Description

The invention relates to a multi-purpose hanger for profile rails, in particular the support rails of suspended suspended ceiling, according to the preamble of claim 1.

Rectangular rails made of sheet metal are used in the construction of suspended ceilings as wide span beams that support the supporting structure of the suspended ceiling. This support structure consists, for example, of upwardly open, C-shaped profile rails made of sheet metal.

For the connection of these parts of a false ceiling and / or for the suspension from the structural ceiling different hangers are used, the parts engaging with the C-rails are generally designed so that they are either anchored in the C-rails or have locking notches on the opposite edges of a sheet metal leg, in which the mutually angled edges of the C-rails engage. Such hangers are previously known from FR-A-2 683 566.

The variety of hangers caused by the different connection and suspension options means, on the one hand, increased manufacturing effort; on the other hand, the different hangers must also be kept ready on the construction site.

The object of the invention is therefore to provide a multi-purpose hanger that can be used with a simple structure and simple manufacturing options for the different tasks that result in suspended ceilings when using C-shaped rails and box-shaped closed rails.

This object is achieved by the features of claim 1.

In its assembled form, the hanger consisting of the U-shaped support part and the associated counterpart forms in this assembled form a closed, essentially rectangular frame which encompasses the profile rail to be suspended, for example a box-shaped wide span beam, without any operations on this profile rail, such as holes or the like, would be required. The profile rail is longitudinally displaceable in the frame thus formed, so that easy alignment is made possible during the assembly process.

Since the U-shaped support part is only connected to the counterpart during assembly and these two parts can also be detached during assembly, subsequent attachment or another change during assembly is possible without difficulty.

Since the counterpart with its holding legs angled from the base plate and the locking strips projecting therefrom has the same cross-sectional profile as a C profile rail, the free ends of the U legs of the supporting part are designed in such a way that they can be optionally equipped with such a counterpart or a C- Profile rail can be connected. This measure makes it possible to use the U-shaped support part alone, ie without the counterpart, as a hanger for an upwardly open C profile rail, the free ends being snapped into the C profile rail in a manner known per se. The U-shaped support part can then either be attached to a suspension element via its web plate and suspended from the structural shell, or the U-shaped support part can grip over a wide span support and with its U legs hang a C-shaped rail from this wide span support.

The design of the U-shaped support part and the counterpart makes it possible to manufacture these parts from sheet metal in relatively simple manufacturing processes, with a sufficiently high load-bearing capacity also being obtained when using relatively thin sheet metal. On the one hand, this is due to the fact that the multi-purpose hanger in the assembled state forms a closed frame in which only slight bending forces occur even under high loads. On the other hand, the angled stop legs on the counterpart, which with the free ends of the U-shaped support part, effectively prevent unintentional unhooking of the U-legs of the support part on the counterpart.

Advantageous refinements of the inventive concept are the subject of dependent claims.

Exemplary embodiments of the invention are illustrated below, which are shown in the drawing. It shows in spatial representation:

• 1 shows the two parts of a multi-purpose hanger for rails in an exploded state,
• 2 shows the use of the multi-purpose hanger according to FIG. 1 for suspending a wide span beam of a suspended ceiling which is box-shaped in cross section,
• Fig. 3 shows the use of the U-shaped support part of the hanger according to Fig. 1 for hanging a C-rail from a wide span and
• Fig. 4 shows the use of the U-shaped support part of the multi-purpose hanger according to Fig. 1 for connecting a C-profile rail to a vibration suspension element.

The multi-purpose hanger shown in the drawing has a U-shaped support part 1 made of sheet metal (Fig. 1). A lower, approximately square web plate 2 is connected at its two mutually opposite edges 3 to an elongated U-leg 4, which is angled upwards at right angles and runs parallel and at a distance from one another.

The upper, free ends 5 of the U-legs 4 in the arrangement according to FIG. 1 each have a notch 6 at their mutually opposite edges. The dimensions of these free ends 5 of the U-legs 4 and in particular the notches 6 are measured so that they are suitable for connection to a conventional C-profile rail 7, as shown in FIGS. 3 and 4.

A mating piece 8 (FIG. 1) which can be connected to the free ends 5 of the U-legs 4 is also made of sheet metal and has an approximately square base plate 9, from each of which a short holding leg 11 is angled at two opposite edges 10. In the embodiment shown as an exemplary embodiment, each holding leg 11 is divided by a central incision 12.

From the free ends of the holding legs 11, angled latching strips 14 project from one another, which are intended to engage in the notches 6 when the support part 1 is connected to the counterpart 8 in the manner shown in FIG. 2.

On the two other edges 15 of the base plate 9, which run at right angles to the first-mentioned edges 10, a stop leg 16 is angled in each case, which in the assembled state (FIG. 2) each has the free end 5 of the associated U-leg 4 abuts, preferably from the outside. The connection between the support part 1 and the counterpart 8 is preferably made in such a way that the two free ends 5 of the U-legs 4 are pressed together and inserted into the counterpart 8 through the recesses 12. Then the U-legs 4 are released and spring outwards, so that their notches 6 snap into the latching strips 14.

The free ends 5 of the U-legs 4 and the abutting legs 16 of the counterpart 8 lying thereon are provided with congruent screw or rivet holes 17 and 18, respectively, so that the supporting part 1 with the counterpart 8 in the assembled state additionally by (not shown) Screws or rivets connected and can thus be additionally secured.

To increase the rigidity of the multi-purpose hanger even when using relatively thin sheet metal are in the illustrated embodiment on the bending edges 3 between the web plate 2 and the U-legs 4, on the bending edge 10 between the base plate 9 and the holding legs 11, to the Bending edges 13 between the holding legs 11 and the locking strips 14 and on the bending edges 15 between the base plate and the stop legs 16 beads 19 are provided, which are each perpendicular to these bending edges 3, 10, 13, 15 and extend into the two adjacent sheet metal surfaces . These beads 19 are preferably formed in a projecting manner inwards and are designed such that they also run continuously in the area of the respective bending edge 3, 10, 13 and 15.

In the U-legs 4 of the support member 1 two spaced and largely parallel beads 20 are formed, which also contribute to the fact that the support member 1 despite the use of relatively thin sheet has sufficient torsional rigidity. These two beads 20 run at the free end 5 of the U-leg 4 diverging and approximating to the rounded corners of the free ends 5. On the one hand, this creates sufficient space for the stop leg 16 to be created, on the other hand, the free ends 5 become precisely in the more heavily loaded area in the Neighboring the notches 6 additionally stiffened.

Beads 21, which are approximately diagonally formed in the base plate 9 of the counterpart 8, also serve as additional stiffening.

Fig. 2 shows the use of the support member 1 and the counterpart 8 to form a closed frame, in which a wide span support 22 is inserted with a box-shaped cross section. The counterpart 8 has in its base plate 9 a connection opening 23 into which, for example, a hanger rod 24, indicated only by dash-dotted lines, engages, with which the counterpart 8 is suspended from a structural ceiling.

In the example of use shown in FIG. 3, only the supporting part 1 of the multi-purpose hanger is used to hang a C-shaped rail 7 from a wide span support 22. For this purpose, the reversely deformed support part 1 reaches over the wide span support 22; its downwardly projecting U-legs 4 engage in the upwardly open C-profile rail 7, their mutually projecting locking strips 25 engaging in the locking incisions 6 at the free ends 5 of the U-legs 4.

In the same way, the U-shaped support part 1 shown in FIG. 4 is snapped onto the C-profile rail 7 shown there. Here, a suspension element, for example a vibration suspension element 26, engages in a connection opening 27 in the web plate 2 of the supporting part 1.
