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

Window frame hollow profile and double window frame made from it

The invention relates to a hollow window frame profile, in particular made of plastic, which on the outside has a glazing rebate recess which serves for edging the window pane, and in each case continuously thereafter inwards consists of an outer and inner profile web and an intermediate cavity containing a metallic reinforcement profile Central region and inside has a rebate air region, the width of which is determined by the width of a side fold flap delimiting it on one side minus the width of its sealing edge overlapping the associated frame.

Window sash hollow profiles of the above type are generally known, for example according to DE-GM 9 319 617. Despite their plastic nature, such sash frame hollow profiles have sufficient stability and strength, not least due to the fact that they are in the cavity of their Mittelbe - Rich lying metallic reinforcement profile is given. Such reinforcement profiles consist regularly of multi-angled sheet steel, often also in the form of a hollow profile, which requires a comparatively wide cavity in the sash profile. The known sash frame hollow profiles are therefore relatively wide, which means correspondingly smaller windows. Stersterglasflächen conditional and is also disadvantageous for the overall appearance of the window. Therefore, these previously known casement hollow profiles are unsuitable for style windows, for example.

The invention has for its object to improve a window sash hollow profile of the type mentioned in such a way that it can be kept narrower than the previous sash profiles of a comparable type with sufficient or even improved stability.

Starting from a window sash hollow profile of the type mentioned at the outset, this object is achieved according to the invention in that the central region of the hollow profile is at most twice as wide as its rebate air region. This results in a particularly narrow sash design, which leads to a substantial improvement in the window provided with such sash profiles and in particular also in its appearance. Such narrow profiles can also be used well for style windows.

A particularly narrow sash profile configuration is obtained when the cavity located in the central area is almost as narrow as the inner and outer profile web and is largely filled by the reinforcement profile, which is narrow in terms of its wall thickness. As a result, the middle region of the casement profile can be kept extremely narrow, namely only a few millimeters wider than the rebate air region, which is about 12 mm in the case of turn-tilt windows provided with such hollow profiles. At the same time, the reinforcement profile arranged between the inner and outer profile web and lying in close proximity to them brings a substantial increase in stability.

An undercut receiving groove for fitting parts is conventionally formed in the inner profile web of the central region. 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-like the reinforcement profile is held at both ends towards the rebate air area and the T-shaped receiving groove is angled and spaced narrowly around. As a result, the central region can be made as narrow as possible with sufficient strength, because the receiving groove, which is profiled only in a T-shape, also contributes to this.

Furthermore, the cavity and the reinforcement profile located therein can be angled to different widths at both ends, the wider angled end extending into the side fold flaps. The reinforcement profile at its shorter angled end can advantageously be additionally angled by 90 ° in the direction opposite to the receiving groove.

The hollow profiles described above can also easily be used to build a double-sash window frame. In this case, in the rebate area of one of the two hollow profiles opposite one another in the closed position of the window, a middle frame leg can be fastened to its inner profile web, which has a metallic reinforcement profile and a side fold flap forming an outer stop bar. For this purpose, the reinforcing profile of the middle frame leg can consist of a double-angled steel sheet with a profiled head-like profile, on the nail head of which protrudes beyond the casement profile, a stop bar provided with the latter encompassing a correspondingly undercut receiving groove and forming the side flap is pushed on is. A particularly narrow double-wing frame joint is achieved according to the invention if, on the side of the rebate air region opposite the middle frame leg, the side fold flaps originally present on the two wing frames and facing one another are cut off completely or partially UJ. , 1 on the remaining side fold flap stump of the m; c.tleren RahmenGr.henkel not supporting wing frame an _en other stop frame still internal stop bar is attached as a correspondingly corrected new side flaps. This can be unusual for double-sash windows in their middle sash joint area narrow, namely up to only 80 mm wide double frame dimensions can be achieved in the wing closed position.

