Description

  The present invention relates to a borderless tatami mat and a method of manufacturing a borderless tatami mat, in which a tatami table of natural cocoon grass is arranged on the upper surface of a tatami mat floor, and a peripheral portion of the tatami mat table is folded into an outer peripheral side surface of the tatami mat floor.

  As a typical rimless tatami mat, for example, a natural tatami mat tatami table is placed on the upper surface of a square or rectangular tatami mat floor, and the periphery of the tatami mat is folded into the outer peripheral side of the tatami mat floor to fold the tatami mat. The thing fixed with respect to the tatami floor is known (for example, refer patent document 1). However, as an edgeless tatami mat, for example, a tatami mat floor whose top surface shape is designed to be a polygon having a corner other than 90 degrees has been proposed. When the edgeless tatami mat is designed to be a polygon having a corner other than 90 degrees in this way, there are places where the folding floor must be cut obliquely with respect to the seam. When the tatami floor is cut diagonally with respect to the seam, the thread that compresses and sews the heel is broken and easily unraveled, and the tatami floor is greatly expanded by the resilience of the heel and the tatami is formed cleanly. There was a problem that was difficult. Moreover, also about a tatami mat, the tatami mat will be cut | disconnected diagonally with respect to eyes, and the location which must be bent diagonally with respect to eyes will come out. There is a problem that it is difficult to bend the tatami surface obliquely with respect to the eyes, and the strength of the folded portion is reduced. Further, when the tatami mat is cut obliquely with respect to the eyes, there is a problem that the tatami mat is likely to be unraveled.

  The present invention has been made based on such a problem, and an object thereof is to provide a borderless tatami mat and a borderless tatami mat manufacturing method that can be manufactured cleanly and easily.

  The edgeless tatami mat of the present invention is such that a natural tatami mat tatami table is placed on the upper surface of the tatami mat floor, and the periphery of the tatami mat table is folded on the outer peripheral side surface of the tatami mat floor, and the upper surface shape of the tatami mat floor is at least It is a polygon having a single acute angle, and a foldable floor corner reinforcing member made of non-woven fabric is attached to the outer peripheral side surface of the sharp angled corner of the tatami mat floor. It has a crease that folds along the outer peripheral side surface, and a crease reinforcing member made of a nonwoven fabric is attached to the back surface of the peripheral portion of the tatami mat on a portion corresponding to the crease provided obliquely with respect to the tatami mat face. .

  The edgeless tatami mat manufacturing method of the present invention is to manufacture a rimless tatami mat by placing a natural tatami mat tatami table on the upper surface of the tatami mat floor and folding the peripheral edge of the tatami mat table to the outer peripheral side surface of the tatami mat floor, After the folding floor material is cut and the upper surface is cut into a polygonal folding floor having at least one acute angle, and the folding floor cutting process, the outer peripheral side surface of the acute angle corner of the folding floor Tatami mat floor corner reinforcement process to apply the adhesive and paste the tatami mat floor corner reinforcement member made of non-woven fabric, and tatami mat table cutting process to cut the tatami mat material according to the shape of the mat floor and cut out the tatami mat table After the tatami table cutting process, after the tatami table cutting process, a crease forming process for forming a crease that folds the peripheral edge along the outer peripheral side surface of the tatami mat floor; Folds made of non-woven fabric at the part corresponding to the folds that are oblique And fold the reinforcing step of pasting member, is intended to include a fixing step of fixing the tatami mat straw tatami floor.

  According to the edgeless tatami mat and the edgeless tatami mat manufacturing method of the present invention, the tatami mat floor corner reinforcing member made of non-woven fabric is attached to the outer peripheral side surface of the acute angle corner of the tatami mat floor. It is possible to reinforce the corners of the glass and prevent the shape of the corners from breaking and deforming. In addition, since the crease reinforcing member made of nonwoven fabric is attached to the portion corresponding to the fold provided obliquely with respect to the eyes of the tatami surface on the back surface of the peripheral portion of the tatami surface, the periphery provided obliquely with respect to the eyes In addition to reinforcing the portion, it is possible to prevent the peripheral portion from being unwound.

  Furthermore, if a tatami surface corner reinforcing member made of non-woven fabric is attached to the acute angle corner portion of the surface of the rim surface of the tatami surface, the corner portion of the rim surface of the tatami surface is further reinforced and the unraveling is further suppressed. be able to.

