DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mattress having a structure in which a plurality of mattress pieces are accommodated in a cover so as to be suitable for use in a hospital or a nursing home.

[0002]

2. Description of the Related Art Conventional mattress-type mattresses are one-piece, so they have a large shape and a large weight. For this reason, the replacement work requires a great deal of labor and time, has a drawback of putting a heavy burden on the operator, a drawback of requiring a large storage space, and a drawback of requiring a large cleaning device and a drying device. is there. Therefore, the inventor of the present application has previously proposed an invention of a mattress for a mattress that can be used in the same manner as a single sheet by dividing a mattress into a plurality of mattress pieces and integrally storing the mattress pieces in a cover ( Japanese Patent Application No. 9-309905).

[0003] The above-mentioned mattress is formed by defining three mattress piece accommodating portions on the basis of one bottom cloth so that the mattress piece can be folded in three in a state of being accommodated therein.
It can be replaced, transported, washed, and dried separately for each mattress piece, so it is excellent in workability, and since only dirty mattress pieces can be replaced, it is economical and has many excellent features. Have

[0004]

By the way, a plurality of partition walls are formed on the cover to accommodate three or more mattress pieces in a foldable manner. In order to be foldable, at least one partition wall must be formed so as to be in a mountain-folded state when the mattress-type mattress is unfolded, and to be in a flat-extended state when folded. For this reason, the partition wall is formed in an upright state. However, the partition wall hits the back of the user, giving a sense of incongruity or rubbing during use. Therefore, some solution has been desired.

The present invention has been made in view of the above-mentioned problems of the prior art, and can store three or more mattress pieces in a freely foldable manner. In addition, the partition wall hits the back during use, causing discomfort to the user or rubbing. It is an object of the present invention to provide a mattress that does not slip and does not shift even when used on a movable bed.

[0006]

According to the present invention, there is provided a mattress body composed of three or more rectangular mattress pieces, and the mattress body is foldable. A mattress-type mattress comprising a cover to be stored, wherein the cover is arranged by longitudinally arranging a plurality of mattress piece receiving portions for storing each of the three or more mattress pieces, and folding the crests and valleys. A plurality of mattress piece accommodating portions are configured to be foldable, and at least a pair of mattress piece accommodating portions of the plurality of mattress piece accommodating portions define a pair of wall pieces that are valley-folded at an upper edge. Is formed by forming a horizontally long cutout in the vertical direction from the upper edge except for both ends in the longitudinal direction.

[0007] The mattress piece may be formed so that the thickness at both ends in the width direction is thinner than the center side, and the holding pieces provided in the mattress piece housing portion are locked at the both ends. Thus, the mattress pieces are securely accommodated in the cover without being displaced, and the mattress pieces can be easily inserted into and removed from the cover. Moreover, since the center side has a thickness, the cushioning property of the mattress is not lost.

The cover may be detachably mounted on the mattress body. By doing this, you can replace only the cover or only the mattress body,
Cleaning can be performed, work waste can be reduced, and the service life of the product can be extended.

[0009] Further, the cover has at least one of a back surface.
It is good to provide a non-slip material in the part. This can prevent the mattress from shifting when the movable bed is operated.

[0020]

The present invention has the following advantages because it is constructed as described above. (1) The mattress body is composed of mattress pieces divided into three or more pieces so that only the dirty or deteriorated mattress pieces can be replaced, which is economical. (2) Since the mattress body is composed of three or more divided mattress pieces, operations such as replacement, transportation, washing, and drying can be easily performed, so the workability is excellent and the burden on the operator is reduced. And it has excellent storage. (3) A pair of partition wall pieces defining a cover and defining at least a pair of mattress piece accommodating portions and being valley-folded at an upper edge are provided with notches having a laterally long notch at an upper edge side, excluding both longitudinal ends. Since the partition wall piece is formed, the partition wall piece does not hit the back of the user to give a feeling of discomfort while sleeping, and it does not cause rubbing and bedsores, and can be used with confidence. (4) The thickness of the mattress pieces at both ends in the width direction is made thinner than that at the center, and the holding pieces provided in the mattress piece receiving portion are locked to the both ends, so that the cover comes off from the mattress pieces. The mattress piece can be easily housed without any trouble, and the mattress piece can be easily inserted into and removed from the cover. Moreover, since the center side is thick, the cushioning properties of the mattress are not lost. (5) Since the cover is detachably mounted on the mattress main body, only the cover or only the mattress main body can be exchanged or cleaned, and work waste can be reduced and the service life of the product can be extended. be able to. (6) Since the non-slip material is provided on at least a part of the back surface of the cover, even when the mattress is used on a movable bed, there is no displacement and the stability in use is excellent.
