Description

Nursing device

Technical Field

The present disclosure relates to a care device for maintaining a stable state of an upper body of a care recipient.

Background

When a care-receiver such as a handicapped person or an elderly person cannot maintain a sitting posture by its own force when sitting on a sitting toilet (western toilet), for example, it is desirable to stabilize the upper body of the care-receiver. Therefore, Japanese Utility model publication No. 6-33919 (patent document 1) and Japanese patent application laid-open No. 2001 and 1699968 (patent document 2) disclose that an auxiliary device for stabilizing the upper body is provided around a sitting toilet.

The assisting device described in patent document 1 includes a pair of left and right tubes extending in the front-rear direction and positioned on the left and right sides of a care recipient seated on a toilet, and a curved grasping rod connecting the front end portions of the tubes to each other. Further, patent document 1 discloses a belt member for restraining the waist of a care recipient who sits on a toilet and rests the back on a backrest plate.

Patent document 2 discloses a technique in which a pair of left and right handrails, so-called handrails, extending in the front-rear direction and positioned on the left and right of a care recipient sitting on a toilet are provided so that the handrails can be swung in the up-down direction and a use position extending in the front-rear direction and a standby position extending in the up-down direction can be selectively obtained. Patent document 2 also discloses a belt member that is provided to restrain the upper half of the body of a care recipient who sits on a toilet and rests the back on a backrest plate.

SUMMERY OF THE UTILITY MODEL

Problem to be solved by utility model

The technical means described in the above patent documents are based on the assumption that the care recipient is a care recipient capable of performing an operation such as grasping an assist device, that is, a care recipient capable of exerting a force on arms or fingertips, unless a belt member for restraining the care recipient is used. However, some caregivers cannot perform an operation of gripping an auxiliary device or the like. In this case, since the sitting posture cannot be maintained by the force of the user, even if there is an auxiliary device that can be grasped around the user, the auxiliary device cannot be actually used.

Here, in the technique of patent document 2, the upper half of the care recipient is fixed to the backrest plate by using the belt member for the care recipient whose arm or finger tip cannot be forced. However, in actual circumstances, the restraint of the upper body by the belt member restrains the care-receiver, and the care-receiver is accompanied by a great mental pain and also causes ethical problems, and thus it is difficult to adopt.

In view of the above, an object of the present invention is to provide a nursing device that can reliably keep the upper body of a person to be nursed in a sitting posture stable without restraint by a belt member.

Means for solving the problems

In order to achieve the above object, embodiments of the present invention adopt the following solution. That is to say that the first and second electrodes,

the disclosed device is provided with:

a base member disposed in the vicinity of a seat on which a caregiver sits;

a support member which is connected to the base member via a swing connection mechanism so as to be capable of swinging in the vertical direction, and which has a support portion that is extended in the horizontal direction and that is configured to receive the front surface of the upper body of the care recipient seated on the seat portion; and

a swing angle changing mechanism for adjusting a swing angle of the support member with respect to the base member,

the swing angle changing mechanism includes:

a locking member provided on the base member and having a plurality of locking portions along a trajectory centered on a swing center of the support member;

an engaging member provided to be displaceable on the support member and capable of acquiring a locking position where the engaging member is locked to the locking portion and a retreat position where the engaging member retreats from the locking position;

a biasing unit provided on the support member and biasing the engaging member toward the locking position; and

an operating member provided on the support member and configured to displace the engaging member toward the to-be-retracted position against the urging unit,

the swing angle changing mechanism changes the swing angle of the support member by changing the locking portion of the plurality of locking portions, which locks the engaging member, thereby changing the height of the support member.

According to the above solution, the upper body of the care recipient, who is seated on the seat section and tilted forward, can be reliably supported by the support member. Further, by changing the swing angle of the swing angle changing mechanism, the support can be performed at an appropriate forward tilt angle desired by the caregiver. Of course, since the restraint is not performed by the belt member, the nursing person is not mentally painful and is not ethically problematic. In particular, when using a sitting toilet, the care-receiver can maintain a posture that is particularly favorable for promoting defecation by bending down, and since a large space is formed behind the upper half body of the care-receiver, it is preferable that the care-receiver easily performs a task of improving the performance such as cleaning the buttocks after defecation.

