Embodiments of the present invention will be described below with reference to the drawings.
The drawings are schematic or conceptual, and the relationship between the thickness and width of each part, the size ratio between the parts, and the like are not necessarily the same as actual ones. Even in the case of representing the same part, the dimensions and ratios may be represented differently depending on the drawings.
In the present specification and drawings, the same elements as those described above with reference to the previous drawings are denoted by the same reference numerals, and detailed description thereof is omitted as appropriate.

Drawing 1 (a)-Drawing 1 (c) are typical perspective views which illustrate a control device and electric furniture concerning an embodiment.
As shown in FIG. 1A, the control device 160 according to the embodiment is used together with the electric furniture 310. The control device 160 can control the movable part 70 of the electric furniture 310. The control device 160 is, for example, a remote controller (remote controller) for the electric furniture 310. The control device 160 is a hand switch, for example. The control device 160 may have various functions such as a lighting on / off function, a nurse or caregiver calling function, or a power on / off function.

  The electric furniture 310 is used in, for example, a hospital, a nursing facility, or a home.

  In this example, the electric furniture 310 is an electric bed. The electric bed has a movable part 70. The movable unit 70 includes, for example, a back bottom 70a, a knee bottom 70b, a leg bottom 70c, and a height changing unit 70d (for example, a bed elevator). The angles of the back bottom 70a, the knee bottom 70b, and the leg bottom 70c can be changed. The angle of the user's back can be changed by the operation of the back bottom 70a. The angle of the knee can be changed by changing the angle between the knee bottom 70b and the leg bottom 70c. These angles may change in conjunction. The height changing unit 70d can change the distance (height) between the floor surface and the bed surface, for example. The height changing unit 70d may be able to change independently the height on the head side of the bed and the height on the foot side of the bed. Thereby, the whole inclination of the bed surface can be changed. For these movable parts 70, for example, an actuator or the like is used. By the operation of the movable unit 70, at least one of “back raising”, “knee raising”, “height adjustment”, “inclination”, and the like is possible. “Inclination” includes at least one of rolling and tilting.

  The control device 160 is electrically connected to the movable unit 70 described above. A control circuit may be provided between the control device 160 and the movable unit 70. In this manner, a case where another circuit is provided in between is also included in the state of being electrically connected.

  As shown in FIG. 1A, the control device 160 is connected to the electric furniture 310 by the cable 15. The control device 160 may be connected to the electric furniture 310 by wireless communication. The control device 160 includes the operation unit 10.

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

  The control device 160 includes a plurality of first operation receiving units 20 (for example, operation buttons), a second operation receiving unit 25 (for example, memory buttons), and a switch 50 (switching unit).

  A plurality of first operation reception units 20 (for example, operation buttons) and second operation reception units 25 (for example, memory buttons) are provided on the first surface 10a. For example, the switch 50 is provided in a portion other than the first surface 10a. In this example, the switch 50 is provided on the second surface 10b. The switch 50 may be provided on the side surface of the casing of the control device 120.

  The switch 50 is, for example, a hardware switch or a switch controlled by software. In the following example, a hardware switch is used as the switch 50.

  For the plurality of first operation reception units 20 and the second operation reception unit 25, for example, switches (for example, buttons) having mechanical contacts are used. In addition to the first operation receiving unit 20 and the second receiving unit 25, any input device such as an electrostatic type or an optical type (for example, a touch switch) may be used.

  The plurality of first operation reception units 20 (for example, operation buttons) and the second operation reception unit 25 (for example, memory buttons) can receive an operation for controlling the operation of the movable unit 70 of the electric furniture 310.

  The control device 160 has an operation mode and a storage mode. In the operation mode, the movable unit 70 is controlled by operating the first operation receiving unit 20 and the second operation receiving unit 25. In the storage mode, storage relating to the control of the movable unit 70 is performed.

  The operation mode and the storage mode are switched by the switch 50. For example, when the switch 50 is pressed, the operation mode is switched to the storage mode. At this time, for example, the memory display unit 26 (see FIG. 1B) may be turned on or blinked. By pressing the switch 50 again, the storage mode is switched to the operation mode. For example, in the operation mode, the memory display unit 26 may be turned off.

