Description

  The present invention relates to a tatami flooring material using a tatami mat.

  Tatami mats have been widely used as traditional flooring materials for Japanese houses, but recently, with the westernization of houses, floors with wooden flooring (such as wooden flooring) have become increasingly common. ing. For this reason, tatami rooms are decreasing.

  However, after the construction of the house, for example, in a room with wooden flooring, there are still many people who want to feel the feel of tatami mats, and there are many people who renovate part or all of the wooden flooring floor with tatami mats. .

  As described above, there are many requests for the taste of tatami even in the western world, and in order to meet the demands of such users, various techniques for enabling the use of tatami as a flooring material have been proposed. (For example, Patent Document 1 and Patent Document 2).

  Patent Document 1 discloses a tatami flooring material for enabling use of tatami as a flooring material, and Patent Document 2 discloses a tatami enclosure for enabling use of tatami as a flooring material. Yes.

  FIG. 13 is a diagram for explaining a flooring tatami 800 disclosed in Patent Document 1. In FIG. FIG. 14 is a view for explaining a tatami enclosure 900 disclosed in Patent Document 2. As shown in FIG.

  The tatami mat 800 for flooring disclosed in Patent Document 1 enables the tatami mat to be used as a flooring material, so that the tatami mat can be made thin and light, and has a high bending strength. It is said that a part or all of the wooden flooring floor can be tatami mat. In particular, when the flooring tatami 800 is thin, when a part of the room is a tatami floor, the level difference from the flooring can be reduced. Here, it is possible to reduce the thickness and weight and to obtain a high bending strength by using a laminated molded product in which a fiber reinforced thermoplastic resin sheet is welded to the surface of a foamed resin body as a core material. Because.

  On the other hand, in the tatami enclosure 900 disclosed in Patent Document 2, when a part of the flooring floor is a tatami mat, each tatami is moved by enclosing a plurality of tatami 920 with the frame 910. The size of the frame 910 can be freely adjusted according to the number of tatami mats and how to lay the tatami mats.

Utility Model Registration No. 3038942 JP 2001-123644 A

  The tatami mat 800 for flooring disclosed in Patent Document 1 has a tatami edge (tatami mat) as apparent from FIG. 13, and looks almost the same as a general tatami mat. For this reason, when the tatami 800 is laid between the oceans, the same tatami as a general tatami is laid in the construction of the ocean, and the harmony of the entire room may be lost. Further, the flooring tatami 800 disclosed in Patent Document 1 is not particularly devised in the case where a part of the room is a tatami mat. That is, when a part of the room (for example, the central part of the room) is a tatami mat, it is necessary to devise measures for preventing the individual tatami from moving. Such a device is not mentioned in the tatami mat 800 for flooring.

  On the other hand, the tatami enclosure 900 disclosed in Patent Document 2 can enclose a plurality of tatami mats with the frame body 910, so that the tatami mat surrounded by the frame body 910 can be fixed. In some cases, the presence of the frame body 910 may be an obstacle.

  Further, since the frame 910 is formed by mixing cellulose fine particles and a resin and melting them, the frame 910 has a completely different texture from that of the tatami mat and may give an uncomfortable appearance. Moreover, since the frame body 910 formed in this way is a material harder than a tatami mat, when a toe of a foot is hit against the frame body 910, a considerable pain is given to the toe.

  In this way, in either case, it is difficult to create an atmosphere similar to that of general wooden flooring materials in either case. The fact is that it only stayed at the level of "only part of the tatami mat was laid."

  When laying tatami on a part or all of the western part, many people want to keep the atmosphere of the western part. For this reason, the flooring tatami 800 disclosed in Patent Document 1 and the tatami enclosure 900 disclosed in Patent Document 2 cannot satisfy the demand.

  Incidentally, in the tatami mat 800 for flooring disclosed in Patent Document 1 and the tatami enclosure 900 disclosed in Patent Document 2, the size of the tatami mat is not the gist of each invention. Here, there are various sizes of conventional tatami mats such as Edo size, Kyoto size, housing estate size, etc. Basically, the width is 3 scales (about 900mm) and the length is 6mm. Generally, a scale (about 1800 mm) is used. Of course, in addition to these sizes, for example, there are also squares of 900 mm × 900 mm, etc., but in order to manufacture these tatami mats, the “I-grass” used as a raw material for the tatami table is at least about 1000 mm. Length is needed.

  However, since rush grass is a natural material, not all of the cut rush grass has a length of 1000 mm or more. The actual situation is that the percentage of grass is short.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a tatami flooring material that can taste the feel of a tatami without impairing the atmosphere between the oceans, and that can effectively use the cut “bush”.

  [1] The tatami flooring material of the present invention is a tatami flooring material in which a tatami mat is attached to a core material as a tatami floor, and the lateral side and the vertical side of the tatami flooring material and the core material. Of these, when the side along the direction of the length of the grass used in the tatami mat is defined as the side in the horizontal direction, the tatami flooring material has the length and length in the horizontal direction of the tatami flooring material. The length of at least the side in the horizontal direction is in the range of 800 mm to 200 mm, the thickness is in the range of 30 mm to 10 mm, and the tatami mat has an upper surface of the core material, Covers a lateral end surface along the lateral side of the core material, a longitudinal end surface along the longitudinal side of the core material, and a belt-like tatami mat bonding margin formed at the peripheral edge of the lower surface of the core material. It is affixed on the said core material.

  According to the tatami flooring material of the present invention, the upper surface of the core material is covered with the tatami surface and the peripheral surface of the lower surface is covered with the tatami surface, so that the cut surface of the tatami surface does not appear where it is conspicuous. Thereby, since it is not necessary to provide the tatami edge (tatami mat) provided in the general tatami mat, the atmosphere between the oceans can be kept intact. Moreover, since the horizontal length of the tatami flooring material is set to 800 mm to 200 mm, it is possible to use a non-conforming length of rush grass and to effectively use the cut rush grass. be able to.

  Moreover, the thickness of the tatami flooring material is 30 mm to 10 mm. By setting the thickness of the tatami flooring material to such a thickness, it can be handled in substantially the same manner as a general wooden flooring material. In addition, it is more preferable that the thickness of the tatami flooring material is 20 mm or less. When the thickness of the tatami flooring material is set to 20 mm or less, when using a plurality of tatami flooring materials of the present invention in a predetermined range of a room, the step difference from the original floor material should be reduced. Can do.

