    LIGHT LINE SYSTEM FLUSH WITH THE CEILING
    The present invention relates to a fastening spring for receiving and securing a light support rail, a light strip system having such a fastening spring and a light support rail, and a method for the assembly of the aforementioned light strip system.
    Conventional trunking systems are already known from the prior art. In this context, reference is made in particular to the TECTON, TRINOS and ZX2 trunking systems developed by the applicant. Examples are the documents DE 100 25 646 A1 and EP 2 151 899 A2, which describe individual aspects of these trunking systems.
    In the trunking systems known from the prior art, in particular a longitudinal support rail is the central supporting element for holding parts and electrical components of a trunking. The power supply for the lamps and the other electrical components is also often found within the Mounting rail. The mounting rail is usually designed to be U-shaped and open towards the bottom. For the releasable attachment of the mounting rail to cable suspensions, ceiling or wall surfaces, the mounting rails are designed on their top side in such a way that retaining clips can engage in rear pulls formed on the top side of the mounting rail. Direct attachment of the trunking system to a ceiling surface is conventionally achieved by screwing the retaining clips to the ceiling.
    An essential technical requirement for a releasable fastening of the support rail in the retaining clip is that the sometimes high weight forces of the trunking system must be safely removed. Usually, the fastening must provide a load-bearing capacity that corresponds to at least five times the acting weight. In the event that conventional plug and / or spring connections are to be used for the attachment, high tensile forces are required for dismantling, which can come close to the dead weight of the fitter. Therefore, such springs are designed to be positively locked in such a way that they cannot be released non-destructively by means of tensile force. During dismantling, a tool, such as a screwdriver, is usually attached to the tongue in order to lever it out of the groove. This requires access to the spring, which previously prevented it from being built flush with the ceiling. Previously, if you wanted to install a light strip flush with the ceiling, the state of the art only provided assembly springs that trigger on tensile force (according to the standard with five times the weight); this with the disadvantages mentioned. This is an unfavorable condition for assembly practice. In addition, when handling such connecting elements, due to the high weight, the safety of the fitter during assembly and disassembly cannot be satisfactorily guaranteed. The freedom in the design of trunking systems is therefore significantly restricted.
    Already existing alternative connecting elements, such as the aforementioned retaining clip, are often associated with complex assembly and greater interventions in the building fabric. Furthermore, it is to be regarded as disadvantageous in connection elements of this type that the upper edge of the support rail is at a certain distance from the ceiling, as a result of which the aesthetics and effect of the trunking system are reduced.
    The distance results on the one hand from the fact that the screws used to attach the retaining clip to the ceiling surface themselves require a certain height, so that there is always a certain gap between the upper edge of the mounting rail and the ceiling surface. Furthermore, when using such connecting elements for the assembly and disassembly of the trunking system, it is necessary that the support rail in the connecting element, in particular the retaining clip, is accessible at points relevant to the fastening.
    It is therefore an object of the present invention to provide a fastening spring for receiving and fastening a light support rail, a light strip system and a method
    provide for the assembly of the aforementioned trunking system, with which on the one hand a distance between the upper edge of the trunking and the ceiling surface is reduced or even avoided and on the other hand a secure attachment for the trunking of the trunking system is provided.
    [0008] This object is achieved by the subject matter of the independent claims. The dependent claims develop the central concept of the present invention in a particularly advantageous manner.
    A first aspect of the present invention relates to a fastening spring for receiving and fastening a light support rail.
    A “spring” is generally understood to mean a mechanical component that is intended to withstand or exert a compressive or tensile force.
    The fastening spring according to the invention, seen in side view, has a substantially U-shaped cross section with two fastening legs and a supporting leg connecting the fastening legs for mounting on a mounting surface.
    According to the invention, “essentially U-shaped” is understood to mean that the cross-section of the fastening spring in side view can deviate from the U-shape within certain permissible tolerances and still has the shape of a U or at least a C. The at least partial mirror symmetry of the cross section with respect to an axis of symmetry orthogonal to the fastening leg can be cited as the minimum dimension for assessing the U-shape of a cross section.
    Furthermore, according to the invention, a “mounting surface” is understood to mean the area of a surface of an objective object which is provided for fastening the fastening spring.
    Each of the fastening legs has a first fastening section for providing a form-fitting connection and a second fastening section for providing a force-fitting connection.
