Integrally molded stackable commode chair

An unitary stackable commode chair comprising:

• a. a generally horizontal seat with a top surface, an underside, a front, a first and a second lateral side, and a rear terminating in a substantially vertical backrest extending upward, the seat having a central opening;
• b. two front legs extending downward from the front of the seat, the legs being shaped substantially as angles open on the sides and toward the front and comprising a flat flange and a curved flange, the flat flange lying in substantially the same plane as the lateral side of the seat, and the curved flange lying at a substantially right angle to the flat flanges;
• c. two rear legs extending downward from the rear of the seat, the legs being shaped substantially as angles open on the sides and toward the front and comprising a flat flange and a curved flange, the flat flange lying in a plane substantially parallel to the plane of the lateral side of the seat, and the curved flange lying at a substantially right angle to the flat flanges;
• d. armrests integrally formed with the seat and front legs at one end and the backrest at the other end, the armrests joining each of the two front legs to the backrest;
• e. a plurality of subjacent ribs and gussets comprising
• i. at least one front rib adjacent and substantially parallel to the front of the seat and joining the two front legs, the front rib being intersected by at least one gusset,
• ii. at least two first lateral ribs adjacent to and substantially parallel to the first lateral side and extending from the front of the seat to the rear leg, the lateral ribs being intersected by at least one gusset,
• iii. at least two second lateral ribs adjacent to and substantially parallel to the second lateral side and extending from the front of the seat to the rear leg, the lateral ribs being intersected by at least one gusset,
• iv. at least one rear rib adjacent and substantially parallel to the rear of the seat and joining the two rear legs;
• and,
• f. the seat further having a slightly resilient transition zone partially bordering the central opening and being free from subjacent ribs and gussets, with the seat being able to withstand an impact force of 225 pounds at a height from about 5 to about 16 inches;
• and,
• g. at least one stacking rib extending downward from the underside of the seat and being coextensive with one of the front and rear legs.

• d. armrests integrally formed with the seat and front legs at one end and the backrest at the other end, the armrests joining each of the two front legs to the backrest;
• e. a plurality of subjacent ribs and gussets comprising:
• i. three front ribs adjacent and substantially parallel to the front of the seat, with two ribs joining the flat flanges of the two front legs and the third rib extending from the first lateral side to the second lateral side, the front ribs being intersected by six substantially equally spaced gussets, the gussets extending from the front of the seat toward the rear,
• ii. two lateral ribs adjacent and substantially parallel to the first lateral side and extending from the front of the seat to the curved flange of the rear leg, the lateral ribs being intersected by three substantially equally spaced gussets, the gussets extending from the first lateral side toward the central opening,
• iii. two lateral ribs adjacent and substantially parallel to the second lateral side and extending from the front of the seat to the curved flange of the rear leg, the lateral ribs being intersected by three substantially equally spaced gussets, the gussets extending from the second lateral side toward the central opening,
• iv. two rear ribs adjacent and substantially parallel to the rear of the seat and joining the flat flanges of the rear legs, the rear ribs being joined by two spaced apart gussets;
• and,
• f. the seat further having a slightly resilient transition zone partially bordering the central opening and being free from subjacent ribs add gussets, with the seat being able to withstand an impact force of 225 pounds at a height of from about 5 to about 16 inches;
• and,
• g. at least one stacking rib extending downward from the underside of the seat and being coextensive with one of the front and rear legs.
