Description

Technical field

The present invention relates to nozzle boot arrangement comprising a nozzle boot for holding a nozzle and fuel dispensing unit comprising such a nozzle boot arrangement.

Technical background

A fuel dispensing unit, such as a petrol pump typically comprises a pump part standing on the ground, a display part positioned above the pump part and showing the chosen type of petrol, cash readout, volume readout etc., and a column to which one or more petrol hoses are connected.
When the tank of a vehicle is to be filled up, the driver parks the vehicle beside the petrol pump and opens the cover or cap of the petrol tank. The driver then selects the desired type of petrol, removes the pump nozzle from the nozzle boot and places the pump nozzle in the inlet of the vehicle's petrol tank and puts in the desired volume of petrol.
A difficulty that may arise in connection with filling-up is that the hose does not reach to the vehicle if parked a distance from the petrol pump. The reason why the vehicle has not been parked sufficiently close to the pump may be difficulty in manoeuvring owing to a limited space round the petrol pump. To allow the hose to reach the vehicle, it is usually necessary for the driver to park his vehicle so that the side of the vehicle where the filler cap is positioned faces the petrol pump. It is not always known to a driver of an unfamiliar vehicle whether the filler cap is positioned on the left or right side. This may result in the driver by mistake parking the vehicle on the wrong side of the pump and thus not being able to fill up the tank without moving the vehicle to the other side of the petrol pump since the hose does not reach all the way round the vehicle.
To be able to handle a hose of sufficient length it is important that the fuel dispensing unit is provided with a returning mechanism for the hose as well as proper guiding of said hose when it is pulled from a idle position within the fuel dispensing unit to an operating position outside of the fuel dispensing unit. Also, the construction of the fuel dispensing unit must be robust if several hoses along with the means for controlling them are to be incorporated in the fuel dispensing unit.
US4131218 discloses hose returning means for a fuel dispensing unit. According to the embodiment shown in Fig. 11 the hose is connected to a fuel supply connection arranged inside the housing and passes a floatingly suspended roller which is connected to a wire reel. When the hose is pulled, the roller is lowered in order to make more hose available for the user.
WO00/15542 discloses a hose storing device in which a flexible hose is passed over a roller which is accommodated in a housing in such manner as to be movable against a return force in substantially vertical direction.
A problem common for the hose returning mechanisms and their guiding means described above is their size, shape or extension within respective hose housings, which results in bulky and complicated structures. Also, the size of the devices directly reflect on the size of the entire fuel dispensing unit.
EP 0694499 discloses a fuel dispensing unit according to the preamble of claim 1.

Detailed description of preferred embodiments

Fig. 1 shows a fuel dispensing unit 1, having six hose storage spaces 2 and a column 3 extending vertically between and separating the electrical cabinet (not shown) and the hydraulic cabinet (not shown) from the hose storage spaces 2. Each hose storage space 2 is defined by a nozzle boot arrangement 4 and a opposing profile 5. The profiles 5 extends vertically from the bottom of the fuel dispensing unit 1 to the top. Accordingly, the profiles 5 constitute the structural construction of the fuel dispensing unit 1. Protection against insight can be placed between the profiles 5. The fuel dispensing unit 1 is connected to an underground fuel container (not shown). When filling up the tank of a vehicle, the fuel is pumped from the underground container by means of a pump (not shown) which is located in the hydraulic cabinet, and from there to the column 3 and out to a nozzle 6 via a fuel hose 7. When filling-up does not take place, the fuel hose 7 is accommodated in a hose storage place 2 and the nozzle 6 is inserted in a nozzle boot 8. The hose 7 is can be handled by a retracting mechanism (not shown), which is arranged in every hose storage space 2. The nozzle boot arrangement 4 comprises a hose guiding means 9 in order to provide a proper extraction of the hose 7, wherein a vertical centre axis of said nozzle boot 8 substantially coincides with a vertical centre axis of said hose guiding means 9. The hose guiding means 9 comprises a roller. The electronics located in the electrical cabinet, such as means for choosing the desired type of fuel and display means for showing the chosen type of fuel, the volume of dispensed fuel etc, are securely isolated in order to encapsulate electronic components from possible presence of flammable gases. The electronics can also include a payment terminal.
Fig. 2 shows a fuel dispensing unit 1, viewed from the top. Each nozzle boot arrangement 4 is positioned at the front side of a fuel dispensing unit 1 between two vertical profiles 5 and thus the distance between the two profiles 5 is substantially the same as the width of the nozzle booth 8. Because of this mounting of the nozzle boot arrangements 4 in the fuel dispensing unit 1, free space is provided between each nozzle boot arrangement 4 and its opposing profile 5. This space can be used for a retracting mechanism (not shown). Accordingly, in each hose storage space 2, the nozzle boot arrangement 4 is provided on one side of the fuel dispensing unit 1 and a retracting mechanism is provided on the opposite side of the fuel dispensing unit 1. The vertical axis of the retracting mechanism and the vertical axis of said nozzle boot arrangement 4 substantially coincides in a plane parallel to an outer side wall of said fuel dispensing unit 1. The nozzle boot 8 serve as a connecting element between the profiles 5, improving the structural construction of the fuel dispensing unit 1.
In Fig. 3 a first embodiment of a nozzle boot arrangement 4 is shown. The nozzle boot 8 and the hose guiding means 9 is separated from each other. The hose guiding means 9 comprises a roller. When the nozzle boot arrangement 4 is implemented in a fuel dispensing unit 1 the vertical centre axis of said nozzle boot 8 substantially coincides with a vertical centre axis of said hose guiding means 9. However, the hose guiding means 9 can also be mounted in a way where the vertical centre axis of said nozzle boot 8 do not coincide with a vertical centre axis of said hose guiding means 9.
In Fig. 4 a second embodiment of a nozzle boot arrangement 4 is shown. The hose guiding means 9 is attached to the lower end of nozzle boot 8. The hose guiding means 9 can be integral with the nozzle boot 8.
Fig. 5 is a perspective view of a retracting mechanism and nozzle boot arrangement 4 according to a second embodiment. Also, a hose connection 10, wherein a vertical axis of said hose connection and a vertical axis of said nozzle arrangement substantially coincides in a plane parallel to an outer side wall of said fuel dispensing unit, is shown. The retracting mechanism comprises a second guiding means 11, wherein a vertical axis of said second hose guiding means and the vertical axis of said nozzle arrangement substantially coincides in a plane parallel to an outer side wall of said fuel dispensing unit.
The skilled person realises that a number of modifications of the embodiments described herein are possible without departing from the scope of the invention, which is defined in the appended claims.