    According to the invention, a “positive connection” is understood to mean a mechanical connection in which the actual inhibition of freedom of movement is achieved by one of the at least two connection partners by means of a positive connection. A form fit is established in that the partners to be connected are firmly connected to one another because one of the connection partners is in the way of another.
    Furthermore, according to the invention, a “non-positive connection” is understood to mean a mechanical connection in which the actual inhibition of freedom of movement is achieved by one of the at least two connection partners by a force counteracting the movement (e.g. frictional force due to static friction).
    It is also pointed out that in a form-fitting connection according to the invention, forces that restrict freedom of movement can also occur, such as clamping forces. The actual inhibition, however, is achieved by the positive locking of the connection partners. This can be used in the same way for the non-positive connection according to the invention.
    The fastening spring according to the invention consequently provides a fastening element by means of which, for example, a light mounting rail can be received and fastened by a form-fitting and / or force-fitting connection. Due to the selected U-shaped cross section of the fastening spring, the assembly of the fastening spring on a mounting surface is simplified in particular by the fact that the fastening spring is divided into obvious functional sections and only a single side is provided for fastening on the mounting surface. With such a design it can be achieved that the assembly on site is significantly simplified.
    In an advantageous embodiment of the invention, the support leg has in particular a mounting portion on which the fastening spring is preferably on the mounting surface
    is attached. In this case, the assembly section, seen in side view, is preferably provided centrally with respect to the fastening spring. Additionally or alternatively, the mounting section can furthermore have elongated holes and / or threads.
    The provision of a mounting section allows the fastening spring to be fastened to the mounting surface in a defined manner. Elongated holes can be used to help with the orientation and positioning of the fastening spring on the mounting surface and to compensate for mounting inaccuracies. The fastening spring can also be used as a template for drilling holes.
    The fastening sections for each fastening leg can also be operated independently of one another. This makes it possible to achieve a connection either by means of a form fit or a force fit. According to this embodiment, the fastening spring thus has no direct (kinematic) coupling of the first and second fastening sections.
    The first fastening section can also be connected to the support leg via a first spring arm and the second fastening section via a second spring arm. According to the invention, a “spring arm” is understood to mean an elastic, preferably resilient, component with defined material properties, such as, for example, a certain modulus of elasticity.
    In the aforementioned embodiment, it is thus possible to apply a first defined spring force laterally by means of the first fastening section and a second defined spring force by means of the second fastening section. It is possible to include a component in the mounting spring by pushing it into the spring. For example, by means of a suitable geometry with guide bevels, the spring arms of the spring spread apart and, after overcoming a groove, lock (positively) with the profile. In addition, it is also preferably possible for the first (form-fitting) and / or second spring arms to be spread open, for example by means of a tool, such as a screwdriver, in order to enable the form-fitting fastening of a component in particular to be released from the fastening spring.
    According to an advantageous development of the invention, the fastening spring can also be designed in such a way that the first fastening section is spaced further from the support leg than the second fastening section.
    [0023] It is thus possible to effect the positive coupling at a distance from the non-positive coupling. As a result, a component can be fastened in the fastening spring at different height positions. Furthermore, since in particular the second fastening section, which provides a non-positive connection, is closer to the support limb, such a component can be pressed directly onto the support limb. In this way it can consequently be ensured that the component picked up is always in direct contact with the support leg.
    Furthermore, the first fastening sections can be designed hook-shaped at their distal end with respect to the support leg, preferably as a U-shaped hook. According to the invention, a “distal end of a section” is understood to mean that of the section extension ends which is further away with respect to a position reference.
    As a result of the aforementioned configuration of the first fastening section, a form-fitting connection is made possible by providing hooks.
    The distal end of the first fastening section can be directed essentially at the support leg.
    With such an alignment of the distal end of the first fastening section, the provision of a form-fitting connection within the two fastening legs is made possible in particular.
    According to a further advantageous development of the invention, the fastening spring can also be designed such that the second fastening sections are each V-shaped in side view, the V-shape of the second fastening sections being open laterally to the outside. Furthermore, the second fastening sections can alternatively or additionally have two guide bevels tapering towards one another and a connecting leg connecting the guide bevels, the connecting legs of the two second fastening sections being directed towards one another.
