Detailed Description

1. The structure of the auxiliary device 1 of the first embodiment

The configuration of the assist device 1 according to the first embodiment will be described with reference to fig. 1 to 4. The assist device 1 is used for, for example, transfer between two different positions, such as transfer between a bed and a wheelchair, and transfer between a wheelchair and a toilet seat. The support device 1 supports the upper body of the person to be supported, and supports the standing motion from the sitting posture to the standing posture, and supports the sitting motion from the standing posture to the sitting posture.

Herein, the standing posture refers to a posture in which the buttocks are lifted from the seating surface and the legs are straightened, and includes a standing posture and a stooping posture. That is, the standing posture includes a standing posture in which the upper body is substantially upright, a forward stooping posture in which the upper body is tilted forward, and the like. The assist device 1 can transfer the person to be assisted in the standing position when the two positions for transfer are away from each other. The assist device 1 includes a base 2, an operating member 3, a support member 4, an actuator 5, a knee contact member 6, a position adjustment unit 7, an angle adjustment unit 8, a control unit not shown, and the like.

The base 2 is formed of a foot rest 21, a base lever 25, a mounting plate 26, a front wheel 28, and the like. The foot rest 21 is disposed substantially horizontally near the floor surface F. The foot placement table 21 is a portion on which the assisted person places his/her feet. The actuator support 22 is provided upward at the front side of the upper surface of the foot placement table 21. A pair of left and right rear wheels 23 are provided at left and right sides of the rear portion of the lower surface of the foot rest 21. The pair of right and left centering wheels 24 are provided on the lower surface of the foot rest 21 on the right and left sides on the front side.

A pair of right and left base rods 25 are provided at right and left sides of the front side of the foot rest 21, respectively. The abutment lever 25 extends forward and is bent upward. A pair of left and right mounting plates 26 are provided perpendicularly to the bent upper portion of the base rod 25. Swing support seats 27 are provided on the front sides of the upper portions of the pair of left and right mounting plates 26, respectively. A pair of left and right front wheels 28 are provided on the front sides of the lower portions of the pair of left and right mounting plates 26. The steering function of the front wheels 28 and the rear wheels 23 allows the assist device 1 to perform not only straight-running movement and turning movement but also lateral movement and in-situ turning. The front wheel 28 also has a lock function for restricting movement.

The position adjusting portion 7 is disposed above the pair of left and right mounting plates 26. The position adjustment unit 7 is a manual adjustment mechanism for adjusting the position of the knee abutment member 6 in the front-rear direction according to the physical constitution of the assisted subject or the like. The knee abutment member 6 is a member for abutment of the knee of the assisted person. The knee abutment member 6 defines the position of the knee, and stabilizes the standing motion and seating motion of the assisted person. The knee contact member 6 is formed of a base plate 61, a support rod 62, a hard cushioning member 63, a soft cushioning member 64, and the like.

As shown in fig. 1, the substrate 61 is arranged to be slightly tilted forward compared to the vertical direction. The substrate 61 extends in the left-right direction, and the left and right sides are bent obliquely rearward. A pair of support bars 62 extending obliquely downward toward the front are provided on the left and right sides of the front surface of the base plate 61. The substrate 61 and the support bar 62 are formed using a metal material such as aluminum.

The hard buffer member 63 is disposed in contact with the rear side of the substrate 61. The soft cushioning member 64 is disposed in contact with the rear side of the hard cushioning member 63. The hard buffer member 63 and the soft buffer member 64 are bent obliquely rearward on the right and left sides as the substrate 61. The hard cushion member 63 and the soft cushion member 64 are formed using an elastically deformable material such as polyurethane foam. However, the soft cushioning material 64 has a lower rebound resilience than the hard cushioning material 63, and is easily elastically deformed. The knees of the assisted person are abutted against the rear surface of the soft cushioning member 64. The hard cushioning material 63 and the soft cushioning material 64 are covered with a cloth or leather boot 65.

