Description

  The present invention relates to a rectangular joint mat in which concave and convex fitting portions for connecting with adjacent joint mats are formed on four sides.

For example, in a living room of a house, a joint mat is known as a floor mat that can be easily laid on a flooring to prevent floor sound insulation and floor damage (for example, Patent Document 1).
The joint mat is formed by integrally forming concave and convex fitting portions for connecting to adjacent joint mats on each side portion of a square mat body made of a soft foam synthetic resin. On the surface of the mat body, for example, a decorative film layer made of an oriented polypropylene (OPP) film printed with a wood grain pattern is laminated.
At the time of use, a floor mat of a desired size is laid on the flooring by sequentially connecting a plurality of joint mats while fitting the concave and convex fitting portions on the side of the abutting side.

  However, in the conventional joint mat, when the user walks on the mat with socks, especially when the child wearing the socks runs around on the mat, there is a risk of slipping and falling. This is because the decorative film layer, which is the walking surface of the mat, has been conventionally produced from stretched polypropylene having a low frictional resistance.

  Therefore, as a result of diligent research, the inventor laid the above-mentioned anti-slip film layer made of a transparent or translucent synthetic resin having a higher frictional resistance than the decorative film layer on the decorative film layer made of synthetic resin. I found out that the problem was solved, and completed this idea.

  In other words, the present invention has been made in view of such problems, and has a high anti-slip property on the surface of the joint mat, so that a user, particularly a child can wear a sock and run on the mat without slipping. The purpose is to provide a mat.

  The invention according to claim 1 is a rectangular joint mat in which concave and convex fitting portions for connecting to adjacent joint mats are formed on each side portion, and a mat body made of a foamable soft synthetic resin. A decorative film layer made of a synthetic resin and laminated on the surface of the mat body, and an anti-slip film layer made of a transparent or translucent synthetic resin and laminated on the surface of the decorative film layer. It is a joint mat.

The size of the joint mat is arbitrary. For example, the height and width may be 30 cm and the length and width may be 60 cm.
When assembling an assembly type floor mat from a plurality of joint mats, mats of different sizes may be appropriately combined without using only joint mats of the same size.
The material (main raw material) of the mat body is arbitrary as long as it is a soft synthetic resin having foamability. For example, foamed ethylene-vinyl acetate copolymer resin (EVA), foamed polyurethane (PU), foamed polyolefin, and the like can be employed.
The thickness of the mat body is arbitrary. For example, it is 5 to 50 mm, preferably 8 to 50 mm, and more preferably 10 to 30 mm.

The decorative film layer is one whose surface becomes the decorative surface (design surface, design surface) of the joint mat.
An arbitrary pattern (pattern) can be printed on the surface of the decorative film layer. For example, a wood grain pattern, a floral pattern, a marble pattern, a geometric pattern, a character, and the like. In addition, a single color may be printed on the entire surface of the decorative film layer.
As the material for the decorative film layer, for example, biaxially stretched polypropylene (OPP), unstretched polypropylene (CPP), ethylene-vinyl acetate copolymer resin, polyvinyl chloride, or the like can be employed. Of these, biaxially stretched polypropylene is preferable because of good color development. As a printing method, gravure printing or the like can be employed.

The coefficient of friction of the decorative film layer is, for example, less than 0.2. Here, the “friction coefficient” is a static friction coefficient defined by JIS-K7125: 1999. A decorative film layer can adjust a friction coefficient small by addition of a lubricant.
As a method for laminating the decorative film layer on the mat body, for example, heat fusion (lamination), adhesion with an adhesive, or the like can be employed.
The thickness of the decorative film layer is arbitrary. For example, it is 10 to 250 μm, preferably 20 to 150 μm, and more preferably 30 to 100 μm.

