Abstract (en)

[origin: EP2578768A2] The stairs have a safety device ( 3 ) for protection against uncontrolled detachment of at least two last segments from the first segment ( 11 ) by rotation on the hinges ( 21 ), which mechanism is positioned near the top ends of the segments, beneficially overlaid on the extension hinge ( 23 ) that joins together segments 2 ( 12 ) and 3 ( 13 ). The safety device ( 3 ) is unlatched by the user lifting the bottom parts of segments 3 ( 13 ) and 4 ( 14 ). Also, the stairs have a bottom lock ( 6 ) installed on the hinge ( 22 ) that joins together segments 3 ( 13 ) and 4 ( 14 ).
