Running along each of two opposite sides (5, 6) of the rail is a T-shaped groove (7) used for mounting lights (8), attachments (8'), etc., while one (2') of the other two sides has a longitudinal slot (3) in which a cover strip (4) can be removably inserted.

Description

The invention relates to a mounting rail for lights, according to the introductory part of claim 1. Such a mounting rail is shown in CH 434 406 A.

It is known to mount lights on a hollow profile, which inside is the one for electrical connection contains the necessary electrical cables, cf. in addition to the aforementioned CH 434 406 A also e.g. DE 19 12 906 A. The carrier rail known from DE 19 12 906 A is spring-loaded Support bracket that protrudes from the actual profile Flanges work together, attached to a ceiling; the lights are connected with the help of separate adapters the profile, which is open at the bottom, and with connecting parts protrude into the profile. This construction is relatively complex.

Furthermore, there have already been mounting rails for luminaires for low-voltage lighting systems suggested that for example mounted in a horizontal position for illuminating showrooms and can be used directly to carry current, in particular a 12 volt voltage serves as supply voltage. The known busbars exist, cf. for example the DE 39 19 201 A, as a rule from two arranged side by side in parallel Profile bars that are insulated from each other and a total of a support and busbar with a rectangular cross-section surrender. For attaching lights to these rails serves a bow-shaped adapter, for example in cross section Is U-shaped and on the composite support or Busbar is pushed from the side. With such Lighting systems is not just a risk of a short circuit given the two bars of the support or busbar, but also disadvantageous that these known systems not suitable for supply with conventional mains voltage. On the other hand, the rectangular cross section is horizontal Arrangement of the mounting rails useful as far as then precise horizontal / vertical alignment is facilitated.

It is now an object of the invention to provide a mounting rail provided type to provide with the simple mechanical and electrical connections from mounting rails at the front Face and a clear alignment of suspension or. Support elements and lights on the mounting rail at the Assembly, a simplified assembly of the mounting rail on the suspension or supporting elements as well as lights and other Lighting system components on the mounting rail, one Supply with mains voltage, using separate electrical lines, is made possible, further electrical installation work simple on the mounting rail, etc. also in already installed state of the mounting rail, can be carried out should.

This object is achieved with a mounting rail as in claim 1 defined solved.

Support rails designed according to the invention are advantageous Assign each face to face by a kind Plug-in system both electrically and mechanically with one another detachable. In addition to achieving the plug connection option is also a fixation of the cover strip with the help of the respective connecting part on the front of the Profiles achieved.

The two long sides of the profile, on which the undercut, preferably T-shaped mounting longitudinal grooves provided are in the assembled, preferably horizontal state the mounting rail, the top or bottom of the profile, and the - preferably continuous - having the longitudinal slot Long side of the profile is on the side of this, so that via this longitudinal slot in a convenient way from the side Access to the profile interior for the purpose of laying and connecting the electrical cables etc., etc. also in the already assembled Condition of the mounting rail, is made possible. After completing this Electrical installation work inside the mounting rail is the Cover strip simply inserted and releasably attached, it this is of particular advantage if the cover strip by means of a snap connection connected or connectable to the profile is.

Overall, the present mounting rail fulfills on the one hand due to the generally rectangular, especially square, exterior Profile advantageously the required supporting function in mechanical terms, and in the interior can - in himself conventionally - housed the electrical wiring which are also there where there are lights on the mounting rail can be attached or hung using the longitudinal mounting grooves, through holes in the profile at these points can be. In addition, it is also conceivable that present mounting rail with low-voltage power rails, too combine; in other words, there can be such busbars on the present mounting rail, for example rod-shaped support elements (via which the power supply is also closed) the busbars can be made) and attached to them Low-voltage tracks will then become the low-voltage lights appropriate.

It should be mentioned that conductors or cable channels in the form of Hollow profiles with removable ceiling are already widely known have become, cf. e.g. EP 113 981 A, EP 149 377 A, EP 232 212 A, EP 239 945 A, EP 391 713 A, EP 518 404 A, EP 624 940 A, but also GB 1 398 848, GB 1 410 423, DE 21 09 614 A and DE 38 17 440 A. However, these facilities are primarily intended for the laying of electrical lines, where appropriate, connection devices in the form of sockets or the like. Are given, but in particular in openings the lid must be attached. For the suspension of Lights, e.g. below ceilings, these are well known However, rails or cable ducts are not provided.

