(first embodiment)

Fig. 1(a) to 1(c) are schematic perspective views illustrating an electric furniture according to a first embodiment.

As shown in fig. 1(a), the electromotive furniture 310 of the first embodiment includes a controlled part 70C. The controlled part 70C includes, for example, a movable part 70. The controlled unit 70C may include at least one of the movable unit 70, the illumination unit 73a, and the temperature control unit 73b (e.g., a heater). In this example, the electric furniture 310 is provided with the control device 160. The control device 160 can control the movable portion 70 of the electric furniture 310. Control device 160 is, for example, a remote control for motorized furniture 310. The control device 160 is, for example, a hand switch. The control device 160 may have various functions such as an illumination on/off function, a call function of a caregiver or a caregiver, and a power on/off function.

The electromotive furniture 310 is used in a hospital, a care facility, a home, or the like, for example.

In this example, the motorized furniture 310 is a motorized bed. The electric bed has a movable portion 70. The movable portion 70 includes, for example, a back rest 70a, a knee rest 70b, a leg rest 70c, a height changing portion 70d (e.g., a bed lifter), and the like. The angles of the back rest plate 70a, the knee rest plate 70b, and the leg rest plate 70c can be changed. The angle of the back of the user can be changed by the operation of the back splint 70 a. By changing the angle between the knee plate 70b and the leg plate 70c, the angle of the knee can be changed. These angles may also be changed in conjunction. The height changing unit 70d can change, for example, the distance (height) between the floor surface and the bed surface. The height changing unit 70d may change the height of the head side of the bed and the height of the foot side of the bed independently. This makes it possible to change the inclination of the entire bed surface. For example, an actuator is used as the movable portion 70. By the operation of the movable portion 70, at least one of "back rising", "knee rising", "height adjustment", and "tilt" can be performed. The "tilt" includes at least one of a heave and a warp.

the control device 160 is electrically connected to the movable portion 70. A control circuit may be provided between the control device 160 and the movable portion 70. In this way, the case where another circuit is provided in the middle is also included in the electrically connected state.

as shown in fig. 1(a), the control device 160 is connected to the electric furniture 310 via a cable 15. Control device 160 may also be connected to powered furniture 310 via wireless communication. The control device 160 includes an operation unit 10.

As shown in fig. 1(b) and 1(c), the control device 160 (operation unit 10) has a first surface 10a and a second surface 10 b. The second surface 10b is a surface opposite to the first surface 10 a. The first surface 10a is, for example, a front surface. The second surface 10b is, for example, a back surface. The first surface 10a is, for example, an operation surface.

The control device 160 includes a first operation receiving unit 20 (e.g., a plurality of operation buttons), a second operation receiving unit 25 (e.g., a memory button), and a switch 50.

a first operation receiving portion 20 (e.g., a plurality of operation buttons) and a second operation receiving portion 25 (e.g., a memory button) are provided on the first surface 10 a. The switch 50 is provided, for example, in a portion other than the first surface 10 a. In this example, the switch 50 is provided on the second surface 10 b. The switch 50 may be provided on a side of the housing of the control device 160.

The first operation receiving unit 20 and the second operation receiving unit 25 use, for example, switches (e.g., buttons) having mechanical contacts. As the first operation receiving unit 20 and the second operation receiving unit 25, any input device (for example, a touch switch) such as an electrostatic input device or an optical input device may be used.

The first operation receiving unit 20 (e.g., a plurality of operation buttons) and the second operation receiving unit 25 (e.g., a memory button) can receive a control operation for controlling the operation of the movable portion 70 of the electromotive furniture 310.

The movable unit 70 is controlled based on the control operations received by the first operation receiving unit 20 and the second operation receiving unit 25. The movable portion 70 is operated by operating the first operation receiving portion 20. The movable unit 70 is brought into a stored state by operating the second operation receiving unit 25. The stored state is stored in the storage unit 48 (see fig. 1 a), for example.

In this example, the first operation receiving portion 20 (for example, a plurality of operation buttons) includes a rise button 21a related to "interlock", a fall button 21b related to "interlock", a rise button 22a related to "head", a fall button 22b related to "head", a rise button 23a related to "foot", a fall button 23b related to "foot", a rise and fall button 24a related to "height", a fall button 24b related to "height", and the like.

For example, when the up button 22a associated with the "head" is pressed, the angle of the back splint 70a becomes large. For example, when the lowering button 22b associated with the "head" is pressed, the angle of the back splint 70a becomes smaller. For example, when the rising button 23a related to "foot" is pressed, the angle of the knee brace 70b and the leg brace 70c becomes larger. For example, when the lowering button 23b related to "foot" is pressed, the angle of the knee brace 70b and the leg brace 70c becomes smaller. These angles are, for example, angles relative to the horizontal. For example, when the up button 24a associated with "height" is pressed, the bed surface becomes high. For example, when the down button 24b associated with "height" is pressed, the bed surface becomes low. For example, when the up button 21a associated with "interlock" is pressed, the "head" and "foot" change in interlock. For example, when the down button 21b associated with "interlock" is pressed, "head" and "foot" change in interlock. These changes are performed by the operation of the movable portion 70. For example, the above-described operation is performed while the first operation receiving unit 20 continues to receive the operation (for example, while the operation button continues to be pressed). This enables a safe operation.

