Description

  The present invention relates to a tatami mat constructed by attaching a tatami mat to a tatami floor.

Conventionally, there is a tatami that is composed of a tatami mat that is bonded to the surface of the tatami floor with an adhesive to secure waterproofness and rigidity at the boundary between the tatami mat and the tatami floor. (See, for example, Patent Document 1).
Japanese Patent Laid-Open No. 2002-070292

  By the way, the tatami mat described in the above-mentioned Patent Document 1 is a so-called tatami mat with an edge, and the edge is sewn on the side surface of the tatami floor. Therefore, in this kind of tatami mat with a border, on the tatami mat surface, the tatami mat surface is adhered to the entire surface of the tatami floor via an adhesive, and the tatami mat table is closely adhered to the surface of the tatami floor to realize a structure without a gap. However, on the tatami side surface, a needle hole is formed on the side surface of the tatami floor when the edge is sewn to the side surface of the tatami floor. Therefore, in the case where the tatami mat with the edge constructed as described above is washed with water, it is possible to prevent the penetration of water and dirt from the tatami surface into the interior, There is a problem that the penetration of dirt cannot be prevented and the product life (usable period) is shortened due to the generation of bad odor or corrosion due to the penetration of water or dirt.

  On the other hand, in recent years, so-called edgeless tatami mats having no edge have also become widespread. Even in this kind of borderless tatami mat, the tatami mat surface is adhered to the entire surface of the tatami floor with an adhesive, and the tatami mat surface is brought into close contact with the tatami floor surface to realize a structure without any gaps. It is possible to ensure waterproofness and rigidity at the boundary between the tatami mat and the tatami floor. However, if the tatami mat is sewn to the side of the tatami floor, it will not be possible to prevent the penetration of water and dirt from the side of the tatami to the inside in the same manner as the tatami mat with the edge described above. There is a problem that a bad odor is generated or corroded due to the permeation of the product, thereby prolonging the product life.

  The present invention has been made in view of the above circumstances, and its purpose is not only to ensure waterproofness and rigidity at the boundary between the tatami mat and the tatami floor on the tatami mat surface, but also the tatami mat and tatami mat on the tatami mat side. An object of the present invention is to provide a tatami mat that can ensure waterproofness and rigidity at the boundary with the floor, and can be used cleanly and for a long time.

  In the tatami mat according to claim 1, a plurality of synthetic resin plate members are laminated, and at least the uppermost plate member and the lowermost plate member of the plurality of plate members are bonded to the next plate member with an adhesive. In the tatami mat comprising a tatami floor constructed by being bonded to the entire surface and a synthetic resin tatami mat attached to the tatami mat floor, the tatami mat has a substantially back surface on the surface of the tatami mat floor. It is characterized in that it is bonded to the entire area of at least a pair of opposing two side surfaces through an adhesive.

The tatami mat according to claim 2 is characterized in that the back surface of the tatami mat is adhered to the entire surface of the entire circumferential side surface of the tatami floor via an adhesive.
The tatami mat according to claim 3 is characterized in that the back surface of the tatami surface is bonded to a part of the back surface of the tatami floor via an adhesive.

  The tatami mat according to claim 4 is characterized in that the lower part thereof is supported by a support member so that it can stand upright.

  According to the tatami mat of claim 1, the back surface of the tatami surface is bonded to the entire surface of the tatami floor through an adhesive, and the back surface of the tatami surface is at least a pair of facing each other. Since the entire surface of one side is also adhered to the entire surface via an adhesive, the tatami surface is brought into close contact with the entire surface of the tatami floor, and a structure without a gap is realized. In addition to ensuring waterproofness and rigidity at the boundary between the tatami mat and the tatami floor on the surface, the tatami mat is also closely attached to almost the entire area of at least one pair of opposing sides of the tatami floor so that there is no gap. By being realized, it is possible to ensure waterproofness and rigidity at the boundary between the tatami mat and the tatami floor on the side surface of the tatami mat, and thereby it can be used cleanly and for a long period of time.

