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 for mounting in the undercut profile of the frame. The fitting is a concealed hinge. For this purpose, a bearing angle is provided which has a vertical and a horizontal leg. These are to be assigned to the corner region of the frame during assembly of the fitting. The horizontal leg of the bearing bracket is designed as a clamping part and is provided with a relation to the other dimensions of the leg tapered edge strip. This hintergeift for attachment to the undercut region of the inner leg of the profile and covered with a collar the outer leg of the profile. By means mounted in threaded holes of the horizontal leg clamping screws, which are adjustable in the direction of the outer leg of the profile, the leg is clamped. The orthogonal to the clamping part extending leg of the fitting has no attachment task and is only the investment and alignment on the vertical frame spar.

For installation of the window in the building, wings and frames are initially separated. First, the frame is aligned in the building opening, fastened and sealed. Then the wing is fixed in the frame. Due to the aforementioned embodiment, it is necessary that for mounting the already attached to the wing fitting is brought together with the wing to the frame and initially the lower hinge assembly is attached to the frame. Then the wing is aligned so that the fitting described above with the clamping part dips into the profile. Finally, the wing must be moved horizontally so far that the vertical leg of the fitting rests against the vertical frame spar and the clamping screws can be tightened.

Therefore, the assembly of the wing requires two people, with one person must hold the wing predominantly in the particular desired location, while the second person makes the coupling of the fittings with the frame and tighten the clamping screws. For larger wings, it is even necessary that three people work together. It would therefore be desirable to have a simplified assembly of the wing in the frame.

From the EP 0379866 B1 It is therefore already known to connect the wing and the frame via a relief device in the form of a rope with each other. The wing can be coupled to the frame by bringing the rope into place. The sash weight can now be largely removed over the rope, so that aligning the lower corner bearing analogous to DE 3919970 A1 can be done. The rope pulls the wing towards the frame when the sash weight becomes effective. If the attachment is made to the lower corner bearing, the upper hinge can be connected to the frame. To simplify the assembly process sees the EP 1301676 B1 while still before that the rope is splayed into a groundbreaking position from the frame.

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

From the EP 292882 A1 a fitting is known which is suitable for use on frames with undercut grooves ( 1 ) is designed. In this case, the lower, concealed wing hinge should be equipped on one of the articulated arms with a sliding piece, which is inserted into an undercut groove of the wing. On the frame a plate is fastened by means of screws, which has the pivot points of the articulated arms. To couple the wing with the frame, the joints must be assigned to each other.

This embodiment also requires that the wing is held in a defined position relative to the wing, with the complexity of the coupling process multiplied by the number of coupling points to be formed.

Clamp fixtures in undercut grooves are known per se from various applications. The DE 2516411 A1 shows a fastening of a closing part on the frame. The closing part is provided with a T-shaped foot to be assigned to the profile groove, whose longitudinal dimension is adapted to the width of the profile groove, while the width is to be dimensioned smaller than the clear distance of the legs of the profile. As a result, the foot can dive in a direction of use position 90 ° tilted alignment in the profile and engages by pivoting with the T-wings behind the profile.

The DE 20204175 U1 discloses a hinge for mounting on a frame with undercut profile groove, in which a cross-section of the profile groove has a hole for a clamping screw of a clamping element. The clamping element engages behind the inner leg of the profile and protrudes into the undercut area. This contributes to the fact that the clamping screws is associated with a cone-shaped contact surface of a reduction in the web, whose position is chosen so that the clamping element is urged in the direction of the undercut region.

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

The object of the invention is to develop a fitting part to the effect that the coupling of the wing on the frame can be done in a simplified manner.

For this purpose, the invention provides the features of the characterizing part of claim 1.

The provision of an arranged on the second angle leg and an adjacent frame leg assignable rotary claw that comes when pivoting the anchoring plate to rest against a first leg of the profile of the second frame leg and this engages against the Einschwenkbewegung leads to a distortion of the anchoring plate, thereby already in the horizontal and vertical direction is fixed in place. It is thereby ensured exactly the position required for the function of the fitting part. In addition, the sash weight can be introduced into the frame already in an early mounting state, which relieves the assembly forces.

The assembly process is simplified if the first limb is associated with a vertically extending frame limb, so that pivoting parallel to the hinge axis ensures engagement of the anchoring plate.

Although the fitting part according to the invention is particularly suitable as an upper pivot bearing of a window or a door, which is designed in particular as a concealed hinge, also a deviating from this function fitting can be designed to achieve the advantages in the manner described.