  In addition, if an adhesive is applied to the stitch holes located at the peripheral edge of the mat floor, deformation due to expansion of the mat floor can be suppressed. In addition, if an adhesive is applied to the end portion of the tatami mat that is cut obliquely with respect to the eyes, it is possible to suppress the unraveling of the end portion that is cut obliquely with respect to the eyes.

  Furthermore, if the folds are formed after spraying high-temperature and high-pressure steam at a position where the folds are formed obliquely with respect to the eyes of the tatami surface, the folds can be formed cleanly and easily.

  In addition, an original slab with a size obtained by subtracting the thickness of the tatami mat from the dimensions of the edgeless tatami mat to be manufactured is used.

It is a figure for demonstrating the folding floor cutting process which cuts a folding floor material. It is a figure which shows an example of another shape.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a configuration of an edgeless tatami mat 1 according to an embodiment of the present invention. FIG. 2 shows an extracted configuration of the folding floor 10 of the edgeless tatami mat 1. FIG. 3 shows a part of the folding floor 10 in an enlarged manner. FIG. 4 shows the structure of the tatami mat 20 of the edgeless tatami mat 1 taken out and developed, with (A) representing the front surface and (B) representing the back surface. For example, the edgeless tatami mat 10 is obtained by arranging a natural tatami mat tatami table 20 on the upper surface of the tatami mat floor 10 and folding the peripheral edge 21 of the tatami mat table 20 into the outer peripheral side surface 11 of the tatami mat floor 10.

  The tatami mat floor 10 is obtained by, for example, compressing a cocoon layer having a thickness of about 40 cm to 50 cm into a thick plate with a machine and cutting the tatami mat floor material sewn with a thread 12 into an arbitrary shape. . The folding floor 10 is cut into a polygon whose top surface shape has at least one acute angle. FIG. 1 shows an example of cutting into a base-type pentagon. In the acute corner portion 13 of the folding floor 10, for example, a folding floor corner portion reinforcing member 14 made of a nonwoven fabric is attached to the outer peripheral side surface 11 with an adhesive. This is because the acute angle portion 13 is easily deformed due to the yarn 12 being unwound and the wrinkles bulging. The folding floor corner reinforcing member 14 is preferably attached so as to cover the outer peripheral side surface 11 from the upper end to the lower end of the folding floor 10, for example. This is because a higher effect can be obtained. The folding floor corner reinforcing member 14 may be attached not only to the acute corner portion 13 but also to the obtuse corner portion 15.

  Moreover, it is preferable that adhesives, such as an instantaneous adhesive agent, are apply | coated to the tatami mat floor 10 at the stitch hole 16 located in a peripheral part. The seam hole 16 is a seam hole of the thread 12 for sewing the heel, and is for suppressing the thread 12 from being unwound by cutting. It is more preferable that an adhesive such as an instantaneous adhesive is also applied to the end of the peripheral edge of the folding floor 10. This is to prevent the shape of the end portion from collapsing.

  Furthermore, the edge reinforcement member which consists of plastic etc. from the upper surface to the outer peripheral side surface 11 and from the lower surface to the outer peripheral side surface 11 so that the edge of the peripheral part of the folding floor 10 may cover the corner | angular of a thickness direction, for example 17 is preferably provided. This is to reinforce the end and improve the finish system. The end reinforcement member 17 is disposed on the folding floor 10 by sewing, for example.

  The tatami mat table 20 is cut into a size larger than that of the tatami mat floor 10 so as to cover the upper surface and the outer peripheral side surface 11 of the tatami mat floor 10, for example. In FIG. 1, the base type pentagon is larger than the folding floor 10. The tatami surface 20 is formed with a fold 22 that bends the peripheral edge 21 along the outer peripheral side surface 11 of the folding floor 10. On the back surface of the peripheral edge portion 21 of the tatami surface 20, for example, a fold reinforcing member 23 made of a nonwoven fabric is attached to a portion corresponding to the fold 22A provided obliquely with respect to the eyes of the tatami surface 20 with an adhesive. When the crease 22A is provided obliquely with respect to the eyes of the tatami surface 20, the strength of the peripheral portion 21 is reduced and the end portion that is cut obliquely becomes easy to be released, so that the peripheral portion is reinforced by the crease reinforcing member 23. This is to suppress the unraveling. In FIG. 4B, the crease reinforcing member 23 is shown with a satin finish.

