[0008] The beds proposed in Patent Documents 1 to 3 can facilitate care by caregivers by tilting the entire bed. Specifically, it can be used when the person being cared for turns over or changes body position. However, at the nursing site, the person being cared for often stands up from a lying position in bed with the help of a caregiver or by their own strength. The beds proposed in Patent Documents 1 to 3 do not take such usage into consideration. It is undeniable that if the bed is tilted to assist the person being cared for standing up from a lying position, the person being cared for may roll off the bed. Summary of the invention

[0009] The present invention has been made in view of the above-mentioned problems, and provides a nursing bed in which a care receiver can easily raise his / her upper body from a lying position on the bed and stand on the floor or the like.

[0010] The invention for solving the above-mentioned problem is the following nursing bed: it includes a bed body, the bed body has a first support part for supporting the lower body and a second support part for supporting the upper body, the bed body is divided into the first support part and the second support part at least along the width direction of the bed body, and the first support part is a movable body that can rotate around a rotation axis extending along the long side direction of the bed body.

[0011] According to this configuration, the inclination angle of the first support portion can be freely set, so the lower body can be inclined by inclining the first support portion. Thus, the care receiver can easily place the lower body on the floor and stand up.

[0012] In addition, the "lower body" refers to the area from the thigh down, and does not necessarily include the buttocks. In addition, regarding the thigh, it is not necessary to include the entire thigh, and it is sufficient to include a part of the thigh.

[0013] In addition, the "upper body" refers to the area from the back upwards, and does not necessarily include the waist and buttocks. In addition, regarding the back, it is not necessary to include the entire back, and it is sufficient to include a part of the back.

[0014] The present invention may also be configured such that: the second support portion is a movable body that can rotate around the rotation axis, and the first support portion and the second support portion can rotate around the rotation axis independently of each other. In addition, the expression about rotation around the rotation axis includes clockwise rotation and counterclockwise rotation.

[0015] According to this structure, the inclination angles of the first support part and the second support part can be freely set, so that, for example, by making the inclination angle of the first support part larger than the inclination angle of the second support part, the lower body can be tilted larger than the upper body. Thus, the person being cared for can easily lift the upper body and stand up without feeling the risk of falling off the bed.

[0016] Preferably, the rotation axis is located above the first support portion and the second support portion.

[0017] According to this structure, the rotation axis is located above the first support part and the second support part, so the bed becomes a swinging mechanism like a hammock. Therefore, when the bed rotates, the person being cared for on the bed is supported while being pressed against the two support parts. As a result, the person being cared for can avoid the anxiety of falling from the bed.

[0018] Preferably, a first drive unit that rotates the first support unit around the rotation axis and a second drive unit that rotates the second support unit around the rotation axis are provided.

[0019] According to this configuration, the first drive unit that rotates the first support unit around the rotation axis and the second drive unit that rotates the second support unit around the rotation axis are provided, so that the rotation functionality is improved and the caregiver or the person being cared for can easily rotate the bed.

[0020] Preferably, a control unit is provided that generates a control signal for instructing the operation of the first drive unit and the second drive unit, and outputs the control signal to the first drive unit and the second drive unit.

[0021] According to this configuration, since the control unit that instructs the operation of the first drive unit and the second drive unit by means of a control signal is provided, the first support unit and the second support unit can be set to an appropriate tilting state according to the condition of the care receiver.

[0022] Preferably, the control unit outputs a first signal to the first drive unit instructing the rotation of the first support unit, and after the instruction is completed, outputs a second signal to the first drive unit and the second drive unit instructing the rotation of the first support unit and the second support unit to further increase the inclination angle of the first support unit.

[0023] According to this structure, the control unit outputs a first signal to the first drive unit to instruct the rotation of the first support unit, and after the instruction is completed, outputs a second signal to the first drive unit and the second drive unit to instruct the rotation of the first support unit and the second support unit and to further increase the inclination angle of the first support unit, so that the care recipient can stand up from the bed without feeling rolling. Preferably, the first support unit and the second support unit are rotated simultaneously in the second action.

[0024] It is preferable that the rotation angles of the first support portion and the second support portion in the second operation are the same.

[0025] According to this configuration, the first support and the second support have the same rotation angle in the second action, so the rotation speeds of the first support and the second support in the second action can be set to be the same. As a result, the care receiver can rotate in a comfortable state without feeling uncomfortable.

