Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to bedding items such as comforters, mattresses, pillows and cushions.

[0002]

2. Description of the Related Art It is generally said that humans perspire 2 to 3 liters of sleep when they go to bed overnight, and it is common to experience sweating from the head to the upper body when getting up in the morning. Is. This sweat is absorbed by the bedding and comforter through pajamas. The mattress is made of cotton that is a little harder than the comforter because it prevents the elasticity of the person from falling asleep and the physical shape of the human body such as the spine while sleeping. I used cotton.

As described above, since the mattress is generally compressed, it has almost no air permeability. Therefore, moisture such as sweat that has been once absorbed is easily absorbed by the bedding, and the sweat absorbed by the bedding has a structure that is extremely difficult to evaporate. Also, the comforter is not compressed as compared with the mattress, but has a structure that is not very breathable.

Therefore, as a structure for making a mattress or a comforter breathable, there has already been provided a batting as a core material of the mattress or a comforter, which is provided with a vertically penetrating hole. As a conventional example in which a hole is formed in a batting, for example, JP-A-63-158090 and JP-A-8-19 can be used.
6392 and Japanese Utility Model Laid-Open No. 55-120400.

According to the technique disclosed in the above-mentioned Japanese Patent Laid-Open No. 63-158,099, a large number of wood piece accommodating holes are bored in a foam layer made of polyurethane as a core material, and wood particles are substantially filled in the wood piece accommodating holes. It's a full bottle. With this structure, the scent of wood makes the user comfortable, and
It is said that it has excellent hygroscopicity and moisture release when dried,
Furthermore, so-called fatigue is reduced. Further, in JP-A-8-196392 mentioned above, a hole is formed in a row around a polyurethane foam and a core in which polyethylene foam is laminated on the upper and lower surfaces of the polyurethane foam, so that the weight around the core is reduced. And trying to get breathable.

Further, in Japanese Utility Model Laid-Open No. 55-120400, a large number of through holes are bored in the outer cotton laminated on the upper surface or the upper and lower surfaces of the core cotton, and these through holes function as heat retaining holes and ventilation holes. It has an effect to facilitate the drying of absorbed water.

[0007]

However, such a conventional example has the following problems. That is, in Japanese Patent Laid-Open No. 63-158,093, since a large number of wood pieces are put in the through-holes formed in the foam layer, the heat insulation and the air permeability are inevitably deteriorated, and the wood is not suitable for use as a mattress. Although suitable, it is unsuitable for comforters.

Further, in Japanese Unexamined Patent Publication No. 8-196392, the holes are formed only around the core, so that there is a problem that the heat retention and air permeability of the whole core are very poor. In addition, the hole is formed by penetrating the polyurethane foam and the polyethylene foam laminated on the upper and lower surfaces of this polyurethane foam at the same position. Therefore, the air in the hole easily flows to the outside and keeps the heat retention. There is a problem of chipping.

Further, in Japanese Utility Model Laid-Open No. 55-120400, in the case of a two-layer structure of an outer cotton having a through hole and a core cotton, it has a function of heat retention and air permeability. Since the through-hole has only one layer, there is a problem in that it lacks heat retention and air permeability. In addition, when the outer cotton with through holes is laminated on the upper and lower surfaces of the core cotton, it has a three-layer structure of one core cotton and two outer cotton, and has a structure for providing heat retention and breathability. However, there is a problem in that the cost becomes high at the same time as it becomes complicated. In particular, a two-layer structure of one core cotton and an outer cotton with one through hole punched, and a three-layer structure with one core cotton and two outer cotton with a through hole punched When the mattress is the same, the vertical dimension of the through-hole is shortened by the thickness of the core cotton without through-holes, and heat insulation and air permeability are reduced accordingly. That is a fatal problem for the mattress.

The present invention has been provided in view of the above-mentioned problems, and is excellent in heat retention and breathability due to its simple structure and can be applied to bedding, comforters, pillows, cushions and bed pads. It is intended to provide bedding.

BEST MODE FOR CARRYING OUT THE INVENTION (First Embodiment) A first embodiment of the present invention will be described in detail below with reference to the drawings. In the first embodiment, the configuration of the comforter will be described with reference to FIGS. FIG. 4 shows a plan view of the comforter 1, and FIG. 5 shows a cross-sectional view of the comforter 1. The comforter 1 includes two sheet-shaped core members 2a and 2b and two middle members 4a arranged on the upper and lower surfaces of the core members 2a and 2b.
4b and a side material 6 made of cloth for covering the core materials 2a and 2b and the intermediate materials 4a and 4b. The two core materials 2a and 2b and the two inner materials 4a and 4b constitute a batting body 5.

