Slip resistant mat and process of manufacture of same
A slip resistant floor mat composed of one or more layers of material the bottom layer of which incorporates a plurality of recessions in the bottom surface of the bottom layer that comes into intended surface, such as a floor. The mat may be manufactured by using a press mold to form recessions on the bottom surface of the bottom layer of the mat, and if desired, additional layers may be laminated together with the bottom layer.
1. A mat for use on a substantially flat surface comprising:
at least one layer of material having a bottom surface and a top;
wherein the bottom surface has at least one recession therein, the recession having an opening;
wherein the recession is operative to reduce movement of the layer when the opening is in contact with the floor surface;
wherein at least a portion of the recession is cylindrical;
wherein a first recession has a width of about 0.75 inches and a depth of about 0.04 inches; and
wherein a second recession has a width of about 1.0 inch and a depth of about 0.063 inches.
2. The mat as described in claim 1 wherein said material is rubber or plastic.
3. The mat as described in claim 1 wherein said at least one recession is located on at least one of a plurality of straight rows on said bottom surface and wherein said plurality of straight rows are parallel to each other.
4. The mat as described in claim 1 further comprising a second layer and wherein a top surface of said second layer is bonded with a third layer selected from the group consisting of yarn, carpet, and fabric.
5. The mat as described in claim 1 wherein said mat further comprises a first a second layer of said material, each layer having a top surface and a bottom surface, the top surface of said first layer being bonded to the bottom surface of said second layer.
6. The mat as described in claim 4 wherein said mat further comprises a bottom layer, wherein a top surface of the bottom layer is bonded to a bottom surface of the second layer.
7. The mat as described in claim 1 wherein said mat comprises two or more layers of material each of said layers consisting of a different material.
8. The mat as described in claim 7 wherein each of said layers consists of a different variety of rubber having varying flexibilities.
9. The mat as described in claim 6 wherein said bottom layer consists of a rubber compound having a lower durometer reading than said top layer.
10. The mat as described in claim 9 wherein said bottom layer has a durometer reading of less than 45 units and said top layer has a durometer reading of more than 75 units.
11. The mat as described in claim 9 wherein the durometer reading of said bottom layer is at least 25 durometer units less than said top layer.
12. The mat as described in claim 2 wherein said material of at least one layer is impregnated with anti-bacterial materials.
13. A process for producing a mat according to claim 5 , comprising the steps of:
supplying the first layer of material;
press molding the first layer of material;
supplying the second layer of material; and
laminating said first layer and said second layer of material; and
curing said mat.
14. The process for producing a mat according to claim 13 , further comprising the step of pricking said first layer and said second layer.
15. The mat as described in claim 1 wherein a first recession has a different diameter then a second recession.
16. The mat as described in claim 3 wherein said plurality of straight rows comprise alternating rows of a first recession having a first diameter and rows of a second recession having a second diameter.
