Grid-Shaped Mat

Abstract

Disclosed is a grid-shaped mat which is used especially for protecting floors or strengthening a floor cover. Said grid-shaped mat comprises a number of strip-shaped elements ( 1, 1′; 1″ ) which are bent several times, extend in a longitudinal direction (A), and form the grid structure of the mat ( 10 ). The lateral length (b) of the element ( 1, 1′; 1″ ) that is longer from a cross-sectional perspective runs perpendicular to the longitudinal direction of mat. At least two adjacent elements ( 1, 1′ ) are hingedly connected to each other with the aid of at least one pin ( 2 ) that extends in the longitudinal direction (A) of the elements, respectively. Such a mat is easy to produce while the floor cover that is applied to the mat coheres significantly better after drying and hardening than when a conventional wire grill is used.
