Abstract: A cover for closing an access opening that leads to an infrequently used space within a building, such as an attic, provides thermal and acoustic insulation at the access opening. The cover may be in one or two portions, including a closure alone or a closure and a frame having an aperture that can be closed by engagement between the closure and the frame. When the cover is used alone it engages a frame or a wall circumscribing the access opening. The cover is sized and shaped to close a hatch, a stairwell, the opening at one end of a stairway, or an opening in a generally vertical wall that is not necessarily associated with a stairway. The closure and frame are each made of one or more components.

Abstract: An aircraft 1 comprises a walkway 11 moveable between a stowed position and a deployed position. The aircraft may be arranged such that the walkway, in the deployed position, defines a path, at least a portion of which extends from the fuselage at an angle, when viewed from above, of less than 90 degrees to the longitudinal axis of the aircraft. The walkway 11, in the stowed position, may be located at an angle, when viewed from above, of less than 80 degrees to the longitudinal axis of the aircraft. The opening 9 may be located in a region extending from 20% to 80% of the total cabin length. The walkway may be further moveable to a second deployed position. A longitudinal portion of the walkway 13, in the first deployed position, may define a stepped surface having a first step height, whereas that longitudinal portion of the walkway 13, in the second deployed position, may define either (a) a substantially even surface, or (b) a stepped surface having a second step height, the second step height being less than the first step height.

Abstract: An automated pivoting stairway system that raises and lowers through use of a drive actuator to thereby provide access to above or below floor level areas or between an elevated area and the ground floor. The system may utilize modular sections to allow on-site assembly. The stairway may be pivoted at the top of the stairway by way of a pivot drive lever attached on either side of the top step pivot frame assembly so that access on or off the stairway may be directly off the front end of the stairway, or to either side. A separate frame member may extend from the pivot point along the side of the stairway opening to a predetermined distance. This frame member may serve as the anchor point for the base end mount of the actuator.The actuator controls the length of stroke and the amount of torque that is required to operate the stairway up and down.

Abstract: A combined stairway and lift installation has a stairway which comprises a stack of horizontally movable step members whereby the stairway is retractable to expose a lift which is installed in a cavity which is covered by the stairway when the latter is extended. Uncovering of the lift allows it to be operated to raise its load carrying platform to the level of the top of the stairway. A chain is anchored by either end in the bottom step member. The chain is led from the anchorage up through the step members, alternately clockwise and counter clockwise around guide rollers mounted in each of the movable step members, clockwise around a guide roller and a motor-driven cog wheel in the top step member, and back down through the movable step members to the other anchorage again alternately clockwise and counter clockwise around further guide rollers mounted in each of the movable step members. The motor is reversible so that in one sense it drives the movable step members to form the stairway and in the other sense it drives them to their retracted position.

Abstract: In accordance with the present disclosure, a portable riser unit for supporting persons or objects above the ground, a floor, a stage or the like is provided. The riser broadly comprises a base, generally rectangular step members, and hinge joints for pivotally, hingedly connecting the step members to the base. The base has an integrally formed, convoluted internal or interior support and baffle wall structure and may be filled with an appropriate low density, high volume material. Each step member also may be of this construction; however, the step members may or may not have an internal support wall. The step members are operably coupled to the base by double axis hinges including hinge blocks received in complementary hinge wells in the base and step members. The hinges are self-leveling to present a substantially smooth, level riser support surface in every possible configuration. The riser may be molded of a plastic material and includes integral hand grips to facilitate moving step members or the entire riser. By manipulating the step members, the riser may be re-shaped into a variety of operable configurations. The invention also encompasses connector keys for connecting two or more risers into a riser assembly.

Abstract: An emergency escape openable skylight is provided with a resiliently biased openable cover with at least a substantial portion of the openable cover being constructed of a transparent material. The skylight is provided with a retractable ladder. The retractable ladder may be a pully operated flexible ladder, a rigid foldable ladder, or any other suitable retractable ladder. The cover is normally held closed by a latch means, but is self-opening or substantially self-opening upon release of the latch by reason of the resilient biasing means.
