An apparatus includes a platform having a first end and a second end and a handle. The apparatus includes a first leg assembly rotatably attached to the platform in proximity to the first end. The apparatus includes a second leg assembly attentively attached to the platform in proximity to the second end. When the first and second leg assemblies are essentially perpendicular to the platform, the apparatus is in a use state and the user is able to stand on the platform and be supported by the first and second leg assemblies. When the apparatus is in the use state, the user is able to pick up the apparatus by the handle with only one of the hands without tipping the apparatus. A method for a user with hands to stand on an apparatus.

A work platform includes a plank which telescopes to a desired width. The work platform includes a first leg assembly rotatably attached adjacent to a first end of the plank. The work platform includes a second leg assembly rotatably attached adjacent to a second end of the plank. The work platform includes a first linkage attached to a first leg of the first leg assembly. The first linkage may be a first hook or a first strap assembly for securing the work platform to a first support structure. A method for using a work platform. A method for producing a work platform.

A scaffold upon which a person stands includes a platform with a first leg assembly rotatably attached to the platform. The scaffold includes a latch assembly having a latch pivot axis coupled to the platform. The scaffold includes a stud attached to a first leg of the first leg assembly to which the latch assembly engages when the first leg assembly is moved into the extended position to automatically lock the first leg assembly in the extended position where the latch assembly is in a set position. When the latch assembly is moved out of the set position, the stud on the first leg disengages from the latch assembly and the first leg assembly is able to rotate about the first leg assembly pivot axis to a folded position. A method for using a scaffold.

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.

An unlocking structure of workbench ladder includes a platform and two ladders hinged to the two ends of the platform; wherein, the ladder includes an unlocking structure relative to the hinged joint of the platform, and the unlocking structure includes an operating button, rotating lock tongue and a first elastic element; the rotating lock tongue is arranged in the column and the upper end is a locking hook which is locked and located in the locking plate at the bottom of the platform; the first elastic element acts between the rotating lock tongue and the column driving and positioning the locking hook toward the locking plate to lock the ladder and the platform; the operating button acts on the rotating lock tongue to overcome the first elastic element and drive the locking hook to move in a direction opposite to the locking plate, unlocking the ladder and the platform.

A plank scaffold system and, more particularly, to a ladder-based vertically-adjustable plank scaffold system. The system may have a pair of ladders, a wall standoff mounted at the top of each of the ladders, a crane support mounted at the top of each of the ladders, a vertical guide bar and roller system to keep it from swinging on the cables, and a horizontal platform suspended on cables below the crane supports, the platform having a pair of cable winches mounted thereon for varying the elevation of the platform. Instead of ladders, tower scaffolds or stage towers may be used on each side to support the vertically-adjustable plank.
