Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bed posture changing device.

[0002]

2. Description of the Related Art As a method for a person lying on the floor to change the posture of the body, for example, by changing the angle of the upper body, an air bag is placed directly below the mat or the futon and air is supplied to the air bag. The position of the mat or the futon is changed by transmitting the expansion / contraction caused by the discharge to the mat or the futon.

[0003]

However, the method of directly transmitting the expansion / contraction of the air bladder to the mat or the futon is unstable due to the eccentric load of the user's weight, and the bed is unstable. Or, the accuracy of the changing position of the futon is lacking, which is unsatisfactory for the user.

An object of the present invention is to provide a bedding posture changing apparatus capable of stable and highly accurate posture change.

[0005]

According to the present invention, a bottom plate, an upper plate rotatably attached to the bottom plate, and an inflatable / contractible air bag arranged between the bottom plate and the upper plate,
There is provided a bedding posture changing device comprising: an air supply / exhaust means for supplying / exhausting air to / from the air bag.

Preferably, the air bag has a deformable extension piece, and the extension piece is fixed to a rotation fulcrum portion of the bottom plate and the upper plate. Further, it is preferable that a plurality of the air bags be provided and that the air bags communicate with each other.

Further, according to the present invention, a bottom plate, an upper plate rotatably attached to the bottom plate, a first blind plate rotatably attached to the bottom plate, the first blind plate and the A second blind plate rotatably attached to the upper plate, an air bag arranged between the bottom plate and the upper plate, and means for supplying and exhausting air to the air bag. A posture changing apparatus for a bedding is provided.

Further, according to the present invention, the upper plate, the bottom plate and the two blind plates are arranged on the flexible sheet so as to be separated from each other and the two blind plates are located between the upper plate and the bottom plate.
Further, a soft sheet is arranged on the upper plate, the bottom plate and the two blind plates, and the two soft sheets are welded along the outer peripheries of the upper plate, the bottom plate and the two blind plates and have an extension piece. An air bag is placed on the front soft sheet, the soft sheet is folded so that the air bag is located between the top plate and the bottom plate, and the extended side of the air bag and both ends of the soft sheet are welded and fixed. There is provided a method of manufacturing a posture changing device for bedding.

[0009]

When the air is supplied to the air bag, it expands while pressing the two hard top and bottom plates. Therefore, the force from the bladder is not transmitted directly to the bed or futon, but through the rigid top plate. Therefore, the force transmitted to the bed or the futon becomes substantially uniform over the entire surface of the upper plate, and becomes stable.

When the extension piece of the air bag is fixed to the rotation fulcrum of the bottom plate and the upper plate, the movement of the air bag due to the force exerted on the air bag from the upper plate is prevented. If a plurality of air bags are provided and the air bags are communicated with each other, a stable posture change can be achieved.

Further, in addition to the bottom plate and the upper plate, if two blind plates are used, even if a force to fluctuate in the width direction is generated due to an unbalanced load of the user's weight, the resistance force from the blind plate is increased. Due to, very stable.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on the embodiments shown in the drawings. FIG. 1 is a perspective view of an essential part of a first embodiment of a bedclothes position changing device according to the present invention, and FIG. 2 is a side view of the same embodiment.

In the drawing, the bed posture changing device has a bottom plate 4 and an upper plate 2 rotatable with respect to the bottom plate 4. An air bag 6 is arranged between the bottom plate 4 and the upper plate 2. The materials of the top plate 2 and the bottom plate 4 may be hard ones, for example, plywood. The top plate 2, the bottom plate 4, and the air bladder 6 have a substantially rectangular shape when viewed from above, and are arranged such that the long sides of the rectangular shape extend in the width direction of the bed or the futon.

An extension piece 8 is formed on one side of the air bag 6,
The extension piece 8 is fixed to a rotation fulcrum 10 of the bottom plate 4 and the upper plate 2. An air supply / exhaust air hole 12 is formed in the air bag 6, and an air supply / exhaust hose 14 is connected to the air hole 12.

The supply / exhaust hose 14 is connected to the compressor 20 via a switching valve 22. Switching valve 2
2 is electrically controlled by the control board 16 to switch between air supply and exhaust. The compressor 20 and the control panel 16 are electrically connected to the power supply 18. Further, a controller (not shown) capable of remotely controlling the control panel 16 is provided, and the user operates the controller without directly operating the switch or the like on the control panel 16 so that the upper body angle is 0 to 70. It can be varied over a range of degrees.

Since this embodiment has the above-mentioned structure, when air is supplied to the air bag 6, the two hard upper plates 2 and bottom plates 4 are expanded while being pressed. Therefore, the force from the air bladder 6 is not directly transmitted to the bed or the futon, but is transmitted via the rigid upper plate 2. Therefore, the force transmitted to the bed or the futon becomes substantially uniform over the entire surface of the upper plate 2 and becomes a stable force.

Further, since the extension piece 8 of the air bag 6 is fixed to the rotation fulcrum 10 of the bottom plate 4 and the upper plate 2, the movement of the air bag 6 due to the force exerted by the upper plate 2 is prevented. FIG. 3 is a perspective view of the essential parts of a second embodiment of the bed posture changing device according to the present invention.

When the lengths of the short sides of the top plate 2, the bottom plate 4, the blindfold plate 26, and the blindfold plate 24 are a, b, c, and d, respectively, a to d satisfy the following conditions and are folded. I was able to do it freely.

A + d = b + c Between the bottom plate 4 and the upper plate 2, two air bags 6a, 6b are arranged vertically one above the other. Each air bag 6a, 6b is
Extension pieces 8a and 8b are formed on one side portion of each, and the extension pieces 8a and 8b are fixed to rotation fulcrums of the bottom plate 4 and the upper plate 2.

When inflated, the air bags 6a, 6b are in contact with the top plate 2 and the bottom plate 4 to the vicinity of their tips, and the tips are covered by the blind plate 2.
It is preferable that the size and shape are such that they come into contact with 4, 26. An air supply / exhaust air hole (not shown) is formed in the lower air bag 6a, and the same air supply / exhaust hose as shown in FIGS. 1 and 2 is connected to this air hole.

FIG. 4 is an external perspective view of the embodiment shown in FIG.
In the figure, the openings formed by the top plate 2, the bottom plate 4, the blindfold plate 26, and the blindfold plate 24 are covered with a stretchable woven cloth 27.

In this embodiment, as described above, the air bags 6a and 6b are hidden by the four hard plates and the woven fabric 27 so that they cannot be seen from the outside. Further, by using the four plates in this manner, the blindfold plates 24, 2 are prevented even if a force that fluctuates in the width direction is generated due to an unbalanced load of the user's weight or the like.
Very stable due to twisting resistance from 6.

FIG. 5 is a view showing a state in which the embodiment of FIG. 3 is attached to the bedding 28. When a person lying down on the bed 28 wants to wake up the upper body, air is supplied to the air bag. When the air bag is inflated, the angle between the bottom plate and the upper plate widens, and the state shown in the drawing is obtained. Even if the upper plate is raised up to the maximum angle, the four plates form a quadrangular convex outward.
If you want to recline, exhaust the air bag. When fully evacuated, the top plate is substantially parallel to the bottom plate and the bedding 28 is flat.