For the snap connection between cover strip already mentioned and longitudinal slot of the profile can be inventive Support rail provided per se that in discrete places at intervals from each other along the cover strip or Slot edges of matching recesses and locking projections be attached, or that simply on the cover strip hook-shaped locking projections are provided which cover the edges simply reach behind the respective longitudinal slot. With regard on the fact that for the present mounting rail or the one forming it Profile preferred production by extrusion However, it is particularly favorable if the snap connection by along the longitudinal edges of the cover strip or Longitudinal slot continuously extending grooves or projections is formed. In this case, the cover strip can also be used Move longitudinally to close the respective longitudinal slot the profile is pushed on or to expose the longitudinal slot be pushed off the profile.

In connection with the fixation of the cover strip it has also proved to be particularly favorable if the cover strip on at least one end face one with an end face circular opening and optionally with a Side slot provided for a fastening screw has, which is characterized by a on the end faces of the Profile and the cover strip of the flange of the (respective) Connecting part extends. Furthermore, it is also from Advantage if the profile on the opposite of the cover strip Long side with a front, generally circular Opening and optionally a side slot Recording for a fastening screw is provided. Accordingly, you can continue to look for the actual profile as well extruded profile sections used for the cover strip be where the receptacles for the mounting screws through strip-shaped continuous projections on the extruded profile are formed.

In order for an already installed lighting system in which several mounting rails are coupled together, one shift of supporting or assembly parts or lights in the undercut Mounting longitudinal grooves over the joints between It is then also possible to enable the mounting rails favorable if the flange of the connecting part in the area of Longitudinal grooves of the profile has rectangular recesses, whose dimensions are adapted to the dimensions of the longitudinal grooves.

It has also become an additional position fix proven to be advantageous if on the flange of the connecting part projections directed towards the profile in the area of the longitudinal grooves are formed, which on the walls of the longitudinal grooves laterally issue. It is also an advantage in this context if in the corner areas of the flange of the connecting part Cylindrical projections formed towards the profile which are in with corresponding, generally circular, frontal openings and possibly with a side Slotted receptacles in the corner areas of the profile are insertable.

For safety reasons as well as unwanted soiling to avoid, it is also beneficial if at least one end of the hollow profile in its interior final, generally plate-shaped end part detachable attached or attachable. Such a closing part in Form of a simple, smooth outside plate is appropriate a free end of a mounting rail of a lighting system appropriate. For the attachment, the already mentioned, preferably provided screw receptacles on the profile or on the Cover molding can be used, and so is it of advantage if screws for fastening the end part are provided, which are through holes in marginal or Flange parts of the end parts and extend into the front Recordings on the inside of the cover strip and on the opposite long side of the profile are screwed.

Such a, generally simple, plate-shaped Concluding part is conveniently at all free ends of a Lighting system used with the present mounting rails, so an appealing, functional conclusion of the hollow To achieve profiles. However, these end parts can also be designed such that an articulated connection between the mounting rails, and it is therefore particularly advantageous if the end part has a Joint is connected to another end part. It is it is conceivable that a universal joint or ball joint is provided, so that all-round swiveling guaranteed. However, this can result in the implementation problems with the electrical cables. With regard the one specified by the rectangular cross-sectional configuration Alignment and horizontal mounting of the mounting rails is usually a swivel by one in the assembled state vertical pivot axis is sufficient, and accordingly it is in Further development of the last-mentioned embodiment in particular advantageous if the joint is a swivel joint, the Swivel axis in a passing through the longitudinal grooves Plane of symmetry of the profile. It can easily be a Training will be taken in the middle of the space for the implementation free from electrical cables. Preferably is further provided here that the swivel joint by each two fork-shaped from the respective end part in the longitudinal direction of the profile protruding articulated arms is formed, with a Articulated bolts through a pair of articulated arms belonging together extends.

To then by a stop or mutual investment exact right-angled alignments of such articulated with each other It is also possible to enable coupled mounting rails favorable if each end part on its to the pivot axis parallel edge edges facing away from the profile 45 ° bevel, the. defined 45 ° plane runs through the pivot axis.

For the implementation of a flexible electrical connection cable Finally, each connector can simply be one central, e.g. have a circular opening.