The position adjusting portion 7 is constituted by a pair of left and right slide supporting portions 71, a slide moving portion 72, and a positioning pin 73. The slide support portion 71 is a metal cylindrical member extending in the front-rear direction, and is fixed above the mounting plate 26. A pin hole 74 is bored in the upper surface of the rear portion of the slide support portion 71. The sliding movement portion 72 is a metal round bar-shaped member extending in the front-rear direction, and is fixed to the front side of the support rod 62 of the knee contact member 6. The slide moving portion 72 slides in the front-rear direction inside the slide supporting portion 71. A plurality of positioning holes aligned in the front-rear direction are provided on the upper surface of the slide moving portion 72. The positioning pin 73 is inserted into the pin hole 74 of the slide support portion 71, and is then inserted into any one of the positioning holes of the slide moving portion 72. Thereby, the position of the knee abutment member 6 in the front-rear direction is adjusted.

The operating member 3 is operable at least in the up-down direction with respect to the base 2. As shown in fig. 1, the operating member 3 is formed in an arm shape bent halfway in a side view. A pair of left and right swing shafts 32 are provided at the lower portion of the operating member 3. The swing shaft 32 is swingably supported by the swing support base 27 of the mounting plate 26. In order to limit the swing angle range of the operating member 3, a stopper mechanism, not shown, is provided in the vicinity of the swing support base 27. Thus, the operating member 3 can swing in the front-upper direction and the rear-lower direction with respect to the base 2. The swing of the operating member 3 in the forward and upward direction (swing of clockwise rotation in fig. 1) assists the standing operation of the assisted person. Further, the swing of the operating member 3 in the backward and downward direction assists the seating operation of the assisted person.

A battery, not shown, and a link mechanism are housed in the operating member 3. The battery serves as a power source for the actuator 5 and the control unit. The applicant of the present application disclosed a detailed structural example of the link mechanism in international publication No. 2018/167856. A swing support part, which is omitted from the reference numerals, is provided on the rear side of the upper part of the operating member 3, and a swing member 45 is provided on the swing support part. The swinging member 45 swings with respect to the operating member 3. However, in the initial state before the assisted person contacts the support member 4, the swing member 45 is restricted from swinging by the link mechanism.

As shown in fig. 1 to 3, the swinging member 45 has the base plate 42 on the rear side. The substrate 42 is formed into a substantially rectangular shape using a metal or resin plate material having high rigidity. The base plate 42 corresponds to a mount provided on the operating member 3 and to which the support member 4 is attached. The base plate 42 has a handle 46 on the front surface. The handle 46 is formed in a substantially quadrangular frame shape and extends upward of the operating member 3. The handle 46 is a portion to be gripped by the assisting person, and is also a portion to be gripped by the assisting person in order to move the assisting apparatus 1.

The support member 4 is in contact with the front surface of the upper body of the assisted person to support the assisted person. The support member 4 is formed to include an upper body support member 41 and a pair of left and right underarm support members 47. The upper body support member 41 is attached to the rear surface of the base plate 42 via the angle adjusting section 8. In fig. 2, a spacer 81, which will be described later, constituting the angle adjuster 8 is not used. The upper body support member 41 is set at a forward inclined mounting angle in an initial state. The entire support member 4 is coupled to the swing support portion of the operating member 3 via the base plate 42 and the swing member 45, and swings around the swing support portion. The forward swing (clockwise swing in fig. 1) of the support member 4 assists the raising operation of the assisted person. Further, the rearward swing of the support member 4 assists the seating motion of the assisted person.

As shown in fig. 1 to 4, the upper body support member 41 is formed of a hard cushioning member 43, a soft cushioning member 44, and the like. The hard buffer member 43 is disposed close to the substrate 42. The soft cushioning member 44 is disposed in contact with the rear side of the hard cushioning member 43. The hard cushion member 43 and the soft cushion member 44 are formed using an elastically deformable material such as polyurethane foam. However, the soft cushioning member 44 has a lower elasticity than the hard cushioning member 43, and is easily elastically deformed. The front surface of the upper body of the assisted person, in other words, the chest-to-abdomen belt, is in contact with the rear surface of the soft cushioning member 44.

The pair of right and left underarm support members 47 are attached to the base plate 42 and disposed on both right and left sides of the upper body support member 41. The underarm support member 47 is formed in an L-shape bent at an obtuse angle. The underarm support member 47 is formed of a core member, an outer peripheral member, and the like, which are not shown. The core member is formed by bending a round rod or tube made of metal or hard resin, for example. The outer peripheral member is formed in a cylindrical shape using a cushioning material to cover the outer periphery of the core member. The short linear portion of the armpit supporting member 47 from the base end of the mounting side to the bending position is a shoulder receiving portion, and the long linear portion from the bending position to the tip end is an armpit entering portion. The shoulder receiving portion supports the front surface of the shoulder of the assisted person. The armpit entry portion enters the armpit of the assisted person to support the upper body. The upper body support member 41 and the underarm support member 47 may be covered with a cloth or leather protective cover.

