Description

  The present invention relates to a tile carpet.

Conventionally, a tile carpet laid on a floor surface is produced by arranging a large number of linear members made of bamboo or rattan in parallel on the surface of an elastic sheet (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 9-25705

However, bamboo or rattan, which is a natural material used in conventional tile carpets, is easily deformed with changes in humidity. For example, when dried, as shown in FIG. There was a drawback that it was raised and curved. When the tile carpet laid on the floor is curved, the floor is uneven, which is unsatisfactory in appearance and may cause a stumbling, and the tile carpet is easily peeled off from the floor.
Therefore, an object of the present invention is to provide a tile carpet that does not bend or warp.

In order to achieve the above object, a tile carpet according to the present invention comprises a surface material in which a large number of linear materials made of bamboo or rattan are arranged in parallel and densely, and a thin film adhered to the back surface of the surface material. Bamboo made of bamboo woven orthogonally as a fourth or netting knitted pattern on a square tile carpet with a sheet body and a non-woven fabric or other backing material laid corresponding to the floor surface Or the strain absorption layer which consists of many strip | belt-shaped members made from wood is interposed between the said thin sheet body and the said back surface material.
In addition, the overlapping portions of the above-mentioned many strip-shaped members were insufficiently bonded or non-bonded to each other.

The present invention has the following remarkable effects.
According to the tile carpet according to the present invention, it is possible to prevent the surface material from being curved in the strain absorbing layer.
That is, when the humidity of the tile carpet changes between a dry state and an overhumid state, the dimensions (such as length and width) of the natural linear material that forms the surface material change, and the surface material and the back material A relative internal stress is generated during this period, but the band-shaped member of the strain absorbing layer disperses and absorbs the internal stress. That is, it is possible to allow the belt-shaped members knitted perpendicularly to generate a minute shift from each other, and to disperse and absorb the internal stress. This can prevent the tile carpet from being bent or warped.

Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments.
In the first embodiment of the present invention, as shown in FIG. 1, a tile carpet 10 is formed in a square shape as a whole, and a large number of linear members 5 made of bamboo or rattan are arranged in parallel and densely. A surface material 1 is provided.
In FIG. 2, the tile carpet 10 includes a thin sheet body 6 bonded to the back surface of the surface material 1 and a back material 3 such as a nonwoven fabric laid corresponding to the floor surface F.
Further, a strain absorbing layer 2 is interposed between the thin sheet body 6 and the back material 3.

  As shown in FIG. 4 or FIG. 5, the strain absorbing layer 2 is formed into a plane by weaving a large number of bamboo or wooden strip members 4a, 4b, and the strip members 4a, 4b are mesh knitted. It is knitted perpendicularly. Further, the overlapping portions A of the belt-like members 4a and 4b are mutually insufficiently bonded or non-bonded. Here, the insufficient adhesion is defined as a state in which an adhesive adheres to and adheres to an area of less than 10% of the overlapping portion A of the belt-like members 4a and 4b that are orthogonal to each other. Under such an adhesive state of less than 10%, the overlapping belt-like members 4a and 4b are in a state where they can move slightly (adhere). In other words, the insufficient adhesion is an unintended adhesion due to the adhesive entering between the overlapping strip members 4a and 4b when the strain absorbing layer 2 is adhered to the thin sheet body 6 or the back material 3. The case where the band-like members 4a and 4b that are intentionally overlapped is firmly bonded is not included.

