Description

Prefabricated mat {a prefabricated mat}

The present invention relates to a 'prefabricated mat' that is laid on the floor of a room to prevent interfloor noise and injury to children and the elderly, and prevents the phenomenon of lifting upwards and twisting or relaxing from side to side after different prefabricated mats are assembled. Its main feature is prevention.

Prefabricated mats with a shock-absorbing function are installed on the floor of indoor buildings such as homes, sports facilities, or daycare centers to prevent noise between floors and injury to children and the elderly.

As an example of the prior art of such a prefabricated mat, Korean Patent Registration No. 10-2278312 "A cushion mat for assembly and a prefabricated mat having the same" is disclosed.

In this technology, the mat is made in the shape of a polygonal plate, and a stepped portion made of grooves and protrusions for coupling with adjacent individual mats is installed below the thickness direction on the side of the individual mat for assembly throughout the polygonal side. A stepped groove extending along the side is installed on the upper surface facing upward of the projection, and a stepped projection fitted to the stepped groove is installed on a corresponding surface facing downward of the groove.

When a mat is manufactured and then assembled based on the technology, the height of the upper surface of the mat is jagged and irregular, as shown in FIG. 12 .

As the cause of this phenomenon, it is proposed to prevent up-and-down and left-right flow between different mats by combining a long step groove and a step projection fitted to the step groove. The longer the step groove and the step projection, the more precise the tolerance. It is difficult to have, and gaps can occur, and the long-extended stepped grooves and stepped protrusions have low utilization of the contact area compared to the same area, and the lack of bonding strength between different mats can be cited as the cause.

As an example of the prior art assembly structure of the mat different from the above, as in Korean Patent Publication No. 10-2021-0116985 "Assembly type safety mat", fitting protrusions and fitting grooves are repeatedly formed on the edge of the mat, and other connected It is made in the form of engagement with the mat, although not mentioned in the prior art, typically, the part adjacent to the mat in the fitting protrusion is formed to be narrow in width, and the part away from the mat is made to be wide in width.

As a method of manufacturing a mat, a polyurethane solution is usually put into a mold having a shape to be molded and then a foaming process is performed. , Polyurethane solution is not smoothly supplied to the part where the distance from the mat is far from the fitting protrusion, resulting in molding defects where the flesh is not filled.

In addition, the narrow part adjacent to the mat in the fitting protrusion has a structure with insufficient durability due to the narrow thickness.

Advantages and features of the present invention, and methods for achieving them, will become clear with reference to the embodiments described below in detail in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, and may be implemented in a variety of different forms, and only the present embodiments make the disclosure of the present invention complete, and common knowledge in the art to which the present invention belongs. It is provided to completely inform the person who has the scope of the invention, and the present invention is only defined by the scope of the claims. And like reference numerals designate like elements throughout the specification.

The present invention relates to a 'prefabricated mat' that is laid on the floor of a room to prevent interfloor noise and injury to children and the elderly, and prevents the phenomenon of lifting upwards and twisting or relaxing from side to side after different prefabricated mats are assembled. Its main feature is prevention.

As shown in Figures 1 to 4, the 'prefabricated mat' of the present invention has a body 10 made in the form of a square plate, and a plurality of wings protruding from the lower end of the thickness standard along the edge of the body 10 and formed at set intervals. (20) and a plurality of assembly grooves (30), which are embedded at the lower end of the body (10) along the edge of the body (10) and are formed between the wings (20).

As shown in FIG. 5, one 'fabricated mat' wing part 20 is inserted into and coupled to the other 'fabricated mat' assembly groove 30, so that the combined mats are not scattered left and right.

To this end, both side surfaces of the wing portion 20 are formed in an oblique direction parallel to each other, and both inner side surfaces of the assembly groove 30 extend in an oblique direction at the same angle as both side surfaces of the upper wing portion 20.

When one of the 'prefabricated mat' wing parts 20 and the other 'prefabricated mat' assembly groove 30 are inserted into the above structure, the wing parts 20 and the assembly groove 30 formed in an oblique direction Both sides are in contact with each other to prevent the assembled different prefabricated mats from scattering.

