Description

The present invention relates to a corner bearing for a window, a door or the like with a base plate which is designed for fastening in a corner of a frame of the window, door or the like formed by converging C-shaped profile elements, and a coupling device connected to the base plate , which can be coupled to a wing of the window, door or the like in order to store it movably on the frame.

Such corner bearings generally form components of pivot fittings, tilt fittings or tilt and turn fittings. Depending on the design, corner bearings can be provided for attachment in a lower corner or in an upper corner of the frame. Corner bearings are often concealed, which means they are arranged completely between the frame and the sash frame. In order to avoid a collision between the frame and the sash when the sash is opened by rotation despite the internal arrangement of the corner bearing, the coupling device can be designed in such a way that the sash performs a parking movement transversely to the plane of the frame when opening. For this purpose, the coupling device can in particular comprise an extension arm and a control arm, which are coupled to one another to form an X-scissor. The coupling device can also include a scissor arm of a tilt-and-turn fitting or can be designed to be coupled to such a scissor arm. In this respect, a corner bearing of the type mentioned at the beginning can also form a scissor bearing.

The EP 3 480 398 A1 discloses a corner bearing according to the preamble of claim 1.

In the EP 3 190 252 A1 a corner bearing with a mounting bracket is disclosed, which is connected to two arms of a scissor bearing.

Reliable attachment of the base plate to the frame is of great importance, especially due to increasingly high sash weights. In principle, the base plate can be screwed onto the frame. Alternatively, the base plate can be aligned obliquely to the frame plane using Grub screws are clamped to one of the C-shaped profile elements. However, there is the problem that screws screwed into the profile elements often lead to signs of corrosion, since the screws are usually designed as steel screws and the profile elements as aluminum parts. In addition, the different components have different thermal expansion coefficients due to the different materials, so that the corner bearing can loosen due to differences in tension when exposed to appropriate heat or cold.

It is an object of the present invention to design a corner bearing of the type mentioned in such a way that a reliable attachment of the base plate to the frame is possible without the risk of corrosion forming or loosening of the corner bearing.

This problem is solved by a corner bearing with the features of claim 1.

A corner bearing according to the invention comprises a clamping angle with a first clamping leg extending in a first longitudinal direction for fastening the base plate to a horizontal C-shaped profile element of the frame and a second clamping leg which is angled relative to the first clamping leg and extends in a second longitudinal direction for fastening the base plate on a vertical C-shaped profile element of the frame, the first clamping leg of the clamping angle being arranged on a rear side of the base plate facing away from the coupling device and rotatably mounted about an axis of rotation between an insertion position and a clamping position, the first clamping leg being inserted into a groove in the insertion position horizontal C-shaped profile element can be used and in the clamping position the first clamping leg engages behind webs of the horizontal C-shaped profile element, and the first clamping leg moves in the direction by means of an adjusting device the axis of rotation can be pulled towards the base plate in order to fix the base plate on the frame in a clamping manner in the clamping position of the first clamping leg.

The elongated clamping legs of the clamping angle allow a larger area of clamping or support than is possible, for example, with individual clamping plates, clamping blocks or clamping disks that clamp more at certain points. Due to the two clamping legs that are at an angle to one another, the base plate can be fixed or at least supported on both the horizontal profile element and the vertical profile element.

When the first clamping leg is in the insertion position, it can be aligned parallel to the longitudinal extent of the groove and inserted into it without the hassle of threading. A subsequent rotation of the first clamping leg into the clamping position causes sections of the first clamping leg located on both sides of the axis of rotation to swing out in opposite directions, so that each of the two opposite webs of the horizontal C-shaped profile element is gripped behind by one of these sections. In this way, the first clamping leg can spread laterally into the profile groove. This ensures a particularly secure attachment of the base plate to the profile. The first clamping leg located in the clamping position can be pulled onto the base plate by actuating the adjusting device in order to clamp the webs between the first clamping leg and the base plate and thus fasten the base plate to the horizontal profile element.

When the first clamping leg is rotated, the second clamping leg is rotated from the insertion position into the clamping position and reaches a support position in which it engages behind a web of the vertical profile element over its entire length. In the support position, the second clamping leg can be viewed in cross section relative to the side inner walls and/or the rear The inner wall of the profile groove must be tilted and thus be supported in the profile groove or spread into it.

It is preferred that the axis of rotation runs transversely, in particular at right angles, to the back of the base plate. The first clamping leg can thus spread laterally into the horizontal C-shaped profile element when the back of the base plate is placed against the top or bottom of the horizontal profile element.

