Abstract

Hinge mounts are used on a window or door between a frame capping (68) and a wing capping parallel to it; the frame bearing block of the hinge mounts has a flat base plate (21) which lies flush in a cavity (23) sunk into the visible face (22) of the frame and opening out onto the frame rebate-peripheral face (24). The shallow cavity (23), on its boundary edges facing away from the frame rebate-peripheral face (24), has a contour formed by several (at least two) mutually intersecting circular arcs (67) to which the boundary edges (26) of the base plate (21) have a complementary line.

Description

The invention has a window or door with hinge fittings between a frame spar and a wing spar, e.g. an upright frame spar and an upright wing spar, to the subject and relates in particular to a tilt and turn window or door with a corner bearing assembly assigned to a lower corner zone of the frame and sash and an upper corner zone of frame and sash bearing assembly assigned.

• bei dem bzw. der eine flache Grundplatte des Rahmenlagerbocks jedes Gelenkbeschlages bündig in einer in die innere Blendrahmen-Sichtfläche eingesenkten, kreisbogenförmig konturierten und zur Blendrahmenfalz-Umfangsfläche ausmündenden Vertiefung aufgenommen ist,
• bei dem bzw. der von der Grundplatte des Rahmenlagerbocks jedes Gelenkbeschlages mindestens ein Lagerauge od. dgl. zur Aufnahme und/oder Halterung eines Gelenkbolzens oder -zapfens über die innere Blendrahmen-Sichtfläche vorsteht,
• und bei dem in den Lageraugen od. dgl. des Rahmenlagerbocks um den Gelenkbolzen bzw. mittels des Gelenkzapfens ein Flügelscharnierteil beweglich gehalten bzw. abgestützt ist, das im Bereich der Grundplatte des Rahmenlagerbocks von der Rahmen-Sichtfläche aus in einen Freiraum - die sogenannte Falzluft - zwischen den Falzumfangsflächen von Blendrahmen am Flügel übergreift und dort unmittelbar oder mittelbar mit dem Flügel in einer tragenden Verbindung steht.

A window or door of this type is already known from DE-U-72 02 326,

• in which a flat base plate of the frame bracket of each hinge fitting is received flush in a recess, which is recessed into the inner window frame visible surface, is contoured in a circular shape and opens out to the frame rebate peripheral surface,
• in which at least one bearing eye or the like protrudes from the base plate of the frame bearing block of each hinge fitting or the like for receiving and / or holding a hinge pin or journal above the inner frame visible surface,
• and in which a wing hinge part is movably held or supported in the bearing eyes or the like of the frame bracket around the hinge pin or by means of the hinge pin, which in the area of the base plate of the frame bracket from the frame visible surface into a free space - the so-called rebate clearance - overlaps between the fold peripheral surfaces of the frame on the sash and there is directly or indirectly in a load-bearing connection with the sash.

The disadvantage of this known window is that another recess recessed into the frame material must connect to the recess of the flat base plate of the frame bearing block, which is contoured in the shape of an arc of a circle, perpendicular to the frame level and which also opens out into the frame rebate circumferential surface, so that it is possible for one the angle hinge part forming the wing hinge part can reach from the area in front of the window frame visible surface through the free space - the so-called rebate clearance - between the rebate peripheral surfaces of the window frame and wing towards the wing.

The further depression can be produced together or in one operation with the shallow depression for receiving the base plate, for example using a stepped milling cutter. However, due to their depth, which is determined by the width dimension of the angle rail, there is a considerable weakening of the window frame.

However, it is particularly disadvantageous that the stepped bore must be carried out in the corner zone area of the frame. This results in a considerable weakening of the corner connection (mortise and tenon) between the upright frame spar and the subsequent horizontal frame spar.

The invention is based, so a window or a door with the aforementioned training features the task Improve that only relatively shallow recesses on the inner window frame visible surface are required for the installation of the hinge fittings and at the same time there is no destabilizing intervention in the corner connection (mortise and tenon) between the upright window frame rail and the subsequent horizontal window frame rail in the area of the corner zones. At the same time, however, it should be ensured that the shallow recesses required for receiving the base plate of each frame bearing block can still be produced by simple drilling operations, but that no additional recesses for the penetration of the part in front of the frame visible part and part in the free space between the Rebate circumferential surfaces of the frame and sash hinged parts are required.

