Therefore, in use, the air tube can be expanded to a predetermined diameter to prevent foreign matter from penetrating, and during storage, the air tube can be contracted and folded in a flat state.

Description

Mat for foreign matter measures {FOREIGN SUBSTANCE RESISTANT MATTING}

The present invention relates to a mat for countermeasures against foreign matters, and more specifically, a mat for foreign matter countermeasures provided with an air tube along the periphery of an expandable and retractable air tube to prevent contamination of the upper surface by foreign matters such as soil and sand during outdoor use. It is about.

Mats of this kind are generally made of foamed resin, and thin films are bonded on the upper and lower surfaces to impart waterproofness, rigidity and toughness, respectively. Therefore, the mat made of foam resin has an advantage of being light and easy to be folded and stored due to the characteristics of the molding material. Because of these advantages, mats made of foamed resin have been widely used.

When the mat made of the foamed resin is used outdoors, for example, on the beach, at a river, etc., the mat is light in weight, and thus tends to deviate from its original position due to a breeze or a strong wind. In addition, the mat spread outdoors has a problem that the upper surface is soiled by foreign substances such as soil, sand, etc. caused in the process of inadvertently taking off or wearing shoes of a young child.

In order to solve the above-mentioned problems, the present invention relates to a mattress for preventing foreign matters equipped with an air tube along the periphery of an expandable and retractable air tube to increase the wind resistance and prevent foreign matter from penetrating into the upper surface.

Therefore, the mat according to the present invention has a height several tens of times higher than the thickness of the main body through the injection of air when used by the air tube installed on the outer periphery, while the storage is almost the same thickness as the main body through the discharge of air. Characterized in having a.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 shows, in perspective view, a mat having an inflatable and retractable air tube according to a preferred embodiment of the present invention. The mat 10 is formed of a main body 11 formed of a foamed resin, an upper paper 13 bonded to an aluminum film on an upper surface of the main body, and a lower paper 15 bonded to a polyethylene film on a lower surface of the main body. Equipped. The outer periphery of the mat is equipped with an air tube 20 that can continuously expand and contract. Optionally, this air tube 20 may be discontinuous.

The mat main body 11 made of the foamed resin is preferably molded from foamed polyethylene having excellent processability and foamability. The upper paper 13 is an aluminum film that can withstand rupture, and optionally may be a fabric coated with reinforcing fibers to provide a predetermined rigidity. The Habakji 15 is a polyethylene film having resistance to microorganisms in outdoor soil, waterproof and moisture-proof. In addition, in order to bond the upper and lower paper to the main body, it is preferable to use a polyethylene resin solution in a gel state as an adhesive.

Referring now to FIG. 2, the air tube 20 is made of a polymer material such as polyvinyl to give flexibility. However, the air tube may be made of a material having a density almost similar to that of the main body in consideration of the total weight of the mat. The air tube 20 is preferably attached by ultrasonic fusion with a predetermined width along the outer circumference of the main body 11. In addition to this, a method of attaching by sewing, a method of attaching by an adhesive, or a combination thereof that is commonly used in the prior art is also possible.

The air tube 20 has an attachment portion 21 for attaching to the main body 11 of the mat with a predetermined width, a hollow body 23 formed integrally with the attachment portion, and installed at an arbitrary point of the body. And a valve 25 for injecting or discharging air. Like the check valve, this valve 25 is provided with a non-return valve which prevents any discharge during the injection of air, and a stopper for opening and closing the air injection passage. After the user removes the plug from the air inlet of the valve, the user presses the vicinity of the non-return plate with one hand, and the air contained in the hollow body of the air tube 20 is discharged. Valves with air injection and discharge characteristics in this manner are readily available on the market. Therefore, detailed configuration and description of the valve is omitted here.

The attachment portion 21 of the air tube has a width in the range of 2-3 cm. The hollow body 23 may overlap the polymer film in a plurality of layers, or may be reinforced by a mesh-like fiber between these layers. Accordingly, the hollow body 23 can be prevented from being torn by an object or the like during use outdoors. The valve 25 is mounted at the required point in the hollow body, preferably near the edge of the mat body.

On the other hand, the manufacturing process of the air tube 20 is almost similar to the manufacture of an air tube-type advertising article or life tube. Therefore, the manufacturing process of the air tube will be described briefly here, and may be sufficiently performed by other known processes. First, a thin sheet-like sheet is manufactured by a plastic material. The sheet is cut by a length corresponding to the same dimensions as the mat body, for example, the length of both the predetermined horizontal and vertical lengths combined. The preassembled valve is attached at a suitable point in the sheet thus cut. Then, the seat on which the valve is mounted is bonded by a heat fusion method, a bonding method using an adhesive, or the like in a state in which both sides are facing each other along the longitudinal direction, and the ends at both sides in the longitudinal direction are also bonded by the same method. As a result, the inner space except for the bonded both sides and the end portion serves as an inflatable hollow body by air.

When air is injected through the valve 25 of the air tube, the air tube 20 is expanded to a predetermined diameter at the outer circumference of the mat body 11. When this air tube 20 is inflated to a certain pressure, its final shape is circular or elliptical. At this time, the final expansion diameter of the air tube is about 8 to 15 cm is suitable, but it will be apparent that this range is only a value selected appropriately according to the use environment of the mat. On the contrary, when the air escapes through the valve of the air tube 20, the air tube 20 maintains a thickness almost the same as that of the main body. In this state, the mat is folded in a predetermined order and is in a state for storage.

The mat 10 according to the present invention is the same in that it can be folded for storage after being used outdoors in comparison with the mat of the prior art, but in that the air tube is mounted along the outer periphery of the main body 11. Different.

In addition, the air tube 20 installed in the mat according to the present invention may be disposed continuously along the outer periphery of the mat main body 11, or may be optionally arranged discontinuously. In other words, the air tube 20 may be attached in various parts along the outer periphery of the body, preferably in a divided state near the edges. In this case, the air tube is made shorter, the waste of material can be suppressed as much as possible, and further, the air can be rapidly injected or discharged into each divided air tube.

According to the mat according to the present invention, when the air tube provided on the outer periphery of the mat is expanded, a phenomenon occurs in the mat of the prior art, that is, the soil, sand to the upper surface of the mat in the process of inadvertently taking off the shoes or playful children Penetration of foreign matter such as this can be effectively prevented.
