For example, the cover part 500 may be made of natural fibers such as a merino wool knit fabric that can be pulled out of wool.

Meanwhile, various layers may be provided inside the cover part 500 to provide comfort and comfort when a user lies down or sits down.

For example, the mattress 1000 includes an upper cushion layer 350 on which the user's body is seated, and a memory layer that is provided under the upper cushion layer 350 to restore shape when a load by the user disappears. 340, a deformation absorbing layer 320 provided under the memory layer 340 and capable of absorbing deformation due to a user's load, and an intermediate cushion layer 310 provided below the deformation absorbing layer 320 ), and a pocket spring part 200 that is located under the intermediate cushion layer 310 and serves as a main spring part by providing elastic force, and a lower cushion layer 100 located under the pocket spring part 200 It may include.

The upper cushion layer 350 is positioned on the inner side of the mattress 1000 to provide elasticity when a user or a user lies down or sits.

In this case, the upper cushion layer 350 may be positioned at the top to form an uppermost layer in contact with the user's human body.

The upper cushion layer 350 includes various cushioning materials such as fabric, nonwoven fabric, filler, foaming agent (eg, sponge, etc.), along with various cushion layers to be described later, and has a certain thickness to secure a buffer space. Is composed.

Here, these various buffering materials are natural materials or synthetic materials, which are mostly highly flammable materials, and may serve to further expand the flame when the flame is propagated. Accordingly, the flame propagation prevention layer 370 is required, as described later, which will be described in detail later.

In addition, an additional layer may be further included on the upper cushion layer 350 to provide a user with a sense of comfort.

For example, a padding layer 360 may be further provided on the upper cushion layer 350. The padding layer 360 may be made of a material having a delicate and soft texture, and may be made of, for example, cashmere, which is made of a natural material to provide a light feeling of use.

On the other hand, the mattress 1000 according to the present invention is a flame that prevents flames that may be generated in the cover part 500 of the mattress from spreading to various layers inside the cover part 500 of the mattress 1000 An anti-propagation layer 370 may be further provided.

The flame propagation prevention layer 370 may be provided on the upper cushion layer 350, and more precisely, may be provided on the padding layer 360. Accordingly, it is possible to prevent flames that may occur in the cover part 500 of the mattress 1000 from spreading to various layers inside the cover part 500.

The flame propagation prevention layer 370 is configured to have high flame retardancy or high nonflammability or high flame retardancy.

For example, the flame propagation prevention layer 370 may be formed by adding an additive flame retardant such as a halogen-based flame retardant, an inorganic flame retardant, or a phosphorus-based flame retardant to the material. In addition, the flame propagation prevention layer 370 may be formed by flame-retardant yarn, and in this case, the flame-retardant yarn may be produced by chemically copolymerizing a flame-retardant material in the yarn by polymerization. Further, the flame propagation prevention layer 370 may be manufactured by a post-processing method such as a method of heat treatment or a method of coating a material after drying by immersing it in a flame retardant resin.

Accordingly, the present invention includes a flame propagation prevention layer 370 (or a flame retardant layer) inside the mattress 1000, so that when a fire occurs directly in the mattress 1000 or when a bedroom fire occurs, the cover part 500 of the mattress 1000 ) To burn only the outer cover, and the flame of the cover part 500 can be prevented from propagating to various combustible layer structures located inside the mattress cover part 500.

That is, the present invention can prevent the flame of the mattress cover part 500 from spreading to the inside.

In addition, the present invention includes a flame propagation prevention layer 370 (or flame retardant layer) in the mattress 1000, so that the flame generated inside the mattress 1000 when an internal fire occurs in a structure having a heating element inside the mattress 1000 It is possible to prevent propagation to the outside of the mattress 1000.

And, the present invention by disposing the flame propagation prevention layer 370 (or flame retardant layer) as close to the cover part 500 as much as possible, preventing damage to the aesthetic feeling of the whole mattress 1000 due to the flame propagation prevention layer 370 At the same time, the flame retardant material or by-product of the flame retardant material included in the flame propagation prevention layer 370 is exposed to the outside of the mattress 1000 to minimize contact with the user's human body.

That is, in the case of a flame retardant material, when exposed to the human body of a user, especially an infant or child, since it has harmful effects such as damage to the sympathetic nerve, the present invention has a fire spread prevention function, and at the same time, the user due to the flame retardant material having such harmfulness It can minimize damage to the human body.

4 is a perspective view showing the flame propagation prevention layer 370 exploded.

Referring to FIG. 4, the flame propagation prevention layer 370 is configured to include a flame retardant layer and a sealing portion 371 surrounding the flame retardant layer in a sealing manner.

The flame retardant layer has a planar structure corresponding to the upper surface of the mattress 1000 and is made of a flame retardant material.

