In addition, the use experience of the reclining bed can be improved.

In addition, the curved portion provided between the back support and the shoulder support may be located between the second thoracic vertebra and the seventh thoracic vertebra of the lying thoracic column. According to this configuration, the upper body platform is bent near the back bend portion of the back of the layer, and can support the natural backward bend shape of the back while lifting the upper body, so the layer can be lifted in a relaxed posture.

Alternatively, the curved portion provided between the back support and the shoulder support may also be located between the 8th thoracic vertebrae and the 12th thoracic vertebrae of the thoracic column of the lying person. According to this configuration, the upper body platform can bend and lift the upper body while bending the portion that is easier to bend (the part from the dovetail to the lower side) in the upper body of the layer, so that the lye can be lifted in a relaxed posture.

Further, the bed may be provided with a mechanism or an actuator for raising and lowering the shoulder platform relative to the back platform. By using an actuator and a mechanical link mechanism, the degree of freedom in controlling the bending angle of the shoulder platform relative to the back platform is greater.

In addition, the bed may include a telescopic mechanism that changes the distance between the back support and the shoulder support in response to at least one of the back support and the shoulder support. According to this configuration, it is possible to suppress the positional deviation between the upper body platform and the mattress placed thereon when the upper body platform is bent. In addition, since the distance between the back support and the shoulder support can be adjusted and the upper body's curved shape (curvature) can be adjusted, the burden on the body can be reduced.

In addition, the bed may be provided with a standing release mechanism that responds to the release instruction when at least one of the back and shoulder stands is in the standing state, so that both the back and shoulder stands can be raised simultaneously. The state immediately moves to the horizontal state. According to this configuration, for example, in an emergency situation where the physical condition of a lying person changes drastically, the reclining bed can be instantly changed from a standing state to a horizontal state, so that the lying person can be made horizontal and it is easy to perform emergency treatment.

In addition, the bed may be provided with a control device that controls the movement of the shoulder support and the back support. The control device has a control mode that defines the relative relationship between the operating point of the shoulder platform and the operating point of the back platform; and responds to the request for the lifting of the upper body, and makes the shoulder platform and the back platform according to the control mode. Means of lifting by one or both sides.

According to this configuration, it is possible to perform an appropriate upper body lifting with a small burden on the body of the lying person in accordance with the control mode.

In addition, the control device may further include: when one or both of the shoulder platform and the back platform are being raised and lowered, the current operating point of the shoulder platform and the back platform reaches the first position in the control mode. In the case of an operating point, the means for stopping the lifting of the shoulder platform and the back platform is stopped.

According to this configuration, by selecting the first movement point as a point that is ideal for a lying person (for example, the easiest posture), the lifting movement of the upper body will become a more ideal posture for the lying person. Stop at the moment.

In addition, the control device may include a means for notifying the user of the fact that the current operating point of the shoulder support and the back support reaches the first operating point in the control mode when the operating point reaches the first operating point.

According to this configuration, by selecting the first action point, for example, At the point of the ideal posture (such as the easiest posture), the lying person will know that the ideal posture has been reached during the lifting movement of the upper body, and the lifting movement can be stopped there.

The control device may further include means for controlling the raising and lowering of the thigh support when at least one of the shoulder support and the back support is raised and lowered. According to this structure, since the lifting of the thigh support can be linked with the lifting of the shoulder support and the back support, support for the lower body can be added when the upper body is lifted, so that the posture of the lying person can be improved. Comfortable.

In addition, the control device may have a means for grasping the bending degree of each of the first part and the second part of the body of the lying person according to the current operating points of the back, shoulder, and thigh bases. ; And when at least one of the back, shoulder, and thigh stands is raised, the degree of bending of each of the first portion and the second portion does not exceed the respective upper limit value Means of at least one of the operating points of the cap and the shoulder and the thigh.

According to this configuration, it is possible to carefully control the degree of bending of the body of the lying person, and to appropriately limit the body load of the lying person.

In addition, the control device may further include: in response to a command to increase or decrease a speed of at least one of the back support, the shoulder support, and the thigh support, and the back support, the shoulder support, and the thigh support. Means of increasing or decreasing the speed of at least one of the platforms. With this configuration, it is possible to respond to the speed requirements of the lying person.

In addition, the control device may have a means for moving all the back support, shoulder support and thigh support immediately from the current operating point to a horizontal state in response to an instruction for lifting. According to this configuration, in an emergency situation such as a sudden change in the physical condition of the lying person, the bed can be immediately leveled and emergency treatment can be easily performed.

In addition, a reclining bed is formed by supporting the upper body of a lying person so that the upper body platform can be raised and lowered, and the upper body platform may be provided with three or more parts which are respectively carried in different positions in the height direction of the upper body. 3 or more upper body parts capable of being bent to each other; at least one of the mutually bent parts of the upper body parts of more than 3 is arranged to correspond to at least one position between the second thoracic spine and the 12th thoracic spine of the upper body s position. According to this configuration, since there are many bent portions in the upper body load-bearing portion, the upper body platform can be finely bent to a shape that fits the body of the lying person.

[Lifting mechanism]

Next, an example of an elevating mechanism for raising and lowering the back rest 9 and the shoulder rest 10 in the reclining bed 54 of the second embodiment will be described.

In addition, an example of the lifting mechanism described below is applicable not only to the second embodiment but also to the reclining bed 1 of the first embodiment described above.

8 to 11 are diagrams illustrating an example of a lifting mechanism of the back base 9 and the shoulder base 10.

As shown in FIG. 8, a link mechanism 100 (elevating mechanism) is provided on the side of the back table 9 and the shoulder table 10 of the reclining bed 54.

The link mechanism 100 includes a first connection member 101, a rotation bracket 102, and a second connection member 103.

One end side of the first connection member 101 is rotatably connected to the back base 9 through another link mechanism, and the other end side is rotatably connected to the rotation bracket 102.

The rotation bracket 102 is provided so as to be rotatable about a rotation shaft 102a, and one end side of the second connection member 103 is rotatably connected to the rotation bracket 102.

The other end of the second connection member 103 is rotatably connected to the shoulder base 10 through a mounting member.

Accordingly, as the back support 9 is raised by the actuator, the first connection member 101 is pulled in the direction of the arrow A1. In this way, the rotation bracket 102 is rotated around the rotation axis 102a in the direction of arrow A2, and by the rotation of the rotation bracket 102, the second connecting member 103 is pressed in the direction of arrow A3.

The shoulder base 10 is pushed upward by the second connecting member 103 and rotates clockwise around a rotation shaft 104 provided between the back bases 9. As a result, the shoulder base 10 rises as the back base 9 rises.

On the other hand, as shown in FIG. 10, after the angle of the back support 9 with respect to the hip support 4 (base 2) exceeds a predetermined angle (the angle θ 2 described later), the moving direction of the second connection member 103 is reversed. (Arrow A4), the shoulder base 10 starts to descend in a direction opposite to the upward direction. Next, after the angle of the back base 9 becomes the upper limit angle θ x, the angle Φ of the shoulder base 10 with respect to the back base 9 becomes 0 (zero) (see FIG. 11).

Here, as an example, the predetermined angle θ 2 of the back base 9 with respect to the hip base 4 is 50 degrees, and the upper limit angle θ x of the back base 9 is 70 degrees.

