Description

The invention relates to a system for realizing a luminaire elongated in a longitudinal direction according to the preamble of claim 1 and a luminaire realized by means of the system. The invention also relates to a plug-in device according to claim 12 and a method according to claim 13.

Generic systems are used to produce elongated lights, which are commonly referred to as light strips. Such generic elongated lights or light strips form a separate class of lights that are used in a wide range of applications, for example in warehouses, production halls or supermarkets. These luminaires have a modular structure so that these luminaires can be used in a correspondingly wide range of applications. In addition, the lights are designed in such a way that they can be easily installed in any length at the place of use. For this purpose, the basic structure of such luminaires is formed by support rails that are elongated in a longitudinal direction, each of which has a cross section perpendicular to the longitudinal direction, which is open at one end along a vertical direction and at least partially closed at the opposite end, and which is at least partially closed along a transverse direction by two side walls is limited. The vertical direction and the transverse direction are perpendicular to one another and each perpendicular to the longitudinal direction. The mounting rails are Usually attached to a room ceiling in such a way that the open end of the cross-section of the mounting rails points away from the ceiling towards the room, so that lighting means can be provided in the mounting rails, which emit light into the room through the open end of the cross-section of the mounting rails. The support rails often have a cross-section in the manner of a U-shape with a U-bottom and U-side walls, the bottom being opposite the open end of the cross-section and the mounting rails being fastened via the U-bottom. To implement the elongated lights or light strips, the support rails are arranged next to one another in the longitudinal direction and connected to one another via a connector, so that the support rails are fixed in their relative position to one another by the connector. In each support rail, a power guide rail is provided which, depending on the embodiment, can also be configured in several parts, with plug-in devices being provided at the longitudinal ends of the power guide rail and lead wires being guided in the power guide rails. A conductor rail is thus suitable for guiding conductor wires along the longitudinal direction through the carrier rail assigned to it and insulated from one another and to the carrier rail. The power guide rails of adjacent mounting rails can be electrically connected to one another in a simple manner via the plug-in devices by plugging them into one another, and lighting means can be supplied to the conductor wires by suitable power tapping means, which are well known in the prior art. In most cases, the mounting rails in the luminaires are closed by a cover at the open end of their cross-section.

A generic system is used to implement the generic elongated luminaires described. A generic system comprises a plurality of support rails designed to be elongated in the longitudinal direction, and a plurality of support rails designed to be elongated in the longitudinal direction Conductor rails, several plug-in devices and at least one connector. To implement a generic luminaire explained, the various elements of the system are arranged in an operating position with respect to one another. The operating position thus describes the relative arrangement of the components of the system, which is necessary for the realization of a lamp. In the operating position, a first and a second support rail are arranged next to one another in the longitudinal direction. In addition, in the operating position, a first conductor rail is arranged within the cross section of the first support rail and a second conductor rail is arranged within the cross section of the second support rail. As explained in relation to the generic lights, a conductor rail, which can optionally be configured in several parts, is received by a support rail in the operating position. In addition, the connector is arranged on the support rails in the operating position, in particular within the cross section of both support rails, the connector connecting the two support rails to one another in the operating position. The connector can be implemented, for example, by means of metal strips which are fixed within the cross section of both support rails on the two adjacent support rails in a conventional manner, for example by means of snap-in connections, screw connections or bayonet connections. The connector can also be designed, for example, as an elongated element with eccentric clamping connections on two spaced apart longitudinal sections, via which the connector can be clamped to the support rails and the support rails can be fixed to one another accordingly. In one embodiment, the connector is designed as an elongated component which has a cross-section in the manner of a U-shape, which in the operating position is arranged in longitudinal guides formed by the support rails and is clamped to the support rails to fix the relative position of the two support rails to each other. In one embodiment, the connector is a component that is completely separate from the mounting rails; in one embodiment, the connector is partially formed by a first component separate from the mounting rails, partially by a second component formed by at least one of the adjacent mounting rails, these components then having the function together of the connector. In addition, in the operating position a first plug-in device is connected to the first conductor rail and a second plug device corresponding to the first is connected to the second conductor rail, and in the operating position the plug-in devices are plugged into one another, so that the conductor rails of the adjacent mounting rails are electrically connected to one another by the corresponding plug-in devices are. For example, one of the plug devices can be designed as a plug and the corresponding plug device as a socket. In general, the mounting rails are particularly preferably made from sheet metal, for example by means of a stamping and bending process. The at least one connector is generally preferably made from sheet metal, preferably by means of a stamping and bending process. In general, the conductor rails and / or plug devices are made of plastic, in particular by means of injection molding or extrusion processes, the conductor rails are preferably manufactured by means of extrusion processes and / or the plug devices are manufactured by injection molding. It is clear to a person skilled in the art that, in order to implement a lamp, several, almost any number of mounting rails with associated power guide rails and plug devices can be arranged next to one another in the longitudinal direction and mechanically connected to one another via a connector or electrically connected to one another via the corresponding plug devices.