Core materials 2a, 2b constituting the comforter 1
Uses a so-called solid cotton consisting of 100% polyester cotton, and its thickness is, for example, 100 mm. Further, the core materials 2a and 2b are provided with a large number of through holes 3 having a diameter of about 20 mm and penetrating vertically, for example, about 100 holes per 1 m ² are provided. The shape of these through holes 3 is cylindrical.

Here, as shown in FIGS. 2 and 3, the positions of the through holes 3 of the upper and lower core members 2a, 2b are opened so that the upper and lower through holes 3 do not communicate with each other. The lower surface of the through hole 3 formed in the upper core material 2a is located on the upper surface of the lower core material 2b and is closed. Similarly, the upper surface of the through hole 3 formed in the lower core material 2b is
It is in a state of being closed by the lower surface of the upper core material 2b.
The positions of the through holes 3 in the upper and lower core members 2a and 2b may be arranged so that the other through hole 3 is located at the central portion of the four surrounding through holes 3 as shown in FIG. It is only necessary to shift the positions of the upper and lower through holes 3 so that they do not overlap.

The middle materials 4a, 4b are so-called soft cotton made of 100% polyester cotton, and the thickness thereof is about 50 mm. The above-mentioned two laminated core materials 2a and 2b are wound with the above-mentioned inner materials 4a and 4b, and when the user touches or touches the body with these inner materials 4a and 4b, a fit or softness is obtained. I try to give a feeling. The two core materials 2a and 2b may be wound with one medium material. Further, the middle material 4a is arranged on the upper surface of the through hole 3 of the upper core material 2a, and the through hole 3 of the lower core material 2b.
Since the middle material 4b is located on the lower surface of the
The inflow and outflow of air into the through holes 3 of a and 2b are prevented.

The bag-shaped side material 6 for covering the batting body 5 composed of the core materials 2a, 2b and the inner materials 4a, 4b is formed of a cloth made of 100% of polyester fiber. It has undergone anti-fusion processing. As a manufacturing method for applying the anti-fusing process to the side material 6, for example, a manufacturing method described in Japanese Patent Publication No. Sho 49-32760, a cloth called Boumilan (registered trademark) of Sakai Obex Co., Ltd., or Komatsu Seiren Co., Ltd. It uses a fabric called Levan-Extra® of the company. Of course, when the anti-fusing process is applied, it is not limited to these manufacturing methods and fabrics,
It is also possible to use the anti-melting fabric provided by various companies, or to apply the anti-melting treatment to the fabric by using a commercially available anti-melting agent.

By the way, until now, the core materials 2a, 2 of the present invention have been used.
There was no idea to use the solid cotton used in b) for the comforter instead of the mattress. In other words, the quilt is, as is well known, hung on a person sleeping on the quilt, and therefore, the quilt itself must be supple and fit to the body. At the same time, comforters and beddings used for business purposes such as hotels and hospitals must not suffer from so-called setback after being washed many times. Moreover, the comforter and the mattress are required to have heat retention and breathability, and it is necessary to efficiently absorb perspiration from the body and to easily dry the sweat.

Therefore, in the present invention, the core members 2a, 2b forming the comforter 1 are formed with a large number of through holes 3 by using the cotton wool which is conventionally used for the quilt, so that the core member 2a, 2b was softened so as to give a fit as if cotton was used. Further, the positions of the through holes 3 formed in the upper and lower core members 2a and 2b are displaced so as not to overlap each other, and the middle member 4 is placed on the upper and lower surfaces of the core members 2a and 2b.
By laminating a and 4b, the through holes 3 of the core materials 2a and 2b are closed. Therefore, the air in the through holes 3 is less likely to flow out to the outside, the heat retaining property is improved, the heat transfer with the outside is easily blocked, and the winter is warm like a duvet and the sleeping is comfortable in the summer. You can

Further, even when sweating, between the air in the through hole 3 and the fibers of the core materials 2a, 2b and the intermediate materials 4a, 4b, and between the air in the through hole 3 and the outside. Has better air permeability and is easier to dry. Further, since the shape of the through-hole 3 is cylindrical, more air in the through-hole 3 can be contained, the heat retaining property is further enhanced, and the through-hole 3 is not formed into a rectangular shape, but is a cylinder. By making it into a shape, it is possible to further soften the sheet-like core materials 2a and 2b of the solid cotton, and to ensure the fitting property to the body. The cross-sectional shape of the through hole 3 may be a triangle, a quadrangle, or a polygon. However, the shape of the through hole 3 is preferably cylindrical (having a circular cross section) for the reasons described above.

