A collapsible work platform includes toprails engaging fixedly to a platform, backrails engaging the toprails pivotally through a hinge at an end portion of the pair of toprails, frontrails engaging the toprails pivotally through a hinge at the other portion of the toprails, link bars engaging the toprails pivotally, a footstep engaging the link bars and the frontrails pivotally, and braces engaging the backrails and the frontrails, and the toprails pivotally through hinges. Each of latching plates having a latching portion engages fixedly the end portions of the backrails and the frontrails maintaining the deployed state by the braces. Each of stopper blocks engage protrudingly an inner side and an outer side of one end and the other end of the toprails, so that the latching portion of the latching plate contacts and engages fixedly and the backrails and the frontrails are not deployed further beyond a certain point.

A work platform system having a first work platform. The system having a first bracket attached to the first scaffold and extending below and outward beyond the first scaffold between the first rail and the second rail of the first leg assembly. The system having a second bracket attached to the first scaffold and extending below and outward beyond the first scaffold between the first rail and the second rail of the first leg assembly. The system having a second work platform. The first end of the second scaffold is disposed on the first bracket and the second bracket with the first bracket and the second bracket extending between the first rung of the third leg assembly and the second scaffold. A method for using a work platform system.

A foldable quad-chord truss which can be connected end-to-end with like trusses. Each pair of chords are rigidly attached, and connector members intermediate the ends are swivelly attached to the chord pairs to effect the folding into a compact shape for transport and storage. The connector members are adapted for attachment to connector members of beams which may extend perpendicular to a parallel pair of the trusses and attached thereto. The laid trusses and beams is overlaid with sheets of corrugated sheet metal which overlap each other along their adjacent edges. While standing on a sheet of laid sheet metal adjacent ends of an already laid pair of trusses, another truss can be held adjacent the edge of the sheet metal for attaching an end of the other truss along only one side so that it can then be swung outwardly into a position wherein the other end of the other truss can also be attached to rigidly connect the trusses end-to-end.

A platform system is configured to allow an individual to be supported at a plurality of different heights, and includes a frame defining a plurality of platform adjustment levels, and an upper support platform that is configured to be selectively moved between the plurality of platform adjustment levels to provide the plurality of different heights.

An extendible scaffold unit comprises at least two support platforms or two support frames (12, 14, 16), at least one of the support platforms or support frames (12, 14, 16) being movable between a lowered position and a raised position, a plurality of scissor linkages (35, 36, 37) linking one support platform or support frame (12, 14, 16) with a next support platform or support frame (12, 14, 16), each of the scissor linkages (35, 36, 37) including a plurality of legs (26, 28, 30, 32), each scissor linkage having a leg pivotally connected to or near a corner of one of the support platforms or support frames and a leg pivotally connected to or near a corner of a next support platform support frame, wherein a leg is pivotally connected at or near each corner of a support platform or support frame. By providing a leg pivotally connected at or near each corner of a support platform or support frame, the support platform or support frame is supported at or near each corner when in the raised position. This provides a stronger, more stable and more secure support to the platform/frame.

A platform erected by adding an other platform portion to an existing platform portion, as illustrated in FIGS. 20 to 23, by holding a first other truss adjacent decking of the existing portion, connecting ends of sides of the first other truss and a first existing truss with a first pin, swinging the first other truss about the first pin, and connecting ends of other sides of the first other truss and first existing truss with a second pin. In order to similarly connect a second other truss to a second existing truss, the first pin is removed and the first other truss is swung out of the way. After the second other truss is connected to the second existing truss, the first other truss is swung back into position and the first pin re-inserted. Decking is applied to the first and second other trusses.

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.
