DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tatami floor using dried peach stems or leaves.

[0002]

2. Description of the Related Art A tatami mat has a structure in which tatami mats woven with rush stems are covered on a tatami mat floor and sewn. It is becoming difficult to secure straw as raw material.

As a result, using natural straw makes tatami expensive. Therefore, as described in JP-A-4-16668 and the like, the amount of straw used can be reduced,
Attempts have been made to use a lightweight resin, inorganic fiber, wood material, or the like as a substitute for straw, or to have a structure that does not generate toxic gas during a fire.

FIG. 3 is a sectional view of a tatami floor in which the generation of toxic gas is prevented. A second layer 2 formed by molding inorganic fibers using a binder is provided on a first layer 1 made of foamed resin. , The second
It has a laminated structure in which a third wooden layer 3 is further provided on the layer 2. In addition, 4 is a tatami table and 5 is an edge band.

[0005]

However, as described above, in a structure using no straw at all, it is fatal that the elasticity peculiar to a straw-made tatami floor is poor as compared with a tatami mat using straw. Not suitable for Japanese who prefer tatami.

[0006] Therefore, although tatami flooring using straw is the most preferable, even if it is expensive, another problem is that straw is weak in mechanical strength, especially in tension, so that it deteriorates quickly and has a short life. .

[0007] Further, since the straw is short in length, it must be replenished several times even on the makeup distribution side, and therefore the mechanical strength is weak. Therefore, a large amount of straw must be staggered and stacked in many layers, and in combination with the low strength of the straw itself, a large amount of straw must be used.

[0008] As described above, the tatami floor made of straw has a short life,
Moreover, they require a large amount of straw, which makes them more expensive.

[0009] The technical problem of the present invention is to focus on such a problem, and it is rich in elasticity like a tatami floor made of straw, has high mechanical strength, does not require replenishment, has a long life and is inexpensive. The purpose is to realize a tatami floor.

[0010]

The present invention uses dried peach stalks and leaves as a material for tatami flooring instead of straw. Even if it does, it can be secured relatively cheaply and stably throughout the year.

A first aspect of the present invention is a tatami floor in which a dried moon peach stem is used for at least one of the vertical arrangement and the decorative arrangement of the tatami floor. As described above, dried peach stalks are used for at least one of the vertical arrangement and the makeup arrangement of the tatami floor, but since the peaches can be relatively easily secured in the Okinawa region, there is no worry about lack of raw materials. As a result, there is no increase in cost.

The stem of the moon peach is a fibrous material having a high tensile strength. In addition, since the moon peach has a strong insect repellent and antiseptic action, it does not easily deteriorate and has a long life. Therefore, if dry moon peach stalks are used as the vertical arrangement or the decorative arrangement of the tatami floor, the tatami floor has a long life and is economical as a result.

[0013] A second aspect of the present invention is that a dried moon peach stalk is used as at least the vertical arrangement of the tatami floor and the decorative arrangement, and the full length of the peach stalk constituting the decorative arrangement is a tatami mat. It is a tatami floor equal in width.

[0014] As described above, at least the total length of the moon peach stalks constituting the makeup arrangement is equal to the width of the tatami floor, so that the addition is unnecessary. As a result, the tensile strength is much higher than that of a structure in which short straws are added to each other to form a decorative arrangement, such as a straw tatami floor. The vertical arrangement is made up of a plurality of moon peach stalks, but the moon peach stalks are much longer than the straw and the number of additions is small, so that the strength in the vertical arrangement direction is sufficient.

[0015] Therefore, in addition to the high tensile strength of the moon peach stem, the tatami floor has a longer life due to the small number of vertical arrangements and the absence of cosmetic arrangements. The result is an inexpensive tatami floor in the long run. Since there is no need to add makeup in the middle, the work at the time of production is simple and suitable for automation.

A third aspect of the present invention is a tatami floor, wherein the moon peach stalk according to the first or second aspect is mechanically pressed and then dried. As described above, since the peach stalks used for the vertical arrangement of the tatami floor and the makeup arrangement are used by pressing and removing moisture, the peach after squeezing out the moon peach liquid used as an insect repellent or a fragrance is used. Since stems can be used, tatami floor materials can be produced at lower cost, and tatami floors can be manufactured at low cost. In addition, the squeezing softens and increases the elasticity of the peach pedicles, so that a tatami floor with an excellent touch can be realized, especially when used on the surface side of the tatami floor.

