Definitions

  • the invention relates to a shock absorber on traffic routes in series with each other arranged damping elements, the at least one common holding device be held and on at least one moving element, the a fastening arrangement for fixing to a damping element, slidably are arranged.
  • a generic crash cushion is known from DE 195 25 243.
  • Impact absorbers are two rows of damping elements arranged side by side in parallel.
  • the damping elements are connected substantially rigidly together and stand up Roll.
  • the common holding device is in this generic impact absorber formed by a rope construction, with a ground anchor in the head area of the impact damper is fixed. At the rear, the impact absorber points a support device on.
  • the tensioning cable is essentially starting from the ground anchor directed at a 45 ° angle upwards and is from about the 4th Damping continued horizontally.
  • the invention is based on the object, a crash cushion of the type mentioned to improve so that it, without changing its damper characteristic, a good Conductivity exhibits when hit by laterally approaching vehicles becomes.
  • the object is achieved in that the common holding device is located at a height above the ground that is less than the average clear height of the ground clearance of a car.
  • the fastening arrangement comprises a fastening plate in which the opening is designed to guide the common holding device.
  • the guide for the holding device is formed in the fastening arrangement is conventional damping elements can be used without any additional work should be performed on the damping elements.
  • the holding device is a continuous Rod is.
  • the holding device can be designed so that it is arranged below the damping elements.
  • the movement element is a sliding foot.
  • the holding device may have an upper rope. Then the damping elements may have openings for guiding the upper cable.
  • a ground anchor is provided at the head of the crash cushion which defines both the lower part and the upper part of the holding device are. At the rear end an abutment is formed, on which both the upper rope and the lower rope, possibly the lower rod are anchored.
  • the damping elements in the head region of the crash cushion, the damping elements a Height distance from the ground, which is equal to or slightly higher than that greatest height of the front ground anchor.
  • Fig. 1 shows a crash cushion 1 in a schematic representation in side view.
  • the Impact damper 1 is located in front of laterally adjacent to traffic routes as objects Protective device built on the one hand, the impact of a colliding on the object Vehicles dampen and thus damage from the occupants of the vehicle On the other hand, it also serves to protect the object.
  • the impact absorber is arranged in series one behind the other arranged damping elements 2, wherein a plurality of such rows in parallel may be provided side by side, but it may also be a V-shaped arrangement the damping elements are selected with different opening angles.
  • the Damping elements 2 are of at least one common holding device 3 so held that in the event of an impact, which is not exactly in the direction of the axis of symmetry done, do not dodge, or the entire construction is not at one oblique start of an accident vehicle overturned or the vehicle then get hooked.
  • the impact damper construction stands on at least one moving element 4, by means of a fastening arrangement 6 on a damping element. 2 is attached.
  • the moving element 4 allows the displacement of the damping elements during an impact in substantially any direction.
  • the common holding device 3 is at a predetermined height above the ground arranged.
  • the height 12 is less than the average in terms of their design clear height of the ground clearance of a car.
  • the moving element 4 has an opening 5 for the guidance of the holding device 3.
  • the guide is provided by a taut steel cable 3 ', which is fixed to a ground anchor 13 is.
  • the ground anchor 13 is arranged in the front region 14 of the crash cushion.
  • the other end of the steel cable 3 ' is at the end of the impact damper structure 1 at fixed an abutment 19, which at the same time as an impact block of the construction serves.
  • the cable 3 ' can by suitable clamping devices to a predetermined Size to be stretched.
  • an upper rope is 3 " provided, which also on the ground anchor 13 as well as on the abutment 19th is fixed.
  • the rope 3 " is first led obliquely upwards and is after the third or fourth damping element held horizontally by means of a deflection roller.
  • Fig. 2 is a view of the ground anchor 13 with attached ropes 3 'and 3 "shown. It can be seen that the two cables 3 ', 3 "on the ground anchor 13 next to each other are held.
  • the ground anchor 13 has, as can be seen from Fig. 3a, a base plate 15th on, in which fastening holes 18 are provided at suitable locations. At These mounting holes 18 bolts are performed in the foundation be screwed.
  • the ground anchor 13 has two bearing webs 16 ', 16 ", the at protrude beyond the edge of the base plate 15 in the illustrated embodiment. In the bearing webs 16 ', 16 "a common bearing bore 17 is formed, through which a bearing pin 22 (see FIG. 2) is inserted. To the Bearing pin 22, the ropes 3 ', 3 "fixed.
  • Fig. 4a - 4c shows an embodiment in front view, in plan view and in side view a movement element 4 according to the invention with a fastening arrangement 6.
  • the mounting assembly 6 has a mounting plate 6 ', which with a Opening 5 is provided for passing the common holding device 3.
  • the opening 5 is dimensioned so large that it is a taut steel rope or, as shown in this embodiment, a continuous rod 10 record can.
  • the damping element 2 is fixed.
  • mounting holes 20 are provided; However, it is also possible, the moving element 4 by means of a welding of the mounting plate 6 'to fix the damping element 2.
  • the movement element 4 is in the illustrated embodiment with a Gleitfuß 7 equipped.
  • the moving element also have a roller, a roller or a wheel.
  • Gleitfuß 7 also has at the lateral edges bends 8, which make it possible in a side impact, the arrangement of the damping elements side to move without getting caught on the ground and thus a tilting moment Experienced.
  • Fig. 5 shows a next embodiment, in which the holding and Movement device in a crash cushion construction with two side by side arranged rows of damping elements 2 is used.
  • the holding devices held on separate ground anchors 13 are.
  • the two Ropes 3 'and 3 "on the bearing pin 22 are arranged side by side, but then come to lie one above the other in a common vertical plane, wherein, as can be seen from Fig. 1, the lower steel cable 3 'or, optionally as a tubular steel 10, trained horizontally knowverumble, the upper steel cable 3 ", however At an angle of about 45 ° guided upwards and so folded on the guide roller 21 it will continue to run parallel to the ground.
  • the invention is not limited in its execution to the above preferred embodiments. Rather, a number of variants are conceivable which of the illustrated solution even with fundamentally different kind Designs makes use.
