adaptation to the frame is possible.

The object is achieved according to the invention in that the sealing elements are provided in whole or in part with a decorative coating which consists of a non-cellular material and is UV-resistant.

This special design of the sealing profile first of all enables the elastic material to be processed advantageously to be reused, without adversely affecting its properties. This means that it is still possible, if the sealing profile is designed accordingly, to lay it continuously in the corner area and in other problem areas. In addition, such a decorative coating is also inexpensive because there is only a small material requirement and because it also gives the possibility, based on the usual sealing profile, of using sealing profiles that are precisely adapted to the application, without the entire sealing profile having a corresponding coloring or a must have an appropriate appearance. Coating is essentially for decorative reasons, but at the same time the effectiveness of the sealing profiles must be guaranteed. Since it is a non-cellular material, it is impossible for moisture to penetrate through the decorative coating and that this coating may also become detached. UV resistance guarantees a long service life without any change, so that a sealing profile designed in this way is ideally suited for problematic applications, particularly on the weather side.

According to an expedient embodiment of the invention, it is provided that the decorative coating is formed from a thin-film vulcanized plastic film. Such a film can be processed particularly well and at the same time in such a way that it completely and reliably covers the surface in the intended area. The application process ensures that a permanent connection between the decorative coating and the actual sealing element is achieved. The plastic film or the decorative coating can be applied so that it completely surrounds the sealing elements or the corresponding parts of the profile body. This makes it possible to use open-pore or otherwise designed materials for the sealing elements, which in turn have particularly favorable processing properties. As a result, the processing in problem areas such as in the corners and at T-joints u. much easier. Since the decorative coating consists of a non-cellular material, moisture cannot penetrate and there is therefore no fear of influencing the interior material. The decorative coating thus fulfills a double function, since it is used not only for visual reasons, but also to secure the sealing element material.

The design in which the decorative coating is arranged to cover the surfaces of the sealing elements visible through the window pane is to be regarded as a certain minimum requirement, since this ensures that all visible areas are given the color or design which they are intended to have. For example, it is possible to use a sealing profile with a white-coated window profile that exactly matches the color or that produces a certain effect that can only be achieved by appropriate coloring. A further embodiment of the invention provides that the plastic film forming the decorative coating is colored and / or transparent. This special requirement makes it possible to produce different effects if this is desired for the visual impression. For the covering and securing effect, on the other hand, it is sufficient if a thin-skinned decorative coating is used in a non-cellular structure. A transparent design can also have a special optical effect, in particular when an open-pore material is used for the sealing elements or one of the sealing elements.

The invention can be implemented particularly well if the sealing elements are formed by a sealing lip made of harder and a large-volume sealing bead made of softer, foamy material, wherein they represent a V-shaped expansion with respect to the center line of the anchoring wedge associated with the profile base body, and at least the free surfaces of the sealing bead are covered or covered by the decorative coating. This training is particularly suitable because the decorative coating is fully retained even in the case of the deformation resulting from the special design of the sealing lip and sealing bead and thus maintains the overall impression given by the sealing element. Regardless of how far the sealing lip and sealing bead move away from one another or deform one another, an identical or, in particular, optically identical surface is always guaranteed, and thus the desired optimal overall impression. Here, as already mentioned, open-pore foam can also be used for the large-volume sealing bead through the cover by the decorative coating, so that machining is also possible in the corner areas without a different impression being caused by the deformation of the particularly softer part of the sealing element can. In particular, however, the laying technology in the corners and other problem areas is in no way hindered by the decorative coating.

While the use of harder and less hard material for sealing lip and sealing bead is known from EP-B-0 247 533, the invention provides that the large-volume sealing bead consists of a 30 ^° or less Shore foam and with the profile body and the Sealing lip connected and is covered by the decorative coating. Ultimately, the decorative coating gives the option of using even softer material than, for example, foam rubber, in order to make laying in corner areas and other problem areas even easier. This sealing bead, which is made of very soft foam, is ideally suited to deforming, allowing it to be pressed into the problem areas and yet sealing effectively, the spring action caused by the foam or the sealing bead having a very advantageous effect on the sealing action of the sealing lip. It is also advantageous that, for example, better thermal insulation can be achieved by the higher proportion of air in the foam, so that better thermal insulation can be achieved especially in the area of metal and especially aluminum windows. The thermal insulation can be specifically improved by appropriate material or else the sealing lip or the profile base body also covering the profiles in the invisible area in order to improve the thermal insulation effect in this way.