The actuator 5 is a telescopic actuator, and is composed of a main body 51, a movable portion 52, a motor 53, and the like. The main body 51 is a cylindrical member having a large diameter and long in the vertical direction, and has an opening portion that opens upward. The lower end of the main body 51 is supported by the actuator support 22 of the base 2. The movable portion 52 is a round bar-shaped member having a small diameter and long in the vertical direction. The upper end of the movable portion 52 is connected to the link mechanism of the operating member 3. The lower portion of the movable portion 52 is fitted into the opening of the main body 51.

The motor 53 is mounted on the front side of the lower portion of the main body 51. The motor 53 controls the direction of the current flowing through a control unit, not shown, and drives the expansion operation and the contraction operation of the movable unit 52. The movable portion 52 is driven by the motor 53 to perform a telescopic operation with respect to the main body 51. Fig. 1 shows an initial state in which the movable portion 52 is contracted and the actuator 5 is shortened. The actuator 5 may use other types of driving sources such as a pressure driving source using hydraulic pressure or air pressure instead of the motor 53.

The actuator 5 performs a first extension operation from the shortened length to a predetermined intermediate length, a second extension operation from the intermediate length to the extended length, and a contraction operation from the extended length to the shortened length via the intermediate length. The first extension operation of the actuator 5 is transmitted to the swing member 45 via the link mechanism. Thereby, the support member 4 swings forward together with the swing member 45. The second extension operation of the actuator 5 is transmitted to the operating member 3 via the link mechanism. Thereby, the operating member 3 swings in the front-upper direction. By the contraction operation of the actuator 5, the operation member 3 swings in the backward and downward direction, and then the support member 4 swings in the backward direction.

The control unit, not shown, is constituted by an operator, a control body, and the like. The operator has an up button and a down button for operating the actuator 5. The operator is operated by the helper. The control main body is configured using a computer device having a CPU and operated by software. The control main body section controls the presence or absence of a current flowing to the motor 53 of the actuator 5 and the direction of the current flow based on operation information of the up button and the down button. Thereby, the operation of the actuator 5 is controlled, and the switching between the stop operation and the expansion operation and the contraction operation is performed.

2. Structure of angle adjusting part 8

Next, the structure of the angle adjuster 8 will be described in detail. The angle adjustment unit 8 adjusts the attachment angle of the support member 4 to the operating member 3 in an initial state between the contact of the support member 4 with the person to be assisted. Therefore, the angle change of the support member 4 and the angle change of the support member 4 due to the action from the assisted person are not included in the adjustment of the mounting angle, which is accompanied by the progress of the assisting operation of the assisting apparatus 1 after the completion of the adjustment.

The angle adjusting portion 8 includes a spacer 81, and the spacer 81 is wedge-shaped when viewed from the side and is detachably inserted between a mount provided in the operating member 3 and the support member 4. As shown in fig. 4, the pad 81 is formed in a tapered shape having a thickness W on the lower side and a tapered shape on the upper side. The pad 81 extends in the left-right direction and has a width dimension equal to that of the upper body support member 41. In order to stably attach the support member 4 to the base plate 42, surface fasteners 85 are provided at upper and lower portions of the front side of the upper body support member 41, regardless of the presence or absence of the pad 81.

The surface fastener 85 is composed of a hook surface 86 having hook-like fuzzing and a loop surface 87 having loop-like fuzzing. In the upper surface fastener 85, one of the hook surface 86 and the loop surface 87 extends forward from the upper body support member 41 through the upper portion of the pad 81 and the upper portion of the base plate 42. The other of the hook surface 86 and the annular surface 87 extends forward from the upper body support member 41 through the through hole provided in the base plate 42 via the upper side of the pad 81. The hook surface 86 and the loop surface 87 are curved to overlap each other and are bonded to each other in close contact with the front side of the base plate 42.