The solution proposed above is as follows.

The support member may include side frame portions located on sides of the person to be cared seated on the seat portion, and the support portion may be constituted by a front arm portion extending in a horizontal direction from a front end portion of the side frame portions and located in front of an upper body half of the person to be cared seated on the seat portion. In this case, the upper body of the care recipient in the seated posture can be prevented from falling forward by the front arm portion, and the upper body of the care recipient can be more stably supported by the side frame portions.

The portion of the support member near the swing connecting mechanism may be configured as a tube portion having a distal end opening, and the engaging member may be disposed in the tube portion and may protrude from the distal end opening at least when the engaging member is set to the locking position. In this case, the engaging member can be easily held by the pipe material.

The swing angle changing mechanism may be configured to change the engaging portion that engages with the engaging member regardless of an operation of the operating member when an external force swinging in a forward direction is applied to the support member. In this case, the operating member of the pivot angle changing mechanism cannot pivot unless it is operated in a direction toward the front suspension in which the user is not comfortable and the user can easily feel a sense of constraint, and the support member can be reliably prevented from excessively hanging down. In addition, regarding the swing in the forward direction of the support member, it is also permissible that the operating member of the swing angle changing mechanism is not operated, that is, the operating member of the swing angle changing mechanism is not operated, and the operating member can be easily swung from a not comfortable posture to a releasing direction, which is preferable in terms of releasing the restraining feeling. Particularly, in the case where the care-receiver is uncomfortable to maintain the stooped posture due to excessive forward tilting, the forward tilting angle is preferably set to a preferable forward tilting angle desired by the care-receiver.

The swing angle changing mechanism may be configured to allow the support member to swing in the forward-raising direction and swing in the forward-hanging direction only when the engagement of the engagement member by the engagement portion is released by operating the operation member. In this case, it is preferable that the swing in both the forward direction and the forward vertical direction of the support member is not performed unless the operation member of the swing angle changing mechanism is operated, and the swing angle of the support member is reliably maintained at a desired angle.

The plurality of engaging portions may be formed by a plurality of concave portions formed so as to sandwich the convex portion therebetween. In this case, the engaging portion can be simply constituted by the concave portion and the convex portion.

The plurality of convex portions may be inclined surfaces on a side surface of the plurality of concave portions, the side surface being a predetermined side surface in the arrangement direction of the plurality of concave portions, and the engaging member may be configured to ride over the convex portions along the inclined surfaces when an external force swinging in the forward direction is applied to the support member. In this case, the operating member of the pivot angle changing mechanism cannot pivot unless it is operated in a direction toward the front suspension in which the user is not comfortable and the user can easily feel a sense of constraint, and the support member can be reliably prevented from excessively hanging down. In addition, regarding the swing in the forward direction of the support member, it is also allowable that the operation member of the swing angle changing mechanism is not operated, that is, it is possible to easily swing from a not comfortable posture to a releasing direction without operating the operation member of the swing angle changing mechanism, and it is preferable in terms of releasing the feeling of constraint. Particularly, in the case where the care-receiver is uncomfortable to maintain the stooped posture due to excessive forward tilting, the forward tilting angle is preferably set to a preferable forward tilting angle desired by the care-receiver.

The plurality of locking portions may be a plurality of locking holes into which the distal end portions of the engaging members are inserted. In this case, the locking portion can be simply configured as a locking hole.

In the front end portion of the engaging member, a side surface of a predetermined one of the plurality of locking holes in the arrangement direction may be an inclined surface, and when an external force swinging in a forward direction is applied to the support member in a state where the front end portion of the engaging member is inserted into the locking hole, the engaging member may be disengaged from the locking hole while the inclined surface is along an inner peripheral edge portion of the locking hole. In this case, the operating member of the pivot angle changing mechanism cannot pivot unless it is operated in a direction toward the front suspension in which the user is not comfortable and the user can easily feel a sense of constraint, and the support member can be reliably prevented from excessively hanging down. In addition, regarding the swing in the forward direction of the support member, it is also allowable that the operation member of the swing angle changing mechanism is not operated, that is, it is possible to easily swing from a not comfortable posture to a releasing direction without operating the operation member of the swing angle changing mechanism, and it is preferable in terms of releasing the feeling of constraint. Particularly, in the case where the care-receiver is uncomfortable to maintain the stooped posture due to excessive forward tilting, the forward tilting angle is preferably set to a preferable forward tilting angle desired by the care-receiver.

