  Unlike a hospital bed, a care bed is required to be small and light because there are restrictions on the installation location. In consideration of ease of carrying in and installation, the bed is generally divided into parts so that it can be easily assembled and disassembled.

  In addition, a technology is known in which the height of the bed device can be changed such that the user can move it to a low position so that the user can easily transfer from the bed device, or the user can raise the bed device so that the user can easily perform nursing care. (For example, refer to Patent Document 1).

  In the case of a care bed, the user may operate the care bed or the caregiver, but both the user and the caregiver may be unfamiliar with the operation. Therefore, in order to prevent an inadvertent misoperation, a bed apparatus in which a power button is mounted on a hand switch is known (for example, see Non-Patent Document 1). By operating the power button, the operation can be locked (prohibited) in the standby state. That is, in the standby state, operations using the operation buttons that are operation input means are prohibited.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. The following embodiments describe the necessary and sufficient state for explaining the present invention, and the contents of the present invention are not limited by the embodiments.

[1. Overall overview]
FIG. 1 is an overall view of a bed apparatus 1 according to the present invention. In the bed apparatus 1, a bed operation apparatus 5 is connected to the bed apparatus body 3. In the present embodiment, the bed operating device 5 is connected to a control unit (not shown) provided in the bed device main body by wire, but may be connected wirelessly.

  Here, the bed apparatus main body 3 will be briefly described. FIG. 2 is an overall perspective view of the frame on which the bottom is mounted in the bed apparatus main body 3.

  In FIG. 2, in the bed apparatus, the head side of the sleeping user facing the head is denoted by “H”, and the foot side facing the user's foot is denoted by “F”. Further, the right hand side (left side of the bed apparatus top view) when the user is in the supine position is denoted by “R”, and the left hand side (right side of the bed apparatus top view) when the user on the opposite side is in the supine position is denoted by “L”. ".

  As shown in FIG. 2, the bed apparatus mainly includes an upper frame 10 having a generally ladder-like structure in which the longitudinal direction with the ends facing the head side and the foot side is longer than the short direction (width direction), and the upper frame 10. A bottom (not shown) placed on the upper frame 10 and an elevating unit 14 (provided respectively on the lower side of the head side and the foot side of the upper frame 10 for supporting the upper frame so as to be movable up and down on the floor surface) A head-side lifting unit 14H and a foot-side lifting unit 14F).

  A frame frame 16 having a substantially rectangular frame shape that is long in the width direction of the bed apparatus for installing the upper frame on the upper ends of the elevating parts 14H and 14F on the lower surface side of each part on the head side and the foot side of the upper frame. A frame frame 16H is fixed to the elevating part 14H, and a frame frame 16F is fixed to the elevating part 14F.

  The lower ends of the elevating parts 14H and 14F are detachably connected by a connecting frame 18. The connection frame 18 is a pair of pipe-like frame structures, and has a structure in which the length direction of the connection frame 18 extends along the head side and the foot side.

  Each of the elevating units 14H and 14F is provided with a driving device (for example, an actuator), and the driving force of each actuator is controlled separately. By the drive control of each actuator, the upper frame can be tilted so as to have a difference in the vertical position between the head side and the foot side.

[2. Functional configuration]
Subsequently, the functional configuration of the bed apparatus 1 in the present embodiment will be described with reference to the drawings. FIG. 3 is a diagram for explaining an outline of the functional configuration of the bed apparatus.

  In the bed apparatus, a drive control unit 200, a state detection unit 300, a storage unit 400, and an operation display unit 500 are connected to the control unit 100, respectively.

The control unit 100 is a functional unit for controlling the entire bed apparatus. The control unit 100
Various functions are realized by reading and executing various programs stored in the storage unit 400, and for example, a CPU (Central Process Unit) is configured.

  The drive control unit 200 is a functional unit for controlling a drive unit (drive device, which is an actuator in this embodiment) provided in the bed apparatus. The drive control unit 200 is provided in the bed apparatus as a control unit, for example.

  The drive control unit 200 will be described with reference to FIG. As shown in FIG. 4, the drive control unit 200 includes a bottom control unit 210 for controlling the functions of raising the back, raising the knee (footing), etc. by operating the bottom, and the height of the bed apparatus. A function with the height control unit 220 for controlling is realized.

  In order to realize the back raising function, the bottom control unit 210 is connected to the back bottom drive unit 212 and the knee bottom drive unit 214. The back bottom drive part 212 is the actuator 36 in FIG. 2, and is connected to the link 20 for raising the back via a link mechanism. Then, under the control of the back bottom drive unit 212, the back bottom 42 placed by the link 20 is operated, and back raising / lowering control is performed.

  Further, the knee bottom driving unit 214 is the actuator 38 in FIG. 2, and is connected to the knee-raising link 22 via a link mechanism. Then, under the control of the knee bottom drive unit 214, the knee bottom 46 placed on the link 22 and the further connected foot bottom 48 operate to perform knee-up / knee-down (foot-down / foot-up) control. Is called.

