FIG. 3 is a schematic side view showing a state in which the foldable mattress 1 according to the embodiment of the present invention is folded. In FIG. 3, the contents of the mattress 1 covered with the outer cover 10 are also indicated by broken lines in order to facilitate understanding. As shown in FIG. 3, the contents of the mattress 1 covered with the outer cover 10 can be bent at the connection piece 111. And the storage chamber 110 connected with the connection piece 111 can be piled up and down by this bending. As a result, as shown in FIG. 3, the mattress 1 can be folded in three.

The mattress 1 is provided with a plurality of storage bodies that are stacked in a separable manner inside each of the plurality of storage chambers 110. This will be described with reference to FIG. FIG. 4 is a schematic cross-sectional view at the position AA in FIG. In the present embodiment, the contents of the three storage chambers 110 included in the mattress 1 are all the same. For this reason, the content of one storage chamber 110 will be described as a representative, and the description of the content of the other storage chamber 110 will be omitted.

As shown in FIG. 4, in this embodiment, four storage bodies 12 to 15 are stored in each storage chamber 110. In detail, the four storage bodies 12 to 15 include a heat generating sheet 12, a first cushion body 13, a second cushion body 14, and a three-dimensional network structure 15. The four storage bodies 12 to 15 have substantially the same size in a plan view from the up and down direction. The four storage bodies 12 to 15 are separable from each other, and can be put into and out of the storage chamber 110 individually.

The exothermic sheet 12 has a hygroscopic exothermic fiber. The hygroscopic exothermic fiber can absorb moisture generated from the human body and bring about a heat generation effect. The hygroscopic exothermic fiber preferably has an antibacterial action and a deodorizing function. The hygroscopic exothermic fiber may be, for example, an acrylate fiber. More specifically, the hygroscopic exothermic fiber may be a breath thermometer manufactured by Mitsuno Corporation.

FIG. 5 is a schematic plan view of the exothermic sheet 12 provided in the foldable mattress 1 according to the embodiment of the present invention as viewed from above. As shown in FIG. 5, the exothermic sheet 12 is a sheet having a quilting structure in which a fiber material containing hygroscopic exothermic fibers is placed between two cloths and sewn. The fiber material sandwiched between the two sheets of cloth may be composed of only hygroscopic exothermic fibers, but in this embodiment, the hygroscopic exothermic fibers are mixed with other fiber materials. The other fiber material is not particularly limited, but may be, for example, polyester, nylon, acrylic, wool, cotton, or the like. The degree of heat generation of the exothermic sheet 12 can be adjusted by adjusting the mixing ratio of other fiber materials.

The first cushion body 13 is disposed under the exothermic sheet 12 in the present embodiment. The first cushion body 13 is made of solid cotton. In the present embodiment, the solid cotton constituting the first cushion body 13 is 100% polyester. However, the present invention is not limited to this. For example, wool or a mixture of polyester and wool may be used. . Moreover, the 1st cushion body 13 should just have cushioning properties, and may be comprised other than solid cotton. The first cushion body 13 may be made of a resin foam such as polyurethane foam.

The second cushion body 14 is disposed under the first cushion body 13 in the present embodiment. The second cushion body 14 is harder than the first cushion body 13. In the present embodiment, the second cushion body 14 is made of solid cotton like the first cushion body 13. However, the compression degree of the second cushion body 14 is larger than that of the first cushion body 13. The second cushion body 14 may have a cushioning property and be harder than the first cushion body 13 and may be formed of other than solid cotton.

The second cushion body 14 may be made of a resin foam such as polyurethane foam. For the second cushion body 14, for example, a highly elastic urethane foam having a hardness of 150 N or more in JIS K6400-2 (D method) can be used. For the first cushion body 13, for example, urethane foam having a hardness of 100 N or less in JIS K6400-2 (Method D) can be used. In addition, as shown in FIG. 11, the 1st cushion body 13 and the 2nd cushion body 14 may be joined so that it may mutually overlap with the adhesive agent 18. As shown in FIG.

Further, the first cushion body 13 and the second cushion body 14 may be made of a resin foam having the same hardness. In this case, as shown in FIG. By providing the groove 19, the first cushion body 13 can sink more easily than the second cushion body 14, that is, it can be formed softer. It is preferable to form the groove 19 so that the inner side swells and has a space because the groove 19 is more likely to sink when a compression load is applied to the first cushion body 13.

