Anti-climbing device for a rail vehicle

Description

[0001] The present invention relates to an anti-climbing device for a coupling section of a rail vehicle, in particular a tram, in which two car bodies are coupled, in particular via an Albert coupling, by means of a first coupling device of a first car body and a second coupling device of a second car body. The anti-climbing device is designed to be detachably connected to the coupling section, the anti-climbing device comprising at least one component to which a further component of the anti-climbing device can be fastened. The present invention further relates to a rail vehicle, in particular a tram, having such an anti-climbing device.

[0002] In public passenger transport in the rail vehicle sector, rail vehicles frequently stop, particularly on regional trains, subways, and trams. In addition, these types of rail vehicles, with a lower nominal operating speed compared to high-speed rail vehicles, typically have a relatively wide coupling section between two coupled car bodies. Especially when these rail vehicles are used in urban areas or rural areas with a manageable number of track crossings, passengers may be tempted, especially in a hurry, to see a "suitable shortcut" to their planned route by stepping over a coupling section of a stopped tram, subway, or regional train.Such a crossing not only poses a danger to the person acting – for example, if the rail vehicle resumes speed during the crossing – but also endangers other road users, such as a cyclist or car driver who, when passing the stopped rail vehicle, relies on passengers or other pedestrians crossing the busy roadway exclusively at the designated exits or at the ends of the rail vehicle. Last but not least, a person crossing the coupling section (especially if hectic or inattentive) can also cause damage to the couplings, car bodies, wheel sets, etc.

[0003] In some known rail vehicles with anti-climbing devices, such as those in US 3,532,063, EP 1473207 A1, or US 6,244,324 B1, quite effective device protection devices are provided as a solution to this problem. Further anti-climbing devices are also known from XP093020340, XP093020343, XP093020351, XP093020359, and XP093020364. Some of these known solutions are very effective in providing a high degree of prevention against climbing over the coupling section through the design of an anti-climbing device.However, these known systems have the disadvantage that their implementation of anti-climbing protection requires complex structures with built-in components and / or attachments at the end areas of the coupled car bodies. Such complex devices are not only proposed for retrofitted anti-climbing devices on existing, older rail vehicles, but are also described for new rail vehicles yet to be manufactured. Another disadvantage of these known systems is that the known designed, manufactured, and installed anti-climbing devices are usually only suitable for a specific pairing of coupled car bodies with a specific car body geometry for which they were ultimately designed.This not only increases the design effort, manufacturing effort and installation time for the use of anti-climbing devices in several different rail vehicles, but it also shows that such known anti-climbing devices are not suitable for use in an operating environment that is intended to ensure a flexible recoupling process of car bodies.

[0004] The present invention is therefore based on the object of providing an anti-climbing device or a rail vehicle of the type mentioned at the outset, which does not have the above-mentioned disadvantages or at least has them to a lesser extent and, in particular with a simple design, enables a compact and reliable connection of the anti-climbing device to the rail vehicle.

[0005] The present invention solves this problem starting from an anti-climbing device according to the preamble of claim 1 by the features specified in the characterizing part of claim 1.

[0006] The present invention is based on the technical teaching that, with a simple design, a compact and reliable, detachable connection of the anti-climbing device to the rail vehicle is possible if the anti-climbing device engages with the rail vehicle via two end sections of the anti-climbing device by inserting or pushing one end section into an associated receiving device on an associated coupling device. For this purpose, a receiving device is arranged on each of the couplings of the two car bodies to be coupled. Advantageously, the receiving devices each have two receiving device elements with recesses that are spaced apart from one another in a vertical direction, wherein each of the recesses interacts with an end section.It is particularly advantageous if two car bodies are coupled together with Albert couplings, as these already have such mounting devices integrated as standard, thus further minimizing the design and financial effort for providing an anti-climbing device on a rail vehicle.

