Description

The invention relates to a glazing rebate insert with the features of the preamble of claim 1. The invention also relates to a system of at least one window frame profile and at least one glazing rebate insert according to the preamble of claim 7, and a method for glazing a window frame according to the preamble of claim 8.

According to the known prior art, the vast majority of windows in buildings consist of a glass element with a plate-shaped glass pane or several connected plate-shaped glass panes, which is carried by a window frame made of several window frame profiles connected at the corners. Depending on the application, the connected window frame profiles can form a blind frame, e.g. with fixed glazing or a sash frame, e.g. with openable windows.

A modern window should keep moisture out, reduce noise, be windproof and provide good thermal insulation. To ensure this, the glass element must be properly fixed in the window frame.

It is known that several glazing blocks can be installed in window frames, which are used for so-called blocking and are inserted in the air space between the edge faces of the glass element and a glazing rebate. A glazing rebate corresponds to a groove in each window frame profile of a frame of the window or window sash, in which the glass element is received at its edge. The glazing blocks create a cavity that can absorb the changes in shape or movements of the glass element. This cavity also serves as a vapor pressure equalization layer and as a support for rebate ventilation. This is particularly important if water vapor has formed. If this were not dissipated, moisture and pressure could create additional stress on the glass element and increase the risk of mould.

Glazing blocks are, for example, plastic plates, in particular with an at least substantially rectangular cross-section, preferably which are available in different thicknesses. Essentially, glazing blocks are therefore plastic blocks.

In addition, the glazing blocks fix the glass element in the frame. If the glass element were to hang loosely in the sash, the entire window would not be stable because the frame alone is not rigid enough. After a short time, the window would no longer close properly and would therefore be warped.

Another task of glazing packers is to properly distribute the weight of the glass panel on the frame. If this distribution did not take place, the window frame, e.g. a window casement frame, could sag and the window could no longer be closed.

Some window frame profiles are not always flat enough in the rebate area of the glazing rebate to allow the glazing block to rest over a sufficiently large area. Glass rebate inserts are provided to compensate for this. They compensate for unevenness and thus ensure a larger, especially level surface on which a glazing block can be attached.

For example, fold surfaces can be uneven in some areas if they include a drainage groove that runs, for example, in the transition area between the inner wall of the outer flap and the fold surface. A glazing rebate insert can cover such a fillet. Glazing rebate inserts also serve to locally hold a glazing block in place. For this purpose, holding arms, preferably flexibly movable holding arms, can be provided on the side edges of a glazing rebate insert, which lie opposite one another in the direction of extension of the window frame profile, which protrude at least in some areas beyond the level of the surface of the support plate of the glazing rebate insert and thus laterally encompass a glazing block placed on the support plate be able.

The glazing rebate in a window frame profile is partially filled by inserting, e.g. clipping, the glazing rebate insert into the groove of the glazing rebate and creates a larger, even contact surface for the glazing block. The support plate of a glazing rebate insert has a lower surface which, after insertion into the glazing rebate, faces the rebate surface and a surface on which a glazing block can then be placed. This can preferably be done on all four sides of the window frame, in the case of fixed glazing in the window frame or in the sash frame.

The glazing rebate insert thus levels the glazing rebate at least partially and, preferably with the shaping or structuring of its lower surface resting on the rebate surface, allows any water that may have penetrated the glazing rebate to run off.

According to the known state of the art, plate-shaped flat elements, referred to here as support plates, are used as glazing rebate inserts, which mostly consist of plastic. Glazing rebate inserts only serve to balance the rebate and/or to position a glazing block in the window frame profile and do not replace the glazing blocks. You must not come into contact with the glass element yourself.

Window frame profiles are preferably plastic hollow profiles, but can in principle also be aluminum profiles or wooden profiles, as well as composite profiles, e.g. made of plastic hollow profiles with aluminum facing shells or wooden profiles with aluminum facing shells.

Numerous solutions are known which describe the shaping of glazing rebate inserts for conventional glazing rebate grooves. So describes z. B. the utility model specification DE 20 2018 106 829 U1 a glazing rebate insert with retaining brackets to prevent the glazing block from slipping.

