JP5595769B2 - Barrier-free tatami mat - Google Patents

Description

  The present invention relates to a tatami mat in which a tatami corner can be easily installed in a western house of a general house, between board plates of a facility, a lobby, and the like, and particularly relates to a tatami mat corresponding to barrier-free.

  In recent years, interiors have become increasingly westernized in buildings such as houses, and flooring and carpets are frequently used as flooring materials, while the goodness of Japanese-style rooms has been recognized again. Under such circumstances, “laying tatami mats” that can easily create a tatami corner and create a taste of a Japanese-style room simply by laying them on flooring materials such as flooring and carpets have attracted attention.

  This tatami mat was obtained by weaving natural grass or artificial cylindrical fiber yarn on the surface of a plate-like base material having a size of about half tatami mat mainly composed of wood fiberboard, plywood or other boards. It consists of a tatami mat attached.

  Such a tatami mat can create a tatami corner and create a taste of a Japanese-style room simply by laying the required number of floors on the existing floor surface as described above, but between the existing floor surface and the tatami mat surface. There is a problem in that there is a risk that the elderly may fall over such a step. In other words, there is still room for improvement in the tatami mats where such a level difference occurs in the current situation where barrier-free housing and facilities are required as the aging society progresses.

  Therefore, as a technique that can solve such a problem, a technique that surrounds a surrounding tatami laid on an existing floor with a frame material formed in an inclined shape has been proposed. For example, in Patent Document 1, the inner side in contact with the tatami mat is formed as a thick piece, and the outer side opposite to the thick piece is formed into a thin piece having a downwardly inclined surface, and the back side of each member. An enveloping frame in which tenon processing is applied to the end edge portion to form a connecting portion is disclosed, and Patent Document 2 discloses a gentle slope on a step portion formed on the outer surface of a floor surface and a tiled tatami mat (that is, a tatami mat). An enclosure frame is disclosed in which a frame member having a frame is attached and a thin upper side portion of the frame member is overlapped with an end portion of a tile-like tatami to cover and protect. If these techniques are used, the level difference between the floor surface and the tatami mat can be eliminated to some extent.

Utility model registration No. 3073957 JP 2002-317547 A

  However, in the former technique, the inner circumference of the enclosure frame is slightly larger than the outer circumference of the arrangement tatami in consideration of the occurrence of some dimensional errors so that the installation can be easily performed when surrounding the arrangement tatami with the frame material. In this way, the frame member is made, but when the dimensional error between the two becomes large, a gap is generated between the surrounding frame and the edge of the tatami mat. Then, although the level difference between the floor surface and the tatami mat can be eliminated by installing the enclosure frame, there is a risk that the elderly will fall over the newly formed gap.

  In the latter technique, since the upper edge of the thin frame material is covered and protected at the end of the tiled tatami mat, the gap does not occur as in the former, but the thickness of the upper edge can be increased. If there is a new level difference between the tatami mat and the elderly, etc., it will cause a problem, and conversely, if the thickness of the upper side is reduced, the upper side is likely to be damaged during transportation or construction. .

  In addition, since the tatami mat itself is not reinforced in both technologies, for example, when a care vehicle such as a heavy wheelchair is brought close to the tatami mat, such a care vehicle gets over the frame material and lays the tatami mat. If you ride on the top of the frame, a dent will form in the soft tatami mat and a step will be created between it and the frame material. There was a problem that the wheel of the care vehicle hit the corner and the frame material was damaged.

  Therefore, a main problem of the present invention is to provide a barrier-free tatami mat corresponding to barrier-free which can surely eliminate a step formed between the existing floor and a necessary place, and further, It is to provide a barrier-free tatami mat that does not cause dents or scratches even when a care vehicle such as a wheelchair rides.

The invention described in "Claim 1"
(A) A tatami floor 12 provided with an inclined portion 12a whose thickness is changed in an inclined shape so as to be an upward gradient from the end face toward the center, at least on one side of a rectangular plate-like base material made of wood fiber board. When,

(D) The inclined portion 12a is compression-molded by a press.
Barrier-free tatami mat 10.

