Definitions

  • the invention relates to devices intended to dissuasively slow down the speed of motor vehicles.
  • Such devices are arranged on the roadway to dissuade drivers, approaching a pedestrian or dangerous area, from approaching this area at high speed.
  • These devices are either constituted by an arrangement of the roadway, forming what is commonly called a speed bump or an elongated gendarme, or composed of means added and fixed to the roadway.
  • US Pat. No. 3,389,677 discloses a device composed of a downstream transverse tube swelling by the air expelled from longitudinal tubes when the vehicle passes over them.
  • Such a device which therefore uses elastic means capable of being deformed by a compressible fluid, in proportion to the speed of the vehicle, has the drawback of requiring long and expensive tubes to be effective.
  • using elastic tubes and a compressible fluid it has a long operating time and provides results that are all the more random as the inflation of the tube transverse depends on its leakage rate in an auxiliary tank.
  • the object of the present invention is to provide a retarder device which eliminates, for vehicles not exceeding the authorized speed, all the inconveniences consecutive to its crossing, but reacts quickly by forming a firm protrusion generating a dissuasive shock on the wheels of a vehicle. approaching it beyond the authorized speed, while quickly resuming its resting state after passing over the vehicle.
  • This device is of the type composed of several longitudinal tubular conduits which, parallel to each other and arranged on a roadway, parallel to the direction of movement of the vehicles, are closed at their upstream end and communicate by their downstream end with an inflatable and elastic transverse chamber. containing the same fluid as them.
  • each of the inflatable chambers is arranged in a deformable envelope, of inextensible material, forming a transverse projection having larger dimensions than the inflatable chamber when the latter is in the defrosted state, and , on the other hand, is filled at least at atmospheric pressure with an incompressible fluid, also filling the tubular conduits, while, on the one hand, these tubular conduits are made of a deformable, but inextensible material, and are provided with corridors to transfer the fluid out of the pressurization zone by one of the wheels of the vehicle, and of means controlling the differential flow created in the direction of the inflatable chamber, so as to increase this flow in proportion to the speed of the vehicle and , on the other hand, a flexible protective and rolling mat for vehicles covers all of the longitudinal tubular conduits and envelopes tr ansversales.
  • the support of its wheels on the upper belt and on the tubular conduits compresses some of these conduits causing the displacement of the incompressible fluid which they contain.
  • the fluid divides in the conduits requested in an exhaust or transfer flow, tending to be distributed outside the zone subjected to the pressure, and in a differential flow tending to swell. the inflatable chamber.
  • the relative proportions of the two flows depend on the means of control.
  • the differential flow When the vehicle is traveling on the device at a speed below the limitation threshold, the differential flow is low and insufficient to inflate the chamber, so that the vehicle can deform the deformable envelope containing the inflatable chamber without being subjected to a deterrent jolt. .
  • the differential flow when the speed of the vehicle exceeds the limitation threshold, the differential flow is the greatest and causes the inflation of the chamber inside the envelope, envelope which thus forms an obstacle having the structure of a tire. inflated by an air chamber and a hardness all the more important that the inflation pressure is high, and therefore that the vehicle drives fast.
  • the projection thus obtained therefore has a variable rigidity providing a deterrent adapted to the speed of the vehicle.
  • the means controlling the differential flow and acting on the transferred flow are constituted by valves cooperating with openings formed in the side walls of the conduits and constituting lateral transfer corridors.
  • these means consist of the upper wall of each tubular conduit forming a throttling member by cooperating with the base of the conduit, provided with at least one groove for transferring the fluid.
  • the device consists of a base 1 on which is fixed a membrane 2 covered by a flexible mat 3 serving as an interface between the vehicle tires and this membrane.
  • the base 1 made of deformable but inextensible material, and for example of reinforced rubber, comprises, as shown in Figures 2 and 6, several rows of cells 7-7a open upwards, delimited by ribs 6 forming a grid.
  • each of the openings 20 and 22 is intended to cooperate with a valve, respectively, flow limiter 4 and unidirectional 5.
  • each of the openings 20 and 22 is associated with a recess made in the bottom of the cell, referenced respectively 23 for the openings 20 and 24 for the side openings 22. It is obvious that these recesses do not cross the bottom of the base.
