Description

5-layer foam mattress {Foam mattress comprising five layers}

The present invention relates to a mattress, and more specifically, by providing a foam mattress with five layers of different physical properties specially designed and combined, that is, a five-layer foam mattress, which can provide comfort no matter what posture the user takes, and at the same time maintains structural stability. This is about a safe foam mattress.

In order to provide a more comfortable and comfortable feeling to the user of the mattress, the use of memory foam is increasing so that the mattress can be adjusted to fit the user's shape and be restored. A mattress containing memory foam is hereinafter referred to as a foam mattress.

In general, foam mattresses can be divided into latex, which is made from rubber materials, and memory foam, which is made from chemical materials.

In the case of latex, it supports the user's body with its own elasticity, but it is weak to heat and light and has low breathability, making it unsuitable for use as a mattress.

Memory foam is a specially processed form of foam that has higher elasticity than urethane. It has viscoelasticity by adding viscosity to elasticity, and has the characteristic of recovering after being pressed, but slowly.

On the other hand, when a user lies down on a foam mattress made of one layer, various problems may occur, such as being too hard or excessively compressed, depending on the physical properties of the foam mattress. Accordingly, there is a trend toward using foam mattresses made of multiple layers.

Recently, as technology has been developed to naturally adjust the density or hardness of viscoelastic memory foam, it has become possible to variously combine the density, hardness, and thickness of each layer in a foam mattress made of multiple layers. The user's level of comfort will vary depending on the combination.

1st In the example according to foam mattress

Figure 1 shows the inner fabric layer 10, the top fabric layer 11, the zipper portion 12, and the bottom fabric layer 13, which are the outer skin of the comforter portion 100 of the foam mattress according to the first embodiment of the present invention. shows.

The inner fabric layer 10 is located at the top, bottom, and sides and surrounds the outside of the comfort portion 100, and may preferably be a knit material containing spandex polyester.

In another embodiment, a knit material including spandex polyester and a part of jacquard material without spandex may be used for the inner fabric layer 10.

The upper plate fabric layer 11 is located on the upper and upper side of the side portion, and the lower plate fabric layer 13 is located on the lower and lower side of the side portion.

The upper plate fabric layer 11 and the lower plate fabric layer 13 are made of different materials because their functions are different.

Since the top fabric single layer 11 is a part that the user's body directly touches when lying down, it is desirable to secure spandex. Therefore, it is preferable that it is a knit material containing polyester.

The lower plate fabric layer (13) is the part that touches the bed frame, so it is important to prevent slipping. Therefore, it is preferable that it is a mesh material containing anti-slip fabric.

The middle zipper portion 12 is used by the user or manager to separate the outer shell portion from the inner foam mattress portion.

In particular, the upper fabric single layer 11, the zipper portion 12, and the lower fabric single layer 13 can be aesthetically pleasing to the user by applying a color scheme so that they can be distinguished by color alone, as shown in FIG. 1, and the zipper portion 12 ) so that you can easily check its location.

Next, with reference to FIGS. 2 and 3, the foam mattress portion inside the outer shell portion will be described.

The comfort portion 100 of the present invention is made of a temperature-insensitive memory foam material. Preferably, temperature-insensitive memory foam having a 25% indentation force deflection (IFD) value of 30 or less at -20°C can be used. The comfort part 100 uses temperature-insensitive memory foam, allowing it to maintain optimal hardness even in the cold winter.

The support portion 200 of the present invention uses a viscoelastic material among the various foam materials described above in the prior art. Viscoelastic material refers to a material that gradually recovers by containing both viscosity to resist change in shape and elasticity to restore.

The foam mattress consists of a comfort part 100 and a support part 200. The comfort part 100 consists of a total of two layers, and the support part 200 consists of a total of three layers.

The comfort part 100 is a part that is molded to fit the body shape when the user lies down, and functions to comfortably relax the body by making it as soft as desired.

If the comfort unit 100 is made of one layer, it may give an excessive feeling of being worn out, so it is preferable that it has two or more layers. However, if it has too many layers, it is not desirable because it may not be comfortable or may give a cutting feeling.

