Customized foam mattress by weight {CUSTOMIZED FOAM MATTRESS BY WEIGHT}

The present invention relates to a mattress customized for each body weight, and more particularly, to a customized foam mattress for each body weight, which has a different bearing capacity for each body weight and can be selected according to a user's weight.

In general, a mattress provides a certain cushioning feeling so that a user can take a comfortable rest or sleep, and is manufactured by inserting a spring therein or using foams of various materials. In particular, in the case of a mattress with a built-in spring, the price is high and its own weight is heavy, so transport or mobility is poor. There is a problem with the difference.

Recently, as interest in health increases, latex products manufactured as mattresses by foaming natural rubber are marketed and purchased by consumers with excellent performance and good recognition. However, since the international price fluctuations of natural rubber have a large effect on the product price, mattresses using high-density polyurethane foam that can provide similar physical properties while overcoming the disadvantages of natural rubber are becoming increasingly popular.

According to Korean Patent Application Laid-Open No. 10-2019-0028159 among mattresses using such polyurethane foam, the upper portion of the sponge body has an air circulation structure in any one of the width direction and the length direction, at regular intervals. There is provided a mattress in which a first recess is formed, and a second recess is formed at a predetermined interval in a direction perpendicular to the first recess in a lower portion of the sponge body, which is provided in the sponge body with memory foam and air circulation for improving stability. It is characterized by a composite structure of filter foam for

In addition, according to Korean Patent Publication No. 10-1934063, there is disclosed a bed mattress in which an interior material laminated to have a certain cushion is wrapped with a fabric cover, wherein the interior material has a density of 600 to 1,200 kg/m3, and a shore hardness tester The hardness measured as 0 Shore 00 ~ 90 Shore 00 is characterized in that it includes a plurality of cushion layers in which at least one polyurethane elastomer pad layer having an elongation of 200 to 1500% is inserted.

However, the present invention relates to the provision of a customized mattress for each body weight, which has different bearing capacity for each body weight and can be selected according to the user's weight. In particular, when a heavy person and a light person lie together in one bed, the mattress This is to solve the problem that the light person leans toward the heavy person, and the above prior patents do not find any concerns about this problem or the solution problem, so in order to provide a more comfortable and comfortable bed, the The development of customized mattresses is urgently required.

The present invention was developed to solve the above problems, and a main object of the present invention is to provide a customized foam mattress for each body weight, which has a different bearing capacity for each body weight and can be selected according to the user's weight.

According to one aspect of the present invention for achieving the above object, as a customized mattress for each body weight that has a different bearing capacity for each body weight and can be selected according to the user's weight, an upper pad positioned on the upper layer and a middle layer pad positioned in the middle, and It consists of a lower pad positioned at the bottom, wherein the middle layer pad is composed of a first intermediate pad and a second intermediate pad from the top, and the first intermediate pad and the second intermediate pad have different density and hardness values, In addition, there is provided a mattress customized for each body weight, characterized in that it has a change in thickness relative to each other in a predetermined numerical range according to the user's weight.

Here, the mattress is provided as a single or two-person mattress, and the upper pad, the middle pad, and the lower pad may each be formed of a single layer or a multilayer of two or more layers. In addition, the middle-layer first pad and the second intermediate-layer pad are configured such that the difference in density and hardness values is greater than or equal to a predetermined value, wherein the first intermediate-layer pad uses a harder material than the intermediate-layer second pad, and the second intermediate-layer pad The pad is configured such that the soft part is compressed before the hard part by using a material that is softer than that of the first intermediate pad.

According to the present invention, the two-person mattress is configured such that the upper pad and the lower pad have the same characteristics on one surface without distinction between the user 1's use area and the user 2's use area, respectively, whereas the middle layer pad is the user The use area of user 1 and the use area of user 2 are partitioned and configured to have different characteristics on one surface according to the weight of the users, the middle-layer first pad and the middle-layer second forming the use area of user 1 on the same surface It is preferable that the thickness ratio of the pad and the thickness ratio of the first middle pad and the middle layer second pad constituting the user 2's use area be different from each other.

