Description

The invention relates to a mounting device for holding mounting rails during assembly of the mounting rails on a suspended wall or ceiling.

Conventionally, recessed lights for suspended ceilings and walls are attached directly to a section of the suspended ceiling or wall. The drywall builder first has to prepare a section in which the electrician then installs the luminaire. Then the drywall builder has to plaster the luminaire flush with the surface again. This solution is not only expensive, since the two trades must interlock, but also tends to cracking.

This is how the document shows WO 2014/020015 A1 such a mounting system. The document US 5045985 discloses a mounting device according to the preamble of claim 1.

To overcome the difficulties mentioned above, a novel mounting system for the thermally decoupled assembly of luminaires has been developed. The novel mounting system uses mounting rails, which are mounted at a defined distance to a cutout in a suspended ceiling or wall. The receiving rails are preferably plastered to a plastering edge. The electrician can now place luminaires directly in the prepared mounting rails without the help of the drywall builder. Another rework by the drywall is not necessary. Also, there is a good thermal separation of the lamp from the suspended wall or ceiling, as between the receiving rails and the edge of the cutout can remain a distance.

However, the mounting of the mounting rails is so far very complex, since an exactly parallel course at a defined distance in the correct orientation is necessary to install the lights, which can be from different manufacturers, easily installed. So far, it is thus necessary that the drywall uses the mounting rails with a very high precision and connects to the suspended ceiling or wall. This requires a high amount of work time and at the same time tends to cause errors that make subsequent assembly of the lights impossible.

The invention is therefore an object of the invention to provide a mounting device, which allows a simple and time-saving installation of the mounting rails.

The object is achieved for the device by the features of the independent claims. Advantageous developments are the subject of the dependent claims.

A mounting device according to the invention for mounting receiving rails for light housings on cut-outs of suspended walls or ceilings includes a substantially rigid frame and connected thereto a first receptacle for holding a first receiving rail, and a second receptacle for holding a second receiving rail. The receptacles are designed to hold the receiving rails parallel to each other and to keep them at a defined distance from each other. This ensures that during installation of the mounting rails, the drywall does not have to pay attention to the parallelism of the mounting rails and the distance of the mounting rails. A very simple and quick installation of the mounting rails is achieved.

Preferably, the receptacles are designed to hold the receiving rail individually and / or jointly releasably, preferably one-handed releasable. This ensures that the assembly is further simplified.

Additionally or alternatively, the receptacles are designed to hold the receiving rails in the longitudinal direction relative to the mounting device displaceable. It is thus achieved that with very high precision, the mutual arrangement of the receiving rails can be adjusted in the longitudinal direction.

Additionally or alternatively, the receptacles are designed to hold the receiving rails in a defined orientation about their respective longitudinal axis to each other. A particularly reliable orientation of the receiving rails is thus achieved.

Preferably, the mounting device for mounting of substantially L-shaped receiving rails is formed, each having a first leg for mounting on a bottom of the suspended ceiling or a front of the suspended wall and a second leg for engagement in the cutout and for supporting the lamp housing , In this case, the shots designed to hold the receiving rails such that the first legs extend in a plane, and the second legs are parallel. This ensures that the mounting rails can be mounted very easily and later the luminaire housing can be very easily used.

Preferably, the receptacles each have a first guide profiling for receiving a first profiling of the respective receiving rail, preferably for receiving the profiling of the second leg of the receiving rails. The first guide profiling can be flexible or resilient and in particular connected via resilient arms with the rigid frame. A particularly secure mounting of the mounting rails by the mounting device is thus guaranteed. In addition, the guide profiling can be easily snapped into the profiling of the mounting rail.

