PROBLEM TO BE SOLVED: To provide a carpet using a rush material with a high cushioning property.SOLUTION: A carpet 1 has a structure for which a laminate formed by laminating three cushion layers and two rush-mat layers on a base layer 101 that is a board-like material is covered with a rush-mat cover layer 109 and a side face not covered with the cover layer 109 is covered with another rush-mat side face cover part 110. On an end side not adjacent to another carpet 1 among four end sides of the carpet 1, an inclination to be lowered toward an outer side is provided. In order to realize such an inclination, an upper layer is set back to the inner side with respect to a lower layer of the laminate. Among the four end sides of the base layer 101, the end side to be adjacent to another carpet 1 is set back slightly to the inner side than the cushion layer of the upper layer. Thus, a gap is not easily generated between the carpets 1 adjacent to each other. Also, on a part where a direction of the inclination of the carpet 1 and a direction of rush fibers of the cover layer 109 become parallel, a non-skid member 111 is provided.

Description

  The present invention relates to a rug using rush grass.

  In recent years, an increasing number of houses have flooring rooms. While the flooring has conveniences such as easy cleaning, it is harder than a tatami mat, so it is painful and uncomfortable when sitting directly.

  Carpets and carpets have long been used as rugs on flooring. On the other hand, in recent years, flooring rooms with Japanese-style design have increased, and rugs using moss as a material have been used for flooring due to the fact that moss's ability to absorb harmful substances, moisture absorption and desorption is known. It is spreading as a rug.

  For example, Patent Document 1 proposes a rug using rush that has improved durability by covering the entire surface of the rush fiber with a transparent coating film.

[Embodiment]
Hereinafter, a rug 1 according to an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing nine rugs 1 in a state where they are arranged on a floor so as to form a square as a whole. In FIG. 1, nine rugs 1 are distinguished from each other by assigning branch numbers, such as rug 1-1 to rug 1-9.

  The overall shape of the rug 1 is classified into one of three types. That is, the rug 1-1, the rug 1-3, the rug 1-7, and the rug 1-9 provided in the corner, the first shape included in the rug 1-9, the rug 1-2 and the rug 1 arranged in the end sides that are not corners. -4, the rug 1-6, the second shape of the rug 1-8, or the third shape of the rug 1-5 disposed in the center.

  FIG. 2 is a view showing a first shape (FIG. 2A), a second shape (FIG. 2B), and a third shape (FIG. 2C) of the rug 1, respectively.

  The first-shaped rug 1 has a shape that is inclined so as to descend toward the end on two adjacent sides of the four sides of the square as viewed from above. In the first shape rug 1, the direction of the grass fibers of the cover layer 109 which is a ridge covering the upper surface is the one in the x direction of FIG. 2A (the rug 1-3, the rug 1-7), There are two types, one in the y direction (rug 1-1, rug 1-9).

  The rug 1 having the second shape has a shape that is inclined so as to descend toward one end of the four sides of the square as viewed from above. In the rug 1 of the second shape, the direction of the grass fibers of the cover layer 109 that is a ridge covering the upper surface is the one in the x direction of FIG. 2B (the rug 1-2, the rug 1-8), There are two types, those in the y direction (rugs 1-4, rugs 1-6).

  The rug 1 of the third shape is not provided with an inclination on any of the four sides of the square viewed from above.

  In order to provide the shape as described above, for example, when a plurality of rugs 1 are laid as shown in FIG. 1, the shape is inclined so as to descend in the direction indicated by the arrow in FIG. It becomes an inclined low hill-shaped rug. By tilting the edge in this way, the user does not go to the rug or feel a step when going up and down.

  FIG. 3 is a cross-sectional view of the rug 1 cut in the ZZ direction of FIG. As shown in FIG. 3, the rug 1 has a structure in which a laminate of a plurality of board-like or sheet-like materials is covered with a cover layer 109 as a whole.

  First, the rug 1 is provided with a base layer 101 which is a board-like material in the lowermost layer. The material of the base layer 101 is, for example, foamed resin, and the thickness thereof is, for example, about 1 centimeter. Among the four sides of the base layer 101, a cushion portion 102, which is an elastic sheet, is attached so as to cover the side with an inclination, that is, the side surface of the side located at the outer edge when arranged as shown in FIG. ing. The cushion part 102 is provided in order to reduce the impact when the user hits the base layer 101. The material of the cushion part 102 is, for example, felt, and the thickness thereof is, for example, about 5 millimeters.

  On the base layer 101, three cushion layers, that is, a cushion layer 103, a cushion layer 104, and a cushion layer 105 are laminated in that order from the bottom. The material of these cushion layers is, for example, urethane chip foam, and the thickness is, for example, about 1.5 centimeters. Of these three cushion layers, the cushion layer 104 disposed in the middle exhibits a higher elastic value than the cushion layer 103 and the cushion layer 105 disposed above and below the cushion layer 104. That is, the cushion layer 104 is softer than the cushion layer 103 and the cushion layer 105. Thus, by sandwiching the soft cushion layer 104 between the hard cushion layer 103 and the cushion layer 105, both the shape stability of the rug 1 and high cushioning properties can be obtained.

  On the cushion layer 105, two ridges, that is, ridges 106 and 107 are laminated. The direction of the grass fibers of the lower ridge 106 coincides with the direction of the grass fibers of the cover layer 109, and the direction of the grass fibers of the upper ridge 107 is orthogonal to the direction of the grass fibers of the cover layer 109. Are arranged as follows. In this way, the crossed moss fibers of birch are crossed so that a uniform and sufficient strength can be obtained in any direction along the plane of the rug 1.

