[0008] <First Embodiment> (Bed) Embodiments of the present invention will be described below with reference to the drawings. In this specification, when a user lies supine on a bed, the direction of the head as seen from the torso is called the "head side", the direction of the feet is called the "foot side", the direction of the right hand is called the "right side", the direction of the left hand is called the "left side", the direction of the floor of the room is called the "down side", and the direction of the ceiling is called the "up side". The right side and the left side are collectively called the "short side", the head side and the foot side are collectively called the "long side", and the up side and the down side are collectively called the "up and down direction".

[0009] Figure 1 is a perspective view of the bed according to this embodiment, seen from diagonally above. Figure 2 is a top view of the bed according to this embodiment, seen from above. As shown in Figure 1, the bed 200 according to this embodiment includes a remote controller 100, an actuator, a lifting mechanism, a bottom 80, a bottom frame, and a base frame.

[0010] The actuator is connected to the remote controller 100 and controls the raising and lowering of the bottom 80. The lifting mechanism is connected to the remote controller 100 and controls the height of the bottom 80. The remote controller 100 controls the raising and lowering of the bottom 80 and the height of the bottom 80. Details of the remote controller 100 will be described later.

[0011] The bottom 80 moves up and down via the bottom frame. Two bottom frames are provided along the longitudinal direction of the bed 200, spaced apart in the short direction. The base frame is located below the bottom frame.

[0012] The bottom 80 includes a back bottom 81, a waist bottom 82, a knee bottom 83, and a foot bottom 84. The back bottom 81 is fixed to a back frame that supports it from below. The back frame is fixed to the bottom frame. The back bottom 81 is positioned at the head end of a person lying on the bed 200. The back bottom 81 also supports the head or back of a person lying on the bed 200. The back frame moves up and down at the head end, with the foot end of the back bottom 81 as the pivot point, by the operation of an actuator. This makes the back bottom 81 foldable relative to the bottom frame.

[0013] The lumbar support base 82 is positioned closer to the feet than the back support base 81. The lumbar support base 82 is fixed to a lumbar frame that supports it from below. The lumbar frame is fixed to the bottom frame. The lumbar support base 82 supports the lumbar region or buttocks of a person lying on the bed 200.

[0014] The knee bottom 83 is positioned further towards the foot than the hip bottom 82. The knee bottom 83 is fixed to a knee frame that supports it from below. The knee frame is fixed to the bottom frame. The knee bottom 83 supports the thigh of a person lying on the bed 200. The knee frame moves up and down at the foot end, with the head end of the knee bottom 83 as the pivot point, due to the operation of an actuator. This allows the knee bottom 83 to be raised and lowered relative to the bottom frame.

[0015] The foot base 84 is positioned further towards the foot than the knee base 83. The foot base 84 is fixed to a foot frame that supports it from below. The foot frame is fixed to the bottom frame. The foot base 84 supports the lower leg of a person lying on the bed 200. The foot frame moves up and down at the head end, with the foot end of the foot base 84 as the pivot point, by the action of an actuator. This allows the foot base 84 to be raised and lowered relative to the bottom frame.

[0016] The lifting mechanism includes an electric cylinder and a lifting frame. The lifting frame is supported by the base frame and connected to the bottom frame. The lifting mechanism drives a lifting motor to raise and lower the bottom frame via the lifting frame. In other words, the lifting mechanism raises and lowers the bottom 80. The lifting mechanism can adjust the height dimension from the floor and the base frame to the bottom 80. The height dimension by the lifting mechanism can be selected from, for example, 10 levels. The lifting mechanism can also tilt the bottom frame by raising the head end of the bottom frame and lowering the foot end of the bottom frame.

[0017] (Remote Controller) Figures 3, 4, and 5 are schematic diagrams of the remote controller according to this embodiment. Figures 3 onwards show a front view of the remote controller. The remote controller 100 according to this embodiment includes a housing 10 and a display panel 20, as shown in Figures 3, 4, and 5. The state of the bottom 80 includes the degree to which the bottom 80 is tilted. The degree to which the bottom 80 is tilted is indicated by a progress bar 40. The progress bar 40 visually displays the current degree to which the bottom 80 is tilted, like a bar graph.

[0018] Figure 3 shows the progress bar 40 when the angle of the back bottom 81 is 30°. The remote controller 100 shown in Figures 4 and 5 shows the progress bar 40 when the angle of the back bottom 81 is 60°. The 60° progress bar 40 shown in Figure 4 has progressed further than the 30° progress bar 40 shown in Figure 3. In this way, the current degree of tilting of the bottom 80 can be visually confirmed. The angles here are the angles of the back bottom 81, knee bottom 83, and foot bottom 84 relative to the non-tilted waist bottom 82.

[0019] Apart from this embodiment, a reference example can be considered in which the degree of tilting of the bottom 80 is not indicated by the progress bar 40. In that reference example, it is not possible to intuitively grasp how far the control operation of the object of interest has progressed and what position it is currently at within the entire range of motion.

[0020] In contrast, in the remote controller 100 according to this embodiment, the degree of tilting of the bottom 80 is indicated by the progress bar 40, making it easy to understand what state the current position of the bed 200 is in within its entire range of motion.

[0021] The remote controller 100 is attached to, for example, an electric bed. This electric bed is used not only as a nursing bed or medical bed, but also as a reclining bed or a gatch-up bed in nursing homes, medical facilities, and the user's home. The users of the bed 200 and the remote controller 100 are, for example, patients or those requiring care. The remote controller 100 and the bed 200 may also have a function to change the patient's position to prevent pressure ulcers and contractures, in which case a configuration in which the operation of the bed 200 is controlled by the remote controller 100 may be adopted. The remote controller 100 is suitable for use by staff who need to operate the bed 200 in a limited amount of time, or by those who frequently raise and lower the bottom 80, such as the back bottom 81.

