Description

mattress

The present invention relates to a mattress.

Traditionally, mattresses used as bedding have good support (cushioning) to maintain a good posture to guide comfortable sleep, heat retention to cope with changes in body temperature during sleep, and maintain moderate humidity A great number of performances such as moisture permeability, moisture absorption and moisture release are required.

For example, Patent Document 1 describes a mattress that mainly includes a core part that becomes the core of the mattress and a surface layer part that covers the outer periphery of the core part. Since the core part of the mattress is provided with a coil spring or the like, the cushioning property can be enhanced and the body pressure supportability can be enhanced. Moreover, moisture permeability (breathability) can be improved by providing the core part with air holes communicating in the vertical direction and the width direction. Moreover, since the surface layer part mainly uses fibers, such as cotton, hygroscopicity and touch can be improved.

JP-A-8-224144 (see FIG. 1)

Here, when a relatively hard material such as a coil spring is provided on the core material portion, a relatively thick urethane material is used between the core material portion and the surface layer portion so that the human body does not feel a contact feeling such as a coil spring. It was necessary to provide a protective layer. However, since the urethane material is inferior in moisture permeability (breathability), sweat and moisture are not released to the outside, and there is a problem that moisture and moisture such as sweat tend to accumulate inside the mattress. Thus, accumulation of moisture and moisture such as sweat inside the mattress causes mold generation, and is particularly undesirable in a hot and humid climate because it promotes mold generation. Further, when the moisture permeability of the mattress is lowered, the back side of the human body is easily stuffed, so that there is a problem that the sleeping comfort is deteriorated and the sleep is disturbed.
On the other hand, when the coil spring and the communication hole are provided in the mattress, the structure design and manufacturing process of the mattress are complicated, the manufacturing work becomes complicated, and the degree of freedom in design is reduced.

Therefore, the present invention has been developed to solve such problems, and it is an object of the present invention to provide a mattress that can be manufactured relatively easily while improving moisture permeability and cushioning properties.

In order to solve the above-described problems, the present invention surrounds the surface layer portion, a core portion that has a plate shape, a surface layer portion that includes a plurality of fiber layers composed of fibers and covers the periphery of the core portion in layers. And an outer cover, wherein an average value of the outer diameters of the fibers constituting each of the fiber layers is formed so as to decrease as the distance from the core material portion increases. .

According to such a configuration, since the vicinity of the outer periphery of the core part is covered with the fiber layer made of fibers having a large outer diameter, the elasticity is relatively large, and even if a coil spring is provided in the core part. Can alleviate the feeling of contact with the human body. Further, since the gap between fibers having a large outer diameter becomes a relatively large space, moisture such as moisture and sweat tends to pass through the gap between fibers having a large outer diameter. Therefore, the moisture permeability is increased, and moisture can be prevented from accumulating inside the mattress. Moreover, since the circumference | surroundings of a core part are covered in a layer form with a fiber layer, body pressure support property and cushioning properties can be improved.

In addition, since the outer diameter of the fibers constituting each fiber layer decreases as the distance from the core portion increases, the human body side becomes a relatively soft layer, and the feeling of touch can be improved. Moreover, since the human body side is a relatively soft layer, body pressure dispersibility can be enhanced. In addition, since the mattress is manufactured by simply covering the periphery of the core portion with the fiber layer, it can be manufactured relatively easily, and the manufacturing cost can be reduced.

Moreover, it is preferable to use hair-like animal hair for the fibers used for the surface layer. According to such a configuration, it is possible to improve heat retention and moisture release. Moreover, since hair-like animal hair is comparatively hard, body pressure supportability can be improved more.

Further, it is preferable that a moisture absorption layer is formed between the core member and the surface layer. For example, the hygroscopicity of moisture such as moisture and sweat can be increased by forming the moisture absorbing layer using a material such as felt. Thereby, it is possible to prevent moisture such as moisture and sweat absorbed from the human body from flowing back to the human body.

According to the mattress according to the present invention, the moisture permeability and cushioning properties are enhanced, and the mattress can be manufactured relatively easily.

It is the partially broken perspective view which showed the mattress which concerns on this embodiment. FIG. 2 is a cross-sectional view taken along line X1-X1 in FIG. It is the expanded sectional view which showed A part of FIG. It is the enlarged view which showed animal hair. It is a schematic cross section which shows the state where the person slept on the mattress which concerns on this embodiment.