[0007] Due to this simple construction (in particular due to the two receiving device elements spaced apart from one another in the vertical direction), a reliable but detachable connection of the climbing protection device to the rail vehicle can be established by inserting or passing two end sections (in particular as parts of two legs of a U-shaped component) of the climbing protection device into the receiving devices arranged on the couplings.

[0008] The information or warning function can be reliably fulfilled by designing that part of the anti-climbing device which is located vertically above the two inserted end sections accordingly. The present invention has recognized that in order to reliably implement the warning and preventive function which an anti-climbing device is supposed to have, it is sufficient, on the basis of this simple, reliable, detachable connection with the couplings by two end sections (of a particularly shaped U-shaped part), to design the part of the anti-climbing device which is located vertically above it in a relatively compact manner with a connectable information device (e.g. warning sign). Neither further fastening means are required to maintain the positioning required during operation (iewithout wobbling) nor a direct connection of any part of the anti-climbing device to the car bodies, in particular not to the (often complexly curved) car body end areas, in order to keep the anti-climbing device stable during operation of the rail vehicle.

[0009] In addition, the design, in which the anti-climbing device is in direct connection with the rail vehicle exclusively via the coupling parts or halves and is thus fundamentally completely independent of the design of the car body ends, massively increases the flexibility of using a specific version of an anti-climbing device for different pairings of coupled car bodies with different car body end area geometries.

[0010] Furthermore, by designing the anti-climbing device from two monolithic plastic components that can be assembled via a snap connection, a very compact and lightweight device can be created, which has a positive impact on transport and assembly for the paving personnel. It is particularly advantageous if the plastic components are manufactured using a 3D printing process. This allows for a large number of components for an anti-climbing device to be created quickly and precisely in terms of geometry and plastic composition.When choosing the design of the anti-climbing device from plastic, for example in the form of a thermoplastic plastic, in particular a polyetherimide (for example ULTEM ™< 9085), or a fiber-reinforced plastic, it is also particularly advantageous that in this case weather conditions do not have a noticeable effect on the service life of the device.

[0011] According to one aspect, the present invention therefore relates to an anti-climbing device for a coupling section of a rail vehicle, in particular a tram, in which two car bodies are coupled, in particular via an Albert coupling, by means of a first coupling device of a first car body and a second coupling device of a second car body. The anti-climbing device is designed to be detachably connected to the coupling section, wherein the anti-climbing device comprises at least one component to which a further component of the anti-climbing device can be fastened. A first end section of the component is designed to be detachably connected to the first coupling device in an assembled state of the anti-climbing device by inserting the first end section into a first receiving device of the first coupling device.A second end portion of the component is designed to be detachably connected to the second coupling device in the assembled state of the anti-climbing device by inserting the second end portion into a second receiving device on the second coupling device (110).

[0012] A first end portion of the component, which is located in the region of a first end of the second component, can be designed to be detachably connected to a first coupling device located within the coupling section in an assembled state of the anti-climbing device on the coupling section by pushing a part of the first end portion through the first receiving device for detachable connection.

[0013] The first receiving device can comprise two receiving device elements spaced apart from one another in the vertical direction of the rail vehicle, each having a first recess. The recesses are arranged relative to one another in such a way that a connecting line between their centers runs parallel to the vertical direction.

[0014] A second end section of the component, which is located in the region of a second end of the component, can be designed to be detachably connected to the second coupling device, which is located within the coupling section, when the anti-climbing device is mounted on the coupling section, by pushing the second end section through a second receiving device for detachable connection. The second receiving device can comprise two receiving device elements spaced apart from one another in the vertical direction of the rail vehicle, each having a second recess. The recesses can, in particular, be arranged relative to one another such that a connecting line between their centers runs parallel to the vertical direction.

[0015] The anti-climbing device can be designed to establish a detachable connection to the rail vehicle exclusively via a direct connection of the component to the first and second coupling device in a coupling section, wherein the coupling section is defined such that it does not enclose the two coupled car bodies, thus does not enclose any area of ​​the two coupled car bodies.