• die flache Vertiefung in der inneren Blendrahmen-Sichtfläche an ihren von der Blendrahmenfalz-Umfangsfläche abgewendeten Begrenzungskanten eine von mehreren - nämlich mindestens zwei - sich gegenseitig überschneidenden Kreisbögen bestimmte - wenigstens etwa 3-förmige - Kontur hat,
• die flachen Vertiefungen sämtlicher Gelenkbeschläge lediglich in die innere Blendrahmen-Sichtfläche ein und desselben, z.B. aufrechten Blendrahmenholms eingesenkt sind,
• die von der Blendrahmenfalz-Umfangsfläche wegführenden Randkanten der Grundplatte jedes Rahmenlagerbocks einen zu den Begrenzungskanten der Vertiefung komplementären - also ebenfalls wenigstens etwa 3-förmigen - Verlauf haben,
• und jedes Flügelscharnierteil als ein aus relativ dünnem, aber breitem Flachmaterial bestehender und mehrfach abgewinkelt gestalteter Formkörper ausgeführt ist, der mit einem zur Flügelebene parallelen Winkelsteg in einem zur Blendrahmenfalz-Umfangsfläche hin offenen Ausschnitt, vornehmlich einer flachen Mulde, der Grundplatte des Lagerbocks eingesenkt liegt, während ein über die innere Blendrahmen-Sichtfläche hochragender Winkelschenkel eine mit dem Gelenkbolzen oder -zapfen zusammenwirkende Gelenkhülse trägt und ein in den Freiraum der Falzluft eingreifender Winkelschenkel seine Verbindungsbasis zum Flügel bildet.

To achieve this aim, the invention therefore provides that

• the shallow depression in the inner window frame visible surface has at least one approximately 3-shaped contour at its boundary edges facing away from the window frame rebate peripheral surface, namely at least two circular arcs intersecting one another,
• the shallow recesses of all joint fittings are only sunk into the inner frame visible surface of one and the same, for example upright frame spar,
• the edge edges of the base plate of each frame bearing block leading away from the frame rebate circumferential surface have a course which is complementary to the boundary edges of the depression, that is to say also at least approximately 3-shaped,
• and each wing hinge part is designed as a shaped body consisting of a relatively thin but wide flat material and of multiple angled design, which has an angular web parallel to the wing plane in a cutout open towards the peripheral frame rebate surface, primarily a flat trough, the base plate of the bearing block is sunk in, while an angled leg protruding over the inner frame of the frame supports an articulated sleeve that interacts with the articulated bolt or pin, and an angled leg that engages in the clearance of the rebate air forms its connection base to the wing.

Individual sub-features of the combination of features according to the invention are known per se for windows or doors with non-generic hinge fittings (see, for example, DE-C3- 20 40 525, DE-C3- 27 13 011, DE-U 74 15 712, DE-U-75 12 877 , DE-U-79 01 616). With the design of the non-generic hinge fittings, however, the problem posed according to the invention on generic windows or doors with hinge fittings cannot be solved.

It is particularly advantageous according to the invention that the recesses receiving the flat base plates of the frame pedestals can still be made by simple drilling operations despite their relatively large surface area and can be attached either to loose frame spars or to already assembled frame frames to let. When using suitable multiple drilling heads and special drilling tools, it is even possible to insert the mutually overlapping recess sections even simultaneously or in a single operation.

It has proven particularly useful in practice if, according to a further development measure of the invention, the flat base plate of the frame bearing block in the region of its contour, which is averted from the outer frame rebate circumferential surface and determined by the mutually overlapping circular arcs - approximately 3-shaped - contour, projects beyond the inner outer frame visible surface is upstream, which has longitudinal boundary edges running parallel to the frame peripheral surface.

In an embodiment according to the invention, the cover web can be fixed in position or be fixable in position by a pin-hole connection on the base plate and can carry a bearing eye or the like of the frame bearing block at least on or near one of its ends, preferably projecting beyond the circular arc contour of the base plate. Here, the cover web with the bearing eye or the like can be manufactured as a stamped and bent molded part made of sheet metal, while an injection molded molded part made of plastic or a die cast molded part made of metal forms the base plate. But there is also the possibility that the cover web with the bearing eye or the like. Is a metal die-cast molded part, while an injection molded plastic part forms the base plate.

Finally, however, the cover web with the base plate can also be made of the same material, in particular as a die-cast molded part made of metal, and can carry a bearing eye or the like at least at or near one of its ends, preferably projecting beyond the circular arc contour of the base plate.