The glazing rebate insert known from this document is fastened in a resiliently clamped manner in the glazing rebate of a window frame profile. For this purpose, the known glazing rebate insert has fastening elements for clamping fastening in the glazing rebate on two opposite fastening edges. At least one fastening element is provided on an inner fastening edge, in order to be connected to an inner wall delimiting the rebate surface, to which the glazing bead groove is also attached bordering on working together. Furthermore, fastening elements are provided here on the outer fastening edge, which interact directly with an outer wall, which delimits the glazing rebate and at the same time also forms the inner wall of the outer overlap of the frame profile, which here merges into the groove of the glazing rebate without a step.

In the case of the known glazing rebate insert, the fastening elements on the outer fastening edge are designed in such a way that they protrude upwards over the surface of the support plate of the glazing rebate insert, on which the glazing block is placed. These fastening elements ensure that a glazing block placed on the surface of the support plate is kept at a distance from the inner wall of the outer flap.

The directions used in this description of the invention, such as inside, outside, up and down, refer to a typical installation situation on the lower horizontal window frame profile, e.g. a casement profile. The inner fastening edge of a glazing rebate insert is directed towards the interior or towards the glazing bead groove and the outer fastening edge towards the outside environment or the outer flap on the window frame profile. In this installation situation, the surface of the support plate of a glazing rebate insert points upwards so that a glazing block can be placed on it. The bottom faces down. When viewing other profiles, the direction information changes accordingly.

A resilient retaining arm is fastened to the two opposite side edges of the glazing rebate insert, which run essentially perpendicularly to the fastening edges, and which extends in regions over the plane of the surface of the support plate. The areas extending across the plane can interact with a glazing block in order to position it. A problem with this is that glazing rebate inserts are not usually designed to fit into every window frame profile with correspondingly varying glazing rebate grooves. In the case of special shapes of the glazing rebate, special glazing rebate inserts are therefore required, which can produce the final positioning of the glazing block with the glass element.

Thus, constructions of plastic hollow profiles, such as those with aluminum facing shells, for example, provide that the glass elements are very strong on the External flap must be pressed. However, it is difficult to subsequently move glass elements standing on the glazing block.

Furthermore, it is problematic with such window frame profiles to ensure that the glazing block protrudes sufficiently beyond the edge face of the glass element, since bringing the glass element close to the outer flap in its inner wall area does not provide enough space for the overhang of the glazing block, especially if such a mentioned state of the art with upstanding fasteners is used.

The object of the invention is therefore to provide a glazing rebate insert that ensures the positioning of a glazing block, in unity with a glass element arranged on it, even in window frame profiles with a confined space in the glazing rebate, in particular resulting from the special shape/special shape of an external flap. It is preferably also an object to achieve a defined position between the edge face of the glass element and the glazing block. It is also an object to provide a glazing rebate insert that is suitable, e.g .

This object is achieved with a generic glass rebate insert with the further characterizing features of claim 1. The object is also achieved by a system with the characterizing features of claim 7 and a method for producing a glazing of a window frame with the characterizing features of claim 9.

In the system, the invention preferably relates to window frame profiles, eg window sash frame profiles, in particular made of plastic, which have a sash stop or external flap without hollow chambers. Here, the outer flap or wing stop is used, for example, to attach aluminum shells / panels, for example. Such window (sash) frame profiles are on the outside overlap / sash stop e.g. single-walled and web-like and are characterized by a substantially vertical sash stop web/external rollover web, which ends on its inner wall in a rebate step, or on its inner wall via the rebate step into the glass rebate or an adjacent groove. In this embodiment, the groove of the glazing rebate is delimited on the outside by said rebate step, in particular not by the inner wall of the outer flap as in the prior art. On the inside, the glazing rebate groove is limited by a rebate step, which also forms a wall of the glazing bead groove. The glazing rebate, in particular also the rebate surface, is thus defined overall by the area that is formed between the two rebate steps and forms a groove together with the rebate steps. The groove or the fold surface can be lowered from the height level of the fold surface that is predominantly present, running parallel to and close to the outer fold step. As a result of the lowering, the channel already mentioned is formed, which can serve to guide water that has penetrated.

