Description

Corner storage

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, the door or the like formed by converging C-shaped profile elements, and one with the Base plate ver related coupling device which can be coupled to a wing of the window, door or the like in order to store this movably on the frame.

Such corner bearings generally form components of turn fittings, tilt fittings or turn and tilt fittings. Depending on the design, corner bearings can be provided for fastening in a lower corner or in an upper corner of the window frame. Corner bearings are often concealed, that is, they are arranged completely between the frame and the casement. In order to avoid a collision between the frame and sash when the sash is rotated open despite the internal arrangement of the corner bearing, the coupling device can be designed so that the sash executes a parking movement transversely to the plane of the frame when it is opened. 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-scissors. The Koppeleinrich device can also comprise a scissor arm of a tilt and turn fitting or be designed for coupling with such a scissor arm. In this respect, a corner bearing of the type mentioned can also form a scissor bearing.

Reliable fastening of the base plate to the frame is of great importance, in particular because of 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 ten grub screws are jammed with one of the C-shaped profile elements. However, there is the problem that screws screwed into the profile elements often lead to corrosion phenomena, since the screws are usually designed as steel screws and the profile elements as aluminum parts. In addition, the different components have different coefficients of thermal expansion due to the different materials, so that the corner bearing can loosen due to differences in tension when exposed to heat or cold.

It is an object of the present invention to design a corner bearing of the type mentioned above so that the base plate can be reliably fastened to the frame without the risk of corrosion 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 bracket 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 Blendrah mens and a second clamping leg angled in relation to the first clamping leg, extending in a second longitudinal direction for fastening the base plate on a vertical C-shaped profile element of the Blendrah mens, wherein the first clamping leg of the clamping bracket is arranged on a rear side of the base plate facing away from the coupling device and is rotatable about an axis of rotation between an insertion position and a clamping position, the first being in the insertion position Clamping leg can be inserted into a groove of the horizontal C-shaped profile element and in the clamping position the first clamping leg engages behind webs of the horizontal C-shaped profile element, and the first clamping leg by means of an adjusting device in Ric H- direction of the axis of rotation can be drawn to the base plate in order to clamp the base plate to the frame in the clamping position of the first clamping leg to fixie.

The elongated clamping legs of the clamping bracket allow a larger area of the clamping or support than is possible, for example, with individual, more punctually clamping clamping plates, clamping blocks or clamping disks. Due to the two clamping legs 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 inserted position, it can be aligned paral lel to the longitudinal extension of the groove and inserted into it without the hassle of threading. 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 pivot out in opposite directions, so that one of these sections engages behind each of the two opposite webs of the horizontal C-shaped profile element. In this way, the first clamping leg can spread out laterally into the profile groove. This ensures particularly secure attachment of the base plate to the profile. The first clamping leg located in the clamping position can be used by actuating the adjusting device on the base plate to clamp the webs between the first clamping leg and the base plate and thus to attach the base plate to the horizontal profile element.

The second clamping leg is rotated when the first clamping leg is rotated from the insertion position to the clamping position and reaches a support position in which it engages behind a web of the vertical Profilele element over its entire length. In the support position, the second clamping leg, viewed in cross section, can be compared to the lateral inner walls and / or the rear be inclined towards the inner wall of the profile groove and so 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 rear of the base plate. The first clamping leg can thus spread out laterally into the horizontal C-shaped profile element when the back of the base plate is attached to the top or bottom of the horizontal profile element.

The first clamping leg is preferably 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 range within which a shift 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 slurring of the first clamping leg is prevented.

One embodiment of the invention provides that the pivot bearing is designed as an Stellele 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. The first clamping leg can be axially offset by turning the bearing screw. Furthermore, the first clamping leg can be rotated by a direct or indirect mechanical action around the bearing screw. The bearing screw is preferably at least essential play-free passed through the round hole in order to avoid wobbling of the first clamping leg.

