Abstract

To implement a comfortable sleeping feeling/sleep by making sweat and the like from a human body be absorbed and diffused and making humidity be not felt.SOLUTION: Water absorbed in a first layer is sent to an end edge of a futon through vent holes 8 of a second layer 3 and is discharged to the outside, which implements a comfortable sleep without feeling humidity. Water such as sweat from a human body is absorbed by the first layer but moves quickly to the second layer 3, which inhibits humidity from being felt at the first layer. This is because water having moved to the second layer 3 reaches an end edge of the second layer 3 through the vent holes 8 in the second layer 3 and is quickly discharged. A third layer has an antibacterial property and prevents mold and various bacteria from being reproduced by water and humidity having reached the second layer 3.SELECTED DRAWING: Figure 5

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a futon that does not feel moisture, is comfortable, and is comfortable to sleep.

In order to achieve the above object, the futon of the present invention is a first layer that comes into contact with a human body and absorbs moisture such as sweat from the human body, and has higher water absorption and flexibility than the following second layer. The layer has a porosity of 10% or more, even though the first layer and the constituent materials provided under the first layer are substantially connected from one edge of the layer to the other edge. A large number of vent holes are formed that penetrate from one edge to the other and are exposed at both ends, which allows air and moisture to easily pass through and is highly breathable, and is absorbed by the first layer. A flexible second layer that releases the moisture to the outside of the duvet to keep the first layer dry, and below the second layer, in the second layer, and above the second layer.

(1) Structure of Futon 1 FIG. 1 shows the upper surface / plane of the futon 1 of the present invention, FIG. 2 shows the lower surface / bottom surface of the futon 1 of the present invention, and FIGS. 3 and 4 show a cross section of the futon 1 of the present invention. The cross-sectional direction of FIG. 3 and the cross-sectional direction of FIG. 4 are orthogonal to each other, and FIG. 5 shows the enlarged end face of the second layer 3.

Futon 1 is a futon that is laid under the sleeping human body, and is laid on tatami mats, beds, mattresses, and other flat places, all of which are flexible from top to bottom. The second layer 3 and the third layer 4 are provided and laminated. The first layer 2 is in contact with the human body, absorbs moisture such as sweat from the human body, and is excellent in sweat absorption, quick drying, antibacterial, deodorant, elasticity, cushioning, etc., and is more water-absorbent than the second layer 3 above. Is high.

The upper surface cloth 5 on the upper surface of the first layer 2 is, for example, 25 to 50% for Aqua Job (a product of Asahi Kasei Corporation), 25 to 50% for Shine Up (a product of Kuraray Co., Ltd.), and 10 to 40% of regular yarn, in total. It is knitted by blending, blending, blending, or mixing within a range not exceeding 100%. Aquajob is excellent in sweat absorption and quick-drying, does not feel moisture, and Shine-up is photocatalytic, and is excellent in antibacterial and deodorant.

About 100% polyester is contained between the first partition cloth 6 on the lower surface of the first layer 2 and the upper surface cloth 5. This polyester has elasticity and cushioning properties, and also has hygroscopicity and water absorption. The first partition cloth 6 may have the same composition and structure as the top cloth 5, but only the shine-up may be omitted.

The top cloth 5 exerts antibacterial and deodorant effects, and if the futon 1 is left unfolded after waking up, it is exposed to light and exerts deodorant, deodorant, antibacterial, and bactericidal effects. This effect becomes remarkable on the bed, and the effect is exhibited even on other tatami mats if the futon 1 is kept spread.

In addition, the effect is exerted by shining light on the part that is not in the shadow of the human body even during sleep, and if the human body moves by turning over, the place where the light shines changes, and the effect is exerted on the futon 1 and the upper surface cloth 5 as a whole. It will be demonstrated. The amount of light that can exert the photocatalyst may be small enough not to interfere with sleep.

As shown in FIGS. 3 and 4, the first partition cloth 6 on the lower surface of the first layer 2 is separated from the second layer 3, and the first partition cloth 6 and the upper surface cloth 5 are sewn together and quilted. It has been processed. The quilting 10s are equidistant to each other and orthogonal to each other, and each interval is several cm.

By this quilting process, unevenness is formed on the surface of the first layer 2, that is, the surface of the futon 1, and the unevenness increases the gap between the human body and the futon 1, improves the air permeability, and feels moisture. However, the above-mentioned deodorant, deodorant, antibacterial, and bactericidal effects are promoted.

A second partition cloth 7 is provided under the first partition cloth 6, and the second layer 3 is provided and sandwiched between the first partition cloth 6 and the second partition cloth 7. .. The second layer 3 is provided below the first layer 2, and is composed of, for example, Mumac (a product of Achilles Corporation).