According to a fourth aspect of the present invention, there is provided a tatami floor in which dried moon peach leaves are mixed in addition to the moon peach stem according to any one of the first to third aspects. Moon peach leaves are particularly strong in insect repellent and antiseptic action. Thus, if dried moon peach leaves are mixed in addition to the moon peach stem, the tatami floor will have a longer life due to the insect repellent and antiseptic action. Become.

A fifth aspect of the present invention is a tatami floor in which the tatami floor according to any one of the first to fourth aspects is laminated on at least one surface of one panel. Thus, 1
In the case of a configuration in which a layer of a tatami floor made of dried moon peaches is laminated on one or both sides of a single panel, the use of a lightweight panel makes the entire tatami floor light.

Further, if an inexpensive panel is used, the amount of moon peach stalks used can be reduced and supplied at a lower cost. Moon peach stem
Since the tensile strength is strong, even if the usage of moon peach stem is reduced, there is no danger that the life of the moon peach tatami floor will be shortened.

[0020]

EXAMPLE Next, how the tatami floor according to the present invention is actually embodied will be described with reference to examples. FIG. 1 is a longitudinal sectional view showing an embodiment of a tatami floor according to the present invention. (1) shows the state of the tatami floor, and (2) shows the completed state with the tatami mat covering the tatami mat, showing the vicinity of the tatami edge on one side. Reference numeral 6 denotes a tatami floor, in which vertical arrangements 7 made of dried moon peach stalks and decorative arrangements 8 made of dried moon peach stalks are alternately stacked so as to be orthogonal to each other.

The fabric 9 is woven with the thread 10 in a state where the fabric 9 and the like are covered on both sides. The leaves of the moon peach may be dried and mixed into the vertical arrangement 7 and the decorative arrangement 8 constituting the tatami floor 6. (2) As shown in the figure, when the tatami mat 4 is put on the surface of the tatami mat floor 6 and the edge band 5 is put on both edges and sewn,
Tatami is completed.

In the illustrated embodiment, the entire tatami floor is made of dried moon peach stems and leaves. The tatami floor is made of conventional straw, and a panel made of synthetic resin or wood is used in recent years. In a tatami floor containing a part of the tatami floor, a composition in which dried moon peach stems and leaves are partially mixed can also provide an effect of hygiene and life extension by insect repellent and preservative actions.

FIG. 2 shows another embodiment of the present invention, in which (a)
Is a cross-sectional view of an embodiment in which panels are sandwiched between the moon and peach layers, (b) is a plan view of a tatami floor during manufacture of a tatami floor, and (c) is a plan view of an embodiment of a tatami floor with moon peaches arranged diagonally. is there.

According to a fifth aspect of the present invention, a single panel may be used, and at least one surface thereof may be provided with a layer made of dried moon peach stalks. Of course, moon peach stem layers may be provided on both sides of the panel, but FIG. 2A shows an embodiment in which moon peach stem layers 12 and 13 are provided on both sides of the panel 11 in this way. In this embodiment, 7 is a vertical arrangement and 8 is a cosmetic arrangement.

If the panel 11 is sandwiched between the moon peach stem layers 12 and 13 as shown in the illustrated example, if the tatami mat becomes dirty, the tatami mat is turned over and a new tatami mat is replaced. There is an advantage that can be. As the panel 11, foamed polyurethane or foamed polystyrene is suitable, but wood such as a plywood is also effective.

FIG. 2 (b) is a plan view of an embodiment in which the total length of the moon peach stalk constituting the makeup arrangement is equal to the width of the tatami mat. That is, it is a plan view of a state in which moon peaches for the decorative arrangement 8 are overlapped during the production of the tatami floor. Makeup arrangement 8
Are all longer than the width W of the tatami floor. In the case of moon peach, the height of the stem is 1 to 2 meters, so that a single moon peach stem can cover the entire width W of the tatami floor without adding like a straw.

As described above, the makeup arrangement 8 is formed by using only the moon peaches 8k longer than the total width W of the tatami floor, and is alternately overlapped with the vertical arrangement 7.
When the both ends 8a and 8b of the makeup distribution moon peach stalk 8k, which are longer than the tatami width W, are cut off in a state of being compressed to the thickness of the tatami floor, the tatami floor is completed. Therefore, since it is not necessary to add the makeup arrangement 8 on the way, the work at the time of manufacture is simple and suitable for automation, and the strength is improved.

