Abstract

There is provided a pivot hinge for windows, doors or the like, especially a corner bearing for turn-and-tilt wings, which allows the pressure force for the wing to be regulated when the latter bears in the closed position against the frame. The pivot hinge 1 has a hinge part 3 possessing a pivot sleeve 6 and a hinge part 2 possessing a bearing bolt or bearing journal 5, the bearing bolt or bearing journal 5 of the hinge part 2 engaging into a bearing hole 7 of the pivot sleeve 6 of the hinge part 3. In the hinge part 3 possessing the pivot sleeve 6 is arranged a threaded member 13 which is adjustable transversely relative to its bearing hole 7 and via which the axial position of the bearing bolt or bearing journal 5 on the hinge part 3 possessing the pivot sleeve 6 can be adjusted in the transverse direction. The threaded member 13 sits rotatably, but axially non-displaceably in the hinge part 3 and is in engagement with a mating thread in an intermediate piece 17. The intermediate piece 17 on the one hand is held by the hinge part 3 so as to be pivotable to a limited extent and on the other hand engages on the bearing bolt or bearing journal 5 of the hinge part 2, in order to guarantee a relatively large-area and therefore sufficiently stable mounting for the bearing bolt or bearing journal 5. <IMAGE>

for windows, doors or similar«

The innovation relates to a hinge joint for windows, doors or the like, in particular a lower corner bearing for tilt and turn sashes, with a hinge part having a joint sleeve, e.g. a corner hinge on the door side, and a hinge part having a bearing pin or pivot, e.g. a corner bearing on the frame side, wherein the bearing pin or pivot of the second hinge part engages in a bearing hole of the joint sleeve of the first hinge part, and with a threaded member seated in the hinge part having the joint sleeve, adjustable transversely to the bearing hole, via which the axial position of the bearing pin or pivot on the hinge part having the joint sleeve can be adjusted in the transverse direction, primarily for regulating the pressure of the sash against the fixed frame.

Hinge joints of this type are already known - as adjustable corner bearings for tilt-and-turn windows or doors - as can be seen, for example, from DE-GM 79 25 975 or the corresponding EP-PS 0 025 879 or AT-PS 378 403.

While in the hinge joint according to DE-GM 79 25 975 or EP-PS 0 025 879 the threaded member is axially adjustable by rotation in the hinge part containing the joint sleeve and engages with a screwed-in circumferential groove for the purpose of adjustment on the circumference of the bearing pin or pin carried by the second hinge part, according to AT-PS 378

-2-

the threaded member is rotatably but axially immovably received by the hinge part having the joint sleeve and has a screw-like groove formed over part of its circumference, with which it directly engages the circumference of the bearing bolt or pin carried by the second hinge part.

In all known hinge joints, the threaded member is provided on at least one end face with a tool recess, for example a polygonal recess, which is accessible through a hole in the wall of the hinge part with a suitably profiled socket wrench, so that the threaded member can be rotated and the hinge joint can be adjusted via this.

A disadvantage of all known hinge joints is that there is always only a line contact between the threaded member of the first hinge part, which has the joint sleeve, and the bearing pin or journal of the second hinge part within the bearing hole of the joint sleeve, so that the bearing forces acting essentially transversely to the longitudinal axis of the bearing pin or journal can only be absorbed incompletely. The consequence of this is not only an unstable bearing connection between the two hinge parts of the hinge joint, but considerable signs of wear can also occur on the relatively small contact surfaces between the bearing pin or journal and the threaded member.

To avoid these disadvantages, i.e. to improve the bearing engagement between the bearing hole of the joint sleeve of the first hinge part and the bearing bolt or pin of the second hinge part and to minimize the signs of wear in practical use, the innovation proposes an adjustable hinge joint of the type mentioned at the beginning, which is mainly characterized by the fact that the threaded member is rotatable but axially immovable in one hinge part.

&bull; I I · · t I

and is engaged with a counter thread in an intermediate piece, whereby this intermediate piece is held by one hinge part in a limited pivoting manner

and on the other hand engages the bearing pin or journal of the other hinge part.

Not only the rotatable but axially immovable screw member is housed in the first hinge part, which has the joint sleeve, but also the intermediate piece is pivotably accommodated therein.