  • the bottom of the base may include, below each of the cells 7, recesses 25 which soften it locally.
  • the membrane 2 shown in more detail in FIG. 7, is constituted by a sheet of deformable but inextensible material having a small thickness.
  • This membrane is linked to the base 2 by bonding to the ribs 6 or, as shown in FIG. 3, by tabs 17 with studs 17a which snap into T-shaped grooves 10 made in the ribs 6.
  • FIG. 7 shows that these the tongues are arranged in the intervals between the flaps 9 and 13 constituting the valves 4 and 5.
  • the tongues, as well as the flaps 9 and 13, can come from molding with the membrane 2, but can also be attached by gluing to it this. Under these conditions, and as shown in Figure 7, each of them has a wide base 9a-13a improving its attachment to the membrane and stiffening its position relative to the latter.
  • the mat 3 which is linked, at least by its edges, to the edges of the base 1.
  • FIG 4 showing in more detail the structure of a flow restrictor valve 4, shows that the flexible flap 9, constituting the valve itself, is disposed in a side opening 22, plunges into a housing 8 formed at the bottom of the recess 24.
  • the lateral faces 11 and 12 of this housing 8 constitute abutment faces which limit the movements of the flap 9 and form a kind of seat.
  • the lower end of the tab 13 constituting the valve is at a distance from the bottom of the housing 26, to form with the latter a channel allowing the fluid to pass, and comprises in its zone of attachment to the membrane 2 , a reduction in thickness 13b giving it greater elasticity than the flaps 9 of the valves 4.
  • the passage section of the lateral valves 4 is greater than that of the unidirectional valve 5 associated with the same cell.
  • Each row of cells 7 forms with the intermediate membrane 2 a tubular conduit designated, rexpectively by A, B, C and D in FIG. 2.
  • Each conduit communicates by an opening 29 with the last cell 7a of each row not comprising, by elsewhere, no other opening in its walls.
  • Each cell 7a is closed in its upper part by the membrane 2 which comprises, in this location, a shaped part 2a constituting a projection, deformable but inextensible.
  • the projections 2a are aligned transversely to the direction of circulation of the roadway and are arranged in a tunnel 3a formed in the carpet 3.
  • the housing 31, formed by each cell 7a and part 2a of the membrane, contains an inflatable chamber 30, the conduit 32 is connected to the opening 29 communicating with the penultimate cell of the row.
  • the chamber 30 is made of elastically extensible material. It is filled, like the tubular conduit with which it communicates, by an incompressible fluid, such as water, under a pressure at least equal to atmospheric pressure. In its filled and deflated state, it occupies a volume whose dimensions are smaller than those of the dimensions of the internal housing 31 delimited by the cell 7a and the part 2a of the membrane.
  • an incompressible fluid such as water
  • the retarder device is arranged either directly on the roadway, or in a recess, formed therein, having a depth such that the upper face of the carpet 3 is at the level of said roadway. Furthermore, the device is oriented so that the conduits are parallel to the direction of circulation and that all the one-way valves 5 allow the fluid to pass in the direction of circulation of the vehicles, represented by the arrow 28 in FIGS. 2 and 5.
  • Such a device operates on the principle of a hydrostatic pump using the energy of the vehicle passing it. More precisely, when a vehicle enters the device, each of the tires on its wheels is supported, in width, on at least one longitudinal row of cells 7. The weight and energy of the vehicle are therefore instantly communicated, by the mat 3 and by the membrane 2, to the liquid contained in the cells 7 of the row. If the vehicle speed is lower than the regulated speed, the water expelled from a cell passes through the side valves 4 and the longitudinal valves 5, bypassing their flaps 9 and 13 from below and passing, without much pressure loss, through the corresponding recesses and housings. The water thus driven from a cell transits towards the lateral cells to return to the starting cell as soon as the tire has passed to the next cell of the same row.
  • the flow of water driven by each cell reaches the critical threshold in the side flow restrictor valves 4, that is to say causes the flaps 9 to tilt in the direction current until they contact the walls 11 or 12 of the housing 8, and causes the closure, at least partially, of this valve.
