Modes for Carrying Out the Invention

[0013] Hereinafter, the best mode for carrying out the invention will be described in detail with reference to the accompanying drawings.

[0014] (Embodiment 1) FIG. 1 is a plan view showing the floor material 100 of Embodiment 1 of the present invention. FIGS. 2 and 3 are reference views showing the usage state of the floor material 100 of Embodiment 1 of the present invention. As shown in FIG. 1, the floor material 100 of Embodiment 1 of the present invention is formed by fitting a plurality of foamed rubber pieces 2a into a base material 1 made of a soft urethane resin or a polyurethane resin at intervals in the plane direction of the base material, and has a square sheet shape. The base material 1 is made of a sponge such as chip urethane. Among sponge materials, a relatively hard material is used for the base material 1. It is desirable to use a sponge material with a hardness of 120 N or more as measured in accordance with Method A specified in JIS6400-2 (2012 edition) for the base material 1.

[0015] The foamed rubber pieces 2a of the floor material 100 of Embodiment 1 are made of foamed rubber of a nitrile rubber (NBR sponge) material having oil resistance, abrasion resistance, and aging resistance, and are formed or cut into a size of 5 millimeters or more and 25 millimeters or less in diameter. The shape of the foamed rubber piece 2a may be a cube or a rectangular parallelepiped, or a piece cut into a spherical shape, an elliptical shape, or a random shape. Further, it is preferable to use the foamed rubber piece 2a having a hardness of 5 degrees or more and 40 degrees or less as measured by a type A durometer such as a shore hardness tester A, and it is most optimal to use the one having a hardness of 20 degrees or more and 35 degrees or less.

[0016] When embedding the foamed rubber pieces 2a into the base material 1, it is desirable to embed them so that the gap between the foamed rubber pieces 2a is 2 cm or more and 15 cm or less. Regarding the method of embedding into the base material 1, it is also possible to make incisions in the base material 1 at intervals of 2 cm or more and 15 cm or less, and fit the foamed rubber pieces 2a into the incisions, or to provide holes at intervals of 2 cm or more and 15 cm or less and embed the foamed rubber pieces 2a into the holes. In this way, the floor material 100 completed by embedding the foamed rubber pieces 2a into the base material 1 can be laid by connecting and laying a plurality of them, and can be laid on floors of any size. Also, since the floor material 100 can be easily cut with scissors or a cutter, it can be laid without gaps on the floors of rooms of any shape. Each sheet of the floor material 100 is lightweight, easy to transport, and does not require labor for construction. Since the floor material 100 is soft, it conforms to the unevenness of the floor base, and unlike the conventional method, it does not require applying an adhesive to the floor base and the construction is easy.

[0017] As shown in FIG. 2, the floor material 100 is laid on the floor and used directly thereon for standing, sitting, training, etc. The floor material 100 is soft and elastic, and since the embedded foamed rubber pieces 2a are exposed on the surface, when standing with the sole of the foot in contact with it, the function of the foamed rubber material aligns the trunk and improves the sense of balance of the whole body. When training is performed on the floor material 100, the trunk is less likely to wobble and it becomes easier to brace the feet, so the efficiency of training can be dramatically improved.

[0018] Also, as shown in FIG. 3, the floor material 100 may be laid under the floor. After laying the floor material 100 throughout the room, when a floor board Y such as a flooring board or a vinyl cloth is constructed thereon, it functions as a cushioning material under the floor board Y, and the feeling under the sole when stepping on the floor board Y becomes very soft. When the floor material 100 is laid under the floor and the floor board Y is laid thereon, and when standing, sitting, or living a normal life, the impact when lowering the foot to the floor is alleviated, the feeling felt on the sole becomes soft, the trunk of the body is less likely to sway, and the overall sense of balance of the body can be improved. Even without performing strenuous training, simply laying it under the floor and walking on it can achieve a healthy body balance.

[0019] The floor material 100 of Embodiment 1 is in the shape of a square sheet, but the floor material 100 may have various shapes other than a square, for example, a rectangular shape, a circular shape, an elliptical shape, a polygonal shape, etc.

[0020] (Actual Embodiment 2) Next, while showing FIGS. 4 to 6, the floor material 200 of Embodiment 2 of the present invention will be described. FIG. 4 is a plan view showing the floor material 200 of Embodiment 2 of the present invention. FIGS. 5 and 6 are reference views showing the usage state of the floor material 200 of Embodiment 2 of the present invention.

[0021] The floor material 200 of Embodiment 2 of the present invention is a square sheet made of an EVA material, in which a plurality of foamed rubber columns 2b, which are column-shaped members made of foamed rubber, are embedded at intervals in the surface direction of the base material. The EVA material has a certain degree of hardness, but has a soft touch and elasticity when touched, and is an optimal material as a floor material. Holes are made in the sheet made of the EVA material at predetermined intervals, and the foamed rubber columns 2b of appropriate sizes are fitted into the holes to form the floor material 200. For the foam rubber used in the foam rubber columns 2b of the floor material 200 in Embodiment 2, it is desirable to use a nitrile rubber (NBR sponge) material with oil resistance, abrasion resistance, and aging resistance. Also, for the foam rubber columns 2, it is advisable to use those with a hardness measured by a Type A durometer such as a Shore hardness tester A of 5 degrees or more and 40 degrees or less, and those with a hardness of 20 degrees or more and 35 degrees or less are optimal.