  [2] In the tatami flooring material of the present invention, the length of the side of the core material in the horizontal direction is α, the length of the side of the core material in the vertical direction is β, and the thickness of the core material is γ. When the bonding width of the tatami mat to be bonded at the margin of the tatami mat is δ, the lateral length of the tatami mat in a state where the tatami mat is unfolded has a length of approximately α + 2γ + 2δ, and the tatami mat is unfolded. The length of the tatami mat in the vertical direction is approximately β + 2γ + 2δ, and the length of the tatami mat in the lateral direction is the length obtained by adding the adhesive width δ of the tatami mat to the thickness γ of the core material. Are the laterally extending portions that extend in two opposite directions in the lateral direction, and of the longitudinal length of the mat surface, the thickness γ of the core material is equal to the bonding width δ of the mat surface. The portion corresponding to the length added with each of the vertical lengths extending in two opposite directions in the vertical direction. When the direction extending portion is used, it is preferable that a predetermined range including at least a part of a common portion of the lateral extending portion of the tatami mat and the longitudinal extending portion of the tatami mat is cut off.

  By setting the dimensions of the tatami mat (the length in the horizontal direction and the vertical direction) as described above, the tatami mat can cover the upper surface of the core material and cover the end surface to the peripheral edge of the lower surface. In addition, at least a part of the common portion of the laterally extending portion and the longitudinally extending portion of the tatami surface is cut off, so that the laterally extending portion and the longitudinally extending portion are folded at the corners of the core material. It is possible to easily carry out the “corner bending process” such as overlapping.

  Note that “approximately the length of α + 2γ + 2δ” means that a range of ± 20 mm is allowed for the length of α + 2γ + 2δ. Similarly, “approximately the length of β + 2γ + 2δ” means that a range of ± 20 mm is allowed for the length of β + 2γ + 2δ. .

  [3] In the tatami flooring material of the present invention, it is preferable that the core material is formed with chamfers corresponding to the thickness of the two tatami mats at each corner of the four corners of the core material.

  By forming such a chamfered portion, when the corner portion is folded such that the tatami mat is folded at the chamfered portion, the bulge of the tatami mat is absorbed. Can do. That is, in the chamfered portion, when, for example, three tatami mats overlap each other, the thickness of two tatami mats is an extra thickness, but a chamfer corresponding to the thickness of about two tatami mats is formed. Thus, the thickness of about two tatami mats generated by folding by the chamfered portion can be absorbed. As a result, each side on the upper surface side of the tatami flooring material is substantially straight from end to end on each side, so in the state where the laying process is completed, each adjacent tatami flooring material is Can be laid without gaps. Note that “equivalent to the thickness of two tatami mats” is within the range of 3 mm to 4 mm when the thickness of the tatami mat is 1.5 mm to 2 mm.

  [4] In the tatami flooring material of the present invention, the planar shape of the tatami flooring material is preferably a strip shape.

  Since the tatami flooring material has a strip shape, the tatami flooring material has a shape similar to a general wooden flooring material, and therefore can be handled in the same manner as a general wooden flooring material.

  [5] In the tatami flooring material of the present invention, it is preferable that the side length of the tatami flooring material is about 600 mm, and the length of the vertical side is about 150 mm.

  By setting the strip-shaped tatami flooring material to such a size, it can be handled in the same manner as a general wooden flooring material, and the laying work can be performed in substantially the same manner as a general wooden flooring material. Moreover, even when the tatami flooring material of the present invention is laid, for example, in the ocean, the atmosphere between the oceans can be maintained by making the mat flooring material into a strip shape having such a size.

  The horizontal side length is set to “approx. 600 mm” and the vertical side length is set to “approx. 150 mm”, which can be used for Kyoto, Chukyo, Edo, and housing estate sizes. This is because. Here, “about 600 mm” is in the range of 550 mm to 650 mm, and “about 150 mm” is in the range of 140 mm to 160 mm.

  [6] In the tatami flooring material of the present invention, it is also preferable that the planar shape of the tatami flooring material is a square shape.

  Thus, the tatami flooring material may be square, and even in such a shape, it can be handled in the same manner as a general wooden flooring.

  [7] In the tatami flooring material of the present invention, it is preferable that the lateral side length and the longitudinal side length of the tatami flooring material are about 450 mm or about 300 mm, respectively.

  By setting the square-shaped tatami flooring material to such a size, it can be handled in the same manner as a general wooden flooring material made of wood, and the laying work can be performed in substantially the same manner as a general wooden flooring material. Further, by making the tatami flooring material a square having such a size, even when the tatami flooring material of the present invention is laid, for example, in the ocean, the atmosphere between the oceans can be maintained.

  In this case, the size of the square tatami flooring material (size of one side) is set to “about 450 mm” or “about 300 mm”, which corresponds to the Kyoto size, Chukyo size, Edo size, housing estate size, etc. This is because. Here, “about 450 mm” is in the range of 420 mm to 480 mm, and “about 300 mm” is in the range of 280 mm to 320 mm.

  [8] In the tatami flooring material of the present invention, it is preferable that the core member has an inclined surface in which the lateral end surface and the longitudinal end surface are inclined inward from the upper surface toward the lower surface.

  By setting it as such a structure, in the state which laid construction was complete | finished, each adjacent tatami flooring material will be in the state laid without gap in appearance. That is, the lateral end face and the longitudinal end face (also referred to as each end face) of the core material are inclined surfaces that inwardly incline from the upper surface to the lower surface of the core material, so that the tatami mat flooring material also has the tatami mat. Each end surface of the flooring material becomes an inclined surface inclined inward. For this reason, adjacent tatami flooring materials are brought into contact not by “surface contact” between end surfaces but by “line contact” between sides on the upper surface side.

  Thereby, a clearance gap becomes difficult to stand out in each adjacent tatami flooring material. This is because if adjacent tatami flooring materials are in contact with each other by surface contact, a gap is likely to occur due to the slight bulge of the tatami mat surface existing on each end surface of the tatami flooring material. This is because when the tatami flooring material to be touched is in contact by line contact between the sides on the upper surface side, it is difficult to be affected by such influence.

  [9] In the tatami flooring material of the present invention, it is preferable that a cushion material is interposed between the upper surface of the core material and the tatami surface.

  By setting it as such a structure, after laying a tatami flooring material, the touch when walking or sitting can be made comfortable.

  [10] In the tatami flooring material of the present invention, a convex pedestal portion that is substantially the same as the thickness of the tatami mat or slightly thicker than the thickness of the tatami mat is provided in a predetermined range on the lower surface of the core member that is separated from the margin of the mat mat. Preferably it is formed.

  By adopting such a configuration, the lower surface of the tatami flooring material (the contact surface with the flooring material) can be made substantially flat, and when the tatami flooring material is bonded to the flooring material, the tatami flooring material is securely bonded. can do. Further, even when the tatami flooring material is simply laid without adhering it to the flooring material, the tatami flooring material can be laid flat.

