In order to create a retaining rail of the type described above, it is proposed that two adjacent receptacles (3) are arranged offset from one another in a base position with respect to an adjustment direction (19) pointing from the drywall panel (8) and running transversely to the longitudinal direction (2) of the rail, and that the receptacles (3) are coupled to one another via a coupling web (13, 14) in such a way that they can be displaced relative to one another from the base position into an adjustment position with the specification of a common support plane extending parallel to the drywall panel (8) with respect to the adjustment direction (19).

Description

[0001] The invention relates to a retaining rail for fastening to drywall profiles, wherein the retaining rail comprises receptacles for heat conducting bodies which are adjacent in the longitudinal direction of the rail and are open towards an outer side of the rail and which can be placed with a contact surface against a drywall panel.

[0002] For temperature control of room walls, it is known to provide support rails that are attached to drywall profiles behind any drywall panels. The support rail comprises receptacles for heat conducting elements, which in the simplest case are formed by a heat exchanger itself, for example, a pipe coil through which a temperature control medium flows. However, it is also known (EP3722681A1), for example, for the heat conducting elements to each have a heat conducting profile, which comprises a substantially plate-shaped base body and a clamping body projecting therefrom for corresponding pipe sections of a pipe coil.

[0003] However, the retaining rails, which are typically made of lightweight materials for manufacturing and cost reasons and are preferably made of plastic, are prone to warping, so that the heat-conducting elements fixed in the corresponding recesses do not fully adhere to the drywall or are spaced at different distances from it. This leads to uneven heat transfer through the heat-conducting elements and consequently to reduced efficiency.

[0004] The invention is therefore based on the object of providing a retaining rail of the type described above which is both easy to manufacture and assemble and which, when installed, enables reliable and uniform heat transfer to a drywall panel by means of heat conducting elements.

[0005] The invention achieves this objective by providing two adjacent receptacles in a base position offset relative to one another in a direction of travel extending from the drywall panel and transverse to the longitudinal direction of the rail. The receptacles are coupled to one another via a coupling web in such a way that they can be displaced relative to one another from the base position into a travel position, while maintaining a common support plane extending parallel to the drywall panel. Due to these features, the coupling web forms a type of rocker that connects the adjacent receptacles, which are offset relative to one another in the travel direction, and thus, by placing a drywall panel against the retaining rail, causes the two receptacles to be displaced relative to one another in the travel direction.The provision of a common support plane extending parallel to the drywall panel therefore means that, in the installed position, the receptacles are aligned relative to one another such that the heat-conducting elements accommodated therein rest snugly and evenly against the drywall panel with their corresponding contact surfaces. The measures according to the invention thus prevent individual heat-conducting elements from not adhering to the drywall panel when installed, or from forming an undesirable air gap between individual heat-conducting elements and the drywall panel, which reduces efficiency. The receptacles are preferably open toward the outer side of the rail that faces the drywall panel when installed.

[0006] Particularly favorable installation conditions arise when the mounts can be moved from the base position to the set position under preload. In addition to the haptic feedback provided by the preload, which facilitates proper installation, the preload ensures that all heat-conducting elements rest snugly against the drywall panel in the set position.

[0007] In order to enable reliable displacement of the receptacles between the base and the adjustment position in a structurally simple manner and to increase the stability of the retaining rail, it is proposed that the coupling web be connected via a support to a longitudinal web running opposite the receptacles in the longitudinal direction of the rail, wherein the coupling web is designed to be elastic. The support acts as a bearing and thus as a pivot point for the elastic coupling web. The rail profile resulting from the design due to the support and the longitudinal web also achieves stiffening, thus giving the retaining rail appropriate stability. In principle, it can be provided that not only the coupling web but also the longitudinal web running in the longitudinal direction of the rail is designed to be elastic. The entire retaining rail is preferably made in one piece from plastic.

[0008] Typically, the receptacles for the heat conducting elements define an imaginary surface that essentially corresponds to the cross-sectional shape of a corresponding heat conducting element or the heat conducting element section accommodated in the receptacle. For example, in the case of circular tubular heat conducting elements, the receptacles of the retaining rail can be designed such that they are open on one side and essentially delimit a circular area in cross-section. In order to ensure advantageous manufacturing and assembly conditions, it is therefore recommended that the coupled receptacles be offset from one another with respect to their respective center of gravity in the base position, and that the connecting line of the center of gravity runs parallel to the support plane in the set position.

