[Industrial applications]

 The present invention relates to a water bed capable of cooling and warming the body by forming water into the bed.

[0002]

[Prior art]

 Various types of water beds have been proposed, but generally, a water bag that stores water is stored in a box-shaped bag storage base. The base body for bag accommodation is made of a hard synthetic resin material so that the water bag is fixed and has an opening at the top. In addition, this water bed is provided with an openable / closable outer bag body that covers the entire body in a state where the water bag is accommodated in the bag accommodating base.

However, when using this water bed, if the body is placed on the water bag, the body can be kept in a state of being floated on the water due to the buoyancy of the water in the water bag, so that the user can rest comfortably. be able to. In addition, when this water bed is used in the summer, the body can be cooled with cold water, while the water can be warmed with hot water by heating the water bag with a panel heater or the like.

[0004]

[Problems to be solved by the device]

 By the way, when the above-mentioned conventional water bed is formed as a double bed type and is used by two people, since there is no partition along the length direction, hot water heated by the heat of the person next to There was a drawback that the bed side next to the bed was heated by the reflux and the body of the person sleeping on this bed was warmed.

Further, when the water bag is heated by using a panel heater or the like, the entire double bed is heated, so that there remains a problem that the water bag cannot be used at a temperature of its own preference. In addition, when two people sleep in a double bed and one of them moves over by rolling over, the water bag sways and is transmitted to the person next to the person. The present invention aims to solve the above problems.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the water bed of the present invention comprises two mattresses each having a space for containing water therein, and at least one of the mattresses has an independent narrow separation chamber along the contact side. Two mattresses that are provided along the entire length in the longitudinal direction and are filled with a filling material that has thermal insulation and contractibility and that is located in the center of the space. Is characterized by.

[0007]

[Action]

 Since the water bed of the present invention is provided with an independent narrow separation room along the adjacent side of at least one mattress, the empty space of the mattress is divided into the left and right centering on this separation room. By increasing the size of the mattress, a water bed for two people can be constructed. The water-bed separation room is filled with a heat-insulating and shrinkable filler, so if you fold the mattress without water in the left and right cavities during transportation and storage, the filler will be filled. The shrinkage reduces the overall volume.

On the other hand, when the mattress is expanded to put water in the left and right cavities at the time of use to form a water bed for two people, the water vapor separating chamber has a heat insulating property. When the left and right sides are used, even if the stored water is warmed by heat radiation from each person's body, the separation of the hot water is regulated by the isolation chamber, and the heat transfer is suppressed by the heat insulating filler. Also, when two people sleep on this water bed, even if one person moves by rolling over, etc. and the mattress shakes, it is prevented from being transmitted to the adjacent mattress because it is partitioned by the isolation room.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 is a perspective view of the water bed, FIG. 2 is a cross-sectional view of the water bed, and FIG. 3 is an exploded perspective view of the water bed 1. The water bed 1 is a double bed type and is configured by including left and right mattresses 2, 3, a liner 5, a cover 6, panel heaters 7, 8 and the like, and is provided with a bag body for venting air.

The left and right mattresses 2 and 3 have a substantially rectangular shape and are formed in a wide bag shape using a vinyl material. The mattresses 2 and 3 have cavities 2a and 3a for containing water, and water injection ports 2c and 3c are provided on the upper surfaces 2b and 3b, respectively. The mattress 3 is provided with a separation chamber 4. The separation chamber 4 is formed to have a narrow width by integrally providing a partition wall 4a along the adjacent side 3d of the right mattress 3 and has a heat insulating and compressive filling material 4b in the hollow portion. Is filled. It should be noted that although not shown in the drawing, an air hole for venting air with a plug is provided on one side of the separation chamber 4.

The liner 5 is formed into a concave shape as a whole, and the mattresses 2 and 3 are installed in the concave portion 5a. The liner 5 is formed by wrapping a high-density foam material 5c in a sheet 5b. This sheet 5b is made of a non-stretchable fiber-containing vinyl material, and is covered with a high-density foam material 5c made of a soft, open-cell material such as polyurethane. A large number of air holes 5d provided with plugs are provided on the outer surface of the sheet 5b.