  [11] In the tatami flooring material of the present invention, it is preferable that the convex pedestal portion is an attachment plate bonded to the core material.

  By forming the pedestal by sticking the attachment plate in this way, it is possible to provide flexibility in the order of the manufacturing process of the tatami flooring material. For example, when there is a process that is easier to work in a state where the attached plate is not attached, it is possible to attach the attached plate after performing the process.

  [12] In the tatami flooring material of the present invention, the convex pedestal portion is preferably formed integrally with the core material.

  With such a configuration, it is not necessary to prepare a separate member for forming the pedestal portion, and the process for forming the pedestal portion can be eliminated.

  [13] In the tatami flooring material of the present invention, an anti-slip member is preferably provided on the lower surface of the core material.

  By adopting such a configuration, even when a plurality of tatami flooring materials of the present invention are laid in a predetermined range of a part of a room, it can be laid without providing a frame or the like. For this reason, it is not necessary to have a professional contractor perform the construction, and the tatami flooring material can be easily laid in a favorite space.

  [14] In the tatami flooring material of the present invention, the anti-slip member is a sheet-like member having an anti-slip effect, and the planar shape of the sheet-like member corresponds to the shape of the tatami flooring material. The length in the horizontal direction and the length in the vertical direction are equal to or less than the length in the horizontal direction and the length in the vertical direction of the tatami flooring material, and the horizontal side and the length in the vertical direction of the tatami flooring material. It is preferable that the tatami flooring material is attached to the lower surface of the tatami flooring material so as to protrude from the side by a predetermined length.

  With such a configuration, when the tatami flooring material of the present invention is laid so that the tatami flooring materials are adjacent to each other, the protruding portions of the respective anti-slip sheets (adjacent sides and vertical sides) in the adjacent tatami flooring material It is possible to eliminate the fact that the portions protruding from the sides in the direction overlap each other. Thereby, when the tatami flooring material of the present invention is laid so as to cover a predetermined range of a part of the room, the entire laying range can be flattened without causing a step due to the overlap of the non-slip sheets.

  Hereinafter, embodiments of the present invention will be described.

[Embodiment 1]
FIG. 1 is a perspective view illustrating an appearance of a tatami flooring material 100 according to the first embodiment.
FIG. 2 is a view of the tatami flooring material 100 according to the first embodiment as viewed from each direction. 2A is a plan view when the upper surface 101a of the tatami flooring material 100 shown in FIG. 1 is viewed along the z axis, and FIG. 2B is a plan view of the tatami flooring material 100 shown in FIG. FIG. 2C is a cross-sectional view taken along line y, FIG. 2C is a cross-sectional view taken along line xx of the tatami flooring material 100 shown in FIG. 1, and FIG. 2D is tatami flooring material 100 shown in FIG. It is a top view at the time of seeing the lower surface 101b (it is also called the back surface 101b) of z along az axis.

  As shown in FIGS. 1 and 2, the tatami flooring material 100 includes a core material 110 as a tatami floor, a cushion material 120 attached to an upper surface 111a (see FIG. 3) of the core material 110, and a core material. 110 includes a base plate 130 as a pedestal attached to the lower surface 111b (see FIG. 4D) of the 110 and a tatami surface 140.

  When the tatami flooring material 100 is viewed along the z-axis, the side in the direction along the x-axis when the upper surface 101a of the tatami flooring material 100 is viewed is defined as the lateral sides 102a and 102b of the tatami flooring material 100. When the top surface 101a of the tatami flooring material 100 is viewed along the z-axis 100, the sides in the direction along the y-axis are defined as the vertical sides 102c and 102d of the tatami flooring material 100. However, since the tatami flooring material 100 according to the first embodiment has a strip shape that is long in the horizontal direction, the horizontal sides 102a and 102b are “long sides 102a and 102b”, and the vertical sides 102c and 102d are “short sides”. 102c, 102d ".

  Further, the lateral sides 102 a and 102 b (long sides 102 a and 102 b) and the vertical sides 102 c and 102 d (short sides 102 c and 102 d) are assumed to be sides on the upper surface 101 a side of the tatami flooring material 100.

  The tatami mat table 140 is manufactured by Reed grass (hereinafter, referred to as “Isa”), and the core material is such that the length direction of the Reed grass is along the long side (side along the x axis). 110 is attached. Further, as shown in FIGS. 2A to 2D, the tatami mat table 140 includes an upper surface 111a (see FIGS. 3 and 4) of the core material 110 and end surfaces 112a to 112d of the core material 110 (FIGS. 3 and 4). 4) is attached to the entire periphery of the peripheral portion of the lower surface 111b (see FIGS. 3 and 4) of the core member 110.

  As for the dimensions of the tatami flooring material 100 thus configured, the long side length L1 is 600 mm, the short side length (also referred to as width) L2 is 150 mm, and the thickness T1 is 17 mm. Here, the size with a long side length L1 of 600 mm and a short side length L2 of 150 mm is a standard size of a floor plan in a house in Japan (for example, 1 / n of 1800 mm (where n is a natural number) Therefore, it is convenient in various aspects such as ease of construction.

  As the core material 110, a material obtained by compressing and molding a material obtained by finely pulverizing wood can be used, but the material of the core material 110 is not particularly limited. However, a material that is easy and lightweight, such as cutting, is not easily corroded, and is less likely to be warped or twisted.

FIG. 3 is a perspective view of the core member 110.
FIG. 4 is a diagram illustrating a case where the core member 110 is viewed from each direction. 4A is a plan view when the upper surface 111a of the core member 110 shown in FIG. 3 is viewed along the z axis, and FIG. 4B is an end surface 112a of the core member 110 shown in FIG. 4C is a side view when viewed along the y-axis, and FIG. 4C is a side view when the end surface 112c of the core member 110 shown in FIG. 3 is viewed along the x-axis, and FIG. These are top views at the time of seeing the lower surface 111b of the core material 110 shown in FIG. 3 along az axis. Also in the core material 110, the lateral sides 116 a and 116 b of the core material 110 may be expressed as “long sides” and the vertical sides 116 c and 116 d of the core material 110 may be expressed as “short sides”. is there. It is assumed that the lateral sides (long sides) 116 a and 116 b and the longitudinal sides (short sides) 116 c and 116 d of the core member 110 are sides on the upper surface side of the core member 110.

