Abstract
A floor mat of the type comprising crossed, interlocking flexible strips which are arranged in grid-like fashion. A plurality of interchangeable design elements are inserted in the rectangular interstitial spaces between the strips at various places on the mat so as to form any desired wording, design or pattern in matching or contrasting colors. The design elements, which substantially occupy the interstitial spaces, are provided with a pair of protruding lugs which interlock with suitably positioned apertures in the strips.

A mat comprising:
- a plurality of parallel flexible first strips and a plurality of parallel flexible second strips extending transversely to and intersecting said first strips so as to form a grid of readily deformable grid squares each comprising a quadrilateral interstitial space bordered by an adjacent pair of said first strips and an adjacent pair of said second strips,
- a plurality of interchangeable insert element means disposed respectively within various of said interstitial spaces, and
- means associated with said insert element means and the strips bordering their respective said interstitial spaces for removably locking said insert element means in their respective said spaces.
A mat comprising:
- a series of parallel elongated flexible first strips,
- each of said strips having a plurality of longitudinally spaced openings, said openings of each of said strips being aligned with openings of the other said strips so as to form a plurality of parallel rows of openings which extend perpendicularly to said first strips,
- a series of elongated flexible second strips extending respectively through said rows of aligned openings and being locked therein so as to form an orthogonal grid of readily deformable grid squares each comprising a quadrilateral interstitial space enclosed by an adjacent pair of said first strips and an adjacent pair of said second strips,
- a plurality of rectangular, interchangeable insert element means disposed respectively within various of said interstitial spaces, said insert element means being substantially congruent to the spaces in which they are disposed, and
- means associated with each insert element means and its respective said interstitial space for removably locking said insert element means in place comprising lugs on two sides of said insert element means which are slidably insertable in cooperating second openings in two of the strips bordering said interstitial space along directions normal to their respective said insert element sides.
