Description

The present invention relates to an emergency operating device for a vehicle, in particular a rail vehicle, with an actuating element for a control device and a shield associated with the actuating element, wherein the control device unlocks an access device, in particular a door to the vehicle upon actuation of the actuating element from a rest position, the Shield in a closed state shields the located in its rest position actuator against unobstructed access. It further relates to a vehicle having such an emergency operating device.

For public transport, in particular rail transport, there are a large number of specifications or standards which define the necessary characteristics of the vehicles used. Frequently, regulations regarding the safety of transported passengers play a central role. Thus, there are typically requirements that in the vehicle precautions must be taken that allow passengers to leave the vehicle quickly and safely in an emergency. For example, part of the "Technical Specification for Interoperability" (TSI) issued by the European Commission, namely the so-called TSI-RST, states that an emergency opener (internal emergency) for passenger-owned vehicle doors is independent of speed signaling and must be triggered by at least two consecutive actuations (see TSI-RST, Chapter 4.2.2.4.2.1 g).

In some known vehicles, for example the vehicles of the class ICE 1 of Deutsche Bahn AG, the problem was solved by means of an emergency operating device in which an actuating element in the form of an emergency handle (for manual door unlocking) is used in combination with an emergency switch. In normal operation, the emergency handle is mechanically decoupled from a shaft which triggers the door unlocking. In an emergency, the emergency grip is only by pressing the emergency switch (first operation in the sense of the TSI) coupled via an electromagnet with the shaft (the emergency handle thus "activated"). Only then is the door unlocking triggered by the actuation of the emergency handle (second operation in the sense of the TSI). Often, first of all, one has to first switch the emergency switch to be able to operate it (see ICE 1) so that even three consecutive operations in the sense of the TSI are required.

Although this solution has the advantage that it (at least in a variant without the emergency switch covering disc) could also be used for a regular local door unlocking, as required for example in the maintenance and cleaning of the vehicle by appropriate personnel. However, it has the disadvantage that it is relatively complicated and expensive due to the required (especially in emergency situations to be ensured) supply of the electromagnet with (not inconsiderable) performance.

In other known vehicles, such as the vehicles of the series "Sprinter Lighttrain" of the Dutch Railways AG, the problem was solved by means of a generic emergency operation, in which the emergency grip is behind a shield in the form of a disc. This disc is bolted to the vehicle via a frame and must first be hammered in (first actuation as defined by the TSI) and then the door unlocking can be triggered by actuation of the emergency handle (second actuation as defined in the TSI).

Although this solution has the advantage that it is simpler and more robust. The mandatory destruction of the disc, however, entails a certain risk of injury (which could indeed be eliminated by aids, such as an emergency hammer, which in turn means additional effort), on the other requires the compulsory destruction of the disc a comparatively complex exchange of the latter after their destruction ,

The present invention is therefore based on the object to provide an emergency control device or a rail vehicle of the type mentioned, which or which does not have the disadvantages mentioned above or at least to a lesser extent and in particular with a simple design, a compact and reliable device for local unlocking of access to the vehicle allows.

The present invention solves this problem starting from an emergency operating device according to the preamble of claim 1 by the features stated in the characterizing part of claim 1.

The present invention is based on the technical teaching that with a simple design, a compact and reliable means for local unlocking the access to the vehicle (ie, for example, of doors or possibly also windows) allows if the shield comprises a locking device, the simple in one short, one-time unlocking action, for example, in a single operation, with or without tools (such as keys or the like) can be unlocked so that the shield can be opened, after which then actuates the actuator for actuating the emergency release of the access device (ie the door, etc.) can be.

Compared to the known designs with an emergency switch (for "activation" of the actuating element), this design has the advantage that it can be designed purely mechanical, which considerably simplifies their production and maintenance.

Compared with the known designs with the firmly screwed, to be destroyed glass this design has the advantage that it reduces the risk of injury on the one hand can be dispensed by the glass. In the case of a shield with such a glass pane, but also (for example by cleaning personnel or the like) by unlocking a (possibly reversible) operation of the emergency release can be made without the glass pane must be destroyed.

