Description

The invention relates to a system for realizing a luminaire elongated in a longitudinal direction according to the preamble of claim 1 and to a luminaire realized by means of such a system and to a method for releasing two support rails of the system connected to a coupling of the system.

Systems of this type are designed to create a luminaire that is elongated in a longitudinal direction and comprises a plurality of longitudinally elongated support rails. The support rails are typically used to fix the luminaire to a building structure, for example to a ceiling. The support rails represent a type of basic framework for the luminaire and are designed to accommodate supply lines and preferably to accommodate mounting bodies to which lamps are attached. An infrastructure for the luminaire is thus provided via the support rails. Electrical functional elements of the luminaire are usually attached to the mounting bodies, for example circuit boards with LEDs, radio modules, electrical cables and/or operating devices. When installing the luminaire, the respective support rail is usually first attached to the building structure and then the mounting body, which is connected to at least one of the electrical Functional elements of the luminaire are fitted, fixed to the support rail, so that the support rail and mounting body form an interior space in which essential elements of the luminaire are arranged, for example circuit boards, operating devices, contact devices, etc. Typically, the support rail and mounting body are each elongated in a longitudinal direction, the longitudinal extent preferably being at least five times the extent perpendicular to the longitudinal direction. The support rail usually has a U-shaped cross-section perpendicular to the longitudinal direction, which extends in a vertical direction and in a transverse direction and is open at one vertical end and which is formed by a support rail base and two support rail side walls. The support rail side walls thus run vertically away from the support rail base, and the support rail base connects the support rail side walls which are spaced apart transversely from one another. Depending on requirements, the support rail base and the support rail side walls can have contours or recesses. The support rail base and the support rail side walls usually together form an interior space which is at least partially enclosed by the support rail side walls and the support rail base. The interior space is thus defined by the support rail. Usually, all support rails of a system have the features described here. A generic system has at least a first and a second support rail, which are connected to one another at their mutually facing longitudinal ends to form the luminaire. Usually, they form a common interior space, which extends between the support rail side walls of both support rails and the support rail base of both support rails, elongated along the longitudinal extent of both elongated support rails. extends. The two support rails are fixed to one another by means of a coupling which has a coupling body which has a U-shaped cross-section which is formed by a coupling base and two coupling side walls of the coupling body. The coupling side walls thus run vertically away from the coupling base, and the coupling base connects the coupling side walls which are spaced apart transversely from one another. The U-shaped cross-section of the coupling body is preferably open at its end opposite the coupling base. Typically, each of the support rails has a substantially constant cross-section perpendicular to the longitudinal direction, the cross-section preferably being identical except for recesses and/or punchings in the support rail base and/or support rail side walls. The cross-section of all support rails is often substantially the same. Typically, the support rails are fixed relative to one another by the coupling perpendicular to the longitudinal direction and in particular also by means of the coupling in the longitudinal direction. In an operating state of the system in which the first and second support rails are fixed to one another, the coupling is usually arranged in the two support rails in such a way that the coupling base runs along both support rail bases and each of the coupling side walls rests against a respective one of the support rail side walls assigned to it. The coupling is particularly preferably arranged with a first longitudinal section in the first support rail and with a second longitudinal section in the second support rail, the longitudinal sections being directly adjacent to one another and together forming the coupling, the coupling side walls being pressed vertically with the first support rail in the first longitudinal section and the coupling side walls being pressed vertically with the second support rail. Thus, the arrangement of the coupling body in the two support rails preferably determines a relative position of the support rails in both the vertical and transverse directions.

The support rail is usually attached to the structure via its support rail base. The mounting body is usually arranged at the open vertical end of the support rail, so that the mounting body vertically delimits the interior defined by the support rail and the interior is enclosed by the support rail and mounting body perpendicular to the longitudinal direction. At least in some longitudinal sections, the enclosure of the interior, which is formed by the support rail and mounting body, can be interrupted, for example to allow access to the interior, for example for air supply. The interior is preferably continuously enclosed over at least 80%, in particular at least 90% of its longitudinal extent, in particular over its longitudinal extent. The mounting body often has a cross-section perpendicular to the longitudinal direction, which comprises a mounting body base extending in the transverse direction and mounting body side walls extending vertically away from the mounting body base on the two transverse sides of the mounting base. The support rail and mounting body are usually manufactured separately from one another. Particularly preferably, the support rail and/or mounting body and/or coupling are usually each manufactured from a sheet metal by forming. Preferably, the support rail and/or mounting body and/or coupling are each designed as a one-piece, i.e. one-part, component. Usually, the mounting body is connected to the mounting body via a Retaining spring held on support rail retaining anchors of the support rail. Various possibilities for implementing such a retaining spring are known in the prior art. The retaining spring is usually firmly connected to the mounting body and has retaining projections that can be elastically deflected in the transverse direction. The support rail retaining anchors are preferably designed as projections.

To implement a generic luminaire, supply lines are usually provided which are arranged in the interior of the support rails and are supplied by the lamps and/or other electrical functional elements which are arranged on the mounting bodies of the luminaire. A generic system often has a current guide rail which is usually made of plastic, in particular by means of an extrusion process, and which is also elongated in the longitudinal direction, i.e. has an elongated longitudinal extension between both of its longitudinal ends. The current guide rail is usually arranged on an inner side of the support rail facing the interior and is fixed to the support rail, in particular on the support rail base and/or on at least one of the support rail side walls. The current guide rail extends over a significant portion of the length of the support rail, in particular over at least 80% of the longitudinal extension of the support rail. The current guide rail usually has several channels arranged next to one another along the transverse direction, which are open to an access side which is accessible from the interior. The channels preferably extend continuously over the entire length of the current guide rail. In particular, the transverse direction, the longitudinal direction and the vertical direction are perpendicular to each other. In the operating position of the system, in at least some A conductor wire is arranged in each of the channels, and at least one longitudinal end of the current guide rail usually has the conductor wires connected to an external voltage source, via which electrical energy and in particular electrical signals can be applied to the conductor wires. The conductor wires can thus serve as supply lines in the support rails. For this purpose, an electrical connector, in particular designed as an electrical feed device, is usually arranged at the longitudinal end and is electrically connected to the conductor wires. Usually, an electrical connector is provided at each longitudinal end of the current guide rail. The electrical connectors can, for example, be designed as connectors that correspond to one another, for example a first as a plug and a second as a socket. When at least one connector is provided at at least one longitudinal end of the current guide rail, adjacent current guide rails in the longitudinal direction can be electrically connected to one another, so that the conductor wires can form a through-wiring.

