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 .
a road traffic speed control device which is locatable in a roadway, is formed of a resiliently deformable material and is deflatable by the passage of a vehicle thereover at the intended speed limit of said vehicle in said roadway, in use.
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 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.
Fig.l shows a schematic end sectional view of a road traffic speed control device and fixing therefor
Fig.2 shows a plan view of the device of Fig.l;
Figs 2A and 2B show sectional views along the lines A-A and B-B respectively of Fig, 2 ;
Fig.3 is a schematic sectional view of devices of Figs 1 and 2 located across a road;
Fig.4 is a schematic perspective view of a device showing drainage to discharge surface water
Fig.5 is a schematic end sectional view of an alternative device including a two-way valve for controlling deflation and reinflation, in use;
Fig.6 is a perspective view from above of a further alternative embodiment
Fig.7 is a schematic side sectional view of the embodiment of Fig 7.
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 idea 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
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.
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.
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.