Here, the present inventors determined that two layers were most preferable.

As shown in Figure 3, when the user lies down, the part that descends the most is the buttocks when lying on the side. If only this part is considered, two layers may be desirable, but if the user tosses and turns while lying on the side, the lower part falls even further. Because it may descend, the support profile layer 201 is located below it.

Since the first comfort layer 110 is the part that comes into direct contact when the user lies down, the softest material is preferable. In other words, the first hardness of the first comfort layer 110 is preferably the lowest. However, if the material with the lowest hardness is excessively thick, it may fall apart when the user lies down, so it is preferable that the thickness of the first layer is slightly smaller.

The second comfort layer 120 is located at the bottom of the first comfort layer 110, and as described above with reference to FIG. 3, it reaches down to the buttocks when the user lies on his side. Therefore, considering the general human body size, the sum of the thicknesses of the first comfort layer 110 and the second comfort layer 120 is preferably 65 mm to 85 mm, and 75 mm is most preferred. Additionally, as described above, it is preferable that the thickness of the first comfort layer 110 is smaller than the thickness of the second comfort layer 120.

Since the second comfort layer 120 is a part of the first comfort layer 110 that is further pressed after being pressed by the user, it is preferably greater than the first hardness of the first comfort layer 110. In other words, it is preferable that the second hardness of the second comfort layer 120 is greater than the first hardness.

Unlike the comfort portion 100, the support portion 200 firmly supports the overall shape of the foam mattress and performs a function to prevent the product structure from being damaged. Of course, in addition to these functions, a certain degree of cushioning is necessary.

The support portion 200 is preferably composed of a support profile layer 201, a first support layer 210, and a second support layer 220.

The support profile layer 201 is a part that specifically supplements elasticity when the user tosses and turns. Accordingly, the third hardness of the support profile layer 201 is preferably greater than the second hardness. Considering the size of the human body when tossing and turning, the thickness is preferably 40 mm to 60 mm, and most preferably 50 mm.

In addition, the support profile layer 201 is preferably made of a profile foam material, and the upper surface of the support profile layer 201 has a curved shape with a plurality of grooves. This support profile layer 201 facilitates dispersion of body pressure, thereby providing comfort.

The first support layer 210 is located immediately below the comfort portion 100 and has elasticity, so it is desirable to perform a function of supplementing the restoring force of the comfort portion 100. In other words, it helps relieve shock when the user lies down and functions like a spring in a spring mattress. Therefore, as it is similar in function to the second comfort layer 120, the fourth hardness of the first support layer 210 is preferably the same as the second hardness, or greater than the second hardness and less than the third hardness.

In one embodiment, the first support layer 210 may be high-elasticity, low-hardness elastic foam. Accordingly, the user's body pressure is distributed, and when not in use, the foam layer is quickly restored due to high elasticity, allowing the foam mattress to maintain its shape.

In another embodiment, the first support layer 210 may be chemical latex or synthetic latex.

Since the second support layer 220 must hold the foam mattress at the end and has a similar function to the third comfort layer, it is preferable that the fifth hardness of the second support layer 220 is the same or similar to the third hardness. do.

This can be summarized in a table as follows.

2nd In the example according to foam mattress

In the second embodiment, unlike the first embodiment, the comfort portion 100 is composed of a total of three layers, the support portion 200 is composed of a total of two layers, and the inner fabric layer 10 is not included.

Figure 4 shows the upper plate fabric layer 11, the zipper portion 12, and the lower plate fabric layer 13, which are the outer skin parts of the foam mattress according to the present invention.

The upper plate fabric layer 11 is located on the upper side of the upper and side portions, and the lower plate fabric layer 13 is located on the lower side of the lower and side portions.

The upper plate fabric layer 11 and the lower plate fabric layer 13 are made of different materials because their functions are different.

Since the top fabric single layer 11 is a part that the user's body directly touches when lying down, it is desirable to secure spandex. Therefore, it is preferable that it is a knit material containing polyester.