Further features according to the invention are the subject of further subclaims and are described below with reference to several exemplary embodiments shown in the drawing. Show in the drawings

1 and 2 a vertical and horizontal section through a double casement window provided with fanlight sashes, the casement frame profiles of which are of the type according to the invention, FIG. 3 a horizontal section through a window area of natural size consisting of a frame and casement frame,

4 and 5 vertical sections through two upper window areas, FIGS. 6 and 7 horizontal sections through the sash frames opposite one another in double-sash windows, FIG. 8 a modified sash frame embodiment which is particularly suitable for the central area on double-sash windows and FIG. 9 shows a horizontal section through the central region of a double casement window, which is provided here with partially cut casement frame profiles from FIG. 8.

The double-sash window shown in FIGS. 1 and 2 in vertical and horizontal section has a permanently installed frame, which consists of the horizontal upper and lower frame bars 1, 1 'and the two vertical frame bars 1 "," and that in the upper part the window lying cross bar 1 ^IV , the so-called Loosholz exists. All these frame spars consist of plastic profiles 2 with rectangular profiled metallic reinforcing hollow profiles 3 inserted therein. Between the loosewood 1 ^IV and the upper cross member 1, the skylight wing 5, which can be opened inwards in the direction 4, is arranged, while between the cross member 1 ^IV and the lower cross member 1 ', two turn-tilt window sashes 6, 6' are arranged, which according to FIG. Position with their inner casement hollow profiles

7 and the middle frame leg 8, which is firmly connected to one of the two hollow profiles 7, meet in a sealing manner in the window center.

The window sash hollow profiles 7 used in the windows described above are of the nature shown in FIG. 3 in a natural size. They are made of extruded plastic and have on the outside a glass rebate recess 10 which serves to surround the window panes 9 and then have a central region M inwards, which consists of an inner profile web 11, an outer profile web

12 and an intermediate cavity 14 provided with a metallic reinforcement profile 13. The rebate air area F, which is flanked by the side fold flap S seated on the middle area M with a seal D embedded therein, adjoins the middle area M further inwards. The width-wise dimensions of the central region M are denoted by m, that of the rebate air region F by f, that of the side seam flap S by s and that of the sealing edge D by d. The width f of the rebate air area F is thus determined to be f = s-d. The width m of the central area M, as shown in FIG. 3, is only a few millimeters larger than the width f of the rebate air area F. This narrow construction of the central area is achieved here in that the cavity 14 lying in it is practically as narrow as the inner and is outer profile web 11 and 12 and by the correspondingly narrow steel reinforcement profile in its wall thickness

13 is largely filled out.

A simple T-shaped receiving groove 15 is formed in the inner profile web 11 and can be used to accommodate a wide variety of fitting parts. In the present case, this is a correspondingly profiled push rod 16 with a locking bolt 17 seated thereon. These can cooperate with locking parts (not shown) embedded in the groove 18 of the fixed frame 1. The cavity 14 as well as the reinforcement plate 13 located therein extend at both ends towards the rebate air area F and the T-shaped receiving groove is narrow-ended at a distance comprehensively angled, angled at different widths. The wider angled, doubly folded end 13 'extends into the side fold flap S, while the angled cavity end 14' receiving the shorter angled end 13 '' of the reinforcing plate 13 is designed as a screw region and, for this purpose, is narrow on both sides Extrusion clearances leaving screw rib 19 is partially filled.

The casement hollow profile of the type described above differs from conventional hollow profiles of a similar type, above all due to its extremely narrow central region M, whose width m is less than or equal to twice the rebate air width f, ie m≤2f. In the present case, the central area is extremely narrow, namely a total of only 15 mm wide. The small width of the simply grooved groove 15 also contributes to this. In spite of its narrow construction, the casement hollow profile 7 is extremely stable and in particular also torsionally rigid.

