Technical field
[0001] 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
[0002] 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.
[0003] 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.
[0004] 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.
[0005] 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.
[0006] 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.
[0007] 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.
[0008] 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.
Summary of the invention
[0009] In view of the foregoing, it is an object of the present invention to provide a more
efficient and space effective fuel dispensing unit.
[0010] This and other objects and advantages that will be apparent from the following description
of the present invention are achieved according to a first aspect of the invention
by a nozzle boot arrangement, comprising a nozzle boot for holding a nozzle. The nozzle
boot arrangement is
characterised in that said nozzle boot arrangement is adapted to be positioned at the front side of a fuel
dispensing unit between two vertical profiles. This is advantageous in that the profiles
in the fuel dispensing unit will be unoccupied and space for arranging other means
needed for proper handling of a hose is provided. Also, the width of the profiles
do not control the width of the nozzle boot.
[0011] The nozzle boot arrangement may further comprise a hose guiding means for guiding
a hose connected to said nozzle, wherein a vertical axis of said nozzle boot substantially
coincides with a vertical axis of said hose guiding means. This is advantageous in
that the hose is guided by said hose guiding means in order to provide a proper extraction
of the hose.
[0012] A vertical centre axis of said nozzle boot may substantially coincide with a vertical
centre axis of said hose guiding means. This is advantageous in that the hose handled
by a retracting mechanism arranged on a profile opposite to the nozzle boot will be
extracted straight out of the fuel dispensing unit. No lateral displacement of the
hose occur.
[0013] The hose guiding means may be attached to one end of the nozzle boot, which is advantageous
in that the nozzle boot may be manufactured in a simpler and more cost-effective way.
[0014] The hose guiding means may be attached to a lower end of the nozzle boot, which is
advantageous in that the nozzle boot may be manufactured in a simpler and more cost-effective
way.
[0015] The hose guiding means may be integral with the nozzle boot, which is advantageous
in that the nozzle boot may be manufactured in a simpler and more cost-effective way.
[0016] The hose guiding means may comprise a roller, which is advantageous in that the hose
guiding means may be manufactured in a simpler and more cost-effective way.
[0017] The distance between the two profiles may be substantially the same as the width
of the nozzle booth, which is advantageous in that the width of the entire fuel dispensing
unit may be decreased.
[0018] According to a second aspect of the invention, a fuel dispensing unit comprising
a nozzle boot arrangement according to the first aspect of the invention is provided.
[0019] The fuel dispensing unit may further comprise at least one vertical profile, which
together with the opposing nozzle boot arrangement defines a hose storage space in
said fuel dispensing unit. This is advantageous in that the width of said hose storage
space may be decreased.
[0020] The lateral distance between two profiles may be substantially the same as the width
of the nozzle boot, which is advantageous in that the width of the entire fuel dispensing
unit may be decreased.
[0021] The hose storage space may further comprise at least one hose connection, 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. Accordingly, no lateral displacement of the hose will occur inside the fuel
dispensing unit as well as outside the fuel dispensing unit.
[0022] The hose storage space may further comprise at least one second hose guiding means,
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. Accordingly, no bending of the hose will occur
inside the fuel dispensing unit as well as outside the fuel dispensing unit.

Detailed description of preferred embodiments
[0024] 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.
[0025] 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.
[0026] 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.
[0027] 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.
[0028] 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.
