The present invention relates to the structural design of a floor mat, and has a non-slip effect at the bottom and a ventilation function between the bottom and the contact surface. The entire mat is suitable for a floor mat in an automobile car and a rear trunk mat from the upper layer to the lower layer, and is flat. The present invention relates to a floor mat suitable for use in a building or room entrance / exit floor mat, a yoga mat for exercise, or other similar purposes.

Common mats are mostly placed on the floor and used to clean feet and step on dirty shoes when people come and go in various places. For example, when entering the indoor from the outside, if you step on the entrance mat with shoes, the mud on the bottom of the shoe will fall and remain on the mat, and mud will not enter the indoor and can be kept clean. Further, when the user comes out of the bathroom with the floor wet, if the user steps on the mat, the moisture on the soles is absorbed and the moisture on the soles disappears, so the danger of slipping and falling can be avoided. Alternatively, when the floor mat laid on the floor of the automobile enters the vehicle from the outside of the vehicle, dirt on the shoe sole can be removed on the mat, and thereafter the vehicle interior environment can be kept clean simply by cleaning the mat.

There are various materials for floor mats and foot-wiping mats because they are used for different purposes. For example, mats that are used indoors can be used as simple materials such as cloth and carpet materials that can quickly absorb moisture. Some are made of a single material, and in order to maintain the mat's anti-slip property, an anti-slip structure is provided under the mat cloth to obtain an anti-slip effect.

The design of various mats requires an anti-slip function in order to maintain safety, and in the manufacture of mats, considering the convenience and cost at the time of manufacture, the product structure is solid and beautiful. It must be affordable.

The main object of the present invention is to provide a floor inside an automobile, effectively having a non-slip function on the bottom surface of the mat, and water absorbed by the entire mat surface does not soak into the bottom portion, and the entire mat is waterproof. The object of the present invention is to provide a floor mat for use in the entrance / exit floors and exercise floors of rooms and buildings.

Another object of the present invention is composed of a three-layer material, and does not require an adhesive solvent for bonding between the material layers, and not only has a strong bond, but also has a solvent that exists in the human body. It is intended to provide a floor mat used for a car interior floor, an entrance / exit floor of a room or a building, an exercise floor, etc., which is excellent in environmental protection characteristics.

Still another object of the present invention is to cut into different dimensions and contours according to the needs of the scene to be used, such as automobile floor mat, automobile rear trunk mat, room / building entrance / exit floor mat, exercise mat, etc. An object of the present invention is to provide a floor mat that can be used for a car interior floor, an entrance / exit floor of a room or a building, and an exercise floor.

In order to achieve the above-mentioned object, the mat design of the present invention is such that the mat body includes a three-layer material, and includes an intermediate layer, an upper layer, and a lower layer, and an additional adhesive solvent or adhesive is added through lamination bonding. There is no need, and the intermediate layer is a relatively thick crosslinked polyethylene foam board (Cross-linked
Polythene foam) or EVA (Ethylene Vinylacetate Copolymer) foam board, and the upper layer is woven fabric, non-woven fabric, tufted carpet with durability
carpet), woven carpet or anti-slip thermoplastic rubber (TPR) layer or thermoplastic elastomer (TPE)
The lower layer is a thin layer of thermoplastic rubber (TPR) which has an anti-slip effect. The three-layer composite mat body can be cut to an appropriate size and contour, and is heated and softened in an oven, pressed into a mold and pressed into a raised edge with a raised rim. It is possible to provide a floor mat to be used on a floor in an automobile and a rear trunk mat. In addition, after softening by heating, it is placed in the mold and three-dimensional dents and protrusions are formed on the mat surface, increasing the coefficient of friction for contact with the other surface of the mat and improving the anti-slip function. May be.

Other features and specific embodiments of the present invention will be described below in detail with reference to the drawings.

