The invention relates to a hollow profile with a profile body made of plastic, which is bounded by outer walls, wherein a part of the outer walls forms a Falzluftbereich for the stop of a further hollow chamber profile, wherein a Falzluftteilbereich the folding air area is provided for receiving closing elements and / or fitting elements and wherein the profile body has a profile body length, a window with a casement in which a glass element is mounted, wherein the casement is formed by hollow chamber profiles, a door with a door frame, which is formed by hollow chamber profiles and a window frame for a window or a door of hollow chamber profiles.

Plastic profiles for windows or doors are currently provided with a so-called Euronut, which extends over the entire length of the folding area, ie the area in which the sash frame strikes against the frame. This Euronut is intended to accommodate fittings or fitting elements. After this Euronut is open to the outside, these fittings are visible with the window open or with the door open, which suffers the visual appearance. In addition, it is associated with the fact that the hollow chamber profile must have a certain height to allow the formation of these Euronuts or is an increase in height at the expense of thermal insulation and the stability of the hollow chamber plastic profile. For example, describes the DE 103 10 958 Al a plastic frame profile for windows and / or doors, in particular window frame profile, with a plurality of chambers and with an aligned to a Falzluftbereich Falzluft wall area in which a reinforcing agent is used in a first chamber. The folded-air wall region has a receiving channel for receiving closure means with an opening air gap oriented in the longitudinal direction of the receiving channel, the ratio of the height of the receiving channel to the width of the receiving channel being between 1: 2 and 2: 1 N2007 / 10300 ·· ···· · · ···························································. The closing means are in the channel inserted or clipped executed. The closing means themselves are screwed to an underlying reinforcement for the profile or fixed via receiving channel legs in the form of a snap connection.

It is the object of the invention to provide an improved hollow chamber profile available.

This object of the invention is achieved in that the Falzluftteilbereich the hollow chamber profile over the profile body length is formed flat and groove-free and below the Falzluftteilbereich a - viewed in cross section - closed hollow chamber is arranged with a hollow chamber floor, and each independently by a window or a door or a frame, which have the hollow chamber profile according to the invention, wherein in the hollow chamber, a fitting or closing element is at least partially arranged. The advantage here is that the hollow chamber profile has a better profile stiffness and thus a lower tendency to buckling, even if the hollow chamber profile is not equipped with conventional, known from the prior art, stiffening elements. The hollow chamber profile is also easier to produce, since it has a homogeneous compared to known hollow chamber profiles, simpler cross-section. The incorporation of fitting or closing elements is also improved, wherein at least the majority of the same is not visibly absorbed by the possibility of integration of these fitting or closing elements in the hollow chamber under the Falzteilbereich and protected from weathering. By this design, a reduction in the height of the Falzluftbereiches is possible, whereby the thermal insulation value of the window or the door can be improved.

According to one embodiment of the invention, it is provided that the Falzluftteilbereich starting from a first vertical side wall of the profile body, at least approximately horizontally extending in the direction of a second vertical side wall of the profile body, so this Falzluftteilbereich is formed in the edge region of the hollow chamber profile in Falzluftbereich. It is thus the profile cross-section further simplified so that the manufacturability of this hollow chamber profile can also be further simplified. In addition, the positioning or installation of closing or fitting elements is simplified. N2007 / 10300 • · · · · ······ • · · · ··· · · ··· · t · I · ···· 3

The width of the hollow chamber - viewed in cross section - at least approximately correspond to a width of the Falzluftteilbereichs, whereby the variability can be increased with respect to a variety of hardware or closing elements, in particular the assembly is simplified, as well as a balance of existing tolerances in the Dimensions of the hollow chamber profiles can be better balanced.

Furthermore, the hollow chamber may have a length which corresponds at least approximately to the profile body length, whereby this hollow chamber profile also more universal with closing or. Fitting elements can be equipped, in particular the positional fixation over the length of the hollow chamber profile can be adjusted.

The hollow chamber floor can be formed by an inner web of the profile body, said inner web has a wall thickness, viewed in cross section, which is between 80% and 150% of the outer wall thickness of the profile body. This is not only an additional internal stiffening of the hollow chamber profile and consequently a better statics for receiving heavy or large glasses possible, but it can also the fitting elements or closing elements a better basis for their installation and a higher pull-out strength for screws Be provided, these inner webs in the finished window or in the finished door, especially if they are arranged in the frame profile, also contribute to the better load transfer of a stored casement or door leaf.

