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 also relates to a mounting frame equipped with a plurality of such holding devices, as well as to a recessed luminaire equipped with such a mounting frame.

[0002] A generic holding device is known, for example, from EP 2 893 248 B1 and has a straight rail having a longitudinal direction, a transverse direction, and a vertical direction, as well as a carriage that is attached to the rail so that it can be adjusted in the longitudinal direction. The rail has a guide running in the longitudinal direction on each of two long sides facing away from each other in the transverse direction, while the carriage is equipped with two counter-guides that are complementary to the guides and are coupled to the guides for the guided longitudinal displacement of the carriage in the longitudinal direction 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 region of the rail. In the intermediate position, the carriage is located in a second longitudinal region of the rail facing away from the first longitudinal region.In the assembly position, the carriage is located in the second longitudinal section and is pivoted relative to the rail about a pivot axis. In the known holding device, the pivot axis extends parallel to the transverse direction and is defined by two cylindrical pins that protrude from the carriage and form components of the counter-guides. The pins engage in complementary longitudinal grooves that form components of the guides and are formed on the rail.

[0003] Several such holding devices can be provided on a mounting frame, which can be inserted into a mounting opening when the slides are in the mounting position and which is held on an opening edge surrounding the mounting opening when the slides 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 a fitter (male / female / diverse) to be able to move the slides of the holding devices from the mounting position to the intermediate position and then into the holding position when the mounting frame is inserted into the mounting opening, the fitter must reach through the mounting frame and relatively deeply into the mounting opening with the known holding devices, which results in a relatively large depth of engagement in the mounting opening. In order for the respective slide to be able to pivot about the pivot axis of the known holding device, which runs parallel to the transverse direction, the slide must be located at the end of the rail that projects into the mounting opening. The fitter must therefore grasp the end of the rail that projects into the mounting opening in order to move the slide from the mounting position to the intermediate position and then adjust it to the holding position. A large depth of engagement 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 installation 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 idea of ​​coordinating or configuring the rail and the carriage in such a way that the pivot axis around which the carriage can be pivoted relative to the rail between the intermediate position and the mounting position extends parallel to the longitudinal direction. This measure enables the carriage to be manually gripped at 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 with the mounting frame inserted into the mounting opening, the respective fitter only has to reach axially into the mounting opening enclosed by the mounting frame until they can reach the respective carriage from the side. The depth of engagement in the mounting opening is therefore less than with a conventional holding device in which the carriage pivots around a pivot axis running parallel to the transverse direction.This significant reduction in the depth of engagement for operating the slide significantly improves the handling of the holding device, which facilitates the installation of the recessed luminaire.

[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 in that one or first guide extends from the first longitudinal region to the second longitudinal region, while the other or second guide extends only in the first longitudinal region. The one or first counter-guide and the first guide are now configured such that the carriage can be pivoted 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. In particular, 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 about the pivot axis relative to the rail using the first guide and the first counter-guide, and thus adjusted between the intermediate position and the mounting 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 coupled to improve the longitudinal guidance of this longitudinal adjustment. This allows the carriage to be moved longitudinally between the holding position and the intermediate position.

[0010] An advantageous embodiment is one in which the first guide has a first guide rod which is connected to the rail on the respective long side of the rail via a web and which extends straight in the longitudinal direction. The web is interrupted in the second longitudinal region such that a gap is formed in the second longitudinal region between the first guide rod and the rail. Furthermore, the first counter-guide is configured such that it engages around the first guide rod by more than 180° and by less than 360° such that the first counter-guide has a gap which extends continuously in the longitudinal direction. This gap is dimensioned such that the web penetrates into the gap when the carriage is displaced longitudinally in the longitudinal direction and penetrates the gap transversely to the longitudinal direction. The first counter-guide is therefore designed as a slotted sleeve.The gap in the sleeve forms a longitudinal slot in which the web can move in the longitudinal direction to enable the carriage to be moved longitudinally along the rail. Since the first counter-guide engages around the first guide rod, the pivotability between the carriage and the rail about the pivot axis is also realized. The pivot axis then runs coaxially to the guide rod. The gap in the web provided in the second longitudinal region means that the first counter-guide can move into the gap during pivoting, thereby enabling pivoting between the carriage and rail. Since the first counter-guide engages around the first guide rod by more than 180°, preferably by at least 270°, the first counter-guide is held captively on the first guide rod transverse 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 on the respective long side of the rail via a web and extends straight in the longitudinal direction. In contrast to the first guide rod, the second guide rod only extends in the first longitudinal region. The second counter-guide engages around the second guide rod by more than 180° and less than 360°, so that the second counter-guide also has a gap which extends continuously in the longitudinal direction and which is dimensioned such that the web penetrates into the gap when the carriage is moved longitudinally in the longitudinal direction and penetrates the gap transversely to the longitudinal direction. The second guide and the second counter-guide are therefore constructed almost identically to the first guide and the first counter-guide in the first longitudinal section.Since the second guide rod extends only in the first longitudinal area, the 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 released 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 penetrating the rail 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 merges openly into the opening. The opening is larger in the transverse direction than the slot. The carriage now has a securing 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 securing element, and the connecting web are now coordinated in such a way that when the carriage is pivoted about the pivot axis between the intermediate position and the assembly position, the securing element can be adjusted through the opening. And when the carriage is moved longitudinally between the intermediate position and the holding position, the connecting web is longitudinally adjustable in the slot, penetrating the slot and positioning the securing element on a side of the rail facing away from the carriage. The securing element guided in the slot creates an additional positive connection between the carriage and the rail and improves the support between the carriage and the rail. The positioning of the securing element here is synonymous with a positive hold transverse to the longitudinal direction between the carriage and the rail by means of the shear 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 plugged onto and removed from the first guide rod in the longitudinal direction when the locking element is moved out of the opening by pivoting the carriage about the pivot axis, so that the carriage can be mounted on and removed from the rail. This results in particularly simple mounting and dismounting of the carriage on the rail.

