Description

The invention relates to a crash barrier for integration in a vehicle restraint system on a traffic route according to the preamble of claim 1 and a vehicle restraint system with such a threshold barrier according to claim 10.

In addition to the purely optical clarification of the traffic management by means of guide devices are used in particular passive protective devices to stop a departing from the designated lane vehicle. In the form of mobile or stationary vehicle restraint systems crashes and any collision with oncoming traffic are thus effectively prevented.

In contrast, especially in emergency situations, a rapid section opening within these vehicle restraint systems is required to allow, for example, an unimpeded fire or ambulance passage. Since these vehicle restraint systems constitute a physical separation and thus a boundary that otherwise would not otherwise be traversable with a vehicle, corresponding devices are necessary for this purpose.

The vehicle restraint systems formed mostly by releasably juxtaposed barriers made of concrete or metal have for this purpose pivotable sections in order to cancel the otherwise desired barrier effect, if necessary, at least in sections. For this purpose, individual Leitschwellenabschnitte are formed as a Leitschwellenschranke, wherein they are fixed on one side about a rotation axis and thus are pivotable about them from a closed position to an open position. Another opening principle of a Leitschwellenschranke discloses the EP 2 418 324 A1 , In this case, the lowerable guard rail assembly is retractable and retractable by a double scissors gear and can be lowered in the retracted state so far that it can be driven over by vehicles.

The DE 10 2008 016 837 A1 discloses a threshold barrier for integration into a stationary vehicle restraint system on a traffic route. For this purpose, the barrier barrier comprises a barrier body which extends in its longitudinal direction and which is arranged so as to be horizontally pivotable about a vertical axis of rotation at an end bearing area. Furthermore, the barrier body on its end remote from the storage area on a coupling means, via which the barrier body can be coupled with a coupling means corresponding to the portion of the vehicle restraint system.

From the DE 20 2004 005 084 U1 is a guardrail as part of a crash barrier arrangement forth, which is mounted end over a horizontal axis of rotation. Upon release of a lock, the guardrail is thus vertically pivotable, if necessary, to allow passage of the crash barrier arrangement.

From the CH 460 845 A a threshold barrier for integration into a vehicle restraint system on a traffic route is known. This comprises a first barrier body with a first end face and a second barrier body, which has a second end face corresponding to the first end face. In this case, the two barrier body mutually engageable coupling means in the form of holes and bolts. At one of the barrier body remote from the end face end bearing assembly is provided, on which the barrier body is mounted on a horizontal axis of rotation. As a result, the barrier body is vertically pivotable from a closed position in an open position. A befindlicher in the closed position between the two end faces of the barrier body gap is bridged at least in some areas by at least one side cheek, which is arranged on one of the barrier body.

The systems known in this way have basically proven themselves in practice. In order to obtain a sufficiently large opening during horizontal pivoting of the designed for high impact loads Leitschwellschranke, a corresponding length of the base body used is required. Especially in confined spaces so sometimes only small opening widths can be realized. Depending on local circumstances, this can lead to a system that is sufficient in width not being able to be realized in the required range. In contrast, the vertically pivotable guardrail is an independent of the lateral space system, which is used by design for smaller expected impact loads its use.

The older, post-published German application 10 2011 053 263.3 shows a high collision loads safely receiving solution for a vertically pivotable Leitschwellenschranke, which serves as part of a stationary vehicle restraint system. The Leitschwellenschranke has a first and a second barrier body, which have mutually engageable coupling means. One of the coupling means in this case comprises a front side of the first barrier body arranged tab and pin-like projections, whereas the other coupling means arranged a front side of the second barrier body Pocket has a bottom web, which has recesses.

In a closed position of the Leitschwellenschranke the tab with the insertion pocket and the projections with the recesses at least partially engageable with each other. To open the Leitschwellenschranke at least one of the two barrier body remote from the respective end face end bearing assembly is provided, on which the corresponding barrier body is mounted on a horizontal axis of rotation and so can be pivoted vertically as required from a closed position to an open position. The gap located in the closed position between the two end faces of the barrier body is at least partially bridged by at least one side cheek, which is fixed to one of the barrier body.

Depending on the area of application and in particular at high impact loads, correspondingly high safety requirements in accordance with DIN EN 1317 ("Restraint Systems on Roads") must be addressed to the design of such vehicle restraint systems. Depending on the opening width, the openable sections in particular constitute a long lever arm whose reaction to an impact causes measures to be taken which differ from the rest of the main barrier strip in order to absorb the resulting forces. In other words, due to the pivotability increased demands on the movable connections and in particular the necessary coupling of the free end are directed to the rest of the vehicle restraint system, which constitute a potential vulnerability.

Against this background, in particular the connection between the pivotable section and the stationary fixed elements still offers room for improvement.

The present invention is based on the object, a vertically pivotable Leitschwellenschranke the aforementioned type and a vehicle restraint system with such a threshold barrier further to improve, so that the Leitschwellenschranke located in its closed position even at very high, in particular acting on her vertically pivotable end impact loads has fail-safe coupling and almost invariable storage of its free end, especially within a stationary vehicle restraint system.

The solution to this problem consists according to the invention in a Leitschwellenschranke for integration into a vehicle restraint system with the features of claim 1 and in a vehicle restraint system for a traffic route with the features of claim 10.

Hereinafter, a Leitschwellenschranke for integration into a vehicle restraint system on a traffic route is shown below, which comprises a first barrier body with a first end face and a second barrier body with a second end face corresponding to the first end side. The barrier bodies have mutually engageable coupling means. One of the coupling means comprises a tab arranged on the first end side and pin-like projections, wherein the correspondingly different coupling means has an insertion pocket arranged on the second end face with a bottom web. The bottom web of the insertion pocket further has at least one recess, preferably a plurality of recesses. In a closed position of the Leitschwellenschranke both the tab with the insertion pocket and the projections with the one or more recesses are at least partially engageable with each other.

As an advantageous embodiment, the projections and the recesses are each arranged in the outer edge regions of the insertion pocket and the front side. In this way, a stable connection between the barrier bodies is ensured, which also holds a high bending load perpendicular to the pivot axis of the barrier body.

Furthermore, at least one of the two barrier body remote from the end face end bearing assembly is provided, on which this barrier body is arranged vertically pivotable about a horizontal axis of rotation. In this way, the barrier body is vertically displaceable from a closed position to an open position.

A gap located between the two end faces lying opposite in the closed position is bridged over at least in places by at least one side cheek. In a preferred embodiment, two side cheeks may be provided, which at least partially surround the gap between the two end sides from both sides bridging. The at least one side cheek is arranged on the first barrier body or on the second barrier body.

The side wall represents a stop against which the other barrier body can be supported. Of course, the, the side cheek having barrier body can be supported against the other barrier body. Especially horizontally on the Barrier-directed impact loads can be taken so initially on one of the barrier body, with its free end can support at least one side cheek against the free end of the other barrier body. By transferring the loads between the barrier bodies on the side wall each free end of the barrier body is fixed in its position.

In particular, with two side cheeks, these can be arranged simultaneously either on the first barrier body or on the second barrier body, wherein in each case one of the two side cheeks can be arranged on the first barrier body, while the other side cheek is arranged on the second barrier body. Even if the side walls each arranged on one of the two barrier bodies can be arranged on a common side of the two barrier bodies, these are preferably connected to one of the barrier bodies only on one side.

