Abstract

A window casement hollow section, in particular made of plastics, is provided on its outer side with a glass pane holding groove (G), followed at the inner side of the section by a middle zone (M) that consists of an inner and an outer profiled strip (12 and 11) and of an intermediate cavity (14) that contains a metallic reinforcement section (13). The hollow section further contains a joint clearance (F) whose width (f) is determined by the width (s) of a lateral rabbet (S) that delimits it on one side, less the width (d) of its sealing edge (D) that overlaps with the corresponding window frame. In order to improve such a window casement hollow section so that it may be narrower than state-of-the-art window frame casement sections of a similar type, while being as stable or even more stable than such window frame casement sections, the middle area (M) of the hollow section is at the most twice as wide as its joint clearance (F).

Description

The invention relates to a window frame hollow profile, especially made of plastic, the outside one for Edging of the glazing rebate serving for the window pane, then one at a time an outer and inner profile web and one in between lying, containing a metallic reinforcement profile Cavity existing middle area and inside a rebate air area has the width by the width of a him one-sided side flap minus the width its sealing edge overlapping the associated frame is determined.

Window casement hollow profiles of the above type are general known, for example according to DE-GM 9 319 617. Such Sash frame hollow profiles have despite their plastic nature sufficient stability and strength, not least because of that in the cavity of their central areas lying metallic reinforcement profile is given. Such reinforcement profiles consist of multiple angled sheet steel, often also in the form of a hollow profile, a comparatively wide cavity in the casement profile required. The well-known casement hollow profiles are therefore relatively wide, which is correspondingly smaller window glass surfaces conditional and also for the appearance of the window overall is disadvantageous. Therefore, these are known Sash frame hollow profiles, for example also for style windows not suitable.

The object of the invention is based on monument protection aspects a window sash hollow profile suitable for style windows to create that with sufficient or even improved stability, practically as narrow as Is wooden window profiles.

This task is based on a window sash hollow profile of the type mentioned in the introduction solved that the central region of the hollow profile at most twice as wide as its clearance area. Because of that comes one to a particularly narrow casement design, which too a significant improvement in such sash profiles provided window and especially his Appearance leads. Such narrow profiles are also for style windows good to use.

To a particularly narrow sash profile one comes when the cavity lying in the middle area almost as narrow as the inner and outer profile web is and accordingly in its wall thickness narrow reinforcement profile is largely filled. As a result, the central area of the casement profile can be extremely are kept narrow, namely only a few millimeters wider than the area of the clearance air, which with such Turn-tilt windows provided with hollow profiles is approximately 12 mm. At the same time it brings between the inner and outer Profile web arranged in close proximity to them Reinforcement profile a significant increase in stability.

Although from the magazine "Kunststoffe im Bau 17. Year 1982, Issue 3, pp. 158 to 163 a window sash hollow profile known, which is already kept very narrow.

The disadvantage of this, however, is that a further narrowing only with additional edging on the inserted Reinforcement profile is possible. Still, it would Hollow profile does not comply with the applicable monument protection aspects Style windows just because it is only in view width, but not perpendicular to the window plane to the current style window dimensions would be adaptable.

In the inner profile web of the central area is conventional an undercut receiving groove for fittings molded. According to a further feature of the invention this receiving groove has a simple T-profile, the cavity as well as the metallic, flat sheet metal held in it Reinforcement profile at both ends towards the rebate air area and the T-shaped receiving groove encompasses narrowly at a distance run angled. This can be sufficient Strength of the middle area made as narrow as possible because the groove is only profiled in a simple T-shape contributes to this.

Furthermore, the cavity and what is inside Reinforcement profile angled at both ends at different widths run, with the wider angled end extending up to can extend in the gusset flaps. The reinforcement profile advantageous at its shorter angled end 90 ° in the opposite direction to the slot additionally be angled.