  In the present invention, since the inclined portion 12a is provided on at least one side portion of the tatami floor 12 so that the thickness thereof is changed so as to be inclined upward from the end surface toward the center, the inclined portion 12a is provided. In the side portion, the step between the floor surface F and the tatami mat 10 can be eliminated without using an inclined frame member or the like. For this reason, there is a problem that a gap or a new step is generated between the frame material and the tatami mat as in the conventional technique of eliminating the step between the floor surface and the tatami mat using a surrounding frame. There is nothing to do and it looks good.

In addition, it is preferable that thickness h1 of the tatami mat 10 side part end surface in which the inclination part 12a was provided shall be less than 3 mm. This is because it is possible to more effectively prevent an elderly person or the like from hitting the tatami mat 10 and falling over.
The barrier-free tatami mat 10 of the present invention is characterized in that “the inclined portion 12a is compression-molded by a press”, and thus undergoes a simple and efficient manufacturing process called compression molding. As a result, the mechanical strength of the inclined portion 12a can be easily and reliably improved, and a heavy-duty nursing care vehicle can be climbed up to the inclined portion 12a.

The invention described in "Claim 2" is that, in the barrier-free placing tatami 10 according to Claim 1, "the reinforcing layer 16 impregnated with a synthetic resin is provided on the surface side of the inclined portion 12a". those wherein, even be reinforced by providing the reinforcing layer 16 in this manner to the inclined portion 12a, it is possible to make ride care vehicle with a weight such as a wheelchair to the inclined portion.

  According to the present invention, the step formed between the floor and the existing floor can be surely eliminated at a necessary location, and further, a barrier that does not cause dents or scratches even when a care vehicle such as a wheelchair rides on the floor. Free-standing tatami mats can be provided.

It is a bird's-eye view which shows an example of the usage condition of the barrier free placement tatami of one Example of this invention. It is a perspective view which shows the outline | summary of the barrier-free placing tatami of one Example of this invention. It is AA sectional drawing in FIG.

  The present invention will be described below with reference to the illustrated embodiments. FIG. 1 is a bird's-eye view showing an example of a usage mode of a barrier-free tatami mat 10 (hereinafter also simply referred to as “laying tatami 10”) of the present invention. As shown in the figure, the tatami mat 10 of the present invention can be set up on a tatami corner simply by being placed on an existing floor surface F, and the taste of a Japanese-style room can be created in the space. In addition, the code | symbol f in FIG. 1 represents the flooring material which comprises a floor surface, and the code | symbol T represents the conventional tatami mat about the size of a semi-tatami mat. The symbol W represents a wall that partitions the room, and the symbol D represents a hinged door that moves while sliding on the sill 4 of the opening 2 provided between the walls W.

  As shown in FIGS. 2 and 3, the tatami mat 10 according to one embodiment of the present invention is generally composed of a tatami floor 12 and a tatami table 14.

The tatami floor 12 is a rectangular plate-like member made of wood fiber board. As the wood fiber board used as the tatami floor 12, an insulation board (soft fiber board) having a thickness h2 of about 10 to 50 mm and an apparent density of about 0.2 to 0.35 g / cm ³ is used. It is particularly suitable from the viewpoints of properties, heat insulation, soundproofing and the like. In addition, when the thickness h2 of the tatami floor 12 is about 10 to 20 mm, it can be handled by a single layer of the insulation board. However, when the thickness h2 of the tatami floor 12 is larger than 20 mm, a plurality of sheets can be used. An insulation board may be laminated, or an insulation board and a polystyrene foam board may be laminated.

  In addition, the size of the tatami floor 12 is not particularly limited, and may be a tatami mat size or a half tatami mat size.

  And at least one side part of this tatami floor 12 is provided with an inclined part 12a whose thickness is changed in an inclined shape so as to rise upward from the end face toward the center. The inclined portion 12a is for preventing a step between the floor surface and the tatami mat 10 when the tatami mat 10 is placed on the floor surface F. It is preferable that the thickness (height) h1 of the end face that becomes the thinnest when 10 is completed is 3 mm or less. By setting the thickness h1 of the end face in such a range, it is possible to more effectively prevent an elderly person or the like from hitting the tatami 10 and falling down. In addition, the width L of the inclined portion 12a provided from the end face of the tatami floor 12 toward the center is appropriately set depending on the size of the tatami floor 12. For example, the tatami floor 12 is formed in a square having a side of 820 mm. If it is, it is preferable to set the width L of the inclined portion 12a to about 300 mm.