Due to the two-sided arrangement of the side cheeks in the region of the opposite end faces of the barrier body whose free ends are stabilized against each other. In particular, in one embodiment, where both barrier body are mutually vertically pivotable, the side cheeks serve to transmit a possible moment across the gap between the barrier bodies.

According to the invention, the first barrier body has a claw which is arranged at its free end and which corresponds with an opening. Said opening is part of the second barrier body, wherein the opening is arranged in an upper side of the second barrier body. The claw and the opening are configured to be engaged by a vertical pivotal movement of one of the barrier bodies. In this case, the claw of the first barrier body engages in the closed position of the Leitschwellenschranke at least partially in the opening of the second barrier body. In contrast, the engagement of the claw in the opening in the furnace position of the barrier barrier is canceled.

Depending on the requirement, the formation of the claw may be such that with a limited vertical pivoting of the barrier body, an engagement of the claw in the opening continues.

For this purpose, the claw may have a length adapted to the respective requirements hook portion, which dives correspondingly deep into the opening of the second barrier body. In this way, even with a limited lifting of the first barrier body, for example by an impact continues to be given a holding connection through the combination of claw and opening between the two barrier bodies.

The particular advantage of the claw in combination with the opening is that this not only horizontally directed impact loads directed horizontally to the barrier body can be forwarded, but that the claw forms a tension band and / or pressure band between the opposing barrier bodies. In this way, loads extending in the longitudinal direction of the one barrier body can also be forwarded via the claw to the respective other barrier body. For this purpose, the opening is preferably formed so that in particular the angled hook portion extends in the closed position of the Leitschwellenschranke as close as possible to an edge of the opening. In this way, only a small longitudinal offset or transverse offset between the barrier bodies is required to activate the connection thus created.

In a further embodiment, the claw and the opening can also be matched to one another in such a way that, in the closed position of the threshold barrier, they permanently have a contact area between them which adjusts at least in regions. Depending on the requirement, the coupling thus created between the opening and the claw can be made in a force-locking and / or form-fitting manner.

The claw has a substantially horizontal arm, wherein the hook portion is angled relative to the boom. In this case, the boom and hook section enclose an angle of 70 ° to 100 ° between them, preferably 90 °. In order to obtain a connection which is as stable as possible, also in the horizontal plane, transversely to the longitudinal direction of the barrier barrier, the boom of the claw preferably has a width exceeding its height and extending in a horizontal plane. As a result of this embodiment, the moment of resistance of the claw about the strong axle formed in this way is significantly increased with respect to a horizontal impact load, so that a deformation-poor and secure coupling between the two barrier bodies is achieved even during the impact.

Advantageous developments of the basic concept of the invention are the subject of the dependent claims 2 to 9.

After that, the second barrier body may have a coupling plate arranged on its underside and protruding beyond its second end side. The coupling plate may be, for example, the extension of a bottom plate of the second barrier body. Of course, the coupling plate can also be arranged as a single component in the region of the plane of the underside of the second barrier body at this.

Depending on the configuration, the coupling plate may be connected to the barrier body, for example via detachable connection means. In combination with the arrangement of slotted holes so any deviations from the planned distance between the opposing barrier bodies can be compensated by adjusting the position of the coupling plate on site. Preferably, the coupling plate is integrally connected to the second barrier body, for example by means of a weld or over welding points.

Since the coupling plate is projecting beyond the second end face of the second barrier body, it can at least partially engage under the first barrier body in the closed position of the barrier threshold. A possible height offset of the thus at least partially resting on the coupling plate first barrier body can be compensated for example by an offset or a jump in the cross-section of the coupling plate. In contrast, the first barrier body may also have a corresponding recess or an offset on its underside in the region of its free end to accommodate the thickness of the coupling plate in the closed position of the Leitschwellenschranke.

Depending on the configuration, the coupling plate can be connected to the second barrier body either by means of releasable connection means or by material engagement, for example by welding. The advantage of using detachable connection means is the fact that any tolerances on site can be compensated thereby. In particular, in combination with the arrangement of oblong holes so any deviations in the position of the immediately opposite barrier body can be compensated. Furthermore, any damage to the coupling plate requires an exchange, which only requires their easy removal when using releasable connection means.

In order to enable a coupling of the immediately opposite barrier body by means of the coupling plate, this has at least one receiving opening, wherein the first barrier body has at least one foot disposed thereon on its underside. Preferably, a plurality of receiving openings are provided in the coupling plate, whereas the first barrier body also has several feet. The at least one receiving opening and the at least one foot are provided so that they are at least partially engageable with each other in the closed position of the Leitschwellenschranke. In an alternative embodiment, of course, the coupling plate itself may have at least one such foot, whereas the first barrier body has at least one corresponding receiving opening on its underside.

Preferably, at least two receiving openings and two feet are provided, which are arranged at a distance from one another perpendicular to the longitudinal extension of the barrier threshold. By this arrangement, a resulting, for example, from an impact moment across the gap between the two end faces away through the coupling plate on the other barrier body is transferable. Furthermore, so acting in the longitudinal direction of the barrier barrier tensile and / or compressive loads are transferable.

Depending on the desired interaction with the side wall and the other coupling means, the receiving opening and the foot can be coordinated so that they allow for a possible deflection of a barrier body either a direct or later occurring force transmission. This interaction is largely determined by the vote of the foot and the receiving opening in their respective forms each other. Thus, for example, the receiving opening directly has a peripheral contact with the foot in the closed position of the Leitschwellenschranke. In contrast, the dimensions of the foot can recede from the dimensions of the receiving opening so that the foot has a corresponding clearance within the receiving opening. In order to enable force transmission and reception in this case, a deflection of at least one barrier body is first necessary in order to bring the foot and the receiving opening into edge-side contact.

The foot and / or the receiving opening may for example have a round or oval, in particular circular shape. In an advantageous embodiment, the foot and / or the receiving opening may be polygonal. For example, a quadrangular or rectangular configuration allows the largest possible contact surface between an edge region of the opening and the foot. In this way, the occurring forces can be transmitted over the largest possible area. Any radii or bevels between the edge areas converging in the corners reduce a possible gap or notch effect during a load. The larger the transfer area between the receiving opening and the foot, the lower the respective stress loads.

In one development, the foot and / or the receiving opening can also have an inclined position of at least one of its edge regions. Of course, the receiving opening and / or the foot can also be designed as a whole conical. As a result of the at least one inclined edge region, when the respective barrier body is pivoted into the closed position, an immediate positive and / or frictional connection is made possible between the receiving opening and the foot.

The insertion pocket can be formed by a front-side impact plate, which is spaced over two vertical webs from the second end face. In order to allow the simplest possible engagement, the impact plate is preferably aligned at right angles to the top of the second barrier body.

The coupling means thus enable automatic locking of the barrier body in the closed position, which is solved simultaneously when pivoting in the open position. The tongue-like tab engages when pivoting in the closed position behind an undercut of the insert pocket. Depending on the configuration of the coupling means, high normal forces can be transmitted between the barrier bodies virtually free of play.

