required retention it is also possible to provide several guide stringers, especially two guide stringers arranged one above the other. Of course, it is also possible to mount additional protection boards on the guide beams, which in this case extend in their longitudinal direction.

The guide stringers can be linked to the barrier bodies by tension bars. For this purpose, the tension bars are tensioned with supports provided inside or attached to the barrier bodies. As for tension bars, they are preferably threaded bars that have at least one section with a thread. By means of the thread it is possible to tension the tension bar by means of a rotation by means of the support. It is preferably an external thread, especially a thick thread. For this purpose, the support has been made with a corresponding internal thread. In this way, it is possible to tighten and tension the guide rail and the barrier body with each other by means of the rotation of the tension bar.

The tension bar is preferably driven from an upper side of the guide rail. For this purpose, the tension bar can have a tension bar head, to which it is possible to apply a corresponding hand grip to rotate the tension bar. In this regard and advantageously and by means of its upper end, the tension bar completely adjusts the guide rail.

In principle, it is also possible to link the guide beam or similar positioning body to the barrier body in order to ensure continuity of the materials, especially by welding. As for the movable locking element, it is provided that it can be moved both manually and also in an automated manner. In the latter case, it is possible to control it for example through a central or decentralized control. It is preferable that the blocking element be displaced by an electromechanical drive. The principle is also possible to swing the pivotable barrier body by means of a corresponding drive, for example, hydraulic, pneumatic or mechanical. In this case it is preferable that said drive takes place by means of the same central or decentralized drive provided for the control of the blocking element.

It is preferable that the front side opposite the barrier body with the locking element has an opening. In this regard, in the closed position of the barrier body, the blocking element is movable at least by sections towards the inside of said opening. In this case, the blocking element may have on its end side, for example, a conical configuration, while the opening has a circular configuration. In this way, it is possible to create a virtually free play link between the conical part of the locking element and the opening, which improves the reciprocal linkage between the fundamental body and the counterpart.

In an alternative configuration the claw, referring to its angled hook section, can have an opening of this type. In this way, in the closing position of the barrier body it is possible to guide the blocking element at least by sections through the front side openings and the hook section. The special advantage is that in this way an additional securing of the barrier body against any elevation is ensured in the event of a collision.

As a result, a barrier of guide sleepers is proposed, which in its closed position ensures a secure and durable positional fixation of its free end, which is also the case of high collision loads. By linking several fastening components in the form of coupling means, side cheeks, limiters on the bottom side as well as the coupling plates in combination with the housing opening and the leg, as well as the movable locking element it is ensured that the corresponding barrier body is fixed in terms of its ends with high safety against failures and with a virtually unchanged position in its closed position. In this regard, at least some of the fastening components are configured such that the bonding is still active even if one of the barrier bodies is raised in a limited way from the closed position.

In particular, the combination of inclined and parallel parallel front sides thus allows a large area contact between the free ends of the barrier bodies, especially between their front sides, which advantageously allows the forces to be transmitted in a large area Together with the coupling means and the lateral cheeks, a practically rigid connection to the flexion between the barrier bodies results, which has a positive effect on the possible attainable retention levels.

Within the scope of the invention, a system is also proposed for retaining vehicles for a transit lane, which has releasable guide sleepers juxtaposed with each other and a barrier for guiding sleepers in accordance with the above-mentioned embodiments. It is preferable that the guide sleepers have coupling means and / or housing openings analogous to those of the guide sleeper barriers as well as legs, by means of which they can be interchanged and coupled to each other without problem in the form of a modular principle. The stationary barrier body may also have at its end opposite the front side a coupling means corresponding to the coupling means of the guide sleepers, to be integrated into the vehicle restraint system. The same applies to the configuration of the coupling plate (housing opening, leg). In addition, the support arrangement may have a corresponding coupling means in its region oriented towards the guide sleeves, which corresponds to the coupling means of the guide sleepers, such that the guide cross members can also be coupled with the guide arrangement. support for.

Figure 28 depicts a detail of the barrier of guiding sleepers in the open state of Figures 26 and 27 in a side view.