In this example, a plurality of buttons (a button 25a related to the first memory location, a button 25b related to the second memory location, and the like) are provided as the second operation receiving portion 25. The number of the plurality of buttons to be the second operation receiving portion 25 may be three or more.

When the button 25a is pressed, a first memory location is formed. When button 25b is pressed, a second memory location is formed. The first memory position corresponds to one state of a combination of the states of the back splint 70a, the knee splint 70b, the leg splint 70c, and the height changing portion 70 d. The second memory position corresponds to another state of the combination of the states of the back rest plate 70a, the knee rest plate 70b, the leg rest plate 70c, and the height changing portion 70 d.

The second operation receiving unit 25 (the button 25a and the button 25b) can form a desired posture. The desired posture is stored in the storage unit 48. Further, the order of the operation of the movable portion 70 until the desired posture is reached may be stored. The movable portion 70 operates in the stored order.

The control of the movable portion 70 by the second operation receiving portion 25 (e.g., memory button) is simpler than the control of the movable portion 70 by the first operation receiving portion 20 (e.g., a plurality of operation buttons). The second operation receiving unit 25 (e.g., memory button) improves usability.

The second operation receiving portion 25 (e.g., memory button) is adapted to be operated by a user of the electric furniture 310, for example. The second operation receiving unit 25 may be operated by a caregiver (such as a nurse) of the user of the electric furniture 310.

on the other hand, at least a part of the plurality of first operation receiving portions 20 (e.g., a plurality of operation buttons) can independently control each of the plurality of movable portions 70. This enables fine control of a desired state. Therefore, the plurality of first operation receiving units 20 are suitable for being operated by a caregiver (a nurse or the like).

by providing the second operation receiving portion 25 (e.g., memory button), the user of the electric furniture 310 (e.g., electric bed) can be prompted to more actively operate the movable portion 70. By providing the second operation receiving portion 25 in addition to the first operation receiving portion 20, it is easier to use both the user and a caregiver of the user, for example.

The storage of the state of the movable portion 70 in the storage portion 48 may be automatically performed. Alternatively, the storage of the state of the movable portion 70 in the storage portion 48 may be manually performed. For example, the switch 50 is used when the state of the movable portion 70 is manually stored.

For example, the control device 160 may be provided with an operation mode and a storage mode. These modes can also be switched by operation of the switch 50. For example, in the operation mode, the movable portion 70 is operated by operating the first operation receiving portion 20 and the second operation receiving portion 25. By operating the switch 50, the mode can be shifted to the storage mode. By operating the first operation receiving unit 20 in this storage mode, the movable unit 70 is brought into a desired state. For example, in this state, by pressing the second operation receiving portion 25 (the button 25a or the button 25b), the state of the movable portion 70 at this time is stored in the storage portion 48. By pressing the switch 50 again, the operation mode is returned to. In the operation mode, the stored state of the movable portion 70 is formed by operating the second operation receiving portion 25. As described above, in the embodiment, the state of the movable portion 70 may be stored using the switch 50.

the switch 50 can be used for any control other than the switching of the modes as described above. As the switch 50, for example, a hardware switch, a switch controlled by software, or the like can be used.

On the other hand, when the state of the movable portion 70 is automatically stored in the storage portion 48, the state of the user of the electric furniture 310 is detected by a detection portion (described later), for example. The detection unit may be provided in the electromotive furniture 310 or may be provided separately from the electromotive furniture 310. Then, it is determined (estimated) whether or not the detected state of the user is a predetermined state. The predetermined state is, for example, rising, sitting up (for example, a state of getting out of bed ready), getting out of bed, falling asleep, sleeping, or waking up (but lying in bed 70). When it is determined (estimated) that the state of the user is a predetermined state, the state of the movable portion 70 at that time is stored in the storage portion 48. At this time, when the second operation receiving portion 25 (for example, a memory button) receives an operation (for example, a memory button is pressed), the operation is automatically stored in the movable portion 70 of the storage portion 48.

In the embodiment, the movable portion 70 is automatically (not manually) operated based on the state of the user detected by the detection portion.

For example, as described above, when the first operation receiving portion 20 or the second operation receiving portion 25 receives a control operation, the movable portion 70 operates. This is a manual action. In the embodiment, even if the first operation receiving portion 20 or the second operation receiving portion 25 does not receive the control operation, the movable portion 70 operates based on the state of the user detected by the detection portion. That is, the electric furniture 310 is provided with the control unit 42 (see fig. 1 (a)). The control unit 42 controls the controlled unit 70C (the movable unit 70 in this example) based on the state of the user detected by the detection unit. That is, the control unit 42 can perform "movable unit control" for operating the movable unit 70 based on the state of the user detected by the detection unit. Thereby, the operation becomes simpler. Provided is an electric furniture which can improve the convenience of use.
