DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIGS. 1 and 2, reference numeral 4 denotes a space between a mat 3 and a floor (including a tatami mat) 5 (FIG. 7), and a patient 2 lying on the mat 3 (FIG. 7). FIG. 6 shows a raising device interposed in a portion corresponding to the upper body of the mat, 6 is a support means for supporting a portion of the mat 3 corresponding to the patient's upper body, and a frame 7 formed by bending a metal pipe into a U-shape; The back member 8 is made of a wooden or resin plate, cloth, mesh, or the like fixed to the frame 7. An opening 9 is formed in a lower portion of the back member 8, that is, a portion corresponding to the patient's waist of the mat 3. The opening 9 allows the mat 3 to be bent and enter the patient's weight when the support means 6 is raised. Therefore, as shown in the drawing, it is usually sufficient to simply use the open portion 9, but in consideration of safety, a mat-shaped sheet is attached so that the mat 3 does not sink abnormally, and the mat 3 does not sink more than a predetermined amount. It can also be structured. Reference numeral 10 denotes a substrate means to be placed on the floor, which is a frame 11 obtained by bending a pipe made of Kintaka into a U-shape, a wooden or resin substrate 12 stretched over the frame 11, and a portion near the tip of the frame 11. And a reinforcing member 13 formed on the substrate.

Reference numeral 14 denotes a hinge connecting plate. As shown in FIG. 3, the upper end is hinged to the lower end of the frame 7 via a stopper 15, and the lower end is connected to a stopper 16 near the front end of the frame 11 via a stopper 16. Have been. 17,
Reference numeral 18 denotes a hinge shaft, and reference numerals 19 and 20 denote first and second contact portions formed at both ends of the hinge connection plate 14, which contact the stoppers 15 and 16 when the hinge connection plate 14 rotates a predetermined angle. These stoppers 15, 16 are hinged shafts 17, 1
8 restricts the maximum rotation angle. When the stoppers 15 and 16 and the hinge connecting plate 14 abut at two places, the loads applied to the abutting portions 19 and 20 are dispersed, and the hinge shafts 17 and 18 are disengaged.
It functions to prevent deformation and breakage of the portion and to suppress the frame 7 from swaying left and right. The other hinge shaft 1
The eight parts also have the same structure. Hinge connecting plate 14
The hinge shafts 17 and 18 constitute a hinge means.

Reference numeral 21 denotes an airbag disposed between the front surface of the substrate 12 and the back surface of the back member 8, as shown in FIG.
It is composed of a pair of left and right bellows-shaped airbag portions 21a, 21b. The upper and lower ends of the airbag portions 21a and 21b are respectively abutted or fixed between the back member 8 and the substrate 12, and the front and rear surfaces thereof have a pair of elongated sheet pieces 22, Reference numeral 22 is welded to each bellows-shaped portion (the welded portion is indicated by a dotted line p in FIG. 4), so that the interval between the tips of the bellows portion does not expand beyond a certain value.
The sheet pieces 22 and 22 function as means for restricting the inflation of the airbag 21. The sheet pieces 22, 22 can be formed of the same material as the airbag 21.

Reference numeral 23 denotes a front sheet piece 22 and a reinforcing member 1.
3, a tension wire made of a piano wire stretched between
It functions as a means for regulating the direction of inflation of the airbag 21. One end of the tension wire 23 is fixed to fixing points 24, 24 near both ends of the reinforcing material 13, and the other end is fixed to the sheet piece 22, and the sheet piece 22 is connected to the two tension wires 23. It is connected to the reinforcing member 13 and its movement in the front-rear and left-right directions is restricted, and it is possible to move only in the turning direction. The tension line 23 is provided at an intermediate portion between the airbag portions 21a and 21b, for example, the airbag portion 21.
a and 21b are connected to the third and sixth stages. The fixed point 24 is arranged at a position near the center of rotation of the frame 7. Therefore, the airbag 21 inflates along a circumference close to the circumference around the center of rotation of the frame 7.

The sheet piece 22 is provided with the airbag portions 21a, 21a.
1b, that is, the maximum rotation angle of the back member 8 is regulated. Although the maximum rotation angle of the back member 8 is also restricted by the maximum rotation angle of the hinge shafts 17 and 18, when a force is applied to the frame 7 or the back member 8 to further raise the same, An excessive force is applied to the hinge shafts 17 and 18 due to the leverage, and there is a possibility that the hinge shafts 17 and 18 may be deformed or damaged. Therefore, it is necessary to protect the hinge shafts 17 and 18. In order to regulate the maximum rotation angle, the stoppers 15 and 16 and the abutting portions 19 and 2 of the hinge connecting plate 14 are required.
This is because a high dimensional accuracy is required to be zero, and it is difficult to obtain a maximum rotation angle that is stable in terms of quality in practice.

