In the shown example 4 facing the light exit opening downwardly, so that the direction R here facing vertically downwards, with respect to the fitting opening to a space so 1 side. In particular can therefore be provided, with the aid of a light output by the light exit opening that holding device 4 into the lower half-space is effected or for space side.

[0030] Further comprises a holding member for holding the mounting rail 3 the holding device 5 in the installation opening 1.

[0031] The holding device further comprises a gripping element 6, wherein the shaping is such, that by a movement of the engagement element relative to the mounting rail 3 5 6 the holding element from a mounting position by rotation and a subsequent - - translates in the direction R into a holding position for holding the mounting rail 3 in the installation opening 1 is offset.

[0032] In the shown example is the design in such a way, that the supporting rail 3 with said holding member 5 from the room side 1 can be introduced into the installation opening, when the retaining element 5 in the mounting position. The holding element 2 is in the position shown in the figfig. 5. When the support rail 3 as provided in the installation opening and the retaining member is in the holding position 5 is 1, 5 held by the holding element 3 is the supporting rail, in particular, in that the holding element 5 from above the ceiling 2 rests on surface areas, for example on the upwardly facing surface areas 22 of the ceiling elements 21. 1 Is the holding element in the holding position 5 in the figfig. outlined, but without the ceiling 2 here.

[0033] Generally can be provided, in that the holding device has at least two holding elements, with respect to the longitudinal axis extending at different longitudinal positions on the mounting rail 3 are, wherein the shaping of them and their connections to the carrier rail 3 analogous to the shape of the holding member 5 is described here. This description is therefore limited to only such a holding element. If at least two holding elements are provided corresponding, in the mounted position of the retaining elements are each must accordingly, if the mounting rail 3 in the installation opening from the room side be introduced into 1.

[0034] The carrier rail 3 may in particular be designed as a profiled part, a U-shaped cross section in a first approximation, so that a first U-leg 32, a second U-leg 33 and a, the two U-legs 32, 33 are formed mutually connects connecting leg 34. The light exit opening is governed by the free end portions of the two U-legs 4 32, 33 limited. Between the two U-legs 32, 33 is a supporting rail lnnenraum 35 formed, for example for receiving a lamp is provided.

[0035] At the two end portions of the U-legs 32 are preferably free, 33 - with respect to the U-shape - outwardly facing flanges 31 formed, for example molded, are designed to reduce the, when installing the mounting rail 3 in the installation opening from below against the ceiling 1 2 be brought into abutment, for example against the downwardly facing surface portions 23 of the ceiling elements 21.

[0036] The configuration is preferably such accordingly, viewed in direction R 3 - that the carrier rail, as "from above", the holding element 5 on both longitudinal sides not beyond flanges 31, when the holding member 5 in the mounting position. For example the design can be such, that ranged between the outer edges of the flanges 31 and the holding member 5 is formed respectively on both sides a distance d, between 5% and 40% of the, preferably 10% and 30% of the width b of the carrier rail 3 at the free end portions of the two U-legs 32, 33, the flanges 31 without, is.

[0037] As in the shown example the case, can be provided particularly advantageous, that the two U-legs 32, 33 for example by a step 39 taper upwardly, so that the retaining element 5 in the mounting position in the direction R seen completely within the two free end regions of the two U-legs 32, 33 is.

The rotation of the screw 6 by friction between the screw and the retaining element 5 will 6 5 transmitted to the supporting member. In this embodiment the rotation of the holding member 5 thus takes place about an axis of rotation, the screw coincides with the longitudinal axis 6.

[0041] As exemplary in figfig. 1 outlined, the holding element 5 preferably has a base portion 12 and two, 12 foot portions extending from said base from 13 on, with respect to the support rail extending on two opposite sides 3, 4 when the holding element is in said gripping position. The base portion 12 is preferably at least in first approximation configured and preferably extend the two foot portions 13 plate from said base portion 12 in the direction R or downwardly. In Figures 7 and 8 are two perspective sketches of the holding element 5 in the form of separated from the mounting rail 3 outlined.