The pair of left and right support members may be provided so as to sandwich the care recipient, and the pair of left and right support members may be coupled to each other by a coupling member located behind the care recipient and configured to swing integrally with each other. In this case, by coupling the pair of left and right support members to each other by the coupling member, the rigidity can be sufficiently improved as a whole, and it is preferable in terms of stably holding the upper body of the care recipient. In addition, the rearward fall of the care recipient can be prevented by the coupling member. In addition, only one of the left and right support members is swung, whereby the other support member can be swung in conjunction with the swing. In addition, the swing angle changing mechanism can be provided only for the left and right support members, and in this case, the operation of changing the swing angle is facilitated. In this case, it is preferable to firmly maintain a desired swing angle.

A cushion member that can be vertically swung can be attached to the support portion of the support member. In this case, it is preferable that the upper half of the body of the care-receiver in the sitting position can be flexibly received by the cushioning member, and the care-receiver is supported without giving pain or the like to the care-receiver. Further, the cushioning member supporting the upper body of the care recipient can be appropriately swung according to the change in the swing angle of the supporting member, the difference in the physique of the care recipient, or the like, and the care recipient can be supported in a preferred posture state of the cushioning member at all times.

The seat is provided on the toilet bowl, the base member has a pair of left and right vertical rod members extending in the vertical direction, and gap adjusting members for filling a gap between the seat and the toilet bowl are attached to the pair of left and right vertical rod members.

The pair of side frame portions are a pair of left and right frames, and the pair of left and right frames are slightly inclined so that the width therebetween is narrowed as the pair of side frame portions face upward.

Effect of the utility model

According to the embodiment of the present invention, the upper body of the care recipient in the sitting position can be stably supported reliably without restraint by the belt member. Further, the swing angle changing mechanism can support the upper body at a stooping angle desired by the caregiver.

Detailed Description

Fig. 1 to 3 show an example of a nursing device K according to an embodiment of the present invention. Fig. 1 to 3 show a state in which the nursing device K is disposed in the sitting toilet 1.

The nursing device K generally includes a base member 10, a pair of left and right side frame portions 20, a pair of left and right front arm portions 30, a rear frame portion 40, and a swing coupling mechanism 50. The side frame portions 20 and the front arm portion 30 constitute a support member.

The base member 10 has a pair of left and right vertical rod members 11 extending in the vertical direction, a horizontal rod member 12 extending in the horizontal direction and connecting upper end portions of the pair of left and right vertical rod members to each other, and a placement plate portion 13 connected to a lower end of the vertical rod member 11, and is generally gate-shaped. The rear part of the toilet seat 1 is disposed in a space below the pair of right and left vertical rod members 11 and the horizontal rod member 12. The base member 10 is a floor type that does not affect the structure of the toilet bowl 1, i.e., a flush valve or a low-level sink. The base member 10, more specifically, the mounting plate portion 13 of the base member 10 may be disposed in the vicinity of the seat toilet 1, and may be fixed to the seat toilet 1 or to the floor surface.

The side frame portions 20 are provided in a pair on the left and right sides, and are formed by bending a pipe material. The pipe material described below is composed of a core material made of metal such as SUS and a covering material made of synthetic resin, but is not limited thereto. Each side frame portion 20 generally includes an upper frame portion 21 extending in the front-rear direction and a lower frame portion 22 extending downward and then rearward from a front end of the upper frame portion 21. The rear end portion of the lower frame portion 22 is swingably attached to the vertical rod-like member 11 via a swing link mechanism 50 as described later.

The rear end portions of the upper frame portions 21 of the pair of left and right side frame portions 20 are connected to each other by a rear frame portion 40 extending in the left-right direction in a horizontal state. In the embodiment, the side frame portion 20 and the rear frame portion 40 are integrally formed of the same tube material. The left and right pair of side frame portions 20 are connected by the rear frame portion 40, so that the rigidity as a whole is improved, and by swinging one side frame portion 20, the other side frame portion 20 swings in conjunction therewith.