In the foregoing embodiment, although the case where the link mechanism 100 provided between the back support 9 and the shoulder support 10 was connected to the back support 9 to raise the shoulder support 10 was exemplified, It is not limited to this.

For example, as shown in FIGS. 12 to 13, an actuator 110 may be provided instead of the link mechanism 100 between the back support 9 and the shoulder support 10.

12 and 13 are diagrams illustrating the raising mechanism of the back support 9 and the shoulder support 10 according to another modification.

As shown in FIG. 12, one end of the actuator 110 is fixed to the back support 9 through a mounting member, and the other end is fixed to the shoulder support 10 through a mounting member.

Therefore, as shown in FIG. 13, after the actuator 110 extends in the direction of the arrow B1, the shoulder platform 10 pressed upward by one end of the actuator 110, that is, rotates around the rotation axis 104 and rises. In this way, since the lifting of the shoulder platform 10 can be controlled by the actuator 110, it can not only be connected with the back The movement of the base 9 can be raised and lowered in conjunction with the movement of the base 9 and can also be lifted and lowered in unison with the movement of the back of the base 9.

Next, a link mechanism 200 (elevating mechanism) that links the movement of the thigh base 26 with the movement of the shoulder base 10 will be described.

14 and 15 are diagrams illustrating a link mechanism 200 that links the movement of the thigh base 26 with the movement of the shoulder base 10.

As shown in FIG. 14, the link mechanism 200 (elevating mechanism) includes a third connection member 201, a rotating arm 202, and a roller 203.

One end of the third connection member 201 is connected to the shoulder base 10 through the mounting member, and the other end is connected to one end side of the rotation arm 202.

A rotation roller 203 is rotatably provided on the other end side of the rotation arm 202.

As shown in FIG. 15, as described in the aforementioned modification example, an actuator 110 is provided between the back support 9 and the shoulder support 10, whereby the shoulder support 10 is raised by the actuator 110. In this way, when the third connecting member 201 is pulled in the direction of the arrow C1, the rotation arm 202 rotates counterclockwise (around the arrow C2) about the rotation axis 202a. As a result, the thigh base 26 is pushed upward by the roller 203 and raised.

As described above, since the reclining bed 54 is provided with the link mechanism 200, the thigh platform 26 can be raised in conjunction with the rising of the shoulder platform 10, and the shoulder support can be reliably performed with a simple link mechanism The linkage between the platform 10 and the thigh support platform 26.

Next, a link mechanism 300 (elevating mechanism) that links the operation of the shoulder base 10 to the operation of the thigh base 26 will be described.

16 and 17 are diagrams illustrating a link mechanism 300 that links the operation of the shoulder base 10 with the operation of the thigh base 26.

As shown in FIG. 16, the link mechanism 300 includes a rotation bracket 301, a rotation roller 302, a fourth connection member 303, and an actuator 120.

The rotation bracket 301 is provided to be able to rotate counterclockwise around the rotation shaft 301a, and a roller 302 is rotatably provided on one end side of the rotation bracket 301.

One end side of a fourth connection member 303 is connected to the other end side of the rotation bracket 301, and the other end side of the fourth connection member 303 is connected to the shoulder base 10 through a mounting member.

One end of the actuator 120 is fixed to the base 2, and the other end of the actuator 120 is connected to the rotation bracket 301 so as to be telescopic.

Thereby, as shown in FIG. 17, the actuator 120 is extended in the direction of the arrow D1, and the rotary bracket 301 is rotated counterclockwise (around the arrow D2) of the rotary shaft 301a, and then the roller 302 on the rotary bracket 301 Press the thigh support 26 upward.

Next, the fourth connecting member 303 connected to the rotary bracket 301 moves in the direction of the arrow D3 and presses the shoulder base 10 upward.

Therefore, with the link mechanism 300, the shoulder platform 10 can be linked with the rise of the thigh platform 26 and then rise, and the shoulder platform 10 and the thigh platform 26 are linked to lie down. Lying can rise and fall in a more relaxed position.

Next, the telescopic mechanism 400 which expands and contracts between the back base 9 and the shoulder base 10 is demonstrated. 18 to 20 are diagrams illustrating the telescopic mechanism 400.

As shown in FIG. 18, the telescopic mechanism 400 includes a connecting member 410, a pin 420, and a pin 421.

The connecting member 410 and the pair of mounting plates 411 and 412 are connected to each other so as to be relatively rotatable with respective rotating portions 411a and 412a.

Mounting holes 411b and 412b are provided in each of the mounting plates 411 and 412, and pins 420 and 421 are inserted into the mounting holes 411b and 412b.

The mounting plate 411 is combined with the back base 9 in a state where the pin 420 is inserted into the pin hole 9a of the back base 9 and connected to the back base 9, and the mounting plate 412 is combined with the shoulder base 10. The pin 421 is inserted into the long hole 10 a of the shoulder base 10 and is connected to the shoulder base 10.

The long hole 10a into which the pin 421 is inserted is formed to be long in the length direction (the height direction of the lying person), so that the pin 421 can move in the length direction of the long hole 10a.

Therefore, as shown in FIG. 19, after the back support 9 is raised by an actuator (not shown) or the like, the fifth connection member 404 is pulled in the direction of the arrow E1 and is connected to the fifth connection member 404. The rotation bracket 405 on one end side rotates around the arrow E2.

As a result, the sixth connecting member 406 connected to the other end side of the rotary bracket 405 is pressed upward in the direction of the arrow E3. In this way, by the sixth connecting member 406, the shoulder base 10 rises, and the position of the pin 421 inserted into the long hole 10a of the shoulder base 10 moves within the long hole 10a, and the shoulder base 10 is relative to the back base. The stage 9 moves to a position separated in the longitudinal direction (see FIG. 20). In the example shown in FIGS. 18 to 20, the distance between the shoulder base 10 and the back base 9 is increased from L3 to L4.

In this way, since the distance between the back bearing 9 and the shoulder bearing 10 is changed in conjunction with the raising (lowering) of the back bearing 9 or the shoulder bearing 10, the back bearing 9 and the shoulder bearing 10 can be changed. The optimal positional relationship is appropriately matched to the change of posture of the upper body (especially the range from the 2nd thoracic vertebra to the 12th thoracic vertebra) during the period when the lying person changes from a horizontal state to a standing state (or from a standing state to a horizontal state). .

In addition, the aforementioned telescopic mechanism 400 is not only provided between the back support 9 and the shoulder support 10. There may also be one or a plurality of other platforms between the thigh support platform 26 and the calf support platform 27.

By providing such a telescopic mechanism 400 between the bases, the length of the base 3 can be simply changed without changing the base 2. Therefore, it is not necessary to prepare a plurality of reclining beds 1 in accordance with the height of the lying person, which can save space in the installation place and reduce installation / equipment costs.

Next, a telescopic mechanism 500 that expands and contracts between the back support 9 and the shoulder support 10 will be described. 21 and 22 are diagrams illustrating the telescopic mechanism 500.

As shown in FIG. 21, the telescopic mechanism 500 includes a first connection member 501 and a second connection member 502.

One end 501a of the first connection member 501 is rotatably connected to the back support 9, and the other end 501b is rotatably connected to one end of the shoulder support 10.

In addition, one end 502a side of the second connecting member 502 is also rotatably connected to the back base 9, and the other end 502b side is also rotatably connected to one end side of the shoulder base 10.

