Abstract:
1. A fastening system for rectangular, tabular panels, each of said panels having four small faces, including two sets of two opposite small faces, a first set of the small faces being on a long side of the panel and having first retaining profiles and a second set of the small faces being on a short side of the panel and having second retaining profiles, wherein mutually oppositely disposed retaining first profiles of the long sides of a panel match each other such that similar panels can be interlinked in such a way that, on a panel in a first row, a new panel can be locked in a second row by attaching the new panel to an installed panel in the first row at a temporary angle relative to the installed panel and then swiveling said new panel down into the plane of the installed panel such that the new panel is interlocked vertically and horizontally to the installed panel in the first row, the opposite second retaining profiles of the short sides having corresponding connection elements such that a connection can be established by means of one of the connection elements of a third panel and a connection element of a panel that is already installed in the second row by swiveling down the third panel such that the third panel is interlocked both vertically and horizontally to another installed panel in the first row, wherein each connection has a horizontal locking groove that opens horizontally outward away from the small face and extends along the small face so that in the connected state, the horizontal locking grooves of the panels that are adjacent to one another form a common horizontal locking recess, and an additional locking element that prevents, in a connected state of two panels, the connection between the short sides of the panels from being released in a direction perpendicular to the plane of the installed panels, the locking element is pre-mounted on one of the horizontal locking grooves, and the locking element has a cross-section formed to protrude into a cross-section of the horizontal locking groove of one panel and into a cross-section of the horizontal locking groove of another panel and the locking element resides only in the common horizontal locking recess in the connected state.
