Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wide rug made of artificial rush which is excellent in aesthetics and fashionability in addition to being easy to lay on site, which is easy to adjust dimensions in a room.

[0002]

2. Description of the Related Art Conventionally, the dimensions of a room in which tatami mats are laid are affected by the dimensional accuracy of the building itself, and even if the rooms are the same 6 tatami rooms, each room has a slightly different size. Each room was measured individually, and the tatami mats that fit the room were subtly changed in size and laid. In addition, with the recent changes in the housing structure and the aging of the house, the need for a barrier-free structure has been desired, and the demand for thinner tatami mats has become stronger. Therefore, it is possible to process a thinner than the normal thickness (55 mm), which is a so-called thin tatami mat. However, the measurement of tatami mats is still done by the tatami craftsmen in a room-by-room time period.

[0003] In addition, at present, rugs are laid with a size smaller than the size of the room, or a large size is bent or cut in accordance with the size of the room. In particular, a large-sized product which was bent or cut was not good-looking because a step was formed and a fray was formed at the time of cutting.

[0004]

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks of the prior art, the present invention provides an artificial grass which is easy to lay on site and can be easily adjusted to the size of a room, and which is excellent in aesthetics and fashion. It is intended to provide wide rugs.

[0005]

The present invention employs the following means to solve the above-mentioned problems. That is,
The artificial rush broad rug of the present invention is a wide rug in which a plurality of rug units made of thermoplastic resin artificial rush are connected, and at least a peripheral portion of the wide rug is bordered with an adhesive tape. It is characterized by having been done.

[0006]

DETAILED DESCRIPTION OF THE INVENTION The present invention addresses this problem, namely,
A wide rug made of artificial rush, which is easy to lay on site that can be easily adjusted to the room size and has excellent aesthetics and fashionability, has been studied diligently. In other words, they have sought to achieve mutually opposing functions at once by edging with a polyolefin-based fiber adhesive tape, which is also colored with a colored tape having the same hue.

That is, when laying a tatami mat, the most important thing is whether or not a plurality of tatami mats can be laid in accordance with the room size, that is, whether or not the tatami mat can be easily adjusted. At that time, the problem is the final dimension adjustment, and the present invention emphasizes this point. That is, at least the peripheral portion of the wide rug is trimmed with a specific tape, so that the portion cut for size adjustment can be formed without impairing any aesthetic appearance and further adding excellent aesthetics and fashionability. The laying was completed. Such an effect can be achieved by employing such a rimming technique in joining the interior rug units to achieve laying construction with excellent aesthetics and fashionability.

The artificial rush of the present invention includes, for example, polypropylene, polyethylene, copolymers of propylene and ethylene and mixtures thereof, polyamide resins, polyester resins, acrylic resins, mixtures thereof and copolymers. It is composed of a resin composition mainly composed of a thermoplastic resin such as a united resin.

A tatami mat is made by weaving using such artificial rush as a weft. In some cases, the tatami mat can be made by changing the pitch of the warp or by jacquard weaving like a flower mat.

[0010] After the tatami mat is cut into an appropriate size, a tatami mat floor and a cushion material layer are provided on the back surface of the tatami mat to produce the artificial rush rug unit of the present invention. When the tatami mat is used as it is and a tatami floor or a cushion material layer is provided on the back surface, the unit is cut into an appropriate size and then made.

When the artificial rush grass rug unit is provided with the cushion material layer, when it is laid on a flooring, it has good adhesion to the floor surface, and is particularly effective for preventing displacement. The cushion material layer (made of a thermoplastic resin) is composed of a layer made of at least one selected from an elastic resin sheet layer, a foamed resin sheet layer, and a nonwoven fabric sheet layer.

The tatami floor is constructed by using a hard resin sheet of a thermoplastic resin, for example, a polystyrene resin among foamed resin sheets made of a thermoplastic resin as the cushion material, and laminating a nonwoven fabric sheet on the surface thereof. Those are preferably used. Of course, in order to express the natural sensation, the surface may be made of straw instead of non-woven fabric.

As the cushioning material layer, a sheet-like material made of a thermoplastic resin, in particular, an elastic resin, a foam resin and a nonwoven fabric can be used. As such thermoplastic resins, for example, elastic resins and foam resins are polyethylene, polypropylene, copolymers of propylene and ethylene and mixtures thereof, polyamide, polyester, polyacrylonitrile, copolymers and mixtures of these, polyurethane, Polystyrene, polyvinyl chloride, mixtures thereof and the like can be used.

Among these, the foamed resin sheet can be made of a material selected from a sheet and a linear body. As the foam resin linear material, a material having a cushion layer arranged in at least one direction, preferably a sheet arranged in a lattice or net shape is used. Further, as the foamed resin linear body, a thick and thin continuous linear body may be used.
Alternatively, a continuous linear body having a bead shape can be used. As another example, a sheet-like material in which a foamed resin is covered around each woven yarn or mesh yarn of the open base fabric can be preferably used. It is preferable that the gap A between the open base cloths has an interval of at least 0.5 mm or more. A sheet obtained by dipping the open base cloth into a liquid thermoplastic resin kneaded with a foaming agent and then foaming by heat treatment or the like to form a foam resin sheet can be used. By using such a foamed resin sheet, it is possible to structurally increase the anchoring effect between the floor surface and the adhesive when bonding to the floor surface. In addition, as a material that can be applied to the opening base fabric, a thermoplastic resin fiber, a natural fiber, or the like described below can be appropriately used. It is important that this base fabric has an open structure,
It does not matter what processing method such as weaving, knitting, injection molding and the like. By setting the expansion ratio of the foam resin to at least 1.5 times or more, irregularities on the floor surface will not be picked up, and the rug will have excellent smoothness when laying and will not slip. Furthermore, by the open structure of the foamed resin sheet,
It will greatly contribute to weight reduction.

