COVERING SYSTEM WITH HEATING AND/OR COOLING DEVICE

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

[0002] DE 20 2010 011 801 U1 discloses a wall and ceiling paneling with a heating and/or cooling device in the form of an air-conditioning pipe through which an appropriately temperature-controlled fluid flows. The air-conditioning tube 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 which 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 the person skilled in the art as 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 plasterboard panels.

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

The systems described above have basically proven themselves.

The object of the present invention is to provide a cladding system with further improved properties.

This object is achieved according to the invention by the features of claim 1. Accordingly, the heat-conducting profile is designed as an aluminum extruded profile with an approximately omega-shaped receptacle for the air-conditioning tube, the approximately omega-shaped receptacle having a tongue and groove. A major advantage of a cladding system according to the invention is that a heat-conducting profile made of an aluminum extruded profile can be produced much more easily and cheaply than a roll-formed radiant sheet in terms of manufacturing technology and weight with at least comparable heat conduction. Another advantage of aluminum as a material is its significantly better corrosion resistance to water. At the same time, the elasticity of extruded aluminum in the area of the approximately omega-shaped receptacle through the spring groove is sufficient to form an approximately omega-shaped receptacle for defined and secure accommodation of the air-conditioning tube. A climate tube can thus be flexibly fixed in the heat-conducting profile itself with a freely selectable length of the climate tube with a short-term spring-elastic expansion of the approximately omega-shaped receptacle after completion of the other assembly work. For example, in a meandering form, any length of an air-conditioning pipe that can be selected can be laid over heat-conducting profile sections fixed parallel to one another on a ceiling to cover any conceivable surface shape. Advantageously, the tongue and groove lies in an axis of symmetry of the approximately omega-shaped receptacle. This feature creates equally strong springy arms at the roughly omega-shaped receptacle.

[0007] Advantageous developments are the subject matter of the dependent claims. Accordingly, in one embodiment of the invention, the heat-conducting profile has an approximately W-shaped cross section. This special cross-sectional shape is realized in that two latching arms are provided in an outer area adjacent to the approximately omega-shaped receptacle, which are designed for spring-elastic latching engagement with latching lugs of a carrying device, in particular a carrying rail according to the teaching of DE 20 2018 103 991 U1.

According to a preferred embodiment of the invention, the heat-conducting profile has

an outer area of the approximately omega-shaped recording at least one locking lug. A corresponding spring-elastic latching arm is provided on the carrying device. This design of a heat-conducting profile has a significantly simplified cross-sectional area. In addition, a proportion of a surface of the heat-conducting profile is increased, which is used effectively for heat transport in conjunction with a room to be air-conditioned.

In an advantageous development of the above-mentioned embodiment, the heat-conducting profile has two mirror-symmetrically arranged locking lugs in an outer area of the approximately omega-shaped receptacle, and two locking arms are provided on the support device that are mirror-symmetrical and partially encompass the approximately omega-shaped receptacle of the heat-conducting profile. The spring-elastic locking arms are preferably designed in the form of defined sections on the support device. The support device thus forms a symmetrical load for the heat-conducting profile.

In a preferred embodiment of the invention, the carrying device is designed as a clip made of plastic. In this way, the heat-conducting profile made of aluminum with good thermal conductivity is advantageously largely decoupled from the rest of the substructure of the wall or ceiling paneling in contact with the plastic of the clip, which significantly inhibits the outflow of heat or cold. A flow of heat can thus essentially only run between the heat-conducting profile and the air-conditioning tube fixed therein. A release or absorption of heat is thus better concentrated on the heat-conducting profile. Plastic parts are also very advantageous in terms of their comparatively low production costs, even with a more complex shape, with 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 locking arms of the support device open into a base. This base is formed on the support device in a fully installed state, in particular in the area of the tongue and groove of the heat-conducting profile.

[0012] According to an advantageous further development, latching arms are provided on the base of the support device, which are designed to latch the support device to a support rail and preferably 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. For this purpose, in one embodiment of the invention, the base also has a recess, through which the carrying device can be fixed directly via the base, in particular screwed.

In a preferred embodiment of the invention, the support device is adjustable in height. This height adjustment is implemented in particular via a screw connection on the base, which, in addition to setting up a predetermined distance, can also be used to easily compensate for smaller and larger tolerances, for example between a ceiling surface and a heat-conducting profile.