According to the above features, the present invention uses polyurethane foams with a very large difference in density value and hardness value for the middle layer first pad and the middle layer second pad. The lower middle-layer second pad, which is a relatively soft part, is pressed first while supporting the mattress, so that the user lying on the mattress can feel more comfortable as if floating on water.

In addition, according to the present invention, even when a person with a heavy weight and a person with a light weight lie down together in one bed, the mattress tilts to one side by setting the thickness ratio of the middle layer pad having different density and hardness values on the left and right sides differently. can be prevented, and through this, it is possible to provide a comfortable sleep for all users.

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

In the following embodiments, the illustration and description will be omitted except for essential parts in describing the invention.

In the following description, the illustration and description are omitted except for essential parts in describing the invention, and the same reference numerals are given to the same and similar elements throughout the specification, and the detailed description thereof will be omitted without repeating.

The mattress customized for each body weight of the present invention is provided as a mattress for one or two persons, and is basically composed of an upper pad positioned on the upper layer, a middle layer pad positioned in the middle, and a lower layer pad positioned at the bottom. In addition, the upper pad, the middle pad, and the lower pad are made of polyurethane foam, and may be formed of one or two or more layers, respectively.

1 is an exemplary form of a mattress customized for each body weight according to the present invention, and shows a case in which the present invention is applied to a single-person mattress. Here, the upper pad includes an upper first pad UL ₁ and an upper second pad UL ₂ from the top, and the middle pad is a first middle pad ML ₁ and a second middle pad ML _{2 from the top.} ), and the lower pad LL consists of one single layer. Of course, as described above, the lower pad LL may be provided not only as a single layer but as a multi-layer structure of two or more layers, and in the case of the upper pad and the middle-layer pad, it may be provided as a single layer or a multi-layer structure.

In the mattress customized for each body weight of the present invention, the middle-layer first pad (ML ₁ ) and the middle-layer second pad (ML ₂ ) are preferably configured to have different characteristics, that is, different density and hardness values. together, for example, the first intermediate pad (ML ₁₎ a density 60㎏ / ㎥ (± 1 ~ 2 ), hardness 14 (± 1 ~ 2) using a polyurethane foam, and the middle layer of the second pad ₍₂ ML) Polyurethane foam of density 42kg/m3 (±1~2) and hardness of 5(±1~2) can be used as

Here, the hardness values of the first middle-layer pad ML ₁ and the middle-layer second pad ML ₂ represent the Rockwell hardness, and the middle-layer first pad ML ₁ and the middle-layer second pad ML ₂ . The criteria for calculating the hardness value of is as follows.

First, a flat test piece is placed on the target of the testing machine, and a load of 0.5 kg is applied in advance while a circular platen is placed on the upper surface of the test piece, and the thickness of the test piece at this time is defined as the initial thickness. Next, as a preliminary pressurization, the circular platen was compressed to 75% of the initial thickness at a speed of 50 mm/min, and then the load was immediately removed, and the load was then compressed again to 25% of the initial thickness, stopped in that state for 20 seconds, and then the load was measured. to determine

That is, the determined hardness value represents the load when a 50 mm thick polyurethane foam is compressed to 25% of the initial thickness at a speed of 50 mm/min with a circular pressure plate having a diameter of 20 cm, and the unit is kg/314 cm 2 . Thus, hardness 1 corresponds to 1kg/314cm2, hardness 5 corresponds to 5kg/314cm2, and hardness 14 corresponds to 14kg/314cm2.

As such, the first intermediate pad (ML ₁ ) and the second intermediate layer pad (ML ₂ ) use polyurethane foams having a very large difference in density value and hardness value, respectively. In this case, the first intermediate layer pad (ML ₁ ) is much harder than that of the second middle-layer pad (ML ₂ ), whereas the second intermediate-layer pad (ML ₂ ) uses a polyurethane foam that is much softer than the first intermediate-layer pad (ML _{1 ).} In this configuration, when weight is applied to the middle-layer pad due to the user lying on the mattress, the soft (soft) lower middle-layer second pad (ML ₂ ) is compressed first, and the upper middle-layer agent, which is the hard part, is first compressed. 1 This is to use the laws of physics where the compression of the pad (ML ₁ ) is made later. The soft part of the lower part is pressed before the hard part of the upper part, so that the user lying on the mattress feels as if he is in weightlessness or floating on water. You will feel very comfortable.