  • the transfer flow is thus reduced while the differential inflation flow is increased, increased, moreover, by the closing of the one-way valves 5 disposed upstream of the cell subjected to the pressure of the wheel. It follows that the water can leave the solicited cell only by borrowing the one-way valve 5, then open and disposed in front of it, to go in the direction of the last cell 7a and into the chamber 30.
  • This transfer is carried out, successively from cell to cell, as the vehicle advances on the cells and this until the last cell 7a of the row and the chamber 30.
  • the latter is subjected to an influx of water which causes it to swell in the housing 31.
  • the chamber follows the internal shape of this housing, and stiffens the part 2a of the membrane and locally the tunnel 3a. It causes the formation of a projection 33 all the more resistant and rigid as the pressure, therefore the speed of the vehicle is high.
  • valves 4 and 5 open and the inflated cells empty into the lateral cells by the valves 4, aided in this by the elasticity of the elastic chamber 30, then in extension.
  • the longitudinal openings 20 formed in the base 1 do not include one-way valves 4 in order to allow circulation in both directions on the device. This configuration resolves the possibility that a vehicle passes on the center line of the roadway to travel on the retarder device reserved for the other direction of traffic.
  • Each tubular conduit 35 is arranged parallel to its neighbors and to the direction of movement of the vehicles, between a base 36 and an upper belt 37. All of these elements are made of deformable, but inextensible, armed or unarmed materials.
  • Each duct 35 is composed of a bottom 38 and an arched and deformable upper wall 39.
  • the bottom 38 has longitudinally at least one, and in this case two grooves 40.
  • the downstream end of the duct is closed and its upstream end is provided with an opening 42 in which is engaged the end of a duct 43 of an inflatable chamber 44.
  • the duct 43 through a suitable opening through the wall of a tubular casing 45, of semi-circular section with flat bottom, made of a deformable and inextensible material.
  • This envelope is arranged transversely at the downstream end of the conduits 35, in alignment with the other envelopes, in a tunnel 37a formed at the downstream end of the belt 37.
  • Each conduit 35 and corresponding chamber 44 are filled with an incompressible fluid, such as water, at a pressure at least equal to atmospheric pressure.
  • an incompressible fluid such as water
  • the chamber occupies a volume less than that internal to the envelope 45.
  • a vehicle wheel 11 When a vehicle wheel 11 runs longitudinally on one of the conduits, it locally lowers the level of the mat 37 and that of the upper wall 39 of the conduit which then constitutes a throttling member, reducing the section of the conduit to a value equal to the sum of the sections of the transfer channels formed by the grooves 40.
  • the duct is therefore traversed by a transfer flow directed towards its upstream end and by a differential flow directed towards its downstream end, the value of which is all the greater that the vehicle has a high speed, that is to say that the throttling zone moves rapidly in the direction of arrow 28 and generates an instantaneous flow and a high pressure.
  • the chamber 44 inflates inside the envelope 45 and forms an obstacle all the more rigid as the speed is high. and constitutes a projection offering resistance to the passage of the wheels and generating a shock, like a blackcurrant.
  • the inflation threshold depends on the cross section of the grooves 40 in the bottom of the conduits 35
  • the value of this threshold is determined constructively by the cross section of the grooves and the deformation faculty of the upper wall 39 of the conduit.
  • the rigidity of the projection does not depend on a leakage rate affecting this projection, but on a differential flow of supply of the projection, the value of which depends on a leakage or transfer flow taking place upstream of this projection.
  • the pump members are made of deformable, but inextensible materials, and collaborate with an incompressible fluid, in order to exclusively use the pressure wave for inflation of the chamber, without inflation of the conduits, and obtain regular results. . Thanks to this, the return to normal of the device, after passage of the vehicle, is carried out very quickly without conservation of pressure in the inflatable chambers, which guarantees the reliability of the deterrence.
  • the communication channels between the tubular conduits and the respective inflatable chambers have sections which are determined so as not to constitute constrictions slowing down the inflation or deflation.
  • each of the conduits A or 35 has a flaring at most equal to half the width of a wheel tire and is separated transversely from its neighbors by a distance less than its own width so that each wheel rolls at least on a conduit.