  According to the tatami mat according to claim 2, since the back surface of the tatami surface is adhered to the entire area of the entire circumferential side surface of the tatami floor via an adhesive, the tatami surface is the entire circumferential side surface of the tatami floor. By being in close contact with substantially the entire area of the tatami mat and realizing a structure without a gap, waterproofness and rigidity at the boundary between the tatami mat and the tatami floor on the tatami side can be more reliably ensured.

  According to the tatami mat of claim 3, since the back surface of the tatami mat is configured to be adhered to a part of the back surface of the tatami floor via an adhesive, the tatami mat is attached to a part of the back surface of the tatami floor. Since the structure without any gaps is also realized, waterproofness and rigidity at the boundary between the tatami mat and the tatami floor on the back surface of the tatami mat can be ensured.

  According to the tatami of claim 4, since the lower part of the tatami is supported by the support member, the tatami is configured so as to be able to stand upright. Therefore, for example, a partition in a place where an unspecified number of people gather such as a shelter at the time of disaster ( It can also be used as a partition, and can be used as a product, and at the same time can ensure human privacy. Basically, it can be used as a normal tatami mat. For example, if there are few partitions without crowding, it is sufficient to use more tatami mats. When dense and a lot of partitions are required, a flexible usage mode can be realized such as increasing the number of partitions used as partitions. Further, there is no need to store the normal tatami mat and the partition as separate equipment, and there is an advantage that the normal tatami mat and the partition can be stored neatly as one equipment.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Note that FIG. 1 shows a vertical side surface of A-A ′ of the edgeless tatami 1 in FIG. 3. As shown in FIG. 3, the rimless tatami 1 is formed, for example, in a size of 1 tatami size, and as shown in FIGS. 3 is attached. The tatami floor 2 is formed by laminating foam 4, plates 5, 6, foam sheets 7, 8 and woven fabrics 9, 10. The foam 4, the plates 5, 6, the foam sheets 7, 8 and the woven fabrics 9, 10 are plate materials referred to in the present invention. In addition, the woven fabric 9 is the uppermost plate material referred to in the present invention, and the woven fabric 10 is the lowermost plate material referred to in the present invention.

  The foam 4 is a plate material made of synthetic resin, and as the material, expanded polystyrene beads, extruded expanded polystyrene, expanded polypropylene beads, and the like are used. The plates 5 and 6 are made of synthetic resin and have rigidity. The materials are polypropylene, polyethylene, polyvinyl chloride, polystyrene, acrylonitrile-butadiene-styrene resin, polymethyl methacrylate, polycarbonate, polyacetal, and tetrafluoroethylene resin. And silicone resin. The foam sheets 7 and 8 are plate materials made of synthetic resin and having an appropriate elasticity, and polyethylene, polypropylene, polystyrene, polyvinyl chloride, and the like are used as the material. The woven fabrics 9 and 10 are made of synthetic resin and have a feel of smoke, and the material is polyethylene, polypropylene, polyamide, polyvinylidene chloride, or the like.

  In this case, on the surface 4 a side of the foam 4, the front surface 4 a of the foam 4 and the back surface 5 a of the plate 5 are bonded together via the adhesive 11 a, and the front surface 5 b of the plate 5 and the back surface 7 a of the foam sheet 7 are adhered. Are adhered to the entire surface via an adhesive 11c, and the front surface 7b of the foam sheet 7 and the back surface 9a of the woven fabric 9 are adhered to each other via the adhesive 11e. On the other hand, on the back surface 4b side of the foam 4, the back surface 4b of the foam 4 and the back surface 6a of the plate 6 are bonded together through an adhesive 11b, and the front surface 6b of the plate 6 and the back surface 8a of the foam sheet 8 are Is adhered to the entire surface via an adhesive 11d, and the front surface 8b of the foam sheet 8 and the rear surface 10a of the woven fabric 10 are adhered to each other via the adhesive 11f. In addition, since the woven fabric 10 is formed in an area smaller than the foam sheet 8, a part of the foam sheet 8 is exposed as the tatami floor 2. Further, as the above-described adhesives 11a to 11f, olefin-based hot melt, synthetic rubber-based adhesive, or the like is used.

