Description

[0001] The present invention relates to a holding device for a mounting frame of a recessed luminaire for mounting in a mounting opening of a ceiling or wall, according to the preamble of claim 1. The invention further relates to a mounting frame equipped with several such holding devices, and to a recessed luminaire equipped with such a mounting frame.

[0002] A holding device of this type is known, for example, from EP 2 893 248 B1 and comprises a straight rail having a longitudinal direction, a transverse direction, and a vertical direction, as well as a carriage that is adjustably mounted on the rail in the longitudinal direction. The rail has a longitudinally extending guide on each of its two longitudinal sides facing away from each other in the transverse direction, while the carriage is equipped with two complementary counter-guides that are coupled to the guides for the guided longitudinal displacement of the carriage along the rail. Furthermore, the carriage is adjustable between a holding position, an intermediate position, and an assembly position. In the holding position, the carriage is located in a first longitudinal section of the rail. In the intermediate position, the carriage is located in a second longitudinal section of the rail, facing away from the first longitudinal section.In the assembly position, the carriage is located in the second longitudinal section and is pivoted about a pivot axis relative to the rail. In the known holding device, the pivot axis extends parallel to the transverse direction and is defined by two cylindrical pins that project from the carriage and form part of the counter-guides. The pins engage in complementary longitudinal grooves, which form part of the guides and are located on the rail.

[0003] Several such holding devices can be provided on a mounting frame that can be inserted into a mounting opening when the carriages are in the mounting position, and that is held against an opening edge surrounding the mounting opening when the carriages are moved into their holding position. A recessed luminaire equipped with such a mounting frame can be attached to the wall or ceiling using this mounting frame.

[0004] In order for an installer (male / female / diverse) to move the carriages of the holding devices from the assembly position to the intermediate position and then to the holding position when the mounting frame is inserted into the mounting opening, the installer must reach through the mounting frame and relatively deep into the mounting opening, resulting in a relatively large insertion depth. For the respective carriage to pivot around the pivot axis of the known holding device, which runs parallel to the transverse direction, the carriage must be located at the end of the rail projecting into the mounting opening. The installer must therefore grasp the end of the rail projecting into the mounting opening to move the carriage from the assembly position to the intermediate position and then into the holding position. A large insertion depth makes handling the holding frame more difficult during assembly.

[0005] The present invention addresses the problem of providing an improved or at least a different embodiment for such a holding device, or for a mounting frame equipped therewith, or for a recessed luminaire equipped therewith, which enables simple and reliable mounting of the recessed luminaire.

[0006] This problem is solved according to the invention by the subject matter of the independent claim. Advantageous embodiments are the subject matter of the dependent claims.

[0007] The invention is based on the general concept of aligning or configuring the rail and the carriage in such a way that the pivot axis, around which the carriage can pivot relative to the rail between the intermediate position and the mounting position, extends parallel to the longitudinal direction. This allows the carriage to be manually gripped laterally to the side of the rail and pivoted around the pivot axis relative to the rail. With the holding device attached to the mounting frame and the mounting frame inserted into the mounting opening, the installer only needs to reach axially into the mounting opening enclosed by the mounting frame until they can access the respective carriage laterally. This results in a shallower reach into the mounting opening than with a conventional holding device, where the carriage pivots around a pivot axis running parallel to the transverse direction.This significant reduction in the insertion depth for actuating the carriage considerably improves the handling of the holding device, which facilitates the installation of the recessed light.

[0008] In the present context, a "configuration" is synonymous with a "design", so that the phrase "configured so that" is synonymous with the phrase "designed so that".

[0009] The pivotability of the carriage relative to the rail about the pivot axis running parallel to the longitudinal direction is achieved in the holding device presented here by having one (or first) guide extend from the first longitudinal section to the second longitudinal section, while the other (or second) guide extends only within the first longitudinal section. The first (or first) counter-guide and the first guide are configured such that the carriage can pivot about the pivot axis relative to the rail in the intermediate position. In other words, the pivot axis running parallel to the longitudinal direction is defined by the first guide and the first counter-guide. Specifically, the first guide and the first counter-guide form a pivot bearing for the carriage on the rail. The other (or second) counter-guide is coupled to the second guide in the holding position and decoupled from the second guide in the intermediate position.By decoupling the second counter-guide from the second guide in the intermediate position, the carriage can be pivoted around the pivot axis relative to the rail by means of the first guide and the first counter-guide, thus allowing it to be adjusted between the intermediate position and the assembly position. When the carriage is in the intermediate position, it can be moved longitudinally along the rail, with the second guide and the second counter-guide then coupled to improve the longitudinal guidance of this adjustment. This allows the carriage to be moved longitudinally between the holding position and the intermediate position.