[0015] A configuration is advantageous in this case in which the first counter-guide has a constriction in the gap at a longitudinal end facing away from the first longitudinal region of the rail, for example in the form of a nose protruding in the circumferential direction of the counter-guide, with this constriction being smaller in this circumferential direction than a web section that delimits the gap between the rail and the first guide rod on a side facing away from the first longitudinal region. Alternatively, it can also be provided that a web section that delimits the gap on a side facing away from the first longitudinal region is larger in a circumferential direction in which the first counter-guide engages around the first guide rod than the gap of the first counter-guide.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. This creates a retaining device for the carriage on the rail in the assembled position, as the carriage cannot fall off the first guide rod on its own.

[0016] According to another embodiment, a locking contour can be formed on one of the rail and carriage, said locking contour having a plurality of locking steps adjacent in the longitudinal direction. On the other of the rail and carriage, a counter-locking contour complementary to the locking steps can be formed, said counter-locking contour having at least one locking lug that cooperates with the locking steps to maintain the relative position between the carriage and rail in the longitudinal direction. The locking contour with a plurality of locking steps adjacent in the longitudinal direction predetermines a plurality of positions in the longitudinal direction between the rail and carriage, in which positions the carriage is held on the rail. This configuration is particularly advantageous in conjunction with a mounting frame, since the different locking steps allow the respective holding device to be easily adapted to different wall thicknesses of an opening edge surrounding the mounting opening in order to secure the mounting frame thereto.

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

[0018] According to another embodiment, the carriage can have a pressing area which, in the holding position, projects vertically away from the rail. With the help of the pressing area, when the holding devices are used on a mounting frame, a stable support of the respective carriage via the pressing area on the opening edge can be achieved. An embodiment in which the pressing area is connected to the carriage via a spring area, which can in particular be designed to be elastic, is particularly advantageous. In conjunction with the locking mechanism described above, which has several locking steps in the longitudinal direction, the mounting frame can be secured to the respective opening edge by clamping the opening edge between the pressing areas of the holding devices and the mounting frame with respect to the longitudinal direction.At the same time, this ensures clean installation with the mounting frame fitting perfectly around the edge of the opening.

[0019] A mounting frame according to the invention, which is intended for mounting a recessed luminaire in a mounting opening in a ceiling or wall bordered by an opening edge, has a frame body which has a flange for contact with an outer side of the opening edge facing away from the mounting opening, and a plurality of holding devices of the type described above which are arranged on the frame body in a circumferential direction. The flange runs along the frame body in a circumferential direction surrounding a longitudinal center axis of the frame body. Preferably, the flange runs closed in the circumferential direction around the frame body. The respective rail can now be firmly 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 one another along the rails.The mounting frame can be inserted into the mounting opening when 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 correctly inserted into the mounting opening, the mounting frame rests with its flange on the outside of the opening edge and is secured to the opening edge when the slides are in their holding position and are supported on an inside of the opening edge facing the mounting opening. In the holding position, the cross-section of the mounting frame in the area of ​​the holding devices is in any case 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 supported positively on the opening edge with the help of the slides. The opening edge 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 formed 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-in connection. This allows the frame body and slide to be easily manufactured separately, for example, as cast parts 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 intended for installation in a mounting opening in a ceiling or wall surrounded by an opening edge.

