Fig. 1 is an external view of an electric bed 10 in an embodiment of the present invention. The electric bed 10 is an electric bed used in hospitals and homes, and includes a bed bottom 20 for supporting a human body, an adjustment mechanism 30 for adjusting the posture and height of the bed bottom 20, and an operation unit 40 for operating instructions. The adjustment mechanism 30 is given.

The bed bottom 20 is composed of a plurality of rotatable portions which are sequentially connected by a hinge or the like, that is, a back bed bottom 21, a waist bed bottom 22, a knee bed bottom 23, and a foot bed bottom 24.

The adjustment mechanism 30 is a mechanism that adjusts the posture and height of the bed bottom 20 in accordance with an operation command sent from the operation unit 40. The adjustment mechanism 30 is composed of a control circuit, a drive mechanism including an electric actuator that operates under the control of the control circuit, and various types of sensors (not shown) included in the electric bed 10.

As shown in FIG. 2, the operation unit 40 is a hand-held switch that is connected to the adjustment mechanism 30 by wire or wirelessly, and includes a display unit 41, which is configured by a color liquid crystal display module that displays characters, numerical values, symbols, and images; and The panel 42 includes an operation button 43 and a setting button 44.

The operation button 43 includes: a switch button 43a; a power button 43b; a head/back foot linkage up button 43c; a head/back foot linkage down button 43d; a foot up button 43e; a foot down button 43f; a height up button 43g; and a height down button 43h. The switch button 43a is a button for switching the following two modes. One is a "non-linked mode" in which the head/back foot interlocking up button 43c and the head/back foot interlocking down button 43d function only with the back bed bottom 21 as a target. The other is a "linking mode" in which the head/back foot interlocking up button 43c and the head/back foot interlocking down button 43d function as both the back bed bottom 21 and the knee bed bottom 23. The power button 43b is a button for turning on or off the power of the adjustment mechanism 30. The head/back foot linkage raising button 43c causes the back bed bottom 21 to stand up (in the non-linked mode), or raises the back bed bottom 21 and simultaneously raises the joint between the knee bed bottom 23 and the foot bed bottom 24 (linked mode) Time) button. The head/back foot linkage lowering button 43d is used to cause the back bed bottom 21 to fall down (in the non-linked mode), or to cause the back bed bottom 21 to fall down while simultaneously lowering the joint between the knee bed bottom 23 and the foot bed bottom 24 ( Button in linkage mode). The foot rise button 43e is a button for raising the joint between the knee bottom 23 and the foot bed 24. The foot drop button 43f is a button for lowering the joint between the knee bed bottom 23 and the foot bed bottom 24. The height increase button 43g is a button for raising the entire bottom 20 of the bed. The height down button 43h is a button for lowering the entire bottom 20 of the bed.

Fig. 3 is a functional block diagram of the electric bed 10 in the present embodiment. The electric bed 10 includes a bed bottom 20 for supporting a human body, an adjustment mechanism 30 for adjusting the posture and height of the bed bottom 20, and an operation unit 40 for giving an operation command to the adjustment mechanism 30.

The adjustment mechanism 30 adjusts the posture and height of the bed bottom 20 based on the operation command sent from the operation unit 40, and obtains information (sensor information) obtained from various sensors (not shown) of the electric bed 10. It is sent to the operation unit 40.

The operation unit 40 is a hand-held switch that operates the adjustment mechanism 30 by giving an operation command to the adjustment mechanism 30 and receives the sensor information from the adjustment mechanism 30 to present the operator, and includes a display unit 41 and an operation panel. 42; sound output unit 45; and control unit 46.

The display unit 41 displays a display of various settings in the state of the electric bed 10 under the control of the control unit 46, and displays the operation state of the bed bottom 20 by numerical values and graphics, for example.

The operation panel 42 is a collection of buttons including an operation button 43 (a switch button 43a, a power button 43b, a head/back foot linkage up button 43c, a head/back foot linkage down button 43d, a foot up button 43e, a foot down button 43f, The height up button 43g and the height down button 43h) are set to the set button 44. The setting button 44 is a button for performing various settings (specifically, a process of writing setting parameters for determining an operation state to an internal memory or changing a setting parameter in an internal memory), and the various settings are used for changing. The operation of the control unit 46 (that is, the electric bed 10). The various settings include whether or not the output sound and the setting of the button confirmation sound to be described later (operation sound switching), the setting (limitation of the limit value) of the range in which each part of the bed bottom 20 can be operated (the operation position restriction), and the memory of the bed bottom 20 are used. The setting of the position of each part (memory), and the setting of the rise and fall speed of the bed bottom 20, etc.