In order not to hinder or possibly even favor the processing of the sealing elements and in particular the sealing bead, it is advantageous if the decorative coating has a similar, preferably the same Shore hardness as the sealing elements, preferably the sealing bead. Due to the vulcanization, an intimate connection between the two elements is ensured without the risk that the effect of the sealing elements will be worse.

The spring action mentioned earlier, which provides the sealing bead for the sealing lip, can be favored in accordance with the invention in that the sealing bead, with its much softer material, is designed to reach the foot of the sealing lip and the foot area of the anchoring wedge. Thus, when the window pane is placed or pressed onto the sealing elements, the sealing lip is displaced, its movement being cushioned by the foot which is supported on the sealing bead. At the same time, the foot deforms the sealing bead, so that this in turn advantageously lies evenly against the window pane and effectively seals the entire area. In the case of aluminum windows in particular, thermal insulation can be improved by a specially designed sealing profile. This is particularly the case when the basic profile body is equipped with an extension which extends below the sealing lip and extends far beyond, the decorative coating also partially or completely covering the extension. As a result, the metal surface of the frame can be covered to a greater or lesser extent, so that additional heat insulation is achieved here due to the special nature and the material of the sealing profile. The decorative coating leads to an additional seal, in particular when it is drawn into the end area of the attachment. The decorative coating can help to better fill existing or remaining gaps, or to ensure a uniform effect on the adjacent surfaces over the entire surface, because the same material is specified over the entire surface. Here again, it is not the coloring that is of particular importance, but rather the material used for the decorative coating, which in particular has a non-cellular structure.

The sealing profiles described in detail are primarily intended for use in the area of plastic and metal windows. They can also be used in the area of wooden windows with a corresponding adjustment and this is particularly the case if the anchoring wedge is made in two parts, with one wedge part at the front at the free end of the profile base body carrying the sealing bead and the other wedge part at the opposite end of the profile base body as in one A wedge that can be inserted in the wooden frame is molded on or is assigned to the entire contact surface of the profile base body in the form of an adhesive layer, the entire visible surface, at least that of the sealing bead, preferably having a decorative coating in the wooden handle. A sealing profile designed in this way can advantageously replace the expensive silicone or other plastics, with actually only one additional groove in the wooden profile having to be provided in order to effectively connect the two-part anchoring wedge in the end region to the wooden frame. If this is not the case or if it is a retrofit, the adhesive layer is particularly advantageous as a replacement for this second wedge part and makes it possible to use such a sealing profile effectively in this processing area as well. It is conceivable also that both a groove is provided in the wooden window and the fixation described on the adhesive layer. The sealing bead and possibly also the sealing lip are covered by the decorative coating, which expediently has, for example, the same grain, color or the like of the wooden frame, in order to enable adaptation. It is, of course, also conceivable to use a decorative coating which specifies a different handle in order to influence the overall effect of such a window in an optically advantageous manner. Here too, the decorative coating is of particular importance with regard to the visual and at the same time also the effect of securing the material. The latter in particular if the decorative coating largely covers or envelops the sealing elements, so that the weather conditions cannot influence them.

The invention is characterized in particular by the fact that a sealing profile is created that can be installed easily and safely, that has a high level of functionality, in particular in the problem areas of the corner and the T-connections, and that at the same time also visually adapts the sealing profile to any circumstances enables without having to keep huge amounts of special type sealing profile. Rather, the sealing profile of whatever design is provided with the decorative coating in the critical, in particular the visible areas, which, as described, has an optical and at the same time functional effect. The functional effect also makes it possible to use materials that increase the insulating effect, which can be protected from the weather by the protection provided by the decorative coating and protected in the long term. Overall, the sealing profile according to the invention is distinguished in that the same basic profile is available for all areas of application, that special additional processing, ie. H. just requires the application of the decorative coating. The manufacturing costs are thus only marginally influenced, but at the same time the functionality of the sealing profiles is significantly increased.

Further details and advantages of the subject matter of the invention result from the following description of the accompanying drawing, in which preferred exemplary embodiments are shown with the necessary details and individual parts. Show it:

1 shows a sealing profile with a V-shaped basic design and an extended basic profile body,

Fig. 2 shows a sealing profile for normal use, for example

Plastic windows,

Fig. 3 is a sealing profile in section for use on wooden windows and

Fig. 4 shows another embodiment of a sealing profile with sealing bead and sealing lip made of different materials.

