Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support mechanism for a back floor plate in a sectional bed with an up-and-down floor plate.

The floorboard can be attached to the floorboard support frame with a simple assembly operation.
As a mechanism for rotatably raising and lowering the back floor plate rotatably supported by the floor plate support frame, there is a mechanism in which an operating arm for pushing up the back floor plate is rotatably protruded from the floor plate support frame. However, in the conventional mechanism in which the operating arm is not fixed to the back floor plate and only operates upward to push it up,
Since the back floor plate can move independently of the operating arm in the upward direction, there is a risk that the back floor plate will move due to external force and fall down in the opposite direction. There is a particularly high risk of this happening in beds that use the weight on the lumbar floor plate connected to the back floor plate when it rotates upward, and the back floor plate may move up and down unnecessarily due to the shift of weight. It has the disadvantage of being stored away. In order to eliminate this drawback, the actuating arm and the back floor plate are fixed, but there is a drawback that assembly becomes troublesome.

The present invention is aimed at overcoming the above-mentioned drawbacks of the prior art, and is designed to be easy to assemble and to restrict unnecessary movement of the back floor plate. A detailed explanation will be given below based on an example.

Reference numeral 1 denotes a floor plate support frame, and 2 denotes a floor plate supported by the floor plate support frame 1 in an assembled manner. The floorboard 2 in the illustrated example has a back floorboard 3, a lumbar floorboard 4, and a foot floorboard 5 that are connected together in a flexible manner so as to be foldable. A tapered support rod 5 is rotatably protruded, and the support rod 5 is fitted into a fitting frame 6 provided on the floor plate support frame 1 to rotatably support the back floor plate 3. , the lumbar floor plate 4 and the foot floor plate 5 are supported by swing support arms 7 and 7', respectively. In addition, the specific structure of the floorboard 2 is, for example, composed of a back floorboard 3 and another floorboard constructed separately from this, and only the back floorboard 3 is rotatable.
It is appropriate that at least the back floor plate 3 is rotatable, such as the other floor plates being fixed. An actuating arm 8 for pushing up the back floor plate 3 is rotatably protruded from the floor plate support frame 1, and a support roller 9 is provided on the back floor plate 3 at a position where the actuating arm 8 pushes it up. A stop frame 10 through which the operating arm 8 can be freely inserted is rotatably provided. Reference numeral 11 denotes an actuating device configured to be driven by an electric motor 12. A moving portion 13 of the actuating device 11 is connected to an actuating member 14 of the actuating arm 8.
3 rotates the operating arm 8. In addition, the mechanism for rotating the operating arm 8 may be any suitable mechanism such as a mechanism using a gas spring.

In this configuration, the actuating arm 8 is inserted through the stopper frame 10 when the back floor plate 3 is attached to the floor plate support frame 1. In the illustrated example, the length of the actuating arm 8 is such that its tip can be freely engaged and detached from the stopper frame 10 when the back floor plate 3 is raised at a predetermined angle or more. Although the actuating arm 8 is configured to be able to be freely inserted into the stopper frame 10 even after being attached to the support frame 1, it is not necessarily necessary to limit the length of the actuating arm 8 if the actuating arm 8 is inserted through the stop frame 10 before being attached. As described above, the back floor plate 3 is rotatably supported, and the other floor plates 4,
5 is appropriately attached to the floor plate support frame 1 by swinging support arms 7, 7', etc., thereby constructing a floor plate undulating type bed.

In the above configuration, when the actuating arm 8 is rotated upward by the actuating device 11, the actuating arm 8 pushes up the support roller 9, so that the back floor plate 3 can be rotated upward. In the case of the illustrated floor plate configuration, the weight of the patient on the lumbar floor plate 4 acts in the upward direction of the back floor plate 3, so that the required force is light.

Therefore, when the back floor plate 3 is supported in an inclined state by the actuating arm 8, even if an external force acts to tilt the back floor plate 3 forward, that is, toward the feet, the back floor plate 3 will remain in the stopper frame. Since it is supported by the operating arm 8 via the arm 10, it will not fall down. In addition, in the case of the illustrated floor plate configuration, even if a force is applied in the direction of raising the back floor plate 3 due to a patient's weight shift, etc., the back floor plate 3 will not rise, and the back floor plate 3 will not move up and down unnecessarily. .

As described above, in the present invention, the actuating arm for pushing up the back floorboard is inserted through the stopper frame provided on the back floorboard to restrict its movement. It is safe because it does not move, and since the operating arm is not fixed to the back floor plate with screws, bolts, etc., it does not hinder ease of assembly.