7t is a moon peach stem for vertical arrangement, but since the length of the tatami floor in the longitudinal direction is 180 cm, it is difficult to cover the entire length of the tatami mat without adding it, even though it is a moon peach stem.
As shown in the drawing, it is necessary to add one or two times. However, as compared with the case of straw, the number of times of replenishment can be extremely reduced, so that the workability is improved and the production work is simpler, and the strength is improved, similarly to the makeup arrangement 8 side.

In order to increase the strength of the tatami floor, it is effective to dispose moon peaches in an oblique direction as shown in FIG. In this case, the moon peach stalks 19 for oblique distribution are preferably arranged in two directions and, moreover, cross each other as indicated by arrows a ₁ and a ₂ . One may be crossed in the layer, but the layer is directed in the arrow a ₁ direction, the layer having the other by directing the arrow a ₂ direction, may be crossed oblique layers to each other.

In each embodiment shown in FIG. 2, dried moon peach leaves may be woven in addition to moon peach stems. That is, the stem and leaves of the moon peach may be woven in a separated state, or may be woven in a state in which the stem has leaves.

The leaves and stems of the moon peach used for the tatami floor of the present invention are as follows:
It may be simply dried, but it may be fragrance, preservative,
After extracting the insect repellent and the like, the moon peach stem and leaves can be dried and used.

In the latter case, since high heat is applied by steam or the like in the extraction step, even if insects or eggs are attached, they are completely killed and sterilized. Therefore, when used for a tatami floor, it is extremely effective in terms of hygiene, insect repellency and preservation, and is also effective in improving the life.

[0033]

According to the first aspect, dried peach stalks are used for at least one of the vertical arrangement and the decorative arrangement of the tatami floor, but since the peach can be relatively easily secured in the Okinawa region, There is no need to worry about shortages of raw materials, and as a result there is no increase in cost.

The stem of the moon peach is a fibrous material having a high tensile strength. In addition, the moon peach has a strong insect repellent and antiseptic action, so that it is hardly deteriorated and has a long life. Therefore, if dry moon peach stalks are used as the vertical arrangement or the decorative arrangement of the tatami floor, the tatami floor has a long life and is economical as a result.

According to the second aspect, at least the total length of the moon peach stems constituting the makeup arrangement is equal to the width of the tatami floor.
No refilling is required. As a result, the tensile strength is much higher than that of a structure in which short straws are added to each other to form a decorative arrangement, such as a straw tatami floor. The vertical arrangement consists of multiple moon peach stems, but the moon peach stem is much longer than straw,
Since the number of additions is small, the strength in the vertical direction is sufficient.

Therefore, in addition to the high tensile strength of the moon peach, the tatami floor has a longer life due to the small number of vertical additions and the absence of makeup additions. The result is an inexpensive tatami floor in the long run. Since there is no need to add makeup in the middle, the work at the time of production is simple and suitable for automation.

According to the third aspect, as the moon peach stalks used for vertical arrangement of the tatami floor and makeup arrangement, the water squeezed to remove water is used, so that the moon peach sap used as a preservative or a fragrance is squeezed out. Since the moon peach stalks after use can be used, it becomes a cheaper tatami floor material, and the tatami floor can be manufactured at low cost. In addition, the squeezing softens and increases the elasticity of the peach pedicles, so that a tatami floor with an excellent touch can be realized, especially when used on the surface side of the tatami floor.

Since moon peach leaves are particularly strong in insect repellent and antiseptic action, if the dried moon peach leaves are mixed with the moon peach stalks as in claim 4, the tatami mats by the insect repellent and antiseptic action. The floor has a longer life.

According to a fifth aspect of the present invention, in a configuration in which a layer of a tatami floor made of dried moon peaches is laminated on one or both sides of one panel, the entire tatami floor can be made lightweight by using a lightweight panel. Becomes

If an inexpensive panel is used, it is possible to reduce the amount of peach stalks to be used and to supply the peach at a lower cost. Moon peach stem
Since the tensile strength is strong, even if the usage of moon peach stem is reduced, there is no danger that the life of the moon peach tatami floor will be shortened.
