Patent Application
20240092626
The present invention relates to fuel nozzles and, more particularly, a device configured to keep the fuel nozzle in the activated position for hands-free pumping of fuel.
A gasoline pump or fuel dispenser is a machine at a filling station that is used to pump gasoline (petrol), diesel, or other types of liquid fuel into vehicles. Fuel nozzles are attached to the pump with flexible hoses, so they can reach the vehicle's filler inlet. Fuel nozzles commonly offer a handle trigger to activate the pumping of the fuel. The fuel nozzle also enables hands-free pumping via a locking mechanism (that pivotably extends from the handle trigger) that holds the handle trigger in the activated position (by selectively wedging in a groove of a series grooves) until it is sensed that the tank is sufficiently full, whereby a sensing mechanism automatically moves the trigger to a deactivated position. Which is convenient in cold weather, when the user of the fuel nozzle wants to use their hands for something else, like operating their smart phone, or when the user desires to avoid the smell of gasoline or otherwise does not want to be anywhere near the pump when it is in operation.
However, there are times with the locking mechanism is not provided or may be broken, forcing the driver to use their hands, and thereby requiring them to stand in the cold, unable to use both hands for something else, and/or endure the smell of gasoline.
As can be seen, there is a need for a device configured to keep the fuel nozzle in the activated position for hands-free pumping of fuel, wherein the device is separable from the gasoline pump.
The present invention, colloquially known as the “gas bracelet”, engages the fuel nozzle trigger mechanism in the activated position, allowing the user to pump gas hands-free.
In one aspect of the present invention, a device for maintaining a fuel nozzle in an activated position includes a clamp assembly having a first jaw portion and an opposing second jaw portion pivotably associated to each other by way of a pivot point so that the jaw portions move between an open position and a closed position, wherein said jaw portions are biased in the closed position so as to maintain a trigger mechanism of the fuel nozzle in the activated position.
In another aspect of the present invention, the above-mentioned device further includes at least one of the following: wherein the trigger mechanism of the fuel nozzle is urged against a handle of the fuel nozzle; wherein the pivot point is a spring-loaded hinge, wherein the pivot point is an arced crossbar, wherein the first jaw portion provides a plurality of teeth along both longitudinal edges thereof, wherein along each longitudinal edge, a length of each tooth is a function of its proximity to a midline of the first jaw portion, wherein the jaw portions each provide a plurality of teeth pairs in a spaced apart arrangement.
In yet another aspect of the present invention, a method of maintaining a fuel nozzle in an activated position, the method includes clamping a trigger mechanism of the fuel nozzle toward a handle of the fuel nozzle so that the fuel nozzle is in the activated position for a desired period, by way of the above-mentioned device.
In another aspect of the present invention, a device for maintaining a fuel nozzle in an activated position includes: a clamp assembly having a first jaw portion and an opposing second jaw portion pivotably associated to each other by way of a pivot point so that the jaw portions move between an open position and a closed position, wherein said jaw portions are biased in the closed position so as to maintain a trigger mechanism of the fuel nozzle in the activated position, wherein the trigger mechanism of the fuel nozzle is urged toward a handle of the fuel nozzle by way of teeth in the closed position, wherein the pivot point is an arced crossbar, wherein the jaw portions each provide a plurality of teeth pairs in a spaced apart arrangement, whereby a method of maintaining a fuel nozzle in an activated position is enabled by clamping a trigger mechanism of the fuel nozzle so that the trigger mechanism is in the activated position for a desired period, by way of the above-mentioned device, wherein two interfacing teeth of the clamp assembly prevent the trigger mechanism from moving away from the activated position, and wherein the arced crossbar engages a rear portion of the fuel nozzle.
In another aspect of the present invention, the device for maintaining a fuel nozzle in an activated position includes the following: a clip assembly having a first jaw portion and an opposing second jaw portion pivotably associated to each other by way of a pivot point so that the jaw portions move between an open position and a closed position, wherein the first jaw portion provides a plurality of spaced apart teeth that mimic grooves for a locking mechanism of the fuel nozzle to engage when the clip assembly is in the open position, whereby a method of maintaining a fuel nozzle in an activated position is enabled by nesting the above-mentioned clip assembly within a trigger guard of the fuel nozzle so that the plurality of teeth are facing upward from a lower portion of the trigger guard; and engaging the locking mechanism between two adjacent teeth of the plurality of teeth.
These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description and claims.
The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.
Broadly, an embodiment of the present invention provides a device separable from a gasoline pump, wherein the device is configured to engage the trigger mechanism of the gasoline pump's fuel nozzle to hold the fuel nozzle in the activated position, thereby enabling hands-free pumping from the fuel nozzle. The device has a set of jaws biased in a closed position yet movable to an open position through manipulation of its lever arms. Teeth provided with the set of jaws facilitate the maintaining of the fuel nozzle in the activated position.
Referring now to
The first jaw portion 12 may have a series of teeth 14 that depend from both longitudinal edges thereof. The teeth 14 extend in the direction of the second jaw portion 18 in the closed position. The proximal end of the first jaw portion 14 has a grip element 16 that extends beyond the distal end of the second jaw portion 18 in the closed position. The grip element 16 may provide an arcuate edge from which a flange element projects so as to define a semicircular cavity.
In the open position, the second jaw portion 18 may pivot/rotate more that ninety degrees about the pivot point 20.
In use, referring to

Regarding use of the clamp assembly 22, referring to
Alternatively, clamp assembly 22 provides sufficient bias (by way of the spring-loaded hinge or arced crossbar) in the closed position that the trigger mechanism 32 of a nozzle 30 is urged to maintain an activated position (e.g. opening the valve that allows fuel to flow from the nozzle 30) without further manipulation by a user, that the nozzle 30 is thereby operating “hands-fee” when either the grip element 16 or teeth 14 and the second jaw portion 18 are urging the trigger mechanism 32 (against the handled of the nozzle 30) in the activated position or when the force provided between the occlusal portions of two opposing teeth 26 are clamping the trigger mechanism 32 in the activated position.
Referring now to the Figures of the provisional patent application, which is incorporated herein by reference, the present invention may include a clip assembly. The clip assembly may have a first jaw portion and an opposing second jaw portion pivotably associated to each other by way of a pivot point in a scissor-like configuration, whereby the two jaw portions and move between an open position and a closed position wherein the two jaw portions engage each other or an object in between. The clip assembly is biased in the closed position.
The bias of the closed position can be overcome by urging a clip arm of the clip assembly in a first direction, since the clip arm is operatively associated with the pivot point though on an opposing side thereof relative to the first jaw portion. Thus, like a lever about the pivot point fulcrum, urging the clip arm in the first direction results in the first jaw portion moving away from the second jaw portion. The pivot point may be a spring-loaded hinge or swinging bar.
The first jaw portion may have a series of teeth that depend from both longitudinal edges thereof. The teeth may extend in the direction of the second jaw portion, though the teeth end prior to touching the second jaw portion in some embodiments. In one embodiment, the length of the tooth depends on its location along the first jaw portion, wherein the distal teeth extend a fraction of the length of the mesial teeth. The proximal end of the first jaw portion has a grip element having a length greater than any of the teeth, and so a distal end of the grip element engages the second jaw portion in the closed position.