The system usually also includes a contact device via which an electrical contact is made between the conductor wires assigned to the current guide rail and at least one electrical functional element of the mounting body. The contact device is usually fixed to the mounting body and ensures an electrical connection of the at least one electrical functional element when the mounting body is held in its intended position on the support rail in which the light is implemented. The contact device is designed to engage in the channels from the access side of the support rail in order to contact the conductor wires.

Generic systems are used in a wide range of applications, for example in warehouses, production halls, supermarkets or open-plan offices, where luminaires with a plurality of support rails and mounting bodies are used. The basic principle of the luminaires manufactured with a generic system is that the support rails form the electrical and mechanical infrastructure of these luminaires, whereas the mounting bodies are attached to the support rails and have the electrical functional elements that are required in the respective application area. Of course, at least some of the electrical functional elements are usually designed as lighting modules with light sources, in particular comprising LED boards. For example, alternatively or additionally, other electrical functional elements can also be provided on the respective mounting body, such as a presence sensor (e.g. infrared sensor), a camera, a radio module, etc. The electrical functional elements are usually fixed to the mounting body.

In typical applications, generic systems are used in such a way that several luminaire assemblies, each of which comprises a support rail designed as described, are arranged one behind the other in the longitudinal direction and connected to one another. Further components of the respective luminaire assembly can be arranged on or in the support rails of the luminaire assemblies. For example, lamps and supply lines can be attached to the support rails, for example directly to the support rails, for example by providing a mounting body designed as described above and/or a current guide rail designed as described above. For example, each luminaire assembly can each comprise a support rail, a current conducting rail and a mounting body and in particular a coupling fastened to the support rail. The luminaire assemblies are arranged one behind the other in the longitudinal direction, the support rails of the respective luminaire assemblies being mechanically connected to one another by means of the coupling and the supply lines which run in the support rails, in particular the conductor wires arranged in the current conducting rails of the luminaire assemblies, being electrically connected to one another in pairs, i.e. one conductor wire of the first luminaire assembly with one conductor wire of the second luminaire assembly. This makes it possible to create very elongated luminaires, as is required in a large number of applications. A luminaire of the respective system thus comprises a large number of support rails and in particular a large number of mounting bodies and/or current conducting rails or a large number of luminaire assemblies, which are each connected to one another as explained.

Since generic luminaires usually have a considerable length in the longitudinal direction, often more than 5 m, often more than 10 m, often more than 20 m, often more than 50 m, it is necessary to connect a large number of support rails to one another using a generic system in order to create the luminaire. The support rails are usually delivered with the coupling arranged in the respective support rail at the factory with one longitudinal section and protruding from the support rail with another longitudinal section, with which it can then be inserted into another support rail to fix the two support rails together. Such a fixation of the two support rails to one another using the coupling should be as simple and be quick to carry out and at the same time ensure that the two support rails are reliably fixed to one another. It should be noted that both the support rails and at least the coupling body of the coupling are usually made from sheet metal by means of forming, with the coupling body being made from a thicker sheet metal and having a higher rigidity than the support rails. Generally preferably, the sheet metal from which the coupling body is formed has a thickness of at least 1 mm, in particular at least 1.2 mm, in particular between 1 mm and 2 mm, so that the coupling side walls and the coupling base have such a thickness or wall thickness. Generally preferably, the sheet metal from which the support rail is formed has a thickness of less than 70% of the thickness of the sheet metal from which the coupling body is formed, with the support rail side walls or the support rail base having such a thickness or wall thickness. In order for the connection of the support rail by means of the coupling to be sufficiently robust, the coupling in both support rails must be fastened with its coupling side walls tightly against the support rail side walls of the two support rails. In addition, for reasons of cost and space, the coupling should extend as little as possible into the clear cross-section of the support rails when arranged in the respective support rails and take up as little space as possible in the support rails.

In order to ensure the most reliable possible fixation of the support rails relative to the coupling, it is already known to design the coupling with at least one scratch spring, which is deflected from its rest position in the operating state of the system in which two support rails are connected to each other by the coupling and presses against each of the two Support rails, each with a spring section. Such a scratch spring can prevent the support rails from moving apart in the longitudinal direction to a particularly large extent, since such a movement apart would only be possible by overcoming the scratch contact and/or deformation of the scratch spring. Generally, the coupling body is preferably divided into two longitudinal sections, wherein in the operating state it is arranged with its first longitudinal section in the first support rail and with its second longitudinal section in the second support rail and determines the relative position of the two support rails to one another both with respect to the vertical direction and with respect to the transverse direction, whereas the relative position with respect to the longitudinal direction is determined by the interaction of the coupling body and the scratch spring. Particularly preferably, the support rail side walls each form a fixing guide for one of the coupling side walls, wherein in the operating state the coupling side walls are each arranged in the fixing guide assigned to them and are fixed therein both in their transverse position and in their vertical position relative to the respective support rail, which has the support rail side wall with the said fixing guide.

However, the provision of such scratch springs is accompanied by difficulties. On the one hand, such a scratch spring should advantageously be attached to the coupling body in a sufficiently robust manner. On the other hand, such a scratch spring should advantageously ensure sufficient scratch contact with the respective support rail in the operating state. In addition, such a scratch spring should advantageously not take up too much space so that a sufficiently large clear cross-section in the support rails remains at the height of the coupling. In addition, the pressing of the scraper spring with the support rails should advantageously not lead to a destabilization of the coupling body in the support rails. In addition, for maintenance and disassembly purposes, it should also be possible to easily release support rails that are connected to one another by the coupling.

The present invention is based on the object of providing a system or a method or a luminaire with which at least one disadvantage that exists in systems or luminaires or methods of the generic type or known from the prior art is at least partially eliminated.