[0022] As shown in FIG. 4, the foam rubber columns 2b embedded in the base material 1 are cylindrical with a diameter of 5 millimeters or more and 25 millimeters or less. Column shapes other than cylindrical are also acceptable. It is desirable to have a shape that fits the holes provided in the base material 1. When embedding the foam rubber columns 2b in the base material 1, it is desirable that the gaps between the foam rubber columns 2b are embedded so as to be 2 centimeters or more and 15 centimeters or less. Regarding the method of embedding in the base material 1, holes are provided in the base material 1 at intervals of 2 centimeters or more and 15 centimeters or less, and the foam rubber columns 2b are fitted into the holes. In this way, the floor material 200 completed by embedding the foam rubber columns 2b in the base material 1 can be laid by connecting and laying a plurality of them, and can be laid on floors of any size. Also, the floor material 200 can be cut with a cutter or the like and laid according to the shape of the floor of the room. Since the floor material 200 is soft, it conforms to the unevenness of the floor base, eliminating the need to apply an adhesive to the floor base as in the past and making the construction easy.

[0023] As shown in FIG. 5, the floor material 200 is laid on the floor and used directly for standing, sitting, training, etc. on it. The floor material 200 has elasticity, and since the embedded foam rubber columns 2b are exposed on the surface, when standing with the soles of the feet in contact with it, the function of the foam rubber material aligns the trunk and improves the overall body balance sense. When training on the floor material 200, the trunk is less likely to wobble and it is easier to brace the feet, so the training efficiency can be dramatically improved.

[0024] Also, as shown in Fig. 6, the flooring material 200 may be laid under the floor. After covering the entire room with the flooring material 200, when a floor board Y such as a flooring board or a vinyl cloth is installed on top of it, the flooring material 200 functions as a cushioning material under the floor board Y, making the feeling under the soles of the feet softer when stepping on the floor board Y. When the flooring material 200 is laid under the floor board Y and one stands, sits, or conducts normal daily activities on it, the impact when lowering the feet to the floor is alleviated, the feeling felt on the soles of the feet becomes softer, the torso is less likely to wobble, and the overall sense of balance of the body can be improved. One can obtain a healthy body balance simply by laying it under the floor and walking on it without engaging in strenuous training.

[0025] (Embodiment 3) Next, while showing Figs. 7 to 10, the flooring material 300 of Embodiment 3 of the present invention will be described. Fig. 7 is a plan view showing the flooring material 300 of Embodiment 3 of the present invention. Fig. 8 is an enlarged reference view of part A of the flooring material 300 in Fig. 7. Figs. 9 and 10 are reference views showing the usage state of the flooring material 300 of Embodiment 3 of the present invention.

[0026] As shown in Figs. 7 and 8, when manufacturing the base material 1 of the flooring material 300 of Embodiment 3 of the present invention, which is made of a soft urethane resin or a polyurethane resin, finely crushed foam rubber pieces 2c are mixed in, and the flooring material 300 is formed in a state where the foam rubber pieces 2c are mixed in the base material 1. It is desirable to use a nitrile rubber (NBR sponge) material with oil resistance, abrasion resistance, and aging resistance for the foam rubber pieces 2c mixed in the base material 1 of the flooring material 300 of Embodiment 3. For the foam rubber pieces 2c, it is preferable to use those with a hardness measured by a type A durometer such as a Shore hardness tester A of 5 degrees or more and 40 degrees or less, and those with a hardness of 20 degrees or more and 35 degrees or less are optimal. As shown in Fig. 8, the foam rubber pieces 2c embedded in the base material 1 are pieces with a diameter of 2 millimeters or more and 25 millimeters or less. The foam rubber pieces 2c and the urethane resin or the polyurethane resin are sufficiently stirred, and the flooring material 300 is formed so that the foam rubber pieces 2c are distributed substantially evenly in the base material 1. The amount of the foam rubber pieces 2c is desirably 0.03 times to 0.1 times the amount of the urethane resin or the polyurethane resin of the base material 1.

[0027] The floor material 300 completed in the above process is made into a size and shape that matches the floor of the room, and can be laid on the floor, formed into mats of square, rectangular or other shapes, and multiple mats can be connected and laid on the floor for construction. As shown in Fig. 10, the floor material 300 is laid on the floor and used directly thereon, such as standing, sitting, or training. Since the floor material 300 is elastic and has a soft touch when contacting the skin, when standing with the sole of the foot in contact with it, the function of the foamed rubber material can straighten the trunk and improve the balance sense of the whole body. When training is carried out on the floor material 300, the trunk is not easily shaken and it is easier to brace the feet, so the training efficiency can be improved dramatically.

[0028] Also, as shown in Fig. 11, the floor material 300 may be laid under the floor. After covering the room with the floor material 300, when a floor board Y such as a flooring board or a vinyl cloth is constructed thereon, it functions as a cushioning material under the floor board Y, and the touch of the sole of the foot when stepping on the floor board Y becomes soft. When the floor material 300 is laid under the floor board Y and standing, sitting, or living a normal life on the floor board Y, the impact when lowering the foot to the floor is alleviated, the touch felt on the sole of the foot becomes soft, the trunk is not easily shaken, and the balance sense of the whole body can be improved. Even without performing strenuous training, simply laying it under the floor and walking on it in daily life can achieve a healthy body balance.

[0029] In the embodiment of the present invention, an embodiment of using it as a floor material has been described. However, the floor material of the present invention may be cut into a predetermined size and used as a cushion or a mat.