Preferably, the intermediate piece has a design which ensures that it at least partially surrounds the bearing pin or journal of the other hinge part at its periphery in a form-fitting manner over a larger length range, i.e. over a large area.

According to the innovation, it has also proven to be advantageous if the intermediate piece sits to the side of the bearing hole in the joint sleeve of the hinge part and has a molded-in recess on its side surface facing the bearing hole, which forms a partial circumference of the bearing hole, whereby the intermediate piece is received by the hinge part so as to be movable about a pivot axis extending both transversely to the longitudinal axis of the bearing hole and transversely to the longitudinal axis of the threaded joint.

As an intermediate piece, a lever can be used in an advantageous manner which is mounted at its upper end as a pendulum support and which, at least near its lower end, on its long side facing the bearing hole, has a recess adapted to the cross-section of the bearing bolt or pin.

A further development feature in accordance with the innovation is also seen in the fact that the intermediate piece is accommodated in a chamber of the hinge part which is laterally adjacent to the bearing hole of the joint sleeve and which is adjacent to its support and/or fastening base.

-it-

The upper end of the pendulum support or the lever can therefore engage from below into a pocket separated by a wall opposite the bearing hole of the joint sleeve.

Furthermore, according to the innovation, the intermediate piece has a cantilever arm extending in the longitudinal direction of the bearing hole, which is provided at its free end with cylindrical - or spherical - bearing surfaces aligned concentrically to the pivot axis for the intermediate piece, to which complementary cylindrical - or angular - counter-lap surfaces are assigned within the chamber of the hinge part.

The pocket end can preferably have a concave cylindrical or spherical surface, while the lever end is provided with a correspondingly convex cylindrical or spherical surface.

According to the innovation, it is also provided that the chamber receiving the intermediate piece also has an opening on the opening side of the bearing hole, that the intermediate piece can be inserted into the chamber through this opening, and that at least one boundary edge of the opening is adjoined by a nose or a similar projection which can be deformed into the opening cross-section of the chamber behind the inserted intermediate piece.

It has also proven to be useful if the lever forming the intermediate link has a stepped thickening in the axial direction of the threaded link in the engagement area of the threaded link, which is accommodated by adapted extensions of the chamber or pocket.

According to the innovation, the hinge part having the joint sleeve and also the intermediate piece that can be inserted into its chamber can advantageously consist of die-cast metal, in particular die-cast zinc or die-cast brass.

If the hinge part having the bearing pin or journal is designed as a tilt-turn hinge bearing with a corner bearing pin that is tiltably mounted about a horizontal axle pin, it can be advantageous if the axle pin has a thread with the help of which the corner bearing pin can be horizontally displaced to a limited extent relative to the corner bearing housing.

According to the innovation, a bearing cup can be guided in the bearing hole of the joint sleeve of one hinge part, non-rotatably but axially displaceably, against which the free end of the bearing bolt or pin of the other hinge part rests, whereby the bearing cup in turn has its abutment on a screw element which sits in a counter thread of the joint sleeve, coaxially adjustable to the bearing hole. The free end of the bearing bolt or pin can have a spherical bearing dome, while the bearing cup contains a correspondingly spherical bearing recess.

An example of the subject of the innovation is explained in detail below using the drawing. It shows

Line IV-IV in Fig. 2 and

Fig. 7 is a view in the direction of arrow VII-VII of Fig. 2.

The example of a hinge joint shown in the drawing for windows, doors or the like forms a lower corner bearing 1, as is usually used to create an effective articulated support connection between a tilt-and-turn sash and a frame. The frame-side hinge part of this corner bearing 1 is formed by a corner bearing block 2, while the sash-side hinge part is designed as a so-called corner hinge.

The corner bearing block 2 carries a corner bearing bolt 5 supported by a horizontal axle bolt *f so that it can tilt to a limited extent, whereby the axle bolt 4 is axially adjustable to a limited extent with the help of interlocking threads in the corner bearing block 2 so that the corner bearing bolt 5 can be adjusted horizontally to a corresponding extent in a form-fitting manner relative to the corner bearing block 2.