In addition, the middle-layer first pad (ML ₁ ) and the middle-layer second pad (ML ₂ ) are preferably configured to have different thicknesses (Thickness; mm) according to the weight of the user. and as illustrated in FIG. 2 .

2 exemplarily shows the thickness calculation criteria for each weight of the middle-layer first pad and the middle-layer second pad in the weight-specific customized mattress configuration of the present invention. Referring to Table 1 above, the middle-layer first pad (ML ₁₎ ) and _{the thickness T of the middle-layer pad including the second} intermediate-layer pad ML 2 is exemplified as 120 mm, which is the intermediate-layer first pad ML ₁ located on the upper portion and the intermediate-layer second pad located on the lower side ( ML 1 ). It coincides with the sum of _{ML 2 ).}

For example, as shown in Table 1, when _{the thickness of the first middle-layer pad ML 1} is 10T (mm) for a user weighing 30 kg or less, the thickness of the middle-layer second pad ML ₂ is 110T (mm) ) so that the sum of these two becomes 120T (mm). In addition, for a user weighing 100 kg _{, when the thickness of the first middle-layer pad (ML 1} ) is 80T (mm), the thickness of the middle-layer second pad (ML ₂ ) is 40T (mm), and the sum of these two is 120T (mm). In addition, when the user's weight exceeds 140 kg, _{the thickness of the first middle-layer pad (ML 1} ) having high hardness and density is 120T (mm), and the thickness of the second middle-layer pad having low hardness and density is 0T (mm) So, the sum of these two can be adjusted to 120T.

Therefore, as shown in Figure 1, the density of 60 kg / ㎥ (± 1-2), the hardness of 14 (± 1-2) of the middle-layer first pad (ML ₁ ) and the density of 42 kg / ㎥ (± 1-2), the hardness of 5 (±1~2) of the middle-layer second pad (ML ₂ ) constitutes the middle-layer pad and the user's weight is 60 kg, the middle-layer first pad (ML ₁ ) is made of polyurethane foam with a thickness of 40T (mm), and The middle layer second pad (ML ₂ ) may use a polyurethane foam having a thickness of 80T (mm).

_{On the other hand, in the above example, the middle-layer first pad (ML 1} ) with a density of 60 kg/m3 (±1~2) and a hardness of 14 (±1~2), a density of 42kg/m3 (±1~2), and a hardness of 5( The thickness calculation criteria for each weight of the first middle pad and the second middle pad have been described based on the use of the middle-layer second pad ML _{2 of ±1-2), but the present invention is not limited thereto, and the user's weight} It can also be defined to have different values of density and hardness depending on the .

As an example, if the user's weight is 50 kg, for example, as a middle-layer first pad (ML ₁ ), a polyurethane foam having a density of 50 kg/m3 (± 1-2) and a hardness of 12 (± 1-2) is used, and , It can be defined to use a polyurethane foam having a density of 35 kg/m 3 (±1 to 2) and a hardness of 4 (±1 to 2) as the middle-layer second pad (ML _{2 ).} In addition, when the user's weight is 80 kg, for example, a polyurethane foam having a density of 80 kg/m 3 (± 1-2) and a hardness of 19 (± 1-2) is used as the _{middle-layer first pad (ML 1 ),} It may be defined to use a polyurethane foam having a density of 56 kg/m 3 (±1 to 2) and a hardness of 7 (± 1 to ₂ ) as the middle-layer second pad (ML 2 ).