When pre-assembling the window, e.g. either lying on a brush table or in an upright frame, at least two glazing rebate inserts are fastened, e.g. clipped, in the glazing rebate between the rebate steps of the surrounding sash frame profiles. The two fold steps can each be undercut, especially when viewed from above in the direction of the fold surface, in particular in such a way that the groove at the bottom end of the respective fold step is wider than at the top end. Fastening elements on at least one of the fastening edges, preferably the fastening elements from both edges, can engage in such an undercut area.

A glazing fold insert of the type according to the invention can be created with its fastening elements on the outer fastening edge on the outside fold step and pivoted from above into the sash fold and fastened with the room-side fastening elements on the inner fastening edge on the inner fold step. Fastening can preferably take place in such a way that the fastening elements on the fastening edges are designed as latching lugs or clamping lugs, preferably resilient latching lugs or clamping lugs, which engage in the undercut areas of the fold steps, i.e. in particular in recesses under the upper step surfaces of the fold steps.

The glazing blocks are placed on the surface of the glazing rebate support plate, particularly on the grooved surface of the glazing rebate support plate. These lie between the retaining brackets and are thus positioned at least laterally, that is to say in the longitudinal direction of the window frame profiles.

After a glass element has been placed on a glazing block, these form a unit which, according to the design according to the invention, can be moved in the direction of the inner wall of the outer flap, since according to the invention the fastening elements of the glazing rebate insert arranged on the outer fastening edge are arranged at or below the level of the surface of the support plate. These fastening elements on the outer fastening edge therefore do not protrude beyond the level of the surface of the support plate. Preferably, all fasteners on the support plate are below the level of the surface or at most level with the surface. More preferably, at least the fastening elements are positioned on the outer fastening edge, preferably all within the thickness of the bearing plate, ie between the surface and the lower surface of the bearing plate. As a result, they do not protrude beyond the support plate on any side.

A glazing block sliding over the preferably grooved surface can thus slide over these fastening elements, in particular also over the step surface of the outer fold step, in particular to the extent that the glazing block strikes the inner wall of the outer flap above the fold step.

Preferably, the invention can provide that the holding arms have at their free ends towards one another, preferably tapering projections. The projections, which at least initially act like retaining hooks, hold a glazing block in a spaced-apart position relative to the inner wall of the outer flap, forwards in the direction of the wing flap/outer flap. For this purpose, the glazing block can be pressed with its edge pointing towards the outside flap until it comes into contact with the projections. The lateral retaining brackets prevent lateral displacement of the glazing block and form a desired distance from the inner wall. In particular when mounting the frame upright, the lateral Holding bracket prevents the glazing block from slipping out of the glazing rebate inserts. Towards the front, towards the sash stop, the projections act as a temporary stop for the glazing block.

Preferably, the free ends of the holding arms, in particular their mutually facing projections, viewed in the direction in which the holding arms extend from the inner to the outer fastening edge, can protrude beyond the outer fastening edge, in particular protrude beyond the fastening elements on the outer fastening edge. In this embodiment, the free ends form the elements of the glazing rebate insert that protrude furthest in the direction of the inner wall of the outer flap. In the mounted state, the projections on the free ends can then even lie above the step surface of the outer fold step. This design makes it easier to maintain a certain desired distance between the glazing block and the inner wall of the outer flap when the glazing block is first placed on the support plate.

It can be provided that after the glazing block has been positioned in contact with the projections on the free ends of the retaining arms when a glass element is lowered onto the glazing block, in particular in contact along the seal in the external flap, the edge face of the glass element is positioned in relation to the glazing block in such a way that a desired or the required overhang of the glazing block over the edge face is achieved.

By shifting the unit of glass element and glazing block, the projections and thus the free ends of the retaining arms are displaced to the side, so that the glazing block penetrates through the free ends and the projections in the direction of the inner wall of the outer flap through the projections.