In Figures 1 to 4 and 7, 1 generally designates one Carrier rail in a training as at least as currently is considered particularly cheap and preferable, and that a has a hollow profile 2, the one in a longitudinal side 2 ' has continuous longitudinal slot 3, which in the assembled state is filled by a flush cover strip 4, so that the support rail 1, seen in cross section, a closed rectangular, in particular square, outer contour having.

The profile 2 is on its top 5 and on its Bottom 6 ("top" and "bottom" refers to the position in the assembled state) each with an undercut, e.g. dovetail-shaped or T-shaped mounting longitudinal groove 7, which for accommodating one, the dimensions of the longitudinal groove 7 adapted square nut 7 ', which is used in the front respective longitudinal groove 7 can be inserted. In this square nut 7 'screws, threaded bolts or the like can be screwed in which, for their part, rod-shaped suspension or Support parts 8 or 8 'for fastening lights, spotlights, Busbars, power supply devices, in particular ballasts, or rods, ropes, chains, donations, etc. on one any place of the mounting rail 1 are provided.

The cover strip 4 is in the illustrated embodiment connected to the profile 2 via a snap connection 9, provided in the area of the longitudinal edges of the cover strip 4 is. For this purpose, the cover strip 4 has on its longitudinal edges inward longitudinal ribs 10 on her free end are thickened, making one each Shallow depression or groove 11 extending in the longitudinal direction is formed, in which rounded, in the longitudinal direction extending projections 12 of the profile 2 at the edge of the longitudinal slot 3 can be locked, the profile 2 when pressed the cover strip 4 in the longitudinal slot 3 widened resiliently until the projections 12 snap into the grooves 11.

Instead of the continuous projections 12 or locking grooves 11 could also be discrete locking projections or recesses be provided at spaced locations, however the continuous training with regard to the desired Production of the mounting rail 1 and the cover strip 4 as Extruded profiles preferred.

Around multiple mounting rails 1 in a simple and quick way To be able to line up in length is in profile 2 at least one end has an electrical and mechanical one Connecting part 13 inserted, which from a profile 2 flat final plate part or flange 14 and one this molded multi-pin connector part 15 is made. This connector part 15 is in the present example for nine electrical connectors designed in three rows and three columns of bores 16 are arranged in insulating sleeves 16 ' are to nine sockets (not shown) that with electrical connection lines (schematically at 16 "in FIG. 1) shown) are connected to record. For mechanical Connection of the connecting part 13 with the profile 2 and with the Cover strip 4 are the profile 2 and the cover strip 4 on their End faces each with receptacles 17 and 17 'for screwing in provided by screws 18, the head of which is each in a graduated Bore or counterbore 19 is held in the flange 14. The receptacles 17 and 17 'are through corresponding profile areas as mentioned above, preferably by extrusion Obtained mounting rail profile 2 formed and have, as from 4 is recognizable, an approximately circular face Opening and a side slit. For additional mechanical position securing of the connecting part 13 on the profile 2 are on the top and bottom of the connector part 15 two projections 20 extending from the flange 14, e.g. in the form of Noses, molded, their free distance from each other the distance corresponds to the outer side walls of the mounting longitudinal grooves 7; in the assembled state, these nose projections 20 are Position fixation on the side of the walls of the longitudinal grooves 7 on the outside.

The electrical and mechanical connection between two Carrier rails 1 are then carried out in detail with the aid of a separate, plug-like intermediate part 21, which in Fig.5 and 6, and in which, complementary to the socket part 15, nine pins 22 in three rows and three Columns are used in an insulating part 23, the Plug pins 22 freely in stepped bores 24 on both sides protrude with when plugging the intermediate part 21 with the connecting parts 13 of two mounting rails 1 to be connected enclose the insulating sleeves 16 'of the socket parts 15, while the connector pins 22 into the sockets of the socket elements 15 intervene.

The outer contour 25 of the intermediate part 21 is, as from the Figures 2 and 6 can be seen, the inner contour 26 of the Insulating sleeves 16 'surrounding cavity 27 of the connecting part 13 adjusted with little play, so that when inserting the Intermediate part 21 in the respective connecting part 13 or in the socket part 15 in addition to the electrical coupling a mechanical connection between these parts 13, 21 will be produced.

