Description

[0001] The invention relates to a pivot bearing device according to the preamble of claim 1.

[0002] Such a pivot bearing device is already known. The installation of a pivot bearing device is shown on page 6, under point 9. Positioning the scissors without MV, points 2 and 3, of the ALU axxent Plus-D / DS installation instructions from June 2023. The known pivot bearing device is attached to a guide piece at the front end by means of a hinge leg, which is inserted into an undercut rebate groove in the sash. The pivot bearing device is then pivoted 30° away from the rebate surface, and a pressure plate is inserted into the rebate groove. The pressure plate has a bore into which a centering pin of the pivot bearing device engages and locks during installation. The centering pin supports the pivot bearing device in the rebate groove of the sash, perpendicular to the rebate. The hinge leg absorbs the forces occurring along the rebate groove and mediates between the pivot bearing and the sash.At the same time, the hinge leg provides space for bearing points.

[0003] EP 1593808 B1 discloses a fastening device for an upper hinge half in which the wing is composed of two vertical and two horizontal profile bars, and the profile bars form a rebate groove with longitudinal webs. The rebate groove forms undercut areas formed by two mutually facing longitudinal webs that protrude from edge strips running perpendicular to the rebate. To fasten the hinge, an angular anchoring plate is inserted into the upper horizontal rebate groove in the corner area of ​​the orthogonally running profile legs. For this purpose, the mutually facing longitudinal webs are removed in sections in the immediate corner area of ​​the profile bars to allow the leg of the anchoring plate to be inserted. The anchoring plate engages behind the longitudinal webs and can be tightened using a clamping screw that passes through a hinge leg and has an abutment in the anchoring plate.The disadvantage is that the removal of the longitudinal webs of the profile bars requires an additional operation and the joint does not offer any adjustment options.

[0004] EP 2949844 A1 discloses an adjustable joint device. The joint is multi-part, and a central hinge unit forms a cantilever arm for the hinge sleeve and a mounting lug. The mounting lug can be assigned to a mounting plate and supports a bearing disc, the outer circumference of which engages behind recesses in the mounting lug and supports an adjusting screw that is guided perpendicular to the cantilever arm and engages in the mounting plate or a counter-plate attached to the rear of the mounting plate. The adjusting screw is used to adjust the rebate spacing, and with an adjusting movement, the mounting lug is moved with the cantilever arm. For adjustment perpendicular to the frame plane, an eccentric pin is provided, which adjusts the mounting plate horizontally. The joint device is complex due to its many components and requires laborious assembly.

[0005] The object of the invention is to provide a pivot bearing device which allows simple installation on the sash and enables simple adjustment perpendicular to the frame plane.

[0006] To achieve this object, the invention provides the features of claim 1. The angular design of the coupling element allows for easy positioning of the component between the legs of the rebate groove. As a result, the width of the foot is smaller than the distance between a web and the opposite rebate groove web, so that the foot can be guided behind a rebate groove web by means of a pivoting movement and then pivoted past the opposite rebate groove web to engage behind both rebate groove webs. The actuator attached to the second leg of the coupling angle engages the mutually facing webs of the rebate groove, so that no holes or recesses are required in the sash.

[0007] If the second leg of the coupling angle has a width that is smaller than the clear distance between the webs, then the second leg of the coupling angle can, due to its dimension perpendicular to the rebate groove, enter between the rebate groove webs.

[0008] In order to be able to absorb the weight forces of the sash along the rebate groove, the hinge leg is pivotally fixed at its end in an abutment on the upper horizontal sash leg.

[0009] The distance between the upright sash leg and frame leg can be adjusted if the abutment is adjustable along the rebate groove.

[0010] A particularly simple design provides for the actuator to be an eccentrically mounted disc. The sash can thus be adjusted perpendicular to the frame with the sash open by rotating the actuator perpendicular to the rebate groove.

[0011] In order to enable particularly simple assembly and to fix the coupling angle in the assembly position, it can be provided that a safety clamp can be assigned to the second leg, which on the one hand locks onto the leg and on the other hand engages under the webs with arms.

[0012] It is advantageous for handling that the safety clamp is W-shaped and the middle shorter arm engages in a locking recess of the leg.

[0013] A further development provides that the outer legs of the securing clip encompass the outer edges of the coupling angle and engage in locking recesses in the outer edges.

[0014] For coupling with the hinge leg, the coupling link for the horizontal hinge leg is a cylindrical centering pin, which is encompassed by the coupling angle with a U-shaped claw.

[0015] Further advantageous embodiments are shown in the drawings. They show: Fig. 1, omitting the wing, a spatial view of part of a hinge device, Fig. 2 a view of the corner area of ​​a wing with a coupling part, Fig. 3 a first partial assembly step of the wing with the pivot bearing device, Fig. 4 a second partial assembly step of the wing with the pivot bearing device, Fig. 4a The partial assembly step according to Fig. 4 in a second view, Fig. 5 a third partial assembly step of the wing with the pivot bearing device, Fig. 6 a fourth partial assembly step of the wing with the pivot bearing device, Fig. 7 a final partial assembly step of the wing with the pivot bearing device, Fig. 8 the fully assembled swivel bearing device, Fig. 9 Adjustment of the swivel bearing device Fig. 10 a view from above of the rebate groove with the coupling part mounted therein without the hinge leg and Fig. 11 a representation corresponding Fig. 10 in a second adjustment position.