  The length α of the long sides 116a and 116b and the length β of the short sides 116c and 116d of the core 110 are the dimensions of the tatami flooring material 100 (the length of the long sides 102a and 102b is 600 mm and the length of the short sides 102c and 102d). 150 mm), the thickness of the tatami surface 140 is reduced by about 1.5 mm to 2 mm.

  Specifically, assuming that the thickness of the tatami mat table 140 is 2 mm, the length α of the long sides 116a and 116b of the core is about 596 mm, and the length β of the short sides 116c and 116d of the core is about 146 mm. is there. Further, the thickness γ of the core material 110 is the thickness of the tatami flooring material 100 (17 mm), the thickness of the tatami mat 140, the thickness of the cushion material 120 (about 2 mm), and the thickness T2 of the accessory plate 130 (about 2 mm). It is getting smaller by the minute. That is, if the thickness of the tatami mat 140 is 2 mm, the thickness of the cushion material 120 is 2 mm, and the thickness of the accessory plate is 3 mm, the thickness γ of the core material 110 is about 10 mm.

  The core member 110 has an inverted trapezoidal shape when the end surfaces 112a to 112d of the core member are viewed along the y-axis and the x-axis (FIGS. 2B, 2C, and 4). (See (b) and (c).) That is, the core material 110 has an area of the lower surface 111b smaller than the area of the upper surface 111a, and the end surfaces 112a to 112d of the core material 110 are inclined surfaces that incline inward as they go from the upper surface to the lower surface. It has become.

  Accordingly, an angle θ1 (see FIGS. 2B and 2C and FIGS. 4B and 4C) formed by the upper surface 111a of the core member 110 and each of the end surfaces 112a to 112d becomes an acute angle. θ1 is preferably about 80 degrees. Of the four end surfaces 112a to 112d of the core member 110, the end surfaces 112a and 112b may be referred to as “lateral end surfaces 112a and 112b”, and the end surfaces 112c and 112d may be referred to as “vertical end surfaces 112c and 112d”.

  Since the end surfaces 112a to 112d of the core material 110 are inclined as described above, the end surfaces 103a and 103b and the end surfaces 103c and 103d of the tatami flooring material 100 are also the same as the end surfaces 112a to 112d of the core material 110. It becomes an inclined surface. In the tatami flooring material 100, the end surfaces 103a and 103b of the tatami flooring material 100 may be referred to as “lateral end surfaces 103a and 103b”, and the end surfaces 103c and 103d may be referred to as “vertical end surfaces 103c and 103d”.

  Further, as shown in FIG. 4, the core material 110 corresponds to the thickness of approximately two sheets of the tatami mat 140 at each corner of the four corners of the core material 110 (both ends of the lateral end surfaces 112 a and 112 b). A chamfered portion 113 is formed.

  The chamfered portion 113 is notched obliquely at an angle of about 5 degrees toward the longitudinal end surfaces 112c and 112d of the core member 110 starting from a position of about 30 mm to 40 mm from each end of the lateral end surfaces 112a and 112b. Formed by. As a result, both ends of the long sides 116a and 116b of the core member 110 are cut out by c1 in the vertical direction (direction along the y-axis). For this reason, the widths of the short sides 116c and 116d of the core member 110 are narrowed accordingly. In addition, c1 shall be 3 mm-4 mm, and this 3 mm-4 mm is equivalent to the thickness for two sheets of the tatami mat table 140.

  The reason for providing such a chamfered portion 113 is as follows. That is, when the tatami surface 140 is attached to the core material 110, a “corner bending process” is performed such that the tatami surface 140 is folded at each corner of the core material 110. This is to prevent bulging due to the thickness of the tatami mat surface 140 when the “bending process” is performed and the linearity of the edges (edges) of the tatami flooring material 100 from being lost. The “corner bending process” performed at the corner of the core 110 will be described later.

  Further, as shown in FIG. 4B to FIG. 4D, an attachment plate 130 as a pedestal is attached to the lower surface 111 b of the core member 110. The accessory plate 130 is affixed to the lower surface 111b of the core material 110 so as to leave a strip-shaped blank portion 115 over the entire periphery of the peripheral surface of the lower surface 111b of the core material 110. Thus, a step corresponding to the thickness T2 of the attachment plate 130 (see FIGS. 4B and 4C) is formed between the blank portion 115 and the attachment plate 130 on the lower surface 111b of the core member 110. The The margin portion 115 is used as a “tatami surface adhesion margin” for adhering the tatami mat surface 140, and an adhesion width δ (see FIG. 2D) of the tatami surface 140 at the “tatami mat surface adhesion margin” is about 30 mm. .

  Further, the thickness T2 of the attachment plate 130 is the same as or slightly thicker than the thickness of the tatami surface 140. Accordingly, when the tatami surface 140 is bonded to the blank portion 115, the entire lower surface side of the tatami flooring material 100 is substantially flush or the surface of the support plate 130 (contact surface with the floor plate) slightly protrudes. When the flooring material 100 is bonded to a floor board (not shown) with an adhesive, the attachment board 130 and the floor board can be bonded in a state in which they are in reliable contact.

5 and 6 are views for explaining the manufacturing process of the tatami flooring material 100.
First, the core material 110, the cushion material 120, and the tatami surface 140 are prepared. As described above, the tatami surface 140 is attached to the core member 110 so that the height direction of “Isa” is the direction along the long side of the tatami flooring material 100 (the direction along the x axis).

  In this case, since the length of the tatami flooring material 100 is set to 600 mm, the length of the “bush” used for manufacturing the tatami surface 140 is about 700 mm including the bent portion of the tatami surface 140. It is enough. By the way, a typical tatami mat has a width of about 900 mm, so the length of the rush must be at least about 1000 mm, and shorter rushes are incompatible with the production of a typical tatami. May be discarded.

  On the other hand, in the tatami flooring material 100, even the grass that is considered to be such a non-conforming product can be sufficiently used if it has a length of about 700 mm. For this reason, in the tatami flooring material 100, rush can be used effectively.

  Hereinafter, the manufacturing process of the tatami flooring material 100 will be described with reference to FIGS. 5 and 6.

  An adhesive (not shown) is applied to the top surface 111a of the prepared core material 110, and the cushion material 120 is attached to the core material 110 to which the adhesive has been applied (see FIG. 5A). FIG. 5A is a side view of the end surface 112a of the core member 110 viewed along the y-axis.

  Next, the cushion material 120 side of the core material 110 to which the cushion material 120 is attached is positioned on the tatami surface 140 so as to contact the back surface of the tatami surface 140 (see FIG. 5B). FIG. 5B and FIG. 5C described below are plan views showing a state in which the tatami mat table 140 is arranged on the upper side of the core member 110. At this time, the tatami mat table 140 may be cut in advance to have a predetermined dimension, or may be cut to have a predetermined dimension after the core material 110 is attached. . In any case, the tatami mat table 140 has such a size that an extended portion of about 40 mm can be formed from the long sides 116 a and 116 b and the short sides 116 c and 116 d of the upper surface 111 a of the core member 110.