This can preferably be supported in that the wall of each projection on the side pointing towards the outer fastening edge has an increasing distance towards the outer fastening edge in each case in the direction of the tip of the projection. As a result, a starting bevel is formed on the projections for the glazing block, via which the retaining arms are pushed to the side.

It can also be provided that the holding arms in an area between the projections on the free end and the location of the connection to the support plate in Are angled / kinked towards each other, in particular are angled from a position that is parallel to and preferably spaced from a glazing block that can be placed on it. The development can be closer to the outer fastening edge than to the inner fastening edge, based on the overall extension of a holding arm. Such processing forms a headband bevel. Provision can be made for the retaining arms to come into contact with a glazing block only in this angled area, in particular the end pointing towards the projection, but otherwise the retaining arms run at a distance from the glazing block. In this case, the glazing block is only held laterally in the kinked / angled area.

The retaining bracket bevels in the end section of the retaining bracket bring an advantage, along which the glazing block is forced to slide on the way to the projections when it is inserted. As a result, a glazing block that is narrower than the distance between the retaining arms in the area that is not bent is centered exactly on the glazing rebate insert. The bevels of the retaining brackets can also initiate a widening of the retaining brackets during this work step, especially if a glazing block has a width that is greater than the distance between the free ends of the retaining arms in the angled area in front of the projections and is smaller than the distance between the retaining arms in the area in front of the deflection. Even then, the projections still form the stop for the glazing block with regard to the displaceability in the direction of the external rollover.

The glass element is inserted and due to the heavy load of the glass, it forms into the softer glazing block - usually made of plastic - and forms a unit with it.

The remaining glazing blocks can be used on the other sides of the frame, e.g. with the help of a glazing lever. This tool is used to lever open the gap between the glazing rebate insert and the glass element in order to position the glazing block.

The first step of glazing is complete when the glazing panel is framed and supported by the glazing blocks, which in turn are held by the glazing rebate inserts. The glass elements are above the glazing blocks against the stop with the retaining bracket projections and the glazing seal on the outer flap.

In the final step, the glazing beads are inserted and the wedge seal is inserted from above into the gap between the glass element and the glazing bead. The pane element is pressed between the outer glazing seal and the inner wedge seal, as if between two clamping jaws. The seals are compressed from rest to a predetermined level to achieve an effective seal.

This process requires centering by moving the glass element in the glass rebate. Since there is already a mechanical bond between the hard, heavy and sharp-edged glass element and the glazing block, the desired shifts take place in the plane between the glazing block and the surface of the support plate of the glazing rebate insert. The thrust direction is in the direction of the outside wing stop / outside rollover.

The glass blocks take the glass pane clamped between them in the direction of the outside sash stop.

The glazing rebate insert preferably has a grooved surface in order to offer the lowest possible frictional resistance to the glazing blocks. The glazing rebate insert is constructed in such a way that the glazing block retains its position between the retaining brackets of the glazing rebate insert and shifting in the longitudinal direction of the sash frame profile is still prevented, but a thrust direction transverse to the window frame profile towards the sash stop / external rebate is still possible.

Preferably in connection with the special rebate step profile shape in the glazing rebate, it is provided that by knocking in the glazing bead or pressing in the seal on the glazing bead, the glass element with the glazing block, which was still held in the projections of the retaining bracket, shifts and as a result the retaining bracket now completely diverge so that the glazing block moves out of the hook-shaped headband projections, and preferably the glazing block is pushed freely and in particular so far up to the wing stop until the glazing block on the wing stop contact surface or the Inner wall of the outer flap abuts. The retaining brackets lock the glazing block against longitudinal displacement at all times and the retaining brackets are in the final position completely laterally next to the glazing block with retaining bracket projections abutting thereon.

In the final position, the glass element is completely on the glazing block and this is in turn, in particular at least 1 mm, under the glazing seal.

