Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a tatami mat, and more particularly to a tatami mat having excellent durability and usability.

[0002]

2. Description of the Related Art A tatami mat generally has a tatami floor constituting a core material and a tatami mat constituting a use surface. In this tatami, as shown in FIG. 7, a tatami mat 20c is attached to a tatami floor 10c, and an edge cloth 12c is attached to an edge 11c along the longitudinal direction.
After arranging, this edge 11c is attached with the thread 13c,
Generally, the tatami mat table 20c is fixed to the tatami floor 10c.

[0003]

As described above, in the conventional tatami mats, the tatami mat table 20c and the tatami mat floor 10c have respective edges (1).
1c, etc.), the unity is poor. For this reason, for example, a part near the center of the tatami mat 20c may be displaced from the tatami mat 10c,
0c is likely to rise above the tatami floor 10c. Therefore, the tatami table 20c may be in a rubbed state,
The tatami mat 20c is liable to cause unnecessary fatigue and to deteriorate the durability of the tatami mat 20c.

In recent years, in order to reduce the production cost of tatami mats, hard resin foams such as plate-like foams made of polystyrene resin, wood-based boards (for example, veneer boards), or There is a tendency that the tatami floor 10c is configured using an integrated product of a hard resin foam and a wooden board or the like. The tatami floor 10c is made of such a material having poor elasticity.
In this case, the tatami floor 10c is apt to set, so that the durability of the tatami mat is reduced and the feeling of use of the tatami mat is likely to be reduced in a relatively short time.
In particular, in this type of tatami floor 10c, for example, when a local load is applied from a leg portion of a desk, a chair, or the like, a permanent distortion that is difficult to restore is generated. Become.

Further, as the number of welfare facilities for the aged has increased with the recent aging of society, the use of the traditional Japanese lifestyle, for example, rooms with tatami mats, has been actively promoted in these facilities. However, in a disabled life, people often spill meals (drinks) or stain tatami mats with urinary incontinence and the like, and it is difficult to maintain a clean sanitary environment. Also, at present, a fire caused by tobacco at bedtime causes the fire to be quickly fired after the current tatami mat is ignited, resulting in greater damage. The present invention has been made to solve the above problems, and has as its object to provide a tatami mat having excellent durability and usability.

[0006]

According to a first aspect of the present invention, there is provided a tatami mat having a tatami mat and a tatami mat floor, wherein the tatami mat is arranged in a predetermined molding die. The tatami floor is characterized by using a semi-rigid polyurethane foam foam-molded in a mold.

According to the present invention, a tatami floor is formed using a semi-rigid polyurethane foam having a moderate elasticity.
The durability of the tatami floor is improved. Furthermore, since the semi-rigid polyurethane foam is foam-formed in a state where the tatami mat is placed in the molding die to form the tatami mat, the entire back surface of the tatami mat and the entire front surface of the tatami mat are securely joined to each other. Therefore, since the tatami mat and the tatami mat floor are surely integrated, the durability of the tatami mat is improved. Therefore, according to the present invention, the durability of the entire tatami mat is improved.

In addition, according to the present invention, it is not necessary to use an adhesive or to carry out an attachment or the like when joining the tatami mat and the tatami mat floor. However, also in the present invention, an adhesive or an adhesive may be used together at the time of this joining, and in such a case, the joining becomes more firm.

Further, the "semi-rigid polyurethane foam" according to the present invention is a polyurethane foam having an intermediate cell compressive strength between a flexible foam and a rigid foam and having an open cell structure of 90% or more. The reason for selecting "semi-rigid polyurethane foam" as a material for a tatami floor is as follows. That is, when a rigid foam is used,
The elasticity is poor, the durability of the tatami floor is low, and if a soft foam is used, the rigidity is poor, and it is difficult to obtain the original feeling of use of the tatami mat. On the other hand, a "semi-rigid polyurethane foam" has appropriate elasticity and rigidity and is suitable as a material for tatami floors.

The "tatami table" according to claims 1 to 3 includes, in addition to (a) a tatami table body formed by appropriately knitting natural rush or synthetic rush made of a polymer, etc., (b) resin Also included is one provided with a tatami mat main body using a sheet or the like.
When the above (a) is used, the stitches and the like formed on the back surface function as anchors, and the bonding strength between the tatami mat and the tatami mat floor is increased. In the case of using the above (b), intentional unevenness can be formed on the back surface, and the unevenness can be made to function as an anchor.

The tatami floor can be impregnated with any one of a fragrance, an antibacterial agent, an insect repellent, and a mold repellent to add an aromatic function, an antibacterial function, and the like. . In addition, in the tatami floor that is foam-molded in the molding die, the portion near the end face becomes a skin layer with a low degree of foaming, thereby preventing unnecessary evaporation of fragrances, antibacterial agents, and the like. Thereby, it becomes easy to hold the fragrance, the antibacterial agent and the like for a long period, and the fragrance function, the antibacterial function and the like can be maintained for a long period.

