JPH05337072A - Dust control mat of improved antislip body - Google Patents

Abstract

PURPOSE: To provide a dust control mat lined with an arrangement of a new and improved antislip body. CONSTITUTION: This is a dust control mat 10 of more than one row of an ellipsoidal antislip body 22 arranged with an angle to a hem 24 of the mat. An antislip body of each row is parallel to the other antislip bodies in the same row, and is practically perpendicular to that of an adjacent row. A second pattern of a small round antislip body 23 is located between the ellipsoidal antislip bodies 22 in each row, and that at regular intervals.

Description

Detailed Description of the Invention

[0001]

FIELD 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 rubber or a rubber-like material on the other side. This type of mat is commonly used in aisles where people tend to dust or scrape their feet to prevent carrying moisture and / or dust on footwear to other areas of the building. It Usually, these mats are installed in a high traffic area such as a doorway.

[0002]

In recent years, dust control mats such as those disclosed in U.S. Pat. No. 4,761,065 have been developed to prevent movement of the mat when installed on a surface to be protected.
The bottom surface is molded with an anti-slip body. Various types of anti-skid shapes and arrangements have been used that provide anti-migration properties, but there have also been problems associated therewith.
Most of the included anti-skid bodies are very small, and many of these anti-skid bodies have a constant spacing across the back surface of the mat. The molding pad used to form the pattern is difficult and costly to manufacture due to the many holes in the pad required to extrude the rubber therethrough to form an anti-slip body during vulcanization. This has caused problems in molding, as it is subject to tearing and shortens the service life. Furthermore, the dust control mat, which has a large number of small anti-skid bodies on its back side, caused an excessive amount 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 on its back surface a new and improved anti-skid body arrangement. Other objects and advantages of the present invention will be readily apparent as the present invention is described with reference to the drawings.

EXAMPLE In the preferred embodiment of the invention, mat 10
Comprises a pile yarn 14 of nylon, cotton, polyester, etc. tufted through a knitted or non-woven substrate 16 of suitable material, the bottom 18 of the tufts being provided with a rubber or rubbery backing 20 during vulcanization. It is glued. A large number of anti-slip bodies 22 and 23 are integrally molded or fixed to the bottom of the backing 20. Each mat typically has an edge 24 around it.

The anti-slip body 22 has an elliptical shape 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 present invention, the floor or surface that engages the surface of the anti-skid body is roughened or textured to increase its frictional resistance.

As shown in FIG. 2, all anti-skid bodies in any one row are parallel to each other and substantially at right angles to the anti-skid bodies 22 in the adjacent row. Preferably, the long axis of each anti-skid is about 45 relative to the edging 24.
Make an angle of °. It can be seen that the anti-skid body 22 has about two anti-skid bodies per 4 square inches of the back surface of the mat, and has a wide space between the other anti-slip bodies.

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

The anti-skid array described above provides firm floor mobility, much like that of the flat backside design, but significantly better than the small anti-skid bodies widely used in modern dust control mats. Has mobility. In addition to improved mobility, the new anti-skid pattern provides a larger size of anti-skid body, requires substantially less anti-skid body, and reduces the movement of automobile tires 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. Moreover, it is believed that rubber molded pads are easier to make and that they can be manufactured on a simple rotary punching machine, rather than the costly vertical punching methods currently in use. 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 are possible without departing from the scope of the invention and it is desirable that the invention be limited only by the claims.