The hollow profiles described above can easily also used to build a double casement window frame become. In this case, one of the opposite each other in the closed position of the window Hollow profiles on its inner profile web middle frame leg to be attached, which is a metallic Reinforcement profile and an outer stop bar has forming side fold flaps. The reinforcement profile can be used for this of the middle frame leg from a nail like a head profiled, double-layer angled sheet steel exist on which project beyond the casement profile Nail head one encompassing one with the latter, accordingly undercut receiving groove, the side fold flaps forming stop bar is pushed. To a you get a particularly narrow double wing frame joint according to the invention when on the middle frame leg opposite side of the air gap area to the two sash frames originally existing, towards each other all or part of the side flaps pointing away and on the remaining side fold flap stump of the sash frame not supporting the middle frame leg an inner one that still overlaps the other casement Stop bar as a correspondingly corrected new side fold flap is attached. This allows double-sash windows unusual in the middle wing joint area narrow, namely up to only 80 mm wide double frame dimensions can be achieved in the wing closed position.

a horizontal section through the central region of a double casement window, which is provided here with partially cut casement profiles of Figure 8.

The in Fig. 1 and 2 shown in vertical and horizontal section double casement window has a built-in frame, which consists of the horizontal upper and lower frame members 1,1 'and the two vertical frame members 1 ", 1 1 and in the upper part of the All consists window lying transverse spar 1 ^IV, the so-called Loos wood. consist of plastic profiles 2 with inserted therein, rectangular profiled metallic reinforcing hollow profile 3. between the Loos timber 1 ^IV and the upper cross member 1, such frame spars disposed inwardly in the direction 4 to open skylight wing 5 , while between the cross member 1 ^IV and the lower cross member 1 'two turn-tilt window sash 6,6' are arranged, which according to Figure 2 in their two closed positions with their inner casement hollow profiles 7 and that with one of the two hollow profiles 7 firmly connected, middle frame legs 8 close together in a window-sealing manner.

The window sash hollow profiles used in the windows described above 7 are of natural in Fig.3 Size reproduced texture. They exist made of extruded plastic and have an outside Edging of the window panes 9 serving glazing recess 10 and then a central region M inwards, that of an inner profile web 11, an outer profile web 12 and one in between, with a metallic Reinforcing profile 13 provided cavity 14. To the Middle area M closes further to the inside of the rebate air area F, that of the person sitting on the central area M. Side fold flaps S flanked with seal D embedded therein is. The broad dimensions of the central area M are with m, that of the rebate area F with f, that of the side fold flap S with s and that of the sealing edge D with d designated. This determines the width f of the Air gap area F to f = s-d. The width m of the central area 3, M is only a few millimeters larger than the width f of the air gap area F. This narrow design of the Middle range is achieved here by the fact that in it lying cavity 14 practically the same narrow as the inner one and outer profile web 11 or 12 and by the in its Wall thickness corresponding to narrow steel reinforcement profiles 13 is largely filled out.

In the inner profile web 11 is a simple one T-profile receiving groove 15 molded for receiving various fittings can serve. In the present The case is a corresponding one profiled push rod 16 with locking bolt sitting on it 17. These can be in the groove 18 of the fixed frame 1 embedded, not shown locking parts interact. The cavity 14 as well as the one located therein Reinforcing plate 13 run at both ends to the rebate air area F back and the T-shaped receiving groove narrowly spaced comprehensively angled, angled at different widths. The wider angled extends twice folded end 13 'into the side fold flap S, while the shorter angled end 13 "of the reinforcement sheet 13 receiving angled cavity end 14 'as Screw area is formed and on both sides Narrow extrusion clearances leaving screw rib 19 is partially filled out.

The casement hollow profile of the type described above differs more similar to conventional hollow sections Art, especially because of its extremely narrow central area M, whose width m is less than or equal to twice the clearance width f is, i.e. m≤2f. In the present case it is Extremely narrow middle area, namely only 15 mm in total wide. The small width of the simple also contributes to this T-shaped receiving groove 15 at. Despite his Narrow construction is the sash hollow section 7 of large Stability and especially torsional rigidity.

