Description

  The present invention relates to a mattress that provides good sleep and good sleep, and more particularly to a double-sided mattress that can be used upside down as needed.

  In general, bedding mattresses are well known as mattresses using a sheet-like cushion material having elasticity, such as urethane foam, as a core, in addition to one wrapped with cotton as cloth. In particular, as a cushioning material used for a mattress, a cushioning material in which conical protrusions extending vertically and horizontally are integrally formed on the entire surface on one side is known. According to the mattress using such a cushioning material, a sleeping person lying on the mattress is supported by each apex of the protrusion, so that the breathability is good, and even a bedridden sick person does not rub the floor. Has been used.

  However, although conventional mattresses have good elasticity and provide good sleeping comfort, the heat retention effect is surprisingly small, and people with coldness need an electric blanket or hot water bottle, and in the summer etc. There was a drawback that it was hard to sleep. In addition, even if a cushion material that forms a projection group is used, the above-mentioned difficulties have not been solved, and the projection group is formed only on one surface of the cushion material. When used upside down, there is a problem that the function of the projection is not exhibited at all.

  Therefore, the applicant of the present application has previously developed a mattress (sleeping mat) mainly including a cushion material having both front and rear surfaces with uneven surfaces, and has provided such a mattress for practical use (Patent Document 1).

Registered Utility Model No. 3085871

  However, even with the mattress of Patent Document 1, sufficient breathability was not obtained, and there was a drawback that the bed was stuffy due to sweating of a sleeping person in summer or the like.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a mattress that can be used for both sides, which can reduce the discomfort caused by stuffiness at bedtime and sleep well.

  In order to achieve the above object, the present invention provides a mattress in which a mat body is wrapped with an outer cover, wherein the mat body has a plate-like cushion material forming a ventilation space between a front surface and a back surface, and the cushion material is At least the surface is an uneven surface.

  Further, in a mattress in which a mat body is wrapped with an outer cover, the mat body is formed by wrapping a plate-like cushion material with an inner cover, and the cushion material is formed by laminating three flexible elastic bodies each having one surface having an uneven surface. The middle flexible elastic body has an uneven surface facing either the upper or lower flexible elastic body to form a ventilation space, and a pair of upper and lower flexible elastic bodies sandwiching the intermediate flexible elastic body. Are characterized in that they are laminated with their uneven surfaces facing outward.

  Further, in the mattress as described above, the outer cover is provided with a heating sheet containing a powder of a mineral that emits far-infrared rays, and the heating sheet is provided on one surface of the cushion material having an uneven surface. I do.

  According to the present invention, since the surface of the cushioning material has an uneven surface and a ventilation space is formed between the surface and the back surface, the surface can be turned upside down so that the user can sleep easily even in the summer.

  In particular, since three flexible elastic bodies each having an uneven surface are laminated to form a ventilation space between the front surface and the back surface of the cushioning material, and the front and back surfaces are made uneven, Even when used with the surface facing upward, comfortable sleeping comfort can be obtained.

  In addition, since a thermal sheet containing mineral powder that emits far-infrared rays is provided on the surface of the cushioning material, the far-infrared rays emitted from the thermal sheet do not feel cold even at low temperatures such as in winter. You can sleep well, and you can sleep without feeling the heat and heat with the heat sheet down at high temperatures such as in summer.

  Hereinafter, application examples of the present invention will be described in detail with reference to the drawings. 1 and 2 are perspective external views showing a preferred embodiment of the mattress. FIG. 1 shows an expanded state, and FIG. 2 shows a folded state. As is apparent from these figures, the mattress 1 according to the present invention is equally divided into three regions A, B, and C connected in series via the crease L, and when used, becomes flat as shown in FIG. When it is unfolded and not used, the areas A, B, and C are overlapped as shown in FIG.

  In addition, the present invention does not require that the present invention be a foldable type, but has a distinctive internal structure, and makes this a non-foldable one-piece, two-fold or four-fold type. Is also good. The size is set to, for example, 970 × 1980 × 10 cm for single, 1200 × 1980 × 10 cm for semi-double and 1400 × 1980 × 10 cm for double.

  FIG. 3 is a schematic view showing a longitudinal section of such a mattress. As apparent from this figure, the mattress 1 is constructed by wrapping a mat body 2 with a bag-shaped outer cover 3 made of pure cotton or the like.

  FIG. 4 shows a cross section of such a mat body. As is clear from FIG. 4, the mat body 2 is constituted by using a plate-shaped cushion material 4 having elasticity as a main constituent material, and wrapping the cushion material 4 with a bag-shaped inner cover 5 made of pure cotton or the like. . In particular, the cushion member 4 is formed by laminating three flexible elastic bodies 4A, 4B, and 4C made of a foamed resin (urethane foam in this example).

  As is clear from FIG. 5, each of the flexible elastic bodies 4A to 4C has a concavo-convex surface in which one side of the conical projection 6 is connected vertically and horizontally. In this example, a pair of upper and lower flexible elastic bodies 4A and 4C are laminated with the uneven surface facing outward, and an intermediate flexible elastic body 4B sandwiched between the upper and lower flexible elastic bodies 4A faces the upper layer flexible elastic body 4A. Thus, a ventilation space 7 is formed between the flexible elastic body 4A.

