Description

[Technical Field]

[0001] The present invention relates to a bed in which a movable part can be driven by an operating part. [Background technology]

[0002] BACKGROUND ART Reclining beds, which can raise the back and thighs of a reclining person and adjust the height, have been widely used in the past, mainly in hospitals and nursing care facilities.

[0003] In conventional reclining beds, a back support base that supports the back of a person lying down and a thigh support base that supports the thighs of a person lying down are arranged so that they can be raised and lowered relative to the support base, and movable parts are provided between the support base and the back support base or thigh support base.

[0004] Then, the user (such as a person lying down or a caregiver) operates the operation button on the operating unit to drive the movable unit and raise or lower the back support base and thigh support base relative to the support base, so that the inclination angle of the back support base and thigh support base becomes the desired angle (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-141437 Summary of the Invention [Problem to be solved by the invention]

[0006] In the above-mentioned conventional bed, each movable part such as the back support and thigh support can be independently driven by the operating unit, so that the back support and thigh support can be individually raised or lowered to the desired inclination angle, and also, multiple movable parts can be driven in conjunction with the operating unit, so that the back support and the thigh support can be simultaneously raised or lowered to the desired inclination angle.

[0007] However, in conventional beds, each moving part operates according to a predetermined setting (set in advance by the bed manufacturer), which may not necessarily be perceived as a comfortable operation for the user. [Means for solving the problem]

[0008] Therefore, in the present invention according to claim 1, in a bed in which the movable part can be driven by an operation part, when a plurality of operation buttons on the operation part are operated simultaneously for a predetermined period of time, the setting of the bed can be changed in accordance with the plurality of operation buttons operated simultaneously. The speed of the moving part is changed only while multiple operation buttons are being operated simultaneously. I decided to do it.

[0009] In addition, in the present invention according to claim 2, In the present invention according to claim 1, The operation unit has one or more types of operation buttons, including one or more first operation buttons for driving multiple movable parts in conjunction with each other, one or more second operation buttons for driving each movable part independently, and one or more third operation buttons for changing the operation that the multiple movable parts perform in conjunction with each other when the first operation button is operated, and when multiple operation buttons of the same type or different types are operated simultaneously for a predetermined period of time in succession, the bed settings can be changed according to the multiple operation buttons operated simultaneously. [Effects of the Invention]

[0011] The present invention provides the following effects.

[0012] In other words, in the present invention, in a bed in which the movable part can be driven by an operating part, when multiple operating buttons on the operating part are operated simultaneously for a predetermined period of time in succession, the bed settings can be changed in accordance with the multiple operating buttons operated simultaneously, so that the bed settings can be easily changed and operation can be made comfortable for the user.

[0013] In particular, the operation unit has one or more types of operation buttons, including one or more first operation buttons for driving multiple movable parts in conjunction with each other, one or more second operation buttons for driving each movable part independently, and one or more third operation buttons for changing the operating mode of the multiple movable parts when the first operation button is operated.When multiple operation buttons of the same type or different types are operated simultaneously for a predetermined period of time, the bed settings can be changed according to the multiple operation buttons operated simultaneously, so that the bed settings can be easily changed using existing operation buttons.

[0014] In addition, since the speed of the drive of the movable part is changed only while multiple operation buttons are being operated simultaneously, the setting of the drive of the movable part can be easily changed only while the user desires. [Brief explanation of the drawings]

[0015] [Figure 1] 1 is an explanatory diagram showing a bed according to the present invention. [Figure 2] FIG. [Figure 3] FIG. 4 is an explanatory diagram showing the movable states of a plurality of movable parts. [Figure 4] FIG. 4 is an explanatory diagram showing a movable state of a movable part. DETAILED DESCRIPTION OF THE INVENTION

[0016] Hereinafter, a specific configuration of the bed according to the present invention will be described with reference to the drawings.

[0017] As shown in Fig. 1, bed 1 has support table 3 provided on top of base 2 so that it can be raised and lowered, and a receiving table 4 for supporting the body of a person lying down provided on top of support table 3. For convenience, the foot side of a person lying down on bed 1 will be described as the front side, and the head side as the rear side.

[0018] The support base 4 is composed of a buttocks support base 5 that mainly receives the weight of the buttocks of the reclining person (supporting the buttocks of the reclining person from below), an upper body support base 6 that mainly receives the weight of the upper body (above the buttocks) of the reclining person (supporting the upper body of the reclining person from below), and a lower body support base 7 that mainly receives the weight of the lower body (below the buttocks) of the reclining person (supporting the lower body of the reclining person from below).