[0016] Through the clever use of a first and a second receiving device, each with two spaced-apart receiving device elements with first and second recesses, the first and second end sections of the anti-climbing device can be easily inserted so deeply into the corresponding recesses that this measure alone creates a reliable, detachable connection between the anti-climbing device and the coupling section. In other words, with a sufficiently large insertion depth of the first and second end sections, the anti-climbing device reliably withstands the expected dynamic forces during operation of the rail vehicle.

[0017] This allows for a particularly simple and reliable design, and (unlike known connections between a step-over protection device and a rail vehicle) the present invention eliminates the need for any additional connection to the rail vehicle. In particular, a direct connection of the step-over protection device to the coupled car bodies, in particular the car body end areas, is eliminated. By eliminating a direct connection to the car body ends, a step-over protection device can be implemented in a particularly simple manner, regardless of the design, in particular the end areas, of the coupled car bodies.

[0018] Furthermore, in the case of an Albert coupling, such an arrangement with a receiving device having two receiving device elements spaced apart from one another in the vertical direction is advantageously already part of the coupling, and these elements can be used when coupling two car bodies with Albert couplings if these receiving devices do not need to be used for other purposes. Thus, in particularly preferred and simple variants of the invention relating to an Albert coupling, in particular when used in tram systems, no modifications or additions to existing vehicle couplings are necessary in order to mount the anti-climbing device according to the invention. In this case of the Albert coupling, the size of the recess in the receiving device simply indicates the cross-sectional area and cross-sectional shape (namely circular) of the two end sections of the second component.

[0019] For couplings that are not designed as Albert couplings, the first or second receiving device can be attached to the first or second coupling through manufacturing steps, provided this is technically permissible / compliant with standards. For example, it is conceivable to weld a first or second receiving device to a first or second coupling as described above, or to fix it to the first or second coupling using additional auxiliary structures, particularly in conjunction with screw connections.

[0020] The component and the further component can in principle be designed geometrically in any suitable manner, as long as they are suitable for the required reliable detachable connection in the receiving devices on the coupling section and in the operation of the rail vehicle.

[0021] According to the invention, a quick-action snap-in connection is provided which is arranged and interacts with the component and the further component in such a way that it releasably connects the components to one another.

[0022] In preferred variants of the invention, however, the further component of the anti-climbing device is substantially rod-shaped, at least in sections in the main extension direction of the further component. In this preferred variant, however, the component is substantially U-shaped, wherein the second component comprises a substantially rod-shaped base section, at the first end of which, at an angle to the base section, a substantially rod-shaped first leg is formed, which comprises the first end section, and at the second end of which, at an angle to the base section, a substantially rod-shaped second leg is formed, which comprises the second end section.

[0023] In particularly simple variants of the invention, the further component of the anti-climbing device is essentially rod-shaped with a main direction of extension and a rod cross-section transverse to the main direction of extension in the form of a tube (i.e. in the form of a tube cross-section). Depending on the technical requirements, this can be a solid tube or a hollow tube cross-section. The component can be essentially U-shaped, wherein the second component comprises an essentially rod-shaped base section with a tube cross-sectional profile, at the first end of which an essentially rod-shaped first leg is formed, angled away from the base section and curved in the transition, which comprises and forms at least one first leg tube cross-section in the region close to the transition to the base section.The first leg also includes the first end portion formed with at least one first end portion tube cross-section.

[0024] In the same way, a substantially rod-shaped second leg can be formed, starting from a second end of the rod-shaped base section, angled and curved at the transition from the base section, which comprises and forms at least one second leg tube cross-section in the region near the transition to the base section. Here, too, the second leg comprises the second end section, which is formed with at least one second end section tube cross-section.

