FOLDING LADDER
Folding ladder (1), in particular for accessing the cavity of a lift shaft comprising: a first side rail (2) and a second side rail (3) that are parallel; a plurality of rungs (10); a stop (15) located on the first side rail (2); a locking member (16) located on the second side rail (3); a locking arm (34) having a first end portion (34a) pivotally attached to the first side rail (2) and a secondend portion (34b) that is movable between an unlocking position in which it is magnetically coupled to the stop (15) so that the locking arm (34) abuts the first side rail (2), and a locking positionin which it is magnetically coupled to the locking member (16) so that the locking arm (34) is diagonally arranged with respect to both the side rails (2, 3).
折叠梯(1)，具体地用于接近升降机井的腔，该折叠梯包括：平行的第一纵梁(2)和第二纵梁(3)；多个横档(10)；止挡部(15)，位于第一纵梁(2)上；锁定构件(16)，位于第二纵梁(3)上；锁定臂(34)，具有枢转地附接到第一纵梁(2)的第一端部(34a)以及能在解锁位置与锁定位置之间移动的第二端部(34b)，在解锁位置中，该第二端部磁耦接到止挡部(15)，使得锁定臂(34)邻接第一纵梁(2)，在锁定位置中，该第二端部磁耦接到锁定构件(16)，使得锁定臂(34)相对于两个纵梁(2、3)对角地布置。