In addition, the sealing part 371 is configured to seal the flame retardant layer, and the flame retardant material included in the flame retardant layer or a by-product of the flame retardant material (for example, peeling particles, volatile organic compounds (VOC), etc.) It is possible to prevent the propagation prevention layer 370 from being exposed to the outside.

The sealing part 371 is, for example, as shown in FIG. 4, the upper sheet 371a, the lower sheet 371b, and the upper sheet 371a and the lower sheet 371b are coupled in an airtight manner. It may be configured to include a sealing connection (371c).

Accordingly, the present invention can prevent the flame-retardant material of the flame-retardant layer or by-products of the flame-retardant material from being exposed to the outside of the flame propagation prevention layer 370 or the mattress 1000.

In addition, the flame retardant layer may include a flame retardant fiber sheet 372.

The flame-retardant fiber sheet 372 is configured to include at least one of a fabric woven with flame-retardant fibers and a non-woven fabric made of flame-retardant fibers.

Here, the flame-retardant fiber is composed of, for example, polyacrylic, modacrylic, polyvinyl chloride, or the like, or by mixing an additive flame retardant such as a halogen-based flame retardant, an inorganic flame retardant, or a phosphorus-based flame retardant to the polyester in the fiber manufacturing step. It may be composed of fibers or flame-retardant polynosic.

Accordingly, the present invention can minimize the thickness of the flame propagation prevention layer 370 by configuring the flame retardant layer of the flame-retardant fiber sheet 372.

That is, the mattress cover part 500 according to the present invention can secure flame retardancy while minimizing the thickness of the flame propagation prevention layer 370.

As a result, the present invention can prevent damage to the human body of a user (especially, infants and toddlers) due to a flame-retardant material having a fire spread prevention function and at the same time having a human body hazard at the same time (ie, before a fire occurs).

Meanwhile, in general, when looking at the location of the fire occurrence of the mattress 1000, it mainly occurs on the upper surface (ie, the human body contact surface) of the mattress cover part 500.

Therefore, the present invention is manufactured by providing the flame propagation prevention layer 370 only on the upper inner surface of the mattress cover part 500, thereby effectively implementing a fire spread prevention function and minimizing the use of relatively expensive flame retardant materials. Unit cost can be reduced.

In the case of FIGS. 2 and 3, the flame propagation prevention layer 370 is shown to be formed on the padding layer 360, but is not limited thereto. For example, although not shown in the drawings, the flame propagation prevention layer 370 may be provided under the mattress 1000 or at a side surface of the mattress 1000.

For this reason, the present invention is provided to protect the flame propagation prevention layer 370 to the side and bottom surface of the mattress 100 when necessary (for example, when the flame propagates from the bedroom floor to the mattress 1000), or By providing so as to surround the entire circumference of the structure 100, it is possible to more reliably prevent flames from spreading between the mattress cover 200 and the inside of the mattress even in various fire occurrence situations.

Meanwhile, referring to FIGS. 1 to 3, an upper finishing material 410 may be further provided on the flame propagation preventing layer 370. In addition, a side finishing material 430 may be provided on the side of the mattress 1000. Furthermore, a lower finishing material 420 may be further provided under the lower cushion layer 100.

Meanwhile, a memory layer 340 may be further provided under the upper cushion layer 350. The memory layer 340 may be composed of, for example, a memory layer capable of deforming according to the load when a load is applied by a user and restoring the original shape when the load by the user disappears. have.

When the user lies down or sits down, the memory layer 340 is deformed in response to the user's load so that the user can feel comfortable and comfortable. In addition, when the user deviates from the mattress 1000 and no load by the user is applied, the memory layer 340 is restored to its original shape so that the appearance of the mattress 1000 is flat and the appearance of the mattress 1000 can be maintained. .

The memory layer 340 may be configured to have a shape including a plurality of convex portions or a convex shape as shown in the drawing. In this way, the restoring force to restore to the original shape can act more reliably by the configuration having a plurality of convex portions.

The memory layer 340 may be made of, for example, a new material foam providing excellent elasticity and excellent resilience. In this case, the density of the memory layer 340 may have a density of approximately 25 kg/m 3 to 35 kg/m 3.

Meanwhile, a deformation absorbing layer 320 capable of absorbing deformation due to a user's load may be further provided under the memory layer 340.

When the user lies down or sits on the mattress 1000, if the deformation due to the user's load is transmitted to the lowest layer of the mattress 1000, the elastic force of the mattress 1000 may not be properly transmitted to the user, and the user may not feel comfortable. .

Accordingly, the mattress 1000 may further include a deformation absorbing layer 320 to provide excellent durability while maximally absorbing the deformation caused by the load when a load by the user acts.

