Description

The The invention relates to a vehicle restraint system according to Features in the preamble of claim 1.

Such a vehicle restraint system counts within the scope of WO 2008/040343 A1 to the state of the art. It has a Leitschwellenstrang from shot against each other set housing-like barriers, which are designed largely trapezoidal in vertical cross-section and provided with lateral Aufstandsschenkeln. The individual thresholds are closed on the upper side by means of cover plates and ends by means of end walls. Adjacent to the end walls, the cover plates are provided with recesses.

to Tension-and compression-resistant coupling of two consecutive barriers is an end wall of each threshold in the lower altitude range with an upstream, upwardly open pocket provided. The pocket is from the front wall and a distance formed to the end wall arranged boundary plate. In the pocket are located in the lateral distance to each other two vertically extending spacer bars. In the lower altitude range of other end wall are two of their lower edge outgoing, on provided the configuration of the spacer webs adapted receiving slots. When joining two thresholds is therefore the Pushed the end wall with the receiving slots into the insert pocket, wherein the spacer bars grasp in the receiving slots.

The Coupling in the upper altitude range of the barriers is caused by a tab, from the two webs in the same direction stick out. When mounting the tab, the webs take through the recesses in the cover plates behind the adjacent end walls the thresholds. By means of screws, the tab is then attached to the Cover plates attached.

Of the Invention is - starting from the prior art - the Task based, the known vehicle restraint system to make it more effective that at least the connection Easier to install in the upper height range of the barriers is and in the event of a vehicle impact, a higher Load can be suspended.

The Solution to this problem consists according to the invention in the Features of claim 1.

In the end walls of the Leitschwellen are now of the Upper edges of the end walls outgoing vertical slots provided. By means of a double-T-shaped coupling piece, with his bridge in the vertical slots of the end walls two consecutive thresholds sums up and with his Flanges behind the end walls of the two thresholds engages, these screwless tension and pressure resistant together get connected. The recesses adjacent the end walls in the cover plates allow easy handling each coupling, both during assembly as well as during the dismantling of a Leitschwellenstrangs.

According to the Characteristics of claim 2 are the vertical slots in the course of their the upper edges of the end walls adjacent sections formed divergent towards the upper edges. This facilitates that Inserting the webs of the coupling pieces in the Vertical slots and simplifies both the assembly and the Disassembly of the Leitschwellenstrangs. Nevertheless are from the bottom Sections of vertical slots high power transmissions guaranteed in the area of connections.

In Dependence on the place of use of a main barrier it may be advantageous according to the features of claim 3, that each threshold in a base housing and in one with the Base housing coupled attachment housing articulated is, in each case cover plates with end-side recesses and end walls have, wherein the vertical slots in the end walls the attachment housing and / or in the end walls the base housing are provided.

The Coupling of the attachment housing with the base housings can be achieved, for example, via vertically oriented tension rods, preferably quick-release or coarse threaded rods done. Here you can the top casings receive variable heights or it is also possible for two or optionally several attachment housings to be stacked on top of each other to be ordered. Vertical slots are only in the end walls the attachment housing, so the coupling of two to each other following base housing, for example by means of screw elements done, the holes in the end walls of the adjacent base housing push through. There are also other connection options Conventionally conceivable, such as screwless Connectors. The vertical slots can also only in the upper height ranges of the base housing be provided. In these cases, the attachment housing in any other form coupled together. It is conceivable It is also true that both in the end walls of the base housing as well as in the end walls of the attachment housing Vertical slots provided and couplings for connection both the base housing and the attachment housing be used.

If the base housing in the vertical cross section largely trapezoidal are designed according to claim 4 in adaptation to this form, that the attachment housing has a substantially rectangular, have downwardly open, box-shaped cross-section. The inclined side walls of the base housing go then almost without a jump over into the side walls of the attachment housing.

To Claim 5, it is advantageous that, starting from an end face the coupling pieces, in the longitudinal direction Seen, the webs shorter than the flanges formed are. The webs then have about the length of the vertical slots in the end walls. The protruding lengths the flanges then serve in conjunction with the end walls in addition, in a collision of a motor vehicle, a higher To ensure power transmission.

The Couplings can according to the characteristics of claim 6 may be formed of double-T profiles.

imaginable but it is also that according to claim 7, the coupling pieces made of T-profiles and welded to the webs of the T-profiles Flat iron are formed. This is appropriate, if appropriate, if no standardized double T-profiles are used to connect two barriers be available.

to Stiffening of the end walls of the attachment housing are according to claim 8, these end walls with transverse webs provided near the ends of the vertical slots on the insides the end walls extend.

Furthermore it may according to the features of claim 9 for Stiffening of the end walls of the attachment housing be beneficial to the end walls in the areas next to to provide the vertical slots with reinforcing plates.

Independently of whether a barrier formed integrally or from a Base housing and an attachment housing assembled is, it is inventively particularly advantageous Considered that an end wall of each threshold in the lower altitude range provided with an upstream, upwardly open pocket is, in which two in the lateral distance from each other, themselves vertically extending spacer webs are provided, wherein in the lower Height range of the other end wall two from its lower edge outgoing, adapted to the configuration of the spacer webs receiving slots are provided.

