[0002] Swivel bearing device

[0003] The invention relates to a pivot bearing device according to the preamble of claim 1.

[0004] Such a pivot bearing device is already known. The assembly instructions for the ALU axxent Plus-D / DS from June 2023, page 6, section 9, "Positioning the scissors without MV," points 2 and 3, illustrate the assembly of a pivot bearing device. The known pivot bearing device is connected at its front end to a guide piece via a hinge leg, which is inserted into an undercut rebate groove of 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 assembly. 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 storage points.

[0005] From EP 1593808 B1, a fastening device for an upper hinge half is known, in which the sash 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 created by two opposing longitudinal webs that project from edge strips running perpendicular to the rebate. To fasten the hinge strap, an angled anchoring plate is inserted into the upper horizontal rebate groove in the corner region of the orthogonally running profile legs. For this purpose, the opposing longitudinal webs are removed section by section in the immediate corner region of the profile bars to allow the insertion of the leg of the anchoring plate. The anchoring plate engages behind the longitudinal webs and can be tightened by means of a clamping screw that passes through a hinge leg and has a counter-bearing in the anchoring plate.A disadvantage is that removing the longitudinal webs of the profile bars requires an additional work step, and the joint offers no adjustment options. EP 2949844 A1 discloses an adjustable joint device. The joint is multi-part, and a central joint band unit forms a cantilever arm for the hinge sleeve and a mounting flap. The mounting flap is associated with a mounting plate and supports a bearing disc whose outer circumference engages behind recesses in the mounting flap. This bearing disc also supports an adjusting screw that is guided perpendicular to the cantilever arm and engages in the mounting plate or a counter plate located on the back of the mounting plate. The adjusting screw serves to adjust the rebate spacing, and an adjustment movement moves the mounting flap with the cantilever arm. For adjustment perpendicular to the frame plane, an eccentric pin is provided, which adjusts the mounting plate horizontally.The joint mechanism is complex due to its many components and requires extensive assembly.

[0006] The object of the invention is to create a swivel bearing device that allows for easy mounting on the wing and enables a simple adjustment option perpendicular to the frame plane.

[0007] To solve this problem, the invention provides the features of claim 1. The angled design of the coupling element allows for easy positioning of the component between the legs of the rebate groove. This results in a foot width that is smaller than the distance between one web and the opposite rebate groove web, so that the foot can be guided behind one rebate groove web by means of a pivoting movement and then pivoted past the opposite rebate groove web to engage both rebate groove webs. The actuating element attached to the second leg of the coupling angle engages the corresponding webs of the rebate groove, so that no bores or recesses need to be provided in the wing.

[0008] If the second leg of the coupling angle has a width that is less 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, engage between the rebate groove webs. In order to be able to absorb the weight forces of the sash along the rebate groove, it is provided that the hinge leg is pivotably fixed at its end in a buttress on the upper horizontal sash leg.

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

[0010] A particularly simple design uses an eccentrically mounted disc as the actuator. This allows the sash to be adjusted perpendicular to the frame by rotating the actuator perpendicular to the rebate groove when the sash is open.

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

[0012] It is advantageous for handling that the locking clip 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 locking clamp grip the outer edges of the coupling angle and engage in detent recesses in the outer edges.

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

[0015] Further advantageous designs can be seen in the drawings. They show:

[0020] Fig. 10 shows a top view of the rebate groove with the coupling part mounted therein, without the hinge leg and

[0021] Fig. 11 shows a representation corresponding to Fig. 10 in a second adjustment position.

[0022] Figure 1 shows the pivot bearing device 1 with the sash open, but without the sash itself. The hinge arm 2, which is associated with the sash 3 (Figure 2), is visible. A scissor linkage 4 is attached to the hinge arm 2. The scissor linkage 4 consists of a control arm and links. The scissor linkage 4 forms a pivoting axis for the sash 3. The scissor linkage 4 is designed, in a known manner, to be concealed between the frame 5 and the sash 3 when the sash 3 is closed.

[0023] The hinge leg 2 is fixed to the sash 3. A centering pin 6 is attached to the hinge leg 2 as a coupling element. The centering pin 6 is aligned with a claw 7 of a coupling element 8 in its installed position. The coupling element 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 perpendicular vertical sash leg 11. The sash legs 10 and 11 are formed from profile bars, which are cut to length according to the required sash dimensions and connected to each other.

