FASTENING DEVICE

Description

1. Field of the invention

[0001] The present invention relates to a fastening device for fastening a luminaire such as a pendant luminaire to a suspension structure, a luminaire housing comprising such a fastening device, a luminaire comprising such a luminaire housing and a luminaire system comprising such a luminaire. 2. Background

[0002] Fastening devices of the type mentioned at the outset are generally known from the prior art. In particular, luminaires are known which have a fastening device formed with the luminaire body or luminaire housing, which fastens the luminaire to a suspension structure, such as a cable suspension. The suspension structure usually has a suspension element, in particular a cable, and a suspension body, for example in the form of a nipple or a ball, connected to the distal end of the suspension element. The suspension structure can be fixedly mounted to the fastening device, for example with a screw. Alternatively, the suspension structure can also be mounted on the fastening device via a corresponding receptacle by inserting the suspension structure into the fastening device and moving it to a supporting position in which the suspension structure supports the fastening device in a suspended manner.in which the suspension body is blocked in the direction of the load-bearing force. This is achieved, for example, in the simplest form by means of a horizontal slot into which the suspension structure or cable suspension is inserted laterally, so that the suspension structure is suspended accordingly, particularly via the suspension body.

[0003] Another embodiment known from the prior art has a type of keyhole opening, which has an opening with a larger diameter and a further opening with a smaller diameter connected to this directly or via a longitudinal slot. The larger opening has a diameter that is larger than the suspension body. The further or smaller opening, on the other hand, has a diameter that is correspondingly smaller than the suspension body. The longitudinal slot, if present, is preferably narrower than the two openings, but wide enough that, for example, the cable of the cable suspension fits through it. The suspension structure is then inserted into the larger opening with the suspension body first and moved towards the smaller opening, where the suspension structure rests against the suspension body and is thus held.

[0004] To prevent the suspension structure from slipping out or moving, particularly toward the large opening, it is known from the prior art to provide a separately provided locking element, for example in the form of a fastener, between the large and small openings. A screw can be screwed in between the two openings, blocking the connection between these openings, so that the suspension structure is securely held in the area of ​​the small opening and thus cannot slip out of it.

[0005] DE 20 2014 104901 U1 discloses a luminaire housing according to the preamble of claim 1.

[0006] The securing of the suspension structure or the suspension body known from the state of the art is safe, but requires a high level of assembly effort, since in addition to threading the suspension structure, another component is required to block the inserted suspension structure.

[0007] It is therefore an object of the present invention to provide a fastening device of the type mentioned at the outset which enables faster and long-term secure fastening.

[0008] These and other objects, which will be mentioned upon reading the following description or which may be recognized by a person skilled in the art, are achieved by the subject matter of the independent claims. Advantageous further developments are the subject matter of the dependent claims. 3. Detailed description of the invention

[0009] According to a first aspect, the invention relates to a luminaire housing comprising a fastening device for fastening a luminaire, such as a pendant luminaire (or another element), to a suspension structure, with at least one fastening structure, wherein the at least one fastening structure comprises: an opening and a slot connected to the opening, which are designed such that a suspension structure inserted into the fastening device via the opening can be moved via the slot into a supporting position in which the suspension structure supports the fastening device in a suspended manner. The slot has a serrated section for preventing movement of the suspension structure from the supporting position, and the slot is designed such that the suspension structure can be (automatically) driven into the supporting position by the weight of the fastening device.

[0010] According to the invention, "preventing a movement of the suspension structure from the support position" is understood to mean that a manual movement of the suspension structure from the support position (for example by a fitter) is still possible, but an (unintentional) movement of the suspension structure from the support position, in particular due to external forces or impacts acting on the fastening device, is prevented.

[0011] In other words, only the formation of the slot ensures that the suspension structure is secured in the supporting position.

[0012] Separately provided fastening means for securing the suspension structure can thus be eliminated, reducing the number of required components and the assembly effort. Particularly good securing of the suspension structure in the supporting position is achieved when the slot is designed according to the two alternatives. However, for simple securing, the slot can also be provided with only the jagged or deliberately non-rectilinear section, or the slot can be designed such that the suspension structure can be driven into the supporting position by the weight of the fastening device.