Referring also to fig. 4 and 5, the swing connecting mechanism 50 and the swing angle changing mechanism 60 related thereto will be described. First, the swing coupling mechanism 50 includes a coupling bracket 51 fixed to the vertical rod-shaped member 11 of the base portion 10. The side frame portions 20, more specifically, the rear end portions of the lower frame portions 22 of the side frame portions 20 are coupled to the coupling brackets 51 via coupling portions 52 so as to be swingable in the vertical direction. The coupling portion 52 is formed by an appropriate method such as a threaded coupling pin and a nut screwed thereto.

In order to constitute a swing stroke end of the side frame portion 20, a plate-shaped upper stopper portion 53 and a pin-shaped lower stopper portion 54 are formed on the connecting bracket 51. The stoppers 53 and 54 are set to form an angle of approximately 45 degrees around the coupling portion 52. The side frame portion 20 can swing about the connection portion 52, and thus the forward hanging angle (forward tilting angle) thereof can be changed. However, the rear end of the lower frame part 22 abuts against the upper and lower stopper parts 53 and 54, and the swing beyond the stopper parts 53 and 54 is restricted. Further, in a state where the lower frame portion 22 is in contact with the lower stopper portion 54, the upper frame portion 21 is in a basic posture state extending in the front-rear direction in a horizontal state.

The swing angle changing mechanism 60 for changing the swing angle of the side frame portion 20 is provided only in one side frame portion 20. As shown in fig. 4 and 5, the pivot angle changing mechanism 60 includes a locking member 61 integrated with the connecting bracket 51. The locking member 61 is made of metal such as SUS or synthetic resin, and is fixed to the connecting bracket 51 by a clamp 62.

The locking member 61 has an arc-shaped surface centered on the coupling portion 52, and a plurality of locking recesses 63 are formed at equal angles along the circumferential direction on the arc-shaped surface. The locking convex portions 64 are located between adjacent locking concave portions 63.

As shown in fig. 6 and 7, an engagement member 65 is slidably held in a rear end portion of the lower frame portion 22 of the side frame portion 20. The engaging member 65 has a plate-like main body portion 65a that slides on the inner surface of the lower frame portion 22, and an extending portion 65b that extends rearward from the main body portion 65a, i.e., toward the depth side of the lower frame portion 22. The extending portion 65b is formed with a long hole-shaped guide hole 65c extending in the sliding direction of the engaging member 65. An engagement protrusion 65d extending toward the locking member 61 is formed from the body portion 65 a. The engaging protrusion 65d can be fitted (engaged) and removed (disengaged) with respect to the engaging recess 63 by sliding of the engaging member 65.

A guide pin 66 penetrating the guide hole 65c is fixed to the lower frame portion 22. The engaging member 65 is displaceable within a range in which the guide pin 66 slides in the guide hole 65 c. Fig. 6 and 7 show a state of the engagement member 65 at the locking position where it protrudes most from the lower frame portion 22. The guide pin 66 penetrates the guide hole 65c substantially without rattling, and restricts the plate-like engaging member 65 from rotating in the circumferential direction of the lower frame portion 22.

A return spring 67 formed of a coil spring as an urging means is disposed in the lower frame portion 22. The return spring 67 is positioned between the guide pin 66 and the body portion 65a, and is disposed so as to wind the extended portion 65 b. The engaging member 65 is always biased by the return spring 67 in a direction of protruding from the lower frame portion 22, that is, in a direction of fitting into the locking recess 64.

An operation member 68 is slidably held in the vertical direction at a portion extending in the vertical direction in the lower frame portion 22. The operation member 68 includes a tube portion 68a slidably fitted to a portion extending in the vertical direction in the side frame portion 20, and an operation portion 68b integrated with the tube portion 68 a. The guide pin 69 integrated with the tube portion 68a is slidably fitted into a guide hole 70 formed in the side frame portion 20 and extending short in the vertical direction.