Figure 1 shows a side view of a barrier of guide sleepers 1 according to the invention. The guide sleeper barrier 1 comprises a first barrier body A and a second barrier body B, which with their lower sides 2 are arranged on their side corresponding to the ground on a subfloor 3 represented in section of a transit lane not shown in more detail. Both barrier bodies A, B are faced with their front sides 4a, 4b, with a strike 5 located between the front sides 4a, 4b bridged by a side cheek 6a. Since the strike 5 is behind the lateral cheek 6a, it cannot be seen directly in this Figure 1.

The front sides 4a, 4b which correspond to each other, are inclined parallel to each other, wherein the first front side 4a and an upper side 7 opposite the lower side 2 of the first front side A encompass each other an inclination angle c1 lower than 90 ° On the other hand, also the second front side 4b and the lower side 2 of the second barrier body B cover an angle of inclination c2 to each other, which is also less than 90 °. In the present both front sides 4a, 4b are oriented parallel to each other, whereby both angles of inclination c1, c2 of the front sides 4a, 4b are identical to each other. In this embodiment, the inclination angles c1, c2 are 15 °.

In the first barrier body A a support arrangement 8 is provided on its end side, which is arranged at the end 9, remote from the first front side 4a of the first barrier body A. The first barrier body is supported by way of being able to pivot at its end 9 by means of a horizontal rotation axis 10 in the support arrangement 8. With reference to the representation of Figure 1, the first barrier body A of the guide sleeper barrier 1 is in a closing position a1.

As for the second barrier body B, it is in this case a stationary part of the barrier of guide sleepers 1, which by means of anchors or anchor baskets, not shown, is linked to locally fixed foundations 11a, 11b, 11c . The foundations 11a, 11b, 11c are located in the plane of the lower side 2 at the same level of the subsoil 3 so they are integrated therein. In contrast, the first barrier body A is located in a manner not fixed on the subfloor 3, its support arrangement 8 being in an extreme position fixed by another foundation 11d on a rail not shown in detail. In this case, the foundation 11d of the support arrangement 8 is arranged below the subsoil s 3, a recess 12 having been provided in the region of the support arrangement 8, within which the support arrangement 8 is disposed on the 11d foundation. The support arrangement 8 is also linked to the foundation 11d by anchors or anchor baskets not shown in detail.

Figure 2 shows the barrier of guide sleepers 1 of Figure 1 in an open position a2. In this case, the first barrier body A is pivoted around the horizontal rotation axis 10. With this, the end 13, opposite the support arrangement 8, of the first barrier body A with its first front side 4a released relative to the second protrudes. front side 4b of the second barrier body B in height. Thanks to the pivoting of the first barrier body A around the horizontal rotation axis 10, an opening 14 is generated, which for example allows the passage of a vehicle over the subfloor 3 through the guide crossbar barrier 1. In the fully position open the barrier body A is pivoted upwards and adopts an angle with respect to the horizontal of up to 90 ° and possibly higher.

As can be recognized with reference to the support arrangement 8, it has a frame 15 that links the first barrier body A with the axis of horizontal rotation 10. The frame 15 is made of an angle profile with flexural rigidity. The horizontal rotation axis 10 is arranged above the upper side 7 of the first barrier body A, and is supported on a strut 16 of the support arrangement 8., The strut 16 is fixed vertically on a floor plate 17 which is extends parallel to each other to the subfloor 3, and by means of which the support arrangement 8 is attached to the foundation 11d. To enable the pivoting of the first barrier body A, between the frame 15 and the floor plate 17 a manipulator 18 is arranged in the form of a cylinder, which by means of the elongation and shortening of its

they show an extension that widens towards the lower side 2, wherein the heels 25a, 25b on the lower side 2 comprise deflections 26a, 26b oriented outwards. By means of the deflections 26a, 26b, which essentially extend parallel to the subsoil 3, a corresponding width is possible and with it a large site area, which allows a stable location of the barrier bodies A, B.

The barrier bodies A, B have at least one internally located connecting plate 27, which joins the heels 25a, 25b in the upper third of the barrier bodies A, B with each other. In addition, on the lower side 2 of the barrier bodies A, B, friction elevating mounting legs 28 are arranged, which oppose a possible displacement of the barrier bodies A, B on the subfloor 3 with a corresponding resistance .

