Definitions

  • This invention relates to a movable block for use in a lane separator.
  • Lane separators consisting of blocks positioned after another in a row is often used to separate vehicular traffic from oncoming traffic, pedestrians and road workers and for other applications where it is desirable to prevent a vehicle ending up in a place where it can do harm.
  • U.S. 6,413,009 Bl is an example of lane separators which is composed of blocks which are hinged at their ends. Such blocks may be made of reinforced concrete.
  • U.S. 6,413, 009 Bl describes blocks that are V-shaped towards the ends to prevent corner damage on impact, i.e. when the hinged elements turn relative to each other.
  • the blocks are further equipped with shock absorbers on the separator to reduce the shock on impact. Concrete blocks requires heavy load tool when deployed, and it is unclear to what degree a shock absorber, such as an elastic element or a deformable metal structure, absorb energy in the event of a collision.
  • U.S. 5,387,049 discloses a lane separator that have a row of containers filled with water or another shock-absorbing medium, and can be deployed and then filled with water. Longitudinal steel wires are stretched and secured in the blocks after deployment, so that the road blocks as a whole yield on impact and directs the car back into the correct lane. Disadvantages of this lane separator are that it requires tools and work to stretch the steel wire at installation, and long sections of steel wire must be replaced after a collision.
  • U.S. 6,913,415 Bl discloses a modular lane separator wherein each block has a first end with a protrusion that has a rotationally symmetrical end and a second end with a corresponding rotationally symmetrical recess.
  • a locking pin may be inserted in vertical bores through protrusions and recesses in two adjacent blocks so that the blocks are locked pivotally against one another.
  • the blocks may be made of rotational molded polyethylene, and is filled with for instance water.
  • the blocks can also be secured with straps, e.g.
  • Lane separator in U.S. 6,913, 415 has an inclined lower edge. If a car hits the edge, it will climb up onto the lane separator and possibly pass over the block.
  • the task to be solved by the present invention is to provide an improved block for the lane separator that solves at least one of the problems in the prior art.
  • the locking pin When the locking pin is formed of a hollow, deformable tube, a part of the vehicle's kinetic energy by such a collision is spent to deform the tube. Thus, there is less energy available to break loose protrusions with holes from the block, and the lane separator can therefore absorb more kinetic energy from the vehicle than previously known lane separators before the blocks are broken apart.
  • Each pair of neighboring blocks is preferably pivotally connected about their common locking pin.
  • a number of blocks are deployed at an angle between the longitudinal axes of adjacent blocks. If a vehicle with a velocity component in the length direction of the block hit the block, the block will move laterally and pull the neighboring blocks along with it.
  • the blocks will be connected as described above, to form a curve that directs the vehicle back to the correct lane.
  • the block is preferably hollow and has an inlet at the top and an outlet at the bottom. If the block is made of PE and filled with air, it will be sufficiently light so that it can be handled by one or two persons without lifting tools. When the block is in place, it can be filled with water, sand, gravel, concrete, antifreeze solution, foam or something else through the inlet. Thus, the block mass increase, so it does not move too much laterally on impact. Increased mass also causes the force of the block perpendicularly on to the ground, and thus the friction, to increase. During a collision a larger part of the vehicle's kinetic energy is consequently spent to overcome friction between the block and the substrate, so that there is less energy available for deformation of lane separator and vehicle.
  • the block also has at least one through-hole along the width axis.
  • the block side walls is held together by the walls of these holes, so that the block side walls do not bulge when the block is filled.
  • the block may further have baluster fastenings attached to the top portion.
  • Baluster fastenings may be sleeves or holes adapted to receive vertical fence posts.
  • baluster fastenings may be brackets with screw
  • attachments for vertical posts which, for example in turn, may be fastenings for safety fences, wire or other known means used to separate traffic.
  • the blocks can also be placed individually or in rows and form the foundation for noise barriers, road signs, billboards, bus shelters and more.
  • Lane separators may be equipped with a fence and/or a crash barrier at the top to prevent cars or car parts from passing the separator.
  • Figure 1 shows an embodiment of a lane separator seen in perspective.
  • Figure 2 shows a series of lane separator assembled into a row.
  • Figure 3 shows the embodiment of figure 1 seen from above.
  • Figure 4 shows the embodiment of figure 1 seen from the side.
  • Figure 5 shows the embodiment of Figure 1, viewed from one end.
  • Figures 6a-d show a preferred locking pin
  • Figure 1 is a perspective view of a preferred embodiment of a block 100
  • the block has a base portion 110 and a top portion 120 As shown in Figures 1 and 5, the base portion is wider than the top portion 120 when the block 100 is seen from one end.
  • the block 100 has longitudinally a first end 130 and a second end 140
  • the first end 130 having a recess 132 and protrusions 131, 133
  • the second end 140 having a protrusion 142 and recesses 141, 143
  • protrusion 142 fits into the recess 132 of the adjacent block, while the protrusions 131 and 133 of the adjacent block pass over and under the protrusion 142
  • the recesses and protrusions 131-133 and 141-143 is shown clearly in Figure 4
  • the block 100 is produced as a hollow body of a suitable plastic material, such as polyethylene (PE).
  • PE polyethylene
  • the block When the block is hollow, it can be emptied and removed without the use of tools and filled with, for instance sand or water before use.
  • the block may be produced by conventional methods, e.g., rotational molding and/or welding. Such methods are well known to those skilled in the art and are therefore not further described here.
  • Figure 2 shows a number of blocks 100 end to end so that protrusions and recesses are inserted into each other. Adjacent blocks are connected together by locking pins 150 inserted into bores 160 which substantially extends vertically, i.e. into the plane of the paper in figure 2
  • the base portion 110 side walls 111, 112 extends vertically. They lack in other words a ramp that can guide a vehicle up onto the block and in the worst case over the block where it can be dangerous for oncoming traffic or harm people.
  • the walls 111 and 112 should be sufficiently high so that wheel of a vehicle can not climb onto the block. If a vehicle drives into a lane separator of such blocks, the blocks thus shift laterally without the vehicle climbing upon the lane separator and passing over.