[0025] Thus, in the simplest case, the first or second leg has a first or second leg tube cross-section in a region near the transition to the base section, as well as a first or second end section tube cross-section in the region near the open end of the first or second leg. Through this simple design with a notch or "step transition," as well as through the clever choice of the position of this notch, preferably relatively close to the transition to the base section, the first or second leg can be easily inserted so deeply into the corresponding bore in the first or second receiving device that, on the one hand, this alone ensures the required reliable, detachable connection of the anti-climbing device to the coupling section during operation, as described above. On the other hand, the first or second leg rests on the end section.the second leg is detachable due to the arrangement of the notch and at the location of the notch on the upper one in the vertical direction of the respective receiving device elements of the first or second receiving device, whereby the positioning and connection of the second U-shaped component relative to the first and second coupling is improved, since the position of the notch allows the position of the anti-climb device of the couplings and thus also the penetration depth of the first or second end section (which is decisive for the reliability of the detachable connection) to be precisely defined or controlled in advance in the planning phase and thus, among other things, a potentially undesirable resting of the second component on the stop, i.e. in the transition area to the base element, on the receiving devices or on intermediate obstacles such as coupling metal pins, etc. is avoided.

[0026] The two first and two second recesses which interact with the first and second legs, in particular with the first and second end sections, in the mounted state of the anti-climbing device are preferably designed in the form of two first bores and two second bores.

[0027] The choice of the cross-sectional profile of the U-shaped second component, namely in the form of a first and second end section pipe cross-section and associated therewith also a constant curvature in the cross-sectional profile and in the main extension direction of the U-shaped second component a smooth transition from the base section to the respective adjacent legs without forming sharp edges, not only brings advantages in the manufacture of the plastic component, which is preferably manufactured using a 3D printing process, but also has the advantage that the assembly and disassembly of the anti-climbing device can be carried out more quickly by specialist personnel, since the respective end section of the second component can be inserted into the associated coupling more easily and therefore more quickly when there are holes in the receiving device than, for example, with a rectangular cross-section of the end section and a rectangular recess.In addition, the risk of injury to the specialist personnel is reduced due to the lack of sharp edges on the second component during assembly and disassembly.

[0028] This advantage can also be easily realized by using Albert couplings, since the existing recesses in an Albert coupling already have recesses in the form of holes.

[0029] As already mentioned above, the arrangement of a notch or "step transition" on the first or second leg is particularly preferred. In the case of tubular component cross-sections and bores as recesses in the first or second receiving device, it is therefore preferably provided that the first leg tube cross-section is larger than the first end section tube cross-section and / or the second leg tube cross-section is larger than the second end section tube cross-section. This makes it possible to achieve the advantages described above, which a clever notch arrangement provides for a reliable, detachable connection and good positioning of the anti-climb device relative to the first or second receiving device.

[0030] As mentioned above, the variants described above already make it possible to establish a reliable, detachable connection between the anti-climbing device and the rail vehicle when mounted for operation. This connection is defined as being reliable in terms of the dynamic forces expected during operation of the rail vehicle.

[0031] Additionally, it may be advantageous to provide a means of securing the anti-climbing device on the first and / or second coupling in the coupling section, which is designed to protect the anti-climbing device against unauthorized removal from the first and / or second receiving device. Examples of this include securing against violent external influences, against attempted theft, and also against unforeseeably high dynamic forces resulting, for example, from very strong wind forces.

[0032] In order to remedy this, preferred variants of the invention further provide at least one securing element which is designed and arranged in the coupling section in such a way as to secure at least one of the first end section and the second end section of the anti-climbing device in the assembled and mounted state against unauthorized removal from the associated receiving device.

[0033] In this case, the at least one securing element for authorized removal can be designed to release the anti-climbing device relative to the associated receiving device in the coupling section with a simple movement of the hand. For this purpose, the at least one securing element can additionally or alternatively comprise a locking device, for example in the form of a padlock with a key, so that simple measures ensure, as far as possible, that only authorized persons can remove or dismantle the anti-climbing device with a simple movement of the hand and with the corresponding unlocking device for the locking device.

