Abstract:
A retrofitted cap locking device, said device being removably couplable to a stem of a tank, the stem being generally hollow and fluidly connected to the tank such that the tank may be filled via the stem, said device covering a removable cap of the stem, said device comprising:a base portion comprising a ring member, said ring member having an annular aperture therein having a diameter substantially equal to a diameter of said stem such that said ring may be removably placed around said stem, said ring member having a peripheral edge; a cover portion comprising a plate, said plate having a top side, a bottom side and a peripheral wall extending therebetween, said bottom side having a flange thereon, said flange comprising a generally annular flange, said flange being spaced from said peripheral wall, said flange having a size adapted to fit around the cap, said plate having a generally circular shape; a first rod being fixedly coupled to said peripheral wall, said first rod being orientated generally perpendicular to a plane of said plate such that said rod extends away from said bottom side of said plate, a free end of said rod being hingedly coupled to said peripheral edge of said base portion; a second rod being fixedly coupled to said peripheral wall, said second rod being orientated generally perpendicular to a plane of said plate such that said second rod extends away from said bottom side of said plate, said second rod being generally positioned on an opposite side of said cover portion with respect to said first rod, said second rod being orientated generally parallel to said first rod; a first annular member being integrally coupled to a free end of said second rod, said first annular member having an axis orientated generally perpendicular to a longitudinal axis of said second rod; a second annular member being integrally coupled to a peripheral edge of said base portion, said second annular member being positioned such that said first and second annular members are generally adjacent and coaxial when said second rod is orientated generally perpendicular to a plane of said base portion; a locking means for selectively locking the first and second annular members together; wherein said annular flange is located substantially equidistant between said peripheral wall and said inner wall; wherein said base portion is placed over the stem and the cap is placed on the step, wherein said cover portion is placed over the cap such that said cap is within said flange; and wherein said locking means is selectively insertable through said first and second annular members to resist movement between said base and cover portions.
