[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0011] In FIG. 1, reference numeral 1 denotes a fluid pillow according to the present invention.

[0012] This fluid pillow 1 has an upper bag body 2 in which a liquid (first fluid), for example, water, is sealed, and a lower bag body 3 in which a gas (second fluid), for example, air, is sealed.

[0013] As shown in Figures 2 to 4, the upper bag body 2 has a roughly rectangular bag body 4 on which the head P rests, a right attachment piece 5 extending to the right side of the bag body 4, and a left attachment piece 6 extending to the left side of the bag body 4.

[0014] A valve 7 for letting water in and out is attached to the bottom surface of the bag body 4.

[0015] The bag body 4 also contains a first elastic body 9 that is made of, for example, a sponge and has a substantially rectangular shape.

[0016] The first elastic body 9 has round holes 10 drilled through it at the four corners, and elongated holes 11 drilled through it between the round holes 10.

[0017] As also shown in Figure 5, the first elastic body 9 is fixed in a slack state to the bag body 4 by fastening snaps (first preventing means) 12 provided on the upper and lower sides of the interior of the bag body 4 through the round holes 10 and the long holes 11.

[0018] Moreover, water is sealed in the bag body 4 in a slack state.

[0019] As shown in FIG. 6, the snap 12 is composed of a protruding member 13, a recessed member 14 that fits into the protruding member, and a seal 15 that covers these.

[0020] As also shown in Figures 7 to 9, the lower bag body 3 has a right bag portion 21 arranged on the right side of the lower bag body 3, a left bag portion 22 arranged on the left side of the lower bag body 3, and a communicating portion 23 that connects the right bag portion 21 and the left bag portion 22.

[0021] This communicating portion 23 has a central bag portion 24 arranged below the bag main body 4 of the upper bag body 2, a right communicating portion 25 that communicates this central bag portion 24 with the right bag portion 21, and a left communicating portion 26 that communicates between the central bag portion 24 and the left bag portion 22.

[0022] The right bag portion 21, the left bag portion 22 and the central bag portion 24 each have a second elastic body 27 built in that is different from the first elastic body 9 and is made of, for example, urethane foam, and this second elastic body 27 is configured to have a right elastic body 28 built in the right bag portion 21, a left elastic body 29 built in the left bag portion 22, and a central elastic body 30 built in the central bag portion 24.

[0023] That is, the right bag portion 21 has an upper side and a lower side fixed together to form a right partition portion (second preventing means) 31 extending in the left-right direction, and the right elastic body 28 is housed in the portion partitioned by this right partition portion 31.

[0024] In addition, the left bag portion 22 has an upper side and a lower side fixed together to form a left partition portion (second blocking means) 32 extending in the left-right direction, and the left elastic body 29 is housed in the portion partitioned by this left partition portion 32.

[0025] Furthermore, the central bag portion 24 has an upper surface and a lower surface fixed together to form a central partition portion (second preventing means) 33 extending in the left-right direction, and the central elastic body 30 is housed in the portion partitioned by this central partition portion 33.

[0026] The right elastic body 28, the left elastic body 29 and the central elastic body 30 have rectangular holes 34 formed therein.

[0027] Furthermore, a valve 35 for letting air in and out is attached to the upper surface of the central bag portion 24.

[0028] Furthermore, the upper bag body 2 and the lower bag body 3 are provided with a first hook-and-loop fastener (first joining means) 41 that joins the upper bag body 2 and the lower bag body 3 in a detachable manner.

[0029] That is, one of a pair of first hook-and-loop fasteners 41 is attached to the lower surface of the bag body 4 of the upper bag body 2, the lower surface of the right mounting piece 5 and the lower surface of the left mounting piece 6.

[0030] Further, the other of the pair of first hook-and-loop fasteners 41 is attached to the upper surface of the central bag portion 24, the upper surface of the right bag portion 21 and the upper surface of the left bag portion 22 of the lower bag body 3.

[0031] Furthermore, a second hook-and-loop fastener (second joining means) 42 is provided which detachably joins the central bag portion 24 of the lower bag body 3 to the right bag portion 21 and also detachably joins the central bag portion 24 of the lower bag body 3 to the left bag portion 22.

[0032] That is, one of the pair of second hook-and-loop fasteners 42 is attached to the underside of the central bag portion 24, and the other of the pair of second hook-and-loop fasteners 42 is attached to the underside of the right bag portion 21 and the underside of the left bag portion 22.

[0033] During use, water is sealed in the upper bag body 2 in a loose state, and air is sealed in the lower bag body 3 in a loose state.

[0034] Additionally, the upper bag body 2 and the lower bag body 3 are joined together by a first hook-and-loop fastener 41 .

[0035] Furthermore, the right bag portion 21 of the lower bag body 3 is folded back at the right communicating portion 25 and disposed below and to the right of the central bag portion 24 and joined with a second hook-and-loop fastener 42 .

[0036] Furthermore, the left bag portion 22 of the lower bag body 3 is folded back at the left communicating portion 26 and disposed below and to the left of the central bag portion 24 and joined with a second hook-and-loop fastener 42 .

[0037] According to the above configuration, when the head P is placed on the center of the fluid pillow 1 and the user lies on his / her back, the center of the fluid pillow 1 sinks and the right and left sides rise, as shown in FIG.

[0038] As a result, a buoyancy force corresponding to the difference in water head between the right or left side and the center acts on the head P, allowing a comfortable sleep.

[0039] Also, as shown in FIG. 11, when one lies on his / her right side, the right side of the fluid pillow 1 sinks and the left side rises.

[0040] At this time, the height of the head P is higher when lying on one's side than when lying on one's back, but the right bag portion 21 collapses and air flows into the left bag portion 22 through the communicating portion 23, causing the left side of the upper bag body 2 to become higher than the position of the head P. In this case too, the large buoyancy according to the head difference between the right and left sides can support the head P at a high height.

[0041] Therefore, even when the device is oriented sideways, the effect of the fluid can be effectively obtained.

[0042] In the above embodiment, a central bag portion 24 is provided in the communicating portion 23, but the present invention is not limited to this, and it is not necessary to provide a central bag portion 24 in the communicating portion 23. In short, it is sufficient that the head pressure acting on the head when sleeping on one's side is increased.

[0043] The disclosure regarding the present invention described above can be summarized at least as follows.

[0044] In other words, the fluid pillow of the present invention comprises an upper bag body that encloses a first fluid in a slack state, and a lower bag body that is arranged below the upper bag body and encloses a second fluid different from the first fluid in a slack state, and the lower bag body is characterized in that it has a right bag portion that is arranged on the right side of the upper bag body, a left bag portion that is arranged on the left side of the upper bag body, and a communicating portion that connects the right bag portion and the left bag portion.
