The corner bearing includes a mounting bracket, which is inserted into a corner of the fixed frame on the rebate side and bolted to the fixed frame. On the side opposite the horizontal folding surface of the fixed frame side of the mounting bracket a Ausstellschere the corner bearing is arranged, which in turn has two scissor arms. These are perpendicular to the horizontal rebate surface of the fixed frame over each other and engage at their remote from the mounting bracket free ends in the wings to be stored. By means of the Ausstellschere the wing is guided in its movement relative to the fixed frame. The wing load is removed via the scissor arms in the fixed frame. For this purpose, the known corner bearing is provided in addition to the screw connection between the mounting bracket and fixed frame with a bearing projection which engages from the folding side of the fixed frame in the vertical direction in the fixed frame.

Generic prior art is known from US 3,145,414 A ,

The prior publication relates to a swinging door with a bottom-side pivot bearing. The previously known pivot bearing engages on the one hand with a journal in the door to be stored and on the other hand with a screw in a door sill. On the opposite side of the bearing journal of the threshold sits on the bolt a stepped in the axial direction of the bolt nut. With a reduced diameter axial section, the nut engages in the penetrated by the bolt opening of the door sill. A radially extended axial portion of the nut abuts against the underside of the door sill.

A fitting arrangement as well as a window, door or the like ready, in the case of heavy wings, in particular wings with a sash weight of 130 kg and more, can be stored by retrofitting less load-bearing fitting arrangements on a fixed frame, is the object of the present invention.

This object is achieved according to the invention by the fitting arrangement according to claim 1 and by the window, the door or the like according to claim 2.

The bearing projection of the claimed fitting arrangement is supported by an abutment. The anvil comprises an abutment base and an abutment projection provided thereon. The latter engages in the opposite direction of the bearing projection in the fixed frame and supports the bearing projection against tilting in the transverse direction of the main plane of the window, the door or the like. Due to the use of the counter bearing can be with the Fitting arrangement also high sash weights, in particular sash weights of 130 kilograms and more, ablate in the fixed frame, without unwanted deformations and / or damage to the relevant window, door or the like would be feared. The counter-bearing causes a stiffening of the fixed frame, which is especially useful in cases in which the fixed frame itself has only a limited carrying capacity. Stiffening according to particular solid frame, which are made of wood or hollow sections, for example made of plastic hollow sections or metal, especially aluminum hollow sections. Of particular advantage is the fact that abutment according to the invention can readily be used in combination with the hardware arrangements of the prior art described above. Accordingly, arrangements according to the invention can also be provided solely by retrofitting the previously known arrangements.

Particular embodiments of the devices described in the independent claims 1 and 2 emerge from the dependent claims 3 to 9.

Features that allow in a preferred embodiment of the invention, a structurally simple and therefore inexpensive fitting execution, can be found in the claims 3 to 5.

In the case of Erfindungsbauarten according to claims 3 and 4 also special measures to take into account the power flow are made, which adjusts to fitting arrangements according to the invention. The evidenced claim 4 sickle shape of the wall cross-section of the counter bearing can be finished in a simple manner by existing on a full material and a circular Cross-section having blank of an abutment projection a with the blank axis-parallel but eccentric bore is created.

The counter-bearing base is designed as an abutment base plate in view of the space-constrained installation conditions on the fixed frame according to the invention windows, doors or the like.

The connection between abutment base and abutment projection of the abutment according to the invention can be prepared in a variety of ways (claim 5).

