Description

[0001] The invention relates to a signaling device, in particular an optical signaling device, for public and / or private traffic and / or transport. Furthermore, the invention relates to a signaling system, in particular an optical signaling system, for public and / or private traffic and / or transport.

[0002] Signal devices, especially for road and / or rail traffic, must be safe (visibility, audibility, robustness with low weight, environmental friendliness, etc.), durable, and energy-efficient. For signal devices that function as optical indicators (traffic lights, light signals, etc.), LED technology combines high visibility with the currently highest energy efficiency. Furthermore, LED technology results in a long service life and therefore low maintenance costs for these optical indicators.

[0003] Depending on the operating environment, problems can arise regarding the longevity of a signaling device. High UV exposure combined with subsequent mechanical stress on the device, such as that caused by intense sunlight and later by hail, sand, and / or vandalism, is particularly problematic. High UV exposure causes a conventional signaling device housing to become brittle, which then becomes susceptible to mechanical damage.

[0004] In particular, the polycarbonate used for the signal transmitter housing, which is preferred due to its high strength and toughness (robust signal transmitter housings with low weight and minimal material usage), does not conventionally offer particularly high UV resistance. Prolonged exposure to UV light causes the signal transmitter housing to become brittle, significantly impairing its mechanical properties. The UV light breaks down the polymer chains of the signal transmitter housing, leading to the degradation of the polycarbonate material. Therefore, an object of the invention is to provide an improved, and especially a more durable, signal transmitter.

[0005] The object of the invention is achieved by means of a signal transmitter, in particular an optical signal transmitter (traffic light, light signal transmitter, etc.), for public and / or private traffic and / or transport; and by means of a signaling system, in particular an optical signaling system (traffic light system, light signal system, etc.), for public and / or private traffic and / or transport. Advantageous further developments, additional features and / or advantages of the invention will become apparent from the dependent claims and / or the following description.

[0006] The signal generator according to the invention comprises an actual signal generator with a signal generator housing, wherein the signal generator housing includes at least one electrical component of the actual signal generator. Preferably, the actual signal generator has a mechanical cover on the outside of a rear wall of its signal generator housing on a rear side opposite its signal output side and is designed as a double wall there.

[0007] The mechanical cover according to the invention can indirectly and significantly improve the UV resistance of the signal transmitter housing, so that even after prolonged exposure to sunlight, the signal transmitter housing largely retains its material properties. Through a specific design, appropriate positioning on / over the rear wall of the signal transmitter housing, and / or a suitable wall thickness of the mechanical cover, at least weather-related environmental influences can be very well and permanently resisted.

[0008] Previously, if a traffic signal head was damaged, it had to be replaced entirely. Replacing the mechanical cover is now sufficient, and this can be done quickly and easily. The previously time-consuming cleaning of the back of a traffic signal head (due to time-consuming and environmental soiling, stickers, lettering, etc.) can now be significantly simplified by removing the mechanical cover. This can prevent lengthy lane closures.

[0009] Furthermore, a functional separation can be implemented, whereby the signal transmitter housing is designed for the function of the actual signal transmitter, and the mechanical cover is designed for the protection of the actual signal transmitter. This results in lower acquisition and storage costs, as only the mechanical covers, and no longer the entire signal transmitters, need to be kept in stock for replacements. The mechanical cover is easy to install, easy to remove, and easy to replace (see below).

[0010] Furthermore, the mechanical cover can be easily colored (colored plastic granules used in the manufacturing of the mechanical cover (thus preventing weakening from coloring the signal housing), or a colored layer or film applied to the mechanical cover), which meets the needs of cities for the individual design of their signal heads. This also results in reduced logistical effort and costs for the procurement of raw materials, as well as significantly reduced production and storage costs, since a single base color, such as black, is sufficient for all actual signal heads of all signal head types.

[0011] The signal transmitter can be designed such that its mechanical cover can be mounted to the rear panel by means of a rotary and / or translational mounting movement. Alternatively, the mechanical cover can be mounted to the rear panel by means of a snap-in or click-in mounting mechanism. That is, the mechanical cover can be attached to the rear panel. For mounting the mechanical cover, it can first be positioned on one long side of the rear panel and then mounted on the other long side. Disassembly of the mechanical cover can be carried out in reverse order. This allows for easy cleaning, replacement, retrofitting, etc. of the mechanical cover (see above).

