<p>The invention relates to sliding shelves for containing flat materials such as large-size, heavy sheets made of various materials. The invention is characterized in that, multiple sliding trays have been mounted in a substantially rectangular and height-variable frame. Said trays can slide due to the roller bearing located on said trays and to another two bearings located on the side of the frame on which the trays are supported. The shelves are modular and the elements that form part of said shelves such as small pillars, longitudinal beams and crossbeams forming the frame are assembled using appropriate screws. Said shelves have a tray end travel safety catch and a safety locking device that enables actuation on any of the trays while immobilizing all other trays.</p> |
