Abstract
Abstract There is provided a mat having multiple sets of pins, each set of pins being located within surrounding, characterized in that the pins do not extend significantly beyond the highest point of the surrounding. Thus the pins are protected by the surrounding and are less likely to break after extended use. The mat may be provided with areas adapted for the receipt of strips of textile materials, eg carpeting which advantageously has a hard-backing and is able to snap into the areas provided. The inclusion of the textile material combines a scraping function together with the visual appearance of a carpet. The strips of textile material will be separated by sets of pins as described above. A set of such mats is also described.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
104 words
A mat having: (a) multiple sets of pins, each set of pins being located within a surrounding; (b) a lower layer that is formed from a repeating array of shapes; (c) an upper layer that is formed from a repeating array of shapes; wherein the arrays of the upper and lower layers overlap and are not superimposed; and wherein the pins protrude from the upper surface of the lower layer and are located within a surrounding formed by the array of shapes of the upper layer and the height of the pins is at most no higher than the highest point of the surrounding.
Claim 2
Dependent Claim
104 words
A mat having: (a) multiple sets of pins, each set of pins being located within a surrounding; (b) a lower layer that is formed from a repeating array of shapes; (c) an upper layer that is formed from a repeating array of shapes; wherein the arrays of the upper and lower layers overlap and are not superimposed; and wherein the pins protrude from the upper surface of the lower layer and are located within a surrounding formed by the array of shapes of the upper layer and the height of the pins is at most no higher than the highest point of the surrounding.
Claim 3
Dependent Claim
29 words
A mat as claimed in claim 1 wherein the height of at least some of the pins is below the height of the surrounding for said pin or pins.
Claim 4
Dependent Claim
22 words
A mat as claimed in claim 1 wherein at least some of the pins are tapered or rounded at their free end.
Claim 5
Dependent Claim
19 words
A mat as claimed in claim 1 wherein the surrounding of a set of pins is ridged or castellated.
Claim 6
Dependent Claim
14 words
A mat as claimed in claim 1 having 6 to 8 pins per set.
Claim 7
Dependent Claim
42 words
A mat as claimed in claim 1 wherein the repeating arrays of the upper and lower layers are in a shape selected from the group consisting of circles, ovals, triangles, squares, rectangles, pentagons, hexagons, septagons, octagons, and a mixture of these shapes.
Claim 8
Dependent Claim
22 words
A mat as claimed in claim 6 , wherein the upper and lower arrays of repeating shapes are in the same shape.
Claim 9
Dependent Claim
25 words
A mat as claimed in claim 6 , wherein the repeating arrays of the upper and lower layers are in the shape of a circle.
Claim 10
Dependent Claim
52 words
A mat as claimed in claim 8 , further comprising linking members that span the spaces between the shapes of the arrays of the upper and lower layers, said linking members being located in the approximately square shaped motif formed by the junction of four circles of the upper and lower layers.
Claim 11
Dependent Claim
127 words
A mat having: (a) multiple sets of pins, each set of pins being located within a surrounding; (b) a lower layer that is formed from a repeating array of first shapes; (c) an upper layer that is formed from a second repeating array of shapes, the second repeating array of shapes comprising the first shapes and a second substantially rectangular shape; wherein the arrays of the upper and lower layers overlap such that the first shapes are not superimposed; and wherein the pins protrude from the upper surface of the lower layer and are located within a surrounding formed by the array of first shapes of the upper layer and the height of the pins is at most no higher than the highest point of the surrounding.
Claim 12
Dependent Claim
127 words
A mat having: (a) multiple sets of pins, each set of pins being located within a surrounding; (b) a lower layer that is formed from a repeating array of first shapes; (c) an upper layer that is formed from a second repeating array of shapes, the second repeating array of shapes comprising the first shapes and a second substantially rectangular shape; wherein the arrays of the upper and lower layers overlap such that the first shapes are not superimposed; and wherein the pins protrude from the upper surface of the lower layer and are located within a surrounding formed by the array of first shapes of the upper layer and the height of the pins is at most no higher than the highest point of the surrounding.
Claim 13
Dependent Claim
43 words
A mat as claimed in claim 10 , further comprising strips of textile material that are attached to the substantially rectangular shapes of the upper layer, said textile strips being the same shape as the second substantially rectangular shapes of the upper layer.
Claim 14
Dependent Claim
20 words
A mat as claimed in claim 10 , wherein said textile material is comprised of carpet having a hard backing.
Claim 15
Dependent Claim
27 words
A mat as claimed in claim 12 , wherein said textile strips are attached by snapping said textile strips into the rectangular shapes of the upper layer.