Next, as long as the non-woven fabric is entangled with fibers, various types of non-woven fabrics such as short fibers, melt blown, spun bond, etc., for example, those made of fiber waste can be applied. The soft, low specific gravity of the non-woven fabric and the low anisotropy of the sheet make it a comfortable carpet that does not damage the flooring surface and provides a moderate cushioning when walking on a rug. This is a very important point.

The basis weight of the nonwoven fabric is preferably 1000
g / m ² or less, more preferably 300 to 800 g / m
^When those in the range of ² are made into carpets, they are lightweight and excellent in handling such as laying work.

As a material constituting such a nonwoven fabric, a mixture with a natural fiber can be used in addition to the above-mentioned thermoplastic resin material. Such natural fibers include, for example,
Wool, cotton, hemp, rayon, pulp, fiber waste thereof, and mixtures thereof can be used. of course,
The effect of the present invention can be achieved even in combination with such a cushion material composed of only natural fibers.

In the case of a carpet-like material, the thickness of the cushion material layer is required to be at least 0.5 mm or more in view of adhesion to the floor and adhesion to the tatami mat. Considering the door contact at the time, the total thickness of the tatami carpet is preferably 15 m
m or less, more preferably 8 mm or less. But,
This thickness slightly varies depending on the gap between the floor to be laid and the door, but can be freely set by adjusting the thickness of the cushion layer. In the case of a tatami feeling, a thickness similar to that of a normal tatami mat is inevitably required, that is, a tatami mat having a thickness of about 5 cm is used.

In order to laminate such a cushion layer and the tatami mat, an appropriate method such as sewing, fusing or adhesive is used. For example, as the adhesive, a rubber-based, epoxy-based, urethane-based, or silicon-based adhesive can be appropriately selected according to its material. Further, it is also possible to perform heat fusion using a low melting point polymer powder or the like, or directly heat fusion by heating the tatami surface and the nonwoven fabric surface.

The wide rug of the present invention is constituted by connecting a plurality of rug units made of thermoplastic resin artificial rush, particularly preferably a polyolefin resin artificial rush, and preferably comprises The rug unit is bordered by an adhesive tape having the same system hue, that is, the unit rug and other adjacent unit rugs,
At least the edge of the upper surface is covered and joined with the adhesive tape. For example, the periphery of each of the unit rugs may be bordered by the adhesive tape, and the adhesive tape may be further covered and joined by another adhesive tape.

The adhesive (including the pressure-sensitive adhesive) constituting the adhesive tape varies depending on the material of the adherend.
For example, vinyl acetate / acrylic resin, SBS / SIS
Resin, vinyl acetate resin, nitrocellulose resin,
At least one selected from a polyurethane resin, a cyanoacrylate resin, a silicon RTV resin, a synthetic rubber, glue, and a mixture thereof can be preferably used.

As the tape, a base cloth or a film constituting an adhesive tape can be usually used, but a cloth base material is preferably used from the viewpoint of aesthetics and fashionability. . Among such cloth-like materials, it is preferable that the artificial rush is made of a fiber made of a polymer of the same type as the resin constituting the artificial rush. For example, in the case of a polyolefin-based artificial rush, an adhesive made of a polyolefin-based fiber fabric is used. When a tape is used, the shrinkage behavior of both tapes matches during the season, so that wrinkles are less likely to occur, and furthermore, the tape has advantages such as easy handling due to its heat-fusing property and is preferably used. That is, the use of the adhesive tape made of the base fabric made of the polyolefin fiber has an advantage that the edge can be trimmed by the heat-sealing means without using the adhesive. That is, the adhesive tape according to the present invention includes one using a heat-sealing type resin as a bonding agent. The heat-fusible resin in this case is preferably a polyolefin resin, a copolyester, a copolyamide, or the like.
A 20.degree. C. low melting polymer can be used.

The width of the adhesive tape is not particularly limited, but is preferably used according to the border of a normal tatami mat. For example, a tape having a width of 1 to 10 cm and a thickness of 2 mm or less is preferable for workability and adhesiveness. It is preferably used from the viewpoint of surface, and from the viewpoint of occurrence of unevenness when it is attached to the lower surface of a tatami carpet.

In the present invention, after the peripheral portion of the artificial rush broad rug is edged with such an adhesive tape, it may be further joined by sewing means.

The artificial rug wide rug of the present invention has a configuration as shown in FIG. 1 which borders the periphery of a wide tatami carpet-like rug. As shown in FIG. The edge of the unit may be bonded and joined by using the adhesive tape so as to sandwich the upper and lower surfaces thereof.
In such an artificial rush wide rug, at least the peripheral portion of the wide rug may be bordered with a polyolefin fiber adhesive tape having the same hue, for example, the tatami carpet unit constituting the inside is In the abutted state, the unit edges may be bonded and joined together on the lower surface. In short, when the entire room is laid as one wide tatami carpet-like rug, the overall balanced aesthetics There is no limitation on the color and pattern of the adhesive tape as long as it has fashionability.
