EP3204584B1 - Angular fitting - Google Patents

Description

The invention relates to an angular fitting according to the preamble of claim 1. Fittings of this type are already known. the EP 1918498 A1 discloses a fitting to be anchored in the undercut profile groove of the frame for assembly. The fitting is a concealed hinge. For this purpose, a bearing bracket is provided which has a vertical and a horizontal leg. These are assigned to the corner area of the frame when installing the fitting. The horizontal leg of the bearing bracket is designed as a clamping part and is provided with an edge strip that is tapered compared to the other dimensions of the leg. For fastening, this grips the undercut area of the inner leg of the profile groove and covers the outer leg of the profile groove with a collar. The leg is clamped by means of clamping screws which are mounted in threaded holes in the horizontal leg and which can be adjusted in the direction of the outer leg of the profile groove. The leg of the fitting running orthogonally to the clamping part has no fastening task and is only used for installation and alignment on the vertical frame member.

To install the window in the building, the sash and frame are first separated. First the frame is aligned, fixed and sealed in the building opening. The sash is then attached to the frame. Due to the aforementioned configuration, it is necessary for assembly of the fitting already attached to the wing to be brought together with the wing to the frame and first the lower hinge arrangement is attached to the frame. Then the sash is aligned so that the fitting described above dips into the profile groove with the clamping part. Finally, the sash must be moved horizontally until the vertical leg of the fitting is in contact with the vertical frame member and the clamping screws can be tightened.

The assembly of the wing therefore requires two people, one person must keep the wing mostly in the desired position, while the second person Coupling the fittings with the frame and tightening the clamping screws. With larger wings, it is even necessary for three people to work together. A simplified assembly of the sash in the frame would therefore be desirable.

From the EP 0379866 B1 it is therefore already known to connect the wing and the frame to one another via a relief device in the form of a cable. The sash can be connected to the frame by feeding and hanging the rope. The weight of the sash can now be largely carried off via the cable, so that the lower corner bearing can be aligned in the same way as for DE 3919970 A1 can be done. The cable pulls the sash towards the frame when the sash weight takes effect. Once it has been attached to the bottom corner bearing, the top hinge can be connected to the frame. To simplify the assembly process, see the EP 1301676 B1 It is also assumed that the rope is spread out in a position pointing away from the frame.

These configurations are not designed for mounting on frames with undercut profile grooves and therefore cannot be clamped.

From the EP 292882 A1 a fitting is known for use on frames with undercut grooves ( 1 ) is designed. The lower, concealed wing hinge on one of the articulated arms should be equipped with a sliding piece which can be pushed into an undercut groove in the wing. A plate is attached to the frame with screws, which has the pivot points of the articulated arms. To couple the sash to the frame, the joint points must be assigned to each other.

This configuration also presupposes that the wing is held in a defined position relative to the wing, with the complexity of the coupling process multiplying with the number of coupling points to be formed.

In the DE 102007054476 A1 discloses a link assembly of a corner fitting of a window or door. The fitting, which is concealed in the rebate area between the sash and the frame, is provided with a mounting plate on which a pivoting arm is mounted. A support arm is pivotably mounted on the deployment arm and forms an X-shaped deployment device with the deployment arm. One free end of the support arm is assigned to the wing and supports it. The other free end of the support arm has a backdrop with a rectangular outline, which is slidably guided in an undercut frame groove of the frame. When the sash is opened, the connecting link is shifted in the frame groove. For assembly, the backdrop is provided with a foot that has edges trimmed along a diagonal line parallel to it. When the diagonals are aligned parallel to a longitudinal axis of the groove, this foot can be inserted into the free space of the frame groove and by turning the corner fitting, the foot engages behind the undercut and prevents it from escaping from the frame groove. With the attachment of the corner fitting, the attachment is complete and the position of the connecting link is secured. This embodiment provides for exclusive attachment of the corner fitting. It is not possible or intended to install the patch fitting together with the sash.

Clamp fastenings in undercut grooves are known per se from various applications. the DE 2516411 A1 shows an attachment of a locking part to the frame. The closing part is provided with a T-shaped foot assigned to the profile groove, the longitudinal dimension of which is adapted to the width of the profile groove, while the width should be dimensioned smaller than the clear distance between the legs of the profile groove. As a result, the foot can enter the profile groove in a 90° swiveled orientation to the position of use and, by swiveling the T-wings, can reach behind the profile groove.

the DE 20204175 U1 discloses a hinge for mounting on a frame with an undercut profile groove, in which a web that overlaps the profile groove has a bore for a clamping screw of a clamping element. The clamping element grips behind the inner leg of the profile groove and protrudes into its undercut area. The fact that the clamping screws are assigned a cone-shaped contact surface to a countersink in the web, the position of which is selected such that the clamping element is pushed in the direction of the undercut region, contributes to this.

These latter solutions are not suitable for all fitting components, since the types of stress vary.