[0026] Preferably, the first support portion rotates at an angle of 2 to 5 degrees in response to the first signal.

[0027] According to this structure, by setting the rotation angle of the first support part in response to the first signal to a range of 2 to 5 degrees, the care recipient can easily get up from a lying position and stand up smoothly from the bed. When the rotation angle of the first support part is smaller than 2 degrees or larger than 5 degrees, it is difficult for the care recipient in a lying position to stand up smoothly from the bed.

[0028] Preferably, the first support portion and the second support portion rotate at an angle of 2 to 5 degrees in response to the second signal.

[0029] According to this structure, by setting the rotation angle of the first support part and the second support part in response to the second signal to a range of 2 to 5 degrees, the person being cared for can easily get up from a lying position and stand up smoothly from the bed. Preferably, the first support part and the second support part rotate simultaneously in response to the second signal. In the case where the rotation angle of the first support part and the second support part is less than 2 degrees or greater than 5 degrees, it is difficult for the person being cared for in a lying position to stand up smoothly from the bed.

[0030] The second supporting portion of the present invention may be a fixed body.

[0031] According to this configuration, since the second support portion for supporting the upper body is fixed, it is possible to suppress an increase in the number of components constituting the nursing bed, thereby achieving cost reduction.

[0032] Preferably, the rotation axis is located above the first support portion.

[0033] According to this configuration, when the first support portion rotates, the care receiver on the bed is supported in a state of being pressed against the first support portion. Thus, the care receiver can avoid the anxiety of falling from the bed.

[0034] Preferably, a driving unit is provided to rotate the first support unit around the rotation axis.

[0035] According to this configuration, since the driving unit that rotates the first support unit around the rotation axis is provided, the rotation functionality of the bed is improved, and the caregiver or the person being cared for can easily rotate the bed.

[0036] Preferably, a control unit is provided that generates a control signal for instructing the operation of the drive unit and outputs the control signal to the drive unit.

[0037] According to this configuration, since the control unit that instructs the operation of the drive unit by means of a control signal is provided, the first support unit can be brought into an appropriate tilting state according to the condition of the care receiver.

[0038] Preferably, the first support portion rotates at an angle of 2 to 5 degrees in response to the control signal.

[0039] According to this structure, by setting the rotation angle of the first support part to the range of 2 to 5 degrees, the care recipient can easily get up from the lying state and stand up smoothly from the bed. When the rotation angle of the first support part is smaller than 2 degrees or larger than 5 degrees, it is difficult for the care recipient in the lying state to stand up smoothly from the bed.

[0052] Below, refer to Figures 1 to 10 Embodiments of the nursing bed of the present invention will be described in detail.

[0053] Figure 1 1 is a front view of the nursing bed 1. The nursing bed 1 includes a bed body 10, and the bed body 10 has a first support portion 11 for supporting the lower body and a second support portion 22 for supporting the upper body. The bed body 10 is at least in the width direction W ( Figure 1 The direction perpendicular to the paper surface, reference Figure 7 , 8 ) is divided into a first support portion 11 and a second support portion 22, and the first support portion 11 and the second support portion 22 are movable bodies 11a and 22a that can rotate around a rotation axis RS extending along the long side direction L of the bed body 10. For the nursing bed 1, according to the instruction from the control unit 2, the first support portion 11 can rotate around the rotation axis RS by the operation of the first drive unit 30, and the second support portion 22 can rotate around the rotation axis RS by the operation of the second drive unit 40 ( Figure 7 , 8 The rotation of the first support part 11 and the rotation of the second support part 22 can be realized independently. The first support part 11 supports the lower body, and the second support part 22 supports the upper body. In addition, the first support part 11 and the second support part 22 are simultaneously lifted and lowered by the same distance by the operation of the lifting drive part 50, and the front end 22e of the second support part 22 is rotated from the lying position to the standing direction by the operation of the reclining drive part 60. The first drive part 30, the second drive part 40, the lifting drive part 50 and the reclining drive part 60 receive instructions from the control part 2 and operate.

[0054] In the present embodiment, the nursing bed 1 is divided into two parts and has the first support part 11 and the second support part 22, but the present invention is not limited thereto. For example, a part for supporting the buttocks may be added and the nursing bed 1 may be divided into three parts.