The sound output unit 45 is a processing unit that outputs sound effects and sounds under the control of the control unit 46, and is composed of a sound synthesis circuit. The content of the sound is as shown in the table below.

Further, in the above table, the operation by the operation button 43 and the setting button 44 ("operation/setting") and the sound content ("sound content") output during the operation are displayed. In the above table, "back rise" means that the head/back foot linkage up button 43c has been pressed in the non-coupling mode. "Back drop" means that the head/back foot linkage down button 43d has been pressed in the non-coupling mode. "Linked back up" means that the head/back foot linkage up button 43c has been pressed in the interlock mode. "Linking back down" means that the head/back foot linkage down button 43d has been pressed in the interlock mode. "Linking switching" refers to switching between the mode (linked mode/non-linked mode) performed by the switch button 43a. "Memory", "Action Part Restriction", "Operation Sound Switching", and "Speed" refer to the respective settings of the setting button 44.

The control unit 46 controls the sound output unit 45 and the processing unit of the adjustment mechanism 30 in accordance with the operation of the operation panel 42. The control unit 46 is composed of a nonvolatile memory such as a ROM storing a control program, a processor such as a CPU that executes a control program, and a volatile memory such as a RAM in a work area executed by the processor.

The control unit 46 performs the following control in terms of its characteristic function.

That is, when the operation button 43 has been pressed and the pressing is continued, the control unit 46 first causes the sound output unit 45 to start the sound output corresponding to the operation button 43 being pressed. Thereafter, the control unit 46 causes the adjustment mechanism 30 to perform an operation corresponding to the operation button 43 by giving an operation command corresponding to the operation button 43 being pressed to the adjustment mechanism 30. Thereby, the sound corresponding to the action is output before the bed bottom 20 is moved. Therefore, even when a person other than the user of the electric bed 10 (the caregiver or the like) performs the operation of the operation unit 40 without properly sounding, the user of the electric bed 10 is suppressed from being shocked by the sudden movement of the bed bottom 20 The situation.

On the other hand, when the pressing of the operation button 43 is released in the sound output, the control unit 46 stops the sound output, and suspends the operation command corresponding to the operation button 43 to the adjustment mechanism 30. Thereby, the operation of the bed bottom 20 can be immediately stopped when the operation button 43 is accidentally pressed or when the bed bottom 20 is made unnecessary or inappropriate. In the present embodiment, when the operation button 43 has been pressed, the sound corresponding to the operation button 43 is first output. Therefore, the operator who hears the sound or the user of the electric bed 10 has a high probability of perceiving this when there is an error in the currently pressed operation button 43 or the pressing is unnecessary. Therefore, with such a cancel function, the action of the bed bottom 20 caused by an erroneous operation or an unnecessary operation can be surely avoided (for example, before execution).

Further, in the operation of the adjustment mechanism 30, when the depression of the operation button 43 is released, the control unit 46 gives a stop command to the adjustment mechanism 30 or does not give an operation command, thereby stopping the operation of the adjustment mechanism 30. Thereby, the action of the bed bottom 20 can be stopped even in the operation of the bed bottom 20.

Further, when the operation button 43 is pressed, the control unit 46 outputs a sound effect corresponding to the operation button 43 being pressed, that is, a button confirmation sound, from the sound output unit 45 before the sound is output. Thereby, the operator knows to what extent the operation button 43 should be pressed by hearing the button confirmation sound, so that the desired operation can be surely performed.

Further, even if the pressing of the operation button 43 is released during the sound output, the control unit 46 regards that the operation button 43 has been pressed for a predetermined time from the time of the release, and is regarded as being processed by the pressing of the operation button 43. That is, the control unit 46 performs sound output and gives an operation command to the adjustment mechanism 30. Therefore, even if the pressing of the operation button 43 is temporarily released in the case where the operator's finger force is insufficient, the adjustment of the adjustment mechanism 30 in which the operation unit 40 is stably performed is realized as if the release is not performed. .

Further, when the pressing of the operation button 43 continues, the control unit 46 gives an operation command to the adjustment mechanism 30 after all the sound outputs have been completed. Thereby, the operator can avoid the bed bottom 20 by releasing the pressing of the operation button 43 in the sound output because the bed bottom 20 is moved after all the sound outputs, so that the erroneous operation is detected, or when an unnecessary operation is detected. Move it up.