[0042] At least one of the foot portions 13 preferably has a particular edge shaped edge region 131 on, wherein the configuration is preferably such, rotation of the holding member 5 is limited by that said, 131 that the edge area supported against a outside of the U-legs 32, 33 passes.

[0043] After rotation of the holding member 5 by further rotation of the screw 6 can be in translation in the direction R enable the holding element 5, so that in the installed state - - the root sections from above against the ceiling 13 finally reach 2. In this state the holding element 5 in the holding position. The rail 3 is in the holding position by the holding element 5 held within the installation opening arranged 1. In particular can be provided, that the sheet 2 or the ceiling elements 21 by the foot portions 13 on the one hand and on the other hand the flanges 31 of the holding member 5 are clamped in the holding position, so that secure positioning of the carrier element 3 is effected.

[0044] Is preferably in the direction R as seen from above the holding element 5 or trapezoidal shaped. The holding member 5 is separated from the support rail 4 into figfig. 3 viewed in direction R outlined, wherein the longitudinal axis L is indicated by an arrow here in addition. One can see the trapezoidal form of the support 5, the at least substantially by the shape of the base portion 12 formed here is. 4 Shows the holding element in the mounted position 5 this figfig.. 5 Is a corresponding sketch shown in the figfig., after rotation and translation in the holding position the holding element 5 shows. In Figures 4 and 5 is further detected the origins of the foot portions 13 and the corresponding edge regions 131. 6 Shows a the corresponding sketch figfig. figfig. 5, but with a surrounding region of the support rail by the rotational movement of the holding member 5 is 3rd three arrows from the mounting position indicated. In the figfig. 6 is further recognizable, 131 that the edge area of the foot portions of the two U-legs 13 against an outer surface 32, 33 bears, whereby a further rotation of the retaining member 5 is prevented. It is further recognized, that in the holding position the two foot portions 13 of the holding member 5 laterally over the two flanges extend beyond 31, so that a suitable abutment against the ceiling 2 is permitted.

[0045] Preferably are the two foot portions 13 of the holding member 5 plate-like and each for example via a bending edge 121 connected with said base portion 12. Here are the two foot portions 13 in the mounting position of the holding element 5 space saving advantageously parallel to the two U-legs 32, 33 aligned, especially in abutment against the outer sides of the two U-legs 32, 33. If, as in the shown example the case, the two foot portions 13 are formed symmetrically to each other, so that two edge regions are formed corresponding 131, 131 - 4 - indicated as in the edge regions must figfig. along the longitudinal axis L a longitudinal spacing a be seen spaced apart, so that rotation of the retaining member from the mounting position to allow 5 out. Said trapezoidal shape of the holding element is therefore 5 with respect to a space-saving execution advantageous overall.

[0046] It is particularly advantageous, if it is roughly the same as the longitudinal spacing a of this rectangular transverse spacing a of the two foot portions 13, since in this case a rotation of the holding member 5 is suitable width allows. For example can be provided, that the longitudinal distance a and the transverse distance A is less than 15% different from each other. For example the design can be such, that the rotation of the holding member for an angle of 90° ± 10° 5 results.

[0047] Preferably the holding device further comprises a spring element 7, for example in the form of a compression spring on, the one hand between the support rail and said support member is operatively arranged on 3 5. By the spring element 7 is the holding element 5 with respect to the mounting rail 3 against the direction R or urged upwards, so that during rotation of the screw the screw head with respect to the mounting rail 3 6 9 is maintained at a level. By the movement of the engagement element, the rotation of the screw 6 wherein translational movement of the retaining element here is the spring element 7 5 increasingly tensioned. By the spring element 7 can be guided movement of the retaining member relative to the mounting rail 3 causing a particularly 5.