As a solution to the problem underlying the present invention, the invention proposes a system with the features according to claim 1. The system is designed to realize a lamp that is elongated in a longitudinal direction and comprises several longitudinally elongated support rails and at least one coupling for mechanically connecting a first and a second of the support rails. In an operating state of the system, the coupling is arranged with a first longitudinal section in the first support rail and with a second longitudinal section in the second support rail and fixes these support rails to one another. The coupling has at least one scratch spring with a first and a second spring section, which are deflected in the operating state starting from a rest position, wherein in the operating state the first spring section presses against the first support rail with a first spring force and the second spring section presses against the second support rail with a second spring force. The rest position refers to the position of the scratch spring in which it is is when the coupling is not in contact with other components. The deflection from the rest position, which occurs in the operating state, generates a spring force which presses the two spring sections against the support rail assigned to them. Each of the two spring sections has at least one scratching nose. In the operating state, the scratching spring is thus deflected in a spring-elastic manner. In the operating state, each of the spring sections presses with its at least one scratching nose against the support rail assigned to it. The system comprises a disassembly tool which, in a released state of the system, is pressed against the scratching spring while deflecting the scratching spring in such a way that the scratching nose of the second spring section of the scratching spring is spaced from the second support rail. In the operating state of the system, the disassembly tool is in a first position, and in the released state it is in a second position, into which it is moved starting from the first position. Preferably, the coupling further comprises a guide in which the disassembly tool is arranged in a displaceable manner, wherein the disassembly tool is mounted in the guide and can be displaced between a first position and a second position on a displacement path defined by the guide. Displaceability along the displacement path defined by the guide is thus ensured while the disassembly tool is mounted in the guide. Preferably, by being mounted in the guide, the disassembly tool is fixed to the coupling by the guide in a captive manner. Preferably, the displacement path has defined displacement path ends, wherein the disassembly tool can only be displaced when mounted in the guide between the displacement path ends and thus the guide adjusts the position of the disassembly tool to a position along the displacement path between its displacement path ends. In the operating state, the disassembly tool is arranged in the first position. In a release state of the system, the disassembly tool is arranged in the second position. In the second position, due to the corresponding design of the coupling and the disassembly tool, the disassembly tool is pressed against the scratching spring while deflecting the scratching spring in such a way that the scratching nose of the second spring section of the scratching spring is spaced away from the second support rail. In one embodiment, in the second position, due to the corresponding design of the disassembly tool and the coupling, the disassembly tool is further pressed against the scratching spring while deflecting the scratching spring in such a way that the scratching nose of the first spring section of the scratching spring is spaced away from the first support rail. In another embodiment, in the second position, only the scraper nose of the second spring section is spaced from the second support rail, as explained, whereas the scraper nose of the first spring section presses against the support rail in the second position of the disassembly tool in the same way as in the first position, wherein the disassembly tool is mounted in the guide and can be displaced between the first, second and third positions on the displacement path defined by the guide, wherein the disassembly tool is arranged in the second position in a first release state, as explained above, and presses against the scraper spring while deflecting the scraper spring in such a way that the scraper nose of its second spring section is spaced from the second support rail, whereas the disassembly tool is arranged in the third position in the second release state of the system and is pressed against the scraper spring while deflecting the scraper spring in such a way that the scraper nose of the first spring section of the scraper spring is spaced apart from the first support rail, wherein in particular in the third position the scraper nose of the second spring section presses against the second support rail in the same way as in the first position, i.e. in the operating state of the system. The coupling preferably comprises at least one scraper spring on each of its coupling side walls, which can be deflected elastically from a rest position. If only one scraper spring is provided, this is preferably arranged centrally on the coupling base with respect to the transverse direction. In one embodiment, at least one scraper spring is arranged on each of the coupling side walls, but not on the coupling base. Particularly preferably, all of the scraper springs are arranged exclusively in a longitudinal region of the coupling which, in the operating state, extends longitudinally from the mutually facing longitudinal ends of the two support rails by less than 10 cm, in particular less than 8 cm, in particular less than 5 cm, in particular less than 3 cm, into both support rails. In embodiments, the system according to the invention can have features which are described here in connection with systems presented as known from the prior art, in particular systems of the generic type.

The invention has the particular advantage that, on the one hand, the scratch spring can ensure that the two support rails are particularly reliably fixed to one another in the operating state, and, on the other hand, the disassembly tool stored in the guide on the coupling still allows the support rails to be easily detached from one another. The disassembly tool is held by the guide on the coupling both in the operating state and in the release state. The guide thus provides the Position of the disassembly tool relative to the coupling, and the guide formed by the coupling also determines the movement of the disassembly tool from the first position to the second position, in particular to the third position, which the disassembly tool must necessarily carry out due to the bearing in the guide so that the system can switch between the above-mentioned states. At this point, it should be noted that in the present case, when explanations refer to the release state, these explanations are always applicable to the first and second release states explained.

In one embodiment, the disassembly tool has a first tool section associated with the first spring section and a second tool section associated with the second spring section, wherein, starting from the operating state, both the first tool section can be pressed against the first spring section to release the scratching nose of the first spring section from the first support rail and the second tool section can be pressed against the second spring section to release the scratching nose of the second spring section from the second support rail, while the disassembly tool, starting from the operating state, is continuously mounted in the guide and is thereby fixed to the coupling. Each of the tool sections is thus associated with one of the spring sections. Preferably, the spring sections and the tool sections are each spaced apart from one another in the longitudinal direction. In the embodiment described here, the scratching spring can be deflected by means of the disassembly tool both by means of the first tool section so that the first spring section is spaced apart from the first support rail and by means of the second tool section so that the second spring section is spaced apart from the second support rail. The deflection of the scratching spring for removing the scratching nose of the respective spring section from the respective support rail generally refers, of course, to a deflection of the scratching spring starting from the state it has in the operating state. In one embodiment, the disassembly tool can, starting from the operating state, only selectively press either the first tool section against the first spring section to release the scratching nose of the first spring section from the first support rail or the second tool section against the second spring section to release the scratching nose of the second spring section from the second support rail, whereby this pressing can also take place one after the other, so that, for example, first the first tool section is pressed against the first spring section to release the scratching nose of the first spring section from the first support rail and then the second tool section is pressed against the second spring section to release the scratching nose of the second spring section from the second support rail, whereby the order can also be swapped. In one embodiment, the disassembly tool can simultaneously press both the first tool section against the first spring section to release the scraper nose of the first spring section from the first support rail and the second tool section against the second spring section to release the scraper nose of the second spring section from the second support rail, starting from the operating state. The scraper spring, coupling body and disassembly tool are designed to correspond to one another. In the operating state, the scraper spring is preferably deflected from its rest position in such a way that its first spring section presses against the first support rail with a first spring force. and its second spring section presses against the second support rail with a second spring force, wherein the deflection generated by the disassembly tool represents an increase in the deflection that the scratching spring or its respective spring section already has in the operating state. Thus, the disassembly tool is preferably designed to increase the deflection of the second spring section in the operating state when it is moved from the first position to the second position and thereby to release the scratching nose of the second spring section from the second support rail, wherein in particular when the scratching spring is moved to the second position or to the third position, the deflection of the first spring section is increased accordingly. Generally preferably, the disassembly tool is in the second position when its second tool section is pressed against the second spring section as explained, by which the scratching nose of the second spring section is released from the second support rail. Generally preferably, the disassembly tool is in the second position when its first tool section is pressed against the first spring section as explained to release its scratching nose from the first support rail or in the third position as explained.

