Abstract

Examples of an exercise mat having a three-dimensional surface texture and methods for making same are disclosed. The exercise mat may have a first malleable layer formed from a polyurethane material with an elastic fabric material attached to a lower surface thereof. A second layer may be attached to the elastic fabric material of the first layer. The second layer may be formed from a thermoplastic elastomer material and may have the three-dimensional surface texture formed on an upper surface thereof to which the first layer conforms. The exercise mat may also include a third rubber layer attached to the second layer.

First claim

What is claimed is:

1. A method for making an exercise mat having a three-dimensional surface texture, comprising:
preparing a first layer of the exercise mat by pouring liquid polyurethane onto an elastic fabric and curing the polyurethane;
attaching a second layer that comprises a thermoplastic elastomer to a fabric side of the first layer, the fabric side being a lower surface of the first layer;
cutting a mat made from the first and second layers to a desired size and shape;
positioning the mat on a mold plate having an embossed top surface with a polyurethane side of the first layer facing the embossed top surface, the polyurethane side being an upper surface of the first layer, the embossed top surface being embossed with the three-dimensional surface texture;
inserting the mold plate into a vacuum embossing machine and heating the mat for 1 to 15 minutes at a temperature of 120 to 200 degrees Celsius; and,
cooling the mat for 5 minutes;
wherein the temperature and suction provided by the vacuum embossing machine softens the thermoplastic elastomer of the second layer conforming it to the three-dimensional surface texture of the embossed top surface of the mold plate; and,
wherein the first layer conforms to the three-dimensional surface texture of the second layer to thereby provide the three-dimensional surface texture on the upper surface of the first layer.

2. The method of claim 1 , further comprising attaching a third layer that comprises a rubber material to a lower surface of the second layer.

3. The method of claim 1 , wherein at least one edge portion of the exercise mat is contoured, beveled, or chamfered.

4. The method of claim 1 , wherein the three-dimensional surface texture is one or more of a ridged pattern, a water drop wave pattern, and a tidal flow wave pattern.

5. The method of claim 4 , wherein the exercise mat has a thickness of 5 mm and the three-dimensional surface texture extends from 0 to 3 mm below a top surface of the exercise mat.

6. The method of claim 2 , further comprising sandwiching a polyester cotton cloth material between the second layer and the third layer.

7. The method of claim 1 , wherein the elastic fabric is a four-way stretch nylon material.

8. The method of claim 1 , further comprising contouring, beveling, or chamfering at least one edge portion of the exercise mat whereby a thickness of the at least one edge portion gradually reduces from a greater thickness at a portion of the edge portion away from an edge of the exercise mat to a lesser thickness at the edge of the exercise mat.