[0034] Additionally or alternatively, the at least one securing element can be designed in the manner of a spring pin. This allows for protection against unpredictably high dynamic forces, for example, resulting from very strong wind forces.

[0035] In further variants, with regard to securing the anti-climbing device, a first securing element is provided which is designed and interacts with the first coupling device and the first end section of the anti-climbing device in the mounted state, and in particular additionally in the assembled state, in such a way that the anti-climbing device is substantially secured against unauthorized removal from the first receiving device. Furthermore, in this variant, a second securing element is provided which is designed and interacts with the second coupling device and the second end section of the anti-climbing device in the mounted state, and in particular additionally in the assembled state, in such a way that the anti-climbing device is substantially secured against unauthorized removal from the second receiving device.

[0036] At least one of the securing elements can be designed for authorized removal to release the anti-climbing device relative to the associated receiving device in the coupling section with a simple manual action. Additionally or alternatively, at least one of the securing elements can be designed in the manner of a spring pin. Additionally or alternatively, at least one of the securing elements can comprise a locking device, preferably in the form of a padlock with a key. With these configurations of the securing devices, the advantages already mentioned can be achieved and, in particular, security against unauthorized removal can be improved by providing a first and a second securing element.

[0037] In principle, the component and / or the additional component can be made of any suitable plastic and, in this regard, can be manufactured using any suitable manufacturing process. However, in preferred variants of the invention, the component and / or the additional component of the anti-climbing device consists of a plastic, for example a thermoplastic, in particular a polyetherimide (e.g., ULTEM™< 9085), or a fiber-reinforced plastic. These have the advantage that they are weather-resistant, have a low specific gravity, and their composition and component geometries are easily controllable during the manufacturing process. Manufacturing using 3D printing is particularly suitable for this purpose.

[0038] Additionally or alternatively, the component and / or the further component can therefore be designed to be manufactured using a 3D printing process. These 3D printing processes offer the advantage, particularly when processing plastic, that the components can be manufactured quickly and with precise geometry, and the local composition / local properties of the component to be manufactured can be easily controlled during the 3D printing process. In principle, any plastic that can be processed using 3D printing and has sufficient rigidity and strength for the application can be used. A further advantage of using 3D printing processes is that complex geometries, which are required due to the design of the vehicle coupling and its components, can be manufactured easily and cost-effectively.

[0039] Additionally or alternatively, the component and / or the further component in the assembled and mounted state on the coupling section can have a clear height in the range of 650 mm to 1200 mm, preferably in the range of 800 mm to 1000 mm, more preferably approximately 900 mm and a clear width in the range of 150 mm to 700 mm, preferably in the range of 200 mm to 600 mm, more preferably approximately 500 mm.

[0040] Additionally or alternatively, the component and / or the further component in the assembled state can have a weight in the range of 0.5 kg to 2.0 kg, preferably in the range of 0.8 kg to 1.8 kg, more preferably of approximately 0.9 kg.

[0041] In order to advise or warn persons not to climb over the coupled car bodies of the rail vehicle under any circumstances, the warning device provided for this purpose, which can be attached to the anti-climbing device according to the invention, can in principle have any suitable geometry and form of warning (for example via signs, via sounds or via flashing lights).

[0042] In particularly simple variants, the additional component of the anti-climb device in the form of the information device holder is designed such that the information device in the form of a sign, particularly made of metal or plastic, can be releasably attached to it. Additionally or alternatively, the information device can be releasably adhered in the form of a, particularly weather-resistant, information sticker. This form is particularly quick to apply and cost-effective with a suitable base. Additionally or alternatively, the information device can be releasably attached in the form of an information lamp. With such a design, it can be assumed in particular that a person potentially tempted to climb over will become aware of the warning.