Next, embodiments of the present invention will be described in detail with reference to the drawings as appropriate. In the description of the present embodiment, the up, down, left, and right front and rear follow the arrows in FIG. Further, “outside” in the description refers to the outer cover 5 side with respect to the core member 2.

The mattress 1 according to the present embodiment is a thick rug laid under a mattress or on a bed as shown in FIGS. 1 and 2, and has a substantially rectangular parallelepiped shape. The mattress 1 includes a plate-shaped core member 2 provided at the center of the mattress 1, a moisture absorbing layer 3 that covers the outer periphery of the core member 2, a surface layer 10 that covers the outer periphery of the absorbent layer 3, and an outer periphery of the surface layer 10. And an outer cover 5 covering the main body.

The core member 2 is a core member disposed in the center of the mattress 1 and mainly has cushioning properties and body pressure support properties. Moreover, what is called a bottom feeling can be reduced by providing the core part 2. FIG. In the present embodiment, the core member 2 is made of polyester having relatively high air permeability and has a plate shape. In this embodiment, the core part 2 is formed with a thickness of about 150 mm, a width of about 900 mm, and a length of about 1900 mm. However, if the dimensions of the core part 2 are appropriately set according to the design of the mattress 1. Good.

In the present embodiment, the core portion 2 is made of polyester alone, but is not limited to this, and may be provided with a spring, or a material such as latex, urethane, or resin foam. It may be used. Moreover, you may comprise combining these materials. Moreover, what is necessary is just to set the hardness of the core part 2 suitably.

The moisture-absorbing layer 3 covers the outer periphery of the core member 2 in a layered manner, and absorbs moisture such as moisture and human sweat to increase moisture absorption. In the present embodiment, the moisture absorption layer 3 is made of hemp and is laminated with a thickness of about 7 mm. The material of the moisture absorption layer 3 is not limited to hemp, and for example, it is preferable to use a material having a high moisture absorption effect such as felt or needle punch. Further, the thickness of the moisture absorption layer 3 may be set appropriately with a thickness of about 5 mm to 10 mm. In addition, the moisture absorption layer 3 is not necessarily required, and may be appropriately formed as necessary.

As shown in FIGS. 1 to 3, the surface layer portion 10 is composed of a plurality of fibers, and is a portion that covers the outer periphery of the moisture absorption layer 3 in a layered manner. The fiber of the surface layer part 10 employs animal hair in this embodiment. In the present embodiment, the surface layer portion 10 is laminated with the first layer 11, the second layer 12, and the third layer 13 on the outer side from the core material portion 2 side, toward the third layer 13 from the first layer 11. Therefore, the animal hairs constituting each layer are formed so that the hair diameter (outer diameter of the hair) is reduced.

In this embodiment, animal hair is used as the fiber constituting the surface layer portion 10, but is not limited to this, for example, other natural materials such as hemp and cotton or artificial materials such as chemical fibers. A filamentous material may be employed.

As shown in FIG. 3, the first layer 11 is a fiber layer formed in a layered form by intertwining horse hairs, and covers the outer periphery of the moisture absorption layer 3. The horse hair constituting the first layer 11 has a hair diameter of about 75 to 280 μm, and the average hair diameter of the first layer 11 is about 140 μm. The length of the horse hair is 150 mm to 200 mm, which is relatively long. In this way, the hair diameter is relatively larger than those of the second layer and the third layer, which will be described later, and by using long hairs, it is possible to mainly improve supportability and moisture permeability.

Further, only the hair is used for the horse hair used in the first layer 11. Here, as shown in FIG. 4, depending on the type of animal hair J, there is one having a scale S protruding in a scale shape toward the outside. In the present embodiment, the animal hair J that does not include the scale S is referred to as “hair”, and the animal hair J that includes the scale is referred to as “wool”.
Since the hair does not have the scale S, the hair has a property that the hairs are not easily entangled with each other and are not easily set. That is, in the 1st layer 11, since only hair is used, since hairs are hard to get entangled and it is hard to become a pill, it can control settling.

On the other hand, since wool has scale S, it is easy to get entangled with other hairs and is easy to wear, but has the property of being rich in flexibility and heat retention.

In the present embodiment, the second layer 12 is a fiber layer formed by intertwining yak hairs, and covers the outer periphery of the first layer 11. The second layer 12 is formed by mixing yak hair and wool at substantially the same ratio. The yak bristles constituting the second layer 12 have a bristle diameter of 15 to 230 μm, and the average bristle diameter of the second layer 12 is about 111 μm. Yak hair having a length of 80 mm to 150 mm is used.