Countersunk through holes which serve as receptacles for fastening screws can be provided in the cover web carrying the bearing eyes or the like, at least some of these through holes having a cover position with corresponding recesses in the flat base plate.

• bei dem bzw. der ein Rahmenlagerbock wenigstens eines Gelenkbeschlags zur Halterung eines Gelenkzapfens über die innere Blendrahmen-Sichtfläche vorsteht,
• und bei dem bzw. der mittels des Gelenkzapfens ein Flügelscharnierteil beweglich abgestützt ist,
• wobei dieses Flügelscharnierteil eine mit dem Gelenkzapfen zusammenwirkende Gelenkhülse trägt, die ein eingesetztes Futterstück enthält, das vorzugsweise aus einem verschleißfesten Kunststoffmaterial besteht und drehgesichert, aber axial verschiebbar in der Gelenkhülse aufgenommen ist,
• wobei der Gelenkzapfen sich mit seinem oberen, kugeligen Ende in einer Kugelpfanne des Futterstücks abstützt,
• und wobei das Futterstück in der Gelenkhülse ein mittels eines durch ein Drehwerkzeug betätigbaren Schraubenbolzens einjustierbares Widerlager hat.

The invention is also applicable to a window or a door,

• in which a frame bracket stands at least one hinge fitting for holding a hinge pin over the inner frame visible surface,
• and in which a wing hinge part is movably supported by means of the hinge pin,
• wherein this wing hinge part carries a joint sleeve cooperating with the hinge pin, which contains an inserted chuck, which preferably consists of a wear-resistant plastic material and secured against rotation but axially displaceable in the joint sleeve,
• the pivot pin being supported by its upper, spherical end in a ball socket of the chuck,
• and wherein the chuck has an abutment which can be adjusted by means of a screw bolt which can be actuated by a turning tool.

Windows or doors with corner bearing units of this type are already known, as can be seen, for example, from DE-U-80 00 745.

For the screw bolt used to adjust the chuck, a thread must be cut into at least the upper end of the bore for receiving the pivot pin, so that the chuck can be varied in its support height relative to the joint sleeve by the axial displacement occurring when the screw bolt is turned. The manufacture of the wing hinge parts having the joint sleeve is therefore complex and expensive.

Another disadvantage of the known articulated fittings of the generic type is that the articulation pin engages directly in the bore of the articulation sleeve and therefore lubricants (grease) have to be introduced into the articulation sleeve for the purpose of reducing wear.

In addition to the fact that the introduction of lubricant requires a special operation, soiling in the installation area of the joint fittings can also be easily caused by escaping lubricants.

Recognizing these inadequacies, the invention also has the task of specifying hinge fittings for a window or a door, which not only have a simple construction of the adjustment means and can therefore be produced inexpensively, but also a Ensure permanent, flawless work even without using lubricant.

This object is achieved according to the invention in that an upwardly directed sleeve section of the chuck contains an internal thread into which the screw bolt engages.
that the free end, for example a head of the bolt, has its abutment at a stop which constricts its clear cross section at the upper end of the joint sleeve, and that a lower sleeve section of the chuck below the ball socket encompasses the longitudinal part of the joint pin protruding into the joint sleeve.

An advantage of this embodiment of a wing hinge part is that its joint sleeve does not require any reworking, because the internal thread for the engagement of the screw bolt in the sleeve section of the chuck can either be formed directly during injection molding thereof, or simply by screwing in the screw bolt provided with a suitable thread can be molded. At the same time, the introduction of lubricants into the other sleeve section of the chuck is unnecessary because this can be made from a low sliding or self-lubricating plastic material.

In the simplest case, the stop constricting the clear cross section of the joint sleeve can consist of a web which is formed by the material of the joint sleeve and which is bent inside. For this purpose, the wing hinge part can be made from a relatively thin but wide flat material, primarily sheet steel, with the joint sleeve being rolled on in one piece.

The invention further provides that the lower sleeve portion of the chuck carries a rotary locking nose protruding over its outer circumference, which in a longitudinal gap the rolled joint sleeve of the wing hinge part can be engaged.

Finally, the invention provides that the lower sleeve section of the chuck can be engaged over its outer circumference of the rolled-up joint sleeve of the wing hinge part.