[0022] The remote controller 100 is attached to, for example, a medical bed. The remote controller 100 according to this embodiment has few operation buttons, making it suitable for easy operation for caregivers, patients other than those receiving intensive care, staff at medical and elderly care facilities, visiting care staff and their families in home care, and for anyone seeking simplicity and ease of use. As a result of its simple operation, it can be operated easily and quickly by touch, and it is easy to understand what position the bed 200 is currently in within its entire range of motion.

[0023] Especially for high-performance medical beds used in intensive care units, etc., operation can be complex, so a dedicated operating interface for medical staff in intensive care units, etc., may be built into the remote controller 100. The display panel 20 may also display an operation switching button that allows switching between a first screen for simple operation and a second screen for operating the high-performance medical bed. This makes it possible to perform both simple and complex operations with a single remote controller 100. In addition, a dedicated operating interface for medical staff operating high-performance medical beds may be equipped separately from the remote controller 100.

[0024] As shown in Figures 3, 4, and 5, the remote controller 100 includes a first button 21 and a second button 22. The first button 21 and the second button 22 are displayed on the display panel 20. The first button 21 and the second button 22 are touch panels within the display panel 20. The first button 21 raises the bottom 80. The second button 22 lowers the bottom 80. When the first button 21 is pressed, either the back bottom 81, the knee bottom 83, or the foot bottom 84 rises. When the second button 22 is pressed, either the back bottom 81, the knee bottom 83, or the foot bottom 84 lowers. Note that the "head" displayed on the display panel 20 in Figures 3, 4, and 5 corresponds to the back bottom 81. As shown in Figures 3, 4, and 5, the display panel 20 may display one or more states of the back bottom 81, the knee bottom 83, or the foot bottom 84.

[0025] The progress bar 40 may extend in a first direction D1. The first direction D1 may be, for example, the Y-axis direction. One direction perpendicular to the Y-axis direction is defined as the X-axis direction. The direction perpendicular to both the X-axis direction and the Y-axis direction is defined as the Z-axis direction. The second direction D2 intersecting the first direction D1 may be, for example, the X-axis direction. The third direction D3 may be the Z-axis direction.

[0026] The progress bar 40 may be displayed using at least a first and second color. In the case of raising and lowering control of the back bottom 81 in Figure 3, when the first button 21 is pressed, the actuator coupled to the back bottom 81 performs an operation to raise the back bottom 81. As a result, the raising angle of the back bottom 81 increases. At this time, the range of the second color displayed on the progress bar 40 increases. On the other hand, when the second button 22 is pressed, the angle of the back bottom 81 decreases. At this time, the range of the first color displayed on the progress bar 40 increases. The change in the angle of the back bottom 81 is detected by an angle sensor attached to the back bottom 81 or by the detection output of the amount of movement of the actuator, and notified to the remote controller 100. This notification may be made by an announcement unit 51, which will be described later. The remote controller 100 changes the size of the area displayed in the first color of the progress bar 40 (height within the progress bar 40) according to the detection result of the back angle.

[0027] For example, when the backrest bottom 81 is horizontal (0°) and the floor surface is flat, the colored portion is not displayed on the progress bar 40. In this case, the second color displayed on the progress bar 40 is not shown, and only the first color is displayed, or a very small portion of the second color is displayed at the bottom of the progress bar 40. Also, when the backrest bottom 81 is at the maximum backrest angle (e.g., 80°), the progress bar 40 is completely covered by the colored portion from the bottom to the top, indicating that it has reached the maximum range of motion. In this case, the first color displayed on the progress bar 40 is not shown, and only the second color is displayed. Furthermore, when the backrest bottom 81 is set to any angle using the first button 21 or the second button 22, the current position of the backrest bottom 81 within the entire range of motion is visually displayed, making it easier to understand its current state.

[0028] In the example above, the back angle of the back bottom 81 was detected and the display of the first and second color areas of the progress bar 40 was changed. However, the display of the progress bar 40 may also be changed based on the operation input of the first button 21 and the second button 22.

[0029] As shown in Figures 3, 4, and 5, the remote controller 100 may include a toggle button 27 that displays at least a first display mode on the display panel 20. The first display mode is a mode for raising and lowering the bottom 80. In the first display mode, the display panel 20 includes a first area R1 and a second area R2. In the first display mode, only the first button 21 and the second button 22 are displayed in the first area R1, and at least the toggle button 27 is displayed in the second area R2. The first button 21 and the second button 22 are adjacent to each other. This makes it easy to raise and lower the bottom 80. Fine adjustment of raising and lowering is possible. Quick operation is possible when raising or lowering the bottom 80.

[0030] The remote controller 100 shown in Figures 3 and 4 is in a state where the bottom 80 has not been raised or lowered. In other words, neither the first button 21 nor the second button 22 is pressed, and arrows corresponding to both the first button 21 and the second button 22 are displayed. The direction of the arrows corresponds to the direction of raising or lowering the bottom 80, and the operation of the bottom 80 is controlled by pressing the first button 21 or the second button 22 corresponding to each arrow.

[0031] The remote controller 100 shown in Figure 5 is in a state where the bottom 80 is being raised or lowered. In other words, the first button 21 is pressed. The arrow corresponds to the direction in which the bottom 80 is raised, and pressing the first button 21 near the upward arrow causes the bottom 80 to rise or become higher.

[0032] In the first region R1, when the first button 21 is pressed, only an upward arrow is displayed on the display panel 20. When the second button 22 is pressed, only a downward arrow is displayed on the display panel 20. In other words, only arrows indicating the direction of raising or lowering the bottom 80 are displayed. At this time, the upward or downward arrows may be displayed larger than the arrows shown in Figures 3 and 4, which represent the unoperated state.

[0033] The areas of the first button 21 and the second button 22 may divide the area of ​​the first region R1 in the first direction D1. The first button 21 and the second button 22 occupy the area of ​​the first region R1. The boundary B1 between the first button 21 and the second button 22 is the midpoint of the first region R1 in the first direction D1. This makes it easier to raise and lower the bottom 80. Fine adjustment of raising and lowering is possible. Faster operation is possible when raising or lowering the bottom 80.