[0043] In particularly advantageous variants, particularly those that are particularly easy to manufacture when manufacturing the first component using 3D printing processes, the further component of the anti-climbing device in the form of the indicator holder can be designed such that a rod-shaped part of the further component is adjoined in its main direction of extent by a disc-shaped part of the further component, the main direction of extent of which is parallel to the main direction of extent of the rod-shaped part, so that the further component has the shape of a "badminton racket." The disc-shaped part is designed to releasably fix the indicator in the form of a sign, in particular made of metal or plastic. Additionally or alternatively, the disc-shaped part is designed to releasably fix the indicator in the form of an indicator lamp device.Additionally or alternatively, the disc-shaped part is designed to make the information device in the form of a, in particular weather-resistant, information sticker detachably adhesive.

[0044] Due to this simple geometry of the first component, which is preferably manufactured efficiently and precisely by a 3D printing process, a large number of different warning devices can be installed alone or in combination in a simple manner and in sufficient size for the purpose of preventing overstepping.

[0045] The rail vehicle equipped with the described anti-climbing device can, in principle, be any type of rail vehicle suitable for the anti-climbing device according to the invention. This includes, among others, trams, regional trains, and subways.

[0046] In particular, the provision of the anti-climbing device according to the invention in coupled rail vehicles with Albert couplings, including in existing trams, in emergency couplings for towing maneuvers in the event of technical malfunctions or accidents, or in low-floor trams, brings the advantages described above to particular effect, in particular since in principle no changes at all to the rail vehicle itself, nor to the coupling, are required in order to reliably mount the anti-climbing device according to the invention.

[0047] In preferred variants, the rail vehicle may additionally or alternatively be a rail vehicle with a nominal operating speed below 100 km / h, preferably below 90 km / h, more preferably below 80 km / h.

[0048] It is understood that the described rail vehicle can have more than two coupled car bodies and that, in the case of a plurality of coupled car bodies, an anti-climbing device according to the invention can be mounted between each two coupled car bodies as required.

[0049] The variants and advantages described above in connection with the rail vehicle also apply mutatis mutandis to the anti-climbing device according to the invention, since the anti-climbing device according to the invention either has these features of the rail vehicle itself or is designed to interact with them. Therefore, reference is made to the above explanations in this regard.

[0050] Further preferred embodiments of the invention emerge from the dependent claims and the following description of preferred embodiments, which refers to the accompanying drawings. They show: Figure 1 shows a side view of a preferred embodiment of a rail vehicle according to the invention with a preferred embodiment of the anti-climbing device according to the invention; Figure 2 shows a perspective view of a part of the anti-climbing device from Figure 1 . Example

[0051] In the following, with reference to the Figures 1 and 2 A preferred embodiment of the rail vehicle 101 according to the invention in the form of a tram is described, which has a vehicle longitudinal axis 101.1. To facilitate understanding of the following explanations, a vehicle coordinate system x, y, z is indicated in the figures, in which the x-coordinate denotes the longitudinal direction of the rail vehicle 101, the y-coordinate denotes the transverse direction of the rail vehicle 101, and the z-coordinate denotes the vertical direction of the rail vehicle 101.

[0052] Figure 1shows a schematic view of the rail vehicle 101. The vehicle 101 comprises a first car body 102 and a car body 103, which are coupled to one another via Albert couplings and form a coupling section 104. In this coupling section, an anti-climbing device 105 is mounted, which consists of a first rod-shaped plastic component 106 with a solid tubular cross-section and a U-shaped, bent second rod-shaped plastic part 107 with a solid tubular cross-section, which can be brought into an assembled state via a snap connection 108 and can be easily detached again if necessary. The anti-climbing device 105 is detachably connected to the tram via the U-shaped component 107 in a reliable manner (i.e., permanently reliably mounted even during operation) and is connected exclusively via the coupling section 104. For this purpose, a first end section 107 is provided.1 as part of a first leg 107.11 of the U-shaped component 107 is inserted into a first receiving device 109.1 of a first coupling 109 of the first car body 102. Similarly, a second end section 107.2 as part of a second leg 107.22 of the U-shaped component 107 is inserted into a second receiving device 110.1 of a second coupling 110 of the second car body 103. The two legs 107.11 and 107.22 are connected to one another via a rod-shaped, solid-tubular base section 107.3.

