  • Patent number: 10428531
    Abstract: A foldable staircase that can be easily transported and conveniently used rather than a ladder. The foldable staircase includes a lower staircase and an upper staircase. The upper staircase and the lower staircase are constructions that bridge vertical distances and provide platforms allowing the user to walk up or down the foldable staircase. The foldable staircase provides an alternative means to reach high areas that is easy and safe to ascend or descend as conventional stairways and staircases along with the transportability of a conventional ladder. The foldable staircase can be adjusted to a collapsed configuration or operative configuration. The collapsed configuration allows a user to store or easily transport the foldable staircase. The operative configuration allows the user to ascend or descend the foldable staircase.

  • Patent number: 8272477
    Abstract: Novel stowed staircases for attics and the like that exhibit highly effective fireproof properties are provided. The combination of sheet metal well sides with ceramic paper covering, a combination thermal board and cement-like construction door, coupled with a sealed gasket at the interface of the stair bottom with the ceiling provide the necessary long-term fireproof capabilities as well as facilitation in installation as a sufficiently lightweight article. In such a manner, the inventive stairway construction may be easily incorporated within a residential or other type unit to aid in the simultaneous accessibility to an attic (or like location) and ability to prevent fire from easily spreading into or out of said attic via the stair assembly itself.

  • Patent number: 7621374
    Abstract: A sectional overhead ladder with a fold assist feature for controlling the extension of the sectional overhead ladder. The fold assist feature of the sectional overhead ladder limits the possibility of free extension of the extendable overhead ladder by preventing gravitational forces from causing the ladder sections to fall into their extended configuration. The sectional overhead ladder includes generally a stair structure and an extendable dampening system. The extendable dampening system is comprised of a dampener and, optionally, a housing. The stair structure includes a first section and a second section. The dampening system is attached to the first and second sections of the stair structure such that the dampener limits the free extension of the stair structure and assists with the collapse of the stair structure.

  • Patent number: 7587866
    Abstract: An integrated insulated housing system with handrails and a system of seals for a pull down stairway opening is provided. The integrated housing system reduces air convection, moisture loss and dirt infiltration. The insulation of the housing system reduces heat loss. Handrails as part of the system are deployed by the action of the pull down stairway. No manual intervention is required. As the stairway is pulled down for use, the integrated housing above moves away from the access opening. Simultaneously, the two integrated handrails move into a stable position on the upper floor and to either side of the stairway. As the stairway is returned up to its closed position, the connected insulated housing moves back into position sealing the access opening.
