Covering from mechanically interconnectable elements

摘要

A covering from mechanically interconnectable elements, wherein at least one of the elements is a panel, wherein the elements have on their confronting sides a complementary profiling and can be locked together via said profiling. The locking is caused by at least one tongue element which is connected to one of the elements in an articulated manner and which can be pivoted during the joining motion behind a locking edge of the adjacent element, said locking edge extending essentially in the horizontal direction. The tongue element is in part connected to a core of the element by means of an elastic material and is a one-piece component of the element prior to the joining motion, wherein the one-piece connection between the tongue element and the element is configured as a predetermined breaking site which is provided to fail, in particular break, when the tongue element is pivoted.

主权项

1. A covering, comprising:
plural elements mechanically connectable to one another, with confronting sides of opposite elements having a complementary profiling for allowing the opposite elements to be locked with one another by at least one tongue element hinged to one of the opposite elements for pivoting during a joining motion behind a substantially horizontal locking edge of the other one of the opposite elements, said opposite elements and said tongue element being made of a same first material; and an elastic material for connecting the tongue element at least in part with a core of the one of the opposite elements, said elastic material being made of a second material different from the first material, wherein the tongue element is formed one-piece with the one of the opposite elements before the joining motion via a predetermined breaking point adapted to fail when the tongue element is pivoted.
