Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called water bed in which a fluid such as water is hermetically enclosed in a bag-shaped container having a flat rectangular shape, that is, a so-called water bed. The present invention relates to an improvement of a fluid-containing bed in which a degree of flexibility of a predetermined portion with which a human body of a user abuts can be arbitrarily and easily adjusted.

[0002]

2. Description of the Related Art Conventionally, with respect to a fluid-enclosed bed of this type, a fluid such as water is hermetically filled in a bag-shaped container having a flexible and flexible plane rectangular shape. A bed in which the enclosed fluid-filled bag is used as a mat member or a bed member, and the surface portion directly contacted by the human body of the user can be easily fitted in a state following the external form of the human body. Well known as composition.

The degree of softness of the surface of the mat member or the bed member is adjusted mainly by changing the filling amount of the fluid filled in the bag-like container, and by changing the liquid pressure. If the degree of softness of the mat member or the bed member here does not match the user's weight or other conditions, or the preference with individual differences, the original fluid enclosing bed has Comfort is not effectively obtained, and so-called sleeping comfort becomes poor.

[0004]

As described above, in the conventional fluid-enclosed bed, the filling amount of the enclosed fluid is adjusted to change the flexibility of the mat member or the bed member, in other words, The fluid pressure of the enclosed fluid is adjusted by taking the fluid in and out of the mat member or bed member through the liquid injection port. With the adjusting means, not only is it extremely time-consuming to perform the adjusting operation itself, but also the user cannot adjust it while lying on the mat member or bed member, which makes it possible to make fine adjustments according to the user's preference. It has the disadvantage of being difficult.

On the other hand, when adjusting the filling amount of the fluid in the mat member or the bed member, in addition to the mat member or the bed member, the mat member or the liquid injection port of the bed member is piped. Although a fluid storage tank for the fluid to be connected, a liquid feed pump, and other operating mechanisms, control devices, etc. are required independently of each other, a fluid-enclosed bed in which all of these are integrated has been proposed. In many cases, the size and weight of the fluid-encapsulated bed, including its associated equipment, are relatively large, and for example, it was unsuitable for general household use.

The present invention has been made in order to solve the above-mentioned conventional problems, and its purpose is to provide a flexible portion of a predetermined portion with which a human body of a user abuts by a relatively simple mechanical structure. The purpose of the present invention is to provide a fluid-enclosed bed whose degree can be arbitrarily adjusted.

[0007]

In order to achieve the above object, a fluid-enclosed bed according to the present invention comprises a mat member,
Or, in the bed member, after arranging an air chamber of a predetermined volume capable of expanding and contracting in a required corresponding portion, and then filling a required amount of fluid, control into the air chamber here The volume occupancy of the fluid by the specified amount of each of the mat members and the bed member already enclosed in the bed member by supplying the controlled amount of air from the air chamber or exhausting the controlled air amount from the air chamber. The rate, and thus the liquid pressure of the fluid, can be changed.

That is, according to the present invention, a fluid-enclosed bed is used in which a fluid-enclosed bag in which a fluid such as water is sealed and filled in a flexible bag-like container is used as a mat member or a bed member. In the mat member, or a corresponding portion in the bed member, an air chamber having a predetermined volume that can be expanded and contracted is disposed,
A fluid-enclosed bed, characterized in that means for supplying a required amount of air into the air chamber and means for exhausting a required amount of air from the air chamber are provided respectively.

[0009]

Therefore, in the present invention, the air supply means is used for the inflatable and defensible air chamber arranged in the mat member or the bed member filled with the required amount of fluid. By supplying and expanding the required amount of air, it is possible to increase the liquid pressure of the fluid already enclosed in each mat member and bed member to increase the hardness of the surface portion, and conversely By exhausting a required amount of air using an exhaust means to shrink it, the fluid pressure of the already enclosed fluid in each mat member and the bed member can be reduced to lower the hardness of the surface portion. As a result of such a change in the fluid pressure of the fluid, as a result, the hardness of a predetermined portion with which the human body of the user abuts, that is, the degree of flexibility can be arbitrarily adjusted as desired.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a fluid-enclosed bed according to the present invention will be described in detail below with reference to FIG.