Preferably, the receptacles each have a second guide profiling for receiving a second profiling of the respective receiving rail, preferably for receiving a Einputzkante the receiving rails. The second guide profilings are preferably rigid and, in particular, integral with the rigid frame, preferably in wings extending laterally away from the frame. The wings can also be preferably designed such that they are in the receiving rail inserted in flat contact with the receiving rail, in particular with the first legs of the same. A further improvement of the mounting security is achieved. In addition, a predetermined distance between two receiving rails is ensured by the corresponding elements and due to the rigid frame in a simple manner. In particular in connection with the preferably flexibly provided first guide profiling can / can thus easily clamped the receiving rail (s) between the two recordings and thus be aligned in a predetermined manner. For this purpose, the first guide profilings are preferably substantially opposite the second guide profilings and are facing one another in order to be able to clamp the receiving rails therebetween by means of the guide profilings. The guide profiles are designed such that they serve as a guide for sliding along the mounting device in the longitudinal direction of the receiving rails together with the corresponding elements on the side of the receiving rails.

The mounting device may further comprise a handle for holding the mounting device, which is preferably connected to the rigid frame. According to one embodiment, this handle can be connected by means of resilient legs directly to the frame or via the first guide profiles to the rigid frame. In the latter case, it is further made possible to operate the first guide profiling by means of the handle, ie to insert or remove the mounting device to pivot the first guide elements inwards (toward each other) and thus expose.

Preferably, the receptacles are designed to simultaneously hold two mutually longitudinally adjoining receiving rails in alignment with each other. In particular, when mounting a plurality of adjoining receiving rails in a common section of the suspended ceiling or suspended wall thus a particularly high alignment accuracy is achieved.

Preferably, the receptacles are designed to each receive a not yet mounted on the suspended ceiling or suspended wall receiving rail, and mounted on a already mounted on the suspended ceiling or suspended wall receiving rail and not yet mounted on the suspended ceiling or suspended wall Recording rail to record. So the drywall can choose between two different mounting options. In the first possibility, it first connects both mounting rails with the mounting device and uses the so-connected mounting rails in the cutout of the suspended wall or ceiling, to then connect them to the suspended wall or suspended ceiling. In the second alternative, the drywaller first installs one of the mounting rails on the suspended wall or suspended ceiling in the region of the cutout and then inserts the mounting device into the already mounted mounting rail. Another receiving rail is then inserted into the second receptacle of the mounting device. This second receiving rail can now be connected to the suspended wall or suspended ceiling. A particularly great flexibility of the assembly is achieved.

Preferably, the mounting device is made in one piece. Additionally or alternatively, the mounting device is manufactured as a stamped sheet metal or as a metal injection molded part or as a plastic injection molded part. Thus, a particularly simple and cost-saving production is achieved.

The mounting device according to the invention is particularly advantageous because the precise positioning of a concern of the second leg of the receiving rails at the edges of the respective section is not necessary. A particularly good thermal separation of the receiving rails from the edges of the suspended ceiling or edge can be achieved.

An inventive mounting system has a previously described mounting device and at least two receiving rails. A particularly simple mounting of the mounting rails and subsequent recording of lights is guaranteed.

The mounting system preferably has a first mounting device described above and a second mounting device described above and at least two mounting rails. The first mounting device and the second mounting device are designed to simultaneously hold the mounting rails at different positions (eg one end of the mounting rails) and to be displaceable along the longitudinal direction of the mounting rails. This ensures that a particularly accurate alignment and positioning of the mounting rails is achieved.

Based on Figures 1-3 will be described in detail below on the structure and operation of various embodiments of the invention Received mounting device. Identical elements have not been repeatedly shown and described in similar figures.

In Fig. 1 is a first embodiment of the mounting device 1 for mounting receiving rails 4a, 4b shown. Shown here is an assembly of the receiving rails 4a, 4b on a suspended ceiling. Of course, an identical installation on a suspended wall is also possible. The mounting rails 4a, 4b are attached to the lateral edges of a cutout 3 of the suspended ceiling and delimit the cutout 3 from.

Each of the two receiving rails 4a, 4b has a first leg 5a, 5b which is fastened to the suspended ceiling parallel to the underside of the suspended ceiling. In addition, each receiving rail 4a, 4b has a second leg 6a, 6b, which is arranged at a 90 ° angle relative to the first leg 5a, 5b and engages in the cutout 3. The second legs 6a, 6b are intended to carry the light housing to be mounted in the cutout 3.

