Abstract

In a window or door construction comprising, arranged in a casement 1, multi-pane glazing in the form of a stepped double glazing unit 10, a shoulder 14 of a profiled part 13 of the casement engages under the shorter pane 11 of the stepped double glazing unit 10. The shoulder 14 has a receiving groove 18 for the insertion of an inner leg 20 of a holding piece 19, the holding piece engaging by a shorter, outer leg 21 round the outer edge of the double glazing unit. The outer leg runs at an acute angle and the inner leg at an obtuse angle with respect to the web 22 of the holding piece 19 which connects them, so that as the inner leg 20 is pressed increasingly into the receiving groove 18, the clamping force pressing the unit 10 against, on the room side, a bearing leg of the casement profile 13 increases. The web 22 is strengthened increasingly to the inside, so that, when the holding piece is fitted, an increased clamping force is also obtained in the plane of the unit. <IMAGE>

Description

The invention relates to a window or door construction according to the preamble of claim 1.

A construction of the generic type is known from DE-U-85 05 873. In this construction, an insulating glass pane is held on a casement profile by means of a substantially U-shaped holder, the holder engaging with its leg on the room side in a receiving groove of the casement profile. The tension between the outer leg of the holder and the room-side abutment leg of the airfoil is achieved by means of an all-round elastic strip which is supported against the room-side surface of the inner pane of the multi-pane glazing. Since the holder has to span the entire cross-sectional width of the multi-pane glazing and the elastic strip and engages in a groove protruding into the wing profile on the room side, the web of the holder is inevitably relatively long. Furthermore, since the forces acting on the pane and the weight of the pane have to be removed via the web of the holder, a support flange on the wing profile is required, which at least partially engages and supports the holder in the web area.

Despite the additional support, the multi-pane glazing cannot be held securely. By im Tolerances lying in the pane area can result in the elastic bar not producing a uniform, circumferential contact pressure. In addition, because of the length of the holder web and because of the constructive solution of the direct transfer of the forces into the web, no secure hold of the disk is guaranteed. For this reason, the construction also provides for an additional mounting of the pane over the frame, which at least overlaps the outer pane in the edge area over the same depth as the holder and exerts a compressive force on this and the outer pane, so that the pane in the closed state of the Wing is also held.

A secure fit of the insulating glass pane is not guaranteed either because tolerances occur during the pane production which, in the construction described above, would have to be accommodated solely by the seal lying against the inner pane surface. If additional suction and pressure forces are now exerted on the pane as a result of the influence of wind, then there are inevitably leaks in the edge region of the holder and in the region of the elastic seal, so that moisture can penetrate, for which no drainage device in the known construction is provided.

The invention is therefore based on the object of improving a window or door construction of the generic type in such a way that the structure is simplified, the mounting of the multi-pane glazing is improved both in the closed and in the open state of a wing and a suitable load transfer is made possible. A suitable design of the pane holder in the casement or cane frame should advantageously enable improved drainage at the same time.

The object is achieved according to the invention in that the outer leg of the multi-pane glazing Holder at an acute angle and the inner, leg of the holder on the room side are arranged at an obtuse angle to the web of the holder connecting them and that the receiving groove of the profile has a design and arrangement corresponding to the positive reception of the leg on the room side.

So that the edge of the outer glass pane is not gripped too far for optical reasons, but is only held by the holder and protected in the edge area, the outer leg of the holder has approximately half the length and thickness of the inner leg of the holder with which the holder in engages the receiving groove of the casement profile. The web of the holder can be increasingly reinforced on the room side, so that any forces which may have been introduced into the holder can be dissipated well into the frame profile. In the area of the engagement surface of the inclined inner leg, the parallel leg surfaces of the holder can be roughened or, for example, toothed, while the corresponding groove surfaces are machined accordingly, so that a secure hold or a latching of the holder takes place when the inner leg is pressed into the receiving groove. The receiving groove is longer than the inner leg of the holder and has an enlarged cross section at its end, so that there is sufficient space for receiving the end of the holder and tolerances can be compensated.

