Control device 140 is, for example, a hand switch. Controller 140 may have various functions such as turning lights on and off, calling a nurse or caregiver, or turning power on and off.

Electric furniture 310 is used, for example, in hospitals, nursing homes, or homes.

In this example, motorized furniture 310 is a motorized bed. Electric furniture 310 is used, for example, in hospitals, nursing homes, or homes. The electric bed has a movable part 70 . The movable portion 70 includes, for example, a back bottom 70a, knee bottoms 70b, leg bottoms 70c, and a height changing portion 70d. 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 action of the back bottom 70a. The knee angle can be changed by changing the angle between the knee bottom 70b and the leg bottom 70c. These angles may be interlocked and changed. The height changer 70d can change, for example, the distance (height) between the floor surface and the bed surface. For example, an actuator or the like is used for these movable portions 70 . At least one of “raising the back”, “raising the knees”, and “adjusting the height” is possible by the operation of the movable part 70 .

Control device 140 is electrically connected to movable portion 70 described above. A control circuit may be provided between the control device 140 and the movable portion 70 . In this way, the state of being electrically connected also includes the case where another circuit is provided between them.

As shown in FIG. 1( a ), the control device 140 is connected to the electric furniture 310 via the cable 15 . The control device 140 may be connected to the electric furniture 310 by wireless communication. Control device 140 includes operation unit 10 .

As shown in FIGS. 1(b) and 1(c), the control device 140 (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, the 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 140 includes multiple operation buttons 20 and a display section 30 . A plurality of operation buttons 20 and a display section 30 are provided on the first surface 10a.

Controller 140 may further include switch 50 . Switch 50 may be, for example, the power button of controller 140 . The switch 50 may be a switch for switching between a plurality of modes provided in the control device 140 . In this example, the switch 50 is a hardware switch, and the switch 50 is provided on the second surface 10b. The switch 50 may be provided on the side of the housing of the control device 140 . Switch 50 may be, for example, a software controlled switch. In this case, the position where the switch 50 is provided is arbitrary. The switch 50 may be provided inside the housing.

As will be described later, the switch 50 may change at least one function of the plurality of operation buttons 20 . For example, the switch 50 may switch between an operation mode and a setting mode provided in the control device 140 . In the setting mode, it is possible to set the control device 140 using a plurality of operation buttons 20 and the like. In the operation mode, the movable part 70 of the electric furniture 310 is controlled by operating the plurality of operation buttons 20 .

The case of one operation mode will be described below. In this operation mode, the movable portion 70 is controlled by the plurality of operation buttons 20 .

In this example, the plurality of operation buttons 20 include a rise button 21a (first operation button) related to "interlock", a fall button 21b (third operation button) related to "interlock", and a rise button 22a (head) related to "head". 2nd operation button), descent button 22b (fourth operation button) related to "head", up button 23a (fifth operation button) related to "legs", down button 23b (sixth operation button) related to "legs" , an up/down button 24a (seventh operation button) related to "height" and a down button 24b (eighth operation button) related to "height".

For example, when the button 22a for raising the "head" is pressed, the angle of the back bottom 70a increases. For example, when the downward button 22b related to "head" is pressed, the angle of the back bottom 70a is reduced. For example, when the lift button 23a related to "foot" is pressed, the angles of the knee bottom 70b and the leg bottom 70c are increased. For example, when the downward button 23b related to "foot" is pressed, the angles of the knee bottom 70b and the leg bottom 70c are decreased. These angles are, for example, angles from the horizontal plane. For example, when the lift button 24a related to "height" is pressed, the bed surface is raised. For example, when the descent button 24b related to "height" is pressed, the bed surface is lowered. For example, when the rising button 21a related to "interlocking" is pressed, the "head" and "legs" are interlocked and changed. For example, when the descent button 21b related to "interlocking" is pressed, the "head" and "legs" are interlocked and changed. These changes are made by the operation of the movable part 70 . For example, the above operation is performed while the operation button is kept pressed. This provides safe operation.

In this example, the plurality of operation buttons 20 further include a button 25a (ninth operation button) for the first memory position and a button 25b (tenth operation button) for the second memory position. When button 25a is pressed, the first memory position is created. When button 25b is pressed, a second memory position is created. The first memory position corresponds to one combination of the states of the back bottom 70a, knee bottom 70b, leg bottom 70c, and height changing portion 70d. The second memory position corresponds to another combination of the states of the back bottom 70a, knee bottom 70b, leg bottom 70c, and height changing portion 70d. These memory positions may be set by the operator (user) of the control device 140 (or the electric furniture 310). These memory positions may be set by a caregiver (such as a nurse) of the user of electric furniture 310 .

