Description

floor mats {IMPACT ABSORPTION MAT}

The present invention relates to a floor mat, and more particularly, it can protect children's safety from various impacts by installing it on an indoor floor of a daycare center, an outdoor floor of a children's playground, etc. It's about floor mats.

In general, in daycare centers or children's playgrounds, safety is the most important aspect, so the floor must have good shock absorption and not slippery to prevent safety accidents.

Therefore, the recent indoor floor of a daycare center or an outdoor floor of a children's playground is a floor mat made of a rubber material that is safe and has excellent elasticity in consideration of safety as well as sanitary issues.

Usually, the mat unit is installed on the floor of a living room, office, or playroom or gym to use as the main purpose of insulation and cushioning. Depending on the intended use, the function and material of the mat unit to be installed can be used.

Among them, recently, a mat composed mainly of a foam sponge (EVA form: ethylene-vinyl acetate copolymer) is mainly used, which is rich in elasticity, has excellent absorbency, is light in weight, soft to the touch, and has high thermal insulation and elasticity. Due to its good airtightness, it is mainly used in places where children's skin is in direct contact, such as the floor of a playroom or study room. am.

However, mats produced from the above materials have low durability, so when used as a puzzle mat, it is not easy to combine and separate each mat, and at this time, the mat connection part is damaged or the mat itself is bent or pressed during long-term use. It cannot be used for a long period of time due to deformation caused by deformation, especially the lifting of the edge of the mat. In the event of a particularly strong impact, the mat absorbs some of the impact, but the impact is transmitted to the floor and used in the balcony or living room of the apartment. There is a problem in that the impact sound is transmitted to the lower part, and the noise and vibration are transmitted to the lower floor.

In addition, when used on the floor of a gymnasium or on a sidewalk (walking path, bicycle path), etc., it cannot be used due to insufficient durability.

Meanwhile, among the conventional floor mats, there is a floor mat having a wire mesh inserted therein, but in this case, the wire mesh inside is bent or pressed together with the mat having cushioning properties, and the reinforcing structure using the wire mesh, such as failing to fulfill its role. The furnace has insufficient points in preventing the deformation of the mat, especially the lifting of the corners of the four mats.

It is characterized in that it is designed to prevent the phenomenon of floating and lifting.

Here, as an example of the reinforcing member, four bars made of a wood material are formed into a square frame-shaped weave structure, and grooves are machined at both ends of each bar, and the grooves of each bar in contact with each other in the shape of a square frame are mutually coupled. By doing so, the four rods can form a quadrangular frame-shaped weaving structure.

And, as another example of the reinforcing member, one bar made of a metal material, for example, an aluminum material, and at the same time having a "B"-shaped cross section is formed in an integral structure in the form of a square frame, but three of the bars are After forming a square frame by bending 90°, one bar can form an integrated structure in the form of a square frame by connecting the ends of both sides that are in contact with each other with welding.

As a preferred embodiment, the reinforcing member is covered by the synthetic resin material that becomes the material of the upper mat in a state that is placed on the lower mat after forming the lower mat, and when the upper mat is formed while the synthetic resin chip is compressed, They can be insert molded together on the inside of the top mat.

The floor mat with a built-in reinforcing member of the present invention is provided with a frame-structured reinforcing member with a predetermined rigidity inside the exterior plate formed of a conventional foam sponge (EVA form), while maintaining the existing elasticity and soft contact properties.

To this end, the floor mat is made of a laminated combination structure of the upper mat 10 and the lower mat 11 made of a synthetic resin material or the like.

The upper mat 10 and the lower mat 11 are in the form of a square plate, and can be manufactured using conventional waste tire rubber chips. After pulverizing waste tire chips or various rubber resins, a resin curing agent is pulverized. A method of mixing with a resin and then melting it and molding it into a desired shape through a mold, for example, putting a rubber chip, which becomes a lower mat material, into a mold and pressing it to prepare the lower mat 11, and then the upper mat material on it In a laminated state, the rubber chips are also put in a mold and pressed to form a lower mat 11 and an integral upper mat 10 .

As the upper and lower mats 10 and 11 manufactured in this way are made of rubber and thermoplastic resin with high elasticity and durability, they can exhibit an excellent shock absorption function, as well as recycling of resources by using waste tire rubber chips. environmental pollution can be prevented.

At this time, the upper mat 10 is molded into a plate shape by mixing a rubber chip with a size of about 1 to 2 mm and a curing agent to maximize the elasticity, and the lower mat 11 has a size of about 5 to 6 mm. By mixing the rubber chip with a curing agent, it can be molded in a laminated state.

Accordingly, since the size of the rubber chip of the upper mat 10 is about 1 to 2 mm, the durability can be improved due to the uniformity of the entire surface, such as being able to maintain a close state, and the lower mat 11 is the size of the rubber chip. Since the size is about 5-6 mm, it is possible to maximize the elasticity while supporting the upper mat 10 .

Here, a method of integrally dipping an upper mat and a lower mat by a press molding method using a mold and the like may be adopted without particular limitation as long as it is a method commonly known in the art.

In addition, a plurality of drainage grooves 12 are formed on the bottom surface of the lower mat 11 in the shape of a square groove, and the drainage grooves 12 at this time are five and ten over the entire mat area. can be arranged accordingly.

These drainage grooves 12 not only perform a function of draining water flowing through the floor of a children's playground, etc., but also the drainage grooves 12 in the shape of each independent square groove can also perform an air pocket function. , therefore, the drain groove 12 can absorb and buffer the impact force from the outside, and at the same time the upper and lower mats 10 and 11 can exert a restoring force that can smoothly return to the original state after being pressed. Not only can it prevent the risk of being sunken into the body, but it can also double the elasticity, durability, and shock absorption.

