FIG. 1A is a perspective view illustrating an electric furniture and a control device. FIG. 1B is a front view illustrating the control device.

As shown in FIG. 1A, the control device 110 according to the embodiment is used together with the electric furniture 310. The electric furniture 310 is, for example, an electric bed. The control device 110 can operate the control of the electric furniture 310. The control device 110 is, for example, a “nurse control panel”. The control device 110 is used by the user's caregiver (including nurses, doctors, etc.). The control device 110 may have various functions such as a lighting on / off function, a nurse or caregiver calling function, and a power on / off function. A hand switch 210 (remote controller) may be provided separately from the control device 110 (for example, the “nurse control panel). The hand switch 210 is mainly a user of the electric furniture 310 (a person who sleeps in an electric bed). Manipulated by.

The electric furniture 310 is used in, for example, a hospital or a nursing care facility. The electric furniture 310 may be used at home or the like.

As shown in FIG. 1A, the electric bed has a movable portion (bottom) 70. The movable portion 70 includes, for example, a back bottom (Back section) 70a, a knee bottom (upper leg section) 70b, a leg bottom (lower leg section) 70c, 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 user's 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 movable portion 70 can change the distance (height) between the floor surface and the bed surface, for example. For the movable portion 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", and "height adjustment" is possible.

The control device 110 includes an operation unit 10. As shown in FIG. 1A, the operation unit 10 is electrically connected to the electric furniture 310 by the cable 15. A control circuit or the like may be provided between the operation unit 10 and the electric furniture 310. As described above, the case where another circuit is provided between them is also included in the state of being electrically connected.

As shown in FIG. 1B, the operation unit 10 includes an operation surface 10a. The operation surface 10a includes an operation reception unit 20.

For example, the operation reception unit 20 includes a touch panel 21 and a plurality of operation buttons 22a and 22b. For example, as shown in FIG. 1B, a plurality of icons IC1 to IC4 for operating the electric furniture 310 are displayed on the touch panel 21.

For example, when the icon IC1 relating to the "head" displayed on the touch panel 21 is selected and the ascending button 22a is pressed, the angle θ1 of the back bottom 70a with respect to the horizontal plane (shown in FIG. 1A) becomes large. For example, when the icon IC1 is selected and the lower button 22b is pressed, the angle θ1 of the back bottom 70a with respect to the horizontal plane becomes smaller. For example, when the icon IC2 related to the “foot” is selected and the ascending button 22a is pressed, the angle θ2 of the knee bottom 70b with respect to the horizontal plane becomes large. For example, when the icon IC2 is selected and the lower button 22b is pressed, the angle θ2 of the knee bottom 70b with respect to the horizontal plane becomes smaller.

For example, when the icon IC3 related to "height" is selected and the ascending button 22a is pressed, the movable portion 70 is raised. For example, when the icon IC3 is selected and the lower button 22b is pressed, the movable portion 70 is lowered. For example, when the icon IC4 related to "interlocking" is selected and the ascending button 22a or the descending button 22b is pressed, the angle θ1 and the angle θ2 change at the same time. 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.

The touch panel 21 can further display information (such as the angle and height of the movable portion 70) regarding the movable portion 70 of the electric furniture 310, for example. The touch panel 21 may display a screen other than the screen for operating the electric furniture 310. For example, the information of the sensor attached to the person sleeping on the electric furniture 310 or the biological information acquired by the sensor may be displayed on the touch panel 21.

The reception of operations by the operation reception unit 20 may include a method such as voice recognition. For example, the electric furniture 310 may be operated (controlled) based on the voice generated by the operator (user) and the voice operation (control).

As shown in FIG. 2A, the control device 110 further includes a hook 30. The hook 30 is connected to the upper part of the operating portion 10 via the rotating portion 45. The hook 30 includes a first portion 31, a second portion 32, and a third portion 33. A rotating portion 45 is provided in the first portion 31. The second portion 32 is connected to the first portion 31. The second portion 32 extends in a direction away from the back surface 10b on the side opposite to the operation surface 10a of the operation unit 10. The second portion 32 is curved, for example. The third portion 33 is connected to the second portion 32 and extends downward from the second portion 32. The second portion 32 is located between the first portion 31 and the third portion 3. The third portion 33 is separated from the back surface 10b.

In this example, the control device 110 further includes a fourth portion 34. The fourth portion 34 is located below the first portion 31.

By the hook 30, the operation unit 10 can be held on, for example, a side rail of the electric furniture 310, a bed grip, or the like. The operation unit 10 is rotatable with respect to the hook 30. By rotating the operation unit 10, for example, the operation surface 10a is oriented in the horizontal direction as shown in FIG. 2A, and the operation surface 10a is upward as shown in FIG. 2B. You can switch between the facing state and the facing state.

The magnitude of friction between the operating portion 10 and the rotating portion 45 is arbitrary. For example, by increasing the friction, it is possible to extend the time from releasing the hand in the state shown in FIG. 2B to the state shown in FIG. 2A. Thereby, for example, the impact when the operation unit 10 comes into contact with the fourth portion 34 can be alleviated. Alternatively, the impact when the operation unit 10 comes into contact with the side rail or the like of the electric bed can be alleviated. For example, by increasing the friction, the operation unit 10 can be stopped in the state shown in FIG. 2B even after the hand is released from the operation unit 10. In this example, the rotating portion 45 includes a screw S. Friction can be increased by providing, for example, a washer or the like between the screw S and the operating portion 10.

FIG. 3A is a rear view illustrating the operation unit. FIG. 3B is a perspective view illustrating the hook and the facing portion. FIG. 4 is a perspective view illustrating another hook.

