Due to the meshing with the intermediate gear 31 and the first gear 2
9 and 30 to drive the pinion 30, the rack 35 is pulled back to retract the pantograph 23 as shown in FIG. When the meshing with the second gear 33 is released, the teeth of the partially toothed gear 28 and the gear 37 start to mesh and together drive the pinion 38. When the slide frame 4 is slid in the direction and the lid body 5 faces directly below the through hole 3, the meshing between the teeth of the partially toothed wheel 28 and the gear 37 is released.

When the teeth of the partially toothed gear 28 that continues to rotate mesh with the second gear 34 as shown in FIG. 12, the pinion 36 is driven through the second gear 34, the intermediate gear 32, and the first gear 30. Therefore, slide the slider 26 while pushing back the rack 35.

As a result, the pantograph 23 is extended, and when the extension of the pantograph 23 reaches a set length, the operation of the motor 27 is stopped.

Note that instead of the above configuration, the slide frame 4 and the elevating body B may be operated by separate motors or the like.

In the figure, 43 is a lid that can be opened and closed.

The bed with a toilet bowl according to the present invention has the above-mentioned structure, and its operation will be explained next. When the motor 27 is operated during excretion, it drives the gear toothed wheel 28 in the counterclockwise direction in FIG. Missing gear wheel 28
The teeth of and the second gear 34 mesh to form the intermediate gear 3.
2. Since the pinion 36 is rotated through the first gear 30, the slider 26 is pulled back together with the rack 35, and the elevating body B is lowered.

Therefore, the engagement between the protruding strip 12 and the holding member 13 causes the lid 5 to be pulled down so that it comes out of the through hole 3, and the mounting seat of the lid 5 is attached to one end of the slide frame 4 as shown in FIG. Place the plate 7.

At this time, the protrusion 9 fits into the through hole 10.

As the above-mentioned partially toothed wheel 28 continues to rotate, the teeth of the partially toothed wheel 28 and the gear 37 mesh with each other to rotate the pinion 38, so that the slide frame 4 slides via the rack 40. .

For this purpose, the lid 5 is placed on the side edge of the bed A, and the potty 6 is moved directly below the through hole 3.

At this time, the holding member 13 of the seat plate 8 is fitted into and locked with the protruding strip 12 of the plate-shaped body 11, and the elevating body B and the mounting seat plate 8 of the potty 6 are integrated.

When the teeth of the partially toothed wheel 28 come off from the gear 37, the sliding of the slide frame 4 is stopped as shown in FIG. Because they mesh, intermediate gear 3
1. Rotate the pinion 36 through the first gears 29 and 30.

Therefore, while pushing back the slider 26 together with the rack 35 and raising the elevating body B, the potty 6 is fitted into the through hole 3 as shown in FIG.

When the above-mentioned fitting of the potty 6 is completed, the meshing between the teeth of the partially toothed wheel 28 and the second gear 33 is released.

The motor 27 is stopped by bringing the end of the rack 35 into contact with the limit switch 44.

When the motor 27 is operated after excretion is completed, the first
Since the toothed gear wheel 28 is rotated in the direction of the arrow in figure 0,
The second gear 33 and the teeth of the partially toothed gear 28 begin to mesh, and the pinion 36 rotates through the intermediate gear 31 and the first gears 29 and 30, and the elevating body B is lowered together with the rack 35. let

Therefore, the potty 6 is pulled down by the engagement between the protruding strip 12 and the holding member 13, and the seat plate 8 is placed on the upper end of the slide frame 4.

At this time, the protrusion 9 fits into the through hole 10, and the slide frame 4 and seat plate 8 are engaged with each other.

At the end of the descent of the elevating body B, the meshing between the teeth of the partially toothed wheel 28 and the second gear 33 is released, the gear 37 meshes with the teeth of the partially toothed wheel 28, and the rotation of the pinion 38 causes the gear to be easily lifted. Since the slide frame 4 is slid through the slide frame 40, the potty 6 is moved toward the side edge of the bed A, and the lid 5 is moved toward the bottom of the through hole 3.

When the meshing between the teeth of the partially toothed wheel 28 and the gear 37 is released, the through hole 3
The sliding of the slide frame 4 stops when the lid body 5 faces directly below.

At this time, the holding member 1 of the seat plate 7 is attached to the protruding strip 12.
3 is inserted and engaged.

After that, the teeth of the second gear 34 and the partially toothed gear 28 begin to mesh, and the pinion 36 rotates through the intermediate gear 32 and the first gear 30, pushing the slider 26 back together with the rack 35. Lifting body B

Therefore, the lid 5 is fitted into the through hole 3.

The above-mentioned potty 6 is removed by rotating it on the seat plate 8 (as shown in FIG. 2) to disengage the notch 41 and pin 42, and the waste inside the potty 6 is discarded.

The washed potty 6 is set on the seat plate 8 (the pin 42 and the notch 41 are engaged).

Further, by replacing the seat plates 7 and 8 on the slide frame 4, the position at which the potty room 6 is taken out can be changed.

As described above, according to the bed with a toilet according to the present invention, while the slide frame is moved back and forth between both sides of the bed, the lid body on both ends of the slide frame and the potty are placed under the through hole provided in the bedding. In addition to replacing the
Since the lid and the potty are alternately fitted into the through-hole by the elevating body, a person lying on the bed can defecate while lying down.

In particular, since the potty is placed so that it reaches the side edge of the bed, the problem is that when taking out the potty, you have to bend over and put your head in the narrow space under the bed, which causes lower back pain due to the awkward posture. can be resolved.

Furthermore, by replacing the seat plates on the slide frame, the position at which the potty is taken out can be changed.

Therefore, there are no restrictions on the arrangement of the bed (with one side of the bed close to the wall).