1 to 4 of the drawing, the dash frame 11 and the wing 12 are indicated by dash-dotted lines of a window or a door 10. The right upper corner zone of frame 11 and sash 12 is shown in FIG. 1, while the lower right corner zone of frame 11 and sash 12 can be seen in FIG. 3.

The wing 12 is connected to the frame 11 in the area of the upper corner zone by a hinge fitting 13 (see FIG. 1), while in the area of the lower corner zone it is connected to the frame 11 by a hinge fitting 14 (see FIG. 3) .

The hinge fitting 13 on the upper corner zone is designed as a scissor-type bearing assembly of a tilt-and-turn window or a tilt-and-turn door, while the hinge fitting 14 in the region of the lower corner zone forms the corner bearing assembly of such a tilt-and-turn window or a tilt-and-turn door .

Both hinge fittings 13 and 14 have a common, in front of the inner frame visible surface 22, vertical hinge axis 15-15, about which the wing 12 can be opened relative to the frame 11 in the rotational position.

The hinge fitting 14 forming the corner bearing assembly unit on the lower corner zone of the window or door 10 is also provided with a horizontal hinge axis 16-16 equipped, around which the wing 12 can be brought into the tilt-open position relative to the frame 11. The end tilting position of the wing 12 is then limited by a stay scissors 17, which is in operative connection with the hinge fitting 13 on the upper corner zone of the window or the door (see FIG. 1). The operative connection of the stay scissors 17 on the one hand with the hinge fitting 13 serving as a scissor-bearing unit and on the other hand with the wing 12 is of such a type that it also assumes a load-bearing function for the wing 12 when it rotates about the vertical hinge axis 15-15 is opened.

The stay scissors 17 and the joint fitting 13 forming the associated scissor-bearing unit can be designed, for example, in accordance with DE-C-37 02 957 and EP-B-0 277 286, respectively.

In the case of windows and doors 10, the sash 12 of which is attached to the frame 11 only as a rotating sash, the stay scissors 17 can be omitted if, in this case, the wing hinge part of the hinge fitting 13 has a direct connection to an attack on the corner zone of the sash 12, e.g. has angular fastener.

Two structurally identical hinge fittings 13 with two wing-side fastening parts designed to be mirror images of one another can also be used for the construction of windows 10 with tilting or folding sashes. In this case, however, the hinge fittings 13 are not attached between an upright frame spar and an upright wing spar, but between a horizontal frame spar and a horizontal wing spar.

The articulated fitting 13 assigned to an upper corner zone of the frame 11 and sash 12 in FIGS. 1 and 2, for example as a scissor-type bearing assembly, has a frame bracket 18 and one movable therein by means of an articulated pin 19 held wing hinge part 20. The frame bracket 18 is equipped with a flat base plate 21, which is received flush by a recess 23 recessed into the inner frame visible surface 22, which opens out towards the frame rebate circumferential surface 24.

On the base plate 21 there is a cover web 25 projecting beyond the inner window frame visible surface 22, which extends above and beyond the edge contour 26 of the base plate 21 and also at least slightly beyond the side facing away from the frame frame peripheral surface 24. This cover web 25 carries near its upper and lower ends a bearing eye 27 or the like protruding from the window frame visible surface 22 for the hinge part 20 holding the hinge part 20 above or below each bearing eye 27 or the like and also between the two bearing eyes 27 or the like. The cover web 25 is each equipped with countersunk through holes 28, which serve as receptacles for fastening screws. At least individual countersunk through holes 28 have a cover position with recesses 29 in the base plate 21, which can be seen particularly clearly in FIG. 6 of the drawing.

The wing hinge part 20 of the hinge fitting 13 is designed as a molded body made of relatively thin but wide flat material, for example made of sheet metal by means of stamping bending, with multiple angled shapes (cf. in particular FIG. 2 of the drawing). This molded body lies with an angular web 30 parallel to the main plane of the wing 12 in a cutout which is open towards the frame rebate peripheral surface 24, namely preferably a shallow depression 31 of the base plate 21, as is particularly clearly shown in FIG. 2 of the drawing. The shape and position of the trough 31 in the base plate 21, however, can be seen from FIGS. 6 and 7 of the drawing.

The angular web 30 of the wing hinge part 20 can be seen in the shallow depression 31 of the base plate 21 in such a way that, with the window or door 10 closed, in the direction parallel to the main plane of the frame 11 from the so-called overlap 32 of the wing 12 over most of its width without further can be attacked.

