Description

[0001] The invention relates to a fastening device for fastening a sound absorber to a mounting rail.

[0002] Appropriate fastening devices are generally known. Screw connections are usually used to attach the sound absorber to the mounting rail. Due to the tools required, assembly and / or disassembly is comparatively complex and time-consuming.

[0003] It is therefore an object of the invention to provide a fastening device and a system with a fastening device which ensures quick and simple, preferably tool-free, fastening of a sound absorber to a mounting rail.

[0004] This problem is solved by the subject matter of the independent claims.

[0005] According to the invention, the fastening device is designed and / or can be used for fastening a sound absorber to a mounting rail.

[0006] When installed, the sound absorber is preferably oriented perpendicular to the mounting rail. Alternatively, an angled mounting, for example, in a corner area, is also possible. A certain amount of play is required for this.

[0007] The mounting rail can be attached to a ceiling, for example by screwing.

[0008] The sound absorber can be, for example, a slat and / or baffle, e.g. a metal baffle.

[0009] The fastening device has an insertion section for insertion into a guide of the sound absorber.

[0010] The guide can preferably have undercuts. For example, the guide can be designed as a slotted guide. The guide preferably has two guide rails oriented parallel to each other. The guide rails can, for example, have a U-shaped cross-section.

[0011] The fastening device can be inserted and / or screwed into the guide via the insertion section. The fastening device can thus be installed and / or removed from the sound absorber quickly and easily, preferably without the need for tools.

[0012] The fastening device has a clamping section for clamping to the mounting rail.

[0013] The clamping section allows the fastening device to be clamped to the mounting rail. This allows for quick and easy installation and / or removal of the fastening device from the mounting rail, preferably without the need for tools.

[0014] Due to the clamping section, the fastening device can also be called a clip connector.

[0015] Finally, the fastening device has an intermediate section extending between the insertion section and the clamping section. The intermediate section serves as a connecting link between the insertion section and the clamping section. Preferably, the height of the intermediate section can correspond to the height of the mounting rail.

[0016] Preferably, the insertion section, the intermediate section and / or the clamping section are formed in one piece.

[0017] For example, two fastening devices, preferably of identical design, can be provided, arranged on opposite sides of the mounting rail. The mounting rail is clamped on two sides.

[0018] Further developments of the invention can also be found in the dependent claims, the description and the accompanying drawings.

[0019] According to one embodiment, the fastening device comprises or consists of a metal material and / or a plastic material.

[0020] The metal material can be, for example, steel, e.g. spring steel, and / or aluminum.

[0021] The fastening device can be plate-shaped in its original form. The desired structures can then be cut, milled, machined, lasered, and / or beveled, for example. The fastening device is preferably a beveled sheet metal part.

[0022] Preferably, the fastening device has a uniform thickness.

[0023] According to a further embodiment, the insertion section has two lateral projections.

[0024] Preferably, the projections can be of identical construction.

[0025] For example, at least one projection, preferably both projections, may extend in the same direction as the clamping portion.

[0026] Alternatively, at least one projection, preferably both projections, may extend in the opposite direction to the clamping portion.

[0027] For example, the projections may extend in the same direction. Alternatively, the projections may extend in different directions. For example, one projection may extend in the same direction as the clamping portion, while the other projection may extend in the opposite direction to the clamping portion.

[0028] The projections can be beveled. For example, they can be oriented at right angles to the intermediate section.

[0029] Alternatively, at least one projection, preferably both projections, may be straight.

[0030] According to a further embodiment, the insertion section is wider than the intermediate section.

[0031] In this way, the insertion section can form a sliding block for the guide of the sound absorber.

[0032] The fastening device is held securely in the guide by its wide shape and cannot therefore accidentally become detached from the sound absorber, for example by unscrewing it.

[0033] According to a further embodiment, the intermediate section widens from the insertion section to the clamping section.

[0034] The intermediate section can widen evenly or in stages.

[0035] For example, the intermediate section can be V-shaped.

[0036] The fastening device is held securely in the guide, not least by the widening, and can therefore not accidentally detach from the sound absorber, for example by unscrewing it.

[0037] According to a further embodiment, the intermediate section has a hole, preferably an elongated hole.

[0038] The fastening device can optionally be screwed to the mounting rail through the hole.

[0039] This can be useful, for example, when heavy objects, such as lights integrated into the sound absorbers, are attached.

[0040] Furthermore, screwing can be useful when used in earthquake zones.

[0041] According to a further embodiment, the clamping section has a bevel and / or a bend.