  On the surface of the peripheral edge portion 21 of the tatami surface 20, it is preferable that a tatami surface corner portion reinforcing member 24 made of, for example, a nonwoven fabric is attached to the acute angle corner portion 21A with an adhesive. This is because the acute angle portion 21A can be further reinforced and the unraveling can be further suppressed. In FIG. 4A, the tatami mat corner reinforcing member 24 is shown with a satin finish. The tatami surface corner portion reinforcing member 24 may be attached not only to the acute angle portion 21A but also to the obtuse angle portion 21B. Moreover, it is preferable that the adhesive agent is apply | coated to the edge part cut | judged diagonally with respect to the eyes of the tatami surface 20. FIG. This is because the end portion can be prevented from being unraveled.

  FIG. 5 is a flowchart showing a method of manufacturing the edgeless tatami 1 of the present embodiment. 6 to 8 are diagrams for explaining each process. First, a place where the edgeless tatami is installed is measured, and for example, the dimension of each edgeless tatami is set based on the design diagram shown in FIG. 6 (step S101; measuring step). In the design shown in FIG. 6, eight edgeless tatami mats 2 having a square top surface shape are arranged at the center, a pentagonal rimless 3 having a pentagonal top shape is arranged at the four corners, and the side wall between the four corners. The base type pentagonal edge untatched 1 which concerns on a form is arrange | positioned.

  Next, as shown in FIG. 7, for example, based on the dimensions determined by measuring, an original board 31 having a size obtained by subtracting the thickness of the tatami mat 20 from the dimensions of the edgeless tatami 1 to be manufactured is produced using a wooden board or the like ( Step S102: original size plate making process). The original size plate 31 has the same shape and size as the upper surface shape of the folding floor 10 to be produced.

  Subsequently, for example, it is preferable to mark the folding floor material 32 by cutting the folding floor material 32 based on the cut line 32A marked on the folding floor material 32 using the produced original size plate 31 (step S103). ; Folding floor cutting process). Specifically, for example, it is preferable to place the original size plate 31 on the folding floor material 32 and mark the folding floor material 32 along the circumference of the original size plate 31 with a cutting line 32A. Thereby, the polygonal folding floor 10 whose upper surface shape has at least one acute angle is cut out.

  In this tatami mat floor cutting process (step S103), for example, after marking the cutting line 32A, as shown by fine satin in FIG. It is preferable to apply an adhesive such as an instantaneous adhesive. This is to prevent the yarn 12 from being unwound by cutting. In addition, as shown by rough texture in FIG. 8, it is preferable to apply an adhesive such as an instantaneous adhesive to the edge of the peripheral edge of the folding floor 10. This is to prevent the shape of the end portion from collapsing.

  Next, for example, as shown in FIG. 3, an adhesive is sprayed on the outer peripheral side surface 11 of the acute corner portion 13 of the mat floor 10 to paste the mat floor floor reinforcing member 14 made of nonwoven fabric. (Step S104; step of reinforcing the floor corner of the folding floor). The folding floor corner reinforcing member 14 may be attached to the outer peripheral side surface 11 of the obtuse corner 15 of the folding floor 10. After that, at the end of the peripheral edge of the folding floor 10, for example, end reinforcement made of plastic or the like from the upper surface to the outer peripheral side surface 11 and from the lower surface to the outer peripheral side surface 11 so as to cover the corner in the thickness direction. It is preferable to sew and arrange the member 17 (step S105; folding floor end portion reinforcing step).

  Further, for example, the tatami mat material is cut according to the shape of the tatami mat floor 10, and the tatami mat table 20 is cut out (step S106; tatami mat cutting process). In the tatami mat cutting process, when the tatami mat material is cut obliquely with respect to the eyes, for example, the produced original size plate 31 is used, and the crease reference line of the fold 22A that is inclined with respect to the eyes is marked on the tatami mat material, and based on that. It is preferable to cut the tatami mat material. In that case, it is preferable to apply the adhesive such as an instantaneous adhesive to a cutting position where the tatami mat material is cut obliquely with respect to the eyes, and then cut. This is because it is possible to suppress the dissolution.

  Next, for example, a crease 22 is formed on the tatami surface 20 to fold the peripheral edge 21 along the outer peripheral side surface 11 of the tatami mat floor 10 (step S107; crease forming step). In the crease formation step, when forming the fold 22A obliquely with respect to the eye, it is preferable to form the crease 22A after spraying high-temperature and high-pressure steam from the front and back surfaces at the position where the fold 22A is to be formed. This is because the fold line 22A can be formed cleanly and easily.