As a means for further reinforcing the bonding force in the structure in which different prefabricated mats are assembled by the wing part 20 and the assembly groove 30 as above, the wing part 20 moves from the edge surface of the body 10 to the body 10 A fitting groove (21a) formed outwardly and dug to a certain depth from the upper side in a rectangular shape; and, the width of the left and right is reduced compared to the fitting groove (21a), and the wings start from one side of the fitting groove (21a) toward the outside of the body (10) A plurality of first T-shaped grooves 21 consisting of; connecting grooves 21b dug to a set depth from the upper side of the portion 20 are formed in plurality at set intervals.

And the assembly groove 30 has a rectangular shape formed on the inner upper surface of the assembly groove 30 and fitted into the fitting groove 21a when the wing portion 20 and the assembly groove 30 of the different assembly mats are coupled. A first projection (31a); and a second projection (31b) formed on one side of the first projection (31a), having a reduced width compared to the first projection (31a), and fitted into the connection groove (21b). In the configuration, a plurality of first T-shaped protrusions 31 are formed at set intervals.

When the above first T-shaped protrusion 31 is coupled to the first T-shaped groove 21, the fitting groove 21a holds the side circumference of the first protrusion 31a, and the second protrusion 31b is connected. By increasing the utilization of area for fixing different prefabricated mats with a structure fitted into the groove 21b, the coupling between the wing portion 20 and the assembly groove 30 can be made more robust.

The prefabricated mat of the present invention has a foaming process after the polyurethane solution is put into a mold having a shape to be molded.

In this molding process, the first T-shaped protrusion 31 requires that the polyurethane solution be supplied to the first protrusion 31a through the second protrusion 31b, which has a narrower width than the first protrusion 31a. If the solution is not smoothly supplied to the first projection 31a through the second projection 31b, a molding defect in which the first projection 31a is not completely filled with flesh may occur.

In order to prevent this, a first reinforcing rib 32 is formed at the top of the first T-shaped protrusion 31 to have a certain thickness and to connect the tops of the different first T-shaped protrusions 31 so that they are integrated. Molding defects of the first projections 31a can be prevented by allowing the polyurethane solution to smoothly flow into the first projections 31a through the first reinforcement teeth 32 and the second projections 31b.

In addition, the first reinforcing rib 32 connects the upper ends of the first protrusion 31a and the second protrusion 31b to prevent the second protrusion 31b, which is narrower than the first protrusion 31a, from being damaged. Do it.

At the upper end of the wing portion 20, a third protrusion 22a formed between the connecting groove 21b cut to a set depth; and formed between the fitting groove 21a by the first T-shaped groove 21, A second T-shaped protrusion 22 consisting of a fourth protrusion 22b having a narrower left and right width than that of the three protrusions 22a is formed.

Like the third protrusion 22a and the first protrusion 31a during molding of the prefabricated mat, if the polyurethane solution does not flow smoothly through the fourth protrusion 22b, which has a narrower left and right width than the third protrusion 22a, the weight is not filled. Molding defects may occur, and in order to prevent this, the second reinforcement is located at the bottom of the second T-shaped protrusion 22, has a certain thickness, and connects the lower ends of the different second T-shaped protrusions 22 to make them integral. The ribs 23 are formed so that the polyurethane solution smoothly flows into the third protrusion 22a through the second reinforcing rib 23 and the fourth protrusion 22b, thereby preventing molding defects of the third protrusion 22a. be able to prevent

In addition, the second reinforcement rib 23 connects the lower ends of the third protrusion 22a and the fourth protrusion 22b to prevent the fourth protrusion 22b, which is narrower than the third protrusion 22a, from being damaged. Do it.