5 is a cross-sectional view of the mattress 1000.

Referring to FIG. 5, the deformation absorbing layer 320 of the mattress 1000 may be positioned above the pocket spring part 200. In this case, an intermediate cushion layer 310 may be further provided between the strain absorption layer 320 and the pocket spring part 200. The intermediate cushion layer 310 prevents the deformation absorbing layer 320 from directly contacting the upper portion of the pocket spring 200 so that deformation absorption due to a user's load can be made more smoothly.

The strain absorption layer 320 may be processed into a new material having excellent durability and resilience. For example, the strain absorption layer 320 may have a density of about 55 kg/m 3 to 65 kg/m 3.

The deformation absorbing layer 320 may include a deformation absorbing part 324 that absorbs deformation when deformation occurs due to a user's load.

The deformation absorbing unit 324 absorbs the deformation when deformation occurs due to a user's load, thereby reducing the amount of the deformation being transmitted to the lower layer.

For example, the strain absorbing portion 324 may be formed of a plurality of slits 321 cut toward the upper surface of the strain absorbing layer 320 and a groove portion 322 connected to the slits 321.

The slit 321 may be formed on the upper surface of the strain absorbing layer 320, and a groove 322 connected to the slit 321 may be formed inside the slit 321.

Accordingly, when a user's load is applied, the slit 321 is opened as the groove portion 322 is pressed, so that the deformation can be absorbed as much as possible.

On the other hand, assuming that the user lies on the mattress 1000 as shown in FIG. 6, the regions in which the load is most applied by the user's human body may roughly correspond to the user's head and hips.

Accordingly, the deformation absorbing unit 324 may be disposed in a region corresponding to the user's head and hips when the user lies on the mattress 1000 as shown in the drawing.

However, the arrangement of the deformation absorbing unit 324 is merely described as an example, and may be appropriately modified and provided. For example, the mattress 1000 may be appropriately deformed and provided according to the area and thickness of the mattress 1000 or the gender, age, or injection location of a user who uses the mattress 1000.

Meanwhile, referring to FIGS. 2 and 3, an antibacterial layer 330 may be further provided between the strain absorbing layer 320 and the memory layer 340.

When the user sleeps using the mattress 1000, sweat and secretions may be discharged from the user's body. In this case, microorganisms and the like may propagate in the mattress 1000 due to such secretions. This does not provide a comfortable environment to a user who uses the mattress 1000 and may cause discomfort and various diseases.

Therefore, as described above, it is possible to provide insect-repellent and antibacterial functions to the cover part 500, and an antibacterial layer 330 is also disposed in the middle of the mattress 1000 to provide insect-repellent and antibacterial functions to provide hygienic sleep. You can provide an environment.

The antibacterial layer 330 may provide elasticity with an excellent antibacterial effect. In this case, the antibacterial layer 330 may have a density of approximately 55 kg/m 3 to 65 kg/m 3.

A pocket spring part 200 providing a main elastic force may be disposed under the above-described intermediate cushion layer 310.

On the other hand, including the flame propagation prevention layer 370 described above, the upper finishing material 410, the padding layer 360, the upper cushion layer 350, the memory layer 340, the antibacterial layer 330, the deformation absorption layer 320, At least one of the middle cushion layer 310, the lower cushion layer 100, the lower finish material 420, and the side finish material 430 is configured to have high flame retardancy, high non-flammability, or high flame retardancy Can be.

In this way, in addition to the flame propagation prevention layer 370, various layers and/or finishing materials constituting the mattress 1000 are configured to have high flame retardancy, high non-flammability, or high flame retardancy, and the mattress ( It is possible to more effectively prevent flames that may occur in the cover part 500 of 1000) from propagating to various layers inside the cover part 500.

At this time, the upper finishing material 410, the padding layer 360, the upper cushion layer 350, the memory layer 340, the antibacterial layer 330, the strain absorbing layer 320, the intermediate cushion layer 310, the lower cushion layer (100), at least one of the lower finish material 420 and the side finish material 430 may be manufactured by at least one of the above-described method of adding an additive flame retardant, a method of using flame-retardant yarn, or a post-processing method.

For example, the upper finishing material 410, the padding layer 360, the antibacterial layer 330, the side finishing material 430, etc. may be added by the method of adding the aforementioned additive flame retardant, the method of using flame-retardant yarn, or the post-processing method. Can be made.

In addition, the upper cushion layer 350, the memory layer 340, the deformation absorbing layer 320, the intermediate cushion layer 310, the lower cushion layer 100, the lower finishing material 420 is a method of adding the aforementioned additive flame retardant. Or it may be produced by a method using flame retardant yarn.

7 is a perspective view of the pocket spring part 200 and FIG. 8 is an exploded perspective view of the pocket spring part 200.