[0013] The serrated section has a first and a second sub-section forming the serrated section, wherein the first and the second sub-sections extend in such a way that, when the suspension structure supports the fastening device in the supporting position, a movement of the suspension structure from the first sub-section into the second sub-section and thus out of the supporting position is prevented. In other words, the angle between the first sub-section and the second sub-section ensures that the suspension structure cannot be inadvertently moved out of the supporting position. In particular, with an acute angle, an inadvertent movement of the suspension structure out of the supporting position can be particularly effectively prevented. According to the invention, the angle lies in a range from 20° to 70°, preferably in a range from 30° to 50°, for example substantially 37°.Preferably, the first section is longer than the second section. Consequently, the first section can advantageously absorb external forces or impacts acting on the fastening structure, thus preventing the suspension structure from skidding.

[0014] The slot has at least one further serrated section, wherein the further serrated section is connected (directly) to the opening and (directly) to the serrated section, such that the suspension structure inserted into the fastening device via the opening can be moved into the supporting position via the further serrated section and the serrated section, and the serrated sections can prevent movement of the suspension structure from the supporting position. In this way, the suspension structure can be held even more securely in the supporting position, since the further serrated section, together with the serrated section, provides a type of labyrinth, lightning, or zigzag guide, which even better prevents unintentional movement of the suspension structure from the supporting position.

[0015] The further serrated section can have a (further) first and (further) second subsection forming the (further) serrated section, wherein the (further) first subsection is (directly) connected to the opening and the (further) second subsection is (directly) connected to the serrated section. Preferably, the (further) second subsection of the further serrated section is the second subsection of the serrated section. Thus, the serrated sections of the slot can be easily provided.

[0016] The (further) first and the (further) second sub-sections can extend in such a way that, when the suspension structure supports fastening devices in the carrying position, movement of the suspension structure from the (further) second sub-section into the (further) first sub-section and thus out of the carrying position can be prevented. In other words, the angle between the (further) first sub-section and the (further) second sub-section in particular causes the suspension structure to be moved into the (further) first sub-section and thus out of the carrying position. This angle is preferably acute and particularly preferably lies in a range of 70° to 90°. For example, the angle is substantially 80°.

[0017] The slot preferably extends such that a contact area, with which the suspension structure is in contact in the support position to support the fastening device, is arranged higher than the opening (on the side of the contact area) when the suspension structure supports the fastening device in the support position. The weight of the fastening device thus causes the suspension structure—due to the movement of the fastening device by its weight in the direction of the weight force—to travel the height difference between the opening and the contact area relative to the fastening device in order to reach the support position. The weight of the fastening device thus holds the suspension structure in the support position.The same applies to the manual movement of the suspension structure from the carrying position, in which the fastening device only has to be moved against the weight force by at least the aforementioned height difference.

[0018] The slot runs obliquely to the horizontal when the suspension structure supports the fastening device in the carrying position, so that the suspension structure can be driven into the carrying position by the weight of the fastening device. Thus, securing the suspension structure in the carrying position by the weight of the fastening device can be provided particularly easily. For particularly good securing of the suspension structure in the carrying position, in a particularly preferred embodiment the slot runs at an angle of 5° to 15°, particularly preferably at an angle of 10°, to the horizontal when the suspension structure supports the fastening device in the carrying position.

[0019] The slot is formed in an inclined (sloped) surface of the fastening structure so as to extend obliquely to the horizontal when the suspension structure supports the fastening device in the supporting position. Since an inclined surface is easy to provide, securing the suspension structure in the supporting position by the weight of the fastening device can be particularly easily achieved.

[0020] The at least one fastening structure can have a further opening that is (directly) connected to the slot, in particular to the first subsection of the serrated section, and is designed to hold the suspension structure in the supporting position. The geometry of the further opening thus ensures, in particular, that the suspension structure is held or (partially) received in the supporting position in a defined manner, namely in the region of the opening. It is preferred if the further opening has the aforementioned contact area.

[0021] The opening and / or the further opening can be designed to correspond to the suspension structure and / or to be round, preferably circular, or polygonal, preferably rectangular or square. The advantageous purpose is thus that the suspension structure can be easily inserted through the opening into the fastening device or can be held in place and preferably blocked by the further opening. Furthermore, the fact that the opening is designed to correspond to the suspension structure advantageously ensures that the suspension structure or its suspension body fits into the opening in only one orientation, for example vertically, whereby the installation of the suspension structure in the fastening device is simplified and more secure. The opening is preferably larger than the further opening so that the suspension structure can be passed through the opening and cannot be passed through the further opening.The opening preferably has a diameter of 5 mm to 10 mm, particularly preferably 8.5 mm.

[0022] The further opening preferably has a diameter of 2 mm to 6 mm, particularly preferably 4.5 mm.