According to one aspect, the present invention therefore relates to an emergency operating device for a vehicle, in particular a rail vehicle, with an actuating element for a control device and a shield associated with the actuating element, wherein the control device an access device, in particular a door to the vehicle as a result of actuation of the actuating element of a Rest position unlocked. The shield shields in a closed state the actuator located in its rest position against unobstructed access. The shield comprises a locking device, which can be brought into a unlocked state via a short, unique unlocking action, in particular a single handle, wherein the shield in the unlocked state of the locking device can be brought into an open state. The shield is in the open state of the actuator and thus releases the operation of the actuator.

The shield can basically be designed in any suitable manner, as long as it can be moved in the unlocked state of the locking device such that the actuating element is exposed for actuation. Thus, for example, be provided that the shield only in a corresponding holder (for example, in one or a plurality of retaining rails) is held and in the unlocked state of the locking device can be completely removed from the Notbetätigungsesnrichtung (eg withdrawn or lifted) can be. In preferred variants of the emergency operating device according to the invention, however, the shield is permanently attached to the emergency control device, so that it can not be lost even in the unlocked state of the locking device.

It is preferably provided that the shield is held by a holding element. Preferably, the shield is pivotally articulated on at least one pivot joint on the holding element, since this is a particularly easy-to-use design is achieved. Additionally or alternatively, the retaining element may be attached via at least one connecting means to a housing of the emergency operating device. In this case, it can then also be detachably fastened in order to facilitate its simple replacement.

The locking device can in principle be designed in any suitable manner in order to realize the desired simple and rapid unlocking (eg with a handle). In preferred variants of the emergency operating device according to the invention, the locking device comprises at least one easily destructible in the course of unlocking locking element which, for example, with a single handle (by applying a correspondingly high force and / or a jerky operation) shears, tears or tears. In particular, it can be a seal (for example a conventional wire seal).

The force for destroying the locking element can also be applied directly via the actuation or the opening of the shield (that is, its movement into its open state), so that no separate operation for unlocking and opening the shield is required. Hereby, a particularly rapid opening of the shield is possible in an advantageous manner.

This design also makes it possible to attach the locking element so that it can be destroyed (for example, thanks to appropriate leverage ratios) on the one hand with reasonable effort by any (possibly weaker persons). On the other hand, the force level required for the destruction can be adjusted so that inadvertent destruction is usually avoided.

In further variants of the invention it is additionally or alternatively provided that the locking device comprises at least one magnetic element, which the Shield holds without further external force in the closed state. Here, the magnetic element can also form at least a part of the shield itself.

With this design, on the one hand a disturbing noise by a loose cover can be reliably prevented. On the other hand, the force effect can be set by the magnetic element so large that it produces the complete locking of the cover. This design has the advantage that it allows opening and closing of the shield without further aids (whereby the height of the required actuating force prevents unintentional opening). The magnetic device also has the advantage that the force acts against the opening of the shield decreases with increasing opening of the shield, so that they do not interfere with the subsequent operation of the actuator. In particular, the magnetic element can then also be used in a simple manner to lock the shield in its open position.

If it is desired that the shield can not be closed unrecognized again, it can either be provided that the shield can no longer be moved into the closed position (at least without appropriate aids). Alternatively, although closing the shield may be allowed, opening (and / or closing) activates a marker (at least not resettable) indicating that the shield has been opened.

An effect similar to the effect of the magnetic element can additionally or alternatively be realized, for example, by otherwise biasing the shield against a stop, for example via a spring device or the like.

Further preferred embodiments of the emergency operating device according to the invention are characterized in that the shield is designed such that they are resistant to the effects of violence, and therefore withstand a human violence caused without aids. For this purpose, the shield may, for example, have a shielding element which shields the actuating element and is constructed from at least one metallic material and / or a plastic.

In further preferred embodiments of the emergency operating device according to the invention, the locking device comprises a simple lock device, via which the Shield is locked. The lock device can be easily released via a corresponding key element, so that the shield can be removed and the actuator (for example by authorized personnel for local access unlocking for cleaning or maintenance purposes) can be operated without destroying parts of the shield. This has the advantage that on the one hand a simple, robust and fail-safe solution without the need for a separate power supply is possible. On the other hand, a separate unlocking device for local access unlocking for authorized personnel omitted because this function (local access unlocking for cleaning or maintenance purposes) can be easily integrated into the emergency operation device.