The holder can advantageously encompass the multi-pane glazing all around if it is made of plastic, for example, or at least attack on the four corners of the multi-pane glazing in the form of short pieces if it is made of metal, for example, since the material and the shape achieve sufficient inherent stability can be. In the case of a circumferentially designed holder, drainage bores or relaxation bores are arranged at a distance from one another in the web area, for example for steam pressure compensation, the width of which essentially extends over the entire rebate area can. The holder and the sash profile are advantageously arranged such that the web of the holder with a sash wall is substantially in the same plane and forms a wall of the fitting chamber. whereby the smallest possible depth of fitting to be covered, based on the frame edge, is achieved. In this case, either the holder can have a stop which engages into the fitting chamber, against which a center seal comes to rest when the sash is closed, or this stop can be provided on the fitting chamber wall of the sash frame.

In a particularly advantageous manner, the holder can be used in a window or door construction in which multi-pane glazing is used, which is formed by a step insulating glass pane. In this case, in order to shorten the holder in the web area, the wing profile can be extended into the rebate space below the inner, shortened pane of the stepped glass. The wing profile can have at least one shoulder on the section projecting into the rebate space, on which the load of the multi-pane glazing can be removed. The wind forces acting on the pane are therefore, like the weight of the pane, essentially diverted into the shoulder area of the casement, so that the holder alone assumes its protective and holding function in the area of the outer pane edge. The outer, elongated pane of the stepped glass forms an end stop for the insertion path of the holder when the holder is inserted with its inner leg into the receiving groove.

The construction described above has the further advantage that a deepest rebate space is formed between the outer edge of the outer pane and the space-side contact leg of the sash frame in the area of the fitting chamber, in which water which may have penetrated can accumulate in order to be able to accumulate in the holder provided drainage holes to be discharged into the dewatering chamber and from there in a manner known per se.

The drainage holes made possible by the gradation of the casement and the stepped glass at the lowest point of the pane ensure that water is drained off even if a holder that runs across the entire width of the pane and engages in the casement profile is not horizontal and even.

When using a wooden construction as a sash profile, it is advantageously provided that the section of the wooden profile protruding into the rebate space is reinforced by a metal fitting or that the receiving groove is provided in the metal fitting in order to ensure a secure hold of the holder. It is also conceivable here to extend the holder by means of a web protruding into the fitting chamber, which acts at the same time as an additional fastening of the holder to the wooden wing and as a stop for the center seal.

Further features, details and advantages result from the following description of preferred exemplary embodiments with reference to the drawing. In it show:

another embodiment for a sash.

In the construction according to the invention shown in FIG. 1, the glazing has a wing 1 and a fixed glazing 2. The fixed glazing consists of a conventional multi-pane glazing 3, which is received between an outer seal 4 and an inner seal 5. The outer seal 4 is held in the leg of an outer frame profile 6, while the inner seal 5 is held by means of a glass strip 7, which is supported on an inner frame profile 8. The outer frame profile 6 and the inner frame profile 8 are connected to each other by means of an insulating bridge 9.

The multi-pane glazing of the wing 1 is formed by a step insulating glass pane 10. It can be seen that the inner disc 11 is shortened compared to the outer disc 12, so that there is a step that allows the sash profile part 13 can engage with a shoulder 14 in the rebate space 15 and thus the shortened inner disc 11 engages. The forces that act on the pane in the vertical and horizontal directions can thereby be dissipated via the shoulder 14 in the vertical direction and via the spacer 16 and the silicone adhesive 17 into the casement profile part 13.

In the shoulder region 14 of the casement profile 13, a receiving groove 18 is provided, into which a holder 19 engages with its inner leg 20. With its outer leg 21, the holder 19 engages around the edge region of the outer pane 12, so that it is protected against damage and at the same time is held on the sash profile part 13.

2, the holder 19 is shown on an enlarged scale. It can be seen that the outer flange 21 is shortened and narrower than the inner flange 20 and that the web 22 connecting the flanges of the holder in the direction of the sash profile part 13 has an increasing reinforcement. The outer flange 21 is slightly inclined inward when the holder is not installed, so that a corresponding preload is generated when the holder is installed. The inclination of the inner leg 20 has the advantage that the holder can be easily inserted into the receiving groove 18 because the free end of the inclined leg in the mouth region of the groove enables the outer leg 21 to be at a certain distance from the outer glass pane 12 and only then comes to bear against them when the holder 19 engages in the groove and is pushed into it as far as possible. If the holder is pushed increasingly into the receiving groove 18, the outer leg 21 is pressed outward against its own prestressing force, so that the pane is pressed against the spacer 16 and the silicone adhesive 17 or, instead of the silicone adhesive, against a profile element with increasing contact pressure. The oblique arrangement of the inner leg 20 thus has the advantage that the insulating glass pane can be held securely on the sash profile part 13 despite manufacturing tolerances. The inward increasing reinforcement of the web 22 has the advantage that the holder has an increased inherent stability and, in particular in the case of glazing according to FIG. 3, that is to say with an extended web 22, receives additional prestressing against the edge of the pane.

