<p>A folding loft stair assembly (1) has an outer mounting frame (2) for mounting in a ceiling ope giving access to an attic space in a building. An inner stairway support frame (3) is pivotally mounted on the outer frame (2) for movement between a nested position within the outer frame (2) and a downwardly extending In-use position, A two-art collapsible stairway (4) is movable on the inner frame (3) by a remotely controlled actuator (5) between a raised collapsed stored position and lowered in-use position. The stairway (4) Includes an upper part (30) and a lower part (31 ) hingedly connected (38) to the upper part (30). An upper end of the upper part (30) Is hingedly mounted on the inner frame (3). The lower part (31) is slidably connected to the inner frame (3) by a pair of slide arms (40). An inner end of each slide arm (40) is pivotally connected to the inner frame (3) and an outer end of the slide arm (40) slidably engages a slide rail (42) on the lower part (31)</p> |