In one embodiment, the coupling body is made of a sheet metal. In one embodiment, the scratch spring is made of a sheet metal. In one embodiment, the disassembly tool is made of plastic, in particular by means of injection molding. The disassembly tool is particularly preferably made of an elastic plastic, so that the disassembly tool is elastically deformable, in particular in a certain direction over its entire extension perpendicular to this direction. By If the disassembly tool is made of plastic, on the one hand a shape that is sufficiently complex for the intended use of the disassembly tool can be easily realized, and on the other hand this can enable a simple connection of the disassembly tool to the coupling, in particular a simple and releasable locking with the coupling for fixing at least the second position and in particular the third position by means of a releasable locking connection. Generally preferably, the coupling body is made of a stiffer material than the disassembly tool. Generally preferably, the coupling body is made of a stiffer material than the scratching spring. Generally preferably, the scratching spring is made of a stiffer material than the disassembly tool. In each case, the focus is on the properties inherent in the material, not on the elastic properties due to the geometric design of the respective component.

The scratching spring is particularly preferably made from a formed sheet metal. The scratching spring is particularly preferably made from a spring sheet metal, whereby the spring properties of the spring sections can be particularly advantageously realized by forming the sheet metal to form the spring sections. The scratching spring and the coupling body are preferably each made in one piece from a sheet metal. The sheet metal from which the scratching spring is made particularly preferably has a sheet thickness that is less than half, in particular less than a quarter of the sheet thickness of the sheet metal from which the coupling body is made. Generally preferably, the fastening section of the scratching spring explained below is rigid and the spring sections are designed to be spring-elastic in themselves, forming the respective spring force in the operating state. The spring force refers to the force with which the spring sections press against the support rail assigned to them due to the deflection of the scratch spring. Particularly preferably, the spring sections each independently form a spring force with which they press against the support rail assigned to them in the operating state.

In one embodiment, the disassembly tool is fixed to the coupling by the guide in a captive manner and is mounted in the guide in such a way that it can only be moved relative to the coupling along the displacement path specified by the guide and between displacement path ends defined by the guide. The disassembly tool is particularly preferably arranged in the second position at one of the displacement path ends. The disassembly tool is particularly preferably arranged in the second position at a first displacement path end, and in the third position at a second displacement path end, with the first and second displacement path ends both limiting the displacement path along the displacement direction of the displacement path specified by the guide.

In one embodiment, in the second position and in particular in the third position, the disassembly tool is pressed between a section of the coupling and the second spring section and this pressing applies a force required to maintain the deflection of the scratch spring in the release state. Similarly, in the second position or in the third position explained, the disassembly tool can be pressed between the section or another section of the coupling and the first spring section and this pressing applies a force required to maintain the deflection of the scratch spring in the The force required for the release state must be applied. The deflection of the scratch spring preferably refers to a deflection of the respective spring section which, in the respective release state, is released with its scratching nose from the support rail assigned to it. The coupling and disassembly tool are therefore preferably designed to maintain, on their own and therefore inherently, the force required to achieve the deflection of the scratch spring in the respective release state, wherein the release state can be maintained particularly preferably by pressing without an external force being required for this, so that starting from the release state, the support rails can be easily released from one another.

In one embodiment, the disassembly tool has a locking device and the coupling has a locking device corresponding to the locking device, wherein the disassembly tool is fixed in its position along the displacement path in the second position and in particular in the third position by the locking device and the locking device engaging with each other. The locking device and the locking device can be designed, for example, as a projection or recess or as a projection arrangement or recess arrangement comprising several projections or recesses. In the release state, the disassembly tool particularly preferably presses against the second spring section with a pressing force that runs in a force direction and has a force amount in order to maintain the deflection of the second spring section, wherein the locking device and the locking device are pressed against each other with a force whose force amount is smaller than the force amount of the pressing force and/or whose force direction corresponds to the force direction of the pressing force is angled. Similarly, in the release state, the disassembly tool can press against the first spring section with a pressing force that runs in a force direction and has a force amount, and the locking device and locking mechanism can be pressed against one another with a force whose force amount is smaller than the force amount of this pressing force and/or whose direction of force is angled to the direction of this pressing force. The pressing between the disassembly tool and the coupling to maintain the release state is therefore particularly advantageous as it is causal for the presence of a sufficient pressing force that is required to maintain it, whereas this pressing force is different from the force with which the locking device and locking mechanism lie against one another. The locking device and locking mechanism can therefore be easily detached from one another and a sufficient pressing force can nevertheless be achieved independently of this.

In one embodiment, the guide and the disassembly tool are designed to correspond to one another in such a way that the displacement path, in particular straight, i.e. linear, runs predominantly in the longitudinal direction or in the vertical direction, in particular runs completely in the longitudinal direction or in the vertical direction, or is at least a section of a circle that can be circled around an axis running perpendicular to the longitudinal direction, wherein the axis preferably runs in the transverse direction or in the vertical direction. When the scratch spring is provided on one of the coupling side walls, the axis preferably runs in the transverse direction. Generally, the displacement path preferably runs at least in sections perpendicular to the direction in which the spring sections in the operating state with the spring force against the support rail assigned to them. Generally preferably, the first and second spring forces with which the first and second spring sections press against the first and second support rails assigned to them in the operating state have a component in the vertical direction, in particular predominantly in the vertical direction, in particular completely in the vertical direction, so that the spring sections each press vertically against the support rail assigned to them.

For example, the first spring section can press against the support rail base with the first spring force in the operating state and the second spring section can press against the support rail base with the second spring force in the operating state, or the spring sections can each press vertically against a wall section of the support rail side walls of the support rails. Particularly preferably, the support rail side walls of the support rails each have a wall projection against which the spring sections each press in the operating state, i.e. each of the spring sections against the wall projection of the support rail side wall of the support rail assigned to it.

Generally, the spring sections are preferably operable starting from the operating state by removing the respective spring section from the respective support rail to release the scratch spring from the respective support rail. It should be noted that in one embodiment, the scratch spring only rests against the respective support rail with one of the spring sections, so that releasing this spring section from the support rail leads to the scratch spring being released from the support rail. By actuating the scratch spring, the scratch spring is preferably released even further. further deflected from the rest position than it already is in the operating state, so that the spring force generated by the respective spring section must be overcome in order to release the respective spring section from the respective support rail. Particularly preferably, the spring sections can each be actuated as explained starting from the operating state, while the scratch spring remains unchanged with its fastening section fixed to the coupling body. This can achieve both a loss protection and a particularly robust design and multiple usability of the coupling. Generally preferably, the spring sections are designed to be actuated independently of one another, in particular each starting from the operating state by removing the respective spring section from the respective support rail to release the scratch spring from the respective support rail, while the scratch spring remains unchanged with its fastening section fixed to the coupling body.

