The present invention relates to a functional memory foam, and more particularly to a memory foam and a molding mold for a magnet embedded therein.

Memory foam is a new material with an open cell structure that is completely different from conventional shaped products, and unlike viscous sponges, it is a viscoelastic, highly functional material with high density and energy absorption. Since the pressure relief characteristics of the memory foam respond to the temperature and weight of the human body, it is gradually shaped according to the overall contour of the human body when it is applied, and absorbs all the applied force while supporting it. It has the property of returning.

Memory foam is usually manufactured by foaming urethane, and is used for various purposes in the industrial field. In particular, various products are manufactured as pillows or bedding.

The bedding made of memory foam absorbs and distributes the load of the human body to protect the human body and take a good night's sleep. In particular, when sleeping badly for a long time, it can prevent the deformation of the cervical spine, and it senses the body temperature or weight of the human body and changes it evenly according to the shape. It does not interfere with blood circulation. In addition, it is relatively breathable and can suppress the growth of bacteria and mites, and maintains high resilience even after long use.

On the other hand, there are many attempts to obtain a health promoting effect by the magnetic field generated from the magnet by mounting a magnet on the bedding. For example, a magnet may be attached to or inserted into a floor bedding surface in the form of a plate.

If the magnet is to be included in the memory foam as in the example of the bedding including the magnet, the magnet may be attached to the surface and the cover may be completed by covering the cover.

1 is a perspective view illustrating an example of a memory foam used as a pillow, and it can be seen that a plurality of magnets 12 are attached to the surface of the memory foam 10. Since the memory foam is molded into a predetermined shape by injecting a raw material into the mold, it is difficult to include the magnet inside, so as to be attached to the surface of the memory foam through the adhesive 14 as shown in FIG. 2. none.

By the way, the magnet attached to the surface is easy to detach from the memory foam. In particular, if the shape is frequently deformed or the external pressure is excessively applied during use of the memory foam, the coupling force between the magnet and the memory foam will be further reduced. In addition, the magnet attached to the surface of the memory foam has a problem that can cause inconvenience to the body parts, such as the user's head can not properly utilize the advantages of the memory foam.

As a result, there are many problems to be solved yet to attain the efficacy of the memory foam and magnet at the same time.

The present invention was devised under such a technical background, and an object of the present invention is to provide a new type of functional memory foam in which a magnet is mounted inside a memory foam instead of a surface.

In addition, another object of the present invention is to provide a molding mold for manufacturing a memo reform that can embed a magnet in the memory foam manufacturing process without a subsequent process, such as partially cutting and inserting the memory foam.

Other objects and features of the present invention will be more clearly presented through the following detailed description and examples.

In order to achieve the above object, the present invention provides a memory foam main body molded into a mold having a predetermined shape, and includes a memory foam main body including a plurality of trench-shaped holes extending vertically from the surface of the memory foam main body. ; Provided is a functional memory foam incorporating a magnet including at least one magnet piece positioned at an inner end of the trench-shaped hole in the memory foam body and having a diameter larger than the diameter of the hole.

At least one surface of the memory foam body may be formed as a curved surface. The magnet piece is preferably embedded in a depth of 2 ~ 10 cm from the surface of the memory foam body. More preferably, it is appropriate to arrange the inner central portion in the thickness direction of the memory foam body. The magnet piece disposed therein can be improved in durability even if it is used for a long time without changing the position, and can prevent the user from feeling inconvenience that the magnet piece is closed on the head.

The magnet piece is preferably in the form of a disk having a diameter of at least twice as large as the diameter of the hole in the trench form.

The memory foam body may be formed of a curved surface having a different upper surface, in which case the magnet piece is preferably embedded at the same depth from the surface.

The present invention also includes a first mold and a second mold having an internal space of a predetermined shape as a molding mold for manufacturing the memory foam, wherein at least one of the first mold and the second mold extends from the surface to protrude A plurality of pillar-shaped protrusions are disposed, and the protrusions are formed of a metal material to provide a memory foam molding mold.

Hereinafter, the present invention will be described with reference to the drawings and preferred embodiments. However, the present invention is not limited to the exemplary embodiments described, and various modifications and improvements may be made at the level of those skilled in the art.

Referring to FIG. 3, the memory foam 20 according to the present invention has a plurality of holes in a main body surface, the holes extending in a vertical direction from the main body surface inward to a predetermined length. That is, the hole corresponds to the trench 25 in the form of a trench, as can be seen in FIG. The trench holes may be arranged at predetermined intervals according to the number required for the memory foam, and may be concentrated at the center of the memory foam or additionally disposed at the left and right sides of the center. The trench hole 25 preferentially improves the elasticity of the memory foam and serves as a kind of air layer to double the cushioning force when the memory foam is used as a pillow or a mattress.