In an advantageous development of the bottom web may be an integral material integral part of the coupling plate. As a result, only the arrangement of the coupling plate projecting beyond the second end face on the second barrier body is necessary, on which the insertion pocket of the one coupling means as well as the at least one receiving opening and / or the at least one foot are arranged. Of course, the bottom web and the coupling plate can also be coupled together by means of releasable connecting means or by welding.

Preferably, a displaceable locking element is arranged in or on one of the barrier body, which is at least partially displaceable through the opposite in the closed position end sides. In this way, the barrier body can be fixed in the closed position via the locking element with each other. In addition to the supporting effect of the side cheeks in transverse loads, for example in an impact, in particular an undesired pivoting of the barrier body from its closed position is effectively prevented by the sliding locking element. Since the invention provides both a manual, more mechanical, as well as otherwise driven pivoting of the barrier body, the unauthorized opening of the Leitschwellenschranke is also prevented by their pivoting into the open position by the sliding locking element. In this case, the displaceable locking element may have an access barrier, for example a closure which allows only authorized persons whose unlocking.

The first end side and an upper side of the first barrier body may include an inclination angle of less than 90 ° between them. Also, the second end face and an underside of the second barrier body include an inclination angle of less than 90 ° between them. The horizontal axis of rotation is arranged in a first alternative embodiment above the top of the barrier body. As a result, an ideal position and a low-play contact between the end faces of the barrier body to each other allows. In a second alternative embodiment, the horizontal axis of rotation can also be arranged in the plane of the upper side of the barrier body. Here, too, results in the same positive effect. In contrast to a arranged on the underside of the barrier body horizontal axis of rotation according to the invention no support of the pivotable barrier body on its upper side necessary to secure it against possible tilting or deflection during an impact. By as massive a configuration of the bearing assembly in combination with an arranged in the top of the barrier body axis of rotation occurring in an impact transverse forces are transmitted safely and without inclining the top of the barrier body directly into the bearing assembly and thus into the ground.

The particular advantage consists in the combination of the inclined end faces and the connecting the barrier body coupling means together with the coupling plate and the at least one side cheek. If only a one-sided impact of a vehicle on the barrier body is possible, only a single side cheek can be arranged on the side of the possible impact. Preferably, the threshold barrier according to the invention is arranged centrally as a structural separation between two traffic lanes, so that a possible impact can take place from both sides of the barrier barrier. In these cases, at least two side cheeks are preferably arranged, which are arranged on the opposite sides of the barrier body.

In particular, at identical inclination angles parallel to each other inclined end sides allow a play-free contact between the barrier bodies. In combination with the coupling means and the side walls surrounding the barrier body side is thus in the closed position an almost rigid connection allows, which can be solved easily if necessary.

In the event of an impact, in particular the coupling means and the coupling plate in conjunction with the receiving opening and the foot serve to safely absorb the tensile forces occurring as a result of bending or evasion as normal forces between the barrier bodies. In addition, the transverse forces occurring are transmitted securely parallel to the axis of rotation of the pivotable barrier body through the side walls between the first and the second barrier body. Due to the small gap between the preferably parallel to each other in the closed position end faces the required coupling means and the coupling plate and the side cheek can be made short. As a result, their burden is reduced by bending moments occurring.

Due to the low-backlash connection between the barrier bodies both the coupling means and the side cheeks and the coupling plate with receiving opening and foot are activated as early as possible in an impact to transmit the forces occurring. In other words, no major deflection of the pivotable barrier body or both barrier body is necessary to initiate the holding effect of the coupling means and the side cheeks.

The angle of inclination between the end faces can be from 65 ° to 85 °. Preferably, the inclination angle has a value of 70 ° to 80 °. In a particularly preferred embodiment, the inclination angle is 75 °.

The largest preferred angle of inclination results from the position of the horizontal axis of rotation and the transition region of the inclined end face to the underside of the top side of the first barrier body. In this case, the transition point between the first end face and the underside of the first barrier body describes the position of a tilt axis of the end face extending parallel to the axis of rotation, wherein the axis of rotation and the tilt axis span a plane between them. The included between this level and the top of the first barrier body angle corresponds in its subtraction of 180 ° the largest preferred inclination angle. In compliance with this geometry, an ideal parallel course of opposite in the closed position end faces to each other is possible at zweckentsprechendem gap, more closely spaced. The distance takes into account the weather- or temperature-related expansion processes of the material of the barrier body, so that at any time opening and closing of the barriers is guaranteed.

In a preferred embodiment, the bearing arrangement has a base plate with at least one limiter. The barrier body is thus laterally supported in the closed position by the limiter. In particular, in combination with a arranged in the top of the barrier body horizontal axis of rotation of the barrier body is thus effectively supported in the closed position in the plane of its underside before a possible avoidance in an impact. If the guideway barrier according to the invention is arranged between traffic lanes traveled on both sides, the bearing arrangement advantageously has one, preferably two limiters, wherein the limiters can each be arranged on both sides of the barrier body on the bottom plate of the bearing arrangement. The limiter can be configured differently and executed, for example, as a pin or stop body.

In an advantageous embodiment of the first and / or the second barrier body in the region of the bearing assembly have a cross plate. Said transverse plate extends perpendicular to the longitudinal direction of the respective barrier body. Furthermore, the cross-plate can be designed so that this has at least one corresponding to the limiter cutout. Here, the respective limiter is not fixed to the side of a barrier body, but is located below the barrier body on the bottom plate of the bearing assembly. Of course, said bottom plate may also be fixed independently of the bearing arrangement directly on a respective substrate. In combination with the arranged inside the barrier body cross-plate whose at least one cutout in the closed position of the Leitschwellenschranke the limiter surround at least partially.

Preferably, the limiter is arranged in the form of a flag plate on the bottom plate, which extends away from the bottom plate perpendicular to the cross plate and thus into the respective barrier body.

Although the limiter may have a pin shape, this is preferably formed as a plate, wherein the limiter extends in a plate shape in a plane parallel to the longitudinal direction of the Leitschwellenschranke. In this way, the inevitably resulting pivoting movement of the cutout on a circular path around the horizontal axis of rotation of the bearing assembly around be configured so that the cutout of the transverse plate is pushed from one edge of the limiter starting over this.

By extending in the longitudinal direction of the barrier barrier width of the plate-shaped limiter ensures that the holding effect in relation to a transverse load of the barrier body is still given, if the barrier body is lifted from the closed position limited, for example, by an impact. So even with a heavy impact in combination with a limited lifting of the barrier body, the holding effect of the limiter is possible.

In an alternative embodiment, the invention provides that both barrier body have a side facing away from their end faces end bearing assembly with a horizontal axis of rotation. According to the invention thus both barrier body can be pivoted vertically from a closed position to an open position. As a result, two opposite each other in mutual extension and mutually pivotable barrier body are present, which allow, despite a short construction time together the largest possible opening width. As a result, the barrier body may be formed identical except for the arrangement of the coupling means and the side cheeks and the respective direction of rotation of the end faces.

Advantageously, a guide rail, in particular a plurality of guide rails, are provided, which are arranged above the first barrier body. In principle, a guide bar can also be arranged above the second barrier body. Above means in this case placed directly on the barrier body or spaced by appropriate arrangements. While the first barrier body and / or the second barrier body form / form the basic structure, the guide rail initially leads to a structural increase and stiffening of the system. Depending on the intended use and the required retention level, it is also possible to provide a plurality of, in particular two guide bars arranged one above the other. Of course, additional guard rails can be mounted on the Leitholmen, which then extend in the longitudinal direction.