  In the storage mode, the state of the movable unit 70, the order of control, and the like are stored.

  On the other hand, in the operation mode, the operation of the movable unit 70 of the electric furniture 310 is controlled by operating the plurality of first operation receiving units 20 (for example, operation buttons). Further, in the operation mode, the movable unit 70 is controlled by the operation of the second operation receiving unit 25 (for example, a memory button) according to the state of the movable unit 70 stored in the storage mode and the control order.

  In this example, the plurality of first operation accepting units 20 (for example, operation buttons) are related to an ascending button 21a relating to “interlocking”, a descending button 21b relating to “interlocking”, an ascending button 22a relating to “head”, and a “head”. This includes a descending button 22b, an ascending button 23a for "foot", a descending button 23b for "foot", an up / down button 24a for "height", and a descending button 24b for "height".

  In the operation mode: For example, when the ascending button 22a related to “head” is pressed, the angle of the back bottom 70a increases. For example, when the lowering button 22b related to “head” is pressed, the angle of the back bottom 70a is reduced. For example, when the ascending button 23a regarding the “foot” is pressed, the angles of the knee bottom 70b and the leg bottom 70c increase. For example, when the lowering button 23b related to “foot” is pressed, the angles of the knee bottom 70b and the leg bottom 70c are reduced. These angles are, for example, angles from a horizontal plane. For example, when the ascending button 24a regarding “height” is pressed, the bed surface becomes higher. For example, when the lowering button 24b related to “height” is pressed, the bed surface is lowered. For example, when the ascending button 21a related to “interlocking” is pressed, “head” and “foot” change in conjunction with each other. For example, when the downward button 21b related to “interlocking” is pressed, “head” and “foot” change in conjunction with each other. These changes are performed by the operation of the movable unit 70. For example, the above operation is performed during a period during which the first operation reception unit 20 continues to receive an operation (for example, a period during which the operation button is kept pressed). Thereby, a safe operation is obtained.

  In this example, a plurality of buttons (a button 25a relating to the first memory position, a button 25b relating to the second memory position, etc.) are provided as the second operation accepting unit 25. The number of the plurality of buttons serving as the second operation receiving unit 25 may be three or more.

  In the operation mode: When the button 25a is pressed, the first memory position is formed. When the button 25b is pressed, the second memory position is formed. The first memory position corresponds to one state of a combination of the respective states of the back bottom 70a, the knee bottom 70b, the leg bottom 70c, and the height changing unit 70d. The second memory position corresponds to another state of a combination of respective states of the back bottom 70a, the knee bottom 70b, the leg bottom 70c, and the height changing unit 70d.

  A desired posture can be formed by the second operation receiving unit 25 (button 25a and button 25b). This desired posture can be stored by a user or the like. Furthermore, it is also possible to store the order of movement of the movable part 70 until the desired posture is reached. The movable part 70 moves according to the stored order.

  Control of the movable unit 70 by the second operation receiving unit 25 (for example, a memory button) is simpler than control of the movable unit 70 by a plurality of first operation receiving units 20 (for example, operation buttons). The second operation reception unit 25 (for example, a memory button) improves usability.

  The second operation receiving unit 25 (for example, a memory button) is suitable for being operated by a user of the electric furniture 310, for example. Furthermore, the second operation reception 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 some of the plurality of first operation receiving units 20 (for example, a plurality of operation buttons) can individually control each of the plurality of movable units 70. Thereby, a desired state can be finely controlled. Therefore, the plurality of first operation accepting units 20 are suitable for being operated by a caregiver (such as a nurse).

  By providing the second operation receiving unit 25 (for example, a memory button), it is possible to prompt the user of the electric furniture 310 (for example, an electric bed) to move the movable unit 70 more actively. By providing the second operation receiving unit 25 in addition to the plurality of first operation receiving units 20, for example, both the user and the caregiver of the user can be used more easily.