  Specifically, the length of the long sides 116a and 116b of the core material 110 is α, the length of the short sides 116c and 116d of the core material 110 is β, the thickness of the core material 110 is γ, and the mating surface is bonded ( When the bonding width of the tatami mat to be bonded in the blank portion 115) is δ, the lateral length L3 of the tatami mat 140 in a state in which the tatami mat 140 is expanded is approximately α + 2γ + 2δ, and the vertical length of the tatami mat 140 is The length L4 is approximately β + 2γ + 2δ.

  Note that “approximately the length of α + 2γ + 2δ” means that a range of ± 20 mm is allowed for the length of α + 2γ + 2δ. Similarly, “approximately the length of β + 2γ + 2δ” means that a range of ± 20 mm is allowed for the length of β + 2γ + 2δ.

  By setting the tatami mat table 140 to such dimensions, the tatami mat table 140 has the adhesive width δ of the tatami mat table 140 equal to the thickness γ of the core member 110 out of the longitudinal length L4 of the tatami mat table 140 when the tatami mat table 140 is expanded. The added length (γ + δ) extends from the two long sides 116a and 116b of the core member 110 in two opposite directions in the longitudinal direction (direction along the y-axis). Further, the tatami mat 140 is the core material by a length (γ + δ) obtained by adding the adhesive width δ of the tatami mat 140 to the thickness γ of the core mat 110 among the lateral length L3 of the tatami mat 140 when the tatami mat 140 is expanded. 110 extend from the two short sides 116c and 116d in two opposite directions in the lateral direction (the direction along the x axis).

  Here, the extending portions extending in the vertical direction (the direction along the y-axis) are referred to as the vertical extending portions 141a and 141b, and the extending portions extending in the horizontal direction (the direction along the x-axis), respectively. Are laterally extending portions 141c and 141d. In FIG. 5B, a gray portion indicates a common portion 142 of the longitudinally extending portions 141a and 141b and the laterally extending portions 141c and 141d. The common portions 142 are respectively present at the four corners of the expanded tatami table 140.

  Next, in the state of FIG. 5B, the predetermined ranges at the four corners of the tatami mat 140 in the expanded state (the predetermined range including at least a part of the common portion 142) are cut out as unnecessary portions (see FIG. 5C). ). In the tatami flooring material 100 according to the first embodiment, unnecessary portions are cut by cutting in a direction along the long side (direction along the x-axis) and a direction along the short side (direction along the y-axis). At this time, in the direction along the long side, a cut is made along the cutting line H1 that is parallel to the x-axis, and in the short side direction (y-axis direction), a predetermined angle θ2 (θ2 is the angle with respect to the cutting line H1). It cuts along the cutting line H2 which makes about 110 degrees. Note that such unnecessary portions can be removed by pressing or the like.

  At this time, among the intersections P11, P112, P13, and P14 of the cutting line H1 and the cutting line H2, the distance between the intersection P11 and the intersection P12 and the distance between the intersection P13 and the intersection P14 (referred to as L5, respectively). Is substantially the same as the length α of the long sides 116a and 116b of the core material 110, and the distance between the intersection point P11 and the intersection point P13 and the distance between the intersection point P12 and the intersection point P14 (referred to as L6 respectively) are short sides of the core material 110. A length obtained by adding the thickness γ of the core material 110 to the length β of 116c and 116d is preferable. 5B and 5C, the length (γ + δ) obtained by adding the adhesive width δ of the tatami mat 140 to the thickness γ of the core member 110 is the length of the long sides 116a and 116b and the short sides 116c and 116d. It is drawn with a little exaggeration.

  Next, the longitudinally extending portions 141a and 141b and the laterally extending portions 141c and 141d of the tatami surface 140 are bent along the end faces 112a to 112d of the core member 110, and the lower surface (back surface) 111b side of the core member 110 A folding process is carried out to be caught in the cable. This bending process will be described with reference to FIG. Note that FIG. 6 illustrates a bending process at one corner (the corner between the end surface 112a and the end surface 112c) of the four corners of the core member 110 when the bending process is performed. FIG.

First, after applying an adhesive to each bonding portion between the tatami surface 140 and the core material 110, the laterally extending portion 141 c of the tatami surface 140 is short on the longitudinal end surface 112 c of the core material 110 as shown in FIG. The side 116c is bent as a crease.
Then, after extending the laterally extending portion 141c along the end surface 112c of the core member 110, as shown in FIG. 6B, the lower end 117c on the lower surface side of the longitudinal end surface 112c of the core member 110 is bent. Then, the laterally extending portion 141c is press-contacted along the blank portion 115 (see FIG. 4D) as “Tatami surface bonding margin” on the lower surface (back surface) 112b of the core member 110. At this time, since the adhesive is applied to each bonding portion between the tatami surface 140 and the core material 110, the laterally extending portion 141c of the tatami surface 140 is bonded to the core material 110 in the state of FIG. 6B. It becomes a state.

  In the state of FIG. 6B, the tatami surface 140 has a protruding portion K (see FIG. 6B) formed at the end of the longitudinal end surface 112 c of the core member 110. By the way, when folding the tatami surface 140, steam is sprayed on the tatami surface 140 to bend. The reason why steam is sprayed is to make the tatami surface 140 soft and easy to bend.

  Next, as shown in FIG. 6C, the longitudinally extending portion 141 a of the tatami surface 140 is replaced with the long side 116 a on the end surface 112 a of the core member 110, as in the case of the laterally extending portion 141 c of the tatami surface 140. The lower side 117a is bent along the long side 117a. At this time, since the protruding portion K is formed in the tatami surface 140, a “corner portion bending process” is performed in which the tatami surface of the protruding portion K is folded while being folded so that the protruding portion K is folded inside. After extending along the end surface 112a of the core member 110 at the longitudinally extending portion 141a of the tatami mat surface 140, it is press-contacted along the blank portion 115 as the “adhesion margin for the tatami surface” on the lower surface 111b of the core member 110. At this time, since the adhesive is applied to each bonding portion between the tatami surface 140 and the core material 110, the longitudinally extending portion 141a of the tatami surface 140 is bonded to the core material 110 in the state of FIG. 6C. It becomes a state.

