Mounting system with threaded sliding block

A mounting system for fastening solar modules to a mounting surface, comprising:

• (a) at least two spaced apart, profiled mounting rails, each mounting rail having:
• a support defining the height of the mounting rail profile;
• a connector below the support for mounting the rail to the mounting surface;
• threaded sliding blocks, engaging the profiled mounting rail in a form-fitting manner, wherein at least one threaded sliding block is for fastening the mounting rails to the solar modules and at least one threaded sliding block is for fastening the mounting rails to the mounting surface;
• and
• mounting rail connecting profiles arranged laterally on the profiled mounting rail,
• (b) at least two profiled connecting rails, each connecting rail having:
• connecting rail connecting profiles for engaging the mounting rail connecting profiles to generate a form-fitting connection at least at two points between the profiled mounting rail and the profiled connecting rail after engagement of the respective connecting profiles and to establish a force-fitting connection;
• wherein the mechanical load capacity of the profiled connecting rail is approximately that or the same as that of the profiled mounting rail;
• and
• c) wherein a first connecting profile of the profiled mounting rails and a second connecting profile of the profiled connecting rails form a telescopic profile pair;
• and
• (d) wherein the first connecting profiles of the telescopic profile pair each consist of a U-shaped section, with legs having bent ends that are bent inward on one of the connecting profiles and outwardly on the other one of the telescopic profile pairs.