[0055] In this embodiment, "supporting the lower body" is to support the lower part of the thigh, and does not necessarily mean supporting the buttocks. In addition, about the thigh, it is not necessary to support all, and a part of the thigh can be supported.

[0056] In addition, "supporting the upper body" means supporting the upper part of the back, and does not necessarily mean supporting the waist and buttocks. In addition, regarding the back, it is not necessary to support the entire back, and it is sufficient to support a part of the back.

[0057] The rotation axis RS is located above the first support portion 11 and the second support portion 22, and extends in the long side direction L of the bed body 10 in parallel with the first support portion 11 and the second support portion 22. Here, the long side direction L is the direction in which the first support portion 11 and the second support portion 22 are arranged in a row. In addition, when viewed from the side, it is located at a position equidistant from both side ends extending along the long side direction L of the nursing bed 1.

[0058] like Figure 2 As shown in the figure, the piston 52a of the lifting actuator 52 is advanced / retreat by the lifting driving unit 50, and the lifting link mechanism 51 is lifted and lowered with the rotation. One end of the lifting actuator 52 is rotatably connected to the base 53, and the other end is rotatably connected to the lifting link mechanism 51. By advancing and retracting the piston 52a, the lifting actuator 52 and the lifting link mechanism 51 are lifted / lowered with the rotation. The first support part 11 and the second support part 22 supported by the lifting link mechanism 51 are also lifted and lowered with the lifting / lowering of the lifting link mechanism 51.

[0059] The lifting link mechanism 51 is a component for lifting the support frame 14. In addition, the support frame 14 supports the first support portion 11 and the second support portion 22. Figure 3 As shown, the lifting link mechanism 51 is a structure in which lifting link members 56 and 57 are connected via a connecting rod 58, one end of which is rotatably connected to the base 53, and the other end of which is rotatably connected to the support frame 14. The lifting link members 56 and 57 are synchronously displaced by being connected by the connecting rod 58. A connecting member 59 for rotatably connecting the lifting actuator 52 is installed in the middle part of the lifting link member 56.

[0060] like Figure 4 , 5 As shown, the reclining driving unit 60 includes a reclining actuator 62 and a reclining link mechanism 61. One end of the reclining actuator 62 is rotatably connected to the second support frame 72, and the other end is rotatably connected to the reclining link mechanism 61. One end of the reclining link mechanism 61 is rotatably connected to the second support frame 72, and the other end is rotatably connected to the second support portion 22. The end portion of the second support portion 22 near the first support portion 11 is rotatably connected to the second support frame 72. The reclining driving unit 60 is configured such that the reclining link mechanism 61 is raised and lowered with the rotation by the piston 62a of the reclining actuator 62 moving forward / backward. The front end portion 22e of the second support portion 22 is rotated from the lying position to the standing direction by the piston 62a moving forward. In addition, the second support portion 22 moves to the original position in a manner of lying down in the direction of the second support frame 72 while the front end portion 22e is rotated downward as shown in the figure by the piston 62a moving backward.

[0061] The reclining link mechanism 61 includes a pair of reclining link members 66, 66 and a connecting rod 67. One end of the reclining link member 66 is rotatably connected to the second support frame 72, and the other end is rotatably connected to the second support portion 22. In addition, the middle portion has a hinge portion for rotating each member. The connecting rod 67 is a member connecting the pair of reclining link members 66, 66, and the end portion is rotatably connected to the middle portion of the reclining link member 66. A connecting member 68 for rotatably connecting to the reclining actuator 62 is installed at the middle portion of the connecting rod 67.

[0062] The first support portion 11 is fixed to the first support frame 71. In addition, the first support portion 11 is supported by the support frame 14 (see Figure 1 ).like Figure 6 , 7 8, the first driving part 30 has a first actuator 31 and a pair of first guide parts 32. The first actuator 31 is located between the pair of first guide parts 32, 32. One end of the first actuator 31 is rotatably connected to the support frame 14, and the other end is rotatably connected to the connection frame 38 via a connection member 39. The connection frame 38 is a member mounted on both side ends of the first support frame 71.

[0063] The first guide portion 32 is a member mounted on both side ends of the first support frame 71 and has an arc-shaped first guide frame 33. The first guide frame 33 is held by rollers 35 rotatably fixed to the guide frame fixing portion 34. The guide frame fixing portion 34 is fixed to the support frame 14.

