There is a length, and the beauty of the rising edge of the bathtub 13 is improved. Note that it is also possible to fix the side sheet edges so as to cover the upper frame 4 at intervals, and to use the upper frame 4 also as the rising edge of the bathtub 13. Further, since the tubular portion 18a at the edge of the sheet 18 is for inserting the pipe-shaped shaping arm 19, a ring-shaped band may be attached at an interval instead of the tubular portion 18a. In addition, connecting rope 20
Since the required seat length changes depending on the inclined state of the backrest 7b, it is fastened to the frame 2 later. When the seat 18 is formed into a bathtub shape, an engaging means is provided between the edge of the seat 18 and the upper frame 4 to support the upper portion of the bathtub shape in order to maintain the height.

Next, a case where the care bed 1A is used as a bath will be described with reference to FIG. First, the seat 18 is inserted between the user and the bed mat 8 while slightly changing the direction of the user on the bed mat 8 and moving, and the position of the seat 18 is adjusted. At this point, it can be used as a bed with the sheet 18 laid. Next, the electric motor 11 is driven, and the plate 7 is lowered while the belt 9 is being fed out.
, And the electric motor 11 is stopped. At this time, since the sheet 18 becomes concave, hot water is poured at the same time. Then, the backrest 7b and the inner leg 7c are tilted by operating another driving means so that the user can take a comfortable posture. In this state, the edge of the seat 18 and the shaping arm 19 are fixed, and the backrest 7 b side of the seat 18 is stretched by the connecting rope 20. When the above procedure is completed, it can be used as a bathtub.

Therefore, the bathtub 13 is formed by simply lowering the bed surface (plate 7). However, the mechanically movable parts such as the electric motor 11 are separated from the inside of the bathtub 13 by the seat 18, and lubrication and rusting are performed. Is also solved, and the inside of the bathtub 13 is kept clean. Further, since the sheet 18 constituting the bathtub 13 can be washed and dried at a position different from the bed (frame 2), the cleanliness of the bathtub 13 is improved. Further, when transporting the care bed 1A and the bathtub parts of the present invention, since the sheet 18 of the bathtub parts is folded, the loading / unloading work becomes easy, and the installation work also becomes simple. After using the nursing bed 1A as the bathtub 13, the hot water in the seat 18 is drained, and after keeping the user warm, the motor 11 is operated to raise the plate 7. And bed mat 8
The seat back is flattened, the bed surface is returned to the original use position, and the seat 18 is removed. Thereby, the care bed 1A is used as a bed. It should be noted that a pump may be used to drain hot water from the sheet 18, or a plug may be provided at a location located on the bottom surface of the sheet 18 and discharged from there. Further, if the plurality of support members 21 are changed in height and the floor surface (plate 7) is inclined, discharge becomes easy.

Next, another embodiment will be described with reference to FIGS. First, the plate 7 on which the bed mat 8 is placed is supported by a pair of support feet 22, and the support feet 22 are rotatably provided by the electric motor 11 and are stopped at predetermined positions. The sheet 18 used as a bathtub has a bottomed cylindrical shape. Compared with the above-mentioned sheet 18 (FIG. 2), there is no portion corresponding to the hatched portion p, and the four corners are previously subjected to a joining process (waterproof sewing, etc.). . Also, sheet 1
The upper end of 8 is provided with a cylindrical (ring-shaped) engaging portion 24 so that a rigid plate 23 having a rectangular cross section can be attached and detached in three directions. Further, the rigid plate 23 is provided with an engagement groove 23 a so as to be fixed at a right angle to each other, and a corner (end) of the rigid plate 23 is connected to the column 3 by a connecting rope (wire) 20. Further, the shape of the sheet 18 is cylindrical with a bottom, but since the sheet 18 is a uniform cloth, the lower portion can be expanded in an arc shape. However, the bottom surface is flat because it is supported by the bed mat 8. Further, the periphery has an extended length to form the bathtub wall, and this portion is zigzag folded in the height direction.

Next, how to use a bed or a bath tub made of sheets on the bed will be described. When the bed is used as a bed, as shown in FIG. 4, the bed mat 8 can be set to a height H or a height L so as to be in a normal use position.
