部として構成している。First, in the figure, reference numeral 1 indicates a bed frame,
A back floor plate 2a is rotatably supported on the bed frame 1 and is rotated and raised and lowered by a drive mechanism A. Reference numeral 3 indicates a support portion, that is, a rotation fulcrum. In the figure, a drive mechanism A is composed of a push-up arm 4 protruding below the back floor plate 2a, a telescopic rod formed between the push-up arm 4 and the bed frame 1, and a drive source 17 thereof. There is.
As the expansion / contraction rod 5, a mechanism using a screw shaft and a nut member as shown in the figure can be used, and an appropriate mechanism such as a mechanism using a hydraulic cylinder or a mechanism using a gas spring can be applied. Also, the drive mechanism A itself has a structure in which a gas spring is directly connected between the back floor plate 2a and the bed frame 1 without providing the push-up arm 4, and the push-up arm 4 is rotatably and vertically movable to the bed frame 1 side. An appropriate mechanism such as the above configuration can be used. Below the back floor plate 2a on the side of the rotation fulcrum 3, a pair of support arms 6 are provided in the width direction, the support arms 6 having their front ends protruding toward the waist. Reference numeral 7 is a waist support frame, and one side of the waist support frame 7 is connected to and supported by the tip end portion of the support arm 6, and the other side is a floating link 8 rotatably supported by the bed frame 1. It is connected and supported. In the figure, the floating link 8 is configured such that, in a state in which the back floor plate 2a is not rotated and raised, the connecting portion on the waist supporting frame 7 side is closer to the foot than the connecting portion on the bed frame 1 side. However, its position is appropriate. Further, the waist support frame 7 is provided with a pair of groove-shaped guide frames 9 whose opening sides are opposed to each other corresponding to the longitudinal direction of the bed frame 1, and is movably engaged with the guide frames 9. By providing the support roller 10 on the waist floor plate 2b and movably engaging the support roller 10 with the guide frame 9, the waist floor plate 2b is moved to the waist support frame 7
Is supported on the upper side of the bed frame 1 so as to be movable in the longitudinal direction of the bed frame 1. Reference numeral 11 is a support frame of the support roller 10, and the support frame 11 is fixed to the waist floor plate 2b. Next, the reference numeral is the foot floorboard 2c.
It is flexibly connected to the foot side of 2b. Also the foot floorboard 2c
A moving roller 12 is provided at the end of the. Reference numeral 13 is an actuating link, and a pair of actuating links 13 are provided in the width direction and connected between the waist floor plate 2b and the back floor plate 2a at appropriate positions.
In the figure, the actuation link 13 is bent so that the intermediate portion 14 is located below, and the intermediate portion 14 is configured as a support portion for the mattress receiver 15.

できる。In the above structure, the back floor plate 2a is moved from the state shown in FIG. 2 (c) to (b) through (a) by extending the telescopic rod 5 by the drive source 17 such as an electric motor and pushing up the push-up arm 4. It is possible to rotate and rise to the state of. Such back floor board 2a
When the tip end portion of the support arm 6 is turned downward in the clockwise direction in the figure due to the rotation rise of the waist arm support frame 7, one side of the waist support frame 7 is pulled by the tip end portion of the support arm 6 and the other side of the waist support frame 7 is a floating link 8. Is driven to move toward the head of the bed frame 1 and tilt. On the other hand, the rotation of the back floor plate 2a raises the operation link 13
Pushes the waist floorboard 2b along the guide frame 9 of the waist support frame 7 and gradually moves away from the back floorboard 2a, and the middle portion 14 thereof gradually bends the ends of the back floorboard 2a and the waist floorboard 2b on the bent side. Approach. In this way, as shown in FIG. 2 (a), when the back floor plate 2a is rotated and raised to a predetermined angle, the intermediate portion 14 of the operating link 13 and the mattress bridge 15 supported by this intermediate portion 14 are attached to the back portion. The floor plate 2a and the waist floor plate 2b are in close proximity to the bent side ends and fill the gaps between them. Therefore, even if the waist floor plate 2b is gradually separated from the back floor plate 2a in association with the upward movement of the back floor plate 2a and the distance between the ends of the waist floor plate 2b becomes wide, the mattress placed on the floor plate
16 can be prevented from falling due to the weight of the user. Of course, the fall of the mattress 16 can be prevented by fixing the mattress 16 at an appropriate place on the floor plate.

に戻すことができる。In the state of FIG. 2 (a), when the telescopic rod 5 is shortened, the lumber floor plate 2b gradually moves downward as the back floor plate 2a gradually rotates in a planar manner by the reverse operation described above.
Can be returned to the plane state shown in FIG. 2 (c).
（発明の効果） 本発明は以上の通り、背部床板と腰部床板との屈曲部の
間隔を背上げに際して次第に広くなるようにしたので、
使用者の腹部に圧迫感を与えないという効果がある。(Effect of the invention) As described above, the present invention is configured such that the interval between the bent portions of the back floor plate and the waist floor plate is gradually widened when raising the back.
This has the effect of not giving a feeling of pressure to the abdomen of the user.