[0064] The first guide portion 32 rotates around the rotation center axis by the advance / retraction of the piston of the first actuator 31. Specifically, the first guide frame 33 moves in the direction of the piston 31a. Figure 8 The first guide frame 33 rotates clockwise in the middle, and the piston 31a moves backward to rotate the first guide frame 33 counterclockwise.

[0065] The end portion of the second support portion 22 near the first support portion 11 is rotatably fixed to the second frame. Figure 1 ).like Figure 6 As shown, the second driving unit 40 includes a second actuator 41, a pair of second guides 42, 42, a guide frame fixing portion 44, and a roller 45. The structures of the second actuator 41, the second guide 42, the guide frame fixing portion 44, and the roller 45 are almost the same as the structures of the first actuator 31, the first guide 32, the guide frame fixing portion 34, and the roller 35, respectively, so the description thereof is omitted.

[0066] Fig. 9: shows the structure of the control unit 2. The electronic control unit (hereinafter referred to as ECU) is composed of a microcomputer composed of a CPU, a RAM, a ROM, and an I / O interface (all omitted in the figure). The ECU 3 is connected to the operating panel 5, and the signals sent from the operating panel 5 are sequentially input. The output side of the ECU 3 is connected to the first actuator 31, the second actuator 41, the lifting actuator 52, and the reclining actuator 62.

[0067] Reference Fig. 9 , 10 The operation of the first support portion 11 and the second support portion 22 from the initial state when the operating panel 5 is operated is described. Here, the initial state refers to a state in which the first support portion 11 and the second support portion 22 are horizontal to the installation surface when the nursing bed 1 is placed on the horizontal installation surface and the distance from the ground surface to the first support portion 11 and the second support portion 22 is the smallest.

[0068] By pressing the button PB0 , the operation panel 5 is energized to send a signal to the ECU 3 .

[0069] When the button PB1 is pressed, the first actuator 31 and the second actuator 41 are activated, and the pistons 31a and 41a move forward in proportion to the time the button PB1 is pressed. As a result, the first support portion 11 and the second support portion 22 are simultaneously raised by the same distance (see Fig.10 (a)). The height that can be raised is determined by the distance that the pistons 31a and 41a can move forward.

[0070] When the button PB2 is pressed, the first actuator 31 and the second actuator 41 are actuated in accordance with the pressing time, and the pistons 31a and 41a in the advanced state are moved backward in proportion to the time the button PB2 is pressed. As a result, the first support part 11 and the second support part 22 in the raised state are simultaneously lowered by the same distance (see Fig.10 (a)). The distance the piston can fall back is determined by the distance it can move.

[0071] When the button PB3 is pressed, the reclining actuator 62 is actuated in accordance with the pressing time, and the piston 62a moves forward. As a result, the second support portion 22 rotates in the direction of the first support portion 11 (see Fig.10 (b)). The rotatable angle is determined by the distance the piston 62a can advance.

[0072] When the button PB4 is pressed, the reclining actuator 62 is actuated in accordance with the pressing time, and the piston 62a in the advanced state moves backward. As a result, the second support portion 22 in the rotated state rotates in a direction away from the first support portion 11 (see Fig.10 (b)). The rotation stops when the piston 62a is located on the same plane as the first support portion 11. At this time, it is preferably a distance at which the piston 62a cannot move further backward.

[0073] When the button PB5 is pressed, the first actuator 31 is activated and the piston 31a moves forward. As a result, the first support 11 rotates from the horizontal state around the rotation axis RS within a range of 3 to 5 degrees (see Fig.10 (c). Hereinafter, the symbol "~" indicates a range). A more preferred rotation angle is 3 to 4 degrees. After the first support portion 11 is rotated, the first actuator 31 and the second actuator 41 are simultaneously actuated, and the pistons 31a and 41a move forward. As a result, the first support portion 11 is further rotated by 3 to 5 degrees, and the second support portion 22 is rotated by 3 to 5 degrees (refer to Fig.10 (d)). A more preferred rotation angle is 3 to 4°. The above series of rotation actions are continuously performed by pressing the button PB5. As a result, the first support part 11 and the second support part 22 are respectively rotated 6 to 10° and 3 to 5° in the same direction. The rotation angle of the first support part 11 supporting the lower body is larger than the rotation angle of the second support part 22 supporting the upper body, so that the person being cared for lying on the nursing bed 1 can easily get up from the nursing bed 1 and go down to the floor, etc. By pressing the button PB5 again, the first actuator 31 and the second actuator 41 are activated, and the first support part 11 and the second support part 22 return to the position before the rotation.