As shown in FIG. 3A, a cover 11 is provided on a part of the back surface 10b. A part of the cable 15 is covered with the cover 11. The portion of the cable 15 is connected to a connector 14 covered by a cover 11. In FIG. 3A, the above-mentioned part of the connector 14 and the cable 15 covered with the cover 11 is illustrated by a broken line.

As shown in FIG. 3B, the fourth portion 34 has a first surface 41 facing the operation unit 10. The control device 110 further includes a fastener. This fastener fastens the cable 15. In this example, the first fastener 51 is provided on the first surface 41. A second fastener 52 is provided at the lower end of the fourth portion 34. The control device 110 may include the hook 30a shown in FIG. The hook 30a does not include the fourth portion 34, and the first portion 31 is provided with a fastener.

In the following, an example will be described in which the control device 110 includes the hook 30 shown in FIG. 3 (b) and the fastener is provided in the fourth portion 34.

The first fastener 51 fastens the cable 15 pulled out from the operation unit 10. The cable 15 is detachably fastened by, for example, the first fastener 51. In this example, a plurality of first fasteners 51 are provided on the first surface 41.

The first surface 41 includes, for example, a first region 41a and a second region 41b. The second region 41b is provided around the first region 41a. The distance in the front-rear direction between the first region 41a and the third portion 33 is shorter than the distance in the front-rear direction between the second region 41b and the third portion 33. The front-rear direction is, for example, a direction connecting the operation unit 10 and the hook 30. As a result, in the state shown in FIG. 2A, a space for accommodating the cable 15 is formed between the operation unit 10 and the hook 30.

For example, the width of the lower part of the fourth part 34 (the length in the left-right direction) is narrower than the width of the upper part of the fourth part 34. For example, the width of the fourth portion 34 is narrowed downward. The left-right direction is, for example, perpendicular to the front-back direction and follows the horizontal direction. In this example, the second fastener 52 is formed by bending the lower end of the fourth portion 34. The cable 15 is detachably fastened by, for example, a second fastener 52. The cable 15 fastened to the first fastener 51 and the second fastener 52 is pulled out below the fourth portion 34.

As described above, the operation unit 10 of the control device 110 can be held by the electric furniture by the hook 30. The operation unit 10 is rotatable with respect to the hook 30. If the movement of the cable 15 connected to the operation unit 10 is small when the user rotates the operation unit 10, the cable 15 is less likely to be caught by the foot or the like, and the usability of the control device 110 can be improved.

In the control device 110, when the hook 30 is rotatably connected to the upper portion of the operation unit 10, the cable 15 is preferably pulled out from the operation unit 10 in the upper portion of the operation unit 10. This is because the distance that the cable 15 moves when the operation unit 10 is rotated can be shortened as compared with the case where the cable 15 is pulled out from the operation unit 10 in the lower portion of the operation unit 10. As a result, the cable 15 is less likely to be caught by the foot or the like when the operation unit 10 is rotated, and the usability of the control device 110 can be improved.

Alternatively, the control device 110 preferably includes at least one of the first fastener 51 and the second fastener 52. This fastener is fixed to the hook 30. Therefore, by fastening the cable 15 with the fastener, the distance that the cable 15 moves when the operation unit 10 is rotated can be shortened as compared with the case where the fastener is not provided. Thereby, the ease of use of the control device 110 can be improved. When the control device 110 includes a fastener, the cable 15 may be pulled out from a portion other than the upper portion of the operation unit 10. This is because the distance that the cable 15 moves when the operation unit 10 rotates can be shortened by fastening the cable 15 with a fastener.

More preferably, the cable 15 is pulled out of the operating unit 10 at the upper portion of the operating unit 10, and the control device 110 includes at least one of the fasteners. As a result, the distance that the cable can move can be further shortened.

The cable 15 may be fixed to the first surface 41 of the first portion 31 or the fourth portion 34 with an adhesive or the like. Also in this case, the distance that the cable 15 moves when the operation unit 10 is rotated can be shortened.

As shown in FIG. 3A, the connector 14 is preferably provided on the rotation shaft A of the rotation portion 45. As a result, when the operation unit 10 is rotated, the change in the distance between the connector 14 and the fastener can be reduced. For example, the length of the cable 15 required to rotate the operation unit 10 can be shortened.

The control device may include the hook 30b shown in FIG. In the hook 30b, the fourth portion 34 includes a protrusion 42 and an elastic member 43. The protrusion 42 is provided on the first surface 41 of the fourth portion 34. The protrusion 42 is provided in, for example, the first region 41a. The elastic member 43 is provided at the tip of the protrusion 42.

When the operation unit 10 is rotated toward the fourth portion 34, the elastic member 43 comes into contact with the back surface 10b of the operation unit 10. As a result, the impact when the operation unit 10 comes into contact with the fourth portion 34 can be alleviated. By increasing the length of the protrusion in the front-rear direction, the operation surface 10a can be directed upward in a state where the back surface 10b and the elastic member 43 are in contact with each other. As a result, the operation surface 10a becomes easy to see when the back surface 10b and the elastic member 43 are in contact with each other, and the usability of the control device 110 can be improved.

By operating the control of the electric furniture 310 using the control device 110 according to the embodiment, the ease of use of the electric furniture 310 can be improved.

As shown in FIG. 6, the electric furniture 311 is an electric chair. The electric furniture 311 includes a movable portion 70. The movable portion 70 includes, for example, a backrest portion 70e and a seat surface portion 70f. The control device 110 according to the embodiment operates the control of these movable portions 70. As a result, the ease of use of the electric furniture 311 can be improved.

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