In a further development of the above embodiment of the invention, a base is formed on a T-piece of the screw connection for direct attachment to a wall, in particular through recesses in the base of the T-piece for the implementation of screw connections.

Further features and advantages of embodiments according to the invention are explained in more detail below with reference to exemplary embodiments based on the drawing. It shows in a schematic representation:

[0022] FIG. 7: a side view of two designs of a known cladding system.

The same reference symbols are always used below for the same elements across the various figures and exemplary embodiments. Without restricting the invention to this application, only one use of a cladding system with a heating and/or cooling device on a ceiling is described below. An adjustment to an application, e.g. on a wall, can be implemented by a specialist without any problems.

Figure 7 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 temperature-controlled fluid flows. Two air-conditioning pipes 2 are fixed here in a heat-conducting profile 3, with the heat-conducting profile 3 having several sections as a roll-formed, galvanized sheet steel: a first horizontal section 4a, which has part of an omega-shaped receptacle 5 for a first air-conditioning pipe 2 in a latching arm 6 and continues in one piece from there to a second part of the omega-shaped receptacle 5 back into a middle horizontal section 4b, to which another omega-shaped receptacle 5 for a second air-conditioning tube 2 with a latching arm 6 and one final horizontal section 4c connects. The omega-shaped receptacles 5 are spring-elastic to the extent that an air-conditioning tube 2 is held pressed in through their opening permanently and securely over a length of the heat-conducting profile 3 . This heat-conducting profile 3 is constructed as a mirror image of a central axis M, so that the latching arms 6 are aligned so that they latch in opposite directions.

7 shows two known types of self-locking suspension of the heat-conducting profiles 3, each equipped with two air-conditioning tubes 2, on a support device 7: In the upper half of FIG approximately T-shaped and about 90 ° bent punch 9, wherein the punch 9 is also symmetrical. Free ends 10 of this punched portion 9 serve as latching lugs on which the latching 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 7, however, a U-shaped anchor bracket 11 is arranged horizontally displaceable on the support rail 9 in the manner indicated by the double arrow instead of a punched 9 on the support rail 8. The anchor bracket 11 has, as a sheet metal body, likewise T-shaped legs 12 with free ends 10 . As described above, these ends 10 in turn serve as latching lugs for spring-elastic engagement of the latching arms 6 of the heat-conducting profile 3.

In any case, the support rail 8 is suspended here from a surface of a ceiling, not shown, by a so-called vernier bracket 13 . In order to form a suspended ceiling, support rails 8 are fixed parallel to one another in this way on the ceiling at constant intervals. Such substructures are basically known to the person skilled in the art of dry construction in terms of their dimensioning and design and are therefore not described further at this point, since exemplary embodiments according to the invention are also seamlessly integrated into this area.

The sections 4a, 4b, 4c form a flat horizontal surface on the heat-conducting profile 3

4 with a free outer side 14, which creates a distance d to the mounting rail 8. A thin layer of plasterboard panels 15 is fixed to this free outer side 14 as a uniform conclusion of the cladding system 1 . A solid connection of the layer of plasterboard 15 to a wall 16 is formed here by a U-profile 17.

Figure 1 shows a sectional view of a first embodiment of a new type of cladding system 1 analogous to the view of Figure 7, which has compared to the prior art described above further improved properties. The heat-conducting profile 3 is designed as an aluminum extruded profile with an approximately omega-shaped receptacle 5 for an air-conditioning tube 2 . In addition, the heat-conducting profile 3 has an approximately W-shaped cross-section because two latching arms 6 are provided adjacent to the approximately omega-shaped receptacle 5 in an outer area, which are designed to engage with latching lugs 10 of a carrying device 7 . The support device 7 can be designed in an adapted manner in the form of a punched-out portion 9 of a support rail 8 bent from sheet metal, as already described above for FIG. Here, however, the support device 7 is designed as a leg 12 of an anchor bracket 11, as also shown in FIG. In order to reduce the overall height, a recess 18 is provided in the leg 12 which is adapted to the approximately omega-shaped receptacle 5 . In a way that is only indicated in FIG. 1, in an alternative embodiment only one edge running in a straight line is provided at this point, against which the heat-conducting profile 3 rests in an installed position. Furthermore, the legs 12 of the anchor bracket 11 have external flanks which serve as guides for the latching arms 6 of the heat-conducting profile 3 until they latch securely.