The object of the invention is to further develop a fitting part in such a way that the coupling of the sash to the frame can take place in a simplified manner.

To this end, the invention provides the features of the characterizing part of claim 1.

The provision of a rotary claw (22) arranged on the angle leg (18) of the anchoring plate (16) and assignable to an adjacent frame leg, which has a U-shaped profiled edge (30) for gripping around the first leg (23) of the profiled groove (14), while the second leg (46) of the profile groove (14) is assigned a securing element which is adjustably mounted in the rotary claw, so that the rotary claw (22) when the anchoring plate (16) is swiveled in to rest against the first leg (23) of the profile groove (20) of the second Frame piece (17) reaches and engages behind it against the inward pivoting movement, leads to a distortion of the anchoring plate, which is thus already fixed in place in the horizontal and vertical direction. This ensures that the exact position is required for the fitting to function. In addition, the weight of the sash can be introduced into the frame at an early stage of assembly, which relieves the assembly forces.

In order to reduce the number of variants of the required components, it is provided that the rotary claw is assigned to the fitting via a bayonet connection and for this purpose the rotary claw engages in an opening with a projection and a nose running radially to the pivot axis engages in an undercut area of the rotary claw. This further development makes it possible to adapt the rotary claw to possible profile dimensions independently of the anchoring plate. The rotary claw can be pivoted behind the leg of the profile groove during assembly.

The fact that the projection has a cross section in the shape of a segment of a circle contributes to the simple shaping of the rotary claw.

Installation in the profile groove is simplified by the fact that the transverse dimension of the rotary claw is smaller than that of the profile groove. The rotary claw can be immersed in the profile groove and swiveled slightly until the inside leg is gripped underneath.

The correct orientation of the rotary claw in relation to the anchoring plate contributes to the fact that the rotary claw forms a plate which, when the rotary claw is coupled, is at the same height as the edge and is thus limited in terms of rotation.

In the 1 the frame is denoted by 1 and the wing by 2. The leaf 2 and the frame 1 should be connected via a corner bearing 3 and an upper hinge 4. The upper hinge 4 is part of a deployment device 5, which a pivoting movement about a lower horizontal axis - not shown here - limited.

In the partial assembly step shown, the wing 2 is pivoted by an angle 6 with respect to the frame 1 . The corner bearing 3, which consists of at least one mounting plate 7 and links 8, 9, is brought up to the frame 1 for assembly and the links 8, 9 are assigned to the mounting plate 7 by means of a lowering movement. The wing 2 is then pivoted about the lower corner bearing, with the hinge 4 approaching the frame edge 10 .

In a further assembly step, the in 4 recognizable first leg 11 brought up to the vertical frame leg 12. A clamping piece 13 is attached to the leg 11 and engages in the vertical profile groove 14 with a holding strip. The retaining strip forms a hinge-like connection in the undercut area of the inner first leg 15, so that the anchoring plate 16 can be pivoted about an axis mounted parallel to the frame leg 12 and then parallelly displaced in the direction of the horizontal frame leg 17 on the second angle leg 18 to rest against the vertical Rebate surface 19 reaches the profile groove 20. At the free end 21 of the angle leg 18 is the Anchoring plate 16 coupled to a rotary claw 22. This essentially engages under the anchoring plate 16 and in the profile groove 20 . As a result, when the anchoring plate 16 is swiveled in, the second angle leg 18 comes into contact with an inner leg 23 of the profile groove 20 of the frame leg 17 and engages behind this against the swiveling-in movement. Since the wing 2 experiences a moment towards the inside of the building due to its weight and the coupling that has already taken place on the corner bearing 3 , the rotary claw 22 is pressed against the leg 23 and rests against it. The final attachment can be done by tightening the clamping screws 24 on the first leg 11 and the clamping screw 25 on the angle leg 18 or the rotary claw 22.

2. b) Einschwenken des Flügels 2 zur Annäherung der Verankerungsplatte 16 an die obere Rahmenecke,
3. c) Einschwenken des Schenkels 11 mit dem Klemmstück 13 in die Profilnut 14,
4. d) vertikales Verschieben des Winkelschenkels 18 mit Eingreifen der Drehkralle 22 in die Profilnut 20 und
5. e) abschließend werden die Klemmschrauben 24, 25 festgezogen.

The assembly method of the wing 2 on the frame 1 therefore includes at least the assembly steps

1. a) coupling the corner bearing 3 to the frame,
2. b) swinging in the sash 2 to bring the anchoring plate 16 closer to the upper corner of the frame,
3. c) Pivoting the leg 11 with the clamping piece 13 into the profile groove 14,
4. d) vertical displacement of the angle leg 18 with engagement of the rotary claw 22 in the profile groove 20 and
5. e) Finally, the clamping screws 24, 25 are tightened.

