Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of 4J4J:] This invention relates to a water bed in which water is poured into the inside of a bag-like member so that the part that comes into contact with the body is adapted to the water bed.

[Prior Art 1 Waterbeds with various structures in which water is poured inside have been known. All of these waterbed structures are simply filled with water in a closed container with a rectangular planar shape.

For this reason, with conventional waterbeds, for example, when a user gets on and off the waterbed or turns over, the water inside flows and the bed sways, making the bed unstable. It can make people feel anxious and prevent them from getting a good night's sleep.

Furthermore, in the above-mentioned conventional waterbed, when the body weight is applied to the central part during use, the water concentrates on the periphery, causing the body to sink deeper into the bed. In order to prevent this, various countermeasures have been taken. For example, inside a closed container configured in the shape of a rectangular bag, measures such as connecting multiple locations on the top and bottom surfaces with strips or strings have been taken, but the flow of water due to the body weight is rapid and large. , the strip or string-like piece will be pulled suddenly, and a very large force will be applied to the connection between the table piece and the inside of the sealed container.
Failure to provide sufficient strength to these parts will result in damage.

Furthermore, with conventional waterbeds, regardless of the natural shape of the body, the body's weight is concentrated in the center and the body sinks, disrupting the natural state of the body and making it uncomfortable to sleep.

[Problem that the invention seeks to solve]

This invention solves the problem of damage to the bed due to the rapid flow of water and instability when getting on and off the bed in the conventional waterbed described above, as well as the problem of the body's natural posture due to the concentrated sinking of the body. This is an attempt to solve the problem of not being able to maintain the

[Means for solving problems]

As a specific means for solving the above-mentioned problems, the present invention provides a sealed container made of a watertight flexible sheet having a rectangular bag portion, and a container made of a spongy member or an open foam material. The present invention provides a water bed characterized by being filled with a mat-like member and water, in which rapid flow of water is suppressed by the mat-like member, and
Intensive subduction is also suppressed.

〔Example〕

The present invention will now be described with reference to several illustrated embodiments.

First, in the first embodiment shown in FIGS. 1 and 2, reference numeral 1 does not indicate a water bed, and the water bed is an airtight container formed into a mat or bag shape using a flexible sheet made of synthetic resin. 2, and a synthetic resin open foam or spongy mat-like member 3 housed therein. The flexible sheet is made of, for example, a rubber or soft synthetic resin sheet, or a composite material of these materials and cloth, and the mat-like member is made of, for example, polyurethane,
A synthetic resin such as vinyl chloride or polyethylene is foamed to have open, spongy cells, which are then formed into a mat to form an open foam. The closed container 2 is provided with a plurality of valves 5 for injecting or discharging water 4. The water bed 1 configured in this manner is used, for example, by being placed on a bed base 6 whose four peripheries are constituted by side plates, and by holding the circumferential side surfaces by the side plates.

3 and 4 show a second embodiment. In the first embodiment, the mat member 3 is used uniformly over the entire surface, but in this second embodiment, The density of the open foam was changed depending on the weight applied. In other words, since it is used as a bed,
The head and legs of the human body have few ridges on which the weight is applied, so a coarse and dense mat-like member 3a made of open foam is used so that the weight can be applied to the ridges. A high-density mat-like member 3b made of IFA foam is used so that the abutting part does not sink too much since a large amount of weight is applied. Then, it is stored in a sealed container 2 and used in the same manner as in the previous embodiment.

In the third embodiment shown in FIGS. 5 and 6, even when mat-like members with the same foam density are used, it can be accommodated depending on the position where the weight is applied. A plurality of holes 7 are bored at appropriate locations. By removing these holes, it becomes easier to sink than other parts. In this case as well, the mat-like member is housed in the closed container 2 and used in the same manner as in the previous embodiment.

[Function] In the water bed of the present invention having the above-described configuration, after the airtight container 2 is set in a predetermined position, a predetermined amount of water is injected into the interior via the valve 5 to form a bed, and the user can Even if you step on it or turn over on it, the open foam mat member 3 stored inside will act as a resistance to the flow of water, so the water will not flow! Because of this, the sealed container 2 does not deform immediately or the water inside remains in a state of agitation, unlike when it is simply filled with water, and deforms slowly. Therefore, you will not become unstable when you try to get on or off the bed, and even if you move your body while lying on the bed, there will be no 81 movements, so you will not have to worry about things that will disturb your sleep. Never. Furthermore, since the flow of the water 4 is slow, there is no possibility that a large force will be applied to a part of the Tlff device 2 due to a sudden flow of water, causing damage, and the strength will be sufficiently reinforced. additional consideration is no longer necessary.

Furthermore, the open foam mat member 3 inside the airtight container 2 retains water to prevent water from moving excessively to the periphery, and the mat member 3 supports the body from sinking, so the overall It can reduce sinking. Roughly speaking, differences in the contact pressure of various parts of the body against the bed cause differences in sinking, which reduces the possibility that the natural state of the body's posture is disrupted.

Moreover, as shown in FIGS. 3 and 4, the mat-like member 3
By combining foams with different densities that make up the body, the elasticity of each part can be changed.For example, the part where the m part of the body is located is made of a high density foam, and the degree of sinking is adjusted. The natural state of the body posture is maintained. Furthermore, the above-mentioned adjustment of the degree of depression is also possible in other embodiments shown in FIGS. 5 and 6. This is done by creating holes in the upper and lower surfaces of the foam at appropriate locations to adjust the apparent elasticity. In other words, the apparent elasticity is reduced in areas where no load m is applied, and the apparent elasticity is increased in areas where a lot of fine hair is applied, thereby adjusting the degree of sinking of the body and maintaining a natural body posture. This allows the bed to remain in a comfortable state, so the comfort of sleeping will not be compromised.

〔Effect of the invention〕

As explained above, the waterbed according to the present invention has a mat-like material made of a spongy material or an open-cell foam placed inside a sealed container made of a water-tight pliable sheet and formed into a rectangular bag portion. Since the structure is filled with a member and water, the fluidity of the water filled inside is slowed down by the mat-like member, which increases the sense of stability when getting on and off the bed, and eliminates overall shaking. As a result, it has excellent effects when it no longer interferes with sleep.

In addition, since the mat-like member supports the load applied to the bed and reduces the overall sinking of the bed, concentrated sinking is eliminated, which also has the excellent effect of improving sleeping comfort.

Furthermore, the degree of sinking of each part can be reduced by using foam with different densities in some parts of the mat-like member, or by having holes cut out in some parts of the foam. Since it can be adjusted appropriately, the natural state of the body is maintained, which also has the effect of making sleeping more comfortable.

Furthermore, since the mat-like member can suppress the sudden flow of water, it also has the excellent effect of preventing damage to the sealed container.
