Description

Individual mat for assembly, and assembly mat having the same (element mat for assembly and assembled mat having the same}

The present invention relates to a prefabricated mat, and more particularly, to protect children from falling even if they fall by laying on the floor of the room, or to prevent inter-floor noise from occurring in a multi-story building such as an apartment, and a combination thereof. It relates to a buildable mat.

Cushion mats are used in general homes and multipurpose facilities such as kids cafes and nursing homes for the purpose of preventing falls, preventing noise between floors, preventing musculoskeletal diseases and alleviating fatigue in places such as kitchens.

Cushion mats are often formed to cover a large area by simply assembling protrusions and grooves that engage with each other around small square or rectangular individual mats to facilitate installation and removal as needed.

1 shows such a conventional example. As viewed from above, the four sides of the square plate-shaped body (1) are formed by alternately forming coupling grooves (3) and protrusions (4) with diagonal lines on each side (2) at regular intervals. According to the area of, a plurality of protrusions are assembled and laid in a manner that connects the protrusions to the coupling grooves in all directions.

In this case, if the connecting portion of the coupling groove and the protrusion is viewed as a zigzag complex line, the eyes are easily fatigued, and as the length of the connecting portion is longer, there are many gaps where foreign substances such as dust are trapped, so cleaning, etc. There were also problems such as taking a lot of time and effort to manage.

2 shows another conventional example. Also, coupling grooves and protrusions are formed on the four sides of the square body, but the coupling grooves and protrusions are not formed in the entire thickness of the body, but are formed only in the lower half of the body, and are not formed over the entire side, but are formed only in a portion of the body. The coupling grooves and protrusions are not visible from the top, resulting in a more stable appearance.

However, all of these prefab mats are usually made of polyurethane foam for their own purposes, so they are soft and stretchable, so when pressure or force is applied to the assembly connection, the gap is easy to open, and if water or beverage falls on the mat, it seeps into the gap and gets wet. There is a risk of damage such as rotting or deforming the floor under the roof. Dust can also enter the gap, and if the user steps on the excitement space of the mat and floor during activity, compressed air can come out of the gap and exhale dust.

In addition, a gap is formed over the entire thickness, and if only one side of the assembly connection of two adjacent mats is pressed, a step may occur and a foot jam may occur.Adults do not have a big problem, but the child's fingers and toes are caught in the gap. There may be a problem of safety accidents such as tripping or in severe cases causing a fracture of the finger toe.

Due to the characteristics of the mat made of pole material, the coefficient of contraction and expansion according to temperature is large, but if the structure does not have enough force to hold the connection between the mats, there is also a problem that gaps between the mats may occur depending on the temperature even if there is no external force. .

To avoid this problem, treating the assembly joints and floors with adhesive materials may lose the benefits of the assembly mat, make installation and removal work cumbersome, and damage the floor.

If a force is applied to the side to keep the mat close to the adjacent mat during construction in order to suppress the phenomenon of the gaps in the assembly connection part, body deformation may occur and the gap with the floor may float, and the appearance may be poor.

Korean Patent Publication No. 10-2015-0103416: Assembly mat Japanese Patent Publication No. 2011-247026: Joint mat

The present invention is to solve the problems of the conventional prefabricated mat, it is an object of the present invention to provide a prefabricated mat that is easy to install and that can prevent the lifting phenomenon after installation or installation.

An object of the present invention is to provide a prefabricated mat capable of reducing the problem of fractures or sprains in which children stumble due to a step of the assembly connection part after installation, or children's fingers or toes enter through a gap.

An object of the present invention is to provide a prefabricated mat having a configuration that allows moisture or dust to enter the gap of the assembly connection part and damage the floor after installation, and to easily find and remove moisture or dust.

Individual mat for assembly of the present invention to achieve the above object

In the individual mat for assembly made of a polygonal plate, on the side of the individual mat for assembly over the entire side of the polygon (the entire section), a step portion consisting of grooves and protrusions for bonding with an adjacent individual mat is installed below the thickness direction. , A step groove extending long along the side is installed on an upper surface facing the top of the protrusion, and a step protrusion fitted to fit the step groove is installed on a corresponding surface facing the bottom of the groove.