The guide pin 69 and the extension 65b of the engaging member 65 are connected by a connecting line 71 disposed in the lower frame portion 22. Thus, by gripping and sliding the operating portion 68b of the operating member 68 upward, the engaging member 65 can be displaced in the locking releasing direction in which it is drawn into the lower frame portion 22 against the return spring 67.

The upper side surface of the plurality of locking projections 64 is an inclined surface 64a that gradually faces downward toward the front end. On the other hand, the lower side surface of the locking projection 64 is formed in a shape that is inclined at a substantially right angle, and no inclined surface is formed.

Now, assume the following states: the side frame portion 20 is slightly in a state of hanging forward from the state of fig. 4 and 5, and the engagement protrusion 65d of the engagement member 65 is fitted into and engaged with the engagement recess 63. In this state, even if a large external force is applied to swing the side frame portion 20 in the direction in which it hangs forward, that is, in the counterclockwise direction in fig. 4 and 5, the swing is firmly restricted by the locking protrusion 64.

On the other hand, when a moderate external force is applied in order to swing the side frame portion 20 in the forward direction, that is, in the clockwise direction in fig. 4 and 5, the engagement projection 65d of the engagement member 65 can be made to ride over the locking projection 64 while following the inclined surface 64a of the locking projection 64. In this way, in the present embodiment, the swing in the front-vertical direction of the side frame portion 20 is strongly restricted, while the swing in the front-lift direction is allowed.

Next, the relationship between the side frame portion 20 and the front arm portion 30 will be described. First, the front arm portion 30 is formed in a substantially L shape by bending the pipe material. That is, the front arm portion 30 includes a main body portion 31 extending along the upper frame portion 21 of the side frame portion 20, and a support arm portion 32 extending by being bent at substantially 90 degrees from the main body portion 31. The front arm portions 30 are provided to the left and right side frame portions 20, respectively.

The main body 31 is swingably attached to the upper frame portion 21. Thus, the front arm portion 30 can selectively take a use position where the support arm portion 32 extends in the horizontal direction, that is, a position indicated by a solid line in fig. 1 and 2 and a retreat position where the tip end portion thereof faces upward, that is, a position indicated by a chain line in fig. 1 and 2. In addition, the swing of the front arm portion 30 at the standby position can be locked by a lock mechanism 90 described later.

From the viewpoint of versatility and the like, the distance between the pair of left and right vertical rod members 11 of the base member 10 is set to be sufficiently larger than the width of the seat toilet 1. Therefore, the pair of left and right side frame portions 20 are slightly inclined so as to gradually narrow in width as they go upward in the front view shown in fig. 1. Further, gap adjusting members 14 for filling the gap between the seat toilet 1 and the pair of right and left vertical rod members 11 are attached.

Here, the buffer member 80 is attached to the pair of right and left support arm portions 32 (see fig. 1 to 3). The mounting structure of the cushioning material 80 will be described with reference to fig. 8 to 10.

First, the cushion member 80 includes a substrate 81 made of, for example, an aluminum alloy or a synthetic resin, and an elastic member 82 integrated with the substrate 81 so as to cover one surface side thereof, and is, for example, a member having elasticity such as rubber or urethane. The base plate 81 has a curved portion 81a curved in an arc shape and a pair of flange portions 81b extending from respective ends of the curved portion 81 a. The substrate 81 can be formed by injection molding of synthetic resin, for example.

The bent portion 81a is bent to a size exceeding 180 degrees, and has an opening width smaller than the outer diameter of the support arm portion 32. The bent portion 81a is elastically deformed and fitted to the support arm portion 32 in a state where the opening width thereof is enlarged, whereby the cushion member 80 is attached to the support arm portion 32. The elastic member 82 of the shock-absorbing member 80 is disposed so as to face the care recipient P seated on the seat toilet 1.

The base plate 81 can swing by a predetermined angle with respect to the support arm portion 32. That is, the guide pin 83 formed of a bolt is fixed to the support arm portion 32, and a part of the guide pin 83 protrudes from the outer surface of the support arm portion 32. On the other hand, a guide hole 81c extending in the circumferential direction is formed in the inner surface of the curved portion 81a of the base plate 81. The guide pin 83 protrudes into the guide hole 81 c. The shock absorbing member 80 is swingable relative to the support arm portion 32 within a range in which the guide pin 83 is movable within the guide hole 81 c. In fig. 9, the cushioning member 80 in a state of being located at the swing stroke end is indicated by a two-dot chain line. Further, since the guide pin 83 protrudes into the guide hole 81c, the axial displacement of the shock-absorbing member 80 toward the support arm portion 32 is restricted.