At least one web can be arranged protruding on the hollow chamber bottom and in the direction of the fold region, with the aid of which a simpler tolerance compensation of distortions of the hollow chamber profile can be effected by the production by milling of the web, in particular a level compensation for the arrangement of the fitting or closure elements, which are installed resting on this dock, done.

Finally, it is advantageous if the hollow chamber is at least partially filled with foam, wherein the foaming can be present before the installation of the closing or fitting elements and in this case must be partially removed for the installation of these elements or foaming with a foam also Subsequently, after the installation of the closing or fitting elements takes place, making this a better stop in the N2007 / 10300

This hollow chamber profile 1 has a profile body 4 which is bounded by outer walls 5 and which has inner webs 7 in its interior for forming a plurality of hollow chambers 6.

At a mutually facing end portions of the sash frame profile 2 and the frame profile 3 a Falzluftbereich 8 is provided on the profiles, said two Falzluftbereiche 8 of the sash profile 2 and the frame profile 3 face each other and overlap each other in the closed state of the window or the door.

The hollow chamber profile 1 is made of plastic, as is known from the prior art, for example a thermoset or thermoset, such. PE, PVC or even of mixed materials, such. WPC (wood plastic composite), for example a mixture of wood fibers with PP. The hollow chamber profile 1 is preferably produced by extrusion, but can also be produced by other methods, for example extrusion or injection molding, etc.

According to the invention, a rebate air section 12 is now provided in Falzluftbereich 8 of the respective hollow chamber profile 1, which is executed flat and groove-free, wherein under this Falzluftteilbereich 12 each have a hollow chamber 13 is arranged. This hollow chamber 13 is closed when viewed in cross-section ausgefuhrt and is bounded by outer walls 5 and one or more inner web (s) 7.

The Falzluftteilbereich 12 preferably extends from a first vertical lateral outer wall 5 in the direction of a second vertical outer wall 5, so for example from the right side wall 5 in the direction of the left side wall 5 of the frame profile 3 and from the left side wall 5 in the direction of the right Side wall 5 of the sash profile 2Fig. 1.

The hollow chamber 13 is, as will be explained in more detail below, for receiving fitting elements or closure elements, as are customary in the window or door industry, provided. Preferably, the Hohlkammem 13 have a width, which - viewed in cross section - at least approximately corresponds to a width of the Falzluftteilbereiches 8 in this direction. In the context of the invention, however, this width may also be smaller or larger than the width of the folded-air-part region 12.

It is further preferred that the Hohlkammem 13 have a length which corresponds at least approximately to the length of the profile body 4, so these Hohlkammem 13 extend continuously through the hollow chamber profile 1. On the other hand, it is possible that discrete Hohlkammem 13 are provided, which are separated from each other, for example by vertical transverse webs.

Furthermore, in the context of the invention in the hollow chamber 13 webs 14 may be arranged, in particular be integrally connected to the profile body 4, as shown in Fig.l for the hollow chamber 13 of the sash profile 2. These webs 14 may be arranged on an inner, the hollow chamber 13 facing surface of an outer wall 5 or it is possible that, for example, if these webs 14 are arranged in the frame profile 3 of FIG. 1 that they are on a hollow chamber floor 15 in the direction are arranged facing the Falzluftteilbereich 12. On the one hand, these webs 14 can be used to receive at least parts of closing or fitting elements and thus to enable or support a positional fixation, and for this purpose these webs can be used. N2007 / 10300 # ..1 ··· · · · · · · ··

• · · ··· ···· ·· 7 14 with L-shaped cross section. On the other hand, it is possible that these webs 14, e.g. mushroom-shaped or with a square or rectangular cross-section (viewed in the end view), in which case these webs 14 can also serve to dimensional inaccuracies arising from the manufacturing process, for the planar arrangement of the closing or fitting elements in the To support or improve hollow chamber 13 by Beffäsungen or material removal in general of the webs 14. It can thus be simplified so the assembly. As can be seen further from FIG. 1, it is also possible for such webs 14 to be arranged on the other inner surface of an outer wall 5, which forms the folded air part region 12, in which case the webs 14 are also used as so-called screw lugs can and in each case two webs are arranged side by side lying at a distance, so that they are squeezed when screwing screws and thus the maintenance of screws of the fitting elements, ie the pull-out strength can be improved.

