ASSEMBLY AID FOR A BEARING CONTAINING TWO BEARING PARTS

Description

[0001] The invention relates to an assembly aid for a bearing comprising two bearing parts of a sash of a window, a French door or the like which pivots against a frame, comprising an alignment element for detachable connection with a first bearing part and a guide element for guiding a bearing bolt of a second bearing part to the first bearing part, wherein the alignment element has a sleeve partially encompassing a bearing band of the first bearing part and the guide element is arranged on the sleeve.

[0002] Such an assembly aid is known, for example, from WO 2006 / 134615. This assembly aid has a guide element. The guide element has a base body which can be coupled to a first half of the bearing. A sliding element projects from the base body, along which the second half of the bearing can slide.

[0003] German patent DE 297 06 761 U1 discloses a hinge insertion aid for particularly easy insertion of a door into hinges on a frame. The insertion aid is U-shaped and is inserted between the hinge and the frame.

[0004] From FR 2 702 174 A1, an insertion aid for bearings is known in which a pincer-like element is designed for gripping the bearing part containing the bearing pin. The other bearing part can be inserted into the gripped bearing part.

[0005] An installation aid is known, for example, from EP 1 041 231 A2. This installation aid makes it possible to hang two hinges simultaneously on heavy doors. For this purpose, a guide body, which can be detachably attached to a fixed hinge part, has a guide track for a movable hinge part. However, this installation aid is only suitable for hinge parts that are permanently connected to the door leaf and the frame.

[0006] However, in windows or French doors, a corner hinge located in the lower area usually has a pivoting bearing bolt, which allows the sash to be moved into a tilting position. This creates two problems when mounting the sash to the frame: firstly, the intended alignment of the sash to the frame, and secondly, the alignment of the partially movable hinge components.

[0007] From WO 2014 / 026942 A1, a corner hinge for a window became known in which one corner hinge bolt has a rotation lock. However, this results in a high manufacturing cost for the hinge. In addition, this rotation lock does not help with aligning the sash with the frame.

[0008] The invention is based on the problem of further developing an assembly aid of the type mentioned at the outset in such a way that it enables the connection of the bearing parts, in particular a bearing designed as a corner bearing, during the assembly of the wing in the frame.

[0009] This problem is solved according to the invention by the fact that the guide element is designed to guide a bearing bolt of the second bearing part and that the sleeve has a ramp pointing radially inwards into the movement area of ​​the bearing bolt of the second bearing part, so that the sleeve is pushed away from the bearing bolt when the bearing bolt is inserted into the bearing strip.

[0010] This design allows the sleeve to be connected to the first bearing component, thereby aligning the guide element for the second bearing component relative to the first. During window installation, the guide element guides the second bearing component into the first. The installation aid can then be removed, and the bearing is installed. The guide element can be designed in virtually any way to align the second bearing component relative to the first. This aligns the bearing components while the sash is being installed in the frame. To simplify handling of the installation aid, the sleeve features a radially inward-facing ramp that extends into the movement range of the bearing bolt of the second bearing component. This design pushes the sleeve away from the bearing bolt when the bolt is inserted into the bearing band.A fitter can therefore see from the sleeve whether the corner bearing is mounted as intended. With a suitable design of the bearing band, the ramp preferably protrudes through an opening into the bearing band, so that the sleeve is only pushed aside once the bearing is installed.

[0011] According to an advantageous embodiment of the invention, a detachable fastening of the assembly aid is particularly simple if the alignment element has a holding device for locking or clamping to the bearing.

[0012] According to another advantageous embodiment of the invention, the holding device is structurally particularly simple if it has detent elements arranged on the sleeve for securing it to the first bearing part of the bearing. Preferably, the detent elements project radially inwards from the sleeve.

[0013] According to another advantageous embodiment of the invention, further simplification of the holding device is facilitated if the holding device has clamping ribs arranged on the sleeve for holding it on the first bearing part of the bearing.

[0014] According to another advantageous embodiment of the invention, guiding the bearing components during the assembly of the sash to the frame is particularly simple if the guide element has a ramp arranged on one end face of the sleeve. This design allows a pivotable bearing bolt of the second bearing component, which is common in corner bearings, to be lifted and guided into the bearing band.

[0015] The ramp arranged on the front face can be aligned so that the bearing bolt is lifted and inserted into the C-shaped sleeve. However, according to another advantageous embodiment of the invention, such alignment can be easily avoided if a ramp arranged on the front face is designed as an insertion funnel.

[0016] According to another advantageous embodiment of the invention, the sleeve can be easily gripped if a ridge protrudes from the outside of the sleeve to serve as a handle.

[0017] According to another advantageous embodiment of the invention, the assembly aid can be easily and readily positioned on the frame or sash if the handle's web has dimensions designed for locking into a profile groove of the frame or sash. This contributes to a high level of user comfort. Preferably, the handle has two webs for this purpose, which enable it to be clamped in the profile groove.

[0018] According to the invention, the assembly aid can be used flexibly if the guide element has two separate ramps. This design makes it easier to bend the ramps radially outwards, so that the sleeve can also be pushed over the first bearing part from above.

[0019] According to an advantageous embodiment of the invention, the assembly aid can be conveniently removed from the first bearing part after assembly if the ramps have beveled locking projections on the side facing the retaining element. In this embodiment, the guide element initially engages behind the lower part of the first bearing part. At the end of assembly, when pressure is applied to the assembly aid from the direction of the second bearing part, the ramps spread apart due to the beveled locking projections, thus overcoming the locking mechanism and allowing the sleeve to be pulled off the first bearing part.

