Description

[Detailed Description of the Invention] The present invention relates to the improvement of futons, and in particular, an object of the present invention is to provide a futon that can be used as a pinerest and has an acupressure effect.

Conventionally, when using a pinerest for sleeping, a cotton-filled pad or a cotton mattress was placed on top of the pinerest, and when using a pad with an acupressure effect, the pad was placed on top of a futon. Apart from this, it was placed on top of or under the futon.

Therefore, it takes time and effort before going to bed, and there is a risk that the futon and the mattress or the futon and the pad may become misaligned while sleeping, which has the disadvantage that a comfortable sleep is likely to be disturbed.

Furthermore, although people sweat a lot while sleeping, few conventional futons have been designed with regard to breathability, resulting in the problem of uncomfortable sleeping conditions.

The present invention solves the above-mentioned drawbacks of the prior art and will be described below based on embodiments shown in the accompanying drawings.

1 is a cover made of ordinary fabric such as cotton,
The interior of the cover 1 is divided into upper and lower spaces by an inner cover 1'.

The upper space of the cover 1 is filled with sweat-absorbent cotton 2 made of polyester or the like at a rate of about 200 g/cm ³ to 300 g/cm ³ , and the upper surface of the cover 1 is quilted to form multiple upper spaces. It is divided into.

3 is a core material filled in the lower space of the cover 1, and a cushioning material 4, a porous material 5, and an auxiliary material 6 are appropriately bonded and laminated in this order.

The cushioning material 4 is made of soft urethane foam with a specific gravity of 0.017 to 0.030, has a thickness of 40 to 60 mm, and a width of 40 to 60 mm.
It is best to have a plate shape of 900 to 1300 mm and a length of 1900 to 2300 mm, with a profiled top surface.
It has a continuous uneven pattern.

The porous material 5 is made of soft urethane foam with a specific gravity of 0.04 to 0.12, which is higher than that of the cushioning material 4.
The outer periphery has the same shape as the cushioning material 4. The porous material 5 is provided with a large number of vertically spaced holes 7 having diameters of 60 to 90 mm and substantially equally spaced over the entire surface thereof.

Appropriate holes 7 near the longitudinal center of the porous material 5
A hemispherical pad 8 is fitted so that its spherical surface slightly protrudes from the upper surface of the porous material 5 and its bottom surface is aligned with the lower surface of the porous material 5. In addition, the pad 8
It is preferable that the hole is made of a synthetic resin or synthetic rubber having a higher specific gravity than the cushioning material 4, and its diameter is slightly larger than the hole 7.

The auxiliary material 6 is made of soft urethane foam with a specific gravity of 0.02 to 0.03, and its outer shape is the same as that of the cushioning material 4.
and has the same shape as the porous material 5.

The core material 3 made up of the above three members is covered with a coarse knitted fabric 9 that is slightly larger than the core material 3, and the cover 1
The lower space of the cover 1 is filled so as to be freely accessible through an opening of the cover 1 (not shown). Note that a chuck or the like is attached to the opening, so that the core material 3 is shielded from the outside air during use.

In this embodiment, the porous material 5 is made of soft urethane foam with a high specific gravity and has a large repulsive force. Therefore, when a person lies down on the futon that can also be used as a pinerest of the present invention, the body does not sink down more than necessary, reducing fatigue when sleeping. Does not occur. In addition, since the porous material 5 has a large number of holes 7, it is easy to elastically deform when weight is applied, and since there is also a gap 10 between the pad 8 and the hemispherical pad 8, the elastic deformation is prevented. It is not obstructed by the cushioning and can exhibit appropriate cushioning properties.

Since the upper surface of the cushioning material 4 is profiled, it has good breathability and prevents sweat from accumulating, and also has good heat retention due to the formation of an air layer. In addition, the cushioning material 4, the porous material 5, and the auxiliary material 6 are all made of soft urethane foam having an open cell structure, so that they have good sweat absorption properties.

Since the present invention is configured as described above, the following effects are produced.

First, because the core material that functions as a pinerest is covered with a cover that functions as a futon, and the two are integrated, it has the functions of both a pinerest and a futon, and therefore, the pinerest and futon are separate from each other as in the past. It also saves you the trouble of laying each one separately. Furthermore, the present invention has the advantage that only the cover can be taken out and washed (conventional futons cannot be washed).

Secondly, since the pad made of a synthetic resin foam with a high specific gravity is provided so that the upper part protrudes, an acupressure effect can be expected, and since the position of the pad is fixed, a certain point is always pressed.

Thirdly, since the pad is fitted into an appropriate hole in the longitudinal center of the porous material, the pad is placed at the waist where the load is most likely to be concentrated, and as a result, the waist can be prevented from sinking. You can enjoy a comfortable night's sleep without feeling tired.

Fourth, since the porous material has many holes, it is easy to elastically deform when weight is applied, and it can exhibit appropriate cushioning properties. The presence of holes further improves breathability. Furthermore, since an air layer is formed within the pores, it has excellent heat insulation and heat retention properties.

Furthermore, since the upper surface of the cushioning material has a continuous pattern of concave and convex patterns, it has good breathability and prevents sweat from accumulating, and an air layer is formed to provide good heat retention.