In one embodiment, the scratch spring has a fastening section outside the spring sections, from which the spring sections extend, wherein a position of the fastening section relative to the coupling body is defined in all three spatial directions by a positive connection acting in all three spatial directions. The fastening section is thus specifically designed to ensure a fixed positioning of the scratch spring on the coupling body in all three spatial directions, regardless of the spring force required to press the spring sections against the support rails. Preferably, only the spring sections form the spring force with which they press against the support rails. Preferably, the fastening section experiences a deformation of the scratch spring starting from their rest position up to the deflection in the operating state, there is no deformation, so that the deflection is ensured almost solely by the deformation of the spring sections. The positive locking acting in three spatial directions determines the position of the fastening section in three spatial directions relative to the coupling body. Such a positive locking can be ensured, for example, by providing two stops in each spatial direction, whereby the fastening section can only move between these two stops in the respective spatial direction, so that there is a positive locking in this spatial direction, which limits the position of the fastening section in this spatial direction. The position of the fastening section is particularly preferably limited to a play of less than 3 mm, in particular less than 2 mm, in particular less than 1 mm, in particular less than 0.5 mm in at least two spatial directions, in particular in all three spatial directions. The three spatial directions are perpendicular to one another and thus generally span the space. In one embodiment, the three spatial directions correspond to the longitudinal direction, vertical direction and transverse direction explained. The inventors have found that the form-fitting action in three spatial directions ensures that the scratch spring is fixed to the coupling body in a particularly simple and space-saving manner, so that the scratch spring exerts a precisely controllable and reliable spring force for pressing against the support rails when the system is in the operating state. Generally, the fastening section preferably rests against the coupling body over at least 50% of its extension within one plane. This allows the fastening section to be particularly advantageously attached to the Coupling body can be supported. The plane particularly preferably runs perpendicular to the transverse direction or perpendicular to the vertical direction. The contact particularly preferably ensures a positive connection in a positive direction along a direction that runs perpendicular to the plane, whereas a positive connection in a negative direction along the direction that runs perpendicular to this plane is provided by a fastening means. Generally preferably, the fastening section is designed over at least a predominant part of its total extent in the manner of a plate, which extends flatly with its plate surface along an extension plane. The extension plane preferably corresponds to the plane explained above. Generally preferably, the extension plane runs perpendicular to the vertical direction or perpendicular to the transverse direction. In one embodiment, the spring sections perpendicular to the extension plane have an extension length that is at least twice as long as the fastening section in its part designed in the manner of a plate. In one embodiment, the spring sections are designed in the manner of a leaf, the leaf surface of which runs perpendicular to the extension plane. The spring sections can thus each be designed as a leaf spring, the leaf surface of which runs perpendicular to the extension plane. Preferably, the blade is designed as a curved blade. Preferably, when at least a predominant part of the fastening section is designed in the manner of a plate, the plate is designed with its plate surface extending essentially in one plane.

In one embodiment, the fastening portion forms a channel that extends along a channel direction and has an open side. The open side thus forms an end of the channel that delimits the channel in a direction that runs perpendicular to the channel direction. The channel has a channel base opposite the open side, which preferably runs continuously closed or has spaced-apart recesses, as well as channel side walls that extend from the channel base to the open side. The open side of the channel is closed at least in sections over its extension along the channel direction by a section of the coupling body, in particular by a section of one of the coupling side walls or the coupling base, wherein the channel and the section of the coupling body at least partially form the guide. In the embodiment according to the invention, the guide is thus at least partially formed jointly by the fastening section and the aforementioned section of the coupling body. This allows a particularly simple arrangement of the disassembly tool in the guide when producing the coupling in such a way that the disassembly tool is held captively on the coupling body. Particularly preferably, the channel direction runs straight, i.e. linearly, so that the channel together with the section of the coupling body enclose a hollow space extending in a cylinder-like manner along the channel direction. This is particularly advantageous for a linear guide of the disassembly tool and thus for setting the displacement path to a linear path, i.e. a straight path. Particularly preferably, the displacement path ends are defined by the ends of the channel that limit the channel in the channel direction. Particularly preferably, the disassembly tool extends with a guide section that connects two tool sections of the disassembly tool to one another within the Channel, wherein the guide section has a cross-section perpendicular to the channel direction, which is smaller than the cross-section of the two tool sections, so that the disassembly tool can be displaced along the channel direction relative to the coupling until one of the tool sections rests against one end of the channel. The channel ends can thus preferably form stops for the tool sections, defining the displacement path ends.

In one embodiment, the scratch spring is arranged on one of the coupling side walls, the system having a further scratch spring which has a first and second spring section, and a further disassembly tool. The further scratch spring is arranged on the other coupling side wall. For example, the scratch spring is arranged on the first coupling side wall and the further scratch spring on the second coupling side wall. In the operating state, the further scratch spring presses with its first spring section against the first support rail and with its second spring section against the second support rail. Preferably, the coupling has a further guide in which the further disassembly tool is arranged in a displaceable manner, wherein the further disassembly tool is mounted in the further guide and is displaceable between a first position and a second position on a displacement path determined by the further guide, wherein the further disassembly tool is arranged in the first position in the operating state and is arranged in the second position in a release state of the system and is pressed against the further scratching spring in the second position with deflection of the further scratching spring in such a way that the scratching nose of its second spring section is spaced from the second support rail.

The additional scratch spring and the additional disassembly tool as well as the additional guide and the corresponding design of the coupling body can, in advantageous embodiments, have features that are disclosed in connection with the scratch spring described in detail or the disassembly tool described in detail or the guide described in detail. Particularly preferably, the scratch spring and additional scratch spring are identically designed and/or the disassembly tool and additional disassembly tool are identically designed and/or the guide and additional guide are identically designed. Particularly preferably, the disassembly tool and the additional disassembly tool are designed as separate components and can be moved independently of one another. The provision of a scratch spring and additional scratch spring can be particularly advantageous for reliably fixing the support rails in the operating state, since an arrangement of the two scratch springs on the two coupling side walls can ensure the most uniform possible fixation. Particularly preferably, the scratch spring and additional scratch spring can be deflected independently of one another. Particularly preferably, the disassembly tool and additional disassembly tool and/or the scratch spring and additional scratch spring are manufactured independently of one another. Because the scraper springs are arranged on each of the clutch side walls, they can be operated particularly easily. Because the two can be operated independently of each other, they can be operated particularly easily and precisely.

In one embodiment, the disassembly tool can be operated by hand from the operating state to reach the release state. The disassembly tool particularly preferably has an actuating section that is adapted to the contour of a finger. The Disassembly tool operable by hand with a force exerted by the hand which is less than 20 N, in particular less than 10 N, in particular less than 5 N, wherein this force exerted by the hand is sufficient to bring the disassembly tool from the first position to the second position.