In the present embodiment, the third layer 13 is a fiber layer formed by entangled the hair of camel hair and the wool of goat (cashmere) at the same ratio, and covers the outer periphery of the second layer 12. . As the camel hair and goat hair constituting the third layer 13, those having a hair diameter of 12 to 120 μm are used, and the average value of the hair diameter of the third layer 13 is about 75 μm. The lengths of camel hair and goat hair are 60 mm to 80 mm.

In addition, the animal hair used for the first layer 11 to the third layer 13 is not limited to those described above, and other types of animal hair may be provided. Moreover, although the hair and wool were mixed in the 2nd layer 12 and the 3rd layer 13, you may comprise each layer only with hair. The second layer 12 and the third layer 13 may be composed of a mixture of 80 mm to 150 mm long fibers and curly hair.

The outer cover 5 is a member that covers the outer periphery of the surface layer portion 10 and wraps the core material portion 2, the moisture absorption layer 3, and the surface layer portion 10. The material of the outer cover 5 is not particularly limited. For example, a cotton fabric (hereinafter referred to as cotton cloth) is used. In the outer cover 5, it is preferable that animal hair constituting the surface layer portion 10 does not penetrate the outer cover 5. The eyes are preferably closed with respect to the eyes of the cotton cloth (the gap between the threads forming the cotton cloth).

Further, as shown in FIGS. 1 and 2, the mattress 1 is formed with

binding portions

8, 8,... Binding the front surface and the back surface of the outer cover 5. The binding portion 8 is formed of a binding thread, and includes a penetration portion 8c that penetrates from the front surface to the back surface of the outer cover 5, and

tufts

8a and 8b that are formed at both ends of the penetration portion 8c. The binding portion 8 is formed by passing the binding thread from the front surface to the back surface of the outer cover 5 and then binding the excess portion of the binding yarn by the

tufts

8a and 8b while applying a predetermined tension. According to the binding portion 8, the core material portion 2 and the surface layer portion 10 can be prevented from moving relative to the outer cover 5.

Further, as shown in FIG. 1, a fastener 9 is formed on the side surface of the mattress 1. The fastener 9 is formed in the center in the height direction across the side surface 1a, the side surface 1b, and the side surface 1c of the mattress 1. Since the side surface 1d of the mattress 1 is not provided with the fastener 9, the outer cover 5 is formed to open from the side surface 1d when the fastener 9 is fully opened. A fastener 9 may be provided over the entire side surface of the mattress 1.

Next, a method for manufacturing the mattress 1 will be described.
First, the core part 2 is formed with a predetermined dimension using polyester. Then, the hygroscopic layer 3 is formed so as to cover the periphery of the core part 2 with layered hemp.

Here, the first layer 11, the second layer 12 and the third layer 13 constituting the surface layer part 10 sufficiently unravel the horse hair, yak hair, camel hair and goat hair used for each, for example, The mixture is fed to a blending machine equipped with scraping blades, and each layer is formed in advance.
Then, the first layer 11 is formed by overlapping a fiber layer made of horse hair around the hygroscopic layer 3. Next, a fiber layer made of yak hair is stacked around the first layer 11 to form the second layer 12. Next, a fiber layer made of camel hair and goat hair is stacked around the second layer 12 to form the third layer 13.

Next, the third layer 13 is covered with the outer cover 5 which has been preliminarily crushed, and the fastener 9 is closed. Finally, the

spelling portions

8, 8... Are formed at appropriate positions to complete the mattress 1. The manufacturing process of the mattress 1 is not limited to the above-described process.

According to the mattress 1 according to the present embodiment described above, the vicinity of the outer periphery of the core member 2 is covered with the first layer 11 formed of fibers (animal hair) having a large outer diameter, and thus is relatively elastic. It is possible to relieve the feeling of contact between the human body and the core part 2 having a large and high hardness. In addition, since the gap between the animal hairs having a large outer diameter becomes a relatively large space, moisture such as moisture and sweat easily passes through the first layer 11. Therefore, moisture (moisture) can be prevented from accumulating inside the mattress 1.

Moreover, while providing the core part 2, and the outer periphery vicinity of the core part 2 is covered with the 1st layer 11 formed with the fiber (animal hair) with a large outer diameter, cushioning property, body pressure support property Can be increased. Moreover, since the hair diameter of the animal hair of the surface layer part 10 becomes small as it leaves | separates from the core material part 2, the core material part 2 side becomes comparatively hard, the outer side becomes comparatively soft, and improves body pressure dispersibility. Can do.

