## Background
TECHNICAL FIELD
The presently disclosed subject matter relates to an anti-theft device used with fuel dispensers. Specifically, the disclosed anti-theft devices include a lock feature that prevents access to the dispenser pulsar. Methods of making and using the disclosed anti-theft device is also included.
BACKGROUND
As fuel prices continue to rise, small businesses and global enterprises find themselves paying more for nearly every input and service needed to bring their products to market. In response, consumers have had to adjust because they must pay more at the grocery store, shopping malls, and to fill up their vehicle gas tanks. Moreover, as fuel prices continue to rise, the incentive to steal fuel becomes greater. In regions of the United States, for example, fuel theft has become a significant cost to gas station owners. To counter the problem of fuel theft, gas stations frequently install one or more exterior monitoring cameras that enable the detection of an offender when fuel thefts occurs. However, security cameras are costly to purchase, and monitoring of cameras require ongoing fees. In addition, when stolen vehicles or false license plates are used by the thief, the cameras are ineffective at identifying the offender. Even at gas stations that require pre-payment, thieves have figured out ways to steal gas. For instance, magnets positioned on an exterior surface can manipulate a gas pump in order to trick the pump into allowing a user to indiscriminately dispense as much gas as possible while charging them for only a small fraction of the gasoline. Further, with current gas dispenser and gas station layouts, an attendant may never know theft has begun or occurred, even when security cameras are in use. It would therefore be beneficial to provide a device that overcomes the shortcomings of the prior art. It would further be beneficial to provide a device that prevents and/or deters theft of gasoline at the pump.

The presently disclosed subject matter is directed to a pulsar lock device that can be installed on a variety of different gas dispensing pumps to prevent theft of gasoline. The term “pulsar” refers to an element present within the interior of a gas dispenser that regulates the flow of the fuel. A “pulsar block” therefore refers to a device that blocks the manipulation of the pulsar using any suitable method, such as (but not limited to) blocking access to the pulsar control panel. The term “gas dispenser” refers to any of a wide variety of pumps that dispense gasoline into a vehicle. As shown in FIG. 1, pulsar lock device 5 includes first and second covers 10, 11 that enable the device to be attached to a fuel dispenser frame. The covers also properly position the device adjacent to the pulsar, as described in detail below. The pulsar lock further includes cross bar 15 that spans the distance between the first and second covers and provides support for block 20. Advantageously, the block is positioned adjacent to the pulsar, thereby preventing access to the pulsar control board. As a result, the pulsar cannot be accessed and/or manipulated, thereby effectively preventing theft of gasoline by thieves.
A set forth above, pulsar lock device 5 includes a pair of covers 10, 11. FIG. 2a illustrates one embodiment of a cover that can be used with the disclosed pulsar lock device. As shown, each cover can be configured planar in design with front edge 25, opposed rear edge 26, outer edge 27, and inner edge 28. The term “inner edge” refers to the device edge that faces a pulsar when installed. The term “outer edge” refers to the device edge that faces away from the pulsar when installed. Each cover further includes top face 30 and opposed bottom face 31, as shown in FIG. 2b. 
Each cover inner edge 26 includes cut-out 29 that is sized and shaped to accommodate a dispensing pump printer. Each cut-out can be configured in any suitable size and shape. In some embodiments, each cover includes a cut-out positioned on the inner edge about one-third of the total length of the cover from the first or second end. It should be appreciated that the presently disclosed subject matter also includes embodiments where the covers lack the printer cut-out 29 and other techniques are used to accommodate a dispenser printer.
Covers 10, 11 can be configured in any desired shape, such as (but not limited to) rectangular, square, and the like. It should be appreciated that any shape can be used.
As shown in FIGS. 2b-2d, each cover 10, 11 includes arms 35 extending upwards away from top face 30 at each of the front and rear edges. In some embodiments, the arms are horizontal relative to the top face of each cover. In other embodiments, the arms can be angled relative to the top face of each cover. The arms allow each end of the cover to attach to a corresponding fuel dispenser frame. The arms can attach using any suitable method, such as (but not limited to) the use of mechanical elements (bolts, screws, fasteners, staples, clips, and the like), welding, adhesive, magnets, etc. Each arm can have length 12 of about 0.5-5 inches (e.g., at least/no more than about 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, or 5 inches). It should be appreciated that the length of the arms can be greater or less than the range given above.