[0019] The buttocks support 5 is fixed horizontally in the approximate center of the support base 3. The buttocks support 5 may be rotatable relative to the support base 3.

[0020] The upper body support 6 is provided so as to be able to rise and fall relative to the support 3 and the buttocks support 5 by pivoting its front end to the rear side of the support 3 (rearward of the buttocks support 5) so as to be able to rotate up and down.

[0021] This upper body support 6 is divided into a back support 8 that mainly receives the weight of the back (spine) below the shoulders (scapulae) of the reclining person (supporting the back (spine) below the shoulders (scapulae) of the reclining person from below), and a shoulder support 9 that mainly receives the weight of the shoulders (scapulae) and above the shoulders and head of the reclining person (supporting the shoulders (scapulae) and above the shoulders and head of the reclining person from below). Note that the shoulder support 9 not only supports the head of the reclining person but also the shoulders (scapulae), but is not limited to this and may be configured as a headrest that only supports the head of the reclining person.

[0022] The upper body support 6 has the front end of the back support 8 pivotally attached to the rear of the buttocks support 5 of the support base 3 so as to be vertically rotatable. This allows the back support 8 to be raised and lowered relative to the support base 3 and the buttocks support 5. The upper body support 6 also has the front end of the shoulder support 9 pivotally attached to the rear end of the back support 8 so as to be vertically rotatable. This allows the shoulder support 9 to be raised and lowered together with the back support 8 relative to the support base 3 and the buttocks support 5, and can also be raised and lowered relative to the back support 8.

[0023] The lower body support 7 is pivotally attached at its rear end to the front side of the support 3 (forward of the buttocks support 5) so that it can be raised and lowered relative to the support 3 and buttocks support 5.

[0024] This lower body support 7 is divided into a thigh support 10 that mainly receives the weight of the thighs of a reclining person (supports the thighs of a reclining person from below), and a lower leg support 11 that mainly receives the weight of the lower legs of a reclining person (supports the lower legs of a reclining person from below).

[0025] The rear end of the thigh support 10 of the lower body support 7 is pivotally attached to the support base 3 in front of the buttocks support 5 so that it can rotate up and down. This allows the thigh support 10 to be raised and lowered relative to the support base 3 and the buttocks support 5. The rear end of the crus support 11 of the lower body support 7 is pivotally attached to the front end of the thigh support 10 so that it can rotate up and down. This allows the crus support 11 to be raised and lowered together with the thigh support 10 relative to the support base 3 and the buttocks support 5, and is also able to be raised and lowered (flexible) relative to the thigh support 10. The rear end of the crus support 11 moves together with the front end of the thigh support 10, and the front end moves along the top surface of the support base 3.

[0026] Movable units 18, 19, and 20, each consisting of actuators 12, 13, and 14 and interlocking mechanisms 15, 16, and 17, are connected to the back support 8, shoulder support 9, and thigh support 10, respectively, for independently raising and lowering them relative to the support base 3. Each actuator 12, 13, and 14 is composed of a motor 21, 22, and 23, and a rod 24, 25, and 26 that can be moved forward and backward by the motor 21, 22, and 23. Each interlocking mechanism 15, 16, and 17 is configured so that the back support 8, shoulder support 9, and thigh support 10 rotates up and down by the forward and backward movement of the rod 24, 25, and 26 of each actuator 12, 13, and 14.

[0027] A movable part 29 consisting of an actuator 27 and an interlocking mechanism 28 for raising and lowering the support base 3, which supports the back support 8, shoulder support 9, and thigh support 10, is connected to the support base 3. The actuator 27 is composed of a motor 30 and a rod 31 that can be moved forward and backward by the motor 30. The interlocking mechanism 28 is configured so that the support base 3 is raised and lowered up and down by the forward and backward movement of the rod 31 of the actuator 27.

[0028] The movable parts 18, 19, 20, and 29 (actuators 12, 13, 14, and 27) are connected to a control unit C, and the motors 21, 22, 23, and 30 are controlled and driven in accordance with a program stored in the control unit C.

[0029] Sensors 32 to 35 that detect extension of the rods 24, 25, 26, and 31 of the actuators 12, 13, 14, and 27 are connected to the control unit C. The sensors 32 to 35 may be built into the actuators 12, 13, 14, and 27.

[0030] The control unit C is also connected to an operation unit 36 ​​and various sensors (for example, sensors that detect the standing angles of the pedestals 8, 9, and 10 and the height of the support base 3). The standing angles of the pedestals 8, 9, and 10 and the height of the support base 3 may be calculated from the extensions of the rods 24, 25, 26, and 31 of the actuators 12, 13, 14, and 27.

