The electric bed has a movable portion 70. The movable portion 70 includes, for example, a back bottom 70a, a knee bottom 70b, a leg bottom 70c, a height changing portion 70d, and the like. The angles of the back bottom 70a, the knee bottom 70b, and the leg bottom 70c can be changed. The angle of the back of the user 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 with each other. The height changing portion 70d can change the distance (height) between the floor surface and the bed surface, for example. For these movable portions 70, for example, an actuator or the like is used. By the operation of the movable portion 70, at least one of "back raising", "knee raising", "height adjustment" and the like is possible.

The control device 140 is electrically connected to the movable portion 70. A control circuit may be provided between the control device 140 and the movable portion 70. In this way, even if another circuit is provided between them, it is included in the state of being electrically connected.

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

As shown in FIGS. 1B and 1C, 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, a front surface. 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 a plurality of operation buttons 20 and a display unit 30. The plurality of operation buttons 20 and the display unit 30 are provided on the first surface 10a.

The control device 140 may further include a switch 50. The switch 50 may be, for example, the power button of the control device 140. The switch 50 may be a switch provided in the control device 140 for switching a plurality of modes. 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 surface of the housing of the control device 140. The 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 in 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 the operation mode and the setting mode provided in the control device 140. In the setting mode, the control device 140 can be set by a plurality of operation buttons 20 and the like. In the operation mode, the movable portion 70 of the electric furniture 310 is controlled by operating the plurality of operation buttons 20.

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

In this example, the plurality of operation buttons 20 are an ascending button 21a (first operation button) relating to "interlocking", a descending button 21b (third operation button) relating to "interlocking", and an ascending button 22a relating to "head" (head). 2nd operation button), down button 22b (4th operation button) related to "head", up button 23a (fifth operation button) related to "foot", down button 23b (6th operation button) related to "foot" , The up / down button 24a (7th operation button) regarding "height", the down button 24b (8th operation button) regarding "height", and the like are included.

For example, when the lower button 22b with respect to the "head" is pressed, the angle of the back bottom 70a becomes smaller. For example, when the ascending button 23a relating to the "foot" is pressed, the angles of the knee bottom 70b and the leg bottom 70c are increased. For example, when the lower button 23b relating to the "foot" is pressed, the angles of the knee bottom 70b and the leg bottom 70c become smaller. These angles are, for example, angles from a horizontal plane. For example, when the ascending button 24a relating to "height" is pressed, the bed surface becomes higher. For example, when the lower button 24b relating to "height" is pressed, the bed surface is lowered. For example, when the ascending button 21a relating to "interlocking" is pressed, the "head" and "foot" are interlocked and changed. For example, when the descending button 21b relating to "interlocking" is pressed, the "head" and "foot" are interlocked and changed. These changes are made by the operation of the movable portion 70. For example, the above operation is performed while the operation button is held down. As a result, safe operation can be obtained.

In this example, the plurality of operation buttons 20 further include a button 25a (9th operation button) relating to the first memory position and a button 25b (10th operation button) relating to the second memory position. When the button 25a is pressed, the first memory position is formed. When the button 25b is pressed, a second memory position is formed. The first memory position corresponds to one state of each combination of the back bottom 70a, the knee bottom 70b, the leg bottom 70c, and the height changing portion 70d. The second memory position corresponds to another state of each combination of states of the back bottom 70a, the knee bottom 70b, the leg bottom 70c and the 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 (nurse or the like) of the user of the electric furniture 310.

For the plurality of operation buttons 20, in addition to a switch having mechanical contacts, any input device such as an electrostatic type or an optical type (for example, a touch switch) may be used.

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

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

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

As described above, at least one of the plurality of display units 30 is provided between the two operation buttons 20 arranged in the vertical direction (height direction). The display unit 30 is provided in the area 30R between the plurality of operation buttons 20.

As described above, in the embodiment, the plurality of operation buttons 20 (for example, the first operation button (button 21a) and the second operation button (button 22a)) capable of controlling the operation of the movable portion 70 of the electric furniture 310 are provided. It will be provided. The display unit 30 (for example, the first display unit 31) performs a 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 angle of the back obtained by the operation is displayed on the first display unit 31 according to the change of the “interlocking”. An example of the 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 positions of the first display unit 31 (display unit 30) in the vertical direction (first direction) are 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). It is between the position of. The vertical direction corresponds to, for example, the vertical direction of characters and the like provided on the first surface 10a (for example, the operation surface). Letters and the like include at least one of letters (including numbers), figures and pictograms.

As described above, in the embodiment, the display unit 30 that displays 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 as compared with the reference example in which another display unit is provided.

For example, there is a first reference example in which a display unit is provided on an upper portion of an operation surface (first surface 10a) on which a plurality of operation buttons 20 are provided. In the first reference example, since such a display unit is provided, the length of the control device in the vertical direction becomes long. By shortening the length of the control device in the vertical direction, operability can be further improved.

On the other hand, a second reference example for shortening the distance between the plurality of operation buttons 20 (for example, the distance in the vertical direction) can be considered. In the second reference example, the length of the control device in the vertical direction can be shortened. However, if the distance between the plurality of operation buttons 20 is shortened, it is easy to accidentally press the operation buttons 20 when operating with a finger. As a result, it is difficult to obtain good operability even in the second reference example.

On the other hand, in the control device 140 according to the embodiment, a display unit 30 (first display unit 31 or the like) is provided between the plurality of operation buttons 20. In the embodiment, the display unit 30 is provided in the operation area where the plurality of operation buttons 20 are provided. As a result, the size (length in the vertical direction) 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 value equal to or higher than a certain value in order to suppress erroneous operation. By providing the display unit 30 in the region of a certain distance or more, good operability can be obtained while keeping the size of the control device 140 small.

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

The direction from the second operation button (button 22a) to the fourth operation button (button 22b) is along the lateral 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 positions of the display unit 30 (first display unit 31) in the vertical direction (first direction) are the positions of the third operation button (button 21b) in the vertical direction (first direction) and the positions in the vertical direction (first direction). It is between the position of the fourth operation button (button 22b) in one direction).

For example, the first operation button (button 21a) and the third operation button (button 21b) are descending and ascending, respectively, with respect to one operation (control of "interlocking" angle or height). For example, the second operation button (button 22a) and the fourth operation button (button 22b) are descending and ascending, respectively, with respect to another action (controlling the angle or height of the "head"). 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 down and up buttons for another action form another set of buttons. This other set of buttons is lined up horizontally (second direction). These two sets of buttons are arranged vertically (first direction). A display unit 30 (for example, a first display unit 31) is provided in an area (area 30R) between these two sets of buttons. As a result, the state of control by a set of buttons can be displayed more clearly by the display unit 30.

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

In the embodiment, the first operation button (button 21a) and the second operation button (button 22a) can be interchanged with each other. The third operation button (button 21b) and the fourth operation button (button 22b) can be interchanged with each other. The top and bottom positions of the buttons can be swapped. The left and right (horizontal) positions of the buttons can be swapped.

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.
