Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of carpets, mats, and other mats, especially mats for bathrooms, restrooms, kitchens, etc., and floor mats for footwear cleaning, which are also called so-called dust control mats.

[0002]

[Prior art]

 Floor mats for cleaning rugs, especially this type of footwear, are widely used as cleaning mats that are placed on the floor surface inside and outside doors to remove dirt and dust from footwear with the tufts of the mat body. After use, dirt and dust adhering to the tufts can be removed by washing and reused.

Conventionally, as a mat of this kind, a mat made of fiber backed with a backing material is attached to a thick rubber plate to form an integral mat, or a frame made of a rubber frame. There is a separate type mat that fits the mat body. In each case, a heavy rubber material is placed on the back side of the mat body to prevent slippage with the floor surface due to weight.

[0004]

[Problems to be solved by the device]

 However, the integrated mat has the drawback that the washing efficiency is poor because the rubber must be washed together with the mat body, and since the rubber has poor washing resistance and weather resistance, cracks and cracks in the rubber plate occur after repeated washing. There was a problem that cracks were likely to occur. It may be because the contraction degree of the rubber and the fiber is different when the washing is repeated, but wavy wrinkles are formed, and when this is placed on the floor, the entire surface does not come into flat surface contact with the floor surface. In addition to being unable to effectively prevent slippage with the floor, there was the problem of being caught by the foot. Moreover, the rubber plate was heavier than expected and difficult to carry, which was not preferable in handling.

In the separate type mat, the mat body and the rubber are separate members, so that it is easy to wash and does not cause waviness, but since it is a fitting type, the thickness of the rubber inevitably affects the door opening and closing. There were problems in terms of use, such as obstacles to people and getting caught during walking, and problems due to poor weather resistance. Also, as the mat body is repeatedly washed, the mat body shrinks as described above, so that the mat body becomes loosely fitted into the rubber frame body as it is used, and the mat body moves from the fixed position when used. There was a problem of causing a gap. In this regard, mats with male and female magic tapes attached to the mat body and rubber frame, respectively, to eliminate misalignment are also provided, but there are still problems in terms of use such as opening and closing doors, and heavy rubber. It is hard to say that it is easy to handle because it uses a frame.

The object of the present invention is that the anti-slip effect is good, the washing efficiency is good, the washing resistance is excellent, the composition is more durable than rubber, and it is always flat without wrinkling during use. The point is to provide floor coverings that can be placed on the floor, are lightweight and are extremely easy to handle, especially footwear cleaning floor mats.

[0007]

[Means for Solving the Problems]

 As a result of diligent study to achieve the above object, this device adopts a structure in which a polyurethane elastomer having excellent washing resistance and weather resistance is integrally arranged on the back surface of the rug body as an anti-slip material. . Here, the washing resistance refers to the durability in terms of water resistance, abrasion resistance, cold resistance, chemical resistance, etc., but specifically, it has low water swelling property, such as breaking strength and breaking elongation. It shows that the mechanical or chemical properties are good. Weather resistance mainly means deterioration by ultraviolet rays. It is important that the anti-slip material has low rigidity and relatively low surface hardness.

The polyurethane elastomer of the present invention may have any thermoplasticity or thermosetting property as long as it satisfies the object of the present invention, and even a small amount of foamed material is not particularly problematic. However, from the viewpoint of washing resistance and anti-slip effect, a polyether polyurethane elastomer having a JISA hardness of 85 or less (more preferably 80 or less) is preferable.

Since the non-slip material is used in place of conventional rubber, it is integrated with the back surface of the mat body in the form of a sheet or film with or without a backing material. As the integration method, in the case of a thermoplastic polyurethane elastomer, a method of calender molding (molding and integration of the anti-slip material is performed simultaneously), or a sheet or film urethane elastomer of a wet type, a dry type or a hot melt type is used. There is a well-known lamination method to integrate them. On the other hand, in the case of thermosetting polyurethane elastomer, a urethane resin stock solution is poured onto a base material set in a predetermined mold to react and cure, and a sheet or film urethane tongue elastomer is prepared in advance by batch system and secondary processing is performed. And a method of adhering to the substrate.

Although a simple laminated film can be used as the non-slip material, a water passage portion may be formed in the film. The water passage portion can be obtained by forming water passage holes in a porous state or forming a mesh shape or a stripe shape. Forming the water passage can ensure good water drainage, sand buffing, stone trapping, and aeration, and also allows water vapor to pass through, which is preferable from the viewpoint of the dehydration effect. In particular, when a soft thermoplastic polyurethane film or sheet is used as a non-slip material, the strength around the water-permeable portion is particularly excellent, so cracks start from the water-permeable portion at the time of washing, like conventional rubber. It does not break.

