- 1 Description

The invention relates to a kit for a coffered ceiling, with support rails and ceiling panels arranged one behind the other in the longitudinal direction of the rails and pivotably mounted, whereby the ceiling panels each have a pivot bearing element and a locking element on both sides and these elements interact with the support rails.

In this type of cassette ceiling, the ceiling panels are preferably hinged or collapsible downwards in order to be able to inspect supply lines laid above the cassette ceiling and to carry out maintenance work. In a known embodiment, brackets are pivotally mounted on both sides of the ceiling panels, the bent ends of which overlap the support rails. In addition, the ceiling panels have spring-loaded latches on both sides, which are pivotally mounted on the ceiling panels and can be brought into engagement with the support rails. This known construction is relatively complex in terms of production and assembly technology. The invention aims to remedy this.

The invention is based on the object of creating a kit for a coffered ceiling of the type described at the beginning, in which the pivoting and locking elements for », the foldable ceiling panels for keeping the top of the ceiling panels free for additional components , e.g. sound and fire protection, are arranged within the ceiling panels and are designed to be simple and reliable in terms of production and assembly technology, but also in terms of storage.

The invention solves this problem in a generic kit in that the pivot bearing elements and ^locking elements are designed as spring-loaded pivot bearing bolts and locking bolts, _that the pivot bearing bolts and locking bolts arranged within the ceiling panel penetrate the associated web side of edge closure profiles of the support rails and that the respective edge closure profile has recesses in its web side, and that at least the locking bolts for pivoting the ceiling panels up or down can be easily pushed back from their locking position into a release position against the action of a spring. - These measures of the invention result in the pivot bearing elements and locking elements being designed as identical bolts. This is just as advantageous in terms of production technology as it is in terms of storage. In addition, the installation of ceiling panels with spring-loaded pivot bearing and locking bolts on both sides is relatively simple and can be carried out quickly, because the pivot bearing and locking bolts only have to be pushed back into the release position in order to then automatically engage in the bearing recesses of the edge connection profiles as a result of their spring loading. In addition, a rotating bearing of the pivot bearing bolts in the ceiling panels is not necessary, rather the pivot bearing for swiveling up or down or folding down the ceiling panels is formed by the pivot bearing bolts and the bearing recesses in the edge connection profiles.

Further features essential to the invention are listed below. The invention provides that the pivot bearing bolts and the pre-pinning bolts in U-shaped bearing blocks of the

This ensures perfect and stable mounting of the swivel bearing and locking bolts in the ceiling panels. The invention also teaches that the swivel bearing and locking bolts have a circumferential interrupted or uninterrupted bearing groove on their bolt ends engaging in the edge profiles for fixing the bolt ends in the bearing recesses. Fixing means that a forced positioning of the pivot bearing and locking bolts in the bearing recesses of the edge connection profiles is achieved and at the same time independent loosening or unlocking is excluded. This applies in particular if the bearing recesses in the area of the pivot point are designed to match the I.'T groove in the pivot bearing bolt or at least the locking bolts have a collar-forming locking ring or molded collar behind the bearing recesses on their engaging bolt ends. The invention also recommends that the bearing recesses each have a hole for inserting the bolt ends through, if necessary with their collar or locking ring, and an L-shaped slot adjoining the hole, the width of which is less than the bolt diameter and corresponds to the bolt constriction in the area of the bearing groove. This achieves a bayonet-like locking of the pivot bearing and locking bolts in the edge connection profiles. The bearing blocks or pivot bearing bolts and locking bolts are preferably located in the outer corner areas on the underside of the ceiling