In one embodiment, the disassembly tool has a guide section that is arranged between the first and the second tool section and that is slidably mounted in the guide. The guide section preferably has a cross section perpendicular to the displacement direction, along which the displacement path extends, which is designed to correspond to the cross section of the guide perpendicular to the displacement direction. The guide section of the disassembly tool preferably has a smaller cross section along its extension between the tool sections than the tool sections. The direction along which the guide section extends preferably corresponds to the displacement direction along which the displacement path extends. The guide section particularly preferably has a constant cross section, so that the guide section has a constant cross section along its extension, in particular along the displacement direction, at least over at least 50%, in particular at least 70%, in particular at least 90% of its extension between the two tool sections.

In one embodiment, the tool sections are spaced apart from one another in the longitudinal direction. The tool sections particularly preferably have the same contour. The respective sections of the tool sections with which they are each connected to the each associated spring section are designed identically. Particularly preferably, the respective sections of the tool sections with which they can be manually operated, ie preferably the actuating section of the respective tool section explained here, are designed identically. Particularly preferably, their respective sections with which they can be locked to the coupling body are designed identically. Generally preferably, the locking device of the disassembly tool has two partial locking devices, each of the tool sections having one of the partial locking devices. Particularly preferably, the partial locking devices each comprise at least one projection. The partial locking devices can thus function as the sections with which the tool sections can be locked to the coupling body.

In one embodiment, the disassembly tool has a contact section by means of which the disassembly tool is supported on the coupling body or on the scratch spring in the release state for deflecting the second spring section. The contact section can preferably be designed as a projection. The contact section can preferably be the section on which the disassembly tool is pressed against the coupling in the second or third position when, as explained above, the disassembly tool is pressed between the said section of the coupling and the first or second spring section and this pressing applies a force required to maintain the respective deflection of the scratch spring in the release state.

The installation section can be one of the sections of the respective tool section explained above. Preferably each of the tool sections has such a contact section. In one embodiment, the contact section rests at least partially in the operating state and in the release state on a rotation axis formed by the coupling body or the scratching spring. The displacement path is preferably provided such that, as explained above, it runs in the manner of a section of a circular path around an axis running perpendicular to the longitudinal direction. In one embodiment, the contact section is designed and provided on the disassembly tool or the respective tool section such that during a displacement of the disassembly tool in the guide along at least a section of the displacement path, wherein the displacement means a movement between the first and second position and in particular between the first and third position, it slides outside the guide on a contact area formed by the coupling body or the scratching spring. As the contact section slides along the contact area during the displacement of the disassembly tool along the displacement path, a pressing force can be easily exerted by the respective tool section on the respective spring section during the displacement in order to deflect it so that it detaches itself from the associated support rail with its scratching nose. The contact area of the coupling body is particularly preferably provided as a section, in particular a projection, formed in one of the coupling side walls or in the coupling base.

In one embodiment, the disassembly tool and the guide are designed to correspond to one another in such a way that the disassembly tool, when displaced along the displacement path starting from the first position elastically deformed up to the second position. The elastic deformation can enable a particularly targeted application of the pressing force to the respective spring section. During this displacement, the contact section is particularly preferably moved in a first direction, whereas the section resting on the spring section is moved in a second direction that is angled to the first. The contact section and the section resting on the spring section each refer to a section of the disassembly tool assigned to a specific spring section. For example, the contact section and the section resting on the first spring section can be the first tool section of the disassembly tool, or the contact section and the section resting on the second spring section can be the second tool section of the disassembly tool. The angled arrangement of the two directions allows a force to be applied to the disassembly tool in a preferred direction, which can in particular be easily applied by one hand, whereas force can be applied to the spring section in a targeted manner in another direction.

As a further solution, the invention proposes a method for releasing the second support rail of a system according to the invention from the first support rail. In the method according to the invention, the disassembly tool is moved from the first position, in particular along the displacement path defined by the preferably provided guide, into the second position. The disassembly tool is particularly preferably locked to the coupling body in the second position. The second support rail is then removed from the first support rail, by moving the second support rail in the longitudinal direction relative to the first support rail, while the coupling and the disassembly tool remain fixed to the first support rail. In one embodiment of the method, a further disassembly tool is brought from its first position along a displacement path of a guide assigned to it into its second position and in particular is locked with the coupling body in the second position before the second support rail is removed from the first support rail. In one embodiment, the disassembly tool and the further disassembly tool are brought from the first to the second position simultaneously, in another embodiment one after the other.

The invention further relates to a luminaire which is manufactured by means of a system according to the invention. The luminaire is manufactured by bringing the system into its operating state. The luminaire preferably comprises at least two support rails which are fixed to one another in a fixed position by a coupling. The support rails each face one another with one of their longitudinal ends and are arranged with these longitudinal ends next to one another, in particular directly next to one another. The luminaire preferably comprises a plurality of mounting bodies which are fixed to the support rails of the luminaire and close the open side of the support rails over their longitudinal extent. The luminaire preferably comprises the disassembly tool, wherein the disassembly tool is held fixed to the coupling, in particular within an interior space enclosed by the support rails and in particular at least one of the mounting bodies. Furthermore, a first current conducting rail is preferably arranged in the first support rail and a second current conducting rail is arranged in the second support rail, wherein the lighting means of the mounting bodies which are in the respective are arranged on a support rail, are electrically connected to the current conducting rail, which is arranged in the respective support rail, via a contact device which is arranged in the respective support rail.

As a further solution, the invention proposes a coupling of a system according to the invention. As a further solution, the invention proposes an arrangement comprising a coupling of a system according to the invention and a disassembly tool of a system according to the invention. Preferably, the disassembly tool is fixed to the coupling in a captive manner and can only be moved relative to the coupling along a displacement path defined by the coupling between displacement path ends defined by the coupling, wherein the fixation or displaceability of the disassembly tool can be ensured by the guide described in connection with embodiments of the system according to the invention with the properties explained accordingly.

The various solutions according to the invention and their embodiments can each have features in embodiments that are disclosed here in connection with a different solution according to the invention. Furthermore, all of the embodiments described here can each be advantageously combined with one another with their features.

In Figure 1 comprehensively the Figures 1a and 1b is a inventive arrangement of lighting assemblies is shown. Such an inventive arrangement of lighting assemblies can be realized by the components of a system according to the invention. The Figure 1a The arrangement shown comprises a first support rail 1 and a second support rail 2 as well as a coupling 3. The coupling 3 has a coupling body 4 and a scratch spring 5. The scratch spring 5 has a first spring section 51 and a second spring section 52.