[0010] An advantageous embodiment includes a first guide rod that is connected to the rail via a web on each longitudinal side and extends in a straight line in the longitudinal direction. The web is interrupted in the second longitudinal section, such that a gap is formed between the first guide rod and the rail in this second longitudinal section. Furthermore, the first counter-guide is configured to encompass the first guide rod by more than 180° and less than 360°, such that the first counter-guide has a gap extending continuously in the longitudinal direction. This gap is dimensioned such that, when the carriage is moved longitudinally, the web penetrates the gap and passes through it transversely to the longitudinal direction. The first counter-guide is thus designed as a slotted sleeve.The gap in the sleeve forms a longitudinal slot in which the web can move longitudinally, allowing the carriage to slide along the rail. Since the first counter-guide engages the first guide rod, pivoting between the carriage and the rail about the pivot axis is also achieved. The pivot axis then runs coaxially with the guide rod. The gap provided in the web in the second longitudinal section allows the first counter-guide to move into the gap during pivoting, thus enabling pivoting between the carriage and the rail. Because the first counter-guide engages the first guide rod by more than 180°, preferably by at least 270°, it is held securely against loss on the first guide rod transversely to the longitudinal direction.

[0011] According to an advantageous embodiment, the second guide can have a second guide rod which is connected to the rail via a web on the respective longitudinal side of the rail and extends in a straight line in the longitudinal direction. Unlike the first guide rod, the second guide rod extends only in the first longitudinal section. The second counter-guide surrounds the second guide rod by more than 180° and less than 360°, so that the second counter-guide also has a gap that extends continuously in the longitudinal direction and is dimensioned such that, when the carriage is moved longitudinally, the web penetrates the gap and passes through the gap transversely to the longitudinal direction. Thus, in the first longitudinal section, the second guide and the second counter-guide are constructed almost identically to the first guide and the first counter-guide.Since the second guide rod only extends in the first longitudinal area, decoupling between the second counter-guide and the second guide inevitably occurs in the second longitudinal area as soon as the second counter-guide is freed from the second guide rod when moving in the longitudinal direction.

[0012] The respective gap is located in the circumferential direction of the respective counter guide, which runs around the longitudinal direction, and represents a longitudinal slot of the sleeve-shaped counter guide.

[0013] In another advantageous embodiment, the rail can have an opening and a slot penetrating the rail in the transverse direction between the guides. The opening is formed in the second longitudinal region, while the slot extends longitudinally from the first longitudinal region into the opening. In other words, the slot transitions seamlessly into the opening. The opening is larger in the transverse direction than the slot. The carriage now has a locking element between the counter-guides, which is connected to the carriage via a connecting web and which is larger in the transverse direction than the connecting web.Furthermore, the opening, the slot, the locking element, and the connecting web are now coordinated such that when the carriage is pivoted around its pivot axis between the intermediate position and the mounting position, the locking element can be adjusted through the opening. Similarly, when the carriage is moved longitudinally between the intermediate position and the holding position, the connecting web within the slot is longitudinally adjustable, penetrating the slot and positioning the locking element on the side of the rail facing away from the carriage. The locking element, guided in the slot, creates an additional positive fit between the carriage and the rail, improving the support between them. The positioning of the locking element here is equivalent to a positive-locking hold transverse to the longitudinal direction between the carriage and the rail by means of the shearing element and the connecting web.

[0014] According to an advantageous embodiment, the gap of the first counter-guide can be positioned such that the first counter-guide can be attached to and removed from the first guide rod in the longitudinal direction when the locking element is moved out of the opening by pivoting the slide about the pivot axis, so that the slide can be mounted on and removed from the rail. This results in particularly simple mounting and dismounting of the slide on the rail.