The bellows-like portions of the airbag portions 21a and 21b are obtained by cutting a flexible sheet having air impermeability into a rectangular shape, stacking two of them, and welding the periphery to form a sealed structure. It becomes almost elliptical in cross section at the time of air supply. As this sheet material, PVC resin or PU is applied to nylon woven fabric.
Sheets coated with resin can be used. As the woven fabric, in addition to nylon, polyester woven fabric and aramid woven fabric can be used. As shown in FIG. 6, the periphery q of the hole 25 slightly inside the center and the periphery r of the sheet are welded, and the sheet piece 22 is also welded to the portion r around the sheet. A plurality of bellows-like portions are stacked, for example, eight stages. In such a structure, the airbag portions 21a and 21b are integrated, but it is also possible to provide a detachable joint at the hole 25 portion so that each bellows-like portion can be divided. In such a case, when one bellows-shaped part is broken, there is an advantage that only that part can be replaced.

Reference numeral 26 denotes an air pump that is driven by a commercial AC power supply and supplies or exhausts air to and from the airbag 18, and is connected by a hose 27. Reference numeral 28 denotes a plug inserted into the AC power supply. Airbag 21 and air pump 2
7 constitutes a driving means. 29 is frame 7,1
A bellows-shaped protective cover attached between the two, which expands and contracts as the frame 7 rotates.

Reference numeral 30 denotes a leg airbag, which is positioned below a portion corresponding to a leg, particularly a knee, of the patient 2 lying on the mat 3. Reference numeral 31 denotes a side airbag which communicates with the leg airbag 30 and is disposed in a pair corresponding to the left and right hips of the patient 2. Air is supplied to and exhausted from the air pump 26 through the hose 27 to the leg airbag 30 and the side airbag 31. The leg airbag 30 and the side airbag 31 are formed integrally with a seat 32, and the seat 32 is fixed to the reinforcing member 13 with a band 33 such as a planar fastener.

Normally, the airbag 21, the leg airbag 3
The 0 and side airbags 31 are simultaneously inflated and driven, and when the patient 2 rises, the knees are also raised to make the upright posture easy, and the upper body is inflated by the inflation of the side airbags 31. Prevents falling from side to side, and stabilizes the standing posture. However, it is also possible to provide a structure in which each of the above parts is independently supplied and exhausted so that each part can be selectively driven. In such a case, each airbag is supplied and exhausted with an independent hose. In addition, the mat 3 can use an air mat other than a normal mattress,
The air pump 26 can also be used for the air supply. In this case, the air mat 3 needs to be driven independently of the other airbags 21 and the like, and the air pump 26 has a built-in control unit for controlling the supply and exhaust of the air.

The operation of the rising device 4 having the above structure will be described with reference to FIG. First, the frame 7 of the support means 6
Are in the horizontal direction, so that the mat 3 is also in a horizontal state. When the air pump 26 (FIG. 1) is driven to start supplying air to the airbag 21, the frame 7 and the back member 8 gradually rise (leftward rotation) due to the expansion of the airbag 21. The inflation operation of the airbag 21 is limited by the sheet piece 22 and the tension line 23 and inflates as if drawing an arc. At the beginning of the rising, the hinge shaft 17 located at the rear is rotated to a predetermined angle, for example, about 3 degrees.
It turns five degrees and hits the stopper-15. Airbag 2
When the valve 1 is further expanded, the hinge shaft 18 located at the front starts to rotate, and rotates up to about 35 degrees. In this case, at the hinge axis 17.18, the frame 7
And the back member 8 can be raised.

This maximum rotation angle is also restricted by the sheet piece 22 of the airbag 21. By controlling the driving of the air pump 26, the patient 2 or the caregiver can raise the patient at an arbitrary angle within this angle range. The rotation angles of the hinge shafts 17 and 18 can be set in a range of about 10 to 45 degrees, respectively, and thus, about 20 to 9 in total.
A rising angle in the range of 0 degrees is obtained, in which case the length of the sheet piece 22 is adjusted accordingly. Hinge shaft 17, 1
8 has a two-stage structure in order to bend the waist with a gentle curve, that is, with a curve similar to the curvature of the lumbar region and the spine so as not to apply excessive force to the human body.

As the back member 8 rises, the mat 3 is pressed backward as indicated by the arrow b in accordance with the bending of the waist of the patient 2. The pressed mat 3 is pressed by the opening portion 9 below the back member 8 in response to the force, and enters into the opening portion 9 to bend. Therefore, an unpleasant force (indicated by an arrow a in FIG. 10) that compresses the lumbar region of the patient 2 does not occur, and the lumbar region and the spine draw a natural S-shaped curve. Get up posture.

FIGS. 8 and 9 show another embodiment of the hinge means. Two hinge plates 34 and 35 are formed with two hinge shafts 36, 37, 38 and 39, respectively. As it intersects axes 36, 37, 38, 39,
That is, two hinge connecting plates 40 and 41 connecting the hinge shafts 36 and 39 and the hinge shafts 37 and 38 are connected. The rear hinge plate 34 is connected to the frame 7 of the support means 6 of the above-described embodiment, and the front hinge plate 34 is connected to the substrate means 10. When the frame 7 is rotated by the inflation of the airbag 21, the two hinge plates 34, 3
5 rotates simultaneously by the same angle from the beginning. Therefore, the bending operation of the frame 7 with respect to the substrate means 10 is made more natural and gentle. In such a configuration, the hinge shaft portion is not provided with a stopper for regulating the maximum rotation angle. This angle regulation is performed only by the sheet piece 22 in the above-described embodiment.