[0034] A model display 29 showing the degree of tilting of the bottom 80 as a pictogram may be displayed in the center of the first region R1. In the model display 29, for example, if the back bottom 81 is at a steep angle, the part of the model display 29 corresponding to the back bottom 81 will be at a steep angle. The angle of the bottom 80 may be displayed on the display panel 20. The degree of tilting of the bottom 80 may be displayed in 10 steps. For example, step 1 may be 13° and step 2 may be 26°.

[0035] The remote controller 100 may include a vibrating unit 50. The vibrating unit 50 vibrates in response to the pressing of the first button 21 and the second button 22, providing the user with a tactile response to the button operation input. The remote controller 100 may also include an announcement unit 51. The announcement unit 51 makes an announcement by voice in response to the pressing of the first button 21 and the second button 22. The vibrating unit 50 and the announcement unit 51 are built into the housing 10.

[0036] The remote controller 100 may include a control unit 52. The control unit 52 turns off the display on the display panel 20 after a certain period of time has elapsed. The control unit 52 is built into the housing 10.

[0037] A call button 28 may be displayed in the second area R2. The call button 28 is a button for calling caregivers, medical staff, family members, etc. When the call button 28 is pressed, communication may be possible with, for example, a nurse call system (intercom for calling nurses), a staff station (staff room), and a family member's smartphone.

[0038] The display panel 20 may be equipped with a display device such as an LCD display panel or an organic EL display panel, and can present any user interface. The display panel 20 may display in color. Furthermore, a touch sensor is superimposed on the display panel 20, allowing the user interface to be operated by touching the surface of the display panel 20. The various buttons provided on the display panel 20 may be pressure-sensitive or capacitive. The remote controller 100 may be sealed inside by the housing 10 and the display panel 20.

[0039] According to this embodiment, it is possible to realize a remote controller and bed that allows for easy confirmation of the current position of the bed and easy raising and lowering operations.

[0040] <First Modified Example of the First Embodiment> Figure 6 is a schematic diagram of a remote controller according to the first modified example of this embodiment. Figure 6 shows the second display mode displayed on the display panel. As shown in Figure 6, the switch button 27 further displays the second display mode on the display panel 20. In the remote controllers of Figures 3 to 5 described above, one progress bar 40 corresponding to one function, and the first button 21 and the second button 22 were displayed in the first area R1, but the second display mode of this modified example includes progress bars 40 of the first progress bar 41 and the second progress bar 42 in the first area R1. The second display mode is a mode in which the raising and lowering of the bottom 80 and the height of the bottom 80 are displayed using the two progress bars 40, and the back angle and height of the bottom 80 are adjusted.

[0041] In the second display mode, the first progress bar 41 on the right side of the first region R1 corresponds to the back angle of the bottom 80, and the first button 21 (increase back angle) and the second button 22 (decrease back angle) are superimposed and arranged; the second progress bar 42 on the left side of the first region R1 corresponds to the height of the bottom 80, and the third button 23 (raise bottom) and the fourth button 24 (lower bottom) are superimposed and arranged.

[0042] The first progress bar 41 on the right side, similar to the display of the progress bar 40 relating to the back-raising angle of the bottom 80 shown in FIGS. 3 to 5, the entire height direction (Y direction) of the bar corresponds to the entire movable range of the tilting operation of the back angle of the bottom 80. The detected value of the current back angle of the bottom 80 is displayed in different colors according to the height (size of the region) of the third region R3. Said color coding may be implemented by a first color and a second color.

[0043] Similarly, the entire height direction (Y direction) of the second progress bar 42 on the left side corresponds to the entire movable range of the lifting operation of the bottom 80, and the detected value of the current height of the bottom 80 is displayed in different colors in the fourth region R4. Said color coding may be implemented by a first color and a second color, or by a third color and a fourth color.

[0044] With such a configuration, the state quantities of a plurality of operation parts (in this modification, two state quantities, namely the back angle of the bottom 80 and the height of the bottom 80) can be simultaneously visually grasped within one screen, and operation is also facilitated.

[0045] It should be noted that the height of the bottom 80 is defined as the distance from the floor surface and the base frame to the waist bottom 82.

[0046] In FIG. 6, the left and right first progress bar 41 and second progress bar 42 are displayed in the first region R1. In the first progress bar 41 (back angle of the bottom 80) on the right side, the third region R3 corresponding to the current value of the back angle is displayed in different colors, and the first button 21 (increase back angle) and the second button 22 (decrease back angle) are displayed in a superimposed manner. The color coding is as described above.

[0047] On the left second progress bar 42 (height of the bottom 80), a fourth region R4 corresponding to the current value of the bottom height is displayed in different colors, and a third button 23 (raise bottom) and a fourth button 24 (lower bottom) are displayed in an overlapping manner. The color coding is as described above.

[0048] The area of the first button 21 and the area of the second button 22 bisect the area of the third region R3 in the first direction D1. The area of the third button 23 and the area of the fourth button 24 bisect the area of the fourth region R4 in the first direction D1. A boundary B2 between the third button 23 and the fourth button 24 is located near the center of the first region R1 and the fourth region R4 in the first direction D1, and may be located at the midpoint thereof. A boundary B1 between the first button 21 and the second button 22 may be located at the same position as the boundary B2 between the third button 23 and the fourth button 24 in the first direction D1.

[0049] In the fourth region R4, a third color and a fourth color indicating the level of the height of the bottom 80 may be displayed. The area of the third color increases when the third button 23 is pressed. The area of the fourth color increases when the fourth button 24 is pressed. The color indicating the tilting level of the bottom 80 is different from the color indicating the height level of the bottom. By distinguishing the color for the tilting level of the bottom 80 from the color for the height level of the bottom 80, the tilting level of the bottom 80 and the height level of the bottom 80 can each be grasped in an easily understandable manner.