  • An inlet 170 is arranged at the top for filling of such a medium.
  • the figures also show an outlet 180 at the bottom of the block 100.
  • This outlet facilitates emptying of the block.
  • applications can be conceived in which the contents of the box should not be drained directly into the environment.
  • water containing glycol or other antifreeze may have been filled into the block to prevent the water freezing, expanding and damaging or destroying the block.
  • Glycol and other chemicals should not automatically be discharged directly into the environment through an outlet 180, but instead be pumped back through the inlet 170 for recycling or disposal.
  • the outlet 180 is not used in such applications, and can therefore be omitted in some embodiments.
  • the block 100 preferably has at least one through-hole 190 along the width axis, i.e. between the side walls.

Abstract

L'invention porte sur un bloc (100) pour un séparateur de files, lequel bloc a une première extrémité avec un creux (132) et des saillies (131, 133) et une seconde extrémité (140) avec une saillie (142) et des creux (141, 143) complémentaires, de telle sorte que les saillies et les creux (131-133 ; 141-143) s'adaptent dans les creux et les saillies des blocs voisins ayant la même forme que le bloc (100), et dans lequel les saillies et les creux comportent des perçages (160) adaptés à recevoir une broche de verrouillage cylindrique (150). La partie de base (110) a des parois latérales verticales (111, 112) qui empêchent un véhicule d'escalader le bloc. La broche de verrouillage (150) est constituée par un tube déformable creux, de telle sorte que l'énergie cinétique d'une collision d'une plus grande ampleur qu'autrefois déforme le bloc, et le véhicule à un moindre degré. Le bloc est creux et peut être déployé manuellement sans outils, puis rempli d'eau, de sable, ou similaire, au poids désiré. Le séparateur de files peut également être utilisé comme socle pour des signaux, et autres.
