The present invention relates to a mattress for a bed, and more particularly, to a mattress configured with a plurality of cushion modules in which polyurethane foams and memory foams having different elasticities improve comfort, weight distribution effect, and durability.

Spring mattresses and sponge-type mattresses are commonly used for bed mattresses.

In the spring mattress, a plurality of coil springs having a constant elasticity are arranged uniformly. The loads of the coil springs vary according to the bending of the human body or the weight difference according to the position, so that the coils of the coil springs have different elasticity as time passes. It is lowered than the springs, which makes the durability less and makes the user feel uncomfortable instead of comfortable. Likewise, sponge-type mattresses have different loads continuously applied to different positions, and the elasticity of the sponges varies from position to position, and thus the load distribution effect is reduced.

Sponge-type mattress has a sponge, or cushion member, that elastically responds to load or pressure inside the cover, and the cushion member absorbs energy applied rapidly due to the impact and thus reduces the impact, that is, the cushion force. It is divided into hard and soft.

Most of the cushion member is composed of a monolithic sponge having a uniform density, and when a hard sponge, that is, a sponge having a high density, is used to support the body, but the cushioning force is weak, which may cause uncomfortable sleep, and vice versa.

Hereinafter, on the basis of the accompanying drawings an embodiment of the bed mattress according to the present invention will be described in detail.

In the present invention, two types of cushions are laminated to provide both comfort and support that are incompatible with each other but are incompatible with each other, and the stacked cushions are modularized to provide elastic force corresponding to the load for each body part. Form a mattress for the bed.

1 is a cross-sectional view of a cushion module composed of a high elastic polyurethane foam and a low elastic memory foam constituting a bed mattress according to an embodiment of the present invention.

The cushion module 10 constituting the mattress has a rectangular polyurethane foam member 11 having a width of 200 mm, a height of 150 mm, and a length of 1500 mm, a width of 200 mm, a maximum height of 50 mm, a length of 1500 mm, and a lengthwise direction. A vertically cut cross section is composed of a memory foam member 12 having two convex shapes, one of which is flat in the height direction and the other of which is equally divided, wherein the flat surface of the memory foam member 12 is the polyurethane foam. It is joined to and formed on the member 11. The polyurethane foam member 11 and the memory foam member 12 may be bonded with an environmentally friendly water-soluble adhesive that is harmless to the body.

Here, the length 1500mm of the polyurethane foam member 11 and the memory foam member 12 corresponds to a longitudinal length of a queen size (2000mm x 15000mm) mattress, and a double size and a single For a size bed, it can be 1400 mm and 1000 mm, respectively. The width 200mm of the polyurethane foam member 11 and the memory foam member 12 is divided into ten equal parts of 2000mm, which is the length of a queen-size mattress, and the width of the cushion module 10 is not limited to ten equal parts. It is possible to divide into equal parts, 20 equal parts, etc., and to divide the mattress into different values without dividing the length of the mattress. For example, some cushion modules 10 have a width of 200 mm and some cushion modules 10 have a width of 100 mm or 150 mm. Can also be produced.

The polyurethane foam member 11 and the memory foam member 12 are produced through a polymerization reaction in which a hydroxyl compound such as polyether polyol and an isocyanate are combined and a catalyst is added as an additive. Can be. These memory foams have a characteristic of slowly sinking while feeling the weight and body temperature of the human body, so that the pressure of the body is uniformly distributed and the weight is not concentrated in one place, so that the circulation of blood is smooth, which gives the user a sense of stability. do. On the contrary, when the load is removed, the circular shape is gradually restored to perfection. Since the restoring force is maintained for a long time, the durability is also excellent, and it is spotlighted by the patient who needs treatment of the neck or spine, as well as the person who wants perfect unloaded sleep. have.

In the present invention, the polyurethane foam member 11 and the memory foam 12 may be different in elasticity from each other by changing the physical configuration or additives. The polyurethane foam member 11 has a high elasticity, has latex-like properties and elongation of 220%, and the memory foam 12 is the polyurethane foam member 11. It has relatively low elasticity compared to).

That is, where the convex shape of the memory foam member 12 in the cushion module 10 is in contact with the body, the memory foam of the cushion module 10 distributes the load of the body with low elasticity and Even contact provides comfort and comfort, and a highly elastic polyurethane foam member 11 is formed below the memory foam member 12 to support it firmly to provide a feeling of supporting the body without being turned off.