This Mumac is a non-membrane foam material, for example, a non-membrane urethane foam that removes the film-like film in the bubbles of the urethane foam to make it easier for air and water to pass through. It becomes difficult, has excellent breathability, does not feel moisture, has 10 to 100 times the breathability of urethane foam with a normal film, does not feel moisture, and can be washed with water.

In this mumac, the material 13 of the urethane foam constituting the mumac is substantially connected from one edge of the layer to the other edge, and the mumac as a whole is not easily separated and integrated. This mumac has a porosity of 10% or more and a large number of ventilation holes 8 are formed, and the ventilation holes 8 penetrate from one edge of the layer to another and are exposed at both ends. ..

As shown in FIG. 5, this makes it easy for air and moisture to pass through and has high air permeability even though the material 13 is substantially connected from the edge having a large number of ventilation holes 8 to the other edge. Through the ventilation holes 8, the moisture absorbed by the first layer 2 is discharged to the outside of the futon 1, the first layer 2 is kept in a dry state, and no moisture is felt. Since FIG. 5 is an end view, the material 13 does not seem to be connected from one edge to the other, but in reality, the material 13 bypasses the vent 8 on the upper or lower side of the paper in FIG. It is connected.

Since the second layer 3 is made of urethane foam or the like and has foamability, the porosity becomes high and the porosity becomes 10% or more. However, despite the foamability, a large number of the ventilation holes 8 are formed. Therefore, there is no film that blocks the air permeability, and the air permeability is maintained.

Due to such a structure, the first layer 2 has higher water absorption and hygroscopicity than the second layer 3, and the first layer 2 absorbs sweat from the human body well, but the first layer 2 has a quick-drying property. Therefore, this absorbed sweat etc. is transferred from the first layer 2 to the second layer 3, and is immediately released by the second layer 3, so that the first layer 2 is not dry and sticky and feels damp. You can achieve a comfortable sleep.

The porosity indicates the ratio of the volume occupied by the material 13 or the ratio of air per unit volume, and is substantially proportional to the degree of foaming. As the degree of foaming increases, the ratio of voids increases and the air permeability also increases. As the degree of foaming decreases, the proportion of voids decreases and the air permeability decreases.

The second partition cloth 7 is the same as the first partition cloth 6, but may be different. The first partition cloth 6 and the second partition cloth 7 are excellent in breathability and water permeability, and do not feel moisture. In some cases, the first partition cloth 6 or the second partition cloth 7 may have sweat absorption, quick drying, antibacterial, deodorant, elasticity, cushioning property, and photocatalytic effect.

A lower surface cloth 9 is provided under the second partition cloth 7, and the third layer 4 is provided and sandwiched between the second partition cloth 7 and the lower surface cloth 9. The third layer 4 is provided under the second layer 3, and is composed of, for example, a bamboo pile (a product of Bruneez Co., Ltd. and Toa Textile Co., Ltd.).

This bamboo pile has fibers formed in a pile shape, has antibacterial properties, is absorbed by the first layer 2 and reaches the second layer 3, and prevents the growth of mold, microorganisms, germs, and fungi due to moisture and humidity. I'm out. In some cases, this bamboo pile has a quick-drying effect, a cooling effect due to the heat of vaporization, and an ultraviolet ray blocking effect. In some cases, the third layer 4 may be formed in the second layer 3, between the first layer 2 and the second layer 3, in the first layer 2, on the first layer 2, and the like. good.

As shown in FIGS. 3 and 4, the second partition cloth 7 and the lower surface cloth 9 are sewn together and quilted. The quilting 11s are equidistant to each other and orthogonal to each other, and each interval is several cm. By this quilting process, unevenness is formed on the third layer 4, that is, the lower surface of the futon 1, and the unevenness increases the gap between the futon 1 and the surface on which the futon 1 is placed to increase the air permeability. It gets better, does not feel moisture, and promotes the above-mentioned deodorant, deodorant, antibacterial, and bactericidal effects.

The second layer 3 has elasticity and cushioning property, and is more than a predetermined ratio, for example, 25, with respect to a predetermined pressure due to the weight of the human body, for example, 100 kg / 30 cm × 170 cm = 100 kg / 5100 cm2 = 19.6 g / cm2. It is not compressed by% or more, and the ventilation hole 8 is not deformed by 25% or more. As a result, air permeability is maintained from the edge of the second layer 3 having the vent 8 to the other edge, and the vent 8 is exposed at both end edges, so that the release of moisture and moisture is maintained. And do not feel damp.