[0020] According to an advantageous embodiment of the invention, the spreading of the ramps during assembly occurs automatically if an extension with a stop is arranged on the alignment element, the stop pressing against the bearing pin's bearing after assembly. Thus, during the assembly of the first bearing part to the second, the extension transmits force from the second bearing part to the assembly aid. This allows the assembly aid to be easily removed from the first bearing part after assembly.

[0021] According to another advantageous embodiment of the invention, the assembly aid can be manufactured particularly cost-effectively if the alignment element and the guide element are manufactured in one piece.

[0022] The invention allows for numerous embodiments. To further illustrate its basic principle, several of these are shown in the drawing and described below. This shows in Fig. 1 shows a window during the mounting of a sash to a frame using a mounting aid; Fig. 2 shows an enlarged view of the mounting aid. Figure 1 with adjacent areas of the frame and the sash, Fig. 3 greatly enlarged, the assembly aid made of Figure 1 In a perspective view, Fig. 4-7 shows further embodiments of the assembly aid. Figure 1 in perspective representations.

[0023] Figure 1 Figure 1 shows a window with a frame 1, a sash 2, and a lower hinge 3 designed as a corner hinge during installation. In the installed state, the sash 2 is also held by an upper scissor hinge 4 on the frame 1 and can be rotated about a vertical axis 5 relative to the frame 1 and tilted about a horizontal axis 6. The sash 2 is in a slightly tilted position and is aligned relative to the frame 1 during installation.

[0024] Figure 2The image shows an enlarged view of bearing 3, designed as a corner bearing, during the process. Figure 1 The assembly described above. The bearing 3, designed as a corner bearing, has a first, sash-fixed bearing part 7 and a second, frame-fixed bearing part 8. The frame-fixed bearing part 8 has a bearing bolt 9, which can be tilted about the horizontal axis 6 and has a bearing 27. During window assembly, this bearing bolt is inserted into a bearing band 10 of the second, sash-fixed bearing part 8. An assembly aid 11 according to the invention has an alignment element 12 detachably attached to the first bearing part 7 and a guide element 13 facing the free end of the bearing bolt 9 of the second bearing part 8. When the sash 2 is inserted into the frame 1, the guide element 13 guides the bearing bolt 9 into the bearing band 10. The bearing 3 is thereby assembled.

[0025] Figure 3 shows greatly enlarged images of the assembly aid Figure 2In a perspective view, it can be seen that the alignment element 12 has a C-shaped sleeve 14 in cross-section, which, in the assembled state, partially surrounds the bearing band 10 of the wing-side bearing part 7. Free ends of the C-shaped sleeve 14 form clamping lugs 20 for a holding device 19 for clamping the assembly aid 11 to the wing-side bearing part 7. The guide element 13 has a ramp 15 arranged on the end face of the sleeve 14. The ramp 15 is designed as an insertion funnel 16. Furthermore, the sleeve 14 has a ramp 17 that points radially inward into the movement area of ​​the bearing bolt. When the bearing bolt 9 encounters the ramp 17 during assembly, the assembly aid 11 is pushed laterally away from the wing-side bearing part 7. The ramp 17 can, for example, penetrate the bearing belt 10 via an opening not shown.Two ribs 18 project from the outside of the sleeve 14, one of which is visible in the illustrated perspective. The mounting aid 11 can be gripped via the ribs 18 or clamped in a profile groove (not shown) of the frame 1 or the sash 2. The mounting aid 11 is manufactured in one piece from plastic or metal, particularly by injection molding.

[0026] Figure 4 Figure 1 shows a further embodiment of an assembly aid 111 according to the invention, in which an alignment element 112 has a sleeve 114 with two clamping lugs 120 of a holding device 119. The clamping lugs 120 are spring-elastic and enable a clamping connection on the first bearing part 7 of the bearing 3. At the free end of the sleeve 114, a guide element 113 with a ramp 115 designed as an insertion funnel 116 is arranged. Otherwise, the assembly aid 111 is like the one shown in Figure 1. Figure 3 built.

[0027] Figure 5Figure 1 shows a further embodiment of an assembly aid 211 according to the invention with a holding device 219 having a locking element 221 for holding an alignment element 212 having a sleeve 214 on the first bearing part 7. A guide element 213 has a projecting ramp 215 for guiding the bearing bolt 9 of the second bearing part 8.

[0028] Figure 6 Figure 1 shows a further embodiment of an assembly aid 311 according to the invention, in which a sleeve 314 of an alignment element 312 has a holding device 319 with clamping lugs 320 for clamping with the first bearing part 7. A guide element 313 with a ramp 315 projects from an end face of the sleeve 314.

[0029] In Figure 7Another embodiment of an assembly aid 411 according to the invention is shown. In this embodiment, the guide element 412 has two separate ramps 421, 422, which allow them to bend elastically independently of one another. Both ramps 421, 422 each have a chamfered locking projection 423, 424. These locking projections 423, 424 engage behind the underside of the first bearing part 7 when the assembly aid 411 is attached to it. In addition, in this embodiment, the assembly aid 411 has a projection 425, which has a stop 426 at its end facing the second bearing part 8. The projection 425 is arranged on the alignment element 412. At the end of the assembly, the stop 426 presses against the bearing 27 of the bearing bolt 9, thereby exerting a force on the assembly aid 411 in the direction of the first bearing part 7.This force, combined with the chamfered locking projections 423, 424, releases the locking mechanism of these projections, allowing the assembly aid 411 to be removed from the first bearing part 7. The assembly aid 411 also features, as in other embodiments, a rib 418 which serves as a handle and a holding device 419.