[0050] Except for these points, the configuration and effects of the remote controller 101 according to the first modification of the present embodiment are the same as those of the remote controller 100.

[0051] <Second Modification of First Embodiment> FIG. 7 is a schematic diagram of a remote controller according to the second modification of the present embodiment. As shown in FIG. 7, a remote controller 102 according to the second modification of the embodiment includes a housing 10 and a display panel 20. The state includes the level of the height of the bottom 80. The level of the height of the bottom 80 is indicated by a progress bar 40. The progress bar 40 extends in a second direction D2 intersecting the first direction D1.

[0052] The display panel 20 shows a first state button 31, a second state button 32, a third state button 33, and a fourth state button 34 for changing the degree to which the bottom 80 is tilted. The first state button 31 is, for example, a button for changing the bottom 80 to a position that makes it easier to get up. The second state button 32 is, for example, a button for changing the bottom 80 to a position that makes it easier to relax. The third state button 33 is, for example, a button for changing the bottom 80 to a position that makes it easier to eat. The fourth state button 34 is, for example, a button for changing the bottom 80 to a position that helps to reduce leg swelling. The positions corresponding to these first to fourth state buttons 31 to 34 are stored as target value data for each actuator that drives each movable part of the bed in a memory connected to the controller that controls the operation of the bed. When any of the first to fourth state buttons 31 to 34 are pressed, the target data is read from the memory and the controller issues a drive command to each actuator.

[0053] The positions corresponding to the first to fourth state buttons 31 to 34 are not limited to being stored in memory in advance; a position memory function may also be used to record desired positions later through a specific user operation.

[0054] When the first state button 31, second state button 32, third state button 33, and fourth state button 34 are pressed, at least one of the back bottom 81, knee bottom 83, and foot bottom 84 is raised or lowered. The positions for getting up, relaxing, eating, and reducing swelling are frequently used. In this way, even within the limited area of ​​the display panel 20, the operation of changing the state can be made easy by limiting the number of change buttons.

[0055] The display panel 20 displays a progress bar 40 that corresponds to the height adjustment of the bottom 80. In this embodiment, the progress bar 40 is displayed in a configuration that extends horizontally (in the X direction) at the bottom of the display panel 20 and is displayed on the same screen as the first to fourth status buttons 31 to 34.

[0056] The progress bar 40 represents the range of motion of the bottom 80's height across its entire lateral extension, and the detected actual height of the bottom 80 is displayed in color in the fifth region R5. The color coding may be in the first and second colors. When the bottom 80 is at its lowest height, the second color is not displayed in the fifth region R5, or only a very small amount of the second color is displayed at the left end of the progress bar 40. When the bottom 80 is at its highest height, the second color extends from the left end to the right end of the progress bar 40 in the fifth region R5, so that the entire progress bar 40 is colored with the second color in the fifth region R5.

[0057] The progress bar 40 displays the fifth state button 35 (minimum height / fall prevention), the sixth state button 36 (getting out of bed / standing up), and the seventh state button 37 (assistance / diaper change) superimposed. The fifth state button 35 is, for example, a button to change to the minimum height for fall prevention. The sixth state button 36 is, for example, a button to change to the height for getting out of bed and standing up. The seventh state button 37 is, for example, a button to change to the height for assistance such as diaper changes.

[0058] The height of the bottom 80 can be adjusted to any height using the fifth button 25 and the sixth button 26. In this embodiment, if the appropriate bottom height setting is known in advance depending on the patient's movements and the content of care, the bed movements (height of the bottom 80) corresponding to each are set as state buttons on the progress bar 40, and each state button is superimposed on a position within the progress bar corresponding to the bed movement.

[0059] Specifically, in cases where it is desirable to set the bottom 80 to its minimum height to prevent falls, this is assigned to the fifth state button 35 (minimum height / fall prevention) and positioned near the left end of the progress bar 40 (low height of bottom 80). When a bed user presses the fifth state button 35 (minimum height / fall prevention), the bed automatically drives the bottom 80 to the predetermined low-floor state, and the progress bar 40 also displays a bar indicating the low-floor state.

[0060] Furthermore, when a bed user needs to get out of bed or stand up, it is desirable to set the bed to a suitable height (for example, below the center of the bed height range, about 25-35 cm). In such cases, this is assigned to the sixth state button 36 (getting out of bed / standing up) and positioned near the center of the progress bar 40 (at a medium height for the bottom 80). When a bed user presses the sixth state button 36 (getting out of bed / standing up), the bed is automatically moved to the pre-set bottom 80 height (medium) for getting out of bed, and the progress bar 40 display also extends to the central part indicating the bed height for getting out of bed.

[0061] Furthermore, in cases where it is desirable for the height of the bottom 80 to be set higher while the bed user is receiving care from the care staff, this is assigned to the seventh state button 37 (care / diaper change) and positioned near the right end of the progress bar 40 (where the bottom 80 height is high). When the care staff presses the seventh state button 37 (care / diaper change), the bed automatically moves to the pre-set height of the bottom 80 for care (high), and the progress bar 40 display also extends to the right end indicating the floor height for care. In this case, the height of the bottom 80 (high) may be around 60 cm to 65 cm.

[0062] When the seventh state button 37 is pressed, the height of the bottom 80 is higher than when the sixth state button 36 is pressed. When the sixth state button 36 is pressed, the height of the bottom 80 is higher than when the fifth state button 35 is pressed. The display on the progress bar 40 changes according to the height of the bottom 80 when the fifth state button 35, the sixth state button 36, and the seventh state button 37 are pressed, so that the current height of the bottom 80 can be understood.

[0063] In the above example, the 5th to 7th state buttons 35 to 37 are superimposed on the progress bar 40, and a position (height of the bottom 80) is assigned to each. However, this configuration is not limited to this, and it may also be configured to control the desired position by displaying arrows corresponding to the raising and lowering movement of the bottom 80, similar to the embodiments described above (for example, Figures 3 to 5). Alternatively, it may be possible to switch between superimposing the 5th to 7th state buttons 35 to 37 on the progress bar 40 and superimposing arrows for operation control.