The guide rails can be connected via tie rods with the barrier bodies. For this purpose, the tension rods are braced with the abutments provided inside or at the barrier bodies. The tension rods are preferably threaded rods which have at least one section with a thread. About the thread, the tension rod can be braced by its rotation with the abutment. Preferably, it is an external thread, in particular a coarse thread. The abutment is equipped for this purpose with a corresponding internal thread. In this way, the guide rail and the barrier body are pulled against each other and tightened by turning the tie rod.

The actuation of the tension rod is preferably carried out from an upper side of the Leitholms ago. For this purpose, the tension rod may have a rod end to which a corresponding handle for rotating the tension rod can be attached. Advantageously, the tension rod passes through the guide bar completely with its upper end.

In principle, it is also possible to materially connect the guide rails or similar attachments with the barrier body, in particular to be welded.

With respect to the displaceable locking element is provided that this is both manually and automatically displaced. In the latter case, this can be controlled for example via a centralized or decentralized control. Preferably, the locking element is displaced by means of an electromechanical drive. In principle, the pivotable barrier body can be pivoted via a corresponding drive, for example hydraulically, pneumatically or electromechanically. Preferably then also its control via the same centralized or decentralized control, which is provided for the control of the locking element.

Preferably, the barrier body with the locking element opposite end face on an opening. In the closed position of the barrier body, the locking element is at least partially displaceable into this opening. Here, the locking element end, for example, have a conical configuration, while the opening is circular. In this way, an almost play-free connection between the conical part of the locking element and the opening can be created, which improves the mutual connection between the base body and the counterpart.

In an alternative embodiment, the claw may have such an opening with respect to its angled hook portion. In this way, the locking element can be guided in the closed position of the barrier body at least in sections through the openings of the end face and the hook portion. The particular advantage is that this ensures an additional securing of the barrier body from any lifting during an impact.

As a result, a threshold barrier is shown, which in its closed position, even at high impact loads a safe and durable Position fixation ensures their free end. By connecting a plurality of holding components in the form of coupling means, side cheek, bottom limiter and the coupling plate in combination with the receiving opening and the foot and the displaceable locking element ensures that the respective barrier body with respect to its ends with a high reliability and almost invariable storage in Closed position is set. In this case, at least some of the holding components are formed so that the connection is still active even if one of the barrier body is limited raised from the closed position.

In particular, the combination of inclined and mutually parallel end faces allows large-area contact between or the free ends of the barrier body, closer between the end faces, which advantageously allows a large-scale power transmission. Together with the coupling means and the side cheeks thus results in an almost rigid connection between the barrier bodies, which has a positive effect on the possible to be achieved containment levels.

In the context of the invention, a vehicle restraint system for a traffic route is shown, which has releasably connected to each other Leitschwellen and a Leitschwellenschranke according to the previous versions. Preferably, the Leitschwellen analogous to the Leitschwellenschranken formed coupling means and / or receiving openings and feet, whereby these are easily interchangeable and coupled in the form of a modular principle. Also, the fixed barrier body may have at its end opposite the end of a corresponding with the coupling means of the baffles coupling means to be integrated within the vehicle restraint system. The same applies to the design of the coupling plate (receiving opening, foot). Furthermore, the bearing arrangement may also have a corresponding coupling means on its region facing the barrier baffles, which corresponds to the coupling means of the baffles, so that the baffles can also be brought into engagement with the bearing arrangement.

In a preferred embodiment, the barrier body in its cross section correspond to the cross section of the baffles. As a result, at least in the closed position, an optically virtually seamless transition between the baffles and the barrier body is made possible. Depending on the configuration, the bearing arrangement can also be adapted to the cross section of the guide thresholds. If the bearing arrangement has deviating dimensions from the cross section of the guide thresholds, the transitions between the bearing arrangement and the guide thresholds preferably have smoothed or rounded surface transitions in order to form as little as possible no protruding areas. The aim is to forward a colliding with the vehicle restraint system, which strikes the vehicle restraint system in particular at an acute angle, with as little burden for the occupant and possibly stop, without risking a collision with any protruding areas of the vehicle restraint system.

In the present case, a vehicle restraint system for a traffic route is shown, which is composed of easily adjoining traffic thresholds and at least one guidewell barrier. The bottom side starting and perpendicular to the course of the traffic route upwardly extending barriers and barrier body allow a self-contained and continuous barrier, which can be opened locally if necessary by pivoting at least one barrier body. In particular, the configuration of the mutually corresponding end faces of the barrier body allow the use of the Leitschwellenschranke even at high retention levels required.

1 shows a side view of a Leitschwellenschranke invention 1 , The threshold barrier 1 comprises a first barrier body A and a second barrier body B, which with their undersides 2 bottom side on a substrate shown in a sectional view 3 a traffic route not shown are arranged. The two barriers A, B are located with their faces 4a . 4b opposite, with one between the end faces 4a . 4b located gap 5 through a side wall 6a is bridged. Because the gap 5 behind the side wall 6a is this out 1 not directly visible.

The corresponding end faces 4a . 4b are rectilinearly inclined, with the first end face 4a and one of the bottom 2 opposite top 7 of the first barrier body A include an inclination angle c1 smaller than 90 ° between them. In contrast, also close the second front page 4b and the bottom 2 of the second barrier body B an inclination angle c2 between them, which is also smaller than 90 °. In the present case are the two end faces 4a . 4b aligned parallel to each other, so that the two inclination angle c1, c2 of the end faces 4a . 4b are identical. In this embodiment, the inclination angles c1, c2 are 15 °.

At the first barrier body A is an end bearing assembly 8th provided, which at the first end face 4a opposite end 9 of the first barrier body A is arranged. The first barrier body A is at its end 9 over a horizontal axis of rotation 10 at the bearing arrangement 8th pivoted. With reference to the representation of 1 is the first barrier body A of Leitschwellenschranke 1 in a closed position a1.

The second barrier body B is a stationary part of the barrier threshold 1 , Which not shown anchor or anchor baskets with fixed foundations 11a . 11b . 11c connected is. The foundations 11a . 11b . 11c lie in level of the bottom 2 at the same height as the ground 3 and are integrated into it. In contrast, the first barrier body A is unpaved on the ground 3 on, with its end bearing arrangement 8th about another foundation 11d is set on the traffic route, not shown. The foundation 11d the bearing arrangement 8th is below the ground 3 arranged, wherein this in the region of the bearing assembly 8th a recess 12 provides, within the bearing assembly 8th on the foundation 11d is arranged. The bearing arrangement 8th is also not shown here anchor or anchor baskets with the foundation 11d connected.

2 shows the threshold barrier 1 of the 1 in an open position a2. Here, the first barrier body A is about the horizontal axis of rotation 10 pivoted around. Thus, that protrudes the bearing assembly 8th opposite free end 13 of the first barrier body A with its first end face 4a detached from the second end face 4b of the second barrier body B in the height. By pivoting the first barrier body A about the horizontal axis of rotation 10 around it creates an opening 14 which, for example, the passage of a vehicle on the ground 3 through the threshold barrier 1 through it. When the open position is completely open, the barrier body A is pivoted vertically upwards and occupies an angle to the horizontal of up to 90 ° and possibly also over it.

