Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a pillow formed by laminating resin foams.

[0002]

2. Description of the Related Art Pillows such as registered utility model publication No. 3033375 using resin foam such as urethane foam have been proposed. This pillow is manufactured by foaming a resin in a mold having a pillow-shaped cavity. However, since the resin foam has poor air permeability, heat from the head is trapped inside and stuffy, giving discomfort during use.

For this reason, conventionally, a structure is used in which a large number of air holes are formed in a resin foam or a natural material having air permeability is arranged inside to thereby release heat.

[0004]

However, in the case of forming the ventilation holes, there is a problem that the processing for forming the holes is troublesome, the cost is high, and the appearance is deteriorated. Similarly, when using a natural material, the cost is high and the structure is complicated. Also, natural materials require care to maintain breathability,
It has a problem that it cannot be used easily.

The present invention has been made in view of the above-mentioned conventional problems, and is simple in that it has a breathable structure, can be manufactured at low cost, and requires no maintenance. The purpose is to provide a convenient pillow.

[0006]

In order to achieve the above object, the invention of claim 1 comprises a main body on which a plurality of low resilience foams are laminated, and a continuous foam disposed between the main bodies. It is characterized by comprising a breathable foam.

According to a second aspect of the present invention, there is provided the pillow according to the first aspect, wherein an end face of the breathable foam is exposed.

According to a third aspect of the present invention, there is provided the pillow according to the first or second aspect, wherein an inflatable airbag is provided inside the breathable foam.

According to a fourth aspect of the present invention, there is provided the pillow according to any one of the first to third aspects, wherein the breathable foam is disposed between the low-resilience foams.

According to a fifth aspect of the present invention, there is provided the pillow according to any one of the first to third aspects, wherein the breathable foam is laminated on an upper part of the low resilience foam.

[0011]

According to the first aspect of the present invention, since the main body is made of the low resilience foam, a soft feeling and hardness are imparted to the pillow. Then, by setting the hardness, the sag is reduced, and the outer shape of the main body can be favorably maintained.

Further, since the air is imparted by the air-permeable foam to prevent heat from being trapped, the heat applied from the head can be quickly removed and the head can be used comfortably.

Further, the structure in which the air permeable foam and the main body of the low resilience foam are laminated can continuously maintain the air permeability of the air permeable foam, so that troublesome care is not required. In addition, since it has a laminated structure and a simple structure, it can be manufactured easily and inexpensively.

According to the second aspect of the present invention, since the end face of the gas permeable foam is exposed, heat can be easily externally released from the exposed end face. For this reason, heat can be reliably released and stuffiness does not occur.

According to the third aspect of the present invention, since the height of the pillow can be adjusted by inflating and contracting the airbag, the pillow can be used according to the user's preference and the usability is improved.

Further, when the airbag is inflated, a gap is formed between the air permeable foam and the main body of the low resilience foam, and heat can be smoothly discharged to the outside from the gap. For this reason, heat release becomes good, and use without stuffiness becomes possible.

According to the fourth aspect of the present invention, since the gas permeable foam is supported by being sandwiched between the main bodies of the low resilience foam, the gas permeable foam is not crushed and the gas permeability can be maintained.
It can be used without stuffiness.

According to the fifth aspect of the present invention, since the breathable foam comes into contact with the user's head, the heat of the head can be immediately radiated, and the stuffiness can be prevented.

[0019]

1 and 2 show a pillow 1 according to an embodiment of the present invention. As shown in FIG. 1, the pillow 1 has a head supporting portion 2 for supporting a user's head 10 (see FIG. 2).
And a neck support portion 3 that supports a neck (not shown). The neck support part 3 is the head support part 2
The head 10 is low and the neck is high when the pillow 1 is used. As a result, the cervical vertebra is in a state of a natural curve, so that no burden is applied to the cervical vertebra.

FIG. 2 shows the internal structure of the pillow 1, in which a core layer 4, a breathable foam layer 5, and a support layer 6 as a "body" are shown.
Are laminated in order from the bottom, and the laminate 7 is provided inside the skin portion 8 on the outer surface side. The laminated core material layer 4, air-permeable foam layer 5, and support layer 6 are fixed to each other by adhesion, welding, or the like.

For the core layer 4 of the laminate 7, urethane foam having high density and high hardness is used. The core material layer 4 having a large hardness has a small compression amount, and does not settle even when the weight of the user's head 10 acts. For this reason, since the whole pillow 1 is not deformed, the head 10 can be reliably supported.

For the breathable foam layer 5, urethane foam made of a continuous foam is used. The continuous foam has an open cell structure, and has good air permeability because heat can flow inside. Therefore, heat can be released to the outside, and heat is prevented from being trapped inside the pillow 1. For this reason, use with a cool feeling without stuffiness becomes possible.