    The aforementioned configuration of the second fastening section thus provides a spring-like element which, by means of the connecting leg, applies a spring force to a component received in the fastening spring. As a result of the orientation of the connecting legs to one another, a clamping force acting from the two fastening legs can also be generated in the direction of the support leg and thus a non-positive connection can be provided.
    A further aspect of the present invention relates to a light strip system which has a light mounting rail for receiving and carrying light components and a fastening spring according to the invention of the type described above. The light support rail has an elongated profiled body which has a coupling section by means of which the light support rail is mechanically connected to the fastening spring in such a way that the light support rail can optionally be moved between a mounting position and an operating position. The coupling section is positively coupled to the first fastening sections in the assembly position and positively coupled to the second fastening sections in the operating position.
    According to the invention, a “mounting position” is understood to mean a position of the light mounting rail connected to the fastening spring, in which the light strip system is usually mounted and adjusted. The “operating position”, on the other hand, describes a position of the light mounting rail connected to the fastening spring, in which the light strip system according to the invention is normally operated.
    The trunking system according to the invention thus makes it possible to move the light mounting rail between two defined fastening positions by means of the mechanical coupling provided. In the respective position, the light mounting rail is connected to the fastening spring either by a form fit or by a force fit. It is particularly advantageous here that the position intended for assembly is assumed by a form-fitting coupling of the two components, which provides a high level of security with regard to the load-bearing capacity, since component movement is prevented by a component blockage. It is also advantageous that the operating position is assumed by a force-fit coupling of the two components in order to facilitate assembly and disassembly. Since only the two aforementioned positions can be assumed when the light mounting rail and fastening spring are connected, it is also ensured that the light mounting rail cannot fall unchecked out of the mounting spring if the frictional connection fails. Instead, the luminaire support rail is held up by the form-fitting connection with the fastening spring.
    If, for example, as previously stated, the first fastening section of the fastening spring is further spaced from the support leg than the second fastening section, it is possible to move the light support rail from the positive connection to the support limb and there by means of the second fastening sections to fix. The fastening force of the second fastening sections acting in the direction of the support leg can ensure that the upper edge of the light support rail is fastened in the fastening spring with as little distance as possible from the support leg. Equally, such an arrangement allows the assembly position to be taken at a greater distance from the support leg, which simplifies handling and assembly of the components.
    The profile body, viewed in the direction of the longitudinal axis, can have a U-shaped cross section
    have two side walls and a bottom wall connecting the side walls. The bottom wall preferably has the coupling section. A space for receiving and carrying light components can also be limited by the bottom wall and the side walls. In particular, the light support rail can also have light components, such as light sources, busbar systems, operating devices and the like, which are preferably partially or completely received in the profile body. In this case, in the operating position, the bottom wall and the support leg can be flush with one another, preferably the bottom wall and the support leg lie flat against one another. In addition, in the operating position, the side walls can preferably surround the support leg on both sides.
    The U-shaped cross section of the light mounting rail consequently delimits a space which is open on one side and in which light components and other parts can be accommodated. Thus, a receiving space for such components is provided with simple means. The provision of the coupling section on the bottom wall also allows the cross-sections of the fastening spring and the light support rail to be oriented in the same way. The bottom wall and support legs can thus represent the surface oriented upwards, so that the bottom wall can be arranged as flush as possible with the support legs. If the bottom wall and support limb are aligned flush in the operating position, it can be achieved in particular that there is no distance between the mounting surface and the light support rail. This aesthetic effect can also be increased in that the side walls surround the support leg on both sides. Furthermore, the arrangement is protected from environmental influences by the side walls by such a design.
    Furthermore, the light support rail, in particular the bottom wall, can have a recess in the direction away from the support leg in order to delimit a receiving space in the operating position with the support leg.
    Such a configuration makes it possible to provide a receiving space for any protruding parts of the fastening means used for mounting the fastening spring on the mounting surface. Such a part could, for example, represent a protruding screw head. This makes it possible to position the light support rail flush with the support leg despite the protrusion.
    The support leg can furthermore be spaced further from the profile body, preferably the coupling section or the bottom wall, in the assembly position than in the operating position. Furthermore, in the assembly position, the first fastening sections can be accessible from the side in order to detach the light support rail from the fastening spring. In addition, the light mounting rail can be movable in the assembly position along the direction of extent of the profile body.