As a method for producing the tile carpet 10 of the present invention, as shown in FIG. 3, first, a large number of linear members 5 are bonded in parallel and densely to one surface (surface) of a square thin sheet body 6; The surface side intermediate member 7 is produced (see FIG. 4). Moreover, the upper surface of the linear material 5 is formed in a smooth convex curved surface, and the cross-sectional shape thereof is formed in a cupcake shape having a rectangular lower portion and a laterally bowed upper portion (see FIG. 2). . In addition, many linear materials 5 are not adhere | attached.
Next, in FIG. 4, the strain absorbing layer 2 prepared by knitting the belt-like members 4 a and 4 b in advance and the back surface material 3 are bonded together, and the surface side intermediate material 7 is formed on the surface side of the strain absorbing layer 2. Glue. In this way, the tile carpet 10 is manufactured. Moreover, as a raw material of the back surface material 3, it is the nonwoven fabric which consists of synthetic fibers, rubber | gum, or a soft plastic.
In addition, whichever order may be sufficient as the order which adhere | attaches the surface side intermediate material 7 and the back surface material 3 to the strain absorption layer 2. FIG.

  Further, since the strain absorbing layer 2 is formed by knitting the belt-like members 4a and 4b, both surfaces thereof are not flat but have irregularities. That is, as shown in FIG. 2, the strain absorbing layer 2 is partially bonded to the front surface side intermediate material 7 and the back surface material 3 (at the convex portion 15), and the front surface side intermediate material 7 and the back surface material 3 are strain absorbed. An air layer 8 exists between the recesses 16 of the layer 2.

When the strip-like members 4a and 4b of the strain absorbing layer 2 are made of bamboo, a manufacturing method thereof will be described. In FIG. 7A, the bamboo B is cut in the longitudinal direction along a virtual radial cutting line 12 drawn at a predetermined pitch in the circumferential direction to form a cut piece 9 having a predetermined length.
Next, as indicated by an imaginary line 13, both side ends, the front surface, and the back surface are cut off from the cut piece 9 to produce a strip piece 11 having a rectangular cross section shown in FIG.
Then, the strip member 11 is sliced in the longitudinal direction along the virtual cutting line 14 drawn in parallel to the long side of the transverse section of the strip member 11 to produce the strip member 4.
Moreover, the strip | belt-shaped member 4 is arrange | positioned by the fiber extending in the longitudinal direction.

Next, in the second embodiment of the present invention, as shown in FIGS. 1 and 2, a surface material 1 in which a large number of linear materials 5 made of bamboo or rattan are arranged in parallel and densely. And the thin sheet body 6 adhere | attached on the back surface of the surface material 1, and the back surface materials 3, such as a nonwoven fabric laid corresponding to the floor surface F, are provided. A strain absorbing layer 2 is interposed between the thin sheet body 6 and the back surface material 3.
As shown in FIG. 6, the strain absorbing layer 2 is formed in a plane by weaving a large number of bamboo or wooden strip members 4a, 4b, and the strip members 4a, 4b are four stitches. It is knitted perpendicular to the shape. Further, the overlapping portions A of the belt-like members 4a and 4b are mutually insufficiently bonded or non-bonded.

The use method (action) of the tile carpet of the present invention described above will be described.
As shown in FIG. 8, the tile carpet 10 of the present invention is laid on the floor F. Then, when the tile carpet 10 is placed in an environment where the humidity in the dry state and the excessive humidity changes, the natural material (bamboo or rattan) linear material 5 forming the surface material 1 in FIG. The dimensions (such as length and width) change, and a relative internal stress is generated between the front surface material 1 and the back surface material 3. At this time, in FIG. 2 or FIG. 5, the internal stress is dispersed and absorbed in the portion A where the strip-like members 4a and 4b overlap each other. That is, the belt-like members 4a and 4b knitted orthogonally are allowed to be slightly displaced from each other, and the internal stress is dispersed and absorbed.

As described above, the tile carpet of the present invention includes a surface material 1 in which a large number of bamboo or rattan linear materials 5 are arranged in parallel and densely, and a thin sheet bonded to the back surface of the surface material 1. 6 and bamboo which is knitted orthogonally as a fourth knitting shape or a net knitting shape in an overall square tile carpet provided with a back material 3 such as a nonwoven fabric laid corresponding to the floor F Since the strain absorbing layer 2 composed of a large number of strip members 4a and 4b made of wood or wood is interposed between the thin sheet body 6 and the back surface material 3, the surface material 1 is curved in the strain absorbing layer 2.
