Abstract

PROBLEM TO BE SOLVED: To improve heat retaining property by mounting an inner back cloth between a front cloth and a back cloth and housing plural pieces of inner cotton having different length in the horizontal direction between the front cloth, the inner back cloth and the inner back cloth, the back cloth so as to raise the height of the inner cotton at a center part where a person lies down. SOLUTION: An inner back cloth 2 is mounted between a front cloth 1 and a back cloth and a mattress half body 4 housing first and second inner cotton 3a and 3b is fixed in a bag-like body made of the front cloth 1 and the inner back cloth 2 by overlapping a nonwoven fabric. At this time, the first inner cotton 3a is housed extending over the whole in the horizontal direction and the second inner cotton 3b is housed only in a center part in the longitudinal direction to raise the center part in the longitudinal direction. Thereby, excellent heat retaining property and cushion property are obtained and since the mattress becomes nearly flat in the state that a person lies, a sleep feeling is improved and the wear of the mattress is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mattress that improves heat insulation and cushioning properties and makes it difficult for the mattress to sag.

[0002]

2. Description of the Related Art Hitherto, in order to improve the heat retaining property and cushioning property of a mattress, various measures have been taken to accommodate a large amount of batting.

[0003]

However, the use of a large amount of batting has the disadvantage of increasing the cost. In addition, the conventional mattress evenly filled with batting has a problem in that when the human body lies down, the center sinks under the weight of the human body, and as a result, the mattress tends to settle.

[0004] The present invention is intended to solve such a problem, and provides a mattress in which heat insulation and cushioning properties are improved without increasing the amount of batting, and sagging of the mattress is hardly caused. That is its purpose.

[0006]

Means for Solving the Problems In order to achieve the above-mentioned object, the present inventors have made intensive studies and found that, in the case of batting of the same thickness, laminating a plurality of batting improves heat insulation. Attention has been paid, and furthermore, it has been found that the heat retaining property is further improved by interposing a middle lining between the battings, and the present invention has been achieved.

That is, according to the present invention, a middle lining is attached between a surface material and a lining, and a plurality of battings having different lateral lengths are accommodated between the surface material and the middle lining, and between the middle lining and the lining. It is characterized by raising the height of the batting in the center where humans lie down.

In the present invention, a part of the batting is accommodated only in the central part where the person lies, so that the central part in the length direction of the mattress is convex. When a person lays on the mattress, the mattress becomes almost flat, so that the cushioning property and the sleeping comfort are excellent, and the mattress hardly sags.

The present invention is characterized in that a middle lining is interposed between a surface material and a lining, but a mattress having such a middle lining is not commercially available. No idea is known.

[0010]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view showing an embodiment of the present invention, in which a futon half in which a first batting 3a and a second batting 3b are accommodated in a bag-like body formed of a surface material 1 and a middle lining 2. 4 and 4 show an example in which nonwoven fabrics 2 and 2 are overlapped and fixed.

The first batting 3a is accommodated in the entire lateral direction, while the second batting 3b is accommodated only in the central portion in the longitudinal direction. Therefore, although not shown in FIG. 1, the central portion is actually a slightly convex mountain shape.

The first batting 3a and the second batting 3b are preferably accommodated so that the first batting 3a is in contact with the outer material 1, since the surface becomes smoother, but they may be reversed. .

The futon containing the batting as described above is shown in FIG.
As shown in FIG. Since the wave stitch extends from the front surface to the back surface, the batting is firmly fixed.

By using the wave stitching, the batting can be firmly fixed as compared with the case where the sewing is performed linearly. A similar effect can be obtained if the sewing is performed in a curved shape without using the wave sewing.

In the above embodiment, the inner linings 2, 2 are formed of a nonwoven fabric. This need not be the case, but by using a nonwoven fabric, the batting can be prevented from shifting, and can be fixed more firmly, and the mold can be less likely to break when washed.

The outer periphery of the junction between the futon halves 4 and 4 may be subjected to a helicopter process for sewing a common fabric in order to improve the appearance.

In the above embodiment, the two futon halves 4 and 4 are combined to form a single mattress.
The inner lining 2 may be formed as one sheet and may be directly formed into the structure shown in FIG.

The material of the batting 3a, 3b used in the present invention is not particularly limited. However, it is preferable to use chemical fibers such as polyester since it can be easily washed.

According to the present invention, since the middle lining is interposed in the middle portion and the batting is stored in a plurality of layers, the heat retaining property is remarkably improved as compared with the case where the batting is housed at the same thickness.

Further, since the second batting 3b is accommodated only in the central part where the person lies, an air layer is formed in the futon, and therefore, the heat retaining property is also improved.

Further, by storing the second batting 3b only in the central portion, the cushioning property is improved, and in the lying state, it becomes almost flat, so that the sleeping comfort is improved.

Even if battings having different lengths are accommodated in this way, by disposing a nonwoven fabric in the middle and sewing in a curved shape, it is possible to effectively prevent the batting from shifting.

[0023]

As described above, according to the present invention, excellent heat insulation and cushioning properties can be obtained without increasing the amount of batting, and the human body can be laid down. Since it is substantially flat, it is excellent in sleeping comfort, and has many advantages such as setting of the mattress less easily.