Advantageous examples of installation and use of the new casement hollow profile are shown in FIGS. 4 to 6. 4 could represent a vertical section through the upper edge of a window sash frame, a guide rail 20 being inserted into the receiving groove 15 of the inner profile web 11, in which the retaining bolt 22 of an extension arm lies above the push rod 21 and can be displaced to a limited extent is. The guide rail 20 is fastened to the inner profile web 11 by means of a plurality of fastening screws 23 by means of a screw fastening strip 20 ′ formed thereon.

In the case of FIG. 5, a corner deflecting rail 24 is inserted into the receiving groove 15 of the sash frame hollow profile 7 and is also fastened to the inner profile web 11 via a screw fastening bar 24 ′ and fastening screws 23 attached to it. The recess 24 ″ present in the corner deflecting rail 24 serves in its upper region to accommodate a corner deflecting belt, not shown. Fig. 6 shows the natural representation in

Fig. 2 reproduced central impact of the two vertical frame spars opposite each other in the closed position of the double window! ',! ''. Both frame bars are fully identical, but are arranged in mirror image to one another. On the sash frame spar 7 ', a central frame leg 25 is also attached in its rebate air area, which in the present case also consists of a plastic hollow profile 26 and contains a metallic reinforcing profile 27 lying therein. In the present case, this reinforcing profile 27 consists of a steel sheet which is angled essentially in the manner of a P profile and has two layers of angled layers and which, with its widened profile head 27 ', faces the blow bar 25' of the frame leg. In this blow bar, which at the same time forms the side fold flap 25 ″ of the middle frame leg 25, there is a dovetail-shaped undercut groove 28 into which a decorative bar 29 covering the frame leg 25 can be inserted.

In the embodiment shown in FIG. 7, the metallic reinforcement profiles 13 are additionally angled by 90 ° at their shorter angled ends 13 '' 'in the opposite direction to the associated receiving groove 15. As a result, greater stability can be achieved and, in particular, the screw fastening possibility for the central frame leg 25 can also be improved, since its fastening screws 25 '' 'can also be additionally screwed into the angled ends 13' '' of the steel reinforcement profiles 13 . Stability is also increased by the deeper angling of the profile head 27 'compared to FIG. 6 and its penetration through the fastening screw 25' ''.

A sash frame hollow profile that is particularly suitable for the central vertical spars of a double-sash window is shown in FIG. Its central area M is just as narrow in relation to its rebate air space F as it used to be. The steel reinforcement profile 13a does not have a double angled end protruding into the side fold flaps S of the sash frame hollow profile 7a. Rather own it here the inner profile web 11 containing the receiving groove 15, the cavity 14 partially encompassing it and the reinforcing profile 13a contained in the latter, an essentially plate-like profile. Since the side fold flap S is not reinforced with metal here, it can be easily separated, for example at positions 30 or 31, so that the double-profile design which is particularly narrow in FIG. 9 results. Here, on the left wing frame hollow profile 7a ', a likewise very narrow reinforcement profile 32 is screw-fastened, which here simply consists of a head nail-like profile, double-angled steel sheet, on the nail head 32' of which projects beyond the wing frame profile 7a ', one with the latter encompassing the latter , stop bar 33 provided correspondingly undercut receiving groove 33 'is pushed on. On the side of the rebate air area diagonally opposite the middle frame leg 32, the side fold flap S is here partially removed in accordance with the section line 30 in FIG. 8 and one on the remaining side fold flap stump S 'of the sash frame 7a''not supporting the middle frame leg the other sash frame 7a ', overlapping inner stop bar 34 attached as a correspondingly corrected new side fold flap. The side fold flap S lying on the opposite corner of the other casement 7a 'has been completely removed here at the interface 31 shown in FIG. Overall, the condition according to the invention also arises here that the width m of the wing profile center region M is less than twice the rebate air width f. In this way, an extremely narrow frame design can be achieved in the wing joint area of a double casement window, which also has the advantage of great strength and stability.

It goes without saying that various modifications are still possible within the scope of the present invention. For example, the sash frame hollow profile could in principle also be made of light metal, e.g. Aluminum.
