Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to a futon to be used at home, and adjusts the warmth of the futon according to temperature changes in four seasons so that the user can always sleep comfortably.

[0002]

[Prior art]

 A typical mattress is made by filling a cloth bag with cotton, wool, or synthetic fiber padding and closing its mouth. It is also practiced to wrap and cover the above-mentioned cotton, wool or synthetic fiber cotton on a plate-shaped support mat made of hard cotton, synthetic resin or rubber foam, and pack it in the above bag. . These mattresses are lined with sheets and used in the same form all year round, and they usually rely on quilts to adjust heat retention in response to temperature changes during the four seasons, especially in cold weather. During the harsh winter season, an electric blanket and a heating device such as a kotatsu were additionally used.

[0003] Recently, in response to consumer's tendency to become healthier and more comfortable, hot air is put into the sardines and a sheet heating element is put in the support mat. Came. However, these methods are measures for cold winters, and do not cool the inside of the sardines during hot summers.

[0004]

[Problems to be solved by the device]

 In this invention, by replacing the inner pad, the heat insulation of the mattress can be adjusted in response to temperature changes during the four seasons.

[0005]

[Means for Solving the Problems]

 The mattress of the present invention comprises a plate-like support mat having hard cotton-like cushioning properties and breathability, a heat-insulating pad using fibers having good heat-insulating properties, and an ordinary medium between the outer material and the inner material. It consists of a bag-shaped cushion that can be opened and closed so that the above-mentioned support mat and heat-insulating pad can be covered in a bag-like manner by cushioning cloth that is sandwiched and bound by quilting. It can be used by stacking the above-mentioned support mat and heat-insulating pad inside, putting only the support mat on top of the heat-insulating pad on the bag-shaped cushion, or taking out only the support mat from the bag-shaped cushion. It is characterized by doing so.

In the present invention, the plate-shaped support mat has a cushioning property like a hard pad and breathability, and in particular, the filament of a thermoplastic elastomer having thermoplasticity and rubber-like elasticity is heated to a high temperature. A spunbonded non-woven fabric-like structure obtained by extruding underneath and immediately collecting it on a flat surface while being rapidly cooled and fusing the contact portions of the filaments with each other and an entangled structure having vesicle-like voids are preferable. As the above-mentioned thermoplastic elastomer, a polyester-based elastomer in which polyester such as polyethylene terephthalate or polybutylene terephthalate is used as a hard segment and aliphatic polyether such as polytetramethylene glycol is used as a soft segment is preferable.

The preferable apparent density of the support mat made of the thermoplastic elastomer filaments is 0.025 to 0.045 g / cm ³ , and the thickness thereof is preferably 20 to 50 mm. When the apparent density is less than 0.025 g / cm ³ , a feeling of flooring occurs, while when it exceeds 0.045 g / cm ³ , folding during storage becomes difficult and heavy. Further, if the thickness is less than 20 mm, a feeling of flooring is generated and the heat retaining property is insufficient, and conversely, if it exceeds 50 mm, folding during storage becomes difficult.

Examples of the plate-like support mat include a needling non-woven fabric made of synthetic fibers instead of the entangled structure, a hard cotton or polyurethane obtained by heat-bonding synthetic fiber cotton under pressure, A foam made of synthetic resin such as polyethylene can also be used. However, the cells of the foam are preferably open cells, and the cells of the closed cells can be used by providing a large number of through holes in the thickness direction thereof. The open area ratio on the surface of these foams is preferably 10% or more. If the open area ratio is less than 10%, the air permeability becomes poor. The above-mentioned support mat may be used as it is in a naked state or may be put in a wrapping cloth, but if the support mat is used only as a mattress in the summer as will be described later, it may be used as a wrapping cloth. It is preferable to use it by putting it in.

