    Abstract: A work platform configured to be adjustable in both height and width, while enabling ease in transformation between an open, use configuration in a closed, storage configuration. The work platform having a platform and a pair of leg frames pivotably coupled to opposite ends of the platform, each of the pair of leg frames including a first leg and a second leg, each of which includes a first member pivotably coupled to the platform, and a second member shiftable relative to the first member, an intermediate rung operably coupled to respective distal ends of the first members and including a length extension lock mechanism configured to inhibit shifting of the second members relative to the first members, and a base rung member including a crossmember operably coupled to the respective distal ends of the second members.

    Abstract: A step stool or ladder includes a latch that engages a cross member to prevent a step from disengaging from the cross member. The curved end of the latch has a tail that provides additional weight to the end of the latch that engages the cross member and allows for decreased tolerances in manufacturing the latch. The other end of the latch has a knob that extends through an opening in the step so that the latch is accessible and to give visual cues to the user. The knob also maintains the latch in its position in the opening in the step. A bent out portion of the latch midsection serves to limit the amount of travel between the knob and the bent portion. The latch rotates on the portion of the latch between the bent portion and travel limiter and the knob attached to the latch.

    IPC: A47C12/00

    CPC classification number: A47C12/00

    Abstract: A folding stool has trapezoidal sides including front and rear nonfolding side walls and left and right folding end walls. Each end wall includes first and second nonfolding half-walls and a hinge connecting these half-walls to each other. The folding stool includes a nonfolding top wall connected to the top of the front side wall by a hinge and a strut connected proximate the middle of the top wall at one end and proximate the top of the rear side wall at the other end. The top wall extends horizontally outwardly from the left and right end walls and rear side wall when the folding stool is in its unfolded position to rest upon the left and right end walls and rear side wall to support weight placed upon the folding stool. The folding stool folds so that the top face of the top wall is coplanar with the outer face of the front side wall when in the folded position.

    Abstract translation: 折叠凳具有梯形侧面，包括前后非折叠侧壁和左右折叠端壁。 每个端壁包括第一和第二非折叠半壁以及将这些半壁彼此连接的铰链。 折叠式凳子包括通过铰链连接到前侧壁的顶部的非折叠顶壁，并且在另一端处在靠近顶壁的中部并且靠近后侧壁的顶部连接的支柱。 当折叠的凳子处于其展开位置时，顶壁从左右端壁和后侧壁水平向外延伸，以搁置在左右端壁和后侧壁上以支撑放置在折叠凳上的重量。 折叠的凳子折叠，使得当处于折叠位置时，顶壁的顶面与前侧壁的外表面共面。

    Abstract: A ladder including a first frame, a second frame and a platform assembly. The first frame includes one or more fixed steps. The platform assembly includes a first platform pivotably coupled to the first frame, a second platform pivotably coupled to the first frame, a first linkage coupled between the second frame and one of the first platform and the second platform, and a second linkage coupled to the first platform and the second platform. The ladder is movable between a closed position and an open position.
