Abstract

A sports mat includes a foam sheet, an adhesive bonding film, a patterned layer and a skid proof layer. The foam sheet is made of polyethylene foam. The adhesive bonding film applied to a top surface of the foam sheet. The patterned layer has a plastic film and a pattern printed in a bottom surface of the plastic film. The plastic film together with the pattern is joined on top of the adhesive bonding film. The skid proof layer, made of thermal plastic rubber, is coated over a top surface of the plastic film. Additionally, the skid proof layer together with the patterned layer, the adhesive bonding film and the foam sheet defines a plurality of indentations and protrusions over a top surface of the skid proof layer so as to strengthen connection therebetween.

Claims (28)

1. A sports mat comprising:

a rollable foam sheet including a first foam layer and a second foam layer laminated to a top surface of said first foam layer, both of the first foam layer and the second foam layer made of polyethylene foam;

a plastic film provided on a top surface of said second foam layer ; and

a skid proof coating coated over a top surface of said plastic film and made of thermal plastic rubber.

2. The sports mat of claim 1 , wherein said first foam layer is formed therebottom with a plurality of elongated ridges parallel to one another.

3. The sports mat of claim 2 , wherein each of said elongated ridges of said first foam layer is arch-shaped in cross section.

4. The sports mat of claim 2 , wherein both of the first foam layer and the second foam layer contains an additive of elastic resin.

5. The sports mat of claim 1 further comprising a pattern provided on said top surface of said rollable foam sheet.

6. The sports mat of claim 5 , wherein said rollable foam sheet and said pattern form a contrast in color.

7. The sports mat of claim 1 further comprising a pattern provided on said top surface of said plastic film.

8. The sports mat of claim 7 , wherein said rollable foam sheet and said pattern form a contrast in color.

9. The sports mat of claim 1 further comprising a pattern provided on a bottom surface of said plastic film.

10. The sports mat of claim 9 , wherein said rollable foam sheet and said pattern form a contrast in color.

11. The sports mat of claim 1 , wherein both of the first foam layer and the second foam layer contains an additive of elastic resin.

12. The sports mat of claim 1 further comprising a pliable resilient embedment embedded in the rollable foam sheet; and wherein the pliable resilient embedment has a top face contacting with a bottom surface of the second foam layer and a bottom face contacting with the top surface of the first foam layer.

13. A sports mat comprising:

a rollable foam sheet including a first foam layer and a second foam layer laminated to a top surface of said first foam layer, both of the first foam. layer and the second foam layer made of polyethylene foam;

a pattern provided on a top surface of said second foam layer; and

a skid proof coating coated over said top surface of said second foam layer and made of thermal plastic rubber.

14. The sports mat of claim 13 , wherein said rollable foam sheet and said pattern form a contrast in color.

15. The sports mat of claim 13 , wherein said first foam layer is formed therebottom with a plurality of elongated ridges parallel to one another.

16. The sports mat of claim 15 , wherein each of said elongated ridges of said first foam layer is arch-shaped in cross section.

17. The sports mat of claim 15 , wherein both of the first foam layer and the second foam layer contains an additive of elastic resin.

18. The sports mat of claim 13 , wherein both of the first foam layer and the second foam layer contains an additive of elastic resin.

19. A laminated object, comprising:

a rollable foam sheet including a first foam layer and a second foam layer laminated to a top surface of said first foam layer, both of the first foam layer and the second foam layer made of polyethylene foam;

a pliable resilient embedment embedded in the rollable foam sheet, the pliable resilient embedment having a continuous top face contacting with a bottom surface of the second foam layer and a continuous bottom face contacting with the top surface of the first foam layer, wherein the pliable resilient embedment has a resilience sufficient to unroll the rollable foam sheet when the rollable foam sheet is rolled and untied; and

a cover coated over a top surface of the second foam layer and selected from the group of a skid proof coating and a laminated layer consisting of a plastic film on the top surface of the second foam layer and a skid proof coating on a top surface of the plastic film; wherein the skid proof coating is made of thermal plastic rubber.
