DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a walking surface protection mat which is laid on a corridor, stairs, a pedestrian bridge, a veranda, a poolside, a ground, or the like to protect indoor and outdoor walking surfaces.

[0002]

2. Description of the Related Art Waterproof foamed synthetic resin and non-foamed synthetic resin are used for indoor and outdoor walking surface protection mats. In particular, a foamed synthetic resin ground used indoors is called a cushion floor, and a non-foamed synthetic resin ground used indoors is called linoleum. Cushion floors and linoleum are formed by laminating a foamed or non-foamed synthetic resin composition thickly on a base cloth, and the surface thereof is embossed or printed with required makeup.

[0003]

In a cushion floor using a foamed synthetic resin composition, since the inside is an aggregate of a thin film of a synthetic resin surrounding air bubbles, the inside of the layer is apt to be peeled off on the front and back sides. When the expansion ratio is reduced to increase the inner peel strength, the linoleum, which is a non-foamed synthetic resin composition, has no cushioning property and has poor stepping comfort. On the other hand, increasing the foaming ratio in order to enhance the cushioning property not only lowers the peel strength within the layer, but also increases the ups and downs of the surface generated during walking, giving a pedestrian a feeling of fatigue. Since the cushion floor and the linoleum are both formed by thickly laminating the resin composition on the base cloth, they are heavy and difficult to carry, and the laying work is heavy labor.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention is bulky, has a large internal clearance, is light in weight as a whole, and is easy to carry. In addition, there is little change in floating and sinking of the surface during walking, and it does not give a pedestrian a feeling of fatigue and has a moderate cushioning property. It is intended to obtain a walking surface protection mat that is comfortable to step on.

[0005]

The walking surface protection mat 42 according to the present invention has gaps 11 and 12 between the internal fibers, and the ratio of the gaps 11 and 12 to the whole volume is 30% by volume or more. , Thick cloth with a thickness of 2 mm or more (17.2
7. 37), characterized in that the surface layer 14 of the resin composition 13 is laminated on the surface.