  Thus, in the embodiment, the movable part 70 includes a bottom part whose angle can be changed and a height changing part 70d whose height can be changed. In the storage mode, the state of the bottom part and the height changing part 70d is formed by the plurality of first operation receiving parts 20 (operation buttons), and the state is stored. In the operation mode, the second operation receiving unit 25 (for example, a memory button) can form the stored state (memory state). In other words, in the operation mode, when the second operation reception unit 25 receives an operation (for example, a memory button is pressed), the storage state is formed. That is, in the operation mode, the second operation receiving unit 25 reproduces at least one of the bottom part and the height changing unit created by the plurality of first operation receiving units 20 in the storage mode.

  For example, when the second operation receiving unit 25 receives an operation, the movable unit 70 moves and a final shape (posture) is obtained. Furthermore, the control order of the plurality of movable parts 70 (bottom part and height changing part 70d) may also be stored. In this case, when the second operation receiving unit 25 receives an operation, the movable unit 70 moves according to the stored order, and a final shape (posture) is formed.

  As already described, the electric furniture 310 is used in, for example, a hospital, a nursing facility, or a home. The user of the electric furniture 310 is a care recipient, for example. The user of the electric furniture 310 is, for example, an elderly person, an injured person (injured person), or a sick person. It is desirable to control the electric furniture 310 (for example, an electric bed) to an appropriate state desired by such a user.

  For example, depending on the user, there may be a case where the predetermined interlocking operation does not result in the intended movement but feels uncomfortable.

  For example, some users have broken legs and hips, and some have contracted joints. In such a user, for example, there may be a part (for example, a joint) that should not be moved. For example, when knee contracture occurs, the electric bed is desired to have an interlocking function that restricts knee motion. For example, there are cases where it is desired to combine a moving joint and a joint that does not substantially move in a desired manner in accordance with the user's condition so that the user can perform a specific action.

  Furthermore, depending on the user, it may be desirable to change the angle of the bottom in the desired order. This is because, depending on the state of the user, pain may be felt if the order of changes in the bottom angle is inappropriate.

  Thus, even when one posture is formed, there is suitability for the user. It has been found that it is important to improve the ease of use to perform the operation reflecting the suitability for the user.

  For example, when a plurality of bottom portions move simultaneously toward the final posture, there is a limit to the improvement of the user's ease of use. Ease of use is greatly improved by the appropriate combination of the order of movement of the plurality of bottom portions and the degree of movement leading to the final posture.

  Further, for example, when the user is an elderly person, an injured person (injured person), or a sick person, the height of the electric furniture 310 is important. For example, when the user moves to the bed or when the user stands up from the bed, it is desirable that the electric bed is somewhat high. This facilitates transfer and rising. On the other hand, when the user is sleeping on the bed, the bed should be low. Thereby, even when falling from the bed, a serious accident (injury, etc.) can hardly occur.

  Therefore, when a cared person such as an elderly person, an injured person (injured person), or a sick person uses the electric bed 310, it is particularly important to adjust the height according to the state of the user. Therefore, by adjusting the height in addition to the angle adjustment, the posture of the electric furniture 310 can be adjusted according to the user's condition, and the usability can be improved.

  As shown in FIG. 1B, a display area 28 may be provided on the first surface 10a. The display area 28 can display, for example, information (such as the bottom angle and height) regarding the movable part 70 of the electric furniture 310. The display area 28 may display information regarding functions or operation states of the plurality of first operation reception units 20 (operation buttons) and the second operation reception unit 25.

  Hereinafter, an example of control of the movable unit 70 by the plurality of first operation receiving units 20 (for example, operation buttons) in the operation mode will be described.

  Drawing 2 (a)-Drawing 2 (e) are mimetic diagrams which illustrate control of electric furniture concerning an embodiment. As shown in FIG. 2A, when the button 22a or the button 22b relating to the “head” is operated, the angle of the back bottom 70a is changed, and the “back raising operation” or “back lowering operation” is performed. .

  As shown in FIG. 2 (b), when the button 22a or the button 22b related to the "foot" is operated, the angles of the knee bottom 70b and the leg bottom 70c change, and the "knee raising operation" or "knee lowering operation" Is performed.