The three-dimensional network structure 15 is disposed under the second cushion body 14 in the present embodiment. The three-dimensional network structure 15 is made of a resin material and has higher air permeability than the first cushion body 13 and the second cushion body 14. The three-dimensional network structure 15 preferably has a cushioning property. The three-dimensional network structure 15 preferably has water permeability. The three-dimensional network structure 15 may be, for example, a polyether ester fiber. More specifically, the three-dimensional network structure 15 may be, for example, Breath Air (registered trademark) manufactured by Toyobo Co., Ltd.

The user of the mattress 1 of the present embodiment or an assistant thereof takes out or stores the four storage bodies 12 to 15 individually or collectively in the storage chambers 110 from the storage chamber 110. It can be put in the chamber 110. In addition, since the four storage bodies 12 to 15 are separable from each other, the above-described user or caregiver can appropriately change the stacking order thereof. In some cases, any one or more of the four storage bodies 12 to 15 can be changed to a configuration in which the storage chamber 110 is removed.

For example, when the user desires to warm the surface of the mattress 1, a configuration in which the exothermic sheet 12 is arranged at the top as in the present embodiment is effective. Further, for example, when the user desires the hard mattress 1, the first cushion body 13 and the second cushion body 14 can be exchanged up and down from the configuration of the present embodiment. Or it is good also as a structure by which the 2nd cushion body 14 is arrange | positioned on the top.

Also, even the same user may have different preferences depending on the season. For example, the user has a desire that a mattress that feels warm in winter is good and a mattress that feels cool in summer. The configuration of the present embodiment is suitable for use in winter because the exothermic sheet 12 is on the top. In summer, for example, the positions of the exothermic sheet 12 and the three-dimensional network structure 15 may be interchanged from the configuration of the present embodiment. Thereby, it can change to the mattress which can feel coolness. In some cases, the mattress 1 may be turned upside down without changing the stacking order of the plurality of storage units stored in the storage chamber 110 from the configuration of the present embodiment. Also in this case, since the three-dimensional network structure 15 is arranged on the top, the user can feel cool in the summer.

Further, the mattress 1 of the present embodiment can change the stacking order of the four storage bodies 12 to 15 for each storage chamber 110. For this reason, for example, when the user desires to warm only the position of the foot, one or two storage chambers 110 on the leg side are configured in this embodiment, and the other storage chambers 110 generate heat. It is also possible to make the heat-sensitive sheet 12 second or higher from the top, or to remove the heat-generating sheet 12 in some cases. Further, it is possible to cope with a user's desire to make only the waist position hard by appropriately determining the stacking order of the storage bodies 12 to 15 for each storage chamber 110.

In addition, the mattress 1 of the present embodiment can be replaced by extracting only a part of the storage body from the storage chamber 110. For this purpose, for example, it is possible to replace only an old storage body with a new one. Further, according to the mattress 1 of the present embodiment, only a part of the dirty storage body can be washed or replaced with a new one.

In the present embodiment, the exothermic sheet 12 is provided to be thinner than the first cushion body 13 and the second cushion body 14 (see FIG. 4). In general, a sheet having a small thickness is likely to cause a lateral shift or be folded. In this regard, in this embodiment, the friction coefficient between the heat generating sheet 12 and the inner cover 11 is smaller than the friction coefficient between the heat generating sheet 12 and the first cushion body 13. For this reason, even if the inner cover 11 moves, the exothermic sheet 12 is less likely to cause lateral displacement with respect to the first cushion body 13 and is also less likely to be folded. In addition, when the exothermic sheet 12 is taken in and out of the storage chamber 110, the exothermic sheet 12 can be smoothly put in and out because the exothermic sheet 12 has good sliding properties with respect to the inner cover 11.

In the present embodiment, the friction coefficient between the exothermic sheet 12 and the inner cover 11 is smaller than the friction coefficient between the exothermic sheet 12 and the second cushion body 14. In the present embodiment, the friction coefficient relationship described above is realized by using the inner cover 11 as a mesh cover.

In the present embodiment, the four storage bodies 12 to 15 can be taken out from the inner cover 11, and the four storage bodies 12 to 15 can be separated apart. For this reason, the mattress 1 of this embodiment is excellent in transportability.

The embodiment described above is merely an example of the present invention. The configuration of the embodiment described above may be changed as appropriate without departing from the technical idea of the present invention. Moreover, the structure of the modification shown multiple may be combined in the possible range.