The problem with generic systems has been the Realization of the plug-in connection between two corresponding plug-in devices of the conductor rails of adjacent support rails. The two corresponding plug-in devices are usually plugged into one another by being moved towards one another in the longitudinal direction. During this relative movement, the conductor rails, on which the corresponding plug-in devices are arranged and which have a considerable length in the longitudinal direction, are also to be moved towards one another as a whole. Often the conductor rail is first attached to the carrier rail assigned to it, after which the plug connection is created by moving the entire carrier rails in the longitudinal direction, including the conductor rails and the plug-in devices arranged thereon, towards one another. In any case, it is difficult and unwieldy for the fitter to bring the plug-in devices together. In addition, since the plug-in devices usually have a large number of isolated contacts, usually a number of at least eight plug-in contacts, preferably at least ten, in particular eleven plug-in contacts, the corresponding plug-in devices must also be guided very precisely to one another when they are plugged into one another, so that the corresponding plug-in ends the corresponding plug-in devices can interlock. Since the handling of elongated busbars without prior attachment to mounting rails is difficult because of the insufficient rigidity at the given length and because when the busbar is fixed to the mounting rail and the corresponding plug-in devices are subsequently plugged into one another, the entire units including the mounting rail, power control rail and plug-in device are precisely related to one another must be aligned, is for the fitter in generic systems, the implementation of an electrical connection between adjacent power rails plugging the corresponding plug-in devices into one another is always difficult. In DE 10 2012 007 086 A1 For example, a plug-in device for electrically coupling a conductor rail is disclosed, which has a plug-in body with electrical contacts, guide rails running in the longitudinal direction and lateral insulating pegs, the plug-in device being fixed via the guide rails and lateral insulating pegs to a lighting element comprising a support rail and a conductor rail can and thereby engage contacts of their plug-in body in the power conducting rail. EP 3 009 732 A1 discloses lighting elements which have electrical plug-in devices that correspond to one another at their longitudinal ends. DE 10 2012 202 148 A1 discloses a system with light strip elements, each comprising a support rail, a lighting means, electrical components and optics, wherein two light strip elements can be mechanically connected to one another via a connector and, in addition, an electrical connection of the light strip elements is made possible.

The present invention is based on the object of providing a system for realizing a luminaire which is elongated in a longitudinal direction, by means of which the above-described problems that occur in generic systems when realizing a luminaire can be at least partially eliminated.