Since the hollow chambers 13 are closed to the outside by the outer walls 5 (viewed in cross section, the end faces are open, and are only closed by the welding of several hollow chamber profiles 1 into a frame), they become suitable for the installation of the fitting or closing elements opened, for example, milled. It proves to be advantageous if these Hohlkammem 13 extend over the entire length of the profile body 4, since thus the placement of the respective closing or fitting elements at any point in Falzluftteilbereich 12, of course, taking into account the particular circumstances, can take place, so that no attention has to be paid to a screening, etc.

Furthermore, it is possible that the position of the fitting groove can be kept variable due to the small depth of the hollow chamber profile 1 and the fitting groove, whereby the load can be better dissipated by the glass element.

By avoiding separate fitting grooves, as have hitherto been customary in the prior art, it is also possible to form the profile cross-section of the hollow-chamber profile 1 more homogeneously or to simplify it.

These fitting elements or closing elements, which are at least partially taken up by the hollow chambers 13, can be, for example, corner bearings or locking bolts, etc. N2007 / 10300 • ·· ·· ·· · ···· ·· ·· • -8th-

As can be further seen from Fig. 1, the dimensions of the hollow chamber profiles 1, i. the sash profile 2 and the frame profile 3, be sized so that an upper end of the frame profile 3 ends at least approximately at the same level as an upper end of the sash profile 2, respectively in the installed state of the profiles. By this raised shape of the frame profile 3, a greater coverage of the Glasfalzbereiches 11 is achieved, thus improving the thermal insulation of the finished window or the door insofar as a broad coverage of a spacer between the glass panes of a multi-pane glass is thus possible. Since these spacers are usually made of metal, they have a high heat conduction and can be reduced with this design of the hollow chamber profiles 1, the heat loss through this heat conduction through better insulation. In addition, but also the appearance of the finished window or the finished door is improved because no gradations between the casement 2 and the frame profile 3 are present in the outside or inside view.

In Fig. 2 shows a variant of the combination of sash profile 2 and frame profile 3 of FIG. 1 is shown. In this case, in particular, the frame profile 3, which has fewer inner webs 7 than that of FIG. 1, wherein here again, the hollow chamber 13 is formed analogously to that of FIG. 1 for receiving fitting elements and closing elements. By reducing the number of inner webs 7 creates a large-volume hollow chamber 6. Thus not only the profile cross-section is simpler and more homogeneous, so that it can be produced more cheaply, but is also the introduction of a thermal insulation, e.g. a foam insulation in this hollow chamber 6 easier.

FIG. 3 shows a detail in the corner area of a window 16 with a built-in closing element 17.

It can be seen very clearly from FIG. 3 that the folded-air-part region 12 has a planar surface and is groove-free. Only in the region of the closing element 17, the underlying hollow chamber 13 is opened, so that the closing element 17 at least partially, or completely, to be able to arrange it. As can be seen very clearly from FIG. 2, in the opened-air condition of the window 16, only an approximately plate-shaped element of the closing element 17 is visible, which protrudes slightly beyond the surface of the seam. N2007 / 10300 ··· »Φ ΦΦΦ · 4 · ·· Φ φ ·· «• ♦ ♦ < -9-luflteilbereiches 12 of the hollow chamber profile 1, i. the corresponding outer wall 5, projects. This closing element 17 is screwed to the outer wall 5, as already stated above. However, other types of connection are possible, e.g. Gluing, etc.

It should be mentioned at this point that it is within the scope of the invention, of course, possible to arrange in a hollow chamber 13 a plurality of closing elements 17 and fitting elements, in particular it is also possible that a plurality of closing elements 17 may be operatively connected, so that e.g. be actuated by the movement of a window handle or door handle several of these closing elements 17.

In order to avoid a large-area opening of the hollow chamber 13 in the case of the arrangement of an effective connection with greater length, there is the possibility within the scope of the invention that the connecting element is already introduced into the respective hollow chamber profile 1 before the welding of several hollow chamber profiles 1 to the finished window frame or sash becomes.

Furthermore, it should be noted that it is of course also possible in the context of the invention - although not shown - that so-called stiffening elements, i. Stiffening profiles are arranged within at least one of the hollow chambers of the hollow chamber profile 1.