FIG. 1 is a cross-sectional explanatory view schematically showing the general construction of a fluid-enclosed bed to which an embodiment of the present invention is applied. In this embodiment, a fluid-enclosed bag is used as a mat member. is there.

In the embodiment shown in FIG. 1, the fluid enclosing bed is set to a required size in the form of a flat rectangular shape, and a concave portion 1 of a predetermined flat rectangular shape is provided on the upper surface side.
2 is recessed, for example, a bed base 11 foamed by using polyurethane foam as a main material, and a suitable plastic sheet or the like to have a required flexibility at least on the surface corresponding portion side, and A mat member 21 by a fluid-filled bag as a bag-like container having a specific volume integrally formed in the portion 12 in a shape that can match as much as possible, and a corresponding portion in the mat member 21, here, as much as possible. An air bag member 31 having an air chamber 32 of a predetermined volume that can be inflated and deflated, which is disposed near the foot side where there is little fear of directly impairing the degree of softness of the surface portion and which is inflatable and defensible. A small pump for air supply that communicates with the air chamber 32 via a check valve 43, for example, in this case, a small pump 42 that can be manually operated while lying down, and a relief valve that directly communicates with the air chamber 32. 4 is constituted by a flexibility adjustment device 41 comprising taken out, respectively.

Further, the mat member 21 is provided with a liquid supply valve 22 and a liquid discharge valve 23 also serving as exhaust gas, and by utilizing these valves 22 and 23, the mat member 21 can be used. For inside, a predetermined amount,
Here, the surface portion having a required flexibility is filled and sealed with a fluid 24 such as water in a predetermined amount so as to give an average degree of flexibility in a sealed state, and the air chamber of the air bag member 31. Even within 32,
A preload is provided by filling an appropriate amount of air.

In the drawing, reference numeral 51 indicates the mat member 2
1 is a cloth cover that covers the entire body, and 52 is a bed cover that covers the entire fluid-enclosed bed.

However, in the case of the fluid-filled bed of the embodiment having the above-mentioned structure, the small pump 42 of the flexibility adjusting device 41 or the relief valve 44 is operated, so that the former small pump 42 is non-returned. Air chamber 3 via valve 43
A desired amount of air is supplied to the inside of the air bag 2, and the air bag member 31 is inflated corresponding to the supplied amount of air, whereby a specified amount of the enclosed fluid 24 in the mat member 21 having a specified volume is provided. The volume occupancy rate of the fluid, and hence the fluid pressure, can be increased to set the flexibility of the surface portion to a relatively high level. On the other hand, in the latter relief valve 44, conversely, the fluid provided to the fluid 24 is Due to the pressure, the required amount of air filled in the air chamber 32 is automatically evacuated, causing the air bag member 31 to contract in response to the amount of air evacuated, thereby causing a mat of a specific volume to be generated. The volume occupancy rate of the specific amount of the enclosed fluid 24 in the member 21, and consequently the fluid pressure can be reduced to set the flexibility of the surface portion to a lower level, and with such a fluid pressure change in the fluid 24, As a result, contact with the human body of the user A flexible degree of a predetermined portion comprised of as it can be arbitrarily adjusted as desired.

Since each of the above operations can be performed while the user is lying on the mat member 21, the degree of flexibility can be finely adjusted according to the taste of the user, and for example, from the bed. There is an advantage that it can be used for a sick person when he cannot get up or for an elderly person. In addition, when the air bag member 31 is arranged at the bottom of the mat member 21 near the foot side, the air chamber 32 is There is no fear of causing discomfort due to expansion and contraction, and structurally, the check valve as the arrangement of the air bag member 31 in the mat member 21 and the flexibility adjusting device 41 in comparison with the conventional one. Small pump 42 with 43 and relief valve 4
Since only the number 4 is added, the size and weight increase of the entire bed structure can be neglected, and it can be sufficiently applied to general household use.

Further, in the above embodiment, the case where the fluid-filled bag is used as the mat member has been described, but it is needless to say that the same can be applied to the case where the fluid-filled bag is used as the bed member.
