Definitions

  • This invention relates to a retractable road barrier comprising a barrier element pivotable about a first horizontal axis and an extensible and retractable drive mechanism, one end of which is pivotally anchored about a second axis, which is situated beneath and parallel to the first axis, while the other end is coupled to the barrier element.
  • Such a road barrier for instance to be used at the entrance of a parking lot to prevent unauthorized entrance, is known from GB-A-1 193901.
  • the extensible drive mechanism acts almost vertically beneath the barrier to push it upwardly when the barrier is to be erected.
  • the weight of the barrier acts directly upon the drive mechanism which must be dimensioned correspondingly or the barrier element must, as shown in said publication, be divided into a number of individually actuated sections.
  • the pit in which the mechanism is to be accommodated must be as deep as the distance over which the barrier element is erected and have a strong lower structure upon which the drive mechanism rests.
  • the invention aims to eliminate these drawbacks.
  • said other end is connected to an erecting element which cooperates with an erecting surface situated beneath the roadway and which rises towards the two said axes, and is also coupled, pivoting about a third axis parallel to the first and second axes, to the first end of a link of which the other end is coupled, pivoting about a fourth axis which is parallel to the other axes, to the barrier element at a point situated between the first pivot axis and the end of said barrier element.
  • the extensible drive mechanism When the road barrier is retracted the extensible drive mechanism is totally extended and lies parallel to the barrier element; the erecting element lies then at the lowest part of the erecting surface. To raise the barrier the drive mechanism is retracted so that the erecting element moves upwardly along the erecting surface and presses the barrier element upwardly by means of the link.
  • the few parts are all simple and can be manufactured cheaply; with a small depth and short strength the barrier element can rotate over a significant angle.
  • the simple and cheap structure makes it possible to use the road barrier for a great number of purposes, such as in self-service filling stations to prevent customers driving away without paying, protection of private and common parking places, protection of entrances, etc.
  • the drive mechanism is a ram actuated by a medium under pressure, preferably pressurized air.
  • the elongate erecting element is connected at its center to the piston rod of the ram and is at each of the two ends pivotably connected to a link.
  • the erecting surface merges at its highest point into a flat portion the barrier element is locked in its raised position and need not be kept in that position by permanent pressure medium in the ram.
  • the erecting element is coupled with at least one abutment engaging beneath the erecting surface extension of the driving mechanism will force the barrier element downwardly so that the retracting thereof is not dependent upon gravity and cannot be impaired by, e.g. dirt in its bearings.
  • a compensating spring is placed between the barrier element and the frame.
  • reference 1 denotes a road surface, e.g. the access to a car park.
  • the retractable road barrier is accommodated in a diagrammatically illustrated frame, the uprights of which are denoted by references 2, 3 and one longitudinal member of which is denoted by reference 4.
  • Said frame bears the barrier element 5 via a horizontal pivot 6.
  • the barrier element 5 bears a number of interconnected extensible closure elements 7, which screen the opening in the extended state (see Fig. 2).
  • a pneumatic cylinder 8 is disposed beneath the barrier element 5 in the frame and is pivotable about a second and likewise horizontal pivot 9 situated beneath the pivot 6.
  • the piston rod 10 is connected to the middle of an elongate cylindrical erector element 11 which can rise towards an erector surface 12 anchored in the frame.
  • the piston rod 10 passes through a central opening formed in the erector surface 12; of course two separate surfaces can be used.
  • the element 11 projects a short distance beyond the erection surface 12 and these ends are pivotally about a horizontal pivot 14 connected to the first end of a hook-shaped link 13.
  • each link 13 is coupled pivotably about a horizontal pivot 15 to the barrier element 5 at a point situated between the pivot 6 and the end 16 thereof.
  • Fig. 2 shows the end position of the barrier element, in which, in the embodiment illustrated, the erector element 11 comes to rest on the horizontal extension 12a of the erecting surface 12, so that the barrier element 5 is locked in this position and does not have to be kept in the end position by maintaining medium pressure in the cylinder 8.
  • an abutment 17 is coupled to the erecting element 11 and engages beneath the erecting surface 12 - as illustrated in the drawings - so that when the piston rod 10 extends and the erecting element 11 moves to the right the abutment 17 abuts the underside of the erecting surface 12 and the erecting element 11 with the links 13 coupled thereto, and hence the barrier element 5, automatically moves downwards.
  • a spring 18 may be provided between the barrier element 5 and the frame, but this is not essential.