[0064] Furthermore, in the above embodiment, the control target of the progress bar 40 was set to the height of the bottom 80, but it is not limited to this, and it may also be used to control the height of the back angle of the bottom 80, or it may be assigned to other drive controls of the bed. When the progress bar 40 is assigned to control the height of the back angle of the bottom 80, the assigned state buttons may be: sleeping (back angle 0°, flat setting), relaxing / watching TV (back angle 40°, medium setting), eating (back angle 80°, maximum raised setting), etc.

[0065] If the progress bar 40 is assigned to control the illuminance of individual lights, the assignable status buttons include: off (illuminance 0, completely off), sleeping (around 3 lux, like a night light), relaxing / watching TV (200 lux, medium setting), eating (500 lux, maximum setting), etc.

[0066] In the remote controller 102, the state of the bottom 80 may further include the degree to which the bottom 80 is tilted. The degree to which the bottom 80 is tilted is indicated by the model display 29.

[0067] The remote controller 102 includes a fifth button 25 and a sixth button 26. The fifth button 25 raises the bottom 80. The sixth button 26 lowers the bottom 80. The fifth button 25 and the sixth button 26 are provided on the housing 10 and outside the display panel 20. The fifth button 25 and the sixth button 26 are not pressure-sensitive or capacitive touch panels. The fifth button 25 and the sixth button 26 are so-called physical buttons. This allows for more precise raising and lowering of the bottom 80.

[0068] The configuration and effects of the remote controller 102 according to the second modified example of this embodiment, excluding those mentioned above, are the same as those of the remote controller 100.

[0069] <Second Embodiment> The configuration of the bed 200 in this embodiment is the same as in the first embodiment. The same applies to the other embodiments and their modifications described below. Figure 8 is a schematic diagram of the remote controller according to the second embodiment. Figures 8 and subsequent figures show a front view of the remote controller.

[0070] The remote controller 110 according to the second embodiment includes a housing 10, a display panel 20, a first button 61, and a second button 62, as shown in Figure 8. The housing 10 includes at least a first region R5. The display panel 20 is provided in the first region R5. The first button 61 and the second button 62 are provided in a part of the housing 10 excluding the first region R5. The first button 61 raises the bottom 80. The second button 62 lowers the bottom 80. The first button 61 and the second button 62 are so-called physical buttons.

[0071] A possible example is one in which the first button 61 and the second button 62 are located on a touch panel provided on the display panel 20. In this example, given the limited size of the display area on the display panel 20, the first button 61, the second button 62, various setting controls, displays, etc., are arranged at a high density, which may be difficult for elderly users. Operation becomes even more difficult for users who have difficulty bending their joints due to conditions such as rheumatism, or for users who have difficulty with fine motor skills due to hand tremors.

[0072] In contrast, in the remote controller 110 according to this embodiment, the first button 61 and the second button 62 are located outside the display area and in a part of the area of ​​the housing 10 excluding the first area R5, making it easy for elderly users to raise and lower the bottom 80. Furthermore, since the first button 61 and the second button 62 are made of physical buttons, a suitable click feeling is obtained, further improving operability.

[0073] The display panel 20 includes a first switch button 64, a second switch button 65, a third switch button 66, and a fourth switch button 67. The first switch button 64 (linked) sets the back bottom 81, knee bottom 83, and foot bottom 84 to a mode that controls the amount of drive of the back bottom 81 and foot bottom 84, in a mode that operates them in a linked manner. The second switch button 65 (head) sets the back bottom 81 to a mode that controls the amount of back elevation by switching the tilting position of the back bottom 81. The third switch button 66 (foot) sets the knee bottom 83 or foot bottom 84 to a mode that adjusts the tilting position of the knee bottom 83 or foot bottom 84. The fourth switch button 67 sets the bottom frame to a mode that adjusts the raising and lowering position of the bottom frame.

[0074] For example, when the first switch button 64 (interlocking) is pressed, the target areas are the settings of the back bottom 81, knee bottom 83, and foot bottom 84, and the control of each part is linked, driving the entire bed, including the waist bottom 82 (which is not subject to tilt control), from a flat state to a knee-raising movement linked to back elevation or a chair position state. The knee-raising movement prevents the user's waist and back from shifting towards the feet during gatch movement and back elevation.

[0075] Furthermore, when the second switch button 65 (head) is pressed, the target area for raising and lowering the bottom 80 becomes the back bottom 81, and the raising and lowering of the back angle is controlled. When the third switch button 66 (feet) is pressed, the raising and lowering of the foot bottom 84 is set as the control target, and the tilt angle of the knee bottom 83 is also controlled. When the fourth switch button (height) 67 is pressed, the lift mechanism of the base frame is set as the control target, and its raising and lowering height is controlled. The height of the bottom 80 is the distance from the floor and base frame to the waist bottom 82.

[0076] In some cases, an electric bed 200 may be connected to an air mattress composed of multiple air cells, which allows for control of its hardness and partial inflation / deflation, as well as a biometric information monitoring device that detects biosignal information such as the bed user's heart rate and respiration, information on whether the bed user is out of bed, and sleep state information that determines the state of sleep. These devices may be controlled by a remote controller 110. Even when there are many functions to switch on the remote controller 110, the number of functions to be switched is limited to a predetermined number (for example, four functions of the bottom of the electric bed 200: linkage, head, foot, and height adjustment), and only the first to fourth switching buttons 64 to 67 are displayed on the display panel 20 as described above. This allows switching between a "simple operation mode" that provides a simplified GUI for users who have difficulty with the detailed operation of the remote controller 110, and a "multifunctional operation mode" that allows caregivers and medical staff who can perform detailed operations to operate not only the various parts of the bottom of the electric bed 200, but also the connected air mattress and peripheral devices such as the biometric information monitoring device, with a predetermined operation on the remote controller 110. In "Multifunction Operation Mode," the number of functions that can be operated using the display panel 20 is greater than in "Simple Operation Mode," but more precise operation is required to select and adjust each function.

