APPARATUS, SUCH AS A LADDER, COMPRISING EXTENDABLE LEGS

摘要

The invention relates to a supporting element (2) for an object. The supporting element comprises a first leg member (22) and a second leg member (20). The first leg member is axially movable relative to the second leg member for axially extending the support member. The first leg member comprises a house (32) that is arranged for slidably receiving the second leg member. The house comprises a locking element (30) having a locking position for locking the relative axial movement of the first leg member with respect to the second leg member, and having an open position for enabling relative axial movement of the two members. A catch (34) may be provided in the locking element. The catch may be tiltably movable within the house for alternately acquiring the locking position and the open position of the locking element. The catch may comprise a cavity (40) receiving the second leg, wherein the cavity has a stopping surface (47) engaging at least opposed perimeter parts of the second leg member in a locking position of the locking element.