In the present invention, the grooves or projections of each side of the individual mat for assembly may be installed to be mutually coupled with the projections or grooves of the sides adjacent to the respective sides of the same assembly individual mat placed on the floor in the same phase. One protrusion may be formed in a half section of the side and a groove may be formed in the other half section.

In the present invention, at least one protruding jaw is installed in the stepped groove, and a protruding jaw groove is installed at a position corresponding to the protruding jaw in the stepped protrusion, so that movement in the lateral direction between individual mats with sides coupled to each other can be suppressed. Preferably, the protruding jaws are installed at both ends of the stepped groove, so that the stepped groove may form a shape like a small container that can contain water or dust.

In the present invention, the body of the individual mat for assembly is preferably made of a porous foam material such as polyurethane foam to help sound absorption and vibration prevention, and is formed of a synthetic resin or rubber material with elastic and soft material to protect children. It is preferable, and at the same time, it is preferable to have a mechanical strength capable of maintaining constant durability.

In the present invention, the upper surface of the individual mat for assembly may be formed of a material having different characteristics, such as a polyurethane film such as TPU (thermo plastic polyurethane), which is harder than the polyurethane foam and is not easily damaged.

In the present invention, a nonwoven fabric layer, an adhesive layer, etc. may be additionally formed on the bottom of the individual mat for assembly as required.

In the present invention, the protrusion thickness or groove depth of the stepped portion of the individual mat for assembly may range from 1/4 to 3/4 of the thickness of the individual mat.

In the present invention, at least a part of the side surface of the individual mat including the stepped portion may be treated to be water-repellent or waterproof through a coating film or a film treatment, or may be treated to adsorb foreign substances such as fine dust or dust. At this time, a viscous material layer may be used for adsorption of foreign matter.

In the present invention, the entrance of the step groove is formed narrower than the maximum width section of the step groove, so that when it is combined with the stepped protrusion of a corresponding shape, it is coupled by force fitting, and when spaced apart, it can act as a locking jaw.

The prefabricated mat of the present invention consists of two or more individual mats for assembling of the present invention by connecting grooves and protrusions to each other in a polygonal side and connecting them in a lateral direction.

According to the present invention, it is not necessary to assemble a separate lateral force around the periphery during construction, so that the installation of the prefabricated mat is facilitated, and the lifting phenomenon can be prevented during the installation process or after installation.

According to the present invention, since grooves and protrusions are installed in the lower thickness over the entire periphery, the depth of the gap is reduced, so after installation, children trip over due to the step of the assembly connection part, or the children's fingers or toes enter into the gap and cause a fracture or sprain. Can be reduced.

According to the present invention, since grooves and protrusions are installed in the lower thickness over the entire periphery, and water or dust is highly likely to be blocked by the upper surface grooves of the protrusions that are installed long in the lateral direction, moisture or dust enters the gap of the assembly connection part You can control offending problems and increase the likelihood of finding and removing moisture or dirt.

Hereinafter, the present invention will be described in more detail through specific examples with reference to the drawings.

3 to 5 illustrate a plan view of a combined state of two adjacent individual mats, a perspective view of a proximity state, and a partial cross-sectional view of the mated state according to an embodiment of the present invention.

Here, the individual mats 10 and 20 are all formed in the same shape and may be combined with adjacent individual mats in the same phase, that is, in the same state in which the upper and lower positions and the rotational positions are the same. Specifically, projections 11 and grooves 17 are provided on each side corresponding to the four sides of the square body part by half sections when viewed in the side length direction. These protrusions 11 and grooves 17 are not formed on the entire side that constitutes the side, but are formed only in steps corresponding to the lower half thickness in the individual mat thickness direction.

In more detail, the protrusion 11 of the stepped portion is in the form of a plate that protrudes approximately in the right half section when each side of the square is placed above the plan view, and the groove 17 is a protrusion 21 of another individual mat in the left half section. It is installed as a concave space of a corresponding shape so that it can be connected to.

Two identical individual mats 10 and 20 formed in this way are placed adjacent to each other left and right on the floor, and the protrusions 11 of the right individual mat 10 at the sides facing each other while deforming by applying force using the elasticity and elasticity of the individual mats The protrusion 21 of the left individual mat 20 is coupled to the groove 17 of the right individual mat 10 in the groove 27 of the left individual mat 20.

