Abstract

A device or reducing the risk of a slide in a shaft consisting of at least two opposite sidewalls and these connecting distance elements. At least one of the elements (3, 4) can be swivelled relative to the walls (1, 2) in a plane primarily parallel to these between an initial position, where the upper sections (8 - 11) of the elements are relatively at a greater distance from each other, and a second position where these sections are relatively at a smaller distance from each other.<IMAGE>