The volume of the high-density foamed material 5c when wrapped with the sheet 5b is 95% or less, preferably 80 to 90% of that when not wrapped with the sheet 5b. Then, in order to fix a cover 6 described later, a surface fastener (not shown) is attached to the outer peripheral portion of the lower surface of the sheet 5b corresponding to the surface fastener 6b of the cover 6.

The cover 6 has a shape that can cover the entire upper surfaces 2b and 3b of the water-filled mattresses 2 and 3 and open almost the entire lower surface of the liner 5, and is made of a quilted material. Has been formed. A surface fastener 6b is attached to the entire edge 6a of the cover 6 leaving a "margin". When the surface fastener 6b is fixed to the surface fastener of the liner 5, the mattresses 2 and 3 and the liner 5 can be covered. Since the surface fastener 6b is attached to fix the cover 6, it may be partially attached rather than continuous within the range necessary for that purpose.

The panel heaters 7 and 8 are respectively placed on the upper surface 11b of the bed 11 having the six leg portions 11a corresponding to the left and right mattresses 2 and 3, respectively. Then, each of the panel heaters 7 and 8 is connected to a temperature controller 10 having a temperature sensor 9. As a result, when the temperature controller 10 is set to a temperature according to the user's preference during use, the stored water temperatures in the left and right empty portions 2a and 3a, which are cushion portions, are individually adjusted based on the set temperature. It is what is done.

Next, the assembling work of the water bed will be described. First, the panel heaters 7 and 8 are arranged on the bed 11, and the liner 5 is placed thereon. At this time, since the liner 5 is compressed in a vacuum state, the stopper of the air hole 5d is loosened and air is introduced to restore the liner 5 to its original shape. At this time, since the air pressure inside the sheet 5b of the liner 5 in the compressed state is low, the air naturally enters the inside by simply loosening the plug of the air hole 5d, so that no special means is required.

Next, when the liner 5 is sufficiently expanded, the mattresses 2 and 3 are laid in the recess 5a, and water is introduced from the respective water injection ports 2c and 3c. At this time, it is necessary to adjust the water injection so that the bag-shaped mattresses 2 and 3 are not biased or twisted. Then, when this water injection is completed, the liner 5 containing the mattresses 2 and 3 is covered with the cover 6. In this case, the cover 6 is gradually covered from the lower open surface, and the lower "margin" is folded under the liner 5. Then, the surface fastener 6b attached to the folded portion is adhered to the surface fastener attached below the liner 5.

As a result, the mattresses 2 and 3 filled with water are installed in the liner 5 that supports and stabilizes the mattresses 2 and 3, and the cover 6 covers the mattresses 2 and 3 and the liner 5. Then, these cushion parts are installed on the bed 11 via the panel heaters 7 and 8, and the assembling work is completed.

This water bed 1 is a double bed type that is divided into right and left by a separation chamber 4 provided in the center along the adjacent side 3 d of the mattress 3, so that it can be used for one person or two people. . At this time, by heating the panel heaters 7 and 8 or not heating them, the left mattress 2 or the right mattress 3 can be individually heated, and can be used at a temperature according to their own preference. In addition, since the isolation chamber 4 has a heat insulating property, heat transfer between the left and right mattresses 2 and 3 is significantly suppressed during use, and the body of an adjacent person is warmed, which causes discomfort. To be prevented.

Further, since it is partitioned by the isolated room 4, even if one mattress sways when one person moves by rolling over, etc., the sway is prevented from being transmitted to the adjacent mattress. The problem of being unable to solve is solved. In addition, when water is drained from the left and right empty portions 2a and 3a of the mattresses 2 and 3 and folded, the filling material 4b of the separation chamber 4 contracts, so that the entire volume can be reduced, and transportation and storage are easy. Becomes

[0020]

As described above, according to the present invention, at least one of the side-by-side mattresses is formed with an independent narrow separation chamber over the entire length in the longitudinal direction, so that the heat transfer between the left and right mattresses is significantly increased. It is suppressed, and the problem that the heat of the person next to you warms the body of another person and makes you feel uncomfortable is prevented.

Further, when each mattress is heated by a panel heater or the like, there is an effect that each of the left and right can be adjusted to a desired temperature before use. In addition, since the separation room is divided into partitions, the problem that both mattresses sway and are transmitted to the next person when one person moves by turning over when sleeping, etc., has the advantage that each person can sleep well.