Here, the first connection member 501 and the second connection member 502 are provided in parallel with each other, and the first connection member 501 is set to a length longer than the second connection member 502.

Therefore, as shown in FIG. 22, the shoulder base 10 is raised by an actuator (such as the aforementioned actuator 110) or a link mechanism (such as the aforementioned link mechanism 200), etc. 10 rises, and the first connection member 501 and the second connection member 502 rotate.

In the embodiment, since the first connection member 501 and the second connection member 502 rotate counterclockwise, the shoulder support 10 is separated from the back support 9 by a predetermined distance, that is, between the first connection member 501 and the second connection member 502. The amount of length.

Compared with the back support 9 and the shoulder support 10 when the shoulder support 10 is not raised The distance is L5 (refer to FIG. 21). When the shoulder support 10 has been raised, the distance between the back support 9 and the shoulder support 10 is a distance L6 greater than the distance L5 (refer to FIG. 22).

As described above, the length between the load-bearing sections can be adjusted by a simple mechanism using two connecting members having different lengths.

[Control method of reclining bed]

Next, an example of a control method of the reclining bed according to the second embodiment will be described.

In addition, the control method of the reclining bed in the second embodiment can also be applied to the control method of the reclining bed in the first embodiment.

FIG. 23 is a diagram illustrating a positional relationship between a reclining bed and a body part of a user (lying person) lying on the reclining bed. Fig. 24 is a schematic diagram illustrating the definition of the angles of the respective bases of the reclining bed.

As shown in FIG. 23, when the lye 900 is lying on the reclining bed 54, the rotation axis 22 (curved portion) between the back support 9 and the shoulder support 10 is located on the spine's spine In the manner of the second thoracic vertebra to the seventh thoracic vertebra (the area indicated by the diagonal line 910 in the figure), the length and position of the back support 9 and the shoulder support 10 in the reclining bed are set.

Here, in the case where the lye 900 lies on the reclining bed 54, the length and position of the back support 9 and the shoulder support 10 in the reclining bed are set so that the back support 9 and the shoulders The rotation axis 22 (curved portion) between the 10 pedestals is located between the 8th thoracic vertebra and the 12th thoracic vertebra of the spine of the lying person (area 920 in the figure), which is also very suitable.

As shown in FIG. 24, in the reclining bed 54 of the second embodiment, the hip base 4 is provided in parallel with the base 2 and the base 2 is provided in parallel with the horizontal plane. So, The hip platform 4 is parallel to the horizontal plane.

In this second embodiment, the angle of the back support 9 with respect to the hip support 4 (horizontal plane) is θ, the angle of the shoulder support 10 with respect to the back support 9 is Φ, and the thigh The angle of the base 26 with respect to the hip base 4 (horizontal plane) is set to η. The angle of the shoulder base 10 with respect to the hip base 4 is α (α = θ + Φ: also referred to as forward tilt prevention angle).

In addition, the reclining bed 54 is provided with an actuator for driving each of the bases (the back base 9, the shoulder base 10, the thigh base 26, or the calf base 27). A clutch mechanism (not shown) that switches transmission / non-transmission of the driving force of the actuator.

In addition, the operating parts of these clutch mechanisms are connected to a common line (not shown), and by operating this common line, all clutch mechanisms provided at each stand can be set to be non-transmitting at the same time. The clutch mechanism can be applied to various known clutches.

[Back up (down) motion control]

First, the back raising (lowering) operation control of the reclining bed 54 by a lie-on (user) will be described. The back raising control of this reclining bed 54 is performed by raising the shoulder base 10 and the back base 9 with respect to the hip base 4 by a predetermined angle, respectively.

Fig. 25 is a flowchart illustrating an example of the back-up operation control of the reclining bed 54.

FIG. 26 is a diagram illustrating an example of the chronological movement of the back support 9, the shoulder support 10, and the thigh support 26. The above figure shows the angle Φ of the shoulder support 10 relative to the back support 9. Over time, the middle picture shows the time-dependent action of the angle θ of the back support 9 relative to the hip support 4, and the following picture shows the time-dependent action of the angle η of the thigh support 26 relative to the hip support 4.

Figure 27 shows the angle θ of the back support 9 and the angle Φ of the shoulder support 10 Diagram of relationship over time.

As shown in FIG. 25, in step S101, the operating device (not shown) presses the back-up button of the operating device (not shown) to lie down, and outputs a back to the control device 52 (see FIG. 6). Lift instruction.

In step S102, the control device 52 acquires the current angle θ (action point) of the back support 9 and the current angle Φ (action point) of the shoulder support 10 by using the back-up command as a trigger.

In step S103, the control device 52 determines whether the current angle θ (action point) of the back support 9 and the current angle Φ (action point) of the shoulder support 10 are located above a predetermined control mode stored in the control device 52.

Here, a control mode of each stand stored in the control device 52 will be described.

The control device 52 has a control mode for each of the back support 9, the shoulder support 10, and the thigh support 26 (see FIG. 3). The control device 52 is triggered by the back-up command of the lying person, and controls the actions of the back support 9, the shoulder support 10, and the thigh support 26 according to this control mode.

As shown in the upper diagram of FIG. 26, in the control mode of the angle Φ of the shoulder platform 10, the angle Φ increases with the passage of time, and becomes the upper limit angle Φ x when it reaches a predetermined time T1, and maintains a certain angle Φ x until the predetermined time T2.

The angle Φ decreases with the passage of time after the predetermined time T2, and becomes the minimum angle 0 (zero) when it becomes the time Tx.

In the embodiment, the upper limit angle Φ x is 20 degrees, and the shoulder base 10 is bent with respect to the back base 9 in a range of 0 to 20 degrees.

As shown in the figure in FIG. 26, in the control mode of the angle θ of the back rest 9, the angle θ is 0 (zero) until the time Ta until the angle of the shoulder rest 10 becomes Φ 1 (for example, 5 degrees). However, it is maintained constant, and it gradually increases with time after the time Ta (the time when the angle Φ becomes Φ 1) is exceeded. Next, the back support 9 stops at the time when the upper limit angle θ x is reached.

In the embodiment, the upper limit angle Φ x is 70 degrees, and the back support 9 is bent with respect to the base 2 (horizontal plane) in a range of 0 to 70 degrees.

As shown in the lower diagram of FIG. 26, in the control mode of the angle η of the thigh base 26, the angle η gradually increases with time. Next, the angle η becomes the upper limit angle η 1 at a predetermined time T3, and thereafter decreases with time. Next, the angle η becomes the angle 0 (zero) when the maximum time Tx is reached, and the thigh base 20 stops.

In this embodiment, the upper limit angle η x is 25 degrees, and the thigh base 26 is bent from 0 to 25 degrees with respect to the base 2 (horizontal plane).

Therefore, as shown in FIG. 27, if the relationship between the angle θ of the back support 9 and the angle Φ of the shoulder support 10 is observed, when the angle θ of the back support 9 is 0 (zero), the shoulder support The angle Φ of 10 gradually increases to Φ 1. Then, as the angle θ of the back support 9 increases, the angle Φ of the shoulder support 10 also gradually increases.

While the angle θ of the back support 9 is from θ 1 (for example, 30 degrees) to θ 2 (for example, 50 degrees), the angle Φ of the shoulder support 10 is constant at the upper limit angle Φ x (for example, 20 degrees). After the angle θ of the back bearing 9 exceeds θ 2, the angle Φ of the shoulder bearing 10 gradually decreases, and when the angle θ becomes the upper limit angle θ x (for example, 70 degrees), the angle Φ of the shoulder bearing becomes 0 ( zero).

