Description

  The present invention relates to a mattress, and more particularly to a mattress that can sleep well during summer sleep.

  In recent years, polyester cotton has been widely used as a batting material for mattresses. This material is lighter and cheaper than cotton, which is the traditional natural material.

  However, when the above-mentioned mattress is used during sleep in the summer, the user sweats on the back, and the polyester cotton has a problem of being unable to sleep well because of its poor hygroscopicity and suffocating, resulting in poor morning awakening. In addition, the polyester cotton material has a problem that it lacks elasticity and is easy to sag with time.

  Therefore, appropriate perforations of flat shape are made up and down, right and left over the entire surface of the elastic thick plate made by compressing and solidifying synthetic cotton such as polyester raw material so that there is a waist with appropriate elasticity and stickiness. There has been proposed a central material which is continuously arranged in parallel in a direction and formed into a mesh shape (see Patent Document 1). In addition, it has good heat insulation and cushioning properties, and a warming quilt part made of cotton, wool, etc. as a central material, and has a breathable and cushioning support strength that is harder than the warming quilt part. There is also a mattress that consists of a breathable futon part that is held and is fixed by installing both the mattress parts (see Patent Document 2).

No. 3094019 Japanese Utility Model Publication No. 5-68359

  However, the central material proposed in Patent Document 1 uses synthetic cotton made of polyester raw material, processed into solid cotton, continuously perforated in the vertical and horizontal directions, and has air permeability and elasticity. However, there was no technical disclosure regarding a structure in which a user can sleep well using this central material. In addition, the quilt described in Patent Document 2 is a structure in which a quilt part for heat insulation and a quilt part for ventilation are attached to each other, and a plurality of materials are required for both quilt parts, There was also a problem that manufacturing cost and time were required.

  The present invention has been made in view of the above-described problems, and provides a mattress that can be easily manufactured with a simple structure and can sleep well during sleep in summer.

  For this reason, the mattress of the present invention comprises a cushion layer made of synthetic fibers and having a three-dimensional solid knitted structure, a solid cotton layer in which polyester cotton is heated and compressed and an appropriate through hole is formed on the entire surface, and the solid fabric layer. The first feature is that cotton fabrics provided in contact with the cotton layer are sequentially laminated and sewn with a thread material for futon sewing.

  Further, the solid cotton layer is formed by laminating a plurality of polyester cottons having different melting points and a cotton material formed by stirring a binder having a lower melting point than the cotton, and heating at the melting point of the binder. The second characteristic is that it is a solid cotton.

  The solid cotton may not have a through-hole portion, and the thickness of the cushion layer and the solid cotton layer of the three-dimensional solid knitted structure is preferably 10 to 20 mm.

  According to the mattress of the present invention, a cushion layer having a three-dimensional solid knitted structure, a solid cotton layer having appropriate through-holes formed on the entire surface, and a cotton fabric are laminated and sewn. Deformation of the cushion layer due to a person's load is alleviated, and the body does not sink into the cushion layer, thus providing an excellent effect of good ventilation.

  In addition, an appropriate through-hole is formed on the entire surface of the solid cotton layer, and the breathability in the thickness direction of the mattress is obtained, so that moisture accumulates, and is particularly comfortable during sleep in summer. It has an excellent effect.

It is a perspective view which shows one Example of the mattress of this invention. It is a fragmentary sectional view of FIG. It is explanatory drawing which shows a solid cotton layer. It is sectional explanatory drawing which shows one Example of the mattress of this invention.

  Hereinafter, although the mattress of the present invention will be described based on one example, it goes without saying that the present invention is not limited to this example. FIG. 1 is a perspective view showing an embodiment of a mattress according to the present invention, FIG. 2 is a partial sectional explanatory view of FIG. 1, FIG. 3 is an explanatory diagram showing solid cotton, and FIG. 4 shows an embodiment of the mattress according to the present invention. FIG.

  1 and 2 show a mattress of the present invention, FIG. 1 is a perspective view, and FIG. 2 is a partial cross-sectional explanatory view of FIG. As shown in the figure, a mattress 1 of the present invention comprises a cushion layer 2 in which polyester fibers are formed into a three-dimensional solid knitted structure, a solid cotton layer 3 made of polyester fiber cotton, and a printed fabric 4 made of cotton. It is configured.

  As the cushion layer 2, a polyester 3D three-dimensional knitted fabric (trade name) “Fusion” made by Asahi Kasei Fiber with a thickness of 10 mm can be suitably used, and it has excellent shape retention characteristics and elasticity due to its pillar / stiff structure. In addition, the three-dimensional solid knitting structure is excellent in air permeability.

  The solid cotton layer 3 is a solid cotton having a thickness of 10 mm formed by heating and compressing a polyester cotton material. Two types of polyester cotton material and a binder fiber having a low melting point compared to the polyester cotton material are existing. A plurality of thin cotton sheets formed by a cotton making apparatus are laminated and heated, pressure-bonded and cooled to be processed into a 10-mm thick solid cotton.

  The printed fabric 4 is a normal 100% cotton fabric, which is formed by sequentially laminating the cushion layer 2 and the solid cotton layer 3 and arranged on the solid cotton layer 3 side. 5 and is sewn. In addition, when sewing the cushion layer 2, the solid cotton layer 3, and the printed fabric 4 of the main mattress 1, the center portion of the mattress 1 is not subjected to saddle stitching or quilting, so that air permeability is good.

  FIG. 3 is an explanatory view showing solid cotton, and a large number of substantially diamond-shaped holes 6 are formed by a mold or the like through the surface of the solid cotton layer 3 made of the above-described polyester fiber. With this configuration, the solid cotton layer 3 can improve the ventilation from the front surface to the back surface and can be reduced in weight. In addition, the shape of the hole 6 is not limited to the rhombus, but may be other shapes.

  When the mattress having the above-described configuration is used in the summer, the user can use the cushion layer as a front side, for example, by superposing it on an existing mattress. With this configuration, the user does not sink his body at bedtime, and the laminate of the cushion layer and the solid cotton layer, which is excellent in air permeability, has good ventilation and can sleep comfortably without getting muddy. Further, in winter, the printed fabric is used as the front side with the cushion layer facing down, so that heat of the body is not dissipated to the outside, and comfortable sleep is possible.

  FIG. 4 is a cross-sectional explanatory view showing another embodiment of the mattress of the present invention, and the mattress 1 described above, the cushion layer 2 and the printed fabric 4 are equivalent. Further, the solid cotton layer 3 is formed by heating and compressing a polyester cotton material to have a thickness of 10 mm, and unlike the above-described embodiment, a substantially rhombic hole is not formed.

  As in the above-described embodiment, the mattress having this configuration can use the cushion layer as the front side, for example, by superposing it on an existing mattress. With this configuration, the user does not sink his body at bedtime, and the laminate of the cushion layer and the solid cotton layer, which is excellent in air permeability, has good ventilation and can sleep comfortably without getting muddy. Moreover, in the winter season, comfortable sleep can be achieved in the same manner as a normal mattress by using the printed fabric as the front side with the cushion layer facing down.

  As described above, the mattress according to the present invention comprises a cushion layer having a three-dimensional solid knitted structure, a cotton layer made by heating and compressing polyester cotton, and an appropriate through-hole portion formed on the entire surface, and in contact with the cotton layer. Since the provided cotton fabrics are laminated in order and sewn with the futon sewing thread material, the user can sleep comfortably in the summer.