Further, since the tatami floor is made of a semi-rigid polyurethane foam, even if the fragrance function, antibacterial function, etc., decrease with time, an fragrance, an antibacterial agent, etc. can be removed from the outside of the tatami floor with an injection needle or the like. It is easy to refill, and the fragrance function and antibacterial function of the tatami floor can be maintained for a longer period of time. Furthermore, according to the present invention, a tatami floor which a user does not directly contact is impregnated with a fragrance, an antibacterial agent and the like. In other words, the tatami mat directly in contact with the user is not impregnated with an aromatic agent, an antibacterial agent, or the like, so that a tatami mat having excellent functions, such as an aromatic function and an antibacterial function, can be obtained.

According to a third aspect of the present invention, the tatami mat includes a tatami mat main body constituting a surface to be used and a heat conducting sheet disposed on a back surface of the tatami mat main body. It can be embedded in a state of contacting the heat conducting sheet.

That is, since the floor heating function can be added, the convenience of the tatami mat is improved. Moreover, when foaming a tatami floor,
By simply inserting the heat-generating member into the molding die, the heat-generating member can be buried in the tatami mat floor, resulting in the addition of a floor heating function, which increases the labor and cost of tatami manufacturing. There is no. In addition, the "sheet for heat conduction" according to the present invention can be variously selected, and examples thereof include metal foils and sheets (for example, aluminum sheets and the like). Also,
The "heating member" can be variously selected, and examples thereof include a water pipe for passing hot water and a ceramic heater.

[0015] The tatami mat may be such that characters and / or designs are displayed on the tatami mat table. Examples of the design include illustrations of animals and flowers, landscape paintings, art paintings, and the like, and may be monocolor or multicolor. Animals include dogs, cats, birds, and the like, and flowers include tulips, roses, sunflowers, and the like.
This is expected to have the effect of enjoying a different atmosphere in the room when using it, and giving room and affluence to life. As a method of displaying characters and / or patterns on the tatami table, at the stage of providing the tatami table, natural rush or polymer synthetic rush is partially colored so that the pattern is obtained,
Examples include a method of knitting at a predetermined position and a method of printing on a tatami table in a normal plain state.

[0016] The tatami mat may include a flame-retardant layer between the tatami mat surface and the tatami mat floor. By providing this flame-retardant layer, in the event of a fire, compared with a tatami mat having a current natural type tatami mat, a portion and amount of the flammable material can be reduced in a short period of time, and fire damage can be reduced.

The flame-retardant layer is not particularly limited as long as it is made of a material having flame retardancy, but it is not limited to a metal sheet, a flame-retardant polymer film, a woven fabric layer impregnated with a flame retardant, or A nonwoven fabric layer and the like can be mentioned. The thickness of the flame-retardant layer depends on its constituent materials, but is usually 30 to 50 μm.
m, preferably 40 to 50 μm, more preferably 5
Those having a range of 0 to 70 μm are preferable. As the flame-retardant layer, a metal sheet can be used. As the metal of the metal sheet, those having a property of being resistant to rust are preferably used, for example, aluminum, stainless steel, etc., and as described in claim 7, aluminum can be used, and the thickness is 30 to 5 mm.
A 0 μm aluminum foil is preferably used.

[0018] The tatami mat can be made by knitting a synthetic rush of polymer. The type of the polymer is not particularly limited, but may be polyethylene, polypropylene, nylon, or the like.
Of these, polypropylene is preferable as described in claim 9. In the case of a tatami mat made of a synthetic rush made of a polymer, by providing an aluminum foil as the above-mentioned flame retardant layer, even if a drink is spilled, even if the tatami is stained by urinary incontinence, etc., it can be easily washed, Can be dried.

Further, the tatami mat can be used for a welfare facility or a nursing facility.
In the above facilities, taking into account the lifestyle that people with disabilities may contaminate the floor, etc., for example, a flame-retardant layer on a tatami floor and a polymer layer on the flame-retardant layer Of a tatami mat provided with a tatami mat made by knitting synthetic rush made of lime. Further, in consideration of a lifestyle that pays attention to the skin, for example, a mesh-like flame-retardant layer having air permeability is placed on a tatami floor impregnated with an antibacterial agent and an insect repellent. There is an embodiment in which a tatami mat is provided with a tatami mat made by knitting a synthetic rush made of a polymer on which a landscape image is printed.