Each frame further includes lip 40 that extends in a downward direction from the bottom face at outer edge 27. In some embodiments, each lip is about perpendicular relative the bottom face of each cover. In other embodiments, the lip can be angled relative to the bottom face of each cover. The lip can have the same length as a corresponding cover in some embodiments. In other embodiments, the lip can have a length that is about 50, 60, 70, 80, 90, or 99 percent of the length of the corresponding cover. Each lip can include width 13 of about 0.1-5 inches (e.g., at least/no more than about 0.1, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, or 5 inches). It should be appreciated that the width of the lip can be greater or less than the range given above. Each lip can have a thickness of about 0.1-2 inches in some embodiments.
As illustrated in FIG. 2e, each cover includes length 45 of about 20-60 inches in some embodiments. Thus, each cover can have a length of at least about (or no more than about) 20, 25, 30, 35, 40, 45, 50, 55, or 60 inches. The term “length” refers to the longest straight-line distance between first and second ends 25 and 26. Each cover can also have width 46 of about 2-10 inches (e.g., at least/no more than about 2, 3, 4, 5, 6, 7, 8, 9, or 10 inches). The term “width” refers to the longest straight line distance perpendicular to the length (e.g., the distance between the cover inner and outer edges). The cover can include a thickness of about 0.1 to 2 inches (e.g., at least/no more than about 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9 or 2 inches). The term “thickness” refers to the longest vertical distance between the top and bottom faces of the covers. It should be appreciated that the length, width, and thickness of each cover can be greater or less than the ranges given herein.
As noted above, the first and second covers are linked together via cross bar 15 positioned adjacent to the top face of each cover, as shown in FIG. 3a. The cross bar therefore functions to join the covers together and acts as a support surface for block 20. Each cross bar includes first and second ends 50, 51 with length 52 therebetween. The length of each crossbar can be about 2-15 inches (e.g., at least/no more than about 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, or 15 inches). Each cross bar can include width 53 of about 0.1-5 inches (e.g., at least/no more than about 0.1, 0.2, 0.3, 0.4, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, or 5 inches). Each cross bar can further include a thickness of about 0.1 to 2 inches (e.g., at least/no more than about 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9 or 2 inches). The “thickness” of each cross bar is the longest vertical distance from a cross bar top face to a bottom face. It should be appreciated that the length, thickness, and width of each cross bar can be configured to be greater or less than the ranges given above.
In some embodiments, cross bar 15 is joined to the top face of covers 10, 15 using keepers 55, as shown in FIG. 3b. The term “keeper” can refer to any element that allows for permanent or releasable attachment of the crossbar to the covers. Suitable keepers can include (but are not limited to) bolts, screws, joints, staples, magnets, adhesives, welding, and the like. Any method that can permanently or removably attached a cross bar to the covers can be used.
It should be appreciated that in some embodiments, device 5 includes a single cross bar 15. However, it is envisioned that the disclosed device can include any number of cross bars, such as to provide added support to the device.
The cross bar also functions to support block 20, as noted above. Specifically, cross bar 15 supports the weight of the block and properly positions the block at a suitable location relative to a dispenser pulsar. As shown in FIGS. 4a-4c, support block 20 extends upward from the cross bar, between the first and second covers. In some embodiments, the support block is about perpendicular relative to the cross bar. The support block includes first face 60 that is positioned against the dispenser pulsar when in use. In some embodiments, first face 60 is directly adjacent (e.g., contacting) the control face of the pulsar. In other embodiments, the first face is adjacent to the control face of the pulsar (e.g., positioned next to but not directly touching). The control face of the pulsar can include circuitry and any elements that can be accessed to manipulate the flow of gasoline from the dispenser pump.
First face 60 is solid, allowing it to rest adjacent and flush with the control panel, as illustrated in FIG. 4d. Opposed second side 61 of the support block is concave with an interior that extends into the center of the support block, as shown in FIG. 4e. Second side 61 can extend inward with a thickness of about 0.1-2 inches (e.g., at least/no more than about 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 1.1, 1.2, 13, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, or 2 inches).
The block can have length 65 and/or height 66 of about 2-15 inches (e.g., at least/no more than about 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, or 15 inches). The block can further include thickness 67 of about 0.5-5 inches (0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, or 5 inches). However, it is to be understood that the length, width, and thickness of block 20 is not limited to the ranges given herein.
Support block 20 can be configured in any desired shape, so long as it blocks the pulsar control panel. Thus, the support block can be configured in a square, rectangular, trapezoidal, or any shape. In some embodiments, one face of the support block can taper as shown in the embodiment of FIG. 4b to correctly lie flush against the control panel.
The disclosed device 5 can be constructed from any suitable material, such as (but not limited to) metal (e.g., steel, stainless steel). Any suitable method can be used to construct the disclosed device, including the use of welding, thermoforming, and other known methods.