[0015] An advantageous configuration is one in which the first counter-guide has a constriction at a longitudinal end facing away from the first longitudinal section of the rail, in the gap with respect to a circumferential direction in which the first counter-guide engages the first guide rod. This constriction is, for example, in the form of a protruding nose in the circumferential direction of the counter-guide, and is smaller in this circumferential direction than a web section that limits the gap between the rail and the first guide rod on a side facing away from the first longitudinal section. Alternatively, it can also be provided that a web section that limits the gap on a side facing away from the first longitudinal section is larger than the gap of the first counter-guide with respect to a circumferential direction in which the first counter-guide engages the first guide rod.These two alternative embodiments ensure that the first counter-guide can only be attached to or removed from the first guide rod against increased resistance in the longitudinal direction. In particular, this may require elastic deformation of the first counter-guide. In this way, a locking mechanism for the carriage on the rail is created in the assembly position, as the carriage cannot fall off the first guide rod on its own.

[0016] According to another embodiment, a detent contour can be formed on one of the rail and the slide, featuring several longitudinally adjacent detent steps. On the other of the rail and the slide, a counter-detent contour complementary to the detent steps can be formed, which has at least one detent lug that interacts with the detent steps to maintain the relative position between the slide and the rail with respect to the longitudinal direction. The detent contour with multiple longitudinally adjacent detent steps defines several longitudinal positions between the rail and the slide in which the slide is held against the rail. This configuration is particularly advantageous in conjunction with a mounting frame, since the different detent steps allow the respective holding device to be easily adapted to varying wall thicknesses of an opening edge surrounding the mounting opening, thus enabling the mounting frame to be secured to it.

[0017] A preferred embodiment features a detent contour formed on the rail, with detent steps located on both sides of the slot on a side of the rail facing the carriage in the holding position. In contrast, the counter-detent contour is formed on the carriage, with at least one such detent lug located on a side of the carriage facing the locking element. The detent contour and the counter-detent contour interact to position the carriage relative to the rail by means of a positive locking action extending transversely to the longitudinal direction. The locking element ensures a secure and, in particular, pre-tensioned engagement between the detent steps and the detent lugs, thereby securing the respective detent position.

[0018] According to another embodiment, the slide can have a pressure area that, in the holding position, projects vertically away from the rail. With the aid of this pressure area, when the holding devices are used on a mounting frame, stable support of the respective slide can be achieved at the opening edge. A particularly advantageous embodiment is one in which the pressure area is connected to the slide via a spring section, which can be elastically designed. In conjunction with the locking mechanism described above, which has several locking positions in the longitudinal direction, the mounting frame can be fixed at the respective opening edge by clamping the opening edge between the pressure areas of the holding devices and the mounting frame with respect to the longitudinal direction.At the same time, this achieves a clean installation with a mounting frame that fits snugly all around the edge of the opening.

[0019] A mounting frame according to the invention, designed for mounting a recessed luminaire in a mounting opening in a ceiling or wall framed by an opening edge, comprises a frame body with a flange for bearing against an outer surface of the opening edge facing away from the mounting opening, and several retaining devices of the type described above, which are arranged circumferentially distributed around the frame body. The flange extends circumferentially around the frame body, rotating about a longitudinal center axis of the frame body. Preferably, the flange extends completely around the frame body in the circumferential direction. The respective rail can then be rigidly connected to the frame body with its longitudinal direction aligned parallel to the longitudinal center axis. This allows the carriages to be adjusted parallel to each other along the rails.The mounting frame can be inserted into the mounting opening once the slides are in their mounting position. The mounting frame then has its largest cross-section in the area of ​​the flange, perpendicular to the longitudinal center axis. When the slides are in their holding position and are supported against an inner surface of the opening facing the mounting opening, the mounting frame, correctly inserted into the mounting opening, rests with its flange against the outer edge of the opening and is secured there. In In the holding position, the cross-section of the mounting frame in the area of ​​the holding devices is at least larger than the cross-section of the mounting opening and preferably also larger than the cross-section in the area of ​​the flange. This allows the mounting frame to be positively supported against the edge of the opening by means of the slides. The edge of the opening is then clamped parallel to the longitudinal center axis between the flange and the slides.

[0020] According to a particularly advantageous embodiment, the respective slide can be designed separately from the frame body, thus forming a separate component, and can be attached to the frame body by means of a clip or snap connection. This allows the frame body and slide to be manufactured separately, for example as castings and / or from plastic. However, an integrated design is also conceivable, in which the slides are integrally formed on the frame body.

