## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims priority to International Application No. PCT/GB2013/050074, filed Jan. 15, 2013, and titled “FUEL PUMP SIGN”, the disclosure of which application is incorporated herein by reference.
The present invention relates to a sign for indicating which pumps are currently operational in a petrol station. The invention also relates to a fuel pump system and method for indicating which pumps are currently operational in a petrol station.
Petrol stations usually contain an array of pumps, some of which relate to different fuel types such as unleaded petrol, diesel and higher performance petrol. Typically, either a covering is placed over the handle of a pump to indicate that the pump is currently out of use or a cable tie is used to prevent the handle of the pump that is out of use from being removed. However, it can be difficult or impossible for an approaching driver to determine which of an array of pumps is currently out of use because the covering may be obscured by other parts of the pump array and a cable tie may not be visible from a distance. If the driver requires a particular fuel type, for example diesel, then the driver may mistakenly pull up next to a pump array in which the diesel pump is out of action. This results in wasted time for the driver and reduced revenue for the owner of the petrol station because the pump arrays are not used efficiently.
The above problem becomes more severe as demand for fuel increases. For example, petrol stations can become overcrowded when there is a peak in fuel demand due to industrial action or the threat of a future fuel shortage, with long queues to access pumps. In this situation it is even more important that the pumps are used efficiently, particularly as some pumps are likely to be empty due to the high demand.
Currently, drivers in a queue to access fuel pumps often inadvertently pull up next to a pump that is empty or out of use, or that can only supply the wrong type of fuel. The driver will then attempt to reach a different pump, which may be difficult or impossible due to the queue of drivers behind. Blockages in the flow of vehicles can result, adding to the delay in other drivers reaching the pumps.
According to a first aspect of the present invention, there is provided a fuel pump sign comprising a fuel type indicator panel for indicating the type of fuel supplied by a pump, and a pump availability indicator panel for indicating whether the pump is available for use.

A typical pump array in a petrol station forecourt consists of three double-sided pumps arranged adjacent to each other, making six pumps in total. Each of the double-sided pumps supplies a different grade of fuel, for example standard unleaded petrol, super unleaded petrol and diesel.
A first embodiment of the present invention is a sign 50 designed to be attached to or displayed next to a pump array such as that described above. The sign 50 is displayed so that a driver approaching the pump array can see the sign 50. The sign 50 indicates which of the six pumps is currently in operation, so that an approaching driver can see whether the grade of fuel he requires is available from the pump array and decide whether to pull up at the pump array accordingly. The sign 50 includes a fuel type panel holder 10 as shown in front view in FIG. 1, in rear view in FIG. 2 and in top view in FIG. 3. The sign 50 also includes at least one pump availability panel holder 30, an example of which is shown in front view in FIG. 4 and in top view in FIG. 5. A complete sign 50 consisting of two pump availability panel holders attached to either side of a fuel type panel holder 10 is shown in front view in FIG. 6.
The fuel type panel holder 10 has a rear plate 12, which comprises a sheet of material having two rectangular windows 16 cut out of it. The windows 16 make the sign 50 lighter. An indentation 20 is also formed in the strip of material separating the two windows, the indentation forming a channel connecting one window 16 to the other. In addition, four attachment holes 18 are formed in the strip of material separating the two windows 16, two holes 18 being formed on each side of the indentation 20 as shown in FIG. 1.
Attachment portions 14 having L-shaped cross-sections are formed around three edges of the rear plate 12, as shown most clearly in the perspective view of the sign 50 in FIG. 8. In this embodiment, three attachment portions 14 are formed along each of the left, right and bottom edges of the rear plate 12. The spaces between the attachment portions 14 and the rear plate 12 form slots into which the edges of a fuel type indicator panel 52 can be inserted, so that the fuel type indicator panel 52 is held in position parallel to the rear plate 12 by gravity and the attachment portions 14.
The fuel type indicator panel 52 is a sheet of material, on at least one side of which the name of a grade of fuel is displayed. The name may indicate the type of fuel or may be a brand name. It is preferred that the fuel type indicator panel 52 has two different names displayed on the two sides of the panel. With this feature, the sign 50 can be adapted to display an alternative fuel name by simply lifting the fuel type indicator panel 52 out of the fuel type panel holder 10, reversing the panel 52 and replacing it in the fuel type panel holder 10.