As shown in FIGS. 1 to 3, the mat of the present invention is composed of a three-layer material, and includes an upper layer 10, an intermediate layer 20, and a lower layer 30. The upper layer 10 is a durable woven fabric, nonwoven fabric, and tufted carpet. (tufted carpet), needle-woven carpet, anti-slip thermoplastic rubber (TPR) layer, thermoplastic elastomer (TPE: thermoplastic)
The upper layer must have aesthetics, anti-slip effect, and abrasion resistance, and woven fabric, non-woven fabric, tufted carpet (tufted carpet)
carpet), needle-woven carpet, etc., and it is possible to express the texture and fine aesthetics with cloth and carpet materials, and to obtain a slightly lower anti-slip effect, and considering anti-slip properties, thermoplastic rubber ( TPR: thermoplastic
It may be a rubber) layer or a thermoplastic elastomer (TPE) layer, which can form an excellent toughness and wear resistance and can protect the intermediate layer. The intermediate layer 20 should be a relatively thick plate material that gives comfort to the entire mat, and at the same time, the intermediate layer should be light and water-absorbent and capable of molding and maintaining the contour of the mat. (Cross-linked
Polythene foam) or EVA (Ethylene Vinylacetate Copolymer) foam board. Since the lower layer 30 must have an anti-slip action, an anti-slip thermoplastic rubber (TPR: thermoplastic)
A thin layer made of rubber).

As shown in FIG. 2, the intermediate layer 20 is made of a thermoplastic foam board having a relatively large thickness, and the thickness of the material should be between about 3 mm to 6 mm based on experience, and the mat is light and absorbs vibration. Characteristics such as performance, soundproofing, waterproofing, elasticity, and comfort, and the weight of the entire mat can be reduced to improve convenience in carrying. When the upper layer 10 is overlaid on the upper surface of the intermediate layer 20, the material of the upper surface of the intermediate layer 20 foamed plate is heated at high temperature with a flame, the surface portion is softened and the surface showing a viscous state is melted. Since the upper layer 10 and the intermediate layer 20 can be bonded by roller pressing, it is not necessary to add an adhesive solvent or an adhesive to the adhesive.

The upper layer 10 is a thermoplastic rubber (TPR) layer or a thermoplastic elastomer (TPE).
elastomer and the thermoplastic rubber (TPR) layer or thermoplastic elastomer (TPE: thermoplastic)
An elastomer (elastomer) layer is extruded in a molten state and applied to the upper surface of the intermediate layer 20, and the thermoplastic rubber (TPR) layer or thermoplastic elastomer (TPE)
When the elastomer is still in the melted state, it has viscosity, so it can be bonded to the intermediate layer 20 without the need for adding an additional adhesive solvent, and the upper layer 10 and the intermediate layer 20 can be bonded more closely with a roller press. Can do. For this reason, the upper layer 10 is durable woven fabric, non-woven fabric, tufted carpet (tufted carpet)
When a textile fiber material such as carpet) or a needle-woven carpet material is employed, it can be bonded to the upper surface of the intermediate layer 20 to form a slight anti-slip action, and at the same time an excellent texture can be obtained. In addition, the upper layer 10 is made of thermoplastic rubber (TPR: thermoplastic).
If a rubber or thermoplastic elastomer (TPE) layer material is used, an excellent non-slip layer will be formed after cooling, avoiding the risk of slipping on the sole or sole of the upper layer The safety can be ensured, and the layer can protect the intermediate layer and make the entire mat durable. The upper layer 10 and the intermediate layer 20 are bonded by a cold roller press to completely bond the upper layer and the intermediate layer into one piece, and the length of the piece is several tens of centimeters to several meters long. If the material is long when the upper layer and intermediate layer materials are pressed, it can be made into a continuous state in the form of a roll so that it can be conveniently stored and transported.

Further, the intermediate layer 20 and the lower layer 30 are bonded to each other by the extrusion technology (Extrusion) technique.
When the rubber layer is applied to the lower surface of the intermediate layer 20 and the thermoplastic rubber (TPR) layer of the lower layer 30 is extruded, it has viscosity when it is still in a molten state. It can be combined with the intermediate layer 20 without the need for addition, and a relief design is made on the composite of the intermediate layer 20 and the lower layer 30 using roller lamination (TPR: thermoplastic).
An anti-slip layer is formed after the thermoplastic rubber (TPR) layer is cooled on the surface of the rubber layer. The thermoplastic rubber (TPR: thermoplastic
rubber) layer has the softness and elasticity of rubber and anti-slip action, and can further increase the coefficient of friction when the relief design comes into contact with the floor board, enhance the anti-slip effect, and The relief design forms irregular irregular air spaces with the contact surface, so the minute gap between the contact surface improves the air permeability of the mat and the contact surface, making it difficult to generate mold, etc. It can meet hygiene requirements.

This mat structure is a composite structure in which three layers are combined, and can be cut into specific contours, dimensions, and shapes, placed in an oven, softened by heating, and then placed in a mold.