Preferably, the first clamping leg is mounted on the base plate by means of a pivot bearing defining the axis of rotation. The pivot bearing can be designed to allow a displacement of the clamping angle relative to the base plate along the axis of rotation at least in some areas, so that the first clamping leg can be axially adjusted for clamping. The area within which displacement is permitted can be defined by stops. The pivot bearing is preferably designed in such a way that, apart from a rotation about the axis of rotation and a displacement along the axis of rotation, no further movements of the first clamping leg relative to the base plate are permitted, i.e. uncontrolled wobbling or swaying of the first clamping leg is prevented.

One embodiment of the invention provides that the pivot bearing is designed as an adjusting element of the adjusting device. This saves installation space.

In particular, the pivot bearing can comprise a bearing screw which is passed through a round hole in the base plate and is received in a threaded hole in the first clamping leg. By turning the bearing screw, the first clamping leg can be axially offset. Furthermore, the first clamping leg can be rotated around the bearing screw by direct or indirect mechanical action. Preferably, the bearing screw is at least substantially passed through the round hole without play in order to avoid wobbling of the first clamping leg.

According to one embodiment of the invention, the adjusting device comprises at least one adjusting element remote from the bearing, which is arranged at a distance from the pivot bearing with respect to the first longitudinal direction. Due to the actuating element remote from the bearing, a clamping force can be exerted on a swung-out section of the first clamping leg that is in the clamping position. In order to enable a particularly favorable introduction of force, the actuating element remote from the bearing can be arranged in the area of a leg end of the first clamping leg.

The adjusting element remote from the bearing can be an adjusting screw, which is passed through the base plate with radial movement play and is received in a threaded hole in the first clamping leg. This enables a particularly simple construction. So that there is a radial movement play, the adjusting screws can be passed through respective elongated holes or holes in the base plate that are larger than the diameter of the screw shaft.

According to one embodiment of the invention, the base plate is provided with an angularly projecting support leg, wherein the corner bearing comprises a further adjusting screw remote from the bearing, which is passed through the angularly projecting support leg with radial movement play and is received in a threaded hole in the second clamping leg. As a result, the second clamping leg of the clamping angle can not only have a supporting effect, but can also be tightened for a clamping fixation. The support leg can in particular protrude at right angles from the base plate. The adjusting screws remote from the bearing can be arranged at respective free leg ends of the first clamping leg and the second clamping leg.

A further embodiment of the invention provides that the, in particular respective, adjusting screw remote from the bearing has a countersunk head and is passed through an elongated hole in the base plate, with a receiving section for receiving the countersunk head being formed on a front side of the elongated hole facing the coupling device. If the adjusting screw remote from the bearing is guided through the elongated hole in a position offset from the receiving section and screwed into the first or second clamping leg, the countersunk head is supported on the edge of the elongated hole and is pressed laterally in the direction of the receiving section due to its force-deflecting cone shape. Together with the countersunk head, the respective clamping leg is pushed to the side. This means that the clamping leg in the insertion position is automatically moved into the clamping position when the adjusting screw remote from the bearing is screwed in, so that the assembly of the corner bearing is easier.

According to a special embodiment of the invention, the first clamping leg is tapered towards a free leg end, so that when the first clamping leg rotates in the direction of the clamping position, there is an increased freedom of movement before the swinging out free leg end hits the inner wall of the groove. The taper can be formed in that the first clamping leg is beveled on one or both sides at the free leg end.

In order to enable particularly simple and cost-effective production and also to ensure high stability, the clamping angle can be designed as a one-piece metal component, in particular as a sheet steel part.

The base plate preferably extends at least along the first longitudinal direction. This means that the base plate and the first clamping leg are aligned at least substantially parallel to one another when the first clamping leg is in position is in the insertion position. This results in favorable, elongated clamping surfaces.

A special embodiment of the invention provides that the base plate has at least one positioning element projecting from its rear side, which is designed to be inserted into the groove of the horizontal C-shaped profile element. This makes installing the corner bearing easier. The positioning element can have a width measured transversely to the first longitudinal direction, which is adapted to the width of an opening in the groove, so that lateral slipping of the base plate placed against the horizontal profile element is avoided before final clamping.

The base plate can have at least two positioning elements spaced apart from one another with respect to the first longitudinal direction, each of which protrudes from the back of the base plate and is designed for insertion into a groove of the horizontal C-shaped profile element. This ensures that the base plate is particularly securely pre-fixed to the frame. If the base plate is provided with an angularly projecting support leg, this can also have a projecting positioning element which is designed to be inserted into a groove in the vertical C-shaped profile element.

The invention also relates to a window, a door or the like with a frame which comprises interconnected C-shaped profile elements made of metal, in particular aluminum, and a sash which is secured by means of at least one corner bearing which is in a corner of the frame formed by two converging profile elements Frame is arranged, is movably mounted on the frame. According to the invention, the corner bearing is designed as described above. Such a corner bearing is particularly suitable for metal windows, metal doors and the like.