As a solution to the described object on which the present invention is based, the invention proposes a system having the features of claim 1. The system comprises several longitudinally elongated support rails, several longitudinally elongated power conducting rails, several plug-in devices and at least one connector. The mounting rails each have one a transverse direction is limited by two side walls. In an operating position, a first and a second of the support rails are arranged side by side in the longitudinal direction, a first of the power guide rails is arranged within the cross section of the first support rail and a second of the power guide rails is arranged within the cross section of the second support rail, the connector is arranged on the support rails, connects the Connecting the two support rails to one another, a first of the plug-in devices is connected to the first power supply rail and a second, corresponding to the first of the plug-in devices is connected to the second power supply rail, and the plug-in devices are plugged into one another. The system can have further features that are explained above in connection with generic systems or generic lights. Preferably the connector is in the operative position arranged within the cross section of the first and second support rails. According to the invention, the first plug-in device has a plug-in body, a retaining projection being provided on at least one side of the plug-in body that delimits the plug-in body perpendicular to the longitudinal direction. The side limits the plug body in a certain direction that is perpendicular to the longitudinal direction. The retaining projection is thus located outside of the plug-in body in relation to the section of the plug-in body which is delimited from the side, in relation to the specific direction along which the side delimits the plug-in body. The retaining projection has an axis via which it is connected to the plug-in body. The axis preferably runs along the specific direction, which runs in particular along the transverse direction. The holding projection also has two holding areas which, starting from the axis, extend along the longitudinal direction over at least 5 mm away from the axis. The holding areas are therefore located outside of the axis with respect to the longitudinal direction. Both holding areas are preferably connected to the plug-in body exclusively via the axis. The connector has a guide, the two holding areas of the holding projection being arranged in the guide in the operating position. Alternatively, the first support rail on the guide, or the guide can be formed jointly by the connector and the first support rail. The guide is preferably designed to be elongated, with both holding areas and the axis being arranged in the longitudinal extension area of the guide.

Thanks to the design of the first plug-in device, the system according to the invention has particular advantages compared to conventional systems. By providing a plug-in body which has a holding projection which is connected to the plug-in body via an axis, as explained, and whose holding areas are in the guide of the connector or the first mounting rail, on the one hand a fixation of the first plug-in device relative to the connector is ensured, on the other hand, however, at the same time a flexible alignment of the plug-in body relative to the connector while maintaining the fixation of the plug-in body relative to the connector. Because thanks to the arrangement of the holding areas along the longitudinal direction outside the axis, the plug-in body can be pivoted about the axis while its holding areas are guided in the guide. When two corresponding plug-in devices are plugged into one another to implement a lamp with the aid of the system according to the invention, the first plug-in device can thus first be fixed to the connector by means of the holding areas, after which the second plug-in device can then be pushed in the longitudinal direction onto the first plug-in device and the connector thereby a Holding function fulfilled based on the first connector. A high-precision alignment of the second plug-in device relative to the first plug-in device is not required, since the first plug-in device can pivot relative to the connector when the first and second plug-in device meet, thanks to the mounting around the axis, which considerably simplifies the interconnection of the first and second plug-in device can. It has been found to be particularly advantageous to configure the holding areas in such a way that, at least in longitudinal sections, they have a greater vertical extent than the axis. This enables the plug-in body to be tilted relative to the connector during the arrangement of the holding areas in the guide in a particularly comprehensive manner. It has been found to be particularly advantageous to configure the holding areas in such a way that they each have their maximum vertical extension length over less than a third of their extension length in the longitudinal direction and / or over less than one third of their extension length in In the longitudinal direction have a vertical extension length which is at least 2 mm greater than the vertical extension length of the axis. This results in the smallest possible contact surface of the holding areas along the vertical direction on the guide or a sufficient vertical clearance, whereby tilting of the plug-in body relative to the connector can be further simplified. Furthermore, it has been found to be particularly advantageous to design the vertical extension length of the holding areas in each case slightly smaller than the vertical extension length of the guide, so that there is vertical play between the guide and the holding areas. For example, the vertical extension length of the holding areas can be between 0.5 mm and 2 mm less than the vertical extension length of the guide. The play can improve the variability of the alignment of the plug-in body relative to the connector even further. In one embodiment, however, for reasons of skill, no such vertical play is provided, so that the holding areas in the operating position bear vertically on the guide. The inventive system is always based on the inventive idea that the retaining projection has an axis within the extent of which the connection between the retaining projection and the plug-in body is realized, the holding areas extending away from the axis in the longitudinal direction, thereby increasing the flexibility of the alignment of the plug-in body is ensured relative to the connector, while the plug-in device is fixed relative to the connector via its retaining projection. In addition, the provision of run-in bevels at the end of the first plug-in device facing away from the first conductor rail has proven to be particularly advantageous. This end is designed as a plug end that is brought together with the corresponding plug end of the second plug device to establish an electrical connection between the Plug contacts of the two plug devices. The run-in bevels are bevels at the mentioned end of the first plug-in device, which guide the second plug-in device when the second plug-in device hits the said end of the first plug-in device to the position in which the contacts of the first and second plug-in device can interlock. The run-in bevels in combination with the rotatability of the plug-in body relative to the connector simplifies the insertion of the first and second plug-in devices into one another to a particularly high degree when realizing a lamp using the system according to the invention. The run-in bevels are particularly preferably provided in the extension region of the plug-in body. Inlet bevels are particularly preferably provided both on the named end of the first plug-in device and on the longitudinal end of the second plug-in device facing away from the second conductor rail. The holding areas are particularly preferably spaced apart from the plug-in body via the axis in the transverse direction. The axis direction particularly preferably runs parallel to the transverse direction.

