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 from the first state to the second state (first operation), and the bottom height is the first. When the value is equal to or smaller than the value, the bottom 70 is further increased (second operation). When the operation reception unit 20 receives the second operation, the angle of the bottom 70 changes toward the first state (third operation). When the operation receiving unit 20 receives the second operation after the second operation, the height of the bottom 70 further decreases (fourth operation).
For example, the drive control unit 120 stores an operation history in the electric bed 310. When the operation reception unit 20 receives the second operation, the drive control unit 120 refers to the history, and executes the fourth operation when the second operation is being executed.

  FIG. 4A to FIG. 4C, FIG. 5A to FIG. 5C, and FIG. 6A to FIG. 6D are schematic views illustrating the operation of the electric bed. FIG. 4D, FIG. 5D, and FIG. 6E are flowcharts illustrating the operation of the electric bed.

  In one example, the first operation is pressing of the ascending button 22a regarding “head”. The second operation is pressing down button 22b related to “head”. For example, in the first state, the back bottom 70a, the knee bottom 70b, and the leg bottom 70c are horizontal.

As shown in FIG. 4D, the operation receiving unit 20 receives the first operation (step S0). The drive control unit 120 determines whether the height of the bottom 70 is equal to or less than a predetermined value V1 (an example of the first value) (step S1). When the height of the bottom 70 is equal to or less than the value V1, the drive control unit 120 drives the height driving unit 72 to raise the bottom 70 (step S2). At this time, the drive control part 120 memorize | stores the height of the bottom 70 before performing step S2, for example.
After execution of step S2 or when the height of the bottom 70 exceeds the value V1 in step S1, the drive control unit 120 drives the back bottom drive unit 71a to change the angle θ1 of the back bottom 70a from the first state to the first state. The state is changed to two states (step S3).
By executing steps S2 and S3, for example, the angle and height of the bottom 70 change from the state shown in FIG. 4A to the state shown in FIG. 4B. For example, the second angle of the back bottom 70a with respect to the horizontal plane in the second state is larger than the first angle of the back bottom 70a with respect to the horizontal plane in the first state.
When the height of the bottom 70 is not more than the value V1 in step S1, step S2 may be executed after step S3. At least a part of step S2 and at least a part of step S3 may be executed simultaneously.

The operation receiving unit 20 receives the second operation (step S4). The drive control unit 120 drives the back bottom drive unit 71a to change the angle θ1 of the back bottom 70a toward the first state (step S5). The drive control unit 120 refers to the stored history and determines whether step S2 has been executed before step S4 (step S6). When step S2 has been executed, the drive control unit 120 drives the height driving unit 72 to decrease the height of the bottom 70 (step S7). In step S7, for example, the drive control unit 120 changes the height of the bottom 70 to the height before step S2 is executed. By executing steps S5 and S7, for example, the height and angle of the bottom 70 change from the state shown in FIG. 4B to the state shown in FIG. 4C.
During the execution of step S5, steps S6 and S7 may be executed. For example, the height of the bottom 70 may be reduced during the change of the angle of the back bottom 70a. Or step S6 and S7 may be performed before step S5.
When step S2 is not executed, for example, the height of the bottom 70 does not change.

  In another example, the first operation is pressing down button 23b related to “leg”. The second operation is pressing of the ascending button 23a regarding “leg”.

As shown in FIG. 5D, the operation receiving unit 20 receives the first operation (step S10). The drive control unit 120 determines whether the height of the bottom 70 is equal to or less than the value V2 (another example of the first value) (step S11). When the height of the bottom 70 is less than or equal to the value V2, the drive control unit 120 drives the height driving unit 72 to raise the bottom 70 (step S12). At this time, the drive control part 120 memorize | stores the height of the bottom 70 before performing step S12, for example.
After the execution of step S12 or when the height of the bottom 70 exceeds the value V2 in step S11, the drive control unit 120 drives the knee bottom drive unit 71b to lower a part of the leg bottom 70c and The angle θ3 of the bottom 70c is changed from the first state to the second state (step S13).
By executing steps S12 and S13, for example, the angle and height of the bottom 70 change from the state shown in FIG. 5A to the state shown in FIG. 5B. For example, the second angle of the leg bottom 70c with respect to the horizontal plane in the second state is larger than the first angle of the leg bottom 70c with respect to the horizontal plane in the first state.
When it is determined in step S11 that the height of the bottom 70 is equal to or less than the value V2, step S12 may be executed after step S13. At least a part of step S12 and at least a part of step S13 may be executed simultaneously.

The operation reception unit 20 receives the second operation (step S14). The drive control unit 120 drives the knee bottom driving unit 71b to change the angle θ3 of the leg bottom 70c toward the first state (step S15). The drive control unit 120 refers to the stored history and determines whether step S12 has been executed before step S14 (step S16). When step S12 has been executed, the drive control unit 120 drives the height driving unit 72 to reduce the height of the bottom 70 (step S17). In step S <b> 17, for example, the drive control unit 120 changes the height of the bottom 70 to the height before step S <b> 12 is executed. By executing steps S15 and S17, for example, the height and angle of the bottom 70 change from the state shown in FIG. 5B to the state shown in FIG. 5C.
During the execution of step S15, steps S16 and S17 may be executed. For example, the height of the bottom 70 may be reduced while the angle of the leg bottom 70c is changing. Or step S16 and S17 may be performed before step S15.
When step S12 is not executed, for example, the height of the bottom 70 does not change.