Advantageous examples of installation and use of the new Sash frame hollow profile are shown in Figures 4 to 6. So Figure 4 could be a vertical section through the top of a Represent sash frame, being in the receiving groove 15 of the inner profile web 11, a guide rail 20 is used is located in the above the push rod 21 Retaining pin 22 of a stay arm slidably guided is. The guide rail 20 is molded onto it Screw fastening strip 20 'on the inner profile web 11 fastened by means of several fastening screws 23.

In the case of Figure 5 is in the receiving groove 15 of the sash hollow profile 7 a corner guide rail 24 is used and likewise via a screw fastening strip attached to it 24 'and fastening screws 23 on the inner profile web 11 attached. The existing in the corner guide rail 24 Recess 24 "serves in its upper area for receiving a corner deflection belt, not shown.

Fig. 6 shows the natural representation in Fig.2 reproduced in the middle joint of the two Close position of the double window opposite vertical Frame spars 7 ', 7 ". Both frame spars are completely identical trained, but arranged in mirror image to each other. On the sash frame spar 7 'is here in the rebate air area still attached a middle frame leg 25, the in the present case also from a hollow plastic profile 26 and there is a metallic reinforcement profile inside 27 contains. This reinforcement profile 27 consists in present case from a substantially P-profile double-layer angled sheet steel, which with its widened Profile head 27 'of the blow bar 25' of the frame leg is facing. In this blow bar, which at the same time the side fold tab 25 "of the middle frame leg 25 forms, there is a dovetail-shaped undercut Receiving groove 28 into which the frame leg 25 covering trim 29 can be inserted.

7 are the metallic reinforcement profiles 13 at their shorter angled Ends 13 ‴ an additional 90 ° in to the associated one Recording groove 15 are angled in the opposite direction. As a result, greater stability can be achieved, and in particular also the screw fastening option for the middle frame leg 25 can be improved because of that Fastening screws 25 ‴ also in the angled Ends 13 ‴ of the steel reinforcement profiles 13 can be screwed in. That also increases stability here compared to Fig. 6 deeper angling of the profile head 27 'and its penetration through the Fixing screw 25 ‴.

One especially for the central vertical bars Double casement window is a suitable casement hollow profile shown in Fig.8. Its central area M is related to its folded air space F is as narrow as it used to be. The steel reinforcement profile 13a has none here protruding into the side fold flaps S of the casement hollow profile 7a double angled end. Rather own it here the inner profile web 11 containing the receiving groove 15; the cavity 14 that partially surrounds it and that in the latter included reinforcement profile 13a a substantially plate-like profile. Since the side fold flap S is metallic here is not reinforced, it can easily e.g. in the places 30 or 31 are separated, so that the in Fig.9 particularly narrow double profile design results. Here is on the left casement hollow profile 7a 'is also very much narrow reinforcement profile 32 screw-fastened, the here simply made of a double-layer profiled like a nail on the head there is angled steel sheet, on the over which Wing frame profile 7a 'protruding nail head 32' one the latter encompassing, undercut accordingly Recording groove 33 'provided stop bar 33 is pushed. On the diagonally opposite the middle frame leg 32 The side fold flap is the side of the rebate air area S partially according to section line 30 in FIG removed and on the remaining side fold flap S 'of the sash frame not supporting the middle frame leg 7a "a cross-over the other casement 7a ', inner stop bar 34 as a correspondingly corrected new side fold flaps attached. The one on the opposite Side fold flaps lying on the corner of the other casement 7a ' S is here at the interface shown in Fig.8 31 have been completely removed. Overall, it also results here the condition according to the invention that the width m of the Wing profile middle area M smaller than twice the Rebate width f is. This way it is extremely narrow Frame design in the wing joint area of a double casement window to achieve the added advantage of great strength and Has stability.

It is understood that within the scope of the present invention still some modifications are possible. So it could Sash frame hollow profile while maintaining its extremely narrow Construction instead of plastic in principle Light metal, e.g. Aluminum.