The flanks of the receiving groove 18 or the inner leg 20 of the holder 19 have parallel leg surfaces so that the holder can be pushed further into the groove in accordance with the tolerances of the insulating glass pane, a greater clamping force of the outer leg 21 being countered by being pushed deeper into the groove the outer disc 12 is achieved. On the two legs of the obliquely extending holder section, a toothing 23 is preferably provided in the embodiment shown, which can engage with a corresponding toothing in the receiving groove 18, so that the holder 19 remains in its pressed-in position.

As can also be seen from FIG. 2, the holder 19 has drainage bores 24 and optionally additional relief bores for vapor pressure compensation, which are arranged at a distance from one another when the holder is rotating. The diameter of a bore 24 or the width of an opening, e.g. an elongated hole opening, the width of the rebate space 15 between the inner surface of the outer pane 12 and the end face facing the rebate space of the leg of the wing frame profile part 13 delimiting the receiving groove 18 may correspond. It can be seen that the drainage opening 24 is arranged at the deepest point of the rebate space 15, so that the condensed water can be drained into the drainage chamber 25 and from there in a manner known per se.

In the area of the upper end of the frame profile 6, a seal 26 is provided, which in the closed state bears against the outside of the outer pane 12 and thereby overlaps the outer leg 21 of the holder 19, so that in the closed state of the wing 1 there is no visual difference to the design of the fixed glazing 2 is recognizable.

In the embodiment shown in FIG. 3, instead of the stepped insulating glass pane 10, conventional multi-pane glazing 27 is provided, which is gripped by the holder 28. As in the exemplary embodiment according to FIG. 2, the holder 28 has a corresponding flange construction, so that reference can be made to the above description in this connection. It also has a stop 30 which engages in the fitting chamber 29 and comes to rest against a central seal 31 when the sash is closed.

1 and 3 that the holder 19, 28 is essentially in one plane with the section of the sash frame section 13 or 32 facing the fitting chamber 29 and together with the sash section section the Boundary wall for the fitting chamber 29 forms.

The exemplary embodiments in FIGS. 4 and 5 show fixed glazing with one-sided and two-sided arrangement of stepped insulating glass panes, which, as so-called structural glazing, are held only by holders 33, 34 and 35 on corresponding stick frame profiles 36 and 37, which are held in corresponding shoulder sections 38, 39, Have 40 grooves of the type shown in Fig. 1.

In the exemplary embodiments shown in FIGS. 6 and 7, wooden wings 41 and 42 and wooden rungs 43 and 44 are shown. The wooden wing 41 has a receiving groove 45, in which the inner leg 46 of a holder 47 is inserted. To reinforce the shoulder 48 of the wooden wing 41, a reinforcement angle 49 is provided, which e.g. can be nailed or screwed onto the shoulder.

In the exemplary embodiment shown in FIG. 7, the wooden wing 42 is equipped with a reinforcing strip 50, which has a flange section 53 which projects into the rebate space 51 of the step insulating glass pane 52 and which, with the vertical leg 54 of the reinforcing strip 50, delimits a receiving groove 55 in which the inner flange 56 of a holder 57 is received. The leg 54 also serves as a stop for the center seal.

FIG. 8 shows a so-called wooden sash 58 which has a wooden wing 59 and a wooden wing 60. When the sash is opened, the wooden wing 60 can remain as a rung, while the wooden wing 59 is swung open.

In FIG. 9, the holder 61 has, for the purpose of additional fastening, a web 62 reaching downwards, which also serves as a stop for the center seal.

The above-described wing construction according to the invention can be used due to the advantageous design of the holder in standard and system-compliant commercial profile systems with low glass rebate heights of approximately 20 to 26 mm. This means that an existing system can be supplemented by the construction according to the invention without the system program being restricted in its variability. For example, Fig. 1 shows a variant with wing and fixed glazing with a uniform external appearance. It can be clearly seen that the fixed glazing does not require an extended leg of the frame 6 compared to the existing optimized system program.