[0077] The second toggle button 65 displays the degree of tilting of the back bottom 81 by extending in the first direction D1. The third toggle button 66 displays the degree of tilting of the foot bottom 84 by extending in the first direction D1. The fourth toggle button 67 displays the degree of raising or lowering of the base frame by extending in the first direction D1. For example, the longer the second toggle button 65 extends in the first direction D1, the greater the angle of the back bottom 81's back elevation. For example, the longer the fourth toggle button 67 extends in the first direction D1, the higher the base frame becomes, and the higher the entire bottom surface becomes. This makes it easy to understand the tilting or height state of the bottom 80.

[0078] In the first area R5 of the display area, when any of the first toggle button 64 (linkage), second toggle button 65 (head), third toggle button 66 (foot), or fourth toggle button 67 (height) within the display panel 20 is pressed, the pressed button is highlighted, and the target for adjustment is selected. In this state, the first button 61 (up arrow) and second button 62 (down arrow), which are set outside the display panel 20, receive adjustment input for the selected target. For example, if the second toggle button 65 (head) is selected, the first button 61 (up arrow) and second button 62 (down arrow) are assigned to raise and lower the back angle of the back bottom 81, and the back angle is adjusted according to the user's button operation input. Also, if the third toggle button 66 (foot) is selected, the first button 61 (up arrow) and second button 62 (down arrow) receive operation input for the height of the foot bottom 84. In this case, the angle of the knee bottom 83 is adjusted in conjunction with the height of the foot bottom 84, and is controlled so that no step occurs between the knee bottom 83 and the foot bottom 84. Similarly, when the fourth switching button 67 (height) is selected, the first button 61 (up arrow) and the second button 62 (down arrow) accept input for adjusting the height of the base frame.

[0079] Arrows may be displayed on the first button 61 and the second button 62. The direction of the arrows corresponds to the direction of tilting or raising / lowering of the bottom 80. Pressing the up arrow raises or raises the bottom 80. Pressing the down arrow lowers or lowers the bottom 80.

[0080] The first toggle button 64, the second toggle button 65, the third toggle button 66, and the fourth toggle button 67 may be arranged along the second direction D2 which intersects the first direction D1.

[0081] The first button 61 and the second button 62 may be arranged along the first direction D1.

[0082] The housing 10 may further include a second region R6 and a third region R7. The first button 61 is located in the second region R6. The second button 62 is located in the third region R7. The first region R5 is located between the second region R6 and the third region R7. This makes it easy to determine the positions of the first button 61 and the second button 62.

[0083] The display panel 20 may show the angle of the back bottom 81 and the height of the base frame at the target part, or it may show the angles and heights of each bottom 81 to 84 in more detail. The degree of back angle raising of the back bottom 81 may be displayed in 10 steps. For example, step 1 may be 13° and step 2 may be 26°.

[0084] The selection of the control target assigned to each of the first to fourth switching buttons 64 to 67 is not limited to the above example. The second switching button 65 may be a button to switch the up and down position of the foot bottom 84 or the knee bottom 83. The third switching button 66 may be a button to switch the up and down position of the back bottom 81 or the knee bottom 83.

[0085] Furthermore, the angles and heights of each bottom 81-84 and the height of the base frame may be represented by a pictogram model 29. For example, in the model display 29, if, for example, the back bottom 81 is set to an arbitrary angle, the part of the model display 29 corresponding to the back bottom 81 is displayed at an angle corresponding to the set angle. The model display 29 may be displayed in at least a first color and a second color. For example, when the first switching button 64 is pressed, two or more of the back bottom 81, knee bottom 83, and foot bottom 84 are displayed in the first color, and the parts other than those displayed in the first color are displayed in the second color. Also, for example, when the second switching button 65 is pressed, the back bottom 81 is displayed in the first color, and the knee bottom 83 and foot bottom 84 other than the back bottom 81 are displayed in the second color.

[0086] The remote controller 110 may include a vibration unit 50, an announcement unit 51, and a control unit 52. The vibration unit 50 vibrates in response to pressure from the first button 61 and the second button 62. The announcement unit 51 makes an announcement in response to pressure from the first button 61 and the second button 62. The vibration unit 50, the announcement unit 51, and the control unit 52 are housed in the housing 10.

[0087] For example, in a remote controller for raising and lowering the bed base, touch panel operation can be difficult for elderly users. Furthermore, touch panel operation can be difficult for users with conditions such as rheumatism, who have difficulty bending their joints, or for users with hand tremors who have difficulty with fine motor skills. According to the second embodiment, a remote controller and bed can be provided that allow even users with difficulty operating touch panels to easily raise and lower the bed base.

[0088] <Modification of the Second Embodiment> Figure 9 is a schematic diagram of a remote controller according to a modification of the second embodiment. In the remote controller 111, the housing 10 includes a fourth region R8 provided between the first region R5 and the third region R7, as shown in Figure 9. The fourth region R8 is provided with a trackpad 63 for selecting the first switch button 64, the second switch button 65, the third switch button 66, and the fourth switch button 67. The first button 61 and the second button 62 raise or lower the bottom 80 selected by the trackpad 63. The trackpad 63 is a so-called physical button with a touch sensor that detects its position within the fourth region R8. As a result, the user can easily select the switch button (corresponding control part) to be selected by selecting the position corresponding to the first to fourth switch buttons 64 to 67 in the left-right direction within the fourth region R8.

[0089] Furthermore, in this modified example, as shown in Figure 9, a trackpad 63 is provided in the fourth region R8 between the first region R5 and the third region R7, and selection of the first to fourth switching buttons 64 to 67 is performed using this trackpad. However, the configuration is not limited to this. A physical button with a touch sensor, equipped with a capacitive touch sensor on the surface of a large physical button, which provides both position input via the touch panel and click input by pressing the physical button, can be provided in place of the second button 62, and this physical button with a touch sensor can be placed in a position corresponding to the fourth region R8 near the bottom of the display panel 20. In this case, selection of the first to fourth switching buttons 64 to 67 is performed by operating the touch sensor of the physical button with a touch sensor, and fine adjustment of the selected object is performed by click input by pressing the physical button of the sensor. The configuration and effects of the remote controller 111 in the modified example of the second embodiment, excluding these, are the same as those of the remote controller 110.