The upper pad may include an upper first pad UL ₁ , or both of the upper first pad UL ₁ and the upper second pad UL ₂ are made of memory foam. In this case, the memory foam gently wraps the user's body and distributes the weight, so that a comfortable and cozy sleep can be provided to the user. In addition, it is preferable that the lower pad LL be made of a material somewhat harder than the upper pad or the middle pad in order to establish a certain angle when covering the mattress lower cover. In this case, the upper pad and the lower pad are one It is possible to provide not only a single layer of pads, but also a multilayer structure including the first and second pads.

The technical idea of the mattress customized for each body weight according to the present invention is also applicable to the mattress for two people shown in FIG. 3 . 3 shows another embodiment of the customized mattress for each body weight of the present invention configured according to the thickness calculation criteria of FIG. 2, and shows a case in which the present invention is applied to a two-person mattress.

For two mattresses is a mattress, a form configured so that two people can lie down, also as in the first quotation mattress of the first upper pad is constructed from top to upper first pad (UL ₁₎ and the top layer the second pad (UL _2), the intermediate The pad is composed of the first middle pad ML ₁ and the middle layer second pad ML ₂ from the top, and the lower pad LL is provided as one single layer. Of course, even in this case, the upper pad, the middle pad, and the lower pad LL may be provided not only as a single layer but also as a multilayer structure.

However, the upper pad and the lower pad LL are each configured to have the same characteristics on one surface without distinguishing between the user 1 and user 2 use areas, whereas the middle layer pad has the user 1 use area and the user 2 use area. There is a difference in that the use area is partitioned and configured to have different characteristics on one surface. That is, the middle-layer pad is configured by dividing the use area of user 1 and the use area of user 2 according to the weight of the users on one surface so that they have different characteristics. 1, the thickness ratio of the pad (ML ₁₎ and the middle layer the second pad (ML ₂₎ intermediate the first pad (ML ₁₎ and the middle layer the second pad (ML ₂₎ constituting the thickness ratio, and the use area of the user 2 are each may be configured differently.

Of course, the middle-layer first pad ML ₁ and the middle-layer second pad ML ₂ in each use area are defined to have different density and hardness values according to the user's weight, as described above. It may be, but in this embodiment, a density of 60 kg/m 3 (± 1 to 2), a first middle-layer pad (ML ₁ ) having a hardness of 14 (± 1 to 2) and a density of 42 kg/m 3 (± 1 to 2), Thickness of _{the first and second middle-layer pads (ML 1} ) (ML ₂ ) constituting the user 1's use area based on the case of using the middle-layer second pad (ML _{2 ) having a hardness of 5 (± 1-2)} The ratio and the thickness ratio of the first and second middle-layer pads ML ₁ and ML ₂ constituting the user 2's use area will be described with reference to Tables 1 and 2 above.

According to FIG. 3 , since the weight of user 1 on the left is 50 kg, _{the thickness of the first middle-layer pad (ML 1} ) and the middle-layer second pad (ML ₂ ) in the use area of user 1 is 30T (mm) and 90T (mm), respectively. ), and the sum of these two can be adjusted to 120T (mm). In addition, since the weight of the user 2 on the right is 80 kg, _{the thicknesses of the first middle-layer pad ML 1} and the middle-layer second pad ML ₂ in the user 2 use area can be configured to be 60T (mm), respectively.

In this case, even if a person with a heavy weight and a person with a light weight lie down together in one bed, the phenomenon that the mattress tilts to one side is prevented by setting the thickness ratio of the middle layer pad having different density and hardness values on the left and right sides differently. This can be prevented, and through this, it is possible to provide a comfortable sleep for all users.

Meanwhile, the upper pad may include an upper first pad UL ₁ , or both of the upper first pad UL ₁ and the upper second pad UL ₂ are made of memory foam. In this case, the memory foam gently wraps the user's body and distributes the weight, so that a comfortable and cozy sleep can be provided to the user. In addition, it is preferable that the lower pad LL be made of a material somewhat harder than the upper pad or the middle pad in order to establish a certain angle when the mattress lower cover is covered. In this case, the upper pad and the lower pad are one It is possible to provide not only a single layer of the pad, but also a multilayer structure including the first and second pads.