The heat-insulating pad used by being stacked on the above-mentioned support mat uses fibers having a good heat-insulating property for the inner cotton. Examples of such fibers include moisture-absorbing and heat-generating fibers such as wool and acrylate-based fibers that are excellent in moisture-absorbing and heat-generating properties, and infrared-reflecting fibers that excel in the reflection of far-infrared rays emitted from the human body, such as carbon fibers and far-infrared reflecting ceramics. Examples thereof include synthetic fibers such as kneaded polyester fibers and acrylic fibers. Further, as the carbon fiber, a pitch-based carbon fiber which is difficult to break is particularly preferable.

The above-described hygroscopic heat-generating fiber and far-infrared reflecting fiber can be used alone or in combination for the inner pad of the heat-insulating pad, but it is not necessary to use synthetic fiber such as polyester fiber or other common futon. It can also be used as a mixture. However, when it is mixed with normal futon cotton, it is preferable to set the amount of the above-mentioned moisture absorbing and heat-generating fibers, far infrared ray reflecting fibers and the like having good heat retaining properties to 30% or more of the total amount of the middle cotton. If it is less than 30%, the effect of use cannot be obtained.

[0011] basis weight of the middle cotton in heat insulation pad above, 100 to 600 / m ² is laid like this basis weight can not be obtained thermal effect is less than 100 g / m ^2, opposite to the 600 g / m ² Beyond that, the mattress becomes too soft and becomes uncomfortable. The wrapping of the heat retaining pad is preferably made by using a relatively dense fabric such as cotton fabric or polyester / cotton blend fabric for the surface and lining.

The bag-shaped cushion covering the support mat and the heat-insulating pad is formed in a bag-like shape with a cushion material formed by sandwiching a normal padding between the outer material and the inner material and tying it by quilting. Both the above-mentioned outer material and the inner material are preferably cotton fabrics or polyester / cotton mixed fabrics, and relatively dense fabrics are used for the outer material and relatively coarse textured fabrics are used for the inner material. Then, a bag is made by stacking the outer material and the inner material, and the inner cotton is stuffed inside.

The padding may be any of natural fibers such as wool and cotton, synthetic fibers such as polyester and acrylic, or a mixture of the above-mentioned natural fibers and synthetic fibers, and is appropriately selected according to requirements. Basis weight in said cotton, 150~500g / m ² is rather preferable, poor heat retention in winter is less than 150 g / m ^2, cold at bedtime Te radiator size Kuna' from Shikibuton, 500 g in the opposite If it exceeds / m ² , when forming a bag with the cushioning material described below to form a bag-shaped cushion, two cushioning materials will overlap vertically, and the total basis weight of the cushioning material on both the upper and lower sides will exceed 1000 g / m ² . The bag-shaped cushion is heavy and bulky, making it difficult to store.

[0014] The above-mentioned outer material and the inner material can be covered with a cushioning material which is joined by quilting after inserting the inner wadding between them and the supporting mat and the heat-insulating pad are overlapped with each other. Naive bag is made. An opening for inserting and removing the support mat or the like is provided along at least one side of this bag, preferably over two or three sides, and an opening / closing tool such as a slide fastener is attached to this opening. A bag-like cushion is formed.

The mattress composed of the support mat, the heat-insulating pad and the bag-shaped cushion is used as follows. For example, in the spring and autumn, the support mat and the heat-insulating pad are placed in the bag cushion with the support mat facing up, and the sheets are laid on the upper surface of the bag cushion to sleep. In some cases, the heat-insulating pad may be removed and only the support mat may be put in for use. In winter, put only the support mat in the bag-shaped cushion, overlay the heat-insulating pad on the upper surface of the bag-shaped cushion, and lay the sheets on it. In this case, since there is a heat retaining pad on the side in contact with the sleeping person, the heat retaining property is the highest. In the summer, the bag-shaped cushion and the heat-insulating pad are stored, only the supporting mat is used, and the sheets are laid on it to sleep. In this case, heat dissipation is maximized, and you can sleep coolly.
