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>

Description

The invention relates to a hinge joint for windows, doors or the like, in particular a lower corner bearing for turn-tilt sash, with a hinge part having a joint sleeve, e.g. a wing-side corner hinge, and a hinge part having a bearing pin or pin, for example a frame-side corner bearing block, the bearing pin or pin of the second hinge part engaging in a bearing hole of the joint sleeve of the first hinge part, and with a seated in the hinge part having the joint sleeve transverse to Bearing hole-directed threaded member, which is rotatably but axially immovable in the first hinge part and via which the axial position of the bearing pin or journal on the hinge part having the hinge part can be adjusted in the transverse direction primarily for regulating the pressure of the wing against the fixed frame.

A hinge joint of this type is already known from AT-B 378 403 as an adjustable corner bearing for turn and tilt sashes of windows or doors. Here, the rotatable but axially non-displaceable thread member received by the hinge part having the hinge part has a screw-shaped groove formed over part of its circumference, with which it engages directly on the circumference of the bearing pin or journal carried by the second hinge part.

According to DE-U 79 25 975 or EP-B 0 025 879, however, a hinge joint serving as an adjustable corner bearing for tilt-and-turn sashes of windows or doors is already known, in which the threaded member is axially adjustable by rotation in the hinge part having the joint sleeve and via a screwed-in circumferential groove for the purpose of adjustment on the circumference of the bearing pin or journal carried by the second hinge part.

In each of these known hinge joints, the threaded member is provided on at least one end face with a tool engagement, for example a polygonal recess, which is accessible through a hole in the wall of the hinge part with an adapted-profiled socket wrench, so that rotation of the threaded member and via this one Pressure adjustment of the hinge joint can be made.

A disadvantage of these known hinge joints, however, is that in each case there is only a line contact between the threaded member of the first hinge part having the joint sleeve and the bearing pin or journal of the second hinge part within the bearing hole of the joint sleeve. The bearing forces acting essentially transversely to the longitudinal axis of the bearing pin or journal can thus only be absorbed incompletely. The result of this is not only an unstable bearing connection between the two hinge parts of the hinge joint, but also considerable wear and tear on the relatively small contact surfaces between the bearing pin or journal and the threaded member can occur.

A corner bearing for windows or doors which these disadvantages are not peculiar belongs to the state of the art, through CH-A 651 101. It consists of a base plate to be attached to the frame and a bearing block made of die-cast, between the flanges of which are provided with a thread A pivot pin is pivotally and axially adjustable mounted, and an adjusting bolt which is rotatably but axially immovably fixed in the base plate, the threaded part of which passes through a threaded hole in the bearing block and is formed from at least one support pin which extends through the base plate and is integrally formed on the lower end of the bearing block and with at least one Nose engages behind the base plate.

A disadvantage of this corner bearing, however, is that the threaded hole provided in the bearing block for the engagement of the threaded member rotatably but axially immovably on the base plate must be provided below the support for the pivot pin.
The bearing bracket supporting the pivot pin therefore requires a correspondingly large overall length for the correspondingly large installation space - the so-called frame frame clearance - required in the lower area of the window, the door or the like on the frame, but this is not always available.

For a hinge joint of the type specified at the outset, in order to improve the bearing engagement between the bearing hole of the joint sleeve of the first hinge part and the bearing pin or journal of the second hinge part and to minimize the signs of wear in practical use, an embodiment is proposed which is mainly characterized by
that the threaded member is in engagement with a mating thread in an intermediate piece,
that this intermediate piece sits laterally from the bearing hole in the hinge part of the hinge part and has a molded-in trough on its side surface facing the bearing hole, which forms a partial circumference of the bearing hole,
and that this intermediate piece, as a pendulum support, engages in a support bearing of the hinge part with a cantilever arm which has a pivot axis which extends both transversely to the longitudinal axis of the bearing hole and transversely to the longitudinal axis of the threaded member.

According to the invention, not only the rotatable but axially immovable threaded member, but also the intermediate piece is accommodated in the first hinge part having the joint sleeve. The design of the intermediate piece ensures that the bearing pin or journal of the other hinge part is at least partially positively encompassed over its circumference over a larger length range, that is to say over a large area.

