Technical field
[0001] The present invention relates to a device for handling a hose, which device allows
the hose to be pulled out from a front opening of a hose storage space and which device
is adapted to return the hose to the hose storage space, said device comprising a
first hose guiding means that is movably arranged in the hose storage space and is
adapted to move in a substantially vertical direction between an idle position in
the upper portion of the hose storage space and an operating position in the lower
portion of the hose storage space. Further, the present invention relates to a fuel
dispensing unit comprising a device for handling a hose.
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 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] One way of facilitating access to the petrol pump is to provide it with a longer
hose. This may, however, cause problems since a longer hose may tend to land on the
ground when not used and thus get stuck in or be damaged by passing cars or other
vehicles. To prevent this, the column may be provided with some kind of returning
mechanism for the hose.
[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 devices described above is their size, or
their extension within respective hose housings, which results in bulky and complicated
structures.
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 way for handling a hose.
[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 device for handling a hose, which device allows the hose to be pulled out from
a front opening of a hose storage space and which device is adapted to return the
hose to the hose storage space, said device comprising a first hose guiding means
that is movably arranged in the hose storage space and is adapted to move in a substantially
vertical direction between an idle position in the upper portion of the hose storage
space and an operating position in the lower portion of the hose storage space. The
device is characterised by a second hose guiding means that is fixedly arranged in
the lower portion of the hose storage space. This is advantageous in that a robust
and space-saving device is provided, which enables a smooth and flexible handling
of the hose.
[0011] The first hose guiding means may have a shaft connecting it to said hose storage
space by means of grooves on either side of the first hose guiding means, whereby
the first hose guiding means is pivotable and movable in said grooves. This is advantageous
in that the hose is prevented from moving in a lateral direction in the hose storage
space. Thus, problems regarding hoses and cables getting entangled with each other
within the hose storage space are eliminated.
[0012] A spring element may be arranged to move the first hose guiding means from the operating
position to the idle position, which is advantageous in that a simple construction
is utilized.
[0013] One end of the spring element may be attached to the lower portion of the device,
the second end of the spring element is attached to the first hose guiding means,
and the spring element is guided by a guiding component arranged at the upper portion
of the device. This is advantageous in that a relatively long spring element is used,
thereby enabling a relatively long extension of the spring element.
[0014] The second end of the spring element may be connected to the first guiding means
at a predetermined distance from a side wall of the hose storage space in a forward
direction in relation to a hose extraction direction. This is advantageous in that
a greater width of the hose storage space is used.
[0015] The spring element may be a rubber band, which is advantageous in that it comprises
suitable elastic characteristics.
[0016] The first hose guiding means may comprise a roller, which is advantageous in that
the first hose guiding means may be manufactured in a simpler and more cost-effective
way.
[0017] The second hose guiding means may comprise a roller, which is advantageous in that
the second hose guiding means may be manufactured in a simpler and more cost-effective
way.
[0018] The roller of the second hose guiding means may be rotatable about a hollow shaft,
and the hollow shaft is adapted to receive pipes or electrical cables, which is advantageous
in that said pipes and electrical cables will not risk getting entangled with each
other or with other elements within the hose storage space.
[0019] The hose connection may be arranged in the lower portion of the hose storage space,
which is advantageous in that nearly the entire hose can be pulled out of the hose
storage space, giving the customer a possibility to use a greater part of the hose
length.
[0020] The guiding component may comprise a rotating means which is advantageous in that
the spring element is guided in an efficient manner.
[0021] The first hose guiding means may comprise a first roller being rotatable around a
first shaft, a second roller being rotatable around a second shaft and a sleeve located
between said first and second roller and adapted to enclose the hose. This is advantageous
in that the hose is prevented from derailing from the hose guiding means thereby ensuring
a more secure handling of the hose.
[0022] The first hose guiding means may comprise a foldable arm, which is advantageous in
that the hose will be prevented from moving in a lateral direction.
[0023] The second hose guiding means may comprise a guide bar, which is advantageous in
that the second hose guiding means may be manufactured in a simpler and more cost-effective
way.
