Abstract

(57) [Summary] (Modified) [Purpose] To provide a tatami floor that is lightweight, has good resilience, insect repellency, and breathability, does not generate toxic gases due to fire, and does not harm the environment due to disposal. The purpose is to do. [Structure] A tatami floor with a palm mat 1 as a core and an insulation board 2 on both sides or one side thereof.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tatami floor that is lightweight, insect-proof, and that does not damage the environment by discarding it even if it emits toxic gas due to fire.

[0002]

[Prior Art]

 Tatami is a rug that is indispensable for Japanese-style rooms and has been used since ancient times. Traditionally, the core of tatami mats used for tatami mats has been mainly straw, but due to its heavy weight, easy insects, and hygroscopicity, the cores of tatami mats have recently been combined with expanded polystyrene and polystyrene. Synthetic resin materials and cork have been used as cores for tatami floors.

[0003]

[Problems to be solved by the device]

 The above-mentioned conventional tatami mats have drawbacks in that when straw is used, the weight and hygroscopicity are large, and insect repellent paper or the like is also used in order to avoid the generation of insects. Also, when using synthetic resin, the weight will be lighter, but since synthetic resin is used, it will be an industrial waste and the treatment after disposal will lead to environmental damage. Furthermore, fire, such as a fire, produces toxic gas, which has a considerable adverse effect on life. Cork has poor air permeability, and the problem of disposal is the same as that of tatami mats made of synthetic resin. The present invention aims to provide a tatami mat that solves these drawbacks.

[0004]

[Means for Solving the Problems]

 As a result of various studies to solve the above-mentioned problems, the present invention has less insects because palm mats, ie, mats of palm fibers, do not have hollow stems such as straw, and are lightweight and have good air permeability. Focusing on such advantages, we used palm mats as the core of tatami floors to solve the above-mentioned various problems. The present invention is a tatami floor with a palm mat as a core and an insulation board provided on both sides or one side thereof. The tatami floor is made by laminating natural fiber or synthetic fiber sheet on both sides or one side of the tatami floor. Furthermore, these tatami mats are made of coconut shell activated carbon.

A tatami mat according to claim 1 of the present invention will be described with reference to FIG. The tatami floor of the present invention has a structure in which a palm mat 1 and an insulation board 2 are provided on both sides or one side of the mat. In FIG. 1, an insulation board 2 is provided on both sides of a palm mat. The palm mat 1 of the present invention is formed by stacking palms, that is, coconut fibers into a mat shape, or by forming the non-woven mat into a mat shape from palm fibers by needle stick. The insulation board 2 is a material, such as wood, paper, or the like, in which fiber waste is hardened. The tatami floor of the present invention is made by laminating each of the above materials to about 50 to 55 mm. Whether the insulation board is provided on one side or both sides is appropriately selected depending on the purpose of use and location.

A tatami mat according to claim 2 of the present invention will be described with reference to FIG. The mat of the tatami core 1 and the insulation board 2 are made of the same material as in FIG. 1, and the structure of the insulation board provided on both sides or one side of the palm mat is the same. Further, a sheet 3 of natural fiber or synthetic fiber is provided on the surface of the insulation board 2 or the surface of the palm mat. In this case, a palm sheet or an abaca hemp sheet is preferably used as the natural fiber sheet.

In order to enhance the effects of deodorization, drying and the like on the tatami floor of the present invention, a palm is placed in the palm mat and / or between the palm mat and the insulation board or between the insulation board and the fiber sheet. Add shell activated carbon. The amount can be sufficiently achieved by using 200 g per one tatami-bed 17 Kg.

[0008]

[Effect of the device]

 Since the mat is used for the tatami floor of claim 2 of the present invention, it is lightweight and has resilience, and unlike so-called chemical floors that use synthetic resin, it produces toxic gas due to fire or the like. Since it is a natural fiber, there is no danger of destroying the environment as industrial waste because it does not have hollow stems like straw in its fiber structure, and it does not cause insects and has an insect repellent effect. Further, since it is a palm fiber mat, the air permeability is sufficiently maintained. In addition, the tatami floor of the present invention, in which the palm shell activated carbon is put, is extremely comfortable to use because it imparts deodorization and dryness to the palm shell activated carbon. As described above, the tatami floor of the present invention combines the advantages of the old straw floor, the recent chemical floor and the cork floor, and is a practically useful idea excluding these disadvantages.