[0009] In order to attach the heat conducting elements to the support rail in a particularly space-efficient manner with a robust design, without compromising the rocker effect that is advantageous for assembly, it is recommended that a central mount be provided that is centrally located with respect to the longitudinal direction of the rail and that this is coupled to adjacent secondary mounts on both sides via a coupling web, and that in the base position the central mount protrudes relative to the secondary mounts in the opposite direction to the adjustment direction. This measure creates the prerequisite for additional secondary mounts to be connected to the secondary mounts adjacent to the central mount on both sides, either in or against the longitudinal direction of the rail. These additional secondary mounts can preferably be connected to one another without corresponding coupling webs, thus achieving a correspondingly compact design.If, during installation, the heat conducting element held in the central holder is positioned in the direction of adjustment against the drywall panel, the coupling webs arranged on both sides of the central holder cause a corresponding displacement of the secondary holders towards the drywall panel, so that all heat conducting elements held in the holders lie snugly against the drywall panel.

[0010] The invention also relates to an air conditioning device with a support rail according to the invention. The support rail is attached to respective drywall profiles at both ends. Furthermore, heat-conducting elements are inserted into the support rail's receptacles, the contact surfaces of which can be placed against a drywall panel in the direction of travel.

[0011] Favorable design conditions arise when the heat-conducting bodies have a passage extending transversely to the longitudinal direction of the rail for accommodating a heat exchanger, preferably a pipe coil, through which a temperature control fluid flows, and whose respective contact surfaces, which can be placed against the drywall panel, form flat support surfaces. For example, the heat-conducting bodies can each have a preferably metallic heat-conducting profile comprising a substantially plate-shaped base body and a guide body, which is thermally connected to the base body and forms the passage for a corresponding heat exchanger section, in particular a pipe section of a pipe coil. The plate-shaped base body and the guide body are in particular formed integrally as such a heat-conducting profile, wherein the plate-shaped base body forms the contact surface for a drywall panel.The passage is preferably designed to be open on the contact surface side, particularly for clamping heat exchanger sections, e.g., pipe sections. When installed, this contact surface side of the heat profile thus faces the drywall panel.

[0012] The drawing shows an example of the subject matter of the invention. Fig. 1 a schematic front view of a holding rail according to the invention with receptacles in the basic position and Fig. 2 one of the Fig. 1 corresponding representation on a smaller scale, with the mounts in the adjusted position and consequently positioned against a drywall panel, with the heat conducting body resting firmly on it.

[0013] A holding rail 1 according to the invention has receptacles 3 for heat-conducting bodies 4, which are adjacent in the longitudinal direction 2 and open towards an outer side of the rail. In the exemplary embodiment shown, the heat-conducting bodies 4 are each designed as a metallic heat-conducting profile, which comprises a substantially plate-shaped base body 5 and a guide body 6. The plate-shaped base body 5 forms a contact surface 7 against which a drywall panel 8 can be placed. The guide body 6 comprises a passage 9 for a pipe section, indicated by a dash-dotted line, of a pipe coil which carries a temperature control medium. For this purpose, the passage 9 is open on the contact surface side for clamping the pipe section.

[0014] According to the present embodiment, the receptacles 3 of the retaining rail 1 are formed by a central receptacle 10 arranged centrally with respect to the longitudinal axis of the rail 2, as well as secondary receptacles 11, 12. The secondary receptacles 11, 12 are arranged adjacent to the central receptacle 10 on both sides and are coupled to it via a coupling web 13, 14, respectively.

[0015] The latter are each connected via a support 15, 16 to a longitudinal web 17 opposite the receptacles 3 and extending in the longitudinal direction 2 of the rail. In order to improve the structural integrity of the retaining rail 1, it can in principle have a further second longitudinal web 18 running parallel to the first longitudinal web 17 and arranged on the side of the retaining rail 1 opposite the receptacles 3.

[0016] As this is Fig. 1 As can be seen, the central receptacle 10 protrudes relative to the secondary receptacles 11, 12 in the opposite direction of incidence 19. Accordingly, in the present case, in the base position, the secondary receptacles 11, 12 are arranged offset relative to the central receptacle 10 with respect to their respective center of gravity.

[0017] If, for example, a drywall panel 8 is placed in the adjustment direction 19 against the holding rail 1 and thus against the heat conducting body 4, this results in a displacement of the receptacles 3 under prestress from the position shown in the drawing due to the elastically designed coupling webs 13, 14 acting in the sense of a rocker. Fig. 1 shown base position into the Fig. 2 The central mount 10 is displaced in the direction of adjustment 19, while the secondary mounts 11, 12 are displaced against the direction of adjustment 19, as shown by the arrows in Fig. 2is indicated. In the installed position, the receptacles 3 thus define a common support plane extending parallel to the drywall panel 8, with the connecting line of the centroids of the receptacles 3 running parallel to the support plane. Consequently, the contact surfaces 7 of the heat-conducting elements 4 form flat support surfaces, so that all heat-conducting elements 4 rest snugly against the drywall panel 8.

[0018] The support rail 1 can generally be attached to drywall profiles 21 via snap-in connectors 20, as shown in the drawing.
