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 above-mentioned position N6 of the back floorboard 1 is rotatably supported by a fixed support arm 7 protruding from the floorboard support frame 4, and the leg floorboard 3 is supported by the floorboard 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, the present invention provides the above-mentioned back floor plate 1 in the above configuration.
A spring 14 for biasing the back floor plate 1 in the direction of inclination is attached between the floor plate support frame 4 and the floor plate support frame 4 so that the mounting interval can be freely adjusted so as to adjust the biasing force.

FIG. 3a shows that the floor plate support frame 4 is provided with a mounting plate 16 in which a plurality of fitting holes 15 are formed in the longitudinal direction, and a spring 14 is provided on the floor plate support frame 4.
A mounting member 17 that can be freely fitted into the fitting hole 15 is provided, and the mounting distance is adjusted by changing the fitting position between the mounting member 17 and the fitting hole 15.

In addition, FIG. 3 shows that the mounting member 18 attached to the spring 14 is rotatably attached to the mounting plate 19 provided on the floor plate support frame 4, and the stopper pin 20 is placed at the position where the mounting member 18 is rotated appropriately. is fitted into one of the plurality of fitting holes 21 provided in the mounting plate 19 and fixed, and by changing the fitting position, the mounting interval of the springs 14 is adjusted.

In addition, in FIG. 3, the reference numeral 22 indicates the stopper pin 20.
This is the knob that operates the.

In addition to the above configuration, any configuration may be used as long as the spring 14 is attached so that the mounting interval can be adjusted to adjust the biasing force.

Further, the spring 14 itself may be a tension coil spring as shown in the figure, or may be a torsion spring or a compression spring.

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 is pivoted at a position 6 that is appropriately located toward the head side from the connection position 5 with the lumbar floor plate 2, and the lumbar floor plate 2 is tilted with the foot side as the pivot point. Since the back floor plate 1 is flexible, the weight of the patient's lower back is
Acts in the direction of rotation and upward movement.

Moreover, in the present invention, a spring 14 is provided between the back floor plate 1 and the floor plate support frame 4, which biases the back floor plate 1 in the direction of inclination, and the biasing force of the spring 14 also causes the back floor plate 1 to rotate upward. It acts on

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 can appropriately adjust the required force by adjusting the mounting interval of the springs 14 and adjusting the biasing force thereof.

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 to raise and lower the back floor plate 1 and the lumbar floor plate 2 to be extremely small. By maintaining 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. are doing.

) 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 adjusting the spacing between the springs. This has the advantage that the required force can always be appropriately adjusted depending on the weight of the user such as a patient, the level of physical strength to move his or her body, etc.