  2 and 3 show the case where the inclined portion 12a is provided on the entire side of the tatami floor 12, the inclined portion 12a may be provided on at least one side of the tatami floor 12. For example, the aspect may be any, for example, although not illustrated, it may be provided only in a necessary portion on one side of the tatami floor 12, or the inclined portion 12a may be provided on two adjacent sides of the tatami floor 12, It may be provided on all three sides or all four sides.

  Examples of the method of providing the inclined portion 12a on the tatami floor 12 include a method of cutting or grinding a predetermined position of a plate-like member made of wood fiber board, a method of compression molding using a mold, and the like. In particular, a method of forming the inclined portion 12a by compression molding is preferable. If the inclined portion 12a is formed by compression molding, waste such as scraps is not generated, and the inclined portion 12a can be formed easily and efficiently, and the apparent density of the inclined portion 12a is improved. As a result, the mechanical strength of the portion can be improved, so that a heavy-duty nursing vehicle such as a wheelchair can be climbed up to the inclined portion 12a.

  Furthermore, after applying and impregnating synthetic resin such as acrylic resin, EVA (ethylene-vinyl acetate copolymer) resin, vinyl acetate resin and phenol resin on the surface side of the inclined portion 12a, The reinforcing layer 16 may be provided by curing. Thus, by providing the reinforcing layer 16 on the surface side of the inclined portion 12a and reinforcing it, a heavy nursing care vehicle such as a wheelchair can be run up to the inclined portion 12a.

  The tatami surface 14 is a sheet-like member obtained by weaving natural cypress or an artificial cylindrical fiber-making yarn obtained by twisting a machine-made paper made into a thin slit into a cylindrical shape. As shown in FIG. 3, the tatami surface 14 covers the surface and side surfaces of the tatami floor 12 and is attached so that the front end of the tatami surface 14 is wound around the back surface of the tatami floor 12.

  In the example shown in FIGS. 2 and 3, no processing is performed on the edge of the tatami mat 10 formed by sticking the tatami surface 14 to the tatami floor 12, but a tatami edge (not shown) is formed on the edge. May be attached.

  EXAMPLES The present invention will be specifically described below with reference to examples, but the present invention is not limited to the examples.

[Example 1]
After wet forming, 80% by weight of fibers obtained by digesting wood chips at high temperature and high pressure, 20% by weight of phenol resin as a binder component, and those to which necessary papermaking aids such as a sizing agent are added, are subjected to wet forming. Was dried with a dryer so as to be in a semi-cured state, to obtain a wood fiber board (insulation board) with an apparent density of 0.24 g / cm ³ and a thickness of 15 mm.

Subsequently, an acrylic resin (manufactured by Konishi Co., Ltd.) was spray-applied so that the coating amount was 100 g / m ^{2 at} the inclined portion forming position of the obtained wood fiber board, and then the impregnated position had a predetermined shape This wood fiber board was set in a mold provided with an inclined surface for forming an inclined portion and hot pressed at 180 ° C. for 3 to 4 minutes. Thereby, the tatami floor in which the slope part compressed so that the height of the end surface was 1 mm and the apparent density was 0.36 g / cm ³ was formed on one side of the wood fiber board was completed.

  Here, with respect to the inclined portion of this tatami floor, the amount of dent (mm) when a surface load of 100 kgf (980 N) was applied in the range of 5 cm square was measured using an autograph (precision universal testing machine). As a result, since the dent amount is less than 1 mm, there is no possibility of causing a problem that the inclined portion is easily recessed even if the wheelchair rides on the inclined portion.

  Then, the tatami mat was completely covered with the tatami surface from the surface to the side surface of the completed tatami floor, and the tatami mat was attached by sticking the front end of the tatami surface to the back surface of the tatami floor 12.