According to one embodiment of the invention, the actuating device comprises at least one actuating element remote from the bearing, which is arranged at a distance from the pivot bearing with respect to the first longitudinal direction. Because of the adjusting element remote from the bearing, a clamping force can be exerted on a pivoted-out section of the first clamping leg located in the clamping position. In order to enable a particularly favorable introduction of force, the adjusting element remote from the bearing can be arranged in the region of one 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 of the first clamping leg. This enables a particularly simple construction. So that there is a radial 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 protruding support leg, the corner bearing comprising a further adjustment screw remote from the bearing, which is passed through the angularly protruding support leg with radial movement and is received in a threaded hole of the second clamping leg. As a result, the second clamping leg of the clamping bracket can not only have a supporting effect, but can also be tightened for a clamping fixation. The support leg can in particular protrude from the base plate at right angles. The adjusting screws remote from the bearing can be arranged on the respective free leg ends of the first clamping leg and of the second clamping leg. A further embodiment of the invention provides that the adjusting screw, in particular the respective, remote from the bearing has a countersunk head and is passed through an elongated hole in the base plate, a receiving section for receiving the countersunk head being formed on a front side of the elongated hole facing the coupling device. When the adjustment screw remote from the bearing is passed 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 conical shape that guides the force. Together with the countersunk head, the respective clamping leg is pressed to the side. Thus, the clamping leg located in the inserted 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 facilitated.

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 is rotated in the direction of the clamping position, there is an expanded range of motion before the pivoting 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 inexpensive manufacture and also to ensure high stability, the clamping bracket can be designed as a piece of metal component, in particular as a sheet steel part.

The base plate preferably extends at least along the first longitudinal direction. That is, the base plate and the first clamping leg are aligned at least substantially parallel to one another when the first clamping leg is is in the inserted 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 which protrudes from its rear side and is designed for insertion into the groove of the horizontal C-shaped profile element. This facilitates the assembly of the corner bearing. The positioning element can have a width measured transversely to the first longitudinal direction, which is adapted to the width of an opening of the groove, so that a lateral slipping of the base plate placed on the horizontal profile element is avoided before the 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 rear side of the base plate and is designed for insertion into a groove of the horizontal C-shaped profile element. This ensures a particularly secure pre-fixing of the base plate on the frame. If the base plate is provided with an angularly protruding support leg, this can also have a protruding positioning element which is designed for insertion into a groove of the vertical C-shaped profile element.

The invention also relates to a window, a door or the like with a blend frame, the interconnected C-shaped profile elements made of metal, in particular special aluminum, and a wing, the bearing by means of at least one corner that is in one by two converging profile elements formed corner of the window frame is arranged, is movably mounted on the window frame. In accordance with 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. Developments of the invention can also be found in the dependent claims, the description and the accompanying drawings.

The invention is described below by way of example with reference to the drawings.

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

In the illustrated embodiment, the base plate 13 extends in a first longitudinal direction 16 and is provided with a support leg 17 protruding at right angles, which extends in a second longitudinal direction 18. When the corner bearing 11 is installed, the first longitudinal direction 16 extends horizontally and the second longitudinal direction 18 extends 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 and can be coupled in a basically known manner to a sash, not shown, of the window, the door or the like, in order to mount it rotatably on the blind frame 14. In the embodiment according to FIGS. 1-4, the Kop peleinrichtung 20 comprises 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-scissors. To attach the base plate 13 in the lower right corner 90 of the Blendrah men 14 a separately shown in Fig. 2 clamping bracket 30 is provided, the be movable on a rear side 33 of the base plate 13 facing away from the coupling device 20 is mounted. The clamping bracket 30 is preferably designed as a one-piece abge angled metal plate. Specifically, the clamping bracket 30 has a first clamping leg 35 and a second clamping leg 36 angled relative to this, wherein in the assembled state of the corner bearing 11 according to FIG. 1, the first clamping leg 35 in the first longitudinal direction 16 it stretches and the second clamping leg 36 in the second longitudinal direction 18 extends. The first clamping leg 35 and the second clamping leg 36 of the clamping bracket 30 are plate-like, as shown.

