The same reference numerals refer to the same elements throughout the specification.

Hereinafter, a sofa 100 according to an embodiment of the present invention will be described with reference to the drawings.

1 and 4, a sofa 100 according to an embodiment of the present invention includes a plate-shaped seating body 40 including a wood layer 10, a heating layer 20, and a unit block layer 30. .

The sofa 100 may further include a seating body frame F1 surrounding the rim of the plate-shaped seating body 40 stacked in multiple layers, as well as the plate-shaped seating body 40 and the seating body frame F1. It may include a support frame (F2) separated from the ground and connected to both ends of the seating body frame (F1).

The plate-shaped seating body 40 is a multi-layered structure and is a part of the sofa 100 in which the user can directly sit, and the sofa 100 according to the present invention is a unit formed by combining a plurality of unit blocks 31 By including the block layer 30, it has excellent seating and warmth transmission efficiency.

Specifically, the plate-shaped seating body 40 includes a plate-shaped wooden layer 10. The plate-shaped wood layer 10 may form a structural frame supporting the plate-shaped seating body 40. The plate-shaped wood layer 10 may include solid wood such as plywood and cypress, but is not limited thereto, and it will be said to include a range that can be easily selected by a person skilled in the art.

A heating layer 20 that generates heat by external power may be disposed on the plate-shaped wood layer 10.

The heating layer 20 may be heated with hot water by external power or the wire may be heated, and the warmth generated in the heating layer 20 passes through the unit block layer 30 disposed on the heating layer 20 to be seated in a plate shape. It can be delivered to the user seated in the body 40. A detailed description of the heating layer 20 will be described later.

As described above, the unit block layer 30 is disposed on the heating layer 20, and the unit block layer 30 may be a layer in which a plurality of hexagonal unit blocks 31 are interwoven to form one surface.

Specifically, the unit block layer 30 of the sofa 100 and the unit block 31 constituting the unit block layer 30 according to an exemplary embodiment of the present invention will be described with reference to FIGS. 1 to 3.

The unit block 31 may include clay powder. In addition, the unit block 31 may further include charcoal, rosin and wood powder. The unit block 31 has a function of controlling humidity and maintaining temperature by including clay powder, and the far-infrared rays are radiated by the warmth generated in the heating layer 20 to promote the metabolism of the seated user, thereby benefiting health. I can.

Referring back to FIGS. 2 and 3, the unit block 31 according to the embodiment of the present invention is a dry unit block, and a plurality of pores may be disposed therein.

In the present specification, the dry unit block is a concept opposite to the conventional forming by pressing a plate-top layer containing stones and soil at high pressure, and is formed by drying a unit block paste (not shown) without high pressure pressing. .

Specifically, by preparing a unit block paste (not shown) containing at least one of clay powder, charcoal, rosin and wood powder, and drying the unit block paste (not shown) to correspond to the shape of the unit block 31 The dry unit block 31 can be formed.

Referring back to the enlarged portion shown in FIG. 3, the unit block 31 according to the embodiment of the present invention is a dry unit block 31, not high pressure compression, so a number of moisture and solvents are removed during the drying process. It may be a porous unit block 31 in which micropores P are formed.

The sofa 100 according to an exemplary embodiment of the present invention includes a dry unit block 31 in which pores P are formed instead of high pressure compression, thereby improving cushioning characteristics, thereby providing an excellent seating feel to a user.

Specifically, since a plurality of pores P included in the unit block 31 are formed in the unit block 31 within a range that does not impair the durability of the unit block 31, the pores P are formed in the unit block 31 ) By increasing the elasticity, the cushioning characteristics are improved, and as a result, an excellent seating feeling can be realized.

The plurality of unit blocks 31 constitute the unit block layer 30 so that a direct impact or weight is applied to a portion where the user is directly seated. Accordingly, the unit block 31 according to the embodiment of the present invention divides the structure of the unit block 31 and controls the configurations that can enhance durability for each of the divided structures. Can be implemented.

