Description

Customized mattresses by weight{CUSTOMIZED MATTRESS BY WEIGHT}

The present invention relates to a customized mattress for each weight, and more particularly, to a customized mattress for each weight that has a different support for each weight and can be selected according to the 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 into the interior 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, which makes it less transportable or less mobile. In the case of long-term use, the spring is partially damaged or the spring's performance deteriorates. There is a problem that a difference occurs.

In recent years, as interest in health increases, latex products manufactured as mattresses by foaming natural rubber have been widely marketed and purchased by consumers with excellent performance and good recognition. However, as for natural rubber, the international price fluctuations of raw materials have a large effect on the price of the product. Therefore, 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 Laid-Open Publication No. 10-2019-0028159, among mattresses using such polyurethane foam, the sponge body is placed on top of the sponge body in either a width direction or a length direction, at regular intervals so that the sponge body has an air circulation structure. A mattress is provided with a formed first concave portion, and a second concave portion formed at regular intervals in a direction perpendicular to the first concave groove in the lower portion of the sponge body, which is a memory foam and air circulation for improving resilience in the sponge body. It is a composite structure with filter foam for excellent stability, load distribution, and smooth air circulation.

In addition, according to Korean Patent Publication No. 10-1934063, a mattress for a bed in which an interior material laminated to have a certain cushion is wrapped with a fabric cover is disclosed, wherein the interior material has a density of 600-1,200 kg/㎥, and a shore hardness tester It is characterized by including a plurality of cushion layers in which at least one polyurethane elastomer pad layer having a hardness of 0 Shore 00 to 90 Shore 00 and an elongation of 200-1,500% is inserted.

However, the present invention relates to the provision of a customized mattress for each weight that can be selected according to the user's weight and has different support for each weight. In particular, when a heavy person and a light person lie together in one bed, the mattress is It is intended to solve the problem that a light person tilts toward a heavy person, and the above prior patents do not find any worries about such problems or solutions. Therefore, in order to provide a more comfortable and comfortable bed, the weight of the present invention The development of a customized mattress is urgently required.

The present invention has been developed in order to solve the above problems, and has a main object to provide a customized mattress for each weight that can be selected according to the weight of the user and has a different support for each weight.

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

Here, the mattress is provided as a mattress for one or two persons, and the upper pad, the middle pad, and the lower pad may be formed of a single layer or two or more layers, respectively. In addition, the middle layer first pad and the middle layer second pad are configured such that the difference between the density and the hardness value is greater than a predetermined value, the middle layer first pad is made of a harder material than the middle layer second pad, and the middle layer second pad The pad is made of a material that is softer than that of the first intermediate pad so that the soft part is compressed before the hard part.

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

According to the above features, in the present invention, since the first middle pad and the second middle pad use polyurethane foams having a very large difference in density and hardness values, the upper middle layer first pad is The lower middle layer second pad, which is a relatively soft part, is first pressed in the state of supporting it, so that the user lying on the mattress feels more comfortable as if floating in water.

In addition, according to the present invention, even if a person with a heavier weight and a light person lie down together in one bed, the mattress tilts to either side by setting different thickness ratios of the middle layer pads having different density and hardness values on the left and right sides. Can be prevented, and through this, a comfortable sleep can be provided to all users.

Hereinafter, the present invention will be described in more detail through the accompanying drawings and embodiments.

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

In the following description, the illustration and description are omitted except for inevitable parts in the description of the invention, and the same reference numerals are assigned to the same and similar elements throughout the specification, and detailed descriptions thereof will be omitted without repetition.

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

1 is an exemplary form of a customized mattress for each weight according to the present invention, and shows a case in which the present invention is applied to a mattress for one person. Here, the upper pad is composed of an upper first pad (UL ₁ ) and an upper layer second pad (UL ₂ ) from the top, and the middle pad is a middle layer first pad (ML ₁ ) and a middle layer second 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 in a multilayer structure of two or more layers as well as a single layer, and the upper pad and the intermediate pad may be provided in a single layer or a multilayer structure.

In the weight-specific mattress of the present invention, the first middle pad (ML ₁ ) and the second middle 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 with a density of 42 kg/㎥ (±1~2) and hardness of 5 (±1~2) can be used.

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

First, a flat test piece is placed on the object of the tester, and a load of 0.5 kg is applied in advance while a circular pressure plate 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 press, the circular plate is compressed to 75% of the initial thickness at a speed of 50 mm/min, then the load is immediately removed, and the load is compressed again to 25% of the initial thickness, stopped for 20 seconds, and the load is measured. And decide.

That is, the determined hardness value represents the load when a polyurethane foam having a thickness of 50 mm is compressed to 25% of the initial thickness at a rate of 50 mm/min with a circular pressure plate having a diameter of 20 cm, and the unit is kg/314 cm2. Therefore, 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 pad (ML ₂ ) use polyurethane foams having a very large difference in density and hardness values, in this case, the first intermediate pad (ML ₁ ). While the material is much harder than that of the second middle pad (ML ₂ ), the second middle pad (ML ₂ ) uses a polyurethane foam that is much softer than the first middle pad (ML ₁ ). In this configuration, when weight is applied to the middle layer pad due to the user lying on the mattress, the second middle layer pad (ML ₂ ) on the lower side, which is a soft part, is compressed first, and the upper middle layer system, which is a hard part, is compressed. 1 This is to use the laws of physics in which the pad (ML ₁ ) is compressed later, and the soft part of the lower part is pressed before the hard part of the upper part, so the user lying on the mattress feels as if they are in zero gravity or floating on the water. You can feel very comfortable.