Figure 8 shows the barrier of guide sleepers 1a of Figures 4 and 5 also in a sectional representation mode. Based on the barrier bodies A, B already represented in Figure 7, it shows on the upper side 7 guide stringers 19 additionally arranged. The guide beam 19 is connected to the barrier bodies by means of the tension bars 20. For this purpose, a support 29 is provided in the link plate 27 of the barrier bodies A, B, in which the bars are arranged. tension 20. In this case the tension bar 20 has on its end side an external thread not shown in detail, which is screwed with an internal thread arranged in the support 29 and which has not been represented in detail. As regards the thread, it is preferably a thick thread, so as to allow rapid tensioning and release of the guide beam 19 on the barrier bodies A, B.

The end region opposite the support 29 of the tension bars 20 has a rod head, which can be grasped by means of a suitable hand tool. In this regard, it may be a hexagonal head that can be coupled with a commercially used tool, not shown in detail herein, for example a mouth or ring wrench, as well as an insertion nipple. By means of the rotation movement applicable by means of the tool on the tension bar, the guide bar 19 is tensioned with the barrier body A, B or released from it.

In order to allow the simplest and most reliable connection between the guide beam 19 and the barrier bodies A, B, the core 26 of the barrier body A, B is provided with a corresponding accessory 26a which extends in the longitudinal direction of the body of barrier A, B and which can be surrounded by the legs 30a, 30b of the guide rail 19. In this way, a sliding location of the guide rail 19 on the barrier bodies A, B parallel to the subfloor 3 is possible.

Figure 9 shows a perspective view of the barrier of guide sleepers 1a in the region of the front sides 4a, 4b opposite in the strike 4, of the barrier bodies A, B. To facilitate the understanding of the design the region that otherwise, it covers the barrier bodies A, B, rather their heels 25a, 25b, has been shown transparent. In addition, the transition between the guide beam 19 and the barrier bodies A, B, namely its upper side 7, is also represented in a transparent manner, in this aspect it is evident that on its extreme sides the barrier bodies A, B they are closed in the first instance by the front sides 31a, 31b which extend orthogonally with respect to the longitudinal direction of the barrier bodies A, B. Between the front sides 4a, 4b of the barrier bodies A, B, link plates are extended perforated 32a, 32b, linking the front sides 31a, 31b with the front sides 4a, 4b and, therefore, together form a modular profile closed on four sides.

On the other hand, the guide stringers 19 opposite in the strike 5 also have coupling parts 33a, 33b at their end sides, which have a frame configuration. Between the opposite coupling pieces 33a, 33b of the guide beam 19 are also provided inclined front sides 21a, 21b of the guide beam 19.

As can be recognized in this case, the claw 18a is arranged in the region of the guide rail 19 of the first barrier body A. The same applies to the opening 18b corresponding to the claw 18a, which is also arranged in the guide rail 19 of the second barrier body B. This representation which serves to clarify can of course also be applied to the arrangement of the claw 18a and the opening 18b directly on the barrier bodies A, B when the guide beam 19 is dispensed with.

The claw 18a is made of flat iron, which contains an arm 18c that extends in the longitudinal direction of the barrier of guide sleepers 1a as well as a hook section 18d angled with respect to the arm. In this regard, the angled hook section 18d is curved with respect to the arm 18c and the claw 18a, so that in the closed position a1 represented herein, the claw penetrates the opening 18b.

Inside the guide beam 19 disposed within the first barrier body A, a blocking element 34 is disposed, which at least by sections can be moved through the front sides 21a, 21b which in this case in the closed position a1 They are opposite each other. The blocking element 34 is connected to an electromechanical drive 36 by means of a connecting frame 35 arranged around the tension bar 20. In this way, it is possible to move the blocking element 34 by the mechanical drive 36 in the longitudinal direction of guide rail 19.

Assuming that the barrier bodies are provided with these guide stringers 19 arranged, in such case said guide stringers 19 are component parts of the barrier bodies within the meaning of the invention. In this context

The front side 21b of a guide rail 19 is also considered as a component part of the front side 4b of the second barrier body B, such that also the front side 21a of a guide beam is component part of the front side 4a of the first barrier body A in the sense of the invention. In this way, it is possible, for example, to also arrange the movable locking element 34 as well as one of the barrier bodies A, B as well as, if available, in one of the guide stringers 19, so that the in the sense of the invention, it can be moved fundamentally at least by sections on the front sides 4a, 4b.

