  Embodiments of the present invention will be described with reference to the drawings.

  (1) FIGS. 1 to 4 relate to a mat M as an example of an embodiment of the present invention.

  The mat M has a mat M main body and an edge body E coupled to the peripheral edge of the mat M main body, and has a rectangular shape in plan view. In addition, the planar view shape of the mat of the present invention is not limited to a rectangular shape, and may be, for example, various polygons including a square, a circle, an ellipse, and other shapes.

  The mat M main body has a large number of loop piles P planted on the base fabric B on the upper surface side of the base fabric B (the side positioned on the upper surface when the mat M is placed on a horizontal surface such as a floor surface). An elastomeric backing A made of a vulcanized rubber material is applied to the lower surface side of the original fabric portion S (tuft cloth) that is evenly provided.

  The edge body E is made of a polyvinyl chloride thermoplastic elastomer (polymer molding material), and the outer edge portion of the edge body E is located outward from the main body of the mat M. The inner part is fused to the periphery of the mat M body with the periphery sandwiched from above and below.

  The upper surface portion of the edge body E is inclined upward inward from the outer edge portion of the edge body E, and the height of the edge body E (the height of the highest position of the edge body E) is the mat M main body. Is approximately 1.2 times the height of the upper surface position (the height of the upper end position of the loop pile P).

  In the mat M, the upper portion of the edge body E and the peripheral edge portion of the mat M main body are welded together while the loop pile P on the upper surface side of the raw fabric portion S in the peripheral edge portion of the mat M main body is deformed. The polyvinyl chloride thermoplastic elastomer, which is a polymer molding material that penetrates into the upper portion and constitutes the upper edge portion of the edge E, is penetrated into the gap of the loop pile P on the upper surface side of the raw fabric portion S. ing. Since the height of the inner peripheral edge portion of the upper side portion of the edge body E is formed low, the loop pile P in that portion is compressed.

  Of the edge body E made of a polyvinyl chloride thermoplastic elastomer, the inner part from the inner and outer direction intermediate part is fused to the peripheral part of the mat M body with the peripheral part sandwiched from above and below, Bond strength and durability between the mat M main body and the edge E are high. However, the fusion between the upper side of the edge E and the peripheral edge of the mat M main body is such that the loop pile P on the upper surface side of the raw fabric S at the peripheral edge penetrates into the upper side of the edge E. Since the polyvinyl chloride-based thermoplastic elastomer constituting the upper edge portion of E is permeated into the gap of the loop pile P on the upper surface side of the original fabric portion S, the original fabric with respect to the upper edge portion of the edge E is obtained. Due to the anchor effect of the loop pile P on the upper surface side of the portion S, the bonding strength and durability between the mat M body and the edge body E are extremely effectively enhanced.

  (2) The mat L shown in FIG. 5 differs from the mat L shown in FIGS. 1 to 4 in that the edge F is fused to the upper side and the outer side of the peripheral edge of the mat L main body.

  In this case, since the edge F made of a polyvinyl chloride thermoplastic elastomer is fused to the upper and outer sides of the peripheral edge of the mat L main body, the bonding strength and durability between the mat L main body and the edge F are fused. Is expensive.

  Therefore, even when the mat L is used over a long period of time or under a heavy load, the separation of the edge F from the main body of the mat L and the peeling or cutting of the edge F are effectively prevented, and the durability is improved. Is expensive.

  The mat N main body is formed by applying a backing C made of a polyvinyl chloride thermoplastic elastomer on the lower surface side of the nonwoven fabric W as the raw fabric portion T. The fluffy surface portion of the nonwoven fabric W as the raw fabric portion T constitutes a pile.

  The edge G is made of a polyvinyl chloride-based thermoplastic elastomer (polymer molding material), and the outer edge of the edge G is positioned outward from the mat N main body. The inner portion is fused to the periphery of the mat N main body with the periphery sandwiched from above and below. The height of the inner peripheral edge portion of the edge G in the mat N is formed to be a groove shape, and the nonwoven fabric W in that portion is compressed.

  The upper surface portion of the rim body G is inclined upward from the outer edge portion of the rim body G inward, and the height of the rim body G is the height of the upper surface position of the mat N body (nonwoven fabric which is the raw fabric portion T) About 1.2 times the height of the upper surface position of W).

  In the mat N of this example, the non-woven fabric W on the upper surface side of the raw fabric portion T in the peripheral portion of the mat N main body is bonded to the peripheral portion of the mat N main body. The polyvinyl chloride thermoplastic elastomer, which is a polymer molding material constituting the upper edge portion of the edge G, penetrates into the gap between the nonwoven fabrics W on the upper surface side of the raw fabric portion T. Therefore, the bonding strength and durability between the mat N body and the edge G are extremely effective due to the anchor effect of the fibers constituting the nonwoven fabric W on the upper surface side of the raw fabric portion T with respect to the upper edge of the edge G. Be enhanced.

  (4) The pile in the raw fabric portion is not limited to the loop pile, but may be a cut pile, a velvet fluff, a nonwoven fluff-like surface portion, or the like. The raw fabric portion having a plurality of types of piles may be used.