The fuel type panel holder 10 also includes arrow-shaped tabs 22 connected to the top edge of the rear plate 12 and correspondingly shaped channels (not shown) formed in the bottom edge of the rear plate 12. The arrow-shaped tabs 22 can be inserted into the bottom edge channels of the rear plate 12 of another fuel type panel holder 10 so that the two fuel type panel holders are clipped together, one above the other in parallel and in horizontal alignment. In this way, two or more fuel type panel holders can be joined together with fuel type indicator panels indicating the different fuel types available at the pump array to which the sign 50 is attached. Typically, three fuel type panel holders are joined together to indicate the fuel types available at three double-sided pumps in a pump array as described above.
The fuel type panel holder 10 also has channels (not shown) formed in the side edges of the rear plate 12, which are sized and shaped to receive tabs of a pump availability panel holder 30 so as to connect the fuel type panel holder 10 to the pump availability panel holder 30.
The pump availability panel holders 30 of the sign 50 each include a rear plate 32 and attachment portions 34 in the same way as the fuel type panel holders, as shown in FIG. 4. The rear plate 32 of the pump availability panel holder 30 has four rectangular windows 36 formed in it to reduce the weight of the pump availability panel holder 30 while retaining sufficient strength to support the sign 50. The rear plate 32 also includes a trapezoidal cut-out 38 formed in one side edge as shown in FIG. 4. The cut-out 38 allows a pump availability indicator panel 54 held in the pump availability panel holder 30 to be gripped and removed.
The attachment portions 34 of the pump availability panel holder 30 are L-shaped in cross-section and are formed around the top and bottom edges and one side edge of the rear plate 32. The one side edge is the side edge adjacent to the fuel type panel holder 10 as shown in FIG. 8. In this embodiment, three attachment portions 34 are formed along each of those three edges of the rear plate 32. The attachment portions 34 on the top and bottom edges adjacent to the one side edge may be connected to the uppermost and lowermost attachment portions 34 of the one side edge respectively, to form continuous attachment portions 34 having an L-shape in front view. The attachment portions 34 form slots into which the edges of a pump availability indicator panel 54 can be inserted, so that the pump availability indicator panel 54 is held in place parallel to the rear plate 32 by the attachment portions 34.
The pump availability panel holder 30 also includes arrow-shaped tabs 40 similar to those of the fuel type panel holder 10 described above. The tabs 40 extend from the side edge of the rear plate 32 of the pump availability panel holder 30 that has attachment portions 34 formed along it. The arrow-shaped tabs 40 are sized and shaped to form a force fit with the channels formed in the side edges of the rear plate 12 of the fuel type panel holder 10 described above. By inserting the tabs 40 into the channels of the fuel type panel holder 10, the pump availability panel holder 30 can be attached to either side of the fuel type panel holder 10 in parallel and in vertical alignment. Typically, one pump availability panel holder 30 is attached to each side of each fuel type panel holder 10 as shown in FIGS. 6 and 8. Each fuel type panel holder 10 of the sign 50 corresponds to a double-sided pump, and each pump availability panel holder 30 attached to the fuel type panel holder 10 corresponds to one pump of the double-sided pump. For the six pump array described above, the sign 50 would consist of three fuel type panel holders connected vertically, each fuel type panel holder 10 having two pump availability panel holders connected to it making six pump availability panel holders in total.
A pump availability indicator panel 54 is inserted into each pump availability panel holder 30 to indicate whether the corresponding pump is currently operational or out of use. The fuel type indicator panel 52 inserted into the attached fuel type panel holder 10 indicates the fuel type supplied by the corresponding pump. Each pump availability indicator panel 54 has an indication that the pump is operational displayed on one face of the panel and an indication that the pump is out of use displayed on the opposite face of the panel. If a pump is changed from being operational to being out of use or vice versa, the corresponding pump availability indicator panel 54 can simply be removed from the pump availability panel holder 30, reversed and replaced in the pump availability panel holder 30 to indicate this.
The pump availability indicator panels 54 and the fuel type indicator panels 52 can each have a hole formed through them, which allows the panel to be secured to the corresponding holder. The panel may be secured by a cable tie passed through the hole in the panel and through a window of the holder for example.
