Is preferably performed.

[0009]

[Embodiment of the invention]

 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 sleeping mat, wherein FIG. 1 shows an expanded state and FIG. 2 shows a folded state. As is apparent from these figures, the sleeping mat 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, is flattened as shown in FIG. When not in use, the respective areas A, B, and C are overlapped as shown in FIG.

Note that the present invention does not require that the present invention be a foldable type, but has a distinctive internal structure, which can be made into a single non-foldable type, a two-fold type or a four-fold type. You may do it. Incidentally, 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 cross-sectional view taken along line XX in FIG. 1, and FIG. 4 is a schematic diagram of the cross section. As apparent from these figures, the sleeping mat 1 is generally constructed by wrapping a mat body 2 with a bag-shaped outer cover 3 made of pure cotton. The mat body 2 is mainly composed of a plate-like cushioning material 4 having elasticity. The cushioning material 4 is wrapped with a bag-like inner cover 5 made of pure cotton. It is configured to house a mesh sheet 7 in a shape.

The cushion member 4 is made of a flexible foamed resin (urethane foam in the present embodiment), and the front and rear surfaces thereof are formed as concavo-convex surfaces in which conical projections 8 extend vertically and horizontally. In particular, the cushioning member 4 is composed of a pair of upper and lower laminates 4A and 4B each having one surface as an uneven surface, and the two laminates 4A and 4B are stacked back to back with the uneven surface facing each other. ing. Note that the cushion member 4 may be formed in a single plate shape, and the projections 8 may be integrally formed on both front and back surfaces.

The mesh sheet 7 is provided on one side (back side) of the cushion material 4 via the polyester sheet 6. In this example, the mesh sheet 7 is a synthetic fiber cloth having a thickness of 1 to 2 mm, and hexagonal meshes 7A each having a diameter of several millimeters are formed continuously on the entire surface as shown in FIG. The base material has a composition of 70% nylon and 30% polyester. The mesh sheet 7 having such a honeycomb structure forms an air layer inside the hexagonal eyes 7A, and functions to keep moisture or hot air from sweating at bedtime from being trapped. Note that a thick race having square eyes may be used as the mesh sheet 7.

On the other hand, a heating sheet 9 containing tourmaline particles is provided on one surface of the cushion material 4. The heating sheet 9 may be provided inside the inner cover 5 as a constituent material of the mat body 2, but in this example, two sheets are provided on the mat body 2 on the front surface side of the cushion material 4 via the nonwoven cloth 10. Can be In particular, the heating sheet 9 and the nonwoven fabric 10 are located between the mat body 2 and the outer cover 3 and are sewn to the outer cover 3 by quilting as shown in FIG.

Here, in the heating sheet 9, a proper amount (5 to 10% by weight) of tolmarin particles having 90% or more and a particle size of 3 μm or less is mixed with a melt of polyethylene terephthalate, and the mixed solution is spun. The fiber (1 to 10 denier) obtained by sheeting is made into a sheet. The base material is not limited to polyester such as polyethylene terephthalate, cellulose such as viscose rayon, polyamide such as nylon, or polypropylene. Or a polyolefin-based material such as glass, or an inorganic fiber-based material such as glass. Further, as the thermal sheet 9, a binder liquid in which tourmaline particles are dispersed is applied to the synthetic fiber or natural fiber such as silk as described above. May be.

Note that tourmaline is a cyclosilicate mineral having three-coordinate boron (a mineral having a (SiO ₃ ) _6- membered ring anion due to vertex sharing of a SiO ₄ tetrahedron), and its chemical composition is represented by the general formula Is represented by [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⁺ ). Typical examples are a driver (W, X = Na, Mg), a squall (W, X = Na, Fe), a wobite (W, X = Ca, Mg), and an elvite (W, X = Na, Mg). Li).

In particular, tourmaline is also called tourmaline and has remarkable pyroelectricity and piezoelectricity, and has a piezoelectric constant of 5.8 × 10 ⁻⁸ esu to 1.1 × 10 ⁻⁷ esu and a polarization charge of 3.2 × 10 ⁻¹² erg. About 1.6 × 10 ^-11 erg.

According to the thermal sheet 9 containing such tourmaline particles, the tourmaline particles radiate electromagnetic waves in the far-infrared wavelength region in response to the weight and body temperature of the sleeping person. It warms from the core and emits negative ions from the tourmaline particles to promote blood circulation and metabolism, thereby preventing chilling and stiff shoulders.

Here, the operation of the sleeping mat configured as described above will be described. First, at a low temperature such as in winter, the bed mat 1 is laid on a floor or a bed frame with the heat sheet 9 on the side of the laminate 4A facing upward, and the bed is laid on the mat 1 and a hook (not shown). Hang a futon. 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 9. For this reason, the tourmaline particles contained in the heating sheet 9 emit electromagnetic waves and negative ions in the far-infrared wavelength region toward the sleeping person. As a result, the sleeper's body is warmed from the core and blood circulation and metabolism are promoted. Therefore, it is possible to sleep well without using thick and heavy comforters even in the cold season, and to improve the coldness and stiff shoulders while sleeping. In addition, tourmaline particles physically adsorb odor components such as ammonia, which are the cause of sweaty odors and stuffy odors, or decompose electrically to exhibit the deodorizing effect of preventing odors. I do.

On the other hand, when the temperature is high in summer or the like, the mat 1 is used upside down with the mesh sheet 7 on the side of the laminate 4B facing upward. At this time, since the body temperature and body pressure of the sleeping person acting on the heating sheet 9 are relieved by the cushion material 4, far infrared rays hardly occur from the heating sheet 9, and some heat generation is absorbed and blocked by the cushion material 4. You. In addition, an air layer is formed just below the sleeping person's body between the projection 8 of the cushioning material and the eye 7A of the mesh sheet to promote ventilation. But I can sleep well without feeling so hot.

As described above, the sleeping mat 1 exerts different functions by using the front and back surfaces, but the sleeper's body is supported by each apex of the projection 8 in the cushion material 4 when using both the front and back surfaces. Therefore, it is comfortable to sleep on and the floor is not rubbed with heat or moisture.

Although the present invention has been described above, the sleeping mat 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 cotton, silk, hemp, synthetic fiber, or the like. Is also good. Alternatively, the cushion member 4 and the like 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 member 4 are made uneven as in the above example, but only one surface may be made uneven surfaces, or both the front and back surfaces may be made smooth surfaces.

[0023]

[Effect of the invention]

 As is clear from the above description, according to the present invention, since the front and back surfaces of the cushioning material are formed as projections and depressions, a comfortable sleeping comfort can be obtained even when both surfaces are used.

In addition, since a thermal sheet containing tourmaline particles is provided on the surface of the cushioning material, the far infrared rays and negative ions radiated from the tourmaline particles do not cause a sense of cold even at low temperatures such as in winter. It sleeps well and eliminates the odor of sweat and stuffy odor due to the deodorant effect of tourmaline particles.

Further, since a porous mesh sheet is provided on the back side of the cushion material, an air layer is formed in the lower part of the body, and ventilation is promoted by a synergistic action with the cushion material. Even when the temperature is high, I can sleep well without feeling the heat.
