Abstract

(57) [Abstract] [Purpose] To obtain a mattress of a futon type which has an inclined surface or a curved surface at the outermost peripheral edge and is easily folded when stored. [Structure] A mattress base is formed from a plurality of juxtaposed laminates and an elastic foam having a prismatic cross section fixed to the outermost peripheral edge of the laminate and side surfaces on both front and back surfaces of the mattress base. A contact edge was sewn and stitched along the elastic foam between the laminates to form a waist.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to bedding, particularly a mattress of a futon type.

[0002]

[Prior art]

 BACKGROUND 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 bedclothing. Such a conventional mattress has a rectangular periphery and a folded part, and thus it is difficult to make it a conventional mattress type mattress by giving it a roundness.

[0003]

[Problems to be solved by the device]

 An object of the present invention is to obtain a mattress of a futon 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 between a plurality of laminated bodies arranged side by side and the laminated body, and an elastic foam having a prismatic cross section fixed to the outermost peripheral edge of the laminated body. The mattress base is brought into contact with both sides of the mattress base. A hem was sewn and stitched along the elastic foam between the laminates to form a waist.

[0005]

[Action]

 Since the mattress of the present invention has the above-mentioned structure, the elastic foam body having a prismatic cross section fixed to the outermost peripheral edge of the mattress base has an inclined surface or a curved surface on the outer peripheral edge of the mattress by edge sewing, and has a constriction. The part makes it easy to fold the mattress.

【Example】

 An embodiment 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 made of completely independent bubbles 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. A foamed polyolefin mattress with a thickness of about 40 mm, which has excellent properties, low thermal conductivity, high heat retention, almost no change in shape and material, for example, "Eperan" manufactured by Kaneka Corporation. Polyethylene foam and polypropylene foam known as 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 the irregularities on the body muscles. When it is arranged and formed along the direction of the muscle fibers that make up the body, it is more effective because the acupressure effect is given to the body when lying down or lying on it.

Reference numerals 3a and 3b are 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 both the front and back surfaces of the core material 1. A far-infrared radiation sheet 4 including a far-infrared radiation body is interposed between the front-side batting layer 3a and the heat-retaining property. 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 attach importance to heat retention.

Further, on the upper surface of the surface-side batting layer 3a, deodorant substances 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 formed by kneading a mildewproof agent into a urethane resin and molding it into a sheet, is advantageously used.

A plurality (three in FIG. 1) of the laminate 6 thus obtained are arranged in parallel, and between the adjacent laminates 6, an elastic foam 7 having a prismatic cross section such as polyurethane is formed. , The contact surfaces with the side faces 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 and the back side fabric 10 are superposed on the front side of the base body, and the back side fabric 10 is superposed on the back side, and the tip of the elastic foam 8 adhered to the entire periphery is sandwiched between the front side fabric 9 and the back side fabric 10. As shown in FIG. 4, the end portion is covered with the bias tape 11, and the edge sewing 12 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 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 14 along the elastic foam 7 to such an extent that the front side fabric 9 and the back side fabric 10 are in contact with each other to form a constricted portion 15. It constitutes the mattress of this invention.

It should be noted that the laminated body 6 in the above-mentioned embodiment is merely an example, and of course, in the case of a laminated body other than the above in which a plurality of single or different materials are laminated, the laminated body 6 It also includes those that consist of a simple substance.

[Effect of device]

 As described in detail above, in the mattress of the present invention, a mattress base is formed from 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. Conventional mattresses such as polyolefin mattresses are formed by abutting edge stitches on both front and back surfaces of the mattress base and stitching along the elastic foam between the laminates to form a constriction. However, it was difficult to give a roundness because the peripheral edge and the folded part had a square shape, but in the mattress of the present invention, an elastic foam was provided at the outermost peripheral edge, and an inclined surface or a curved surface was sewn by edging. Since the elastic foam part interposed between the laminated bodies is sewn to form the constricted part, it is easy to fold when storing and there is no corner on the periphery. Conventional floor It was possible to obtain the mattress of shape similar to Dan.