[0031] As shown in FIG. 2, the operation unit 36 ​​has a first operation button 37 for driving the multiple movable parts 18, 19, and 20 in conjunction with each other, a second operation button 38 for driving each movable part 18, 19, 20, and 29 independently, and a third operation button 39 for changing the operating mode of the multiple movable parts 18, 19, and 20 when the first operation button 37 is operated, all provided on the same surface (here, the front).

[0032] The operation unit 36 ​​is provided with a liquid crystal display screen 40 on the same surface as the first to third operation buttons 37 to 39, and is also provided with a sound generator 41 and a vibration generator 42 inside. Here, the third operation button 39 is different in size from the other first and second operation buttons 37, 38, but this is not limited to this and the color or shape may be different. The sound generator 41 is not limited to one that generates a sound such as a beep, but may also be one that generates voice.

[0033] Here, the first operation button 37 includes an operation button 43 on the upright side for raising the back support 8 and raising the shoulder support 9 and thigh support 10, thereby causing the back support 8, shoulder support 9, and thigh support 10 to operate in unison (operate in unison), and an operation button 44 on the lowering side for lowering the back support 8 and raising the shoulder support 9 and thigh support 10, thereby causing the back support 8, shoulder support 9, and thigh support 10 to operate in unison (operate in unison).

[0034] In addition, the second operation buttons 38 include an operation button 45 for raising the support base 3 (receiving base 4), an operation button 46 for lowering the support base 3 (receiving base 4), an operation button 47 for raising the back support base 8 alone, an operation button 48 for lowering the back support base 8 alone, an operation button 49 for raising the shoulder support base 9 alone, an operation button 50 for lowering the shoulder support base 9 alone, an operation button 51 for raising the thigh support base 10 alone, and an operation button 52 for lowering the thigh support base 10 alone.

[0035] In addition, the third operation button 39 includes an operation button 53 for switching to a linked mode in which the multiple movable parts 18, 19, 20, 29 are linked together with a preset operation (an operation preset by the bed manufacturer before shipping the bed) when the first operation button 37 is operated, and an operation button 54 for switching to a memory mode in which the multiple movable parts 18, 19, 20, 29 are linked together with an operation newly added and set by the user (an operation set after shipping the bed) that is different from the preset operation (an operation preset by the bed manufacturer before shipping the bed) when the first operation button 37 is operated.

[0036] For example, when operation button 53 is operated to set the operation mode to the linked mode, operating first operation button 37 causes back support 8 to reach inclination angle A4 at time t2, maintain that state until time t3, and then be driven and controlled to reach inclination angle A5 at time t4, as shown by the solid lines in Figure 3; shoulder support 9 to reach inclination angle A1 at time t1, maintain that state until time t4; and thigh support 10 to reach inclination angle A3 at time t1, maintain inclination angle A0 at time t2, maintain that state until time t3, and then be driven and controlled to reach inclination angle A2 at time t4.

[0037] When the operation mode is changed to memory mode by operating operation button 54, operating first operation button 37 causes back support 8 to reach tilt angle A6 at time t2, maintain that state until time t3, and then be driven and controlled to reach tilt angle A7 at time t4, as shown by the dashed line in Figure 3, and shoulder support 9 and thigh support 10 are driven and controlled in the same way as in the linked mode.

[0038] Here, we have explained the case where only the operation of the back support 8 is newly added and set by the user, but this is not limited to this, and the shoulder support 9 and thigh support 10 can also be newly added and set by the user in the same way.

[0039] In addition, here, a multi-memory mode is used in which the multiple movable parts 18, 19, and 20 are operated to sequentially pass through multiple states (tilt angles A6 and A7) newly set by the user, but this is not limited to this, and a single-memory mode may be used in which the multiple movable parts 18, 19, and 20 are operated to reach one state newly set by the user, and the operation button 54 may be operated to switch between the multi-memory mode and the single-memory mode.

[0040] For example, in the single memory mode, as shown in FIG. 4(a), when the operation button 47 for raising the back support 8 alone is operated, the back support 8 is controlled and driven to reach the pre-stored tilt angle A8, and as shown in FIG. 4(b), when the operation button 46 for lowering the support base 3 is operated, the support base 3 is controlled and driven to reach the pre-stored height H2 from the current height H1.