In one embodiment, the holding areas each have two holding webs running along the longitudinal direction and spaced apart from one another along the vertical direction by a free space, which are connected to the axis at one of their longitudinal ends and are connected to one another at their opposite longitudinal end via a vertically running web. The inventors have recognized that a corresponding implementation of the holding areas ensures that the holding areas have, on the one hand, sufficient stability to fix the first plug-in device relative to the connector, but on the other hand, at the same time, compression of the holding areas along the vertical direction is made possible, at least in longitudinal sections, whereby a even more flexible alignment of the Plug-in body relative to the connector and thus an even simpler plugging into one another of the first and second plug-in device for realizing a lamp can be made possible.

In one embodiment, a projection is provided on each of the holding webs, which protrudes vertically away from the respective holding web. The projection is particularly preferably arranged on the side of the holding web which faces away vertically from the side of the holding web on which the vertically adjacent holding web is arranged. Particularly preferably, each of the projections takes up less than a third of the longitudinal extent of the holding area, preferably less than a fifth of the longitudinal extent of the holding area in which it is arranged. Correspondingly, the projections ensure that the holding areas have a greater vertical extent in a small longitudinal section area than in the adjacent longitudinal section areas. This can particularly preferably ensure that the holding areas in a longitudinal section area have a greater vertical extent than the axis. Particularly preferably, the projections provided in one of the holding areas are arranged vertically one above the other, so that a projection is arranged on each of the two holding webs which are vertically spaced from one another, the two projections which are arranged on the two holding webs arranged vertically one above the other and which are in the same holding area are arranged vertically one above the other. The projections are particularly preferably arranged in the middle third of the longitudinal extent of the respective holding area. The projections and their particularly preferred arrangement, as explained, increasingly ensure a simplification of the arbitrary alignment of the plug-in body relative to the connector, while the first plug-in device is fixed relative to the connector via its holding areas.

In one embodiment, the first plug-in device is guided relative to the connector along the transverse direction via a guide device. The guide device can be implemented, for example, via a groove provided on the connector and a spring provided on the first plug-in device or a spring provided on the connector and a groove provided on the first plug-in device. Particularly preferably, the guide device guides the first plug-in device relative to the connector along the transverse direction with a play between 0.5 mm and 2 mm, in particular between 0.5 mm and 1 mm. This can be achieved, for example, by appropriately designing the tongue and groove. Tongue and groove can be elongated, for example, in the longitudinal direction. In one embodiment, the guide device can comprise a guide section which is arranged on the first plug-in device and engages behind a corresponding guide section which is provided on the connector to determine the relative position of the first plug-in device relative to the connector with respect to the transverse direction. In one embodiment, a guide section is provided on at least one of the holding webs, preferably on a plurality of the holding webs, preferably on all holding webs, which extends vertically beyond the projections provided on the holding web and which is arranged offset in the transverse direction to the projections of the holding web . The guide section can, for example, engage behind a section of the connector by running parallel to the section of the connector along the vertical direction and along the longitudinal direction.

