    Climbing protection device.
    Technical field
    The invention relates to an anti-climbing device for
    a rail vehicle.
    State of the art
    In the event of a head-on collision of rail vehicles, the collision forces which occur are to be introduced into the assemblies which are designed to absorb and convert the collision energy into deformation energy. These are typically designed as so-called energy dissipation elements, which can be deformed via a specific deformation path and which have a force-displacement characteristic specially designed for this purpose. If the energy absorption capacity of such elements is exhausted, the further collision energy is introduced into the vehicle structure. It should be noted that the underframe of a rail vehicle is significantly stronger than all other assemblies, especially the side walls, end walls and the roof. In the course of a collision between two rail vehicles, one of the rail vehicles can move so that its underframe is pushed over the underframe of the other vehicle (i.e. it climbs up) and thus loads the much less solid area above the underframe with collision energy. This can occur with a vertical offset of the colliding

    catastrophic consequences of the accident, since the passenger compartment of one of the vehicles can be destroyed over a large area. To prevent this effect, so-called anti-climbers are used, which hold the vehicles in their vertical position to each other in the event of a collision. These anti-climbing devices are typically provided at those points of the vehicles which first meet another vehicle and comprise a plate with a horizontally oriented rib structure. In the event of a collision, these rib structures of the colliding anti-climbing devices encounter one another and form a positive connection, which prevents the anti-climbing devices from sliding vertically to one another. However, if the climbing protection devices encounter one another, they have a horizontal displacement relative to one another, i.e. If the anti-climbing devices overlap only partially in the lateral direction, the resulting moments can twist the fastenings of the anti-climbing devices so that the anti-climbing devices slide laterally against one another and consequently lose their effect as a result. This can occur in particular if the surface of the anti-climbing device designed with a rib structure has relatively small dimensions and a horizontal offset accordingly has a greater effect. The sliding against each other can also be caused by forces occurring in the lateral direction (e.g. collision in a curve). To remedy this defect, baffle plates have been created which allow full-surface toothing, for example by means of
    pyramid-shaped elevations. However, these can

    act only with similar baffle plates and
    are only expensive to manufacture.
    Presentation of the invention
    The invention is therefore based on the object of providing an anti-climbing device for a rail vehicle which slides sideways even when it strikes another anti-climbing device horizontally or when lateral forces occur
    prevented.
    The object is achieved by a climbing protection device with the features of claim 1. Beneficial
    Refinements are the subject of subordinate claims.
    According to the basic idea of the invention, a climbing protection device for a rail vehicle is described which comprises a baffle plate, a plurality of mutually parallel, projecting first forms having a straight course being arranged on the baffle plate, and furthermore a plurality of mutually parallel, projecting second forms being arranged on the baffle plate a straight course are arranged, which are aligned normal to the first formations, and the extension of the second formations over the surface of the baffle plate is less than the extension of the first formations over the surface of the baffle plate, and wherein the first formations each at points of intersection of the formations have a recess in which the extension of the
    first formation is reduced.

    As a result, the advantage can be achieved of being able to create a climbing protection device which, in addition to preventing the so-called spreading, also prevents the horizontal climbing protection device from sliding against one another in the event of a collision. In the event of a lateral offset of a climbing protection device colliding with one another, the introduction of force into energy dissipation elements arranged behind the climbing protection devices can be optimized in this way, and in this case their energy consumption capacity as well as possible
    be fully exploited.
    According to the invention, an anti-climbing device comprises a baffle plate, which is typically rectangular or square, and moldings arranged on this baffle plate on its impact side. A plurality of first formations are to be provided which protrude like ribs from the baffle plate and which are horizontally aligned in the installed position of the anti-climbing device. This configuration is similar to the anti-climbing devices known from the prior art. The invention further provides to provide a plurality of second formations, which also protrude like ribs from the baffle plate, the first and second formations being oriented at right angles to one another. In the installed position of the anti-climbing device, the second formations are thus arranged vertically. The height (extension) of the second formations over the surface of the baffle plate is to be made smaller than the extension of the first formations over the surface of the baffle plate. At the intersection of the first and the second formations there are recesses in the first
    To provide formations in which the height (extension)