An angle leg 33 of the wing hinge part 20, which protrudes from the angular web 30 over the inner window frame visible surface 22, carries an articulated sleeve 34 which interacts with the hinge pin 19. One from the angular web 30 into the free space 35, the so-called rebate air, between the window frame rebate circumferential surface 24 and this parallel wing rebate circumferential surface 36 engaging angle leg 37 forms the connection base of the wing hinge part 20 to the wing 12. In the case of the articulated fitting 13 designed as a scissor-type bearing unit according to FIGS. 1 and 2 of the drawing, the angle leg 37 of the wing hinge part 20 is in the necessary holding connection via the stay scissors 17 with the wing 12.

3 and 4 of the drawing designed as a corner bearing assembly 14 also has a frame bracket 38 on which a wing hinge part 40 is supported via a hinge pin 39.

The base plate 41 of the frame bracket 38 is identical to the base plate 21 of the frame bracket 18 and arranged. It is thus arranged so that it is flush-sunk into a recess 23 on the outer frame visible surface 22 which opens out towards the outer frame rebate peripheral surface 24, as can be clearly seen in FIG. 4.

3 and 4 also has a cover web 45 which is carried by the base plate 41 and projects beyond the window frame visible surface 22. This is designed and has such an arrangement that it leads the edge contour 26 leading away from the window frame rebate peripheral surface 24 of the base plate 41 protrudes both upwards and downwards and at least slightly towards the side facing away from the frame rebate peripheral surface 24. In this case, the cover web 45 of the frame bracket 38 bears two bearing eyes 47 or the like only at its lower end at a distance from one another and aligned parallel to one another in vertical planes, of which a horizontal support bolt is held in alignment with the horizontal hinge axis 16-16. The support bolt 46 sits in a known manner in the direction of its longitudinal axis in a screw-adjustable manner in the threads of the bearing eyes 47 of the frame bearing bracket 38. It has a circumferential groove 42 in the area between the two bearing eyes 47 or the like, in which the lower end of a pivot pin 39 via a molded fork piece 43 about the horizontal hinge axis 16-16 - as a pivot pin - is supported in a tilting manner. By screwing the support bolt 46 in the bearing eyes 47 or the like. The frame bearing bracket 38, the pivot pin 39 can be displaced to a limited extent parallel to the main plane of the frame 11 between the two bearing eyes 47 or the like.

In a manner corresponding to the frame bracket 18 of the joint fitting 13, the cover web 45 of the frame bracket 38 also has countersunk through holes 48 serving as receptacles for fastening screws, which have cover positions 41 with recesses 49 in the base plate.

The wing hinge part 40 of the joint fitting 14, which is designed, for example, as a corner bearing structural unit, is received with an angled web 50, which extends parallel to the main plane of the wing 12, with a flat recess 51 in the base plate 41 of the frame bearing bracket 38 in the rear contact with the flap 32 of the wing 12 (see Fig. 4). This in exactly the same way as the angular web 30 of the wing hinge part 20 on the joint fitting 13 according to FIGS. 1 and 2.

In the wing hinge part 40 according to FIGS. 3 and 4, the angled web 50 is adjoined in one piece by an angled leg 53 which rises above the inner window frame visible surface 22 by means of an interposed cranking section 52, from which in turn an articulated sleeve 54 extends, which can be plugged onto the articulated pin 39 .

On the other hand, an angle leg 57 protrudes from the angular web 50 of the wing hinge part 40, which protrudes into the free space 35, the so-called rebate air, between the frame rebate peripheral surface 24 and the wing rebate peripheral surface 36. This angle leg 57 forms the connection base for the wing hinge part 40 to the wing 12. For this purpose, it is equipped with an upward extension section 55 and a horizontally bent support bracket 56 in order to enable proper attachment to the corner zone of the wing 12.

The joint fitting 14, which is designed, for example, as a corner bearing structural unit, has an inserted lining piece 58 in its joint sleeve 54, which preferably consists of a wear-resistant plastic material and is received in the joint sleeve 54 in a rotationally secured but axially displaceable manner. The pivot pin 39 engages in a lower sleeve section 59 of the chuck 58 and is supported with its upper, spherical end 60 in a ball socket 61 of the chuck 58. An upwardly directed sleeve section 62 of the chuck 58 contains an internal thread 63 in which a screw bolt 64 is seated. Its head 65 finds its abutment on a stop web 66 which constricts the clear cross section of the joint sleeve 54 at the upper end. With the aid of a turning tool which can be engaged in an engagement of the head 65, the axial position of the screw bolt 64 in the internal thread 63 of the chuck 58 can be changed in order to thereby continuously adjust the height of the joint sleeve 54 relative to the chuck 58.