The wing-side corner hinge 3 has a joint sleeve 6 with a bearing hole 7 running in its longitudinal direction, into which the corner bearing bolt 5 of the corner bearing block 2 can be inserted from below, as shown in Figs. 1 and 2 as well as *f and 6.

Approximately in the middle length section of the joint sleeve 6 of the corner hinge 3 and essentially above the bearing hole 7 of the same, a bearing cup 8 made of wear-resistant material, e.g. plastic, is guided, which is rotatable, but limited axially displaceable, the upper end of which is supported by a screw member 9, which sits in an internal thread 10 of the joint sleeve 6 and can be rotated by a socket wrench inserted into the joint sleeve 6 from above and thus can be adjusted axially in a form-fitting manner.

-7-

The bearing pan 8 is provided with a spherical bearing recess 11 at the bottom, with which a correspondingly spherical bearing cup 12 of the corner bearing bolt 5 is in support connection. In this way, the weight of the sash is introduced into the frame with the help of the corner bearing 1 consisting of the corner hinge 3 and the corner bearing block 2.

By rotating the screw element 9 in the internal thread 10 of the joint sleeve 6 of the corner hinge 3, the position of the sash can be adjusted to a limited extent in the vertical direction relative to the frame.

In many cases, it is also necessary to regulate the pressure of the sash relative to the frame in windows and doors in order to ensure that the closed sash is well sealed against the frame while functioning properly. This pressure regulation is carried out in the area of the corner hinge 3 of the corner bearing 1 shown in the drawing, which engages with the corner bearing bolt 5 of the corner bearing block 2 on the frame side via the bearing hole 7 of its joint sleeve 6.

The device for pressure regulation provided in the corner band 3 has, on the one hand, a threaded member 13 which is rotatable but axially immovable in a partial area 14b of a chamber 14 which is formed laterally from the bearing hole 7 and open at the bottom into the corner band 3 having the joint sleeve 6. The threaded member 13 has a tool engagement 15 on at least one end face, for example in the form of a polygonal recess for a socket wrench, which is elongated through a hole 16 in the walls of the corner band 3 delimiting the chamber 14.

The threaded member 13 passes through an intermediate piece 17, which is received in its entirety by the chamber 14 in the corner band 3, as can be seen particularly from Fig. 1, 2, 3 and 5 of the drawing. The intermediate piece 17 is equipped with a counter thread 18 for the positive adjustment engagement of the threaded member 13, such that the rotation of the

-8th-

Threaded member 13 causes a relative axial adjustment of the same with respect to the intermediate piece 17. In this way, the intermediate piece 17 can be continuously displaced in a form-fitting manner within the chamber 1* of the corner band 3, as can be seen particularly clearly from Figs. 3 and 5 of the drawing.

As already mentioned, the intermediate piece 17 is located to the side of the bearing hole 7 of the joint sleeve 6 in the chamber 14 of the corner hinge 3. The twin piece 17 is accommodated in the chamber 11 in the manner of a so-called pendulum support, i.e. it forms a lever which has an upwardly directed cantilever arm 19 with which it sits in the chamber 14 so as to be pivotable to a limited extent about a pivot axis 20 extending both transversely to the longitudinal axis of the bearing hole 7 and transversely to the longitudinal axis of the threaded member 13. The cantilever arm 19 projects into the section 14a of the chamber 14 from below and interacts as a support bearing via a convex spherical or cylindrical surface 21 forming the lever end with a correspondingly concave spherical or cylindrical surface 22 at the upper end of the section 14a of the chamber 14.

The section 14a of the chamber 14 which accommodates the boom arm 19 of the intermediate piece 17 is separated from the bearing hole 7 of the joint sleeve 6 by a wall 23 for the purpose of better stiffening, which can be seen in Figs. 1 and 2 of the drawing.

In the area below the cantilever arm 19, the intermediate piece 17 has a projection 24 with a molded-in recess 25 on its side surface facing the bearing hole 7 of the joint sleeve 6, whereby this projection 24 with recess 25 extends through a passage area 26 located below the wall 23 into the joint sleeve 6 of the corner band 3. The projection 24 and recess 25 of the intermediate piece 17 delimit a partial circumference of the bearing hole 7 in the joint sleeve 6, as is illustrated by Fig. 7 of the drawing.