    This makes it possible to significantly facilitate the assembly of the light mounting rail. This is achieved on the one hand by the greater distance between the light mounting rail and the support leg, which can already be connected to the mounting surface, and on the other hand by the lateral accessibility to the first fastening sections. This makes it possible to use additional tools, such as a screwdriver, for assembly. The movability of the light support rail in the assembly position also enables the positioning of the individual light support rails to one another in terms of manageability and accuracy, especially in the case of larger trunking systems with a large number of light support rails and fastening springs.
    In a further embodiment of the light strip system according to the invention, the light support rail and the fastening spring have corresponding fixing means for fixing the light support rail with the fastening spring in the operating position, preferably by additional fixing means.
    This makes it possible to additionally fasten the light support rail to the fastening spring by the further fastening means and to further exclude a loosening of the fastening of the light support rail in the operating position.
    Another aspect of the present invention also relates to a method for the assembly of a trunking system, having the following steps:
    a. Providing a trunking system according to the invention, that is, according to the type described above,
    b. Assembly of the fastening spring on a mounting surface,
    c. Insertion of the light support rail into the fastening spring and positive coupling of the light support rail with the first fastening section in the assembly position,
    d. Moving the light support rail into the operating position for non-positive coupling of the light support rail with the second fastening section.
    [0043] The method can furthermore have further steps, such as, for example, the process in which the light support rail is moved in the assembly position along its longitudinal axis direction with respect to the fastening spring for position adjustment; is moved, for example, for the axial merging or plugging together of two or more (that is to say of several) light support rails.
    The aforementioned method thus ensures that a light mounting rail of the light strip system according to the invention is not spaced apart from the mounting surface in the operating position, but rests flush against it. Furthermore, the assembly and disassembly of the trunking system can be simplified by the method. In addition, it can be achieved by the method that only a minimal number of bores for the fastening springs have to be provided in the mounting surface, since the fastening in the operating position is achieved via a non-positive connection of the fastening spring.

    FIG. 1 shows a side illustration of a fastening spring 100 according to the invention for receiving and fastening a light mounting rail 200, which is shown as an example in FIG. 2 in a side illustration. The fastening spring 100 and the luminaire support rail 200 are components of a light strip system 300 according to the invention, which is shown in the other FIGS. 3 to 8 in different views and by different exemplary embodiments.
    As stated above, a side view of the Be according to the invention is shown in FIG
    fixing spring 100 shown. The fastening spring 100 has a substantially U-shaped cross-section when viewed in side view. The cross section has two fastening legs 141, 142 and a support leg 130 connecting the fastening legs 141, 142. The support leg 130 is provided for the assembly of the fastening spring 100 on a mounting surface MF (not shown in FIG. 1).
    The fastening spring 100 is preferably made of a metallic material such as steel. Alternatively, however, it is also conceivable to use plastics such as elastomers or thermosetting plastics. The fastening spring 100 can preferably be designed as an integral component, but a multi-part structure is also conceivable. The fastening spring 100 can be produced, for example, depending on the nature of the material used, by means of stamping / bending processes, injection molding processes or generally customary plastic processes. The cross section of the fastening spring 100 in the exemplary embodiment according to FIGS. 1 and 2 to 8 is symmetrical. Furthermore, however, it is also conceivable to configure the cross section of the fastening spring 100 asymmetrically or to adapt it in some other way.
    The fastening spring 100 also has a first fastening section 110 on each of the fastening legs 141, 142, with which a form-fitting connection is provided.
    The first fastening sections 110 can be designed to be hook-shaped at their end 112 which is distal with respect to the support leg 130. FIG. 1 shows a preferred design of the distal end 112 as a U-shaped hook, wherein the distal end 112 can be designed essentially directed towards the support leg 130.
    Through the first fastening sections 110, the form fit can thus be achieved, for example, in that the partner to be connected, in particular the light mounting rail 200 to be received, is enclosed between the support leg 130 and the distal ends 112 of the fastening sections 110 and thus a movement of the connection partner in Way stands.
    Alternatively, however, it is also conceivable that the distal ends 112 of the first fastening sections 110 have other shapes or, for example, are only directed towards the respective opposite fastening legs 141, 142. Furthermore, it is also conceivable that the distal ends 112 of the first fastening sections 110 protrude laterally outward from the cross section. Alternatively, the distal ends 112 can also be designed as a mirror image of the embodiment shown in FIG.