The verweislich claim 6 in another preferred embodiment of the invention provided mutual offset of the counter bearing projection and abutment base of the abutment allows to arrange the abutment base on the remote from the folding side of the fixed frame fixed frame opposite side with a greater distance from the opening-side boundary of the fixed frame than that in the interior of the Fixed frame received counter bearing projection. Of particular importance are the inventive features of claim 6 for cases in which the fixed frame is provided at the side remote from the folding side fixed frame opposite side and there near the opening side of the fixed frame with one or more frame projections. Such frame projections would hinder the mounting of the counter-bearing base near the opening side of the fixed frame and would therefore have to be at least partially removed prior to the installation of the counter-bearing according to the invention. This additional assembly step is eliminated if, as provided according to the claim, the counter-bearing base with sufficient distance from the opening side of the fixed frame and thus adjacent to the one or more projections of the fixed frame can be arranged. Frame projections of the described Type are mainly provided on the fixed frame of plastic windows and plastic doors.

For practice particularly relevant applications of the invention relate to claims 7 and 8.

According to claim 7 is in the fitting assembly according to the invention is a concealed fitting arrangement with at least two links, which are housed invisible with a closed wing from the outside in a fold between the wing and the fixed frame. At least one of the links is supported on the fixed frame via the bearing projection which engages in the fixed frame from the folding side of the fixed frame. In the case of such fitting arrangements, the wing weight force to be removed in the fixed frame has a relatively long lever arm, in particular when the wing is open. The load that is introduced into the fixed frame via the fitting arrangement is correspondingly large. The thrust bearing according to the invention ensures, in particular for large sash weights, a functionally reliable load transfer without undesired deformations and / or damage, in particular to the fixed frame.

As shown in claim 8, the concept according to the invention is applied to a solid frame designed as a hollow profile frame and thus to a frame type which inherently only has a limited load-bearing capacity.

According to claim 9, the interior of the fixed frame is sealed in a further preferred embodiment of the invention in the region of the anvil to the outside. This can in particular be prevented that moisture or impurities in the interior of the fixed frame and from there into the interior of the relevant window, the enter relevant door or the like provided space. As seals in question, for example, come O-rings, flat and molded silicone gaskets.

According to FIG. 1 has a window 1 made of plastic in the usual way a wing 2 and a fixed frame 3. About a hidden and therefore not visible with closed wing 2 fitting the wing 2 is rotatable on the fixed frame 3 about a vertical axis of rotation and tiltable about a horizontal tilt axis stored. Part of the concealed fitting is a fitting arrangement in the form of a corner bearing 4, of which in FIG. 1 an abutment base 5 of an abutment 6 can be seen.

Further details of the corner bearing 4 are in the Figures 2 and 3 shown.

evidenced FIG. 2 the corner bearing 4 comprises a corner bearing bracket 7, which is inserted at a folded side 8 of the fixed frame 3 in a corner of the fixed frame 3. On a horizontal angle leg 9 and on a vertical angle leg 10, the corner bearing angle 7 is bolted to a horizontal spar 11 and to a vertical spar 12 of the fixed frame 3. In addition, positioning projections 13 of the corner bearing bracket 7 engage in associated receptacles on the fixed frame 3.

At the top of the horizontal angle leg 9 of the Ecklagerwinkels 7 designed as X-scissors Ausstellschere 14 of the corner bearing 4 is provided. The Ausstellschere 14 includes in a known manner two oppositely bent handlebars 15, 16, the closed wing 2 in a fold 17 (FIG. FIG. 3 ) lie one above the other between the wing 2 and the fixed frame 3. When opening and closing movements of the wing 2 relative to the fixed frame 3, the Ausstellschere 14 the wing 2 relative to the fixed frame 3 perpendicular to the main plane of the window first

The links 15, 16 are articulated on the one hand to the wing 2 and on the other hand to the corner bearing bracket 7 of the corner bearing 4.