[0021] According to another embodiment, the frame body can be closed in the circumferential direction. This allows the frame body to have, for example, a polygonal, rectangular, round, or circular cross-section. In particular, the frame body's cross-section is adapted to the respective mounting opening, or vice versa.

[0022] A recessed luminaire according to the invention is designed for installation in a mounting opening in a ceiling or wall, the opening being framed by an edge. For this purpose, the recessed luminaire is equipped with a mounting frame of the type described above. It also has a light source holder that is directly or indirectly connected to the mounting frame. At least one light source, which in particular may comprise at least one light-emitting diode, can be arranged on this light source holder. The mounting frame makes it particularly easy to install the recessed luminaire in a mounting opening. It may be provided that a detachable connection is provided between the mounting frame and the light source holder, designed such that the mounting frame can first be installed in the mounting opening or attached to the edge of the opening without the light source holder.The light source holder can then be attached to the mounting frame already fixed at the edge of the opening. Such a detachable attachment can be achieved, for example, by a snap-fit ​​mechanism, a bayonet fitting, or a screw thread.

[0023] According to an advantageous embodiment, the recessed luminaire can have a reflector that connects the mounting frame to the light source holder. In particular, the aforementioned detachable fastening between the light source holder and the mounting frame can now be formed between the reflector and the mounting frame, so that the reflector can be detachably attached to the mounting frame. The light source holder can, in turn, be permanently or detachably attached to the reflector.

[0024] According to another advantageous embodiment, the recessed luminaire can have a heat sink, in particular with cooling fins, which is connected to the light source carrier in a heat-transferring manner.

[0025] Further important features and advantages of the invention will become apparent from the dependent claims, the drawings and the associated description of the figures based on the drawings.

[0026] It is understood that the features mentioned above and those to be explained below can be used not only in the combinations specified, but also in other combinations or individually, without departing from the scope of the invention as defined by the claims. Components of a higher-level unit, such as a device, apparatus, or arrangement, mentioned above and those to be mentioned below, which are designated separately, can form separate parts or components of this unit or be integral areas or sections of this unit, even if this is depicted differently in the drawings.

[0027] Preferred embodiments of the invention are shown in the drawings and are explained in more detail in the following description, wherein identical reference numerals refer to identical or similar or functionally identical components.

[0028] They show, schematically, Figure 1 is an isometric view of a recessed luminaire with a mounting frame having several holding devices, Figure 2 is a slightly isometric view of a holding device in a holding position, Figure 3 is a slightly isometric view of the holding device in an intermediate position, Figure 4 is a slightly isometric view of the holding device in a mounting position, Figure 5 is an isometric sectional view of the recessed luminaire.

[0029] According to the Figure 1 and 5 A recessed luminaire 1 comprises a mounting frame 2, a light source holder 3 and at least one Figure 5The recessed luminaire 1 is indicated by a light source 4, which is arranged on the light source holder 3. The light source 4 can have one or more light-emitting diodes as well as power electronics. The recessed luminaire 1 is also equipped with a reflector 5, which connects the mounting frame 2 to the light source holder 3. Furthermore, the recessed luminaire 1 has a heat sink 6, which is equipped with several cooling fins 7 and which is held on the light source holder 3 or on the reflector 5 and is connected to the light source 4 for heat transfer. The recessed luminaire 1 is designed for installation in a Figure 5A visible mounting opening 8 is provided, which is formed in a ceiling 9 or wall 10 and is framed by an opening edge 11. The mounting frame 2 serves to secure the recessed luminaire 1 to this opening edge 11. For this purpose, the mounting frame 2 is equipped with several retaining devices 12, which are arranged around the mounting frame 2 in a circumferential direction U. The circumferential direction U of the mounting frame 2 runs around a longitudinal center axis L of the recessed luminaire 1 or of the mounting frame 2.

[0030] According to the Figures 1 to 5 Each retaining device 12 has a straight rail 13 that is configured in a straight and flat manner and defines a longitudinal direction X, a transverse direction Y, and a vertical direction Z that are perpendicular to each other. In the assembled state, with the retaining devices 12 attached to the mounting frame 2, the longitudinal directions X of the retaining devices 12 extend according to the Figure 1 and 5 parallel to the longitudinal center axis L of the mounting frame 2.

