The present invention relates to a combination comprising: a rail constructed for climber shoes and fall-preventing means and adapted for mounting to posts, masts, construction elements, chimneys or the like; a pair of climber shoes constructed for coaction with such a rail; and a fall-preventing means constructed for coaction with such a rail and including a runner adapted to run along the rail. The novel feature of the invention is that the rail consists of a preferably hollow web portion of rectangular cross-section having flanges arranged pairwise and projecting from opposite edges of two opposite sides, and that those portions of the two sides of the web portion which are situated adjacent the flanges are adapted to form abutment surfaces for engaging portions in both the oppositely directed flanges for the gripping members of climber shoes, fall-preventing means or the like gripping the respective web portion edge, that the climber shoe includes opposite projections adapted to engage with the flanges and abutment surfaces, and that the fall-preventing means includes pairwise opposite projections facing abutment surfaces which face away from each other and antifriction means which in a certain position permits displacement of the fall-preventing means along the rail. |