As with respect to the bearing assembly 8th to recognize, this has a frame 15 on which the first barrier body A with the horizontal axis of rotation 10 combines. The frame 15 is designed as a rigid corner. The horizontal axis of rotation 10 is above the top 7 of the first barrier body A, being on a column 16 the bearing arrangement 8th rests. The pillar 16 is perpendicular to one to the ground 3 parallel floor plate 17 attached, over which the bearing assembly 8th with the foundation 11d connected is. In order to allow the pivoting of the first barrier body A is between the frame 15 and the bottom plate 17 a manipulator 18 arranged in the form of a cylinder, which by length and shortening its dimensions the frame 15 and thus the first barrier body A about the horizontal axis of rotation 10 pivoted around.

In the presentation of 2 is also apparent that the side cheek 6a on the first barrier body A in the region of its first end face 4a is fixed. Basically, the structure of the first and second barrier body A, B provides that the underside thereof 2 parallel to the top 7 runs.

3 shows a detail of the two free ends 13 the barrier body A, B in a slight open position a2. The schematic representation illustrated by a transparency of the side wall 6a the arrangement of a claw 18a on the first barrier body A. The claw 18a extends parallel to the top 7 over the first front side 4a of the first barrier body A away. In contrast, the second barrier body B has one in its upper side 7 arranged opening 18b on. The opening 18b is intended for the claw 18a in closed position a1 of the threshold barrier 1 at least in some areas. Thus, the claw attacks 18a of the first barrier body A in a manner not shown here in the closed position a1 at least partially into the opening 18b of the second barrier body B.

4 shows an alternative embodiment in the form of a Leitschwellenschranke 1a , which are on the threshold barrier 1 of the 1 and 2 based. In the present case, the threshold barrier 1a additional guide rails 19 on top of that 7 of the first and second barrier body A, B are arranged. This leads the Leitholme 19 initially to an increase in the entire threshold barrier 1a , which by the arrangement of the Leitholme 19 according to the requirements, the height can be adjusted. Thus, if necessary, two or more Leitholme 19 be arranged one above the other on the barrier bodies A, B. The coupling of the guide rails 19 via tension rods 20 passing through the guide rails 19 are directed into the barrier body A, B in. Good to see is that in the area of the gap 5 opposite end faces 21a . 21b the guide rails 19 to the inclination angle c1, c2 of the end faces 4a . 4b the barrier body A, B are adapted. The increase by the Leitholme 19 following, is also the cover of the gap 5 over a correspondingly extended side cheek 6b customized.

In this embodiment, the Leitholme 19 to be regarded as components of the barrier body A, B. In a reference to the barrier body A, B, these can consequently the Leitholme 19 include.

In order to create as smooth as possible and serving the leadership of any impacting vehicle transitions, has the Leitschwellenschranke 1a between the bearing assembly 8th and the first barrier body A pivotally mounted thereon, a shape-adapted transition cover 22 on. Accordingly, the bearing assembly 8th through a similarly shaped cover 23 hooded. In this view are also those bearing arrangements 8th with the foundation 11d coupling connecting means shown, which in the form of anchors 24 within the foundation 11d are arranged and via corresponding openings in the bottom plate 17 the bearing arrangement 8th with the foundation 11d tense. Analogous to the successively arranged on the barrier bodies A, B Leitholmen 19 are also the barrier body A, B in this case formed of successively arranged and interconnected in a manner not shown standard elements.

Opposite the in 4 illustrated closed position a1 the Leitschwellenschranke 1a shows 5 their open position a2.

6 shows the threshold barrier 1a of the 4 and 5 in a supervision. Basically, this supervision corresponds to omitting the Leitholme 19 the supervision of the threshold barrier 1 of the 1 , In this plan view it can be seen that in the region of the gap between the first and the second barrier body A, B on both sides side cheeks 6b are arranged. Thus, the gap becomes 5 on both sides by the side cheeks 6b bridged. In addition to the transverse to the longitudinal direction of the barrier body A, B extending foundations 11a . 11b . 11c In the present case, the dimensions of the below the bearing assembly 8th located foundation 11d seen. Furthermore, compared to the dimensions of the barrier body A, B broader designed cover 23 to recognize which by the transitional cover 22 is adapted to the dimensions of the first barrier body A. Furthermore, the supervision can be seen that the barrier body A, B on its underside 2 one opposite the dimensions of the guide rails 19 have greater width.

Also the present threshold barrier 1a has a connection between its barrier bodies A, B in the form of the claw 18a and the corresponding opening 18b on. In a schematic representation, it is made clear that said arrangement of the claw 18a and the opening 18b both in the barrier bodies A, B itself as well as in the Leitholmen arranged on these 19 can be done.

7 shows a cross section through the barrier body A, B of 1 and 2 , The barrier body A, B are facing from the bottom 2 to the top 7 extending thighs 25a . 25b on which at the top 7 through a footbridge 26 are connected. From the top 7 to the bottom 2 have the thighs 25a . 25b one to the bottom 2 towards widening course, with the legs 25a . 25b on the bottom 2 outward bends 26a . 26b include. Through the turns 26a . 26b , which are essentially parallel to the ground 3 extend, a corresponding width and thus a large footprint is possible, which allows a stable state of the barrier body A, B.

The barrier body A, B have at least one inner connecting plate 27 on which the thighs 25a . 25b in the upper third of the barrier body A, B connects to each other. Continue to be on the bottom 2 the barrier body A, B friction-increasing feet 28 arranged, which a possible displacement of the barrier body A, B on the ground 3 with corresponding resistance.

8th shows the threshold barrier 1a of the 4 and 5 also in a cut representation. Based on the already in 7 illustrated barrier bodies A, B has these on the top 7 additionally arranged guide rails 19 on. The Leitholm 19 is over the tie rod 20 connected to the barrier body A, B. This is due to the connection plate 27 of the barrier body A, B an abutment 29 provided within which the tension rod 20 is arranged. In this case, the tension rod 20 end not shown in detail external thread, which with a within the abutment 29 arranged and also not shown internal thread is engaged. Preferably, the thread is a coarse thread, as fast as possible bracing and loosening of the guide rails 19 to allow on the barrier bodies A, B.

The abutment 29 opposite end region of the tension rod 20 has a rod end, which can be detected via a corresponding handle. This may be, for example, a hexagonal head, which can be coupled with a commercial tool, not shown here, for example, a jaw or ring wrench, as well as a Aufstecknuss. The rotary movement which can be introduced into the tension rod via the tool becomes the guide bar 19 with the barrier body A, B braced or released from this.

For the simplest and safest possible connection between the guide rail 19 and to allow the barrier body A, B, is the web 26 of the barrier body A, B with a corresponding exhibition 26a provided, which extends in the longitudinal direction of the barrier body A, B and feet 30a . 30b of the Leitholm 19 is graspable. As a result, a non-slip state of Leitholm 19 on the barrier body A, B parallel to the ground 3 allows.