[0031] Each holding device 12 is also equipped with a carriage 14, which is adjustable in the longitudinal direction X on the respective rail 13. The respective rail 13 has a length extending in the longitudinal direction X, a width extending in the transverse direction Y, and a thickness extending in the vertical direction Z. For the elongated and flat rails 13, the thickness is less than the width, which in turn is less than the length.

[0032] Each rail 13 has a guide 15 on each of its two longitudinal sides, facing away from each other in the transverse direction Y, and extending in the longitudinal direction X. Each carriage 14 has two counter-guides 16, which are designed to complement the guides 15. The counter-guides 16 are coupled to the guides 15 and interact with them to enable guided longitudinal movement of the carriage 14 in the longitudinal direction X along the rail 13. The two guides 15 form a first guide 15a and a second guide 15b. The two counter-guides 16 form a first counter-guide 16a, which interacts with the first guide 15a, and a second counter-guide 16b, which interacts with the second guide 15b.

[0033] The sled is 14 between a in Figure 2 shown holding position HS, one in Figure 3 shown intermediate position ZS and one in Figure 4The MS mounting position shown is adjustable relative to the respective rail 13. For illustrative purposes, see in Figure 1 In the three holding devices 12 shown, the slides 14 are shown in the three different positions. In the Figure 1 With the holding device 12 facing the viewer, the slide 14 is adjusted to the MS mounting position. In the Figure 1 The carriage 14 is moved into the holding position HS by the holding device 12 arranged on the left. In the Figure 1 The carriage 14 is adjusted to the intermediate position ZS by the holding device 12 arranged on the right. In the sectional view of the Figure 5 Only two of the three holding devices 12 are visible. In the case of the Figure 5 The carriage 14 is in the holding position HS in the holding device 12 arranged on the right, shown in section. Figure 5The carriage 14 is in the MS mounting position on the holding device 12, which is turned away from the viewer and partially concealed by the light source carrier 3 or the heat sink 6.

[0034] Figure 4 The figure does not show the carriage 14 fully pivoted into the MS mounting position, but rather a pivot position MS' that results from the transition from the intermediate position ZS to the MS mounting position and which can be used, for example, to mount the carriage 14 on the rail 13, as will be explained in more detail below. The carriage 14 fully pivoted into the MS mounting position is shown in Figure 1 at the front holding device 12 facing the viewer and in Figure 5 recognizable at the rear holding device 12, which faces away from the viewer.

[0035] According to the Figures 1 to 5In the holding position HS, the carriage 14 is located in a first longitudinal section 17 of the rail 13, which, when the holding device 12 is attached to the mounting frame 2, faces the mounting frame 2. In the intermediate position ZS, the carriage 14 is located in a second longitudinal section 18 of the respective rail 13, facing away from the first longitudinal section 17. This second longitudinal section 18 also faces away from the mounting frame 2 when the holding device 12 is attached to the mounting frame 2. In the mounting position MS, the respective carriage 14 is located in the second longitudinal section 18 and is pivoted about a pivot axis S relative to the rail 13. The rail 13 and carriage 14 are configured such that the pivot axis S extends parallel to the longitudinal direction X.

[0036] Furthermore, the holding devices 12 are configured such that the first guide 15a extends from the first longitudinal section 17 to the second longitudinal section 18, while the second guide 15b extends only within the first longitudinal section 17 and is therefore significantly shorter than the first guide 15a with respect to the longitudinal direction X. In the embodiments shown here, the first guide 15a extends over the entire length of the rail, while the second guide 15b extends only about half the length of the rail. The first counter-guide 16a and the first guide 15a are configured such that the carriage 14 can be pivoted about the pivot axis S relative to the rail 13 in the intermediate position ZS. The second counter-guide 16b is coupled to the second guide 15b in the holding position HS and decoupled from the second guide 15b in the intermediate position ZS.Accordingly, in the holding position HS, the two counter guides 16 are coupled to the two guides 15 to enable the guided longitudinal displacement of the carriage 14 relative to the rail 13, in order to adjust the carriage 14 between the holding position HRS and the intermediate position ZAS. In the intermediate position ZS and in the assembly position MS, however, the second counter guide 16b is decoupled from the second guide 15b, while the first counter guide 16a remains coupled to the first guide 15a and also defines a pivot bearing, so that the carriage 14 can be pivoted about the pivot axis S relative to the carriage 13 between the intermediate position ZS and the assembly position MS.