[0020]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be specifically described with reference to examples. First Embodiment First, a tatami mat according to the first and second aspects of the present invention will be described with reference to FIGS. As shown in FIG. 1, the tatami mat includes a tatami floor 10 and a tatami mat 20 arranged on the surface of the tatami floor 10.
And a reinforcing plate 30 arranged on the back surface of the tatami floor 10, and a cushion material 40 arranged on the back surface of the reinforcing plate 30.

Among them, the tatami floor (size: 900 mm × 1
800 mm × 20 mm) 10 is a semi-rigid polyurethane foam (trade name; “RM
-5002 ", manufactured by Polyurethane Chemicals Ltd.). In addition, the tatami floor 10 is impregnated with an air freshener (trade name “hinoki thiol”) 14 that gives off the scent of “cypress”.

The fragrance to be impregnated in the tatami floor 10 is not limited to this, and may be, for example, a fragrance that produces a flower scent (lavender, rose, etc.). In addition, in the present invention, the tatami floor 10 can be impregnated with one or more selected from antibacterial agents, insect repellents, and mold repellents together with or instead of the fragrance. For example,
Zeolite supporting silver or copper, glass in which silver or copper is melted, or the like may be used, and these function as antibacterial agents, insect repellents, and mold repellents.

The tatami mat 20 has a natural type tatami mat main body 21 formed by weaving rush, but may have an artificial tatami mat main body 21 formed by using a resin sheet or the like. For example, the surface of a flexible resin sheet (for example, having a thickness of about 0.3 to 3 mm) made of a vinyl-based resin such as polyvinyl chloride or an olefin-based resin such as polypropylene is tatami-like unevenness imitating a tatami mat of rush. The tatami mat main body 21 in which the pattern is formed by embossing may be provided.

Further, as the reinforcing plate 30, for example, a veneer plate or cardboard (for example, recycled paper) or the like is used, and is mainly intended to increase the rigidity of the entire tatami mat. However,
In this tatami mat, the tatami floor 10 itself made of a semi-rigid polyurethane foam has sufficient rigidity, so that the use of the reinforcing plate 30 can be omitted.

Incidentally, also in the main tatami mat, a "cloth cloth" can be attached to the edge of the tatami for the purpose of improving the design, etc., and in this case, it is desirable to use the reinforcing plate 30. This attachment is generally performed by folding the yarn on both the front and back sides of the tatami mat. When this reinforcing plate 30 is not used, the “thread fold-back portion” located on the back side of the tatami mat is the tatami floor 10. This is because there is a risk of digging into. Further, in the present tatami mat, it is sufficient to use the rim cloth as a mere decoration. Therefore, the rim cloth can be fixed to the tatami mat by a method such as bonding.

The cushion material 40 is made of, for example, a rubber sheet (for example, SBR,
Or, it is configured using a natural rubber or the like or a nonwoven fabric. This cushion material 40 is used for the purpose of giving cushion performance to the main tatami mat in consideration of the case where the main tatami mat is mainly placed on a hard flooring material such as a flooring material. Moreover, since sufficient frictional resistance can be added to the back side of the main tatami mat by the cushion material 40, a slip prevention effect can also be obtained. In addition, in the tatami mat of the present invention, the use of the cushion material 40 may be omitted.

Next, a specific example of the method for manufacturing the main tatami mat will be described with reference to FIG. First, the tatami mat 20 is placed in the molding space 51 of the lower mold 50, and the mixed liquid 15 including the liquid A on the polyol side, the liquid B on the isocyanate side, and the fragrance 14 is introduced onto the tatami mat 20. In this example, the liquid A was composed using a polyether polyol, water, a crosslinking agent, a catalyst, and a pigment, and the liquid B was composed using a polymeric MDI. It is not limited to.

Subsequently, the reinforcing plate 30 and the cushion material 40 are inserted into the molding space 51 in this order, and the upper mold 53 is further inserted into the lower mold 50.
Place it on top to clamp the mold. Then, under predetermined molding conditions (for example, mold temperature; 40 to 50 degrees Celsius, curing time;
7 minutes), the polymerization reaction of the mixed solution 15 and foaming (for example,
(Expansion ratio: about 5 to 10 times), the main tatami mat is obtained. The tatami is subjected to post-processing such as "burr removal" as needed.

In this tatami mat, as shown in FIG. 3, the durability of the tatami floor 10 is improved because the tatami floor 10 is made of a semi-rigid polyurethane foam having an appropriate elasticity. Further, the tatami floor 10 is foam-formed in a state where the tatami table 20 is arranged in a molding die including the upper die 53 and the lower die 50. At this time, the stitches and the like formed on the back surface of the tatami table 20 function as anchors.
Is securely and firmly joined to the entire surface. For example, even when an external force that causes a lateral displacement is applied to the tatami table 20, the tatami table 20 always tries to move integrally with the tatami floor 10, so that the tatami table 20 does not cause unnecessary lateral displacement or fatigue. The durability of the tatami mat 20 is improved. Therefore, according to the present invention, the durability of the entire tatami mat is improved.