Next, returning to FIG. 25, in the foregoing step S103, the control device 52 determines that the obtained angle θ of the back base 9 and the angle Φ of the shoulder base 10 are control modes located in the relationship between the display angle θ and the angle Φ Refer to Figure 27).

When the control device 52 determines that the obtained angle θ and angle Φ are in the control mode shown in FIG. 27 (step S103, Yes), in step S104, the control device 52 increases the angle θ according to the control mode (Move it to the right in FIG. 26), and move the back rest 9 and the shoulder rest 10.

In step S105, the control device 52 determines that the angle θ of the back support 9 that has been actuated in step S104 has reached θ 2 (for example, 50 degrees), and the angle Φ of the shoulder support has reached the upper limit angle Φ x (for example, In the case of 20 degrees), the movement of the back support 9 and the shoulder support 10 is stopped.

The control device 52 notifies the lying person that the angle θ of the back support 9 has reached θ 2 and the angle Φ of the shoulder support 10 has reached the upper limit angle Φ x, and releases the back-up command and returns to step S101.

The angle θ 2 (for example, 50 degrees) of the back support 9 and the upper limit angle Φ x (for example, 20 degrees) of the shoulder support 10 are also referred to as the first operating point. As the back support of the reclining bed 54 is made, The platform 9 and the shoulder platform 10 are moved to this first operating point, so that they can take the most relaxed standing posture for a general lying person.

In step S106, the control device 52 stops the back when it is determined that the angle θ of the back support 9 has reached the upper limit angle θ x (for example, 70 degrees) and the angle Φ of the shoulder support 10 has reached 0 (zero). Action of the base 9 and the shoulder 10.

The control device 52, because the angle θ of the back platform 9 has reached the upper limit angle θ x, and the angle Φ of the shoulder platform 10 has reached 0 (zero), therefore, the lying person is notified of the end of the actions of each platform, and is released. The back-up instruction returns to step S101.

Here, in step S103, the control device 52 determines the back obtained When the angle θ of the base 9 and the angle Φ of the shoulder base 10 are not in the control mode shown in FIG. 27 (step S103, No), in step S107, the control device 52 causes the back base 9 and the shoulder The base 10 moves (changes the angle θ and the angle Φ), and moves the angle θ (the operating point) and the angle Φ (the operating point) to the control mode.

Thereafter, the process proceeds to step S104, and the control device 52 increases the angle θ (moves it to the right in FIG. 27), and causes the back support 9 and the shoulder support 10 to operate in a control mode.

Next, when the back of the reclining bed is lowered, the operating device (not shown) outputs a back lowering command to the control device 52 in accordance with the back lowering operation of the lying person (step S101).

The control device 52 obtains the angle θ and the angle Φ using the back-down command as a trigger (step S102), and determines whether the angle θ and the angle Φ are located in the control mode shown in FIG. 27 (step S103).

Next, the control device 52 reduces the angle θ (moves it to the left direction in FIG. 27) in accordance with the control mode, and operates the back support 9 and the shoulder support 10 (step S104).

In step S105, the control device 52 determines that the angle θ of the back support 9 has reached θ 2 (for example, 50 degrees) and the angle Φ of the shoulder support 10 has reached the upper limit angle Φ x (for example, 20 degrees). Stop the movement of the back support 9 and the shoulder support 10. Next, the control device 52 notifies the lying person that the angle θ of the back support 9 has reached θ 2 and the angle Φ of the shoulder support 10 has reached the upper limit angle Φ x, and cancels the back-down instruction and returns to step S101.

In addition, when the control device 52 stops the operations of the back support 9 and the shoulder support 10 in step S105, the lying person or the like continues to press the back up button of the operation device (not shown) for a certain period of time. The stop was lifted and the back-up operation was started again.

Alternatively, after the control device 52 stops the actions of the back support 9 and the shoulder support 10 in step S105, when the lieer or the like presses the back-up button of the operation device (not shown) again, the stop is released. And then started back up again.

In step S106, the control device 52 stops when it is determined that the angle θ of the back support 9 has reached the upper limit angle θ x (for example, 70 degrees) and the angle Φ of the shoulder support 10 has reached 0 (zero). Movement of the back support 9 and the shoulder support 10. Next, the control device 52, because the angle θ of the back support 9 has reached the upper limit angle θ x, and the angle Φ of the shoulder support 10 has reached 0 (zero), it will notify the lying person of the end of each support operation. Then, the back-up instruction is cancelled and the process returns to step S101.

Here, in step S103, the control device 52 determines that the obtained angle θ of the back support 9 and the angle Φ of the shoulder support 10 are not in the control mode shown in FIG. 27 (step S103, No ), In step S107, the control device 52 moves the back support 9 and the shoulder support 10 (changes the angle θ and the angle Φ), and moves the angle θ (the operating point) and the angle Φ (the operating point) to the control mode. .

Thereafter, the process proceeds to step S104, and the control device 52 decreases the angle θ (moves it to the left direction in FIG. 27), and causes the back support 9 and the shoulder support 10 to operate in a control mode.

〔Control of thigh caps〕

Next, a description will be given of a case in which a lieer (user) raises (lowers) the thigh base 26 of the reclining bed 54 with respect to the hip base 4 by a predetermined angle.

FIG. 28 is a flowchart illustrating an example of the operation control of the thigh base 26 of the reclining bed 54.

In step S201, the operating device (not shown) lifts the operation according to the back of the lying person. A back-up command is output to the control device 52.

In step S202, the control device 52 acquires the current angle η (action point) of the thigh base 26 by using the back-up command as a trigger.

In step S203, the control device 52 determines whether the return flag is ON.

The so-called return flag here is a flag that is set (ON) when the angle η of the thigh support 26 exceeds the upper limit angle η x (for example, 25 degrees) as shown in the lower diagram of FIG. 26. That is, it means that in the lower graph of FIG. 26, no reentry flag (return flag OFF) is set to the left of the upper limit angle η x, and a reentry flag (return flag ON) is set to the right.

When the control device 52 sets the turn-back flag (ON), the angle η of the thigh base 26 gradually increases, and it is determined that the upper limit angle η x (for example, 25 degrees) has been exceeded. Next, the control device 52 determines that the return flag (OFF) is not set, that is, it determines that the angle η of the thigh base 26 does not exceed the upper limit angle η x.

When it is determined that the return flag (ON) is set (step S203, YES), the control device 52 proceeds to step S204, and the control device 52 determines whether the angle η is 0 (zero).

When the control device 52 determines that the angle η of the thigh base 26 is 0 (zero) (step S204, Yes), in step S205, the control device 52 stops the operation of the thigh base 26 and returns to step S201.

When the control device 52 determines that the angle η of the thigh base 26 is not 0 (zero) (step S204, No), in step S206, the control device 52 causes the thigh to decrease the angle η The base 26 operates and returns to step S201.

Here, in step S203, the control device 52 determines that the return flag is not ON (that is, OFF) (step S203, No), and in step S207, the control device 52 is It is determined whether the angle η of the thigh base 26 is an upper limit angle η x (for example, 25 degrees).

When the control device 52 determines that the angle η is the upper limit angle η x (step S207, Yes), the control device 52 stops the operation of the thigh base 26 (step S208), and proceeds to step S209.

