A folding ladder comprising two ladder frames rotatably connected by two oppositely arranged frame hinge assemblies at the top, the ladder frames each including two parallel ladder legs, and several ladder frames; the frame hinge assembly is provided with a balancing member, one end of the balancing member is hinged with one frame hinge assembly, and the other end is connected with another frame hinge assembly in a locking manner; each step comprises hinged left and right step sections, the tops of the two ends of each step are is with snap-fit notches, so that the steps do not collide with the legs during the rotation process, the steps are in contact with the legs in both the unfolded and folded states, which makes the overall structure compact and has better shockproof effect, which is convenient for the transportation of the whole folding ladder.

The Folding Ladder system is comprised of a square edge Double Sided Folding Step Ladder and a square edge Straight Folding Ladder. Both Ladders are collapsible and fold at each Step level which allows the Ladders to fold to a fraction of their normal size. The square overlapping Sections are unique to these ladders. They looks like regular ladders but on closer examination each Section collapse on the Section below which creates a stock up effect that cause the ladder to fold to about a quarter of its original size. The Double Sided Folding Step Ladder has Angled Uprights at the Bottom Section which gives it a wider base which prevent side tip over. The Top Step of both Ladders is not a Step. It is a storage compartment with rounded top not suitable for standing. An access door in the top of the Compartment give access where small tools and parts can be put away safely, without falling if the occupant moves the Ladder.

A foldable stepladder in accordance with the present disclosure may be changed by a user from an expanded use mode to a collapsed storage mode. The foldable stepladder includes a handrail that moves to reduce the overall height of the stepladder when in the collapsed storage mode.

A ladder having a first rail having a bottom and a web, a first flange attached to a first end of the web and a second flange attached to a second end of the web. The ladder having a second rail. The ladder having rungs attached to the first rail and second rail upon which a user steps to climb the ladder. The ladder having a foot having a plastic body with a recess which receives the end of the first rail and is positioned about and conforms to the web and the first and second flanges of the first rail. The foot has a plastic base having a top side from which the body extends. The base has an edge positioned about the body with perforations, and a rubber tread disposed along a underside of the base and extending through the perforations and along the edge on the top side of the base to form an overmolded portion of the tread that attaches the tread to the base without any mechanical or other types of fasteners. The rubber tread forms a bond with the underside of the base and the edge on the top side of the base. The foot for a bottom of a rail of a ladder. A method for placing a ladder. A method for producing a foot for a bottom of a rail of a ladder.

A step stool includes an expandable tray assembly. The expandable tray assembly has a fixed tray panel and a movable tray panel coupled to the fixed tray unit for movement relative to the fixed tray unit. The movable tray panel is illustratively movable between a collapsed position, arranged above the fixed tray panel, and an expanded position, arranged adjacent to the fixed tray panel.

A collapsible ladder that collapse not only the rails but also the steps, as well as the top caps, so that the ladder may be erected and then collapsed flat, saving storage space.

The ladder has a pair of right siderails rotatably connected to a pair of left siderails. The right top cap and the right steps are rotatably attached in between the pair of right siderails. The right top cap and the right steps are also rotatably attached in between the pair of right linking rails. Likewise, the ladder also has a pair of left siderails rotatably connected to a pair of left siderails. The left top cap and the left steps are rotatably attached in between the pair of left siderails. The left top cap and the left steps are also rotatably attached in between the pair of left linking rails.

Because the siderails, the steps, the linking rials are all rotatably attached to form the ladder, the ladder may be open and erected and also may be folded and collapsed to save space for storage and for carrying.

An elevator car includes a car floor; a movable ceiling, which is pivotable between a normal operating position, in which the movable ceiling extends substantially horizontally and a maintenance position, in which the movable ceiling extends into an interior space of the elevator car; a working platform movably attached to the movable ceiling. The working platform is pivotable between a storage position, in which the working platform extends basically parallel to the movable ceiling, and a working position, in which the working platform extends transversely from the movable ceiling; and at least one foldable leg attached to the working platform. The at least one foldable leg is foldable between a storage configuration, in which the at least one foldable leg extends substantially parallel to the working platform, and a working configuration, in which the at least one foldable leg extends transversely from the working platform for supporting the working platform.