    Furthermore, each of the fastening legs 141, 142 has a second fastening section 120, by means of which a non-positive connection is provided. As shown in FIG. 1, for example, the second fastening sections 120 can each have a V-shape in side view, the V-shape of the second fastening sections 120 being open laterally outward. For this purpose, the second fastening sections 120 can have two guide bevels 122, 123 tapering towards one another and a connecting leg 124 connecting the guide bevels 122, 123, which are directed towards one another. Alternatively, however, it is also conceivable to provide the second fastening sections 120 differently from this configuration, for example as a laterally inwardly or outwardly directed semicircle, in an S or Z shape or in any other configuration with the deflection of the second fastening sections 120 a force in the direction of the support leg 130 can be caused. A particular advantage of the embodiment of the second fastening section 120 shown in FIG. 1 is, for example, that the outwardly protruding areas of the second fastening section 120 can be used for assembly or disassembly. Thus, for example, the force-fit connection can be released by bending the second fastening sections 120.
    The first and second fastening sections 110, 120 for each fastening leg 141, 142 can also be operated independently of one another. It is thus possible, for example,
    to laterally deflect the fastening legs 141, 142 shown in FIG. 1 when the first fastening sections 110 are operated, without causing a deflection of the second fastening sections 120. Alternatively, however, it is also conceivable to provide a coupling between the two fastening sections 110, 120.
    The first fastening section 110 can be connected to the support leg 130 via a first spring arm 111 and the second fastening section 120 via a second spring arm 121. The two fastening legs 141, 142 can thus each be composed of the first spring arm 111 and the second spring arm 121 or each have the two spring arms 111, 121. In particular, it is also conceivable that each of the two spring arms 111, 121 has a defined spring stiffness. The spring stiffnesses of the two spring arms 111, 121 can be the same or different from one another. The two spring arms 111, 121 can be formed by different materials or by differently surface-treated materials, such as metals with different degrees of hardness.
    FIG. 1 shows that the first fastening section 110 can be spaced further from the support leg 130 than the second fastening section 120. Furthermore, it is also conceivable to reverse this arrangement or to arrange the two fastening sections 110, 120 at the same distance from the support leg 130 .
    As already briefly mentioned at the beginning, the support leg 130 is provided for mounting the fastening spring 100 on the mounting surface MF. For this purpose, the support leg 130 can have a mounting section 131, to which the fastening spring 100 is preferably fastened to the mounting surface MF. The mounting section 131 can be provided in the center of the fastening spring 100, as seen in side view, and alternatively or additionally have elongated holes and / or threads. A fastening of the fastening spring 100 on the mounting surface MF is shown in particular in FIGS. 3 to 8.
    FIGS. 3 to 8 show representations of the light strip system 300 according to the invention. In addition to the previously presented fastening spring 100, this has at least one light support rail 200 with which light components 500 are carried and received. FIG. 2 shows a simplified exemplary side view of such a light support rail 200.
    The light mounting rail 200 has an elongated profile body 210. The profile body 210 can have a U-shaped cross section, viewed in the direction of the longitudinal axis, which is formed from two side walls 211, 212 and a bottom wall 213 connecting the side walls 211, 212. The bottom wall 213 and the side walls 211, 212 delimit a profile body space PR, hereinafter referred to as space PR, for receiving and carrying light components 500 (not shown in FIG. 2).
    Alternatively, however, further cross-sections of the profile body 210 are also conceivable, in particular also closed or asymmetrical cross-sections. The profile body 210 can be made of various materials, preferably of steel or other metals, such as aluminum, or also of plastics. The profile body 210 can be produced by means of different production methods, such as extrusion, forming processes or bending processes. Furthermore, it is also conceivable to design the profile body 210 in such a way that particularly good heat dissipation to the environment can be achieved for heat generated in the space PR. For this purpose, the light mounting rail 200 can have structural elements, in particular cooling ribs and ventilation openings. Furthermore, it is also conceivable to design the profile body 210 in one piece or in several pieces.