In particular, the reinforcing member 13 made in the form of a square frame is built inside the upper mat 10, and the upper mat 10 and the lower mat 11 due to the rigidity exerted by the reinforcing member 13 built in this way. Deformation of the entire floor mat including It is possible to prevent shrinkage of the mat due to change.

For example, after processing the grooves 13b at both ends of each of the four bars 13a, and arranging the four bars 13a having the grooves 13b at both ends in this way in the form of a rectangular frame, the rectangular frame at this time By fitting the upper and lower grooves 13b of each bar 13a in contact with each other while partially overlapping in shape, the four bars 13a can be made into the reinforcing member 13 constituting a quadrangular frame-shaped fitting structure.

In addition, the reinforcing member 13 is inserted together during compression molding of the upper mat 10 so that it can be formed to have a structure embedded in the upper mat.

For example, after molding the lower mat 11 in the form of a square plate, the reinforcing member 13 woven in the form of a square frame is placed on the upper surface of the lower mat 11 in a coaxial structure, and then the mold (not shown) is continued. The reinforcing member ( 13) can be insert molded together.

That is, when the upper mat 10 is integrally formed on the lower mat 11, the reinforcing member 13 is inserted so that the upper and lower mats 10 and 11 and the reinforcing member 13 can be integrally molded together. .

By applying the method of insert molding and embedding the reinforcing member 13 together during the molding of the upper mat 11 and the lower mat 11, the upper and lower mats 10, 10, 11) and the reinforcing member 13, it is possible to manufacture an integrated floor mat.

At this time, the reinforcing member 13 is made of a relatively small size (square area) compared to the size (square plate area) of the upper and lower mats 10 and 11 in the form of a square plate, and the upper and lower mats 10 and 11 It can be arranged along the inner square periphery adjacent to the edge of the, and the reinforcing member 13 arranged in this way is out of the position of the drainage groove 12 formed in the lower mat 11, for example, the drainage groove ( 12) and the drain groove 12 can be positioned where there is a mat part.

Accordingly, while the reinforcing member 13 in the shape of a square frame capable of exhibiting its own rigidity is built inside the upper mat 10, that is, in the inside of the floor mat, the reinforcing member 13 at this time is in the form of an overall square plate of the floor mat. In the end, this reinforcing member 13 reinforces the rigidity of the floor mat, in particular, the rigidity of the corner portion of the floor mat, thereby preventing deformation such as twisting of the floor mat or lifting of the corner portion. there will be

In addition, a plurality of drainage grooves 12 are formed on the bottom surface of the lower mat 11 in the shape of a square groove, and the drainage grooves 12 at this time are five and ten over the entire mat area. can be arranged accordingly.

These drainage grooves 12 not only perform a function of draining water flowing through the floor of a children's playground, etc., but also the drainage grooves 12 in the shape of each independent square groove can also perform an air pocket function. , therefore, the drain groove 12 can absorb and buffer the impact force from the outside, and at the same time the upper and lower mats 10 and 11 can exert a restoring force that can smoothly return to the original state after being pressed. Not only can it prevent the risk of being sunken into the body, but it can also double the elasticity, durability, and shock absorption.

In particular, the reinforcing member 13 made in the form of a square frame is built inside the upper mat 10, and the upper mat 10 and the lower mat 11 due to the rigidity exerted by the reinforcing member 13 built in this way. It is possible to prevent deformation of the entire floor mat, including, for example, the opening of the upper and lower mats 10 and 11, distortion of the corners of the upper and lower mats 10 and 11, or the lifting phenomenon.

To this end, the reinforcing member 13 is made of a metal material such as aluminum or iron and at the same time has a structure in which one rod 13c of a certain length having a "B"-shaped cross-section is bent into a rectangular frame shape. do.

For example, by bending 90 ° at three places of the rod 13c to form a square frame, and then welding the ends of both sides in contact with each other and then attaching them, that is, by joining the ends in contact with each other with a welding part 13d By giving, one rod 13c can be made of the reinforcing member 13 forming an integral structure in the form of a square frame.

In addition, the reinforcing member 13 is inserted together during compression molding of the upper mat 10 so that it can be formed to have a structure embedded in the upper mat.

For example, after molding the lower mat 11 in the form of a square plate, the reinforcing member 13 woven in the form of a square frame is placed on the upper surface of the lower mat 11 in a coaxial structure, and then the mold (not shown) is continued. The reinforcing member ( 13) can be insert molded together.

That is, when the upper mat 10 is integrally formed on the lower mat 11, the reinforcing member 13 is inserted so that the upper and lower mats 10 and 11 and the reinforcing member 13 can be integrally molded together. .

By applying the method of insert molding and embedding the reinforcing member 13 together during the molding of the upper mat 11 and the lower mat 11, the upper and lower mats 10, 10, 11) and the reinforcing member 13, it is possible to manufacture an integrated floor mat.

At this time, the reinforcing member 13 is made of a relatively small size (square area) compared to the size (square plate area) of the upper and lower mats 10 and 11 in the form of a square plate, and the upper and lower mats 10 and 11 It can be arranged along the inner square periphery adjacent to the edge of the, and the reinforcing member 13 arranged in this way is out of the position of the drainage groove 12 formed in the lower mat 11, for example, the drainage groove ( 12) and the drain groove 12 can be positioned where there is a mat part.