Further, since the side material 6 which is the surface of the comforter 1 is subjected to the anti-fusing process, it is possible to prevent the fire caused by the sleeping cigarette. In particular, in hotels and the like, many people smoke a cigarette, and it is possible to prevent a fire caused by a cigarette, which is the main cause of the fire. Further, although the cost is high if the side material 6 is made of a fabric subjected to flameproofing, the antifusible fabric is generally inexpensive and easy to purchase. Furthermore, since the side fabric 6 has been subjected to anti-fusing processing, it has a very good texture and fit compared to other fabrics, and has the functions of absorbing water, absorbing moisture, and suppressing electricity. is there.

Further, the core material 2 which constitutes the comforter 1
Since cotton is used for a and 2b, even when it is used for commercial use in a hotel or a hospital, it is possible to eliminate fatigue and increase the restoring force of the comforter 1 itself. it can. Therefore, the comforter 1 lasts a long time and can be comfortably used forever. Furthermore, the core materials 2a and 2b and the middle material 4 which form the comforter 1
Polyester 100 is used for all materials of a, 4b and side material 6.
%, All of them can be recycled in the same treatment step, and can be easily recycled, so that the bedding 1, which is eco-friendly, can be obtained.

Here, in the above embodiment, the core members 2a, 2
Although b has two layers, it may have three or more layers. In this case, the positions of the through holes 3 drilled in the core material of each layer are shifted so that they do not overlap. Also,
Although the thickness of the core materials 2a and 2b was 100 mm,
You may make it use in the range of mm-150 mm. Similarly, the thickness of the intermediate members 4a and 4b was set to 50 mm, but 2
The thickness may be in the range of 0 mm to 80 mm. That is, as long as the thickness of the comforter 1 does not become thicker than necessary, the thickness of each core material 2a, 2b, the middle material 4a, 4b,
The number of layers of the core materials 2a and 2b may be set appropriately.

In FIG. 4, the batting body 5 is attached to the side material 6
After being stored in, or after covering the batting main body 5 with the upper and lower linings or the outer material, the periphery is sewn with thread, and quilting sewing is performed in a lattice pattern so that the batting main body 5 is not biased.

Here, the cotton wool of the core materials 2a and 2b is softened by appropriately setting the number and size of the through holes 3 of the core materials 2a and 2b. The number of the through holes 3 was 100 per 1 m ² and the diameter was 20 mm. However, this is an example, and in order to obtain appropriate softness and hardness, the number and diameter of the through holes 3 may be appropriately changed. Needless to say.

In the present invention, the soft cotton used as the core materials 2a and 2b may be softened by changing the mixing ratio of the cotton hardened by heat. That is, for example, 100% of polyester cotton having a melting point of 100 ° C., for example, the lower melting point raw material of 100% polyester cotton having a melting point of 50 ° C. becomes more solid, and the mixing of the low melting point raw material is reduced. It has been found that the softer the cotton used for the core materials 2a and 2b of the comforter 1 is made, the texture and fit of the comforter 1 are obtained by changing the mixing ratio. . Also in this case, similarly to the above, from the viewpoint of heat retention and air permeability, a large number of through holes 3 are formed at different positions from each other.

In the comforter 1 of this embodiment, it is necessary to make it soft because of its suppleness and fit when worn on a person. Therefore, the ratio of the low melting point raw material to the polyester cotton forming the core materials 2a and 2b is set to 15 to 20 when the whole is set to 100. As a result, the core materials 2a and 2b can be softened and texture and fit can be obtained despite using the cotton wool. In addition, the core material 2 as the comforter 1
The densities of a and 2b are in the range of 10 to ³⁰ kg / m ³ .