[0012] The actual signal transmitter can be designed such that the mechanical cover can be mounted to the transmitter housing without any additional assembly effort, while removing the mechanical cover from the transmitter housing requires additional disassembly. Alternatively, the mechanical cover can be mounted to the rear of the transmitter housing using a plug-in mechanism, requiring no additional assembly effort, while removing the mechanical cover from the rear requires manipulating the transmitter housing. The signal transmitter can, for example, be designed so that the mechanical cover can be easily mounted to the rear of a transmitter already mounted on a base. This also means, of course, that no other parts of the signal transmitter need to be disassembled and reassembled.

[0013] The signal transmitter housing can include a housing door that is pivotably mounted on a housing tray. The mechanical cover can be mounted on the rear wall of the housing tray when the housing door is closed and / or open, and / or removable from the rear wall. Alternatively, the mechanical cover can be mounted on the rear wall of the housing tray when the housing door is closed and only removable when the housing door is open. Of course, it is also possible to mount the mechanical cover when the housing door is open.

[0014] In one mounting position of the mechanical cover on the rear wall, at least the free, especially vertical, longitudinal ends of the mechanical cover can be essentially inaccessible from the outside by the housing door. This means that the mechanical cover cannot be removed when the housing door is closed; the housing door thus secures the mechanical cover to the rear wall. The mounting of the mechanical cover to the housing tray is secured by the mounted and closed housing door. However, this is not the case when the housing door is mounted and open; in this case, the mounting of the mechanical cover is disengaged and can be opened.

[0015] The mechanical cover can have multiple locking devices at its free, particularly vertical, longitudinal ends for mounting it to the housing. Such a locking device can be designed as a locking hook, a snap hook, etc. The locking devices are preferably located at the same height, e.g., vertically, with respect to a center line of the longitudinal ends, and preferably two, three, four, five, or more locking devices are provided per side and per signal transmitter module (see below).

[0016] The housing tray can only have a smooth section for the engagement of the mechanical cover's locking mechanisms. For example, the mechanical cover can be secured vertically against the rear wall by means of at least one stop between a locking mechanism and a hinge on the housing tray. Of course, it is also possible to use a different section of the housing tray for this purpose, such as a projection or a tab.

[0017] An air cushion or air slot can be provided between the back wall and the mechanical cover. In the event of mechanical stress on the cover, for example from hail or vandalism, an air cushion provides sufficient space to prevent the mechanical cover from impacting the back wall with such force that it could be damaged. An air slot can perform a similar function, particularly if it is not in fluid communication with the surrounding environment or if the flow is only fluid-throttled.

[0018] The mechanical cover can be arc-shaped with a curvature smaller than, equal to, or greater than the curvature of the rear wall. The mechanical cover can be mechanically pre-tensioned and mounted to the rear wall, or it can be mounted in this way. The mechanical pre-tension preferably acts radially outwards, thus pushing the mechanical cover away from the housing. The mechanical cover can be formed as a preferably wall-shaped, single-piece or integral mechanical cover. This applies, of course, to a mechanical cover for an entire signal transmitter or a signal transmitter module.

[0019] The mechanical cover can be made of plastic, in particular a UV-resistant plastic, or aluminum. Depending on the application and / or maintenance or cleaning intervals of the signal transmitter, it is also possible to manufacture the mechanical cover from a non-UV-resistant plastic. The housing door and / or the housing tray can each be made of plastic, in particular polycarbonate, or aluminum. The housing door and / or the housing tray can each be designed as a single piece, made from a single material, or integrally.

[0020] The actual signal transmitter can be designed such that the housing door can be opened / closed on two sides of the transmitter relative to the housing tray. This means that the housing door can be opened and closed, or closed and opened, on different sides of the housing tray. Furthermore, this means that the housing door can be opened clockwise and closed counterclockwise on one side, and opened counterclockwise and closed clockwise on the other.

[0021] Between the housing door and the housing base, two pivot joints, each with at least two pivots, can be arranged. That is, at least four pivots are arranged between the housing door and the housing base, of which at least two belong to each pivot joint. These at least two pivots form a pivot axis of the housing door on the housing base. Each pivot joint can form both a pivot axis and a locking mechanism of the housing door on the housing base.