[0090] <Third Embodiment> Figure 10 is a schematic diagram of a remote controller according to the third embodiment. In the remote controller 112, the housing 10 includes a second region R6, as shown in Figure 10. The first button 61 and the second button 62 are provided in the second region R6. The first button 61 is adjacent to the second button 62.

[0091] The area of ​​the first button 61 may be the same as the area of ​​the second button 62. The areas of the first button 61 and the second button 62 may divide the area of ​​the second region R6 in the first direction D1. The boundary B3 between the first button 61 and the second button 62 is the midpoint of the second region R6 in the first direction D1. This provides larger adjustment buttons (first button 61 and second button 62) compared to the area of ​​the display panel 20, making it easier and more reliable to operate the controlled object.

[0092] Figure 11 is a schematic diagram of a remote controller according to the third embodiment. In the remote controller 112, the first switch button 64 and the third switch button 66 are arranged in the first direction D1, as shown in Figure 11. The first switch button 64 and the second switch button 65 may be arranged in the second direction D2.

[0093] Figure 12 is a schematic diagram of a remote controller according to the third embodiment. In the remote controller 112, the first switch button 64, the second switch button 65, the third switch button 66, and the fourth switch button 67 may be arranged along a second direction D2 that intersects the first direction D1, as shown in Figure 12.

[0094] The configuration and effects of the remote controller 112 according to the third embodiment, excluding these features, are the same as those of the remote controller 110.

[0095] <Modification of the Third Embodiment> Figure 13 is a schematic diagram of a remote controller according to a modification of the third embodiment. In the remote controller 113, the housing 10 includes a fourth region R8 provided between the first region R5 and the second region R6, as shown in Figure 13. The fourth region R8 is provided with a trackpad 63 for selecting the first switch button 64, the second switch button 65, the third switch button 66, and the fourth switch button 67. The first button 61 and the second button 62 raise or lower the bottom 80 selected by the trackpad 63. The trackpad 63 is as described above. This makes it easy to select the part of the bottom 80 that you want to raise or lower.

[0096] The configuration and effects of the remote controller 113, excluding those described above, are the same as those of the remote controller 110.

[0097] <Fourth Embodiment> Figure 14 is a schematic diagram of the remote controller according to the fourth embodiment. Figure 14 and Figure 18, which will be described later, show a front view of the remote controller. The remote controller 120 according to this embodiment includes a housing 10, a display panel 20, and operation buttons, as shown in Figure 14. The display panel 20 is provided on the housing 10. The operation buttons are provided in the corners of the display panel 20. The operation buttons are buttons for operating the bottom 80.

[0098] Apart from this embodiment, an implementation in which the operation buttons are not located in the corners of the display panel 20, but are instead positioned at any location within the display area of ​​the display panel 20, can be considered as a reference example. In that reference example, since there is no fixed information to rely on for understanding the arrangement of the operation buttons within the display panel 20, it is necessary to visually check the position of the operation buttons within the display panel 20 each time an operation is performed, which reduces operability such as touch typing.

[0099] In contrast, in the remote controller 120 according to this embodiment, the operation buttons are located in the corners of the display panel 20, making it easy to determine the location of the operation buttons within the display panel 20 by touch. This clarifies the arrangement of the operation buttons within the display panel 20. As a result, improved operability, such as touch typing, is possible.

[0100] The remote controller 120 according to this embodiment has few operation buttons and is easy to operate, allowing for quick and intuitive operation. Furthermore, there is little need to repeatedly look at the display screen, making it possible to operate it by touch.

[0101] Because the remote controller 120 of this embodiment is easy to operate, it is suitable for use in nursing care facilities by care recipients who have difficulty with complex and detailed operations. At the same time, it is expected to have the effect of enabling smooth and intuitive operation even when used by care staff or family members of care recipients. Furthermore, in hospitals and other similar settings, it is suitable for use by patients who have difficulty with detailed operations, and it is also expected to have the effect of making operation intuitive and easy for medical staff.

[0102] The operation buttons may be the main buttons for operating the bed 200. The operation buttons may be, for example, body part switching buttons 70. The body part switching buttons 70 switch the parts of the bottom 80 that are raised or lowered. The body part switching buttons 70 include a first switching button 71, a second switching button 72, a third switching button 73, and a fourth switching button 74. The first switching button 71 switches the raising or lowering of the back bottom 81. The second switching button 72 switches the raising or lowering of the foot bottom 84. The third switching button 73 links the back bottom 81, knee bottom 83, and foot bottom 84 to switch the raising or lowering of the back bottom 81 and foot bottom 84. The fourth switching button 74 switches the raising and lowering of the bottom 80. For example, when the first switching button 71 is pressed, the target part of the bottom 80 for raising or lowering is the back bottom 81. When it is desired to raise either the back bottom 81 or the foot bottom 84, or to change the height of the bottom 80, the corresponding button is pressed. In Figure 14 and Figure 18 (described later), the "head" and "feet" displayed on the display panel 20 correspond to the back bottom 81 and foot bottom 84, respectively. The height of the bottom 80 is the distance from the floor and base frame to the waist bottom 82.

[0103] The first toggle button 71, the second toggle button 72, the third toggle button 73, and the fourth toggle button 74 may be provided at the four corners of the display panel 20. This makes it possible to identify the four corners of the display panel 20 by the difference in texture between the housing 10 and the display panel 20, thus making the arrangement of the operation buttons within the display panel 20 clearer. As a result, improved operability, such as touch typing, is possible.