The above 100 kg / 30 cm × 170 cm has a relatively large human body, but is 5 g / cm2, 10 g / cm2, 15 g / cm2, 20 g / cm2, 25 g / cm2, 30 g / cm2, 35 g / cm2, 40 g / cm2. On the other hand, it does not have to be compressed by 25% or more. Of course, at 20 g / cm2 or less, it is not compressed by 25% or more.

This compression ratio may not be compressed by 30% or more, may not be compressed by 35% or more, may not be compressed by 40% or more, may not be compressed by 50% or more, or 60. It may not be compressed by% or more, it may not be compressed by 70% or more, it may not be compressed by 80% or more, it may not be compressed by 90% or more, or it may not be compressed by 20% or more. It may be compressed by 15% or more, may not be compressed by 10% or more, or may not be compressed by 5% or more.

As shown in FIGS. 1 and 2, the quilting 10 of the upper surface cloth 5 is formed parallel to the upper edge, the lower edge, and the side edge of the futon 1, and the quilting 11 of the lower surface cloth 9 is the quilting 11 of the futon 1. It is formed at an angle of 45 degrees with the upper edge, lower edge, and side edge. Therefore, as shown in FIGS. 3 and 4, the concave of the first layer 2 and the concave of the third layer 4 and the convex of the first layer 2 and the convex of the third layer 4 do not correspond to each other by 90% or more. The deviation is 90% or more, and the unevenness is not formed on the second layer 3.

As a result, the concave of the first layer 2 and the concave of the third layer 4, the convex of the first layer 2 and the convex of the third layer 4 hardly overlap, and the unevenness of the entire futon 1 does not become large, and the futon 1 does not give a sense of discomfort to the human body, and does not give a sense of discomfort to the human body even when turning over, and the sleep of the human body becomes comfortable.

The lower surface cloth 9 may be provided with a photocatalyst. As a result, even if the futon 1 is turned upside down and used upside down, the deodorant and antibacterial effects of the light can be exhibited. Even when the futon 1 is used as a comforter instead of a mattress, the effect of the photocatalyst can be achieved regardless of whether the first layer 2 is on the top or the third layer 4 is on the top.

The thickness of the second layer 3 is thicker than the thickness of the first layer 2 or the thickness of the third layer 4. As a result, the ventilation holes 8 are less likely to be closed, air permeability is maintained from the edge of the second layer 3 having the ventilation holes 8 to the other edges, and the ventilation holes 8 are exposed at both end edges. The above-mentioned moisture and moisture release are maintained, and no moisture is felt.

The first layer 2 may be thicker than the second layer 3 or the third layer 4 or may have the same thickness, and the second layer 3 may be thicker than the first layer 2 or the third layer 4 and may be the same. The thickness may be the same, the third layer 4 may be thicker than the second layer 3 or the first layer 2, or the same thickness may be used. As for the side surface of the futon 1, the side surface of the second layer 3 is exposed.

However, the side surface of the duvet 1 may be covered with an elongated ring by a thin cloth 12 having a breathability such as a thin see-through. The upper edge of the thin cloth 12, the peripheral edge of the upper surface cloth 5, and the peripheral edge of the first partition cloth 6 are sewn with a bias tape and subjected to bias processing, and the seam allowance is processed such as finishing and edging. Has been done.

Similarly, the lower edge of the thin cloth 12, the peripheral edge of the lower surface cloth 9, and the peripheral edge of the second partition cloth 7 are sewn with a bias tape interposed therebetween to be biased. It has been processed. The peripheral edge of the first partition cloth 6 or the second partition cloth 7 is sewn with another bias tape separated from the bias tape, and is subjected to bias processing. May be done.

The degrees may be the same without deviation, and the quilting 10 and the quilting 11 may be exactly the same.

Even if the quilting direction of the quilting 10 and the quilting 11 is the same, the quilting line is deviated by 50%, 40%, 30%, 25%, 20%, 15%, 10%, or 5% of the quilting width. Well, it is 0%, and it may be the same without deviation.

The width of the quilting of quilting 10 and the width of quilting of quilting 11 were the same, but they may be different, and the quilting line may be a curve other than a straight line, or three other than two intersecting lines. In addition to squares, the quilting squares are square, rectangular, square, triangular, hexagonal, disk, elliptical, polygonal, trapezoidal, semi-elliptical, parallelogram. , Diamond, Polygon, Triangle, Trapezoid, Ring, Semi-Ring, Star, Fan, Curve, Cross, L-shaped, H-shaped, I-shaped, U-shaped, T-shaped, C-shaped, O-shaped, N-shaped, It may be M-shaped, X-shaped, J-shaped, Y-shaped, E-shaped, F-shaped, S-shaped, or V-shaped.