[0041] When any one of the operation buttons 43-54 is operated alone, the operation unit 36 ​​will drive and control the movable parts 18, 19, 20, 29 in accordance with the operated operation button 43-54. However, when multiple operation buttons 43-54 of the operation unit 36 ​​are operated simultaneously for a predetermined period of time, various settings of the bed 1 can be changed in accordance with the multiple operation buttons 43-54 operated simultaneously (only when multiple operation buttons 43-54 are operated simultaneously in a preset combination).

[0042] For example, when the third operation button 39, that is, operation button 53 and operation button 54, are operated simultaneously for a predetermined period of time or more, a setting screen is displayed on the display screen 40, and settings of the bed 1 (movable parts 18, 19, 20, 29) can be changed, such as settings to stop (lock) the drive of the movable parts 18, 19, 20, 29 or to release the locked state, settings to store the current state of the movable parts 18, 19, 20, 29, settings to change the operation mode (linked mode and memory mode) of the movable parts 18, 19, 20, 29, and settings to change the drive speed of the movable parts 18, 19, 20, 29, and settings of the bed 1 (sound generator 41 and vibration generator 42), such as settings for the sound and voice generated from the sound generator 41 and settings for the vibration generated from the vibration generator 42.

[0043] It is also possible to configure the bed 1 settings (for example, the lock setting, memory setting, speed setting, sound setting, and vibration setting) to be changed only when a specific number of operation buttons (for example, the above-mentioned operation button 53 and operation button 54) are operated simultaneously for a predetermined period of time or more, and to prevent the bed 1 settings from being changed when other operation buttons 43 to 52 are operated simultaneously for a predetermined period of time or more. Alternatively, it is also possible to configure the bed 1 settings (for example, the lock setting, memory setting, and speed setting) to be changed when operation button 45 and operation button 46, which are the second operation button 38, are operated simultaneously for a predetermined period of time or more, and to change the settings of the sound generator 41 and vibration generator 42 of the bed 1 (for example, the above-mentioned sound setting and vibration setting) when operation button 47 and operation button 48 are operated simultaneously for a predetermined period of time or more.

[0044] Furthermore, the combination of the multiple operation buttons 43 to 54 may be multiple operation buttons 43 to 54 of the same type among the three types of first operation button 37, second operation button 38, and third operation button 39, or may be multiple operation buttons 43 to 54 of different types.

[0045] Furthermore, the settings of the bed 1 (for example, the drive speeds of the movable parts 18, 19, 20, 29) may be changed only while a plurality of operation buttons 43 to 54 are being operated simultaneously and continuously for a predetermined period of time or longer.

[0046] In the above-mentioned bed 1, when the movable parts 18, 19, 20, 29 reach a predetermined state, the user or the like is not only visually notified using the display screen 40, but also notified by senses other than vision, such as hearing and touch, using the sound generator 41 and the vibration generator 42.

[0047] Here, when the movable parts 18, 19, 20, 29 reach a predetermined state, it is assumed that the back support 8, shoulder support 9, or thigh support 10 reaches an inclination angle that is preset or newly set by the user, or the support base 3 reaches a height that is preset or newly set by the user, or that a malfunction such as an abnormality or breakdown has occurred in the movable parts 18, 19, 20, 29.

[0048] For example, as shown in Fig. 4(b), when the operation button 46 for lowering the support base 3 is operated and the support base 3 is driven and controlled so that it reaches a pre-stored height H2 from a current height H1, when the support base 3 passes a pre-set height H3, a notification is given using the display screen 40, sound generator 41, and vibration generator 42. This makes it possible to prevent feet or objects from getting caught between the floor and the support base 3 when the support base 3 is lowered.

[0049] Furthermore, if a problem occurs in the movable parts 18, 19, 20, 29, not only the error code but also the method for dealing with the problem and the name of the part where the problem occurred are simultaneously displayed on the display screen 40.

[0050] The sound and vibration of the sound generator 41 and vibration generator 42 that are issued in conjunction with the visual notification by the display screen 40 are provided in advance in a number of sound and vibration patterns, such as continuous or intermittent sound and vibration, and the user may be able to select and change any of the sound and vibration patterns, and may also be able to change the strength of the sound and vibration.

[0051] Furthermore, sound patterns and vibration patterns may be changed depending on the state of the movable parts 18, 19, 20, 29 (for example, when the movable parts 18, 19, 20, 29 are in the set state or when a malfunction occurs in the movable parts 18, 19, 20, 29).

[0052] As described above, the bed 1 is configured to have a first operation button 37 for driving the multiple movable parts 18, 19, 20, 29 in conjunction with each other, a second operation button 38 for driving each movable part 18, 19, 20, 29 independently, and a third operation button 39 for changing the operating mode of the multiple movable parts 18, 19, 20, 29 when the first operation button 37 is operated.