[0023] The fastening device can have at least two, preferably three or four fastening structures. This is particularly advantageous when heavier and / or larger objects or devices, such as a large-area luminaire, in particular a pendant luminaire, are to be fastened to a corresponding number of suspension structures via the fastening device. The plurality of fastening structures are preferably distributed (arranged) evenly over the fastening device so that, in particular, the weight of the fastening device and, if present, the weight of the luminaire connected to it can be distributed evenly across the corresponding number of suspension structures. In a particularly preferred exemplary embodiment, the plurality of fastening structures are formed in regions delimiting the fastening device, such as corner regions.This is particularly advantageous for good accessibility of the fastening structures.

[0024] The fastening device is preferably made of aluminum, in particular by an aluminum die-casting process. This allows for a lightweight fastening device while simultaneously maintaining sufficient strength. Alternatively or additionally, the at least one fastening structure can be formed integrally with the fastening device.

[0025] According to the invention, the invention relates to a luminaire housing comprising a fastening device as described above. The fastening device is preferably formed integrally with the luminaire housing; the luminaire housing and fastening device are preferably manufactured together using an aluminum die-casting process. Alternatively, the fastening device can also be detachably connected to the luminaire housing, for example, via a clip connection.

[0026] According to a further aspect, the invention relates to a luminaire, in particular a pendant luminaire, comprising a luminaire housing as described above and at least one illuminant, such as an LED, accommodated in the luminaire housing.

[0027] According to yet another aspect, the invention relates to a lighting system comprising a luminaire as described above and a suspension structure (for example in the form of a cable suspension with a suspension body provided in particular at the distal end of the cable suspension), wherein the suspension structure in the carrying position carries the fastening device and thus the luminaire, so that the luminaire is fastened to the suspension structure via the fastening device. 4. Description of a preferred embodiment:

[0028] The invention is described below by way of example with reference to the figures, which illustrate an advantageous embodiment of the invention. The figures show: Figure 1 a schematic plan view of a preferred embodiment of the fastening device according to the invention; Figure 2 a schematic perspective detailed view of a fastening structure of the Figure 1 shown fastening device; and Figure 3 a detailed view of the Figure 2 shown fastening structure in a top view.

[0029] Figure 1shows an example of a fastening device 1 according to a preferred embodiment. The fastening device 1 is provided for fastening a luminaire, in particular a pendant luminaire, or another suspended element, in particular an (electrical) device or even a suspended ceiling, to a suspension structure (suspension structure or suspension option) not shown in detail. The suspension structure usually hangs from a ceiling vertically or diagonally, for example at an angle of 45° to the vertical. The suspension structure preferably has a suspension body, provided in particular at the distal end of the suspension structure. For example, the suspension structure is designed in the form of a cable suspension. Preferably, the suspension body is designed as a nipple or sphere. Other geometries of the suspension body are also conceivable, for example suspension bodies with a polygonal (rectangular, square, etc.) shape.) or round (circular, elliptical, etc.) cross-section.

[0030] The fastening device 1 is preferably rectangular in plan view. However, the fastening device 1 can also have any other shape in plan view, for example, a polygonal (square, etc.) or round (circular, elliptical, etc.) shape.

[0031] The fastening device 1 has at least one fastening structure 2. The fastening device 1 can also have more than one fastening structure 2, i.e. at least two, preferably three or - as in Figure 1 clearly visible - four fastening structures 2. How Figure 1As can be clearly seen, the fastening structures 2 can be evenly distributed over the fastening device 1. For example, the fastening structures 2 are formed in regions delimiting the fastening device 1, such as corner regions 3. However, the fastening device 1 can also have only one fastening structure 2, which is then formed, for example, centrally in the fastening device 1. Only one fastening structure 2 is particularly advantageous in a spherical light.

[0032] In the following, with particular reference to the Figures 2 and 3 One of the fastening structures 2 is described as an example. The description of this fastening structure 2 applies analogously to the other fastening structure(s) 2, unless otherwise described.

[0033] The fastening structure 2 has an opening 4 through which the suspension structure (partially) or the suspension body of the suspension structure (completely) can be inserted into the fastening device 1. The opening 4 is preferably designed to correspond to the suspension structure, in particular to the suspension body, for example round, preferably circular or elliptical. However, the opening 4 can also be polygonal, in particular rectangular or square. The only important thing is that the suspension structure or its suspension body can be inserted into the fastening device 1 through the opening 4. The opening 4 preferably has a diameter of 5 mm to 10 mm, particularly preferably 8.5 mm. In other exemplary embodiments, in particular for particularly heavy objects or lights, the diameter can also be more than 10 mm.

