Embodiments of the present invention will be described below with reference to 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.

  As shown in FIG. 1A, the electric bed 310 according to the embodiment includes an operation unit 10 and a bottom 70. The operation unit 10 can operate the control of the bottom 70. The operation unit 10 is, for example, a remote controller for the electric bed 310. The operation unit 10 is, for example, a hand switch. The operation unit 10 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 bed 310 is used in, for example, a hospital, a nursing facility, or a home.

  The bottom 70 includes, for example, a back bottom 70a, a knee leg (upper leg section) 70b, and a leg bottom (lower leg section) 70c. In the back bottom 70a, the knee bottom 70b, and the leg bottom 70c, the mutual angle can be changed.

  For example, as illustrated in FIG. 2, the bottom 70 includes a back bottom drive unit 71 a, a knee bottom drive unit 71 b, and a height drive unit 72. For example, each of the back bottom drive unit 71a, the knee bottom drive unit 71b, and the height drive unit 72 includes an actuator. By driving the back bottom drive unit 71a, the back bottom 70a operates, and the back angle of the user P (person who sleeps on an electric bed) can be changed. By driving the knee bottom drive unit 71b, the knee bottom 70b and the leg bottom 70c operate, and the angle between these bottoms can be changed. Thereby, the angle of the user's P knee can be changed. The angle between the bottoms may change in conjunction. By driving the height driving unit 72, the height of the bottom 70 (the distance between the floor surface and the bed surface) can be changed.

  The electric bed 310 includes a drive control unit 120. The drive control unit 120 includes a bottom control unit 121 and a height control unit 122. The back bottom drive unit 71 a and the knee bottom drive unit 71 b are electrically connected to the bottom control unit 121. The operations of the back bottom drive unit 71 a and the knee bottom drive unit 71 b are controlled based on a signal transmitted from the bottom control unit 121. The height driving unit 72 is electrically connected to the height control unit 122. The operation of the height driving unit 72 is controlled based on a signal transmitted from the height control unit 122.

  The operation unit 10 is electrically connected to the drive control unit 120. For example, the operation unit 10 is connected to the drive control unit 120 illustrated in FIG. 2 by the cable 15 illustrated in FIG. A control circuit may be provided between the operation unit 10 and the drive control unit 120. In this manner, a case where another circuit is provided in between is also included in the state of being electrically connected. The operation unit 10 may be connected to the drive control unit 120 by wireless communication means.

  As shown in FIG. 1B, the operation unit 10 includes an operation surface 10a. The operation surface 10 a includes an operation reception unit 20. The operation reception unit 20 can receive a control operation for the bottom 70 of the electric bed 310. Control operation is performed by the operator (user) of the operation part 10, for example.

  For example, the operation reception unit 20 includes a plurality of operation buttons. For example, when the ascending button 22a regarding the “head” is pressed, the angle θ1 of the back bottom 70a with respect to the horizontal plane increases as shown in FIG. In this example, the entire angle of the bottom 70 and the angle between the knee bottom 70b and the leg bottom 70c also change in conjunction with each other. For example, when the lowering button 22b related to “head” is pressed, the angle θ1 of the back bottom 70a with respect to the horizontal plane decreases. For example, in a state where the knee bottom 70b and the leg bottom 70c are horizontal, when the ascending button 23a relating to the “foot” is pressed, the angle θ2 of the knee bottom 70b with respect to the horizontal plane increases as shown in FIG. . For example, in a state where the angle θ2 is greater than 0 degrees, when the descending button 23b related to “foot” is pressed, the angle θ2 of the knee bottom 70b with respect to the horizontal plane is decreased. For example, in a state where the knee bottom 70b and the leg bottom 70c are horizontal, when the lowering button 23b related to the “foot” is pressed, a part of the leg bottom 70c is lowered as shown in FIG. The angle θ3 of the leg bottom 70c with respect to is increased.

  For example, when the ascending button 24a regarding “height” is pressed, the bottom 70 becomes higher. For example, when the lowering button 24b regarding “height” is pressed, the bottom 70 is lowered. For example, when the ascending button 21a or the descending button 21b related to “interlocking” is pressed, the angle θ1 and the angle θ2 change simultaneously. These changes are performed by the operation of the bottom 70.

  For example, the above operation is performed while the operation button is kept pressed. Thereby, a safe operation is obtained.

  The operation receiving unit 20 may be any input device such as an electrostatic type or an optical type (for example, a touch switch) in addition to a switch having a mechanical contact. In the embodiment, the operation reception in the operation reception unit 20 may include a method such as voice recognition. For example, a voice generated by an operator (for example, a user of the electric bed 310) may be recognized, and the operation (control) of the electric bed 310 may be performed based on the operation (control) by voice.