An example of a sign 50 according to the invention having a fuel type indicator panel 52 and pump availability indicator panels 54 inserted is shown in FIG. 7. The fuel type indicator panel 52 indicates that the fuel type of the corresponding double-sided pump is unleaded. The left pump availability indicator panel 54 indicates that the left hand pump of the double-sided pump is out of use. The right pump availability indicator panel 54 indicates that the right hand pump of the double-sided pump is operational. Using the pump sign 50 of the invention, an approaching driver can instantly see which of the pumps in the pump array are operational and which fuel types are available from that pump array. The driver can also easily decide which side of the double-sided pump array to pull up on to get the required fuel type. Due to the replaceable double-sided indicator panels 54 of the invention, it is quick and straightforward for a pump attendant to alter the sign 50 to correctly indicate which pumps are operational and which fuel types are available from a given pump array.
The sign 50 of the first embodiment can be attached to the pump array by any suitable means, or can be attached to a free-standing support and placed adjacent the pump array. For example, the fuel type panel holder 10 can be bolted or screwed to a surface of the pump array via the attachment holes 18 in the rear plate. The fuel type panel holder 10 may also be strapped to an upright post by a strap passing along the indentation 20 formed in the rear plate 12 of the fuel type panel holder 10 and around the post.
Alternative attachment means include applying adhesive strips to the rear surface of the rear plate 12 of the fuel type panel holder 10. Additional indentations may be formed in the rear surface of the rear plate 12 to accommodate the adhesive strips.
The precise location of the sign 50 relative to the pumps is not important as long as a driver approaching the pumps can see the sign 50. The driver should also be able to determine easily which pumps the sign is associated with.
A second embodiment of a sign according to the invention is shown in FIG. 9. The fuel type panel holder 60 of this sign is designed to hold a fuel type indicator panel 52 and is as described above, other than the different arrangement of attachment holes 68 shown in FIG. 9. The fuel type panel holder 60 of the second embodiment has a rear plate 62, attachment portions 64, windows 66, an indentation 70 and arrow-shaped tabs 72. The sign of this embodiment differs from that described above in that it is semi-electronic. The pump availability panel holders 30 of the sign described above are replaced in this embodiment by light panels 80 as shown in FIG. 9.
The light panels 80 can be connected to the side edges of the fuel type panel holder 60 by any suitable mechanism, for example the arrow-shaped tab and channel arrangement used to connect the pump availability panel holders 30 to the fuel type panel holder 10 in the first embodiment. Each light panel 80 has two lights 82 of different colours, red and green in this example. The green light is switched on to indicate that the corresponding pump is operational and the red light is switched on to indicate that the corresponding pump is out of use. Each light panel 80 is associated with one side of a double-sided pump supplying the fuel type indicated by the fuel type indicator panel 52 in the fuel type panel holder 60, as in the first embodiment.
The light panels 80 preferably use LED lights 82 but may also include incandescent or fluorescent bulbs. The light panels 80 may be powered by a battery or may be connected by any suitable means to the electricity supply of the pump array.
Control over which of the lights 82 on the light panel 80 is illuminated may be provided by a switch on the light panel 80 itself, but preferably the light panels are controlled remotely. For example, the light panels 80 may have wired or wireless control connections to a computer system at the counter of the petrol station shop. With this arrangement, an attendant can select which light 82 of each light panel 80 is illuminated from the computer system in the shop to ensure that the light panels 80 correctly indicate whether the associated pump is available for use.
A third embodiment of the invention is shown in FIG. 10, which illustrates a fully electronic sign 90. The sign 90 in this embodiment consists of an electronic display such as an LCD or LED panel. The sign 90 is attached to or located near to a pump array in the same way as the signs of the first and second embodiments. The electronic display contains a display area 92, 94 corresponding to each double-sided pump. Each display area contains a first sub-area 92 indicating the type of fuel supplied by the associated double-sided pump and second and third sub-areas 94, each of the second and third sub-areas 94 indicating whether one side of the double-sided pump is operational or out of use. In this example, the display areas 92, 94 are each arranged to have a similar appearance to the semi-electronic sign of the second embodiment, with a central first sub-area 92 displaying the fuel type and second and third sub-areas 94 on either side of the first sub-area 92 displaying a red or green light 96 depending on whether the pump is out of use or operational.
In the third embodiment, the electronic display may also have an additional information display area 98, shown at the bottom of the sign in FIG. 10. This display area 98 can be used to display additional information of interest to drivers, for example traffic and weather information. This display area 98 may also be used to display advertising.
The foregoing description has been given by way of example only and it will be appreciated by a person skilled in the art that modifications can be made without departing from the scope of the present invention.