In addition, the manufacturing method of a tatami mat is as follows. That is, a machine-made Japanese paper obtained by dyeing softwood pulp green and making paper with a basis weight of 18 g / m ² was cut to a width of 25 mm, twisted into a cylinder with 9 to 10 rolls, and about 0. A cylindrical fiber-making yarn having a thickness of about 1.2 mm having a 5 mm diameter cavity was formed. Then, this cylindrical fiber yarn is dipped and dried in a mixed solution of acrylic resin, wax and fluororesin to form a coat layer on the surface, and then this cylindrical fiber yarn is used as a warp made of cotton yarn. As a result, a tatami mat with a weaving density of 0.8 kg / m ² was obtained.

  Moreover, except that the acrylic resin was not applied and impregnated at the inclined portion forming position of the wood fiber board obtained as a comparison, a placing tatami was produced in the same manner as in the above example. It was found that the dent amount of the inclined part of the tatami floor measured under the same conditions greatly exceeded 1 mm, and therefore, when riding on the inclined part with a wheelchair, the inclined part could easily be dented and damaged.

[Example 2]
After wet forming, 95% by weight of fiber obtained by digesting wood chips at high temperature and high pressure, 5% by weight of poval resin as a binder component, and adding necessary papermaking aids such as sizing agents to these, By drying, a wood fiber board (insulation board) having an apparent density of 0.24 g / cm ³ and a thickness of 15 mm was obtained.

Subsequently, an acrylic resin (manufactured by Konishi Co., Ltd.) was spray-applied so that the coating amount was 100 g / m ^{2 at} the inclined portion forming position of the obtained wood fiber board, and then the impregnated position had a predetermined shape This wood fiber board was set in a mold provided with an inclined surface for forming an inclined portion and hot pressed at 180 ° C. for 3 to 4 minutes. Thereby, the tatami floor in which the slope part compressed so that the height of the end surface was 1 mm and the apparent density was 0.48 g / cm ³ was formed on one side of the wood fiber board.

  Here, with respect to the inclined part of this tatami floor, using an autograph (precision universal testing machine), the amount of dent (mm) when a surface load of 100 kgf (980 N) is applied in a 5 cm square range is measured. As a result, since the dent amount is less than 1 mm, there is no possibility that the inclined portion is easily recessed even if the inclined portion is ridden with a wheelchair.

  Then, the tatami mat was completely covered with the tatami surface from the surface to the side surface of the completed tatami floor, and the tatami mat was attached by sticking the front end of the tatami surface to the back surface of the tatami floor 12. In addition, the manufacturing method of a tatami surface is the same as that of the thing of Example 1 mentioned above.

  Moreover, except that the acrylic resin was not applied and impregnated at the inclined portion forming position of the wood fiber board obtained as a comparison, a placing tatami was produced in the same manner as in the above example. It was found that there was a possibility that the inclined part could easily be dented and damaged when riding on a wheelchair on the inclined part because the dent amount of the inclined part of the tatami floor measured under the same conditions exceeded 1 mm.

[Example 3]
After wet forming, 95% by weight of fiber obtained by digesting wood chips at high temperature and high pressure, 5% by weight of poval resin as a binder component, and adding necessary papermaking aids such as sizing agents to these, By drying, a wood fiber board (insulation board) having an apparent density of 0.24 g / cm ³ and a thickness of 15 mm was obtained.

Subsequently, the obtained wood fiber board was set as it was in a mold provided with an inclined surface for forming an inclined portion having a predetermined shape, and hot-pressed at 180 ° C. for 3 to 4 minutes. Thereby, the tatami floor in which the slope part compressed so that the height of an end surface is 1 mm and an apparent density might be 0.72 g / cm < ³ > was completed in the one side part of the wood fiber board.

  Here, with respect to the inclined part of this tatami floor, using an autograph (precision universal testing machine), the amount of dent (mm) when a surface load of 100 kgf (980 N) is applied in a 5 cm square range is measured. As a result, since the dent amount is less than 1 mm, there is no possibility that the inclined portion is easily recessed even if the inclined portion is ridden with a wheelchair.

  Then, the tatami mat was completely covered with the tatami surface from the surface to the side surface of the completed tatami floor, and the tatami mat was attached by sticking the front end of the tatami surface to the back surface of the tatami floor 12. In addition, the manufacturing method of a tatami surface is the same as that of the above-mentioned Example 1.