  The values V1 and V2 are set in advance before using the electric bed 310, for example. The value V2 may be different from the value V1. Each of the values V1 and V2 is set to 10 cm or more and 65 cm or less, for example. That is, the first value is set to, for example, 10 cm or more and 65 cm or less. For example, when the height of the bottom 70 exceeds the first value, even if the first operation is executed, 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 first operation is executed when the height of the bottom 70 is equal to or less than the first value, for example, the above contact may occur. Therefore, when the operation receiving unit 20 receives the first operation, the second operation is executed when the height of the bottom 70 is equal to or less than the first value.

  In the electric bed according to the reference example, after the second operation is executed, when the operation receiving unit 20 receives the second operation, the third operation is executed. In the electric bed according to the reference example, the fourth operation is not executed. That is, the height of the bottom 70 does not change. For this reason, the height of the bottom 70 differs before and after receiving the first operation and the second operation.

  In the electric bed 310 according to the embodiment, when the second operation is performed, the third operation and the fourth operation are performed when the operation receiving unit 20 subsequently receives the second operation. Therefore, the change in the height of the bottom 70 can be reduced before and after receiving the first operation and the second operation. Thereby, the change of the height of the bottom 70 which a user does not intend can be made small, avoiding said contact. For example, the electric bed can be used more easily.

  For example, in the second operation, the height of the bottom 70 increases by the second value. For example, in the fourth operation, the height of the bottom 70 decreases by the second value. Thereby, the height of the bottom 70 before and after acceptance of the first operation and the second operation can be made substantially the same.

  It is preferable that at least a part of the third operation and at least a part of the fourth operation are performed simultaneously. This is because the time during which the bottom 70 is operating can be shortened.

The start of the fourth operation is preferably after the start of the third operation. Alternatively, the start of the fourth operation is preferably simultaneous with the start of the third operation. That is, it is desirable that the height of the bottom 70 decreases after the angle of the bottom 70 starts to change toward the first state.
An operator (user) of the operation unit 10 performs the second operation in an attempt to change the angle of the bottom 70. According to the above operation sequence, the height of the bottom 70 changes after the start of the operation intended by the user. For this reason, the electric bed 310 can be operated more in line with the user's intention.

  Another third operation may be performed between the first operation and the second operation. The height of the bottom 70 may change when the operation receiving unit 20 receives the third operation.

  For example, the first operation is pressing of the ascending button 22a regarding “head”. The second operation is pressing down button 22b related to “head”. The third operation is pressing of the ascending button 24a regarding “height”.

As shown in FIG. 6E, the operation reception unit 20 receives the first operation (step S20). The drive control unit 120 determines whether the height of the bottom 70 is equal to or less than a predetermined value V3 (another example of the first value) (step S21). When the height of the bottom 70 is equal to or less than the value V3, the drive control unit 120 drives the height driving unit 72 to raise the bottom 70 (step S22). For example, in step S22, the height of the bottom 70 is increased by the second value. The drive control unit 120 stores the height of the bottom 70 increased in step S22. By executing steps S22 and S23, for example, the angle and height of the bottom 70 change from the state shown in FIG. 6A to the state shown in FIG. 6B.
The operation reception unit 20 receives the third operation (step S24). The drive control unit 120 drives the height driving unit 72 to increase the height of the bottom 70 by, for example, a third value (step S25). By executing step S25, for example, the height of the bottom 70 changes from the state shown in FIG. 6B to the state shown in FIG. 6C.
The operation reception unit 20 receives the second operation (step S26). The drive control unit 120 drives the back bottom drive unit 71a to change the angle θ1 of the back bottom 70a from the first state to the second state (step S27). The drive control unit 120 refers to the stored history and determines whether step S22 has been executed before step S27 (step S28). When step S22 has been executed, for example, the drive control unit 120 refers to the height of the bottom 70 increased in step S22. Based on this reference result, the drive control unit 120 drives the height drive unit 72 to decrease the height of the bottom 70 by the second value (step S29). By executing steps S27 and S29, for example, the angle and height of the bottom 70 change from the state shown in FIG. 6C to the state shown in FIG. 6D.

  The value V3 is set in advance before using the electric bed 310, for example. The value V3 may be different from the values V1 and V2. The value V3 is set to 10 cm or more and 65 cm or less, for example.

  In this example, the height of the bottom 70 increases by the third value before and after the first operation and the second operation. A change in the height of the bottom 70 controlled by the operator (user) between the first operation and the second operation can be reflected in the height of the bottom 70 after the fourth operation. Therefore, according to this example, the electric bed 310 can be operated more in accordance with the user's intention.

  According to the embodiment, an electric bed that is easier to use can be provided.
