DK 160371 B

The present invention relates to a shutter or wing frame for windows or doors and of the kind specified in the preamble of claim 1.

Such an aperture or wing frame is known from EP-OS 5 No. 00 63 623 and is provided with a hollow, cross-sectional square main profile rod of plastic material, with notes formed on the four corners of the main profile rod, which are symmetrical as well as a a longitudinal plane of the rod through the rod and perpendicular to the plane of the frame as in relation to a plane longitudinally of the rod through the rod and in the plane of the frame, and with impingement ribs associated with the main profile rod.

A disadvantage of these known aperture or wing frames is the relatively costly, inextricable connection by means of point-wise mirror welding between the main profile rod and the impact rib moldings, which must either be established in the manufacture of the main profile rod or at the mounting location of such a frame. Furthermore, the inseparable connection between the main profile rod and the impact rib moldings at point 20 mirror welding at the establishment has the disadvantage that a fixed building element is then produced which can no longer be adapted to later conditions; On-site installation is problematic because mirror welding requires relatively expensive equipment and can therefore only be performed on a building site in rare cases.

It is therefore the object of the present invention to provide an aperture or wing frame for windows or doors, and of the kind indicated, in which the inseparable connection between the main profile bar and the impact rib moldings can be accomplished without difficulty in mounting the frame.

This task is solved according to the invention by means of the features specified in the characterizing part of claim 1.

Advantageous embodiments are defined by the features specified in the subclaims.

The advantages of the invention are due to the fact that the high profile rod on the one hand and the impact rib moldings on the other hand can be processed industrially and as needed, e.g.

DK 160371 B

2 when installing such a frame, and can easily be inserted into each other in such a way that the locking ribs on the impact rib moldings are inserted into a groove on the main profile. This connection is, because of the spatial configuration of the note on one side and the locking rib on the other hand, unlockable without damage to the main profile rod, respectively. the impact rib moldings so that it achieves the same function as a mirror welding, but without the associated disadvantages.

At the same time, this frame can be adapted as needed to the 10 existing conditions, as the impact rib moldings are only inserted into notes where it is required to get a special frame. Thus, one does not already have to fixate on a particular embodiment of the frame when manufacturing the main profile rod.

15 In each of the four notes on the main profile bar, a stop bar list can subsequently be inserted. The other notes in the main profile rod, which are not provided with a stop ribs list, can then, as needed, record a re-releaseable clamping list, but can also be used in another way, 20 for example for receiving connection springs.

In this way, with a main profile rod in connection with separate, irreplaceable insertable impact strips and releasably insertable edge filling strips, an extremely large number of different profiles can be produced, thereby greatly simplifying the production. In particular, a reduced inventory is obtained.

Significantly important is the design of the lockable ribs insertable in the corresponding groove on the abrasive grab bar. This must hold the separately extruded 30 impact grip strip in the groove, which must at the same time continue to be suitable also for recording the usual filling terminal strips.

A secure insertion of the locking rib is facilitated by its bevelled bevel from the locking projection towards its free edge.

When the locking rib completely fills the groove section in the area near the groove opening and narrows in the direction of the locks

DK 160371 B

3, a particularly secure positioning of the locking rib is achieved and thus a secure retention of the impact rib in the main profile rod.

Often it is sufficient if, as according to claim 4, 5 the locking rib near the groove abuts the desired width against the groove wall provided with a groove, the connection becomes firm, however, when according to claim 7 the locking rib protrudes into the groove with a flat elevation and grips the edge of the groove closest to the opening of the groove.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be described in more detail with reference to embodiments shown in the drawing. In the drawing:

