Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a waterbed.

[0002]

[Prior Art]

 A conventional water bed consists of a water-filled mattress, a liner that holds the mattress in place, a cover that covers both mattresses, and a frame that holds the entire cushion. This liner consists of a hard polyurethane core wrapped in a vinyl bag-like sheet. And since this cover covers both the water-filled mattress and the liner as a whole, fasteners can be attached to three or four sides of the upper surface, and only one part can be opened and closed to put the water-filled mattress in and out. It was made possible.

[0003]

[Problems to be solved by the device]

 However, the above water bed has the following difficulties. That is, since the liner is formed by processing hard polyurethane from the beginning to fix the mattress, the liner becomes very large in volume and is uneconomical during transportation and storage. Moreover, since the material of the sheet that wraps the liner is vinyl, the material easily expands and contracts and loses its shape.

Further, since the above-mentioned cover covers the entire surface of the mattress and the liner containing water, the air permeability is deteriorated, and the mattress and the liner are easily moistened and insects are liable to be spread. Also, the mattress and liner must be lifted when replacing the cover, which is very laborious.

[0005]

[Means for Solving the Problems] In order to solve the above problems, the inventor has made a liner composed of a mattress for containing water, a liner for supporting and stabilizing the mattress, and a cover for covering both of them. The inner filling member is made of a material that contracts when deflated and can be restored at atmospheric pressure, and the sheet that wraps the surface of the liner has air holes that allow deflation. I devised a water bed that The water bed liner is preferably made of a material that contracts in the deflated state and expands when the air enters.

The inventor has also devised a water bed in which a sheet that encloses the liner is formed with a hole through which air enters and a plug that closes the hole. Furthermore, the inventor has devised the water bed according to claim 1, wherein the sheet enclosing the liner is made of a material that does not expand and contract. The inventor has also devised a waterbed that does not cover the center of the bottom surface of the liner, but has a cover that covers only the top surface of the mattress and liner, the side surface of the liner, and the peripheral area of the bottom surface.

[0007]

[Action]

 According to the above water bed, during transportation and storage, air can not be put into the sheet and the volume can be reduced by making the liner a vacuum state, and at the time of installation, it can be easily opened by opening the air hole plug. The liner can be inflated.

Further, according to the above water bed, since the sheet that wraps the liner is made of a material that does not expand and contract, it does not easily lose its shape. Further, according to the above water bed, since the cover does not cover the central portion of the bottom surface of the liner, it is possible to prevent the mattress and the liner from getting wet easily, and it is possible to easily replace the cover.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing the structure of a water bed of the embodiment, and FIG. 1 is a perspective view showing a state in which the water bed of the embodiment is disassembled. The mattress 1 is made of a bag-shaped vinyl material having a water inlet 6. The liner 2 is a sheet made of a soft, open-cell, high-density foam material, such as polyurethane, with a recess formed on the top surface for installing the mattress 1, and made of a vinyl material containing non-stretchable fibers. I'm out.

The volume of the high-density foamed material when wrapped in a sheet is 95% or less, preferably 80 to 90%, when not wrapped in a sheet. A large number of air holes 7 are formed in the sheet. Further, a surface fastener 8 is attached to the lower surface in a shape corresponding to the surface fastener 8 of the cover 3 described later in order to fix the cover 3.

The cover 3 covers the entire upper surface of the water-filled mattress side, almost the entire lower surface is opened, and only a “margin” is left on the lower surface of the liner 2 for stopping the cover, and the hook-and-loop fastener 8 is a “margin” part. It is attached to the entire surface. However, since the hook-and-loop fastener 8 is attached to fix the cover 3, it may be partially attached to the cover 3 instead of continuously within a range necessary for that purpose.

The floor panel 4 includes a temperature sensor 9, a temperature controller 10, and a heater 11 for adjusting the temperature of the cushion portion, particularly the mattress. Further, the floor panel 4 is for adjusting the temperature of the cushion portion to make the sleep comfortable, so it can be omitted.

Next, a procedure for assembling the water bed of the present invention will be described. The floor panel 4 is installed on the frame 5, and the liner 2 is placed on it. At this time, since the liner 2 is compressed in a vacuum state, the stopper of the air hole 7 is loosened to allow air to enter, and the liner 2 is returned to its original shape. At this time, since the air pressure inside the compressed sheet of the liner 2 is low, the air naturally enters the liner 2 only by loosening the plug of the air hole 7, so that no special means is required.

When the liner 2 has spread sufficiently, the mattress 1 is laid in the depression on the upper surface of the liner 2 and water is poured from the water injection port 6. At this time, water must be adjusted and adjusted so that the mattress is not biased or twisted. When the water injection is completed, the liner 2 containing the mattress 1 is covered with the cover 3. Gradually cover the lower open surface of the cover 3, and fold the lower "margin" under the liner 2. Then, the surface fastener 8 attached to the folded portion is adhered to the surface fastener attached below the liner 2.

Thus, the mattress 1 filled with water is installed in the liner 2 that supports and stabilizes it, and the mattress 1 and the liner 2 are covered by the cover 3, and these cushion portions cover the floor panel 4. It is laid and installed on the frame 5, and the assembly procedure is completed.

[0016]

[Effect of the device]

 According to this invention, the volume of the liner can be reduced, and it can be transported and stored very easily and economically. Further, according to this invention, since the sheet that wraps the liner is made of a material that does not expand and contract, it is possible to prevent the deformation of the sheet. Further, according to the present invention, the cover does not cover the central portion of the bottom surface of the liner, so that the mattress and the liner are prevented from getting wet easily and the cover can be easily replaced.
