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.

A lapboard for a safety deck assembly, the safety deck assembly comprising a upper deck formed of one or more decking panels having a substantially planar upper surface and an elevated support assembly comprising a number of elongate legs, a base for each elongate leg to form a foot, a head for each elongate leg to at least partially support a decking panel relative to an upper end of the leg, the lapboard comprising a substantially planar upper surface and at least one receiving opening formed in an underside of the lapboard to receive a portion of the head to locate the upper surface of the lapboard substantially coplanar with the upper surface of the decking panels, the lapboard being smaller in width than the decking panels.

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.

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 trestle including: a base intended to rest on the ground, formed of two pairs of posts parallel to each other, the two posts of each of the pairs being secured together at least by an upper crossbar, said pairs being secured together at the level of at least one upper joint, and a support surface arranged above the base and secured to said base, and extending perpendicularly to a vertical direction when the trestle is in working position.

The upper crossbars extend between the two posts parallel to each other of each of the two pairs and are secured thereto by gluing.

Lateral assembly panels or corner pieces are fastened at least at the level of the upper angles defined by the posts and the associated upper crossbar of each of the two pairs of posts, and on either side of said upper angles.

The upper end of each of the posts is tapered, so that, in working position, the support surface rests on the entire upper section of said posts.

The support surface is only secured to one of the two pairs of lateral posts.

An apparatus for setting up a ladder or a step on a staircase comprises: a platform on which the ladder or the step can be set up; and a frame to support the platform on the staircase. The frame comprises at least two legs each pivotable about a common pivot axis or about respective pivot axes, wherein the common pivot axis or the respective pivot axes lie in a plane of the platform or parallel to the plane of the platform.