The coupling body 4 has, generally advantageous according to the invention, a first opening through which the first spring section 51 extends, and a second opening through which the second spring section 52 extends. The spring sections 51, 52 extend through the opening of the coupling body 4 assigned to them and rest on the support rail 1, 2 assigned to them. The first spring section 51 is pressed with a vertical spring force against a wall projection 111 of a support rail side wall of the first support rail 1 and the second spring section 52 is pressed against a wall projection 211 of a support rail side wall of the second support rail 2. The coupling body 4 also has a stop 441 against which the support rails 1, 2 each rest, which is generally advantageous according to the invention. The relative positioning of the support rails 1, 2 is determined by the resting on the stop. The stop 441 allows the coupling 3 to be easily inserted into the first support rail 1 until it rests against the stop 441, after which the second support rail 2 can be pushed onto the coupling 3 protruding from the first support rail 1 in the longitudinal direction X. The scratch spring 5 also has a fastening section 50, which in this case is designed in the manner of a plate. The fastening section 50 is secured by a fastening means 415 is fixed in position to the coupling body 4 with respect to the transverse direction Y. One of the side walls of the coupling body 4 and the fastening means 415 each form a positive connection with respect to the transverse direction Y, so that the fastening section 50 of the scratch spring 5 is fixed in its position with respect to the transverse direction Y between these two positive connections. In Figure 1b For illustration purposes, a view of the open ends of the support rails 1, 2 of the arrangement according to Figure 1a shown. From Figure 1b it can be seen that the coupling 3 extends from the first support rail side walls of the support rails 1, 2 to the second support rail side walls of the support rails 1, 2 and runs with its coupling base 40 along the support rail bases of the support rails 1, 2. The coupling 3 also has a centering section 31, 32 at each of its longitudinal ends, with which an insertion of the coupling 3 into the respective support rail 1, 2 is simplified, in particular a centering of the coupling 3 relative to other components that can be arranged in the support rail 1, 2, for example a centering with regard to an electrical connector and/or with regard to a current conducting rail that is arranged along the support rail base in the respective support rail 1, 2. From Figure 1b It can also be seen that two recesses 33, 34 are provided in the coupling base 40, which are designed for fastening components, for example an electrical connector. Figure 1b it can also be seen that pre-punches 400 are provided in the coupling base 40, which can be easily broken out of the coupling base 40 in order to enable a supply line to pass through these openings. In the support rails 1, 2, not shown here, a pre-punch aligned with this is provided, so that after breaking out the pre-punched holes provided in the coupling base 40 and the support rail bases, an electrical cable can be laid from outside the support rail base into the interior.

In Figure 2 comprehensively the Figures 2a and 2 B is the coupling 3 of the embodiment of the system, of which components are already in Figure 1 are shown schematically in various principle diagrams. From Figure 2a It can be seen in particular that the coupling 3 has a coupling body 4, which comprises a first coupling side wall 41 and a second coupling side wall 42 as well as a coupling base 40. In the coupling side walls 41, 42, two openings 420 are provided, through which one of the spring sections 51, 52 penetrates in each case so that it can be attached to the associated wall projection 111, 211, as in Figure 1a shown, the associated mounting rail 1, 2 can be installed. In Figure 2b Components of the embodiment of the system according to the invention are shown in the assembled state of the system, in which the coupling 3 is inserted with a first longitudinal section into the first support rail 1, so that its first, in Figure 2b not visible, spring section 51 presses against the wall projection 111 of the first support rail 1 and thereby ensures a fixation of the coupling 3 relative to the support rail 1, whereas the second longitudinal section of the coupling 3 protrudes beyond the first support rail 1. Accordingly, starting from the Figure 2b To achieve the operating state, the second support rail 2 is mounted on the Figure 2b The coupling 3 shown in the drawing can be pushed longitudinally until it comes into contact with the first support rail 1, whereby during this pushing on the second spring section 52 with its scratching nose 520 presses against the Wall projection 211 of the second support rail 2 presses and scratches, so that the second support rail is fixed in position relative to the first support rail in the longitudinal direction by means of the coupling 3.

In Figure 3 comprehensively the Figures 3a and 3b and in Figure 4 comprehensively the Figures 4a and 4b The functionality of the scratch spring 5 in conjunction with the disassembly tool 6 is shown in schematic diagrams. In Figure 4 is a different perspective than in Figure 3 shown. In the Figures 3a and 4a The disassembly tool 6 is not shown for explanatory purposes, in the Figures 3b and 4b The disassembly tool 6 is shown. In Figure 5 comprehensively the Figures 5a and 5b the scratch spring 5 and the disassembly tool 6 are shown separately. The scratch spring 5 is in Figure 5a shown, the disassembly tool in Figure 5b . From the figures it can be seen that the scratching spring 5 has a fastening section 50 which is designed in the manner of a plate, which extends flatly with its plate surface along a plane of extension. It can also be seen that the scratching spring 5 has two spring sections 51, 52, each of which has a scratching nose 510, 520 with which it presses against one of the support rails 1, 2 in the operating state with a spring force generated by it. The spring sections 51, 52 are each designed in the manner of a leaf spring and are thus each designed in the manner of a leaf, the leaf surface of which runs perpendicular to the said plane of extension along which the fastening section extends with its plate surface. This is generally advantageous according to the invention. Furthermore, it is generally advantageous according to the invention that the spring sections 51, 52 are each bent around a bending axis assigned to them in such a way that their scratching noses 510, 520 each a distance in a direction perpendicular to the bending axis, in the present case in the vertical direction Z. This design ensures that, on the one hand, in the operating state, a sufficient spring force can be provided in a simple manner, with which the spring sections 51, 52 press against the respective support rail 1, 2 by means of their scratching noses 510, 520. On the other hand, it is also ensured that when the second support rail is moved from the operating state to remove the second support rail 2 from the first support rail 1 in the longitudinal direction X, the said distance increases because the respective spring section is bent open with respect to its bending axis. This design of the spring sections 51, 52 is generally advantageous according to the invention and means that an even greater force is opposed to a release of the support rails 1, 2 starting from the operating state. Figure 5a it can also be seen that the fastening section 50 has a hole 518 for a fastening means and alignment holes 517. Furthermore, the fastening section 50 has at its longitudinal ends, generally advantageous according to the invention, a structural section 516 of a fastening structure of the fastening section 50, designed as a recess. The coupling body 4 has a fastening structure corresponding to the fastening structure of the fastening section 50, in this case comprising two structural sections 416. The structural sections 416 are each formed by deformation of the sheet metal from which the coupling body 4 is made. In the operating state, the structural sections 416, which are designed as projections, are arranged in the structural sections 516, which are designed as a recess. The structural sections 516, 416 of fastening section 50 or coupling body 4 are spaced apart from one another in the longitudinal direction X, generally speaking, spaced apart from one another in a direction that is perpendicular to an extension direction with which the extension section of the fastening means 415 extends through the hole 518. It can also be seen that the alignment holes 517 of the fastening section 50 are arranged in alignment with alignment holes 417 of the coupling body 4, so that during the manufacture of the coupling 3, the scratch spring 5 with its fastening section 50 can be correctly aligned relative to the coupling body 4 in a simple manner by means of alignment bolts. It can also be seen that the spring sections 51 each penetrate through an opening 410 that is arranged in one of the coupling side walls and press against the first or second support rail 1, 2. It is also clear from Figure 4a It can be seen that, generally advantageous according to the invention, the coupling side walls each have a slot 418 running in the longitudinal direction, whereby a certain vertical deflectability of the coupling side wall 41 is provided, so that the coupling side wall 41 can be easily pressed into a guide which is formed by the support rails 1, 2, as will be explained below with reference to Figure 7 is explained in more detail.