FIG. 1 is a cross-section through a main profile rod formed in accordance with the invention; FIG. 2 is a cross-section through the abutment rib formed in accordance with the invention; FIG. 3 is a cross-section through a metal profile reinforced main profile rod which is provided on the outside with a stop rib rod according to claim 2 and on the inside side is provided with a conventional known filling terminal strip, so that, for example, between filling terminal strip and stop rib FIG. 4 is a substantially enlarged scale of the locking rib on the impact rib with the cooperating, correspondingly shaped retaining groove on the main profile rod; FIG. 5 is a section perpendicular to the plane of the window through a window formed in accordance with the invention, in which a fixed pane is combined with an outward opening wing; FIG. 6 further schematically shows the same window construction as in FIG. 5, in which the outward opening wings are formed of main profiles and impact ribs according to the invention; FIG. 7 is a partial sectional view of a two-wing window with wing frames according to the invention in section, the post in the middle of the window also being designed according to the invention; and FIG. 8-15 highly schematic options for combining in different ways a main profile bar according to the invention.

the invention with impact ribs according to the invention.

The FIG. 1, the main profile bar shown in cross section is made of a plastic suitable for window profile rods, such as, for example, a PVC-PE blend polymerisate. It has essentially a rectangular profile. According to FIG. 1, including the window plane from above and below perpendicular to the drawing plane. Both the two upper corners of the drawing and the two lower corners have the main profile rod 1 grooves 2. Each groove is thereby formed by means of the cavity between two 10 correspondingly from the rectangular main profile of the groove 3 and 4. the outer side of the profile bar, an outer, smaller side chamber 7 is separated by means of a connecting wall 6. parallel to the plane of the window. This side chamber 7 can serve to divert penetrated water. In this way, it keeps the main chamber 8 free of water, so that in this last metal reinforcing rod 9 can also consist of non-rust-free material. Furthermore, the wall 6 with the side chamber 7 ensures a good thermal insulation as any metal reinforcement 9 20 does not reach the outer surface 10 of the profile rod.

In each of the notes, a conventional and known filling terminal 12 can be releasably inserted by means of its holding rib 13. As regards the interaction of the note with the holding rib on the conventional filling terminal 12, the structure of the note 25 2 has also not changed in relation to the prior art point. In order for the groove 2 to cooperate with the locking rib 20 on one of FIG. 2, separately extruded impact rib 21 is the groove further profiled.

It is not to be further described here how the groove 30 2 interacts with the conventional holding rib 13 on the filling terminal strip 12, as this is well known through the window system "COMBI-DUR" negotiated by the applicant for several years.

In the following, it will be described how the locking ribs 20 on the impact rib bar 21 interact with one of the four grooves 2 on a main profile bar according to the invention.

FIG. 4 shows greatly enlarged those for as far as relevant.

DK 160371 B

5 shows parts of the right lower corner of FIG. 3. The groove 2 according to the invention differs from the conventional design of the corresponding groove only in that the groove shown in FIG. 4, right opposite the groove 24 of the groove 2, forming a shoulder 23 is retracted as shown in FIG. 4 approx. at a third of the groove depth. The groove 24 in the side of the groove corresponds to the prior art.

However, the locking rib 20 is substantially different in relation to the known holding rib. The locking rib 20 is in the area 10 at the foot 25 adjacent to the surface 24 of the abutment rib bar 21 as well as the holding rib 13 of the same width as the groove, so that it abuts on both side walls of the groove. At about half the height of the distance from the surface 26, where the groove is recessed to the shoulder 23, the locking rib leg 20 is laced on both sides. While on the right side only a flat wedge-shaped lace is placed, the lacing of FIG. 4 on the left side significantly larger. This larger incision facilitates the insertion of the locking rib 20, as it is provided by a locking projection 28 which 20 from above engages the shoulder 23 according to FIG. 4 again becomes wider. On top of the shoulder 23, the right limiting surface of the locking rib 20 extends obliquely to the left to the flattened tip of the locking rib 20. Above the lacing 29 on the groove side of the locking rib 20, the corresponding extension of FIG. 4, the left side surface of the locking rib corresponds to the corresponding surface of the foot region 15 and therein also abuts against the corresponding side wall of the groove 2. This wall portion of the locking rib 20 abuts the FIG. 4, left side wall of the groove 2, over the greater part of the height of the groove 24 may be simply extended 30, as also shown in FIG. 4. Already hereby, by proper dimensioning, as is approximately drawn in FIG. 4, a secure anchorage of the abutment rib bar 21. However, if a particularly good anchorage is obtained, the area of the locking ribs 24 placed on the groove 24 can be left out, as indicated by dashed lines in FIG. 4, project slightly, for example 0.5 mm, into the groove 24.

