Description

The present invention relates to a window with a casement window cover, a window frame and step glazing, the casement window being formed of plastic profiles for casement window binding and having an outside and an inside facing the inside of the room, the step glazing having a protrusion located on the outside and between the stepped glazing and the casement window cover, a cavity of a fold of window glass is formed.

Technical field

Typically, plastic windows and doors are welded from plastic profiles cut into a mustache and then glazed, the glazing being held between the outer glass stop and the inner rail for securing the glass. As a material for plastic windows, hard polyvinyl chloride (PVC) is almost exclusively used in practice, although its stiffness is relatively high in comparison with other plastics, but it is relatively low in comparison with metals. Therefore, flaps with a width or height of more than 80 cm have to be stiffened with reinforcing profiles inserted in hollow chambers, made mostly of steel.

State of the art

In the field of so-called Structural Glazings, it is known that glazing, in particular permanent glazing, is glued to a frame of steel or aluminum. Already there are proposals (DE 4112826 A1, DE 29824119 U1, EP 1070824 A2, DE 19802663 C2, DE 3543524 A1) on the use of plastic windows with glued glazing, in which high rigidity of the glazing is also partially used to give sufficient rigidity to casement window frames without additional steel reinforcing elements.

From EP 1067268 A2, a window system with a window glass and a continuous casting profile is known, in which, instead of the usual multi-sheet glazing unit, two separate window panes are connected directly through a special cast profile with the formation of a casement window cover without a glass fold. Such a window system is technologically very laborious to manufacture.

The solutions proposed so far were unsatisfactory, since the door structures have too little bending and torsional rigidity, the structures themselves are very complex or the installation of window glass is excessively laborious.

Object of the invention

Therefore, the present invention is based on the task of creating a plastic window with a casement window cover with glued glazing, in which these disadvantages are eliminated. Other tasks arise from the advantages of the proposed technical solutions in comparison with previously known solutions.

SUMMARY OF THE INVENTION

The invention solves this problem using a window with a casement window cover, a window frame and step glazing according to claim 1, preferably in combination with one or more features of the dependent claims, respectively, using a profile for casement window cover for such a window according to claim 7 or 8 claims.

An essential feature of the solution of the problem according to the invention is the central functional chamber in the profile for casement window binding having several hollow chambers. This central functional camera, in turn, can be divided into several sub-chambers to increase rigidity, however, its rigidity is increased without the use of plug-in amplification profiles. Instead, the necessary rigidity is provided by gluing the outer wall of the central functional chamber with the inner side of the outer window glass of the stepped glazing.

According to a preferred embodiment of the invention, the gluing is carried out by silicone glue, wherein the glue line has a width of from about 5 to 10 mm, preferably from 6 to 9 mm.

The gluing of stepped glazing with casement window binding is preferably performed around the entire perimeter, i.e. on all four sides, including the corner sections of the window pane. According to an alternative embodiment of the invention, gluing can be performed at intervals at regular intervals, in particular after gluing, for example 10 cm in length, a segment, for example 2 cm long, not containing glue, and the like can be provided. Or, the sizing can be in the form of a continuous tape on three sides, while several tears can be provided on the lower horizontal side to allow the cavity formed by the fold of the window glass to be ventilated through these tears.

The central functional chamber on the side facing the inside of the room preferably adjoins the window device socket, so that the wall of the central functional camera facing the room side simultaneously forms the outer wall of the window device socket. In this way, particularly thin and at the same time torsional and bending stiff geometry profiles can be created. In casement windows, the nest for window devices is used to fasten window devices in it, and its geometry is practically fixed.

The upper wall of the central functional chamber, i.e. the wall facing the cavity formed by the fold of the window glass, according to the invention, is directly adjacent to the cavity formed by the fold of the window glass. This makes it possible to direct to the maximum extent the forces from the glazing directly into the central functional chamber. Finally, the lower wall of the central functional chamber is adjacent to the cavity formed by the fold, passing between the casement window cover and the window frame.

According to a preferred embodiment of the invention, the profiles for casement window binding, when viewed in cross section of the lower horizontal profile, have above the nests for window devices or above the central functional chamber an abutment surface parallel to the glazing plane provided with a double-layer adhesive tape. This double-layer adhesive tape is primarily used to facilitate the installation of glazing, as well as to fix the glazing in the casement window cover until it is completely cured or glue vulcanized.

For the manufacture of the sash, profiles for the casement of the window binding are first cut into a whisker and welded to each other by a method known to the person skilled in the art, the weld beads in the corner zones being preferably removed. In the finished welded and peeled casement window frame set in the center - small window glass forward - stepped glazing, and casement window cover can be fixed in a standing or lying position. After the inner surface of the inner (i.e., smaller) window glass is pressed against the two-layer adhesive tape, the glazing is first fixed in the casement window cover. Then, a seam with a width of approximately 5 to 10 mm between the inner surface of the outer window pane and the bonding surface of the central functional chamber is filled with a suitable adhesive, in particular silicone adhesive. The adhesive is then cured, for example, by a curing reaction. Alternatively, before inserting the glazing, it is also possible to apply, in particular around the entire perimeter, an adhesive roller on the outer bonding surface of the central functional chamber, which, after installing the glazing in the frame, will connect the glazing and the casement window frame tightly or with a power short circuit.