The wing 2 shown by way of example has a sash weight of 130 kilograms. The sash weight is introduced via the Ausstellschere 14 in the Ecklagerwinkel 7 of the corner bearing 4. From the corner bearing bracket 7, the load acting thereon in the fixed frame 3 of the window 1 is to be removed. This function takes on the one provided for between the Ecklagerwinkel 7 and the fixed frame 3 screw. In addition, the corner bearing 4 has at the bottom of the horizontal angle leg 9 of the Ecklagerwinkels 7 a bearing projection 18, which is associated with an abutment projection 19 of the abutment 6. The bearing projection 18 consists of a circular-cylindrical bearing journal 20 and a pin journal 21 seated on the bearing journal 20 in a precisely fitting manner. The journal 20 is provided on the handlebar 16 of the jack 14, the journal 21 on the horizontal angle leg 9 of the corner bearing 7. From the folded side 8 of the fixed frame 3 forth the bearing projection 18 immersed in the vertical projection direction in the horizontal beam 11 of the fixed frame 3 a.

In the vertical opposite direction of the abutment projection 19 of the abutment 6 engages from one of the folding side 8 of the fixed frame 3 opposite fixed frame opposite side 22 forth in the horizontal spar 11 of the fixed frame 3 a. The counter-projection 19 forms in the example shown a concentric with the bearing projection 18 abutment sleeve. In the vertical direction of the abutment projection 19 overlaps with the bearing projection 18 over its entire axial length. In addition, the abutment projection 19 encloses the bearing projection 18 accurately and consequently with at most minimal radial clearance.

At its the fixed frame opposite side 22 associated longitudinal end of the abutment projection 19 is secured to the laterally opposite the abutment projection 19 projecting abutment base 5 of the abutment 6. The counter-bearing base 5 is designed as an abutment base plate and screwed at a radial distance from the abutment projection 19 with the horizontal spar 11 of the fixed frame 3. Overall, the anvil 6 has an angular shape.

The fixed frame 3 is formed as a hollow profile frame made of plastic and has as such in its interior a plurality of hollow chambers. In a hollow chamber 23 of the fixed frame 3, a stiffening profile 24 is inserted in the usual manner ( FIG. 3 ). In the stiffening profile 24 engage three of the total of five mounting screws for the anvil 6 a. The two remaining fastening screws of the thrust bearing 6 are screwed into the plastic material of the fixed frame 3.

The abutment projection 19 of the abutment 6 with the bearing projection 18 received therein is located inside a bore 25 which has been created on the fixed frame 3 near the visible to an opening side 26 of the fixed frame 3 visible surface of the fixed frame 3. The opening side 26 is that side of the fixed frame 3 on which the wing 2 is movable relative to the fixed frame 3. A trained as an O-ring seal 27 is seated on the abutment projection 19 and seals the serving for receiving the abutment projection 19 bore 25 in the interior of the fixed frame 3 against the outside from.

Like from the FIGS. 1 and 3 shows, the fixed frame 3, for example, on the fixed frame opposite side 22 is provided with projecting moldings 28. For mounting the corner bearing 4, the profile strips 28 in the area in which the counter-bearing base 5 of the thrust bearing 6 comes to rest, to remove. To the opening side 26 of the fixed frame. 3 Side profile strip 28 can be left near the counter bearing base 5 partially.

As an item that is in the FIGS. 1 to 3 shown counter bearing 6 in the FIGS. 4a, 4b, 4c shown. The sleeve-like abutment projection 19 is therefore inserted with its respective axial end in a suitably sized blind bore 29 of the abutment base 5 and soldered to the counter bearing base 5.

Instead of the anvil 6 according to the FIGS. 4a, 4b, 4c can the corner bearing 4 a counter bearing 6/1 ( FIGS. 5a, 5b, 5c ), an abutment 6/2 ( Figures 6a, 6b, 6c ) or an abutment 6/3 ( Figures 7a, 7b, 7c ) exhibit. Both FIGS. 5b . 6b . 7b are sectional views whose sectional planes in the FIGS. 5a . 6a . 7a are indicated.