  Further, the user P has an upper body supported by the back bottom 42 and a waist supported by the waist bottom 44. Further, the knee bottom 46 and the thigh of the user P are in contact with each other and supported, thereby preventing the user P from moving in the foot side direction F, for example.

  The height control unit 220 controls the height of the bed, and the head side driving unit 222 and the foot side driving unit 224 are connected. The head-side drive unit 222 is the actuator 32 in FIG. 2 and realizes the lifting function of the lifting unit 14H. Moreover, the foot side drive part 224 is the actuator 34 in FIG. 2, and implement | achieves the raising / lowering function of the raising / lowering part 14F. By controlling the head-side drive unit 222 and the foot-side drive unit 224 by the same control amount (that is, the heights of the elevating unit 14H and the elevating unit 14F are the same height), the horizontal state is maintained. It is possible to change the height of the bed apparatus.

  Further, the head device 222 and the foot drive unit 224 are controlled by different control amounts (that is, the heights of the lift unit 14H and the lift unit 14F are set to different heights), thereby tilting the bed apparatus. The operation can be realized and the bed can be tilted.

  The state detection unit 300 is a functional unit for detecting the state of the entire bed apparatus. For example, it detects the state of the bed device (whether the back is raised, etc.), detects the current height of the bed device, and detects whether the user is currently on the bed device, etc. I can do it.

  The state detection unit 300 may be detected using various sensors, or may be detected based on a signal received by the actuator. For example, when detecting the back raising angle, the correlation between the amount by which the actuator 36 is operated (the amount of the extended rod) and the back raising angle is stored in advance. As a result, by detecting the current state of the actuator 36, the back raising angle raised by the actuator 36 can be detected.

  Furthermore, the correlation between the amount by which the actuator 32 (34) is operated and the lifting unit 14H (14F) is stored in advance. Thereby, the current height and inclination angle of the upper frame 10 can be detected.

  For convenience of explanation, it will be described that the state detection unit 300 performs detection of various states, but the control unit 100 may perform all of them.

  The storage unit 400 is a functional unit that stores various programs and various data necessary for the operation of the bed apparatus. The storage unit 400 is configured by, for example, a semiconductor memory, an HDD (Hard Disk Drive), or the like.

  The operation display unit 500 is a functional unit that performs an operation input to the bed apparatus 1 (the bed apparatus body 3), and realizes a back raising / knee raising (foot raising) function or adjusts the height of the bottom. Function is realized. Further, as the current state of the bed apparatus main body 3, the back raising angle, the height of the bed, the current operation mode, and the like are displayed. The operation display unit 500 is the bed operation device 5 in FIG.

  Here, the bed operation device 5 (operation display unit 500) will be described with reference to FIG. As shown in FIG. 5, the bed operation device 5 includes a display unit 510 and an operation button 520 as an operation input unit.

  The display unit 510 displays various information such as the current operation status and the bed state. For example, it is composed of a liquid crystal panel, an organic EL panel, or the like.

  The operation button 520 is a functional unit (operation input means) for instructing the bed apparatus body 3 to perform various operations. For example, in the present embodiment, “interlocking” in which the back raising and the leg raising operate together, the “head” for performing the back raising operation, the “foot” for performing the knee raising (leg lowering) operation, the bed apparatus main body 3 With regard to the “height” for changing the height (elevating operation), “up” and “down” operations can be performed.

  For example, when it is desired to perform a back-up operation, the user selects (presses) the button 522. Further, when the user wants to perform the back-lowering operation, the user selects (presses) the button 524.

  Further, in the present embodiment, a power lamp 530 is provided. When the power lamp 530 is lit, the power is turned on, that is, by selecting the button 522, the bed apparatus can be operated.

  The state where the power is turned on is an energized state where the bed apparatus main body can be operated. Note that it is only necessary to control the “state in which the bed can be operated” and the “state in which the bed cannot be operated”. That is, not only the power is turned on, but various operation restrictions may be realized by an operation lock or the like.

[3. Process flow]
The process in this embodiment is demonstrated using FIG.

  First, the power supply is in a standby state (step S102). Here, the standby state refers to a case where power is supplied through, for example, a power cable, but an operation is not possible. That is, the bed operation is restricted by the user.

Subsequently, it is detected whether or not a button has been selected (step S104). Specifically, it is detected that any of the buttons 522 is selected. At this time, only one button may be detected. That is, when two or more buttons are detected, the buttons may not be detected as being selected.

  Subsequently, when it is detected that the selected state of the button has been released (step S106; Yes), the power is turned on (step S108). That is, when the button 522 is selected and the selection of the button 522 is released, the power is turned on (that is, an operable state). For example, when the power lamp 530 is turned on at this time, the user is notified that the power is turned on, or the display unit 510 is displayed to inform the user that the power is turned on. To do.

  Subsequently, when it is detected that a button has been selected from this state, an operation corresponding to the selected button is executed (step S110; Yes → step S112).

  It is determined whether a predetermined time has passed in a state where the button is not selected (step S110; No) or a state where the operation is finished (step S114).

  Here, when the predetermined time has not elapsed, the processing is repeatedly executed from step S110 again, and when the predetermined time has elapsed, the power supply is shifted to the standby state (step S114; Yes → step S102).