First, the shape (border) of the unit block 31 forming the unit block layer 30 may be hexagonal. By forming a hexagonal shape of the unit block 31, it is possible to improve structural stability by preventing the impact applied to the unit block 31 from being concentrated on a part. However, the fact that the unit block 31 is a hexagon does not mean that each of the plurality of unit blocks 31 is all hexagonal, and the unit block 31 located at the rim of the sofa 100 is inevitably a part of the hexagonal shape. It will be said that it includes even those formed by.

In addition, the unit block 31 may be sequentially divided from an upper surface to a thickness direction into a surface layer 31a, an intermediate layer 31b, and a bottom layer 31c.

The surface layer 31a is a part where the user is seated and may physically contact the user, and the surface layer 31a may include a surface oil coating layer 31a ′ formed by impregnating the upper surface of the unit block 31.

The surface oil coating layer 31a' may be impregnated at a predetermined depth from the upper surface of the unit block 31 to the inside. The surface oil coating layer 31a' coats the upper surface of the surface layer 31a to a certain thickness, so that even if a direct physical contact occurs due to a user's seating, it is possible to prevent the surface layer 31a from being etched and broken. It can effectively prevent the occurrence of surface cracks due to impact or the like.

Furthermore, contaminants that may occur during the user's use may be prevented from seeping into the unit block 31 and being contaminated.

The intermediate layer 31b may include at least one mesh-like fibrous fabric 31b1. The mesh-type fiber fabric 31b1 may be disposed over the entire area of the cross-section of the intermediate layer 31b, and a plurality of mesh-type fiber fabrics 31b1 may be spaced apart from each other and disposed horizontally.

The mesh-type fiber fabric 31b1 further improves the durability of the unit block 31 to effectively prevent the unit block 31 from being broken or an internal crack from occurring due to an impact applied from the outside.

The mesh-like fiber fabric 31b1 may include carbon fibers or the like. The mesh-type fiber fabric 31b1 including carbon fibers is light and has little reactivity, so there is little fear of corrosion or contamination, and has excellent elasticity, which helps improve durability. In addition, heat transfer efficiency may be improved due to excellent thermal conductivity.

Furthermore, the intermediate layer 31b may further include a plurality of dispersed fiber strands 31b2.

Some of the plurality of fiber strands 31b2 may be located inside the surface layer 31a, and another part may be located inside the bottom layer 31c.

Since some of the plurality of fiber strands 31b2 disposed on the intermediate layer 31b are disposed on the surface layer 31a and the bottom layer 31c, the durability of the unit block 31 may be further improved.

That is, some of the fiber strands 31b2 disposed on the surface layer 31a and the bottom layer 31c are structured to firmly support the surface layer 31a, the intermediate layer 31b, and the bottom layer 31c. Even if this occurs, it is possible to prevent the propagation of cracks and to effectively endure an impact in the transverse direction, thereby improving durability.

In addition, the fiber strands 31b2 may include carbon fiber strands. By including the carbon fiber strands, the durability can be further improved, and the heat transfer efficiency can be further increased.

In the unit block 31, edges of the surface layer 31a and the intermediate layer 31b may be hexagonal, and three-dimensionally, may have a hexagonal column shape. On the other hand, the bottom layer 31c, which will be described later, may have a dome shape protruding toward the lower layer.

Accordingly, the plurality of unit blocks 31 forming the unit block layer 30 may form one surface by interlocking the surface layers 31a and the intermediate layers 31b of the unit blocks 31 with each other.

The intermediate layer 31b may further include a side oil coating layer 31b' formed by impregnating the side surface. The side oil coating layer 31b' may be formed by being impregnated with a certain thickness from the side of the intermediate layer 31b to the inside, and the side oil coating layer 31b' is prevented from impacts in one direction occurring during the use of the sofa 100. As a result, it is possible to effectively prevent an etching phenomenon that may occur when the side surfaces that are aligned with each other rub against each other.