[0053] As especially in Figure 2As can be seen, the first receiving device 109.1 (and in the same way also valid for the second receiving device 110.1) consists of two receiving device elements 109.2 and 109.3 which are spaced apart from one another in the vertical direction and each have a bore which is designed so that the first end section 107.1 is pushed through it and thus the anti-climbing device 105 reaches its mounted state, ie the reliable, detachable connection with the rail vehicle 101 is established directly via the coupling section 104. In the present example, the first receiving device 109.1 is already an integral part of the first coupling 109, so that a separate attachment (e.g.via welding processes or via further auxiliary constructions, in particular constructions with screw connections) of such a receiving device can be dispensed with in this embodiment and the design effort for the provision of the climb-over protection device according to the invention is further minimized.

[0054] Thus, in the present example, the bore diameter of the first receiving device 109.1 (and in the same way for the second receiving device or the second leg) already simply specifies a first end section pipe diameter EAD1 (EAD2 for the second end section pipe diameter) of the first end section 107.1 in order to establish the detachable connection between the anti-climbing device 105 and the rail vehicle 101.

[0055] As well as Figure 2As shown, in the present example, the first leg 107.11 (again, this applies equally to the second leg 107.22 and the second receiving device 110.1) has, in addition to the first end section tube diameter EAD1, also a first leg tube diameter SRD1, which is larger than the first end section tube diameter EAD1. This design simply creates a "step transition." By skillfully selecting its position along the main extension direction of the first leg, namely relatively close to the transition of the leg to the base section 107.3, the bearing surface of the U-shaped part on the receiving device 109.1 is precisely determined and, consequently, the insertion depth into the receiving device 109.1 (i.e., into the two receiving device elements 109.2 and 109.3) is precisely determined. This increases the positioning of the anti-climbing protection device and the reliability of the detachable connection.The intended insertion depth of the first end section is such that the first end section is also inserted into the lower of the two receiving device elements 109.3, which has a particularly advantageous effect on the positioning stability during operation of the rail vehicle, since any wobbling of the device relative to the vehicle is reduced by the plurality of support points provided for the end section.

[0056] In the present example, as can be seen Figure 2As can be seen, the rail vehicle further comprises a first spring pin 111.1 at a connecting area between the first receiving device 109.1 and the first end section 107.1 to secure the anti-climbing device against unauthorized removal (in the same way, a second spring pin 111.2 is provided at a connecting area between the second receiving device 109.2 and the second end section 107.2). In this case, as is also provided in this example, it is suitable for the first spring pin to be arranged vertically below the lower edge of the lower of the two receiving device elements 109.3.

[0057] The first and second plastic parts 106 and 107 of the anti-climb device 105 are made of the thermoplastic Ultem™< 9085 (a polyetherimide) using a 3D printing process. This allows for the rapid production of particularly lightweight components with a precise shape.

[0058] In the present example, the anti-climbing device 105 has a clear height of approximately 900 mm, a clear width of approximately 500 mm and a weight of approximately 0.9 kg.

[0059] The warning or information function to prevent people from climbing over the barrier is implemented in this example in a particularly simple manner, as in Figure 1 shown, is realized by an information device in the form of a sign, said information device being mounted on the first plastic part 106, namely on a disc-shaped part of the first plastic part 106, which continues from one of the rod-shaped ends of the first component; in the present example, the first plastic part has a geometry in the manner of a "badminton racket" (in Figure 1 not visible). The first plastic part 106 is thus designed as an indicator holder.

[0060] The present invention has been described above exclusively using examples for rail vehicles. However, it is understood that the invention can also be used in connection with any other vehicles, in particular road vehicles.