9 shows a perspective view of the Leitschwellenschranke 1a in the area of the gap 4 opposite end faces 4a . 4b the barrier body A, B. To clarify the Structure is the barrier body A, B otherwise covering side area, more closely their legs 25a . 25b , shown transparently. Furthermore, the transition between the Leitholmen 19 and the barrier bodies A, B, closer to the top 7 , mostly transparent. In this view, it is clear that the barrier body A, B initially at the end about extending perpendicular to the longitudinal direction of the barrier body A, B front sides 31a . 31b are closed. Between the front sides 4a . 4b the barrier body A, B extend perforated connecting plates 32a . 32b which are the front sides 31a . 31b with the front sides 4a . 4b connect and thus together form a four-sided closed box profile.

In contrast, they also show at the gap 5 opposite guide rails 19 end fittings 33a . 33b on which are formed like a frame. Between the opposing fittings 33a . 33b the guide rails 19 are the likewise inclined end faces 21a . 21b the guide rails 19 arranged.

As can be seen, the claw is present 18a in the area of the Leitholm 19 of the first barrier body A arranged. The same applies to those with the claw 18a corresponding opening 18b , which also in the Leitholm 19 of the second barrier body B is arranged. This illustrative representation can of course also on the arrangement of the claw 18a and the opening 18b directly in the barrier bodies A, B when omitting the Leitholme 19 be transmitted.

The claw 18a is formed of a flat iron, which extends in the longitudinal direction of the Leitschwellenschranke 1a extending boom 18c as well as an opposite angled hook section 18d includes. The angled hook section 18d is so opposite to the boom 18c and the claw 18a bent, that this in the closed position shown here a1 in the opening 18b attacks.

Within the arranged on the first barrier body A Leitholm 19 is a sliding locking element 34 arranged, which at least partially by the present in the closed position a1 opposite end faces 21a . 21b is displaceable through. The locking element 34 is about one around the tie rod 20 around arranged connection frame 35 with an electromechanical drive 36 connected. Thus, the locking element 34 by means of the electromechanical drive 36 in the longitudinal direction of the Leitholm 19 displaced.

If the barrier body A, B with arranged on these Leitholmen 19 are equipped, said Leitholme 19 Components of the barrier body A, B in the context of the invention. In this context, also the front page 21b a Leitholm 19 as part of the front side 4b of the second barrier body B, so that the front side 21a a Leitholm part of the front page 4a of the first barrier body A in the context of the invention. In this way, for example, the sliding locking element 34 both in one of the barrier body A, B and, if present, in one of the guide rails 19 be arranged so that this in the context of the invention in principle at least partially through the end faces 4a . 4b is relocatable.

Still goes out 9 show that the feet 28 over a crossbar 37 are connected to the first barrier body A. In contrast, the second barrier body B, although a crossbar 37 on, but this is not with feet 28 connected, since the second barrier body B is fixed anyway and thereby set on the foundations, not shown here.

10 shows the already in 9 illustrated connection of the threshold barrier 1a in the area of itself with their faces 4a . 4b opposite barrier bodies A, B as a detail in a side view. It is clear that the barrier body A, B additional coupling means engageable with each other 38 exhibit. The coupling agents 38 are in the area of the bottom 2 on the front sides 4a . 4b executed. One of the coupling agents 38 includes one at the first end face 4a arranged flap 39 , in contrast, the other coupling agent 38 one at the second end face 4b arranged pocket 40 having. The tab 39 is opposite the top 7 of the first and second barrier body A, B aligned at right angles. In the closed position a1 shown here are the tab 39 and the pocket 40 engaged with each other.

As you can see, the claw points 18a an opening 18e in her angled hook section 18d on. This embodiment is necessary if claw 18a and the locking element 34 are arranged at least partially in a touching position to each other. The opening 18e of the hook section 18d here serves to receive the locking element 34 in its advanced position. In this way, an additional safeguard between the two barrier bodies A, B is ensured by the first barrier body A by the locking element 34 both with the second end face 4b and / or the front side 21b and the angled hook portion 18d is bolted.

11 clarifies the structure of the coupling agent 38 in the form of a section of the 10 , The pocket 40 is through a bumper 41 formed, which over a footbridge 42 with the second end face 4b connected is. While the walkway 42 parallel to the ground 3 , closer to the bottom 2 the barrier body A, B, runs, is the bumper 41 opposite the top 7 as well as the bottom 2 aligned at right angles. Basically, the tab can 39 and the bumper 41 also in a range of 0.1 to 5 ° from the top 7 the barrier body A, B inclined to facilitate engagement with each other. As shown, the tab forms 39 in the present case an integral part of the first end face 4a ,

Already off 10 goes the arrangement of a coupling plate 42a out. The coupling plate 42a is arranged on the second barrier body B, closer in the region of its underside 2 , Here is the coupling plate 42a on the second front side 4b where it at least partially engages under the first barrier body A in the closed position a1.

With a view to 11 it can be seen that the coupling plate 42a in the form of an extension of the footbridge 42 in the area of the pocket 40 can be arranged. In the present case, it is a bent part from which the second end face 4b and the walkway 42 as well as the bumper 41 are formed. In the present embodiment, the coupling plate 42a cohesively with the insert pocket 40 connected. In a manner not shown, the coupling plate 42a Of course, with other areas of the pocket 40 be connected. So can the pocket 40 for example, at least partially on the coupling plate 42a rest.

Out 12 goes an alternative embodiment of the coupling plate 42a which in this case integrally integral part of the bottom web 42 is. In other words, in the present case, the second end face 4b and the coupling plate 42a made of a common bent part, whereas the bottom bar 42 through a region of the coupling plate 42a is formed. The walkway 42 This is due to the bumper 41 limited, which in the present case perpendicular to the coupling plate 42a is arranged. When connecting the bumper 41 and the coupling plate 42a it is preferably a cohesive connection.

Out 13 goes another detail of the 10 showing which the free end of the coupling plate 42a shows. In this view it becomes clear that the coupling plate 42a at least one receiving opening 42b includes. In contrast, the illustrated in slightly raised position first barrier body A at its bottom 2 at least one foot 42c on. The receiving opening 42b and the foot 42c are designed so that they correspond with each other. This is the foot 42c and the receiving opening 42b in closed position a1 of the threshold barrier 1 . 1a at least partially engageable with each other. The present is the foot 42c over a footbridge 42d connected to the first barrier body A. Here, the bridge extends 42d in a manner not shown transversely to the longitudinal direction of the Leitschwellenschranke 1 . 1a ,

14 shows a view of the second barrier body B looking at the second end face 4b , As you can see, this is the front side 4b upstream impact plate 41 to the course of the thighs 25a . 25b as well as the turns 26a . 26b adapted in shape. Furthermore, further coupling agents 38 visible, which in the form of recesses 43 in the footbridge 42 are arranged. Further, the bumper is 41 over two indicated vertical webs 44 from the second end face 4b spaced. In other words, the in 11 illustrated vertical webs 44 between the bumper 41 and the second end face 4b , where the recognisability of the recesses 43 and the vertical webs 44 in this case are due to the fact that the bumper 41 is shown transparent for clarity.

15 shows a plan view of the second barrier body B. In this view again the vertical webs 44 clearly over which the bumper 41 to the second end face 4b is spaced. Furthermore, the coupling plate 42a to recognize as underside extension of the second barrier body B. This view gives another view of the in the coupling plate 42a arranged receiving openings 42b free, two of which are present in the present case. As can be seen, the receiving openings 42b rectangular shaped, with the receiving openings 42b are rounded in their corners.

