Description

DEVICE AND |\/IETHOD FOR HANDLING AT LEAST ONE HOSE Technical field The invention relates to a device and method for handling at least onehose.

Background artA fuel dispensing unit, such as a petrol pump typically comprises a pump part standing on the ground, a display part positioned above the pumppart and showing the chosen type of petrol, cash readout, volume readoutetc., 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 vehiclebeside the petrol pump and opens the cover or cap of the petrol tank. Thedriver then selects the desired type of petrol and places the pump nozzle inthe 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 hosedoes not reach to the vehicle if parked a distance from the petrol pump. Thereason why the vehicle has not been parked sufficiently close to the pumpmay be difficulty in maneuvering owing to a limited space round the petrolpump. To allow the hose to reach the vehicle, it is usually necessary for thedriver to park his vehicle so that the side of the vehicle where the filler cap ispositioned faces the petrol pump. lt is not always known to a driver of anunfamiliar 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 sideof the pump and thus not being able to fill up the tank without moving thevehicle to the other side of the petrol pump since the hose does not reach allthe way round the vehicle.

One way of facilitating access to the petrol pump is to provide it with alonger hose. This may, however, cause problems since a longer hose maytend to land on the ground when not used and thus get stuck in or bedamaged by passing cars or other vehicles. To prevent this, the fuel dispensing unit may be provided with some kind of returning mechanism forthe hose.

US 6 328 060 discloses a gasoline dispensing unit and methodaccording to which one end of a cord is attached to a dispensing hose tosupport the hose relative to a dispenser unit during non-use. The other end ofthe cord is attached to a drum having a tapered outer surface and acontinuous spiral groove. When the hose is not in use, the cord is wound onthe drum from the largest-diameter drum portion to the smallest-diameterportion. The cord thus unwinds from the drum from its smallest-diameterportion to the largest-diameter portion when the hose is pu||ed from thehousing to provide a mechanica| advantage and reduce the required pu||ingforce.

GB 782 882 discloses a swinging arm hose retriever for f|uiddispensing apparatus. The hose of the f|uid dispensing apparatus is retractedby a spring drum which, together with a spring-biased swinging arm, ismounted on a cover replacing the normal cover for the usua| aperture in thetop of the dispensing cabinet. The cover carries a support from which aspindle and a frame carrying the arm are supported by bearings. A springconnected to a fork pivoted to the spindle biases the arm to its normalposition.

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

Another problem with the hose returning devices existing of the markettoday is that the force required for extracting the hose from the hose housing is quite extensive.

The rocker returning means may comprise a spring element.

The first hose guiding means may comprise a rail element to supportthe hose which, to allow pulling out and returning of the hose, is movable inrelation to the hose storage space between in the idle position and theworking position.

The rail element may be adapted to be moved towards the workingposition when pulling out the hose and, when returning the hose, be movedtowards the idle position.

The sensor means may be connected to a movable portion an outerhousing of the hose storage space, and the control unit is configured totrigger extraction of the cable element by means of the motor or to trigger aneutral state of the motor when movement of the movable portion of the outerhousing, in a direction away from the outer housing, is detected.

The sensing means may further comprise a further sensor configuredto detected movement of the second hose guiding means, and the control unitis configured to stop the motor when the second hose is in a bottom positionwithin the hose storage space.

The extraction of the cable element by means of the motor may beconducted for a predetermined length of the cable element.

The extraction of the cable element by means of the motor may bebased on a motor driving power calculated by the control unit.

According to a second aspect, these and other objects are achieved, infull or at least in part, by a method for handling at least one hose in a fueldispensing unit, to allow the at least one hose to be pulled out from a frontopening of a hose storage space and to return the at least one hose to thehose storage space. The method comprises the steps of providing a first hoseguiding means and a second hose means movable between an idle positionand a working position to control extraction and feeding in of the hose, andarranging a sensor means in hose storage space. The method ischaracterized by the step of controlling a motor, connected to the secondhose guiding means through a cable element, by means of a control unit,connected to the sensor means and to the motor, based on detectedmovements of the first hose guiding means. lt should be noted that the different embodiments of the device that isdescribed above are exemplifying only. The embodiments may be combinedwith each other in any suitable way depending on the requirementsestablished for the fuel dispensing unit and on how many hoses the device ishandling.