[0037] The first guide 15a has a first guide rod 19, which is connected to the rail 13 on the respective longitudinal side of the rail 13 via a first web 20 and extends in the longitudinal direction X. The first guide rod 19 is essentially cylindrical. In the examples shown here, the first guide rod 19 has a C-shaped cross-sectional profile.

[0038] The first guide rod 19 and the first web 20 extend over the entire length of the rail, with the first guide rod 19 extending continuously, while the first web 20 is interrupted in the second longitudinal section 18, such that a gap 21 is formed between the first guide rod 19 and the rail 13 in the second longitudinal section 18. The first counter-guide 16a surrounds the first guide rod 19 by more than 180° and less than 360°. Consequently, the first counter-guide 16a has a first gap 22 in its circumferential direction V around the pivot axis S. The first counter-guide 16a is essentially hollow cylindrical and has a C-shaped cross-sectional profile.This first gap 22 extends continuously through the first counter-guide 16a in the longitudinal direction X and is dimensioned such that the first web 20 penetrates into the first gap 22 when the slide 14 is moved longitudinally in the longitudinal direction X and penetrates the first gap 22 transversely to the longitudinal direction X. This penetration and penetrating is described in . Figure 2 recognizable.

[0039] The second guide 15b can have a second guide rod 23, which is connected to the rail 13 on its respective longitudinal side via a second web 24 and extends in the longitudinal direction X. Unlike the first guide rod 19, the second guide rod 23 extends only in the first longitudinal section 17, i.e., only about half the length of the rail. The second counter-guide 16b is structurally identical but configured as a mirror image of the first counter-guide 16a. Accordingly, the second counter-guide 16b encompasses the second guide rod 23 by more than 180° and by less than 360°. As a result, the second counter-guide 16b also has a second gap 25, which extends continuously through the second counter-guide 16b in the longitudinal direction X and is dimensioned such that the second web 24 penetrates into the second gap 25 when the carriage 14 is moved longitudinally in the longitudinal direction X and penetrates the second gap 25 transversely to the longitudinal direction X.This intrusion and penetration is also in . Figure 2 recognizable.

[0040] The dimensioning of the second guide rod 23 ensures that the second counter-guide 16b is released from the second guide rod 23 in the intermediate position ZS. Consequently, the carriage 14 is no longer held against the second guide 15b via the second counter-guide 16b, allowing the carriage 14 to pivot about the pivot axis S relative to the rail 13. Figure 3 An axial gap 26 is discernible, which forms between the second guide 15b or the second guide rod 23 and the second counter guide 16b when the slide 14 reaches the intermediate position ZS.

[0041] In the embodiments shown here, the rail 13 has an opening 27 penetrating the rail 13 in the transverse direction Y between the two guides 15, located in the second longitudinal section 18. The rail 13 is also equipped with a slot 28 penetrating the rail 13 in the transverse direction Y between the guides 15, extending in the longitudinal direction X from the first longitudinal section 17 into the opening 27. The opening 27 is larger in the transverse direction Y than the slot 28. The carriage 14 has a locking element 29 in the transverse direction Y between the counter guides 16, which is connected to the carriage 14 via a connecting web 30. The locking element 29 is larger in the transverse direction Y than the web 30. The transverse direction Y of the carriage 14 coincides with the transverse direction Y of the carriage 13, at least in the holding position HS.Furthermore, the opening 27, the slot 28, the locking element 29, and the connecting web 30 are coordinated such that, in the intermediate position ZS, the locking element 29 can be adjusted by pivoting the slide 14 through the opening 27, and that when the slide 14 is moved longitudinally between the intermediate position ZS and the holding position HS, the connecting web 30 is longitudinally adjustable in the slot 28, thereby penetrating the slot 28 in the vertical direction Z, and the locking element 29 is positioned on a side of the rail 13 facing away from the slide 14. Accordingly, the slide 13 is in the holding position HS according to... Figure 2 arranged between the slide 14 and the locking element 29.

[0042] According to a preferred embodiment, the first gap 22 of the first counter-guide 16a is dimensioned and positioned such that the first counter-guide 16a can be attached to and removed from the first guide rod 19 in the longitudinal direction X when the locking element 29 is moved out of the opening 27 by pivoting the slide 14 about the pivot axis S and the first gap 22 is aligned with the web 21 in the longitudinal direction X, so that the slide 14 can be mounted on and removed from the rail 13. For example, the slide 14 can be mounted in the Figure 4 shown swivel position MS', which is between the intermediate position ZS and the one in the Figure 1 and 5 Remove from rail 13 when the MS mounting position is shown.

