Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in mattresses for waterbeds.

Conventionally, this type of mattress has been constructed by placing a water bag filled with water inside a box-shaped flat frame called a shell member, and covering the edges of the water bag and the shell member with a thin cloth. Compared to mattresses using elastic materials such as coil springs or foamed urethane resin, the structure described above not only lacks aesthetic structure such as poor appearance due to the above-mentioned structure and poor usability at corners, but also causes water bags. In order for the bottom plate of the shell member to support the heavy weight of the filled water, the foamed urethane resin that covers the bottom plate must be made sufficiently thick.

In view of the above-mentioned drawbacks, the present invention was devised for the purpose of providing a mattress exhibiting an aesthetic form. It is an object of the present invention to provide a mattress having a luxurious feel, which is provided with an exterior member and is configured such that an exterior covering material such as a quilted sheet surrounding the mattress can be removed from the outside of the exterior member. A reinforcing plate made of plywood, which corresponds to the planar shape of the water bag, is interposed between the bottom plates of the shell member to equalize the surface pressure applied to the bottom surface and stabilize the surface shape.

Next, an embodiment of the present invention will be described with reference to the drawings. A shell member 1 made of a foamed resin heat-retaining elastic member such as a slightly hard urethane foam has a rectangular frame 1a with a substantially trapezoidal cross section and a bottom plate 1b. It is structured as an open flat box, and a flat heat generating plate 2 which generates heat by electricity is placed on the upper surface of the bottom plate 1b.

Further, an exterior member 3 made of the same material as the shell member 1 or a soft foamed resin is provided on the peripheral side and bottom outer periphery of the shell member 1, and the exterior peripheral member 3a having a U-shaped cross section has both ends 3a'. , 3a' are fitted to the upper and lower ends of the frame 1a, and reinforcements made of veneer plywood or the like are provided on the lower surface of the bottom plate 1b and have an appropriate thickness and have a substantially planar shape for the water bag 5 described later. An exterior bottom member 3b that is continuous with the end portion 3a' of the exterior circumferential member 3a via the plate 4 is fixedly screwed.

On the upper surface of the heat generating plate 2, the upper surface of the bottom plate 1b, the inner wall of the frame 1a, and the inner surface and upper surface of the end 3a' of the outer circumferential member 3a, liners 6 are made of a waterproof sheet member with each surface continuously watertight.
is laid, and the water bag 5 is placed inside the shell member 1 via the liner 6.

Water a is injected into the water bag 5 from a stopperable water supply/drain port 8 provided at one end of the upper sheet 5a, and when the water a is filled, the center of the upper sheet 5a is slightly It bulges to a higher position and has an upper surface that is continuous with the upper surface of the end portion 3a' of the exterior member 3a.

The outer cover member 9 surrounding the upper surface of the water bag 5 and the outer periphery of the outer cover member 3 is provided with a zipper 10 that extends approximately all the way around the circumference and is made of quilted woven fabric or the like.
A and the lower cloth 9b can be opened and closed, and can be removed from the above-mentioned members to be installed inside. Decorative tape 11 is sewn around the corners and around the edges where the fastener 10 is attached.

In the figure, 7 is a flexible moisture-absorbing mat made of a sponge sheet, cotton, mat, etc., provided as necessary.
It is inserted into and removed from a pocket 12 provided on the inner surface of the upper cloth 9a.

Therefore, it is highly hygroscopic, and at the same time, the moisture-absorbing mat 7 is removable so that it can be washed, and the water bag 5 absorbs the wave-like vibrations on the upper sheet surface, so that a comfortable sleep can be obtained. .

The water bed mattress having the above structure is used by filling water bag 5 with water a from water supply/drainage port 8, and energizing heating plate 2 to maintain water a at an appropriate temperature. If this is more preferable, a heat absorbing plate using semiconductor elements or the like may be installed.

As explained above, the structure of the mattress of the present invention is that the exterior member 3 for shaping the outer shape is provided on the outer periphery of the shell member 1, and the exterior member 9 that surrounds the entire periphery is made of a quilted woven fabric that has a heavy feel. Therefore, it can provide a high-class feel, and since the outer covering member 9 can be freely removed by the fastener 10, cleaning etc. are easy.

Furthermore, a reinforcing plate 4 is provided on the lower surface of the shell member 1 to evenly receive the load of the water a filled in the water bag 5, which makes it possible to equalize the surface pressure applied to the base plate of the bed. A liner 6 is laid around the bottom of the water bag 5, so that even if the temporary water bag 5 is damaged and water leaks, not only the heat generating plate 2 but also the shell member 1 will not be wetted and damaged, and dew drops that occur during cooling are also isolated. It has extremely high practical effects.