[0022] A single pivot joint can comprise a hinge device for the housing door and a hinge device for the housing tub. One hinge device can have a spring-loaded joint, in particular a spring-loaded pivot pin. The other hinge device can have a relatively stationary joint, in particular a joint recess. This can, of course, be implemented in reverse depending on the climate.

[0023] The spring-loaded hinge device can have a spring-loaded tab and a pin (spring-loaded hinge pin) arranged at its free longitudinal end section. The pin can have a chamfer on its front section, which faces away from or opposite the actual housing shell or housing door. The hinge recess can have an edge on its front section, which faces away from the actual housing door or housing shell.

[0024] The angled surface on the pin and the opposite edge of the joint recess allow the pin to be lifted relative to the edge. In this process, the pin moves relative to the edge, or vice versa. Once the pin has moved far enough past the edge towards the joint recess, the spring-loaded design of its pre-tensioned tab causes the pin to snap into place.

[0025] The housing door preferably has a centrally located signal insert recess in which a signal insert, preferably electrical, can be installed or is already installed. The signal insert recess is preferably located centrally in the housing door. Locking devices can be provided on the signal insert recess by means of which the signal insert can be held or is held in place within the recess. This allows for easy installation and replacement of a signal insert without an additional part, resulting in less plastic waste.

[0026] The locking devices on the signal insert recess can be designed as spring-loaded snap hooks, which spring in automatically when the signal insert is inserted into the recess and snap back automatically when the signal insert is in the inserted position. Preferably, the snap hooks snap back essentially to their initial position.

[0027] An interface wall of the housing tray can have a through-hole internal thread. That is, the interface wall has a through-hole whose (inner) contour is formed as an internal thread. This eliminates the need for a flange nut. The housing tray can have at least one holder for a clamp and / or at least one cable retention slot on the inside. Furthermore, the housing tray can have internal reinforcing ribs. This allows the housing tray to be designed with thin walls, a thin design made possible by the UV protection provided by the mechanical cover.

[0028] The signal transmitter can have a modular design. In this case, a signal transmitter module can have exactly one (module) housing tray, exactly one (module) housing door, and exactly one mechanical (module) cover. This means that the above statements apply not only to an entire signal transmitter but also to at least one signal transmitter module of a signal transmitter.

[0029] Once the housing door (including the signal insert) is inserted into the housing tray, a signal transmitter module is created. This module can be mounted to at least one other signal transmitter module via at least one interface wall to form a customized signal transmitter. Advantages of this modular design include easy scalability of signal transmitters and an overall reduction in weight. Apart from the signal inserts, the signal transmitter modules of the signal transmitter can be essentially identical.

[0030] An interface wall of the signal transmitter module can have a through-hole (a through-cut), and an interface wall opposite this can have a through-cut. This means that a collar screw can be inserted through the through-cut of an interface wall of a first signal transmitter module and screwed into an internal thread of an adjacent interface wall of a second signal transmitter module. This allows two signal transmitter modules to be fixed together, with the sides of the opposing interface walls potentially featuring additional locking devices (positive locking elements, serrations, detents, detents, etc.) for alignment and / or preventing rotation of the two signal transmitter modules. To improve application flexibility, the through-cut of the opposite interface wall can also have an internal thread.

[0031] The signaling system according to the invention comprises an installation base and a signal transmitter that can be mounted thereon or is already mounted thereon, the signal transmitter being designed according to the invention. The signal transmitter or the signaling system is suitable, for example, for signaling vehicles (motor vehicles, rail vehicles, watercraft and / or aircraft), cyclists, pedestrians, etc. Furthermore, the signal transmitter or the signaling system is not only suitable for public and / or private traffic and / or transport, but can also be used in other ways, e.g., in sports.

[0032] The invention is explained in more detail below with reference to exemplary embodiments and the accompanying schematic drawing, which is not to scale. Sections, elements, components, units, and / or schemes that have an identical, univocal, or analogous design and / or function are identified by the same reference numerals in the description of the figures (su), the list of reference numerals, the claims, and in the figures (Fig.) of the drawing. A possible alternative not explained in the description of the invention (so), not shown in the drawing, and / or not exhaustive, a static and / or kinematic reversal, a combination, etc., of the exemplary embodiments of the invention or of a component, scheme, unit, component, element, or section thereof, can also be found in the list of reference numerals and / or the description of the figures.