    the first formation locally, is reduced over a certain length.
    Thus, when the inventive anti-climbing device meet, the second (vertical) formations get caught in the recesses of the first (horizontal) shape and the anti-climbing device slide against one another
    prevented in all directions.
    The width of the recesses in the first formations is to be carried out at least with the width of the second formations, so that the second, vertical formations can snap into these recesses. It is particularly advantageous to make the recesses in the first formations wider than the width of the second formations, so that a secure engagement is ensured during a horizontal relative movement of climbing protection devices that meet. The width of the recesses determines a distance (catch area)
    within which it can snap into place.
    The shape of the recesses in the first formations, i.e. their cross section in a vertical view, for example
    rectangular or trapezoidal.
    It is advantageous to reduce the extent of the first shape in the area of the recesses to the extent of the second shape. The advantage to be achieved in this way is that when similar anti-climbing devices are snapped together, complete interlocking is achieved, the first formations of each of the two anti-climbing devices coming into contact with the
    Surface of the corresponding baffle plate and

    wherein the second formations come into contact with the first formations of the corresponding baffle plate in the region of the recesses. This optimal interlocking allows the strength of the anti-climbing devices to be fully exploited. Since this geometric optimum may not be realizable in real operating conditions in the event of collisions, for example due to objects jammed between the anti-climbing devices, for example parts of a vehicle trim, it is advantageous to make the extension of the second shape larger than the overall thickness of the objects (in particular trim parts ), which is trapped between the anti-climbing devices
    can be.
    A climbing protection device according to the invention can be produced from the materials customary for climbing protection devices, in particular from steel or a light metal alloy.
    In the case of anti-climbing devices, dimensions of the baffle plates of approximately 300 mm side length are common, these dimensions, as well as a distance of the first formations of typically 60 mm, can also be implemented with an anti-climbing device according to the invention, so that compatibility with conventional anti-climbing devices is ensured. If a climbing protection device according to the invention encounters a conventional climbing protection device, protection against climbing is provided, but protection against horizontal sliding can only be provided in conjunction with a further climbing protection device according to the invention
    Climbing protection device can be achieved.

    A further preferred embodiment of the invention provides for the extension of the second shape above the baffle plate to be reduced to zero, that is to say it is eliminated. At the same time, however, the recesses must be provided in the first recesses. This creates a horizontal rib structure, which is equipped with a toothing. This toothing can engage in anti-climbing devices with a structure made of second formations and thus prevent the anti-climbing devices from sliding horizontally against one another. This embodiment of the invention is particularly advantageous for the revision of existing conventional anti-climbing devices, since only the recesses in the horizontal formations have to be made. This revision can also be carried out with the anti-climbing device in use, whereby only the removal of material is required, but not the application of a structure from second formations. Protection against horizontal sliding only occurs when hitting a climbing protection device with a complete
    Forming structure according to the invention.
    An anti-climbing device according to the invention can be produced, for example, by means of a casting process as well as by means of a forging process, or the rib structure can be milled from a baffle plate which is made correspondingly thicker. In particular, it is advantageous to weld an anti-climbing device according to the invention from individually prefabricated parts (baffle plate, first and second formations). The simple geometry of this
    Individual parts allow easy prefabrication.

    Formations 4 shown. At the intersection points 7 between the first 3 and second 4 formations, a recess 8 is provided in each of the first formations 3. These recesses 8 have a certain width, this width being larger than the width of the second formations 4 in FIG. 1, as a result of which a larger catch area is achieved. In the exemplary embodiment shown, the extension of the first formations 3 at the recesses 8 is the extension 5 of the second formations