[0074] When the button PB6 is pressed, the second actuator 41 is activated, and the piston 41a repeatedly moves forward and backward. As a result, the second support 22 repeatedly rotates ±3° around the rotation axis RS in a cycle of about 5 seconds from the horizontal state (see Fig.10 (e)). By pressing the button PB5 again, the rotation stops and the second support part 22 returns to the initial horizontal state. In addition, the rotation angle can be changed by pressing the button PB9 when the second support part 22 rotates. If pressed once, the rotation angle is ±5°, if pressed twice, the rotation angle is ±8°, and if pressed three times, it returns to the initial rotation angle of ±3°.

[0075] When the button PB7 is pressed, the first actuator 31 is activated, and the piston 31a repeatedly moves forward and backward. As a result, the first support 11 repeatedly rotates ±3° around the rotation axis RS in a cycle of about 5 seconds from the horizontal state (see Fig.10 (f)). By pressing the button PB5 again, the rotation stops and the second support part 22 returns to the initial horizontal state. In addition, the rotation angle can be changed by pressing the button PB9 when the first support part 11 rotates. If pressed once, the rotation angle is ±5°, if pressed twice, the rotation angle is ±8°, and if pressed three times, it returns to the initial rotation angle of ±3°.

[0076] When the button PB8 is pressed, the first actuator 31 and the second actuator 41 are both activated, and the pistons 31a and 41a repeatedly move forward and backward. As a result, the first support 11 and the second support 22 synchronously rotate from the horizontal state around the rotation axis RS by ±3° in a cycle of about 5 seconds (see Fig.10 (g)). By pressing the button PB5 again, the rotation is stopped and the first support part 11 and the second support part 22 return to the initial horizontal state. In addition, the change of the rotation angle can be achieved by pressing the button PB9 when the first support part 11 and the second support part 22 are rotating. If pressed once, the rotation angle is ±5°, if pressed twice, the rotation angle is ±8°, and if pressed three times, it becomes the initial rotation angle ±3°. By the first support part 11 and the second support part 22 rotating periodically at the same time, a sleeping effect can be obtained.

[0077] In addition, from the viewpoint of ensuring the safety of the care receiver, some restrictions are placed on the movement and displacement of the first support portion 11 and the second support portion 22 .

[0078] <Restriction 1>

[0079] In a state where the second support portion 22 is rotated by pressing the button PB3 , even if any one of the buttons PB6 , PB7 , and PB8 is pressed, the first support portion 11 and the second support portion 22 do not rotate about the rotation axis RS.

[0080] <Restriction 2>

[0081] When any one of buttons PB5, PB6, PB7, PB8 is pressed, the signal that would be sent when the other buttons are pressed is not sent to ECU 3. That is, the action of the first actuator 31, etc. when the other buttons are pressed is not reflected.

[0082] <Restriction 3>

[0083] When the first support portion 11 and the second support portion 22 are tilted, even if any one of the buttons PB5, PB6, PB7, and PB8 is pressed, the signal that would be sent when the button is pressed is not sent to the ECU 3. That is, in this state, even if any one of the buttons PB5, PB6, PB7, and PB8 is pressed, the first support portion 11 and the second support portion 22 do not rotate around the rotation axis RS.

[0084] <Modification>

[0085] In this embodiment, the first support portion 11 and the second support portion 22 rotate independently, but the present invention is not limited thereto. Fig.11As shown, the second support part 22 may also be a fixed body 22b that has been fixed. In this case, the second drive part 40 is not required, and the number of components required for the nursing bed 1 can be reduced. Fig.12 As shown in (a) and (b) of FIG. 8 , the position of the rotation axis RS is not limited to above the first support portion 11 and the second support portion 22 , but may also be a position passing through the first support portion 11 and the second support portion 22 .

[0086] The present embodiment is merely an example and can of course be modified without departing from the technical concept of the present invention.

[0087] Industrial Applicability

[0088] The nursing bed according to the present invention can also be expected to have a soothing effect and a relaxing effect, so it can be used not only for healthy people but also for people being cared for, and thus has great industrial applicability.
