Patent Application
20140069550
The present invention relates to devices and methods for pumping fuel in a vehicle fuel tank without holding a handle of a fuel supplying hose.
Devices and methods of the above mentioned type are known in the art in the gas supply industry. In the gas supply industry a handle of a fuel supplying hose is provided with a lever which, when pulled up by a user, opens the flow of fuel from the fuel supplying hose and the fuel outlet nozzle insertable into an opening of a fuel tank of a vehicle. In order to release a user's hand from the task of holding the pulled up handle, a tumable piece is turned and presses against the pulled up lever to hold it in its upright position. However, in many instances the tumable piece is not reliable retained in its turned position and thereby is unable to securely maintain the lever in its upright position, resulting in the lever returning to its lower position and interrupting the flow of fuel through the fuel supplying pipe to the fuel outlet nozzle and into the fuel tank. It is therefore believed that it is advisable to develop a device and a method of this type, which can provide a reliable, uninterrupted pumping of vehicle fuel into a fuel tank.
Accordingly, it is the purpose of the present invention to provide a device and a method for pumping fuel in a vehicle fuel tank without holding the handle of a fuel supplying hose which is a further improvement on existing devices and methods of this type.
In furtherance of the improvement of existing devices of this type, specifically for pumping fuel in the fuel tank, the device which is the subject of this patent application has an element insertable into a handle of a fuel supplying hose and is configured to be located between an activated lever and a wall of the handle so as to retain the lever in an activated position. The element in question is freely insertable into the space between the lever and the wall of the handle and is freely completely removable by a user from the space between the lever and the wall of the handle.
In accordance with another feature of the present invention, the body of the element has a roughened surface cooperatable with a member selected from the group consisting of the lever of the handle, the wall of the handle, and both, so as to secure the position of the body of the element inside the space and to prevent an accidental slippage of the element from the space between the lever and the wall of the handle during pumping of the vehicle fuel.
In accordance with still a further feature of the present invention, the device is provided with means for connecting the element to a vehicle ignition key, so that the element is connected to the vehicle ignition key at all times permitting the element to be inserted into the space between the lever and the wall of the handle only when the ignition key turns off vehicle ignition and is removed from a vehicle ignition key hole. Therefore the pumping of the vehicle fuel can be carried out only when a vehicle engine is turned off.
In accordance with still a further feature of the present invention, a method of allowing pumping of a vehicle fuel into a vehicle fuel tank is proposed, which includes the steps of introducing a fuel supplying hose into a fuel tank inlet, activating a lever of a handle of the fuel supplying hose, and inserting between the activated lever and a wall of the handle an element to be located between the activated lever and the wall of the handle so as to retain the lever in an activated position, including freely inserting of a body of the element by a user into a space between the lever and the wall of the handle and freely completely removing the body of the element from the space between the lever and the wall of the handle after finishing a process of pumping the vehicle fuel into the vehicle tank.
When the above mentioned device is designed in accordance with the present invention and the method is performed in accordance with the present invention, the lever of the handle of the fuel supplying hose is reliable held in its activated, upright position, the user's hands are free, and the process of pumping a fuel into a vehicle tank is carried out uninterruptedly for the necessary period of time.
The novel features of the present invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and method of operation, will be best understood from the following description of the preferred embodiments, which is accompanied by the following drawings.
A device for pumping fuel into a vehicle fuel tank in accordance with the present invention is identified as a whole with reference numeral 1. The device 1 is used during pumping of the fuel, when an outlet pipe 2 provided on a handle 3 of a fuel supplying hose 4 is introduced into an opening of a not shown fuel tank of a vehicle.
As well known in the gas supply industry, the opposite end of the fuel supplying hose operates in conjunction with a not shown fuel storage, as for example in a fuel supply station. When a lever 5 provided in the handle 3 is activated, as for example when lifted to its upright position, the fuel communication is established, and the fuel flows freely into the vehicle tank.
The inventive device includes an element 6 freely insertable into the handle 3 by a user and freely removable from the handle 3 by the user. In other word, the element 3 has no fixed and/or permanent connections to the handle.
As shown in particular in
After filling the fuel tank of the vehicle, the user completely removes the element 6 from the space between the lever 5 and the wall 7 of the handle, and the lever 5, in a known manner, moves back, for example under the action of a spring, to its original non-activated position. The process of supplying fuel into a vehicle fuel tank thereby stops.
As shown for example in
The roughening formations 10 provide an increased friction between the body of the element 6 on the one hand, and the lever 5 of the handle, or the wall 7 of the handle, or both the lever 5 and the wall 7 of the handle 3 on the other hand. It thereby increases reliability of retention of the element 6 inside the space between the lever 5 and the wall 7 of the handle 3, when the element 6 is inserted into the space, and the element 6 can not accidentally slide out of the handle.
In accordance with another feature of the present invention, the element 6 can be provided with means for connection to an ignition key of the vehicle as shown in
It is well known that it is strongly recommended to turn off the vehicle engine before pumping a fuel into a fuel tank. This requirement is forcefully enforced when the above mentioned feature is provided in the present invention. In order to introduce the element 6 of the inventive device into the handle 3 and pump the fuel, it is absolutely necessary to remove the ignition key 13 from the ignition key hole resulting in the shutting down of the vehicle engine. Only thereafter can the element 6 can be inserted into the handle 3 and operate as described hereinabove.
The invention is not limited to the details shown since various modifications and structural changes are possible without departing from the spirit of the invention.