From Figs. 1f to 7 of the drawing it is clear that the bearing hole 7 in the joint sleeve 6 of the corner band 3 has a spatial shape in the direction of a plane parallel to the longitudinal axis of the threaded member 13, which widens from top to bottom in a funnel-like manner, over an angular range which is matched to the possible swivel angle of the intermediate piece 7 within the chamber 7. Over the swivel angle range of the intermediate piece 17, its projection 24 and recess 25 in the area of the lower end of the joint sleeve 6 can therefore be adjusted in a form-fitting manner when the threaded member 13 is in the correct position, so that with their help a corresponding positional alignment of the corner bearing bolt 5 is brought about within the bearing hole 7 of the joint sleeve 6. The angular displacement of the corner bearing bolt 5 in the joint sleeve 6 relative to the longitudinal axis of the bearing hole 7 takes place around the center of the interlocking spherical surfaces, which are determined by the bearing recess 11 of the bearing cup 8 and the bearing tip 12 of the corner bearing bolt 5.

In particular, Figs. 1 and 2 of the drawing show that the chamber 14 containing the intermediate piece IT is formed laterally next to the bearing hole 7 of the joint sleeve 6 in the support and/or fastening base 27 of the back band 3.

Since this support and/or fastening base 27 serves to maintain a certain axial distance of the joint sleeve 6 from the overlapping peripheral surface of the wing, there is sufficient space available here for the formation of the chamber 14 and the accommodation of the intermediate piece 17 with the threaded member 13, as is also illustrated by Fig. 3 and 5. It can be seen from Fig. 3 and 5 of the drawing that the lever forming the intermediate piece 17 has a stepped thickening 28 in the engagement area of the threaded member 13 compared to the cantilever arm 19, which is accommodated by adapted extensions 14b and 14c of the chamber 14. These measures not only ensure a high degree of dimensional stability of the intermediate piece 17 in the engagement area of the threaded member 13 and in the force application area of the corner bearing bolt

-10-

-10-

5, but also ensures precise guidance of the intermediate link 17 in every possible angular setting.

It should also be mentioned that the corner band 3 with the joint sleeve 6 and the intermediate piece accommodated in its chamber 14 can most easily be made of die-cast metal, in particular die-cast zinc or die-cast brass. The intermediate piece 17 only needs to be inserted into the chamber 14 of the corner band 3 parallel to the axis of the bearing hole 7 of the joint sleeve 6, after the threaded member 13 has been screwed into its internal thread 18 - approximately to the middle position. EL. A secure holding of the intermediate piece 17 in the chamber 14 against loss can be achieved in the simplest case by forming a nose or a similar projection 29 on at least one limiting edge of the lower opening of the chamber arm 14 in such a way that it can be deformed behind the inserted intermediate piece 17 into the opening cross-section of the chamber 14, as can be seen in Fig. 2. However, it would also be conceivable to provide a hole in the cantilever arm 19 of the intermediate piece 17 in alignment with the pivot axis 20 and to form a corresponding through hole in the support or fastening base 27 of the corner band 3 from the rear. By pressing a bolt into the aligned holes, the intermediate piece 17 could then also be secured to the corner band 3 in a loss-proof manner, without this impairing its pivoting mobility as a pendulum support.

Since the recess 25 formed in the lateral projection 24 of the intermediate member 17 extends over a relatively large portion, namely approximately half, of the total length of the intermediate member 17, a relatively large area of enclosure of the corner bearing pin 5 in the lower end region of the joint sleeve 6 is ensured and thus a permanently precise and secure alignment of the corner bearing pin 5 in the bearing bore 7 is maintained for every possible pressure setting.

Finally, it should be emphasized that the design explained above using a lower corner bearing 1 for tilt and turn sashes can be easily

can also be implemented in simple hinge joints for windows, doors or the like, provided that these are equipped with a hinge part having a joint sleeve on the one hand and a hinge part having a bearing pin or journal on the other hand , which can be brought into and out of engagement with one another in the axial direction by means of a plug-in connection.
