Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a water bed in which the thickness (height) of the water bag is reduced and the weight is reduced.

[0002]

[Prior art]

 In recent years, water beds with excellent cushioning properties have been attracting attention as bedding due to the improvement of living environment.However, since water beds are filled with a large amount of liquid such as water in water bags. However, the bed itself was very heavy and could not be moved easily.

[0003]

[Problems to be solved by the device]

 Therefore, in order to reduce the weight of the water bed, if the thickness (height) of the water bag is reduced, the cushioning material and the like built into the water bag will be reduced by the weight of the person when lying on the water bed. It may stick to the bottom surface, which may cause a so-called bottoming phenomenon. When such a bottoming phenomenon occurs, the convection of the liquid enclosed in the water bag deteriorates, the liquid temperature in the water bag becomes uneven, and the cushioning property of the water bag deteriorates. There was a drawback that the feeling was significantly impaired. In addition, the heater for heating the liquid enclosed in the water bed may be overheated.

The present invention has been made in order to overcome such a conventional problem, and an object thereof is not to impair the original function of a water bed even if the thickness (height) of the water bag is reduced. To provide a waterbed.

[0005]

[Means for Solving the Problems]

 The present invention comprises a flat bag-shaped water bag, a buoyant cushioning material contained in the water bag, and a liquid sealed in the water bag, and is adjacent to the water bag. In a water bed equipped with a heater for heating the liquid in the water bag, a cushioning material having water permeability in the water bag, at least facing the heater, and having an appropriate waist strength. The present invention provides a water bed characterized in that

[0006]

[Action]

 In this way, by arranging a cushioning material that has water permeability at least facing the heater and has appropriate waist strength in the water bag, the thickness (height) of the water bag can be reduced. Even if it is thin, it does not impair the original function of the waterbed.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In addition, in this embodiment, a water bed in which a cushioning material having water permeability and an appropriate stiffness is arranged in the water bag so as to face the heater is taken as an example.

In FIG. 1, reference numeral 10 denotes a water bed, and the water bed 10 has a water bag 20 and a wooden frame (not shown) for accommodating the water bag 20, and an interposing therebetween. It is composed of a safety liner 30.

The water bag 20 is a flat rectangular parallelepiped bag having a predetermined width, length and thickness (height), and is formed by, for example, high-frequency welding a sheet made of a synthetic resin such as vinyl chloride resin. Has been done. Further, the water bag 20 is provided with a spigot (not shown).

On the other hand, the safety liner 30 is provided so that the liquid does not flow out into the bedroom even when the liquid leaks from the water bag 20, and has a bottomed container shape with only the upper surface opened. ing. Like the water bag 20, it is formed by high-frequency welding a synthetic resin sheet such as vinyl chloride resin.

In the water bag 20, a liquid 21 such as water and a cushioning material 22 having buoyancy are built. The cushioning material 22 is formed by intertwining synthetic fibers such as polyester fibers and nylon fibers, and has a sheet-like non-woven fabric 221 having a high porosity of 80% or more and high water permeability and air permeability, a foamed polyethylene sheet, and a foamed sheet. A sheet-like floating body 222 having closed cells such as a polypropylene sheet and a foamed styrene sheet is laminated in layers. It is preferable that the size of the cushioning material 22 is equal to or slightly smaller than the area of the upper surface 20b of the water bag 20.

On the other hand, on the bottom surface 30a of the safety liner 30, a fixed bag 31 for housing a heater is provided, in which a heater 32 composed of a planar heating element is housed, and for housing a control device such as a controller or thermistor. A fixed bag 33 is provided, and a control device 34 such as a controller or thermistor is stored in the fixed bag 33.

Further, in the present invention, in order to prevent the bottoming phenomenon, a cushion material 23 having water permeability and an appropriate waist strength is provided at a position facing the lower surface of the cushioning material 22 facing the heater 32. It is wrapped in 24 and attached.

The cushion material 23 is, for example, a type of filter material in which bulky denier short polyvinylidene chloride short fibers (bristle yarns) are three-dimensionally arranged and then point-bonded with polyvinylidene chloride resin latex (adhesive). [Kureharon Lock (trade name)] is cut into a predetermined size and used, and the size is equal to or slightly larger than the area of the heater 32. Even if the cushioning material 22 slightly shifts sideways during use, the heater It does not come off from the 32 position. The net 24 is made of a double structure knitted fabric in which synthetic fibers such as polyester and nylon are knitted by a double Russell warp knitting machine.

The cushioning material 23 wrapped with the cushioning material 22 and the net 24 is integrally connected by a fastener 25 such as a binding string, and the water bag 20 is secured by a belt 26 so as not to move laterally. Is connected to the bottom surface 20a.

Due to the above-mentioned structure, when the person lays on the water bed 10, even if the upper surface 20b of the water bag 20 or the cushioning material 22 sinks due to the weight of the person, the weight of the person lying on the bed can be appropriately adjusted. Since it is supported by the cushion material 23 having a high waist strength, the so-called bottoming phenomenon in which the cushioning material 22 directly contacts the bottom surface 20a of the water bag 20 can be avoided. Furthermore, since the cushion material 23 has water permeability, the liquid 21 in the water bag 20 is uniformly heated, and the usability is not impaired. Also, overheating of the heater 32 itself can be prevented.

Although the embodiment of the present invention has been described above, the present invention is not limited to this embodiment and may be included in the present invention even if there are modifications without departing from the scope of the invention. Of.

That is, in the above description, the case where one cushion member 23 is arranged at a position facing the heater 32 has been described. However, as shown in FIG. 2, the cushion member 23 cut into a column shape is used. A large number may be arranged below the cushioning material 22 while maintaining a predetermined interval.

Further, the cushion material 23 is not limited to the above-mentioned material, but may be any other material as long as it has compression elasticity and can hold space.

Further, the net is not limited to the above-mentioned material, and any other material may be used as long as it prevents contact between the cushion material 23 and the water bag 20 and has water permeability. Further, the net 24 is not necessary for use unless the cushion member 23 may damage the water bag 20.

[0020]

[Effect of device]

 As described above, according to the present invention, since the cushioning material which has water permeability and at least has an appropriate stiffness against the heater is disposed in the water bag, the thickness of the water bag (high Even if the thickness is reduced, the so-called bottoming phenomenon in which the cushioning material contained in the water bag adheres to the bottom surface of the water bag does not occur. As a result, the convection of the liquid enclosed in the water bag is deteriorated, the liquid temperature in the water bag becomes uneven, and the cushioning property is not deteriorated.