In use, device 5 can be assembled on a standard fuel dispenser at a typical gas station. For example, the gas pumps can be Gilbarco Encore 500TM and Encore 700TM series dispensers. Any medium or low flow fuel dispenser (e.g., those that pump in the range of 5, 10, 15, or 20 gallons per minute) can be used. FIG. 5 illustrates one embodiment of a typical gas station 70. Gas dispensers 75, 76 allow users to pump gas and customers pay either at the pumps or at kiosk 80 (or inside an associated store). The pumps connect to tank 85 via piping 90. Tank 85 holds a large volume of gasoline that is distributed to the individual gas dispensers as needed. Kiosk 80 comprises a meter with a connection to sensors on the tanks to measure the fluid level inside. Thieves can manipulate the gas dispensers via the dispenser pulsar such that a dispenser will pump fuel without a purchase being made. An employee monitoring the meter via computer 95 may not realize a theft has occurred because meter tracks the entire tank, not the individual pumps. Further, the gas being stolen may not appear large compared to the size of tank.
To install the disclosed device on a gas dispenser, at least a portion of the dispenser can be disassembled (thereby providing access to the dispenser pulsar configured within the dispenser interior). As illustrated in FIG. 6, upper doors 100 of a standard fuel dispenser 105 can be unlocked (or removed in some models). The dispenser lower doors 110 and/or side panels 115 can also then removed or opened, revealing the interior components of the dispenser.
In addition, the power source of the gas dispenser can be removed (for safety). The shear valves on each fuel grade in the dispenser can be tripped. The shear valves are installed on fuel supply lines beneath dispensers at grade level to minimize hazards associated with collision or fire at the dispenser. When the shear valves are tripped, poppets are activated that shut off the flow of fuel. The dispenser printer can also be removed if not positioned on the dispenser door. Removal of the printer and power source can give access to the pulsar, allowing for proper placement of device 5.
Typically, pulsar 120 is positioned within the interior of a gas dispenser, held in place within channel 125, as shown in FIG. 7. As noted above, the dispenser fuel pulsar is positioned within the dispenser interior and converts the amount of fuel coming through the pump into a price on the display screen of the dispenser. Specifically, the pulsar rotates and measures how much fuel is being dispensed. Pulsar manipulators can be used to interfere with the pulsar and prevent it from measuring how much fuel is being dispensed. Importantly, when the device pulsar is tampered with, large amounts of gasoline can be obtained for a small percentage of the cost.
During installation, at least one cover is positioned over walls 126 of channel 125 such that each lip 40 rests on the outside of the channel walls, thereby securing the covers in place and preventing unwanted movement. When the covers are properly positioned, first side 60 of block 20 is positioned adjacent or directly adjacent to control panel 130 of pulsar 120, as illustrated in FIG. 8. In some embodiments, when the cover is attached, there should be about 1⁄8 inch of clearance from the top of the pulsers. If both covers have not been installed, while supporting the block, the second cover is then slid into place, completing installation. The arms of each cover can be drilled or otherwise attached to each side of the dispenser frame using standard techniques. In this way, device 5 is secured within the interior of gas dispenser 100, with block 20 covering and protecting the control panel of the dispenser pulsar from manipulation by a thief. In this way, theft of gasoline is prevented from the gas dispenser.
The printer can then be reinstalled, if necessary. The dispenser power source can also be reinserted into the dispenser interior and the shear valves reset. The upper doors can then be closed/reinstalled, along with the side panels and lower doors of the dispenser. Advantageously, the control panel of the dispenser pulsar is inaccessible by thieves while device 5 is installed, thereby preventing the theft of gasoline from the pump.
The presently disclosed device and method offer many advantages over current systems. For example, when device 5 is installed such that block 20 is positioned over and protecting the control panel of the gasoline pump pulsar, the pulsar cannot be manipulated (e.g., to steal gasoline).
The disclosed device can be easily and efficiently installed on existing gasoline pumps by those skilled and familiar with installation systems.
The disclosed device is durable and can remain in position within the interior housing of the gas dispenser for at least several weeks, months, or years.
Device 5 can save significant amounts of money from being lost by gas stations by preventing manipulation of pulsar 120.
The disclosed device cannot be easily removed by thieves because it is bolted or otherwise affixed into place via arms 55 attaching to the interior frame of the gas pump.
Although the present invention and its advantages have been described in detail, various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims. Moreover, the scope of the present application is not intended to be limited to the embodiments of the process, machine, manufacture, composition of matter, means, methods and steps described in the specification.