This provides double retention in cooperation with the locking device.

DK 160371 B

6 the projection 21 on the profile of the locking rib 20.

If the locking rib 20 is to be inserted into the groove 2, the abutment rib strip 21 for this purpose is set obliquely in such a way that in FIG. 4 shows the plane connecting the discharge of the tip 5 of the locking rib 20 to the right, lower projecting edge, at which the locking rib 20 borders the surface 22, extending approximately vertically from top to bottom. Then, the locking rib 20 is pressed into the groove 2 with a strong pressure so that it springs into the one shown in FIG. 4. Now a practically insoluble compound has been provided. By means of a similar dimensioning, it is possible, depending on the hardness of the material, to make the locking due to the shape of the parts correspondingly strong or less strong. The softer the material in the strip 21 and the rod 1 is, the easier it can be deformed, and the more it is necessary to allow the locking projection 28 to engage behind the shoulder 23. This has to take into account not only the locking rib 20 but also the two strips 3. and 4 are subjected to a corresponding deformation. With a correspondingly strong material, it may be necessary to use a corresponding tool for pressing the locking rib into the groove 2 which, on the one hand, attacks the strip 21 and on the other hand the profile rod 1. Here the principle applies that the greater the pressing force is, the stronger the compound produced. Of course, deformations occurring during the compression must be substantially within the range of elasticity of the material.

The locking rib 20 must be pre-loaded with the groove.

The once pressed impact rib 21 is no longer loosened without damage or at least disproportionately large deformation and in practice not applicable forces. It behaves differently at the filling terminal strip 12. If the pane held between the terminal strip 12 and the stop rib 21 is destroyed, the terminal strip 12 according to FIG. 3 loosen by oscillation opposite the clockwise direction again from the connection to the corresponding groove 2.

With regard to the more precise design of the locking rib 20 and the groove 2, reference is made explicitly to FIG. 4, which shows one

DK 160371 B

7 advantageous design. This also applies to the dimensions of the rib 20 and the groove 2 shown in FIG. 4th

The elements described so far can produce the most diverse frames for windows and doors. This 5 is explained below with reference to FIG. 8-15. In all of Figures 8-15, the left side of the only schematically indicated main profile rod 1 is the outer side of the frame.

Therefore, a small front chamber 7 is also located there.

In FIG. 8-15, only the placement of the impact rib 21 10 is drawn, while the other building elements for simplification purposes are omitted. In the embodiment of FIG. 8 there is only one abutment on the outside of the frame. This can, for example, serve as an estimate for a wing, but also as an estimate for a fixed pane.

15 In the embodiment of FIG. 9 is diagonally opposite to that of FIG. List 21 shown further 8 on the far right is another impact rib 21. This can then also serve as a wing impact.

In the embodiment of FIG. 10, abutment strips 21 are inserted in the two notes 20 2 on the outside of the frame.

Both can then serve as a wing attack as well as for the maintenance of a fixed window.

The embodiment of FIG. 11 is largely similar to the embodiment of FIG. 8. Here too, the impact rib bar 25 21 can serve both for wing impact and for maintaining a fixed pane.

In the embodiment of FIG. 12, for example, the upper abutment rib bar 21 in the figure is formed as a wing abutment, while the lower abutment 21 can also serve either as a wing abutment or for retaining a fixed pane.

In the design according to claim 13, moldings 21 are inserted on the inner side of the frame in the two grooves 2.

In the embodiment of FIG. 14, the frame 21, for example 35, also serves as a wing stop, as is the case in the embodiment of FIG. 15th

For easier understanding of the inventions there are at

8 FIG. 5 is a horizontal sectional view of a window arrangement made according to the invention, in which a fixed window is inserted in the left part, while in the right half there is an openable wing of conventional profile bars.