    The profile body 210 also has a coupling section 220, which is preferably provided on the bottom wall 213. Alternatively, however, it is also conceivable to provide the coupling section 220 on one of the side walls 211, 212 or by means of a further component (not shown) on a surface of the profile body 210. In FIG. 2, the coupling section 220 is exemplarily formed by a rail-shaped configuration of the bottom wall 213. There
    the cross-section of the profile body 210 along the bottom wall 213 has two laterally outwardly directed projections 221. However, this embodiment of the coupling sections 220 is only to be understood as an example and can be supplemented or replaced as desired by other developments. For example, hook-shaped coupling sections 220 could alternatively also be used.
    Latching elements 240 can furthermore be formed on the light support rail 200 in order, for example, to securely accommodate the light components 500 to be received in the space PR and / or to close the side of the light support rail 200 that is open to the surroundings.
    The light mounting rail 200 can furthermore have a recess 230. The recess 230 is formed in FIG. 2 in particular in the bottom wall 213, but can also be formed in one of the side walls 211, 212. As can be seen in FIGS. 3 to 8, when the fastening spring 100 and the lamp mounting rail 200 are connected, the recess 230 can point away in the direction of the mounting leg 130 in order to delimit a receiving space AR together with the mounting leg 130.
    In the light strip system 300 according to the invention, the light support rail 200 is mechanically connected to the fastening spring 100 by means of the coupling section 220 in such a way that the light support rail 200 can optionally be moved between an assembly position and an operating position. Figures 3, 4 and 8 show in particular the light strip system 300 in the assembly position. In contrast, FIGS. 5 to 7 show the light strip system 300 in the operating position.
    In each of FIGS. 3 to 8, the fastening spring 100 is already fastened by means of a fastening means 400, in particular a fastening screw 400, to its support leg 130 on the mounting surface MF.
    Insertion of the light support rail 200 into the fastening spring 100 can be achieved, for example, by inserting the light support rail 200 with the bottom wall 213 in the direction of the support leg 130 into the fastening spring 100. After assembly, the side walls 211, 212 can be in direct surface contact with the surface of the first spring arm 111.
    FIG. 4, which shows a detailed representation of the trunking system 300 shown in FIG. 3, is particularly suitable to illustrate how the coupling section 220 of the light support rail 200 is coupled to the first fastening sections 110 of the fastening spring 100 in the assembly position.
    In the example shown, the light mounting rail 200 rests on the distal ends 112 of the first fastening sections 110 by means of the coupling sections 220. The distal ends 112 in the figures are each designed as U-shaped hooks, but this design is not absolutely necessary and can be adapted accordingly if necessary.
    The form-fitting coupling of the light support rail 200 with the fastening spring 100 is preferably designed such that the light support rail 200 can be moved in the assembly position along the direction in which the profile body 210 extends. In this way, for example, in a trunking system 300 with multiple light mounting rails 200 and multiple fastening springs 100, the individual light mounting rails 200 can be moved relative to one another in order to allow the components to be connected. Connecting intermediate pieces or bridge parts are usually used for this. It is also clear that it can be particularly advantageous during assembly if the light strip system 300 is designed in such a way that the first fastening sections 110 are accessible from the side in the assembly position in order to be able to detach the light support rail 200 from the fastening spring 100 again.
    The lamp support rail 200 can be moved from the mounting position by sliding it into the operating position.
    According to the invention, the coupling section 220 is in the operating position with the second
    Fastening sections 120 coupled positively. The operating position is shown, for example, in FIGS. 5 and 6, the detailed view of FIG. 6 being particularly suitable for the detailed description of this position.
    In the exemplary embodiment shown, the force-fit coupling takes place in particular in that the second fastening sections 120 are deflected laterally outward from their non-deflected state, as shown, for example, in the operating position presented above, and then brought into contact with the coupling sections 220 . A jamming or latching of the light support rail 200 with the fastening spring 100 occurs when the coupling sections 220 have been received by the second fastening sections 120 in such a way that a force directed towards the support leg 130 is generated by which the light support rail 200 is held. In the exemplary embodiment according to FIG. 6, the force acting here is static friction between the projection 221 and the surface of the second fastening section 120, which counteracts the weight of the light mounting rail 200. This makes it clear that the coupling between the coupling section 220 and the second fastening section 120 has both components of a form-fitting and a frictional connection. However, the latching / fixing is primarily achieved by the force and not by the form fit.