The receiving rails 4a, 4b continue to have on-plaster edges 8a, 8b, which separate the first leg 5a, 5b of the second leg 6a, 6b. The Einputzkanten 8a, 8b are used for flush with the underside of the suspended ceiling plastering the receiving rails 4a, 4b.

In addition, in Fig. 1 an embodiment of the mounting device 1 according to the invention shown. The mounting device 1 has receptacles 2a, 2b, which serve to hold the receiving rails 4a, 4b. The receiving rails 4a, 4b are held by the receptacles 2a, 2b of the mounting device 1 parallel to each other and at a defined distance. It is thus very easy to mount the receiving rails 4a, 4b at the edges of the cutout 3 while being held by the mounting device 1 in the correct position and orientation.

In particular, the receiving rails 4a, 4b are held by the receptacles 2a, 2b in a defined orientation about their respective longitudinal axis to each other. That is, the receiving rails 4a, 4b are held so that their respective second legs 6a, 6b engage in cutout 3, while their respective first legs 5a, 5b in parallel with the underside of the suspended ceiling.

Preferably, the receiving rails 4a, 4b by the recordings 2a, 2b thereby individually or jointly releasably, in particular one hand releasably held. It is thus achieved that the installer can easily or jointly connect the receiving rails 4a, 4b with the mounting device 1 and also separate them from the mounting device 1 again. In particular, the one-handed solubility facilitates the workflow clearly, as the second hand of the fitter is thus available for tool use.

The receptacles 2a, 2b each have a first guide profiling 12a, 12b, which is designed to engage in profiles of the second legs 6a, 6b of the receiving rails 4a, 4b and thus to hold them. The first guide profiling 12a, 12b is for this purpose preferably flexible or resilient provided by, for example. Via resilient arms 16a, 16b, 17a, 17b (see Fig. 3 ) is connected to the rigid frame 15 of the mounting device 1. In addition, the receptacles 2a, 2b have second guide profiles 10a, 10b, 11a, 11b, which serve to receive the plastering edge 8a, 8b of the receiving rails 4a, 4b. The second guide profiling 10a, 10b, 11a, 11b is for this purpose preferably rigidly provided, for example, in that the wings 18a, 18b (see FIG. 1) extending, for example, integrally with the rigid frame 15, extend laterally away from the frame 15 FIG. 2 ) are provided. The wings 18a, 18b are designed such that, when the receiving rail 4a, 4b is inserted, they are in planar contact with the receiving rail 4a, 4b or the first legs 5a, 5b thereof. The second guide profiles 10a, 10b, 11a, 11b are present twice in each receptacle 2a, 2b in the embodiment shown here. The guide profiles 10a, 10b, 11a, 11b, 12a, 12b are all designed so that they serve as a guide for sliding along the mounting device 1 in the longitudinal direction of the receiving rails 4a, 4b together with the corresponding elements on the side of the receiving rails 4a, 4b. The first guide profiles 12a, 12b are substantially opposite the second guide profiles 10a, 10b, 11a, 11b and face each other. By means of the guide profiles 10a, 10b, 11a, 11b, 12a, 12b, the receiving rails 4a, 4b can thus be clamped therebetween.

By the holder of the receiving rails 4a, 4b by the guide profiles 10a, 10b, 11a, 11b, 12a, 12b of the receptacles 2a, 2b of the mounting device 1 is a secure, easily detachable and largely stable mounting of the receiving rails 4a, 4b ensured during the assembly process.

If a particularly long cutout 3 is to be provided with receiving rails 4a, 4b with the aid of the mounting device according to the invention, it may be necessary to subsequently attach several receiving rails 4a, 4b in the longitudinal direction. In this case, the mounting device 1 is designed to hold two receiving rails 4a, 4b and thus four receiving rails 4a, 4b directly next to each other with each receptacle 2a, 2b. Thus, a particularly large alignment accuracy at the point of change of adjacent receiving rails 4a, 4b guaranteed.

