Description

CROSS REFERENCE TO RELATED APPLICATIONS

This application is a national application of Swedish Patent Application No. 1450622-4 filed on May 26, 2014 and entitled “Device for Handling a Hose and a Fuel Dispensing Unit Having Such a Device,” the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The field of the invention generally relates to the field of fuel dispensing units and more particularly to a device for handling a hose.

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 or frame 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 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 maneuvering 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.

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 or frame may be provided with some kind of returning mechanism for the hose.

A problem common for the hose returning devices described above is their size, or their extension within the fuel dispensing unit, which results in bulky and complicated structures.

SUMMARY

Embodiments of the invention include a device for handling a hose and a fuel dispensing having such a device.

Such embodiments generally aim at eliminating or at least reducing the problems discussed above as well as other problems known in the art.

In one embodiment, a device for handling a hose comprises a frame element, said frame element being hollow and including a guiding element, a hose guiding means arranged outside of said frame element and adapted to guide said hose, and an elastic element which is attached to a fixed point in relation to said frame element at one end and to said hose guiding means at the other end. The device is characterized in that said elastic element is adapted to extend within said frame element and to be guided by said guiding element, and that said hose guiding means is movable away from said frame element allowing said hose to be pulled from an idle position to an operating position when said elastic element is extended. This is advantageous in that a robust and space-saving device is provided, which enables a smooth and flexible handling of the hose. Further, due to the design of the frame element and the guiding element included therein, the risk of entangling with the hose is eliminated.

According to another aspect a fuel dispensing unit comprises such a device for handling a hose.

DETAILED DESCRIPTION

FIG. 1 illustrates a fuel dispensing unit 1 having a device 2 for handling a hose 3 provided on each side of the fuel dispensing unit 1. The fuel dispensing unit 1 has an electrical cabinet 4 containing all the electronics for the fuel dispensing unit 1, a hydraulic cabinet 5 containing fuel dispensing means (not shown), e.g. fuel metering means, valves, vapour recovery system etc, and a column 6 (on each side of the fuel dispensing unit 1) extending upwards vertically above the electrical cabinet 5. The fuel dispensing unit 1 is connected to an underground reservoir (not shown) containing fuel. When filling up the tank of a motor vehicle, the fuel is pumped from the underground reservoir by means of a pump (not shown) which is located in the hydraulic cabinet 4, and from there to a hose connection (not shown) and out to a nozzle 7 via the hose 3.

In FIG. 2a, the device 2 is illustrated when the hose 3 (both of the hoses 3) is in an idle position. In this exemplary embodiment, the device 2 is arranged to handle two hoses 3. The device 2 comprises a frame element 8 which is hollow and includes a first, second, third and fourth guiding element 9, 10, 11, 12. Each guiding element comprises a roller which is rotatable around an axis. The device 2 further comprises a first and second elastic element 13, 14, and a first and second hose guiding means 15, 16. The frame element 8 comprises first and second side parts 17, 18 which are constituted the columns 6 provided on each side of the fuel dispensing unit 1, and a top part 19. The top part 19 extends in a horizontal direction and connects the first and second side parts 17, 18 at an upper end 20, 28 of the first and second side parts 17, 18, respectively. The frame element 8 further comprises a support element 23 arranged horizontally between the first and second side parts. The first elastic element 13 is attached to a first fixed point P₁ at one end and to the first hose guiding means 15 at the other end. The first elastic element 13 is adapted to extend from the first fixed point P₁, upwards vertically through the first side part 17 to a first outer end 21 of the top part 19, over the first guiding element 9 which is arranged at the first outer end 21 of the top part 19, horizontally through the top part 19 to a second outer end 22 of the top part 19, over the second guiding element 10 which is arranged at the second outer end 22 of the top part 19, out of the frame element 8 and to the first hose guiding means 15. The first hose guiding means 15 is thereby movable away from the frame element 8 allowing the hose 3 to be pulled from an idle position to an operating position when the first elastic element 13 is extended. The first hose guiding means 15 is adapted to enclose the hose 3 and is arranged adjacent to the second outer end 22 of said top part 19 when the hose 3 is in said idle position. Thus, the hose 3 is not accommodated in the frame element 8 and does not form part of the device 2. Instead, the hose 3 is held in place on the side of the fuel dispensing unit 1 by means of the hose guiding means 15. The second elastic element 14 is attached to a second fixed point P₂ at one end and to the second hose guiding means 16 at the other end. The second elastic element 14 is adapted to extend from the second fixed point P₂, upwards vertically through the second side part 18 to the second outer end 22 of the top part 19, over the third guiding element 11 which is arranged at the second outer end 22 of the top part 19, horizontally through the top part 19 to a first outer end 21 of the top part 19, over the fourth guiding element 12 which is arranged at the first outer end 21 of the top part 19, out of the frame element 8 and to the second hose guiding means 16. The second hose guiding means 16 is thereby movable away from the frame element 8 allowing the hose 3 to be pulled from an idle position to an operating position when the second elastic element 14 is extended. The second hose guiding means 16 is adapted to enclose the hose 3 and is arranged adjacent to the first outer end 21 of said top part 19 when the hose 3 is in said idle position.