[0023] For this purpose, the recessed luminaire is equipped with a mounting frame of the type described above. It also has a lamp holder which is directly or indirectly connected to the mounting frame. At least one lamp can be arranged on this lamp holder, which lamp holder can in particular have at least one light-emitting diode. With the help of the mounting frame, the recessed luminaire can be installed particularly easily in a mounting opening. In this case, it can be provided that a detachable connection is provided between the mounting frame and the lamp holder, which is designed such that the mounting frame can first be mounted in the mounting opening without the lamp holder or fastened to the edge of the opening. The lamp holder can then be fastened to the mounting frame already fixed to the edge of the opening.Such a detachable fastening can be realized, for example, by a latch or by a bayonet lock or by a screw thread.

[0024] According to an advantageous embodiment, the recessed luminaire can have a reflector that connects the mounting frame to the lamp carrier. In particular, the aforementioned releasable fastening between the lamp carrier and the mounting frame can be formed between the reflector and the mounting frame, so that the reflector can be releasably attached to the mounting frame. The lamp carrier, in turn, can be permanently or releasably attached to the reflector.

[0025] According to another advantageous embodiment, the recessed luminaire can have a heat sink, in particular with cooling fins, which is connected to the lamp carrier in a heat-transferring manner.

[0026] Further important features and advantages of the invention emerge from the subclaims, from the drawings and from the associated description of the figures based on the drawings.

[0027] It is understood that the features mentioned above and those to be explained below can be used not only in the respective combination specified, but also in other combinations or on their own, without departing from the scope of the invention defined by the claims. Components mentioned above and to be mentioned below of a higher-level unit, such as a device, apparatus, or arrangement, which are designated separately, may form separate parts or components of this unit or be integral areas or sections of this unit, even if this is shown differently in the drawings.

[0028] Preferred embodiments of the invention are illustrated in the drawings and are explained in more detail in the following description, wherein the same reference numerals refer to the same or similar or functionally identical components.

[0029] They show, schematically, Figure 1 shows an isometric view of a recessed luminaire with a mounting frame having a plurality of holding devices, Figure 2 shows a slightly isometric view of a holding device in a holding position, Figure 3 shows a slightly isometric view of the holding device in an intermediate position, Figure 4 shows a slightly isometric view of the holding device in a mounting position, Figure 5 shows an isometric sectional view of the recessed luminaire.

[0030] According to the Figures 1 and 5 A recessed luminaire 1 comprises a mounting frame 2, a lamp carrier 3 and at least one Figure 5indicated illuminant 4, which is arranged on the illuminant carrier 3. The illuminant 4 can comprise 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 illuminant carrier 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 illuminant carrier 3 or on the reflector 5 and which is connected to the illuminant 4 in a heat-transferring manner. The recessed luminaire 1 is designed for installation in a Figure 5recognizable mounting opening 8 is provided, which is formed in a ceiling 9 or wall 10 and is bordered 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 holding devices 12, which are arranged on the mounting frame 2 in a circumferential direction U of the mounting frame 2. The circumferential direction U of the mounting frame 2 runs around a longitudinal central axis L of the recessed luminaire 1 or of the mounting frame 2.

[0031] According to the Figures 1 to 5 The respective holding device 12 has a straight rail 13 which is configured to be straight and flat and defines a longitudinal direction X, a transverse direction Y and a height direction Z which are perpendicular to each other. In the assembled state, in which the holding devices 12 are attached to the mounting frame 2, the longitudinal directions X of the holding devices 12 extend according to the Figures 1 and 5 parallel to the longitudinal center axis L of the mounting frame 2.

[0032] The respective holding device 12 is also equipped with a carriage 14, which is arranged on the respective rail 13 and is adjustable in the longitudinal direction X. The respective rail 13 has a rail length extending in the longitudinal direction X, a rail width extending in the transverse direction Y, and a rail thickness extending in the vertical direction Z. In the elongated and flat rails 13, the rail thickness is smaller than the rail width, which in turn is smaller than the rail length.

[0033] The respective rail 13 has a guide 15 on each of its two longitudinal sides facing away from each other in the transverse direction Y, said guide running in the longitudinal direction X. The respective carriage 14 has two counter-guides 16 that are designed to be complementary to the guides 15. The counter-guides 16 are coupled to the guides 15 and interact with the guides 15 to enable guided longitudinal displacement 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.

