First Claim
1. Work platform comprising, in combination:
- a base adapted to be moveably supported upon a floor;
a landing vertically spaced from the base and supported in a cantilever manner above the base, with the landing having a front portion and a rear portion;
a ladder extending from the base to the rear portion of the landing;
a pivotal platform having a first edge and a second edge opposite to the first edge, with the first edge pivotally mounted to the front portion of the landing about a first axis;
a folding platform having a free edge and a rear edge opposite to the free edge, with the folding platform pivotally connected to the second edge of the pivotal platform about a second axis; and
a pivotal interconnection having a first end and a second end opposite to the first end, with the first end pivotally connected to the landing about a third axis parallel to the first and second axes, and with the second end pivotally connected to the folding platform about a fourth axis parallel to the first, second, and third axis, with the folding platform moveable from a storage condition and an operating condition extending from and generally parallel to the landing, with the folding platform extending at a non-parallel angle to the landing in the storage condition.

Abstract
A bi-level work platform includes a landing vertically spaced from and cantilever supported above a U-shaped base. A folding platform is pivotally connected to the landing by a pivotal platform and by gas struts. The folding platform is pivotable between a storage condition within the maximum extent of the landing and the pivotal platform and an operating condition extending from and generally parallel to the landing. The base is movable by rollers at the free ends of legs of the U-shaped base and by retractable casters which are pivotally mounted to the U-shaped base. Removable fall protection is provided on the folding platform including removable flaccid members and is pivotally received between the guide rails of the landing in the storage condition.