In FIG. 2b, the device 2 is illustrated when one of the hoses 3 (on the left side of the fuel dispensing unit 1) is in an operating position.

FIG. 3 illustrates the device 2 according to a second embodiment of the invention. In this embodiment, the device 2 is arranged to handle two hoses 3 and the frame element 8 further comprises a fifth and a sixth guiding element 24, 25. The first elastic element 13 is attached to a third fixed point P₃ (located at the first outer 21 end of the top part 19) at one end and to the first hose guiding means 15 at the other end. The first elastic element 13 is adapted to extend from the third fixed point P₃, downwards vertically through the first side part 17 to a lower end 26 of the first side part 17, below the fifth guiding element 24 arranged at the lower end 26 of the first side part 14, upwards vertically through the first side part 17 to the first outer end 21 of the top part 19, over the first guiding element 9 arranged at the first outer end 21 of the top part 19, horizontally through the top part 19 to the second outer end 22 of the top part 19, over the second guiding element 10 arranged at the second outer end 22 of the top part 19, out of the frame element 8 and to the first hose guiding means 15. The second elastic element 14 is attached to a fourth fixed point P₄ (located at the second outer 22 end of the top part 19) at one end and to the second hose guiding means 16 at the other end. The second elastic element 14 is adapted to extend from the fourth fixed point P₄, downwards vertically through the second side part 18 to a lower end 27 of the second side part 18, below the sixth guiding element 25 arranged at the lower end 27 of the second side part 18, upwards vertically through the second side part 18 to the second outer end 22 of the top part 19, over the third guiding element 11 arranged at the second outer end 22 of the top part 19, horizontally through the top part 19 to the first outer end 21 of the top part 19, over the fourth guiding element 12 arranged at the first outer end 21 of the top part 19, out of the frame element 8 and to the second hose guiding means 16.

When the hose 3 is to be used to refuel a vehicle, the hose 3 is merely pulled by a user. The hose guiding means 15, 16 will follow the hose 3 and move away from the frame element 8 to an operating position, thereby extending the elastic element 13, 14 attached to the same. When the vehicle has been refueled and the user releases the pressure applied to the hose 3, the elastic element 13, 14 will pull the hose guiding means 15, 16 as well as the hose 3 back to the idle position.

The skilled person realizes 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.

For instance, elastic element can be made of any suitable material, such as a rubber band, a spring wire, wire connected to a spring, and a roll of spring-loaded coiled wire.

The hose guiding means can be of any suitable shape and size. In one embodiment of the hose guiding means, the hose can slide freely through the same during use.

The guiding elements can be of any suitable shape and size and are not limited to rollers. The guiding element can, for example, be made of low friction materials and be shaped as a curved groove in which the hose can slide.

The fixed point can be located at any suitable location, both within and outside of the device as well as the fuel dispensing unit.
