Panel and fastening system for such panel

A panel for use in a fastening system which has a separate locking element, the panel comprising:

• a body having a rectangular, tabular shape and small faces;
• retaining profiles arranged on the small faces;
• the retaining profiles arranged on opposite small faces being configured to fit together in such a way that similar panels are connectable to one another;
• the retaining profiles on the opposite small faces of each panel are formed as first retaining profiles and on remaining small faces of the panel as second retaining profiles;
• the first retaining profiles are formed in such a way that a new panel located in a second row of panels is lockable to a horizontal panel located in a first row of panels, wherein the first retaining profile of the new panel is initially joined to the horizontal panel in an inclination relative to the horizontal panel and is subsequently pivoted downwards into a plane of the horizontal panel;
• the oppositely located second retaining profiles have corresponding hook elements and wherein with one of the hook elements of the new panel and a hook element of a panel already located horizontally in the second row a hook connection is producible by pivoting the new panel downwards;
• an additional locking element is assignable to each hook element, which in the hooked state of two panels prevents a release of the hook connection in a direction perpendicular to the plane of the installed panels;
• each of the hook elements of the oppositely disposed small faces of a panel have a locking groove, which extends in a longitudinal direction of the small face and opens in a direction substantially parallel to the plane in which the panels are installed;
• the locking grooves are provided on surfaces of the hook element which in an installed position of the panels are aligned substantially perpendicular to the plane in which the panels are installed;
• the locking grooves of two panels abut each other in a connected condition of the hook elements and form a common locking clearance;
• the locking clearance is formed in such a way that a locking element of the fastening system is insertable into the locking clearance formed by the locking groove(s) by way of insertion or driving, such that the locking element in an already locked condition of two panels is insertable into the locking clearance in such a way that a cross section of the locking element projects at least partially into a cross section of the locking groove of one of the two panels and partially into a cross section of the locking groove of the other of the two panels;
• and
• faces of each hook element aligned substantially perpendicular to the plane of the panel and provided with the locking grooves are arranged in such a way that the faces extend away from the small face of the respective panel to the outside.
