Description

The present invention relates to a cladding system with a heating and/or cooling device.

ES 2 331 674 A1 discloses climate profiles as extruded aluminum profiles with a recess for receiving climate pipes, which are inserted via a substructure in a suspended heating and/or cooling ceiling. An additional closure is provided to fix the air conditioning pipes in these recesses.

From the DE 20 2010 011 801 U1 a wall and ceiling cladding with a heating and/or cooling device in the form of an air conditioning pipe through which an appropriately tempered fluid flows is known. The air conditioning pipe is fixed in a heat-conducting profile, which in turn is fastened with several heat-conducting profiles arranged parallel to one another in a bracket that runs perpendicular to the heat-conducting profiles and is suspended at end pieces between two parallel mounting rails. The support rails are attached to parallel support beams at constant intervals and form a substructure fixed to a wall or ceiling, as is generally known to those skilled in the art as a so-called stud frame from drywall construction. Cladding panels are attached to a plane formed by the support rails and the heat-conducting profiles, in particular in the form of gypsum-cardboard panels.

The DE 201 06 884 U1 describes a ceiling structure with heat-conducting profiles in which a pipe is arranged in a bead and clamped. The heat-conducting profiles are designed in the form of sheet metal strips, which, among other things, are angled Have sections which are provided by forming hanging or holding sections for hanging on a base or a fine grid of a ceiling structure fixed to it. Also EP 2 653 792 B1 discloses the formation of hooks in the area of grooves in a sheet metal strip that are open downwards in an installed position, the grooves in turn serving to clamp a pipeline. Here, only the reversible deformability of a rolled sheet metal profile is provided in the area of the grooves, profile walls protruding from each groove in order to form an extra extended handle on a hook. These hooks are in turn intended for hanging the metal strips as heat-conducting profiles on a ceiling substructure.

DE 20 2018 103 991 U1 discloses a modification of this structure by providing a mounting rail as a system rail with connecting elements integrally integrated thereon, which is designed as stamped and bent parts for snapping in heat-conducting profiles provided with corresponding locking lugs. These mounting rails are suitable for direct mounting on a mounting surface, i.e. a wall or a ceiling. This mounting rail and the heat-conducting profiles are made from roll-formed sheet steel strips. This system has basically proven itself.

The present invention has the object of creating a cladding system with a heating and/or cooling device which has further improved properties.

This object is achieved according to the invention by the features of claim 1 in that a cladding system with a support device and heating and / or cooling device, in which an air conditioning pipe in an approximately omega-shaped receptacle Heat-conducting profile is fixed and the heat-conducting profile made of roll-formed sheet metal can be attached to a wall or a ceiling via the support device, the heat-conducting profile being designed in such a way that the air-conditioning tube is pressed in with reversibly resilient expansion of the approximately omega-shaped receptacle and in the heat-conducting profile with good thermal connection is permanently fixed, and the heat-conducting profile has at least one locking lug in an outer area of the approximately omega-shaped receptacle and a corresponding resilient locking arm is provided on the support device. Using a proven technology, the heat-conducting profile made of roll-formed sheet metal is redesigned according to the invention in such a way that at least one locking lug is now provided in an outer area of the approximately omega-shaped receptacle, instead of at least one known locking arm or hook of comparatively large length. Furthermore, a quick and secure locking mechanism can be produced on a support device in that a support device now has a spring-elastic locking arm corresponding to this locking lug of the heat-conducting profile. Fixing in the form of a latching is superior to simply hanging a heat-conducting profile on a ceiling substructure from a safety perspective. Another significant advantage of a cladding system according to the invention is that the formation of a locking lug on the heat-conducting profile requires significantly less sheet metal and this advantageous saving is essentially retained by the formation of a locking arm on the support device. This material saving significantly reduces the weight compared to known devices and thus opens up significant cost advantages using known manufacturing processes based only on sheet metal processing. A design according to the invention of a heat-conducting profile has a significantly simplified cross-sectional area with sufficient bending rigidity to prevent sagging in one Installation position. In addition, a portion of the surface of the heat-conducting profile is increased, which is effectively used for heat transport in interaction with a room to be air-conditioned.