Although the thickness of the non-slip material varies depending on the specific gravity and the like, it is generally preferably about 50 μ to 3 mm, and particularly preferably 50 to 500 μ when a soft thermoplastic polyurethane elastomer is used. If it is less than 50μ, the strength in washing resistance tends to decrease, and if it exceeds 500μ, no further remarkable effect can be expected, which is not preferable from the economical point of view. In the case of a thermosetting polyurethane, the expansion ratio is not limited as long as the effects of the present invention can be fully exhibited, but experience has shown that it is preferably 5 times or less, the thickness is the weight of the product, and the conformability with the matte fiber after repeated washing. Although it is determined from the viewpoint of durability, it cannot be denied that it will inevitably become thicker than non-foamed products (regardless of whether they are thermoplastic or thermosetting). From the viewpoint of exerting the effects of the present invention, it is essential that the thickness of the foam is 3 mm or less.

In the case of polyurethane, the relationship between the anti-slip property and the hardness is large, and when the JISA hardness is 85 or more, it becomes hard and the elasticity and anti-slip effect are inferior, and the effects intended by the present invention are sufficiently exhibited. Not done.

[0013]

[Action]

 Since this invention is a mat with polyurethane elastomer, which has good washing resistance and excellent durability, integrated on the back side of the mat body, even if it is used as a floor mat for footwear cleaning, it can be used with conventional rubber. It is lighter than a board and does not slip. In addition, since it is soft and has a low bulk, it can be easily washed, has good washing efficiency, and is extremely superior in strength. Also, even if the fiber mat body shrinks due to repeated washing, it follows the mat body well, and does not wavy or wrinkle unlike the conventional rubber plate.

[0014]

【Example】

 FIG. 1 is a perspective view showing an embodiment in which the rug according to the present invention is applied to a floor mat for cleaning footwear. In the figure, 1 is a mat body in which tufts 2 are woven, and 3 is a non-slip material made of polyurethane elastomer formed on the back surface of the mat body 1. The polyurethane elastomer which is the anti-slip material 3 in this embodiment is P27 (polyether pellet (JISA hardness 78) manufactured by Nisshinbo Co., Ltd.) as a thermoplastic polyurethane elastomer, and is integrated into the mat body 1 by calendering. It is a thing.

Therefore, even if the floor-standing mat is installed inside or outside the door, the thickness is extremely thin as compared with the conventional separate type, which may cause an obstacle for opening and closing the door, or cause a foot to be caught during walking. There is no problem. In addition, since the non-slip material 3 is a polyurethane elastomer with low hardness, it is not slippery, and because it is lightweight, it is easy to carry after use, and it is extremely easy to wash after use, which has high washing efficiency and strength. Since it has excellent washing resistance and weather resistance, it does not crack or crack like conventional rubber plates. Even after repeated washing, since the film is thin, it follows the shrinkage of the fibers and does not cause a wavy state. In addition, it is flexible and very light so it does not break even when bent, it is easy to handle, and the workability of bedding is greatly improved.

In the embodiment shown in FIG. 2, a large number of water passage holes are further formed in the anti-slip member 3 in the structure of the above embodiment. Therefore, a good drainage state is secured through the water passage hole 4, moisture is not accumulated, and even if there is a water film on the floor surface, the effect of not slipping is further exerted.

Further, in the embodiment shown in FIG. 3, the slip preventing material 5 in which a large number of water passage grooves 6 are formed in a stripe shape is used, and in the embodiment shown in FIG. The anti-slip material 7 having the water holes 8 is adopted. In both cases, the non-slip members 5 and 7 are made of the thermoplastic polyurethane elastomer as in the above-mentioned embodiment. By forming the water passage grooves 6 and the water passage holes 8 in the non-slip members 5 and 7, good drainage is achieved. It also has a sand blast and stone trapping effect to ensure ventilation.

The present invention is not limited to any of the above embodiments. It can be used not only on floor mats for footwear cleaning, but also on carpets and even mats for bathrooms, restrooms, kitchens, etc.

Incidentally, the floor mat of FIG. 1 was tested for weight characteristics, durability, handling characteristics, and non-slip characteristics (deviation characteristics) in comparison with a conventional separate type and an integrated floor mat. It was