  Next, the aspect in which the tatami mat 3 is attached to the tatami floor 2 will be described. The tatami mat 3 has a back surface 3a adhered to the entire surface 2a of the tatami floor 2 (the surface 9b of the woven fabric 9) and the entire circumferential side surface 2b via an adhesive 11g and a back surface 2c. The entire surface (the surface 8b of the foamed sheet 8) is also adhered to the entire surface via an adhesive 11g. With such a configuration, the tatami surface 3 is in close contact with the entire area of the front surface 2a of the tatami floor 2, the entire area of the entire circumferential side surface 2b, and a part of the back surface 2c, thereby realizing a structure without a gap. As the adhesive 11g, an olefin hot melt, a synthetic rubber adhesive, or the like is used in the same manner as the adhesives 11a to 11f described above.

  Now, the case where the edgeless tatami 1 of the above-mentioned structure is washed with water is assumed. When the edgeless tatami 1 is washed with water, for example, a user (washer) may use a hose or the like to discharge water toward the surface 1 a of the edgeless tatami 1, and As water is discharged toward the front surface 1a, water may wrap around from the front surface 1a of the edgeless tatami 1 toward the side surfaces 1b and 1c and the back surface 1d. However, the rimless tatami 1 of the present invention, as described above, has a structure in which the tatami table 3 is in close contact with the entire surface 2a of the tatami floor 2, the entire circumferential side surface 2b, and a part of the back surface 2c so that there is no gap. Therefore, even if water wraps around from the front surface 1a of the rimless tatami 1 toward the side surfaces 1b, 1c and the back surface 1d, water and dirt from the front surface 1a, the side surfaces 1b, 1c and the back surface 1d Penetration will be prevented.

  By the way, as described above, as shown in FIG. 4A, the back surface 3a of the tatami surface 3 is bonded to the four sides of the tatami floor 2 and is folded to the back side. As shown in FIG. 2, the back surface 3a of the tatami surface 3 is a state in which the back surface 3a is adhered to the two sides on the short side of the tatami floor 2 (two side surfaces facing each other in the present invention) and is folded to the back side. Alternatively, as shown in FIG. 4 (c), the back surface 3a of the tatami mat 3 is bonded to the two sides of the tatami floor 2 on the long side (two side surfaces facing each other in the present invention). In this case, it may be folded into the back side, and the mode may be selected according to the required specifications. Moreover, as shown to Fig.5 (a)-(c), the aspect by which the back surface 3a of the tatami surface 3 is only adhere | attached entirely with respect to the surface and side surface of the tatami floor 2, and is not folded in the back side may be sufficient.

  Further, as described above, in the rimless tatami mat 1 described above, the back surface 3a of the tatami surface 3 is bonded to the entire surface 2a of the tatami floor 2 and the entire peripheral side surface 2b via the adhesive 11g. Therefore, the rigidity on the tatami surface and the tatami side surface is ensured. Therefore, the rimless tatami 1 is configured to be able to stand upright without being distorted or warped by supporting the lower portion thereof with a support member. Hereinafter, a mode in which the edgeless tatami 1 of the present invention is used as a partition by being erected through a support member will be described with reference to FIGS. 6 to 8.

  6 and 7, the ridge 12 (supporting member in the present invention) is made of thinned wood, and a slit 12 a having a width slightly larger than the thickness of the edgeless tatami 1 is formed in one direction. Moreover, the eaves 13 (supporting member in the present invention) is made of thinned wood, and slits 13a and 13b having a width slightly larger than the thickness of the edgeless tatami 1 are formed in two directions orthogonal to each other. FIG. 6 shows an example in which two borderless tatami mats 1 are supported upright by the ridges 12 and 13 and are erected so as to form an L-shape as a whole, and an L-shaped partition is formed. Yes. In FIG. 7, the three edgeless tatami mats 1 are supported upright by the ridges 12 and 13 so as to form an L shape as a whole, and another L-shaped partition is formed. An example is shown. In this case, the edgeless tatami mat 1 may be erected so that the side surfaces 1b abut each other, or is erected so that the side surfaces 1b do not abut each other (with a predetermined interval). Also good.