[0033] In the invention, a feature (section, element, component, unit, function, size, etc.) can be positive, i.e., present, or negative, i.e., absent. In this specification (description (invention description (so), figure description (su)), list of reference numerals, claims, drawing), a negative feature is not explicitly described as a feature unless the invention specifically emphasizes its absence. That is, the actual invention, rather than one constructed by the prior art, consists of omitting this feature.

[0034] A feature of this specification can be applied not only in one specified manner, but also in another (isolation, summarization, replacement, addition, singularization, omission, etc.). In particular, it is possible, by means of a reference numeral and a feature associated with it, or vice versa, in the description, the list of reference numerals, the claims, and / or the drawing, to replace, add, or omit a feature in the claims and / or the description. Furthermore, this can be used to interpret and / or further specify a feature in a claim.

[0035] The features described can also be interpreted as optional features (given the (initially usually unknown) prior art); that is, each feature can be understood as optional, arbitrary, or preferred, i.e., as non-binding. Thus, it is possible to extract a feature, possibly including its periphery, from an embodiment, whereby this feature can then be transferred to a generalized inventive concept. The absence of a feature (negative feature) in an embodiment indicates that the feature may be optional (to a person skilled in the art) with respect to the invention. Furthermore, a generic term for a feature can also be inferred from a specific type of feature (possibly with further hierarchical subdivision into subgenres, etc.), which allows for a generalization of the feature, e.g., taking into account equivalence and / or similarity.

[0036] The figures in the drawing, which are merely exemplary and schematic, show: the Figs. 1 and 2 in perspective side views each an embodiment of a signal transmitter according to the invention for a signaling system according to the invention (only Fig. 2 ), the Figs. 3 and 4 in perspective views an embodiment of a signal transmitter module in a side view ( Fig. 3 ) as well as an open-fronted interior view ( Fig. 4 ), the Fig. 5 in a side perspective view a modularly constructed signal transmitter, the upper signal transmitter module of which is shown partially exploded, the Fig. 6 in a perspective side view an exploded view of an attachment assembly of components on / in a housing door for a signal transmitter module, which Fig. 7 in a perspective and side rear view an exploded view of an attachment assembly of an electrical signal insert on / in a housing door, and the Fig. 8In a side perspective view, an exploded view of an attachment assembly of a housing door to a housing tray or vice versa.

[0037] The invention is explained in more detail below with reference to exemplary embodiments of a signal transmitter 2 designed as a traffic light 2 or an optical signal transmitter 2 for a signaling system 0 designed as an optical signaling system 0. Of course, the invention is also applicable to other signal transmitters 2 and signaling systems 0. For example, the signal transmitter 2 can be designed as an acoustic signal transmitter 2, etc., and the signaling system 0 can be designed as an acoustic signaling system 0, etc. The signaling system 0 essentially comprises the signal transmitter 2 and an installation base 1 (see Figure 1). Fig. 2). The installation base 1 can be designed, for example, as a (traffic, whip, combination, etc.) mast, a supporting structure, a sign bridge, a fastening device e.g. on a bridge, a cable system, etc.

[0038] Although the invention is described and illustrated in more detail by preferred embodiments, it is not limited by these embodiments but is of a more fundamental nature. Other variations can be derived from these and / or from the above (invention description) without departing from the scope of protection of the invention. The invention is generally applicable in public and / or private traffic and / or transport, sports, etc.; that is, wherever signaling devices, in particular optical signaling devices 2, can be used.

[0039] The drawing only shows those spatial sections of an object of the invention that are necessary for understanding the invention. The explanation of the invention (see also above) with reference to the drawing refers, among other things, to a (bidirectionally non-directional) horizontal direction Hr, a (bidirectionally non-directional) longitudinal direction Lr, and a (bidirectionally non-directional) vertical direction Vr of the signaling system 0 or the signal transmitter 2 (see the Fig. 1, 2 and 5 A unidirectional direction as an optical signal direction Sr is essentially parallel to a horizontal plane and means, for example, the direction directed against flowing traffic in which a signal from the signal transmitter 2 propagates and against which the signal is visible.

