Description

[Detailed description of the invention] (a) Industrial application field The present invention skillfully utilizes the incompressibility of liquid and the compressibility of gas, and can be easily dismantled and relocated to any location. This is about a cushion bed that can be made.

(b) Prior art and its problems A conventionally used cushion bed that utilizes the incompressibility of liquid and the compressibility of gas is disclosed in Japanese Utility Model Application Publication No. 59-70559 as shown in Fig. 4. There is an idea described.

That is, inside a rigid box-shaped frame a, the lower part is filled with a compressible material C in a hermetically sealed manner through an airtight flexible diaphragm, and the upper part is filled with a thin layer of liquid d compared to the compressible material C. By configuring a cushion covering body having a chamber with a vertical axis, the body pressure distribution is dispersed when the patient lies on his/her back, and the shaking that occurs when the patient falls or changes in body position is alleviated.

However, such conventional cushion beds,
Since the compressible material and the liquid, which is an incompressible material, are integrated only through an airtight flexible diaphragm, the compressible material and the liquid, which have different injection volumes, can change their flow states with each other when the patient is supine. This causes distortion in the epidermis of the envelope, and if this distortion occurs on the upper surface of the epidermis, it will make sleeping uncomfortable, and if it occurs at the attachment point between the epidermis and the airtight flexible diaphragm, it will cause water leakage. Not only does this have drawbacks, but the bed itself does not have a structure that allows it to be disassembled and reassembled, so it also has the drawback that it is difficult to relocate the bed when moving or changing rooms.

(c) Problems to be solved by the present invention The problems to be solved by the present invention, that is, the purpose of the present invention is to eliminate the drawbacks of the prior art, and to solve the problem of concentration of body pressure distribution when lying on one's back. Not only can you get a good night's sleep by alleviating the rocking of the bed caused by changes in body position, but there is also no risk of leakage of the encapsulated fluid (it has excellent shape retention and can be used with a small amount of encapsulated fluid). To provide a disassembleable and reassembleable cushion bed which is light in weight and can be disassembled and reassembled to be easily relocated as needed.

(d) Means for solving the problems The present invention has the following structure in order to achieve the object (c). That is, the present invention provides a box-shaped bed base whose four surrounding frames are air bags, an air mat filled with gas stored in the lower part of the box-shaped bed base, and a liquid sealed in the upper part. The water mat is characterized by being integrally covered with a soft, non-stretchable skin having an opening and opening that can be opened and closed.

A water mat is made of a flexible waterproof sheet made of rubberized cloth or vinyl, and has a liquid injection hole on the foot side to seal in liquid such as water. By interposing a liquid filling amount adjusting device in the injection hole, it is possible to arbitrarily select the water mat pressure suitable for the user's physical condition and recovery from fatigue. Furthermore, in order to have a good night's sleep throughout the year, a heating element is built into the bottom of the water mat.
You can also adjust the liquid temperature.

On the other hand, an air mat is also made of a flexible sheet such as rubber-coated cloth or vinyl, and has gas injection holes on the foot side for sealing in gas such as air.

In addition, the width of the water mat and air mat is approximately 80% of the total width of the cushion bed.
It is optimal for the length to be approximately 90% of the total length of the cushion bed in terms of shape retention of the cushion bed. Furthermore,
The amount of water sealed in the water mat and the amount of gas sealed in the air mat are 30% of the total thickness of the bed.
% and 70% is optimal in terms of cushioning properties, shape retention properties, etc.

(e) Effects of the present invention Since the present invention has the above-described configuration, it has the following effects.

a) Since the enclosures of the box-shaped bed base, air mat, and water mat are all fluids, uniform internal pressure can be generated according to Pascal's law. Provides support.

b) Since the air mat is placed under the water mat, even if the bed surface shakes due to turning over, etc., it will be immediately absorbed and attenuated by the cushioning effect caused by the compressibility of the gas sealed in the air mat. Return to calm.

C) By providing the box-shaped Rad base separately from the water mat and air mat, the shape retention of the entire bed is ensured without being restricted by the deformation and rocking of the bed surface that occurs when lying on your back. do.

d) Since the bed is composed of a box-shaped bed base, a water mat, an air mat, and a non-stretchable skin, when relocating the bed, each part can be separated and easily handled by releasing the enclosed fluid. It can be shaped.

(F) Embodiment First, Fig. 1 shows a partially cutaway perspective view of a cushion bed that can be assembled and disassembled according to an embodiment of the present invention, and Fig. 2 is a perspective view taken along line X-X in Fig. 1. The cross-sectional view, FIG. 3, is a cross-sectional view taken along the line XX in FIG. 1.

The cushion bed that can be assembled and dismantled as shown in Figs. 1 to 3 consists of a box-shaped bed base 1 made of a vinyl sheet, an air mat 2, and a thin layer water mat 3 made of rubberized cloth. It is integrally covered with a non-stretchable skin 4.

Here, the box-shaped bed base 1 has a width of 200 to 300 mm in the frame.
It is composed of four surrounding frame parts 1a and a sheet-like bottom part 1b, and when air is sealed in the four surrounding frame parts 1a, the bed width is 950 to 1100 mm and the bed length is 1950 to 210 mm.
0 mm and a bed height of 100 to 3001III11. On the other hand, the air mat 2 has a sheet-like configuration in which five cylindrical air chambers 2a extending in the longitudinal direction of the mat are connected in the width direction of the mat. Further, the non-stretchable skin 4 is provided with a collection port 5 having an opening/closing means consisting of a fastener for storing or taking out the box-shaped bed base 1, air mat 2, and water mat 3.

Further, the box-shaped bed base 1, the air mat 2, and the water mat 3 are provided with an inlet (not shown) for enclosing each fluid.

The thus obtained cushion bed of this embodiment, which can be assembled and dismantled at will, has extremely little concentration of body pressure distribution during sleeping and rocking caused by turning over, and because it can be easily disassembled and assembled, it eliminates the unhygienic conditions that tend to occur on beds that last for a long time. This has the advantage of being able to clean up the sleeping environment, and also allowing the bed to be easily made in any location.

(g) Effects of the present invention Since the present invention has the above-described structure and operation, it produces the following effects.

■ By integrally encasing the box-shaped bed base, air mat, and water mat with a non-stretchable skin, the bed itself can be disassembled and assembled very easily, so when transporting it, the enclosed gas and liquid can be extracted and folded. It has a small external size and can be easily carried, can be easily assembled into a bed at any location, and the bed itself can be relocated very easily.

■ Since the water mat is housed inside the box-shaped bed base, even if water leaks due to damage to the water mat, it will not flow out of the bed.

■ Because the air mat is placed under the water mat, the rocking of the bed caused by changes in body position during sleep is absorbed and attenuated by the cushioning effect of the air mat, returning to a calm state.
Get a good night's sleep.

■ By providing the four surrounding frames on the periphery of the box-shaped bed base independently of the air mattress, the shape of the entire bed can be sufficiently maintained even when the body position changes due to turning over during sleep. You can get a good night's sleep by preventing your skin from falling off.

■ Most of the bed volume is made up of gas and the water mat is a thin layer, which significantly reduces the overall weight of the bed, making it easy to install in any location without reinforcing the floor. can do.