In step S209, the control device 52 sets a return flag (ON), and returns to step S201.

On the other hand, in step 207, when the control device 52 determines that the angle η is not the upper limit angle η x (step S207, No), that is, after the thigh base 26 is operated to increase the angle η ( Step S210), and the process returns to Step S201.

Next, when the thigh support 26 is lowered in accordance with the back-down instruction (step S201) of the layer (user), the control device 52 obtains the thigh support 26 with the back-down instruction as a trigger. After the angle η (operation point) (step S202), it is determined whether the return flag is OFF (step S203).

When it is determined that the return flag (OFF) is not set (step S203, YES), the control device 52 determines whether the angle η is 0 (zero) (step S204).

When the control device 52 determines that the angle η of the thigh base 26 is 0 (zero) (step S204, Yes), it stops the motion of the thigh base 26 (step S205), and returns to step S201. .

When the control device 52 determines that the angle η of the thigh support 26 is not 0 (zero) (step S204, No), the control device 52 moves the thigh support 26 so as to reduce the angle η (step S204). S206), and the process returns to step S201.

Here, in step S203, the control device 52 determines the angle of the thigh base 26 when it is determined that the return flag is not OFF (that is, ON) (step S203, No). Whether η is the upper limit angle η x (step S207).

When the control device 52 determines that the angle η is the upper limit angle η x (step S207, Yes), the control device 52 stops the operation of the thigh base 26 (step S208), and proceeds to step S209.

In step S209, the control device 52 cancels the setting of the return flag (OFF), and returns to step S201.

On the other hand, in step 207, when the control device 52 determines that the angle η is not the upper limit angle η x (step S207, No), that is, after the thigh base 26 is operated so as to increase the angle η (Step S210) Return to step S201.

Next, another example of the back raising operation control of the reclining bed 54 will be described.

In the foregoing control, although the case where the back support 9 and the shoulder support 10 are linked and moved is described as an example, the back support 9 and the shoulder support 10 and the thigh support 26 may be linked. Come to action.

FIG. 29 is a flowchart of the back-up operation control of another example.

FIG. 30 is a diagram illustrating another example of the chronological movement of the back base 9, the shoulder base 10, and the thigh base 26. The above figure shows the angle Φ of the shoulder base 10 relative to the back base 9. Over time, the middle picture shows the time-dependent movement of the angle θ of the shoulder platform 10 relative to the hip platform 4, and the following picture shows the time-dependent movement of the angle η of the thigh platform 26 relative to the hip platform 4. .

FIG. 31 is a diagram showing the time-dependent relationship between the angle θ of the back base 9 and the angle Φ of the shoulder base 10 and the angle η of the thigh base 26. The above figure shows the angle θ of the back base 9 and the shoulder The relationship between the angle Φ of the base 10 and the following figure shows the relationship between the angle θ of the back support 9 and the angle η of the thigh support 26, and the right shows the angle Φ of the shoulder support 10 and the thigh. The relationship of the angle η of the cap 26.

As shown in FIG. 29, in step S301, the operation device (not shown) outputs a back-up instruction to the control device 52 based on the back-up operation of the layer (user).

In step S302, the control device 52 obtains the current angle θ (action point) of the back support 9 and the current angle Φ (action point) of the shoulder support 10 and the thigh support 26 by triggering the back raising command as a trigger. The current angle η (action point).

In step S303, the control device 52 determines whether the obtained angle θ of the back base 9 and the angle Φ of the shoulder base 10 are in a control mode (refer to the upper diagram of FIG. 31) of the relationship between the display angle θ and the angle Φ. Position, and determine whether the obtained angle θ of the back base 9 and the angle η of the thigh base 26 are located in a position or position of a control mode (refer to the lower diagram of FIG. 31) showing the relationship between the angle θ and the angle η. Whether the obtained angle Φ of the shoulder base 10 and the angle η of the thigh base 26 are located in which position of the control mode (refer to the right diagram of FIG. 31) showing the relationship between the angle Φ and the angle η.

Here, the other control modes of the back-up operation control are the same as the above-mentioned control modes except for the control mode of the angle η of the thigh base 26, so they mainly describe different parts.

As shown in the lower diagram of FIG. 30, in the control mode of the angle η of the thigh base 26, the angle η increases with the passage of time, and becomes the upper limit angle η x (for example, 25 degrees) at a predetermined time T1. , Maintain the upper limit angle η x until the predetermined time T2.

The angle η decreases with the passage of time after the predetermined time T2, and becomes 0 (zero) when the time Tx is reached.

Therefore, as shown in the right diagram of FIG. 31, in a control mode showing the relationship between the angle Φ of the shoulder base 10 and the angle η of the thigh base 26, the angle is proportional to the increase of the angle Φ η also increased.

Returning to FIG. 29, when the control device 52 determines that the obtained angle θ of the back support 9 and the angle Φ of the shoulder support 10 and the angle η of the thigh support 26 are located in the respective control modes ( (Step S303, Yes). In step S304, the control device 52 increases the angle θ according to the control mode (moves it to the right in FIG. 31), and causes the back support 9 and the shoulder support 10 and the thigh. The base 26 moves.

In step S305, the control device 52 determines that the angle θ of the back support 9 that has been actuated in step S304 has reached θ 2 (for example, 50 degrees), and the angle Φ of the shoulder support 10 has reached the upper limit angle Φ x ( When the angle η of the thigh base 26 has reached the upper limit angle η x (for example, 25 degrees), the actions of the back base 9 and the shoulder base 10 and the thigh base 26 are stopped. .

Next, the control device 52 notifies that the angle θ of the back support 9 has reached θ 2, the angle Φ of the shoulder support 10 has reached the upper limit angle Φ x, and the angle η of the thigh support 26 has reached the upper limit angle η x. The person lying down releases the back-up instruction and returns to step S301.

The angle θ 2 (for example, 50 degrees) of the back support 9, the upper limit angle Φ x (for example, 20 degrees) of the shoulder support 10, and the angle η x (for example, 25 degrees) of the thigh support 26 are also referred to as As the first operating point, as the back platform 9, the shoulder platform 10, and the thigh platform 26 of the reclining bed 54 are moved to this first operating point, it is possible to make it the easiest for ordinary lying persons. Standing pose.

In step S306, the control device 52 determines that the angle θ of the back support 9 has reached the upper limit angle θx, the angle Φ of the shoulder support 10 has reached 0 (zero), and the angle η of the thigh support 26 has reached In the case of 0 (zero), the operations of the back support 9, the shoulder support 10 and the thigh support 26 are stopped.

Next, the control device 52, because the angle θ of the back base 9 has reached the upper limit angle θ x, the angle Φ of the shoulder base 10 has reached 0 (zero), and the angle η of the thigh base 26 has reached 0 (zero ), The lying person is notified of the end of the operation, and the back-up instruction is cancelled, and the process returns to step S301.

Here, in step S303, the control device 52 determines that the obtained angle θ of the back support 9 and the angle Φ of the shoulder support 10 and the angle η of the thigh support 26 are different from those shown in FIG. 31. In the case of the control mode (step S303, No), in step S307, the control device 52 causes the back support 9, the shoulder support 10, and the thigh support 26 to move (change the angles θ, Φ, η, respectively). And move the respective angles θ, Φ, η (action points) to the control mode shown in FIG. 31.