In the lower surface fastener 85, one of the hook surface 86 and the loop surface 87 extends forward from the upper body support member 41 through the lower portion of the pad 81 and the lower portion of the base plate 42. The other of the hook surface 86 and the annular surface 87 extends forward from the upper body support member 41 through a through hole provided in the base plate 42 via the lower side of the pad 81. The hook surface 86 and the loop surface 87 are curved to overlap each other and are bonded to each other in close contact with the front side of the base plate 42.

Thus, the spacer 81 is stably held between the upper and lower surface fasteners 85, and is prevented from falling off. Further, since the operation of attaching and detaching the pad 81 is only performed on the upper surface fastener 85, it is easy and can be completed in a short time. In addition, when the spacer 81 is not used, the contact portion of the upper surface fastener 85 is adjusted so as to avoid a gap between the support member 4 and the substrate 42. Further, the upper body supporting member 41 can be detached as a whole by opening the upper and lower face fasteners 85.

Fig. 2 shows a case where the mounting angle of the support member 4 is adjusted to the standard body type angle by the angle adjustment unit 8 in accordance with the standard body type of the subject. As shown in the figure, the spacer 81 serving as the angle adjuster 8 is not used. In the present specification, the standard body shape refers to a body shape having no large difference between the chest circumference and the abdomen circumference.

On the other hand, fig. 3 shows a case where the mounting angle of the support member 4 is adjusted to the angle for the fat body type by the angle adjustment unit 8 corresponding to the assisted person of the fat body type. As shown in the figure, a cushion 81 is interposed between the base plate 42 and the upper body support member 41. Thereby, the mounting angle of the support member 4 approaches the upright direction due to the reduced degree of forward tilting. In the present specification, the fat body type means a body type having a relatively large abdominal circumference as compared with the chest circumference, for example, a visceral fat type fat body type. Therefore, an obese state in which both the chest circumference and the abdomen circumference are large compared with the height does not belong to an obese body type.

The angle adjustment section 8 selectively adjusts two mounting angles of the support member 4 by selecting whether or not to use the pad 81. The angle adjusting unit 8 may be adjusted to any one of three or more attachment angles according to the degree of obesity of the subject. For example, by preparing a plurality of pads 81 having a small thickness W in advance, the angle adjustment unit 8 can variably adjust the number of inserts of the pads 81. For example, by preparing a plurality of pads 81 having different thicknesses W in advance, the angle adjusting unit 8 can select any pad 81.

3. Operation of the auxiliary device 1 of the first embodiment

Next, the operation of the assist device 1 according to the first embodiment will be described. The following describes a case of assisting the standing motion of the assisted person from the sitting posture. The assisting person first returns the actuator 5 to the shortened length to the initial state shown in fig. 1. Then, the assisting person holds the grip 46 and moves the assisting apparatus 1, and brings the assisting apparatus 1 close to the assisted person in the sitting posture. Next, the assisting person operates the angle adjusting unit 8 to adjust the mounting angle of the support member 4 in accordance with the body shape of the assisting person. The assisting person operates the position adjusting unit 7 to position the knee contact member 6 at an appropriate position in accordance with the physical constitution of the assisting person or the like. Thereby, the preparation using the auxiliary device 1 is completed.

The assisted person brings the lower body into the area below the support member 4 and places both feet on the foot placement table 21. The assisted person obtains a stable posture by abutting the knee against the knee abutment member 6. Next, the person to be assisted brings the upper body close to the upper body support member 41 to make surface contact, and holds the upper body by leaning the armpits against the armpit support member 47. At this time, the upper body supporting member 41 swings in the rising direction (the counterclockwise direction in fig. 1), and thus the forward tilting angle of the upper body can be small. Further, the underarm support member 47 is substantially horizontal or slightly lower at the rear, so that the assisted person can easily lean against the underarm support member 47.

Then, the assisting person pushes the up button of the operator to advance the assisting operation. When the actuator 5 performs the first stretching operation, the support member 4 swings forward. This operation is continued until the actuator 5 is extended to a predetermined intermediate length. At this time, the underarm support member 47 becomes lower at the front, so that the assisted person is restrained from moving backward without falling off from the support member 4.

Further, when the actuator 5 performs the second extension operation, the operating member 3 swings in the front-upper direction. This operation is continued until the end state in which the swing of the operating member 3 is restricted by the stopper mechanism. Thus, the auxiliary person takes a standing posture in which the buttocks rise greatly from the seating surface and the legs straighten.