According to a further aspect, the present invention relates to an emergency operating device for a vehicle, in particular a rail vehicle, with an actuating element for a control device and a shield associated with the actuating element, wherein the control device upon actuation of the actuating element from a rest position, an access device, in particular a door to Vehicle unlocked. The shield shields in a closed state the actuator located in its rest position against unobstructed access. For this purpose, the shield may, inter alia, have an easily destructible element which is assigned to the actuating element in the closed state of the shield in such a way that the actuating element is accessible for actuation after destroying the destructible element. The locking device comprises a lock device, wherein the lock device has a locked state in which the closed shield is locked in position by the lock device. The lock device is adjustable by means of an associated key element in an unlocked state in which the shield for releasing the actuation of the actuating element is removable from the actuating element.

In all the cases described above, the emergency operating device may be designed in such a way that upon return of the actuating element to its idle state, the access device locks again regardless of whether the previous operation in an emergency involves destruction of the shield (possibly partial) or in the context of a regular access unlocking (FIG. by authorized personnel) without destroying the shield. As a result, a particularly simple design can be achieved.

In further variants of the invention, a determination or registration of the circumstances of the operation and in dependence thereon a different treatment of the return of the actuating element takes place. Thus, it can be provided that it is detected via a corresponding sensor that the actuation of the actuator at non-destructive (opening the lock device) opened shield took place, and accordingly when resetting the actuator in its idle state, the access device (if it is properly closed) again locked become.

In a particularly simple variant of the invention, this detection of the circumstances of the operation takes place via the lock device. For this purpose, the lock device is signal-technically connectable to the control device, wherein the control device in the unlocked state of the lock device locks the access device again when the actuator is returned to its idle state.

The generation and transmission of the signals between the lock device and the control device can take place in any suitable manner. For example, mechanical, fluidic (i.e., pneumatic and / or hydraulic), electrical generation and transmission of the signals, as well as any combination thereof may be provided. In particular, in designs in which the locking of the access device already takes place on pneumatic, preferably also the signal transmission between the lock device and the control device takes place at least partially, preferably substantially completely, pneumatically. As a result, a particularly simple design without the use of additional energy sources is possible.

If the previous operation resulted in an emergency (possibly partial) destruction of the shield, it may be sufficient to open only the lock device (by authorized personnel) and, if appropriate, the shield to allow locking of the access device.

In other variants, but also a further or separate reset signal may be required for this purpose. For this purpose, the lock device can be connected, for example, with the control device signal technically, wherein the control device in the locked state of the lock device when resetting the actuator in its idle state, the access device only in the presence of an additional reset signal (which has been specified, for example by authorized personnel in a suitable way) locked.

The detection of the state of the lock device can take place in any suitable manner. Thus, the lock device actuate, for example, a corresponding switch or the like of the control device when actuated. The lock device preferably comprises a detection device that can be connected to the control device by signal technology, in particular a sensor device or a switch device, wherein the detection device detects the locked state and / or the unlocked state of the lock device and delivers a corresponding signal to the control device.

The lock device and the key element can be designed in any suitable manner which prevent a sufficiently rapid opening of the shield without a corresponding key element or special tool. Because of the still simple design is preferably provided that the key element is designed as a simple triangular element or as a square element.

The shield may be removable from the actuator in any suitable manner (with the latch mechanism unlocked). Preferably, the shield is designed as a pivotally hinged lid. This facilitates opening and closing by authorized personnel.

In preferred variants of the invention, the shield is constructed as a pivotably hinged lid about a first pivot axis and the actuating element is designed as a pivot lever which has a free first end and a second end, in the region of which the actuating element is articulated pivotably about a second pivot axis. The first pivot axis and the second pivot axis in this case run substantially parallel to one another and the free first end of the actuating element is arranged in its rest position closer to the first pivot axis than the second end. This is in terms of avoiding accidental unlocking advantage, since first the shield must be opened by a considerable angle (with opposite pivoting direction to the pivot lever) to even reach the pivot lever and operate.

The shield may be configured in any suitable manner. Thus, it may be formed as a one-piece or multi-part lid.

As mentioned, the shield may have an easily destructible element which is associated with the actuator in the closed state of the shield such that the actuator is accessible after destruction of the destructible element for actuation. In this case, the destructible element can be formed by a transparent pane, in particular a glass pane. This results in each case particularly simple designs.

The actuator may also be designed in any suitable manner which allows a passenger with normal force unlocking. Preferably, the actuating element is formed by a, in particular hinged at the end, pivot lever.