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

The clamping bracket 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 received in the inner threaded hole 43 of the first clamping leg 35. Specifically, 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 bracket 30 about a rotation axis 49, also allows an axial adjustment of the clamping bracket 30 along this rotation axis 49. The axis of rotation 49 runs at right angles to the first longitudinal direction 16 and at right angles to the rear side 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.

In the outer threaded holes 41, 42 respective bearing-remote set screws 53, 54 are added, which leads through elongated holes 55, 56 of the base plate 13 through. The elongated holes 55, 56 allow a rotary movement of the clamping bracket 30 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 outer thread hole 41 of the first clamping leg 35 recorded remote from the bearing adjusting screw 53 and the bearing screw 45, the first clamping leg 35 of the clamping bracket 30 in the direction of the back 33 of the base plate 13 can be moved. Likewise, by screwing in the set screw 54 remote from the bearing and received in the outer threaded hole 42 of the second clamping leg 36, the second clamping leg 36 of the clamping bracket 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 transversely 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 used or tightened on the base plate 13.

As can be seen in FIG. 2, the bearing screw 45, like the adjusting screws 53, 54 remote from the bearing, are designed as countersunk 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 rear side 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 65 can also be made in one piece with the base plate 13. The clamping bracket 30 covers the positioning elements 65 on the rear side 33 of the base plate 13 or on the side surface 66 of the support leg 17.

To fasten the corner bearing 11 to the window frame 14, the base plate 13 is brought up to the corner 90 of the window frame 14 with the clamping bracket 30 first. The clamping bracket 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 relements 82, which is facilitated by the fact that the clamping bracket 30 is made somewhat narrower than the openings 87 of the grooves 85 the first clamping leg 35 and the second clamping leg 36 of the clamping bracket be 309.5 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 being displaced transversely to the first longitudinal direction 16.

Subsequently, the threaded hole 41 at the end of the first clamping sockets 35 received the adjustment screw 53 remote from the bearing by means of a tool (not shown) in a lateral displacement direction, denoted by 77 in FIG. 5 and extending transversely to the first longitudinal direction 16. The first clamping leg 35 is rotated in a direction of rotation 78, clockwise according to FIG. 5, about the axis of rotation 49. Starting from the insertion position shown in FIG. 5, the clamping bracket 30 moves into the clamping position shown in FIGS. 6 and 7, the free leg end 37 of the first clamping leg 35 as seen in FIG. 6 under the web 88 on the left in the picture device. The located between the axis of rotation 49 and the second clamping leg 36 portion of the first clamping leg 35 is moved opposite to the lateral displacement direction 77 and comes under the web 89 on the right in the picture. The second clamping leg 36 is also moved opposite to the lateral displacement direction 77, as indicated by arrow 79. When the Klemmwin angle 30 is in the clamping position, the second clamping leg 36 is as in FIG 7 is arranged in a slightly tilted position under the web 89 of the vertical profile element 82 on the right in the picture. The clamping bracket 30 is thus spread apart in the corner 90 of the window frame 14.

Then the remote set screws 53, 54 and the bearing screw 45 are screwed tight to clamp the webs 88, 89 of the profile elements 81, 82 between tween the clamping bracket 30 and the base plate 13 and fix the base plate 13 to the frame 14.

The application of the adjusting screw 53 remote from the bearing by means of the tool in the displacement direction 77 is not absolutely necessary. On the front sides of the elongated holes 55, 56 receiving sections 92 (FIG. 2) are formed which are adapted to the countersunk heads 93 of the adjusting screws 53, 54 remote from the bearing. When the respective adjusting screw 53, 54 remote from the bearing is passed 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 border 94 of the elongated hole 55, 56 from and is pressed because of the conical shape since Lich in the direction of the receiving portion 92, whereby the respective clamping leg 35, 36 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.

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 bracket 30. In contrast to FIG. 1, however, the corner bearing 11 ′ designed according to FIG. 8 has 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 window frame 14. An arrangement of a corner bearing 11 according to FIG. 1 and a corner bearing 11 'according to FIG. 8 for joint storage is particularly advantageous of the sash on the frame 14. Due to the rotatable clamping bracket 30, a particularly secure mounting and support of the sash is guaranteed without corrosion problems to be expected.
