Definitions

  • the present speed hump can be either an asphalt or block paviour mound, which are formed directly upon the existing road surface or as an alternative can be made from a solid compound such as plastic which again can be fitted to the road surface.
  • EP-A-0,370,154 (generalu) describes a device for controlling the speed of vehicles on a roadway.
  • a series of longitudinal, tubular pipes parallel with one another and with the direction of the road traffic are placed on the roadway.
  • the pipes include inflatable chambers which are filled with a fluid that is incompressible at least at atmospheric pressure.
  • a differential flow is created in a direction of the inflatable chamber that causes an increase in the flow proportional to the speed of a vehicle and thus provides a deterrent hump in the pipes.
  • GB-A-2,288,419 (Beveridge) describes a deformable speed bump.
  • the speed bumps deform due to the displacement of a fluid within a flexible hollow casing, allowing vehicles to pass over them with the minimum of disturbance.
  • speed of a vehicle increases above the designed control.speed, the displacement of a fluid within the speed bump is progressively reduced so that the disturbance to vehicles increases as their speed rises.
  • the units are fluid-filled devices.
  • US 3,720,181 (Elkins) describes an elongated inflatable warning device adapted to be removably disposed transversely of a roadway during selected periods for control of vehicular traffic.
  • the device can be inflated through a non-return valve.
  • the device may be formed from an extruded or compressed partially recyclable rubber compound.
  • the device may be generally semi-cylindrical or sinusoidal in transverse cross-section and may be formed with perforations or apertures therein to permit deflation.
  • valve means may be located in a side wall of the device to allow deflation and reinflation, in use.
  • One or more helical springs which may be encased in a split sleeve, may be located within the device to assist in shape retention.
  • the device may be formed with perforations, apertures or valve means to provide deflation thereof with passage thereover of a vehicle travelling from a minimum speed of 8 km/h (5 mph) through increments to a required maximum.
  • the device may be formed such that subsequent to deflation by the front wheels of a vehicle passing thereover, reinflation may be delayed to allow the rear wheels to pass thereover during such initial deflation.
  • a road traffic speed control device D is preferably formed from an extruded or compressed recyclable rubber compound.
  • the shape represents a semi-cylindrical, sectional shape in construction with a series of apertures 3 formed through the profiled casing, which allows the circulation of air under controlled circumstances to be released, thus deflating the device D into a level plane giving a smooth passage to a vehicle passing thereover.
  • a helical spring 4 encased in a suitable split sleeve 5 is installed at the centre of the device D.
  • a spreader plate or washer 6 is inserted at the base of the protective shroud during the curing procedure to help relieve the impact force when in operation.
  • the device D is tapered into a fillet 7 at each end of the base line thereof.
  • the device D is preferably produced in 750 mm sections accompanied by tailor made inserts 8 to complete a road crossing (determined during the on site survey).
  • a 50mm spacer 9 is moulded onto the end of the unit which is interlocked at 10 to provide an overall 05mm expansion gap giving added rigidity to the whole structure.
  • the device D is attached to a road surface by bolts 2 engaging into anchoring devices 1 located in the road surface.
  • the ideal profile is 750mm in width and 100mm in height. This is uniform throughout the entire structure which enables vehicle manufacturers to work to a stated height restriction from the top of the hump to the underside of the vehicle similar to the restriction placed on high sided vehicles. Should damage occur, the section in question can be simply unbolted and replaced by a standard length of device causing minimal disruption and with no road excavation taking place
  • the number and size of apertures 3 is determined to allow the device D to be deflated by the front wheels of a vehicle passing thereover, providing the vehicle is not exceeding a predetermined speed.
  • the device does not deflate and acts substantially as a rigid hump.
  • Fig.3 shows a device D with drainage apertures 12 covered with mesh to prevent the ingress of leaves or other debris into device D.
  • Fig.5 shows an alternative device D having a two-way valve 13 provided to control deflation and reinflation and may be adjustable to control maximum speed at which deflation does not occur.
  • valve 13 may be provided in addition to apertures 3 or as on alternative thereto.
  • Figures 6 and 7 show a further alternative embodiment in which the cross section of the device is generally sinusoidal so as to provide a relatively smooth passage over a solid run up portion 14 of the device prior to a vehicle traversing the deflatable portion D.
  • the device provides a relatively smooth passage to vehicles travelling within a stipulated speed limit which is particularly important for emergency vehicles carrying injured passengers. Furthermore damaged portions of the device can be replaced easily without the requirement for excavation.

Claims (6)

  1. Dispositif de contrôle de la vitesse du trafic routier (D) qui peut être placée sur une route, ledit dispositif étant formé à partir d'un matériau déformable d'une manière élastique, ayant au moins une perforation, ou un ouverture (3), ou un moyen de vanne (13) qui y est disposé, pour permettre le dégonflement dudit dispositif, caractérisé en ce que l'air au sein dudit dispositif (D) est en communication avec l'atmosphère environnante et en ce que ledit dispositif (D) est dégonflable sous l'effet du passage d'un véhicule sur ledit dispositif à une vitesse limite prévue dudit véhicule dans ladite route, mais non pas à des vitesses dépassant ladite limite de vitesse, et est regonflable au moyen de sa souplesse après passage dudit véhicule.
  2. Dispositif (D) selon la revendication 1, caractérisé en ce qu'il est formé à partir d'un composé de caoutchouc partiellement recyclable extrudé ou compressé.
  3. Dispositif (D) selon la revendication 1 ou 2, caractérisé en ce qu'il a une section transversale semi-cylindrique ou généralement sinusoïdale.
  4. Dispositif (D) selon l'une quelconque des revendications précédentes, caractérisé en ce qu'un ou plusieurs ressorts en forme d'hélice (4) sont logés au sein du dispositif (D) pour faciliter la rétention de la forme.
  5. Dispositif (D) selon l'une quelconque des revendications précédentes, caractérisé en ce que le dispositif (D) est attaché à une surface de route par des boulons (2) s'engageant dans des dispositifs d'ancrage (1) situés sur la surface de route.
  6. Dispositif (D) selon l'une quelconque des revendications précédentes, caractérisé en ce que la résistance du dispositif (D) est ajustée de telle manière à ce qu'à la suite du dégonflement sous l'effet du passage par-dessus des roues avant d'un véhicule, le regonflement est retardé pour permettre aux roues arrières du véhicule de passer également par dessus, alors que le dispositif (D) est dégonflé.