In the case of the thrust bearing 6/1, a counter bearing projection 19/1 deviating from the abutment projection 19 of the abutment 6 is designed only over a part of its axial length as an abutment sleeve. To produce the counter-bearing sleeve, a circular cylindrical and made of a solid material blank for the counter-projection 19/1 was provided over a part of its axial length with a central bore. At its end facing an abutment base 5/1 an eccentric mounting pin 30 was created with a deviating from the circular cross-section of the blank for the abutment projection 19/1. With the mounting pin 30 of the abutment projection 19/1 engages in a corresponding passage opening 31 on the abutment base 5/1. Jointly secure the mounting pin 30 and the passage opening 31 the abutment projection 19/1 positively against unwanted rotation relative to the abutment base 5/1. In addition, the abutment projection 19/1 and the abutment base 5/1 are welded to each other at the attachment pin 30.

The passage opening 31 is arranged on the abutment base 5/1 such that, when the abutment 6/1 is mounted, there is a mutual lateral offset between the abutment projection 19/1 and the abutment base 5/1 ( FIG. 5c ). If the thrust bearing 6/1 used instead of the thrust bearing 6 for receiving the bearing projection 18 of the corner bearing 4, so may on the fixed frame 3 - deviating from the conditions according to FIG. 3 - Which are located on the opening side 26 of the fixed frame 3 out profile strip 28 on the fixed frame 3 completely. In that regard, the assembly of the corner bearing 4 simplified.

A corresponding advantage brings the use of the abutment 6/2 according to the Figures 6a, 6b, 6c with himself. Notwithstanding the abutment 6/1 6/2 an abutment projection 19/2 riveted to a rivet pin 32 with a counter bearing 5/2 in the case of the thrust bearing. Incidentally, the counter bearing 6/1 and 6/2 are identical.

The counter bearing 6/3 according to Figures 7a, 7b, 7c includes an abutment projection 19/3, unlike the abutment projections 19, 19/1, 19/2 no circumferentially closed sleeve but rather a circumferentially partially open receptacle for the bearing projection 18 has. This receptacle has a receiving wall 33 which is crescent-shaped in cross section.

To produce the counter bearing projection 19/3 a corresponding circular cylindrical blank made of full material was provided with an eccentric longitudinal bore. At a rivet pin 34 of the abutment projection 19/3 riveted to an abutment base 5/3 and also positively secured against rotation. A mutual lateral offset of counter bearing projection 19/3 and counter bearing 5/3 is not provided. Accordingly, even when using the anvil 6/3 on the fixed frame 3 to the opening side 26 of the fixed frame 3 out side profile strip 28 to remove partially.

Regardless of the type of counter-bearing used, the corner bearing 4 ensures a functionally reliable introduction of the weight of the wing 2 in the fixed frame 3. Especially with the wing 2 open, the sash force on the Ausstellschere 14 engages with a relatively long lever arm on the fixed frame 3. The wing 2 is consequently anxious to tilt the bearing projection 18 of the corner bearing 4 with its towards the folding side 8 of the fixed frame 3 towards the end towards the opening side 26 of the fixed frame 3. Such a tilting movement and the resulting deformations and / or damage to the fixed frame 3 and / or to the corner bearing 4 or to further provided between the wing 2 and the fixed frame 3 fittings acts the anvil 6, 6/1, 6/2 , 6/3 contrary. It supports the bearing projection 18 against a tilting movement in the direction of the opening side 26 of the fixed frame 3. Of essential importance is performed as a screw support of the abutment base 5, 5/1, 5/2, 5/3 on the Festrahmengegenseite 22nd This support or screw is prevented that the counter bearing 5, 5/1, 5/2, 5/3 and with this their associated end of the abutment projection 19, 19/1, 19/2, 19/3 under load of the opening side 26 of the fixed frame 3 moves away. To reinforce the supporting effect of the thrust bearing 6, 6/1, 6/2, 6/3, the fixed frame 3 in the vicinity of the corner bearing 6, 6/1, 6/2, 6/3 filled with an additional material, eg. B. foamed with a correspondingly strong curing foam.
