Chair with adjustable foot rest

An adjustable chair comprising

• a bollard, a chair structure, and a foot rest structure;
• wherein the bollard and the foot rest structure attach to the chair structure;
• wherein the foot rest structure moves towards and away from the chair;
• wherein the position of the foot rest structure is controlled using a hand lever;
• wherein the bollard is an extension structure that raises the chair structure above a supporting surface;
• wherein the foot rest structure comprises a foot plate, a plurality of worm drives, an inferior end plate, and a superior end plate;
• wherein the foot plate is further defined with a first medial edge and a second medial edge;
• wherein the bollard comprises a pedestal, a stanchion, and a mounting plate;
• wherein the pedestal and the mounting plate attach to the stanchion;
• wherein the pedestal rests upon a supporting surface;
• wherein the pedestal forms the last link of the load path between the chair structure and the supporting surface;
• wherein the pedestal is a disk-shaped object;
• wherein the stanchion is an extension structure;
• wherein the stanchion separates the mounting plate from the pedestal;
• wherein the stanchion is further defined with an inferior stanchion end and a superior stanchion end;
• wherein the mounting plate is a plate structure;
• wherein the mounting plate attaches the chair structure to the bollard;
• wherein the chair structure comprises a bench structure, a back support structure, and a leg cushion;
• wherein the back support structure and the leg cushion attach to the bench structure;
• wherein the leg cushion is further defined with a third medial edge and a fourth medial edge;
• wherein the bench structure is further defined with a fifth medial edge and a sixth medial edge;
• wherein the back support structure is further defined with a seventh medial edge and an eighth medial edge;
• wherein the foot rest structure is an adjustable structure;
• wherein the elevation of the foot rest structure adjusts relative to the chair structure;
• wherein the bench structure is a horizontal surface;
• wherein the bench structure mounts on the bollard;
• wherein the bench structure is a hollow rectangular block structure;
• wherein the back support structure is a rectilinear block structure;
• wherein the back support structure attaches to the bench structure telescopically;
• wherein the back support structure forms a cant relative to the bench structure;
• wherein the position of the back support structure relative to the bench structure is adjustable;
• wherein the leg cushion is a rectilinear block structure;
• wherein the leg cushion attaches to the bench structure;
• wherein the leg cushion forms a cant relative to the bench structure;
• wherein the bench structure further comprises a bracket;
• wherein the bracket is a mechanical structure that attaches the bench structure to the mounting plate;
• wherein the bench structure further comprises a telescopic cavity;
• wherein the telescopic cavity is a cavity formed in the bench structure of the chair structure;
• wherein the telescopic cavity is a negative space formed in the shape of a hollow first prism that is further defined with an inner dimension;
• wherein access into the telescopic cavity is through the sixth medial edge of the bench structure.
