D - 41189 Mönchengladbach Hinge arrangement for doors, windows and the like

The invention relates to a belt arrangement of the type corresponding to the preamble of claim 1.

Such a hinge arrangement is described in DE-GM 296 02 084. The hinge of such a hinge arrangement is also referred to as a "concealed hinge" because it cannot be seen from the outside when the sash is closed, but is housed entirely inside the frame profiles. The known hinge is horizontally adjustable in order to be able to adjust the sash within the frame opening. In the known embodiment, adjustment is made from two surfaces that extend parallel to the frame plane, are provided with interlocking teeth and are flat overall, which can be connected to one another by screws that extend perpendicular to the frame surface. To adjust, these screws are loosened so that the surfaces that carry the teeth can be moved against one another.

The installation of such hinges is not easy, especially with heavy sashes, because the sashes have to be held in position by hand while the hinge parts are attached. The weight of the sash, however, makes maintaining the exact overlap of the fastening holes a difficult and laborious task.

The invention is therefore based on the object of designing a generic hinge arrangement in such a way that the installation of the sash in the fixed frame is facilitated.

This object is solved by the invention set out in claim 1.

Because the pivot lever engages with a tongue in a corresponding slot formed by at least one of the hinge parts, it is possible to transfer the weight of the leaf, which can be 100 kg or more in the case of door leaves, to the fixed frame immediately at the start of assembly by "hanging it in", without the leaf having to be held up for a longer period. Assembly can then be completed by tightening the fastening screws when the leaf is already hanging in the frame. This enables quick and safe assembly. In addition, the leaf is arranged in a form-fitting and correct position in relation to the frame as soon as it is hung in thanks to the hinge arrangement according to the invention.

The sash only needs to be held until the tongue engages in the slot, then the sash can be released. It now hangs under its full weight on the pivot lever or the frame. To complete the assembly, all you need to do is insert and tighten the fastening screws.

Since the tongue has a vertically extending thickening that is located approximately in the middle of the tongue and the slot has an area with an enlarged diameter to accommodate this thickening, the sash cannot be pulled out or slipped out or tipped over. This is an important safety factor when installing heavy sashes. In addition, the fact that the tongue engages in the slot in the sash hinge part prevents the sash from tipping over sideways.

The slot or its enlarged area is particularly easy to produce if the thickening has a bolt-shaped form.

Preferably, the thickening is horizontally adjustable in relation to the tongue, which allows the sash to be adjusted horizontally in relation to the frame. The adjustment is preferably carried out using an eccentric screw.

To make the slot in the hinge part of the sash particularly cheap and easy to produce, for example by milling, the slot is open at the top and bottom and can be closed in the enlarged area using threaded screws. This prevents the tongue from slipping through the slot when the sash is hung.

With modern doors and hinges, vertical adjustment of the leaf relative to the frame is also desired. It is therefore advantageous if the tongue can be adjusted vertically in the slot, which allows the leaf to be adjusted relative to the frame. The vertical adjustment of the tongue is advantageously carried out using the threaded screws to close the enlarged area of the slot.

Further details, features and advantages of the present invention will become apparent from the description of the drawings. They show:

Fig. 1 is a perspective view of a hinge arrangement according to the invention on a section of the frame profiles of the fixed frame and the sash before hanging, with hidden lines partially shown in dashed lines;

Fig. 2 a view corresponding to Fig. 1 after hanging the sash and

Fig. 3 an exploded view of the sash hinge part with the pivot lever.

In Fig. 1 and Fig. 2, the hinge arrangement according to the invention is designated with 100. It serves for the pivotable mounting of a sash F _1, of which only a vertical section of a sash frame profile 20 is visible, on a correspondingly shown frame profile 10 of a fixed frame R. The frame profiles 10, 20 of the sash F or of the fixed frame R are designed as hollow profiles. A hinge bolt (not visible in the figures) is fixedly attached inside the frame profile 10, which determines a hinge axis about which the sash F can be pivoted open.

The frame profile of the fixed frame R has an approximately rectangular cross-section and consists of a first hollow profile 1 with a rectangular cross-section, which is connected to a further hollow profile 3 on the inside underneath by heat-insulating webs 2 running in the longitudinal direction near the lateral boundary. The parts 1, 2, 3 form the frame profile 10 as a structural unit. In a corresponding manner, the sash frame profile 20, which is also essentially rectangular in cross-section, is formed by a rectangular hollow profile 11, which is connected to a rectangular hollow profile 13 by heat-insulating webs 12. In the exemplary embodiment, the frame profiles 10, 20 lie essentially in one plane when the sash F is closed, with the front and rear boundary surfaces each being located in the same plane.

A rebate area 40 remains between the frame profiles 10, 20, which is covered by rebate parts 14 of the rectangular profile 3 or 24 of the rectangular profile 11 provided with seals 6, so that the rebate area 40 is in turn closed when the sash F is closed. The actual hinge is housed entirely inside the frame profiles 10, 20, so that it cannot be seen from the outside when the sash F is closed.