16 shows a view of the first end face 4a of the first barrier body A. It is clear that the tab 39 by two spaced apart and parallel slots 45 from the first front side 4a is made out. Furthermore, the first end face 4b in the area of the bends 26a . 26b arranged, peg-like projections 46 on which to the bottom 2 extend the first barrier body A out. The projections 46 correspond with those in the 14 and 15 illustrated recesses 43 , wherein the projections 46 and the recesses 43 are provided in the closed position a1 of the threshold barrier 1 . 1a at least partially engage with each other.

17 shows the already in 16 illustrated first end face 4b in a perspective representation. Good to see is that the first front page 4a opposite the turns 26a . 26b and the tab 39 is bent. In closed position a1 of the threshold barrier 1 . 1a arrive in the 11 illustrated vertical webs 11 with the slots 45 the first front side 4a engaged to increase the coupling between the barrier bodies A, B.

18 already shows in the 1 and 2 illustrated bearing assembly 8th in a section in perspective representation. To further clarify the structure of the bearing assembly 8th is it from the 4 and 5 resulting coverage 23 removed, whereas still the removable transition cover 22 is apparent. The barrier body A extends to a pivot bearing side adapter unit 50 , The bottom plate 17 has a limiter 47 on, which in the form of a flag plate on the bottom plate 17 is arranged and from there beyond its edge in the direction of the transition cover 22 extends.

The limiter 47 serves to laterally support the pivotable barrier body A in the closed position a1. This is realized by the fact that the limiter 47 at least on one side of the frame 15 is arranged, which is connected to the first barrier body A. Preferably, the limiter 47 on both sides of the frame 15 on the bottom plate 17 in level of the bottom 2 the barrier body A, B arranged so that a lateral support takes place on both sides. The lateral support is therefore canceled at the moment in which the first barrier body A is pivoted out of its closed position a1 into the open position a2. This pivots on the column 16 fixed framework 15 around the horizontal axis of rotation 10 around and goes thereby from the lateral encirclement by the limiter 47 out.

Out 19 goes a variant of the threshold barrier 1 . 1a in the area of their bearing arrangement 8th out. For this purpose, the first barrier body A a cross plate 47a on, which in the interior of the first barrier body A between his thighs 25a . 25b is arranged. The cross plate 47a extends transversely to the longitudinal direction of the first barrier body A.

As can be seen, the cross plate points 47a to the bottom 2 the first barrier body A directed towards cutouts 47b on. The cutouts 47b start at one to the bottom 2 directed edge region of the transverse plate 47a and extend limited upwards. In the present case are two such cutouts 47b at a distance from each other in the cross plate 47a arranged.

In contrast, with the cutouts 47b corresponding limiters 47c at the bottom plate 17 the bearing arrangement 8th established. The limiters 47c are designed as flagstones, which on the bottom plate 17 stand up and extend into the first barrier body A inside. The limiters are preferred 47a cohesively with the bottom plate 17 connected, for example by welding. In the presentation of the 19 it becomes clear that the delimiter 47c and the cutouts 47b of the cross plate 47a engage each other, provided that the first barrier body A is in the closed position a1. Here are the limiters 47c in a manner not shown in the closed position a1 through the cutouts 47b at least partially seized laterally.

As can be seen, in the first barrier body A two transverse plates arranged in parallel one behind the other are provided 47a present, with the bottom plate 17 also two rows of limiters arranged one behind the other 47c has. Accordingly, there are four limiters in the present case 47c available, which in the closed position a1 the Leitschwellenschranke 1 . 1a at least partially with the cutouts 47b in the sheets 47a engage. As a result, any lateral loads acting on the first barrier body A become in the region of the bearing arrangement 8th both over the horizontal axis of rotation 10 in the area of the top as well as over the limiters 47c in combination with the cutouts 47b the cross sheets 47a in the area of the bottom 2 added. In this way, any possible corrosion of the first barrier body A about its longitudinal axis in the event of an impact is effectively prevented.

20 shows the side view of a vehicle restraint system according to the invention 48 , which releasably connected to each other Leitschwellen 49 and a threshold barrier 1a according to the 3 and 4 includes. The barrier body A, B correspond in their cross section according to the 6 and 7 analogous to 6 designed cross-section of the barriers 49 , Furthermore, the Leitschwellen also not shown coupling means 38 to ensure a secure connection with each other and to the threshold barrier 1a to enable. Furthermore, the vehicle restraint system 48 also on the thresholds 49 arranged guide rails 19 which is also identical in cross section and thus analogous to the representation of 7 are executed. As can be seen, the threshold barrier according to the invention makes it possible 1a a seamless integration into a string of barriers 49 as well as Leitholmen 19 so that, for example, already existing systems easily through such a threshold barrier 1a can be supplemented.

In practice, therefore, the Leitschwellenschranke invention 1 . 1a into a string of barriers 49 and guide rails 19 to a vehicle restraint system 48 integrated. In the closed position a1 of the first barrier body A is the locking element by means of the electromechanical drive 36 through the opposite end faces 21a . 21b as an extension of the front sides 4a . 4b the barrier body A, B shifted through to fix them together. Depending on the design here is also the claw 18a by the displaceable locking element 34 also bolted by this through the opening 18e in the hook section 18d the claw 18a is guided. If necessary, now the sliding locking element 34 with the help of the electromechanical drive 36 withdrawn from this position, so that a pivoting of the first barrier body A is made possible. This is the manipulator 18 activated, which by its subsequent elongation the frame 15 opposite the bottom plate 17 lifts and the associated barrier body A together with any attached guide rails 19 around the horizontal axis of rotation 10 the bearing arrangement 8th pivoted around in the open position a2.

Especially in the closed position a1 of the barrier threshold 1 . 1a serve the coupling agents 38 in connection with the claw 18a and the delimiters 47 . 47c and the coupling plate 42a to allow a very stable connection between the opposing barrier bodies A, B. In addition to the case with the pocket 40 engaged tab 39 in particular, the pin-like projections 46 inside the recesses 43 while the hook section 18d the claw 18a in the corresponding opening 18b attacks. This results in an almost rigid connection between the end faces 4a . 4b which through the sidewalls 6a . 6b is supplemented. In addition to their leading feature are the side cheeks 6a . 6b in particular, a possible transverse load of the first barrier body A, for example, by an impact of a motor vehicle, over a larger area directly into the ground 3 initiated second barrier body B initiate.

Particularly advantageous in this case is the design of the barrier body A, B in combination with the need for attached Leitholmen 19 , since these can be constructed predominantly in the form of a modular system. Thus, the barrier body A, B from existing barriers 49 be constructed, which only in the region of the gap 5 need adjustment, such as in particular 8th evident.

Of course, the presently separate end faces 4a . 4b . 21a . 21b the barrier body A, B and Leitholme 19 be executed in one piece. Furthermore, also the locking element 34 as well as the so on the connection frame 35 coupled electromechanical drive 36 be arranged in or on one of the barrier body A, B.

In the context of the invention it is provided that the second barrier body B of the Leitschwellenschranke 1 . 1b also can be swiveled. Accordingly, the second barrier body B also on a bearing assembly 8th be arranged pivotally, resulting in spite of each short dimensions of the two barrier body A, B a wide opening in width 14 can be realized.