According to a preferred embodiment of the invention, the profile for casement window binding has, along with the central functional camera and its adjacent socket for window devices, a thrust chamber for window glass, which is integral with the profile for casement window binding and, if necessary, can be divided into two or more cameras.

The thus-formed thrust chamber for window glass preferably has a flexible seal on the upper edge facing the glass that is formed thereon during extrusion and is intended to seal the gap between the inner thrust chamber and the glazing. This prevents the penetration of moisture into the gap between the thrust chamber for window glass and the inner surface of the stepped glazing, which provides almost complete protection of the double-layer adhesive tape.

According to another preferred embodiment of the invention, the central functional chamber of the lower horizontal profile for the casement window binding has one or more drilled or profiled holes that create a through connection between the fold-formed cavity passing between the casement window cover and the window frame, on the one hand, and a cavity formed by a fold of window glass, on the other hand, for ventilation of a cavity formed by a fold of window glass.

The concept proposed in the invention with a central functional camera, on the one hand, and a socket for window devices adjacent to it on the room side, on the other hand, makes it possible to execute profiles for the casement window cover according to the invention with an optically extremely small width with high stability and stiffness on bending and torsion. The invention, in particular, is suitable for PVC windows, however it can also be used for the manufacture of windows from polypropylene profiles or fiberglass.

Brief Description of the Drawings

Below the invention is described in more detail on the example of its implementation with reference to the accompanying drawings, which show:

Figure 1 is a cross section of a window according to the invention with stepped glazing;

Figure 2 is a cross section of a sash according to the prior art;

Figure 3 is a cross-sectional profile for the casement window binding according to the invention.

BEST MODE FOR CARRYING OUT THE INVENTION

Figure 1 shows the cross section of the window according to the invention from the casement window binding 1, window frame 2 and stepwise glazing 3. Window box 2 corresponds to the prior art and is composed in the usual way of frame profiles provided for such a window frame. The rigidity of the Central hollow chamber 25 is provided by steel reinforcing elements 26.

In itself, the known stepped glazing 3 has an outer window glass 10 and an inner window glass 9, the outer window glass 10 being larger than the inner glass by the size of the protrusion 8 of the outer glass.

Profile 6 for casement window binding in figure 1 is shown in the drawing clearly in cross section, and figure 3 is presented separately. It essentially consists of a central functional chamber 14, a socket 13 for window devices, a stop chamber 22 for window glass, and a stopper 27. The stop chamber 22 for window glass is divided by a jumper 23 into two smaller chambers.

Profiles for the window frame and for casement window frames are made of solid PVC.

The central functional chamber 14 has a wall 16 on the outside 4 that extends parallel to the glazing plane and serves as a gluing surface 17 to which it adheres to the stepped glazing. From the cavity formed by the fold of the window glass, the central functional chamber 14 is separated by a wall 18, which at the same time serves for fastening the known pads 12 used for glazing.

From the side 5 of the room, the central functional chamber 14 is bounded by a wall 15, which at the same time is the outer wall of the socket 13 for window devices. Thus, the socket 13 for window devices and the central functional chamber 14 are located practically on the same plane, which leads to an optically very narrow width of the casement window binding 1 according to the invention. Figure 2 for comparison shows a standard casement window binding at the same magnification.

Finally, from the formed by the fold of the cavity 20, located between the casement window binding 1 and the window frame 2, the Central functional chamber 14 is separated by the bottom wall 19, and the wall 19 has an outer side edge 28 for swelling drops.

Above the jack 13 for window devices there is a thrust chamber 22 for window glass, which in the above example is divided by a jumper in order to provide additional rigidity 23. From the outside 4, the thrust chamber 22 for window glass is bounded by an easily springy wall 24, which is provided with double-sided adhesive on the outside tape 29.

For mounting the windows according to the invention, a window box 2 and a casement window 1 are first manufactured in a known manner from the corresponding profiles 7 for the window box and profiles 6 for the casement window by welding them in a beveled area. After the casement window cover has been peeled, a double-layer adhesive tape 29 is applied to the outside of the wall 24 of the window chamber retaining chamber 22. Then, step glazing 3 is installed in casement window cover 1, centering it using glazing pads 12, two for each two adjacent sides of the sash. Briefly pressing the step glazing 3 to the free surface of the double-layer adhesive tape 29, the step glazing 3 is fixed. Then, the gap between the protrusion 8 of the window glass and the surface 17 to be glued to the wall 16 of the central functional chamber 14 is self-curing silicone adhesive. The protruding sections of the sizing place 21 can be painted over, and the sizing place 21 can be smoothed out in a known manner on its lower side facing the cavity 20 formed by the rebate. After the adhesive has cured in the sizing zone 21, the stiffness both in relation to bending and in relation to torsion is provided almost exclusively by step glazing 3. Moreover, the double-layer adhesive tape 29 serves almost exclusively for fixing purposes during installation, and to connect the step glazing 3 to the casement window with binding 1, it plays only a minor role.

The gap between the wall 24 of the thrust chamber 22 for the window glass facing the window glass and the inner window glass 9 is sealed in the upper region by means of a sealing tongue 32.