[0016] In the Fig. 1 shows the pivot bearing device 1 with the wing open without the wing. The hinge leg 2 is visible, which is attached to the wing 3 ( Fig. 2). A scissor link assembly 4 is attached to the hinge leg 2. The scissor link assembly 4 consists of a control arm and links. The scissor link assembly 4 forms a shifting axis of rotation for the sash 3. The scissor link assembly 4 is designed in a known manner to be concealed between the frame 5 and the sash 3 when the sash 3 is closed.

[0017] The hinge leg 2 is fixed to the sash 3. A centering pin 6 is attached to the hinge leg 2 as a coupling link. In the installed position, the centering pin 6 is assigned to a claw 7 of a coupling link 8. The coupling link 8 is mounted in a rebate groove 9 of the sash 3. The rebate groove 9 runs along the upper horizontal sash leg 10 and the orthogonal vertical sash leg 11. The sash legs 10, 11 are formed from profile bars that are cut to length and connected to each other according to the required sash dimensions.

[0018] The rebate groove 9 is identically constructed on all sash legs 10, 11 and is defined by two parallel rebate groove webs 13 extending perpendicular to the groove base 12. Webs 14 project from the rebate groove webs 13, facing one another. An undercut area 15 is formed between the groove base 12, the rebate groove web 13, and the web 14. The rebate groove webs 13 and the webs 14 are symmetrical with respect to a longitudinal center axis of the rebate groove 9. Therefore, identical reference numerals are used for both sides.

[0019] According to the Fig. 1 and Fig. 2, the coupling member 8 is designed as an angular coupling bracket 17 and engages with a first leg 18 into the rebate groove 9 of the horizontal wing leg 10. The second leg 19 is assigned to the rebate groove 9 on the vertical wing leg 11.

[0020] The Fig. 3 to 8 show the procedure for assembling the sash 3. The scissor link arrangement 4 with the hinge leg 2 forms an assembly that is fastened to the frame 5. For this purpose, the scissor link arrangement 4 is fastened to a mounting bracket 20. A guide piece 21 is attached to the sash 3. The guide piece 21 forms an abutment for the hinge leg. A pin 23 is attached to the free end 22. The pin 23 is mushroom-head-shaped and provided with flattened portions along two diametrically opposed outer surfaces. The dimension of the pin 23 at the cylindrical diameter is therefore larger than the dimension transverse to it, which applies in particular to the enlarged head. The pin 23 is rotatably mounted in the hinge leg 2 and is provided with an actuating tab 24 at its end.The pin 23 can thus be coupled to the guide piece 21 in a first position and is locked to the guide piece 21 in a second position, in which the actuating tab 24 is aligned flush with the hinge leg 2. Alternatively, a different connection between the hinge leg 2 and the guide piece 21 can also be selected. It must be ensured that the hinge leg 2 can pivot about the coupling point on the guide piece 21.

[0021] The centering pin 6 can be inserted into the rebate groove 9 by bringing the sash 3 closer to the frame 5 and moving the sash 3 into the position according to Fig. 4a. In order to fix the hinge leg 2, the coupling angle 17 with the leg 18 is inserted into the groove 9. The leg 18 is dimensioned so that it fits between the webs 14 ( Fig. 4a). Alternatively, the leg 18 can also be designed so that it is slightly narrower than the distance between the rebate groove web 13 and the opposite web 14. This allows the leg 18 to be inserted, for example, under the Fig. 4a, the leg 18 is pivoted into the left-hand web 14 shown in FIG. 4a and then pivoted clockwise past the right-hand web 14. In the center bearing, the leg 18 then engages behind both webs 14.

[0022] When the leg 19 comes into contact with the vertical wing leg 11, a securing clip 25 is brought forward. The securing clip 25 is W-shaped with two outer longer arms 26 and a middle arm 27. The distance between the outer longitudinal edges of the arms 26 is slightly smaller in the assembled state than the distance between the webs 14. For assembly, the securing clip 25 is pressed into the rebate groove 9 of the vertical wing leg 11 ( Fig. 7). Moving the safety clamp 25 in the Fig. 7 upwards leads to the coupling of the securing clamp 25 with the coupling bracket 17. The arm 28 engages over the leg 19. The longitudinal edges of the leg 19 spread the arms 26 and spread them open until they protrude into the undercutting area 15. The longitudinal edges of the leg 19 have locking edges into which locking projections on the arms 26 engage and fix them in the longitudinal direction. The securing clamp complements the leg 19. The coupling bracket 17 is thereby fixed in the groove 9 ( Fig. 8).

[0023] From the Fig. 9 shows that an actuator 29 is attached to the leg 19 of the coupling bracket 17. The actuator 29 is a disk 30 which is rotatably mounted on the leg 19 and which is rotatably fastened to the leg 19 by means of an eccentric rivet attachment arranged on the rear. The disk 30 has a diameter 31 which is slightly smaller than the distance 32 between the webs 14. The disk 30 has a tool engagement 33 with which the disk 30 can be rotated. The disk 30 supports the leg 19 against one of the webs 14, so that the coupling bracket 17 can be rotated starting from the Fig. 10 shown neutral position into the position shown in the Fig. 11 visible maximum setting is adjustable. By rotating the disc 30, the claw 7 pivots with the leg 18. This causes a change in the dimension 34. This is contributed to by the fact that the leg 18 of the coupling angle 17 is tapered towards the open claw, which allows for freedom of movement in the area of ​​the claw 7.

[0024] From the above it follows that the method for assembling the wing comprises at least coupling the hinge leg 2 to the wing 3 and coupling the hinge leg 2 to the coupling angle 17 as well as fixing the coupling angle 17 in the rebate groove 9 via the securing clip 25.