The invention is explained in more detail below with reference to the drawings.

figure 1 1 shows a closed window casement 100 of a window or a door made of several window casement frame profiles 10 in a cross section through the lower horizontal profile area. A glass rebate 11 is formed between the rebate steps 12 and 12′. A glass element 20 is about the seals 15 and 51 between enclosed by a glazing bead 50 and the outer flap/wing flap 13 and stands with its edge face directly on the glazing rebate via a glazing rebate insert 30 inserted into a glazing rebate 11 and a glass block 40 placed on the glazing rebate insert 30.

The window casement profile 10 is a PVC core profile that is covered with aluminum shells 16 on both sides. Apart from the seal, the glazing bead 50 consists entirely of aluminium. The material pairing of PVC and aluminum optimally combines the advantageous corner welding connection options of PVC profiles with the ideal surface properties of the aluminum shells 16. The sash stop/outer flap 13 is formed by a single-walled web and is not provided with hollow chambers, as is the case with conventional PVC profiles, which usually have an undercut in the transition to the glazing rebate 11 .

In the embodiment shown here, there is a fold step 12 at the lower end of the inner wall of the outer flap 13, which is followed by the drainage groove 17. This fillet is formed by a partially sunken area in the glazing rebate that runs in front of the rebate step. The area between the fold steps 12 and 12' forms the glazing fold overall, in which the glazing fold insert 30 is fastened in a clamping or latching manner, e.g. is clipped.

The glazing block 40 rests flush on the surface of the support plate of the glazing rebate insert 30 and is flush, preferably in contact with the vertical inner wall 13 ′ of the outer flap 13 . The glass element 20 forms a unit with the glass block 40 . Due to the high weight of the glass element, the two elements are connected to each other in a form-fitting manner and can only be moved together.

Figure 1a shows a detailed view figure 1 with glazing rebate insert 30 and glazing block 40. The glazing rebate insert 30 is fastened in the glazing rebate 11, between the rebate steps 12 and 12', eg clipped. According to the invention, there are preferably three height levels, which are clearly visible in this view. The glass inlay level a corresponds to the level of the surface of the support plate, which is preferably designed as a grooved support surface 37 . The side brackets 33 are attached to the side of the support plate and rise from level a at an angle upwards to level b of the brackets, which is the surface of the brackets and continue from there, preferably parallel next to the glazing block 40. Its upper surface is at a level c and forms the support plane of the glass element 20. The retaining bracket level b is lower than the level c of the glass element 20.

figure 2 shows the glass rebate insert 30 in plan view.

The glazing rebate insert 30 has a support plate with a surface 37 that is preferably grooved in this embodiment, which is suitable for offering little frictional resistance to the glass block 40 lying on it. The grooves preferably run parallel to the side edges of the support plate, which connect the fastening edges to the fastening elements 35, 36 or in the direction of the spacing of the fastening edges to the fastening elements 35, 36. The surface can also have a different structure. The direction of the grooves thus corresponds to the direction of displacement of the glazing block.

The glazing fold insert 30 has clamping lugs or latching lugs 35 on the outer fastening edge B1, which are provided in order to latch or clamp into the undercut area on the fold step 12. The lugs 35 can have an end face that is complementary to the contact surface of the fold step 12 pointing into the glass fold. Furthermore, the clamping lugs/locking lugs 35 can be made of softer PVC than the window frame profile. They can be arranged on elastically resilient, curved spring webs 35', e.g. The spring bars 35' can be offset from the outer fastening edge B1 towards the inside of the support plate, in particular so that at least the window bars 35' recede behind the fastening edge B1 and only the locking/clamping lugs 35 protrude.

The fastening elements 36 are arranged on the inner fastening edge B2, which also form locking lugs or clamping lugs 36, for example, these are also arranged on spring bars 36′, in particular which are part of the fastening edge B2 here and can be formed by recesses in the support plate behind the fastening elements 36. These fasteners 36 interact with the inner rebate step 12' which is also part of the glazing bead groove.

According to the invention, at least the fastening elements 35 are arranged in such a way that they do not project upwards beyond the surface 37 which is grooved here.