In this embodiment, an example is shown in which the tatami mat 20 is arranged only on the surface of the tatami mat floor 10.
Placed on the back and four end faces together with the front of the tatami floor 1
0 may be surrounded by the tatami mat 20. In particular, according to the aspect in which the tatami mat surface 20 is also arranged on the back surface of the tatami floor 10, a so-called "reversible type" tatami mat having both front and back surfaces can be used.

In the tatami mats, the tatami floor 10 carries the fragrance 14 which gives off the scent of "cypress", so that the user of the tatami mats feels as if they are performing "forest bathing". be able to. And according to this tatami mat, this fragrance function can be maintained for a long period of time. That is, in the tatami floor 10 foamed and molded in the molding die, the portion near the end face has a low degree of foaming, and the hard skin layer 18
It has become. For this reason, the fragrance of the fragrance 14 is
It is prevented from evaporating in a useless direction such as the end face direction,
This is because the fragrance 14 evaporates little by little in the direction of the tatami mat 20 while lurking in the tatami floor 10.

When the user sits on the main tatami mat or lays down on the tatami mat, the user can enjoy the fragrance of the cypress that evaporates slightly from the tatami mat table 20. However, when the user walks on the tatami mat, an external force is applied to the tatami floor 10 by the leg of the user, and the tatami floor 10 undergoes an appropriate elastic deformation.
At this time, the fragrance 14 impregnated in the tatami floor 10 is strongly evaporated, and a pleasant fragrance is strongly drifted around the main tatami mat.

When the fragrance function of the tatami mat is reduced with time, the fragrance function is restored by replenishing the tatami floor 10 with the fragrance 14 using an injection needle or the like. Also,
At this time, by injecting another fragrance that produces a fragrance different from the fragrance 14, the user of the tatami mat can also change his / her mind.

Embodiment 2 Next, a tatami mat according to a third embodiment of the present invention will be described with reference to FIG. In this tatami, (1) a tatami table 20a is formed by using a natural or artificial tatami table main body 21a and a heat conduction sheet (for example, 0.
(A thickness of about 1 mm) 22a and (2) a heating member 17 on the front side of the tatami floor 10a.

m intervals). In this embodiment,
As the heat generating member 17a, a water guide pipe (for example, a resin tube having an outer shape of about 10 mm and an inner diameter of about 8 mm) through which the hot water 60a passes is exemplified, but a heat generating member 17a of another mode such as a ceramic heater may be used. .

When manufacturing the tatami mat according to the second embodiment, the tatami mat 2 comprising only the tatami mat main body 21 shown in FIG.
Instead of 0, a tatami mat 20a provided with a tatami floor 10a and a heat conducting sheet 22a is used. In addition, the heat generating member 17a is placed in the molding space 51 of the lower die 50 in a state where the heat generating member 17a is fixed on the back surface of the tatami mat 20a in advance. At this time, it is necessary to direct the heat generating member 17a toward the opening of the lower die 50. Next, the mixed solution 15 is introduced onto the integrated product, and further,
When the mixed liquid 15 is foamed after the reinforcing plate 30 and the cushion material 40 are introduced, the tatami mat of Example 2 can be obtained.

According to the tatami mat, the following effects can be obtained in addition to the effects of the first embodiment. That is, since a part of the outer peripheral surface of the heat generating member 17a is in direct contact with the heat conducting sheet 22a, the hot water 60 passing through the heat generating member 17a is not required.
a is efficiently transmitted to the heat transfer sheet 22a.
Moreover, since the heat conduction sheet 22a is arranged so as to cover the entire back surface of the tatami mat main body 21a, the user can comfortably use the tatami mat as a floor heating device. Furthermore, with the heating member 17a inserted, the tatami floor 1
0 is foam-molded, and the heat-generating member 17a is embedded in the tatami floor 10 without any discomfort.
The use of the tatami mat does not impair the use of the tatami mat.

Also, in the tatami mat of the second embodiment, the tatami mat floor 20
Although a is impregnated with the fragrance, the tatami floor 20a is appropriately heated, so that the evaporation of the fragrance is promoted. Moreover, similar to the tatami mat of the first embodiment, a skin layer (not shown in FIG. 4) is formed on the end surface side of the tatami floor 20a, and the meaningless transpiration of the fragrance can be reliably prevented. Even with the two tatami mats, you can enjoy a pleasant scent for a long time.

According to the first and second aspects of the present invention, unlike the present embodiment, the use of the heat conducting sheet 22a can be omitted by disposing the heat generating members 17a in a dense state on the back surface of the tatami mat 20a. it can.
