ABSTRACT:
A foot support for profiled sections has a base member; a receptacle for the profiled section arranged in the base member; and several tensioning levers having a horizontal pivot axis and arranged about an axis of symmetry. The tensioning levers are pivotable between a rest position and a clamping position about the horizontal pivot axis. The tensioning levers have a lower lever arm positioned below the horizontal axis and an upper lever arm positioned above the horizontal pivot axis. A foot-actuated actuating element that acts on a force-transmitting element, acting on the tensioning levers for moving them into the clamping position, is provided. The force-transmitting element is a vertically adjustable ring that, when carrying out a downward movement, contacts the lower lever arms of the tensioning levers such that the lower lever arms are pivoted outwardly and the upper lever arms are pivoted inwardly into the clamping position.