[0024] The rebate groove 9 has an identical structure on all wing legs 10, 11 and is bounded by two parallel rebate groove webs 13 perpendicular to the groove base 12. From the rebate groove webs 13, mutually facing webs 14 extend. 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.

[0025] As shown in Figures 1 and 2, the coupling element 8 is designed as an angled coupling angle 17 and engages with a first leg 18 in the rebate groove 9 of the horizontal wing leg 10. The second leg 19 is associated with the rebate groove 9 on the vertical wing leg 11.

[0026] Figures 3 to 8 show the procedure for assembling the wing 3. The scissor link assembly 4 with the hinge arm 2 forms a unit that is attached to the frame 5. For this purpose, the scissor link assembly 4 is attached to a mounting bracket 20. A guide piece 21 is attached to the wing 3. The guide piece 21 forms a support for the hinge arm. A pin 23 is attached to the free end 22. The pin 23 is mushroom-shaped and has flattened surfaces along two diametrically opposed outer surfaces. The dimension of the pin 23 at the cylindrical diameter is therefore larger than the dimension perpendicular to it, which applies particularly to the enlarged diameter of the head. The pin 23 is rotatably mounted in the hinge arm 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 flush with the hinge leg 2. Alternatively, a different connection between the hinge leg 2 and the guide piece 21 can be chosen. It must be ensured that the hinge leg 2 can pivot about the coupling point on the guide piece 21.

[0027] The centering pin 6 can be inserted into the rebate groove 9 by bringing the sash 3 towards the frame 5 and then sliding the sash 3 into the position shown in Fig. 4a. To secure the hinge arm 2, the coupling bracket 17 with its leg 18 is inserted into the groove 9. The leg 18 is dimensioned so that it can pass between the webs 14 (Fig. 4a). Alternatively, the leg 18 can be designed to be slightly narrower than the distance between the rebate groove web 13 and the opposite web 14. This allows the leg 18, for example, to be pivoted under the web 14 shown on the left in Fig. 4a and then pivoted clockwise past the right web 14. In the center bearing, the leg 18 then engages both webs 14.

[0028] When the leg 19 comes into contact with the vertical wing leg 11, a locking clip 25 is brought into position. The locking clip 25 is W-shaped with two longer outer arms 26 and a central arm 27. In the assembled state, the distance between the outer longitudinal edges of the arms 26 is slightly less than the distance between the webs 14. For assembly, the locking clip 25 is pressed into the rebate groove 9 of the vertical wing leg 11 (Fig. 7). Moving the locking clip 25 upwards in Fig. 7 results in the locking clip 25 being coupled to the coupling angle 17. The arm 28 overlaps the leg 19. The longitudinal edges of the leg 19 spread the arms 26 apart until they project into the recess 15. The longitudinal edges of leg 19 have detent edges into which detent projections on arms 26 engage and lock in the longitudinal direction. The locking clip completes leg 19.The coupling angle 17 is thereby fixed in the groove 9 (Fig. 8).

[0029] Figure 9 shows that an actuating element 29 is attached to the leg 19 of the coupling angle 17. The actuating element 29 is a disc 30 rotatably mounted on the leg 19, which is rotatably fastened to the leg 19 by an eccentric rivet head located on its rear side. The disc 30 has a diameter 31 that is slightly smaller than the distance 32 between the webs 14. The disc 30 has a tool engagement 33 by which the disc 30 can be rotated. The disc 30 supports the leg 19 against one of the webs 14, so that the coupling angle 17 can be adjusted from the neutral position shown in Figure 10 to the maximum position shown in Figure 11. The rotation of the disc 30 causes the claw 7 to pivot with the leg 18. This results in a change in dimension 34. This is further facilitated by the fact that the leg 18 of the coupling angle 17 is tapered towards the open claw, which allows for a range of motion in the area of ​​the claw 7.

[0030] It follows from the foregoing that the method for mounting the sash comprises at least coupling the hinge leg 2 to the sash 3 and coupling the hinge leg 2 to the coupling bracket 17, as well as securing the coupling bracket 17 in the rebate groove 9 via the retaining clip 25.