Retaining brackets 33 are formed on the side of the support plate of the glazing rebate insert 30, which - as in figure 3 shown, which have Sections I-IV.

As in figure 2 As shown, the retaining bracket 33 has a first section I which has a material connection with the support plate at and/or below the grooved surface 37 and which corresponds to the aforementioned glazing rebate insert level a. The retaining clip 33 forms a gap 38 to the preferably grooved surface 37 in sections II, III and IV, ie outside the connection area when viewed from above. In section IV, the retaining arms 33 are bent towards one another. They run there at headband level b and obliquely to the grooves in the surface 37. How Figure 1a the free ends clearly lie above the surface of the folding step 12, which can be level with the surface 37 or lower than it.

Essential to the invention, the glazing rebate insert 30 has retaining brackets 33, which can be bent open in an elastically resilient manner, in the sense that the free ends can move away from one another. At the free end of each retaining clip 33 there is a tapering projection 34, in particular one that tapers to a point. the projections 34 of both brackets are directed towards each other.

figure 3 shows the glass rebate insert 30 in side view. In this preferred embodiment, support webs 31 can be seen on the underside, with which the support plate is placed on the glass rebate surface between the rebate steps 12, 12'.

The glazing rebate insert 30 has a first section I and a second section II on the retaining brackets 33, which leads upwards at an angle, preferably a flat angle, to the glazing rebate surface and the support plate, in particular rising to the retaining bracket level b. The third section III runs parallel at the headband level b above the surface 37 of the support plate, the headband level b being above the glazing rebate insert level a. The headband 33 preferably runs after its rising area, ie in the areas III and IV at such a height that at least the surface of the headband lies above the surface 37 of the support plate, so that a lying thereon Glazing block is guided laterally. Preferably, the respective holding bracket also lies with its lower surface in some areas, in particular in the areas III and IV, above the surface 37 of the support plate.

figure 4 shows the glazing rebate insert 30 in a perspective view. The resiliently elastic latching lugs/clamping lugs 35 on the curved spring bars 35', as well as the latching lugs/clamping lugs 36 on the elastically resilient spring bars 36', enable simple attachment, e.g. clipping of the glazing rebate insert 30 in the glazing rebate 11 between the fold levels. Then the surface of the support plate of the glazing rebate insert is level with the upper step surface of the fold steps 12 and 12', preferably the upper step surfaces are lower than the surface 37. The drainage recesses 32 can drain condensation into the glazing rebate between the support webs 31 and from there into the frame .

The side retaining brackets 33, which form a lateral locking mechanism when the glass block 40 is inserted due to the increasing height level, are clearly visible.

figure 5 shows the assembled state of glazing rebate insert 30 in window casement frame profile 10 in a perspective view. The latching lugs/clamping lugs 35 lie in the glazing rebate 11 and are clipped into the rebate step 12 on the face side. The retaining brackets 33 protrude at the retaining bracket level b above and in front of the groove bearing surface 37 into the extended fold base A, which is formed here by the step surface of the fold step 12 .

the Figure 2a clarifies the inventive effect of the glass rebate insert. Here it can be seen in the top view that a glazing block 40 is placed on the grooved surface 37 of the support plate. the glazing block is guided laterally between the retaining brackets 33 . The edge of the glazing block pointing to the outside flap is held back by the projections 34 on the free ends of the holding arms against pushing too far in the direction of the outside flap. Due to the sloping area 33' at the free end of the retaining arms, these only rest against the glazing block at the free end, but otherwise run at a distance from the glazing block 30.

A glass element can be placed on the glazing block 40 in this illustrated position. After this, the glass element (not shown here) can be included Glazing block 40 are pushed further towards the outer flap 13, which is facilitated by the grooved surface 37.

Figure 2b shows that the sliding of the glazing block 40 passes between the projections 34 and then the edge pointing to the outside flap lies in front of the projections 34 . In this position, the edge is also arranged above the step surface of the fold step 12 and can come into contact with the inner wall 13' of the outer flap 13.
