Abstract: A wirelessly electrically-coupled deployable apparatus comprising a deployable structure supported on a supporting structure for motion between a stowed position and a deployed position, an electrically-powered device carried by the deployable structure, a wireless electrical power receiving circuit carried by the deployable structure and connected between the device and a wireless electrical power receiver, and a wireless electrical power transmitting circuit carried by the supporting structure and connected between an electrical power supply and a wireless electrical power transmitter. The wireless electrical power transmitter is carried by the supporting structure, and the wireless electrical power receiver is carried by the deployable structure, in respective positions where wireless electrical power transfer between the wireless electrical power transmitter and receiver powers the device via the receiving circuit when the deployable structure is in its deployed position.

Abstract: A stowable stair assembly with step treads connected between stair stringers includes stabilizing legs positioned within a width of the treads and behind the treads. A removable hinge assembly facilitates installation of the stair assembly as well as access to the stair assembly.

Abstract: A step stabilizer leg is adjustable in both the angle and length of the leg. The legs are also individually adjustable to accommodate for uneven ground and are lockable and stowable with the step when it is not in use. A plate that mounts the stabilizer leg to the bottom of the step has multiple apertures that correspond to one of a few apertures adjacent to or integrated with the leg. This allows for the leg to be placed in different angles with respect to the step, including an angle that projects backwards towards the step assembly for situations when the bottom step is very close to the ground.

Abstract: A stair assembly may include a plurality of steps, a main stringer pivotably connected to a corresponding lateral end of each of the plurality of steps, and a support stringer pivotably connected to a corresponding lateral end of each of the plurality of steps, wherein the main stringer and the support stringer are movably connected to the plurality of steps such that the rise and the run of the plurality of steps remains consistent when the main stringer and the support stringer are moved relative to each other.

Abstract: A system includes a structure having a wall, a doorway and a door that is repositionable between a first position wherein the door is clear of the doorway and a second position wherein the door occludes the doorway. The system also includes a stair carrier attached to the structure. A stair may be connected to the stair carrier. The stair carrier is repositionable between a first position wherein the entirety of the stair carrier is disposed on a first side of the wall and a second positon wherein a portion of the stair carrier extends through the doorway to a second side of the wall. The door is fully operable between the first position and the second position both when the stair carrier is in the first position and in the second position.
