FUNNEL SYSTEM FOR A GAS TANK

Abstract

A funnel system for a gas tank that can be stored within the gas tank during operation of a machine such as a lawnmower or snow blower. Upon removing the cap of the gas tank in a first embodiment, a funnel is moved toward an open position as the funnel is biased toward the open position. Once fuel is added to the gas tank, a guide member of the cap is utilized to force the funnel toward the closed position and then secured to the gas tank. A second embodiment utilizes a separate guide member, separate from the cap to move the funnel to and from the open position to the closed position.

DETAILED DESCRIPTION OF THE INVENTION

[0015] Now referring to the figures, a funnel system 10 for a gas tank 20 is described. In a first embodiment of the funnel system 20, FIGS. 1-5 show the funnel system 10 comprising a funnel 40 that is at least partially held within the gas tank 20 and selectively stored within the gas tank 20 when the funnel 10 is not in use. The funnel system 10 has a first position when a cap 30 is secured to the gas tank 20. The first position of the funnel system 10 represents a closed position for the funnel 40.

[0016] Upon removal of the cap 30, the funnel 40 moves from the first position to a second position. The second position of the funnel 40 and funnel system 10 represents an open position. Preferably the funnel 40 is biased toward the open position. Accordingly, once the cap 30 is removed the funnel 40 automatically extends toward the second position.

[0017] The funnel 40 has a plurality of flaps 46. The flaps 46 are attached to a base member 44. Once in the open position, fuel 50 can be added and the funnel 40 directs 11 the fuel 50 into the interior of the gas tank 20.

[0018] As best seen in FIG. 2, the cap 30 preferably has a guide member 32 extending from a main body 34 of the cap 30. The guide member 32 has a first end 36 and a second end 38. The second end 38 can push the base member 44 of the funnel 40 toward the closed position. As the funnel 40 is attached to the base member 44, the plurality of flaps 26 overlap more and the funnel 40 returns to the closed position within the gas tank 20.

[0019] In FIGS. 6-8, a second embodiment of a funnel system 110 for a gas tank is shown. The second embodiment is the preferred embodiment. The funnel system 110 includes a funnel 140, a guide member 132 and a frame 150. The funnel 140 is preferably made of a flexible material so the funnel 140 can be moved from a first position to a second position. The first position corresponds to a closed position, while the second position corresponds to an open position.

[0020] FIG. 6 shows the funnel system 110 and the funnel 140 in an open position. The funnel 140 extends out of the gas tank. A user can then pour gasoline or some other liquid into the gas tank. As best shown in FIG. 7, the guide member 132 has a first end 133 and a second end 134. The second end 134 of the guide member 132 comprises a base 136. The base 136 has openings 137 such that gasoline can enter the gas tank.

[0021] As best shown in FIG. 6, the frame 150 has connecting members 151 that connect a top 152 of the frame 150 to a bottom 153 of the frame 150. The guide member 132 is movable within the frame 150. The base 136 of the guide member 132 can be moved from the bottom 153 of the frame 150 towards the top 152 of the frame 150. The funnel 140 is housed at least partially within the frame 150 and the gas tank when the funnel system 110 and the funnel 140 are in the first position or closed position. The funnel 140 is at least partially outside of the frame 150 and the gas tank when the funnel system 110 and the funnel 140 are in the second position or open position. A user of the funnel system 110 can utilize a force to push or pull the guide member 132. When the funnel system 110 is in the closed position, the user pulls up on the guide member 132 to place the funnel system 110 and funnel 140 into the open position. When the funnel system 110 is in the open position, the user pushes the guide member 132 downward toward the bottom 153 of the frame 150. The funnel 140 folds down and is then stored within the frame 150 and the gas tank.

[0022] As best shown in FIGS. 6 and 8, the frame 150 includes features to enhance the functionality of the funnel system 110 and to assist in maintaining certain positions of the frame 150 and guide member 132. The frame 150 has a lip 164 that prevents the frame 150 and the funnel system 110 from falling down into the gas tank. Additionally, the frame 150 includes a plurality of securing members 165. The plurality of securing members 165 are flexible and include a hook 166. The hook 166 prevents the frame 150 from being lifted out of the gas tank. The frame 150 also has a first retaining member 160 and a second retaining member 162. The first retaining member 160 prevents the guide member 132 from being pulled outside of the gas tank. Specifically, the first retaining member 160 interacts with the base 136 of the guide member 132. The second retaining member 162 allows the base 136 of the guide member 132 to maintain the funnel system 110 in the open position. The user must utilize a certain downward force to overcome the friction between the base 136 and the second retaining member 162 to return the funnel 140 and funnel system 110 to the closed position.

[0023] Having thus described the invention in connection with the several embodiments thereof, it will be evident to those skilled in the art that various revisions can be made to the several embodiments described herein without departing from the spirit and scope of the invention. It is my intention, however, that all such revisions and modifications that are evident to those skilled in the art will be included with in the scope of the following claims. Any elements of any embodiments disclosed herein can be used in combination with any elements of other embodiments disclosed herein in any manner to create different embodiments.
