[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mat for use in a place where a relatively high frequency of walking such as a golf course, a hotel, a restaurant, a shopping center, an airport terminal building, and a doorway of a building.

[0002]

2. Description of the Related Art Mats made of waste tires containing fiber cords such as nylon used in aircraft, buses, trucks and the like have been used in places where frequent walking and entrances and exits of buildings are used. I have. The mat using the waste tire is obtained by processing a fiber cord in a rubber layer of the tire so that the fiber cord is fluffed up to the surface of the mat, and is processed into a mat shape so as to have an appropriate thickness. Mats processed in this way are excellent in durability against walking, abrasion resistance, dust removal effect, and have the characteristics of not slipping even when wet with water, and are widely used mainly in places with a large amount of walking. .

[0003]

Since the above-mentioned mat is made of rubber, it has a large dimensional change due to a temperature change.
Since the surface is a brushed fiber cord, it absorbs moisture from the surface and warps convexly, so when laying this mat, it is adhered to the lower ground such as concrete like nitrile rubber etc. It was necessary to perform the bonding work firmly with a strong adhesive. However, when such an adhesive construction is performed, the base and the mat are firmly fixed,
There was a problem that even if the mat was dirty, it could not be removed and cleaned, or replaced with a new mat. In addition, when mats are bonded and installed, there is a problem that the mats prevent drainage when the mats are laid at entrances and exits of buildings or outdoors. The present invention provides a mat that solves these problems.

[0004]

In order to solve the above problems, the means of the present invention have a large number of fiber cords buried vertically inside the rubber layer, the ends of which are fluffed and project from the upper surface of the rubber layer. A plurality of strip-shaped rubber simple bodies are formed side by side adjacent to each other, and the rubber simple bodies are not bonded and bonded to each other, but a base material is bonded to a back surface to form a rubber mat, and the back surface of the rubber mat has a moderate deflection. That is, a hard support plate is joined, and a soft sheet having a large number of soft projections on the lower surface is joined to the back surface of the support plate.

[0005]

[Function] The laying mat of the present invention can be simply laid without having to be adhered to the base with an adhesive like a conventional rubber mat. The mat adheres well and follows the irregularities on the ground, so that the mat does not float or pop.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a mat according to the present invention will be described with reference to the drawings. The rubber mat A of the present invention is formed into a mat of an arbitrary size by forming a plurality of elongated strip-shaped rubber simple bodies a using waste tires adjacent to each other in parallel and joining a base material b such as a base cloth to the back surface. The rubber simple substance a is an elongated strip using waste tires, and a fiber cord 1 such as nylon (polyamide) is buried in the rubber layer 2 substantially perpendicular to the rubber simple substance a. The end of the fiber cord 1 is made to protrude from the surface of the rubber layer 2 and fluffed.
One or more sheets are arranged, a hard support plate B having the same size as the rubber mat or slightly smaller than the rubber mat is joined to the back surface, and a convex protrusion 3 having the same size as the support plate B is provided on the back layer. The sheet C is joined and laminated.

When arranging a plurality of rubber mats A on the upper surface of the support plate B, the rubber mats a may be arranged in a single row or in a plurality of rows so that the strip-shaped rubber single bodies a have the same direction or alternate directions. is there.

[0008] The support plate B of the present invention is a rigid one having a moderate bending, and is made of a metal plate, a wooden plate such as veneer, or the like.
Although not particularly limited, such as a plastic plate, it is preferable to use a hard plastic plate such as a vinyl chloride resin, a polycarbonate resin, a polyester resin, and an acrylic resin. The thickness of the support plate B is 1 to 5 mm in order to improve the compatibility with the foundation such as concrete to be laid.
The support plate may be a support plate in which a plurality of thin sheet-like plates are stacked, since a plate having a thickness of about 2 mm, preferably about 2 to 3 mm has an appropriate bending. The support plate B is the same size as the rubber mat A or slightly smaller than the rubber mat, and preferably smaller by about 4 to 10 mm.

The soft sheet C, which forms the lowermost layer, improves the adhesion to the base on which the mat is laid, prevents rattling, and improves the frictional force with the base such as concrete, so that the mat deviates from the base. The sheet is further provided for draining mud or rainwater that has fallen around the mat or around the mat, and the material of such a sheet is not particularly limited as long as it is a soft material such as plastic or rubber. For example, polyvinyl chloride resin, polyethylene, polypropylene, olefin resin such as ethylene-vinyl acetate copolymer resin, synthetic resin such as polyester resin, urethane resin, nitrile rubber, chloroprene rubber, ethylene-propylene rubber, styrene-butadiene rubber And a soft sheet made of synthetic rubber or natural rubber such as isoprene rubber or silicone rubber, or a thermoplastic elastomer such as olefin, urethane, polyester or vinyl chloride. Further, these lowermost sheets may be a plurality of laminated sheets or foam sheets. Regardless of the configuration, a soft sheet that is soft at room temperature is required. The thickness is not particularly limited, but is preferably 0.5 to 5 mm, particularly 1 to 3 m.
It is preferable that the thickness is about m, which is the same size as the hard support plate B.

The lowermost soft sheet C is provided with a plurality of convex protrusions 3 on one surface of the back surface. The convex protrusions 3 may be formed in various shapes such as providing stripe-shaped convex protrusions at equal intervals in an arbitrary direction such as a vertical direction, a horizontal direction, an oblique direction, or providing a circular or rhombus-shaped protrusion on one surface. Can be provided. Regardless of the shape of the protrusion, it is preferable that the concave groove 4 is continuously connected between the protrusion and the protrusion to the end of the mat. When a mat is laid by the continuous concave grooves 4, a water channel for muddy water, rainwater, or the like is formed, and a drainage effect for improving the flow of water is provided.