The plurality of operation buttons 20 may be switches having mechanical contacts, or may be electrostatic or optical input devices (for example, touch switches).

The display unit 30 performs display that changes according to the operation of the plurality of operation buttons 20, for example. At least part of the display unit 30 is provided between the plurality of operation buttons 20 . In this example, the display section 30 includes a first display section 31 , a second display section 32 , a third display section 33 and a fourth display section 34 .

For example, at least part of the first display unit 31 is located between the first operation button (button 21a) and the second operation button (button 22a). At least part of the second display section 32 is located between the second operation button (button 22a) and the fifth operation button (button 23a). At least part of the third display section 33 is located between the fifth operation button (button 23a) and the seventh operation button (button 24a). At least part of the fourth display section 34 is located between the seventh operation button (button 24a) and the ninth operation button (button 25a).

In this example, at least part of the first display section 31 is located between the third operation button (button 21b) and the fourth operation button (button 22b). At least part of the second display section 32 is positioned between the fourth operation button (button 22b) and the sixth operation button (button 23b). At least part of the third display section 33 is located between the sixth operation button (button 23b) and the eighth operation button (button 24b). At least part of the fourth display section 34 is located between the eighth operation button (button 24b) and the tenth operation button (button 25b).

Thus, at least one of the plurality of display units 30 is provided between two of the plurality of operation buttons 20 arranged in the vertical direction (height direction). The display section 30 is provided in a region 30R between the plurality of operation buttons 20. As shown in FIG.

As described above, in the embodiment, a plurality of operation buttons 20 (for example, a first operation button (button 21a) and a second operation button (button 22a)) capable of controlling the operation of the movable portion 70 of the electric furniture 310 are be provided. The display unit 30 (for example, the first display unit 31) performs display that changes according to the operation of the first operation button, for example. For example, by operating the first operation button, the angle of the back is increased by "interlocking". At this time, the value corresponding to the back angle obtained by the operation is displayed on the first display unit 31 in accordance with the change of the "interlocking". An example of display will be described later. This value is, for example, a summary value.

Here, the direction (vertical direction) from the first operation button (button 21a) to the second operation button (button 22a) is defined as the first direction. The position of the first display unit 31 (display unit 30) in the vertical direction (first direction) is the position of the first operation button in the vertical direction (first direction) and the position of the second operation button in the vertical direction (first direction). between the position of The vertical direction corresponds to, for example, the vertical direction of characters, etc. provided on the first surface 10a (for example, the operation surface). Characters and the like include at least one of characters (including numbers), graphics, and pictograms.

As described above, in the embodiment, the display unit 30 that performs display according to the operation of the operation button 20 is provided between the plurality of operation buttons 20 . As a result, the size of the control device (for example, the length in the vertical direction of the control device) can be reduced compared to the reference example in which a separate display is provided.

For example, there is a first reference example in which a display section is provided above an operation surface (first surface 10a) on which a plurality of operation buttons 20 are provided. In the first reference example, the vertical length of the control device is increased due to the provision of such a display section. Operability can be further improved by shortening the vertical length of the control device.

On the other hand, a second reference example is conceivable in which the distance (for example, vertical distance) between the plurality of operation buttons 20 is shortened. In the second reference example, the vertical length of the control device can be shortened. However, if the distances between the plurality of operation buttons 20 are shortened, the operation buttons 20 are likely to be pressed by mistake when operated with a finger. As a result, it is difficult to obtain good operability in the second reference example as well.

In contrast, in the control device 140 according to the embodiment, the display section 30 (first display section 31 or the like) is provided between the plurality of operation buttons 20 . In the embodiment, a display section 30 is provided in an operation area in which a plurality of operation buttons 20 are provided. Thereby, the size (longitudinal length) of the control device 140 can be reduced. It is desirable that the distance between the plurality of operation buttons 20 is set to a certain value or more in order to suppress erroneous operation. By providing the display unit 30 in the area at a distance of at least a certain distance, it is possible to obtain good operability while maintaining the size of the control device 140 small.

According to the embodiments, it is possible to provide a control device and electric furniture that can improve operability.