  By performing a series of bending processes as shown in FIGS. 6A to 6C, the tatami table 140 is folded at the corners of the end face 112c and the end face 112a as shown in FIG. 6C. Become. Although it is difficult to understand in FIG. 6C, the tatami table 140 is in a state where three tatami mats are partially overlapped (a state where the tatami mats are folded in triplicate) at the corners of the end surfaces 112c and 112a.

  As described above, when the tatami mat is folded in triplicate, the portion that is folded in triplicate is thicker by two tatami mats than other portions (location of one tatami mat). The thickness of the two tatami mats appears as a bulge of the long side 102a of the tatami flooring material 100, and the linearity of the long side of the tatami flooring material 100 is lost.

  However, in the tatami flooring material 100 according to the first embodiment, the linearity of the long side 102a can be maintained. This is because, as described in FIGS. 3 and 4, the chamfered portion 113 corresponding to the thickness of two tatami mats is present in the corner portion (end portion of the end surface 112 a) of the core member 110. This is because 113 absorbs the thickness generated by folding the tatami surface 140.

  In addition, although FIG. 6 (a)-FIG.6 (c) were description about one corner | angular part of the four corner | angular parts of the core material 110, it implements similarly in another corner | angular part. be able to.

  By the way, in the process of bending the tatami mat table 140 as described above, it is possible to manually perform all the processes shown in FIGS. 5 and 6. However, all or a part of each process is performed by a dedicated machine (not shown). Can also be used.

  FIG. 7 is a diagram shown for explaining an example of construction when the tatami flooring material 100 is laid in the room 300. Fig.7 (a) is a figure which shows the state in the middle of construction, FIG.7 (b) is a figure which shows the state which construction was complete | finished. FIG. 7 is a diagram showing the room 300 in a plan view, and the room 300 is generally made in a Western style, and when the area is replaced with the size of a tatami mat, it is about 4 tatami halves. Suppose it is wide.

  Moreover, in the case of FIG. 7, it demonstrates as what lays the tatami flooring material 100 from the beginning of construction of a house, for example. For this reason, the tatami flooring material 100 is laid on a floor base material (such as plywood). In addition, in FIG. 7, illustration of the doorway of a room etc. is abbreviate | omitted.

  As described above, the size of the tatami flooring material 100 used here is 600 mm for the long side and 150 mm for the short side. In order to lay such a tatami flooring material 100 in the room 300, the corner of the room 300 (for example, the upper left corner in FIG. 7) is similar to a general wooden flooring material in the tatami flooring material 100. The short side 102c is brought into contact with the wall surface 310a and the long side 102b is brought into contact with the wall surface 310b, and then laid along the x-axis.

  At this time, if the length of the last tatami flooring material 100 in one row is excessive, the excess length portion (1/2 length (300 mm)) is cut and cut. Next, 300 mm of tatami flooring material is sequentially laid so as to be the head of the next row (2 rows) (see FIG. 7A). By repeating such a process, the tatami flooring material 100 can be laid in the entire room 300 (see FIG. 7B). In addition, since the tatami flooring material 100 is comprised by the tatami surface 140 and the core material 110 which uses a timber as a raw material, it can be cut | disconnected easily similarly to a general wooden flooring material.

  When the tatami flooring material is sequentially laid as described above, in the final row (16 rows), a space (for example, 70 mm) smaller than the length (150 mm) of the short side of the tatami flooring material between the wall surface 310d. In such a case, the tatami flooring material 100 is cut and laid so that the width of the tatami flooring material 100 is 70 mm. The cutting process for reducing the width of the tatami flooring material 100 may be performed by cutting the tatami flooring material 100 along the long side.

  Moreover, in order to hide the cut surface of the cut | disconnected tatami flooring material in the location where the tatami flooring material 100 and each wall surface 310a-310d contact | abut, although illustration is abbreviate | omitted, each baseboard as finishing material (decorative material) is each shown. It is preferable to attach to the contact portion between the wall surfaces 310a to 310d and the tatami flooring material 100 over the entire circumference (excluding the entrance / exit).

  In this way, the tatami flooring material 100 can be laid in a manner similar to that of a general wooden flooring material. Further, as shown in FIG. 7, by arranging the tatami flooring materials 100 adjacent to each other in a row so as to be “deviation” by a predetermined length in the long side direction, the entire room can be obtained in a state where laying is completed. However, it is possible to make an alternate mosaic pattern in the same manner as general wooden flooring (see FIG. 7B).

  In addition, when the tatami flooring material does not remain in a certain row (for example, 1 row) and is just the length, the tatami flooring material is, for example, 1/2 at the head of the next row (2 rows). As described above, the length of the first tatami flooring material 100 in the adjacent row is alternately repeated as “normal length” and “1/2 length”, such as pasting a cut piece into In addition, it can be an alternating mosaic pattern.

  Further, in the construction example of FIG. 7B, the adjacent tatami flooring material 100 in each row is arranged so that “deviation” occurs by a length of ½ in the long side direction. Is not limited to ½, and the magnitude of “deviation” can be arbitrarily set. By doing in this way, an atmosphere closer to general wooden flooring can be given.

  FIG. 8 is a diagram for explaining a modification of the laying method. That is, in the construction example of FIG. 7 described above, the arrangement in a state in which the adjacent tatami flooring materials 100 in each row are displaced by a predetermined length (1/2 length) in the long side direction. However, without such an arrangement, as shown in FIG. 8, the arrangement is such that each short side (102c, 102d) of each tatami flooring material 100 is on the same straight line along the y-axis. It is also possible to construct it. In this case, when the tatami flooring material 100 is laid in the direction along the x-axis, if there is a remainder in the length of the tatami flooring material at the last stage of each row, the remaining portion is cut for each row. That's fine.

  As described above, the tatami flooring material 100 according to the first embodiment covers the upper surface 111a of the core material 110 by the tatami mat table 140 and extends from the end surfaces 112a to 112d of the core material 110 to the peripheral edge portion (margin portion 115) of the lower surface 111b. Is attached to the core material 110 so as to cover the tatami flooring material 100, the cut surface of the tatami mat surface 140 does not appear where it is conspicuous. For this reason, it is not necessary to provide a tatami edge (tatami mat), and it can be set as the tatami flooring material 100 which does not impair the atmosphere between the oceans.

  In addition, because the length of the side of the tatami flooring material 100 is 600 mm, it is possible to use non-conforming length of grass, and effectively use the cut grass. can do.

  Further, in the tatami flooring material 100, the short sides 102c and 102d are straight lines, and the long sides 102a and 102b are also substantially straight from one end to the other end of the long sides 102a and 102b. In addition, since the angle formed by the long sides 102a and 102b and the short sides 102c and 102d is a right angle, in the state where the laying is finished, the adjacent tatami flooring materials are not only the short sides but also the long sides. It will be in a state of being spread without gaps.

