Abstract:
1. A device for laying floor and wall coverings in reentrant corners comprising an independent corner insert made of a same material as a covering and having same structural and decorative characteristics as the covering, said corner insert being flat before the insert is laid in a corner, and being deformed in situ in the corner, and being defined in three dimensions after the insert is laid in the corner and having, when flat, a geometrical configuration of irregular lines so that, after the insert is laid in the corner, a peripheral outline of said insert has a regular parallelepiped geometrical configuration, and wherein said insert comprises first and second triangular areas with bases that are part of the peripheral outline of the insert and a third triangular area with an inner base not part of the peripheral outline, wherein by consecutive juxtaposition of the first and second triangular areas flat against successive walls and the third triangular area flat against a floor of the corner, a fourth triangular central area of the insert is formed by insert deformation in situ which slopes after laying and is located in a forward plane away from a corner area where the successive walls and the floor meet, said fourth triangular central area constituting a visible easy-to-access surface for cleaning and making it possible to dislodge and collect dust and other particles on a base of said triangular central area.