The horizontal direction (second direction) from the first operation button (button 21a) to the third operation button (button 21b) intersects (for example, orthogonally) with the vertical direction (first direction). The direction from the second operation button (button 22a) to the fourth operation button (button 22b) is along the horizontal direction (second direction). The direction from the third operation button (button 21b) to the fourth operation button (button 22b) is along the vertical direction (first direction).

In this example, the position of the display unit 30 (first display unit 31) in the vertical direction (first direction) is the same as the position of the third operation button (button 21b) in the vertical direction (first direction). 1 direction) and the position of the fourth operation button (button 22b).

For example, the first operating button (button 21a) and the third operating button (button 21b) are respectively descent and ascent for one action (“interlocking” angle or height control). For example, the second operating button (button 22a) and the fourth operating button (button 22b) are respectively descent and ascent with respect to another single action (“head” angle or height control). The two buttons, DOWN and UP for one action, form a set of buttons. This set of buttons is arranged in the horizontal direction (second direction). The two buttons, DOWN and UP, for another one action would be another set of buttons. This other set of buttons is arranged horizontally (second direction). These two sets of buttons are arranged vertically (first direction). A display section 30 (for example, a first display section 31) is provided in a region (region 30R) between these two sets of buttons. As a result, the state of control by a set of buttons can be displayed on the display section 30 in a more comprehensible manner.

For example, the display of the display unit 30 (for example, the first display unit 31) changes according to the operation of the third operation button (button 21b), in addition to changing according to the operation of the first operation button (button 21a). may change further. For example, the display of the display unit 30 (for example, the second display unit 32) changes according to the operation of the second operation button (the button 22a), and also changes according to the operation of the fourth operation button (the button 22b). may change further.

In the embodiment, the first operating button (button 21a) and the second operating button (button 22a) are interchangeable. The third operation button (button 21b) and the fourth operation button (button 22b) can be interchanged with each other. The upper and lower positions of the buttons can be interchanged. The left and right (horizontal) positions of the buttons can be interchanged.

For example, the first operation button may be the button 22a and the second operation button may be the button 23a. For example, the first operation button may be the button 23a and the second operation button may be the button 24a. For example, the first operation button may be the button 24a and the second operation button may be the button 25a.

On the other hand, the second operation button (button 22a) can control one of the upward movement and downward movement of another part of the movable part 70 . The fourth operation button (button 22b) can control the other of the upward movement and the downward movement of the other portion of the movable portion 70 . The second operation button and the fourth operation button correspond to another “pair” in the operation of the movable part 70 .

For example, in the plurality of operation buttons 20, another lift button is provided above or below one lift button. By providing at least part of the display unit 30 between these two buttons, good operability can be obtained while maintaining the size of the control device 140 small. For example, in the plurality of operation buttons 20, another descending button is provided above or below one descending button. By providing at least part of the display unit 30 between these two buttons, good operability can be obtained while maintaining the size of the control device 140 small.

As already explained, the movable part 70 includes at least one of the back bottom 70 a , the knee bottom 70 b and the leg bottom 70 c included in the electric furniture 310 . At this time, for example, the first operation button (button 21a) can control one of upward movement and downward movement of at least one of the back bottom 70a, knee bottom 70b, and leg bottom 70c. is. For example, the third operation button (button 21b) can control the other of upward movement and downward movement of at least one of the back bottom 70a, knee bottom 70b, and leg bottom 70c.

For example, upward movement of a part of the movable part 70 includes at least one of increasing the inclination of the frame 70g (see FIG. 1(a)) included in the electric furniture 310 and raising the frame 70g from the floor. But it's okay.

The distance h1 is a distance along the vertical direction (first direction). As a result, erroneous operations of the plurality of operation buttons 20 can be suppressed. The length along the first direction of the first operation button (button 21a) is, for example, 5 mm or more and 20 mm or less.

In the embodiment, the distance h2 (see FIG. 2A) along the vertical direction (first direction) between the first operation button (button 21a) and the display section 30 (first display section 31) is, for example, It is 1 mm or more and 10 mm or less. This enables easy-to-see display. Then, the distance between the plurality of operation buttons 20 (distance h1 described above) can be set to an appropriate value. Good operability and good visibility are obtained.

In the first embodiment described above, the display unit 30 performs display in one operation mode (function) provided for the plurality of operation buttons 20 . The display unit 30 changes according to the operation of at least one of the plurality of operation buttons 20 (for example, the first operation button (button 21a)).