Further, when the setting button 44 is pressed and the pressing is continued, the control unit 46 outputs a sound corresponding to the pressing setting button 44 from the sound output unit 45, and performs setting corresponding to the pressing setting button. Thereby, since the sound corresponding to the setting button 44 is output, the operator can use not only the eye (communication with the display unit 41) but also various settings by the ear. Therefore, an accurate setting operation is achieved.

Next, the operation of the electric bed 10 in the present embodiment configured as described above will be described.

Fig. 4 is a flow chart showing the operation of the electric bed 10 in the embodiment.

The control unit 46 determines whether or not the operation button 43 has been pressed (S10), and determines that it has been pressed (YES in S10), and outputs a fixed time (for example, 0.15 second) from the sound output unit 45 corresponding to the pressed operation. The button confirmation sound of the button 43 (S11).

Next, the control unit 46 sound output unit 45 starts the sound output corresponding to the operation button 43 being pressed (S12). Thereafter, the control unit 46 determines whether or not the depression of the operation button 43 has been released during the sound output (S13).

When it is determined that the pressing of the operation button 43 has been canceled (YES in S13), the control unit 46 determines whether or not the operation button 43 has been pressed again within a predetermined time (for example, 0.5 second) from the time of the release (S14). When it is determined that the sound has not been pressed again (NO in S14), the control unit 46 stops the sound output (S15), and does not give the operation command corresponding to the operation button 43 to the adjustment mechanism 30, and returns to the monitoring state of the operation button 43. (S10).

On the other hand, if it is determined that the pressing of the operation button 43 has not been released (NO in S13), and it is determined that the pressing of the operation button 43 has been released, the operation button 43 is re-opened within a predetermined time from the time thereafter. When it has been pressed (YES in S14), the control unit 46 determines whether or not the sound output is completed (S16). As a result of the determination that the sound output has not been completed (NO in S16), the control unit 46 repeats the same processing until the sound output ends (all the sound outputs are completed) (S13 to S15).

When it is determined that the sound output is completed (YES in S16), the control unit 46 sequentially supplies the operation command corresponding to the operation button 43 being pressed to the adjustment mechanism 30, and causes the adjustment mechanism 30 to perform the operation corresponding to the operation button 43. (S17).

Thereafter, the control unit 46 determines whether or not the depression of the operation button 43 has been released during the operation of the adjustment mechanism 30 (i.e., during the operation of the bed bottom 20) (S18). As a result, when it is determined that the pressing of the operation button 43 has been canceled (YES in S18), the control unit 46 determines whether or not the operation button 43 has been pressed again within a predetermined time (for example, 0.5 second) from the time of the release (S19). When it is determined that the vehicle has not been pressed again (NO in S19), the control unit 46 stops the operation of the adjustment mechanism 30 (i.e., the operation of the bed bottom 20) (S20), and returns to the monitoring state of the operation button 43 (S10).

On the other hand, if it is determined that the pressing of the operation button 43 has not been released (NO in S18), and it is determined that the pressing of the operation button 43 has been released, the operation button 43 is re-opened within a predetermined time from the time thereafter. When it has been pressed (YES in S19), the control unit 46 determines whether or not the operation of the adjustment mechanism 30 (i.e., the operation of the bed bottom 20) has reached the operation limit value (S21).

As a result, it is determined that the operation of the adjustment mechanism 30 (that is, the operation of the bed bottom 20) reaches the operation limit value (YES in S21), and the control unit 46 stops the operation of the adjustment mechanism 30 (that is, the operation of the bed bottom 20) ( S20), returning to the monitoring state of the operation button 43 (S10). On the other hand, when it is determined that the operation of the adjustment mechanism 30 (that is, the operation of the bed bottom 20) does not reach the operation limit value (NO in S21), the control unit 46 repeats the same processing (S18 to S20).

Fig. 5A is a timing chart showing an operating state of the electric bed 10 in the embodiment. Here, the timing chart in which the operation button 43 has been pressed and continues until the bed bottom 20 is moved is displayed.