In one embodiment, a holding projection is provided on each of the two opposite sides of the plug-in body in the transverse direction, each of the holding projections having an axis over which it is connected to the plug-in body, and each of the holder projections has two holding areas which, starting from the respective axis, extend along the longitudinal direction over at least 5 mm away from the respective axis. The axes of the two holding projections are preferably aligned with respect to the transverse direction. As a result, tiltability of the plug-in body relative to the connector about both axes can be particularly favored. In the embodiment described, the connector preferably has two guides opposite one another in the transverse direction, the two holding areas of one of the holding projections being arranged in the operating position of the plug-in body between the two guides and in each of the guides. The plug-in body thus extends at least with a transverse section between the two guides. The plug-in body particularly preferably extends with its entire transverse extent between the two guides. By providing the two guides and the two holding projections, a particularly reliable fixation of the first plug-in device relative to the connector can be ensured. In a particularly preferred embodiment, in which, as explained, two holding projections are provided, two holding webs opposite one another in the transverse direction each have a guide section as explained above. For example, this guide section can run along a section of the connector or of the support rail that delimits the guide of the connector or of the support rail. This allows a particularly reliable fixation of the plug-in body relative to the connector or the mounting rail with respect to the transversal direction, whereby by specifying the distance between the guide sections of the holding webs opposite each other in the transverse direction and the distance between the two guides with respect to the transversal direction, the game be fixed along the transversal direction between the connector and the plug-in body while maintaining said fixation with respect to the transversal direction. Particularly preferably, a further guide section is provided at a vertical end of the plug-in body in the transverse direction between the two holding projections, which in the operating position is arranged in a longitudinal groove provided in the connector and is guided laterally.

In one embodiment, the holding areas, in particular the holding webs, are each arranged on an axial end area of the axis of the holding projection. In this way, the tiltability of the plug-in body relative to the connector can be simplified as much as possible, since the arrangement of the holding areas in the axial end areas of the axle enables the axis to extend as large as possible between the plug-in body and the holding areas, so that the axle is deformed relative to the plug-in body is favored. At this point it should be pointed out that the term “axis” in the present application must not be understood in the sense of an axis about which the holding areas can be freely rotated. Rather, the axis designates the section of the holding projection via which it is connected to the plug-in body. Tilting of the plug-in body relative to the connector can be made possible, for example, via a torsion of the retaining projection in the area of its axis and / or via a twistability or bendability of the retaining areas, in particular the retaining webs, about a straight line along the transverse direction relative to the axis. The fact that the holding areas are each arranged at an axial end of the axis of the holding projection can preferably allow the holding areas to be spaced from the plug-in body along the transverse direction via the axis by at least 2 mm, preferably by at least 3 mm. The axis is particularly preferably at least in its axial end area, in which the holding areas are arranged are designed in the manner of a hollow cylinder, in particular with a rectangular cross section. It has been found that this ensures the described function of the axis, namely the connection of the holding areas to the plug-in body while ensuring that the plug-in body can be tilted relative to the holding areas.

In one embodiment, a locking lug is arranged on the axis of the holding projection, preferably in a vertical end region of the axis of the holding projection, to which a recess provided in the connector is assigned, wherein in the operating position the locking lug is engaged in the recess to determine the position of the first plug device relative to the connector along the longitudinal direction. As explained, the first plug-in device particularly preferably has a plurality of holding projections, a latching lug being arranged at least on the axis of one of the holding projections, in particular on the axes of several holding projections, to which a corresponding recess is assigned and which engages in the corresponding recess in the operating position is.