  As described above, the long side 102a, 102b is linear from one end to the other end, and the angle between the long side 102a, 102b and the short side 102c, 102d is a right angle as described above. As described above, the chamfered portions 113 formed at the four corners of the core 110 can absorb the bulge of the tatami mat that is generated by folding the tatami mat.

  In addition to the above-described reason, the tatami flooring material can be laid without causing a gap between adjacent tatami flooring materials. The end surfaces 112a to 112d of the core material 110 face the lower surface 111b from the upper surface 111a. This is because the inclined surface is inclined inward.

  As described above, the end surfaces 112a to 112d of the core member 110 are inclined surfaces that are inclined inwardly from the upper surface 111a toward the lower surface 111b, so that adjacent tatami flooring materials 100 are not "surface contact", Since “line contact” occurs between the sides, the tatami flooring material 100 can be laid without any gap between adjacent tatami flooring materials. That is, when adjacent tatami flooring materials are in contact with each other by surface contact at each end surface, a gap is likely to occur due to the slight bulge of the tatami surface existing on each end surface of the tatami flooring material, but adjacent to each other. It is because it is hard to receive such an influence, when contacting by the line contact by the edge | side of a tatami flooring material.

  Further, the tatami flooring material 100 is different from a general wooden flooring material in which each end face is subjected to uneven processing called real processing, and adjacent tatami flooring materials are fitted with unevenness. After laying, if only replacing the tatami flooring material at a specific location after laying, remove only the tatami flooring material to be replaced and lay a new tatami flooring material. Such repair work can be done easily.

[Embodiment 2]
In the first embodiment described above, the case where the tatami flooring material is spread over the entire room has been described. However, in the second embodiment, the tatami flooring material is laid in a part of the room (for example, a predetermined range in the center of the room). The case will be described.

  FIG. 9 is a view for explaining the tatami flooring material 200 according to the second embodiment. 9A is a plan view of the tatami flooring material 200 viewed from the upper surface 101a along the z axis, and FIG. 9B is a plan view of the tatami flooring material 200 viewed from the lower surface 101b along the z axis. FIG. 9C is a side view of the tatami flooring material 200 viewed from the end surface 103a along the y-axis.

  The tatami flooring material 200 has a configuration in which an anti-slip sheet 220 is attached to the back side of the tatami flooring material body 210 as an anti-slip member. The tatami flooring material body 210 has the same configuration as the tatami flooring material 100 described in the first embodiment. For this reason, the same parts as those of the tatami flooring material 100 are denoted by the same reference numerals.

  As shown in FIG. 9, the tatami flooring material 200 has an anti-slip sheet 220 attached to the back side of the tatami flooring material body 210 (tatami flooring material 100). As the non-slip sheet 220, for example, a sheet-like felt material subjected to anti-slip processing can be used. A commercially available felt material can be used.

  The non-slip sheet 220 has a shape corresponding to the tatami flooring material main body 210 (tatami flooring material 100), and the tatami flooring material 200 according to the second embodiment has a similar shape to the tatami flooring material main body 210 (tatami flooring material 100). I am doing. In the tatami flooring material 200, the lateral length L7 and the longitudinal length L8 of the anti-slip sheet 220 are the lateral length (about 600 mm) of the tatami flooring material body 210 (tatami flooring material 100) and It is assumed that the length is the same as the length in the vertical direction (about 150 mm). The thickness T3 of the anti-slip sheet 220 is not particularly limited as long as it does not significantly affect the thickness of the tatami flooring material 200, but is preferably 3 mm or less.

  By attaching the non-slip sheet 220 having such dimensions to the lower surface of the tatami flooring material main body 210 (the lower surface 101b of the tatami flooring material 100), the tatami flooring material 200 can be obtained. The anti-slip sheet 220 has two orthogonal sides (for example, the long side 102a and the short side 102d) among the four sides (long sides 102a and 102b and short sides 102c and 102d) of the upper surface 101a of the tatami flooring material body 210. Are attached to the lower surface 101b of the tatami flooring material 200 so as to protrude outward by a predetermined length ΔL (ΔL = about 15 mm to about 30 mm).

  For this reason, in the lower surface of the tatami flooring material 200, the area | region where the non-slip sheet | seat 220 is affixed exists. In addition, the area | region where the non-slip | skid sheet | seat 220 is affixed on the back surface of the tatami flooring material 200 will be called "the non-slip | skid sheet non-adhesion area | region 230".

  FIG. 10 is a diagram for explaining a method of laying the tatami flooring material 200. FIG. 10A is a diagram showing a case where two tatami flooring materials (the tatami flooring material 200A and the tatami flooring material 200B are limited to FIG. 10) are laid along the x-axis, and FIG. ) Is a diagram showing a case where two tatami flooring materials 200A and 200B are laid along the y-axis.

  As shown in FIG. 10A, when the tatami flooring materials 100A and 100B are laid along the x-axis direction, the short-side protruding portion of the anti-slip sheet (referred to as non-slip sheet 220A) in the tatami flooring material 200A. And the non-slip sheet non-adhering region (referred to as non-slip sheet non-adhering region 230B) in the tatami flooring material 200B are opposed to each other, and therefore the anti-slip sheet 220A of the tatami flooring material 100A and the tatami flooring material 100B. The non-slip sheet (referred to as the non-slip sheet 220B) does not overlap.

  Similarly, when laying the tatami flooring materials 100A and 100B so as to be adjacent to each other in the y-axis direction, the long-side protruding portion of the non-slip sheet 220A in the tatami flooring material 200A and the non-slip sheet non-sticking on the tatami flooring material 200B are also applied. Since the wearing area 230B faces each other, the anti-slip sheet 220A of the tatami flooring material 100A and the anti-slip sheet 220B of the tatami flooring material 100B do not overlap.

  Thereby, when the tatami flooring material 200 is laid so as to cover a predetermined range of a part of the room, the entire laying range can be made flat without causing a step due to the overlap of the non-slip sheets 220.

  FIG. 11 is a diagram showing a state in which a plurality of tatami flooring materials 200 are laid in a predetermined range of a part of the room 300. In FIG. 11, the long sides 102a and 102b of the tatami flooring material 200 are in the direction along the x axis, the short sides 102c and 102d are in the direction along the y axis, and three in the direction along the x axis. In the direction along the y-axis, a case where 12 sheets are laid is shown.

  By using the tatami flooring material 200 according to the second embodiment, a conventionally used enclosure frame (for example, the frame body 910 in FIG. 14) becomes unnecessary. This is because the anti-slip sheet 220 is provided on the back surface of the tatami flooring material 200.

