Reference numeral 72 shown in FIG. 11 is provided in the upper member 2, and a second allowable passage that allows the third motor 7 to move along the movement of the third motor 7 toward the second motor 6. Thus, it corresponds to the second guide passage 62. A bolt V is attached to the third rotary shaft 13 via a washer W on the second allowable passage 72.

また、図４に示す６３は、ベース１の上に設けられ、第２のモータ６が第１のモータ５に向かう移動を案内する両側に壁６３ａ、６３ａを有する第３の案内通路で、第３の案内通路６３は、第３の案内通路６３の両側の壁６３ａ、６３ａにより、台座６ａが第２の回転軸１２と共につれ回りしないように、台座６ａの回動を規制している。

The third guide passage 63 restricts the rotation of the pedestal 6 a by the walls 63 a and 63 a on both sides of the third guide passage 63 so that the pedestal 6 a does not rotate with the second rotating shaft 12.
Further, reference numeral 73 shown in FIG. 11 is provided in the upper member 2, and a third allowable passage that allows the second rotating shaft 12 to move following the movement of the second motor 6 toward the first motor 5. Thus, it corresponds to the third guide passage 63. A bolt V is attached to the second rotary shaft 12 via a washer W on the third allowable passage 73.

また、図４に示す６４は、ベース１の上に設けられ、第３のモータ７が第４のモータ８に向かう移動を案内する両側に壁６４ａ、６４ａを有する第４の案内通路で、第４の案内通路６４と第２の案内通路６２とは連通している。第４の案内通路６４は、第４の案内通路６４の両側の壁６４ａ、６４ａにより、台座７ａが第３の回転軸１３と共につれ回りしないように、台座６ａの回動を規制している。
また、図１１に示す７４は、上方部材２に設けられ、第３のモータ７が第４のモータ８に向かう移動に追随して第３の回転軸１３の移動を許容する第４の許容通路で、第４の案内通路６４に対応するものである。第４の許容通路７４と第２の許容通路７２とは連通している。
そして、第１、第２、第３、第４のモータ５、６、７、８及びモータ４７の正逆の回転方向、回転数（停止含む）は、制御手段１００により制御される。 4 is a fourth guide passage provided on the base 1 and having walls 64a and 64a on both sides for guiding the movement of the third motor 7 toward the fourth motor 8. The four guide passages 64 and the second guide passages 62 communicate with each other. The fourth guide passage 64 regulates the rotation of the pedestal 6 a by the walls 64 a and 64 a on both sides of the fourth guide passage 64 so that the pedestal 7 a does not rotate with the third rotation shaft 13.
Further, 74 shown in FIG. 11 is provided in the upper member 2, and a fourth allowable passage that allows the movement of the third rotating shaft 13 following the movement of the third motor 7 toward the fourth motor 8. Thus, it corresponds to the fourth guide passage 64. The fourth allowable passage 74 and the second allowable passage 72 communicate with each other.
The control means 100 controls the first, second, third, and fourth motors 5, 6, 7, 8 and the motor 47 in the forward and reverse rotational directions and the rotational speed (including stoppage).

従って、例えば、制御手段１００により第１、第２、第３、第４のモータ５、６、７、８を個々に制御して、ベッド本体４を水平状態にする。そして、制御手段１００により第１、第２、第３、第４のモータ５、６、７、８を同期させて、回転させれば、水平状態のベッド本体４を適宜の高さ位置に調整することができる（図２参照）。
また、制御手段１００により第１の回転軸１１に螺合する第１の雌ネジ体２１及び第２の回転軸１２に螺合する第２の雌ネジ体２２が上昇するように第１、第２のモータ５、６を回転させると共に、第３の回転軸１３に螺合する第３の雌ネジ体２３及び第４の回転軸１４に螺合する第４の雌ネジ体２４が下降するように第３、第４のモータ７、８を回転させれば、被介護者の頭が足より高い位置になるようにベッド本体４が立ち上がる（図９参照）。その結果、被介護者がベッド本体４から立った状態で移動することができる。 Therefore, for example, the first, second, third, and fourth motors 5, 6, 7, and 8 are individually controlled by the control means 100, and the bed body 4 is brought into a horizontal state. If the first, second, third, and fourth motors 5, 6, 7, and 8 are synchronized and rotated by the control means 100, the bed body 4 in the horizontal state is adjusted to an appropriate height position. (See FIG. 2).
In addition, the first female screw body 21 screwed to the first rotary shaft 11 and the second female screw body 22 screwed to the second rotary shaft 12 are raised by the control means 100 so as to rise. The second motors 5 and 6 are rotated, and the third female screw body 23 screwed to the third rotary shaft 13 and the fourth female screw body 24 screwed to the fourth rotary shaft 14 are lowered. In addition, if the third and fourth motors 7 and 8 are rotated, the bed body 4 rises so that the head of the cared person is positioned higher than the feet (see FIG. 9). As a result, the cared person can move while standing from the bed body 4.

また、ベッド本体４から立った状態から、制御手段１００により第１の回転軸１１に螺合する第１の雌ネジ体２１及び第２の回転軸１２に螺合する第２の雌ネジ体２２が下降するように第１、第２のモータ５、６を回転させると共に、第３の回転軸１３に螺合する第３の雌ネジ体２３及び第４の回転軸１４に螺合する第４の雌ネジ体２４が上昇するように第３、第４のモータ７、８を回転させて、ベッド本体４が水平方向になるように調整す。その後、制御手段１００により第１の回転軸１１に螺合する第１の雌ネジ体２１及び第４の回転軸１４に螺合する第４の雌ネジ体２４が上昇するように第１のモータ５及び第４のモータ８を回転させ（図１２の二点鎖線のベッド本体４参照）、
逆に、図示しないが、制御手段１００により第１の雌ネジ体２１及び第４の雌ネジ体２４が下降するように第１のモータ５及び第４のモータ８を回転させて、被介護者を左右に回動させて、被介護者の圧迫する部位を変化させて、床ずれをも防止することができる。 Further, from the state of standing from the bed main body 4, the first female screw body 21 screwed to the first rotary shaft 11 and the second female screw body 22 screwed to the second rotary shaft 12 by the control means 100. The first and second motors 5 and 6 are rotated such that the first and second motors 5 and 6 are lowered, and the third female screw body 23 and the fourth rotating shaft 14 are screwed together. The third and fourth motors 7 and 8 are rotated so that the female screw body 24 rises, and the bed body 4 is adjusted to be in the horizontal direction. After that, the first motor so that the first female screw body 21 screwed to the first rotating shaft 11 and the fourth female screw body 24 screwed to the fourth rotating shaft 14 are raised by the control means 100. 5 and the fourth motor 8 are rotated (see the bed main body 4 of the two-dot chain line in FIG. 12),
Conversely, although not shown, the control means 100 rotates the first motor 5 and the fourth motor 8 so that the first female screw body 21 and the fourth female screw body 24 descend, and the cared person Can be rotated to the left and right to change the part to be pressed by the care recipient, thereby preventing bed slippage.