    It can also be seen in FIG. 6 that the trunking system 300 is preferably designed in such a way that in the operating position the bottom wall 213 and the support leg 130 are flush with one another and / or rest flat against one another.
    In addition, the trunking system 300 is preferably designed in such a way that the side walls 211, 212 of the light mounting rail 200 in the operating position surround the support leg 130 of the fastening spring 100 on both sides.
    This can be achieved, for example, by a corresponding design of the light mounting rail 200, as shown in FIGS. 2 to 8. In this case, the light support rail 200 in particular has further recesses on the respective lateral edge regions of the bottom wall 213, in which the first fastening sections 110 can be completely received. Furthermore, the further recesses have a lateral protrusion with respect to the bottom wall 213, so that the side walls 211, 212 reach up to the mounting surface MF. Alternatively, however, the fastening spring 100 could also have a corresponding design in order to achieve this configuration.
    FIG. 6 also illustrates the function of the receiving space AR delimited by the recess 230 and the support leg 130 according to an advantageous development of the invention. With this configuration, the screw head 401 of the fastening screw 400 can be completely received by the light support rail 200 in the operating position. As a result, a particularly flush arrangement of the light mounting rail 200 in the fastening screw 100 is achieved.
    The light support rail 200 and the fastening spring 100 can furthermore have corresponding fixing means for fixing the light support rail 200 with the fastening spring 100 in the operating position. Additional fixing means can also be provided, with which the corresponding fixing means of the fastening spring 100 and the lamp support rail 200 are connected to one another. It is also conceivable, for example, that threaded openings are provided on the support leg 130 which correspond to through bores in the base wall 213 in order to secure the light support rail 200 to the fastening spring by means of additional screws.
    A comparison of the operating position, as shown for example in FIG. 6, and the assembly position, as shown for example in FIG. 4, reveals a further preferred embodiment of the trunking system 300 according to the invention. The support leg 130 is preferably further from the profile body 210 in the assembly position , preferably the coupling section 220 or the bottom wall 213, spaced apart than in the operating position. The light mounting rail 200 can thus be fastened within the fastening spring 100 in two fastening planes that are spaced apart from one another and essentially parallel to one another.
    The lighting support rail 200 can have lighting components 500, such as lighting means 510, busbar system 520, operating devices and the like, which are preferably partially or completely received in the profile body 210. FIGS. 7 and 8 show examples of such components to be accommodated and their attachment in the light mounting rail 200. The current collectors 530 in FIGS. 7 and 8 are implemented by alternative configurations.
    The trunking system 300 can furthermore also have control units, internet-capable devices or modules and devices by means of which LiFi and / or WiFi applications can be implemented. Furthermore, it is also conceivable that the light strip system 300 has several light support rails 200 and several fastening springs 100.
    Finally, an assembly method for the trunking system 300 according to the invention is described.
    The method according to the invention for assembling the trunking system 300 has in particular the following steps:
    First of all, the aforementioned light strip system 300 according to the invention is provided. The fastening spring 100 is then mounted on the mounting surface MF, for example by means of an additional fastening means 400 which interacts with a corresponding further fastening means of the mounting surface MF. For example, the installation of a wall plug in the ceiling is mentioned here, into which a screw can be inserted.
    This is followed by the insertion of the lamp support rail 200 into the fastening spring 100 and a positive coupling of the lamp support rail 200 to the first fastening section 110 in the assembly position. No tools have to be used for this in order to produce the form fit of the components. The individual lamp support rails 100 can be moved in the assembly position along their longitudinal axis direction with respect to the fastening spring 100. This in particular for position adjustment, for example in such a way that an axial merging or plugging together of two or more support rails to one another is made possible.
    The light support rail 200 is then moved from the assembly position into the operating position and there is a force-locking coupling with the second fastening section 120.
    FIG. 7 also shows a further optional method step in which, after the fastening spring 100 and the light mounting rail 200 have been successfully assembled in the operating position, a light component 500 is inserted into the light mounting rail 200. The luminaire components 500 can have latching means 241 for fastening which correspond to the latching elements 240 provided on the luminaire support rail 200.
    The present invention is not restricted by the exemplary embodiments described above, provided that it is covered by the subject matter of the following claims. In particular, all the features of the exemplary embodiments can be combined and interchanged with and with one another in any way.
