DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pillow provided with a cover body and a shape-retaining portion arranged inside the cover body for holding the cover body in a predetermined shape, and a mattress used with the pillow.

[0002]

2. Description of the Related Art There are cases where it is desired to change the height of a pillow to a desired height depending on personal preference and physical condition at that time, and various pillows corresponding to such needs have been proposed.
Such a pillow is configured such that the height can be changed by, for example, folding the pillow in two or three.

[0003]

The pillows described above are designed to adjust the height by folding the pillow itself.
The mounting area for the head is different between the unfolded state and the folded state, and when many are folded and raised, the inconvenience that the head comes off the pillow just by shifting the head a little while sleeping There was something to do. Further, when the pillow is used without being folded, the whole pillow becomes large and disadvantageous in handling. Further, it is difficult to finely adjust the height of the pillow, and it is inconvenient that the height cannot be finely adjusted.

[0004] Further, especially when the bedridden state is used, it is not possible to frequently dry the pillow or wash the pillow cover, which may lead to early generation of bad smell and mold.
There is no effective solution in this regard, and early improvement is demanded.

[0005] In view of the above situation, the present invention seeks to solve the problem. Even if the height is adjusted, there is no change in the mounting area on which the head is mounted, and fine adjustment can be performed. Another object of the present invention is to provide a pillow capable of avoiding the generation of bad odor and mold at an early stage.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention comprises a cover and a shape-retaining portion arranged inside the cover to hold the cover in a predetermined shape. In the pillow, the shape-retaining portion comprises a charcoal portion made of bincho charcoal, and a plurality of plate-like bodies formed to have substantially the same surface area in a vertical direction that can be stacked in the vertical direction, Each of the plate members is made of a material having air permeability. Therefore, by changing the number of plate-like bodies, the height (thickness in the vertical direction) of the pillow can be changed without changing the mounting area of the head on the cover. Moreover, since the pillow is a plate-like body, the height of the pillow can be finely adjusted. In addition, since each plate-shaped member can be made of a material having air permeability to enhance air permeability, not only can moisture not easily accumulate inside the cover, even if moisture accumulates In addition, the moisture can be absorbed by the charcoal portion, and the generation of bad odor and mold can be avoided. The charcoal is said to emit far-infrared rays, and can warm the human body. As the charcoal, since Bincho charcoal has hardness like iron, it is hard to be crushed by the weight of the head, and the above-mentioned effect can be exhibited well over a long period of time. The charcoal portion may be a single or plural charcoal such as a rectangular parallelepiped, a cubic, or a plate having a small thickness at the top and bottom, but a bag of a large number of charcoal pieces formed by pulverizing into granules. The use of the charcoal is advantageous in that the surface area of the charcoal can be dramatically increased, and the above effect can be enhanced.

[0007] By forming the plate-like body from a material having flexibility enough to be folded or rolled, not only the height can be partially increased but also the cushioning property for receiving the head can be enhanced. .

[0008] The charcoal portion is arranged below the plate-like body,
By arranging a metal film between the charcoal part and the bottom of the cover body, the cushioning property is optimized, while far infrared rays emitted from the charcoal are reflected to the head side to enhance the effect described above. Can be.

The cover body is a bag-like body having a substantially rectangular shape in a plan view, and the upper surface of the bag-like body is provided substantially at the center of the bag-like body in the short side direction and at both ends in the long side direction of the bag-like body. By forming an opening having a length that substantially extends over and attaching a hook-and-loop fastener for closing the opening to the edge of the opening, opening and closing operations of the opening can be performed faster than those that close the opening with buttons or fasteners. In addition to the above, even when the contents in the bag-like body are full, the hook-and-loop fasteners can be easily closed by slightly shifting the positions of the hook-and-loop fasteners.

[0010] A mattress used with the pillow, wherein an upper mat portion made of a gas-permeable material and a lower mat having a plurality of recesses formed on a surface for storing charcoal or other charcoal in a divided manner. The use of the mattress including the parts not only prevents the generation of bad odor and mold at an early stage as in the case of the pillow, but also exerts the effect of warming the body. In addition, by separating the charcoal, the charcoal can be prevented from moving and concentrating on a part when the mattress is moved.

[0011] The mattress is covered with a breathable cover, and a fixing means for fixing the pillow is provided at a specific position on the head side of the upper surface of the cover, so that fresh air is supplied to the mattress. By adopting the pillow, it is possible to further prevent the generation of offensive odor and mold, and the pillow does not move with respect to the mattress.
