DE3415679A1 - Profiled strip for sealingly surrounding a window pane or a door element - Google Patents

Abstract

The profiled strip has in the strip body (11) a hollow chamber (12) running in the longitudinal direction. This chamber is connected by means of first ducts (13) to the bottom (10) of that groove (3) in which the window pane or the door element (4) is sealingly mounted. Second ducts (14) connect the hollow chamber (12) with that side (6) of the profiled strip which is exposed to atmospheric influences in the mounted state of the strip. In order to avoid spray water penetrating into the groove (3), but nevertheless to achieve good aeration and drainage, the second ducts (14) are arranged in an offset manner in the longitudinal direction of the hollow chamber (12) in relation to the first ducts (13). <IMAGE>

Description

Profile strip for sealing a

Window pane or a door element PROFILE BAR FOR SEALING A WINDOW GLASS OR DOOR ELEMENT The invention relates to a profile strip for sealing a window pane or a Door element, which comprises a solid body with a groove intended for it is to take up the edge of the window pane or the door element in a sealing manner on the end face.

Such sealing profile strips, which are usually made of vulcanized rubber exist have been known for a long time, as is the type, such as the window pane (which, for the sake of simplicity, will only be discussed in the following) can be easily inserted into this groove, which is also known as a glass rebate, but the side walls of the profile strip are still under pressure against the window pane invest. The CH-PS 423 179 serve as an example. The profile bar body can otherwise outside the area of the glass rebate, especially what the number, shape and length of the sealing lips are concerned, some of which lean against the pane, others against the frame to prevent rainwater from entering to prevent.

With many heat-insulating elements, for example also with insulating glass, the front sides of the disc are relatively cold, if on both sides, that is inside and outside, for example in winter there are different temperatures. Because at high indoor temperatures in buildings, the moisture content of the air also is higher than that of the outside air, there is a migration of moisture (Vapor diffusion) from the moister to the drier side. This gets moist Warm air in the area of the glass rebate, i.e. the groove, and can pass through the relatively cold Condense the face of the disc. This condensate can too Corrosion and cause other damage if it is not immediately derived or even better prevented will. So far, the simplest countermeasure known was the two legs the profile strip that form the glazing rebate to provide those with holes, which is exposed to the effects of the weather when the bar is installed. These holes, which served as steam expansion openings, but have the disadvantage that with extreme driving rain as a result of high wind speeds (in buildings or also in vehicles) individual rain splashes penetrate through these holes in the glass rebate and can cause similar damage such as condensation. This effect will even more so if the inner connection between seal and element is not one hundred percent is airtight. If there is back pressure in front of the building facade, air comes out of the glass rebate out, the same back pressure as the area as a result of the holes mentioned having in front of the building facade. If dynamic pressure and driving rain occur at the same time, it can happen that the same amount of air that gets into the room passes through the same amount of water is replaced as that on the facade via the steam relief holes expires. This can lead to the fact that the glass rebate is completely filled with water.

Attempts have been made to prevent water from entering these holes Part by doing this to prevent you getting angled tubes or downward pushed open caps from the outside into the holes and tried to to protect the area of the air inlet from driving rain. This measure affects but the visual impression and is therefore undesirable in most cases.

The object of the invention is therefore to provide a profile strip create where this disruptive effect does not occur and still driving rain or splash water cannot penetrate directly into the glass rebate.

Experience has shown that such a profile strip is characterized by the features of Claim 1 characterized.

In the accompanying drawings, 2 are preferred embodiments the profile strip according to the invention shown; further embodiments not shown result from the following description of these examples. They show: Fig. 1 shows a first embodiment without a recess groove in the bottom of the glass rebate, Fig. 2 shows a section along the line II-II in FIG. 1, and FIG. 3 shows a second embodiment with recess groove.

First of all, it should be noted that the external shape of the Profile strip for the present invention has no influence. The bar must only have a groove 3 delimited by 2 legs 1, 2, the so-called glass rebate. In this groove 3, as only indicated in Figure 1, the element 4, here a double glass pane, inserted so that its edge is encompassed by the two legs 1, 2, which against them under pressure. The element 4 lies here against individual, in Spacers arranged at a distance from one another and extending transversely to the groove 3 5, the so-called blocking. In this figure, 6 is the outside of the Profile strip denotes, d. H. the side that will look after the window pane is installed exposed to the weather on the outside of the facade or the vehicle is. The glass rebate 3 has a small groove 7 which is provided for reasons of elasticity has to be, but only a subordinate role for the present considerations plays. The lower legs 8, 9 shown in the figures are also of no concern; with them, the profile strip on the frame, not shown in detail anchored.

