BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a mattress in which the cotton in the futon blanket is made into a plurality of blocks, and each cotton block can be washed individually, and in particular, each cotton block can be easily washed from the futon blanket. Regarding the technology that allows you to take in and out.

[0002]

BACKGROUND OF THE INVENTION Conventionally, as disclosed in, for example, Japanese Utility Model Publication No. 4-11565, it is already known that cotton in a blanket is made up of a plurality of blocks and each of the cotton blocks is individually washed. . This idea of dividing the filling cotton into multiple pieces creates the advantage that the filling cotton can be partially washed. Therefore, the effect is particularly remarkable when it is applied not only to the general public, but also to a futon such as a sick person or an infant.

[0003] However, in the technique disclosed in that publication, ordinary cotton which is easy to come loose is used as the cotton block, and tie stitches are required to prevent the cotton from coming loose. Moreover, probably because the cotton block itself can be bent, the content cotton is only divided into a plurality in a direction orthogonal to the longitudinal direction of the mattress. On the other hand, it is said that it is good for your health to use a firm mattress when you go to bed. As a cotton material for such a solid mattress, a synthetic fiber has been developed. This solid material is obtained by, for example, mixing two kinds of synthetic fibers having different melting points, melting one material having a lower melting point with heat, and molding the whole into a futon shape.

The inventor has paid attention to the fact that the solid material does not lose its shape even when it is washed by washing with water, and considered to apply the idea of blocking to the mattress composed of the solid material. As a result of various investigations, it was found that the hard block does not easily lose its shape, but cannot be freely deformed, and thus it is difficult to put it in and out of the blanket.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above points, and an object thereof is to provide a mattress in which a plurality of solid blocks can be easily put in and taken out of a mattress. To do. Another object of the present invention is to provide a mattress that can be folded and is convenient for storage.

[0006]

[Means and Actions Therefor] The mattress according to the present invention is basically configured such that not only one mattress is divided in the longitudinal direction but also the mat is divided into right and left. To be a little more specific, the futon of this invention is a futon made up of a solid block in a futon that can be inserted and removed freely.
A. There are n (3) duvets in the longitudinal direction of the mattress.
≦ n ≦ 7), and 2n solid block storage chambers divided into two left and right, B. Moreover, the futon kawa is provided with openings on both sides thereof, and the hard block can be inserted into and taken out from the solid block storage chamber facing the opening through the openings. By dividing into the right and left, each solid block becomes small, and in combination with the openings on the left and right, each solid block can be easily put in and taken out. If the opening is provided with a simple opening / closing means such as a fastener, the opening / closing becomes easier.
The number of divisions depends on the use for adults, children, etc., but usually 3 to 7 in the longitudinal direction, 2 in the left and right, and considering the size when folded, Five, two on the left and right are optimal.

Further, it is preferable that each solid block has the same shape in consideration of preparation of a molding die. As an actual shape, a rectangular parallelepiped whose plane shape is a quadrangle, or a trapezoidal plane shape can be used. If the planar shape is a trapezoid, the tip end portion to be put in and taken out becomes a taper shape although it is slightly, so that it can be put in and out more easily. In addition, in the case of the trapezoid, the pair of left and right contact areas becomes larger, probably because the pair of left and right parts are more integrated in the blanket blanket, which is excellent in folding.

[First Embodiment] FIGS. 1 to 3 show a mattress 100 according to a first embodiment, FIG. 1 is a plan view, and FIG. 2 is 2-2 'of FIG.
Sectional drawing which follows the line, FIG. 3 is a side view. Mattress 100
Is composed of a futon and a solid pad inside. The futon waft is divided into 5 pieces vertically and 2 pieces left and right along the longitudinal direction.
1b, 22a, 22b, 23a, 23b, 24a, 24
b, 25a, 25b. Each of the solid block storage chambers has a box (rectangular parallelepiped) shape, and the solid block 30 is inserted therein. In order to define such a solid block storage chamber in the bedding blanket, side gusset cloths 130 on both sides and a central partition cloth 140 are sewn between the front cloth 110 and the back cloth 120. Then, a pair of left and right solid block storage chambers 21a, 21b, 22a, 2
2b, 23a, 23b, 24a, 24b, 25a, 25
In b, an opening 50 is provided on the side surface by a fastener. The partition 140 at the center is particularly effective in arranging the solid block 30 therein in a stable state.
However, in some cases, the partition 140 may be omitted.

The solid block 30 entering each accommodation chamber is constructed by covering the surface of a synthetic resin molded product with a net-shaped inner bag. The solid block 30 fits the size of each accommodation chamber and can be easily put in and taken out through the opening 50.
These solid blocks 30 can be washed entirely or in part as appropriate.
In addition, the mattress 100 includes a pair of left and right storage chambers 21a, 2a.
1b; 22a, 22b; 23a, 23b; 24a, 24
b; 25a, 25b and the pair of solid blocks 30 contained therein can be integrated into one and folded in five.
The five-fold mattress 100 can be compactly stored in a box-type casing, which is very convenient for storage.

[0010]

[Second Embodiment] In the first embodiment, the solid block 3 is used.
Although 0 is a rectangular parallelepiped having a square planar shape, the mattress 200 of the second embodiment shown in FIGS. 4 and 5 uses a solid block 300 having a trapezoidal planar shape. The solid blocks 300 all have the same shape, and when the right and left pairs are assembled together, they have a horizontally long rectangular parallelepiped shape.
4 and 5 use a solid block 300 having the same shape, a pair of left and right solid blocks 30 in FIG. 4 is used.
The zero mating portions 310 run zigzag when viewed in the longitudinal direction of the mattress 200, while all the mating portions 310 are arranged in parallel in FIG. In the second embodiment, one end of each solid block 300 has a tapered shape, which is advantageous in that it can be easily taken in and out, and because the area of the mating portion 310 is large, a pair of left and right solid blocks 300 is more likely to be formed. There is an advantage that they are integrated with each other, and further, there is an advantage that the fitting portion 310 is less likely to cause discomfort because the fitting portion 310 is widely distributed on the back of a person.

As can be seen from the embodiments shown in the drawings, the mating portions 310 of the pair of left and right rigid blocks 30, 300 are normally set vertically, but in some cases,
The mating portion 300 may be slightly tapered.

[0012]

[Effects of the Invention] In this invention, not only one sheet of mattress is divided in the longitudinal direction, but also one sheet of mat is divided into left and right parts. Therefore, the advantage of washing the contents can be utilized more effectively. In particular, a solid block having a trapezoidal planar shape is easier to put in and take out, and is also excellent in sleeping comfort and storage.