7 and 8, the pocket spring part 200 includes a pocket spring 230 disposed in a plurality of rows, and an upper wire frame disposed at the upper and lower edges of the pocket spring 230, respectively. 210 and a lower wire frame 220 may be provided.

Each of the plurality of pocket springs 230 may include a pocket 250 in which a plurality of coil springs 240 are accommodated.

The pocket 250 may be formed of a material such as a nonwoven fabric, and may be selected as a suitable material capable of accommodating the coil spring 240.

The coil spring 240 may have a shape in which a spring core having a predetermined thickness is twisted from a lower portion toward an upper portion for a predetermined number of times.

Meanwhile, the pocket spring 230 may include an upper wire frame 210 and a lower wire frame 220 to fix the shape at the edge thereof.

The upper and lower ends of the pocket springs 230 disposed at the edges of the pocket springs 200 are connected to the upper wire frame 210 and the lower wire frame 220, respectively, so that the overall shape of the pocket spring part 200 Can be maintained.

In this case, in the case of a mattress having a pocket spring in the related art, a technique of fixing the pocket spring using a generally circular wire is employed to fix the pocket spring.

In the case of such a conventional structure, the stiffness of the circular wire was relatively weak, and it was difficult to maintain the overall shape of the pocket spring portion. In addition, in the case of fixing the pocket spring to the wire using a hook or the like, there is a problem in that the position of the hook cannot be fixed due to the shape of the circular wire. If the position of the locking chain is not fixed, the locking chain moves along the wire, so that the pocket spring is not reliably fixed.

In order to solve this problem, in the case of the mattress 1000 according to the present invention, the upper wire frame 210 and the lower wire frame 220 may be provided in a form having at least one flat portion 212.

For example, the upper wire frame 210 and the lower wire frame 220 may be provided in the form of a flat wire, or may have a flat portion and have a bent'A' shape.

When the upper wire frame 210 and the lower wire frame 220 have the above-described structure, relatively excellent rigidity can be provided compared to the conventional one. Thereby, the overall shape of the pocket spring part 200 can be stably maintained.

In addition, when the upper wire frame 210 and the lower wire frame 220 are disposed, the above-described flat portion 212 may be disposed to face the top or bottom.

When the flat portion 212 is disposed at the edge of the pocket spring 200 toward the top or bottom, the top and bottom shapes of the pocket spring 200 are flattened by a flat shape. You can keep it. In this case, a more comfortable environment may be provided when the user lies down or sits on the mattress 1000.

Meanwhile, in the upper wire frame 210 and the lower wire frame 220, a locking chain 214 for fixing the pocket spring 230 is inserted to form a position fixing portion 216 at a predetermined interval. Can be.

The locking chain 214 serves to fix the pocket spring 230 to the upper wire frame 210 and the lower wire frame 220.

The locking chain 214 is shown in a circular shape in the drawing, but is not limited thereto, and any shape capable of fixing the pocket spring 230 to the wire may be used.

In this case, if the position of the locking chain 214 is not fixed, a fixing force for fixing the pocket spring 230 to the upper wire frame 210 and the lower wire frame 220 may be weakened.

Accordingly, in the present embodiment, a position fixing part 216 capable of fixing the position of the locking chain 214 may be formed on the upper wire frame 210 and the lower wire frame 220.

The locking chain 214 may be inserted into the position fixing part 216 and configured to pull the pocket spring 230.

For example, in the case of fixing the pocket spring 230 by the locking chain 214, the locking chain 214 is inserted into the position fixing part 216 and the end of the locking chain 214 is It can be fixed by connecting through the pocket spring 230.

Meanwhile, the position fixing part 216 is illustrated in the shape of a concave portion formed in the upper wire frame 210 and the lower wire frame 220, but is not limited thereto. For example, the position fixing part 216 may be provided in the shape of a hole formed in the upper wire frame 210 and the lower wire frame 220.

Meanwhile, a lower cushion layer 100 may be disposed under the pocket spring part 200 between the frame part 10 and the frame part 10.

The lower cushion layer 100 is disposed on the upper surface of the frame unit 10, and the pocket spring unit 200 described above is disposed on the lower cushion layer 100.

The lower cushion layer 100 serves to provide an elastic force while properly supporting the pocket spring part 200.

The lower cushion layer 100 may have adequate durability and repulsion so that the pocket spring portion 200 does not bounce against the frame portion 10 (non-flip).

If the lower cushion layer 100 is omitted and the pocket spring part 200 is directly seated on the upper surface of the frame part 10, the frame part ( The pocket spring part 200 may splash against the upper surface of 10). This may cause discomfort to the user when the user lies down or sits down, and does not provide a comfortable environment.