4. Function of the angle adjusting part 8

Next, the operation of the angle adjuster 8 will be described in detail. Fig. 5 shows a state in which the assisted subject M1 having a standard body shape and having no large difference between the chest circumference K1 and the abdomen circumference H1 is prepared to receive assistance. The cushion 81 as the angle adjusting unit 8 is not required for the standard-sized auxiliary subject M1. As shown in the figure, when the abdomen of the standard-sized assisted subject M1 contacts the lower portion of the upper body support member 41, the separation distance L1 between the chest of the assisted subject M1 and the upper portion of the upper body support member 41 is small. Therefore, the auxiliary person M1 can support the upper body by leaning on the support member 4 only by slightly moving the upper body.

On the other hand, fig. 6 shows a state in which the assisted subject M2 of an obese body type having a relatively large girth H2 as compared with the girth K1 is prepared to receive assistance. The angle adjustment unit 8 should adjust the mounting angle of the support member 4 by using the pad 81 with respect to the fat-body-type assisted subject M2, but a case where the mounting angle is not adjusted (a case where the pad 81 is not used) is assumed here. In this case, when the abdomen of the fat-body-type assisted subject M2 contacts the lower portion of the upper body support member 41, the separation distance L2 between the chest of the assisted subject M2 and the upper portion of the upper body support member 41 is large. Therefore, the auxiliary subject M2 cannot approach the support member 4 without moving the upper body significantly, and is difficult to support the upper body. That is, the comfort of use at the time of the preparatory operation of the aided subject M2 is lowered.

As shown in fig. 7, a relatively large gap remains between the chest of the fat-body-type assisted subject M2 and the upper portion of the upper body support member 41 during the raising operation by the swinging motion (see arrow R1) of the support member 4 and the operating member 3. Therefore, the body pressure of the assisted subject M2 tends to concentrate on the abdomen. The abdomen of the assisted subject M2 is pressed by the lower portion of the upper body support member 41 (see arrow P1). That is, the comfort of use at the time of the standing operation of the assisted person M2 is reduced.

As shown in fig. 8, a relatively large gap remains between the chest of the fat-body-type assisted subject M2 and the upper portion of the upper body support member 41 during the sitting operation by the swinging movement (see arrow R2) of the support member 4 and the operating member 3 in the opposite direction. Therefore, the abdomen of the assisted person M2 is pressed so as to be sandwiched by the lower portion of the upper body support member 41. That is, the comfort of use at the time of the seating operation of the assisted subject M2 is reduced.

The above-described decrease in use comfort is caused by the angle adjusting part 8 not functioning properly. In the auxiliary device of the conventional structure without the angle adjusting unit 8, the standard-sized auxiliary subject M1 is assumed to define the mounting angle of the support member 4. Therefore, when the fat-body-type assisted device M2 is used as an assist device of a conventional structure, the above-described decrease in use comfort always occurs. Hereinafter, the operation of the angle adjuster 8 when properly operated will be described.

As shown in fig. 3 and 9, when the angle adjusting unit 8 functions properly, a pad 81 is used for the fat-body-type assisted subject M2. In other words, the angle adjustment unit 8 adjusts the support member 4 so as to approach the chest of the assisted subject M2. When the abdomen of the fat-body-type assisted subject M2 contacts the lower portion of the support member 4, the separation distance L3 between the chest of the assisted subject M2 and the upper portion of the upper body support member 41 becomes smaller or smaller than that of fig. 6. In detail, the separation distance L3 is smaller than the separation distance L2 of fig. 6 by approximately the thickness W of the spacer 81. Therefore, the assisting person M2 can lean against the support member 4 to support the upper body by slightly moving the upper body. That is, the comfort of use of the auxiliary machine M2 in the preparation operation is improved.

As shown in fig. 10, in the standing operation by the swinging movement (see arrow R1) of the support member 4 and the operating member 3, the gap between the chest of the fat-body-type assisted subject M2 and the upper portion of the upper body support member 41 becomes smaller or smaller than that in fig. 7. Therefore, the concentration of the body pressure of the assisted subject M2 to the abdomen is suppressed. The abdomen of the assisted subject M2 is restrained from being pressed from the lower portion of the upper body supporting member 41. That is, the comfort of use of the auxiliary machine M2 in the standing operation is improved.

