Abstract (en)
[origin: EP2108761A2] A folding attic stair assembly (1) comprises a rectangular outer mounting frame (2). An inner stairway carrying frame (3) is mounted by a hinge (4) at one end of the outer mounting frame (2) for movement between a raised stored position on the outer mounting frame (2) and a lowered position extending downwardly from the mounting frame (2). An expendable attic stair (5) is mounted on the inner frame (3). A pair of folding support arms (6) extend between the outer mounting frame (2) and the inner stairway carrying frame (3). A cable (8) connects between each folding support arm (6) and an associated reel (9) mounted on a drive shaft (10) which is connected to a drive motor (11). This drive motor (11) is operable to wind and unwind the cables (8) on the reels (9) to raise and lower the attic stair (5) in a controlled manner.
