Abstract:
1. A covering made from mechanically interconnectable elements, wherein at least one of the elements is a panel, the elements comprising: matching profiled sections arranged on opposing sides of a panel and configured for interlocking adjacent elements in a horizontal and vertical direction by a substantially vertical joining motion or a pivoting joining motion, at least one spring element hinged on one of the elements and configured for pivoting during the joining motion behind a locking edge of the adjacent element, said locking edge extending substantially in the horizontal direction wherein the element has a top side and an end of the at least one spring element adjacent to the top side is connected to the element, a supporting surface arranged on the adjacent element facing the locking edge and configured to enable the at least one spring element to slide on the supporting surface, wherein the supporting surface is inclined toward the locking edge with respect to an installation plane, causing a horizontal displacement of the at least one spring element behind the locking edge wherein the at least one spring element contacts the locking edge, or wherein the supporting surface extends parallel to the installation plane and a free end of the at least one spring element is inclined with respect to the installation plane, thereby causing a horizontal displacement of the at least one spring element behind the locking edge wherein the at least one spring element contacts the locking edge when adjacent elements are joined.