The final assembly step finally secures the anchoring plate 16, as shown in FIG 4 it is provided that the leg 11 directly has an edge strip for engaging in the profile groove 14 and this engages under the leg 15 . By means of the is clamping piece 13 , which is opposite the leg 15 , abutment on the first leg 15 is ensured by supporting and bracing on the second leg 26 .

Out Figures 5 and 6 details of the rotary claw 22 can be seen in an enlarged representation, the representation relating to a second exemplary embodiment of the rotary claw. In the first exemplary embodiment, a symmetrical design is provided in relation to the screw axis 27 of the clamping screw 25 ( 3 ). Therefore, this embodiment has two attachment wings 28,29. With regard to the assignment to the anchoring plate 16, the exemplary embodiments are identical. According to the Figures 5 and 6 the rotary claw 22 has a U-shaped profiled edge 30 for embracing the first leg 23 . A threaded hole 31 is used for the exception of the clamping screw 25, which is not shown here. The clamping screw 25 passes through the threaded hole and allows a Support on the second leg 26 of the profile groove 14, so that the clamping screw 25 forms a securing element.

The rotary claw 22 is provided along the edge 30 with a ridge 32 which has an increasing thickness towards the center. As a result, the groove 33 that forms between the strip 32 and the collar 34 narrows. The collar 34 is interrupted in the course of the threaded bore 31 . The strip 32 ends in the fastening wing 29 which has an undercut area 35 and a projection 36 . The undercut area 35 and the projection 36 are part of a bayonet connection, which will be described in more detail below. It can also be seen that the rotary claw 22 has a solid core that compensates for the weakening caused by the clamping screw.

The Renk connection is based on the Figures 7 to 12 described more clearly. The angle leg 18 is provided at its free end 21 with a nose 37 in the area of a plate 38 . The plate 38 has an offset bracket 39 and a guide opening 40 merging therein. In the plate 38 there is also an opening 41 in the shape of a segment of a circle. The segment of a circle of the opening 41 is matched with respect to the projection 36, which also has a cross section in the shape of a segment of a circle. This is done in such a way that the radius of the circular arc contour of the circle segments is matched with little play in the radius, but the central angle 42 is enlarged in the leg so that the projection 36 and thus the rotary claw 22 can still be pivoted when the projection 36 engages in the opening 41. The coupling takes place by moving the rotary claw 22 to the leg 18 ( 7 ). In the second step, the projection 36 is inserted into the opening 41 . The nose 37 protrudes over the edge 30 of the rotary claw 22 and the edge 43 of the leg 18 passes the receding edge 44 during pivoting. If the plate 38 rests on the fastening wing 29, the rotary claw 22 pivots relative to the leg 18 the lug 37 engages in the undercut area 35 so that, based on the axis formed by the projection 36, an axial fixation is achieved. It turns the, in 9 shown coupling connection.

the Figures 10 to 12 show again on an enlarged scale and in different assembly phases the interaction of the rotary claw 22 with the profile groove 20. The profile groove 20 is - as from the Fig.10 in connection with the 4 becomes clear - part of a rebate surface of the frame 1. An inner leg 23 of the profile groove 20 is C-shaped and forms an undercut area 45 from. Opposite the leg 23 is an outer leg 46 which is T-shaped and thereby forms an undercut region 47 in the profile groove 20 . If the fitting with the Leg 18 brought up to the profile groove 20 ( 10 ), the foot 48 of the rotary claw 22, which is smaller in its transverse dimensions than the clear distance between the profile strips 49, 50 can enter between them ( 11 ). In this case, the collar 34 is supported on the leg 23 . As already described, the rotary claw 22 is then moved in the direction of the leg 23 so that the groove 33 encompasses the strip 49 . Finally, the rotary claw is supported against the leg 46 and pushed in the direction of the leg 23 by the clamping screw 25 . In this case, the clamping screw 25 also causes a torque which corresponds in its direction to the swiveling-in movement when the rotary claw 22 is coupled to the leg 18 . This additionally ensures the bayonet connection between the rotary claw and the leg 18 .

The configuration described above is advantageous because of the small number of components. The rotary claw 22 can easily be adapted to dimensional changes in the profile groove 20 by dimensional adjustments to the groove 33 while retaining the basic fastening principle. The embodiment after 3 allows use with right and left hinges.

In order to achieve a correctly aligned alignment of the rotary claw 22 relative to the anchoring plate 16, it is provided that the rotary claw 22 forms a plate 51 which, when the rotary claw 22 is coupled, is at the same height as the edge 43 and is thus limited in terms of rotation. As a result, the rotary claw 22 cannot easily pivot back. Alternatively, provision can also be made for the opening 41 to be partially closed by plastic deformation when the rotary claw 22 is preassembled on the anchoring plate 16, so that the radius of movement of the rotary claw 22 is limited.

Deviating from this, a plastic deformation can also be provided on the edge 43, so that this edge 43 always strikes the plate 51.