The upper surface of the protrusion 11 is formed with a step groove 13 long along the length direction of the side, and a stepped protrusion 29 corresponding to the step groove 13 on the corresponding surface of the groove 27 (the surface corresponding to the upper surface) ) Is formed. The stepped protrusion 29 is formed in a position and size capable of being coupled to correspond to the stepped groove 13 on the upper surface of the protrusion 11.

Both ends of the stepped groove 13 in the lateral direction are blocked by a stepped grooved jaw or a protruding jaw 15. Therefore, when the stepped protrusion 27 is fitted into the stepped groove 13, it is prevented from being blocked by the protruding jaw 15 and sliding along the stepped groove 13 in the side direction.

The step groove 13 is in the path through which beverage or dust reaches the floor when beverage or dust enters through the gap between the assembly connection of the two individual mats, and the protruding jaws 15 at both ends have the step groove 13 If there is a small space or gap between the bottom of the stepped groove 13 and the end of the stepped protrusion 23, it is made into a kind of container that can hold an object. There is a high possibility that they will gather here without passing through the stepped groove.

Here, the protrusions and grooves formed on each of the four sides of the square individual mat are formed over the entire length (overall) of each side, but in a practical sense, it means that they are formed over each side for convenience when assembling adjacent individual mats. In the longitudinal direction of both ends of the side, for example, a case where protrusions and grooves are not formed in a section of less than 10% of the entire section can be included, and a method to avoid conflict with adjacent individual mats and facilitate assembly by rounding the shape when viewed from above. You can also use

Even in this case, the corners of the square, where the protrusions and grooves are omitted, are a small part compared to the whole, and the amount of beverage or dust that can flow into this part is limited, and it takes considerable time for beverages to flow into this part only. The low mat user can easily find and wipe spilled beverages, and if in doubt, it is possible to easily disassemble and wipe the water.

As for individual mats, polyurethane foams that are easy to expand and contract due to external force and have elasticity are often used because prefab mats are mainly used for noise prevention and cushioning functions.In this case, polyurethane foams such as TPU are used on the upper surface of polyurethane foams as individual mats. Use a coated film. Polyurethane foam has good elasticity and softness according to the required function and characteristics of the foam, but it can be easily damaged by external force and can be easily absorbed, so it is a polyurethane coating film that has a more hardness and gives a smooth appearance. This form can be made by placing a polyurethane coating film on the mold first in an insert injection method and injecting a material to form the polyurethane foam into the mold so that the foam is molded.

6 is a cross-sectional view showing in more detail the combination of protrusions and grooves of adjacent individual mats.

A stepped groove 13 a step projection 29 of the groove 27 of the distance (t ₁₁₎ is adjacent the individual mat (20) spaced apart from the body portion the main body portion of the projection 11 of each mat 10 and It is the same as the spaced distance (t ₂₁ ), and the width (t ₁₂ ) of the step groove 13 is the same as the width (t ₂₂ ) of the step protrusion 29, but the step groove of the protrusion 11 ( 13) if somewhat smaller than the body portion and the spaced distance (t ₁₁₎ is adjacent the individual mats (20) of the stepped projection (29) the distance (t ₂₁ spaced apart from the main body portion) of the groove (27) stepped groove and the level difference If the protrusions are joined without gaps, the body parts of the adjacent individual mats 20 are combined with the individual mats 10 in a somewhat compressed state at the assembly connection part when combined, and the assembly connection of the two individual mats 10 and 20 The gap does not easily open.

Likewise, if the width t ₁₂ of the step groove 13 is slightly smaller than the width t ₂₂ of the step protrusion 29, the step protrusion is compressed and fits into the step groove so that the coupling force between the step groove and the step protrusion becomes stronger. I can.

Fig. 7 shows the protrusions and grooves similar to those of Fig. 6, but in this embodiment, the stepped groove and the stepped protrusion are rounded to form a gentle curve (actually a curved surface), and the stepped groove has a chin at the entrance, and The middle part of the projection is formed to have a larger width than the neck.

In such a configuration, it is difficult for the two individual mats joined to each other to be spaced apart from each other in a plane, and to move relatively in the thickness direction, and it is difficult for the mat to be disassembled into individual mats by external force when installing the prefabricated mat. The advantage is that it is easy to maintain the overall shape of the mat.