The quilting may also be formed in the second layer 3, the second layer 3 has two or more sheets, the second layer 3 of the uppermost layer has the same quilting as the first layer 2, and the same quilting as the first layer 2 is performed. The lower second layer 3 may be quilted in the same manner as the quilting 11 in the third layer 4.

The second layer 3 has elasticity and cushioning properties, is not compressed by 25% or more with respect to a predetermined pressure due to the load of the human body, is not deformed by 25% or more, and is not deformed by 25% or more. Breathability is maintained from one edge to the other, but the compressibility is 20% or higher, 15% or higher, 10% or higher, 5% or higher, 1% or higher, 30% or higher, 35% or higher, 40. % Or more, 45% or more, 50% or more, 55% or more, 60% or more, 65% or more, 70% or more, 75% or more, 80% or more, 85% or more, 90% or more, 95% or more, 99% or more It may be.

The vertical and horizontal dimensions of the first layer 2, the second layer 3, and the third layer 4 are the same, but may be different, and any of them may be larger or smaller. The third layer 4 may be made of another material as long as it has antibacterial properties. The first layer 2 may be made of another material as long as it can absorb water such as sweat from the human body.

The second layer 3 penetrates from one edge of the second layer 3 to the other edge even though the constituent material is substantially connected from one edge of the second layer 3 to the other edge. As long as a large number of exposed ventilation holes 8 are formed on both end edges, the material may be made of another material.

In short, it suffices that air and moisture can easily pass through and the air permeability is high, and the moisture absorbed in the first layer can be released to the outside of the futon to keep the first layer 2 in a dry state. It is not necessary that all of the ventilation holes 8 reach the edge of the futon 1, and a part of the ventilation holes 8 does not have to reach the edge of the futon 1.

The ventilation hole 8 is not limited to a straight line, but may be bent in a zigzag manner, may be branched or merged, and the connecting edge is not only the left and right edges of the second layer 3 but also the upper edge. It may be an edge, a lower edge, a leading edge, a trailing edge, or a flat surface or a bottom surface of the second layer 3.

The thicknesses of the first layer 2, the second layer 3, and the third layer 4 were substantially uniform over the entire surface, but may be different. For example, it may become thicker from the center toward both side edges, the upper edge or the lower edge. As a result, the number of ventilation holes 8 exposed on the edge is increased, and the air permeability is improved. Of course, conversely, it may become thinner toward both side edges, upper edge or lower edge, and the planes or bottom surfaces of the first layer 2, the second layer 3, and the third layer 4 may be parallel to each other and flat. However, it may be uneven.

Since the first layer 2 has higher water absorption than the second layer 3, the water absorption of the first layer 2 is high and the absorbed water such as sweat does not return to the human body, and it is dry, non-greasy and comfortable. Achieve a comfortable sleep. Even if the second layer 3 has a lower water absorption than the first layer 2, the water is released through the ventilation holes 8, so that the water in the first layer 2 easily moves to the second layer 3.

Of course, the water absorption of the first layer 2 may be lower than that of the second layer 3, and the water absorption of the first layer 2 and the water absorption of the second layer 3 may be substantially the same. The third layer 4 may have lower water absorption than the first layer 2 or the second layer 3, and the water absorption of the third layer 4 is the water absorption of the first layer 2 or the water absorption of the second layer 3. May be about the same.

All the materials 13 of the second layer 3 need not be connected from one edge to another, and may not be partially connected from the edge to another edge. All of the other materials of the first layer 2 or the third layer 4 need not be connected from one edge to another, and may not be partially connected from the edge to another edge. ..

[6] The futon according to claim 5, wherein the thickness of the second layer is thicker than the thickness of the first layer or the thickness of the third layer. As a result, the ventilation holes are less likely to be closed, air permeability is maintained from the edge of the second layer having the ventilation holes to the other edge, and the ventilation holes are exposed at both end edges, and the moisture content. , Moisture release is maintained and does not feel moisture.

Sweat from the human body is absorbed and released, and you can realize comfortable sleeping and sleeping without feeling moisture. Moisture absorbed in the first layer is sent to the edge of the futon through the ventilation holes in the second layer and released to the outside, realizing a comfortable sleep without feeling moisture. Moisture such as sweat from the human body is absorbed by the first layer 2, but immediately moves to the second layer 3, and the first layer 2 does not feel moisture. This is because the water transferred to the second layer 3 reaches the edge of the second layer 3 through the ventilation holes 8 in the second layer 3 and is immediately released. The third layer 4 has antibacterial properties and prevents the growth of mold and germs due to moisture and humidity that have reached the second layer 3.
