Abstract

Entrance matting includes a flexible base layer (12) and a flexible upper layer (14) comprising spaced, upstanding strips (16) and defining slots (18) therebetween. Strips of carpet and the like (20) are fixed in the slots (18). The matting is located on a floor at a building entrance with the strips (16, 20) perpendicular to the direction of traffic over the matting for use in scraping dirt and taking moisture from the feet of people entering the building.

Claims

1. Matting including:

a flexible base layer;

a flexible upper layer comprising spaced, upstanding strips and defining upper scraper surfaces with continuous slots therebetween defined between sidewalls of adjacent strips; and

strips of carpet located in and extending along the slots to define, together with said upper scraper surfaces, a substantially planar upper matting surface, said carpet strips fitting snugly between said sidewalls to substantially fill said slots.

2. The matting of claim 1, wherein the base layer and the upper layer are integral.

3. The matting of claim 1, wherein the base layer and the upper layer are formed of a material selected from rubber or soft PVC.

4. The matting of claim 1, wherein the upper surfaces of the upstanding strips are ribbed.

5. The matting of claim 1, wherein the base layer and upper layer are in the form of a relatively large area integral slab.

6. The matting of claim 1, wherein the strips of carpet are releasably secured in the slots.

7. The matting of claim 1, wherein the underside of the base layer defines a plurality of longitudinal flutes to allow for ventilation between the matting and a supporting substrate.

13. Matting as recited in claim 1, wherein said strips of carpet are secured within said slots by an adhesive.

14. Matting as recited in claim 1, wherein there are a plurality of ribbed scraper surfaces formed on said upstanding strips to define said upper scraper surfaces.

8. A method of producing matting comprising the steps of:

extruding a slab of flexible substrate including a base layer and an upper layer;

forming the upper layer to define spaced strips defining upper scraper surfaces with continuous slots therebetween defined between sidewalls of adjacent strips;

providing strips of carpet; and

adhering the strips of carpet in the slots to lie along the slots and sizing said strips such that they fit snugly between said sidewalls.

9. The method of claim 8, wherein the spaced strips and slots of the upper layer are formed as the substrate is extruded.

15. A method as recited in claim 8, wherein said strips of carpet are adhered in said slots by an adhesive.

16. A method as recited in claim 8, wherein said upper scraper surfaces are defined by forming a plurality of ribs on said spaced strips.

10. Entrance matting including:

a flexible base layer;

a flexible upper layer comprising spaced, upstanding strips and defining a plurality of ribbed scraper surfaces with continuous slots therebetween, the base layer and the upper layer being integral and formed of a material selected from rubber or soft PVC; and

lengths of carpet located in and extending along the slots such that the carpet and the scraper surfaces collectively define a substantially planar upper matting surface.

11. Entrance matting as recited in claim 10, wherein said slots are defined between adjacent sidewalls of said upstanding strips, and said lengths of carpet fit snugly between said adjacent sidewalls to substantially fill said slots.

12. Entrance matting as recited in claim 10, wherein said lengths of carpet are formed as strips that are connected to said slots by an adhesive.