It has also proven itself according to the invention if the support bearing for the intermediate piece is formed on the one hand by a convex spherical or cylindrical surface and on the other hand by a concave spherical or cylindrical surface, the common pivot axis of which extends both transversely to the longitudinal axis of the bearing hole and transversely to the longitudinal axis of the threaded member extends.

A further development feature according to the invention is further seen in that the intermediate piece is accommodated in a chamber of the hinge part which adjoins the bearing hole of the joint sleeve and which is adjacent to its support and / or fastening base.

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

It is further provided according to the invention that 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 also spherical - bearing surfaces oriented concentrically to the pivot axis for the intermediate piece, the complementary cylindrical - or spherical - counter bearing surfaces are assigned within the chamber of the hinge part.

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

It is also provided according to the invention that the chamber receiving the intermediate piece also has an opening towards the opening side of the bearing hole, that the intermediate piece can be inserted into the chamber through this opening, and that a nose or a similar projection is adjacent to at least one boundary edge of the opening which is deformable behind the inserted intermediate piece in the opening cross-section of the chamber.

It has also proven useful if the lever forming the intermediate member has a thickening in the engagement region of the threaded member which is graduated in the axial direction and is accommodated by adapted extensions of the chamber or pocket.

According to the invention, the hinge part which has the joint sleeve and also the intermediate piece which can be used in 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 pivot is designed as a tilt and turn corner bearing with a corner bearing pin tiltably mounted about a horizontal axle pin, it can be advantageous if the axle pin has a thread by means of which the corner bearing pin can be displaced horizontally to a limited extent relative to the corner bearing housing .

According to the invention, in the bearing hole of the hinge part of the one hinge part, in addition to the support bearing for the intermediate piece, a bearing socket can also be rotatably but axially displaceably, against which the free end of the bearing pin or journal of the other hinge part is supported, the bearing socket again supporting its abutment has a screw member, which is adjustable in a counter thread of the threaded sleeve coaxial to the bearing hole. The free end of the bearing pin or journal can have a spherical bearing cap, while the bearing cup contains a correspondingly spherical bearing recess.

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

The corner bracket 2 carries a corner bearing pin 5 supported to a limited extent by a horizontal axle pin 4, the axle pin 4 being axially adjustable to a limited extent by means of interlocking threads in the corner bracket 2, so that the corner bearing pin 5 can be horizontally adjusted to a corresponding degree relative to the corner bracket 2.

The wing-side corner hinge 3 has an articulated sleeve 6 with a bearing hole 7 running in the longitudinal direction thereof, into which the corner bearing pin 5 of the corner bearing block 2 can be inserted from below, as shown in FIGS. 1 and 2 as well as 4 and 6.

Approximately in the middle length section of the hinge sleeve 6 of the corner hinge 3 and essentially above the bearing hole 7 thereof, it cannot be rotated, but is axially displaceable to a limited extent a bearing socket 8 made of wear-resistant material, for example plastic, the upper end of which is supported by a screw member 9, which is in a Internal thread 10 of the joint sleeve 6 is seated and rotated by a socket wrench inserted into the joint sleeve 6 from above and can thus be adjusted axially with a positive fit.

The bearing pan 8 is provided at the bottom with a spherical bearing trough 11 with which a corresponding spherical bearing cap 12 of the corner bearing bolt 5 comes into support connection. In this way, the weight of the wing is introduced into the frame using the corner bearing 1 consisting of the corner hinge 3 and the corner bracket 2.

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

In the case of windows and doors, it is also often necessary to regulate the pressure of the sash relative to the frame in order to ensure that the closed sash is well sealed against the frame when it functions properly. This pressure regulation is carried out in the corner bearing 1 shown in the drawing in the region of the corner hinge 3, which is in engagement with the corner bearing pin 5 of the frame-side corner bearing block 2 via the bearing hole 7 of its joint sleeve 6.

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

The threaded member 13 passes through an intermediate piece 17, which is received by the chamber 14 in the corner hinge 3, as can be seen particularly in FIGS. 1, 2 and 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 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 shifted continuously and positively within the chamber 14 of the corner hinge 3, as can be seen particularly clearly from FIGS. 3 and 5 of the drawing.

As already mentioned, the intermediate piece 17 sits laterally from the bearing hole 7 of the joint sleeve 6 in the chamber 14 of the corner hinge 3. The intermediate piece 17 is accommodated in the chamber 14 in the manner of a so-called pendulum support, ie it forms a lever which moves one upwards has directed cantilever arm 19 with which it is pivotably movable in the chamber 14 about a pivot axis 20 which extends 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 acts 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 as a support bearing together.