As shown in the drawing, the fixed pane consists of a circumferential left, above and below in the usual manner connected to the edge of the window opening, which is formed essentially of four main profile bars 1. While the left main profile rod 1 in the drawing is connected to At the edge of the window opening, the middle profile bar 1 is positioned freely in the opening and with its left edge holds the fixed pane 40, while its right edge forms an impact on the outward opening wing 50.

15 On the exterior side of the window, in the corresponding notes 2 on the four main profile bars 1 there is an irreplaceable inserting stop rib strip 21. Thereafter, in the usual way the insert of FIG. 1 to double it, the glass clamping strips 12 are then pressed in the conventional notes 2 in a conventional manner 2.

Should the fixed pane 40 not be a double pane, but a single pane, a somewhat different sized glass terminal 12 may be used instead of the glass terminal strip 12.

The outward opening wing 50 cooperates with an aperture-frame consisting of four main profile bars 1, of which the left main profile rod in the drawing coincides with the right profile rod in the drawing with the fixed glass 40. on the inner side of the pane in the corresponding notes 2 of the main profile rod 1 30 releasably inserted abutment ribs 21. With these thus formed abutment ribs, the wing 50 cooperates. This consists of four profiled rods 51 according to the prior art, which lists by means of externally projecting abutment ribs 52 is extruded integrally with the profile, from the outer side 35 abutting the main profile rods 1 and further cooperating with the impact rib strip 21 on the main profile rod 1. The conventional rods 51 are provided with bracket chambers 53 which

DK 160371 B

9 may similarly occur in the rods 1 of the invention.

The pane of the opening wing 50 is designated 55. Of course, a single pane can also be used here by means of 5 glass strips 12a.

In FIG. 5, the usual rubber seals inserted in the notes 30 are not shown. Such seals are also well known and quite common and need no further description.

FIG. 6 is a schematic diagram of a window arrangement similar to FIG. 5. In FIG. 6 is also the outside face upwards and the inside face down. Here, too, the wing 60 opens outwards, while in the left part as in FIG.

5, they draw a fixed pane 40 which is formed in the same manner as in FIG. 5. Unlike the structure of FIG. 5, the frame 62 of the opening wing 60 is also formed by the main profile rod 1 according to the invention with fitted impact ribs 21, and glass clamp strips 12. Here, too, the applied impact rib strips 21 are on the outside as they are more fixed in relation to the glass clamp strips 12.

In a construction as shown in FIG. 6 wing not open outwards, but inside, ie. thus, the outside side must face downwards, it must be taken into account that the retaining strips 21 must again lie on the outside.

In this case, therefore, the glass clamp strips 12 must be placed at the fixed window where the retaining rib strip 21 is drawn and vice versa. Furthermore, on the wing frame 60 and the pane holding retaining strips 21 and glass clamping strips 12 must be interchanged.

FIG. 7 shows a window structure with two outwardly extending wings 71, which abut against the vertical center of the window indicated by the center line 71 and having abutment against a fixed post 72. The construction of the wings 70 is below identical to that of FIG. 6, the post 72 is also formed here by a main profile rod 35 1 having on the inner side of the window two non-releasable impact rib strips 21, while the moldings 4 on the outside cooperate with corresponding impact rib strips 21 on the wing.

DK 160371 B

10 frames 75.

FIG. 7 may also serve as an illustration of an inwardly opening wing arrangement with a center post 72, assuming that the inner side faces upwards and the outside downwards. In this case, then, above all, the glass panes holding arrangement of abutment ribs 21 and glass clamping strips 12 must again be interchanged, so that the first of FIG. 7 are at the bottom and the last at the top.

The design according to the invention of the locking ribs for holding abutment ribs may also be advantageous when the design of the main profile rod does not correspond to the main claim, but when the main profile rod is thus formed, for example, corresponding to the rods 51 according to FIG. 5. It is also advantageous, for example, when the wing is a door wing having a filling in the middle which cannot be renewed. In that case, for example, the terminal strips 12 can be replaced by terminal strips 21.

Thus, the article of claim 4 may also be used independently of the configuration of the main profile rod of FIG. First