As shown in FIG. 1, the air-permeable foam layer 5 is located from the head supporting portion 2 to the neck supporting portion 3, so that heat from not only the head 10 but also a wide range of parts including the neck can be absorbed. It is possible to release.

Because of these properties, as the breathable foam layer 5, for example, a continuous foam having a low density of 30 kg / m ² and 10 cells / 25 mm can be used.

The support layer 6 is disposed on the neck support portion 3 as shown in FIG. 1, and acts so that the neck support portion 3 is raised. For this support layer 6, a low resilience urethane foam is used. The low-rebound urethane foam has a soft feeling and a good hardness, so that the head 10 can be reliably supported without sagging.

The skin portion 8 is wound around the outer periphery of a laminated body 7 composed of the core material layer 4, the breathable foam layer 5, and the support layer 6, and a portion in contact with the laminated body 7 is bonded, welded, or the like. Thereby, it is integrated with the laminate 7. The skin portion 8 is wound so as to cover the entire head supporting portion 2 and the neck supporting portion 3 to prevent the laminate 7 from coming into contact with the head.

The skin portion 8 has a thickness of about 10 mm, and is made of the same low-resilience urethane foam as that of the support layer 6. Therefore, the skin portion 8 itself also has hardness, and does not sag. In addition, since the user contacts the head 10 in a soft state, a soft feeling of use can be given to the user, and usability is improved.

Such a skin portion 8 is not wrapped around the left and right end surfaces of the laminate 7, and therefore, as shown in FIG. 1, both end surfaces of the laminate 7 are exposed. Thereby, both end surfaces of the breathable foam layer 5 are also exposed, and heat (indicated by an arrow in FIG. 2) can be released to the outside from the exposed both end surfaces. Therefore, it is possible to effectively prevent the heat from being trapped inside.

In this embodiment, the breathable foam layer 5 is laminated below the support layer 6 and the skin portion 8 at the neck support portion 3 and is laminated below the display portion 8 at the head support portion 2. I have. In addition, the support layer 6 and the skin portion 8 are made of a low-resilience urethane foam having hardness. Therefore, since the weight of the head 10 is received by the support layer 6 and the skin portion 8, it does not directly act on the breathable foam layer 5, and the breathable foam 5 does not collapse.
Thereby, the air permeability of the air permeable foam layer 5 can be reliably ensured, and the use with a refreshing feeling without stuffiness can be performed.

As shown in FIG. 2, a through-hole 11 is formed in the air-permeable foam layer 5 in the thickness direction, and an inflatable airbag 9 is disposed in the through-hole 11.
The airbag 9 has a valve, not shown, and is inflated by blowing air from the valve. Since the height of the pillow 1 can be changed by this expansion, it is possible to adjust the height to a user's preference.

In the state where the airbag 9 is inflated, between the breathable foam layer 5 and the support layer 6, between the breathable foam layer 5 and the skin portion 8, and further between the breathable foam layer 5 and the core material. A gap is generated between the layer 4 and the layer 4. These gaps act as channels for releasing heat (see arrows in FIG. 2).
Therefore, heat dissipation can be promoted, and use without stuffiness can be performed more reliably.

In such an embodiment, the pillow 1 is manufactured by forming the laminated body 7 by performing lamination and winding the skin portion 8 around the laminated body 7. Accordingly, the pillow 1 has a simple structure, can be easily manufactured, and is inexpensive.

Further, since the breathable foam layer 5 is laminated on the support layer 6 and the skin portion 8, heat can be continuously dissipated. For this reason, maintenance becomes unnecessary and it becomes convenient in use.

Further, as the low resilience urethane foam used for the support layer 6 and the skin portion 8, a slab urethane foam can be used, and thus, it can be manufactured at a low cost.

FIG. 3 shows another embodiment of the present invention. In this embodiment, a laminate 15 is formed by laminating the intermediate layer 12 and the upper layer 13 on the core material layer 4,
The skin portion 14 is wound around the laminate 15. The middle layer 12 and the upper layer 13 are made of low-resilience urethane foam, so that the entire pillow 16 is prevented from sagging and a predetermined height is maintained.

For the skin portion 14, a continuous foam similar to the breathable foam layer 5 in FIG. 2 is used. This skin 1
Reference numeral 4 is located on the outer portion of the pillow 16, and directly contacts the head and neck of the user. Then, the skin portion 14 allows the heat of the head and neck to be released by the contact, so that a cool use is possible. Although not shown, the airbag can be provided inside the laminate 15 also in the embodiment of FIG. 3, whereby the height of the pillow 16 can be easily adjusted.