Although not shown here, the step groove and the step protrusion can be formed in various forms. For example, in the cross-sectional view of Fig. 6, the step plane and the side wall of the step groove are at right angles at both sides of the entrance of the step groove, but they are caught at both sides of the entrance. It can be an inverted wedge shape with a jaw, or it can form a V-shape with obtuse angles at both sides of the entrance, and one of the entrances can be formed with a right angle and the other acute or obtuse angle.

In addition, the cross-section of the step groove may be formed in a U-shaped, semicircular or semi-elliptical curve, or may be a double stepped groove in a W-shaped shape. Of course, in these cases, the stepped protrusion has a shape corresponding to the stepped groove.

Figures 8 and 9 show an embodiment of an individual mat 30 having grooves 37 and protrusions 31 in a different shape from the individual mat of the previous embodiment.

In this case, unlike the previous embodiment, in the state of being placed on the floor, a protrusion 31 over the entire side section is provided on the sides corresponding to the upper side and the left side, and the groove 37 over the entire side section is at the side corresponding to the lower side and the right side. ) Is installed. There is a substantial difference in the shape characteristics of the stepped groove 33, the stepped grooved or protruding jaw 35 and the stepped protrusion 39 formed in the protrusion 31 and the protrusion 31. There is no significant difference in that it is possible to easily create an entire prefabricated mat by combining individual mats of the same shape.

However, here, there is a difference in shape in that the protruding jaws 35 are formed not only at both ends of the stepped groove 33 but also in the middle, and a concave portion corresponding to the protruding jaw 35 is formed in the middle of the lengthwise direction of the stepped protrusion 39. .

In the individual mat of the present invention, polyurethane foam is mainly used, but other synthetic resin foams may also be used, and durability, cost, and whether or not harmful substances are included will be factors in consideration of the material. For example, it is desirable to have mechanical strength capable of maintaining durability.

In the previous embodiment, a more rigid and elastic polyurethane coating film covering the polyurethane foam is used on the upper surface of the main body, but if the main body is made of a different material, it can be easily bonded without using a separate adhesive. It is possible to use a stretchable coating film made of synthetic resin made of the same material as the foam. Here, the reason why elasticity is necessary as a coating film is that when the polyurethane foam is deformed, the surface must be able to be deformed together to play the role of a cushion mat, and if it is not deformed, it is difficult to prevent self-damage such as tearing. In this respect, in the case of a coating film, film, or plate bonded to the bottom surface, it is possible that there is no elasticity.

The coating film can be applied not only to the upper surface but also to the lower surface, and it is possible to use a coating film having separate properties for the upper and lower surfaces, and a viscous coating film may be used on the lower surface to increase the adhesive viscosity with the floor.

In addition to the synthetic resin coating film, non-woven fabrics can be combined on the underside of individual mats to enhance buffering and noise prevention.

On the other hand, it is also possible to form a coating film of a water-repellent or waterproof material on the side of the individual mat where grooves and protrusions are formed, depending on the needs of the assembly mat. In this configuration, the coating film prevents the beverage from being absorbed into the body by touching the side surface for a long time in the stepped groove, etc., when the beverage enters the gap of the individual mat assembly connection part, and makes it easy to wipe when removing the beverage.

In addition to water-repellent or waterproof coatings, it is also conceivable to use viscous coatings or adsorption coatings on the side of individual mats. In this case, the bonding force between the individual mats can be further increased, and when small dust particles enter the gap between the assembly joints between the individual mats, the dust particles are adsorbed and attached, so that the dust particles are spread back into the air by children's activities and You can prevent problems that make it worse.

The protrusion thickness or groove depth of the individual mat for assembly may be in the range of 1/4 to 3/4 of the thickness of the individual mat. If the thickness is too small, it is difficult to prevent children's fingers or toes from falling out deeply. If it is too large, the body thickness of the groove portion becomes thin and this portion is liable to be damaged.

In the above, the present invention has been described through limited embodiments, but this has been illustratively described to aid understanding of the present invention, and the present invention is not limited to these specific embodiments. For example, although the embodiment mainly describes an individual mat having a square plane, the present invention may be applied in the same manner to the case of an individual mat having an equilateral triangle or regular octagon as another polygon.

Therefore, those of ordinary skill in the field to which the present invention belongs may implement various changes or application examples based on the present invention, and it is natural that such modifications or application examples belong to the appended claims.