Furthermore, emergency control device may be attached to the vehicle in any suitable manner. Thus, their components can be mounted individually or in assemblies in the vehicle interior (but possibly also on the vehicle exterior). However, particularly easy to install designs are characterized in that the actuating element is arranged in a housing to which the shield is attached.

The present invention further relates to a vehicle, in particular a rail vehicle, with a car body having an access device, in particular a door or a window, and an emergency operating device according to the invention, wherein the emergency operating device is associated with the access device for actuating the access device. Hereby, the variants and advantages described above can be realized to the same extent, so that in this regard reference is made to the above statements.

First example

The following is with reference to the Figures 1 and 2 a first preferred embodiment of the rail vehicle 101 according to the invention described, which has a vehicle longitudinal axis 101.1 1. For ease of understanding of the following explanations, a vehicle coordinate system x, y, z is indicated in the figures, in which the x-coordinate, the longitudinal direction of the rail vehicle 101, the y-coordinate, the transverse direction of the rail vehicle 101 and the z-coordinate, the height direction of Rail vehicle 101 denote.

The FIG. 1 shows a schematic view of the rail vehicle 101. The vehicle 101 includes a car body 102 which is supported in the region of its two ends in each case on a chassis. The access to the interior of the car body 102 is inter alia via an access device in the form of a door 103. In the car body 102, a preferred variant of the emergency operating device 104 according to the invention is arranged, as prescribed for example in Europe by the aforementioned TSI.

The door 103 can be locally unlocked via the emergency operating device 104, in order to then open it by hand. On the one hand, this may be necessary if the passengers want to leave the vehicle 101 in an emergency. It may also be desirable that such local unlocking and manual door opening in the case of cleaning or maintenance of the vehicle 101 by a corresponding authorized personnel in a simple manner can be made.

In particular FIG. 2 can be seen, the emergency operation device 104 comprises an actuating element in the form of a pivot lever 105, by the actuation of the unlocking of the door 103 is triggered. The designed as a conventional emergency handle pivot lever 105 can this be touched on a handle 105.1 in the region of its free, first end and then to unlock the door 103 from his in FIG. 2 shown rest position to be pivoted about its pivot axis 105.2, to which he in Is pivotally hinged to a housing 106, which in turn is attached to the structure of the car body 102 in the vicinity of the door 103 of its second end.

The pivotal movement of the emergency handle 105 is detected by a suitable detection element 105.3 (for example, a switch, a valve or the like) and triggers a corresponding signal to a control device in the form of a door control 107, which causes the unlocking of the door 103.

The signal transmission from the emergency handle 105 to the control device 107 and further to the door 103 can take place in any suitable manner. Here, mechanical, electrical and fluidic principles of action can be used individually or in any combination. In the present example, a pneumatic actuation of the door 103 is provided so that a pneumatic action principle is also used in the respective signal transmission. This has the advantage that no additional energy source for the signal transmission is provided.

In order to avoid inadvertent or undesired operation of the emergency handle in accordance with the provisions of the aforementioned TSI, the emergency actuator 104 comprises a shield in the form of a lid 108 which, in a closed condition, shields the emergency handle 105 in its rest position against unimpeded access.

The cover 108 is pivoted about a pivot axis 108.1 to the housing 106 such that it is in his (in FIG. 2 shown) closed state covers the entire housing side facing it of the housing 106. At the end of the cover 108 facing away from the pivot axis 108.1, a first closing element 109.1 of a locking device in the form of a lock device 109 is arranged which, in the closed state of the cover 108, can cooperate with a second closing element 109.2 of the lock device 109 arranged on the housing 106, around the lid 108 in its closed state and thus to shield the emergency grip against unauthorized access.

For locking and unlocking the lock device 109, a key element (not shown) in the form of a simple square socket wrench is provided in the present example, which cooperates with the square profile of the first closing element 109.1 in order to bring the first closing element 109.1 and the second closing element 109.2 into engagement with one another to solve this intervention.

The lid 108 has an easily destructible element in the form of a glass pane 108.2, which is held in a frame 108.3 of the lid 108. In the closed state of the lid 108, the glass pane 108.2 is assigned to the emergency handle 105 in its rest position such that the emergency handle 105 can be pivoted out of its rest position in an emergency situation after destroying the glass pane 108.2 (first actuation within the meaning of the TSI) (second Acting within the meaning of the TSI) to trigger the unlocking of the door 103.

