The underground fuel tank indicator flag 100 (hereinafter invention) comprises a stanchion 200 and a flag 250. The invention 100 may mark the location of a filler port where a tanker truck would couple to an underground fuel tank to add fuel to the underground fuel tank. The invention 100 may be resilient such that a vehicle could drive over the stanchion 200, moving the stanchion 200 to a horizontal orientation, and the stanchion 200 will restore itself to an upright position. The invention 100 may convey an attribute of the fuel in the underground fuel tank. As non-limiting examples, the attribute may indicate the fuel type, an octane rating, or a fuel blend.

The stanchion 200 may comprise a lower stanchion portion 210, an upper stanchion portion 215, a flange 205, a wire 220, and a washer 225. The bottom of the stanchion 200 may be attached to a base 980. As non-limiting examples, the base 980 may be a cap for the filler port, another part of the underground fuel tank, a removable cover over the filler port, of the ground adjacent to the filler port, including the tarmac adjacent to the filler port. The stanchion 200 may hold the flag 250 above the ground.

The lower stanchion portion 210 may be a subdivision of the stanchion 200 located between the flange 205 and the upper stanchion portion 215. The lower stanchion portion 210 may be a cylindrical shape and may be oriented along a vertically-oriented central axis 290. The lower stanchion portion 210 may have a narrower diameter than the flange 205 and a larger diameter than the upper stanchion portion 215. The lower stanchion portion 210 may increase the stability of the stanchion 200.

The upper stanchion portion 215 may be a subdivision of the stanchion 200 located above the lower stanchion portion 210. The upper stanchion portion 215 provides elevation for the flag 250. The upper stanchion portion 215 may be a cylindrical shape aligned along the vertically-oriented central axis 290. The vertically-oriented central axis 290 passing through the upper stanchion portion 215 and the vertically-oriented central axis 290 passing through the lower stanchion portion 210 may be the same. The stanchion 200 may be made of a resilient material.

In some embodiments, the lower stanchion portion 210 may be 3+/−1 inches tall with a diameter of ¾+/−⅛ inch, the flange 205 may have a diameter of 1+/−⅛ inch, the upper stanchion portion 215 may have a diameter of ¼+/−⅛ inch, and a length of 7+/−1 inches.

The flange 205 is a widening at the bottom of the stanchion 200 that increases stability of the stanchion 200. The flange 205 may increase the surface area available to attach the stanchion 200 to the base 980.

The wire 220 may assist in returning the stanchion 200 to an upright position if the stanchion 200 is pushed towards horizontal. The wire 220 may be oriented centrally within the stanchion 200 and may be oriented vertically. The top of the wire 220 may be coupled to the top of the stanchion 200. The bottom of the wire 220 may be coupled to the bottom of the stanchion 200.

The washer 225 may stiffen the bottom of the stanchion 200. The washer 225 may be an annular metal disk that is horizontally oriented. The washer 225 may be located above and adjacent to the flange 205.

The flag 250 may be a color-coded indicator adapted to inform a driver of the tanker truck regarding the fuel stored in the underground fuel tank. One edge of the flag 250 may be coupled to the upper stanchion portion 215. The flag 250 may be rectangular in shape and may be made from a resilient material. As a non-limiting example, the color of the flag 250 may indicate the fuel type stored in the underground fuel tank.

In some embodiments, the flag 250 may be 3½+/−½ inch high by 3½+/−½ inch wide.

In some embodiments, the flag 250 may comprise a plurality of colors that convey a plurality of attributes of the fuel. The specific colors, the number of color regions, the shape of color regions, placement of color regions, or combinations thereof may convey the plurality of attributes of the fuel. As a non-limiting example, a diamond-shaped region of a first color section 272 may convey the fuel type and a background of a second color section 274 may convey the octane rating.

In some embodiments, the invention 100 may comprise a plurality of flags. Each of the plurality of flags may be coupled to the upper stanchion portion 215. Each of the plurality of flags may convey a specific attribute. As a non-limiting example, a first flag 252 may be located at the top of the stanchion 200 and may convey a first attribute and a second flag 254 located beneath the first flag 252 may convey a second attribute.

In use, the invention 100 is coupled to the base 980 adjacent to the filler port of the underground fuel tank. As a non-limiting example, the invention 100 may be coupled to the base 980 using an adhesive. The flag 250 or the plurality of flags are selected such that the specific colors, the number of color regions, the shape of color regions, the placement of color regions, or combinations thereof convey the plurality of attributes regarding the fuel that is to be stored in the underground fuel tank. As the driver approaches the filler port with the tanker truck, the driver can verify that the filler port is correct for the delivery that the tanker truck is making. If the invention 100 is run over, the vehicle that ran over it may force the stanchion 200 into a horizontal orientation. When the vehicle has driven off the invention 100, the stanchion 200 may restore itself to a vertical orientation where the flag 250 or the flags 250 are visible.

Definitions

Unless otherwise stated, the words “up”, “down”, “top”, “bottom”, “upper”, and “lower” should be interpreted within a gravitational framework. “Down” is the direction that gravity would pull an object. “Up” is the opposite of “down”. “Bottom” is the part of an object that is down farther than any other part of the object. “Top” is the part of an object that is up farther than any other part of the object. “Upper” refers to top and “lower” refers to the bottom.