The material of the anti-slip film layer is arbitrary as long as it is a transparent or translucent synthetic resin having anti-slip properties. For example, low density polyethylene, vinyl chloride resin, polyurethane and the like can be employed. The anti-slip film layer needs to be transparent or translucent so that the surface (printing surface) of the decorative film layer can be seen through the anti-slip film layer.
The friction coefficient of the anti-slip film layer is arbitrary as long as it is larger than the friction coefficient of the decorative film layer. For example, the friction coefficient is 0.3 or more, preferably 0.4 or more. In order to further increase the friction coefficient of the anti-slip film layer, inorganic particles such as silica or foamable microcapsules may be mixed into the synthetic resin as a raw material.
As a method for laminating the anti-slip film layer to the decorative film layer, for example, heat fusion, adhesion with a predetermined adhesive, or the like can be employed.
The thickness of the anti-slip film layer is arbitrary. For example, it is 10 to 250 μm, preferably 20 to 150 μm, and more preferably 30 to 100 μm.

  The invention according to claim 2 is the joint mat according to claim 1, wherein the material of the decorative film layer is biaxially stretched polypropylene and the material of the anti-slip film layer is low-density polyethylene.

Biaxially stretched polypropylene (OPP) is a polypropylene stretched in two directions.
The friction coefficient of low density (soft) polyethylene is not limited as long as it is larger than the friction coefficient of biaxially oriented polypropylene. As an example, the friction coefficient of biaxially stretched polypropylene is 0.2, and the friction coefficient of low density polyethylene is 0.5.
The decorative film layer of biaxially stretched polypropylene and the anti-slip film layer of low density polyethylene can be bonded together by, for example, heat sealing.

  According to a third aspect of the present invention, the material of the foamable soft synthetic resin is a foamed ethylene-vinyl acetate copolymer resin, and a wood grain pattern is printed on the surface of the decorative film layer, and the anti-slip film layer of the joint mat The joint mat according to claim 1 or 2, wherein the side is embossed.

As the wood grain pattern, for example, a square pattern or a board pattern can be appropriately employed.
The emboss shape (uneven shape) is arbitrary. For example, a rectangle, a circle, an ellipse, etc. can be adopted.
The (planar) size of the concavo-convex portion appearing by embossing and the depth of embossing are arbitrary.

  According to the first aspect of the present invention, since the anti-slip film layer having a coefficient of friction larger than that of the film layer is laminated on the surface of the decorative film layer of the joint mat, the anti-slip property is imparted to the surface of the joint mat. be able to. Thereby, even if a user, particularly a child, wears socks and walks on the mat or runs, it is difficult to slip and can prevent an injury caused by the user falling.

  In particular, according to the invention described in claim 2, since the material of the decorative film layer is biaxially stretched polypropylene and the material of the anti-slip film layer is polyethylene, high anti-slip property is imparted to the surface of the joint mat at a low cost. Can do.

Further, according to the invention described in claim 3, since the foamed ethylene-vinyl acetate copolymer resin is adopted as the material of the foamable soft synthetic resin, the mat body is lighter than the rubber material, and is elastic and flexible. Excellent in durability, durability, heat retention, soundproofing, water repellency and weather resistance. As a result, the shock at the time of the fall is eased, it is hard to get scratched, the noise to the lower floor is absorbed and sound leakage is prevented, the floor is not cooled in winter, it is hard to deteriorate even when exposed to ultraviolet rays, and chlorine Dioxins are not generated even if incinerated because they are not included.
Moreover, since the wood grain pattern was printed on the surface of the decorative film layer, the same warmth as that of the wooden flooring can be given.
Further, since the embossing is performed on the anti-slip film layer side of the joint mat, the anti-slip property on the surface of the joint mat can be further enhanced.

It is a perspective view of the joint mat concerning Example 1 of this device. It is a principal part expanded sectional view of the joint mat which concerns on Example 1 of this invention.

  Hereinafter, embodiments of the present invention will be specifically described. Here, a joint mat, which is a part of an assembly-type floor mat laid on a flooring in a living room, is taken as an example.

  1 and 2, reference numeral 10 denotes a joint mat according to the first embodiment of the present invention. The joint mat 10 has concave and convex fitting portions 11 for connecting to adjacent joint mats 10 on each side portion. 12 (concave fitting portion 11 and convex fitting portion 12) is formed in a square shape, and is formed of a mat body 13 made of a foamable soft synthetic resin and laminated on the surface of the mat body 13 and made of a synthetic resin. A decorative film layer 14 and an anti-slip film layer 15 laminated on the surface of the decorative film layer 14 and made of a translucent synthetic resin are provided.

