Abstract

[PROBLEMS] To provide a mattress that has a plurality of convex portions suitable for dispersion of body pressure that does not cause bottoming feeling while reducing labor for manufacturing the mattress, and that provides a good sleeping posture.
SOLUTION: Point-like binding portions 7 which are bound so that an upper fabric 2 and a lower fabric 2 are close to each other with a thread penetrating in the thickness direction of the futon are provided at a plurality of positions at substantially equal intervals, The cotton layer 3 and the urethane foam layer 4 are compressed by being sandwiched by the upper and lower fabrics 2 into the center side in the thickness direction of the duvet accompanied with the pulling to the binding portion 7 side, and the cotton layer 3 and the urethane foam layer resisting the compression 4, a plurality of bulge-shaped convex portions 8 that are convex outwardly due to both reaction forces are positioned on the upper and lower surfaces of the futon, and via a valley-shaped portion 9 that is positioned on a line connecting adjacent binding portions 7. The protrusions 8 are arranged side by side.

Description

  The present invention relates to a mattress.

Conventionally, in a mattress or the like, it has been considered to provide a plurality of convex portions on the surface side in contact with the body so that the body pressure can be dispersed in the sleeping posture. And in order to obtain a mattress on which the body itself is in contact with a plurality of convex portions, a section is formed by previously binding the upper and lower fabrics at a plurality of locations, and a packing material such as rolled cotton is arranged in each section. The idea to do is proposed (for example, refer patent document 1).
JP 2003-310390 A (paragraph number 0017, FIG. 1)

However, as described above, a configuration in which each of the compartments formed in advance is filled with a rounded filling material requires labor for manufacturing the mattress and increases costs. In addition, since there is no filling between adjacent convex portions, there is a problem that a feeling of bumpiness or a stepped feeling occurs when taking a sleeping posture.
On the other hand, it is conceivable to form a plurality of convex portions by arranging cotton material as a filling material between the upper and lower fabrics, and then binding the upper and lower fabrics at a plurality of locations. When using the mattress, there is a lack of support in the part that receives the body, and there is the inconvenience that a feeling of bottoming occurs when used, and the effect of supporting the body with many convex parts and distributing body pressure Will not show.
Therefore, in view of the above circumstances, the present invention aims to have a plurality of convex portions suitable for body pressure dispersion that do not cause bottoming feeling while reducing the labor of manufacturing a mattress, and has a good sleeping posture. The purpose is to obtain the obtained mattress.

  The present invention has been made in consideration of the above-mentioned problems, and between the upper and lower fabrics, a filler layered in the order of a cotton layer, a urethane foam layer, and a cotton layer is disposed in the direction of the thickness of the futon, Duvet thickness that is provided in multiple places at approximately equal intervals in the form of dotted binding parts that are bound so that the upper and lower fabrics come close to each other with thread that penetrates in the direction, and the upper and lower fabrics are pulled into the binding portion side The cotton layer and the urethane foam layer are compressed by sandwiching the upper and lower fabrics to the center in the vertical direction, and the outer layer is convex outward due to the reaction force of both the cotton layer and the urethane foam layer that resists the compression. Provided with a mattress, wherein a plurality of bulge-shaped convex portions are located on the upper and lower surfaces of the futon, and the convex portions are juxtaposed via a valley-shaped portion located on a line connecting adjacent binding portions Thus, the above problems are solved.

  According to the present invention, it is possible to obtain a mattress which has a simple structure and is provided with a plurality of convex portions arranged in parallel with each other without increasing the manufacturing cost. In addition, since the cotton layer is located under the fabric and the urethane foam layer is located underneath it, the rebound from each convex part to the body side is reduced when taking a sleeping posture, and the cotton layer The softness makes the touch feel and the urethane foam layer does not give a feeling of bottoming, and provides good sleeping comfort.

Next, the present invention will be described in detail based on the illustrated embodiment.
In the figure, reference numeral 1 is a mattress, and in the mattress 1, as shown in FIG. 3, a urethane foam layer 4, and a cotton layer 3 are stacked in this order. As described above, the filler 5 is obtained by sandwiching the urethane foam layer 4 between the upper and lower cotton layers 3 in a sandwich shape. The urethane foam layer 4 has a constant thickness. Is provided so as to be constant, and the basic thickness of the filling 5 itself is set to be substantially constant. Further, the cotton layer 3 is made of polyester cotton, and the polyester cotton is put in an inner bag 6 having good air permeability for easy handling. The inner bag 6 is not necessarily required.

In the main mattress 1 in which the filling 5 is disposed between the upper and lower fabrics 2, the binding portions 7 are provided at the same position on the upper and lower surfaces of the futon and at substantially equal intervals. Each of the binding portions 7 is formed in a dot shape in a state in which the upper and lower fabrics are bound with a thread penetrating in the thickness direction of the duvet so that the upper and lower fabrics are viewed. FIG. 2 (a) shows a state during the production of the mattress 1, and FIG. 2 (b) shows a state in which the binding portion 7 is provided at the same position as (a). By providing this binding portion 7, A plurality of bulge-shaped convex portions 8 that are convex outward are formed on the upper and lower surfaces of the futon.
As for the convex part 8, the cotton layer 3 and the urethane foam layer 4 are compressed by the pinching by the upper and lower fabrics 2 to the center side in the futon thickness direction accompanied by the pulling of the upper and lower fabrics 2 to the binding portion 7 side, Due to the reaction force F of both the cotton layer 3 and the urethane foam layer 4 that resists pressure, the bulging shape is convex outward as described above. Thus, each of the convex portions 8 is in a state in which a reaction force is generated outwardly in the cotton layer 3 and the urethane foam layer 4, so that the reaction force is generated only when the body is put on the conventional one. Compared with the feeling of bottoming out, the cotton layer 3 is located on the side in contact with the body, so that the touching touch is a convex portion 8 where a soft touch is obtained.

Furthermore, the adjacent convex part 8 is arranged in parallel via the valley-shaped part 9 located on the line which connects the said adjacent binding part 7, The several convex part 8 was lined up closely, and the body which took the sleeping posture Is supported in a state where the body pressure is dispersed, so that a part of the body is prevented from falling excessively and floor rubbing is less likely to occur.
In addition, even if it exists in the binding part 7 and its circumference | surroundings, and the said valley-shaped part 9, it is a part in which the filler 5 is located, and it has produced reaction force toward the outside, and the body of a sleeping posture is fully It is a part that can be supported by.

It is explanatory drawing which shows the mattress concerning this invention. The cross section is shown. (A) is an explanatory view showing a state before the binding portion is provided, and (B) is an explanatory view showing the cross section showing the state where the binding portion is provided at the same position as (A).