The above-described design of the emergency operating device 104 also makes it possible for suitably authorized personnel to unlock the lock device 109 using a corresponding key element and insert the cover 108 into the (in FIG FIG. 2 dashed line shown) pivoted open position in which the emergency handle 105 can be actuated to unlock the door 103 without destroying the glass 108.2.

For unlocking the lock device 109 only a short one-time unlocking action is necessary, namely a single handle. This makes it possible to use the emergency operating device 104 also for a regular local unlocking of the door 103, as it may be desired or required for purposes of maintenance and / or cleaning of the vehicle 101, for example. It is thus advantageously no longer necessary to provide a corresponding separate device for these purposes, the regular local unlocking.

In the present example, the (first) pivot axis 108.1 of the cover 108 and the (second) pivot axis 105.2 of the emergency handle 105 extend parallel to one another, so that their pivoting movements take place in a common plane. It is understood, however, that in other variants of the invention can also be provided that the two pivot planes transverse to each other, in particular perpendicular to each other. Such an arrangement of the pivot axes or pivot planes has the advantage that first the lid must be deliberately opened by a certain (depending on the position of the pivot planes different sizes) pivot angle before the emergency handle can be actuated, so that an erroneous operation is less likely. In the present example, this securing is achieved in that the handle 105.1 is arranged between the two pivot axes 108.1 and 105.2, so that opposing pivoting movements when opening the lid 108 or when operating the emergency handle 105 are required.

In the present example, the locking of the door 103 is actuated again when the emergency handle 105 has been pivoted back to its rest position. This can of course be provided that the controller 107 suitably checks whether the door 103 is again in its correct closed position, and only in this case, the lock of the door 103 is actuated.

However, it is understood that in other variants of the invention can also be provided that is taken into account when resetting the emergency handle 105, whether its operation is done in an emergency situation by destroying the glass 108.2 or in the context of a regular unlocking the door with the lid 108 open , as described below in connection with the second embodiment.

Second embodiment

The following is with reference to the Figures 1 and 2 A second preferred embodiment of the rail vehicle 101 according to the invention or the emergency operating device 104 according to the invention is described. The difference to the first embodiment is merely that the emergency operation device 104 has a further detection device, as in FIG. 2 indicated by the dashed contour 110.

On the basis of a signal transmitted by the detection device 110 or applied to the detection device 110, it is detected in the control device 107 whether the lock device 109 is in a locked state or in an unlocked state.

When the lock device 109 is in an unlocked state, it is assumed that it has been unlocked from an appropriately authorized side by a suitable key element. In this case, the door 103 is locked again upon return of the emergency handle 105 to its rest position.

If this is not the case, then the lock device 109 is in a locked state, it is assumed that the emergency handle 105 was operated in an emergency situation to destroy the glass sheet 108.2. In this case, the control device via a separate signal line 111, a separate reset signal must be specified to lock the door 103 when resetting the emergency handle 105 in its rest position.

However, it will be understood that to re-lock the door 103 it may also be sufficient for the lock device 109 to be brought into its unlocked state prior to the return of the emergency handle 105 in order to achieve the previously described signal constellation.

It is further understood that the detection means 110 may be configured in any suitable manner. Preferably, in the present example it also operates pneumatically (for example, via a simple pneumatic switch also actuated upon actuation of the lock device 109) to obviate the need for an additional source of energy.

Third embodiment

The following is with reference to the FIGS. 1 . 3 and 4 a third preferred embodiment of the rail vehicle 101 according to the invention or the emergency control device 204 according to the invention described which can be used instead of the emergency operation device 104 in the rail vehicle 101. The emergency operating device 204 corresponds in its basic design and operation of the emergency operating device 104, so that only the differences should be discussed here. In particular, similar components are provided with increased by the value 100 reference numerals. Unless otherwise stated below, reference is explicitly made to the above statements with regard to the features of these components.

The difference to the first embodiment consists essentially only in the design of the shield 208. Like the FIGS. 3 and 4 can be seen, the shield 208 in turn comprises a cover 208.4, which in an in FIG. 3 shown closed state shields the emergency handle 105 located in its rest position against unobstructed access.

