Large sealing lid with slides and lock

In an agricultural machine having a supply tank with a tank opening, a closure assembly comprising:

• a tank opening flange configured to at least partially surround the tank opening;
• a tank lid operable between an open position and a closed position, the tank lid while in the closed position is configured to cover the tank opening, the tank lid while in the open position is configured to uncover the tank opening, the tank lid having a first lid flange opposite a second lid flange;
• a handle operably coupled to the tank lid, the handle configured to be maneuvered to move the tank lid between the open and closed positions;
• a plurality of mechanisms coupled to the tank lid;
• and
• a pair of guides coupled to opposite sides of the tank opening flange, each of the pair of guides defining a guide opening for receiving at least one of the plurality of mechanisms, wherein the guide opening is defined in each of the pair of guides between a first end and a second end, the guide opening includes an arcuate portion that extends from the first end to a climax portion located between the first and second ends wherein the arcuate portion has a length that corresponds to raising the tank lid to a maximum raised position when the tank lid is between the open and closed positions;
• wherein, in the closed position, the handle is in an upright position and the tank lid is sealingly coupled to the tank opening flange;
• wherein, during movement from the closed position to the open position, the handle is moved from an upright position to raise the tank lid from the tank opening flange, release a sealed connection between the tank lid and the tank opening, move the tank lid along a curved path as at least one of the plurality of mechanisms slides along the arcuate portion of the guide opening of the pair of guides, and move the tank lid downwardly relative to a side of the supply tank and uncover the tank opening as the at least one of the plurality of mechanisms slides along the climax portion to the second end of the guide opening of the pair of guides;
• wherein, in the open position, the tank lid is located below a top edge of the tank opening flange and the handle is folded in a downward position to at least partially overlap the tank lid.

In an agricultural machine having a supply tank with a tank opening, a closure assembly comprising:

• a tank opening flange configured to at least partially surround the tank opening;
• a tank lid operable between an open position and a closed position, the tank lid comprising a first lid flange opposite a second lid flange;
• a handle operably coupled to the tank lid, the handle configured to be controlled to move the tank lid between the open and closed positions;
• a seal coupled to the first lid flange and the second lid flange, where in the closed position the seal is configured to be compressed between the first lid flange, the second lid flange, and the tank opening flange to form a sealed connection between the tank lid and the tank opening;
• a plurality of mechanisms coupled to the tank lid;
• and
• a pair of guides coupled to opposite sides of the tank opening flange, each of the pair of guides defining a guide opening for receiving at least one of the plurality of mechanisms, wherein the guide opening is defined in each of the pair of guides between a first end and a second end, the guide opening comprising an intermediate location between the first end and the second end;
• wherein, in the open position, the handle is in a folded position such that the handle at least partially overlaps the tank lid;
• wherein, during movement from the open position to the closed position, the handle is moved from the folded position to controllably move the tank lid upwardly relative to a side of the supply tank as the plurality of mechanisms slide along a first portion of the pair of guides, move the tank lid along a curved path as the plurality of mechanisms slide along a second portion of the pair of guides such that the seal is positioned above the tank opening flange, contact the seal with the tank opening flange, and lower the tank lid to compress the seal between the tank opening flange, the first lid flange, and the second lid flange;
• wherein, as the plurality of mechanisms slide along the first portion of the pair of guides from the second end to the intermediate location, the tank lid moves upwardly relative to the side of the supply tank;
• wherein, as the plurality of mechanisms slide along the second portion of the pair of guides from the intermediate location to the first end, the tank lid moves along an arcuate path until the seal is compressed between the first lid flange, the second lid flange, and the tank opening flange.