In addition, the trench hole 25 serves to position the magnet piece 30 at the lower end thereof and fix the magnet piece so as not to move to another position. Such magnet piece positioning and fixing functions will be described later.

As shown in FIG. 4, the magnet piece 30 is positioned at the lower end of the trench hole 25, that is, the trench hole extends inward from the surface of the memory foam and meets the interior of the memory foam. As such, the magnet piece 30 is positioned at the lower end of the trench hole 25 to be stably fixed inside the memory foam, and no further position shift occurs. Therefore, the magnet piece is fixed at a fixed position even when the shape of the memory foam is deformed or an excessive external pressure is applied.

5 is a side cross-sectional view of the memory foam according to the present invention. The memory foam 20 is formed as a curved surface as a whole, such a shape may be variously modified depending on the purpose of use. That is, it may be transformed into a pillow form, a cuboid cushion form, a mattress form, and the like.

According to the embodiment shown in FIG. 5, one side 20a of the memory foam is high and the other side 20b is formed low. Thus, the height difference form can increase the ergonomic convenience when using the memory foam pillow.

The plurality of trench holes 25 extending vertically from the surface of the memory foam are spaced apart from each other at predetermined intervals, and the magnet piece 30 is positioned at the lower end thereof. The trench holes are all formed to have the same length t, and thus, the magnet pieces are also bent along the dotted line 'I' like the surface shape of the memory foam. The trench hole 25 preferably extends from the surface of the memory foam to approximately the center portion, and the length t to the depth of the trench hole are preferably in the range of at least 2 cm and 10 cm. If less than 2cm may increase the possibility of the magnet piece coming out of the trench hole, if it exceeds 10cm may be difficult in the process of removing the memory foam from the mold after injecting and curing the raw material into the memory foam molding mold.

The magnet piece 30 is preferably in the form of a flat disk, and in some cases, may be formed in the shape of a polygon. The diameter (D) of the magnet piece 30 should be formed larger than the diameter (d) of the trench hole 25, preferably, the ratio of the diameter is at least twice or more different. As the diameter of the trench hole is smaller than the diameter of the magnet piece, the magnet piece can be more stably fixed, thereby increasing durability of the memory foam in which the magnet is embedded.

The type of magnet used in the memory foam of the present invention is not limited, and a magnet piece including natural ore may be used instead of a single magnet piece.

6 exemplarily shows a mold 50 for forming a memory foam of the present invention. The mold includes an upper mold 50a and a lower mold 50b, each of which has a predetermined shape of space therein. (For convenience, the upper mold 50a is shown below in FIG. 6.)

On the inner surface of the upper mold 50a, protrusions 55 having a cylindrical shape having a predetermined diameter are disposed to be spaced apart from each other. The protrusion 55 is formed in a shape corresponding to the trench hole 25 of the memory foam of the present invention. That is, the diameter and height of the protrusion 55 determine the diameter and depth of the trench hole 25. On one side of the upper mold 50a (or one side of the lower mold), a raw material injection hole 58 of a memory foam is formed.

The protrusion 55 is preferably formed of a metal material. In this case, the magnet piece can be strongly attached to the protrusion without using a separate binder.

In such a state that the molds 50a and 50b are coupled to each other as shown in FIG. 7, the raw material of the memory foam is injected through the injection hole 58. When the magnet piece 30 is placed on the protrusion part 55 in advance, the magnet piece is strongly attached to the protrusion part of the metal material and is fixed by magnetic force. Thus, as shown by arrows in FIG. 7, a raw material is injected into the mold to form a closed space. Even if it is fully filled, the position of the magnet piece does not change.

After the mold is finally removed, as shown in FIG. 5, the magnet piece is embedded in the memory foam and fixedly positioned.

As a result, the memory foam according to the present invention may be manufactured in a single process without the hassle of inserting a magnet after the completion of the memory foam and embedding the magnet without a partially cut region.

Functional memory foam of the present invention described in detail above will be possible to apply and improve in various forms at the level of those skilled in the art without changing the nature of the claims to be described later.

According to the present invention, a functional product having a magnet embedded in a memory foam is provided. The memory foam not only changes the position of the magnets disposed inside or escapes out of the memory foam, but also improves the durability of the product, and provides a comfort so that the user cannot physically feel the presence of the magnets in the memory foam. Therefore, it is possible to maximize the user's convenience because it can simultaneously enjoy the advantages of the memory foam and the positive effect on the human body of the magnet.

The memory foam according to the present invention may be effectively applied to a pillow, a mattress, or the like, as well as cushions, auxiliary cushions for automobiles, indoor soundproof walls, and the like.
