〔Example〕

The bed body A in the drawing has a back support frame 1 with a length corresponding to the length from the patient's head to the waist, and a hip support frame 2 with a length corresponding to the length from the waist to the knees at the rear of the waist side. A leg support frame 3 is bendably connected to the rear part of the leg support frame 2 on the knee side, and a foot support frame 4 is foldably connected to the rear part of the leg support frame 3 on the base side of the foot. The base frame 9 is integrally formed in the front part of the hip support frame 2, and each component frame of the back support frame 1, the hip support frame 2, the leg support frame 3, and the foot support frame 4 is configured to be pivotally connected in a flexible manner. Above, bent base edge 10
The case is shown in which bed mats 7 connected to each other and formed to have the required area and thickness are placed.

This will be explained in more detail.

In the drawing, connecting pieces 11 slightly lower than the upper surface of the bed mat 7 are erected on the left and right sides of the opposing ends of the back support frame 1 and the back support frame 2, respectively, and the overlapping part near the upper edge of the connecting pieces 11 is connected to the pivot shaft. 12, the left and right sides are connected and pivoted, and the knee-side rear part of the leg support frame 3 is attached to the bent base edge 1 of the bed mat 7 on both left and right inner surfaces of the knee-side rear part of the hip support frame 2.
Pivotally connected by the pivot shaft 12 at the position near 0, and the leg support frame 3
Connecting pieces 11' slightly lower than the upper surface of the bed mat 7 are provided on the left and right sides of the opposite ends of the footrest frame 4, and the overlapping portions of the connecting pieces 11 near the upper edges are connected to the left and right by a pivot shaft 12'. A lifting motor 13 and a lifting motor 14 which are connected and pivoted and can rotate in forward and reverse directions are attached to the lower part of the head side of the base frame 9 via brackets 15, respectively, and the main shafts of the lifting motors 13 are connected to each other by a screw mechanism a. The tip of a long telescopic rod 16 which is connected and expands and contracts with the forward and reverse rotation of the lifting motor 13 is pivotally connected to the lower part of the bent part side of the front leg support frame 3 via the link piece 17, and is connected to the lower part of the base frame 9. A regulating link rod 19 is pivotally installed at the center and the lower part of the footrest frame 4 via a regulating link piece 18, and the telescopic rod 16
The length of the leg support frame 3 and the length of the regulating link rod 19 are adjusted so that the leg support frame 3 bends between the horizontal position and the downwardly inclined position by the telescopic movement of the telescopic rod 16 caused by the rotation of the lifting motor 13. When the footrest frame 4 is configured to have a length that allows it to move up and down in a substantially horizontal state,
Further, the tips of short telescopic rods 20, which are connected to the main shafts of the hoisting motors 14 by a screw mechanism a and extend and contract with forward and reverse rotations of the hoisting motors 14, are connected to the lower part of the back support frame 2 side of the back support frame 1 with a link piece. 21, and the inclination of the back support frame 1 is adjusted by the telescopic operation of the telescopic rod 20 by the levitating motor 14.

In addition, a bed mat 7 is placed on the upper surface of the back support frame 1, hip support frame 2, leg support frame 3, and foot support frame 4 that constitute the bed body A, and this bed mat 7 is attached to each of the component frames 1, 2, 3, and 4. The case is shown in which the mat is designed to be bent at the bent part and is attached with a piece that connects the bent base edges 10, but each component frame 1 has a separate mat body as the bed mat 7. , 2, 3, and 4.

Since this embodiment has the above-mentioned configuration, when the lifting motor 13 is rotated by a push button switch or the like in a normal bed usage condition as shown by the imaginary line in FIG. As a result, the leg rest frame 3 swings downward about the pivot shaft 12, and at this time, the leg rest frame 4 is lowered by the regulating link rod 19 while maintaining a substantially horizontal state, and the first It stops at the solid line position in the figure.

Furthermore, when the lifting motor 13 is reversely rotated, the telescopic rod 16 is extended by the screw mechanism a, and the first
It returns to its normal flat state as shown by the imaginary line in the figure.

Furthermore, when the raising and lowering motor 14 is rotated using a push button switch or the like, the telescopic rod 20 similarly performs a contraction movement, and the back support frame 1 swings upward around the pivot shaft 12, changing from the imaginary line in FIG. 1 to the solid line. If you stand up and rotate it in the opposite direction, it will return to its normal flat state.

Further, in this embodiment, a toilet bowl 22 is installed in the part of the buttocks support frame 2 that corresponds to the patient's buttocks, as shown by the imaginary line in FIG.

[Effect of idea]

Since the present invention is constructed as described above, when the lifting motor 13 is rotated by a push button switch or the like in a normal bed usage condition as shown by the imaginary line in FIG. As a result, the leg support frame 3 moves toward the pivot shaft 1.
At this time, the footrest frame 4 is lowered by the regulating link rod 19 while maintaining a substantially horizontal state, and stops at the position shown in the solid line in FIG.

Furthermore, when the lifting motor 13 is reversely rotated, the telescopic rod 16 is extended by the screw mechanism a, and the first
It returns to its normal flat state as shown by the imaginary line in the figure.

Furthermore, when the raising and lowering motor 14 is rotated using a push button switch or the like, the telescopic rod 20 similarly performs a contraction movement, and the back support frame 1 swings upward around the pivot shaft 12, changing from the imaginary line in FIG. 1 to the solid line. If you stand up and rotate it in the opposite direction, it will return to its normal flat state.

In addition, since the lower ends of the leg rods that are vertically installed on the outer left and right ends of the buttrest frame are connected to the floor support legs that are bent in an L shape toward the legrest frame, the fulcrum is close to the point of force when levering. This makes it possible to create a safe and practical bed for the sick and the elderly that does not lift up even when a nurse puts their foot on the footrest that is lowered from the bed.