Of particular advantage is an embodiment in which the rotary claw has a U-shaped profiled edge for embracing the first leg, while the second leg is associated with an adjustable adjustable in the rotary claw securing element. It follows from this measure immediately a positive connection that secures the anchoring plate.

In order to reduce the variety of variants of the required components is provided that the rotary claw is assigned to the fitting via a Renkverbindung and pivotally engages the rotary claw with a projection in an opening and engages a radially extending to the pivot axis nose into an undercut region of the rotary claw. This development makes it possible to adapt the rotary claw possible profile dimensions independently of the anchoring plate. The rotary claw can be pivoted when mounting rotatable behind the legs of the profile.

For easy shaping of the rotary claw contributes that the projection has a circular segment-shaped cross-section.

The assembly in the profile groove is simplified in that the rotary claw is dimensioned smaller in its transverse dimension than the profile groove. The rotary claw can thereby be immersed in the profile groove and slightly pivot until the inside leg is engaged.

For correct alignment of the rotary claw with respect to the anchoring plate contributes that the rotary claw forms a plate which is located at a coupled rotary claw with the edge at a height and is thus limited in rotation.

Further advantageous embodiments will be apparent from the figures. It shows:

1 a window consisting of a frame and a wing in a partial assembly position,

2 a bottom corner bearing of the window in a mounting situation.

3 a view in the upper horizontal fold area of a window after 1 with a first embodiment of a rotary claw,

4 a three-dimensional representation of the upper corner area after 3 from the outside of the building,

5 a view of another embodiment of the rotary claw,

6 a side view of the rotary claw after 5 .

7 the end area of the anchoring plate and the rotary claw after 5 or 6 in unassembled condition,

8th the anchoring plate and the rotary claw in a partial assembly position,

9 the anchoring plate and the rotary claw in mounted position,

10 the anchoring plate with the rotary claw in mounted position in a profile groove,

11 the anchoring plate and the rotary claw behind 10 with screwed in clamping screw, and

12 the anchoring plate and the rotary claw in a view from inside.

In the 1 is the frame with 1 and the wing with 2 designated. The wing 2 and the frame 1 should have a corner camp 3 and an upper hinge 4 be connected. The upper hinge 4 is part of a display device 5 , which limits a pivoting movement about a lower horizontal axis - not shown here.

In the partial assembly step shown is the wing 2 at an angle 6 opposite the frame 1 pivoted. That at least from a mounting plate 7 and handlebars 8th . 9 existing corner store 3 is for mounting to the frame 1 introduced and by means of a lowering the handlebars 8th . 9 the mounting plate 7 assigned. Subsequently, the wing 2 pivoted around the lower corner bearing with the hinge 4 the frame edge 10 approaches.

In a further assembly step, the in 4 recognizable first thighs 11 on the vertical frame leg 12 introduced. On the thigh 11 is a clamping piece 13 attached, which with a retaining strip in the vertical profile groove 14 intervenes. The retaining strip forms in the undercut region of the inner first leg 15 a hinged connection, leaving the anchoring plate 16 by pivoting about a parallel to the frame legs 12 mounted axis and subsequent parallel displacement in the direction of the horizontal frame leg 17 at the second angle leg 18 for contact with the vertical rebate surface 19 with the profile groove 20 arrives. At the free end 21 is the angle leg 18 the anchoring plate 16 with a rotary claw 22 coupled. This essentially engages under the anchoring plate 16 and in the profile groove 20 one. As a result, the second angle leg passes 18 when swinging in the anchoring plate 16 for engagement with an inner leg 23 the profile groove 20 of the frame leg 17 and engages behind this against the Einschwenkbewegung. Because the wing 2 due to its weight and the already made coupling at the corner bearing 3 a moment in the direction of the building inside, the turning claw becomes 22 to the thigh 23 pressed on and attached to this. The final attachment can be achieved 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 respectively.

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

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

• a) coupling the corner bearing 3 with the frame,
• b) Swiveling in the wing 2 for approaching the anchoring plate 16 to the upper frame corner,
• c) Swiveling in the thigh 11 with the clamping piece 13 in the profile groove 14 .
• d) vertical displacement of the angle leg 18 with intervention of the rotary claw 22 in the profile groove 20 and
• e) Finally, the clamping screws 24 . 25 tightened.