21 shows such an alternative embodiment of a double-leafed threshold barrier 1b another vehicle restraint system 48a , As already out 20 also known in the 21 shown vehicle restraint system 48a the first barrier body A and the second barrier body B, which in each case at their the gap 5 opposite ends 9 via storage arrangements 8a are pivotally mounted. As can be seen, the alternative vehicle restraint system continues 48a also from thresholds 49 and the first barrier body A and the second barrier body B together, on each of which individual guide rails 19 arranged and via tie rods 20 associated with these.

As already in the 7 to 10 shown, the two barrier body A, B are in the presently closed state on their feet 28 on the ground 3 on. In contrast, the barriers adjoining the barrier bodies A, B are in their longitudinal direction 49 over bolts 24a detachable with the underground 3 connected. A placed on the first barrier body A Leitholm 19 points in the area of the gap 5 a maintenance flap 51 on which of the in the 9 and 10 illustrated electromechanical drive 36 can be reached if necessary. In the area of end bearing arrangements 8a the threshold barrier 1b are additional sidewalls 6c arranged, which analogous to the side cheeks 6a . 6b in the area of the gap 5 between the two barrier bodies A, B also for gap coverage between the barriers 49 and the first barrier body A and the second barrier body B serve.

22 shows the vehicle restraint system 48a of the 21 in a supervision. In this supervision it becomes clear that the thresholds 49 as well as the two barriers A, B lateral exhibitions 26a . 26b own, as in relation to the two barrier body A, B in the 7 and 8th such as 14 to 16 shown. Those, the thresholds 49 with the underground 3 connecting bolts 24a are on each side of the barriers 49 through their lateral exhibitions 26a . 26b passed.

23 shows the vehicle restraint system 48a of the 21 and 22 in a perspective view of its closed position a1. To clarify the structure of the end bearing arrangements 8a the two barrier body A, B and their configuration in the region of the gap 5 are the two barrier body A, B and the Leitholme 19 partially transparent in the form of cutouts. This will provide a view into the interior of the vehicle restraint system 48a free. Their respective contents are the subject of the following 24 and 25 ,

24 shows a section of the view of the representations of the 23 left bearing arrangement 8a in partial transparent representation. As already to the 1 and 2 such as 18 the Leitschwellenschranken invention 1 . 1a executed, also has the bearing arrangement shown here 8a the alternative threshold barrier 1b a horizontal axis of rotation 10 around which the second barrier body B is vertically pivotable. The construction shown here applies accordingly also for the bearing assembly 8a of in 23 As can be seen, one is also the horizontal axis of rotation 10 storing column 16 exist, whereas the second barrier body B with a rotating element 52 connected is. Said rotary element 52 is from the horizontal axis of rotation 10 interspersed, which at the column 16 is supported. The connection between the rotary element 52 and the second barrier body B is designed so that a rotation of the rotary member 52 around the horizontal axis of rotation 10 around the vertical pivoting of the second barrier body B about the horizontal axis of rotation 10 causes around. In other words, the rotary element 52 and the second barrier body B connected rigidly to each other for this purpose.

As with the threshold 49 of the 24 recognizable, this also has at least one maintenance cover 51a which, if necessary, can be opened, for example, via releasable connection means. Behind this service cover 51a can a connection, not shown here, between the rotary member 52 and a suitable drive, the articulated connection by opening the maintenance cover 51a is accessible for any maintenance or service work in this way.

Out 25 goes a section of the connection of the closed threshold barrier 1b in the area of itself with their faces 4a . 4b opposite barrier body A, B forth. Due to the partially transparent presentation of the view is released into the interior, in this regard to the previous comments made in relation to 10 is referenced.

In addition, one is on the side cheek 6a adapted side plate 53 recognizable, which in the present case is arranged on the second barrier body B.

The side plate 53 is flat on the side legs 25b of the second barrier body B arranged. The side plate is preferred 53 at least partially cohesively with the side legs 25b connected, for example via a weld. That in its strength perpendicular to the surface of the side leg 25b to the side wall 6a adjusted side plate 53 is intended for the side cheek 6a to protect against any bending in the event of an impact. For this are both the side wall 6a as well as the side plate 53 with their outer surfaces parallel to the thigh 25b at least approximately at the same height. In this way, a possible penetration of areas with the vehicle restraint system becomes effective 48a colliding vehicle, in particular when hitting at a shallow angle on the Leitschwellenschranke 1b incident.

The 26 and 27 show that in 23 closed vehicle restraint system 48a with open barriers 1b , In the present open position a2, the first barrier body A was first pivoted, followed by the second barrier body B. To return to the in 23 shown closed position a1, this process takes place in reverse order, wherein first the second barrier body B followed by the first barrier body A on the ground 3 be swiveled back. This order is due to the arrangement of the side cheeks 6a . 6b necessary, which in the closed position a1 the second barrier body B in the region of its end face 4b and in the present case also in the area of the front side 21b of the arranged on the second barrier body B Leitholm 19 at least in certain areas.

In addition, this order is necessary to first the deposition of the first barrier body A partially in the closed position a1 under cross-coupling plate 42a of the second barrier body B on the ground B to allow.

With a view to 26 This allows you to take another look at the underside 2 of the second barrier body B, which already in the 9 and 10 illustrated trusses 37 with her at it arranged feet 28 shows. As you can see, the trusses extend 37 transverse to the longitudinal direction of the second barrier body B. Said trusses 37 with the feet arranged on it 28 are in a manner not shown also on the in 27 apparent first barrier body A at the bottom 2 available.

While the feet 28 a placing and lifting the two barrier body A, B from the ground 3 are possible, which are starting from the two bearing arrangements 8a from the threshold barrier 1b away extending barriers 49 over the bolts 24a firmly with the underground 3 connected.

Both in the 26 as well as in 27 is out again 19 outgoing floor plate 17 with the limiters arranged thereon 47c to recognize.

28 shows a view of the bearing assemblies 8a of the 26 and 27 , Because of both the first barrier body A in 27 as well as on the second barrier body B in 26 arranged identical storage arrangement 8a represents the in 28 illustrated bearing assembly 8a their respective structure again in partial transparent representation.

As already in 24 it can be seen here is the respective barrier body A, B with the rotary member 52 coupled. In this view it becomes clear that the rotary element 52 a boom in the form of a lever arm 54 which is different from the horizontal axis of rotation 10 extends. The lever arm 54 and the longitudinal direction of the respective barrier body A, B enclose an angle c3 between them, which is smaller than 90 °.

In the present case, the angle c3 is designed with an inclination of 45 °. At one of the horizontal axis of rotation 10 opposite end portion of the lever arm 54 this one has a point of attack 55 for a drive not shown here. When said drive is preferably a linear drive, which over the point of application 55 on the lever arm 54 is articulated, whereby by a limited rotation of the lever arm 54 around the horizontal axis of rotation 10 around the respective barrier body A, B also about the horizontal axis of rotation 10 is pivoted around. Said drive, not shown, is then preferred via the maintenance flaps 51a accessible.

The result is a modular and lightweight barrier barrier 1 . 1a . 1b as part of a vehicle restraint system 48 . 48a shown, which in particular in their connection area allows sufficient coupling to be used for high containment levels.
