状態で支持される。(Function) First, in a state where each floorboard is supported on a flat surface as shown in FIG. 1(a) and FIG. The link 26 is moved so that its engagement groove 27 does not engage with the drive protrusion of the second drive arm 17, and in this state, the telescopic drive means 33 is operated to connect the drive shaft via the third drive arm 18. When the drive shaft 12 is rotated, the first push-up arm 15 is rotated upward by the rotation of the drive shaft 12, and the back floor plate 3a is rotated upward via the push-up link 19. As the drive shaft 12 rotates, only the first actuating shaft 13 rotates in conjunction with the first drive arm 16, the first drive link 22, and the first interlocking arm 20. Due to the interaction of the operating arm 21, the support rail 6, and the first support link 30, the first support arm 4 moves toward the foot side of the lumbar floor plate 3b or toward the upper right in the figure. Since the back side of the lumbar floor plate 3b is in a free state, it is supported by coming into contact with the upper side of the floor support frame 2 at a proper position, and therefore the lumbar floor plate 3b is inclined upward on the foot side and downward on the back side. On the other hand, as described above, when the foot side of the lumbar floor plate 3b moves to the upper right in the figure, the foot floor plate 3c, which is bendably connected to the lumbar floor plate 3b, also rises. is supported by the action of the second support link 31 in a rotationally lowered state about the connection position C as a fulcrum.

、この腰部床板３ｂは足側方向に移動するので、使用者
の腹部を圧迫しない。In this way, as shown in FIG. 1(b) and FIG. 3(b), the back floor plate 3a rotates upward and at the same time
b rotates downward with the foot side at the top, and the foot floor plate 3c
By rotating and lowering with the end side facing downward, the user on the floorboard can be placed in a gatch position, a reclining position, or a chair-like position. As described above, when the lumbar floor plate 3b rotates downward as the back floor plate 3a rotates upward, the lumbar floor plate 3b moves toward the feet, so it does not press on the user's abdomen.

の駆動腕１８を介して駆動軸１２を回動すると、今度は
前述した第一の作動軸１３と共に、第二の駆動腕１７、
第一の駆動リンク２６並びに第二の連動腕２３を介して
第二の作動軸１４も連動して回動する。従って前述した
通り、背部床板３ａが回動上昇し、腰部床板３ｂの足側

図（Ｃ）に示すように第二の押上腕２４が回動上昇して
腰部床板３ｂを押し上げ、この腰部床板３ｂを、足部床
板３ｃとの連結位置Ｃを支点として回動上昇する。Next, in a state where each floorboard is supported on a flat surface as shown in FIGS. 1(a) and 3(a), the engaging/disengaging means A is operated to connect the second drive link 26. is moved so that its engagement groove 27 engages with the drive protrusion of the second drive arm ]7, and in this state, the telescopic drive means 33 is operated to connect the drive shaft 12 via the third drive arm 18. When rotated, the second drive arm 17, together with the first operating shaft 13 described above,
The second actuating shaft 14 also rotates in conjunction with the first drive link 26 and the second interlocking arm 23 . Therefore, as described above, the back floor plate 3a rotates upward, and the foot side of the lumbar floor plate 3b moves to the upper right in the figure.
As shown in Figure (C), the second push-up arm 24 rotates upward to push up the lumbar floor plate 3b, and the lumbar floor plate 3b rotates upward using the connecting position C with the foot floor plate 3c as a fulcrum.
従って、床部上の使用者は、腰部床板３ｂにより前方側
に腰を持ち上げられ、寝台からの立上りを補助される。Therefore, the user on the floor has his/her waist lifted forward by the lumbar floor plate 3b, and is assisted in getting up from the bed.
この際、足部床板３ｃは、端側の一部を、上方にのみ回

れる。In the above configuration, first, each floor plate is as shown in Figure 1(a).
, when the second drive link 26 is moved upward by operating the engagement/disengagement means A in a state where it is supported on a plane as shown in FIG. 3(a), the engagement groove 27 is opened. It is in a state where it does not engage with the drive protrusion 28 of the second drive arm 17. In this state, the telescopic drive means 33 is operated to move the third drive arm 18.
When the drive shaft 12 is rotated clockwise in the figure via the drive shaft 12, the first push-up arm 15 is rotated upward by the rotation of the drive shaft 12, and the back floor plate 3a is rotated upward via the push-up link 19. . As the drive shaft 12 rotates, only the first actuating shaft 13 rotates in conjunction with the first drive arm 16, the first drive link 22, and the first interlocking arm 20. Due to the interaction of the operating arm 21, the support rail 6, and the first support link 30, the first support arm 4 moves toward the foot side of the lumbar floor plate 3b or toward the upper right in the figure. Since the back side of the lumbar floor plate 3b is in a free state, the roller as the contact support member 8 is supported by contacting the upper side of the support rail 6, so that the lumbar floor plate 3b is tilted upward on the foot side and downward on the back side. do. on the other hand,
As described above, by moving the lumbar floor plate 3b to the foot side or to the upper right in the figure, the foot floor plate 3C, which is flexibly connected to the lumbar floor plate 3b, also rises. Due to the action of the second support link 31, it is supported in a state in which it is rotated downward in a clockwise direction using the connection position C as a fulcrum.

b rotates downward with the foot side at the top, and then the foot floor plate 3C
By rotating and descending with the end side facing downward, the user on the floorboard can be placed in a grab position, a reclining position, or a chair-like position. As described above, when the lumbar floor plate 3b rotates downward as the back floor plate 3a rotates upward, the lumbar floor plate 3b moves toward the feet, so it does not press on the user's abdomen.

Rotate the shaft 12. This time, the engagement rPt27 of the second drive link 26 and the drive protrusion 28 of the second drive arm 17 engage, so that the second drive arm 17 and the second drive The second operating shaft 14 also rotates in conjunction with the link 26 and the second interlocking arm 23. Therefore, as described above, the back floor plate 3a rotates upward and moves to the foot side of the lumbar floor plate 3b or to the upper right in the figure, and at the same time as shown in FIGS. 1(C) and 3(c).
As shown in , the second push-up arm 24 rotates upward to push up the lumbar floor plate 3b, and the lumbar floor plate 3b is rotated upward about the connection position c with the foot floor plate 3C as a fulcrum.
従って、床部上の使用者は、腰部床板３ｂにより前方側
に腰を持ち上げられ、寝台からの立上りを補助される。Therefore, the user on the floor has his/her waist lifted forward by the lumbar floor plate 3b, and is assisted in getting up from the bed.

Since the length of the foot floor plate 3c is substantially shortened, the user's feet can reliably reach the floor surface. As mentioned above, in the present invention, a drive source such as an electric motor is used for the above-mentioned engaging/disengaging means A, but this drive source simply moves the above-mentioned second drive link 26. Since there is no need to withstand a large load, a small capacity one is sufficient.
Therefore, there is little effect on increases in the space required, weight, price, etc. of the mechanism.

Despite having both functions that can assist in standing up, these drive sources are unified and the drive system is configured to a minimum, resulting in smaller space requirements, lighter weight, and lower prices. The effect is that it can be done.