[0034] A slot 5 is preferably directly connected to the opening 4, so that the suspension structure introduced into the fastening device 1 via the opening 4 can be moved via the slot 5 into a supporting position. The suspension structure can thus be moved along the slot 5, but cannot be moved out of the fastening device 1 via the slot 5. Preferably, the slot 5 is designed to be so wide that the suspension body, if present, and thus the suspension structure cannot be guided out of the fastening device 1 via the slot 5. The slot 5 is preferably designed to be constant in width along its direction of extension.

[0035] The suspension structure can thus be moved via the slot 5 into a supporting position in which the suspension structure supports the fastening device 1 in a suspended manner. The suspension structure preferably reaches the supporting position when the suspension structure comes into force-fitting and / or form-fitting contact with a (defined) contact area. In the exemplary embodiment shown in the figures, the suspension structure reaches the supporting position in particular when it reaches a further opening 6 formed with the fastening structure 2. In general, the supporting position is any position in which the suspension structure can support the fastening device in a suspended manner; the supporting position therefore does not include the opening 4 in particular. The further opening 6 is therefore also connected to the slot 5. The suspension structure, in particular its suspension body, can thus be held in the supporting position in particular via the geometry of the further opening 6.Preferably, the further opening 6 has the contact area. For example, the contact area is formed by the circumference of the further opening 6.

[0036] The further opening 6 preferably has a shape corresponding to the suspension structure, in particular the suspension body. For example, the further opening 6 is round, preferably circular, or polygonal, preferably rectangular or square. The further opening 6 is preferably smaller than the opening 4, so that the suspension structure, in particular its suspension body, cannot be passed through the further opening 6. It is particularly preferred if the further opening 6 has a diameter of 2 mm to 6 mm, for example 4.5 mm.

[0037] The slot 5 has a serrated section 51 which is designed to prevent movement of the suspension structure from the supporting position. In the exemplary embodiment shown in the figures, this is achieved in such a way that the serrated section 51 has a first partial section 51a and a second partial section 51b forming the serrated section 51 or the serrated shape of the section 51. The partial sections 51a, 51b are each preferably designed to run in a straight line. The first partial section 51a preferably runs in the direction of the supporting position or the further opening 6, i.e. is preferably (directly) connected to the further opening 6. The second partial section 51b preferably runs with an extension direction which points neither in the direction of the opening 4 nor in the direction of the supporting position or the further opening 6.The sections 51a, 51b extend in such a way that, when the suspension structure supports the fastening device 1 in the supporting position, i.e., when the suspension structure is provided in particular in the region of the further opening 6 or in the first section 51a, movement of the suspension structure from the first section 51a into the second section 51b and thus from the supporting position is prevented. This is achieved by selecting the angle between the sections 51a and 51b accordingly, for example, as an acute angle. According to the invention, this angle lies in a range of 20° to 70°, preferably in a range of 30° to 50°, for example, substantially 37°.

[0038] The first section 51a is preferably longer than the second section 51b. For example, the length of the first section 51a is a multiple of the length of the second section 51b; thus, the first section 51a is preferably elongated. In particular, the first section 51a can be twice or three times as long as the second section 51b. Thus, shocks and forces acting on the fastening device 1 can be absorbed particularly effectively by the first section 51a.

[0039] The slot 5 has at least one further serrated section 52 which is connected to the opening 4 and the serrated section 51, so that the suspension structure introduced into the fastening device 1 via the opening 4 can be moved into the carrying position via the further serrated section 52 and the serrated section 51. The further serrated section 52 has the effect that a movement of the suspension structure from the carrying position, i.e. in particular into the opening 4, can be prevented even better. In the exemplary embodiment shown in the figures, this is achieved in such a way that the further serrated section 52 has a (further) first partial section 52a and a (further) second partial section 52b forming the further serrated section 52 or the serrated shape of the section 52, wherein, as shown in the Figures 2 and 3As can be clearly seen, the (further) second subsection 52b is preferably the second subsection 51b. The subsections 52a, 52b are each preferably designed to run in a straight line. Alternatively, however, it can also be provided that the second subsection 51b is indirectly connected to the second subsection 52b. The (further) first subsection 52a is preferably (directly) connected to the opening 4.