Because especially in winter the temperature differences on both sides of the element 4, here the glass pane, considerably could be and thus also the moisture content of the indoor air relative to the outdoor air, can in the Glass rebate 3 condense the air as a result of this temperature difference. The condensation initially collects in the small groove 7, but would later cover the entire base Cover 10 of the glass rebate 3. Even if both the profile strip and the element 4 mostly made of relatively moisture-insensitive material, this is resistance against corrosion not unlimited. A remedy must therefore be found to prevent the To drain the glazing rebate 3 and at the same time to equalize the pressure inside and outside.

As already mentioned, up to now you have drilled through the outer leg 2 two holes directly to the glazing rebate 3 and closed them on the outside Tubes angled at the bottom or with caps.

This closure was absolutely necessary because it turned out that especially splash water that was whipped against the outside 6 in a storm wind, get into the glass rebate and fill it up. These tubes or caps were clearly visible from the outside and therefore unattractive. So it had to go to another Solution to be sought.

According to the invention, this consists in that the glass rebate 3 having strip body 11, from which the legs 1, 2, 8 and 9 extend, a hollow chamber 12 extending in the longitudinal direction thereof is arranged. Your cross section can be anything, as a comparison of FIGS. 1 and 3 shows. This hollow chamber 12 is now through spaced apart first channels 13 with the floor 10 of the glass rebate 3 connected. This allows the water that has penetrated into the hollow chamber 12 expire. The hollow chamber 12 is now drained through second channels 14, which extend from it obliquely downwards to the outside 6. What is essential is that, as shown in Figure 2, these second channels 14 opposite the first channels 13 are arranged offset in the longitudinal direction of the hollow chamber 12. Penetrates rain or Splashing water in the second or outer channels 14, so arrives the water first of all into the hollow chamber 12 and is distributed there. Since each only single drops or splashes can penetrate, they are distributed in the in relation to the channels relatively large hollow chamber 12, so that above the There is always an air space free above the water level, which is connected to the glazing rebate base and ensures full pressure equalization. Because high pressure peaks that Could press water into the glass rebate base, provided that this is not on the inside of the room is one hundred percent sealed, only occur for a short time, the volume is sufficient the hollow chamber 12 in order to collect any water that may enter and after dismantling the pressure peak, generally after a maximum of a few minutes. Since with the help of the glass rebate 3, which is open to the outside, moist room air is drawn into this penetrates, is quickly discharged to the outside, there is a vapor pressure equalization.

In the figures, the profile strips are shown; like them on the underside of the element 4 can be used. On top of the element 4 the bars are upside down, which would mean that the second channels 14 would run diagonally upwards instead of downwards, and thus the rainwater could flow into the glass rebate 3 without further ado. On the vertical sides of the element 4, these second channels 14 would be inclined, but at least in horizontal planes run, which would be a bit better, but still unfavorable enough.

It must therefore be provided that the second channels 14 also in these Profile strips also run obliquely downwards. In general one can therefore say that regardless of the position in which the profile strips are, these second channels 14 must always proceed in the manner mentioned. This requires that the profile strips are designed differently, but only with regard to the channels 14. They can still be extruded in any length; only when the second channels 14 must be open the different usage consideration be taken.

It makes sense that especially with those profile strips that the upper edge of the element 4 closes off, the hollow chamber 12 no longer for drainage can serve. But it is not superfluous because it takes care of, along with the channels 13, 14, for the necessary ventilation or for vapor pressure equalization, because condensation phenomena can also form there.

The better the entire element 4 is ventilated all around, the less condensation can occur.

The profile strip according to Figure 3 differs from that according to Figure 1, apart from its external shape, which does not matter, especially through a special recess groove 15 on the bottom 10 of the glass rebate 3 and through the different arrangement of the hollow chamber 12 relative to the glass rebate 3. The recess groove 15, which of course can also be provided in the embodiment according to FIG. 1, collects the condensed water, and therefore it is ensured that the first channels 13 from Bottom 16 of this recess groove 15 go out to the profile strip at the bottom Edge of the element 4 to cause proper drainage.

In Figure 1, the hollow chamber 12 is as can be seen directly below the Glazing rebate 3 and arranged symmetrically to it; so it is symmetrical about a longitudinal center plane A-A perpendicular to the floor 10. So are those too first channels 13 symmetrical to this plane. In Figure 3, however, the hollow chamber 12 laterally offset to the glass rebate 3. They then also run correspondingly obliquely first channels 13, and they can therefore with sufficient diameter because of their inclined arrangement relative to the recess groove 15 this not only fully encompass, but even Reach adjacent areas of the glass rebate 3, so that the recess groove 15 comprises only part of the width of the channels 13, as can be seen from FIG is. This achieves particularly good drainage.