[0043] The first counter-guide 16a can have a narrowing (not visible here) at a longitudinal end facing away from the first longitudinal section 17 in the first gap 22. This narrowing is smaller than a web section 20' of the first web 20 that borders the gap 21 on a side facing away from the first longitudinal section 17. Alternatively, this web section 20' of the first web 20, which borders the gap 21 on the side facing away from the first longitudinal section 17, can be larger than the first gap 22 of the first counter-guide 16a. In this way, a locking mechanism is formed between the slide 14 and the rail 13.

[0044] According to the Figure 1 and 5A detent contour 31 can be formed on the rail 13, which has several detent steps 32 adjacent in the longitudinal direction X. Complementarily, the slide 14 has a counter-detent contour 33, which has at least one detent lug 34 that interacts with the detent steps 32 to maintain a relative position between the slide 14 and the rail 13 with respect to the longitudinal direction X. The detent contour 31 and the detent steps 32 are located on one side of the rail 13 that faces the slide 14 in the holding position HS. The detent steps 32 extend on both sides of the slot 28. The counter-detent contour 33 and the respective detent lug 34 are located on one side of the slide 14 that faces the rail 13 in the holding position HS. They are thus on the same side as the locking element 29 and face the locking element 29.

[0045] According to the Figures 1 to 5The slide 14 has a pressure area 35 which, in the holding position HS, projects away from the rail 13 in the vertical direction Z. Advantageously, the slide 14 also has a preferably elastic spring area 36, ​​via which the pressure area 35 is connected to the slide 14. In the examples shown, the slide 14 is stiffened by means of lateral cheeks 43.

[0046] According to the Figure 1 and 5The mounting frame 2 has a frame body 37 with a flange 38 configured such that the frame body 37 can contact an outer surface 39 of the opening rim 11 facing away from the mounting opening 8 via the flange 38. Several retaining devices 12 are arranged on the frame body 37 in the circumferential direction U. In the examples shown, exactly three retaining devices 12 are arranged on the frame body 37. It is clear that, depending on the geometry of the mounting frame 2, two, four, or more retaining devices 12 can also be used. The flange 38 extends around the longitudinal center axis L in the circumferential direction U along the frame body 37, forming an edge projecting radially with respect to the longitudinal center axis L. The retaining devices 12 are arranged on the frame body 37 such that their longitudinal direction X extends parallel to the longitudinal center axis L.

[0047] To insert the mounting frame 2 into the mounting opening 8, the slides 14 of the holding devices 12 are adjusted to their mounting position MS. In the mounting position MS, the slides 14 do not form an obstruction that would hinder the insertion of the mounting frame 2 into the mounting opening 8. With the mounting frame 2 inserted into the mounting opening 8, the slides 14 have moved past the opening edge 11, are located within the mounting opening 8, and can be pivoted into the intermediate position ZS and then moved into the holding position HS. The mounting frame 2, correctly inserted into the mounting opening 8, then rests with its flange 28 against the outer side 39 of the opening edge 11 and is secured to the opening edge 11 as soon as the slides 14 assume their holding position HS and are supported against an inner side 40 of the opening edge 11 facing the mounting opening 8. Figure 5The opening edge 11 is then clamped parallel to the longitudinal center axis L between the flange 38 and the respective slide 14.

[0048] The slides 13 can form separate components with respect to the frame body 37 and can, for example, be attached to the frame body 37 by means of a snap-fit ​​connection 41. The snap-fit ​​connection 41 has two spring-elastic locking arms formed on the rail 13 in the vertical direction Z, with locking lugs and corresponding locking openings formed on the frame body 37. The frame body 37 runs continuously in the circumferential direction U and, in the embodiments shown here, has a circular cross-section. It is clear that other cross-sections for the frame body 37 are also possible, namely, in particular, other round, polygonal, or rectangular cross-sections.

[0049] For mounting the recessed luminaire 1, it may be advantageous to connect the mounting frame 2 to the other components of the recessed luminaire 1 via a detachable connection 42. The detachable connection 42 can, for example, be formed between the mounting frame 2 and the reflector 5. The detachable connection 42 can be, for example, a snap-fit ​​connection or a bayonet fitting.