The sealing profile shown in FIG. 1 is a special version insofar as it is essentially intended for aluminum windows. Regardless of this special field of application, a corresponding sealing profile 1 secures the slot between window pane 2 and frame 3, details not being shown here.

The sealing profile 1 consists of the basic profile body 4, the anchoring wedge 6 molded onto the underside 5 and the sealing elements 8, 9 assigned to the upper side 7. The thread 10 only has stability functions and facilitates the assembly of such a sealing profile.

The sealing element 9 is provided with a support wedge 11, which rests on the window pane 2, so that the entire sealing profile 1 can be supported on the frame 3 or the aluminum frame part 12.

The sealing profile shown in FIG. 1 has an extended extension 13 in order to insulate the aluminum frame part 12 as inexpensively as possible. Here too, details have not been presented.

The sealing profile 1 is on the side assigned to the window pane 2 a decorative coating 15 covered. In the embodiment shown in FIG. 1, this decorative coating goes around the sealing bead 16 made of softer material up to the sealing lip 17 even up to the shoulder 13. This decorative coating 15 is of optical importance, since the entire side facing the viewer is so can get certain and uniform appearance, for example, adapted to the frame 3 used. At the same time, however, it is also possible to use a softer material here, for example the sealing bead 16, by means of the corresponding encapsulation or encasing, which does not necessarily have to be resistant as such to weathering conditions. It gets the necessary durability from the decorative coating 15, which is not cellular and is also UV-resistant.

1, FIG. 2 and also FIG. 3, the softer material is brought close to the foot 22 of the sealing lip 17. The designation of the interface at 18 clearly shows that this course can also be selected so that the effect of the foot 22 and on the other hand of the anchoring wedge 6 can be guaranteed or influenced. In the embodiment shown in FIG. 2, the foot 22 is effectively cushioned when the sealing lip 17 is pressed down, the anchoring wedge 6 at the same time being very stable because the foot region 23 is sufficiently predetermined here.

Both in Fig. 1 and Figs. 2 and 3 sealing bead and sealing lip are formed so that they allow and specify a V-like spread to the center line 20 of the anchoring wedge 6.

With 19 the incision is designated, which is to specify the parting area when laying in the corner area, which facilitates laying in these problem areas. The same applies in principle to T-joints u. a. Realms

Fig. 3 shows a special embodiment in that such a sealing profile 1 is provided for use on wooden frames. For this reason, a different design of the anchoring wedge 6 has been used, which is in two parts. In the embodiment shown in FIG. 3, a stepped wedge part 25 is provided on the side of the profile base body 4 assigned to the sealing bead 16, while the rest of the contact surface 29 of the profile base body 4 is provided with an adhesive layer 30. This adhesive layer 30 acts as a second part of the wedge or anchoring wedge, a second wedge can also be provided at the end region of the profile base body 4 if the wooden windows or frames also have a correspondingly adapted groove or if these can be introduced into the frame . Ultimately, however, the same advantageous effect can be achieved via the adhesive layer 30. Here this second wedge part is provided with the reference symbol 28 in order to clarify that such a key protruding downwards and to be pressed into a groove may be here! can be arranged.

In the embodiment according to FIG. 3, the visible outer surface is also covered by the sealing bead 16, wherein the decorative coating 15 can also be carried out down to the cavity 26 via the cover strip 27 if this is expedient for visual reasons.

In the embodiment according to FIG. 4, the sealing lip 17 and the sealing bead 16 are clearly separated from one another, the sealing lip 17 being subjected to a corresponding load by the one not shown here. Window pane 2 moved in the direction of the sealing bead 16 The sealing bead 16 as a whole is quasi molded onto the professional body 4 and cannot influence or cushion the movement of the sealing lip 17 or any other part. In the embodiment according to FIG. 4, the entire surface of the sealing bead 16 and also the sealing lip 17 is covered by a decorative layer 15. The decorative layer 15 is also drawn around the sealing lip 17, around the area that is also visible when the sealing lip 17 is moved or bent away to cover the decorative coating 15

All of the above-mentioned features, including those that can be seen in the drawings alone, are regarded as essential to the invention alone and in combination.
