Description

[0059] An exemplary embodiment of the invention will be described below on the basis of the drawing. Shown is:

[0060] FIG. 1 a perspective, schematic illustration of an embodiment of the path and road barrier according to the invention.

[0061] FIG. 1 shows schematically a very simplified illustration of an exemplary embodiment of the present invention with the key elements. Alternative embodiments are conceivable in large number and can modify various ones of the fundamentally likewise present elements.

[0062] Seen is a path and road barrier. Not depicted is a ground surface that forms a driving surface for vehicles, which, in the absence of the path and road barrier, could pass the region of the ground surface on the driving surface of interest here.

[0063] In the illustrated embodiment, however, a situation is to be regarded in which, in particular, a truck arrives from the left at the situation depicted in FIG. 1 and, purely theoretically, desires to leave the FIGURE once again at the top right. Accordingly, it follows the direction indicated by an arrow 15.

[0064] In the ground or in the driving surface, a foundation 10 is set. In practice, a corresponding hole is dug in the driving surface or is utilized and a concrete foundation, which is explained in more detail below, is poured there.

[0065] It is seen in FIG. 1 that the foundation 10 rests against the top side 11, which is flush with the ground surface, which is not depicted. The ground adjoins the foundation 10 in the simplified illustration of FIG. 1 at a plurality of lateral surfaces 12.

[0066] Situated inside of the foundation 10 in the central region is a quiver apparatus 20. In many preferred embodiments, this quiver apparatus 20 is cast along with the casting of the foundation 10, so that it cannot be removed with substantial forces. In the illustrated embodiment, the quiver apparatus has two recesses 21 and 22 and a quiver cover 23.

[0067] The quiver cover 23 is flush with the top side 11 of the foundation 10 and thus also with the ground surface and the driving surface.

[0068] Moreover, the quiver apparatus 20 is supported by two reinforcing elements, which are co-cast in the foundation 10. In the illustrated embodiment, these reinforcing elements 24 and 25 take the form of rails in order to assist still further the anchoring of the entire quiver apparatus 20 inside of the foundation 10. Instead of rails, it is also possible to use bars, pipes, panels, or rods with rectangular cross sections.

[0069] Accordingly, all of the above-described elements lie below the ground surface or reach it. Without the further parts yet to be described below, it would be possible to travel over the driving surface in the indicated preferred direction 15 of the truck.

[0070] The two recesses 21 and 22 in the quiver apparatus 20 are not covered by the quiver cover 23. Instead, a bollard barrier 30 is provided here. The bollard barrier part 30 consists of a plurality of parallel panels 31, 32, 33, 34. Illustrated in FIG. 1 are four parallel identical panels 31, 32, 33, 34. However, a different number of panels is also possible and they need not necessarily all be identical.

[0071] However, it is relevant that these panels are each constructed to be flat, with the planes of the faces lying essentially in the same plane as the presumed direction of travel of a truck or other vehicle approaching the path and road barrier. If such a vehicle were to come barreling towards the path and road barrier in the impact direction 15 and, from the ground surface, reach the top side 11 of the foundation 10, the vehicle, which is not depicted, would impact at the left impact face 35 of the bollard barrier part 30 in FIG. 1.

[0072] As can be seen, this impact face 35 is spanned by the narrow sides of the adjacently lying panels 31, 32, 33, 34 of the bollard barrier part 30.

[0073] The preferred embodiment of FIG. 1 already shows in the schematic view that the impact face 35 is curved, whereby, directed upwards, this curvature is oriented towards the approaching vehicle, that is, opposite to the impact direction 15.

[0074] The advantage of this concept lies in the fact that the vehicle is forced downwards when it impacts against the impact face 35 of the bollard barrier part 30 of the path and road barrier. This additionally prevents the vehicle from surmounting the obstacle formed by the path and road barrier.

[0075] The panel-shaped construction of the bollard barrier part 30 additionally stabilizes this bollard barrier part 30. The arrangement of a plurality of panels 31, 32, 33, 34 adjacent to one another in relation to the direction of impact results in the impacting vehicle losing additional kinetic energy when the panels rub against one another during impact or are bent against one another in the case of greater energy input and are thereby also possibly destroyed.

[0076] This effect of an energy absorption due to plastic deformation of the structure and a crushing together of the panels or layers is capable of stopping the approaching vehicle in an effective manner and also causes damage to the axles and other components of the vehicle.

[0077] In various embodiments, the panels can also be joined to one another by bolting or by adhesive bonding. It is also possible to arrange them at an even spacing or else at irregular spacings parallel with respect to one another.

[0078] In the case of a concept involving a plurality of bollard barrier parts of this kind or a plurality of path and road barriers of this kind for blocking off a broader region, it is also possible to join the panels of various bollard barrier parts 30 to one another by means of rigid pipes or solid rods of diverse cross section or else to choose flexible connectors in the form of chains or cords. In this way, it is possible to provide additional holding force or resistance energy against approaching vehicles.

[0079] However, the greatest advantage of the construction with the parallel panels lies in the fact that a very economical prefabrication of the parts of path and road barriers of this kind is possible. Namely, depending on need and location, it is essentially possible to decide spontaneously whether a bollard barrier part 30 is built out of four or five or seven or even ten panels of the same kind. The prerequisite is solely that the recesses 21 and 22 in the associated quiver apparatus 20 are large enough.

