[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION This invention relates to bedding and, more particularly, to a mattress type mattress.

[0002]

2. Description of the Related Art Conventionally, natural or synthetic fiber cotton, wool, feathers, etc. are used as batting, which is covered with a side cloth, or a polyurethane foam is used as a core material, and a mattress is covered with the side cloth. Widely used as.

In these conventional beddings which are highly flexible, it is difficult to maintain a good posture because a specific part of a lying body, such as the waist, is deeply depressed, and sweat escaping from the body is taken into the bedding, and the bedding is In a wet state, the water containing this waste product cools the body and promotes bed sores, etc., and it is not preferable in terms of health and hygiene, such as generation of offensive odor, accompanying bacteria and mold.

[0004]

[Problems to be Solved by the Invention] This device has moderate hardness so that a specific part of the body does not fall when lying down, and it is easy to evaporate moisture such as sweat, deodorant and antibacterial. The purpose of the present invention is to obtain a mattress that is highly deodorant, mildew-proof and anti-mildew, and has excellent health and hygiene performance.

[0005]

[Means for Solving the Problems] A core material made of expanded polyolefin, a batting layer arranged on both front and back surfaces thereof, and a deodorizing property, an antibacterial deodorizing property, and a fungicidal property provided on the surface side batting layer. A mattress base is formed from a laminate composed of a polyurethane sheet (hereinafter simply referred to as a deodorant sheet) and an elastic foam having a prismatic cross section fixed between the plurality of juxtaposed laminates. Sides were abutted and sewn on both sides.

[0006]

Since the mattress of the present invention has the above-mentioned structure, moisture such as sweat generated from the body when lying down on the mattress reaches the deodorant sheet through the front side fabric, and is decomposed by sweat or waste products. The generation of odors, bacteria, fungi, and scallops is prevented, and the moisture that has penetrated into the inside is absorbed by the folds, carpets, etc. that the batting layer placed on the front side of the core material and the back side of the mattress contact. It is absorbed by the batting layer placed on the back side of the core material through the back side ground.

The sweat and moisture absorbed in the batting layer are
The core material, which is a non-absorbent foamed polyolefin mattress, is prevented from further penetrating into the inside thereof, but the heat retention of the foamed polyolefin mattress, that is, since the foamed polyolefin mattresses are closed cells, they are trapped inside the bubbles. The air is heated by, for example, body temperature and exerts a heating effect, and in combination with the air permeability of the fibers forming the batting layer, it can be easily removed by evaporation to the outside.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

Reference numeral 1 is a core material of the mattress 2 of the present invention, which is composed of completely closed cells formed by in-mold molding with a bead method, has a water absorption close to 0, shock absorption, oil resistance, chemical resistance and heat resistance. Rich, low thermal conductivity, high heat retention, almost no change in shape material, foamed polyolefin mattress with a thickness of about 40 mm, for example, manufactured by Kanegafuchi Chemical Co., Ltd.
Polyethylene foam and polypropylene foam known under the trade name "Eperan" are used.

As shown in the figure, the core material 1 can obtain a sufficient effect with a foamed polyolefin mattress having a smooth surface. However, a mattress having irregularities on the surface, particularly these irregularities constitute muscles of the body. When it is arranged and formed so as to be along the direction of the muscular fibers, it is more effective because acupressure effect is given to the body when lying down or lying on it.

Reference numerals 3a and 3b denote batting layers having a thickness of about 15 to 20 mm, which are made of natural fibers or synthetic fibers having a high hygroscopic property, which are in contact with the front and back surfaces of the core material 1, and which have a thickness of about 15 to 20 mm. A far-infrared radiation sheet 4 including a far-infrared radiation body is interposed between the side filling layer 3a and the side filling layer 3a to enhance heat retention. However, the far-infrared radiation sheet 4 does not necessarily have to be provided, and it is suitable to dispose the far-infrared radiation sheet 4 when it is used as a mattress for a sick person or an elderly person who particularly needs to prevent lowering of body temperature and emphasizes heat retention.

Further, on the upper surface of the surface side batting layer 3a, a deodorant substance obtained by impregnating various deodorant components into silica gel, and an antibacterial deodorant obtained by blending an iodine drug and an imidazole drug, A deodorant sheet 5 known as "orderless" manufactured by Daiyu Shoji Co., Ltd., which is obtained by kneading a drug having a high antifungal property into a urethane resin to form a sheet, is advantageously used.

A plurality (three in FIG. 1) of the laminated body 6 thus obtained are arranged in parallel, and between the adjacent laminated bodies 6, an elastic foam 7 having a prismatic cross section such as polyurethane is formed. And the contact surfaces with the side surfaces of the laminate 6 are fixed to each other with an adhesive or the like to form a mattress base. If necessary, an elastic foam 8 having a prismatic cross section, such as polyurethane, may be fixed to the outermost peripheral surface with an adhesive or the like.

Then, the front side fabric 9 is superposed on the front side of the base body, and the back side fabric 10 is superposed on the back side thereof, and as shown in FIG. 4, the end portions are covered with the bias tape 11, and the edge sewing 12 is performed to perform the peripheral edge portion 1.
3 is formed.

The connecting portion of the laminated body 6 made of the elastic foam 7 is sewn 14 along the elastic foam 7 to such an extent that the front side cloth 9 and the back side cloth 10 contact each other to form a constricted portion 15. The lever mattress may be constructed.

The mattress of the present invention has the above-mentioned structure, so that a sufficient effect can be obtained, but when the surface side batting layer 3a cannot sufficiently alleviate the feeling of assembling the core material 1. May be replaced with a high specific gravity polyurethane having a thickness of about 10 mm in place of the surface side filling layer 3a. In this case, it is desirable that the high specific gravity polyurethane has substantially the same hygroscopicity as the surface side filling layer 3a. .

[0017]

As described in detail above, the mattress of the present invention has a core material made of foamed polyolefin, a batting layer arranged on both front and back surfaces thereof, and a deodorant and antibacterial layer provided on the front side batting layer. A mattress base is formed from a laminate composed of a polyurethane sheet having deodorant and antifungal properties, and an elastic foam having a prismatic cross section fixed between the laminates juxtaposed to each other, and both sides of the mattress base are formed. The foamed polyolefin mattress used as the core material has almost no change in shape because it is sewn on the side with the side edges, so unlike conventional mattresses and polyurethane mattresses that are rich in elasticity, it is laid on it. However, since the body does not sink and it is rich in heat retention, it is possible to maintain the same temperature environment as before going to bed, even if the body temperature drops during bedtime, Due to the excellent heat effect of the batting layer, the water absorbed by the batting layer is removed to the outside, and the batting layer reduces the rough and rigid feeling given to the body by the core material, and in combination with the presence of the deodorant sheet, it is always dry. You can get a comfortable feeling and a clean and hygienic sleeping environment.