As shown in fig. 11, in the seating operation by the swinging movement (see arrow R2) of the support member 4 and the operating member 3 in the opposite direction, the gap between the chest of the fat-body-type assisted subject M2 and the upper portion of the upper body support member 41 is still smaller or smaller than that in fig. 8. Therefore, the abdomen of the assisted person M2 is suppressed from being pressed by the lower portion of the upper body supporting member 41. That is, the comfort of use of the auxiliary subject M2 in the sitting operation is improved.

In the auxiliary device 1 of the first embodiment, the mounting angle of the support member 4 to the operating member 3 can be adjusted by the angle adjusting unit 8. Therefore, the mounting angle of the support member 4 can be adjusted so as to be suitable for the state of the upper body front surfaces of the plurality of the assisted persons (M1, M2), and the positional relationship between the assisted persons (M1, M2) and the support member 4 can be improved. Thus, each of the assisted persons (M1, M2) can feel good comfort in use. Therefore, the assist device 1 can ensure good comfort in use in accordance with various body types of the plurality of assisted persons (M1, M2).

5. The auxiliary device 1A of the second embodiment

Next, the auxiliary device 1A according to the second embodiment will be mainly described as being different from the first embodiment. As shown in fig. 12, the assist device 1A of the second embodiment includes a base 2A, a lifting member 3A and an arm member 3B which are operation members, a support member 4A, an angle adjusting unit 8A (see fig. 13), a control unit (not shown), and the like. The base 2A includes a foot rest 21, a pair of left and right rear wheels 23, and a pair of left and right front wheels 28, which are arranged parallel to the floor surface F. A strut 29 is provided between the front wheels 28 on the upper surface of the base 2A. A knee abutment member 6A is provided from the lower portion of the stay 29 toward the rear so as to be height-adjustable.

The lifting member 3A is provided on the rear surface of the support post 29, and is driven to lift by a linear motion device, not shown. An arm member 3B is provided at an upper portion of the rear side of the lifting member 3A. The arm member 3B swings in the front-upper direction and the rear-lower direction by being driven by a driving device not shown. The arm member 3B has a handle 46A, and the handle 46A is formed in a substantially quadrangular frame shape. The mounting position of the handle 46A can be adjusted. A swing support 33 is provided at the rear end of the arm member 3B.

The support member 4A having the upper body support member 41 and the pair of left and right armpit support members 47 is swingably attached to the swing support portion 33. As shown in fig. 13, the mounting angle of the support member 4A in the initial state is defined by the lower portion of the handle 46A. That is, the support member 4A swings downward around the swing support portion 33 by the action of its own weight and is stabilized at the attachment position abutting against the handle 46A. Therefore, the handle 46A doubles as an angle defining section for defining the attachment angle of the support member 4A. The present invention is not limited to this, and a dedicated angle defining unit may be provided.

The support member 4A can swing with respect to the arm member 3B within an operation angle range having the attachment angle as one end. Therefore, when the leg of the person to be assisted collides with the support member 4A from below, the support member 4A swings freely from the position of the illustrated mounting angle to the retracted position upward (see arrow R3 in fig. 13). Therefore, the leg of the assisted person is not sandwiched between the support member 4A and the base 2A.

The angle adjustment unit 8A adjusts the standard body type position of the handle 46A shown by a solid line in fig. 13 to the fat body type position shown by a broken line. Thereby, the mounting angle of the support member 4A approaches the standing direction. That is, the angle adjusting unit 8 adjusts the support member 4A so as to be away from the abdomen of the fat-body-type assisted subject M2. The angle adjustment unit 8A adjusts not only the mounting angle of the upper body support member 41 but also the mounting angle of the underarm support member 47. The angle adjustment portion 8A of the second embodiment functions in the same manner as the first embodiment described with reference to fig. 9 to 11.

6. Modification and application of the embodiment

The structure of the support members (4, 4A) can be deformed, and the shape and insertion position of the pad 81 can be changed according to the deformation. The angle adjustment sections (8, 8A) are not limited to the first and second embodiments. For example, the angle adjusting portion may be constituted by an angle adjusting mechanism using an actuator. The operation of the operating member 3 (including the lifting member 3A, the arm member 3B) and the supporting members (4, 4A) is not limited to the description, and may be, for example, a case in which the supporting members are simply moved up and down by the operating member. In addition, the present embodiment can be variously modified and applied.