The last assembly step fixes the anchoring plate 16 finally, according to the illustration after 4 is provided that the thigh 11 immediately a skirt for engagement in the profile groove 14 and this on the thigh 15 engages below. By means of the clamping piece 13 which is the thigh 15 is opposed by supporting and bracing on the second leg 26 a concern to the first leg 15 ensures.

Out 5 and 6 are in an enlarged view details of the rotary claw 22 can be seen, wherein the illustration relates to a second embodiment of the rotary claw. In the first embodiment is a symmetrical configuration, based on the screw axis 27 the clamping screw 25 intended ( 3 ). Therefore, this embodiment has two attachment wings 28 . 29 on. With regard to the assignment to the anchoring plate 16 the embodiments are identical. Evidently the 5 and 6 has the rotary claw 22 a U-shaped profiled edge 30 for grasping the first leg 23 on. A threaded hole 31 serves 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 the profile groove 14 so that the clamping screw 25 forms a securing element.

The rotary claw 22 is along the edge 30 with a bar 32 providing increasing strength towards the center. This narrows the groove 33 that is between the bar 32 and the collar 34 forms. The collar 34 is in the course of tapping 31 interrupted. The bar 32 flows into the fortification wing 29 , an undercut area 35 and a lead 36 having. The undercut area 35 and the lead 36 are part of a linkage, which will be described in more detail below. It is still apparent that the rotary claw 22 having a solid core, which compensates for the weakening by the clamping screw.

The Renkverbindung is based on the 7 to 12 described more clearly. The angle leg 18 is at its free end 21 with a nose 37 in the field of a plate 38 Mistake. The plate 38 has a cranked strap 39 and a guide opening passing therein 40 on. In the plate 38 is also a circular segment-shaped opening 41 , The circle segment of the opening 41 is for the tab 36 , which also has a circular segment-shaped cross section, matched. This is done in such a way that the radius of the circular arc contour of the circular segments are matched with little play in the radius, the center angle 42 but in the thigh is enlarged so that the projection 36 and thus the rotary claw 22 when engaging the projection 36 in the opening 41 can still be swiveled. The coupling is done by bringing the rotary claw 22 to the thigh 18 ( 7 ). In the second step, the lead becomes 36 in the opening 41 introduced. The nose sticks out 37 over the edge 30 the rotary claw 22 over and the edge 43 of the thigh 18 when swinging, the receding edge happens 44 , Is the plate lying 38 on the landing wing 29 on, there is a pivoting of the rotary claw 22 relative to the thigh 18 , This attacks the nose 37 in the undercut area 35 one, so one, based on by the projection 36 formed axis, achieved an axial fixation. It turns the, in 9 shown coupling connection.

The 10 to 12 show once 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 - like from the 10 in conjunction with the 4 becomes clear - part of a rebate surface of the frame 1 , An inner thigh 23 the profile groove 20 is C-shaped and forms an undercut area 45 out. The thigh 23 lies an outer thigh 46 opposite, which is T-shaped and thereby an undercut area 47 in the profile groove 20 forms. Will the fitting with the thigh 18 to the profile groove 20 introduced ( 10 ), the foot can 48 the rotary claw 22 , which is smaller in its transverse dimensions than the clear distance of the profile strips 49 . 50 between them ( 11 ). The collar is supported 34 on the thigh 23 on. The rotary claw 22 is further, as already described, in the direction of the leg 23 moves, leaving the groove 33 the bar 49 embraces. Finally, by the clamping screw 25 the turning claw against the thigh 46 supported and in the direction of the thigh 23 crowded. It is by the clamping screw 25 also causes a torque which in its direction of Einschwenkbewegung in the coupling of the rotary claw 22 with the thigh 18 equivalent. The Renkverbindung between the rotary claw and the leg 18 is thereby additionally ensured.

The embodiment described above is advantageous due to the small number of components. The rotary claw 22 can, while maintaining the basic fixing principle by dimensional adjustments of the groove 33 easy on dimensional changes of the profile groove 20 be adjusted. The embodiment according to 3 allows use with right and left hinges.

For a correct alignment of the rotary claw 22 , based on the anchoring plate 16 it is envisaged that the rotary claw 22 a plate 51 training, coupled with coupled rotary claw 22 with the edge 43 is at a height and is thus limited in rotation. The rotary claw 22 can not easily swing back. Alternatively, it can also be provided that with preassembled rotary claw 22 on the anchoring plate 16 the opening 41 is partially closed by plastic deformation, so that the movement radius of the rotary claw 22 is limited.

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