  As shown in FIG. 2C, when the button 24a and the button 24b relating to “height” are operated, the movement of the height changing unit 70d is controlled. Thereby, height adjustment is performed. That is, the height H1 of the bed surface is changed.

  As shown in FIG. 2D, when the button 21a and the button 21b related to “interlocking” are operated, the angles of the back bottom 70a, the knee bottom 70b, and the leg bottom 70c change in conjunction with each other. The height H1 may change in conjunction.

  As shown in FIG. 2E, a head bottom 70h may be further provided. The head angle can be changed by the operation of the head bottom 70h.

  On the other hand, when the second operation receiving unit 25 receives an operation (for example, when the button 25a or the button 25b is operated), a first memory position (first posture) is formed. This first memory position is one combination of the respective states of the back bottom 70a, the knee bottom 70b, the leg bottom 70c, and the height changing portion 70d. For example, when the second operation receiving unit 25 receives an operation, the back bottom 70a, the knee bottom 70b, the leg bottom 70c, and the height changing unit 70d move according to the stored order. The head bottom 70h may be further controlled by operating the second operation receiving unit 25 (button 25a or button 25b). Also in this case, the order of movement of the head bottom 70h may be stored.

Hereinafter, the storage mode will be described.
FIG. 3 is a flowchart illustrating the storage mode in the control device according to the embodiment.
As shown in FIG. 3, in the initial state, the control device 160 is in a standby state (operation mode). In this state, it is determined whether or not the switching unit (for example, the switch 50) has been operated (step S110). If not operated, the process returns to step S110.

  When the switching unit (switch 50) is operated, the mode shifts to the storage mode (step S120).

  In the storage mode, an initial position is set (step S130). The initial position is an initial position of the movable part 70 in the electric furniture 310. For example, the bottom of the movable part 70 is flat, and the height H1 of the bed surface is the initial height.

  When a plurality of first operation receiving units 20 (for example, operation buttons) are operated, the movable unit 70 (for example, an actuator) of the electric furniture 310 is controlled to operate (step S140). For example, a memory setter (may be a user or a caregiver) operates a plurality of first operation reception units 20 (for example, operation buttons) in a desired order to a desired degree. For example, the bottom part (the head bottom 70h, the back bottom 70a, the knee bottom 70b, and the leg bottom 70c) of the movable part 70 and the height changing part 70d move in a desired order to a desired degree.

  It is determined whether or not the switching unit (for example, switch 50) has been operated (step S150).

  When the switching unit (for example, the switch 50) is not operated, the process returns to step S140. The change of the bottom part of the movable part 70 and the height changing part 70d is continued until a desired state is formed.

  The movements of the bottom portion of the movable unit 70 and the height changing unit 70d in step S140 are stored in, for example, the storage unit (storage device) provided in the control unit 160 or the electric furniture 310. The movement may be stored in a storage device of a server connected to the electric furniture 310 in a wired or wireless manner.

  When a desired movement is obtained in the bottom part of the movable part 70 and the height changing part 70d, the switching part (for example, the switch 50) is operated by the setter. As a result, the storage mode ends (step S160), and an initial standby state (operation mode) is entered. Thereby, the memory setting is completed.

  As described above, in the embodiment, the switching unit (for example, the switch 50) shifts from the operation mode to the storage mode and from the storage mode to the operation mode. In the storage mode, the plurality of first operation receiving units 20 (for example, operation buttons) are actually operated, and the movable unit 70 moves according to the operation. When the memory setting person is a user of the electric furniture 310, the plurality of first operation receiving units 20 in the storage mode in a state where the user is using the electric furniture (sleeping on the electric bed). (For example, an operation button) is operated. Then, the movable unit 70 is moved by a desired degree in a desired order. The order and degree are stored in the storage unit. As a result, it is possible to memorize an appropriate movement that suits the taste.

  In the embodiment, the memory setting person may be a caregiver of the user of the electric furniture 310. In this case, while the user is using the electric furniture (sleeping on the electric bed), the caregiver is watching the user's condition or talking with the user in the memory mode. Meanwhile, the plurality of first operation reception units 20 (for example, operation buttons) are operated. Then, the movable unit 70 is moved by a desired degree in a desired order. The order and degree are stored in the storage unit. As a result, it is possible to memorize an appropriate movement that suits the taste.