[0024] A guiding sleeve may be arranged at the second hose guiding means to enclose the
hose and guide it into engagement with the second hose guiding means. This is advantageous
in that the hose is prevented from derailing from the second hose guiding means thereby
ensuring a more secure handling of the hose.
[0025] The second hose guiding means may be arranged forward of the first hose guiding means
in the hose storage space, which is advantageous in that the hose is kept within the
hose storage space before it exits from the second hose guiding means.
[0026] According to a second aspect of the invention, a fuel dispensing unit comprising
a device for handling a hose according to the first aspect of the invention is provided.

Detailed description of preferred embodiments
[0028] Fig. 1 shows a fuel dispensing unit 1, having eight hose storage spaces 2, an electrical
cabinet 3 containing all the electronics for the fuel dispensing unit 1, a hydraulic
cabinet 4 containing fuel dispensing means (not shown), e.g. fuel metering means,
valves, vapour recovery system etc, and a column 5 extending vertically between and
separating the electrical cabinet 3 and the hydraulic cabinet 4 from the hose storage
spaces 2. 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
4, and from there to the column 5 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. The hose 7 is handled by a hose handling
device 8 according to the invention, which is arranged in every hose storage space
2. The electronics located in the electrical cabinet 3, 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.
[0029] Fig 2 shows a device 8 for handling a hose 7 according to a first embodiment of the
first aspect of the invention.
[0030] In Fig. 3a, a device 8 for handling a hose 7 is shown, when said hose 7 is in a retracted
position. The device 8 which is located in a storage space 2 comprises a first hose
guiding means 9, a second hose guiding means 10, a hose connection 11, a spring element
12 and a guiding component 13. The first hose guiding means 9 has a shaft 14 connecting
it to said hose storage space 2 by means of grooves 15 on either side of the first
hose guiding means 9, whereby the first hose guiding means 9 is pivotable and movable
in a substantial vertical direction. The first hose guiding means 9 comprises a first
roller 16 being rotatable around a first shaft 17, a second roller 18 being rotatable
around a second shaft 19 and a sleeve 20 located between said first and second roller
16, 18 and adapted to enclose the hose 7. When the hose 7 is in its retracted position
the first hose guiding means 9 is located in the upper portion of the hose storage
space 2. The second hose guiding means 10 comprises a roller and is fixedly arranged
in the lower portion of the hose storage space 2. The roller of the second hose guiding
means 10 is rotatable about a hollow shaft 21, and the hollow shaft 21 is adapted
to receive pipes or electrical cables. The second hose guiding means 10 is arranged
forward of the first hose guiding means 9 in the hose storage space 2. The hose connection
11 is arranged in the lower portion of the hose storage space. The spring element
12 is arranged to move the first hose guiding means 9 from the operating position
to the idle position. One end of the spring element 12 is attached to the lower portion
of the hose storage space 2 and the second end of the spring element 12 attached to
the first hose guiding means 9. The spring element 12 is guided by the guiding component
13 which is arranged at the upper portion of the hose storage space 2. The guiding
component 13 comprises a rotating means 22, such as a roller.
[0031] Fig. 3b shows the device 8 for handling a hose 7, when said hose 7 is in an extracted
position. The first hose guiding means 9 is located in the lower part of the hose
storage space 2 below the second hose guiding means 10 when the hose 7 is fully extracted.
The spring element 12 is extended and applies a force upwards in a vertical direction
on the first hose guiding means 9 and thus also on the hose 7.
[0032] In Fig. 4, an alternative embodiment of the second hose guiding means 10 is shown.
In this embodiment, the second hose guiding means 10 comprises a guide bar.
[0033] Fig. 5 shows another embodiment of the device 8 for handling a hose 7 according to
the first aspect of the invention. In this embodiment, the first guiding means 9 comprises
a roller. A line drawn from the shaft 14 connecting the roller to the hose storage
space 2 and the shaft carrying the roller creates an angle α together with the adjacent
wall of the hose storage space 2. When the first hose guiding means 9 is in the idle
position, the angle α preferably lies in a range between 45 and 120 degrees and is
more preferably about 90 degrees. However, when the first hose guiding means 9 move
downward from the idle position towards the operating position, the angle α decreases
rapidly. Accordingly, when the angle α has decreased a certain amount, the hose 7
will abut against the adjacent side wall of the hose storage space 2 and be pressed
between said side wall and the first hose guiding means 9. Thus, the hose 7 helps
preventing the first guiding means 9 from lateral movement. As shown in Fig. 5, the
second hose guiding means 10 may be attached to the lower end of the nozzle boot.