  Subsequently, for example, a crease reinforcing member 23 made of a nonwoven fabric is attached to the portion corresponding to the fold 22A provided obliquely with respect to the eyes of the tatami surface 20 from the back surface of the peripheral edge portion 21 of the tatami surface 20 with an adhesive or the like (step) S108; crease reinforcement step). This is because the peripheral edge portion 21 is reinforced and the unraveling is suppressed.

  Moreover, it is preferable to stick the tatami surface corner portion reinforcing member 24 made of a nonwoven fabric to the acute angle portion 21A of the peripheral edge portion 21 of the tatami surface 20 with an adhesive or the like from the surface (step S109; tatami surface angle portion reinforcing step). This is because the acute angle portion 21A is further reinforced and the unraveling is further suppressed. Note that the tatami surface corner portion reinforcing member 24 may be attached to the surface of the obtuse angle portion 21B of the tatami surface 20 as well.

  After that, the tatami table 20 is arranged on the upper surface of the tatami mat floor 10, and the peripheral portion 21 of the tatami mat table 20 is folded at the outer peripheral side surface 11 of the tatami mat floor 10 at the fold line 22, thereby fixing the tatami mat table 20 to the tatami mat floor 10 (step). S110: fixing step). The tatami table 20 is fixed to the folding floor 10 by sewing, for example. Thereby, the edgeless tatami 1 which concerns on this Embodiment is obtained.

  As described above, according to the present embodiment, the folding floor corner reinforcing member 14 made of a nonwoven fabric is attached to the outer peripheral side surface 11 of the acute corner portion 13 of the folding floor 10. The corner portion can be reinforced to prevent the shape of the corner portion from being broken and deformed. Moreover, since the crease reinforcing member 23 made of a nonwoven fabric is attached to a portion corresponding to the crease 22A provided obliquely with respect to the eyes of the tatami surface 20 on the back surface of the peripheral portion 21 of the tatami surface 20, While reinforcing the peripheral part 21 provided diagonally, the peripheral part 21 can be prevented from unraveling.

  Further, if the tatami surface corner portion reinforcing member 24 made of a nonwoven fabric is attached to the acute angle corner portion 21A on the surface of the rim portion 21 of the tatami surface 20, the corner portion of the rim surface 21 of the tatami surface 20 is further reinforced. , It is possible to further suppress the dissolution.

  In addition, if an adhesive is applied to the stitch holes 16 located at the peripheral edge of the mat floor 10, deformation due to expansion of the mat floor 10 can be suppressed. In addition, if an adhesive is applied to the end portion of the tatami mat 20 that is cut obliquely with respect to the eyes, it is possible to suppress the unraveling of the end portion that is cut obliquely with respect to the eyes.

  Furthermore, if the fold 22A is formed by spraying high temperature and high pressure steam at a position where the fold 22A is formed obliquely with respect to the eyes of the tatami surface 20, the fold can be formed cleanly and easily. it can.

  In addition, an original size plate 31 having a size obtained by subtracting the thickness of the tatami surface 20 from the size of the edgeless tatami 1 to be manufactured is manufactured, and a cutting line 32A is marked on the folding floor material 32 using the prepared original size plate 31. At the same time, if the fold reference line of the fold 22A that is inclined with respect to the eyes is marked on the tatami mat surface material, the edgeless tatami mat 1 having an accurate dimension can be easily produced.

  The present invention has been described with reference to the embodiment. However, the present invention is not limited to the above embodiment, and various modifications can be made. For example, in the above-described embodiment, the base-type pentagon is specifically described as the upper surface shape of the folding floor 10, but another polygon having at least one acute angle may be used. FIG. 9 shows another example.

  In the above embodiment, each component and each manufacturing process have been specifically described. However, all the components or all the manufacturing steps may not be included, and other components or other components may be included. You may have a manufacturing process. Further, in the manufacturing process of the tatami mat table 20, the tatami mat cutting process (step S106), the crease forming process (step S107), the crease reinforcing process (step S108), and the tatami mat corner reinforcing process (step S109) have been described in this order. The order of the process (step S107), the crease reinforcement process (step S108), and the tatami mat corner reinforcement process (step S109) may be any first.