[0104] In the example above, the user pressed one of the first to fourth toggle buttons 71 to 74 located at the four corners of the display panel 20 to select the function to be adjusted, and then selected the tilt button 75 to adjust any part. Function selection is not limited to pressing the first to fourth toggle buttons 71 to 74. Functions to be selected are pre-assigned to each of the four corners of the display panel 20, and icons that identify the assigned function are displayed at each of the four corners of the display panel 20. Then, the user can select the function assigned to the corresponding corner by sliding (swiping) their hand across the surface of the display panel 20 from one of the corners toward the center of the display panel 20.

[0105] The remote controller 120 may include an up / down button 75. The up / down button 75 is located in the center of the display panel 20. The up / down button 75 includes a first button 76 and a second button 77. The first button 76 raises the bottom 80. The second button 77 lowers the bottom 80. The first button 76 is displayed adjacent to the second button 77. The first button 76 and the second button 77 raise or lower the part of the bottom 80 that is pressed by the first switch button 71, the second switch button 72, the third switch button 73, or the fourth switch button 74. For example, when the first switch button 71 is pressed, the first button 76 and the second button 77 raise or lower the back bottom 81. For example, when the second switch button 72 is pressed, the first button 76 and the second button 77 raise or lower the foot bottom 84. Arrows may be displayed on the first button 76 and the second button 77. The arrows correspond to the direction in which the bottom 80 is raised. The direction of the arrows corresponds to the direction in which the bottom 80 is raised or lowered. Pressing the upward arrow raises or raises the bottom 80. Pressing the downward arrow lowers or lowers the bottom 80.

[0106] The area of ​​the first button 76 may be the same as the area of ​​the second button 77. The areas of the first button 76 and the second button 77 may divide the area of ​​the tilt button 75 in the first direction D1. The boundary B4 between the first button 76 and the second button 77 is the midpoint of the area of ​​the tilt button 75 in the first direction D1. This makes it easier to tilt the bottom 80. Fine adjustment of tilting is possible. Faster operation is possible when raising or lowering the bottom 80.

[0107] The body part switching button 70 may display the angle of the bottom 80 for the target body part. For example, the first switching button 71 may display the angle of the back bottom 81. For example, the second switching button 72 may display the angle of the foot bottom 84. The body part switching button 70 may also display the degree of height of the bottom 80. For example, the fourth switching button 74 may display the height of the bottom 80. The degree of tilt of the bottom 80 may be displayed in 10 steps. For example, step 1 may be 13° and step 2 may be 26°. The first switching button 71 may also be a button to switch the tilt of the foot bottom 84 or the knee bottom 83. The second switching button 72 may also be a button to switch the tilt of the back bottom 81 or the knee bottom 83.

[0108] The degree to which the bottom 80 is tilted may be displayed pictograms within the tilt button 75 by a model display 29. In the model display 29, for example, when the back bottom 81 is at a steep angle, the part of the model display 29 corresponding to the back bottom 81 is at a steep angle. The model display 29 may be displayed in at least a first color and a second color. For example, when the first switching button 71 is pressed, the back bottom 81 is displayed in the first color, and the knee bottom 83 and foot bottom 84 other than the back bottom 81 are displayed in the second color.

[0109] Furthermore, the angle of the bottom 80 at the target part may be displayed within the tilt button 75. For example, when the first switching button 71 is selected, the angle of the target back bottom 81 may be displayed numerically, as a pictogram as described above, or both.

[0110] The remote controller 120 may include a vibration unit 50, an announcement unit 51, and a control unit 52. The vibration unit 50 vibrates when the body part switching button 70 is pressed. The announcement unit 51 makes an announcement by voice when the body part switching button 70 is pressed.

[0111] Figures 15, 16, and 17 are schematic side views of a remote controller according to this embodiment. In the remote controller 120, as shown in Figures 15, 16, and 17, the housing 10 includes one surface 10a and another surface 10b. For example, one surface 10a is the front surface of the remote controller 120, and the other surface 10b is the back surface of the remote controller 120. The display panel 20 is provided on one surface 10a. As shown in Figures 15 and 16, the height 11h of the edge 11 of the housing 10 on one surface 10a may be different from the height 20h of the display panel 20.

[0112] For example, as shown in Figure 15, the height 11h of the edge 11 of the housing 10 may be lower than the height 20h of the display panel 20. The display panel 20 protrudes from the housing 10 in the third direction D3. For example, as shown in Figure 16, the height 11h of the edge 11 of the housing 10 may be higher than the height 20h of the display panel 20. The housing 10 is recessed on one surface 10a. This makes it easy to grasp the corners of the display panel 20 and makes the arrangement of operation buttons within the display panel 20 clearer. As a result, improved operability such as touch typing is possible. On the other hand, as shown in Figure 17, the height 11h of the edge 11 of the housing 10 on one surface 10a may be the same as the height 20h of the display panel 20.

[0113] <Modification of the Fourth Embodiment> Figure 18 is a schematic diagram of a remote controller according to a modification of the fourth embodiment. The remote controller 121 may include a first memory button 78 and a second memory button 79, as shown in Figure 18. The first memory button 78 and the second memory button 79 are provided in the corners of the display panel 20. The first memory button 78 and the second memory button 79 record the upright and upright positions and heights of the bottom 80. If the current angle of the back bottom 81 is 45°, the angle of the foot bottom 84 is 15°, and the height of the bottom 80 is 25 cm, pressing the first memory button 78 or the second memory button 79, for example by long-pressing, will store those angles and their heights. Subsequently, if the angle of the back bottom 81 is set to 30°, the angle of the foot bottom 84 to 10°, and the height of the bottom 80 to 10 cm, and the first memory button 78 is pressed by short-pressing, the angle of the foot bottom 84 will be 15° and the height of the bottom 80 will be 25 cm.

[0114] The housing 10 may include a protrusion 12 on its edge 11. The protrusion 12 is, for example, a projection that extends in a third direction D3. The position of the protrusion 12 corresponds to the positions of the first memory button 78 and the second memory button 79.