[0040] The Figs. 1 and 2Figure 1 shows a signal transmitter 10 of a signal transmitter 2, as well as the signal transmitter 2 itself, wherein the signal transmitter 2 differs from the signal transmitter 10 by a mechanical cover 222, which, when mounted on the signal transmitter 10, transforms it into the signal transmitter 2. The signal transmitter 10, or signal transmitter 2, has a signal output side 11 and a rear side 12, wherein the signal direction Sr is essentially perpendicular to the signal output side 11 and is, for example, the direction Sr directed against flowing traffic. The side facing away from the signal output side 11 is accordingly the rear side 12.

[0041] The signal generator 2, and therefore also the actual signal generator 10, can be non-modular ( Fig. 1 ) or modular ( Fig. 2 , 3) be constructed. In the first case, the signal transmitter 2 has a preferably single housing tray 120, a single or a plurality of housing doors 110 (tray bottoms 110) and a preferably single mechanical cover 222. Here, the preferably single housing tray 120 and the single or plurality of housing doors 110 form a signal transmitter housing 110, 120 of the signal transmitter 2.

[0042] In the second case, the signal transmitter 2 has a plurality of signal transmitter modules 100, wherein a single signal transmitter module 100 has a single (module) housing tray 120, a single (module) housing door 110 (tray base 110), and a single mechanical (module) cover 222. Alternatively, a single mechanical cover 222 can be functional for a plurality of (module) housing trays 120 (not shown). In this case, the (module) housing trays 120 and the (module) housing doors 110 analogously form a signal transmitter housing 110, 120 of the signal transmitter 2.

[0043] For example, in the case of the Fig. 2 The traffic light 2 for motor vehicles shown has, apart from the color scheme of its signal inserts 102 (see below), three essentially identical signal modules 100 ( Fig. 3 ) analogous to the three display colors of a traffic light. - The following statements regarding a non-modular signal transmitter 2 and a modular signal transmitter 2 are interchangeable, apart from the modularity of an embodiment of a signal transmitter 2. - The following first describes the global assembly of the actual signal transmitter 10, with disassembly being carried out in reverse order.

[0044] The signal transmitter housing 110, 120 of the Fig. 1The housing tray 120 and at least one housing door 110 comprise at least one electrical signal insert 102, in particular an LED insert 102, is pre-mounted on / in the housing door 110 for the mounting of the signal transmitter housing 110, 120 (see below and the Figs. 5 to 7 The housing door 110 is inserted into the housing tray 120 and mounted thereon via a locking system (see below: two swivel joint devices 142, 152; 142, 152 - 142, 152; 142, 152). A door seal can be used to increase the ingress protection of the actual signal transmitter 10.

[0045] In the case of multiple signal transmitter modules 100 for the actual signal transmitter 10, a modular signal transmitter housing 110, 120 is created by connecting a single housing door 110 with a single housing tray 120. Such a modular signal transmitter housing 110, 120 can be connected to at least one other modular signal transmitter housing 110, 120 to form an individual actual signal transmitter 10 via at least one interface provided on it. For this purpose, the other modular signal transmitter housing 110, 120 naturally has an interface complementary to the first interface.

[0046] The shields 130 (phantom light shields) can be attached sequentially to the signal output side 11 of the signal transmitter housing 110, 120. Each shield can be connected to the (relevant) housing door 110 by means of a locking system. A locking system comprises a plurality of partially complementary locking devices on the relevant shield 130 and the housing door 110, in particular on an inner edge of its signal insert recess 112, cf. Fig. 6 The shields 130 serve to protect the individual signal inserts 102 from external light influences and increase signal detection and thus safety. - The following describes the assembly of individual components of the actual signal transmitter 10.

[0047] Assembly of the electrical signal insert 102, in particular the LED insert 102 (see Fig. 6 and 7The mounting of a signal insert 102 on / in a preferably central signal insert recess 112 of a housing door 110 is preferably carried out by means of four locking devices 113, in particular spring-loaded snap hooks 113 or clips, from a rear side towards the signal output side 11 of the housing door 110. The snap hooks 113 shown are shaped such that they compensate for a tolerance in the mounting direction. After mounting, the snap hooks 113 interlock in such a way that they can no longer release themselves (see also above).