Thereafter, the process proceeds to step S304, and the control device 52 increases the angle θ according to the control mode (moves it to the right in FIG. 31), and causes the back support 9, the shoulder support 10, and the thigh support 26 to operate. .

Secondly, when the back of the reclining bed is lowered by the control method of another example, the operation device (not shown) outputs a back-down instruction to the control device 52 based on the back-down operation of the lying person (step S301).

The control device 52 acquires the angles θ, Φ, and η using the back-down command as a trigger (step S302), and determines whether the angles θ, Φ, and η are located in the control mode shown in FIG. 31 (step S303).

Next, when the control device 52 determines that each of the angles θ, Φ, and η is in the control mode (step S303, Yes), the control device 52 reduces the angle θ according to the control mode (moves it to the left in FIG. 7). Direction), and the back support 9 and the shoulder support 10 and the thigh support Operation 26 (step S304).

In step S305, the control device 52 determines that the angle θ of the back support 9 has reached θ 2 (for example, 50 degrees), and the angle Φ of the shoulder support 10 has reached the upper limit angle Φ x (for example, 20 degrees). When the angle η of the base plate 26 has reached the upper limit angle η x (for example, 25 degrees), the operations of the back plate 9 and the shoulder plate 10 and the thigh plate 26 are stopped. Next, the control device 52 controls that the angle θ of the back support 9 has reached θ 2, the angle Φ of the shoulder support 10 has reached the upper limit angle Φ x, and the angle η of the thigh support 26 has reached the upper limit angle η x The lying person is notified, and the back-down instruction is released, and the process returns to step S301.

In addition, the control device 52 stops the operations of the back support 9, the shoulder support 10, and the thigh support 26 in step S305, and then continues to press the back of the operating device (not shown) to lie down to raise the back When the button is pressed for a certain period of time, the stop is released and the back-up operation is started again.

Alternatively, the control device 52 stops the operations of the back support 9, the shoulder support 10, and the thigh support 26 in step S305, and then presses the back of the operating device (not shown) again when the person lies down or the like. When the button is lifted, the stop is released and the back-up action is started again.

In step S306, the control device 52 determines that the angle θ of the back support 9 has reached the upper limit angle θx, the angle Φ of the shoulder support 10 has reached 0 (zero), and the angle η of the thigh support 26 has When it reaches 0 (zero), the operations of the back support 9, the shoulder support 10 and the thigh support 26 are stopped. Next, the control device 52, because the angle θ of the back base 9 has reached the upper limit angle θ x, the angle Φ of the shoulder base 10 has reached 0 (zero), and the angle η of the thigh base 26 has reached 0 (zero ), The lying person is notified of the end of each platform operation, and the back-up instruction is cancelled, and the process returns to step S301.

Here, in step S303, the control device 52 determines the When the angle θ of the platform 9, the angle Φ of the shoulder platform 10, and the angle η of the thigh platform 26 are not in the control mode shown in FIG. 31 (step S303, No), the control device 52 is to move the back support 9, the shoulder support 10, and the thigh support 26 (change each of the angles θ, Φ, and η), and change the angles θ, Φ, and η to move to the control mode.

After that, the process proceeds to step S304, and the control device 52 decreases the angle θ (moves it to the left direction in FIG. 31), and causes the back support 9, the shoulder support 10, and the thigh support 26 to operate in a control mode.

[Forward Lean Prevention Control]

Next, a description will be given of the control for preventing the lying person (user) from leaning forward.

Previously, the tilt prevention control was controlled so that the back support 9 and the shoulder support 10 did not exceed a predetermined angle, and the tilt was increased to prevent the lying person from falling forward (toe-toe direction).

Fig. 32 is a flowchart of the forward tilt prevention control.

In step S401, the operating device is an operation to increase either the angle θ of the back support 9 or the angle Φ of the shoulder support 10 according to the lieer (user), and output the angle θ or angle Φ to the control device 52. Increase instructions.

In step S402, the control device 52 determines whether the previous tilt prevention control is effective. The reclining bed 54 can be set to be effective / ineffective by the operation of a lying person (user) or a caregiver.

Therefore, the control device 52 judges that it is effective when the forward tilt control is set to be effective by the layer or the like (step S402, Yes), and determines that it is invalid when the forward tilt control is set to be invalid. Invalid (step S402, No).

The control device 52 obtains the angle θ of the back base 9 and the angle Φ of the shoulder base 10 when it is determined that the forward tilt prevention control is effective (step S402, YES), and calculates based on the obtained angle θ, Φ Forward prevention angle α (α = θ + Φ) (step S403).

In step S404, the control device 52 determines whether the forward prevention angle α is a limit angle α x (for example, 90 degrees).

The control device 52, when it is determined that the forward tilt prevention angle α is less than the limit angle αx (for example, 90 degrees) is not full (step S404, Yes), the control device 52 controls the back of the lying person to increase the back After either the angle θ of the base 9 or the angle Φ of the shoulder base 10 increases (step S405), the process returns to step S401.

On the other hand, when the control device 52 determines that the forward tilt prevention angle α is equal to or greater than the limit angle α x (for example, 90 degrees) (step S404, No), the control device 52 increases the angle of the back support 9 Either θ or the angle Φ of the shoulder stand 10 is increased and the other is decreased, and the forward tilt prevention angle α is maintained at the limit angle α x (step S406), and the process returns to step S401.

This can realize the expectation of the ascending operation of the back supporter (or shoulder supporter) of the layer, and prevent the laybacker from tilting forward caused by the tilting of the back supporter 9 or the shoulder supporter 10. .

Here, in step S402, the control device 52, when it is determined that the previous tilt prevention control is not effective (invalid) (step S402, No), the control device 52 is performing the back support 9 or the shoulder support. After the stage 10 is controlled to increase either the angle θ of the back stage 9 or the angle Φ of the shoulder stage 10 (step S407), the process returns to step S401.

In addition, in the foregoing step S404, when the forward tilt prevention angle α is larger than the limit angle α x (step S404, No), in step S406, although the angle θ or the angle Φ is further adjusted, The control of increasing one side and decreasing the other side can be controlled so that even if an increase command of angle θ or angle Φ is received (step S401), the angle with the increase command is not increased.

In addition, the maximum tilt angles θ x and Φ x of the movable (standing) range of the back base 9 and the shoulder base 10 may be mechanically limited in such a manner that the forward tilt prevention angle α does not exceed the limit angle α x.

Therefore, when the angle θ of the back bearing 9 or the angle Φ of the shoulder bearing 10 is increased, the situation where the previous tilt prevention angle α exceeds the limit angle α x is calculated based on the angles θ and Φ. The commanded angle θ or angle Φ is increased, and other angles Φ or angle θ are decreased to prevent forward leaning and prevent the angle α from exceeding the limit angle α x.

Therefore, it is possible to satisfy the lying person (or caregiver) because the back support 9 or shoulder support 10 with instructions from the lying person (or caregiver) can be raised while avoiding the lying person to lean forward. ) Operating requirements.

[Body Load Limit Control]

Next, the control of the body load of the lying person (user) will be described.

Lying (user), when lying on the reclining bed 54, when the back or shoulder is bent at a larger angle than the thigh, it becomes sandwiched between the thigh platform 26 and The shape between the back support 9 and the shoulder support 10 makes the body feel a large load.