So that the connector pins 22 of the intermediate part 21 only with correct polarity in the sockets of the respective connector parts 15 can be inserted, is the inner contour of the cavity 27 of the connecting part 13, from the front side the flange 14 seen here, only simply symmetrical, s. in particular Fig.2, so that the intermediate part 21 with its complementary outer contour only in one predetermined location, that of proper electrical connection between the connector pins 22 and the connector sockets, insertable into the respective socket part 15 is. For this purpose, for example, is the top side surface of the intermediate part 21 or of the cavity 27 is made flat, see. Fig.2 and 6, while the other side faces one have a shape composed of cylindrical subsegments, the inner wall of the cavity 27 complementary to this Education is shaped.

As shown in Fig.4, the one with dash-dotted lines Line outer contour of the socket part 15 a similar shape to the outer contour within the profile 2 of the intermediate part 21, the top and bottom of the Socket part 15 directly on the wall of profile 2 rest in the area of the T-shaped longitudinal grooves 7, whereby a additionally improved mechanical hold of the connector part 15 within the profile 2 is given.

The flange 14 of the connecting part 13 is on his Corners with cylindrical projections directed towards profile 2 28 provided; these projections 28 are when inserting the connecting part 13 in the front of the profile 2 in matching Openings 29 can be inserted in the corners of the profile 2, so that a further mechanical connection between the connecting part 13 and the profile 2 is created.

Are also on the flange 14 in the area of the T-shaped Longitudinal grooves 7 of the profile 2 opposite one another rectangular Recesses 30 provided the width and depth of the T-shaped longitudinal grooves 7 correspond; these recesses 30 allow insertion of the square nuts mentioned inserted connecting part 13 and moving within the T-shaped longitudinal grooves 7 from a mounting rail 1 to one neighboring mounting rail in the assembled state over the Recesses 30 away.

The connecting parts 13 and the intermediate parts 21 are made e.g. made of plastic, while the profile 2 and the cover strip 4 optionally made of light metal, e.g. Aluminum, anodized and dyed, or brass (chrome-plated) or fiber-reinforced Plastic can exist.

In Figures 8 and 9 is a plan view and a view schematically a hinge connection 31 of two per se identically designed support rails 1 (see Fig.1 to 4) illustrates; the joint 32 provided is a swivel joint with a pivot axis 33 which in a through the Mounting longitudinal grooves 7 going vertical plane of symmetry 34 runs; this allows a mounting rail 1 relative to others pivoted horizontally in both directions by 90 ° are, as indicated schematically in Fig. 8, see. the drawn arrow 33 '.

In detail, the profiles 2 of the two mounting rails 1 on their faces by generally plate-shaped end pieces 35 completed here to form the articulation 31 in each case two flat, protruding in the longitudinal direction have plate-shaped articulated arms 36, 36 'and 37, 37'.

In the present example, the end parts 35 with the Articulated arms 36, 36 'and 37, 37' in one piece made of metal, e.g. Aluminum, manufactured, especially cast. The attachment of the end parts 35 on the end faces of the profiles 2 further preferably in the same way as the attachment of the Connecting parts 13, namely via those already explained Recordings 17, 17 ', in the corresponding blind holes (see the holes 19 in Fig.1) in two opposite Edge parts or flange areas of the end parts 35 inserted through them Screws (corresponding to screws 18, see Fig. 3) be screwed in; also can have nose projections similar to the explained nose projections 20 and / or cylindrical corner projections corresponding to the projections explained 28 may be provided. In connection with these mounting options is for simplicity to the above Explanation and illustration of Figures 1 to 4 referenced.

The articulated arms 36, 37 and 36 '37' are in the assembled Condition in pairs on each other, as shown in Fig. 9 in particular can be seen, with holes in the hinge pin 38th are screwed in, aligned with each other so that the vertical Pivot axis 33 is thereby determined.

In itself, even if there is no connection of mounting rails 1 is required, the profiles 2 through such plate-shaped end pieces completed without articulated arms become.

In the plates of the end parts 35 are - in the case of Formation of an articulated connection 31 - furthermore openings 39 in the middle provided the implementation of flexible electrical Connection lines 40, in particular multi-core sheathed cables (see Fig.9), allow to make the electrical connection between the hinged rails 1 to provide.

From Fig. 8 it can also be seen that the two are mounted State of vertical edge 41 of each end part 35, facing each other, beveled at 45 °, whereby the 45 ° planes 42 thus defined by the vertical pivot axis 33 run. In this way, an exact system of the Edge edges 41 and thus an exact 90 ° orientation of the coupled Carrier rails 1 ensured in their end pivot position, see. the dash-dotted rail 1 'shown in Fig.8.