[0053] Therefore, in the bed 1 configured as described above, the operation modes of the plurality of movable parts 18, 19, 20, 29 can be easily changed, and the operation can be made comfortable for the user.

[0054] In particular, the bed 1 is configured to have, as operation modes for the multiple movable parts 18, 19, 20, 29, a linked mode in which the multiple movable parts 18, 19, 20, 29 are linked together with a pre-set operation, and a memory mode in which the multiple movable parts 18, 19, 20, 29 are linked together with an operation that is different from the pre-set operation and that is newly set by the user.

[0055] Therefore, the bed 1 having the above configuration can be set to an operation mode desired by each user (suitable for each user).

[0056] In addition, the bed 1 is configured to have two memory modes: a single memory mode in which the multiple movable parts 18, 19, 20, and 29 are operated to reach one state newly added and set by the user, and a multi-memory mode in which the multiple movable parts 18, 19, 20, and 29 are operated to pass through multiple states newly added and set by the user in sequence.

[0057] Therefore, in the bed 1 having the above configuration, it is possible to set the operation mode to be more suited to each user's preference (suitable for each user).

[0058] Furthermore, the bed 1 is configured such that the third operation button 39 is disposed on the same surface as the first or second operation button 37, .

[0059] Therefore, in the bed 1 configured as described above, the user can visually confirm (find) the third operation button 39 at the same time as the first or second operation button 37, 38, thereby improving the operability of the operation unit 36.

[0060] Furthermore, the bed 1 is configured such that at least one of the three types of first to third operation buttons 37, 38, and 39 is different in shape, size, or color from the others.

[0061] Therefore, in the bed 1 configured as described above, the types of the first to third operation buttons 37, 38, 39 can be easily recognized visually and tactilely, which also improves the operability of the operation unit 36.

[0062] In addition, the bed 1 is configured so that when multiple operation buttons 43 to 54 of the operation unit 36 ​​are operated simultaneously for a predetermined period of time, the settings of the bed 1 can be changed in accordance with the multiple operation buttons 43 to 54 that are operated simultaneously.

[0063] Therefore, in the bed 1 having the above configuration, the settings of the bed 1 can be easily changed, and the bed 1 can be operated in a comfortable manner for the user.

[0064] In particular, the bed 1 has one or more types of operation buttons 43-54, including one or more first operation buttons 37 (operation buttons 43, 44) for driving the multiple movable parts 18, 19, 20, 29 in conjunction with one another, one or more second operation buttons 38 (operation buttons 45-52) for driving each movable part 18, 19, 20, 29 independently, and one or more third operation buttons 39 (operation buttons 53, 54) for changing the operation mode of the multiple movable parts 18, 19, 20, 29 when the first operation button 37 is operated.When multiple operation buttons 43-54 of the same type or different types of operation buttons 43-54 are operated simultaneously for a predetermined period of time, the settings of the bed 1 can be changed according to the multiple operation buttons 43-54 that are operated simultaneously.Therefore, the settings of the bed 1 can be easily changed using the existing operation buttons 43-54.

[0065] In addition, since the drive speed of the movable parts 18, 19, 20, and 29 is changed only while multiple operation buttons 43 to 54 are being operated simultaneously, the drive settings of the movable parts 18, 19, 20, and 29 can be easily changed only for the time desired by the user.

[0066] Furthermore, the bed 1 is configured to provide a visually recognizable notification on the display screen 40 when the movable parts 18, 19, 20, 29 reach a predetermined state, and also to provide a non-visually recognizable notification.

[0067] Therefore, in the bed 1 having the above configuration, the user or the like can easily recognize that the movable parts 18, 19, 20, 29 are in a predetermined state.

[0068] In particular, if a malfunction occurs in the operation of the movable parts 18, 19, 20, 29, the display screen 40 is configured to simultaneously display an error code, a method for dealing with the malfunction, or the name of the part where the malfunction occurred, so that a quick response can be made when a malfunction occurs.

[0069] In addition, as a notification that can be recognized by senses other than sight, the device is configured to use either vibration from vibration generator 42 or sound (which can also be voice) from sound generator 41, or both, so that the user can easily recognize that movable parts 18, 19, 20, 29 have reached a predetermined state through vibration or sound.

[0070] Furthermore, since the vibration and / or sound pattern is changeable, the user can change it to a desired pattern.

[0071] Furthermore, since the device has a plurality of vibration and / or sound patterns and is configured to allow selection of any one of the patterns, the user can select the pattern they desire. [Explanation of symbols]