[0048] Assembly of the housing door 110 (see Fig. 8The housing door 110 is mounted via a preferably two-sided locking system between the housing door 110 and the housing tray 120. Care must be taken to align the housing door 110 with the signal transmitter housing 110, 120. In the locked position, the locking system provides two pivot joints 142, 152; 142, 152 - 142, 152; 142, 152 between the housing door 110 and the housing tray 120, each with two pivot joints 142, 152; 142, 152, thus a total of four pivot joints 142, 152; 142, 152; 142, 152; 142, 152 with a total of eight joint devices 142, 142, 142, 142; 152, 152, 152, 152, 152.

[0049] In this arrangement, one joint device 142 is designed, in particular, as a pivot pin 143, 144, 145, and the other joint device 152 is designed, in particular, as a pivot recess 152. The joint device 142 can be designed, in particular, as a spring-loaded joint device 142 or, in particular, as a spring-loaded pivot pin 143, 144, 145. Furthermore, the joint device 152, in particular the pivot recess 152, can be relatively stationary. In the present case, the joint device 142 is mounted on the housing tub 120 and the joint device 152 on the housing door 110; however, this can also be reversed.

[0050] An externally accessible edge 155 is provided at the particularly relatively stationary joint recess 152, whereby the edge 155 may be designed in cross-section as a narrow projection; cf. Fig. 8, where an acute interior angle of a triangle characterizes the edge 155. This edge 155 preferably forms a periphery of the joint recess 152. - The particularly spring-loaded joint pin 143, 144, 145 preferably comprises a spring-loaded tab 143, from which a pin 144 projects substantially perpendicularly. The pin 144 can have a chamfer 145 mainly or substantially opposite the edge 155 at the joint recess 152.

[0051] During the assembly of the housing door 110 onto the housing tray 120, and also during the closing of the housing door 110 onto the housing tray 120, a bevel 145 meets an edge 145, whereby the bevel 145, and thus the corresponding pin 144, is lifted from the edge 155 and the pin 144 moves over the edge 155 towards the corresponding hinge recess 152. Once the pin 144 has moved far enough over the edge 155, it snaps into the hinge recess 152; the pin 144 is then mounted in the hinge recess 152.

[0052] The mounting of the housing door 110 to the housing tray 120 can be carried out such that all four pivot joints 142, 152; 142, 152; 142, 152; 142, 152 snap into place essentially simultaneously. Furthermore, during the mounting of the housing door 110 to the housing tray 120, two pivot joints 142, 152; 142, 152 on one side, particularly the vertical side, can initially snap into place, and subsequently the housing door 110, now pivotally connected to the housing tray 120, can be pivoted onto the housing tray 120, thus fully mounting the housing door 110 to the housing tray 120, the last step of which naturally also corresponds to closing the housing door 110 onto the housing tray 120.

[0053] To open the housing door 110 on the housing tray 120, the two pivot joints 142, 152; 142, 152 on one side, particularly the vertical side, can be released using a lever action (tool, such as a screwdriver) and the housing door 110 opened. To remove the housing door 110 from the housing tray 120, the two remaining pivot joints 142, 152; 142, 152 can be opened and then the housing door 110 removed from the housing tray 120.

[0054] Assembly of the signal transmitter modules 100 next to each other ( Figs. 3 and 4 ) - A collar screw and a tool are required for a mechanical connection of two signal transmitter modules 100 (both not shown). Before connecting, the signal insert(s) 102 must be wired through the collar screw and a through-hole 127 ( Fig. 4) for the collar screw in a particularly lower or upper, preferably horizontal interface wall 123 of a first signal transmitter module 100 from the inside.

[0055] Consequently, at least one cable must be routed through an internal thread 125 in a preferably upper or lower, and preferably horizontal, interface wall 121 of a second signal transmitter module 100. The internal thread 125 in the interface wall 121 is analogous to a flanged nut for a flanged screw. The internal thread 125 is preferably integrally formed in the interface wall 121 of the signal transmitter module 100.

[0056] The two signal transmitter modules 100 are now aligned, e.g., by means of detents, corresponding, e.g., partially complementary codings, etc., and connected using the tool by tightening the collar screw with the internal thread 125. Subsequently, the lower housing door 110 can be opened and the signal insert 102 or the signal inserts 120, 102, ... can be wired in the lower housing compartment 120.

