Definitions

  • the invention relates to a terminal with a connection end for its connection to a vehicle restraint system, with a linear guide that rises in a ramp-like manner in the longitudinal direction of the terminal towards the connection end and with a plurality of damper elements arranged in a row, which are movably mounted on the linear guide.
  • Terminals on a vehicle restraint system are known from the prior art.
  • the EP1381737B1 a terminal with a lowering and with damper elements.
  • the depression which rises in a ramp-like manner in the longitudinal direction of the terminal, is anchored to the ground via posts.
  • a linear guide is provided on the lowering, on which the damper elements arranged in a row are movably mounted to absorb impact energy.
  • the linear guide is formed by an undercut provided centrally on the depression and by T-shaped guide elements on the damper elements that engage in this undercut.
  • the invention has therefore set itself the task of structurally changing a terminal of the type described at the outset in such a way that it can stably absorb impact energy even at unfavorable impact angles.
  • the terminal should be characterized by its structural simplicity.
  • the invention solves the problem set by the features of claim 1.
  • damper elements have guide plates and the linear guide has guide recesses in the guide plates and at least two that run parallel to one another
  • the design of the guide elements that interact with the longitudinal profiles from guide recesses on guide plates of the damper elements can be produced comparatively easily and inexpensively - which significantly reduces the design effort on the terminal.
  • the terminal according to the invention can therefore fulfill the specified function with a high degree of security, even at a wide variety of impact angles - and is also characterized by structural simplicity.
  • damper elements can be further simplified if the guide plates form opposite end faces of the damper elements. These end faces of the damper elements are preferably flat.
  • a guide plate of the guide plates is provided between two adjoining damper elements, thereby forming the end faces of the damper elements, the construction of connected damper elements can be further simplified.
  • this structure of the damper elements can facilitate maintenance and/or repairs.
  • damper elements have longitudinal side surfaces made of sheet metal adjoining the end faces, damper elements that are structurally simple but still have a safe function can be created.
  • the degree of absorption of the damper elements can be adjusted particularly favorably if the long side surfaces are curved.
  • the longitudinal side surfaces each protrude from the end side surfaces adjoining them, viewed transversely to the longitudinal direction, in order to absorb a particularly large amount of energy from the impact in front of other parts of the damper element in question. These advantageously protrude outwards from the damper elements.
  • the damper elements can be structurally simplified even further if the longitudinal side surfaces are formed by half-shells, the half-shells having flanges at the opposite ends, each of which is firmly connected to an end face surface of the damper element in question.
  • the flanges are preferably screwed to the end faces via mechanical connecting means.
  • a comparatively high torsional rigidity on the damper elements can be achieved if the guide recesses are provided in the lower third of the guide plates. This is preferably done in order not to hinder the mobility of the damper elements on the longitudinal profiles even if the longitudinal side surfaces are deformed.
  • damper elements are hollow on the inside and/or the damper elements are open at the bottom and/or at the top.
  • the terminal preferably has at least two posts to which the longitudinal profiles, in particular their profile ends, are attached. This can, among other things, ensure a stable linear guide.
  • the posts are arranged between the longitudinal profiles.
  • the terminal can have a connecting element which, viewed in the longitudinal direction, is provided after the linear guide and is in particular attached to a post.
  • connection element preferably has a first longitudinal part and a second longitudinal part, which are connected to one another via second mechanical connecting means.
  • first and/or second longitudinal part has elongated holes running in the longitudinal direction, each of which is penetrated by one of the second connecting means, in order to allow a certain mobility of the terminal in its longitudinal direction in the event of an impact.
  • Spacer elements are preferably provided between the first longitudinal part and the second longitudinal part.
  • the connecting element can have a bend in its course in the longitudinal direction of the terminal in order to enable a certain lateral mobility in the event of an impact.
  • the terminal according to the invention can be particularly suitable for a vehicle restraint system.
  • the connecting element of the terminal is attached to a guide rail of the vehicle restraint system.
  • a vehicle restraint system 1 is shown with a guard rail system 2 shown, for example, and with a terminal 3 arranged at the beginning (or end, as not shown) of the guard rail system 2. But it is also conceivable that the terminal 3 is arranged on a concrete barrier, etc.
  • the terminal 3 is anchored to the ground 5 via two posts 4a, 4b, which are driven into the ground 5 for this purpose.
  • the posts 4a, 4b protrude from the ground 5 at different heights, namely at a lower height at the starting end 3a of the terminal 3 than at the connecting end 3b of the terminal 3.
  • the terminal 3 To absorb impact energy from a vehicle (not shown), the terminal 3 has a large number of internally hollow damper elements 6, which are arranged in a row one after the other - as in Fig. 2 to recognize.
