ABSTRACT:
BACKGROUND OF THE INVENTION
1. Technical Field
The present invention relates to a floor mat for use with a chair. In particular, the present invention relates to a floor mat having a decorative pattern and on which a chair, such as a desk chair, may be used.
2. Description of the Prior Art
A typical floor mat for a use with a chair, such as a desk chair, is made of clear or translucent plastic material. Thus, a viewer is able to see the carpet on which the floor mat is placed. The floor mat is not, however, invisible, and can be visually out of place in an office environment.
The floor mat, because it is clear, must be made from a relatively high quality material, free of imperfections or color. Such a material is relatively expensive.
SUMMARY OF THE INVENTION
The present invention is a protective floor mat for use in supporting a chair on a floor. The floor mat comprises a mat base for contact with the floor, and a graphic layer having a decorative pattern. A first adhesive material is disposed between and interconnects the mat base and the graphic layer. The floor mat also comprises an upper protective layer for contact by the chair. A second adhesive material is disposed between and interconnects the upper protective layer and the graphic layer.
The mat base

may be made from a plastic material such as regrind or reprocessed material, because it is not visible in the finished mat. Use of such a material can result in significant cost savings as compared to using a first quality floor mat material, which must be clear and free of imperfections or color.
The decorative pattern on the graphic layer of the mat is visible through the upper protective layer, to provide an improved appearance to the floor mat.