Also, the second hose guiding means 10 may be integral with the nozzle boot.
[0034] The first hose guiding means 9 is maintained in the idle position by means of the
spring element 12, due to the fact that the weight of the first hose guiding means
9 together with the weight of the hose 7 is not sufficient enough to stretch the spring
element 12. Accordingly, when the first hose guiding means 9 is in its idle position,
the hose 7 is in a retracted position. In the retracted position, the hose 7 extends
upwards from the hose connection 11, over the first hose guiding means 9, and downwards
under the second hose guiding means 10.
[0035] When a user pulls the hose 7, the pulling force will cause the first hose guiding
means 9 to move downward from the idle position as shown in Fig. 3b, thereby extending
the spring element 12. The first hose guiding means 9 slides vertically in a downward
direction in the grooves 15 in the hose storage space 2. When the hose 7 is in its
extracted position, the first hose guiding means 9 is in its operating position and
the hose 7 extends from the hose connection 11, over the first hose guiding means
9, and under the second hose guiding means 10.
[0036] When the user releases the pulling force on the hose 7, the spring element 12 will
contract and consequently, the first hose guiding means 9 will be allowed to slide
vertically in an upward direction in the grooves 15 in the hose storage space 2 to
the idle position.
[0037] The components in the device 8 for handling a hose 7 and in the fuel dispensing unit
1 comprising such device 8 may vary in many different ways regarding size and shape.
[0038] The spring element may be of any type known per se, such as a rubber band, a coil
spring or a gas spring. Moreover, the spring element may be a line reel or a rotating
wheel connected to a spring. In one embodiment, one end of the spring element 12 may
be attached to the upper portion of the hose storage space 2 and the other end directly
to the first hose guiding means 9.
[0039] The spring element 12 may also be attached to other places within the hose storage
space 2. In one embodiment the spring element 12 is connected to the hose storage
space 2 next to the second hose guiding means 10 or at the bottom of the hose storage
space 2. The spring element 12 then runs in a vertical direction to a first upper
corner of the hose storage space 2 and over a first guiding component located in this
first upper corner, along the top of the hose storage space 2 to a second upper corner
of the hose storage space 2 and over a second guiding component located in this second
upper corner, in order to connect with the first hose guiding means 9. Also, one end
of the spring element 12 may be attached to the upper portion of the hose storage
space 2 and the other end of the spring element 12 to the first hose guiding means
9.
[0040] The first hose guiding means 9 may be a roller and the second hose guiding 10 means
may be a roller or a guide bar. In one embodiment, a guiding sleeve is arranged at
the second hose guiding 10 means to enclose the hose 7 and guide it into engagement
with the second hose guiding means 10.
[0041] In Fig. 6a-6c, yet another embodiment of the device 8 for handling a hose 7 according
to the first aspect of the invention is shown. In this embodiment, the first hose
guiding means 9 is a foldable arm which is connected to the hose 7 by means of a sleeve.
A spring element 12 is attached between the sleeve and the hose storage space 2. When
a user pulls the hose 7, the pulling force will at first cause the foldable arm to
fold and then to follow the hose 7 in a substantially vertical direction towards the
second hose guiding means 10, thereby extending the spring element 12. When the user
releases the pulling force on the hose 7, the spring element 12 will contract and
consequently, the foldable arm will return to its idle position. The fuel dispensing
unit 1 can be equipped with a various number of storage spaces 2 comprising the device
8 for handling a hose 7. However, in the preferred embodiment of the present invention
the fuel dispensing unit 1 comprises eight hose storage spaces 2, four on each opposing
side, and thus eight devices 8 for handling eight hoses 7, four on each opposing side.