The difference between the projections and the recesses of the projections 3, that is, the depth of the groove 4 is 0.2 to 3 mm, preferably 0.3 to 1.
About 5 mm is good. The protrusion 3 is the sheet C forming the lowermost layer.
The sheet C may be provided by embossing, may be mechanically scraped, or another member may be attached to the sheet C to form the projection 3. In any method, it is preferable that the convex projection 3 is also soft and soft at room temperature. Since the convex protrusions 3 are soft, even if the mat is laid on a place such as concrete or the like where there is unevenness or unevenness of the base, the protrusions are easily crushed, so that the mating with the base can be improved.

The fiber cord 1 buried in the rubber layer 2 of the rubber simple substance a in the rubber mat A forming the surface of the present invention is mainly made of nylon fibers (polyamide fibers), but is made of other fibers such as polyester fiber cords. There is no particular limitation as long as it is used as a tire cord. The fiber cord 1 is buried in the rubber layer 2 in a state of being raised substantially perpendicularly to the mat surface, and its tip protrudes from the rubber layer 2 and is fluffed. The mat surface is tightly covered by this fluffy fiber cord 1, forming a cut pile carpet-like surface. The length of the fiber cord protruding from the rubber layer is 0.1
10 to 10 mm, preferably 0.5 to 5 mm is good.
The thickness of the rubber layer in which the fiber cord is embedded is 3 to 30.
mm, preferably 5 to 10 mm.

The rubber simple substance a is cut from old tires such as aircraft, buses and trucks, and has a limited size. Usually, the width is 5 to 50 mm and the length can be up to about 10 m. This is cut into a strip having a length of 100 to 1000 mm, and a large number of the rubber simple bodies a are provided side by side without spacing, and the back surface of these rubber simple bodies a is impregnated with rubber. And is fixed to the surface of the base material b such as the base cloth. Thus, the strip-shaped rubber simple substance 1
To form one rubber mat A of an arbitrary size. In this case, it is optional whether the strip-shaped rubber simple substance a is arranged in a single row or a plurality of rows so as to be in the same direction or alternate directions, and is adhered and fixed to the surface of the base cloth b. Further, the strip-shaped rubber single bodies 1 are not directly bonded and bonded, and the gap between the strip-shaped rubber single bodies of the mat has an effect of further improving the slip resistance.

The base material b such as a base cloth for supporting the rubber simple substance a is preferably formed by impregnating with a liquid rubber, but may be formed by impregnating with a liquid synthetic resin such as a vinyl chloride paste or a base cloth and a rubber. Or a laminate of a synthetic resin sheet and a base material that can support the strip-shaped single rubber 1 without any particular limitation.

The back surface of one or more rubber mats A and the support plate B are preferably joined to each other by using a strong adhesive having good adhesion to each other, such as nitrile rubber, chloroprene, urethane, and the like. Polyester adhesives are preferred. Further, the bonding between the support plate B and the flexible sheet C is performed by using an adhesive such as an epoxy-based, urethane-based, polyester-based, or nitrile rubber-based adhesive, or both the support plate B and the flexible sheet C are dissolved. Bonding may be performed by welding with an organic solvent such as tetrahydrofuran or the like. Alternatively, the peripheral portion may be welded with a width of about 30 to 50 mm using a solvent, and the remaining central portion may be bonded with an adhesive.

Next, a specific embodiment of the present invention will be described in detail. Nylon fiber cord is buried, and the cord tip protrudes about 0.5 mm from the rubber layer and is fluffy, 7 m thick
A set of 25 strip-shaped rubber pieces having a length of 254 mm in length and width bonded to the rubber-impregnated backing fabric on the back side is formed by arranging 25 strip-shaped rubber pieces having a length of 254 mm in length and a width of 254 mm. Four mats are placed side by side at right angles to each other, and a hard vinyl chloride plate of 500 mm in length and 2 mm in thickness is bonded to the back surface of the mat with a chloroprene rubber-based adhesive so that a 4 mm plateless portion is formed around the mat. Was.

Next, one side is embossed in a stripe shape in parallel at intervals of 4.5 mm in a thickness of 1.3 mm, 500 m in length and width.
The non-embossed surface of the soft vinyl chloride sheet m was solvent-welded to the hard vinyl chloride plate on the back of the rubber mat with tetrahydrofuran to prepare a mat of the present invention.

Although this was laid on concrete with uneven land, the mat was not displaced even when humans walked.
Also, the mat was well adapted to the concrete surface, and the end of the mat did not float. Further, when water was sprayed around the mat, there was no problem that the water was drained from the groove on the back surface and water accumulated around the mat.

[0019]

[Effect of the Invention] The mat according to the present invention does not need to be bonded to the base such as concrete through an adhesive as in the prior art, so that the workability is improved, and the mat back surface is made of a soft material having a soft projection. Because it is a sheet, it is very familiar even if the concrete has irregularities despite the work of simply putting it on, the mat does not expose and the edges do not float, so people can walk There is no deviation.
In addition, the gap between the strip-shaped rubber pieces alone of the mat can further enhance the slip resistance.

Further, rainwater and muddy water around the mat are drained from the groove between the convex projections, and water does not accumulate around the mat as in the conventional case. A hard support plate is provided on the mat intermediate layer, so that the rubber mat does not shrink or warp, and since the support plate has an appropriate flexure, it has a good conformity with a base material such as concrete and has a soft back surface. The end of the mat does not float together with the sheet.

Since the mat is not adhered to a base such as concrete as in the prior art, if the mat becomes dirty, it can be removed and cleaned, or only the mat in the soiled portion can be replaced.
