The present invention relates to an integrated folding safety handrail and outdoor escape stairs for high-rise buildings and an emergency escape device which are applied to high-rise buildings such as safety handrails for preventing falling from a movable passage exposed to apartment houses such as apartments or office buildings, and the outside and is applied as a substitute for safety handrails in high-rise buildings or outdoor ground clearance 3 m or more which is usually used as a safety handrail for falling prevention and so that an escaping person in the high-rise building escapes outside or safely escapes to a lower floor in case of emergency such as fire, terror, and disaster. Particularly, the present invention relates to an integrated folding safety handrail and outdoor escape stairs for high-rise buildings and an emergency escape device, including a fence unit 1 in which an entrance unit 10 and a safety fence unit 20 are integrated; and a sliding stair unit 30 formed at a lower end of the fence unit 1.

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.

A stairway (1) comprising a plurality of steps (2) each defining a top surface or tread (3) is converted into a lift platform by employing a mechanism concealed beneath an envelope defined by the treads of all of the steps to guide each step of the plurality vertically from a stairway configuration in which the steps form a stairway enabling access from a lower (7) level to an upper level (8) to a flat configuration in which the top edge of each step is substantially in a horizontal plane level with one of the lower and upper levels from which a wheelchair user may wish to travel to the other of the lower and upper levels. As a result, a wheelchair user may move horizontally from the said one of the lower and upper levels on to a platform defined by the top edges of the plurality of steps in the flat configuration. The stairway and flat configurations occupy the same footprint.

A ceiling ladder having a plurality of sections that can be climbed by a user when in an unfolded position into an attic and that can be folded together into a retracted position to be stored above the ceiling. The ladder has a deep step, which has a width greater than the width of other steps of the ladder, in which is located between about 2-5 feet from the floor when the ladder is in the unfolded position so user can stand on the deep step in place objects into the attic without having to climb into the attic. A method. A deep step.

The present invention relates to a particularly compact and safe extendable access device for gaining access to elevated locations via a hatch opening. The access device comprises a telescopic ladder with a plurality of sliding elements movable between an extended position and a retracted position, each sliding element comprising two stiles connected by a rung. The stiles of each sliding element are interlocked with the stiles of adjacent sliding elements, wherein each sliding element comprises a first locking mechanism for releasably connecting at least one of the stiles to an adjacent stile of an adjacent sliding element, the first locking mechanism being adapted to lock each sliding element in its retracted position. The first locking mechanism of each sliding element is adapted to releasably connect at least one stile of each sliding element to a stile of an adjacent sliding element, which is closer to a top end of the telescopic ladder, and is adapted to automatically disconnect said stiles once an adjacent sliding element, which is closer to a bottom end of the telescopic ladder, is in its extended position. The first locking mechanism is adapted to automatically connect the at least one stile of said sliding element to a stile of the adjacent sliding element, which is closer to a top end of the telescopic ladder, when the adjacent sliding element, which is closer to the bottom end of the telescopic ladder, is moved from its extended position towards its retracted position.

A storm shelter escape door assembly includes a frame and a door hinged to the frame. The frame includes three inner sidewalls, an open end, and a horizontal attachment plate extending outwardly from upper edges of the inner sidewalls. The door has at least three outer sidewalls joined by a door face. The door is hinged to the frame adjacent the open end and below the horizontal attachment plate so the door is openable in an inward direction away from the horizontal attachment plate. When the door is in a closed position, the door face angles downwardly toward the open end to cause water to run off the door.

The invention relates to a device (1) for helping a wheeled vehicle pass over an obstacle, in particular for a person with impaired mobility. It comprises: a stationary frame (2) comprising a bottom and two symmetrical parallel side walls (9, 10); a plate (3) provided with two ends, a first end being movable between a high position and a low position in which said plate constitutes an access ramp, and an assembly for driving said first end between a low position and a high position, said first end being supported by said drive assembly in both the low position and the high position. Said drive assembly comprises: a linear ram mounted under the plate (3), provided with a stationary end adjacent to said second end and rigidly connected to the bottom, and a mobile end, a carriage that is movable in horizontal translation and driven by said ram, said carriage resting on guides mounted on the bottom of the frame. Said carriage comprises two tappets, a pair of arms, the arms being symmetrical, each arm resting on one of the tappets of the carriage, each arm supporting the first end of the plate (3); in the retracted position of the actuator, the carriage is near said second end, the arms are in the low position and the first end is in the ramp position, and in the extended position of the actuator, the carriage is arm said first end, the arms are in the high position and the first end is in the high position.