  In FIG. 8, the flange 14 (support member in the present invention) is made of a plastic material, and a slit 14 a having a width slightly larger than the thickness of the edgeless tatami 1 is formed in one direction. FIG. 8 also shows an example in which the two edgeless tatami mats 1 are supported upright by the ridges 14 and are erected so as to form an L shape as a whole, and an L-shaped partition is formed.

  In this embodiment, the example in which the L-shaped partition is formed has been described. However, various types such as a U-shape, a square shape, and a cross shape can be obtained by changing the arrangement of the edgeless tatami 1. It is also possible to form a partition.

  As described above, according to the present embodiment, the back surface 3a of the tatami surface 3 is bonded to the entire surface 2a of the tatami floor 2 via the adhesive 11g, and the back surface 3a of the tatami surface 3 is tatami mat. Since the entire surface of the entire circumference side surface 2b of the floor 2 is also adhered to the entire surface of the floor 2 via the adhesive 11g, the tatami mat 3 is in close contact with the entire area of the surface 2a of the tatami floor 2 so that there is no gap. By being realized, not only is the waterproof and rigidity secured at the boundary between the tatami mat 3 and the tatami floor 2 on the tatami surface, but the tatami mat 3 is also in close contact with the entire circumferential side surface 2b of the tatami floor 2. By realizing a configuration without a gap, it is possible to ensure waterproofness and rigidity at the boundary between the tatami mat 3 and the tatami floor 2 on the side of the tatami mat. it can.

  Moreover, since the back surface 3a of the tatami mat 3 is configured to be adhered to a part of the back surface 2c of the tatami floor 2 via the adhesive 11g, the tatami mat 3 is also applied to a part of the back surface 2c of the tatami floor 2. By realizing a configuration without any gaps, it is possible to ensure waterproofness and rigidity at the boundary between the tatami mat 3 and the tatami floor 2 on the back surface of the tatami mat.

  And by ensuring the rigidity in the boundary of the tatami surface 3 and the tatami floor 2 in the tatami surface and the tatami back surface in this way, the horizontal direction of the tatami surface 3 and the tatami floor 2 (see arrows B1 and B2 in FIG. 3). The vertical direction between the tatami mat 3 and the tatami floor 2 can be prevented by preventing the displacement and securing the rigidity at the boundary between the tatami mat 3 and the tatami floor 2 on the side of the tatami (see arrows C1 and C2 in FIG. 3). Can be prevented, and damage can be avoided. In particular, the fact that such a shift between the tatami mat 3 and the tatami floor 2 can be prevented is particularly effective when used in an environment where there is a high possibility that a certain level of impact is applied to the tatami, such as a judo hall.

  Moreover, since it was configured to be able to stand upright by being supported by the eaves 12-14, it can also be used as a partition in a place where an unspecified number of people gather, such as a shelter in the event of a disaster. Can be used and the privacy of people can be secured. Basically, it can be used as a normal tatami mat. For example, if there are few partitions without crowding, it is sufficient to use more tatami mats. When dense and a lot of partitions are required, a flexible usage mode can be realized such as increasing the number of partitions used as partitions. Further, there is no need to store the normal tatami mat and the partition as separate equipment, and there is an advantage that the normal tatami mat and the partition can be stored neatly as one equipment. Furthermore, forest resources can be used effectively by constructing the firewood 12 and 13 from thinned wood.

The present invention is not limited to the above-described embodiment, and can be modified or expanded as follows.
For example, the structure applied to a borderless tatami of the size of a semi-tatami size may be sufficient. The combination and thickness of the board | plate material which comprises a tatami floor may be another combination and heat. When used as a partition, it is not limited to a configuration in which the long side is directed downward and may be a configuration in which the short side is directed downward.