In one embodiment, the guide of the connector or the support rail is designed as a longitudinally elongated recess which is open towards a longitudinal end of the connector or the support rail and into which the holding areas of the holding projection of the first plug-in device, in particular the holding areas of all holding projections of the first plug-in device, run can be inserted in the longitudinal direction to reach the operating position, preferably starting from the longitudinal end of the connector. This can particularly simplify the assembly of a lamp according to the invention by means of a system according to the invention, since the first plug-in device can be easily inserted into the connector with the connector along the longitudinal direction can be connected. Particularly preferably, the support rails each have a longitudinal guide into which the connector can be inserted from a longitudinal end of the respective support rail along the longitudinal direction. As a result, the assembly of a lamp according to the invention can be particularly simplified by means of the system according to the invention. Particularly preferably, the connector can be inserted into the first support rail starting from a longitudinal end of the first support rail, after which the first plug-in device can then be inserted into the connector, after which the two support rails can then be connected to one another by means of the connector while they are mutually longitudinal and the connector is pushed into the second mounting rail in the longitudinal direction starting from the longitudinal end of the second mounting rail facing the first mounting rail, the second plug-in device being insertable into the first plug-in device while the connector is being pushed into the second mounting rail. As a result, the assembly of the lights according to the invention can be particularly simplified by means of the system according to the invention.

In one embodiment, the support rails each have a cross-section perpendicular to the longitudinal direction in the manner of a U-shape with a U-bottom and two U-side walls, which run away from the U-bottom along the vertical direction and which along the transverse direction through the U- Connected to the ground. Particularly preferably, the connector has a cross-section perpendicular to the longitudinal direction in the manner of a U-shape with vertically extending connector side walls and transversely extending connector base, wherein in particular in the two vertically extending connector side walls and / or in the two vertically extending support rail Side walls each have a guide. Let the design of the mounting rail and / or connector with a cross section in the manner of a U-shape The mounting rail and / or connector can be produced particularly easily and inexpensively with sufficient stability. By designing both support rails and connectors with a cross section in the manner of a U-shape, the sliding into one another along the longitudinal direction of the connector into the support rails with sufficient fixation of the support rails to one another can be particularly favored. Through the formation of two guides in the two connector side walls and the provision of a retaining projection on each of the two opposite sides of the plug-in body in the transverse direction, the retaining areas of the two retaining projections being arranged in one of the two guides in the operating position In a very simple manner, a very reliable fixation of the first plug-in device relative to the connector can be made possible.

The invention also relates to a plug-in device for a system according to the invention for realizing a luminaire which is elongated in the longitudinal direction. The plug-in device is designed to be connected, in an operating position, to a first conductor rail which is elongated in a longitudinal direction and which is arranged within a cross section of a first carrier rail which is elongated in the longitudinal direction, the cross section running perpendicular to the longitudinal direction and along a vertical direction at one end is open and is delimited along a transverse direction by two side walls, and to be connected to a second, corresponding plug-in device, which is connected to a second power conducting rail formed elongated in the longitudinal direction and is arranged within a cross section of a second longitudinally elongated support rail, wherein the cross section runs perpendicular to the longitudinal direction and along the vertical direction is delimited by two side walls of the second support rail and the first and second support rails are arranged next to one another in the longitudinal direction, a connector being arranged on the support rails and connecting the two support rails to one another. The plug-in device has a plug-in body, with a retaining projection being provided on at least one side of the plug-in body delimiting the plug-in body perpendicular to the longitudinal direction, which has an axis via which it is connected to the plug-in body and which has two holding areas that extend from the Extend the axis along the lengthwise direction for at least 5 mm from the axis. The plug-in device is designed for inserting the two holding areas of the holding projection in a guide provided on a connector.

Particularly preferably, the plug-in device has a holding projection on each of the two opposite sides of the plug-in body in the transverse direction, each of the holding projections each having an axis via which it is connected to the plug-in body, and each having two holding areas that extend from the respective axis extend longitudinally at least 5 mm from the axis. The plug-in device is preferred for insertion opposite guides formed with the introduction of the two holding areas of each of its two holding projections in each one of the guides.

In Figure 1 the first plug-in device 1 of an embodiment of a system according to the invention is shown schematically. Out Figure 1 it can be seen that the plug-in device 1 has a plug-in body 100, on the two opposite sides of which in the transverse direction Y a holding projection is provided. Each of the holding projections has an axis 10, via which it is connected to the plug-in body 100, and two holding areas which, starting from the axis 10, extend in the longitudinal direction X over at least 5 mm away from the axis 10.