The Fig. 1-4 show a corner bearing 11 according to the invention, which forms part of a rotating fitting or tilt-and-turn fitting of a window, a door or the like. The corner bearing 11 has a base plate 13 which is used for attachment to an in Fig. 4 partially shown frame 14 of the window, door or the like is formed. The frame 14 is composed of profile elements 81, 82, which are preferably made of metal, in particular aluminum, iron or steel. An elongated, C-shaped groove 85 with an opening 87 and two opposing webs 88, 89 is formed in each of the profile elements 81, 82. In Fig. 4 only two of at least four profile elements 81, 82 of the frame 14 can be seen, namely a horizontal profile element 81 and a vertical profile element 82, which converge and thereby form a corner 90 of the frame 14, here the lower right corner 90.

In the exemplary embodiment shown, the base plate 13 extends in a first longitudinal direction 16 and is provided with a support leg 17 projecting at a right angle and extending in a second longitudinal direction 18. When the corner bearing 11 is installed, the first longitudinal direction 16 runs horizontally and the second longitudinal direction 18 runs vertically. The base plate 13 is preferably made of metal.

A coupling device 20 is arranged on a front side 15 of the base plate 13, which can be coupled in a generally known manner to a wing (not shown) of the window, door or the like in order to rotatably mount it on the frame 14. In the embodiment according to Fig. 1-4 the coupling device 20 includes an extension arm 23 and a control arm 25, which are each mounted on the base plate 13 and can be coupled to the wing via respective coupling pins 29. The extension arm 23 and the control arm 25 cross each other and are connected to one another to form an X-scissor.

To fasten the base plate 13 in the lower right corner 90 of the frame 14 there is an in Fig. 2 Separately shown clamping angle 30 is provided, which is movably mounted on a back side 33 of the base plate 13 facing away from the coupling device 20. The clamping angle 30 is preferably designed as a one-piece angled metal plate. In particular, the clamping angle 30 has a first clamping leg 35 and a second clamping leg 36 which is angled relative to this, with the corner bearing 11 in the assembled state according to Fig. 1 the first clamping leg 35 extends in the first longitudinal direction 16 and the second clamping leg 36 extends in the second longitudinal direction 18. The first clamping leg 35 and the second clamping leg 36 of the clamping angle 30 are plate-like as shown.

As in Fig. 2 As can be seen, the first clamping leg 35 and the second clamping leg 36 are provided with respective outer threaded holes 41, 42 in the area of their free leg ends 37, 39. The first clamping leg 35 is also provided with a further, inner threaded hole 43. This is arranged between the outer threaded hole 41 of the first clamping leg 35 and the second clamping leg 36. As shown, the first clamping leg 35 has bevels 46 on both sides at its free leg end 37 and is therefore tapered towards the free leg end 37.

The clamping angle 30 is mounted on the base plate 13 by means of a bearing screw 45, which is passed through a round hole 47 formed in the base plate 13 and is received in the inner threaded hole 43 of the first clamping leg 35. In particular, the bearing screw 45 guided through the round hole 47 forms a pivot bearing 50 ( Fig. 1 ), which, in addition to a rotation of the clamping angle 30 about an axis of rotation 49, also allows an axial adjustment of the clamping angle 30 along this axis of rotation 49. The axis of rotation 49 runs at right angles to the first longitudinal direction 16 and at right angles to the back 33 of the base plate 13. Furthermore, the axis of rotation 49 runs parallel to the second longitudinal direction 18. The round hole 47 is preferably adapted to the shaft diameter of the bearing screw 45 in such a way that the pivot bearing 50 has no significant radial play.

Respective adjusting screws 53, 54 remote from the bearing are accommodated in the outer threaded holes 41, 42, which are passed through elongated holes 55, 56 in the base plate 13. The elongated holes 55, 56 allow the clamping angle 30 to rotate about the axis of rotation 49 within a range of motion predetermined by the size of the elongated holes 55, 56. By screwing in the adjusting screw 53 remote from the bearing and the bearing screw 45 received in the outer threaded hole 41 of the first clamping leg 35, the first clamping leg 35 of the clamping angle 30 can be moved towards the back 33 of the base plate 13. Likewise, by screwing in the adjusting screw 54 remote from the bearing, which is accommodated in the outer threaded hole 42 of the second clamping leg 36, the second clamping leg 36 of the clamping angle 30 can be pulled in the direction of the support leg 17 of the base plate 13. The elongated holes 55, 56 also allow movements transverse to their longitudinal axis. The adjusting screws 53, 54 remote from the bearing and the bearing screw 45 thus form an adjusting device 60, by means of which the clamping angle 30 can be pulled or tightened onto the base plate 13. As in Fig. 2 The bearing screw 45 as well as the adjusting screws 53, 54 remote from the bearing can be seen as countersunk head screws.