The cushion module 10 of FIG. 1 is a roll type formed to have a length of 1000 mm, 1400 mm, 1500 mm, and the like in a length direction corresponding to the horizontal size of the bed, but the cushion module 30 of FIG. 4 has a maximum height of 150 mm in FIG. 1. It is the same as the cushion module 10, the length of the width direction and the longitudinal direction is similar cube type. The width and length of the cube type cushion module 30 may be determined by the size of the mattress, that is, the vertical length and the horizontal length. For example, in the case of a queen size mattress, the width and length of the cube type cushion module 30 may be It may be 100mm and 100mm, 100mm and 150mm, 200mm and 150mm, and in the case of a single size mattress, the width and length of the cube-type cushion module 30 may be 100mm and 100mm, 200mm and 200mm.

The cube-type cushion module 30 of FIG. 4 is also formed by combining two layers of the polyurethane foam member 31 and the memory foam member 32 similarly to FIG. 1, and the memory foam member of FIG. 32 is a rectangular parallelepiped shape in which the upper end (ie, the part far away from the polyurethane foam member 31) is parallel, and in (b), the upper end of the memory foam member 32 has a convex shape in which it protrudes. (C) has a cone shape in which the upper end of the memory foam member 32 protrudes only in the center portion.

The cube-type cushion module 30 of FIG. 4 may also be fitted and fixed to the inner cover 21 as shown in FIG. 3, but the plurality of cube-type cushions may be inserted into a pocket into which the roll-type cushion module 10 of FIG. 1 is fitted. The distance and the number of longitudinal gaps of the bag into which the cushion module 30 is fitted and the cushion module 30 is fitted may be determined by the length of the mattress and the width of the cube-type cushion module 30. For example, in the case of using a cushion module 30 having a width and a length of 100 mm and 150 mm in a 1500 mm x 2000 mm queen size mattress, the inner cover 21 has 20 pockets for fitting the cushion module 30. The gap may be 100 mm (only one cushion module is inserted in each pocket in the longitudinal direction) or 10 pockets may be provided and the gap may be 200 mm (insert two cushion modules in the vertical direction in each pocket).

FIG. 5 illustrates an embodiment of a bed mattress in which a cube-shaped cushion module 30 is coupled. As shown in FIG. 4 (b), a cushion module 30 having a shape of a portion cut out of a circular column is used. . 4 (b), the cushion module 30 is arranged differently from that in FIG. 2, and in FIG. 2, the direction of the valley and the hill formed by the upper convex shape of the memory foam member 12 is the transverse direction of the mattress, but FIG. 5. In the mattress in the direction of the valleys and mountains formed by the convex shape of the upper portion of the memory foam member 32 is the longitudinal direction of the mattress.

By using the cube type cushion module 30 as described above, the direction of the valley and the hill formed by the convex shape on the upper portion of the memory foam member 32 can be freely adjusted, for example, a cushion as shown in FIG. When the module 30 is used, the direction of the valleys and mountains are parallel to the edges of the mattress (to prevent the body from being pushed outward), and the valleys and mountains are horizontal in the mattress as shown in FIG. Alternatively, the cube type cushion module 30 as shown in FIG. 4B may be disposed to be formed in a vertical direction).

FIG. 6 shows an embodiment using memory foams of different densities depending on the longitudinal direction of the bed mattress.

The memory foam forming the top of the mattress has a different density depending on the ratio of isocyanate and polyether polyol. The density of the memory foam used in the mattress is about 70-90 kg / m 3 .

Since the mattress for a bed according to the present invention is formed of a plurality of cushion modules 10 and 30, memory foams having different densities may be used according to the position of the body, and the mattress receives a lot of load based on the longitudinal direction of the mattress. Cushion module with high density memory foam at the center, top, and bottom of the module, and low density memory foam at the low load (between the center, top, and bottom of the mattress). Can be applied. As shown in Figure 6, the cushion module (10, 30) using a high-density memory foam, such as 90kg / m 3 is applied to the buttocks (hips), head, legs near the most when lying down and the load is relatively small In the part, cushion modules 10 and 30 using a low density memory foam such as 70 kg / m 3 may be applied.

Therefore, the user can feel more comfortable by absorbing pressure in response to the load on which the mattress acts, and the durability is increased and the user can be used for a long time by effectively distributing and supporting the load.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. Addition or the like.
