DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a collar/display device for a fuel delivery device. In particular, the invention relates to a collar that can be fitted over at least a portion of a housing of a petrol discharge unit and/or a splashguard for the unit.
Most petrol pumps are provided with a concealed stationary pump for pumping petrol from an underground tank through a fuel pipe to a hand held and manually operable fuel delivery device. A typical fuel delivery device is shown in FIG. 1a. Such devices generally comprise the following main parts: a nozzle 1 through which fuel is delivered or discharged; a housing designated generally as 2 which houses a fuel metering valve, the housing having a knuckle portion 3 containing means for adjusting the valve; and a handle 4 which is held by the person dispensing the fuel. The handle usually has a trigger (or lever) 5 for adjusting the rate of fuel discharge and a finger guard. In addition a splashguard 6 may be provided on the nozzle to prevent fuel delivered by the device splashing back from the tank being filled. A commonly used fuel delivery device of the type shown in FIG. 1a is the ZVA (a Trade Mark) nozzle available from Elaflex Limited of the United Kingdom. Further well known devices include the OPW (a Trade Mark) nozzle from OPW Fueling Components Europe (BV) of the Netherlands, the Huskey (a Trade mark) nozzle available from Huskey Corporation of Tucson, Ariz., USA and the EMCO Wheaton (a Trade Mark) nozzle available from EW Fuel Management Limited of the United Kingdom.
Although the type of fuel is often displayed on or near the petrol pump itself, with the increasing variety of fuels available for motor vehicles there is a continuing need to ensure that a motorist wishing to refill with fuel does so using the correct type of fuel. Not only is petrol available in various grades such as four-star, but also as unleaded petrol (or lead-free) as well as special unleaded fuel that is intended to give improved performance (sometimes termed super-unleaded).
When one additionally considers diesel, this results in many different types of fuel being commonly available at petrol filling stations. It is imperative that the motorist fills the tank of his motor vehicle with the correct type of fuel (since most engines will only run on one type) and this is all the more reason why the correct fuel type needs to be clearly indicated.
In order to ensure that the correct type of fuel is chosen, the fuel delivery device is often labelled with the type of fuel it delivers in addition to the pump itself. Furthermore, the fuel line may be colour coded (for example, red for leaded petrol, green for unleaded and black for diesel). In addition the housing is usually covered by a flexible rubber shroud or "scuffguard" which usually covers the knuckle portion that contains the valve adjustment means.
The scuffguard is sometimes colour coded depending upon the type of fuel to be dispensed by the device (as described previously).
One known way of providing an additional indication of the type of fuel delivered by the delivery device is to replace the scuffguard altogether with a flexible cover having an internal configuration suitable to fit over the housing. The replacement scuffguard includes a generally planar upper portion onto which information material such as a suitably shaped piece of paper, plastic or cardboard having the information printed thereon is placed and retained by a clear cover having side walls which clip over the planar portion of the replacement sleeve, retaining projections on the side walls mating with corresponding recesses provided on the sleeve. Various problems are associated with the arrangement. In particular it is difficult to remove and replace the original scuffguard and by doing so, manufacturing or source information found on the original scuffguard is lost. In addition the cover can be easily removed and the information material lost either inadvertently or by acts of vandalism.
An improvement to the system comprises a collar which is configured t