Three positioning elements 65 spaced apart from one another are arranged on the base plate 13. Two of the positioning elements 65 protrude from the back 33 of the base plate 13, while one positioning element 65 protrudes from a side surface 66 of the support leg 17. The positioning elements 65 have a width 67 ( Fig. 3 ), which at least essentially corresponds to the width of the opening 87 of a standardized profile groove. For example, the width 67 of the positioning elements 65 can each be 10 mm. In the illustrated embodiment of the invention, the positioning elements 65 are designed as separate components that are riveted to the base plate 13. In principle, the positioning elements could 65 can also be made in one piece with the base plate 13. The clamping angle 30 covers the positioning elements 65 on the back 33 of the base plate 13 or on the side surface 66 of the support leg 17.

To attach the corner bearing 11 to the frame 14, the base plate 13 is brought up to the corner 90 of the frame 14 with the clamping angle 30 first. The clamping angle 30 and the positioning elements 65 are inserted into the openings 87 of the grooves 85 of the horizontal profile element 81 and the vertical positioning element 82, which is facilitated by the fact that the clamping angle 30 is made somewhat narrower than the openings 87 of the grooves 85. For example, the The first clamping leg 35 and the second clamping leg 36 of the clamping angle 30 must be 9.5 mm wide. The positioning elements 65 resting on the webs 88, 89 hold the base plate 13 in a defined position and prevent the base plate 13 from moving transversely to the first longitudinal direction 16.

The adjusting screw 53 remote from the bearing, which is accommodated in the end threaded hole 41 of the first clamping leg 35, is then acted upon in a lateral displacement direction by means of a tool, not shown, which in Fig. 5 is designated 77 and runs transversely to the first longitudinal direction 16. The first clamping leg 35 is rotated in a direction of rotation 78, according to Fig. 5 clockwise, rotated about the axis of rotation 49. The clamping angle 30 arrives starting from the in Fig. 5 Insertion position shown in the Fig. 6 and 7 Clamping position shown, the free leg end 37 of the first clamping leg 35 as in Fig. 6 can be seen under the bridge 88 on the left in the picture. The section of the first clamping leg 35 located between the axis of rotation 49 and the second clamping leg 36 is displaced in the opposite direction to the lateral displacement direction 77 and reaches under the web 89 on the right in the picture. The second clamping leg 36 is also displaced in the opposite direction to the lateral displacement direction 77, as shown by the arrow 79 is indicated. When the clamping angle 30 is in the clamping position, the second clamping leg 36 is as in Fig. 7 can be seen in a slightly tilted position under the web 89 of the vertical profile element 82 on the right in the picture. The clamping angle 30 is thus spread in the corner 90 of the frame 14.

The adjusting screws 53, 54 and the bearing screw 45 remote from the bearing are then screwed tight in order to clamp the webs 88, 89 of the profile elements 81, 82 between the clamping angle 30 and the base plate 13 and thus fix the base plate 13 on the frame 14.

It is not absolutely necessary to act on the adjusting screw 53 remote from the bearing using the tool in the displacement direction 77. On the front sides of the elongated holes 55, 56 there are receiving sections 92 ( Fig. 2 ) which are adapted to the countersunk heads 93 of the adjusting screws 53, 54 remote from the bearing. If the respective adjusting screw 53, 54 remote from the bearing is guided through the respective elongated hole 55, 56 in a position offset from the receiving section 92 and screwed into the relevant threaded hole 41, 42, the countersunk head 93 is supported on the edge 94 of the elongated hole 55, 56 and is pressed laterally in the direction of the receiving section 92 due to the conical shape, as a result of which the respective clamping leg 35, 36 also moves to the side. Thus, the clamping angle 30 located in the insertion position is automatically moved into the clamping position when one of the adjusting screws 53, 54 remote from the bearing is screwed in.

Fig. 8 shows an alternative embodiment of a corner bearing 11 'according to the invention, which, like the corner bearing 11 described above, has a base plate 13 and a clamping angle 30. In contrast to Fig. 1 shows this accordingly Fig. 8 designed corner bearing 11 'but an alternatively designed coupling device 20', which has a scissor arm 95 that can be coupled to the wing. The corner bearing 11 'thus forms a scissor bearing that is to be mounted in an upper corner of the frame 14. An arrangement consisting of a corner bearing 11 according to is particularly advantageous Fig. 1 and a corner bearing 11 'according to Fig. 8 for shared storage of the sash on the frame 14. Due to the rotatable clamping brackets 30, a particularly secure storage and support of the sash is guaranteed without any corrosion problems having to be expected.