(Second embodiment)
In the second embodiment, functions of a plurality of operation buttons 20 are switched. The changed function is displayed on the display unit 30 . The display unit 30 displays information (for example, function) regarding at least one of the plurality of operation buttons 20 (for example, the first operation button (button 21a)).

FIGS. 3A and 3B are schematic plan views illustrating the control device according to the second embodiment. FIG.
FIG. 3A illustrates, for example, the operation mode (second state ST2). FIG. 3B illustrates the setting mode (first state ST1). These operation modes are switched by, for example, a switch 50 (see FIG. 1(c)). The setting mode (first state ST1) is, for example, a state when the switch 50 is operated and the switch 50 receives an input.

As shown in FIG. 3B, in the first state ST1 (setting mode) of the control device 141, a display is performed on the display section 30 provided between the plurality of operation buttons 20. As shown in FIG. In this example, the display unit 30 includes a call setting display 31a, a short-range wireless communication setting display 31b, an operation prohibition setting display 32a, a speed setting display 32b, a "motion S" setting display 33a, an operation sound setting display 33b, and a "memo position display". ' includes a setting display 34a and a lighting setting display 34b.

As shown in FIG. 3A, in the second state ST2 (operation mode), no display is performed by the display unit 30 described above.

In the operation mode corresponding to the normal usage state, the display by the first display section 30 is not performed. Since unnecessary displays are not displayed, the user feels that the operation buttons 20 are easy to understand. Improved operability.

On the other hand, when the mode is switched to the setting mode, display corresponding to various setting items is performed by the display section 30 .

For example, button 21a located above call setup display 31a functions as an input for call setup in setup mode. For example, by operating the button 21a, the call setting conditions and the like are changed.

For example, the button 21b positioned above the short-range wireless communication setting display 31b functions as an input unit for setting short-range wireless communication in the setting mode. For example, by operating the button 21b, conditions for near field communication settings and the like are changed.

For example, the button 22a located above the operation prohibition setting display 32a functions as an input section for operation prohibition setting in the setting mode. For example, by operating the button 22a, ON/OFF of operation prohibition is changed.

For example, the button 22b located above the speed setting display 32b functions as an input for speed setting in the setting mode. For example, by operating the button 22b, the speed of operation of the movable part 70 and the like are changed.

For example, the button 23a located above the "motion S" setting display 33a functions as an input for the "motion S" setting in the setting mode. "Motion S" is, for example, an input (motion sensor) that detects movements of hands and feet. For example, by operating the button 23a, the condition regarding the setting of "motion S" is changed. For example, a motion sensor may be switched on/off.

For example, the button 23b located above the operation sound setting display 33b functions as an input section for setting the operation sound in the setting mode. For example, the operation sound condition is changed by operating the button 23b. On/off of the operation sound may be switched.

For example, the button 24a located above the "memo position" setting display 34a functions as an input unit for setting the "memo position" (memory posture) in the setting mode. For example, the state (orientation) of the movable portion 70 is stored by operating the button 24a.

For example, the button 24b located above the lighting settings display 34b functions as an input for lighting settings in the settings mode. For example, by operating the button 24b, the conditions related to lighting settings are changed.

Thus, in the first state ST1 (setting mode), the display unit 30 displays information (function in this example) on at least one of the plurality of operation buttons 20 . This display section 30 is provided between one of the plurality of operation buttons 20 and another one of the plurality of operation buttons 20 . In the first state ST1, when either one of the plurality of operation buttons 20 or the other one of the plurality of operation buttons 20 receives an input (when it is operated), the control device 141 performs an operation corresponding to the display on the display unit 30 .

For example, in the first state ST1 (setting mode), the button 21a located above the call setting display 31a is operated, and the button 21a receives an input. At this time, by operating the button 21a, the setting regarding the call is changed corresponding to the display of the call setting display 31a. On the other hand, in the second state ST2 (operation mode), the button 21a functions as an upward button related to "interlocking".

In this way, the operation corresponding to the display on the display unit 30 (for example, call setting) is different from the operation of the plurality of operation buttons 20 in the second state ST2 (operation mode) (lifting related to "interlocking").

For example, in the first state ST1 (setting mode), the button 22b located above the speed setting display 32b is operated, and the button 22b receives an input. At this time, by operating the button 22b, the speed of operation of the movable portion 70 and the like are changed in accordance with the display of the speed setting display 32b.
