Fuel pump nozzle lever holding device
A fuel pump nozzle lever holding device is claimed that allows a user to pump fuel without applying constant hand pressure to the fuel pump nozzle lever. The device works by either clamping or wedging the nozzle lever in the compressed or “open” position. Embodiments of the invention include a clamp that closes and latches to compress the nozzle lever to the nozzle handle; a spring tension clamp that clamps over the nozzle lever and handle; and a bracing bar that wedges the nozzle lever closed from inside of the nozzle handle.
This application claims priority to Provisional Patent Application U.S. Ser. No. 60/655,207, entitled “Fuel Pump Nozzle Lever Holding Device” and filed on Feb. 22, 2005, which is fully incorporated herein by reference.
BACKGROUND1. Field of the Invention
The present invention relates generally to an aid for dispensing gasoline or other fuels from a fuel pump nozzle, and in particular to a fuel pump nozzle lever holding device.
2. Background of the Invention
In order to dispense gasoline or other fuels through a fuel nozzle into a tank or fuel container, the nozzle's trigger-like lever must be continually squeezed with some level of force. Many self-serve gasoline stations include attachments on the nozzle that allow the user to “latch” the lever into the “open” position, thus allowing the user to release the nozzle while still dispensing fuel. This type of latching device generally consists of a hinged plate that acts as a holder for the trigger-like valve operating lever. The hinged plate is attached at one end to the operating lever in such a manner that the other end of the plate moves over a notched member provided on the inside bottom of the trigger guard of the valving device as the operating lever is squeezed open. In operation, a user squeezes the lever to achieve the desired flow of gasoline, and then pushes the lower end of the holder into a seat in a notch, causing the operating lever to remain in the “open” position.
Some gasoline stations, however, do not provide the convenience of the latching mechanism described above, and at other stations the latching mechanisms are broken or have been disabled. Without these latching mechanisms, a user must apply continual force to the nozzle lever for the time it takes to dispense the gasoline, which can be several minutes. While this may be a mere annoyance to some, to individuals with limited hand strength or injuries, it could be a true hardship. The present invention solves this problem by providing a device which can be easily and temporarily installed by anyone to keep the nozzle lever squeezed into the open position without continuous pressure by the user.

The present invention improves upon the prior art and achieves, in a simple and economical device, the desired function of holding the trigger-like lever on the fuel nozzle open, freeing the operator to perform other tasks consisting with remaining safe with respect to the fueling operation that is underway.
SUMMARY OF THE INVENTIONTherefore, the primary objective of this invention is to provide a fuel pump lever holding device that is attached easily to an automatic gas pump nozzle by an operator to hold the trigger of the nozzle in a desired manually adjusted position to dispense fuel at a desired rate of fluid flow and allow for hands-free pumping of fuel. Another object of the invention is to provide this function in a compact design that may be stored in a vehicle's gas compartment door. Another object of the invention is to provide these functions in a simple design that is reasonably inexpensive to manufacture.
These and other objects are attained by the present invention, which proposes several embodiments to achieve these objectives. One embodiment is a clamp-like device that releaseably compresses the fuel nozzle handle and lever (while the lever is squeezed or depressed) and latches to hold the lever in the squeezed position. Another embodiment is a spring-loaded clamp that clips over the handle and depressed lever and is held in place by the tension in the spring. Still another embodiment is a brace-type device that is releaseably installed between the fuel nozzle handle lever and the inner surface of the fuel nozzle handle opposite of the lever and depresses the lever by applying a force between the inner surface of the nozzle handle and the lever.
For purposes of summarizing the invention, certain aspects, advantages, and novel features of the invention have been described herein. It is to be understood that not necessarily all such advantages may be achieved in accordance with any one particular embodiment of the invention. Thus, the invention may be embodied or carried out in a manner that achieves or optimizes one advantage or group of advantages as taught herein without necessarily achieving other advantages as may be taught or suggested herein.
These and other embodiments of the present invention will also become readily apparent to those skilled in the art from the following detailed description of the embodiments having reference to the attached figures, the invention not being limited to any particular embodiment(s) disclosed.
BRIEF DESCRIPTION OF THE DRAWINGSThe present invention is described with reference to the accompanying drawings. In the drawings, like reference numbers indicate identical or functionally similar elements.
The present invention and its advantages are best understood by referring to the drawings. The elements of the drawings are not necessarily to scale, emphasis instead being placed upon clearly illustrating the principles of the invention.
In operation, the device is clamped over the fuel nozzle lever and handle (not illustrated) and tightened. To release the device from the fuel nozzle lever, latch 6 on the female strap 2 is moved. In one embodiment, the required movement of the latch for unlatching is movement in the direction opposite of the latching direction, though other embodiments of latches could also be employed.
The clamp may be fabricated from any number of materials, including, but not limited to, plastic and composite-type materials.