• A flat base plate 21 or 41 of the frame bearing bracket 18 or 38 of each joint fitting 13 or 14 is received flush in a recess 23 which is recessed into the inner window frame visible surface 22 and is contoured in the shape of a circular arc and opens out to the frame rebate peripheral surface 24.
• At least one bearing eye 27 or 47 or the like stands from the base plate 21 or 41 of the frame bracket 18 or 38 of each joint fitting 13 or 14 for receiving and / or holding a joint bolt 19 or joint pin 39 via the inner frame visible surface 22 in front.
• A wing hinge part 20 or 40 is movably held or supported in the bearing eyes 27 or 47 or the like of the frame bracket 18 or 38 around the joint pin 19 or pivot pin 39, which in the area of the base plate 21 or 41 of the frame bracket 18 or 38 overlaps from the outer frame visible surface 22 into a free space 35 - the so-called rebate air - between the outer frame rebate circumferential surface 24 and the sash rebate circumferential surface 36 and is there directly or indirectly in a load-bearing connection with the wing 12.

• Die flache Vertiefung 23 in der inneren Blendrahmen-Sichtfläche 22 hat, wie besonders deutlich aus Fig. 5 der Zeichnung zu entnehmen ist, an ihren von der Blendrahmenfalz-Umfangsfläche 24 abgewendeten Begrenzungskanten eine von mehreren, nämlich mindestens zwei, sich gegenseitig überschneidenden Kreisbögen 67 bestimmte Kontur. D.h., die flache Vertiefung 23 weist zumindest einen etwa 3-förmigen Grundriß auf.
• Die flachen Vertiefungen 23 zur Aufnahme der Grundplatten 21 bzw. 41 sämtlicher Gelenkbeschläge 13 und 14 sind lediglich in die innere Blendrahmen-Sichtfläche 22 ein und desselben, beispielsweise eines aufrechten Blendrahmenholms 68 eingesenkt, so daß der hieran in einer Eckzone anschließende, z.B. waagerechte Blendrahmenholm 69 von derartigen Vertiefungen 23 völlig frei bleibt.
• Die von der Blendrahmenfalz-Umfangsfläche 24 wegführenden Randkanten 26 der Grundplatte 21 bzw. 41 jedes Rahmenlagerbocks 18 bzw. 38 haben einen zu den Begrenzungskanten (Kreisbögen 67) der Vertiefung 23 komplementären Verlauf (vergl.

The following precautions are of particular importance because the overall structure of the windows or doors 10 can thereby be optimized.

• As can be seen particularly clearly from FIG. 5 of the drawing, the shallow depression 23 in the inner window frame visible surface 22 has one of several, namely at least two, mutually overlapping arcs 67 defined on its boundary edges facing away from the window frame rebate peripheral surface 24 Contour. That is, the flat recess 23 has at least an approximately 3-shaped plan.
• The shallow recesses 23 for receiving the base plates 21 and 41 of all the joint fittings 13 and 14 are only sunk into the inner frame visible surface 22, for example an upright frame spar 68, so that the frame frame 69, for example horizontal frame frame 69, adjoins it in a corner zone of such depressions 23 remains completely free.
• The edge edges 26 of the base plate 21 or 41 of each frame bearing block 18 or 38 leading away from the frame rebate peripheral surface 24 have a course which is complementary to the boundary edges (circular arcs 67) of the depression 23 (cf. FIG. 6 of the drawing). So you are also guided with an at least approximately 3-shaped course.
• Each wing hinge part 20 or 40 is designed as a shaped body consisting of relatively thin but wide flat material and of multiple angled design, which has an angular web 30 or 50 parallel to the wing plane in a cutout which is open towards the frame rebate peripheral surface 24, namely a flat depression 31 or 51 lies, while an angle leg 33 or 53 projecting above the inner frame visible surface 22 carries an articulated sleeve 34 or 54 which interacts with the hinge pin 19 or hinge pin 39 and an angle leg 37 or 57 which engages in the free space 35 of the rebate air the Connection base of the wing hinge part 20 or 40 to the wing 12 forms.
• The cover web 25 or 45, which is assigned to the flat base plate 21 or 41 of each frame bearing block 18 or 38 in the region of its area of the frame rebate peripheral surface 24 and projects beyond the inner window frame visible surface 22, has at least one side facing away from the frame rebate peripheral surface 24 to this parallel longitudinal boundary edge 70, which covers at least the contour of the arcs 67 of each flat recess 23 in front of the inner frame visible surface 22.