[0057] Further assembly steps – Now the brackets of the actual signal transmitter 10 can be connected to the signal transmitter housing 110, 120. For this, the previously used tool and a collar screw are required. First, an output cable from the actual signal transmitter 10 is fed through the collar screw and the bracket. Then, the bracket can be screwed to the signal transmitter housing 110, 120 using the collar screw. Angle adjustment can be achieved, for example, by detents, corresponding (e.g., partially complementary) coding, etc.

[0058] The actual signal transmitter 10 is attached to the installation base 1, in particular a mast 1, for example by screwing the upper bracket in place with at least one screw and, for example, a band clamp for the lower bracket. Other forms of attachment are of course applicable. Subsequently, the guards 130 (preferably without additional tools, using in particular three clamping lugs on the inside of the signal insert recess 112) and preferably also the mechanical cover 222 for the actual signal transmitter 10 can be mounted.

[0059] The mechanical cover 222 ( Figs. 1 to 4 , see also above) - The actual signal transmitter 10 is designed such that the mechanical cover 222 can be mounted on its rear wall 122 ( Fig. 1 ) or mounted ( Fig. 2 ) is such that the resulting signal transmitter 2 has a double-walled rear wall 12 (advantages see above). Here, the Fig. 1a pre-assembly position V of the mechanical cover 222 on the rear wall 122 of the housing tray 120, and the Fig. 2 shows a mounting position M of the (module) covers 222 on the rear walls 122 of the (module) housing trays 120.

[0060] The actual signal transmitter 10 can be designed such that the mechanical cover 222 – whereby, of course, the modular design of the actual signal transmitter 10 is always evident – ​​can be easily mounted by hand onto the signal transmitter housing 110, 120. Furthermore, the actual signal transmitter 10 can be designed such that the mechanical cover 222 can either be easily removed by hand from the signal transmitter housing 110, 120, or it cannot be easily removed from the signal transmitter housing 110, 120.

[0061] D. hz B., that no tools are required for assembly and for the first case of disassembly, and / or no further disassembly step needs to be performed. For the second case of disassembly, a tool may be required, and / or a further disassembly step may be necessary. Such a further disassembly step could, in particular, be opening the housing door 110, thereby providing access for disassembly to at least one side of the fastening of the mechanical cover 222 to the housing tray 120.

[0062] For these embodiments, the mechanical cover 222 can be installed with the housing door 110 closed, open, or removed. However, for these embodiments, the mechanical cover 222 can only be removed with the housing door 110 open or removed. Other embodiments are, of course, applicable.

[0063] The mechanical cover 222 is adapted to a contour of the rear wall 122 of the housing tray 120 and has a plurality of locking devices 2222, in particular locking hooks 2222, snap hooks, etc., at its two free, in particular vertical, longitudinal ends 2220, 2220. The mechanical cover 222 can in particular be arc-shaped. Furthermore, the mechanical cover 222 can be spaced apart from the rear wall 122 in the signal transmitter 2 by means of an air cushion or an air slot.

[0064] In one embodiment, during the assembly of the mechanical cover 222, the locking devices 2222 of a single free longitudinal end 2220 are first hooked onto a free, in particular vertical, longitudinal end of the rear wall 122 or the housing tray 120. Subsequently, the locking devices 2222 of the other free longitudinal end 2220 can be pressed against the rear wall 122 or the housing tray 120. This causes the, for example, arc-shaped mechanical cover 222 to widen slightly in the horizontal direction, so that the other locking devices 2222 can engage or snap into place at the other free longitudinal end 2220 of the rear wall 122 or the housing tray 120.

[0065] To remove the mechanical cover 222, e.g., with the housing door 110 open, the locking devices 2222 of one free longitudinal end 2220 are released from the corresponding free longitudinal end of the rear wall 122 or the housing tray 120, e.g., using a flat screwdriver. The locking devices 2222 then fall off the other free longitudinal end of the rear wall 122 or the housing tray 120.

[0066] The illustrated housing trays 120 show, in addition to their open or partially open front (11) and their U-shaped rear wall 122 in cross-section (see the Figs. 3 and 4 ) no pronounced side walls. Such pronounced side walls can of course be present, whereby by means of the mechanical cover 220 none, additionally one or both side walls may also be covered.

[0067] Furthermore, additional components, such as a cover ring / mask ring, a contrast aperture, etc., can of course be mounted on / in the actual signal transmitter 10 or signal transmitter 2. Reference symbol list
