Description

Improved tatami

This creation is related to tatami, and more specifically to a tatami-resistant person who is resistant to water, dirt, durability and light weight.

According to the traditional tatami mat, the bottom of the mat is composed of a mat and a mat. The bottom of the mat is generally compressed in a straw shape and has a rectangular plate shape. The mat is woven with natural materials such as valerian or other plant fibers. On the outside of the bottom of the mat, the composition of the material can be used to obtain the feeling of lying in the warm winter and cool in summer.

Although tatami has a lie-like feeling of warm winter and cool summer, the shape of the rectangular sheet is not small, and it cannot be folded, and the weight is not light. Therefore, the handling and assembling process is inconvenient, and if accidentally Tea, water, beverages and children's bedwetting, the water will be absorbed by the bottom of the straw and the bottom of the mat will be damp. If it is not treated in time (the material relationship can not be washed), it will be mildewed and smelly. Even if the above situation does not occur, the tatami will absorb moisture when used for a long time. However, due to the restrictions of the living environment, not all households can move the tatami to the outdoors.

Because the tatami has the above-mentioned shortcomings, less and less people are buying tatami to use it. In order to solve the above-mentioned tatami, the tatami will absorb water. The shortcomings of mold and overall weight are the development of a tatami mat that replaces the bottom of the straw with a foamed material, such as the Republic of China No. 354104 "Tatami Improvement" and No. 439820 "Tatami Structure Improvement". As shown, the tatami can make the tatami overall lighter in weight, easy to handle and splicing, and does not mold due to water absorption.

Although the previously disclosed patent can solve the shortcomings of the conventional tatami, the hardness of the foamed material as the bottom of the mat is too soft to maintain the rectangular shape of the tatami, and if the hardness is too high, the lying feeling will be reversed. The tatami made of straw is still worse than the bottom, and there is obviously still improvement.

The main purpose of this creation is to provide a tatami that can solve the problem of lack of overall weight, which can reduce the load during handling and assembly, and can meet the needs of maintaining shape stability and lying comfort. Water-resistant, dirt-resistant and durable, and of practical value.

In order to achieve the foregoing objectives, the present invention provides an improved tatami comprising an elastomer, made of a closed foam material, comprising an intermediate layer and an outer layer on both sides of the intermediate layer, the intermediate layer and the second layer. The hardness of the outer layer is different; and a straw surface covers the outer side of the elastomer.

Further, the hardness of the intermediate layer is higher than that of the two outer layers.

Further, the hardness of the intermediate layer is 70-75 degrees, and the hardness of the two outer layers is 45-50 degrees.

Further, the mat surface is sewn to the elastic body by using a suture Outside.

Further, the mat surface is coated on the peripheral side and the top side of the elastic body, and then sewn by a suture.

Further, the utility model further comprises a second protective edge, which is a soft sheet, which is coated on opposite sides of the elastic body and is sewn to the outside of the elastic body by a suture.

Further, the two ends of the two retaining edges are extended, the mating surface is covered, and the elastic body and the grass mat surface are sewn together.

The first figure is a partial perspective view of a preferred embodiment of the present invention.

The second drawing is a partial cross-sectional view of a preferred embodiment of the present invention.

The third drawing is a partial perspective view of another preferred embodiment of the present invention.

The fourth drawing is a partial cross-sectional view of another preferred embodiment of the present invention.

In the following, a preferred embodiment of the present invention will be described in detail with reference to the drawings. First, please refer to the first and second figures. The tatami 10 of the preferred embodiment of the present invention includes There is an elastomer 12 and a grass mat 14 .

The elastic body 12 is made of a closed EVA foam material, and has a three-layer rectangular block shape, such as a sandwich, comprising an intermediate layer 22 and two outer layers 24, 26 on both sides of the intermediate layer 22, and the intermediate layer 22 The hardness is 70-75 degrees, which is higher than the hardness of the two outer layers 24, 26 by 45-50 degrees. Of course, each of the intermediate layers 22, The outer layers 24, 26 are not limited to the aforementioned hardness and may be adjusted as needed.

The mat surface 14 is a rectangular surface which is woven by a natural material such as valerian or other plant fibers in a tatami mat, and is formed in a rectangular sheet shape, covering the top and rear ends of the elastic body 12 and extending and covering the elastic body. From 12 to the bottom side, the mat surface 14 is sewn to the elastomer 12 using one or more stitches 28.

In addition, the second protective cover 16 is further provided with a soft sheet such as a cloth, which is coated on the two sides and the two ends of the elastic body 12 and extends to cover the mat surface 14 and utilizes one or several stitches 29 . The two retaining edges 16 are sewn to the surface of the elastic body 12 and the mat surface 14.

Therefore, the characteristics and functions of the tatami 10 are as follows: the tatami 10 is the sole of the three-layer structure of the elastic body 12, which is different from the tatami mat made of straw, and is lighter in weight and can be lightened. The load during transportation and assembly work, and the elastic body 12 does not absorb water, and has water-resistance and anti-dirty effects, and can improve the moldiness of the tatami mat, which is caused by water absorption, and is difficult to clean, and is more durable.

Secondly, the hardness of the intermediate layer 22 of the elastomer 12 is higher than that of the two outer layers 24, 26. Therefore, not only can the overall structure of the tatami 10 have a certain strength by the intermediate layer 22, but it is not bent or deformed by external pressure. The stability of the tatami 10 shape is maintained, and the hardness of the two outer layers 24, 26 is softer than that of the intermediate layer 22, and is softer than the tatami straw bottom, which can meet the requirements of maintaining shape stability and lying comfort.

Furthermore, the mat of the tatami 10---the grass mat 14 is tied with 蔺 The weaving of natural materials such as grass weaving or plant fiber and paper fiber is like traditional tatami. Therefore, the overall appearance not only completely simulates the traditional tatami, but also has the functions of traditional tatami, such as water resistance, dirt resistance and durability. Sex. Of course, the use of the mat 14 will inevitably be damaged. If the elastic body 12 is not damaged, the tatami 10 can be returned to the manufacturer's updated mat 14 for reuse. The elastomer 12 is really unrepeatable and can be recycled and reused after being discarded. In other words, the components of the tatami 10 can be recycled or remanufactured, which can be said to be all environmentally friendly products!

As shown in the third and fourth figures, the tatami 30 of another preferred embodiment of the present invention is substantially the same as the tatami 10 except that the mate surface 32 is completely covered with the elastomer. 34 outside. Thereby, the tatami 30 can also achieve the aforementioned effects.

It must be mentioned that the hardness of the outer layer of the elastic body can also be set differently, so that the user can select the lying surface of the tatami according to his own needs, and the elasticity is better.

In summary, the tatami provided by the creation is composed of three layers of rectangular block-shaped elastic body and grass mat surface, which not only has a light overall weight, but also reduces the load during handling and assembling, and can maintain the shape. The requirements for stability and lying comfort are more resistant to water, dirt and durability, and are of practical value. The reason is that this creation does comply with the requirements of the new patent and is filed according to law.