Therefore, the reclining bed 54 is controlled such that the back or shoulders are positioned relative to the thighs when the lieer (user) raises the thigh support 26, the back support 9 and the shoulder support 10. Do not bend to a larger angle than intended, restricting (preventing) the lying person from being sandwiched by these platforms and making the body feel a greater load.

FIG. 33 is a diagram illustrating the definition of the angle γ and the angle β of the reclining bed 54 with respect to the lying person. Fig. 34 is a flowchart of the body load limit control.

As shown in FIG. 33, in the reclining bed 54, the rotation axis 41 (curved portion) connecting the thigh base 26 and the thigh base 27 of the knees of the lying lie with the touch lying The angle formed by the line segment K1 of the back platform 9 on the back of the lower abdomen and the rotation axis 14 (curved portion) of the hip platform 4 and the shoulder platform 10 is set to γ (also called the first waist bending angle γ) The angle formed by the line segment K1 touching the back of the upper abdomen (dovetail) and the back support 9 is β (also referred to as the second waist bending angle β).

The first waist bending angle γ is a value showing the degree of bending (ie, the degree of bending) near the lower abdomen of a lying person, and the second waist bending angle β is a value showing the degree of bending from the upper abdomen to the chest (that is, the degree of bending) The value of the degree of bending) indicates the degree of the physical burden on the lying person. By controlling the first waist bending angle γ and the second waist bending angle β to not exceed the predetermined upper limit angle, the lying person can be prevented from becoming a thigh base 26, a back base 9 and a shoulder base. 10 the shape of the clamping, causing unnecessary burden on the body.

Hereinafter, a specific control method will be described.

As shown in FIG. 34, in step S501, the operating device (not shown) makes the angle θ of the back support 9, the angle Φ of the shoulder support 10, or the thigh support according to the lying person (user). The operation of increasing any one of the angle η of 26 is to output an increase command of the angle θ, the angle Φ, or the angle η to the control device 52.

In step S502, the control device 52 determines whether or not this body load limit control is effective. The reclining bed can be used to set the effectiveness / ineffectiveness of the body load limit control by the operation of the layer (user) or caregiver.

Therefore, the control device 52 determines that it is effective when the body load limit control is set to be effective by the lying person or the like (step S502, Yes), and determines that it is effective when the body load limit control is set to be invalid. It is invalid (step S502, No).

When it is determined that the body load limit control is set to be effective (step S502, Yes), in step S503, the control device 52 is based on the present angle θ of the back base 9 and the present angle Φ of the shoulder base 10, which is large. The current angle η of the leg base 26 calculates the first waist bending angle γ and the second waist bending angle β.

In step S504, the control device 52 determines whether the second waist bending angle β is equal to or larger than a predetermined upper limit angle β n.

When it is determined that the second waist bending angle β is greater than or equal to the predetermined upper limit angle β n (step S504, Yes), the control device 52 further determines whether the first waist bending angle γ is greater than or equal to the predetermined upper limit angle γ n in step S505.

When it is determined that the first waist bending angle γ is equal to or more than the predetermined upper limit angle γ n (step S505, Yes), the control device 52 controls the back support 9, the shoulder support 10, or the thigh in step S506. After the base 26 moves to increase any one of the angle θ, angle Φ, or angle η from the lying person, the process returns to step S501.

On the other hand, in step S505, when it is determined that the first waist bending angle γ is equal to or greater than the predetermined upper limit angle γ n (step S505, No), the control device 52 has an angle θ, Either the angle Φ or the angle η is increased, and any other angle θ, angle Φ, or the angle η without the increase instruction from the lying person (or both) is decreased (step S507), so that the first After the waist bending angle γ is equal to or more than the predetermined upper limit angle γ n, the back support 9, the shoulder support 10, or the thigh support 26 is operated, and then the process returns to step S501.

Here, in step S504, when it is determined that the second waist bending angle β is less than the predetermined upper limit angle βn (step S504, No), the control device 52 further determines the first waist bending angle γ in step S508. Whether it is equal to or larger than a predetermined upper limit angle γ n.

In step S508, when the first waist bending angle γ is determined to be equal to or greater than the predetermined upper limit angle γ n (step S508, YES), the control device 52 causes the angle θ and the angle Φ from the lying command to increase the command. Or any one of the angles η is increased, and any other angle θ, angle Φ, or angle η (or both) without an increase instruction from the lying person is decreased (step S509), so that the second waist is bent After the angle β becomes the predetermined upper limit angle β n or more, the back support 9, the shoulder support 10, or the thigh support 26 is actuated, and then the process returns to step S501.

On the other hand, in step S508, when it is determined that the first waist bending angle γ is less than the predetermined upper limit angle γn (step S508, No), the control device 52 causes the angle to be increased by a lying command. Any one of θ, angle Φ, or angle η is increased, and any other angle θ, angle Φ, or angle η (or both) without any increase instruction from the lying person is decreased (step S510), so that After the second waist bending angle β becomes the predetermined upper limit angle β n or more and the first waist bending angle γ becomes the predetermined upper limit angle γ n or more, the back support 9, the shoulder support 10, or the thigh support 26 is moved. To return to step S501.

Here, when it is determined in step S502 that the body load limit control is set to be invalid (step S502, No), in step S508, the control device 52 controls the angle θ and angle Φ so that there is an increase instruction from the lying person. Or the angle η is increased so that the back support 9, the shoulder support 10 or the thigh support 26 is actuated, and then the process returns to step S501.

Therefore, when any one of the first waist bending angle γ or the second waist bending angle β exceeds the predetermined upper limit angles γ, β, that is, any one of the angles θ, Φ, and Increasing η can decrease the other angles θ, Φ, and η without increasing instructions, so that the first waist bending angle γ or the second waist bending angle β can not exceed the upper limit angles γ, β.

Therefore, the lying person can avoid being placed in a shape sandwiched between the back support 9, the shoulder support 10, and the thigh support portion 26, and exerts a large load on the body of the lying person.

Next, other examples of the body load limit control will be described.

Fig. 35 is a flowchart of a body load limit control in another example.

In the aforementioned body load limit control, any of the angles θ of the back base 9, the angle Φ of the shoulder base 10, or the angle η of the thigh base 26 through the lying person (user) is performed. One of these operations increases the angle θ, angle Φ, or angle η required from the lying person, and reduces the other angles θ, angle Φ, or angle η that are not required. On the other hand, in the body load limitation control of this other example, it is possible to restrict the application of a large load to the body of the lying person by controlling only the angle Φ of the shoulder support 10.

As shown in FIG. 35, in step S601, the operating device (not shown) outputs an instruction to increase the angle Φ to the control device 52 based on the operation of increasing the angle Φ of the shoulder support 10 through the lie-down person.

In step S602, the control device 52 determines whether the body load limit control of this other example is effective.

When it is determined that the body load limit control of another example is set to be effective (step S602, Yes), the control device 52 acquires the present angle Φ of the shoulder base 9 in step S603.

In step S604, the control device 52 determines whether the angle Φ of the shoulder support 9 is equal to or less than the upper limit angle Φ x (for example, 20 degrees), and when the angle Φ is equal to or less than the upper limit angle Φ x (step Step S604: YES), the shoulder base 10 is operated so that the angle Φ is increased (step S605).

In step S604, the control device 52, when it is determined that the angle Φ is equal to or greater than the upper limit angle Φ x (step S604, No), invalidates the instruction to increase the start angle Φ through the lying person, and controls the angle Φ to not exceed The upper limit angle Φ (step S606).

