Description

[Detailed description of the invention] The present invention provides a support mechanism for a floorboard that can reduce the force required for raising and lowering the floorboard in a bed with a raised floorboard, and can adjust the height of the floorboard. It is something to do.

The present invention will be described in detail below based on examples.

Reference numeral 1 denotes a back floor plate, 2 a waist floor plate, and 3 a leg floor plate, which connect the back floor plate 1, waist floor plate 2, and leg floor plate 3 in a flexible manner.

Among these floorboards, the back floorboard 1 is provided with a first rotary support arm 7 which is rotatably fixed to a floorboard support frame 6 at a position 5 located an appropriate distance l away from the connection point 4 with the lumbar floorboard 2 toward the head. In addition to having a supporting structure, the waist floor plate 2 and the leg floor plate 3
is a second pivot support arm 10 connected between the leg floor plate 3 and the floor plate support frame 6 at a position 9 remote from their connection point 8; The leg floor plate 3 or the waist floor plate 2 and the floor plate support frame 6
The structure is such that it is supported by a third rotary support arm 12 connected therebetween.

And the first one above. Second and third rotation support arms 7°10
．． 12 is the back floor plate 1, the waist floor plate 2, and the leg floor plate 3.
It is configured so that the parallel motion mechanism is used when the plane is used.

In the drawings, FIGS. 1 and 2 show the third rotation support arm 1.
2 is connected to the lumbar floor plate 2, and FIG. Of course, this is also a good thing.

Reference numeral A denotes a stopper means for fixing the first rotary support arm 7 at an appropriate angle.

In the figure, the stopper means A is connected to the first rotation support arm 7.
A stopper arm 13 is provided on the stopper arm 13, and a stopper arm 13 is provided on the stopper arm 13.
- A knob 15 for operating the collar pin 14 is provided, and the stopper pin 14 is attached to the floor plate support frame 6 by, for example, a spring 1.
Although the stopper hole 16 is provided with a stopper hole 16 that is inserted by the snap of the button 7, other configurations are free.

As shown in FIGS. 1 and 2a, the first rotation support arm 7 is fixed by the stopper means A at the rotated and raised position, and the back floor plate 1, the lumbar floor plate 2 and the legs are fixed. When the floor plate 3 is supported upwardly, the back floor plate 1 is rotated clockwise in the figure using the position 5 rotatably supported by the tenth rotation support arm 7 as a rotation fulcrum. At the same time, the connecting point 4 rotates clockwise and lowers, so the lumbar floor plate 2 and the leg floor plate 3 move toward the head side while being supported by the second and third rotation support arms 10.12. , the patient, etc. can be placed in a raised position.

In the present invention, the back floor plate 1 has a rotational fulcrum at a position 5 appropriately away from the connection point 4 with the lumbar floor plate 2 toward the head, so that the weight of the patient's lower back is transferred to the back floor plate 1. It acts in the direction of rotation and upward movement, and as described above, the required force for raising and lowering the back floor plate 1 and the waist floor plate 2 is small.

For this reason, the present invention uses a drive device with a small driving force (not shown in the figure).

), and if the above-mentioned position 5 is a position where the weight of the upper body and lumbar region is well balanced, the weight of the patient's head side can be shifted to the lumbar region. It is also possible to raise and lower the floorboard, in which case a suitable stopper device (not shown in the figure) can be used instead of a drive device such as a gas spring.

) can constitute a rolling bed with just the floorboards.

In this way, the present invention requires less force when raising and lowering the floorboard, so a drive device can be omitted or a drive device with a small capacity can be used, which simplifies the structure of the bed with a floorboard that can be raised and lowers the cost. There are benefits to be gained.

Next, the back floor plate 1,
When the lumbar floor plate 2 and the leg floor plate 3 are maintained in a flat state, the first. Since the second and third rotational support arms 7, 10.12 have a parallel movement mechanism, the first rotational support arm 7 can be freely rotated by releasing the fixation by the stopper means A. By doing so, the entire floorboard 1, 2.
3 can be raised and lowered in parallel.

FIG. 2A shows the state lowered from FIG. 2A.

In this way, the present invention allows the height of the entire floorboard 1, 2.3 to be adjusted appropriately.

Incidentally, in the present invention, in the state shown in FIG. After fixing the rotation support arm 7,
The slope of the back floor plate 1 can also be loosened to obtain the state shown in FIG. 2a.

Furthermore, in the figure, the above-mentioned No. 1. Although the second and third rotation support arms 7, 10.12 are inclined toward the head side, the reverse may be possible depending on the case.

In the former case, that is, in the illustrated embodiment, when the back floor plate 1 is tilted as described above, the connection point 4 between it and the lumbar floor plate 2 is lowered, and at the same time the second and third rotation support arms 10. Since the positions 9 and 11 of the lumbar floor plate 2 and the leg floor plate 3 supported by 12 are lowered, only the lumbar region of the patient, etc. does not slump, and a natural and comfortable posture can be achieved.

As described above, the present invention requires only a small amount of force to raise the back, so not only is it sufficient to use a drive device with a small drive force, but this device can also be omitted and the bed can be configured with a raised floor plate using only the stopper device. It has the characteristic of being able to

In addition, the present invention makes it possible to raise and lower the entire floor board in parallel by rationally using the rotating support arm for raising and lowering the floor board, and adjust the height to a height suitable for examination, treatment, making a bed, or getting on and off a patient. It has the characteristic of being able to

Furthermore, the present invention has a feature that the undulation and elevation of the floorboard are integrated in a very rational manner, so the structure is simple and it can be supplied at low cost.