  • damper elements 6 are movably mounted on a linear guide 7, which rises in a ramp-like manner in the longitudinal direction L of the terminal 3 in the direction of the guide rail system 2. This means that the linear guide 7 rises in a ramp shape at least in sections in the longitudinal direction L of the terminal 3 towards its connecting end 3b.
  • the linear guide 7 has two longitudinal profiles 8a, 8b which run parallel to one another and preferably at the same height and on which the damper elements 6 are slidably mounted.
  • the damper elements 6 have guide recesses 9a, 9b of the linear guide 7 that are complementary to the outer contour of the longitudinal profiles 8a, 8b, through which the longitudinal profiles 8a, 8b protrude - as in Fig. 3 to recognize.
  • the guide recesses 9a, 9b are provided in the guide plates 10 of the damper elements 6 and their dimensions are larger than the outer contour of the longitudinal profiles 8a, 8b, so that a play between the guide plate 10 and the relevant longitudinal profile 8a, 8b is achieved in sections.
  • the guidance of the damper elements 6 on the two longitudinal profiles 8a, 8b ensures that the damper elements 6 can be displaced.
  • the damper elements 6 can therefore absorb kinetic energy through deformation one after the other, even at different impact angles - which avoids an inadmissible increase in the deceleration forces during their absorption.
  • the longitudinal profiles 8a, 8b are formed by closed hollow profiles, preferably made of steel.
  • the guide plates 10 form the opposing flat end faces 11a, 11b of the damper elements 6.
  • only one guide plate 10 is always provided between two adjacent damper elements 6. This guide plate 10 therefore forms the end faces 11a and 11b for these two damper elements 6.
  • the damper elements 6 also have longitudinal side surfaces 12a, 12b made of sheet metal, namely sheet steel. These longitudinal side surfaces 12a, 12b are curved outwards in the longitudinal direction L and protrude from the relevant end side surfaces 11a, 11b transversely to the longitudinal direction L, i.e. in the transverse direction from the end side surfaces 11a, 11b. This means that contact with the front surfaces is less likely in the event of an impact - which increases safety.
  • the longitudinal side surfaces 12a, 12b are formed by half-shells 13, which have flanges 13a, 13b at the opposite ends.
  • the flanges 13a, 13b are angled inwards and are each firmly connected to an end face 11a, 11b, namely a guide plate 10, of the relevant damper element 6 - namely with first mechanical connecting means 19, namely screw connections, as in Fig. 4 to recognize.
  • damper elements 6 have two half-shells 13 arranged at a distance one above the other on each long side.
  • the frontmost or first damper element 6 on the terminal 3 only has a half-shell 13 on each long side of the damper element 6.
  • any number of half-shells 13 is conceivable - which has not been shown.
  • the guide recesses 9a, 9b are provided below the longitudinal side surfaces 12a, 12b. This ensures that even when the damper elements 6 are pushed together or deformed, the longitudinal side surfaces 12a, 12b do not become wedged with the longitudinal profiles 8a, 8b or their linear movement is not made more difficult as a result.
  • the guide plates 10 also extend in height normal to the longitudinal profiles 8a, 8b, which facilitates the displaceability of the damper elements 6 on the linear guide 7 in the event of an impact.
  • the profile ends of the longitudinal profiles 8a, 8b are each attached to a post 4a, 4b.
  • This attachment has a U-profile 21, which includes the relevant post 4a, 4b and engages in the relevant hollow profile of the longitudinal profiles 8a, 8b, as in Fig. 4 to recognize. This ensures the linear guide 7 a high level of stability.
  • the posts 4a, 4b are each designed as an I-profile.
  • the posts 4a, 4b are located between the longitudinal profiles 8a, 8b.
  • the terminal 3 is connected to the guardrail system 2 Fig. 1 and 2 shown in more detail.
  • the terminal 3 has a connection element 15, which is attached to the guide rail 16 of the guide rail system 2 on the one hand and to the ramp end of the linear guide 7, which represents the post 4b, on the other hand.
  • connection element 15 has a bend 17 along its course in the longitudinal direction L of the terminal 3. In the event of an impact, this ensures a lateral buckling or lateral mobility of the connecting element 15 in order to minimize the force input into the guard rail system 2.
  • the connecting element 15 has a first longitudinal part 15a and a second longitudinal part 15b, which are connected to one another via second connecting means 20, namely screw connections, which extend in the longitudinal direction L of the terminal 3 and pass through elongated holes 18.
  • the elongated holes 18 also allow a certain mobility of the terminal 3 in its longitudinal direction L - which further minimizes the force input into the guard rail system 2.
  • the connecting element 15 is therefore designed in such a way that before it buckles, the first and second longitudinal parts 15a, 15b are pushed together in order to relieve the other parts of the vehicle restraint system 1.
  • spacers for example washers, are provided between the first longitudinal part 15a and the second longitudinal part 15b in order to ensure this sequence.
