Description

Tiling for tatami

Technical field

 The present invention relates to a tiled tatami mat that can provide the taste of tatami mats.

I do.

Background art

 Tatami is a traditional flooring of Japanese houses, but due to the recent westernization, the number of occupied tatami floors in houses has increased, and tatami mats have been placed on a part of the floor between these occupants. Various uses have been proposed, such as laying it down and using it instead of power.

 Under such circumstances, tatami mats use synthetic resin products such as polypropylene instead of rush as a material for the tatami mat (see Japanese Patent Application Laid-Open No. Hei 9-62026). Tatami mats mainly made of foam such as foamed polystyrene instead of straw (Japanese Patent Application Laid-Open Nos. 7-189463 and 8-151774) See) has begun to appear. Traditionally, tatami mats are sewn with fringes extending along both side edges, but industrialized tatami mats without such fringes have also been proposed (Japanese Patent Application Laid-Open No. Hei 7-189463). Gazette): In this industrialized tatami, the traditional tatami mat was separated from the tatami mat as a separate part, and after the tatami mat was laid, the tatami mat material was installed and taught. I have.

 By the way, the following is a description of the traditional method of making a tatami mat with a marginal band, according to the process.

 (1) Place the tatami mat on the tatami floor;

(2) Connect both ends of the tatami mat to the back of the longitudinal end of the tatami floor, Fold in;

 (3) Cutting both sides of the tatami mat, ie, the side edges, along the side of the tatami mat, ie, along the side of the tatami mat;

 (4) Place the inverted rims on both sides of the tatami mat, and sew the rims on the tatami floor through the tatami mat;

 (5) Fold the marginal band along the seam, sew along the side of the base material, and then sew it on the side of this tatami floor.

Also, the method of making industrialized tatami mats is basically the same as traditional tatami mats, except for the step of sewing the medals mentioned above ₌

 (1) Place the tatami mat on the tatami floor;

 (2) Fold both ends of the tatami mat to the back side of the longitudinal end of the tatami floor, that is, to the back side of the frame;

 (3) Fold both sides of the tatami mat so as to cover the sides of the tatami mat floor, and sew it to the side of the tatami mat floor.

 However, as mentioned earlier, the current situation is that demand for tatami mats continues to decrease year by year due to the recent trend of westernization. Disclosure of the invention

 In the search for a new use of tatami mats that breaks the above-mentioned situation, the inventor of the present application departed from the concept of existing tatami mats, and if tatami mats could be used like tiling members, The present invention was devised with the recognition that a new market could be created.

 Therefore, an object of the present invention is to provide a tiling tatami that is convenient for tiling.

A further object of the present invention is to provide a tiled tatami mat with cushioning properties. It is a further object of the present invention to provide a tiling tatami that, when stepped on, gives the same feeling as a tatami made of a natural material.

 Another object of the present invention is to provide a tying tatami mat that can prevent the edges of the tatami mat from being unraveled or fuzzy during use. It is in.

 According to the present invention, there is provided a base material; a tatami mat having the same size as the base material and adhered to an upper surface of the base material; an edge of the tatami mat adhered to the base material. This is achieved by providing a tiled tatami mat having means for preventing fluffing of the part.

 As means for preventing fluffing, the edge of the tatami mat may be chamfered and then the chamfered portion may be covered with a protective film, or the edge of the tatami mat and the base may be used. It may be composed of an adhesive tape covering the side surface of the material. As means for preventing fluffing, the edge of the tatami mat may be flattened by applying a heat press treatment, and the flattened portion may be covered with a protective film. As a means to prevent this, the edge of the tatami mat may be formed with an overcast. In this case, the overcast portion is flattened by applying heat press treatment. It may be. Preferably, the overcast portion is covered with a protective film. BRIEF DESCRIPTION OF THE FIGURES

First Embodiment (FIGS. 1 to 4)

 In FIG. 1, reference numeral 1 designates a tatami mat of the first embodiment according to the present invention. This tiled tatami 1 is composed of a base material 2 that can be cut and a tatami table 3 provided on the base material 2. For example, if the use is for flooring, a tatami mat for a Japanese-style room is used. The dimensions are as small as possible, for example, a square having a side of, for example, 300 to 750 mm when viewed in a plan view, and preferably a square having a side of about 500 mm. The thickness of the tatami mat 1 is 5 to 20 mm, preferably 5 to 18 mm, and particularly preferably 6 to 12 mm.

