Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION This invention relates generally to rubber-backed dust control floor mats of the type having a pile surface on one side and a rubber or rubber-like material on the other side. Mats of this type are commonly used in passageways where people tend to dust or scrape their feet to prevent the transport of moisture and / or dust on footwear to other areas of the building. You. Typically, these mats are installed in busy areas such as doorways.

[0002]

BACKGROUND OF THE INVENTION In recent years, dust control mats such as those disclosed in U.S. Pat. No. 4,761,065 have been developed to prevent the mat from moving when placed on a surface to be protected.
The bottom surface is formed with an anti-slip body. Various types of anti-slip shapes and arrangements that provide anti-migration properties have been used, but there have been problems associated with them.
Most of the included non-slip bodies are very small, and many of these anti-slip bodies have a constant spacing across the back of the mat. The molding pad used to form the pattern is difficult and expensive to manufacture due to the many holes in the pad required to extrude the rubber through it to form the non-slip during vulcanization. This has led to problems in molding since they are subject to tearing and have a reduced service life. In addition, dust control mats having a large number of small anti-skids on the backside caused excessive amounts of lint during processing in the washing machine due to the loss of pile fibers from the surface of the mat.

[0003]

SUMMARY OF THE INVENTION It is, therefore, an object of the present invention to provide a dust control mat having a new and improved anti-slip arrangement on its backside. Other objects and advantages of the present invention will become more readily apparent as the invention is described with reference to the drawings.

[0004]

In a preferred embodiment of the present invention, a mat 10
Comprises a pile yarn 14 such as nylon, cotton, polyester, etc. tufted through a woven or non-woven substrate 16 of a suitable material, the bottom 18 of which is attached to a rubber or rubber-like backing 20 during vulcanization. Glued. A number of anti-slip bodies 22 and 23 are integrally molded or fixed with the bottom of the backing 20. Each mat typically has a border 24 around its periphery.

[0005] The anti-slip body 22 is elliptical, and its major axis is substantially longer than its minor axis. In other words, the length of the anti-slip body 22 is substantially five times its width. In a preferred embodiment of the invention, the floor or surface that engages the surface of the anti-slip body is roughened or roughened to increase its frictional resistance.

As shown in FIG. 2, all the antiskids in any one row are parallel to each other and substantially perpendicular to the antiskids 22 in the adjacent row. Preferably, the long axis of each anti-slip body is approximately 45
Make an angle of °. It can be seen that the non-slip body 22 has about two anti-slip bodies per 4 square inches of the back of the mat and has a wide space between other anti-slip bodies.

The antiskids 23 in each row are in a plane and substantially parallel to the antiskids 22 in the next row.
Then they have equal distance intervals. In a preferred embodiment of the invention, there are six substantially circular antiskids 23 in each line between the antiskids 22, but this number is only preferred and other numbers of slips if desired. The prevention body 23 may be used. The limited number of circular anti-skids 23 in the arrangement shown is significant when installed on a loop pile carpet if the diameter of each circular anti-slip does not exceed 3/32 inch. In addition, maintain high resistance to mat movement. As can be readily seen, the plane through the circular antiskid 23 in each set is at an angle approximately equal to the angle of the long axis of the antiskid with respect to the border 24.

The above-described anti-slip arrangement provides substantially the same firm floor mobility as that of a flat backside design, but is significantly better than the small anti-slip which is widely used in modern dust control mats. It has mobility. In addition to improved mobility, the new anti-slip pattern provides a larger size anti-slip, requiring substantially less anti-slip, and moving the automobile tire on wet roads Increases the frictional resistance between the mat and the wet floor, similar to the action of This causes a less aggressive rubbing action on the mat pile during the washing process in the washing machine, which significantly reduces fraying. In addition, rubber molded pads are more easily made, and it is believed that they can be manufactured on simple rotary punches, rather than the costly vertical punches currently used. The resulting pad, due to the larger spacing between the anti-slip bodies,
It also has greater resistance to tearing. While the preferred embodiments of the invention have been particularly described, modifications may be made without departing from the scope of the invention, and the invention is desirably limited only by the claims.
