The communication unit 75 communicates with the communication unit of the external device. The control unit 76 controls the drive unit 74 and the communication unit 75.

  Next, the support operation by the support system 1 will be described based on the flowcharts shown in FIGS. Below, the operation in the case where the user of the bed apparatus 2 carries out the support action for preparing for transfer to the wheelchair 60 will be described.

First, as shown in FIG. 8, the position of the user on the bed apparatus 2 is detected (step S1). At this time, based on the detection result of the detection unit 43 of the first additional function unit 40, the control unit 46 of the first additional function unit 40 calculates (acquires) the barycentric position of the user on the bed apparatus 2.
Next, it is determined whether or not the position of the user detected in step S1 is out of a predetermined range determined in advance (step S2). At this time, the control unit 46 of the first additional function unit 40 determines whether or not the barycentric position of the user has deviated from the predetermined range. For example, when the user is lying on the bed apparatus 2, the distribution of the center of gravity of the user on the bed apparatus 2 is a regular deviation of the standard deviation σ with the center part in the short direction of the bed 11 as μ. When the distribution is followed, the predetermined range can be set within a range of positions separated by 2σ in the lateral direction from the central portion.

If it is determined in step S2 that the barycentric position of the user is not out of the predetermined range (NO), the process returns to step S1. By performing steps S1 and S2 for each predetermined unit time, the control unit 46 of the first additional function unit 40 monitors the trajectory of the barycentric position of the user on the bed apparatus 2.
On the other hand, if it is determined in step S2 that the barycentric position of the user has deviated from the predetermined range (YES), it is determined that the user is preparing for leaving (transfer and movement) from the bed, as shown in FIG. The support process shown is implemented (step S3).

In the support step, first, the position of the user on the bed apparatus 2 is detected as in step S1 (step S31). Then, as in step S2, it is determined whether the position of the user detected in step S31 is out of the predetermined range (step S32).
If it is determined in step S32 that the barycentric position of the user is out of the predetermined range (YES), the first support means 7 and the second support means 8 perform a support action (step S33). The first support means 7 and the second support means 8 perform a support action when the detection unit 43 of the first additional function unit 40 detects an input.
At this time, first, from the communication unit 45 of the first additional function unit 40, to the communication unit 15, 35, 65, 75 of the bed apparatus body 10, the support bar 30, the wheelchair 60, and the care lift 70, the barycentric position of the user Send information about The couch device body 10, the assistance bar 30, the wheelchair 60, and the care lift 70 perform the following operations.

The control unit 16 of the bed apparatus body 10 controls the drive unit 14 to raise and lower the elevating fence 13 according to the gravity center position of the user (step S33a). The lowering of the lifting fence 13 prevents the lifting fence 13 from disturbing the user's leaving the floor.
The control unit 56 of the second additional function unit 50 controls the drive unit 54 to rotate the movable unit 32 according to the gravity center position of the user (step S33 b). The rotation of the movable portion 32 prevents the movable portion 32 from disturbing the user's leaving the floor.

The control unit 66 of the wheelchair 60 controls the drive unit 64 to move the wheelchair 60 according to the gravity center position of the user (step S33 c). When the wheelchair 60 approaches the bed apparatus 2, the user can easily transfer to the wheelchair 60, and the burden on the assistant can be reduced.
The control unit 76 of the care lift 70 controls the drive unit 74 to raise and lower the hanger in accordance with the gravity center position of the user (step S33 d). By rotating the lifting gear, the user can easily transfer from the bed apparatus 2 to the lifting gear, and the burden on the assistant can be reduced.
The control unit 16 of the bed apparatus body 10 controls the drive unit 14 to move the bed 11 up and down according to the gravity center position of the user (step S33 e). By placing the bed 11 at an optimum height for the user and the assistant, the burden on the user and the assistant can be reduced.

  After step S33, each of the first support means 7 and the second support means 8 determines whether the support action has been completed (step S34). For example, it can be determined as follows whether the support action has been completed. That is, the control unit that controls each of the support means 7 and 8 determines whether or not the support action by the support means is completed, and when it is determined that the support action has been completed, The completion information is sent to the control unit 46 of the additional function unit 40. The control unit 46 of the first additional function unit 40 determines that the support action by each of the support units 7 and 8 is completed when the completion information is acquired for all the support units 7 and 8.