With 1 is in the 1 a consisting of sheet steel Leitschwellenstrang referred to as part of an otherwise unspecified illustrated vehicle restraint system. The Leitschwellenstrang 1 consists of several housing-like thresholds 2 together. In the embodiment, have the thresholds 2 a substantially trapezoidal cross-section with two lateral risers 3 , To the riot thighs 3 close in the surface closed inclined side walls 4 at. The two side walls 4 are upper side by a cover plate 5 connected with each other. End of the thresholds 2 are end walls 6 . 7 intended. Adjacent to the end walls 6 . 7 are in the cover sheets 5 recesses 8th intended. Inside are the thresholds 2 stiffened. Recognizable are horizontal cross plates 9 between the side walls 4 ,

An end wall 6 every threshold 2 (see also 2 ) is in the lower height range with an upstream, upwardly open pocket 10 Mistake. The pocket 10 is from the front wall 6 as well as a boundary plate 11 whose configuration is the configuration of the threshold 6 in the lower altitude range corresponds. In the pocket 10 are two spaced laterally spaced, vertically extending spacer bars 12 intended.

In the other end wall 7 every threshold 2 ( 1 ) are in the lower elevation two of their lower edge 13 outgoing, to the configuration of the spacer bars 12 adapted receiving slots 14 intended.

When installing a Leitschwellenstrangs 1 each new threshold to be set is 2 (please refer 1 ) lowered from above to the ground, that with the receiving slots 14 provided end wall 7 in the pocket 10 the already laid threshold 2 engages, with the spacer bars 12 in the pocket 10 in the receiving slots 14 slide.

This mounting situation is based on the end walls 6 . 7 two consecutive, not shown thresholds 2 from the 3 and 4 recognizable.

As the 1 to 4 can be seen further, are in both end walls 6 . 7 every threshold 2 from the top edges 15 the end walls 6 . 7 outgoing vertical slots 16 intended. The depth of the vertical slots 16 corresponds to about a quarter of the total height of a threshold 2 , As here in particular the 4 clearly shows are the vertical slots 16 in the course of their upper edges 15 the end walls 6 . 7 adjacent sections 17 to the top edges 15 formed divergent.

The vertical slots 16 serve to absorb from the 11 and 12 closer recognizable double T-shaped couplings 18 . 19 , This shows the 11 a coupling piece 18 , which consists of a double-T profile, while the coupling piece 19 of the 12 from a T-profile 20 and one to the jetty 21 of the T-profile 20 welded flat iron 22 consists. The 11 and 12 can also be seen that, starting from an end face 23 the couplings 18 . 19 , Seen in the longitudinal direction, the webs 24 . 21 shorter than the flanges 25 are formed.

After the coupling of two thresholds 2 over the pocket 10 on the front wall 6 and the receiving slots 16 in the front wall 7 is in accordance with the 1 . 3 or 4 a coupling piece 18 or 19 , here for example the coupling piece 18 , so from above with the two thresholds 2 connected to the footbridge 24 of the coupling piece 18 in the vertical slots 16 grips while the flanges 25 of the coupling piece 18 through the recesses 8th in the cover sheets 5 and behind the adjacent end walls 6 . 7 the two to be coupled barriers 2 to grab. The length of the bridge 24 . 21 a coupling piece 18 . 19 corresponds approximately to the height of a vertical slot 16 , The flanges 25 overlap the end walls 6 . 7 below the vertical slots 16 and serve here the stiffening in the dome area of two barriers 2 ,

In the 5 to 7 is a Leitschwellenstrang 1a from shot-wise juxtaposed cabinet-like barriers 2a shown, in which each threshold 2a in a base housing 26 and in one with the base housing 26 coupled attachment housing 27 is articulated. Each attachment housing 27 is with the associated base housing 26 firmly connected by means not shown, vertically aligned tie rods.

While the base case 26 in terms of their design essentially the thresholds 2 of the Leitschwellenstrangs 1 of the 1 to 4 match, let the 5 and 6 recognize that the cover sheets 28 the base housing 26 an upward bulge 29 own, such that in addition to the bulge 29 two support strips 30 for supporting the inwardly folded flanges 31 the a largely rectangular, downwardly open, box-shaped cross-section having attachment housing 27 be formed (see also 8th ). The end walls 32 the base housing 26 are coupled together in the upper height range by means not shown bolts, which holes 33 in the end walls 32 push through.

The end walls 34 the attachment housing 27 of the Leitschwellenstrangs 1a of the 5 to 7 wise, like the end walls 6 . 7 the thresholds 2 the embodiment of the 1 to 4 (see also 8th to 10 ), from the upper edges 35 outgoing vertical slots 16 on, in the course of their upper edges 35 adjacent sections 17 to the top edges 35 are designed to divergent. Furthermore, let the 9 and 10 realize that the end walls 34 the attachment housing 27 with crossbars 36 are provided, which are located near the ends of the vertical slots 16 on the insides of the end walls 34 extend. In addition, the end walls 34 the attachment housing 27 in the areas next to the vertical slots 16 with reinforcement plates 37 Mistake.

The coupling of two successive attachment housing 27 takes place as with the thresholds 2 of the 1 to 4 by means of coupling pieces 18 . 19 according to the 11 and 12 such that these couplings 18 . 19 with their webs 24 . 21 be lowered so that they are in the vertical slots 16 in the end walls 34 adjacent attachment housing 27 grasp the flanges 25 the couplings 18 . 19 behind the end walls 34 to grab. For perfect assembly and disassembly of the couplings 18 . 19 are in the cover sheets 38 the attachment housing 27 next to the end walls 34 recesses 8th intended.
