Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a water bed.

[Prior Art] Although water beds are mainly used for medical purposes, they are said to be ideal as ideal bedding due to their functions. In recent years, with the improvement of living environment, they have become widely used in general households and have become smaller and lighter. A variety of water beds are used, from mattress type to large size for two people.

A water bed is a polyvinyl chloride sheet, a watertight flexible sheet material such as rubberized cloth, and a water bag formed in a closed bag shape with a suitable amount of water, a liquid such as a gel, and the like. Although it utilizes a buffering effect, a body pressure uniform dispersion effect, etc., the water bed tends to sink intensively when the load is applied intensively, and it is easy to reach the bottom. A considerable amount of bed thickness is required, and the amount of liquid to be enclosed inevitably increases, making the bed heavier, and special consideration is required not only for the equipment that supports the bed base, etc., but also for the storage location. There is also a drawback that the rocking of the bed due to the movement of the bed increases as the volume of the bed increases.

Therefore, many attempts have been made to solve the problems of weight increase, rocking, bottoming, and the like.

[Problems to be solved by the invention] Among the water beds proposed to solve these problems, a water bed having a plurality of independent water bags (Japanese Utility Model Publication No. 59-5409) is a water bed. Since the bag is small, it disappears in a short time even if it rocks, and because the movement range of water is narrow and small, it is possible to prevent unnatural depression of the body and bottoming out, and the bags can be separated individually. However, because the body pressure is supported by multiple bags, the degree of deformation is different because the body pressure acting on the bags is different. However, the cross section of the bag becomes substantially circular, and the bag moves along with the body movement such as turning over in the bed base, and one bag is placed on the other bag. Problems such as would Tsu occurs, were those bad feeling.

In addition, in a two-person waterbed equipped with two water bags, not only does the adverse effect of wobbling water of one user causing the other user to fall asleep, etc. When the difference in weight is large, a phenomenon in which a bag of a light user gets under the bag of a heavy user is seen, and the problem of water swing caused by the movement of the body and mutual movement of water bags Was more noticeable than a single bed with multiple water bags.

The present invention has been devised in view of these problems, and provides a water bed that prevents movement of the water bag within the bed base during use and provides an ideal sleeping comfort.

[Means for Solving the Problems] That is, according to the present invention, in a water bed in which a plurality of independent water bags are housed and mounted inside a bed base body provided with a frame body at a peripheral portion, adjacent water bags are A water bed in which the contact portion of at least one bag is formed of a watertight flexible sheet material having slip properties.

The bed base of the water bed of the present invention is formed of synthetic resin foam such as polyurethane foam, wood, metal material, synthetic resin material such as FRP, etc., and has an upper opening box shape with a frame body at the peripheral edge. , A conventionally known bed base. A plurality of water bags are arranged in close contact with each other in a space surrounded by the frame of the bed base.

The water bag is formed of a water-tight flexible sheet material such as a polyvinyl chloride sheet in the form of a closed bag having an inlet / outlet port, and water, gel, etc. are enclosed inside the bag.
The plurality of water bags may have different shapes, sizes, or the same shape, but at least have the same thickness. Further, glass fiber, synthetic fiber, synthetic resin foam or the like may be enclosed together with water, and a conventionally known water bag can be used.

In the water bed of the present invention, slipperiness is imparted to the contact portion of the water bag to weaken the frictional force between the water bags so that the movement of one water bag does not reach the other. As a means for this, on the surface of the contact part with the other side of the water bag, silicone type, polyester type
Epoxy-based, polyurethane-based, polyamide-based, fluorine-based synthetic resins, wax, WAX, etc. may be applied, or sheets of these synthetic resins, woven fabrics, non-woven fabrics, and laminates may be laminated. Powders such as silicic acid, silica, starch and calcium carbonate, and granular materials may be applied.

Furthermore, the contact portion of the water bag may be formed of the above-mentioned synthetic resin sheet or laminate, and in the case where the water bag is formed of a synthetic resin sheet such as a polyvinyl chloride sheet, the contact portion The surface may be embossed with satin or silk to reduce the contact friction between the water bags.

[Embodiment] As an embodiment of the present invention, a two-person water bed provided with two water bags will be described as an example.

FIG. 1 is a perspective view showing a waterbed with a bed cover (not shown) removed, and FIG. 2 is a partially cutaway perspective view thereof.

The water bed 1 comprises two water bags 21, 22 in a base 3 of an upper opening box-shaped bed having a frame on the periphery thereof.
Are stored in parallel.

Each of the water bags 21 and 22 is a rectangular parallelepiped closed bag having a suction / drainage port formed of a polyvinyl chloride sheet, and a predetermined amount of water is sealed inside. They are stored and placed in parallel so as to be in close contact with each other so as to support them, and the surface of each contact portion X is coated with silicone resin. By applying the silicone resin, the frictional resistance of the contact portion X is reduced, the movement of the one bag 21 (22) does not move the other bag 22 (21), and the rubbing noise can also be prevented. In addition, since the resin is simply applied, the bed does not feel foreign matter at all, and the application is very easy because it is applied. The silicone resin may be applied to either one of the bags 21 and 22.

The synthetic resin applied to the contact portion X is not limited to silicone resin, but polyester, epoxy, polyurethane, polyamide, fluorine, and other synthetic resins can be used. Not limited to synthetic resin, wax, WAX, oils and fats, etc. can be used. You may apply. These can be appropriately selected depending on the material forming the contact portion X of the bags 21 and 22.

Further, the contact portions X of the bags 21 and 22 are not limited to being coated with a synthetic resin or the like, but powders of talc, silicic acid or the like, or granular materials may be applied, and the synthetic resin sheet, woven fabric, or laminated body may be applied. May be laminated or the contact portion X of the bags 21 and 22 may be formed of these. Further, in the case where the bags 21 and 22 are made of a synthetic resin sheet, the surface of the contact portion X may be embossed with satin or silk to reduce the frictional force.

The present invention is not limited to these examples, and may be a bed provided with a plurality of water bags such as a water bed for one person, and the bag movement preventing material and the slip property are imparted between all bags or on the entire bag surface. Not necessary for. It may be a bag with a lot of movement or only a portion with a lot of movement such as the waist.

[Effect] Since the water bed of the present invention has the contact portion with the other side of the water bag made of the watertight flexible sheet material having slip property, even if the bags contact each other, the contact frictional force is The bag can be weakened to prevent movement of the bag, no scratching noise is generated, and no parts are required, which is convenient for assembly, storage and storage, and does not increase the cost.
