Description

[Detailed description of the invention] The present invention is capable of reducing the force required for raising and lowering the floorboard in a bed with a raised floorboard, and also allows the required force to be adjusted appropriately according to the weight of the patient, etc. The present invention relates to a support mechanism for a floor plate in a bed with an undulating floor plate.

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. The back floor plate 1, the lumbar floor plate 2, and the leg floor plate 3 are connected in a flexible manner and are supported on a floor plate support frame 4. .

The back floor plate 1 is rotatably supported on the floor plate support frame 4 with a position 6 suitably distant from the connecting position 5 to the lumbar floor plate 2 toward the head as a rotation fulcrum, and the lumbar floor plate 1 The floor plate support frame 4 is rotated using an appropriate position on the foot side as a pivot point.
Support on top.

In the embodiment shown in FIG. 1, the position 6 of the back floor plate 1 is rotatably supported by a fixed support arm 7 protruding from the floor plate support frame 4, and the leg floor plate 3 is supported at the position 6 of the floor plate support frame 4. The lumbar floor plate 2 is supported by support links 8 and 8' to enhance the four-bar link mechanism, and the lumbar floor plate 2 uses the connection position 9 with the leg floor plate 3 as a pivot point.

In the embodiment shown in FIG. 3, the connection position 9 with the leg floor plate 3 is
A fixed support arm 11 protruding from the floor plate support frame 4 supports a position 10 of the lumbar floor plate 2 close to the lumbar floor plate 2 in a rotatable manner, and a suitable position of the leg floor plate 3 is supported by a rotary support arm 12. The position 6 is rotatably supported by a rotary support arm 13 rotatably fixed to the floor plate support frame 4 at a position closer to the feet than the position 6.

In this way, the position 6 of the back floor plate 1, that is, the pivot point, may be a fixed position or may be movable.
These specific configurations are also appropriate.

Further, the support mechanism for the lumbar floor plate 2 and the leg floor plate 3 can also be configured so that the lumbar floor plate 2 is rotatable about an appropriate position on the foot side as a pivot point.
Any suitable structure may be used depending on the support mechanism of the back floor plate 1.

However, in the present invention, in the above configuration, the lumbar floor plate 2,
This device is characterized in that the weight 14 is fixed so that its fixing position can be freely adjusted in the direction of the head and the foot.

The fixing position adjustment mechanism of the weight 14 shown in the figure is such that the weight 14 provided with a stopper knob 16 is movably fitted into a guide rail 15 attached to the lower side of the lumbar floor plate 2, and the fixing position is continuously adjusted. However, other configurations may also be used in which adjustment can be made only at appropriate intervals.

In this configuration, the back floor plate 1 is tilted by rotating clockwise in the figure with the position 6 as a pivot point, and the lumbar floor plate 2 is rotated using an appropriate position on the foot side as a pivot point to tilt the back floor plate. The first side is tilted downward, thus placing the patient in a raised position.

In this way, in the present invention, the back floor plate 1 has a rotational fulcrum at a position 6 appropriately away from the connection position 5 with the lumbar floor plate 2 toward the head side, and the lumbar floor plate 2 can freely tilt with the foot side as a rotation fulcrum. Therefore, the weight of the patient's lower back is equal to the weight of the back floor plate 1.
Acts in the direction of rotation and upward movement.

Moreover, since the present invention has a weight 14 fixed to the lumbar floor plate 2, the weight of the weight 1') 14 also acts in the direction of rotating and raising the back floor plate 1.

Therefore, the present invention can extremely reduce the force required to raise and lower the back floor plate 1 and the lumbar floor plate 2, as described above.

In such a case, the present invention moves and fixes the weight 14 toward the foot side or the head side, so that the lumbar floor plate 2 is fixed by the weight 14.
The moment in the direction of inclination can be made smaller or larger, so that the required force can be adjusted accordingly.

In addition to being able to adjust the required force for the same patient as appropriate, the present invention can also adjust the required force to be constant regardless of the body weight when used by multiple patients with different body weights. Adjustments can be made.

As mentioned above, the present invention allows the required force for raising and lowering the back floor plate 1 and the waist floor plate 2 to be extremely small, so it goes without saying that a driving device with a small driving force can be used for such raising and lowering, as well as weight balance. , the patient, etc. can raise and lower the floorboard as described above simply by shifting the weight from the head side to the waist side, and omit the drive device and use an appropriate stopper mechanism (not shown in the figure). ing.

) can constitute a rolling bed with just the floorboards.

As described above, the present invention allows the required force for raising and lowering the floorboard to be extremely small, so not only is it sufficient to use a drive device with a small driving force, but it is also possible to omit this and use only the stopper mechanism to move the floorboard. In addition to being able to configure a floating bed and providing such a bed at an extremely low cost,
A major feature is that the required force can be adjusted extremely easily by changing the fixing position of the weight. For example, when the driving device is omitted and the user's own weight, such as a patient, is used to raise and lower the weight. This has the advantage that the required force can always be adjusted appropriately depending on the weight of the user such as a patient, the degree to which he or she can move his or her body, etc.