(Second Embodiment) FIGS. 7 to 9 show a second embodiment, which is a bedding 1 as a bedclothing.
0 is shown. It should be noted that elements having the same functions as those of the previous embodiment will be described with the same numbers.

The structure of the mattress 10 is basically the same as that of the comforter 1, and the thickness is slightly different in size. This mattress 10 includes two core materials 2a, 2
b, two core members 4a and 4b arranged on the upper and lower surfaces of the core members 2a and 2b, and a side material 6 covering the core members 2a and 4b. The two layers of core materials 2a, 2b are also provided with a large number of through holes 3 as in the previous embodiment, and the through holes 3 of the upper and lower core materials 2a, 2b do not overlap as shown in FIG. The position is shifted. Further, the thickness of the core materials 2a and 2b is smaller than that of the comforter 1, and, for example, each is 50
The thickness is mm. The number of layers of the core materials 2a and 2b may be three or more, and the thickness of one core material becomes thinner as the number of layers increases.

Unlike the quilt 1, the mattress 10 needs to be made harder than the quilt 1. Therefore, the number and size of the through holes 3 formed in the core members 2a and 2b are changed. The number of 3 is smaller than that of the comforter 1, and the diameter of the through hole 3 is also reduced.

For example, the number of through holes 3 of the core materials 2a and 2b of the mattress 10 is 50 per 1 m ² , and the diameter is 20.
mm or the number of through holes 3 per 1 m ^{2 is} 100
In the case of individual pieces, the diameter of the through hole 3 may be 10 mm. Further, the number of the through holes 3 may be 50 per 1 m ² , and the diameter of the through holes 3 may be 10 mm. Accordingly, since the core materials 2a and 2b can be provided with appropriate hardness, the mattress 10 does not adversely affect the body shape of a person.

Further, since the side material 6 of the mattress 10 is also subjected to the anti-melting process as in the previous embodiment, it is possible to prevent a fire on the sleeping cigarette. The mattress 10 in this embodiment basically has the same configuration as the comforter 1 described above, and therefore has the same effect as the embodiment described above.

Further, as in the previous embodiment, the core materials 2a, 2
By changing the mixing ratio of b, the core materials 2a and 2b may be made hard for the bedding. In the mattress 10 according to the present embodiment, it is necessary to provide a firmness that does not adversely affect the body shape even when a person sleeps. Therefore, it is necessary to increase the ratio of the low-melting-point raw material to the polyester cotton forming the core materials 2a and 2b as compared with the case of the comforter 1 as described above.
In the case of 0, the ratio of the low melting point raw material is 30 to 40
I am trying. Thereby, it is possible to impart appropriate hardness to the mattress 10 and not to adversely affect the body shape of the sleeping person. In addition, the density of the core materials 2a and 2b as the bedding 10 is in the range of 80 to 120 kg / m ³ . Of course, a large number of through holes 3 are formed in the core materials 2a and 2b from the viewpoint of heat retention and air permeability.

(Third Embodiment) A third embodiment is shown in FIGS. In this embodiment, a cushion 20 is shown. Also in the case of the cushion 20 as in the previous embodiments, two core materials 2a and 2b, two middle materials 4a and 4b arranged on the upper and lower surfaces of the core materials 2a and 2b, and these are stored. A cushion 20 is formed by the side material 6 to be covered.

Since the cushion cushion 20 has the same hardness as that of the mattress 10 described above, the number and diameter of the through holes 3 formed in the core members 2a and 2b are set to be the core of the mattress 10 from the viewpoint of heat retention and air permeability. It is the same as the case of the materials 2a and 2b. Also,
The thickness of the core materials 2a and 2b of the cushion 20 is also about 50 mm. The thickness of the middle materials 4a, 4b is 1 comforter 1 or mattress 1
Although it is thinner than the case of 0, the same thickness may be used. By making the cushion 20 have the same hardness as that of the mattress 10 described above, it is possible to prevent sitting for a long time and fatigue of washing a large number of times. Similarly, the positions of the through holes 3 in the upper and lower core members 2a and 2b are also offset from each other so that they do not overlap. The number of layers of the core materials 2a and 2b may be three or more, and the thickness of one layer is reduced as the number of layers increases.

Since the side cloth 6 of the cushion 20 is subjected to the anti-fusing process as in the previous embodiments, it is possible to prevent fires from sleeping cigarettes and to obtain the same effects as in the previous embodiments. Is.