At the same time, the completely spring-elastic property of roll-formed sheet steel is always sufficient to form the approximately omega-shaped holder for the defined and secure reception of the air conditioning pipe. A known fixation of an air conditioning pipe by simply pushing it into the receiving groove of the heat-conducting profile is therefore possible without causing damage. This means that an air conditioning pipe can be flexibly fixed in the heat-conducting profile itself with a freely selectable length of the air conditioning pipe with a short-term spring-elastic expansion of the approximately omega-shaped receptacle after completion of the other assembly work. An arbitrarily selectable length of an air-conditioning pipe can, for example, be laid in a meandering shape over heat-conducting profile sections that are fixed parallel to one another on a ceiling and cut to length as required to optimize coverage of every conceivable surface shape of a wall or ceiling.

Advantageous further training is the subject of the subclaims. Accordingly, the heat-conducting profile has, in an outer area of the approximately omega-shaped receptacle, two latching lugs arranged in a mirror-symmetrical manner with respect to a central axis of the approximately omega-shaped receptacle, and two latching arms are provided in a mirror-symmetrical manner on the support device. This means that latches are provided on both sides of the approximately omega-shaped receptacle as secure fixations.

In a further development of the invention, these locking arms are designed to partially encompass the approximately omega-shaped receptacle of the heat-conducting profile. This feature makes the approximately omega-shaped mount equally more resilient Arms created to apply symmetrical force to the heat-conducting profile in the area of the holder.

In an advantageous development of the above-mentioned embodiment, the heat-conducting profile continuously has two formed and mirror-symmetrically arranged locking lugs in an outer area of the approximately omega-shaped receptacle, with two mirror-symmetrical locking arms partially encompassing the approximately omega-shaped receptacle of the heat-conducting profile being provided on the support device, which are designed in the form of defined sections on the support device. The support device thus forms a symmetrical load for the heat-conducting profile, which essentially only acts at points over a length of a heat-conducting profile.

In a preferred embodiment of the invention, the carrying device is designed as a clip made of plastic. This means that the heat-conducting profile made of highly thermally conductive aluminum in contact with the plastic of the clip, which significantly inhibits the outflow of heat or cold, is advantageously largely decoupled from the rest of the substructure of the wall or ceiling cladding. A heat flow can therefore essentially only run between the heat-conducting profile and the air conditioning pipe fixed therein. The release or absorption of heat is therefore better concentrated on the heat-conducting profile. Plastic parts are also very advantageous in terms of weight and also manufacturing costs for larger quantities in terms of their comparatively low production costs, even with more complex shapes, and sufficiently high mechanical strength and corrosion resistance compared to stamped and bent parts made of sheet metal.

In a particularly preferred embodiment of the invention, the latching arms of the support device open into a base.

In one embodiment of the invention, this base is formed on the support device in a fully installed state in the area of the approximately omega-shaped receptacle of the heat-conducting profile.

According to an advantageous development, locking arms are then provided on the base of the support device and are designed to lock the support device on a support rail. The carrying device therefore has an advantageous locking dual function.

In one embodiment of the invention, the locking arms of the carrying device also have predetermined breaking points. These predetermined breaking points are designed for the targeted removal of these latching arms from the base, so that a base of the support device can also be fixed directly to a wall or ceiling instead of latching to a support of a ceiling substructure. For this purpose, in one embodiment of the invention, the base also has a recess through which the carrying device can be directly fixed, in particular screwed, via the base.

In a preferred embodiment of the invention, the carrying device is designed to be height-adjustable. In a further development of the invention, this height adjustment is realized via a screw connection on the base, through which, in addition to setting up a predetermined distance, smaller to larger tolerances, for example between a ceiling surface and a heat-conducting profile, can be compensated for easily and without the use of additional tools.

In a further development of the above embodiment of the invention, a base plate is provided on a T-piece of the screw connection, which is designed for direct attachment to a wall. For this purpose, in one embodiment the Invention radially distributed recesses and/or a central recess are provided in the base plate of the T-piece for carrying out screw connections.

Across the various illustrations and exemplary embodiments, the same reference numbers are always used below for the same elements. Without limiting the invention For this application, only one use of a cladding system on a ceiling is described below. An adjustment for use, for example on a wall that is vertical or slanted at an angle, can be implemented without any problems by a specialist.

