Definitions

  • the invention relates to a crash cushion for mounting on vehicles according to the preamble of patent claim 1.
  • Impact dampers serve to dampen the kinetic energy of a third vehicle colliding with a road maintenance vehicle, in particular to protect the occupants of the maintenance vehicles from injury. At the same time, the driver of the impacting vehicle, ie the person causing the accident, also benefits from a damped impact.
  • Impact absorbers are also arranged on road branches, in particular on Y-shaped branches on highways in the region of the projecting between the two branching lanes of guard rails. From the prior art, a crash cushion is known, comprising a box-shaped damping element, which on attached in a direction of impact elastically deformable strap.
  • the damping element from the use position ie lying on or slightly above the road, in a transport position which is perpendicular to the position of use, be pivoted.
  • the road maintenance vehicle can therefore, as soon as it is brought to a standstill for work, pivot the impact absorber and thus protect its occupants or possibly persons working in front of the maintenance vehicle from the consequences of a third party vehicle approaching the maintenance vehicle.
  • the production of this known impact absorber is very complex and therefore expensive, which means that not all road maintenance vehicles are equipped with such impact absorbers for cost reasons.
  • An object of the present invention is to provide an impact absorber for road maintenance vehicles and road signals, which is inexpensive to produce, has a low weight and can absorb a high degree of impact energy.
  • the cardboard, in particular corrugated, existing compartments can be assembled to form appropriately sized cubic bodies and form after welding or gluing in a tear-resistant film a very effective damper element. In particular, this has advantages if, after an impact, the protective container and possibly also the film burst, so that the filling, ie the compartments can emerge. Smaller or larger parts of the compartments that fly away can not hurt nearby people.
  • the compartment receiving foil which is preferably evacuated, additionally absorbs some of the kinetic energy, such as this does an air cushion.
  • the film protects the compartments, even if they are already treated against moisture, from destruction by the latter.
  • the impact absorbers are not made from a single compartment with a single film, but from several smaller packages, which in turn are arranged in turn, for example, in twos or threes within a protective container and / or foil sheaths. Depending on the required absorption energy, one, two or three such containers are arranged one behind the other and connected to one another.
  • a vehicle-mounted lifting / swiveling device allows the impact absorbers to pivot upward when not in use, ie while the vehicle is moving.
  • FIG. 1 illustrated maintenance vehicle 1, for example, a truck, carries at its end a wall 3, on the back of information signs or warning lights can be attached.
  • a composite of two damping elements 9 impact absorber 11 On the chassis of the maintenance vehicle 1 is mounted on a boom 5 on a pivot axis 7 a composite of two damping elements 9 impact absorber 11. The operating position is shown in solid lines, the transport position in broken lines.
  • the maintenance vehicle 1 is on a road 13, are on the third party vehicles 15 in the direction of arrow A on the way.
  • the damping elements 9 are formed as cubic blocks, which may for example have a height h of 0.5m, a depth t of 0.5m and a width b of 2m.
  • Each impact damper 11 includes, for example, two damping elements 9.
  • the damping elements 9 are housed in a cubic container 17 made of metal, preferably made of aluminum or plastic.
  • An aluminum container 17 is preferably made of strip-shaped aluminum, which is connected by a weld or a fold 19 at the bottom of the container 17.
  • the end faces are sealed by connected to the body parts metal plates 21.
  • the metal plates 21 may project beyond the abutting side surfaces in a flange. In the flanges holes 23 may be mounted so that two identical impact attenuators 11 together can be connected.
  • damper elements 9 are accommodated according to an advantageous embodiment. These fill the interior of the container 17 substantially completely.
  • the damper elements 9 consist of a compartment 25. This comprises a plurality of connected by plug connections to a body of cubic shape Gefachefrau 26, preferably corrugated board 27.
  • the corrugated board 27 have notches which extend over half the depth t and are at a distance x. In this way, stable cubes with rectangular cross-section through holes 29 can be formed without further connecting means or splice.
  • the through-holes 29 are covered by uncut corrugated board 31 at the top and bottom, and the entire body is welded, wrapped or glued in a film 33.
  • the film 33 is preferably a multilayer film 33, ie a laminate used which has a high tear resistance and also water vapor tightness.
  • a multilayer film 33 ie a laminate used which has a high tear resistance and also water vapor tightness.
  • a band-shaped wound around the compartment 25 in a crosswise or diagonally fashion.
  • Such wrapping films are used, for example, for the packaging of goods stacked loosely on pallets.
  • Air-tight wrapping films are also particularly used in agriculture, where green fodder is wrapped and held together as bales in such films.
  • the paperboard compartments 25 are impregnated to be resistant to moisture.
  • moisture-absorbing substances such as silica gel, may be inserted in the interior of the damping elements 9.
  • the damping elements 9 are inserted with lying through holes 29 in the container 17, in such a way that the longitudinal axis of the through holes in the direction of travel A of the vehicles 1 and 15 are aligned.
  • the force is applied via the metal plate 21, which forms the rear end face of the crash cushion 11.
  • the impact energy is then distributed and degraded by acting as air cushion, filled with the compartments 25, acting as a framework foil container.