When the operation button 43 has been pressed, a button confirmation sound corresponding to the pressed operation button 43 is output from the sound output unit 45 ("button confirmation sound (0.15 second)" in Fig. 5A). Thereafter, the pressing of the operation button 43 continues, and the sound corresponding to the operation button 43 is output from the sound output unit 45 ("sound output (about 2 seconds)" in Fig. 5A). Further, since the pressing of the operation button 43 continues, the operation corresponding to the bed bottom 20 of the operation button 43 ("bed motion" in Fig. 5A) is performed until the pressing of the operation button 43 is released.

Fig. 5B is another timing chart showing the operating state of the electric bed 10 in the embodiment. Here, it is displayed in the sound output, and the timing chart in the case where the pressing of the operation button 43 has been released is shown.

When the operation button 43 has been pressed, the button confirmation sound corresponding to the pressed operation button 43 is output from the sound output unit 45 ("button confirmation sound (0.15 second)" in Fig. 5B). Thereafter, since the pressing of the operation button 43 continues, the sound output corresponding to the operation button 43 is started next. However, in this case, since the pressing of the operation button 43 is released in the sound output (after 0.5 seconds from the output of the sound), the sound output is stopped at this point of time ("5 seconds of sound output (Fig. 5B) ))), and then the bed bottom 20 does not operate.

Alternatively, the operation shown in FIG. 5C (switching operation mode) can be switched to the operation shown in FIG. 5B instead of the operation shown in FIG. 5B. Fig. 5C is a timing chart showing an operation state of the electric bed 10 in the modification of the embodiment. Here, it is displayed in the sound output, and the timing chart in the case where the pressing of the operation button 43 has been released is shown. In this case, in the sound output (for example, 0.5 seconds after the output of the sound), the pressing of the operation button 43 is released, but the sound output is not stopped, and all the sounds are output (the sound output of FIG. 5C (about 2) second)"). Thereafter, the bed bottom 20 does not operate, and this point is the same as that of Fig. 5B.

Further, in the present embodiment, when the setting button 44 of the operation unit 40 is pressed, the sound corresponding to the setting button 44 being pressed is also output from the sound output unit 45. At this time, the setting process performed by the control unit 46 may be performed after the sound output is completed in the same manner as the "bed bottom operation" shown in FIG. 5A, or may be earlier than the "bed motion" or in parallel with the "bed motion". Conducted.

As described above, according to the electric bed 10 of the present embodiment, the sound corresponding to the operation is output before the bed bottom 20 is moved. Therefore, even if a person other than the user of the electric bed 10 (the caregiver or the like) does not properly sound, when the operation unit 40 operates, the user of the electric bed 10 is prevented from being shocked by the sudden movement of the bed bottom 20. .

Further, in the sound output, when the depression of the operation button 43 is released, the sound output is stopped, and the execution of the adjustment mechanism 30 is also suspended. Thereby, when the operation button 43 is erroneously pressed, or when it is found that the operation of the bed bottom 20 is unnecessary or inappropriate, the operation of the bed bottom 20 can be immediately stopped. That is, the operator who hears the sound corresponding to the operation button 43, or the user of the electric bed 10, has a high probability of perceiving this when the currently operated operation button 43 is incorrect or the pressing is unnecessary. point. Therefore, with such a cancel function, the action of the bed bottom 20 due to erroneous operation or unnecessary operation can be surely avoided.

Further, when the operation button 43 has been pressed, a button confirmation sound is output before the sound is output. Thereby, the operator knows to what extent the operation button 43 should be pressed by hearing the button confirmation sound, so that the desired operation can be surely performed.

Further, in the sound output, even if the pressing of the operation button 43 is released, when the operation button 43 has been pressed for a predetermined time from the time of the release, it is considered that the pressing of the operation button 43 has not been released. Therefore, even if the pressing of the operation button 43 is temporarily released in the case where the operator's finger force is insufficient, the adjustment of the adjustment mechanism 30 in which the operation unit 40 is stably performed is realized as if the release is not performed. .

Further, the bed bottom 20 is moved after outputting all the sounds corresponding to the operation buttons 43. Thereby, when the erroneous operation is detected, or when an unnecessary operation is detected, the bed bottom 20 is prevented from being operated by the release of the release operation button 43 during the sound output.

Although the electric bed of the present invention has been described above based on the embodiment, the present invention is not limited to the embodiment. Various modifications that can be considered by those skilled in the art can be applied to the present embodiment without departing from the spirit of the invention, and other embodiments in which some of the components of the embodiment and the modifications are arbitrarily combined are included in the present invention. Within the scope of the invention.