The side oil coating layer 31b' may be formed not only on the intermediate layer 31b, but also on the side surfaces of the surface layer 31a, and may be connected to the surface oil coating layer 31a'.

Subsequently, as described above, the bottom layer 31c may have a dome shape protruding downward, and may have a hemispherical shape having a diameter smaller than that of the surface layer 31a and the intermediate layer 31b.

Unlike the surface layer 31a and the intermediate layer 31b, the bottom layer 31c is dome-shaped, and the force is applied to the unit block 31 in any direction, such as up, down, left, and right, which can be caused by movement after the user sits on the sofa 100. Even if applied, it is possible to effectively reduce the concentration of stress, and as a result, it is possible to prevent wear and improve durability.

Specifically, the unit block 31 is positioned on the heating layer 20, and the bottom layer 31c is in physical contact with the heating layer 20. Therefore, a force is applied in the direction of the ground by the user's seating, and a force may be applied to the surface of the bottom layer 31c in contact with the surface of the heating layer 20, but the stress is concentrated in a dome shape in the bottom layer 31c. Since it does not include corners, etc., wear and impact caused by physical contact can be minimized.

In the present specification, the dome shape does not mean only a hemispherical shape, and it should be understood that it includes a shape that is a gentle protruding portion even if the longitudinal length varies according to the cross-sectional direction.

A plurality of unit blocks 31 including a dome-shaped portion are disposed on the heating layer 20, and the heating layer 20 is formed by forming a plurality of concave grooves 21 corresponding to the dome shape of the bottom layer 31c. A plurality of unit blocks 31 may be stably disposed on the heating layer 20.

1 to 5, the bottom layer 31c of the unit block 31 may be seated and fixed in the concave groove 21 of the heating layer 20. Specifically, the unit blocks 31 in which the bottom layer 31c is disposed in the concave groove 21 are interwoven with the adjacent unit blocks 31, and thus may be firmly fixed in the left and right directions to be disposed. On the other hand, in the unit block layer 30, a plurality of unit blocks 31 are firmly fixed in the left and right directions, but are not fixed in the vertical direction, and each of the unit blocks 31 can be attached and detached vertically. .

That is, even if some of the plurality of unit blocks 31 are broken or cracked while the sofa 100 is being used, only the unit block 31 in which the damage has occurred needs to be lifted up and replaced. And easy to repair.

In addition, the unit block layer 30 is composed of a plurality of unit blocks 31 adjacent to each other, and since it is an independent configuration, even if a crack or the like occurs in one unit block 31, it is cracked by the adjacent unit block 31. It is possible to structurally block the spread of damage due to propagation, making it easy to repair and repair.

The heating layer 20 of the sofa 100 according to the exemplary embodiment of the present invention may be heated by external power. Specifically, the heating layer 20 may include a plurality of heating lines 22, and at least a portion of the plurality of heating lines 22 helically surround the interface of the concave grooves 21 formed in the heating layer 20. Can be placed.

The heating line 22 may include an electric resistance line or a hot water line, and when external power is applied, heat may occur in the electric resistance line itself, or heat may be generated by heating water to make hot water.

Since the heating line 22 is arranged to entirely surround the interface of the concave groove portion 21 in which the dome-shaped bottom layer 31c is disposed, the area in contact with the bottom layer 31c is large, so that a large amount of heat is effectively transmitted to the unit block 31 ) Can be applied. Further, the user is directly seated on the unit block 31 without a separate intermediate member, and the mesh-like fiber fabric 31b1 and the fiber strands 31b2 included in the unit block 31 are carbon fibers having good thermal conductivity. By including it, you can effectively deliver warmth to the user.

In addition, the bottom layer 31c has a dome shape, and since stress concentration is minimized, the possibility that the heating wire 22 is damaged due to an external impact may be reduced.
