Window profile system especially for skylight structures

The invention relates to a window profile system, in particular for skylight structures, comprising a so-called horizontal and vertical profiles forming a lattice structure in the openings of which the glass or similar panels are mounted using glazing strips with glazing seals, from which the strips 10 associated with either the horizontal or vertical profiles are cut off at the intersections, the second strip continuing possibly past the intersection.

In a conventional window profile system such as that described above, the truncated lists at intersections are designed to be dimensioned as precisely as possible so that they joined the 15 pages as seamlessly as possible with respect to the intersecting lists. To ensure the watertightness of the seam, the seams are most often puttyed. In order to get the cut strip as close as possible to the strip intersecting with it, the glazing seal of the continuous continuous strip has to be cut at 20 intersections. In addition, the ends of the glazing seals of the strips coming to the intersection have to be shaped in order to achieve the most accurate compatibility possible, in which case the seals must also be very precisely dimensioned. Such a procedure is quite cumbersome and in practice often leads to unsatisfactory joints.

A window profile system is also known in the art, in which separate glazing seals, either T- or X-shaped, are used at the intersections to seal the intersection. This eliminates the requirement for an accurate dimensioning of the glazing beads, but the glazing seals must now be particularly carefully dimensioned so that they can be joined seamlessly, for example by gluing at the ends of the junction joint. Thus, in practice, the seal has to be assembled almost separately before the glazing beads are installed, which makes it substantially more difficult to assemble the skylight structure, for example.

It is therefore an object of the present invention to provide a window profile system which can avoid the a-installation difficulties associated with the above-mentioned known systems and, on the other hand, avoid the problems associated with their precise sizing. This is realized by a window profile system according to the invention, in which a trough-like sealing piece is fitted over the intersection of the horizontal and vertical profiles, parallel to the cut glazing strip, which covers the ends of the cut strip both on the top and on the 10 sides. Thus, time-consuming and cumbersome table setting is not required. The sealing piece prevents water from penetrating inside the roof and allows movements due to the temperature and load of the external glazing beads. In addition, unlike before, the sealing of the continuous glazing strip past the intersection point 15 does not have to be broken, but it can continue as a whole past the intersection point.

Preferably, the sealing body comprises a trough-like sealing strip and a plate-like seal arranged below it. The sealing strip comprises a substantially planar base surface 20 and associated side surfaces at an acute angle to its plane, the part of which is cut away along the length of the base surface to allow the glazing strip to pass through transversely to the sealing strip. In order to facilitate installation, it is advantageous to form the sealing strip and the associated seal as a unitary unit.

The invention will now be described in more detail with reference to the accompanying drawings, in which Figure 1 shows a connection of a window profile system according to the invention with sealing pieces, Figure 2 shows a top of the sealing piece, Figure 3 shows a cross-section of the sealing piece

Figure 1 is a top plan view of the so-called window profile system associated with the window profile system according to the invention. joint of horizontal and 3 71972 vertical profiles (not shown). Glasses 1 or other similar panels are installed in the openings of the lattice formed by these profiles. The glazing 1 is installed in place using glazing strips 2 to which rubber glazing seals 3 are attached to provide a tight connection.

These glazing seals are fitted in the cavities formed in the lower surface of the glazing strip 2 so as to protrude when installed outside the glazing strip, forming inclined side surfaces which prevent water from penetrating under the seal. The glazing strip 2 is fastened to the horizontal or vertical profile below, for example with screws through a plastic piece 9 acting as a heat failure. At the intersection of the glazing strips, one of the strips is cut off, as has been done before. However, the cutting does not now have to be as precise 15 as before, because the ends of the cut glazing strip are covered with a sealing piece 4. Thus, the exact dimensioning of the seals of the cut glazing strip is not as essential as before. In addition, the sealing piece 4 allows the thermal movement of the ends of the severed glazing bead without the risk of leakage-20. In addition, the glazing seal 3 of the continuous glazing strip 2 running continuously at the intersection can continue integrally past the intersection, which significantly simplifies the installation. In addition, if there is a need to continue the continuous continuous glazing strip, the plant site 25 can be easily protected under the sealing piece 4.

As shown in Fig. 1 and in more detail in Figs. 2 to 4, the sealing piece 4 comprises a gutter-like sealing strip 5 and a rubber sealing plate 6 mounted below it, the sealing piece 4 formed therein is fixed to the glazing strip with a seal 11 integral to the continuous glazing strip 2 or below the frame profile passing below the intersection. As already mentioned, the special purpose of the tii-35 sealing piece is to seal the ends of the cut glazing strip 2 by means of a seal 6. The sealing piece 4 71972 is furthermore shaped so as to direct, for example, the water flowing along the surface of the glass 1 away from the junction. The seal 6 is further shaped so as to pivot uniformly on the glazing seal 3 of the glazing strip 2 passing through the intersection.

Figures 2 and 3 show in more detail the shape of the sealing strip 5. It comprises a substantially planar bottom surface 7 and, at an acute angle to its plane, associated side surfaces 8, the central part of which is cut off by the Lei-10 to allow the passage of a glazing strip 2 running transversely to the sealing strip. The side surfaces of the sealing strip are cut obliquely at an angle oC to the longitudinal axis of the sealing strip. The angle oC is preferably 100 to 120 ° and most preferably about 110 °. Aluminum alloys as well as plastic are suitable for the materials 15 of the sealing strip 5.

Fig. 4 shows a rubber sealing plate 6 to be fitted under the sealing strip 5. Sections corresponding to the cuts of the side surfaces 8 of the sealing strip 5 have been made in the central area of the plate 6. However, the preferred cutting angle β ma β is about 60 ... 80 °, most preferably 70 ° with respect to the longitudinal axis of the plate 6, deviating from the cutting angle of the side surfaces of the sealing strip.

The invention has been described above on the basis of only one exemplary embodiment. Thus, it will be appreciated that quite extensive changes may be made thereto without departing from the scope of the appended claims.

Thus, the structure is also suitable for use in the so-called In connection with a T-joint, by cutting off the sealing piece, for example at the second sections of its side surfaces. Although the sealing strip 30 and its seal are shown above as separate pieces, it is possible that they are already connected to each other during manufacture to facilitate installation or are otherwise connected, especially when the sealing strip is made of a plastic material. In addition, the seal 6 35 does not necessarily have to be in the form of a plate covering the entire lower surface of the sealing strip 5, but can be adapted to surround only the edges of the sealing strip 5. In addition, the material of the seal 6 may be other than rubber.