On the other hand, when it is determined in step S602 that the other body load limit control is set to be invalid (step S602, No), in step S607, the control device 52 increases the angle Φ of the lying person by A command is made to move the shoulder base 10 so as to increase the angle Φ.

Thereby, by controlling the angle Φ of the shoulder bearing portion 10, the shoulder platform 10 is prevented from being excessively bent, and a large load on the body of the lying person can be avoided.

In addition, in the foregoing, although the shoulder bearing portion 10 is prevented from being excessively bent by controlling the angle Φ of the shoulder bearing portion 10, the movable range of the shoulder bearing platform 10 can be mechanically limited to the shoulder bearing portion 10 The maximum value of the movable range does not exceed the upper limit angle Φ x.

〔Adjustment control of platform moving speed〕

Next, the control for adjusting the moving speed of each stage will be described.

Fig. 36 is a flowchart of the control of the moving speed of the platform.

As shown in FIG. 36, in step S701, the control device 52 determines whether each stage (for example, the back stage 9, the shoulder stage 10, or the thigh stage 26) is in the middle of moving, and is not in the middle of moving In this case (step S701, No), the process of step S701 is repeated.

In step S701, the control device 52 determines that each stage (for example, the back stage 9, the shoulder stage 10, or the thigh stage 26) is in the middle of moving (step S701, Yes), In step S701, the control device 52 outputs an instruction to increase (or decrease) the speed of the moving platform to the driving mechanisms 48 to 50 (refer to FIG. 6: actuators) that move the platform.

Next, in step S703, the drive mechanisms 48 to 50 increase (or decrease) the power supplied to each stage and increase (or decrease) the movement speed of each stage, and then return to step S701.

Thereby, since the moving speed of each stand can be adjusted, the bed can be raised and lowered at a speed at which the lying person (or caregiver) can feel comfortable.

The aforementioned control of the movement speed of the platform by the control device 52 (steps S701 to S703) constitutes the speed adjustment device of the present invention.

[Lifting lift control]

Next, it will be described that at least one or all of the respective platforms (the back platform 9, the shoulder platform 10, the thigh platform 26, or the lower leg platform 27) are simultaneously moved from a raised (standing) state to a horizontal position. State control.

Fig. 37 is a flowchart of lifting release control.

First, in step S801, the control device 52 determines whether a clutch mechanism (not shown) for transmitting the driving force of an actuator (not shown) for raising and lowering each of the stands is connected. When it is determined that the clutch mechanism is connected, (Step S801, Yes), the process proceeds to Step S802, and when it is determined that the contract is not concluded (Step S801, No), the process ends.

In step S802, the control device 52 determines whether a caregiver or the like has pressed the release button (not shown). When the release button is pressed (step S802, YES), the process proceeds to step S803, where it is determined that the button When the release button is pushed down (step S802, No), the process ends.

In step S803, the control device 52 determines whether the pressing of the release button is an erroneous operation. When it is determined that the release button is not an erroneous operation (step S803, Yes), it proceeds to step S804, and when it is determined that it is an erroneous operation (step S803). , No), processing ends.

In step S804, the control device 52 separates the clutch mechanism of each stand and proceeds to step S805.

In step S805, the control device 52 determines whether a predetermined time has elapsed. When it is determined that the predetermined time has elapsed (step S805, Yes), it returns to step S801, and when it is determined that the predetermined time has not elapsed (step S805, no ), That is, the process of step S805 is repeated until a predetermined time elapses.

Thereby, the lying-up person can be brought to a horizontal state instantly in an emergency, and it is easier to treat the lying-down person.

In addition, in the aforementioned embodiment, although the curved portions of the back base 9 and the shoulder base 10 are exemplified, the back base 9 and the shoulder base 10 are rotated around the rotation axis 22 of the predetermined back bending position adjustment mechanism 11. In order to explain the situation, in order to make the pedestal more finely curved to fit the shape of the lying body, various methods can be considered as follows.

As an example of such a bending mechanism (method) of the base, a plurality of rotation shafts 22 of the back bending position adjusting mechanism 11 shown in FIG. 2 may be provided at the same back bending position adjusting mechanism 11. In this case, since the back bending position adjusting mechanism 11 is bent at the positions of the plurality of rotation shafts 22, the shape between the back support 9 and the shoulder support 10 can be adapted to the body of the lying person (especially the thoracic spine of the back). Column) shape. Therefore, the lying person can get up in a more relaxed posture.

Further, another embodiment for making the base plate more finely curved will be described using FIG. 38. form. The base of the reclining bed shown in FIG. 38 is an example in which the upper body base is divided into three movable bases (the upper body part bearing portion) to perform a finer bending motion than the above embodiment.

Of the pedestals shown in FIG. 38, the back pedestal 9 has three or more upper body part carrying parts 9A, 9B, and 9C that can be bent to three parts that are different from each other in the height direction of the upper body of the lying person.

Upper body part load-bearing parts 9A, 9B, 9C are attached to their respective bending parts 9A1, 9B1, 9C1 so as to be able to bend with each other. At least any one of these upper body part load-bearing parts 9A, 9B, 9C, or 9A1, 9B1, 9C1 It is arranged at a position corresponding to at least one of the second thoracic vertebra to the twelfth thoracic vertebra of the upper body of the lying person.

In this way, the shape of the back support 9 can be made to match the shape of the body of the layer (especially the thoracic column of the back). Therefore, the lying person can get up in a more relaxed posture.

In addition, the aforementioned configuration is applicable not only to the back base 9 but also to other bases (for example, the shoulder base 10). In addition, by providing three or more of the respective bases, more detailed bending can be performed.

Alternatively, the platform can also be set as a soft material or a mechanism whose shape can be changed softly, which can better fit the shape of the lying person, and can minimize the burden on the body as much as possible, and make the body comfortable. The most possible way to move the upper body platform.

Fig. 39 shows the base of the reclining bed 1A of this embodiment.

As shown in FIG. 39, the reclining bed 1A includes an upper layer 70 which is in contact with a lying person and a lower layer which supports the weight of the lying person (hereinafter referred to as a supporting layer 71).

The upper layer 70 is a flexible elastic member. The softer material of lying down.

The support layer 71 includes, for example, a first support layer 71A for supporting a calf of a lying person, a second support layer 71B for supporting a thigh, a third support layer 71C for supporting the buttocks, a fourth support layer 71D for supporting the back, and A fifth support layer 71E supporting the shoulder.

A predetermined gap is provided between each of the first support layer 71A to the fifth support layer 71E, and the gap is filled with a soft material having the same flexibility as the upper layer 70, for example. Therefore, the first support layer 71A to the fifth support layer 71E are provided so as to be bendable at their respective gaps.

The first support layer 71A to the fifth support layer 71E can be raised and lowered by an actuator (not shown), and the first support layer 71A to the fifth support layer 71E can be raised and lowered by an actuator. The reclining bed 1A is bent between the first support layer 71A to the fifth support layer 71E, and changes into a shape suitable for the posture of a lying person. Thereby, the bending position of the reclining bed can be changed more softly, and the comfort of the reclining bed can be improved.

In addition, in the foregoing, although the case where the five support layers of the first support layer 71A to the fifth support layer 71E are provided is described as an example, more support layers may be provided to make the bending position of the reclining bed softer.地 变。 Ground change.