  In addition, for example, the state where the support action of the drive unit 14 of the bed apparatus body 10 is completed can be a state where the lifting fence 13 has been lowered. The state in which the support action of the drive unit 54 of the second additional function unit 50 is completed can be a state in which the movable unit 32 has finished rotating. The state where the support action of the drive unit 64 of the wheelchair 60 is completed can be a state where the wheelchair 60 approaches the bed apparatus 2 up to a predetermined distance. The state in which the support action of the drive unit 74 of the care lift 70 is completed can be a state in which the lifting gear has been lowered.

If it is determined in step S34 that the support action has been completed (YES), the support process is ended. In this case, it is assumed that the support process has ended normally. If it is determined in step S34 that the support action has not been completed (NO), the process returns to step S31. By performing steps S31 to S34 for each predetermined unit time, the control unit 46 of the first additional function unit 40 monitors the locus of the gravity center position of the user on the bed apparatus 2, and supports each support unit 7, 8 is controlled in coordination with the gravity center position of the user. This cooperative control can prevent, for example, unexpected contact between the user and each configuration.
If it is determined in step S32 that the position of the center of gravity of the user is not out of the predetermined range (NO), that is, if it is determined that the position of the center of gravity of the user has returned within the predetermined range, each support means 7 , 8 are returned to the origin (step S35). In this case, by performing step S35, the support process ends. At this time, it is assumed that the support process ends abnormally.

As shown in FIG. 8, after step S3 (supporting process) is completed, it is determined whether the supporting process has ended normally (step S4). The control unit 46 of the first additional function unit 40 determines whether the support process has ended normally based on whether the support process ended normally or abnormally.
If it is determined in step S4 that the support process has ended normally (YES), a series of support actions are ended, and if it is determined that the support process has not ended normally (NO), the process returns to step S1.

  In addition, even after the above-mentioned support action ends normally, it is possible for each support means 7 and 8 to carry out further support action for the user. As further support actions, for example, support for an operation for the user to be at the end position, start-up support, leaving-off support, transfer support and the like can be mentioned. For example, in the case of standup support, when the user grips the handrail portion 32a of the assistance bar 30 to stand up, the detection unit 43 detects the direction of the grip and the press, and the drive unit 14 rotates the movable unit 32. The control unit 16 can be controlled to assist the operation.

As described above, according to the support system 1 and the couch device 2 according to the present embodiment, the couch device 2 includes the additional function unit 5. Therefore, it becomes possible to add an additional function to be exerted by the additional function unit 5 to the bed apparatus 2, and it is possible to achieve multifunctionalization of the bed apparatus 2.
The power supply unit 6 for the additional function unit 5 supplies power to the additional function unit 5. Therefore, it is not necessary to supply power from the outside of the bed apparatus 2 in order to add an additional function to the functional component 4. As a result, it is possible to suppress the occurrence of unnecessary wiring while adding an additional function to the functional component 4.
Since the power supply unit 6 is for the additional function unit 5, by using the power supply unit 6 as a dedicated power supply for the additional function unit 5, the function of the additional function unit 5 can be stably exhibited or the power supply unit 6 can be small. Capacitance and miniaturization can be achieved.

It can be made easy.

The second power supply unit 6 b is provided in the bed apparatus body 10. Therefore, for example, the weight of the assistance bar 30 can be reduced as compared with the case where the second power supply unit 6 b is provided in the assistance bar 30 (functional component 4). Thereby, the attachment property to the bed apparatus main body 10 of the assistance bar 30 can be improved.
The additional function unit 5 receives power from the second power supply unit 6 b via the mounting power supply unit 19 and the mounting power reception unit 39. Therefore, when attaching the assistance bar 30 to the bed apparatus main body 10, the power of the second power supply 6b can be supplied to the additional function unit 5 simply by attaching the attachment power receiving unit 39 to the feed unit 19. As a result, it is possible to improve the mountability of the care bar 30 to the bed device main body 10 and to effectively suppress the occurrence of unnecessary wiring.

The first additional function unit 40 is detachably provided on the board 20 (functional component 4). Therefore, for example, when the board 20 is attached to the bed apparatus body 10, the first additional function unit 40 can be detached from the board 20, and the attachability of the board 20 to the bed apparatus body 10 is improved. Can do things like