It should be mentioned at this point that the shallow recesses 23 can be worked into the inner frame visible surface 22 with the help of so-called drill cutters or Forstner drills. It is possible to use either one and the same tool in two successive work steps one after the other with a center distance 71, as is shown in FIG. 5. However, it is also possible to use a double boring head with a fixed center distance 71, which is equipped with boring cutters which, despite overlapping rotating circles, do not interfere with one another while rotating.

Deviating from the exemplary embodiments shown in the drawing, there is of course also the possibility of determining, for example, three mutually overlapping circular arcs 67 in the recesses 23 made in the inner window frame visible surface 22 and in the base plates 21 and 41 of the frame bearing blocks 18 and 38 accommodated thereby To give edge contour. In this case, it would then be possible to work with a commercially available triple drill head and three drill cutters with a smaller nominal diameter which are driven by it at the same time.

There is the possibility, on the one hand, of producing the base plates 21 or 41 and, on the other hand, the cover webs 25 or 45 with their bearing eyes 27 or 47 or the like, separately from one another. Then the cover web 25 or 45 can be fixed to the base plate 21 or 41 by a pin / hole connection 72/73. 6 and 7 of the drawing, two upstanding pins 72 are provided for this purpose, for example on the top of the base plate 21, which have a rectangular outline. These pins 72 can be inserted into correspondingly designed openings 73 in the cover webs 25 and 45 of the frame bearing blocks 18 and 38, as can be seen in FIGS. 1 and 3 of the drawing.

But it can also protrude from the back of the cover webs 25 or 45 pins, which can then be positively inserted into matching holes in the base plate 21 or 41.

Due to this configuration, it is possible, for example, in the articulated fitting 13 according to FIGS. 1 and 2, to produce the cover web 25 with the bearing eyes 27 or the like as a metal die-cast molded part, while an injection-molded plastic part can be used as the base plate 21 .

On the other hand, it can be seen from the joint fitting 14 according to FIGS. 3 and 4 that the cover web 45 with its bearing eyes 47 or the like can also be manufactured as a stamped and bent molded part made of sheet metal, while an injection molded molded part made of plastic or a die-cast metal part forms the base plate 41.

However, there is also the possibility of designing the cover web 25 or 45 with the base plate 21 or 41 in the same material, in particular as a die-cast metal part.

In this case in particular, it is advisable, in addition to the countersunk through holes 28 to 48 and the recesses 29 to 49 for fastening screws penetrating into the material of the frame 11, which are normal to the plane of the frame, and only provide additional countersunk through holes in the base plate 21 or 41. Whose axis should receive such an inclined position to the plane of the base plate 21 or 41 that the fastening screws penetrate into the material with a position inclined towards the plane of the frame 11.

The wing hinge part 40 according to FIGS. 3 and 4 is designed as a multi-angled, e.g. Shaped body made by stamping and bending made of sheet metal, which lies with an angular web 50 parallel to the sash plane in a cutout open to the frame rebate circumferential surface 24, namely a shallow depression 51, while an angled leg 53 protruding over the inner frame visible surface 22 has the same shape the support pin 39 cooperating joint sleeve 54 carries and an angle leg 57 engaging in the free space 35 of the rebate air forms the connection base of the wing hinge part 40 to the wing 12. The joint sleeve 54 is rolled onto the molded body in one piece. This leaves a radial gap 44 at the engagement end for the support pin 39, into which a radial lug 73 engages at the lower end of the sleeve section 62, which acts as an anti-rotation device for the chuck 58.

In the injection molding of the lining piece 58 made of plastic, the screw bolt 64 can be used directly as a mandrel to form the internal thread 63 and can be inserted into the injection mold for this purpose. After demolding the chuck 58, the screw bolt can then be partially unscrewed, for example by approximately 4 to 5 millimeters, from the finished internal thread 63 in order to clear the desired adjustment path for the screw bolt 64 supported by its head 65 on the stop web 66.