Tatami Table 3 is made of natural or synthetic resin rush or wood-based fiber. In the case of natural rush, a plurality of tatami mats may be joined by using the "medium pulp" technology. Explaining this "middle tie" technology, Only the best part of long rush is used, and two rushes are used in the width direction of the tatami mat. In the industry, this tying technique is called “medium tying”.

 In addition, the current state of trade of natural rush is described as follows. Only long rush is traded, and rush shorter than a predetermined length is discarded. In other words, the tatami mat of a common tatami mat is made of a single real rush, and the portion to be used is a portion sandwiched between the tip of one rush and the root. In other words, since rush is used by cutting its head and root, the trade of rush is limited to rush having a length of 1 m or more. Therefore, shorter rushes were discarded because they were unusable. By the way, the width of single and half tatami mats is about 88 mm or 9555 mm.

 When making Tatami Table 3 with natural rush, for example, if the length of one side of the tiled tatami 1 is set at 50 Om m, relatively short rushes that have been discarded can be used. In addition, if the tatami mat 3 is made by connecting natural rushes in the middle, it is possible to use considerably shorter rushes that have not been watched before. Therefore, by reducing the size of the tiled tatami mat 1 to be smaller than the conventional tatami mat width of about 88 mm or 955 mm, the cost of purchasing rush can be significantly reduced. be able to. In the case of natural rush, it is preferable that the tatami mat 3 be heated and pressed in order to stabilize the quality of the tatami mat 3. This not only eliminates wrinkles and uneven weaving in Tatami Table 3, but also allows chlorophyll to leach out of the natural rush due to the effect of the heating press. There is an advantage if color unevenness can be reduced.

The base material 2 may be mainly composed of a relatively hard board, but is mainly composed of a board made of natural or synthetic rubber. However, in addition, felt or the like may be laminated on the upper surface of these boards. FIG. 2 illustrates an example of a specific structure of the base material 2. The base material 2 is composed of a main layer 2a made of natural or synthetic rubber, and calcium carbonate and polyethylene or It has a structure in which an upper layer 2b made of a polyolefin composite foam or a felt is laminated. FIG. 3 illustrates another specific structure of the base material 2. The base material 2 comprises a wooden board between a main layer 2a of natural or synthetic rubber and an upper layer 2b of a composite foam or felt of calcium carbonate and polyethylene. Having an intermediate layer 2c made of

 Thus, the upper layer 2b made of a composite foam or felt of calcium carbonate and polyethylene or polyolefin is interposed between the main layer 2 and the tatami mat table 3 so that the tiles can be tiled. Tatami mat 1 can be given an appropriate cushioning property. In particular, when the composite foam of calcium carbonate and polyethylene or polyolefin is used as the upper layer 2b, when the tiling tatami 1 is stepped on, the same as a typical tatami mat made of a natural material is used. I knew that I could get a feel.

 When the tiling tatami 1 is made relatively thin, about 6 to 12 mm, the base material 2 should be made of a layer made of composite foam or felt of calcium carbonate and polyethylene or polyolefin. The tiled tatami mat 1 can be prevented from warping by applying a rubber layer or a relatively low elasticity, such as a PVC resin, to the bottom of this layer. be able to. Since the composite foam of calcium carbonate and polyrefin does not generate harmful gas when it is burned, it is desirable to select this material as the base material 2 from the viewpoint of environmental issues.

As can be understood from FIG. 4, the base material 2 and the tatami mat 3 are adhered to each other using an adhesive 4. This adhesive 4 is applied to the base material 2 and Z or May be applied to the entire area of the tatami table 2 entirely, or may be applied in a streak pattern at a pitch of about 1 cm, for example, or may be applied to the periphery 5 (see FIG. 1). only the ₃ may be earthenware pots by applying region, and this modification, as well as entirely coated with adhesive 4 to the peripheral edge portion 5, the adhesive a central region streaked for example about 1 cm pitch Agent 4 may be applied. As the adhesive 4 used here, a commercially available adhesive having appropriate durability may be used, but it does not generate harmful substances such as formaldehyde, and has flexibility and adhesive strength. It is preferable to use a hot-melt adhesive because it is strong, and most preferably, it is a heat-resistant hot-melt adhesive.