The lower plate fabric layer (13) is the part that touches the bed frame, so it is important to prevent slipping. Therefore, it is preferable that it is a mesh material containing anti-slip fabric.

The middle zipper portion 12 is used by the user or manager to separate the outer shell portion from the inner foam mattress portion.

In particular, the upper fabric single layer 11, the zipper portion 12, and the lower fabric single layer 13 can be aesthetically pleasing to the user by applying a color scheme so that they can be distinguished by color alone, as shown in FIG. 1, and the zipper portion 12 ) so that you can easily check its location.

Next, with reference to FIGS. 5 and 6, the foam mattress portion inside the outer shell portion will be described.

The present invention uses a viscoelastic material among the various foam materials described above in the prior art. Viscoelastic material refers to a material that gradually recovers by containing both viscosity to resist change in shape and elasticity to restore.

The foam mattress consists of a comfort part 100 and a support part 200, where the comfort part 100 consists of a total of three layers, and the support part 200 consists of a total of two layers.

The comfort part 100 is a part that is molded to fit the body shape when the user lies down, and functions to comfortably relax the body by making it as soft as desired.

If the comfort unit 100 is made of one layer, it may give an excessive feeling of being worn out, so it is preferable that it has two or more layers. However, if it has too many layers, it is not desirable because it may not be comfortable or may give a cutting feeling.

Here, the present inventors determined that three layers were most preferable.

As shown in Figure 6, when the user lies down, the part that descends the most is the buttocks when lying on the side. If only this part is considered, two layers may be desirable, but if the user tosses and turns while lying on the side, the lower part falls even further. Because it may go down.

Since the first comfort layer 110 is the part that comes into direct contact when the user lies down, the softest material is preferable. In other words, the first hardness of the first comfort layer 110 is preferably the lowest. However, if the material with the lowest hardness is excessively thick, it may fall apart when the user lies down, so it is preferable that the thickness of the first layer is slightly smaller.

The second comfort layer 120 is located at the bottom of the first comfort layer 110, and as described above with reference to FIG. 3, it reaches down to the buttocks when the user lies on his side. Therefore, considering the general human body size, the sum of the thicknesses of the first comfort layer 110 and the second comfort layer 120 is preferably 65 mm to 85 mm, and 75 mm is most preferred. Additionally, as described above, it is preferable that the thickness of the first comfort layer 110 is smaller than the thickness of the second comfort layer 120.

Since the second comfort layer 120 is a part of the first comfort layer 110 that is further pressed after being pressed by the user, it is preferably greater than the first hardness of the first comfort layer 110. In other words, it is preferable that the second hardness of the second comfort layer 120 is greater than the first hardness.

The third comfort layer 130 is a part that specifically supplements elasticity when the user tosses and turns. Therefore, it is preferable that the third hardness of the third comfort layer 130 is greater than the second hardness. Considering the size of the human body when tossing and turning, the thickness is preferably 40mm to 60mm, and 50mm is most preferable.

Unlike the comfort portion 100, the support portion 200 firmly supports the overall shape of the foam mattress and performs a function to prevent the product structure from being damaged. Of course, in addition to these functions, a certain degree of cushioning is necessary.

The support portion 200 is preferably composed of a first support layer 210 and a second support layer 220.

The first support layer 210 is located immediately below the comfort portion 100 and has elasticity, so it is desirable to perform a function of supplementing the restoring force of the comfort portion 100. In other words, it helps relieve shock when the user lies down and functions like a spring in a spring mattress. Therefore, as its function is similar to the comfort second layer 120, it is preferable that the fourth hardness of the support first layer 210 is the same as the second hardness, or is greater than the second hardness and smaller than the third hardness.

In one embodiment, the first support layer 210 may be chemical latex or synthetic latex.

Since the second support layer 220 must hold the foam mattress at the end and has a similar function to the third comfort layer, it is preferable that the fifth hardness of the second support layer 220 is the same or similar to the third hardness. do.