The disassembly tool 6 has a first tool section 61 and a second tool section 62, which are connected to one another by a guide section and are spaced apart from one another in the longitudinal direction X. Each of the tool sections 61, 62 is assigned to one of the spring sections 51, 52 of the scratch spring 5. In the operating state, as in Figures 3b and 4b As shown, the disassembly tool 6 is guided in the guide of the coupling 3 and is guided along a guide 45 can be displaced along a predetermined displacement path in the longitudinal direction X relative to the coupling body 4. Each of the tool sections 61, 62 has an actuating section 610, 620, at which it can be actuated by hand, as well as a section 615, 625, with which it can be brought into contact with the spring section 51, 52 assigned to it, as well as a contact section 612, 622, by means of which the disassembly tool 6 can be supported on the coupling body 4 in order to exert a force on the spring section 51, 52 assigned to it, as well as a locking section 611, 621, with which it can be locked to a corresponding locking section of the coupling body 4 in order to be held in a position in which it deflects the respective spring section 51, 52 to such an extent that its scratching nose does not rest against the support rail assigned to it. The disassembly tool can thus be brought into a second position starting from the operating state in which it occupies a first position relative to the coupling body 4, in which it is locked with its locking section 611 with a corresponding locking section 1161 of the coupling body 4 and is supported with its contact section 612 on the coupling body 4 and is pressed with a section 625 against the spring section 51, whereby it deflects the latter to such an extent that it cannot be in contact with the associated support rail 1, 2. Figure 5c is a view of the coupling 3 with the disassembly tool 6 attached. In Figure 6 the disassembly tool is shown in its second position. By bringing the disassembly tool 6 into the second position, it can enable the coupling 3 to be released from one of the support rails 1, 2, since the spring section 51, 52 associated with this support rail 1, 2 can be released from the respective support rail 1, 2.

For explanatory purposes, Figure 7 also a cross-section by components of the described embodiment of the system according to the invention, which extends perpendicular to the longitudinal direction X. From Figure 7 it can be seen that the support rail 1 has a support rail base 10 and a first support rail side wall 11 as well as a second support rail side wall 12. The support rail side walls 11, 12 each form a fixing guide 413, 423 in which a respective coupling side wall 41, 42 associated with them is held pressed in the vertical direction Z. The support rail side walls each form a wall projection 111, 121 against which the respective associated scratch spring presses with its first spring section 51 in the operating state. Furthermore, the support rail side walls 11, 12 each form a holding projection 412, 422 to which a conventional mounting body can be attached with a conventional holding spring. In the Figure 7 In the state shown, the disassembly tool 6, which is assigned to the scratch spring 5 provided on the first coupling side wall 41, is in the second position, whereas the disassembly tool 6, which is assigned to the scratch spring 5 provided on the second coupling side wall 42, is in the first position. Accordingly, the scratch spring 5, which is arranged on the second coupling side wall 42, presses with its scratch nose 510 against the wall projection 121 of the second support rail side wall 12, whereas the scratch spring 5 arranged on the first coupling side wall 41 is spaced with its scratch nose 510 from the wall projection 111 of the first support rail side wall. The two disassembly tools 6 can thus be operated independently of one another. In a state in which both disassembly tools 6 are in the first position, the coupling 3 is reliably connected to the support rail 1, and press the scratching noses 510 of the two scratching springs 5 shown against the wall projections 111, 121 of the support rail side walls 11, 12. In a state in which the two disassembly tools 6 are in the second position, the scratching noses 510 of the scratching springs 5 are spaced apart from the support rail side walls 11, 12.

In the Figures 8 and 9 Further embodiments of a system according to the invention are shown, which differs from the previously explained embodiments essentially in the design of the disassembly tool.

In the embodiment according to Figure 8 The first tool section 82 and the second tool section 81 of the disassembly tool are designed as separate components. The separate design or formation of the two tool sections and thus the multi-part design of the disassembly tool is generally an embodiment according to the invention, whereas in a general alternative embodiment according to the invention the disassembly tool is a one-piece component in which the tool sections are thus optionally integrated. The tool sections 81, 82 each have a section 815, 825 which surrounds the respective associated spring section 51, 52. In the Figure 8 In the illustration shown, the respective spring section 51, 52 is covered by the respective associated section 815, 825 of the tool sections 81, 82. The tool sections 81, 82 are each rotatably mounted on a rotation axis 810, 820. Accordingly, the displacement path has a course in the manner of a circular arc section around the respective rotation axis 810, 820. The tool sections can simply be attached to their ends protruding in the longitudinal direction over the scratch spring 5 with a finger by a specialist and are thereby rotated about the axis of rotation 810, 820 and thereby lead to the corresponding deflection of the associated spring section 51, 52. Preferably, a locking device and corresponding locking mechanism, as explained in other embodiments, can be provided in order to fix a corresponding release state.

In the embodiment according to Figure 9 the disassembly tool 7 is designed as a disassembly tool that can be moved linearly in the vertical direction Z. Accordingly, the disassembly tool 7 is guided by a linear guide on the coupling 3. The disassembly tool 7 according to the embodiment according to Figure 9 is a one-piece component that has two sections 751, 752 that are intended to be brought into contact with the spring sections 51, 52 in order to deflect them from the operating state in order to reach the release state. The disassembly tool 7 is designed to correspond to the coupling 3 in such a way that when the disassembly tool 7 is actuated to deflect the scratch spring accordingly, both spring sections 51, 52 are always deflected simultaneously.