FIG. 4A to FIG. 4C are schematic views illustrating states of the electric furniture controlled by the control device according to the embodiment.
These drawings show an example of the operation of the movable unit 70 when the second operation receiving unit 25 receives an operation (for example, when a memory button is operated). The example of this operation corresponds to an example of the movement of the movable unit 70 in the stored order.

  In this example, when the second operation receiving unit 25 receives an operation (for example, when the button 25a is pressed), the leg bottom 70c is slightly raised as shown in FIG.

  As shown in FIG. 4B, thereafter, the back bottom 70a and the leg bottom 70c are raised, the height changing portion 70d is increased, and the bed surface is raised.

  As shown in FIG. 4C, thereafter, the leg bottom 70c is slightly lowered, the height changing portion 70d is further increased, and the bed surface is further raised.

  Thus, in this example, the plurality of bottoms (back bottom 70a, knee bottom 70b, leg bottom 70c, etc.) included in the movable unit 70 and the height changing unit 70d are controlled according to the stored order. The Thereby, one desired memory position is obtained. This memory position is, for example, a position used when the user watches television or the like.

  As described with reference to FIG. 1B, a plurality of buttons (buttons 25 a and buttons 25 b) may be provided as the second operation receiving unit 25. For example, the second position formed by the button 25b may be a posture suitable for, for example, eating, reading, standing up, sleeping, or awakening (however, lying on the bed).

  For example, the user of the electric furniture 310 can obtain a substantially sufficient desired posture only by operating the second operation receiving unit 25 (for example, pressing a memory button). Thereby, the control apparatus and electric furniture which can improve ease of use can be provided.

  In the embodiment, the number of second operation reception units 25 (for example, memory buttons) (that is, the number of stored postures) may be one or two or more.

  As described above, in the embodiment, the second operation receiving unit 25 includes the bottom portion and the height changing unit 70d formed in the storage mode by the plurality of first operation receiving units 20 (for example, operation buttons) in the operation mode. The movement of the bottom part and the height changing part 70d can be controlled according to the order of at least one of the movements. The “order of movement of at least one of the bottom part and the height changing part 70d created in the storage mode by the plurality of first operation receiving units 20 (for example, operation buttons)” is “the plurality of first operation receiving units”. This corresponds to the order of movement of at least one of the bottom part and the height changing part 70d formed and stored in the storage mode by the part 20 (for example, an operation button). The bottom portion includes, for example, at least one of a back bottom 70a, a knee bottom 70b, and a leg bottom 70c. At this time, in the operation mode, the second operation reception unit 25 is formed (stored and formed) in the storage mode by the plurality of first operation reception units 20 (for example, operation buttons), the back bottom 70a, the knee bottom The movement of the bottom part and the height changing part 70d is controlled in accordance with the order of at least two of the movements of the height changing part 70d and at least one of 70b and the leg bottom 70c.

  In the embodiment, for example, a semiconductor storage device, a magnetic storage device, an optical storage device, or the like can be used as the storage unit. This storage unit may be provided in a place different from the place where the electric furniture 310 is provided. For example, a storage device provided in a server that can communicate with the electric furniture 310 (including the control unit 160) may be used as the storage unit. In the embodiment, at least a part of the state of the movable unit 70 stored in the storage unit may be initialized (set to an initial value), for example. For example, in the storage mode, it may be initialized collectively or individually by a predetermined operation (operation of a button or the like).

  FIG. 5 is a schematic perspective view illustrating another electric furniture including the control device according to the embodiment. As shown in FIG. 5, the electric furniture 311 is an electric chair. The electric furniture 311 includes a movable part 70. The movable part 70 includes, for example, a backrest part 70e and a seat surface part 70f. The backrest portion 70e corresponds to a bottom portion whose angle can be changed. The seat surface portion 70f corresponds to the height changing portion. The angle of the seat surface portion 70f may be changeable. The movable unit 70 is controlled by the control device 160 according to the embodiment. The electric furniture 311 can also provide electric furniture that can improve operability.