For this purpose, the cover 208.4 is pivotably connected to a holding element 208.5 about a pivot axis 208.1. The holding element 208.5 is in turn attached to the housing 206 of the emergency actuator 204. The dimensions are chosen so that the cover 208.4 is pivotally hinged to the housing 206 of the emergency actuator 204, that he in his (in FIG. 3 illustrated) closed a sufficiently large part of the housing side facing him the housing 206 to cover the handle portion 105.1 of the emergency lever 105 and thus shield against unobstructed access.

To lock the shield 208 in its closed state, a locking element (not shown) in the form of a simple wire seal 209 is provided in the present example, whose sealing wire 209.1 is guided through a bore 208.6 in the cover 208.4 and an associated bore in the emergency lever 105. The ends of the Plombierdrahts 209.1 are then sealed in a conventional manner by means of a seal 209.2.

In the present example, the lid 208.4 is formed as a simple non-destructible element by normal human action without tools (such as tools or the like). In the present example it is designed as a simple, flat element made of sheet steel with a protective coating. It is understood, however, that in other variants of the invention, any other, correspondingly resistant elements can be used. Furthermore, it is understood that the lid may also have any other shape in other variants of the invention. In particular, it may have a recessed grip or the like to facilitate its operation.

In order to actuate the emergency handle 105, the cover 208.4 must first be pivoted in an emergency situation in a single handle (unlocking action) up to its open position (first operation within the meaning of the TSI), so that the emergency handle 105 then released is and can be pivoted out of its rest position (second operation within the meaning of the TSI) to trigger the release of the door 103.

As FIG. 4 it can be seen, the cover 208.4 on its side facing the emergency handle 105 on a magnetic element 209.3, which cooperates with the emergency handle 105 and / or the housing 206 and holds the lid 208.4 in its closed position to avoid noise.

It is understood that the force of the magnetic element 209.3 may be chosen so large in other variants of the invention that it is sufficient to take over the function of locking the lid 208.4 in its closed position against unintentional actuation. The seal can then be omitted and it may optionally be provided only the above-described mark, which indicates that the lid 208.4 has been opened.

This configuration makes it possible, for example, for appropriately authorized personnel to pivot the cover 208.4 into the open position, in which the emergency handle 105 can be actuated to unlock the door 203. This makes it possible to use the emergency operating device 204 also for a regular local unlocking of the door 203, as may be desired or required, for example, for purposes of maintenance and / or cleaning of the vehicle 201. It is thus advantageously no longer necessary to provide a corresponding separate device for these purposes, the regular local unlocking. Optionally, it may be provided that the authorized personnel reset the beschiebene mark using appropriate tools or tools.

It is understood, moreover, that in other variants of the invention a magnetic element may additionally or alternatively also be arranged on the emergency handle and / or the housing in order to achieve the desired force effect. Likewise, for example, in the region of the pivot axis 208. 1 additionally or alternatively a spring element can be provided which effects a corresponding pretensioning of the cover 208. 4 against the housing 206.

In the present example, the (first) pivot axis 208.1 of the cover 208.4 and the (second) pivot axis 105.2 of the emergency handle 105 extend parallel to one another, so that their pivotal movements take place in a common plane. It is understood, however, that in other variants of the invention can also be provided that the two pivot planes transverse to each other, in particular perpendicular to each other. Such an arrangement of the pivot axes or pivot planes has the advantage that first the lid must be deliberately opened by a certain (depending on the position of the pivot planes different sizes) pivot angle before the emergency handle can be actuated, so that an erroneous operation is less likely. In the present example, this securing is achieved in that the handle 105.1 is arranged between the two pivot axes 208.1 and 105.2, so that opposing pivoting movements when opening the cover 208.4 or when pressing the emergency handle 105 are required.

How the particular FIG. 4 can be seen, the retaining element 208.5 is simply attached to the housing 206 via fasteners 208.8. This design has the advantage that the cover 208.4 can be easily adapted to the dimensions of the housing 206. In particular, the already existing fastening elements for the housing 206 can be used for the fasteners 208.8 (which fix the housing 206 on the car body).

The present invention has been described above by means of examples in which the shield is designed as a one- or two-part assembly. It is understood, however, that in other variants of the invention, a multi-part design of the shield can be provided. For example, it may be designed as a two-part cover, the halves of which are each pivotally hinged to the housing.