  The middle flexible elastic body 4B and the lower flexible elastic body 4C are bonded back to back with the uneven surface facing outward. It may be molded integrally. In addition, as the lamination type of each of the flexible elastic bodies 4A to 4C, the flexible elastic bodies 4A and 4B are laminated with the uneven surface outside, and the protrusions 6 of the flexible elastic bodies 4B and 4C are abutted, The uneven surfaces of the elastic bodies 4A to 4C and the non-uneven surface may be abutted.

  In FIG. 5, reference numeral 3A denotes a front cloth constituting the outer cover, and 3B denotes a back cloth, and a heating sheet 8 is sandwiched between the front cloth 3A and a middle cloth 3C made of cotton or the like. The heating sheet 8 may be provided inside the inner cover 5 as a constituent material of the mat body 2, but in this example, the heating sheet 8 is provided on the surface of the cushion material 4 (flexible elastic body 4A). And three sheets of intermediate material 3C through the outer cover 3C. In particular, the outer cover 3 is quilted as shown in FIG. 6 so that the heating sheet 8 does not shift.

  Here, the heating sheet 8 is a cloth containing a powder of a mineral that emits far-infrared rays, and tourmaline or precious jewel is suitably used as the mineral. In particular, in the present example, the two upper heating sheets 8 were mixed with a proper amount (5 to 10% by weight) of a tourmaline particle having a particle size of 90% or more and a particle size of 3 μm or less mixed with a melt of polyethylene terephthalate. Fibers (1 to 10 denier) obtained by spinning the mixture are made into sheets. The base material is not limited to polyesters such as polyethylene terephthalate, but also celluloses such as viscose rayon and polyamides such as nylon. System, a polyolefin system such as polypropylene, or an inorganic fiber system such as glass, and the like. Further, as the heating sheet 8, a binder liquid in which tourmaline particles are dispersed with respect to the above-described synthetic fibers and natural fibers such as silk is used. It may be applied.

It should be noted that tourmaline is a cyclosilicate mineral having three-coordinate boron (a mineral having a (SiO ₃ ) _6- membered six-membered ring anion shared by the top of a SiO ₄ tetrahedron), and its chemical composition is represented by the general formula [WX ₃ B ₃ Al ₃ (AlSi ₂ O ₉ ) ₃ (O, OH, F) ₄ ] (W = Na, Ca, X = Al, Fe ³⁺ , Li, Mg, Mn ²⁺ ) Examples are Drabite (W, X = Na, Mg), Squall (W, X = Na, Fe), Ubite (W, X = Ca, Mg), and Elbite (W, X = Na, Li). .

In particular, tourmaline is also called tourmaline and has remarkable pyroelectricity and piezoelectricity, its piezoelectricity is 5.8 × 10 ⁻⁸ esu to 1.1 × 10 ⁻⁷ esu, and its polarization charge is 3.2 × 10 ⁻¹² erg to 1.6 × 10 It is about ^-11 erg.

  Then, according to the heat sheet 8 containing such tourmaline particles, the tourmaline particles emit electromagnetic waves in the far-infrared wavelength region in response to the weight and body temperature of the sleeping person, thereby warming the sleeping person from the core of the body, Moreover, since negative ions are emitted from the tourmaline particles to promote blood circulation and metabolism, it is possible to prevent coldness and stiff shoulders.

  Here, the operation of the mattress 1 configured as described above will be described. First, at a low temperature such as winter, the mattress 1 is laid on a floor or a bed frame with the front side (flexible elastic body 4A) of the cushioning material 4 on which the heating sheet 8 is arranged facing upward, and the mattress 1 Lay on top and hang a comforter (not shown). Then, the outside cold air is shut off, and the body temperature and the body pressure of the sleeping person act on the heating sheet 8. Therefore, the tourmaline particles contained in the heating sheet 8 emit electromagnetic waves and negative ions in the far-infrared wavelength region toward the sleeping person. As a result, the body of the sleeping person is warmed from the core, and blood circulation and metabolism are promoted. Therefore, it is possible to sleep comfortably without using a thick and heavy comforter even in the cold season, and the coldness and shoulder stiffness are improved while sleeping. In addition, tourmaline particles physically adsorb odor components such as ammonia, which cause sweat odor and stuffy odor of the feet, or exhibit electrical decomposability to prevent odors from being absorbed.

  On the other hand, when the temperature is high in summer or the like, the front and back of the mattress 1 are turned upside down as described above, and the back side (the flexible elastic body 4C) of the cushion member 4 is used up. At this time, since the body temperature and the body pressure of the sleeping person acting on the heating sheet 8 are alleviated by the cushion member 4, far infrared rays are hardly generated from the heating sheet 8, and some heat is absorbed and blocked by the cushion member 4. . Therefore, the sleeping person can sleep well even in the hot season without much feeling of heat.

  As described above, the mattress 1 has different functions by using the front and back surfaces. However, even when the mattress 1 is used with the front and back surfaces facing upward, the sleeper's body is in the cushion material 4 (the flexible elastic body 4A or 4C). Since the ventilation space 7 is formed between the front and back surfaces of the cushion member 4 and is supported by each apex of the protrusion 6, the air and the moisture can be kept without a cage, so that a bedridden sick person does not rub on the floor.

  Although the present invention has been described above, the mattress according to the present invention is not limited to the above example, and the outer cover 3 and the inner cover 5 may be made of cloth other than cotton, silk, hemp, or synthetic fibers. Alternatively, the cushion member 4 may be directly wrapped by the outer cover 3 without the inner cover 5. Further, it is preferable that the front and back surfaces of the cushion material 4 are made uneven as in the above example, but only one surface thereof may be made uneven.