  For example, in the edge provided with the inclination like the left edge of the rug 1-4 in FIG. 3, the edge of the upper layer recedes from the edge of the lower layer. For example, at the edge of the rug 1 provided with an inclination, the edge of the cushion layer 103 retreats by about 1 cm with respect to the edge of the base layer 101, and the cushion layer 104 is about 4 cm with respect to the cushion layer 103. Retreating, the cushion layer 105 is retracted about 4 cm with respect to the cushion layer 104. Thus, when it is comprised so that the edge may recede from a lower layer to an upper layer, when those laminated bodies are covered with the cover layer 109, the part can be inclined.

  Further, for example, at the edge where no inclination is provided, such as the edge on the right side of the rug 1-4 in FIG. 3, the edge of the base layer 101 recedes from the edge of the cushion layer 103 by about 5 millimeters. . Thus, since the end side of the base layer 101 is retracted from the cushion layer 103 or another cushion layer, a gap is hardly generated between the two rugs 1 arranged adjacent to each other. This is because the hard base layers 101 of the adjacent rugs 1 do not collide with each other.

  For example, as in the upper right portion of the rug 1-4 in FIG. 3, a corner perpendicular to the longitudinal direction is “L” so as to cover the corner at the upper corner of the edge where no inclination is provided. An edge protruding portion 108, which is a sheet-like member bent so as to show a letter shape, is disposed. FIG. 4 is a diagram showing the shape of the edge protruding portion 108. The material of the edge protruding portion 108 is, for example, paper, and may be a plurality of laminated thin papers or a single thick paper. The edge protruding portion 108 is arranged to firmly protrude the edge of the cover layer 109.

  The cover layer 109 faces the cushion layer 102, the cushion layer 103, the cushion layer 104, the cushion layer 105, the heel 106, the heel 107, and the edge protruding portion 108 from above from one side to the other side of the base layer 101 facing each other. It is a sheet-like body, and the material is cocoon. The two opposite sides of the cover layer 109 are each fixed to the base layer 101 with a body that has entered under the base layer 101. The other two sides not fixed to the base layer 101 are folded toward the inside of the rug 1.

  Therefore, the cover layer 109 does not cover a set of side surfaces of the rug 1 that face each other. The side surface that is not covered with the cover layer 109 is covered with a side surface cover portion 110 that is a sheet-like body independent of the cover layer 109. The side cover part 110 is a bag or cloth. When a cocoon is used as the side cover part 110, as shown in FIG. 5, the direction of the grass fiber of the side cover part 110 becomes a horizontal direction. Since the grass fibers of the side cover portion 110 are not vertical in this way, there is a risk that even if the user rests on the rug 1 and a vertical force is applied to the side cover portion 110, the grass grass fibers break and break. Less is.

  In the inclined region, for example, silicon resin slips on the surface of the cover layer 109 in a portion where the grass fiber direction of the cover layer 109 is parallel to the inclination direction, as shown in FIG. The stopper member 111 is applied by spraying or the like. This prevents the user from sliding along the direction of the grass fiber. Instead of application of a resin such as silicon resin, a configuration in which a cloth is attached to the surface of the cover layer 109 as the anti-slip member 111 by sticking or sewing may be employed.

  A plurality of holes are formed in the cover layer 109 at the edge where the rug 1 is not provided with an inclination, that is, the edge adjacent to the other rug 1, and the eyelet 112 is formed so as to protect the edges of the holes. It is attached. A string 113 is passed through the hole protected by the eyelet 112, as shown in FIG. The user can connect the adjacent rugs 1 by passing the string 113 through a hole protected by the eyelet 112 provided in each of the adjacent rugs 1 and tightening the string 113.

  According to the rug 1 having the above-described configuration, the shape of the rug 1 is selected so that the slope is arranged on the outer edge portion, and the rug 1 is laid on the floor so that the cushioning property of the grass material is placed on the floor such as flooring. A high rug can be placed, and a comfortable living space is realized even if you sit directly on it. At that time, since the outer edge portion is provided with an inclination, inconveniences such as the user crawling on the edge and feeling a step in the ascending and descending between the rug 1 and the floor are avoided. Moreover, since the anti-slip | skid member 111 is provided in the part in which the fiber direction of the grass which covers the surface of the rug 1 corresponds with the inclination direction of an inclination, a user does not slip along the direction of a grass fiber.

[Modification]
The embodiments described above can be variously modified within the scope of the technical idea of the present invention.

  The materials, numerical values, shapes, and the like in the description of the above-described embodiments are merely examples, and do not limit the present invention. For example, the shape of the rug 1 viewed from above is not limited to a square, and may be a rectangle, for example.

  Moreover, in the rug 1 described above, an internal structure in which two ridges are stacked on a three-layer cushion layer is employed. However, for example, the number of cushion layers and ridges is not limited thereto and can be arbitrarily changed. .

  In the rug 1 described above, a board-like material is used for the base layer 101, but a sheet-like material such as cloth may be used. Thereby, the rug 1 can be made a little thinner and lighter without impairing cushioning properties.

  Moreover, in the rug 1 described above, as a mechanism for connecting adjacent rugs 1, a structure in which a string 113 is tightened through a hole protected by an eyelet 112 is employed. For example, a belt or a snap button is used. For example, a coupling mechanism having another structure may be employed.

  Further, in the above description, the shape of the rug 1 when used in a state in which a plurality of sheets are spread is shown, but the rug according to the present invention may be used alone. In that case, as shown in FIG. 8, it is desirable to adopt a shape that is inclined so as to be lowered from the center toward the end portion in any direction.

  Further, the arrangement position and number of holes for connection shown in FIG. 7 can be variously changed. For example, when many holes are provided as shown in FIG. 9A, it is desirable that various designs can be obtained depending on how the strings are passed as shown in FIG. 9B.