Hereinafter, these components will be specifically described.
The main raw material of the mat body 13 is foamed ethylene-vinyl acetate copolymer resin (EVA), and its size is 30 cm on a side and 10 mm (or 20 mm) in thickness. On the four sides, a large number of concave fitting portions 11 and convex fitting portions 12 are alternately arranged at a predetermined pitch. The mat body 13 may be subjected to antibacterial treatment.
The main raw material of the decorative film layer 14 is biaxially stretched polypropylene that has high strength and is difficult to stretch. As a result, the decorative film layer 14 has a friction coefficient of 0.2, and is relatively slippery. The coefficient of friction here is a coefficient of static friction defined by JIS-K7125: 1999 (hereinafter the same).
The decorative film layer 14 has a thickness of 50 μm, and the surface thereof has a full-color gravure print on the surface.
The main material of the anti-slip film layer 15 is low-density polyethylene, and its friction coefficient is 0.5, which makes it difficult to slip.
The thickness of the anti-slip film layer 15 is 50 μm.

  At the time of manufacturing the joint mat 10, a decorative film layer mainly composed of biaxially oriented polypropylene (melting point around 165 ° C.) on the surface of a thick sheet of foamed ethylene-vinyl acetate copolymer resin (melting point 70 ° to 110 ° C.). 14 and low-density polyethylene (melting point: 100 ° C. to 115 ° C.) are superposed on the anti-slip film layer 15 as a main raw material, and thereafter, the surface side is thermocompression-bonded by one pressure roller. The heating temperature at this time is 180 ° C. to 200 ° C. in consideration of the decorative film layer 14 having the highest melting point. Next, the obtained thick layered sheet with a three-layer structure is die-cut with a die having a predetermined shape. Thereby, the joint mat 10 is manufactured.

Further, the joint mat 10 is embossed with circular concavo-convex portions having a diameter of several millimeters and a depth of several millimeters on the anti-slip film layer 25 side (surface side) at a pitch of several millimeters in length and breadth. This processing is performed by pressing a hot embossing roll in which embossing protrusions are arranged on the outer peripheral surface at a pitch of several millimeters in length and width against the surface side of the three-layer thick ground sheet before being punched. In addition, this joint mat 10 is good also as floor heating and a non-formaldehyde specification.
The joint mats 10 thus obtained are sequentially connected while fitting the concave fitting portions 11 and the convex fitting portions 12 on the side of the abutting side on the living flooring. As a result, an assembly type floor mat having a desired size is laid on the flooring.

Thus, since the anti-slip film layer 15 having a friction coefficient larger than that of the decorative film layer 14 is laminated on the surface of the decorative film layer 14 of the joint mat 10, high anti-slip properties are imparted to the surface (walking surface) of the joint mat 10. Can do. Thereby, even if a user, particularly a child, wears socks and walks on the mat or runs, it is difficult to slip and can prevent an injury caused by the user falling.
Moreover, since the main raw material of the decorative film layer 14 is biaxially stretched polypropylene and the main raw material of the anti-slip film layer 15 is low-density polyethylene, high anti-slip properties can be imparted to the surface of the joint mat 10 at a low cost.

Furthermore, since the foamed ethylene-vinyl acetate copolymer resin is adopted as the main raw material of the mat body 13, the mat body 13 is lighter than the rubber material, and has elasticity, flexibility, durability, heat retention, sound insulation, Excellent water repellency and weather resistance. As a result, the impact when the user falls is mitigated, the mat is hard to be damaged, and the noise to the lower floor can be absorbed to prevent sound leakage. In addition, it eliminates cold flooring in winter and is not easily deteriorated even when exposed to ultraviolet rays. Since it does not contain chlorine, it does not generate dioxins even when incinerated.
Moreover, since the wood grain pattern was printed on the surface of the decorative film layer 14, the warmth equivalent to a flooring can be provided to the floor on which the joint mat 10 is laid.
Further, since the embossing is performed on the anti-slip film layer 15 side of the joint mat 10, the walking surface of the joint mat 10 becomes more difficult to slip.

  This device is useful as a technique for improving the slip resistance of a joint mat laid on a flooring in a living room of a house.