For mounting the receiving rails 4a, 4b, the fitter has several options. On the one hand, he can connect two not yet mounted receiving rails 4a, 4b with the receptacles 2a, 2b of the mounting device 1 and insert the thus connected receiving rails 4a, 4b together in the cutout 3. He can now connect both mounting rails simultaneously with the edges of the section 3.

Alternatively, the fitter can connect a receiving rail 4a, 4b to an edge of the cutout 3 and then connect the already mounted receiving rail 4a, 4b to the mounting device 1 and by means of this with a not yet mounted receiving rail 4a, 4b.

The mounting device 1 is preferably designed to be operated with one hand. For this purpose, the mounting device 1 has a handle 14, which is preferably connected to the frame 15 and for holding the mounting device 1 and thus also the connected receiving rails 4a, 4b, is used. In a preferred embodiment, which is also shown in the figures, the handle 14 is connected to the frame 15 by means of resilient legs 13a, 13b via the first guide profilings 12a, 12b. In this case, the handle 14 preferably also serve to release and connect the receiving rails 4a, 4b with the receptacles 2a, 2b. By compressing each connected to one of the opposing first legs 12a, 12b two legs 13a, 13b of the handle 14, the guide profiles 12a, 12b of the profiles 7a, 7b of the second leg 6a, 6b of the receiving rails 4a, 4b pushed away and towards the second guide profiles 10a, 10b, 11a, 11b exposed, whereby the receiving rails 4a, 4b no longer sit firmly in the receptacles 2a, 2b.

Preferably, in the connected state, the receiving rails 4a, 4b in the receptacles 2a, 2b are longitudinally displaceable. Thus, a particularly simple adjustment of the position along the edges of the cutout 3 can be achieved.

An inventive mounting system includes at least one mounting device 1 and at least two receiving rails 4a, 4b. Alternatively, however, the mounting system can also have a plurality of mounting devices 1. This is particularly useful for very long receiving rails 4a, 4b, since with very long receiving rails 4a, 4b strong shearing forces on the receptacles 2a, 2b may arise. A more stable and above all torsionally rigid attachment of the receiving rails 4a, 4b can be achieved in this way.

Alternatively, in a mounting system with only one mounting device 1 for mounting the receiving rails 4a, 4b proceed so that the mounting device 1 is first attached to a common end of the two receiving rails 4a, 4b. The receiving rails 4a, 4b are then fastened with this end to the edges of the cutout 3. The mounting device 1 is now moved along the length of the receiving rails 4a, 4b. This automatically sets a parallel and correctly arranged course of the receiving rails 4a, 4b. At regular intervals, the receiving rails 4a, 4b can now be connected to the edges of the cutout 3. Thus, even very long mounting rails can be processed correctly with only one mounting device 1.

The guide profiles 12a, 12b are preferably formed integrally with the frame 15 of the mounting device 1. They are preferably connected to each other by a connecting web on the side facing away from the suspended wall or ceiling of the mounting device 1. As a result, a one-handed assembly and in particular a one-handed release and connecting the receiving rails 4a, 4b with the mounting device 1 allows. In the embodiment illustrated here, the connecting web is part of the handle 14.

After assembly of the receiving rails 4a, 4b on the suspended ceiling or the suspended wall in the region of the cutout 3, the mounting device can. 1 be removed by releasing the recordings 2a, 2b. Subsequently, the receiving rails 4a, 4b along the Einputzkanten 8a, 8b are plastered. The trade of drywaller is completed. A subsequent rework after installation of the lights is not necessary.

In Fig. 2 is a side view of in Fig. 1 shown mounting device 1 shown. In Fig. 3 is a top view of the in Fig. 1 and Fig. 2 shown mounting device 1 shown.

The invention is not limited to the illustrated embodiment. In particular, by means of the mounting rails deviating components may also be mounted. A use of more than two mounting devices is conceivable. In particular, a delivery of the receiving rails in the connected state with one or more mounting devices is conceivable. All features described above or features shown in the figures can be combined with each other in any advantageous manner within the scope of the invention.