[0080] The structure consisting of a plurality of panels also makes it possible to construct the bollard barrier part 30 by manual manipulation, because it is possible for each individual panel to have a weight of less than 55 kilograms. It can therefore be handled by one person or by a few persons in order to insert successively a plurality of panels of the bollard barrier part 30 into the quiver apparatus 20 or into the recesses 21 and 22.

[0081] Besides the modular expandability of the bollard barrier parts 30 for higher so-called impact classes, a structure that is optimized in terms of topology can be provided.

[0082] Not illustrated are further possibilities, such as, for example, additional fastening elements for blocking pedestrian traffic or bicycle traffic from passing between two bollard barrier parts.

[0083] It can also be seen that the bollard barrier part 30, consisting of adjacently arranged panels 31, 32, 33, 34, has a structure that resembles an “A.” For stiffening of the bollard barrier part 30, it is preferred to insert stiffening struts 38 between the impact face 35, which faces towards the approaching vehicle, and the back face 37, which faces away from the approaching vehicle, as a result of which the appearance of an “A” is created.

[0084] What is thus created overall is a panel 31, 32, 33, 34 having an edge that faces the vehicle and becomes a part of the impact face 35 of the entire bollard barrier part 30 and a back face 37 that faces away from the vehicle. The impact face 35 and the back face 37 are joined to one another through one stiffening strut or a plurality of stiffening struts 38. In this way, material recesses in the panel 31, 32, 33, 34 are formed between the edges and the stiffening struts 38.

[0085] The number of panels employed in a bollard barrier part 30 also depends on the impact loads that the path and road barrier will have to absorb. For the personnel engaged in creating the path and road barrier to be able to handle the panels manually, the panels cannot exceed a certain weight. In itself, this poses no problem, because it is possible by way of a larger number of panels to absorb any impact load.

[0086] The two outer panels 31 and 34 in the illustrated embodiment have side faces 36. These side faces can be utilized for attaching posters, advertising displays, company logos, emblems, or laser engravings or for other purposes of use. If, for example, such a blocking is employed near to a soccer stadium, the emblems of the sport club can be utilized here.

[0087] The individual panels 31, 32, 33, 34 of the bollard barrier part 30 can, for example, be constructed of crane structural steel, bainitic steel, martensite phase steel, or other high-strength steels. Also coming into consideration are fiber composite materials. In combination with the high-strength steel, panels composed of resilient elements can also be employed.

[0088] In the case of a material mix of the individual panels, a hybrid concept is created, which likewise has advantages for certain cases of application.

[0089] Besides the already described curvature in the impact direction or negative curvature, which leads to the application of a force against the vehicle, it is also possible to provide a height gradation of the panels. In this way, it is possible to choose the modular stiffness of the bearing structure and it is possible to target the destruction or capture of various structural components of the impacting vehicle. It is thereby possible to take into consideration any assumptions regarding the structure of the impacting vehicle.

[0090] The elements of the quiver apparatus 20 can also make use of crane structural steel, bainitic steel, martensite phase steel, fiber composite materials, and other materials.

[0091] It is also possible to provide the recesses 21 and 22 of the quiver apparatus 20 with a stronger horizontal component in order to work together with differently formed panel-like bollard barrier parts.

[0092] In further embodiments, which are not illustrated, it is also possible for the quiver apparatus 20 to be furnished with additional molded elements, which act to prevent the panels 31, 32, 33, 34 of the bollard barrier part 30 from being pulled out, namely, during both an impact of a vehicle and in the case of vandalism.

[0093] Also not depicted is the provision of a covered cable feedthrough in the foundation 10 in the recesses 21 and 22 of the quiver apparatus 20 and, from there, into the bollard barrier part 30 in order to provide an illumination. This illumination can occur for purposes of design, but also in order to prevent a vehicle from inadvertently driving against the path and road barrier at night.

[0094] The concept of the construction from a plurality of panels can be utilized, in addition, to provide shapes in the region of the bollard barrier part 30 that are not relevant in functional terms. Examples include images of palms or stars.

[0095] Smaller spikes can also be provided on the impact face 35 of the bollard barrier part 30 and, during an impact of the vehicle against the path and road barrier, can lead to additional damage to the vehicle.

[0096] The layered construction consisting of a plurality of panels has still a further advantage. A strong impact of a vehicle can create damage, such as, for example, cracks, in regions of a bollard barrier part 30. However, a crack in one of the panels 31, 32, 33, 34 does not lead to propagation of this crack into adjacent panels. Only one of the panels is therefore damaged, whereas the other panels are not affected. This increases the durability of the entire path and road barrier in the case, for example, of a massive impact involving a number of vehicles in succession.

[0097] Inside of the recesses 21 and 22 of the quiver apparatus 20, the panels 31, 32, 33, 34 of the bollard barrier part 30 can also be arranged in a tailored manner with respect to one another in accordance with the wedge principle, that is, for example, at angles of 15° with respect to one another. This results in a self-locking and a frictionally fitted bracing against being pulled out.