plates in order to achieve a trouble-free pivoting away from the ceiling panels and to maintain a predetermined gap-like distance between the individual ceiling panels. In addition, the locking bolts for pushing them back into the release position are easier to access if they are arranged in the lower area of the ceiling panels. - The support rails each have a U-shaped wall connection pin _and telescopic brackets inserted into the continuous wall connection profile at predetermined intervals, with the continuous edge connection profiles § connected to the telescopic brackets. With the help of the telescopic brackets, the distance of the edge connection profiles from the respective building wall can be varied and adjusted to the required system dimensions of the wall panels and thus to the penetration depth of the pivot bearing or locking bolts of the ceiling panels. For this purpose, the telescopic brackets preferably consist of profile halves that can be adjusted between the wall side and the narrow side of the ceiling panels designed ^as long field panels, e.g. U-shaped or box-shaped profile halves with a locking screw in the middle of ^the long hole ^guide , so that only the loosening and tightening of a single screw is required in order to be able to adjust and lock a telescopic bracket to the required distance. Particularly long ceiling panels can be divided transversely to avoid bending. In such a case ^, the invention provides that a U-shaped or C-shaped bandraster profile is arranged between the transversely divided ceiling panels and that the ceiling panels in the division area also have spring-loaded pivot bearing bolts and locking bolts, which engage in corresponding bearing recesses in the U-legs of the bandraster profile.

fils with a bearing recess for a pivot bearing or locking bolt in the engagement direction.

The figures show a kit for a cassette ceiling, in particular for an externally insulating ceiling. Each kit has support rails 2 to be connected to a building wall 1 on both sides and ceiling panels 3 arranged one behind the other between the support rails 2 in the longitudinal direction of the rails at a predetermined distance and pivotably mounted, which are designed as long-span panels. The ceiling panels 3 have a pivot bearing element 4 and a locking element 5 on both sides. These elements 4, 5 interact with the support rails 2. The pivot bearing elements and locking elements are designed as spring-loaded pivot bearing bolts 4 and locking bolts 5. The pivot bearing bolts

4 and locking bolts 5 penetrate the associated web side 6 of edge profiles 7 of the support rails 2. For this purpose, each edge profile 7 has bearing recesses 8 in its web side 6 for the pivot bearing bolts 4 and locking bolts 5. At least the locking bolts 5 can be pushed back against spring action from their locking position engaging in the edge profiles 7 into a free position in order to pivot or swing the ceiling panels 3 up or down or fold them down. The pivot bearing bolts 4 and locking bolts

5 are mounted in U-shaped bearing blocks 9 and are surrounded between the U-legs 10 of the bearing blocks 9 by a helical spring 11, which is supported on the one hand against one U-leg 10, and on the other hand against a collar-forming locking ring 12 on the pivot bearing or locking bolt 4, 5.

Furthermore, the pivot bearing bolts 4 and locking bolts 5 have a circumferential, interrupted bearing groove 13 on their bolt ends engaging in the edge profiles 7 for fixing the bolt ends in the bearing recesses 8. At least the pivot bearing bolts 4 can have a collar-forming locking ring 14 behind the bearing recesses 8 on their engaging bolt ends. The bearing recesses 8 f each have a bore 15 for inserting the bolt ends through, and an L-shaped slot 16 adjoining the bore 15, the width of which is less than the bolt diameter and corresponds to the bolt constriction in the area of the bearing groove 13. The bearing blocks 9 or pivot bearing bolts 4 and locking bolts 5 are arranged here in the outer corner areas on the underside of the ceiling panels 3.

The support rails 2 each have a U-shaped wall connection profile 17 and telescopic brackets 18 inserted at predetermined intervals in the continuous wall connection profile 17. The edge finishing profiles 7, which also run through, are connected _to the telescopic brackets 18. The telescopic brackets 18 consist of profile halves arranged between the wall connection profile and the band connection profile 7 or the wall side and the narrow side of the ceiling panels 3, J designed as long-span panels, e.g. U-shaped or box-shaped profile halves with a centrally located slotted hole for a locking screw 19.

In the case of ceiling panels 3 which are designed to avoid excessively large diameters, the distance between the ceiling panels 3 and the profile r is 1 20 mm.