Moreover, since the hair diameter of the animal hair of the surface layer part 10 becomes smaller as it is separated from the core part 2, the outer side becomes a relatively soft layer, and the touch feeling can be improved. Moreover, by mixing wool with the 2nd layer 12 and the 3rd layer 13, animal hair becomes easy to get entangled, and a softness | flexibility and heat retention can be improved.

In addition, by using animal hair for the surface layer portion 10, it is possible to enhance moisture release and further improve heat retention. Moreover, since animal hair is comparatively hard, body pressure supportability can be improved more. Thereby, it can prevent that the location which hits the buttocks of the mattress 1, for example, locally gets loose.

Here, animal hair has the property of being excellent in moisture release and moisture permeability but inferior in hygroscopicity. Therefore, when the mattress 1 is configured only with animal hair, moisture that has once permeated into the surface layer portion 10 may flow backward to the human body and may cause discomfort to the person. However, in the present embodiment, by providing the moisture absorbing layer 3, the moisture absorbing layer 3 absorbs moisture, so that it is possible to prevent moisture that has once penetrated into the surface layer portion 10 from flowing back to the human body side.

That is, as shown in FIG. 5, moisture and moisture such as sweat (see arrows in FIG. 5) generated from the human body H pass through the upper surface layer 10 and are absorbed by the moisture absorbing layer 3 having a high moisture absorbing effect. Then, moisture and moisture such as sweat gradually fall due to gravity and are released to the outside in the left-right direction through the lower surface layer portion 10 '. In the present embodiment, since the surface layer portion 10 (10 ′) uses animal hair having high moisture release properties, the moisture absorbed by the moisture absorption layer 3 is not condensed on the lower surface layer portion 10 ′. , And can be gradually discharged to the outside of the mattress 1. Thereby, the back of the human body can be prevented from becoming damp and sleep can be induced.

Further, since the mattress 1 only covers the periphery of the core part 2 with the hygroscopic layer 3 and a fiber layer composed of a predetermined thickness, the mattress 1 can be manufactured relatively easily and the manufacturing cost is reduced. be able to. Moreover, since the mattress 1 only covers the circumference | surroundings of the core part 2 in layers, a complicated structural calculation etc. are unnecessary and it can raise the freedom degree of design.

In the present embodiment, the contents of the outer cover 5 can be easily taken out by removing the binding portion 8 and opening the fastener 9. Thereby, for example, when the core part 2 has deteriorated over time, the core part 2 can be easily replaced. Conventionally, if the core part 2 deteriorates in terms of age, it has been difficult to make a tailor, so the mattress 1 is often discarded. However, since the mattress 1 of the present embodiment can be easily tailored, the disposal cost can be reduced.

Although the embodiment of the present invention has been described above, the present invention can be modified as appropriate without departing from the spirit of the present invention. For example, in this embodiment, although the surface layer part 10 was comprised using animal hair, you may comprise a surface layer part using chemical fibers, such as polyester and nylon, without being limited to this. Moreover, you may apply the structure of the mattress 1 which concerns on this embodiment to a cushion, the cushion sheet of chairs, a pillow, etc.

In the present embodiment, the surface layer portion 10 has a three-layer structure, but may have a two-layer structure or a four-layer structure or more. Even in this case, it is formed so that the average value of the outer diameters of the fibers constituting each layer becomes smaller (thinner) toward the outside. Moreover, in this embodiment, although the 1st layer 11 was comprised only with hair, you may mix wool.

Further, for example, a net-like net may be provided between the layers constituting the mattress 1. That is, between the moisture absorption layer 3 and the first layer 11, between the first layer 11 and the second layer 12, between the second layer 12 and the third layer 13, and between at least one of the third layer 13 and the outer cover 5. By providing the net in the support, the supportability is improved, and rolling and vibration can be prevented. The size of the net is not particularly limited, but is slightly smaller than the mattress 1. In addition, when a plurality of nets are provided, the hardness of each net may be formed so as to decrease as the distance from the core member 2 increases. In this case, for example, the hardness may be adjusted by decreasing the outer diameter of each net provided (the outer diameter of a member constituting the net portion of the net) as the distance from the core member 2 decreases. Good. According to this structure, it becomes a relatively soft net | network as it goes to the human body side from the core part side, and the touch feeling on the human body side improves more. That is, according to such a configuration, a synergistic effect with the present invention can be produced.