It is preferable that two or more pairs of wing parts 20 and assembly grooves 30 having the above structure are formed for each edge of one side of the body 10. Due to this, molding errors may occur in the height of the wings 20 and the depth of the assembly groove 30, and these errors are irregular so that the height of the upper surface of the body 10 is jagged when assembling different prefabricated mats, as shown in FIG. can make it

If only one pair of wing parts 20 and assembly grooves 30 are formed for each one edge of the body 10, as described above, half of the height of the upper surface of one edge of the body 10 when assembling different prefabricated mats can protrude upward and the rest of the sections can have an irregular shape going downward.

In order to compensate for this, when two or more pairs of wing parts 20 and assembly grooves 30 are formed for each edge of one side of the body 10, the part to protrude upward from the upper surface of the body 10 and the part to go down are mutually By complementing each other, it is possible to reduce the height deviation of the upper surface of the body 10.

In addition, the boundary where the upper end of the wing 20 and the side surface of the body 10 come into contact does not form a perfect right angle as shown in FIG. Round meat (R) may be formed. When such a round meat (R) is formed, when assembling different prefabricated mats, the first reinforcing meat 32 of the other prefabricated mats on which the wings 20 are raised are round meat ( R) can be pushed upwards.

Therefore, in the present invention, in order to prevent the above problem, as shown in FIG. 7, by forming a groove 24 of a certain depth along the boundary where the upper end of the wing portion 20 and the side surface of the body 10 come into contact, the round meat ( R) is prevented from being formed to prevent lifting when assembling different prefabricated mats.

In addition, chamfers 25 are formed by cutting out the edges at both corners of the wing 20 in contact with the side surfaces of the body 10, which, as shown in FIG. 6, when different prefabricated mats are assembled, the wing 20 ) to prevent interference between the edges of the wing portion 20, so that left and right twisting of the prefabricated mat due to edge interference does not occur.

On the bottom surface of the body 10, a plurality of wavy grooves 40 with a set depth are formed at regular intervals to increase the frictional force between the building floor and the bottom surface of the body 10, so that the prefabricated mat does not slide off the building floor. reduces that

In addition, ventilation grooves cut to a set depth so as to surround the edges of the plurality of wavy grooves 40 on the bottom surface of the body 10 and the wing 20 in all directions and pass through the side surfaces of the wing 20 and the assembly groove 30. (50) is formed, so that moisture that may be formed under the prefabricated mat is dried by the air flowing into the wavy grooves 40 and the ventilation grooves 50, preventing mold and bacteria from propagating under the prefabricated mat made to reduce

A picture or pattern set by the user can be displayed on the upper surface of the prefabricated mat. As shown in FIG. A film 60 of may be attached.

The characteristics of TPU include excellent flexibility, tensile strength, durability and abrasion resistance, and excellent printing properties. there is.

In addition, the film 60 made of TPU has waterproofness and prevents water or moisture on the prefabricated mat from being absorbed into the body 10, thereby preventing the body 10 from being contaminated.

In another embodiment, when assembling different prefabricated mats as shown in FIG. 11, it is possible to form a beautiful appearance by trimming the angular portion of the edge of the body 10 so that the wings do not protrude from the outer edge portion.

To this end, in the structure in which different prefabricated mats are assembled, the body 10 of the prefabricated mat located at the corner forms an inclined surface 11 whose height decreases from the inside to the outside of the two sides of the body 10, and the inclined surface 11 The wing portion 20 and the assembly groove 30 are not formed on the edge of the body 10 formed thereon.

In addition, in a structure in which different prefabricated mats are assembled, the body 10 of the prefabricated mat located between the corners forms an inclined surface 11 in which one side decreases in height from the inside to the outside of the body 10, and the inclined surface 11 The wing portion 20 and the assembly groove 30 are not formed on the edge of the body 10 formed thereon.

In addition, the edge 12 of the body 10 adjacent to the inclined surface 11 may have a thickness of 2 to 5 mm in a form perpendicular to the bottom surface of the body 10.

If the thickness of the upper rim 12 is formed to be less than 2 mm, a defect in that the rim 12 is rolled up or down due to lack of rigidity occurs, so the thickness of the rim 12 is preferably set to at least 2 mm or more. do.
