Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rug having a structure that can be directly placed on a floor surface or laid on a tatami mat, and has elasticity and rigidity against a load from the upper surface, which is highly breathable.

[0002]

2. Description of the Related Art Among rugs, there is known a thin tatami mat having a hem cloth as a surface covering layer of a straw mat fabric called a half tatami mat or a system tatami mat which is directly placed on the floor surface (for example,
JP-A-11-81632). This has the feature that a Japanese-style tatami space can be easily formed on a floor surface such as a Western-style room. In addition, JP-A-3-
There is also proposed a rug in which a sheet of warp bamboo weft woven by warp is laminated on a flexible sheet as disclosed in 81397 and JP-A-3-92181.

[0003]

[Patent Document 1] Japanese Unexamined Patent Publication No. 3-81397, Japanese Unexamined Patent Publication No. 3-92181, a rug on which a sheet of split bamboo weft is attached has an excellent feel to the sole of the foot, and
Although it has more breathable characteristics than the half-mat tatami mat of the surface covering layer tatami mat, it does not hold in the same state forever even if it moves when spread, or even if you arrange multiple sheets and spread them. There are difficulties. In addition, there is a problem that the end portion is turned when walking. Therefore, we examined the provision of a rug with a new structure that is stable when placed directly on the floor, as is called a half-mat tatami mat or system tatami mat, but has excellent elasticity, breathability, and touch.

[Means for Solving the Problems] As a result of studying the above problems, as a result, a covering surface layer of a surface made of bamboo or rattan weft with warp, a board layer for maintaining the rigidity of the entire rug, and the board. The rug comprises a cushion layer between the layer and the covering surface layer, and a back surface coating layer with anti-slip projections on the back surface of the board layer. The bamboo and rattan wefts are preferably formed to have a diameter of 3 mm or more and 15 mm or less, and the edge is preferably finished with an edge cloth.

[0005] Further, a surface layer of a surface of a bamboo or rattan weft formed into a sheet of warp formed into a diameter of 3 mm or more and 15 mm or less, an internal board layer for maintaining the rigidity of the entire rug, and the board layer And a cushion layer between the coated surface layers, a cushioning sheet provided on the backside of the board layer, the backside covering layer with the anti-slip projections on the backside of the cushioning sheet, and an edge cloth.

The plant-made weft has a flat cross section consisting of a short diameter and a long diameter, and in the case of bamboo, the long diameter (abbreviated as diameter in the present invention) is preferably about 5 mm. If the diameter is less than 3 mm, it is woven, but the surface rigidity is inferior, and the feel is the same as that of existing tatami mats. If the diameter is 15 mm or more, the surface rigidity becomes too high and hard, and the elasticity is lost, which is not preferable as a rug.

The inner board layer that maintains the rigidity of the entire rug is a wood board, that is, an insulation board obtained by defibrating a wood material into a pulp, impregnating a binder resin into the wood board, and press-molding the resin. , Wood fiberboard or chipboard wood-based particle board hardened with a binder, intermediate hardboards between these, plywood with thinly peeled wood laminated alternately in the vertical and horizontal directions, or palm shell board, etc. . A particle board or a palm shell board is particularly preferable in order to give an appropriate weight and surface rigidity.

A thin cushion layer of about 2 to 7 mm is provided between the board layer and the covering surface layer. As the cushion layer, a synthetic resin foam having high elasticity such as polyurethane or polyethylene is preferable. Due to the presence of this cushion layer, the feel of the rug surface is soft even if the intermediate board layer is hard.

The back surface of the board layer is provided with a coating layer having anti-slip projections. The backside coating layer is preferably a non-woven fabric in consideration of low cost, strength, adhesion to the board layer, and the like, and a woven fabric, a synthetic resin sheet, or the like can also be used. Cellulose-based or polyolefin-based nonwoven fabrics are most preferable because they are easily disposed of. The non-slip protrusions on the back are natural rubber,
Among synthetic rubbers, those exhibiting good slip resistance are used to form spots or lattices.

The back surface of the board layer is also provided with appropriate elasticity and reinforcement properties to prevent unsteadiness when directly placed on the floor, prevent squeak noise, improve durability, prevent scratches on the floor, etc. Therefore, it is preferable to arrange a buffer sheet. It is preferable to use cardboard as the cushioning sheet because it is inexpensive and easy to dispose of.

The rug of the present invention is made of a constituent material in consideration of safety of human bodies and pets, ease of disposal, global environmental protection, etc., without using chemicals as an anti-mite / antifungal agent,
Naturally obtained pine resin was retained inside as an anti-tick and anti-mold agent. Although the pine resin may hold the powder inside, in order to prevent the powder from being dispersed, it is possible to melt the pine resin by applying it to the internal components by melting and melting it at about 80 ° C. For example, it is dissolved in turpentine oil or an aromatic organic solvent and applied on the surface or the inner surface.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below with reference to the drawings. FIG. 1 is a partially cutaway perspective view of the rug of the present invention, and FIG. 2 is a sectional view taken along line AA in FIG. As seen in these figures, the surface layer 1 of the surface is made by weaving a weft thread 2 of a bamboo string having a flat cross section having a short diameter and a long diameter with a warp 3 in a sheet shape. The bamboo cross weft strip 2 having a flat cross section has a major axis of 5 mm and a minor axis of about 1 mm. It is the internal particle board layer 4 that retains the surface rigidity and appropriate weight of the entire rug, which is 10 mm thick. A cushion layer 5 is provided between the board layer 4 and the covering surface layer 1 on the surface. As the cushion layer 5, a polyurethane foam sheet having a thickness of 5 mm is sandwiched between the board layer 4 and the covering surface layer 1 on the surface. As a result, when a person walks on the rug, a soft feeling can be obtained even though bamboo is used on the surface and particleboard is used inside.

In order to provide the back surface of the board layer 4 with appropriate elasticity and reinforcement, a cushioning sheet 6 is arranged in this example. Cardboard is used for the cushioning sheet because it is cheap and easy to dispose of. The back surface of the rug of the present invention is a back surface coating layer 7, and the non-woven fabric back surface coating layer 7 is provided with anti-slip projections 8 of synthetic rubber in spots so as to exhibit slip resistance.

The edge cloth 9 provided on both edges of the rug of the present invention is
What is sewn on the covering surface layer 1 on the surface is folded back, and is turned from the edge portion to the buffer sheet 6 side for adhesion. A back surface coating layer 7 of a non-woven fabric is stuck on the top of the surface to finish. A liquid prepared by dissolving pine resin in turpentine oil was sprayed on the surface side of the rug thus finished as an anti-mite / antifungal agent.
The standard product shape is 100 cm in length x 100 cm in width, and can be finished in the same manner as a regular tatami mat. The place of division and the number of divisions are arbitrary. For 3 tatami mats, 3 tatami mats, 2 tatami mats for 2 tatami mats, 1 tatami mat for half tatami mats, and in the case of approximately half tatami mats, for example, about 2 tatami mats.