 After the tatami mat 3 is adhered to the base material 2, the tatami mat 1 should be provided with means for preventing the edges of the tatami mat 3 from fluffing. As a means for this, a transparent or colored adhesive tape may be prepared, and the adhesive tape may be used to cover the side of the base material 2 from the edge of the tatami mat 3 by force. As another example, the edge of the tatami table 3 may be chamfered, and the protective film 7 may be formed by applying an adhesive resin to the chamfered portion 6. An adhesive resin may be applied from the chamfered portion 6 to the side surface of the base material 2 so that the protective film 7 covers the edge of the tatami table 3 and the side surface of the base material 2. The protective material 7 is preferably made of, for example, a natural rubber-based resin which permeates and solidifies the tatami table 3 to a certain extent, and retains appropriate flexibility. By chamfering, the appearance when the tiled tatami mat 1 is laid can be improved. Also, by covering the peripheral surface of the tiling tatami 1 with the protective film 7, it is possible to prevent "fraying", "fuzzing" or "peeling" of the tatami mat 3 as follows:

Although the chamfer 6 has been described as a means for preventing the fluffing of the edges of the tatami mat table 3, it will be described later in addition to or instead of the chamfer 6. Heat flattening (Fig. 6) to flatten the periphery of the tatami mat 3 and form a protective film 7 covering the side surface of the base material 2 only from the flattened portion or from the flattened portion. May be used.

 The tiled tatami mat 1 according to the present invention is a floor which can enjoy the taste of the tatami mat and the arrangement of the eyes of the tatami mat by laying the tiles on the floor in the same manner as conventional tiled flooring, for example. A surface can be formed. The tiled tatami 1 may be laid by simply laying it on the floor without bonding it to the floor, but the tile tatami 1 may be laid. The tatami mat 1 may be glued to the floor. If the tiling tatami 1 is to be adhered to the floor, it is preferable to apply an adhesive in advance to the bottom surface of the tiling tatami 1 to enhance the workability of the laying work. In this case, a release paper covering the adhesive applied to the bottom of the tiled tatami 1 is pasted, and the tiled tatami 1 is adhered to the floor while removing the release paper during the laying work. It is convenient to do so. In this case, the adhesive may be partially applied to the bottom of the tiled tatami mat〗, or the entire bottom of the tiled tatami mat 1 may be coated with the adhesive. You can.

 If some of the tiled tatami mats 1 must be cut during the laying work, the tatami mats 1 may be cut in the following procedure.

 (1) When the tatami table 3 and the base material 2 are completely bonded in a streak form, the tatami 1 is cut, and the cut surface newly exposed by the cutting is obtained by chamfering the cut edge of the tatami table 3, The protective film 7 is formed by applying an appropriate adhesive (for example, an instant adhesive).

(2) When only the periphery of the tatami mat 3 and the base material 2 are bonded: Before cutting the tatami mat 1, touch the tatami mat 3 along the cutting line. Apply an adhesive (preferably an instant adhesive), fix the tatami mat 3 of the relevant portion to the base material 2, and then perform the cutting work. When this cutting is completed, the newly exposed cutting edge of Tatami Table 3 is chamfered, if necessary, and then a suitable adhesive (for example, instant adhesive) is applied to apply a protective film 7 to the cut surface of Tatami 1. Form.

 Since the above work does not require any special skills, it can be provided to the general public as, for example, “Doit y our self” products. In addition, the tiled tatami mat 1 can be used not only as a floor material but also as a wallpaper for a wall or as a tile for covering a part of the wall. It can be installed on the whole or part of the ceiling of the room. Various methods of use such as sticking to the surface of furniture can be considered as surface materials for visually enjoying the eyes of Tatami Table 3. Of course, it is only necessary to determine whether to use natural rush, synthetic rush or wood-based fiber as the tatami table 3 of the tatami mat 1 according to the application. If you decide the thickness and the size of the tatami mat 1