The thermally conductive profile 3 of FIG. 1 has a thermally active surface that is significantly larger than the known design of FIG. 7 compared to a total surface. In addition, the production of an extruded aluminum profile, even with the very complex cross-section shown here, is a clearly simpler and more cost-effective process compared to roll-folded or roll-formed profiles made of sheet steel. Even a superficially galvanized steel sheet is significantly more susceptible to corrosion, especially to constant condensation from the air or rust film, than an aluminum profile could ever be. After all, aluminum is significantly lighter than a profile bent from sheet steel with comparable mechanical strength. In addition, the approximately omega-shaped receptacle 5 of the heat-conducting profile 3 has a tongue and groove 19 . The spring-groove 19 is located in a central axis M of the omega-shaped receptacle 5 as the axis of symmetry in order to create equally strong springy arms. In terms of spring elasticity, this extruded aluminum profile thus corresponds to a comparable roll-formed profile made from sheet steel. After the heat-conducting profile 3 has been installed, e.g.

Figure 2 is a perspective view of the first exemplary embodiment of the heat-conducting profile 3, in which elongated holes 20 have been added here in the area of the horizontal surface 4 of the heat-conducting profile 3, which serve as an effective means of positively influencing room acoustics, as already shown in Figure 1 indicated. A further improvement in the room acoustics is achieved if in the manner indicated in the sectional view of Figure 1 also with the elongated holes 20 aligned recesses are provided in the plasterboard 15 after a finished construction of the cladding system 1 on the free Outside 14 of the horizontal surface 4 of the heat-conducting profile 3 is preferably fixed by screwing, as already shown and described in Figure 7.

Figure 3 shows a sectional view of a part of another embodiment of a heat conducting profile 3 for a cladding system 1, in which a plasterboard panel 15 is fixed in a manner not shown on the free outer side 14 of the horizontal surface 4. This heat-conducting profile 3 is characterized in that it has at least one latching lug 21 in an outer area of the still approximately omega-shaped receptacle 5, here two latching lugs 21 arranged mirror-symmetrically in relation to the spring-groove 19.

A corresponding spring-elastic locking arm 22 is provided for each locking lug 21 on the associated support device 7, as shown in FIG. This second exemplary embodiment thus represents a quasi-reversal of the first-described exemplary embodiment of FIG 22 is provided, as is also shown in FIG. 4 in the perspective view of the cladding system according to the second exemplary embodiment. These locking arms 22 end in a base 23 .

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

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

The sequence of Figures 5a to 5d shows three additional views of the second embodiment of a cladding system 1 according to Figure 4 with a modification in the form of a multiple support device. From this second exemplary embodiment and for subsequent modifications, the carrying device 7 is designed as a clip made of plastic, as a result of which a shape design is given additional degrees of freedom compared to stamped and bent parts made of sheet metal. Accordingly, when the entire support device 7 is formed in one piece, the latching arms 22 end in a base 23 which is provided in an installation position, in particular in the area of the spring-groove 19 . In a modification according to FIG. 5d, three supporting devices 7 according to FIG. Units of this type with two or four support devices 7 connected to one another in one piece in the manner described are also not shown in any more detail. All the features of an individual support device 7 otherwise described above are also set 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 6a to 6c are views of a third embodiment of a cladding system 1 in three representations analogous to the illustrations of Figures 5a to 5c. The essential difference to the second exemplary embodiment is that the support device 7 is designed in two parts and is adjustable in height, which is realized here by a screw connection 28 . This screw connection 28 fixes the base 23 in a height-adjustable, rotatable 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. Openings 30 are provided on a base of the T-piece 29 for this purpose. Both components of the support device 7 are in turn designed here as plastic parts that are produced in an injection molding process. From the base 23 to the heat-conducting profile 3, the support device 7 is then constructed as already shown and described for the second exemplary embodiment.

Across all exemplary embodiments, preference is given to carrying out the carrying device 7 in one piece as far as possible from plastic. Thus, in the first exemplary embodiment, the anchor angle 11 can also be produced as a U-shaped bracket made of plastic, instead of using the already known component made of sheet metal. The support device 7 thus acts as a thermal decoupling of the heat-conducting profile 3 in relation to a support rail 8 with a possible subsequent substructure, as is constructed in a manner known to those skilled in the art, usually adapted from standardized metal parts to a particular application.
