がある。(Prior Art and Problems to be Solved by the Invention) In most of the conventional beds in which the back floor is configured to be able to rotate up and down, the pivot point of the back floor remains unchanged.
When you move up the dorsal floor from a supine position, your upper body gradually moves toward your feet. Therefore, for example, a cabinet placed in a position that can be easily used while supine becomes difficult to use;
If a bed lamp is installed on the wall at the head of the bed, the lamp will gradually move away from the light source, which may cause problems such as difficulty in reading.

The back floor elevating mechanism in the bed of the present invention includes a floor support cart 3 that is movable along the longitudinal direction of the floor support frame 2 of the bed 1, and a floor A fixed to the floor support cart 3. The floor support frame 2 is configured to be movable along the longitudinal direction, and at least the back floor 4 of the floor A is configured to be rotatable up and down, and an actuating body 6 is attached to the head rail 5 of the bed 1 by an up/down drive mechanism. A support arm 7 is provided on the operating body 6 so as to be movable up and down, and the tip of the support arm 7 is rotatably fixed to the lower side of the head side of the back floor 4, so that the operation body 6 can be moved up and down. Mechanism B includes a screw shaft 8 rotatably supported in the vertical direction of the head side fence 5, a motor 9 connected to the lower side of the screw shaft 8, and a female screw 10 provided on the operating body 6.

図ａに示すような背上げの状態となる。(Function) In the state shown in FIG. 1b, when the motor 9 is operated to rotate the screw shaft 8, the female screw 10 and the operating body 6 rise. As the operating body 6 rises, the support arm 7 rises, and the part of the back bed 4 to which the tip of the support arm 7 is fixed is raised, and the back bed 4 rotates around the fulcrum 11 and rises. Since the tip of the support arm 7 only moves upward,
As the back floor 4 rotates and rises, the floor support cart 3 is pulled and moved in the cranial direction, that is, to the left in the figure, via its fulcrum 11. In this way, the dorsal floor 4 rotates and rises while moving the other floors in the cephalad direction.
Your back will be in a raised position as shown in Figure a.

の車輪である。(Embodiment) In the embodiment shown in FIG. is fixed to the floor support cart 3. Although the lumbar floor 13 and the foot floor 14 are configured to be able to be raised and lowered as shown by imaginary lines in the figure by means of an undulating mechanism (not shown), they may also be constructed integrally and not raised or lowered. In the embodiment shown in the figure, the fulcrum 1 of the dorsal floor 4
1 is constructed at a position connected to the intermediate floor 12, but the fulcrum 11 can also be directly provided at an appropriate location on the floor support cart 3. In addition, a configuration in which the floor support cart 3 is made freely movable along the longitudinal direction of the floor support frame 2 is, for example, as shown in FIG.
The floor support frame 2 may have a U-shaped configuration in which the wheels 15 are opposed to each other, and the wheels 15 provided on both sides of the floor support cart 3 may be movably installed within the floor support frame 2. FIG. 2 shows an embodiment of a head fence 5 that uses a screw shaft mechanism as the lifting drive mechanism B. This head fence 5 can be attached to and detached from the floor support frame 2 using a well-known mounting member 16. It has a structure that allows it to be attached freely. In addition, the reference numeral 17 is a lid body provided with a slit 18 that allows the support arm 7 to pass through, and 19 is another wheel on the floor.

ある。(Effects of the Invention) As described above, the present invention rotates and raises the dorsal bed while moving other beds in the cephalad direction to raise the back. With this configuration, the user's upper body does not gradually shift toward the feet as the user raises his/her back, and the cabinet etc. can be easily used in either the supine state or the back-raised state. In addition, when a bed lamp is used, there is an effect that reading and the like can be performed satisfactorily in any case. Further, in the present invention, since the back floor is supported by both the rotation fulcrum and the tip of the support arm, reinforcement of the back floor can be made simpler than before, and
Since the elevating and lowering drive mechanism composed of a screw shaft, a motor, and a female screw is provided on the head rail, there is an effect that the space below the floor support frame can be used effectively.