Fig. 4 shows another embodiment of a combination of the sash profile 2 cut with a frame profile 3 in end view, in this embodiment variant in the Hohlkammem 13 both hollow chamber profiles 1 each have a closing element 17 is arranged, for example, in turn, the closing element 17 and a shown in Fig. 3 another closing element 17 for the engagement bolt 18 in this. In this embodiment variant of the window 16, the glass element is designed as a three-pane glass with two Abstandhaltem. As can be seen from FIG. 4, the glass element does not strike a seal in the upper end region of the frame profile 3, as is the case with the embodiment variants according to FIGS. 1 and 2, but the stop between the frame profile 3 and the wing frame profile 2 takes place here This allows the glass surface to be completely visible from the inside. It is also in the variant of FIG. 4 - as in the preceding embodiments N2007 / 10300 ΦΦ ♦ t · # ··· • • • • • • • • • • • • * * * * * * * ft • • • · Φ ································································································································································· Lowering the glass in the glass folding area 11, and thus improving the thermal insulation of the window 16 accordingly

Furthermore, it should also be represented by this variant, that the cross sections of the hollow chamber profiles 1 may well differ from those of FIG. 1 or 2, ie a different arrangement or number of Hohlkammem 6 and a different arrangement and number of inner webs 7 in the frame the invention is possible.

In addition, this embodiment also shows that the cross sections of the hollow chamber 13 in the end view can also be made different, e.g. can be performed with rounding of the corner areas.

Furthermore, in this embodiment, an inner web 19 of the sash profile 2 is made thick-walled, in particular with a dimension of the wall thickness - viewed in cross section - which corresponds to between 80% and 150% of the outer wall thickness of the profile body 3. At least, however, this wall thickness of the thick-walled inner web 19 is 1.5 mm. It is thus achieved a higher stability for receiving the closing element 17 in the hollow chamber 13.

At least one thick-walled inner web 19 may also be formed in the frame profile 3, as indicated by dashed lines in Fig. 4. This thick-walled inner web 19 can form the bottom of the hollow chamber 13 of the frame profile 3 and thus serve for better support of the closing element 17 or a fitting element in the hollow chamber 13.

A subsequent to this inner web 19 vertical inner web, which limits the hollow chamber 13, may - as indicated in Fig. 4 by dashed lines - be made thick-walled, said inner web may be continuously extending to the underlying outer wall 5 of the hollow chamber profile 1.

In general, it should be noted that other inner webs 7 may be formed as thick-walled inner webs 19 in order to improve the statics of the hollow chamber profile 1 and to simplify the cross section, for example by reducing the number of Hohlkammem 6.

The hollow chamber 13 of the sash profile 2 is in this embodiment in three parts - viewed in cross-section - formed with a centrally larger hollow chamber 13 and laterally later each smaller Hohlkammem 13, these two smaller in cross-section Hohlkammem for receiving the screws of the closing element 17 are used. So essentially this embodiment corresponds to a variant with so-called screw lugs, these screw lugs are extended and form webs within the hollow chamber 13.

FIG. 4 shows the closed position of the window 16.

Although a combination of two hollow chamber profiles 1 is shown in each of FIGS. 1, 2 and 4, it is also possible to use only one hollow chamber profile 1 according to the invention for a window or a door, for example exclusively for the sash frame or exclusively for the frame.

Finally, FIGS. 5 and 6 show a variant of the window 16 in which two closing elements 20 are arranged in the frame profile 3, with FIG. 6 showing a detailed detail from the lower frame profile 3 according to FIG. 5. On the one hand, it should thus be clarified that the closing elements 17, 20 can also be arranged flush with the outer surface of the folded-air-part region 12, that is to say they can be received essentially at least almost entirely by the hollow chamber 13, and, secondly, this is also a closing element 20 can be seen, which can be used for example for a lock, in which case in particular a in Fig. 6 apparent, in plan view approximately T-shaped recess 21 should be noted, in which engages a bolt. Generally, however, the shape of the recess 21 is adapted to the corresponding shape of the lock, so it must not necessarily be T-shaped. For locking in this case, a bolt may be approximately mushroom-shaped, ie with a cross-sectional widening at its end, wherein the closing element 20 may be undercut on an outer cover in order to allow the engagement and locking of the bolt.

It is further possible that the hollow chamber 13 is at least partially filled with foam, e.g. with a PU foam in order to improve the thermal insulation or to improve the connection of the fitting or closing element 17 via adhesive connection. N2007 / 10300 • 1 I * · * ♦
