The separating element has deformation element (2) provided between a stop (3) fixed on the road bump and thrust bearing (4) provided on the separating element, such that the deformation element is deformed by the force applied at the side of the separating element.

Description

1:1 The Invention concerns a traffic land boundary device for slowing down, guiding hack or stopping vehicles laterally deviating from the traffic 110¾ comprising divider elements which ire to be arranged along the edge of thi carriageway or between the traffic lanes thereof and which are arranged In a mw In the longitudinal direction and which are connected ÄogÄer hy way of connecting members at their end faces onented transversely mlitlve to the:: lonflfyÉnáf fcctidcy lie particular concrete and/or metal elements, preferably of the same configuration os each other. Traffic Mm lounlary divides of that kind are known: in many different forms in ptictfcc and; in particular in îSregions of reduced-width, carrlapways or slopes adjoining the carriageway - cannot leave their lane. When hitting such a traffic lane boundary device however a not inconsiderable amount of energy Is delivered by the vehicle to individual ones of the divider elements, sod they nave to absorb that by friction m relation to the ground or by deformation of the connecting 20 mem bem connecting them together or In same other fashion. In general that energy absorption emails positional displacement of the divider elements, and often there is not sufficient space available for mat ourpose, for example on bridges,

In addition a barrier wail for carriageways is known from WO tlDl/iiiSe, in which in -the same way inÉvifuel wall elements are respbiiveiy cmwäintf :tapth§r el. thalr ihdt aiiiaÄionaiiy connected to an enchdrage element in the ground by way rfea fixing member* The anchorage element is intended to prevent excessive displacement: of the wah elements In the Impact situation» in os der nonetheless to achieve a 30reduction in the Impact energy acting on the vehicle the fixing member is guided dlspiaceebly with respect to the anchorage element so that the wall element Is moveable into a position of being displaced by a predetermined distance.. That limited displaceabliity of the wail elements Is Intended to absorb a part of the kinetic energy of the vehicle, hut nonetheless to prevent excessive displacement of the well elements, W that Pile however the level of energy absorption depends on some parameters which are ilfffcuit to control, S A design configuration which Is an alternative thereto and which is also intended to permit deflection of crash harder aláments Is deseeded in DE 1.98 $5 44lx For the purpose the fixing device is plastically oeformable in the form of stretch elements. In this «a also goanfitatlvaly eptihllshing the level of energy absorption is possible only with difficulty. 10 In practice therefore those known devices still exhibit a detrimental" behaviour so that the problem of the invention is to improve a traffic lane boondafy device; pf the kind set forth in the opening part of this that with only slight spatial displacement of the divider elements: 3r* :m IfÄiÄi nonetheless i; considerably greater and 3smore accurately controllable amount of energy can be absorbed andfor converted,

According m the Invention that problem is solved in that provided bn the divider element Is at least one deformation member which Is in the form of a folding tube of meted and which is arranged between an abutment bömemher fixed to the carriageway and a thrust support provided on the divider element and is deformed with energy transformation when a force Ära Ily petl m Ä divider- element.

The advantage achieved by the Invention is substantially φ|£|(ΐτι& deformation member which is especially adapted for energy absorption is 2.5used for that purpose, which independently: of the properties of the divider element that are othirwlse required - ä :be so optimised as to convert a maximum amount of energy in accordance with the respective requirement». That can be effected for example In such a way that the energy is dissipated by plastic deformation or is also initially lohold in intermediate storage by elastic deformation.

In: a proliryed embodiment of the invention the deformation member In that case Is arranged in the base Tiglon of the divider element; In principle tor such a deformation member' to be arranged alternatively or additionally in an/ other region of the divider WmmÈk MMm Érpimuíarly appropriate for the deformation rpn^^: fpp«ist*d:' ;gg; ;|he divider element; lb the proximity of the centre of gravity thereof. Then the abutment member is also generally to fbi:mounted at a suitable height above the carriageway, in which case however for example !t is also possible to use for that purpose a crash barrier which is provided in any case at the carriageway edge, A configuration which has proven to he particularly advantageous and therefore preferred in accordance with the invention is one in which the lOdeformation member Is formed by a tube of preferably square or circular äcrqi|ysccfloh:v

There is in addition also the possibility of the metal tube being provided at one or both of Its ends with notches or indentations for promoting the folding action. Upon Initiation of the deformation that ! Senf or cas a preselected configurational change which Is desirably to be so selected that as a result a maximum of energy conversion is achieved.

In addition that affords the possibility of »electing the length of the metal tube in accordance with the energy to be absorbed.

Insofar however as an excessive displacement movement of the godäVider element has to be tolerated thereby there is likewise also the option of selecting the wall thickness and/or the diameter of the metal tube in accordance with the energy to be absorbed, in that case the material of the metal rwx can aiso be sekwee w aaord<wve with t,v *. 'vu gy to so absorbed, 25 There are also different possible options for mounting tne deformation member; thus In a first configuration of the Invention the thrust support for the deformation member can be arranged at the outside; surface of the divider element so that the deformation member Is outside the divider element. 30 In another embodiment of the invention in contrast the deformation member Is arranged in a guide receiving means of tne divider element, wherein the thrust support Is fixed within tne guide receiving means. In : 4 case therefore the déformation member is disposed within the divider element, there in a; gul^; pceivtng means,

That guide receiving means is desirably In the form of a recess, p fete re b i y a groove-shaped: fibess, in the bottom of the divider aliment, S To ensure a good holding action äh^:fÄ«gi::f§rÄ deformation member the abetment member h jgyiétsgfliify of ® shoe-ihap! configuration.

In addition it has proven to he advantageous if at its end towards thi thrust support the deformation member U provided with a ddnpecibd iöflange which Is screwed, riveted or connected in a similar manner to the thrust ayplstrt which It in the form of a connecting plate, lepodlipg on the respective configuration of the divider elemehf it r®W' tíislrtllf·Ifttl# iilit receiving means is provided1 will a metallic casing, iS Finally there Is also the option that the deformation member is provided with a guide bar which extends axially in Its interior and which can be connected with its one end to a crash barrier or the like and whose other idd is mountedpialiacdibly in the divider element,:

The Invention is described Id greater detail hereinafter by ^embodiments by way of example illustrated in the drawing In which:

The traffic lane boundary device shown In the drawing serves to slow down, guide back or stop vehicles deviating laterally from a carriageway. For that purpose the traffic lane boundary device comprises a plurality of divider elements ! which are arranged along the edge of the carriageway or xobetwdep the traffic f#pi§ihtreof oil arranged in a «? with each other In the longitudinal direction and which are connected together. Such divider elements I are preferably made from concrete or metal and are generally preferably of the same configuration is,each other.