[0042] For example, the clamping section can extend in the direction of the mounting rail when mounted.

[0043] The bevel or bend can, for example, form a locking lug, a clamp and / or a clip.

[0044] If the clamping section is pressed over a securing edge of the mounting rail, it can lock into place.

[0045] The fastening device cannot accidentally come loose in this locked position.

[0046] The invention also relates to a system comprising at least one fastening device according to the invention, a mounting rail and a sound absorber.

[0047] Preferably, the mounting rail has an edge region with a securing edge to which the clamping section can be clamped.

[0048] Preferably, two fastening devices are provided. This allows the sound absorber to be attached to the mounting rail on two sides, preventing twisting.

[0049] Protection is claimed for both the assembled and unassembled state of the system.

[0050] According to one embodiment, the sound absorber has a guide for the insertion section of the fastening device. For example, the guide can be formed as a beveled portion integral with the rest of the sound absorber.

[0051] The sound absorber can be attached or is attached to the mounting rail using the fastening device.

[0052] The insertion section can be pushed and / or screwed into the guide.

[0053] Finally, the invention relates to the use of a fastening device according to the invention for fastening a sound absorber to a mounting rail.

[0054] The fastening device allows the sound absorber to be mounted or dismounted on the mounting rail quickly and easily, for example without tools.

[0055] All aspects, embodiments, and features of the invention described here can be combined with each other, preferably independently of the specific embodiment in which they are mentioned. Preferably, all subject matter of the dependent claims can be combined with each other and with each subject matter of the independent claims.

[0056] In general, it should be noted that terms such as "a" or "an" do not necessarily mean "exactly one" or "exactly one," although this is also possible. The terms "a" or "an" can therefore be understood as "at least or exactly one" or "at least or exactly one." The use of the singular preferably includes the presence of the components in the plural, and vice versa.

[0057] It is noted that "vorzugsweise" and "vorzugt" can be translated as "preferably" in English. A feature introduced by "vorzugsweise" or "vorzugt" is purely optional, can be omitted, and does not constitute a limitation, for example, of the claims.

Fig. 1 a perspective view of an embodiment of a fastening device according to the invention, Fig. 2 a rear perspective view of the fastening device according to Fig. 1, Fig. 3 a side view of the fastening device according to Fig. 1, Fig. 4 a perspective view of an embodiment of a system according to the invention in the unassembled state, Fig. 5 a perspective view of the system according to Fig. 4 in the assembled state, and Fig. 6 to 16 perspective views of various embodiments of a fastening device according to the invention.

[0059] First, it should be noted that the illustrated embodiments are purely exemplary in nature. Individual features can be implemented not only in the combination shown, but also individually or in other technically feasible combinations. For example, the features of one embodiment can be combined arbitrarily with features of another embodiment. The number, orientation, shape, and / or position of the projections and / or overhangs is fundamentally arbitrary.

[0060] If a figure contains a reference symbol that is not explained in the immediately corresponding description text, reference is made to the corresponding preceding or following explanations in the figure description. Thus, the same reference symbols are used for identical or comparable components in the figures and these are not explained again.

[0061] Fig. 1, Fig. 2 and Fig. 3 show a fastening device with an insertion section 10, a clamping section 12 and an intermediate section 14 extending between the insertion section 10 and the clamping section 12.

[0071] As in Fig. 7, the hole 28 can be designed, for example, as an elongated hole.

[0072] Instead of one bevel 18, the clamping section 12 can have two bevels 18. These can, for example, be beveled laterally.

[0073] The orientation of the projections 16 is fundamentally arbitrary. They can extend in the same direction as the clamping section 12.

[0074] Alternatively, they can, as in Fig. 8, extend in the opposite direction as the clamping section 12.

[0075] It is also conceivable that, as in Fig. 9, a projection 16 extends in the direction of the clamping section 12 and a projection 16 extends in the opposite direction to the clamping section 12.

[0076] In addition to the projections 16, a notch 30 can optionally be provided. The notches 30 enable a secure hold in the guide 24.

[0077] The notches 30 are purely optional and can, as in Fig. 10 are omitted.

[0078] According to the embodiment shown in Fig. As shown in Figure 11, the clamping portion 12 may have two bevels 18. These may, for example, extend from an upper region.

[0079] As in Fig. 12, the projections 16 can be straight.

[0080] The notches 30 can, as in Fig. 13 are omitted.

[0081] As in Fig. 14, the clamping portion 12 may have a clamping tab 32.

[0082] According to Fig. 15, the projection 18 of the clamping section 12 can be formed as an at least partially round bend 33.