For example, in the embodiment described above, the number of the storage chambers 110 provided in the inner cover 11 is four, but the number is not limited to three as long as it is plural.

In the embodiment described above, the storage bodies that are put in the respective storage chambers 110 are, in principle, the exothermic sheet 12, the first cushion body 13, the second cushion body 14, and the three-dimensional network structure 15. However, the number may be changed as appropriate according to the user's preference. The number of storage bodies stored in the storage chamber 110 may be less than the above four or may be increased depending on user preference.

In the embodiment described above, the first cushion body 13, the second cushion body 14, and the three-dimensional network structure 15 are directly stored in the storage chamber 110 without being covered with a cover. However, this is only an example. At least one of the first cushion body 13, the second cushion body 14, and the three-dimensional network structure 15 may be covered with the individual cover 16 and stored in the storage chamber 110.

FIG. 6 is a schematic cross-sectional view for explaining the configuration of a foldable mattress according to another embodiment of the present invention. In the configuration shown in FIG. 6, the first cushion body 13, the second cushion body 14, and the three-dimensional network structure 15 are all covered with the individual cover 16 and stored in the storage chamber 110. Since each of the storage bodies 13 to 15 is covered by the individual cover 16, it is possible to make the storage bodies 13 to 15 less likely to lose shape during use.

The individual cover 16 is preferably a mesh cover in consideration of air permeability and the like. Similar to the outer cover 10 and the inner cover 11, the individual cover 16 is preferably configured so that the opening can be opened and closed by an opening and closing tool such as a fastener. The material used for the individual cover 16 may be the same for any type of storage body, but may be changed according to the type of the storage body. Each individual cover 16 may be configured to have a different friction coefficient in accordance with the type of storage body stored therein.

In the configuration shown in FIG. 6, all of the first cushion body 13, the second cushion body 14, and the three-dimensional network structure 15 are housed in the individual cover 16, but any one of these, or Only two of them may be stored in the individual cover 16. For example, only the three-dimensional network structure 15 that is likely to lose its shape may be stored in the individual cover 16.

In FIG. 7, the three-dimensional network structure 15 is covered with the individual cover 16 and stored in the storage chamber 110, and the first cushion body 13 and the second cushion body 14 overlap the third cover 17. The embodiment accommodated in the storage chamber 110 in the state accommodated by the is shown. As described above, the first cushion body 13 and the second cushion body 14 are accommodated on the third cover 17 so that the user can perform the first cushion body 13 and the second cushion body in one operation. The third cover 17 storing 14 can be stored in the inner cover 11. Therefore, the operation can be simplified as compared with the case where the user separately stores the first cushion body 13 and the second cushion body 14 in the inner cover 11.

Also, as shown in FIGS. 10B and 10C, the user switches the stacking order of the first cushion body 13 and the second cushion body 14 in accordance with the preference of the hardness of the upper surface of his mattress. At this time, the first cushion body 13 and the second cushion body 14 are simply stacked upside down while the first cushion body 13 and the second cushion body 14 are stored in the third cover 17. The order can be changed.

FIG. 8 is a view showing an aspect of the third cover 17 in which the first cushion body 13 and the second cushion body 14 are accommodated, and FIG. 9 is a top view of the third cover 17 of FIG. It is a figure which shows a state. As shown in FIGS. 8 and 9, the third cover 17 is formed in a mode in which colors or patterns are different between the outer surface on the first cushion body 13 side and the outer surface on the second cushion body 14 side. . By forming in this way, which surface is the first cushion body without directly confirming the first cushion body 13 and the second cushion body 14 housed in the third cover 17. Therefore, the hardness of the upper surface of the mattress can be easily and definitely changed.

In the present embodiment, the third cover 17 is a cloth mesh cover. Thereby, air permeability etc. can be ensured, for example. However, this is merely an example, and the structure and material of the third cover 17 may be changed as appropriate. The third cover 17 preferably has a smaller frictional force against the inner cover 11 and the heat generating sheet than the surfaces of the first cushion body 13 and the second cushion body 14. As a result, when the first cushion body 13 and the second cushion body 14 are stored in the third cover 17, they can be stored more smoothly when stored in the inner cover 11. The third cover 17 is preferably configured so that the opening can be opened and closed by an opening and closing tool such as a fastener.