  Here, the predetermined time is a time for the power source to transition to the standby state, and may be a preset time or may be arbitrarily set by the user. In addition, as the elapse timing of the predetermined time, normally, the time during which the no-operation state continues (that is, the time repeated as Step S110; No → Step S114; No → Step S110; No →...) Has elapsed for the predetermined time. It is determined whether or not.

  In addition, the start time for determining whether or not the predetermined time has elapsed may be a time when the above-described no-operation state is continued. In this case, once the operation is executed in step S112, the timer is reset at that timing.

[4. Example of operation]
A specific operation example will be described. For example, FIG. 7 is a state transition diagram of this embodiment. First, when the main power supply is turned on from the OFF state (not connected to the power source, etc.) (separately turned on by the main power operation switch, the power cable is connected to the outlet, etc.), the standby state is entered. Transition. Further, when the main power is turned off from the standby state (separately turned off by the main power operation switch, the power cable is disconnected from the outlet, etc.), the state transits to the OFF state.

  When the operation button is selected in the standby state and the selected state is released, the state is changed to the ON state. In the ON state, the ON state is maintained while the operation is performed. Here, when a predetermined time elapses without any operation, a transition is made to a standby state.

  When the main power is turned off in the ON state (separately turned off by the main power operation switch, the power cable is disconnected from the outlet, etc.), the state changes to the OFF state.

  In this way, the transition from the OFF state to the standby state is performed before the transition to the ON state. Moreover, in order to make a transition from the standby state to the ON state, the button device is selected and turned ON at the release timing, so that it is possible to prevent the bed apparatus body from operating due to an erroneous operation.

  Furthermore, since the power can be turned on with the operation button instead of the power button, it is possible to provide a user-friendly operation.

  Thus, in this embodiment, it will be in the state where the restriction | limiting which can perform the operation | movement of a bed at the time of ON state is cancelled | released. Further, the bed operation is restricted in the standby state. Moreover, since it is not energized in the OFF state, the operation cannot be performed.

  FIG. 8 is a diagram schematically showing a part of the bed operating device 5. FIG. 8 shows a state where the bed apparatus is not turned on (standby state). At this time, the user selects the operation button 526.

  FIG. 9 is a diagram showing a state in which the selection state of the operation button 526 selected in FIG. 8 is released. When the operation button 526 is released from the selected state, the power is turned on. Here, “ON” is displayed on the display unit 510, and the power lamp 530 is lit.

  FIG. 10 is a diagram showing an operable state. FIG. 11 shows that the button 526 is selected again from this state. For example, in FIG. 10, the back raising angle is “60” degrees, but in FIG. 11, it is “65” degrees.

  FIG. 12 shows a state where the operation of the bed apparatus is locked. Therefore, “Operation locked” is displayed on the display unit 510. At this time, the user selects the operation button 526.

  FIG. 13 is a diagram illustrating a state where the selection state of the operation button 526 selected in FIG. 12 is released. When the operation button 526 is changed from the selected state to the released state, the lock is released and the operation can be performed. Here, “cancel” is displayed on the display unit 510, and the operable lamp 535 is lit.

[5. Other embodiments]
Next, another embodiment will be described. In the above-described embodiment, it has been described that the power is turned on (becomes operable) when the operation button is selected and released.

  Here, an example will be described in which, when the first operation button is selected, when the button is selected for a predetermined time or more, the power is turned on (becomes operable) at the release timing thereafter. .

  Specifically, in step S104 in FIG. 6, the timing for detecting the selection of the button may be set to a predetermined time. For example, when the predetermined time is “3 seconds”, if the selection state of the button is maintained for 3 seconds (for example, when the button is kept pressed for 3 seconds), it may be detected that the button is selected.

  Thus, for example, when the power is turned on (operable), it is necessary to continue to select the same operation button for a predetermined time or longer. Therefore, it is possible to provide a bed operation device with higher safety.

  In addition, turning on the power means that it is in an “operable state”. Therefore, even if the button is selected and then released and then shifted to the operable state, the same effect is obtained.

  That is, as shown in FIG. 14, the power may be turned on in a state where an arbitrary button (for example, a button to be operated) is selected (pressed) in the “standby state”. However, other operations cannot be performed in this state. That is, by canceling this selection state, it is possible to change to the “operable state” and perform various operations.

  Then, when a predetermined time has elapsed in the “operable state”, the state may transition again to the “standby state”. Thus, it is not necessary for the user to bother operating the power button, and by preventing erroneous operation, it is possible to provide a highly convenient and highly safe bed operating device.

[6. Modified example]
The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and the design and the like within the scope of the present invention are also within the scope of the claims. include.

  In the above-described embodiment, the bed operation device 5 has been described as including the display unit 510, the operation button 520, and the power lamp 530. However, the bed operation device 5 may be integrally formed with, for example, a touch panel.

  Further, the bed operation device 5 may be a wireless connection instead of a wired connection, or may be realized by another device such as a smartphone or a tablet. Specifically, it may be realized by installing an operation application on a smartphone (tablet) and connecting to the bed apparatus using an IP network or the like.