In addition, the first middle pad (ML ₁ ) and the second middle pad (ML ₂ ) are preferably configured to have different thicknesses (Thickness; mm) according to the user's weight, and the change in such thickness is shown in Table 1 below. And as illustrated in FIG. 2.

FIG. 2 exemplarily shows the standard for calculating the thickness of each weight of the first middle pad and the second middle pad in the configuration of a customized mattress according to weight of the present invention. Referring to Table 1 above, the first middle pad (ML ₁₎ ) And the thickness (T) of the middle layer pad including the second middle pad (ML ₂ ) is 120 mm, which is the first middle layer pad (ML ₁ ) positioned above and the second middle layer pad positioned below ( It coincides with the sum of ML ₂ ).

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

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

On the other hand, in the example above, the middle layer first pad (ML ₁ ) with a density of 60 kg/㎥ (±1 to 2) and a hardness of 14 (±1 to 2), a density of 42 kg/㎥ (±1 to 2), and a hardness of 5 ( Based on the use of the second middle pad (ML ₂ ) of ±1 to 2), the standard for calculating the thickness for each weight of the first middle pad and the second middle pad was described, but the present invention is not limited thereto, and the user's weight Depending on the density (Density) and hardness (Hardness) values may be defined to be different.

For example, if the user's weight is 50kg, for example, a polyurethane foam with a density of 50kg/㎥ (±1~2) and a hardness of 12 (±1~2) is used as the middle layer first pad (ML ₁ ). , It can be defined to use a polyurethane foam having a density of 35 kg/㎥ (±1~2) and a hardness of 4 (±1~2) as the second middle layer pad (ML ₂ ). In addition, when the user's weight is 80kg, for example, a polyurethane foam having a density of 80kg/㎥ (±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/㎥ (±1~2) and a hardness of 7 (±1~ ₂ ) as the second middle layer pad (ML ₂ ).

The upper pad may be formed of an upper first pad UL ₁ , or both the upper first pad UL ₁ and the upper second pad UL _{2 as a} memory foam. In this case, since the memory foam gently wraps the user's body and distributes the weight, it is possible to provide a comfortable and comfortable sleeping place for the user. In addition, the lower pad LL is preferably made of a somewhat harder material 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 made of one It is possible to provide not only a single layer of pads, but also a multi-layered structure consisting of first and second pads.

The technical idea of the customized mattress for each weight according to the present invention can be applied to the mattress for two persons shown in FIG. 3. 3 shows another embodiment of a customized mattress for each weight of the present invention configured according to the thickness calculation standard of FIG. 2, and shows a case in which the present invention is applied to a mattress for two.

The two-person mattress is in the form of a mattress that allows two people to lie down. Like the one-person mattress of FIG. 1, the upper pad consists of an upper first pad (UL ₁ ) and an upper second pad (UL ₂ ) from the top, and the middle layer The pad includes a first middle pad ML ₁ and a second middle pad ML ₂ from the top, and the lower pad LL is provided as a single layer. Of course, even in this case, the upper pad, the middle pad, and the lower pad LL may be provided in a multilayer structure as well as a single layer.

However, the upper pad and the lower pad LL are configured to have the same characteristics on one surface without any distinction between the user 1's use area and the user 2's area, respectively, whereas the middle layer pad is the user 1's area and user 2's. There is a difference in that the use area is divided and configured to have different characteristics on one surface. That is, the middle-layer pad is configured by partitioning on one surface so that the area of use of User 1 and the area of use of User 2 have different characteristics according to the weight of users. 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 It can 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. Although it may be, in this embodiment, a middle layer first pad (ML ₁ ) having a density of 60 kg/m 3 (± 1 to 2) and a hardness of 14 (± 1 to 2) and a density of 42 kg/m 3 (± 1 to 2), The thickness of the first and second intermediate pads (ML ₁ ) (ML ₂ ) constituting the user 1's area of use based on the case of using the second intermediate pad (ML ₂ ) of hardness 5 (±1~2) The ratio and the thickness ratio of the middle layer first and second pads ML ₁ and ML ₂ constituting the use area of the user 2 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 thicknesses of the first middle pad ML ₁ and the second middle pad ML ₂ in the area of use of User 1 are 30T (mm) and 90T (mm), respectively. ), the sum of the two can be adjusted to 120T (mm). In addition, since the weight of user 2 on the right is 80 kg, the thickness of the middle layer first pad ML ₁ and the middle layer second pad ML ₂ in the area of use of user 2 can be configured to be 60T (mm), respectively.

In this configuration, even if a person with a heavy weight and a light person lie down in one bed, the mattress tilts to either side by setting the thickness ratio of the middle layer pads having different density and hardness values on the left and right sides differently. Can be prevented, and through this, a comfortable bed can be provided to all users.

Meanwhile, the upper pad may be formed of an upper first pad UL ₁ , or both of the upper first pad UL ₁ and the upper second pad UL _{2 as a} memory foam. In this case, since the memory foam gently wraps the user's body and distributes the weight, it is possible to provide a comfortable and comfortable sleeping place for the user. In addition, the lower pad LL is preferably made of a somewhat harder material 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 made of one It is possible to provide not only a single layer of pads, but also a multi-layered structure consisting of first and second pads.