  As shown in FIG. 1B, a display area 28 may be provided on the operation surface 10a. The display area 28 can display, for example, information related to the bottom 70 of the electric bed 310 (such as the angle and height of the bottom 70). The display area 28 may display information on the function or operation state of the operation reception unit 20.

  As shown in FIG. 1B, a hook 30 may be provided on the operation unit 10. With the hook 30, the operation unit 10 can be held on, for example, a side rail of the electric bed 310 or a bed grip.

  In the electric bed 310, when the operation reception unit 20 of the operation unit 10 receives the first operation, the angle of the bottom 70 changes. When the height of the bottom is equal to or lower than the first value, the electric bed 310 raises the bottom 70 at least partly while the angle of the bottom 70 is changing.

  FIG. 4A, FIG. 4B, FIG. 5A, and FIG. 5B are schematic views illustrating the operation of the electric bed. FIG. 4C and FIG. 5C are flowcharts illustrating the operation of the electric bed.

  In one example, the first operation is pressing of the ascending button 22a regarding “head”. As shown in FIG. 4C, the operation receiving unit 20 receives the first operation (step S1). The drive control unit 120 determines whether the height of the bottom 70 is equal to or less than the first value (step S2). When the height of the bottom 70 is equal to or less than the first value, the drive control unit 120 drives the back bottom drive unit 71a to increase the angle θ1 of the back bottom 70a and while the angle θ1 is large. At least in part, the height driving unit 72 is driven to raise the bottom 70 (step S3). By this step S3, for example, the bottom 70 moves from the state shown in FIG. 4A to the state shown in FIG. When the height of the bottom 70 exceeds the first value, the drive control unit 120 drives the back bottom drive unit 71a to increase the angle θ1 of the back bottom 70a (step S4).

  In another example, the first operation is pressing of the lowering button 23b regarding the “leg” in a state where the knee bottom 70b and the leg bottom 70c are horizontal. As shown in FIG. 5C, the operation receiving unit 20 receives the first operation (step S11). The drive control unit 120 determines whether the height of the bottom 70 is equal to or less than the first value (step S12). When the height of the bottom 70 is equal to or smaller than the first value, the drive control unit 120 drives the knee bottom driving unit 71b to increase the angle θ3 of the leg bottom 70c, and while the angle θ3 is increased. At least in part, the height driving unit 72 is driven to raise the bottom 70 (step S13). By this step S13, for example, the bottom 70 moves from the state shown in FIG. 5A to the state shown in FIG. When the height of the bottom 70 exceeds the first value, the drive control unit 120 drives the knee bottom driving unit 71b to increase the angle θ3 of the leg bottom 70c (step S14).

  For example, the first value is set in advance before using the electric bed 310. For example, when the height of the bottom 70 exceeds the first value, when the angle of the bottom 70 changes, contact between the components included in the electric bed 310 or between the components included in the electric bed 310 and the floor surface does not occur. . The first value is set to, for example, 10 cm or more and 65 cm or less.

  If the angle of the bottom 70 changes when the height of the bottom 70 is equal to or less than the first value, for example, the above contact may occur. In order to avoid this contact, an electric bed according to the following reference example can be considered. In the electric bed according to this reference example, when the height of the bottom 70 is equal to or less than the first value, the angle of the bottom 70 changes after the height of the bottom 70 becomes higher than the first value. That is, the operation of changing the angle of the bottom 70 intended by the user is performed after raising the bottom 70.

  On the other hand, in the electric bed 310 according to the present embodiment, when the operation receiving unit 20 receives the first operation, the angle of the bottom 70 changes when the height of the bottom 70 is equal to or less than the first value. The bottom 70 is raised at least partly during the period. Therefore, compared with the electric bed according to the reference example, the operation of changing the angle of the bottom 70 intended by the user is performed faster. According to this embodiment, it becomes possible to operate the electric bed 310 more in line with the user's intention.

  The horizontal axis of FIGS. 6A to 6C represents the time T. FIG. 6A to FIG. 6C schematically show a period in which the height H of the bottom 70 and the angle A of the bottom 70 are changing.

  For example, in the electric bed 310, as shown in FIG. 6A, the angle of the bottom 70 starts to change after the bottom 70 starts to rise. Thereby, said contact at the time of changing the angle of the bottom 70 can be avoided more reliably.

  In the electric bed 310, as shown in FIG. 6B, the bottom 70 may begin to rise after the angle of the bottom 70 starts to change. Thereby, the operation intended by the user is performed more quickly. It becomes possible to operate the electric bed 310 more in line with the user's intention.

  In the electric bed 310, as shown in FIG. 6C, the bottom 70 may begin to rise at the same time as the angle of the bottom 70 begins to change. Thereby, it becomes possible to operate the electric bed 310 more in line with the user's intention while more reliably avoiding the above contact when the angle of the bottom 70 is changed.

  According to the embodiment, it is possible to provide an electric bed that can operate more in line with the user's intention.
