摘要： The present invention relates to a safety ladder device primarily comprised of a ladder frame, a plurality of ladder feet, a first outrigger, a second outrigger and at least one safety strap. The plurality of ladder feet may further be comprised of a continuous opening that can receive a ground spike or fastener that allows a user to secure the device to and/or into a nearby surface for stabilization of the device during use. Both outriggers preferably attach to each side of the top step of the ladder frame via a hinge that allows both outriggers to move freely and be placed at a variety of angles to further stabilize the device. In addition, the at least one safety strap is positioned around the device, such that it prevents a user from falling off the device, yet still allows the device to remain fully functional.

摘要： A safety step ladder is formed of a climb leg and a support leg, and includes a specialized hinging arrangement to attach the support leg to the climb leg at a location below the midpoint of the climb leg such that the top portion of the climb leg somewhat overhangs the support leg. The specialized hinging arrangement is also configured so that the support leg is raised upward when closing against the climb leg (ensuring that in the closed position the support leg does not extend below the climb leg), providing a compact configuration for storage purposes.

摘要： A household lift for fallen persons is devised in which a modified stepladder serves as the main lift structure while also serving as a stepladder storably foldable and usable within the house. A removable winch is set atop the stepladder, and it too can serve other purposes and can be of hand-cranked or electric powered design. The winch's lift cable is removably attached to preferably a prior-art sling type which first lays flat on the floor to facilitate moving the person onto it, and next pulls the person up into a secure sit-up position and then high enough to lower onto a wheelchair or other safe destination.

摘要： 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.

摘要： An assembled ladder includes two supporting leg assemblies, at least one rung and a bridging part, wherein each supporting leg assembly of the two supporting leg assemblies includes a front supporting leg and a rear supporting leg rotatably connected to the front supporting leg, and the at least one rung and the bridging part are detachably connected between the two supporting leg assemblies. During logistics transportation, the at least one rung is detached from the two supporting leg assemblies, the bridging part is also detached from the two supporting leg assemblies, and the two supporting leg assemblies are stacked. In use, two ends of the bridging part are fixedly connected to the two supporting leg assemblies, and two ends of the at least one rung are also fixedly connected to the two supporting leg assemblies.

摘要： The present disclosure discloses a folding ladder and a top tray thereof. The top tray comprises a fixed plate and a movable plate. The movable plate is disposed on a rear side of the fixed plate and is rotatably connected to the fixed plate, and the movable plate is configured to be rotated to switch between an unfolded position and a folded position. When the movable plate is in the unfolded position, the movable plate is horizontally arranged side-by-side with the fixed plate, and a rear surface of the fixed plate abuts a front surface of the movable plate to maintain the movable plate in a horizontal position and to resist a downward force of gravity. When the movable plate is subjected to an upward pushing force and is rotated to be folded into the folded position, the movable plate abuts the rear side of the fixed plate.