[0040] It is preferred if the (further) first sub-section 52a and the (further) second sub-section 52b extend in such a way that, when the suspension structure supports the fastening device 1 in the carrying position, a movement of the suspension structure from the (further) second sub-section 52b into the (further) first sub-section 52a and thus from the carrying position or into the opening 4 can be prevented. For this purpose, the sub-sections 52a, 52b preferably extend at a defined, in particular acute angle. For example, the defined angle between the sub-sections 52a and 52b lies in a range of 70° to 90°. Preferably, the aforementioned angle is substantially 80°. The sub-sections 52a, 52b are preferably of substantially equal length.

[0041] As in Figure 3As can be clearly seen, the following extension of the sections 51a, 51b, 52a, 52b, starting from the opening 4, preferably results: The section 52a leads away from the opening 4, adjoining the section 52a, the section 51b or 52b leads away from the further opening 6, and adjoining the section 51b or 52, the section 51a leads (in a straight line) to the further opening 4. The jagged sections 51, 52 thus form a type of labyrinth, zigzag, or lightning guide, which particularly effectively prevents or impedes the suspension structure from moving out of the supporting position, i.e. in particular, an unintentional movement of the suspension structure into the opening 4.

[0042] The slot 5 can also have more than one further serrated section 52, for example two or three further serrated sections, so that, for example, a first sub-section of a further serrated section forming the respective serration is the second sub-section of the serration of the next further serrated section, etc. The more serrated sections or changes in direction the slot 5 has, the better the suspension structure can be secured in the supporting position.

[0043] In addition to the serrated design of the slot as described above, the slot 5 is also designed such that the suspension structure can be driven into the carrying position, i.e. in particular into the further opening 6, by the weight of the fastening device 1. In the embodiment shown in the figures, this is achieved in that, in a state in which the suspension structure supports the fastening device 1 in the carrying position, the slot 5 extends such that the contact area with which the suspension structure is in contact in the carrying position in order to support the fastening device 1 is arranged higher than the opening 4. As in particular the Figure 2As can be clearly seen, in the exemplary embodiment shown in the figures this is preferably effected in such a way that the further opening 6 is arranged higher than the opening 4. This means that if the further opening 6 provides the contact area, the contact area is preferably arranged higher than the opening 4 on the side of the contact area.

[0044] For example, in a state in which the suspension structure supports the fastening device 1 in the carrying position, the slot 5 can extend obliquely to the horizontal, so that, in particular, the aforementioned height difference between opening 4 and the further opening 6 is provided. In this way, the suspension structure can move relative to the fastening device 1 by the weight of the fastening device 1 and be driven into the carrying position. Figure 2As can be clearly seen, the slot 5 preferably runs at an angle of 5° to 15°, particularly preferably at an angle of 10° to the horizontal, when the suspension structure supports the fastening device 1 in the carrying position. Preferably, the fastening structure 2 has a surface 7 which is inclined with respect to the (main extension direction of the) fastening device 1 and in which the slot 5 is formed, so that the slot 5 runs obliquely to the horizontal when the suspension structure supports the fastening device 1 in the carrying position. The opening 5 is thus provided at a lower region of the inclination of the surface 7, with the further opening 6 being provided at a higher region of the inclination of the surface 7; the inclination of the surface 7 therefore leads from the opening 5 to the further opening 7.

[0045] The fastening device 1 is preferably made of aluminum. Alternatively or additionally, however, it can also be provided that the fastening device 1 is made of a different material, for example, plastic. An aluminum die-casting process is preferably used to produce the fastening device 1. The fastening structure 2 is preferably integral with the fastening device 1, i.e., in particular, made of a single cast with the fastening device 1.

[0046] As in particular the Figure 2As can be clearly seen, the slot 5 preferably has both the jagged, labyrinthine or lightning-shaped design described above and also the design such that the suspension structure can be driven into the carrying position by the weight of the fastening device 1. In this way, particularly good securing of the suspension structure in the carrying position can be ensured. In order to sufficiently secure the suspension structure in the carrying position without separately provided securing means, it is, however, already sufficient according to the invention if the slot 5 only runs in a jagged shape as described above or if the slot 5 is only designed such that the suspension structure can be driven into the carrying position by the weight of the fastening device 1.

[0047] The fastening device 1 can be part of a luminaire housing or partially form the luminaire housing. The fastening device 1 can have structures over which parts of the luminaire housing or the luminaire, in particular components for operating the luminaire, such as an operating device, can be accommodated. It is particularly preferred if the fastening device 1 is formed integrally with the luminaire housing. Alternatively, the fastening device 1 can also be detachably connected to the luminaire housing, for example via appropriate fastening means such as a clip connection.

[0048] However, the present invention is not limited to the foregoing preferred embodiment as long as it is encompassed by the subject matter of the following claims.