[0034] The carriage 14 is arranged between a Figure 2 shown holding position HS, one in Figure 3 shown intermediate position ZS and one in Figure 4shown mounting position MS relative to the respective rail 13. For illustration purposes, Figure 1 In the three holding devices 12 shown, the slides 14 are shown in three different positions. Figure 1 The carriage 14 is adjusted to the mounting position MS in the holding device 12 facing the viewer. Figure 1 The carriage 14 is moved into the holding position HS by the holding device 12 arranged on the left. Figure 1 The slide 14 is moved to the intermediate position ZS by means of the holding device 12 arranged on the right. In the sectional view of the Figure 5 only two of three holding devices 12 are visible. Figure 5 In the holding device 12 arranged on the right and shown in section, the carriage 14 is in the holding position HS. Figure 5The carriage 14 is in the mounting position MS in the holding device 12 facing away from the viewer and partially concealed by the lamp carrier 3 or the heat sink 6.

[0035] Figure 4 does not show the carriage 14 fully pivoted into the assembly position MS, but a pivot position MS', which results from the transition from the intermediate position ZS into the assembly position MS and which can be used, for example, to mount the carriage 14 on the rail 13, which will be explained in more detail below. The carriage 14 fully pivoted into the assembly position MS is shown in Figure 1 at the front holding device 12 facing the viewer and in Figure 5 can be seen on the rear holding device 12 facing away from the viewer.

[0036] According to the Figures 1 to 5In the holding position HS, the carriage 14 is located in a first longitudinal region 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, however, the carriage 14 is located in a second longitudinal region 18 of the respective rail 13, facing away from the first longitudinal region 17. This second longitudinal region 18 faces away from the holding 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 region 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.

[0037] Furthermore, the holding devices 12 are configured such that the one or first guide 15a extends from the first longitudinal region 17 to the second longitudinal region 18, while the other or second guide 15b extends only in the first longitudinal region 17, i.e., is 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 over approximately half the length of the rail. The one or 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 other or 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.

[0038] The first guide 15a has a first guide rod 19, which is connected to the rail 13 on the respective longitudinal side 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.

[0039] 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 uninterruptedly or continuously, while the first web 20 is interrupted in the second longitudinal region 18, such that a gap 21 is formed in the second longitudinal region 18 between the first guide rod 19 and the rail 13. The first counter-guide 16a engages around the first guide rod 19 by more than 180° and less than 360°. As a result, the first counter-guide 16a has a first gap 22 in its circumferential direction V surrounding 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 in the longitudinal direction X continuously through the first counter-guide 16a and is dimensioned such that the first web 20 penetrates into the first gap 22 during the longitudinal displacement of the carriage 14 in the longitudinal direction X and penetrates the first gap 22 transversely to the longitudinal direction X. This penetration and penetration is shown in . Figure 2 recognizable.

[0040] The second guide 15b can have a second guide rod 23, which is connected to the rail 13 on the respective longitudinal side of the rail 13 via a second web 24 and which extends in the longitudinal direction X. In contrast to the first guide rod 19, the second guide rod 23 extends only in the first longitudinal region 17, i.e., only approximately over half the rail length. 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 less than 360°. Consequently, 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 which is dimensioned such that the second web 24 penetrates into the second gap 25 during the longitudinal displacement of the carriage 14 in the longitudinal direction X and penetrates the second gap 25 transversely to the longitudinal direction X.This penetration and penetrating is also in . Figure 2 recognizable.

[0041] 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. As a result, the carriage 14 is no longer held on the second guide 15b via the second counter-guide 16b, so that the carriage 14 can pivot about the pivot axis S relative to the rail 13. Figure 3 an axial gap 26 can be seen, which is established between the second guide 15b or the second guide rod 23 and the second counter-guide 16b when the carriage 14 reaches the intermediate position ZS.

[0042] In the embodiments shown here, the rail 13 has an opening 27 which penetrates the rail 13 in the transverse direction Y between the two guides 15 and is located in the second longitudinal region 18. The rail 13 is also equipped with a slot 28 which penetrates the rail 13 in the transverse direction Y between the guides 15 and extends in the longitudinal direction X and extends from the first longitudinal region 17 into the opening 27. The opening 27 is larger in the transverse direction Y than the slot 28. The carriage 14 has a securing 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 securing element 29 is larger in the transverse direction Y than the web 30. The transverse direction Y of the carriage 14 corresponds to the transverse direction Y of the carriage 13, at least in the holding position HS.Furthermore, the opening 27, the slot 28, the securing element 29 and the connecting web 30 are coordinated with one another in such a way that in the intermediate position ZS the securing element 29 can be adjusted by pivoting the carriage 14 through the opening 27 and that when the carriage 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 and in the process penetrates the slot 28 in the vertical direction Z and positions the securing element 29 on a side of the rail 13 facing away from the carriage 14. Accordingly, the carriage 13 is in the holding position HS according to . Figure 2 arranged between the carriage 14 and the securing element 29.