For example, the content, type, pitch, sound quality, mood, intonation, volume, and the like of the sound output from the sound output unit 45 by the setting button 44 of the operation unit 40 may be changed. At this time, the current setting content (for example, sound quality) may be displayed on the display unit 41 as shown in the display example of the display unit 41 shown in FIG. 6 .

Further, in the above embodiment, the operation button 43 is disposed on the front surface of the operation unit 40, and the setting button 44 is disposed on the side surface of the operation unit 40, but the arrangement is not limited thereto. The setting button 44 may be disposed on the front surface or the back surface of the operation unit 40, or may be used together with the operation button 43, or may not be provided in the operation unit 40.

Further, in the above-described embodiment, the bed bottom 20 is operated after all the sound outputs have been completed. However, as shown in the timing chart of Fig. 7, the operation of the bed bottom 20 may be started before the completion of all the sound output. In such a situation, even if the pressing of the operation button 43 is released during the period from the start of the sound output to the start of the operation of the bed bottom 20, the sound output is stopped, and the bed bottom 20 can be prevented from operating. Further, in a period in which the sound output is performed in parallel with the operation of the bed bottom 20, when the pressing of the operation button 43 is released, both the sound output and the operation of the bed bottom 20 are stopped.

Further, in the above-described embodiment, the sound output is stopped in the middle, and after the pressing of the operation button 43 is released, the same operation button 43 is not pressed again in a predetermined time (S13 to S15 in Fig. 4), but Not limited to this situation. Fig. 8 is a flow chart showing the operation of the electric bed in a modification of the embodiment of the present invention. The same steps as in FIG. 4 are denoted by the same reference numerals as in FIG. 4. Here, steps S30 to S35 are different from FIG. 4. In this modification, after the depression of the operation button 43 has been released (S13), it is determined whether or not the operation button 43 has been pressed again (S30), and as a result, it is determined that the operation button 43 has not been pressed (NO in S30). ), all the sounds are output (S31). On the other hand, when the operation button 43 is pressed again (YES in S30), the pressing is performed within a predetermined predetermined time (for example, 0.5 second) after the release (S32 in the case of S28), and all the outputs are output. The sound (S31). On the other hand, when the pressing is not performed for a predetermined period of time (NO in S32), it is determined whether or not the pressed operation button 43 is the same as the operation button 43 that is released (S33). As a result, it is determined that the pressed operation button 43 is different from the operation button 43 that has been released (NO in S33), the sound output is stopped (stopped halfway), and the new operation button 43 corresponding to the depression is pressed. Action (S34). On the other hand, when the operation button 43 that has been pressed is the same as the operation button 43 that is released (Yes in S33), the sound output is stopped (stopped halfway), and the operation corresponding to the same operation button 43 that has been pressed is performed ( S35). Thus, when the operation button 43 is pressed again after the pressing of the operation button 43 has been released for a predetermined period of time or longer, the sound output can be stopped. At this time, in addition to the stop of the sound output, an action corresponding to the newly pressed operation button 43 is also performed.

Further, in the sound output, the "sound content" shown in the above table can be output once, and the sound output can be continued for a predetermined fixed time (for example, 2 seconds) (the "sound content" can be repeated). By continuing the sound output for a fixed period of time, it is not limited to the type of the operation button 43 (that is, "the content of the sound"), and the sound of a fixed time is always output. Therefore, the user of the electric bed can always prepare for the action of the bottom of the bed at a fixed time until the bottom of the bed is moved.

Further, in the above-described embodiment, the operation unit 40 is a portable controller such as a hand-held switch, but may be a fixed-type controller, or may be configured by both a portable controller and a fixed-type controller.

Further, in the above-described embodiment, the control unit 46 included in the operation unit 40 has a function as an independent controller, but the present invention is not limited to this embodiment. The control unit 46 may be a slave controller and operates under a master controller (for example, a control circuit included in the adjustment mechanism 30) provided outside the operation unit 40. For example, when the operation button 43 is pressed, the control unit 46 of the operation unit 40 may notify the host controller provided outside the control information of the operation button 43 and receive the display data from the controller and display it on the display unit. Display unit 41. In other words, the control unit 46 may be a circuit that has a simple function of inputting and outputting (information transmission) between the display unit 41, the operation panel 42, and the external sound controller 45. Thereby, the operation of the electric bed 10 can be changed by changing the control function of the external controller.