In addition, it appears from Figure 9 that the mounting legs 28 are connected by a crossbar 37 with the first barrier body A. However, although the second barrier body also has a crossbar 37, it is not connected with mounting legs 28, which in any case the second barrier body B is stationary and in case it is fixed by the foundation not shown here.

Figure 10 shows the connection, already represented in Figure 9, of the barrier of guide sleepers 1a in the region of the barrier bodies A, B, opposite with their front sides 4a, 4b, as a cutout in a side view . In this case it is evident that the barrier bodies A, B have additional coupling means 38 that can be coupled together. The coupling means 38 have been implemented in the region of the lower side 2 on the front sides 4a, 4b. One of the coupling means 38 encompasses an ear 39 disposed on the first front side 4a, while the other coupling means 38 has an insert pocket 40 arranged on the second front side 4b. The ear 39 is oriented at right angles to the upper side 7 of the first and second barrier body A, B. In the closed position a1, shown here, the ears 39 and the insert pocket 40 are placed in a reciprocal contact.

As can be seen, the claw 18a has an opening 18e in its bent hook section 18d. This embodiment is necessary if the claw 18 a and the locking element 34 are arranged at least by regions in a position of mutual contact. The opening 18e of the hook section 18d serves this case to accommodate the locking element 34 in its forward position. In this way, additional security is obtained between both barrier bodies A, B in that the first barrier body A is screwed by the locking element 34 with both the second front side 4b and / or with the front side 21b as well as with angled hook section 18d.

Figure 11 illustrates the structure of the coupling means 38 in the form of a cutout of Figure 10. The insert pocket 40 is formed by an impact plate 41, which by means of a floor core 42 is attached to the second side front 4b. While the floor core 42 extends parallel to the subfloor 3, more precisely towards the lower side 2 of the barrier bodies, A, B, the impact plate 41 is oriented at right angles to the upper side 7 as well as with with respect to the lower side 2. Basically, the ear 39 and the impact plate 41 can also be inclined in a range of 0.1 to 5 ° in relation to the upper side 7 of the barrier bodies A, B in order to facilitate the reciprocal coupling. As shown, in this case the ear 39 constitutes a one-piece component part of the first front side 4a.

Already in Figure 10 the arrangement of a coupling plate 42a follows. The coupling plate 42a is arranged in the second barrier body B, more specifically in the region of its lower side. 2. In this regard, the coupling plate 42a protrudes above its second front side 4b, where in the closed position a1 passes partially below the first barrier body A.

With a view to Figure 11, it can be seen that the coupling plate 42a can be arranged in the form of an extension of the floor core 42 in the region of the insert pocket 40. In this case it is a flexing part, of which the second front side 4b and the floor core 42 are formed as well as the impact plate 41. In the present configuration, the coupling plate 42a is connected so that the continuity of the material is ensured, with the insert pocket 40. Of course, in a manner not shown in detail herein, the coupling plate 42a can be connected to other regions of the insert pocket 40. In this way, the insert pocket 40 can be arranged at least by regions on the plate coupling 42a.

In Figure 12, an alternative configuration of the coupling plate 42a is shown, which in this case is a component part of a single piece of a single material, of the floor core 42. In other words, in this case the second front side 4b and the coupling plate 42a are made of a flexed part in common, while instead the floor core 42 is formed by a region of the coupling plate 42a. In this case, the floor core 42 is delimited by the impact plate 41, which in this case is orthogonally arranged on the coupling plate 42a. As for the connection of the impact plate 41 with the coupling plate 42a, it is preferably an integral joint.

An additional detail of Figure 10 is shown in Figure 13, showing the free end region of the coupling plate 42a. In this view it is evident that the coupling plate 42a comprises at least one housing hole 42b. On the contrary, the first barrier body A, shown in a slightly elevated position, has at least one leg 42c on its lower side 2. The housing opening 42b and the leg 42c are configured so that they correspond to each other. In this way, the leg 42c and the housing opening 42b in the closed position a1 of the guide crossbar barrier 1, 1a, are at least partially coupled to each other. In the present case, the leg 42c is connected by means of a core 42d to the first barrier body A. In this regard, the core 42d extends in a manner that is not shown transversely with respect to the longitudinal direction of the barrier of

guide sleepers 1, 1a.