[0043] 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 plugged onto the first guide rod 19 in the longitudinal direction X and removed therefrom when the securing element 29 is moved out of the opening 27 by pivoting the carriage 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 carriage 14 can be mounted on the rail 13 and removed therefrom. For example, the carriage 14 can be Figure 4 shown pivot position MS', which is between the intermediate position ZS and the one shown in the Figures 1 and 5 shown mounting position MS, pull it off the rail 13.

[0044] The first counter-guide 16a can have a constriction (not visible here) in the first gap 22 at a longitudinal end facing away from the first longitudinal region 17, which is smaller in dimension than a web section 20' of the first web 20, which delimits the gap 21 on a side facing away from the first longitudinal region 17. Alternatively, this web section 20' of the first web 20, which delimits the gap 21 on the side facing away from the first longitudinal region 17, can be larger in dimension than the first gap 22 of the first counter-guide 16a. In this way, a loss-prevention device is formed between the carriage 14 and the rail 13.

[0045] According to the Figures 1 and 5a locking contour 31 can be formed on the rail 13, which has a plurality of locking steps 32 adjacent in the longitudinal direction X. Complementary to this, the carriage 14 has a counter-locking contour 33, which has at least one locking lug 34, which cooperates with the locking steps 32 to maintain a relative position between the carriage 14 and the rail 13 with respect to the longitudinal direction X. The locking contour 31 and the locking steps 32 are located on a side of the rail 13 that faces the carriage 14 in the holding position HS. The locking steps 32 extend on both sides of the slot 28. The counter-locking contour 33 and the respective locking lug 34 are located on a side of the carriage 14 that faces the rail 13 in the holding position HS. They are thus located on the same side as the securing element 29 and face the securing element 29.

[0046] According to the Figures 1 to 5The slide 14 has a pressing area 35 which, in the holding position HS, projects away from the rail 13 in the vertical direction Z. The slide 14 also expediently has a preferably elastic spring area 36, ​​via which the pressing area 35 is connected to the slide 14. In the examples shown, the slide 14 is stiffened by means of lateral cheeks 43.

[0047] According to the Figures 1 and 5the mounting frame 2 has a frame body 37 which has a flange 38 which is configured such that the frame body 37 can come into contact via the flange 38 with an outer side 39 of the opening edge 11 facing away from the mounting opening 8. A plurality of holding devices 12 are arranged on the frame body 37 in a manner distributed in the circumferential direction U. In the examples shown, exactly three holding devices 12 are arranged on the frame body 37. It is clear that, depending on the geometry of the mounting frame 2, two or four or more holding devices 12 can also be used. The flange 38 runs around the longitudinal central axis L in the circumferential direction U along the frame body 37 and in doing so forms an edge which projects radially with respect to the longitudinal central axis L. The holding devices 12 are arranged on the frame body 37 such that their longitudinal direction X each extends parallel to the longitudinal central axis L.

[0048] 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 interfering contour that hinders the insertion of the mounting frame 2 into the mounting opening 8. When the mounting frame 2 is inserted into the mounting opening 8, the slides 14 are moved past the opening edge 11, are located within the mounting opening 8 and can be pivoted into the intermediate position ZS and subsequently moved into the holding position HS. The mounting frame 2, properly inserted into the mounting opening 8, then rests with the flange 28 on the outer side 39 of the opening edge 11 and is fixed to the opening edge 11 as soon as the slides 14 assume their holding position HS and are supported on an inner side 40 of the opening edge 11 facing the mounting opening 8. According to Figure 5the opening edge 11 is then clamped parallel to the longitudinal center axis L between the flange 38 and the respective slide 14.

[0049] The carriages 13 can form separate components with respect to the frame body 37 and can be fastened to the frame body 37, for example, by means of a locking connection 41. The locking connection 41 here has two locking arms formed on the rail 13, which are spring-elastic in the height direction Z and have locking lugs, and matching locking openings formed on the frame body 37. The frame body 37 runs in a closed manner 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 feasible, namely, in particular, other round, polygonal, or rectangular cross-sections.

[0050] For the installation of the recessed luminaire 1, it may be expedient 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 be formed, for example, between the mounting frame 2 and the reflector 5. The detachable connection 42 can be, for example, a snap-in connection or a bayonet lock.
