[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, a mattress in which polyurethane foam is used as a core material and which is covered with a side material has been widely used as a bedclothes. In such a conventional mattress, it is difficult to make it a conventional mattress of the mattress type by giving the roundness because the peripheral edge and the folded portion are square.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to obtain a mattress of a bedding type which has an inclined surface or a curved surface at the outermost peripheral edge and is easily folded when stored.

[0004]

Means for Solving the Problems A mattress base is formed from a plurality of juxtaposed laminates and an elastic foam having a prismatic cross section fixed to the outermost periphery and the outermost peripheral edge of the laminate, and the mattress base of the mattress base is formed. Sides were sewn on the front and back sides with abutting edges and sewn along the elastic foam between the laminates to form a waist.

[0005]

Since the mattress of the present invention has the above-mentioned structure, the elastic foam having a prismatic cross section fixed to the outermost peripheral edge portion of the mattress base has a slanted or curved surface formed on the outer peripheral edge of the mattress by edge stitching. , And the constriction makes it easy to fold the mattress.

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

1 is a core material of the mattress 2 of the present invention, which is made 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 and material, foamed polyolefin mattress with a thickness of about 40 mm, for example, manufactured by Kanegafuchi Chemical Industry 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, in particular, these irregularities constitute muscles of the body. When it is formed so as to be along the direction of the muscle fibers, it is more effective because acupressure effect is given to the body when lying on it or when it is turned over.

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, and the elastic foam 8 having a prismatic cross section such as polyurethane is fixed to the outermost peripheral surface with an adhesive or the like to form a mattress. Form a substrate.

Next, 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 the tip end of the elastic foam 8 adhered to the entire peripheral edge is sandwiched between the front side fabric 9 and the back side fabric 10. Cover the end with the bias tape 11 as shown in 4, and sew 1
2 is performed to form the peripheral edge portion 13. At this time, in order to form a gently sloping surface or a curved surface at the peripheral edge portion, it is appropriate to use the elastic foam body 8 having a triangular cross section.

Further, the connecting portion of the laminated body 6 made of the elastic foam 7 is sewn along the elastic foam 7 to such an extent that the front side cloth 9 and the back side cloth 10 come into contact with each other to form a constricted portion 15. It constitutes the mattress of this invention.

Incidentally, the laminated body 6 in the above-mentioned embodiment is merely an example, and in the case of laminated bodies other than the above in which a plurality of single or different kinds of materials are superposed, it is not necessary to superpose them. It also includes a single item.

[0015]

As described in detail above, the mattress of the present invention comprises a mattress base comprising a plurality of juxtaposed laminates and an elastic foam body having a prismatic cross section fixed to the outermost periphery and the outermost peripheral edge thereof. The side faces of the mattress base are sewn with abutting edges on both sides, and the constricted portions are formed by stitching along the elastic foam between the laminates. In the mattress of the present invention, it was difficult to give a roundness because the periphery and the folded part had a square shape. To a shape with a curved surface, and since the elastic foam portion interposed between the laminated body and the laminated body is sewn to form the constricted portion, folding at the time of storage is also easy,
It was possible to obtain a mattress having a shape similar to that of a conventional mattress with no corners on the periphery.