Figure 14 shows a view of the second barrier body B with a view of its second front side 4b. As can be seen, the impact plate 41 prepositioned on the front side 4b has a shape adapted to the development of the heels 25a, 25b, as well as the deflections 26a, 26b. In addition, additional coupling means 38 can be observed that are arranged in the form of recesses 43 in the floor core 42. On the other hand, the impact plate 41 is separated by two pointed vertical souls 44 with respect to the second front side 4b. In other words, the vertical souls 44 represented in Figure 11 are located between the impact plate 41 and the second front side 4b, where in this case the recognition capacity of the recesses 43 and the vertical souls 44 can be attributed to the fact that for greater clarity the impact plate 41 is shown transparent.

Figure 15 shows a plan view on the second barrier body B. In this view, the vertical souls 44 are again evident by means of which the impact plate 41 is separated with respect to the second front side 4b. In addition, the coupling plate 42a can be recognized as an extension on the lower side of the second barrier body. Again, this view allows to observe the housing openings 42b arranged in the coupling plate 42a, of which in the present case there are two arranged. How can it be recognized, the housing openings 42b have a rectangular configuration, the housing openings 42b being rounded in the regions of their corners.

Figure 16 shows a view of the first front side 4a of the first barrier body A. Here it is evident that the ear 39 is formed by two grooves 45 separated from each other and extending parallel to each other from the first front side 4a. In addition, the first front side 4b has in the region of the curvatures 26a, 26b stump-shaped projections 46, which extend towards the lower side 2 of the first barrier body A. The projections 46 correspond to the recesses 43 shown in Figures 14 and 15, the projections 46 and the recesses 43 being provided for, the guide crossbar barrier 1, 1a being in the closed position a1, to be coupled to each other, at least partially.

Figure 17 shows in a perspective view the first front side 4b already represented in Figure 16. It can be clearly seen that the first front side 4a is curved with respect to the deflections 26a, 26b and with respect to the ear 39. In the closing position a1 of the guide sleeper barrier 1, 1a, the vertical souls 11 shown in Figure 11 are coupled with the grooves 45 of the first front side 4a, so as to reinforce the coupling between the barrier bodies A B.

Figure 18 shows the support arrangement 8 already represented in Figures 1 and 2 in a perspective view. To further illustrate the design of the support arrangement 8, it has been removed from the cover 23 indicated in Figures 4 and 5, while the removable transition cover 22 can still be observed. The barrier body A extends to an adapter unit 50 located on the side of the pivot bearing. The floor plate 17 has a limiter 47, which is arranged in the form of a flag plate on the floor plate 17 and from there extends from there over the edge in the direction of the transition cover 22.

The limiter 47 serves to laterally support the pivotable barrier body A in the closed position a1. This is implemented by making the limiter 47 be arranged at least on one side of the frame 15, which is linked to the first barrier body A. It is preferable that the limiter 47 is arranged on both sides of the frame 15 on the floor plate 17 in the plane of the lower side 2 of the body barriers A, B, so that a lateral support takes place on both sides. Therefore, the lateral support is removed at the moment when the first barrier body A is pivoted from its closed position a1 to the open position a2. In this case, the fixed frame 15 fixed to the column 16 pivots around the horizontal axis of rotation 10 and thereby is released from the side closure thanks to the limiter 47

Figure 19 shows a variant of the barrier of guide sleepers 1, 1a in the region of its support arrangement 8. For this purpose, the first barrier body A has a transverse plate 47a, which is arranged inside of the first barrier body A between its heels 25a, 25b. The transverse plate 47a extends transversely with respect to the longitudinal direction of the first barrier body A.

As can be seen, the transverse plate 47a has cuts 47b oriented towards the lower side 2 of the first barrier body A. The cuts 47b begin at an edge region oriented towards the lower side 2 of the transverse plate 47a and extend limitedly upwards . In the present case, two such cuts 47b are arranged at a distance from each other in the transverse plate 47a.