  In addition, when laying the tatami flooring material 200 as shown in FIG. 11, in the tatami flooring material located at the tail in each of the x-axis direction and the y-axis direction, the anti-slip protruding from the long side 102a and the short side 102d Since the protruding portion of the sheet 220 remains exposed, it is preferable from an aesthetic viewpoint to cut the protruding portion of the anti-slip sheet.

  The tatami flooring material 200 laid as shown in FIG. 11 hardly moves unless the tatami flooring material 200 is given a special external force.

  In FIG. 11, the short sides 102c and 102d of each tatami flooring material 200 are laid on the same line in the direction along the y-axis, but the arrangement is the same as in FIG. By laying in this way, it is possible to obtain an alternating mosaic pattern.

  Further, the length of the tatami flooring material 200 in the long side direction is a standard size (600 mm) and, for example, 1/2 size (300 mm), 2/3 size (400 mm), and 3/4 size of the standard size. (450mm), etc., and if the tatami flooring material of these sizes is interposed in the middle of the direction along the long side (direction along the x axis), for example, without cutting the tatami flooring material The laying range in the direction along the long side of the tatami flooring material can be arbitrarily set to some extent. Moreover, by preparing such tatami flooring materials having different sizes, laying in an arrangement as shown in FIG. 7B can be easily realized.

  As described above, according to the tatami flooring material 200 according to the second embodiment, since the anti-slip sheet is provided on the back surface of each tatami flooring material 200, the tatami flooring material 100 according to the first embodiment is obtained. In addition to the effect, even when a plurality of the tatami flooring materials are laid in a predetermined range of a part of the room, an effect that the laying can be laid without providing a frame or the like is obtained. For this reason, by using the tatami flooring material 200 according to the second embodiment, it is not necessary to have a specialized contractor or the like construct it, and the tatami flooring material 200 can be easily laid in a desired space.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, the following modifications are possible.

  (1) In the above embodiments, the dimensions of the tatami flooring materials 100 and 200 are exemplified by the case where the long side is 600 mm, the short side is 150 mm, and the thickness is about 17 mm. However, the present invention is not limited to this. . However, when making ordinary tatami mats (width: about 900 mm), considering that the non-conforming rush can be used effectively, the length of the long side (in the direction along the height of the rush) The length is preferably suppressed to 800 mm or less. Moreover, since there exists a subject that it is hard to lay when the length of a long side is too short, as a tatami flooring material, it is preferable to make the length of a long side into the range of 800 mm-200 mm.

  The long side and the short side can be variously set in the range of 800 mm to 200 mm. In each of the above embodiments, the dimensions of the tatami flooring materials 100 and 200 are 600 mm for the long side and 150 mm for the short side. However, the size can be adapted to the size between Kyoto, Chukyo, Edo, and housing estate. Therefore, the long side is “600 mm”, the short side is “150 mm”, the long side is “about 600 mm”, and the short side is “about 150 mm”. It is also possible to have a range. Here, “about 600 mm” is in the range of “550 mm to 650 mm”, and “about 150 mm” is in the range of “140 mm to 160 mm”.

  Moreover, it is preferable that the thickness of the tatami flooring materials 100 and 200 is sufficiently thinner than a normal tatami mat, and it is preferable to be in a range of about 30 mm to 10 mm.

  (2) In each of the embodiments described above, the tatami flooring materials 100 and 200 are strip-shaped (elongated rectangular shapes), but may be square. When the tatami flooring materials 100 and 200 are square, for example, it is preferable that one side has a size of about 300 mm or 450 mm in terms of easiness of laying and appearance. Thus, the 450 mm and 300 mm sizes, like the 600 mm and 150 mm, are 1 / n (where n is a natural number) that is the standard size of a house in Japan. It becomes convenient in various aspects such as ease.

  In this case as well, in order to be able to correspond to the Kyoto size, the Chukyo size, the Edo size, the housing estate size, etc., it is not determined as “450 mm” or “300 mm”, but “about 450 mm” or “ It is also possible to give an allowable range for 450 mm and 300 mm, such as “about 300 mm”. Here, “about 450 mm” is in the range of 420 mm to 480 mm, and “about 300 mm” is in the range of 280 mm to 320 mm.

  (3) In each of the above embodiments, the chamfered portion 113 of the core material 110 is formed by obliquely cutting both end portions 112a and 112b of the core material 110, but the present invention is not limited to this. .

  FIG. 12 is a view for explaining a modified example of the chamfered portion 113 formed in the core member 110. As shown in FIG. 12, the chamfered portion 113 formed in the core material 110 may be one in which each corner of the four corners of the core material 110 is cut into an L shape. In this case, the length L10 in the direction along the long side of the part to be cut is about 30 mm to 40 mm, and the length L11 in the direction along the short side is about the thickness of two tatami mats (for example, 3 mm to 4 mm). Is preferred.

  (4) In each of the above embodiments, the pedestal 130 is attached to the lower surface of the core material 110 to form a pedestal on the lower surface side of the core material 110. However, the pedestal is integrally molded with the core material. It may be a thing. Thus, by making the base integrally formed with the core material, it is not necessary to prepare the accessory plate 130 as a separate part.

  (5) In each said embodiment, although the core material 110 used what shape | molded by compressing what was pulverized and pulverized the wood, it was not restricted to this but was made with plywood. It may be a thing.

  Further, the core material is not necessarily manufactured using wood as a raw material, and may be manufactured using a synthetic resin, for example. Further, a synthetic resin may be molded on at least the upper surface of a wooden core material (for example, the core material 110 used in the embodiment). If the synthetic resin has an appropriate elasticity, the cushion material 120 may not be interposed between the tatami surface 140 and the core material 110 in some cases. In addition, by using synthetic resin for the entire core material 110, a base equivalent to the accessory plate 130 can be easily formed by integral molding.

  (6) In the second embodiment, the anti-slip sheet 220 has a similar shape to the tatami flooring material main body 210 (tatami flooring material 100), and the length of the side in the horizontal direction and the side in the vertical direction of the anti-slip sheet 220. The length of the tatami flooring material body 210 (tatami flooring material 100) is the same as that of the tatami flooring material main body 210 (tatami flooring material 100). One or both of the lengths may be smaller than the tatami flooring material body 210 (tatami flooring material 100). Further, if the anti-slip effect can be obtained and the adjacent tatami flooring materials can prevent the non-slip sheets from overlapping each other, the tatami flooring material body 210 (tatami flooring material 100) is necessarily similar. There is no.