The section 14a of the chamber 14 which receives the cantilever arm 19 of the intermediate piece 17 is separated for the purpose of better stiffening against the bearing hole 7 of the joint sleeve 6 by a wall 23 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 on its side surface facing the bearing hole 7 of the joint sleeve 6 a projection 24 with a molded-in trough 25, this projection 24 with trough 25 passing through a passage area 26 in under the wall 23 extends the joint sleeve 6 of the corner hinge 3. Projection 24 and trough 25 of the intermediate piece 17 limit a partial circumference of the bearing hole 7 in the joint sleeve 6, as is illustrated by FIG. 7 of the drawing.

4 to 7 of the drawing it is clear that the bearing hole 7 in the hinge sleeve 6 of the corner hinge 3 has a spatial shape in the direction of a plane parallel to the longitudinal axis of the threaded member 13, which widens like a funnel from top to bottom, namely over a Angular range, which is matched to the possible pivot angle of the intermediate piece 7 within the chamber 7. Over the swivel angle range of the intermediate piece 17, its projection 24 and trough 25 can therefore be positively adjusted in the region of the lower end of the joint sleeve 6 when the threaded member 13 is rotated in such a way that with its help a corresponding positional orientation of the corner bearing pin 5 within the bearing hole 7 of the joint sleeve 6 is brought about. The angular displacement of the corner bearing pin 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 socket 8 and the bearing cap 12 of the corner bearing pin 5.

1 and 2 of the drawing in particular show that the chamber 14 containing the intermediate piece 17 is formed laterally next to the bearing hole 7 of the joint sleeve 6 in the support and / or fastening base 27 of the corner hinge 3.

Since this support and / or fastening base 27 serves to maintain a certain center distance of the joint sleeve 6 from the rollover circumferential surface of the wing, there is a sufficiently large space for the molding of the chamber 14 and the accommodation of the intermediate piece 17 with the threaded member 13 , as is also illustrated by FIGS. 3 and 5. 3 and 5 of the drawing can be seen that the lever forming the intermediate member 17 in the engagement area of the threaded member 13 has a thickened portion 28 which is graduated relative to the extension arm 19 and which is accommodated by adapted extensions 14b and 14c of the chamber 14. These measures not only ensure a high dimensional stability of the intermediate member 17 in the engagement area of the threaded member 13 and in the force application area of the corner bearing bolt 5 guaranteed, but also get an exact guidance of the intermediate member 17 at every possible angle setting position.

It should also be mentioned that the corner band 3 having the joint sleeve 6 and also the intermediate piece accommodated in its chamber 14 can be produced most easily from die-cast metal, in particular die-cast zinc or die-cast brass. The intermediate piece 17 need only be inserted axially parallel to the bearing hole 7 of the joint sleeve 6 into the chamber 14 of the corner hinge 3 after the threaded member 13 has been screwed into its internal thread 18, for example in the middle position. A loss-proof mounting of the intermediate piece 17 in the chamber 14 can be achieved in the simplest case in that a nose or a similar projection 29 is formed on at least one boundary edge of the lower opening of the chamber 14 so that he or she is inserted behind the Intermediate piece 17 can be deformed 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 hinge 3 from the rear. By pressing a bolt into the holes aligned with one another, the intermediate piece 17 could then also be fixed in a loss-proof manner on the corner hinge 3, without thereby affecting its pivoting mobility as a pendulum support.

Since the trough 25 formed in the lateral extension 24 of the intermediate member 17 extends over a relatively large proportion, namely approximately half, of the total length of the intermediate piece 17, a relatively large-area encirclement of the corner bearing pin 5 in the lower end region of the joint sleeve 6 is ensured and thus one Get permanently exact and safe alignment of the corner bearing pin 5 in the bearing bore 7 with every possible pressure setting.

Finally, it should be emphasized that the configuration explained above with reference to a lower corner bearing 1 for tilt-and-turn sashes is straightforward can also be realized with simple hinge joints for windows, doors or the like, provided that these are equipped on the one hand with a hinge part having an articulated sleeve and on the other hand with a hinge part having a bearing pin or journal which can be brought into and out of engagement with one another in the axial direction by a plug connection to let.