On the other hand, limiters 47c corresponding to the cuts 47b are fixed on the floor plate 17 of the support arrangement 8. The limiters 47c are made as flag plates erected on the floor plate 17 and extending in the first body of barrier A. It is preferable that the limiters 47a be joined in solidarity with the floor plate 17, for example by welding. In the representation of Figure 19 it is evident that the limiter 47c and the cuts 47b of the transverse plate 47a enter a coupling contact, as long as the first barrier body A is in the closed position a1. In this case, in the closing position a1 the limiters 47c are laterally surrounded in a manner not represented by the cuts 47b, at least partially.

As can be seen, in the first barrier body A there are two transverse plates 47a arranged in

guide 49 and the first barrier body A and the second barrier body B together, on which correspondingly individual guide beams 19 are arranged which are joined by the tension bars 20 with them.

As already shown in Figures 7 to 10, in both closed positions both barrier bodies A, B are supported on the subsoil 3 by means of their positioning legs 28. Instead, the guide sleepers 49 that are coupled to the bodies of barrier A, B in its longitudinal direction, are releasably connected by bolts 24a with the subfloor 3. A guide rail 19 applied to the first barrier body A has a maintenance flap 51 in the region of the strike 5, by means of which, if necessary, the electromechanical overcrowding 36 shown in Figures 9 and 10 can be accessed. In the region of the support arrangements 8a on the end sides of the barrier of guide sleepers 1b additional side cheeks 6c are arranged which of analogously to the side cheeks 6a, 6b in the region of the strike 5 between both barrier bodies A, B also serve to cover the gap between the guide sleepers 49 and the first sweeping body to A as well as the second barrier body B.

Figure 22 shows a view of the system for retaining vehicles 48a of Figure 21. In this view it is evident that the guide sleepers 49, as well as both barrier bodies A, B have lateral arms 26a, 26b, as shown with reference to both barrier bodies A, B in Figures 7 and 8 as well as 14 to 16. In this regard, those of the bolts 24a that link the guide sleepers 49 with the subfloor 3 are passed on both sides of the sleepers of guide 49 by means of its lateral arms 26a, 26b.

Figure 23 shows a system for retaining vehicles 48a of Figures 21 and 22 in a perspective view of their closing position a1. For a better understanding of the support arrangements 8a of both barrier bodies A, B as well as their configuration in the region of the strike 5 both barrier bodies A, B as well as the guide beam 19 have been represented transparently by regions in shape of cuts. In this way, the view inside the system is released to retain vehicles 48a. The respective contents are subject to the following Fragments 24 and 25.

Figure 24 shows a cut-out of the left support arrangement 8a in the representations of Figure 23, in a partially transparent representation. As explained with reference to Figures 1 and 2 and also 18 of the guide crossbar barriers 1, 1a, also the support arrangement 8a shown here of the alternative guide crossbar barrier 1b has a horizontal rotation axis 10 , around which the second barrier body B can pivot vertically. The design shown here also applies correspondingly to the support arrangement 8a of the first barrier body A shown in Figure 23. As can be recognized, there is also a strut 16 which supports the horizontal rotation axis 10, while instead the second barrier body B is connected to a rotating element 52. Said rotating element 52 is crossed by the horizontal rotation axis 10 which is supported on the strut 16. In this regard , the connection between the rotating element 52 and the second barrier body B has been carried out in such a way that a rotation of the rotating element 52 about the axis of rotation ion 10 has the effect of vertical pivoting of the second barrier body B around the horizontal axis of rotation 10. In other words, for this purpose the turning element 52 and the second barrier body B are linked to each other with a stiffness to flexion

As can be recognized by observing the guide cross member 49 of Figure 24, it also has at least one maintenance hatch 51a, which, if necessary, can be opened, for example, by releasable means of attachment. Behind this maintenance hatch 51a there may be a joint, not shown in greater detail between the turning element 52 and a suitable drive, whose articulated joint is thus accessible by opening the maintenance hatch 51a for any maintenance work or service

In Figure 25, a cutout of the junction of the closed guide rail barrier 1b can be seen in the region of the opposite barrier bodies A, B with their front sides 4a, 4b. Through the partially transparent representation, the view towards the interior is released, for which in this regard reference is made to the explanations corresponding to Figure 10.