Figure 5 shows two designs of a known cladding system 1 of a ceiling, not shown, in a side view. The wall and ceiling cladding shown is equipped as a cladding system 1 with a heating and/or cooling device in the form of an air conditioning pipe 2, through which an appropriately tempered fluid flows. Here, two air conditioning pipes 2 are fixed in a heat-conducting profile 3, the heat-conducting profile 3 being a roll-formed galvanized steel sheet having several sections: a first horizontal section 4a, which has a part of an omega-shaped receptacle 5 for a first air conditioning pipe 2 in a locking arm 6 and continues in one piece from there to a second part of the omega-shaped receptacle 5 back into a central horizontal section 4b, to which there is another omega-shaped receptacle 5 for a second air conditioning pipe 2 with a locking arm 6 and a final horizontal section 4c connects. The omega-shaped receptacles 5 are resilient to such an extent that an air conditioning pipe 2 is pressed through their opening and is held permanently and securely over a length of the heat-conducting profile 3. This heat-conducting profile 3 is constructed in mirror image to a central axis M, so the locking arms 6 are each aligned in opposite locking directions.

In Figure 5 Two known types of self-locking suspension of the heat-conducting profiles 3, each equipped with two air conditioning pipes 2, on a support device 7 are shown: In the upper half of Figure 5 has one of several mounting rails 8 running parallel to one another at certain distances approximately T-shaped punched out 9 bent up by approximately 90 °, the punched out 9 also being symmetrical. Free ends 10 of this punched out 9 serve as locking lugs on which the locking arms 6 of the heat-conducting profile 3 engage in a resilient manner. This arrangement essentially corresponds to the teaching of DE 20 2018 103 991 U1 .

In the lower half of Figure 5 On the other hand, instead of a punched out 9 on the mounting rail 8, a U-shaped anchor bracket 11 is arranged on the mounting rail 9 so that it can be moved horizontally in the manner indicated by the double arrow. The anchor angle 11 also has T-shaped legs 12 with free ends 10 as a sheet metal body. As described above, these ends 10 in turn serve as locking lugs for resilient engagement of the locking arms 6 of the heat-conducting profile 3.

In any case, the mounting rail 8 is suspended here from a surface of a ceiling (not shown) by a so-called vernier bracket 13. To form a suspended ceiling, support rails 8 are fixed to the ceiling in this way at constant distances parallel to one another. Such ceiling substructures using standard parts are generally known to those skilled in the drywall construction sector in terms of their dimensions and design and will therefore not be described further here, since exemplary embodiments according to the invention can also be seamlessly integrated into this area.

The sections 4a, 4b, 4c form a flat horizontal surface 4 on the heat-conducting profile 3 with a free outside 14, which creates a distance d from the mounting rail 8. A thin layer of gypsum-cardboard panels 15 is fixed to this free outside 14 as a uniform finish to the cladding system 1. A firm connection of the layer of gypsum cardboard 15 to a wall 16 is formed here by a U-profile 17.

Figure 1 represents a sectional view of a first exemplary embodiment of a novel cladding system 1 analogous to the view of Figure 5 which has further improved properties compared to the prior art described above. The heat-conducting profile 3 is designed as a roll-formed sheet of galvanized steel with an approximately omega-shaped receptacle 5 for an air conditioning pipe 2. In the area of the horizontal surface 4 of the heat-conducting profile 3 are compared to the representation of Figure 5 Elongated holes 20 have been added, which serve as an effective means of positively influencing room acoustics. A further improvement in room acoustics is achieved if in the sectional view of Figure 1 In the manner indicated, recesses aligned with the elongated holes 20 are also provided in the gypsum-cardboard board 15, which, after a finished construction of the cladding system 1, is fixed to the free outside 14 of the horizontal surface 4 of the heat-conducting profile 3, preferably by screw connections, as is already the case in Figure 5 shown and described. The spring elasticity of the heat-conducting profile 3 is basically sufficient for pressing in the air conditioning pipe 2 and subsequently holding it securely and permanently. After mounting the heat-conducting profile 3, for example on the mounting rail 8, the air conditioning pipe 2 can be inserted or pressed in without any problems in a known manner with reversibly elastic expansion of the approximately omega-shaped receptacle 5 of the heat-conducting profile 3 and permanently in the heat-conducting profile 3 with a good thermal connection be fixed. If an increase in the spring elasticity of the receptacle 5 is nevertheless desired, the formation of an additional spring-groove 19 in the area of a central axis M is advisable, as in Figure 1 indicated by dots.