The hinge bolt is arranged near the outer wall of the frame profile 10. Its support, which can be seen in the drawing, is the frame hinge part 60. The frame hinge part consists of a carrier plate 61 which is fastened to the wall 4, which faces the rebate area 40, by means of screws 62 and spacer bushes 63 and which engages in a corresponding recess 64. When closing the sash F, the recess 64 provides sufficient space so that the sash hinge part, which is designated as a whole with 50, can be pivoted into the frame profile 10 around the hinge bolt.

The sash hinge part 50 comprises a pivot lever 51 which can pivot around the hinge bolt and which forms a tongue 73 on its side remote from the hinge bolt, which extends approximately centrally through a vertically extending bolt 59. The bolt 59 thus forms a thickened area of the tongue. An eccentric screw 58 is provided for adjusting the bolt relative to the tongue or the pivot lever. This makes it possible to adjust the bolt 59 horizontally relative to the pivot lever 51 and thus to effect a horizontal adjustment of the sash F relative to the frame R.

The sash hinge part 50 further comprises a fastening rail 52 which is fastened by means of screws 56 in bores 75 on the sash frame profile 20 on the wall facing the rebate area 40. The fastening rail 52 forms a slot 53 running vertically in the plane of the sash, which has a region 54 which also runs vertically and is enlarged in diameter, approximately in the middle, and which in the exemplary embodiment has a circular cross-section adapted to the bolt 59. Threaded screws 74 can be screwed into the threads present on the top and bottom of the region 54 which is enlarged in diameter. The upper threaded screw 74 serves as a stop for the bolt 59 when the sash F is hung in. The sash is then locked in place and secured against being lifted out by means of the lower threaded screw 74. In order to ensure a further force-locking connection of the pivot lever 51 or its tongue 73

In order to achieve a perfect connection with the sash hinge part 50 or the fastening rail 52, screws 71 and corresponding threaded holes 72 are provided for clamping the tongue 73 in the slot 53 of the fastening rail 52.
.

Fig. 1 shows the state before the sash F is hung on the frame R. In contrast, in Fig. 2 the sash F is already hung and fastened to the frame R. To hang the sash F is pushed onto the bolt 59 and the tongue 73 of the pivot lever 51 by means of the fastening rail 52 or the slot 53 and the associated enlarged diameter area 54. For this purpose, as already mentioned above, the upper threaded screw 74 is screwed in as an upper stop and prevents the tongue 73 from slipping through. To ensure that the pivot lever 51 does not pivot into the recess 64 in the frame profile 10 during this process and thus make it difficult to hang the sash F, the latter is secured by means of a suitable device such as a spring that urges the pivot lever 51 in the open direction. After the sash F has been hung, its entire weight rests on the pivot lever 51 and cannot slip off the frame hinge part due to the enlarged diameter of the bolt 59, which rests in the enlarged diameter area 54 of the slot 53. This ensures quick and safe assembly without the sash F having to be held for a long time with its high weight and tipping sideways or in the sash plane.

For the final fastening of the sash F, the lower threaded screw 74 is screwed into the enlarged area 54 of the slot 53 after hanging, thus making it impossible to lift off the sash F. The screws 71 also clamp and fasten the tongue 73 of the pivot lever 51 in the slot 53.

As mentioned, the bolt 59 and thus the sash F can be adjusted horizontally relative to the frame. To do this, the eccentric screw 58,

which engages in an oval recess 78 in the tongue 73 of the pivot lever 51.

A vertical adjustment of the sash F relative to the frame is also possible. To do this, the lower threaded screw 74 in the enlarged area 54 of the slot 53 is loosened and the sash F is adjusted to the desired height using the upper threaded screw 74. The lower threaded screw 74 is then screwed in again.

To ensure that the eccentric screw 58 remains accessible during both vertical and horizontal adjustment of the sash F, a corresponding oval recess 55 is provided in the fastening rail 52. To ensure that the fastening screws 71 do not impair the vertical and/or horizontal adjustment of the sash F, correspondingly large rectangular recesses 65 are provided in the pivot lever 51 through which the screws penetrate the pivot lever. This means that adjustment can be carried out despite the screws 71 being screwed in.

From Fig. 3 it can be seen that the bolt 59 is pushed onto the tongue 73 of the pivot lever 51, for which purpose corresponding recesses 77 are provided in the bolt 59. The eccentric screw 58 is then inserted into the recess 78 and again clamped with a cover plate 76. The cover plate 76 can be made of an elastically deformable material. It is also conceivable that the cover plate 76 then has a slight, outward-directed curvature, which is squeezed when the bolt 59 is inserted into the slot 53 and thus ensures that the bolt 59 is firmly seated.