In addition, a side plate 53 adapted to the side cheek 6a can be recognized, which is now adapted to the second barrier body B. The side plate 53 is arranged flat on the side heel 25b of the second barrier body B. It is preferable that the side plate 53 is joined in a solidary manner at least in sections with the side heel 25b, for example by means of a welding seam. The side plate 53 adapted in its thickness orthogonally with respect to the area of the side heel 25b on the side cheek 6a is provided to protect the side cheek 6a against deflection in case of receiving a collision impact. For this, both the side cheeks 6a and also the side plate 53 with its outer areas are parallel to the heel 25b, at least approximately the same height. In this way, a possible penetration of a vehicle that collides with the system to retain vehicles 48a is prevented, especially in the case of an impact with a flat angle on the barrier of guide sleepers 1b.

Figures 26 and 27 show the system for retaining closed vehicles 48a in Figure 23 with barrier bodies 1b open. In the case of the present open position a2 the first barrier body is pivoted in the first instance

A, followed by the second barrier body B. To return to the closed position a1 represented in Figure 23, this process takes place in an inverse sequence, in which in the first instance the second barrier body B followed by the second Barrier body B is pivoted back followed by the second barrier body A to the subfloor 3.

This sequence is necessary due to the arrangement of the side cheeks 6a, 6b, which in the closing position a1 cover the second barrier body B in the region of its front side 4b as well as in this case also in the region of the front side 21b of the guide beam 19 arranged in the second barrier body B, at least by regions.

In addition, this sequence is necessary in the first instance to allow the deposition of the coupling plate 42a which in the closing position a1 passes through regions below the barrier body A, of the second barrier body B on the subsoil B.

Observing Figure 26, this view again provides a view on the lower side 2 of the second barrier body B, showing the crossbars 37, already represented in Figures 9 and 10, with the support legs 28 arranged therein. As can be recognized, the crossbars 37 extend transversely with respect to the longitudinal direction of the second barrier body B. Said crossbars 37 together with the positioning legs 28 arranged therein, are shown in a manner not detailed in Figure 27 available in particular in the first barrier body A on its lower side 2.

Although the positioning legs 28 allow a deposition of both barrier bodies A, B in the subfloor 3 and the lifting of both barrier bodies A, B from the subsoil, the guide sleepers 49 that extend in both support arrangements 8a from the barrier of guide sleepers 1b, are firmly connected by bolts 24a to the subfloor 3.

In both Figure 26 and also in Figure 27, the floor plate 17 indicated in Figure 19 can be recognized again with the limiters 47c arranged thereon.

Figure 28 shows a view of the support arrangements 8a of Figures 26 and 27. Due to the support arrangement 8a of similar design arranged both in the first barrier body A in Figure 27 and also in the second barrier body B in Figure 26, the support arrangement 8a shown in Figure 28 again represents its corresponding design in a partially transparent representation.

As can be seen in Figure 24, in this case the corresponding barrier body A, B is coupled to a rotation element 52. In this view it is evident that the rotation element 52 has an arm in the form of a lever arm 54 extending from the horizontal rotation axis 10. In this regard, the lever arm 54 and the longitudinal direction of the corresponding barrier body A, B cover an angle c3 that is less than 90 °.

In this case the angle c3 has been implemented with an angle of 45 °. In an extreme region, opposite the horizontal rotation axis 10, of the lever arm 54 it has an incident point 55 for a drive not shown here.

As for the said drive, it is preferably a linear drive, which is articulated to the lever arm 54 by means of the incident point 55, where by means of a limited rotation of the lever arm 54 about the horizontal rotation axis 10 the corresponding barrier body A, B is also pivoted about the axis of rotation 10. In this case said drive, not shown in detail, is preferably accessible through the maintenance flaps 51.

As a result, a barrier of sleepers of modular guide and light structure 1, 1a, 1b is indicated as a component part of a system for retaining vehicles 48, 48a, which in particular in its region of connection allows sufficient coupling, to be used for high retention levels.