In this exemplary embodiment, the heat-conducting profile 3 has two mirror-symmetrical ones on the approximately omega-shaped receptacle 5 Locking lugs 21 arranged on a central axis M. The locking lugs 21 replace the locking arm 6 of Figure 5 and are designed to engage on locking lugs 22 of a carrying device 7. The thermal conduction profile 3 from Figure 1 has a thermally active surface that is compared to the known design of Figure 5 is significantly enlarged compared to an overall surface.

For each locking lug 21, a corresponding spring-elastic locking arm 22 is provided on the associated support device 7, as in Figure 2 shown. This second exemplary embodiment thus represents a reversal of the prior art Figure 5 Now, instead of locking arms 6, two mirror-symmetrical locking arms 22 are provided on the support device 7 and partially surround the approximately omega-shaped receptacle 5 of the heat-conducting profile 3, at least on the locking lugs 21 and are designed here as two sections, as shown in the perspective view of the cladding system Figure 2 is shown.

These locking arms 22 end in a base 23. Opposite the locking arms 22, locking arms 24 are then provided on this base 23, which are designed to lock the support device 7 on the support rail 8, not shown. The carrying device 7 is thus designed to form a cross connection between a mounting rail 8 and the heat-conducting profile 3. Recesses 25 are also provided in the locking arms 24, through which the locking arms 24 can also be fixed to the mounting rail 8. This mounting rail 8 represents a standard drywall component and is therefore not shown further here.

The carrying device 7 additionally has predetermined breaking points 26, which are designed for the targeted removal of these locking arms 24 from the base 23. This means that the base 23 could also be fixed directly on the mounting rail 7 or a wall or ceiling. For this A central recess 27 is provided in the base 23, through which a screw connection can be defined and carried out safely.

The consequence of the Figures 3a to 3d additionally shows three views of the first exemplary embodiment of a cladding system 1 according to Figure 1 and additionally a modification in the form of a multiple carrying device. In this exemplary embodiment and for subsequent modifications, the carrying device 7 is designed as a clip made of plastic, which gives a shape design additional degrees of freedom compared to stamped and bent parts made of sheet metal. Accordingly, when the entire support device 7 is designed in one piece, the locking arms 22 open into a base 23, which is provided in an installed position in particular in the area of the tongue-and-groove 19. In a modification according to Figure 3d There are now three supporting devices 7 here Figure 3b via a common base 23 and locking arms 24 as a unit 7 'for receiving three heat-conducting profiles 3 and fixing them on a mounting rail 8. Such units with two or four support devices 7 that are integrally connected to one another in the manner described are not shown any further. All the features of a single support device 7 otherwise described above are also carried out here without a detailed description. In a type of multiple use, all forms of use or attachment are possible with more rational attachment.

Figures 4a to 4c are views of a second exemplary embodiment of a cladding system 1 in three representations analogous to the illustrations Figures 3a to 3c . Essentially different from the second exemplary embodiment, the carrying device 7 is designed in two parts and is height-adjustable, which is realized here by a screw connection 28. Through this screw connection 28, the base 23 is rotatably fixed in a height-adjustable manner on a T-piece 29 with a slight incline, as indicated by arrows in the figures. The T-piece 29 in turn is designed for direct attachment to a wall, for example. For this purpose, radially distributed openings 30 are provided on a base plate 31 of the T-piece 29. Both components of the carrying device 7 are here again designed as plastic parts that are manufactured in an injection molding process. From the base 23 to the heat-conducting profile 3, the supporting device 7 is then constructed as already shown and described for the second exemplary embodiment.

Across all exemplary embodiments, it is preferred to make the carrying device 7 as one piece as possible in plastic. This means that in the first exemplary embodiment, the anchor angle 11 can also be manufactured as a U-shaped bracket made of plastic, instead of using the already known component made of sheet metal. The carrying device 7 thus acts across the exemplary embodiments as a thermal decoupling of the heat-conducting profile 3 relative to a mounting rail 8 with a possibly adjoining substructure, as is usually constructed from standardized metal parts adapted to a respective application in a manner known to those skilled in the art.
