(57) In a method for keeping a readily removable mat or similar small carpet (5) in place
in a carpeted or carpet tile covered floor area (1), whereby the mat (5) is provided
with a surface pattern of engageable means, such as protrutions (6), projections or
cleats, distributed all over its lower side, one or more parts (2) of the floor area
(1) to be covered by the mat (5) is kept or made free from carpeting or carpet tile
covering, said one or more uncovered parts (2) of the floor area (1) is covered with
an anchoring plate material (7), the upper surface of which is adapted to be flush
with the upper surface of the carpet or carpet tile covering and in a way known per
se is also performed with engageable means, such as cleats or projections, to engage
the lower side of the mat (5) between its engageable means for preventing lateral
displacement of the mat relative to the anchoring plate material, whereby the mat
(5) is laid in place for at least covering the anchoring plate material (7) and for
providing engagement between its lower side and the upper surface of the anchoring
plate material (7) by means of said engageable means, and the anchoring plate material
preferably having a thickness and a compressibility essentially corresponding to that
of the carpet or carpet tiles of said covering. Thereby is obtained that a mat may
be easily replaced and no risk occurs for the people walking on the carpeted area
(1) during that phase of the replacement where one mat has been removed but the replacement
mat has not yet been laid in place.