The cushioning member 80 attached to the support arm portion 32, more specifically, the elastic member 82 of the cushioning member 80, is configured to be flexibly received by the upper body of the care recipient, thereby preventing pain or the like from being given to the care recipient. The cushion member 80 attached to the support arm portion 32 can be appropriately swung according to a change in the swing angle of the side frame portion 20, a difference in the physique of the care recipient, or the like, and the elastic member 82 can be always in a posture state favorable for support.

The cushion member 80 is also attached to the rear frame portion 40 in the same manner as the embodiment shown in fig. 8 and 9. The cushion member 80 attached to the rear frame portion 40 can swing in the vertical direction. When the care-receiver leans against the rear frame portion 40, the upper body of the care-receiver is flexibly received by the cushioning member 80 attached to the rear frame portion 40, and pain and the like to the care-receiver can be prevented. Further, the cushion member 80 attached to the rear frame portion 40 can be appropriately swung in accordance with a change in the angle of the rear frame portion 40, a difference in the physique of the person to be cared, or the like, and the elastic member 82 can be always in a posture state favorable for support.

Further, the cushion member 80 is also attached to the upper frame portion 21 of the side frame portions 20, more specifically, to a later-described coupling bracket 100 that is fitted to the upper frame portion 21 (see fig. 11 and 12). However, the cushion member 80 for the upper frame portion 21 is of a vertically fixed type. This allows the cushioning member 80 attached to the upper frame portion 21 to flexibly receive the caregiver when the caregiver falls over.

Next, with attention paid to the lock mechanism 90 for locking the front arm portion 30 at the retreat position, the attachment of the front arm portion 30 to the side frame portion 20 will be described with reference to fig. 11 to 14.

First, the rear end portion of the body 31 of the front arm 30 is constituted by the connecting member 33. The coupling member 33 is formed by, for example, extrusion-molding an aluminum alloy, and is fixed to the body portion 31 made of a pipe material by a jig 34 such as a bolt.

Fig. 11 and 12 show the cross-sectional shape of the coupling member 33. The coupling member 33 has a shape having a locking groove 33a and a first stopper portion 33b and a second stopper portion 33c each formed of a protrusion, as shown in the cross-sectional shape thereof.

The front arm portion 30, more specifically, the main body portion 31 of the front arm portion 30 and the side frame portion 20, more specifically, the upper frame portion 21 of the side frame portion 20 are coupled by the coupling bracket 100. That is, the connecting bracket 100 includes a first tubular portion 101 to which the body portion 31 of the front arm portion 30 is turnably fitted, and a second tubular portion 102 to which the upper frame portion 21 of the side frame portion 20 is fitted.

The coupling bracket 100 has a two-part structure of the first member 100A and the second member 100B in the second tube portion 102. Further, the two portions 100A and 100B are fastened by a bolt 103 and a nut 104 penetrating the upper frame portion 21. The upper frame portion 21 and the coupling bracket 100 are integrated by a bolt 103 and a nut 104.

The swing lever 110 is swingably attached to the connecting bracket 100 via a pin member 111. One end of the swing lever 110 is a locking claw portion 110a that can be fitted (locked) in the locking groove 33a of the connecting member 33. The swing lever 110 is biased by a spring 112 serving as biasing means in a direction in which the locking claw portion 110a is fitted into the locking groove 33 a. In the embodiment, the spring 112 is a plate spring and is interposed between the swing lever 110 and the coupling bracket 100.

The swing lever 110 has an operation portion 110 b. By operating the operating portion 110b clockwise in fig. 11, the engagement of the locking claw portion 110a with the locking groove 33a is released (unlocked).

A first stepped portion 101a and a second stepped portion 101b are formed at intervals in the circumferential direction on the inner surface of the first tube portion 101 of the coupling bracket 100. As shown in fig. 11, the position where the first stopper portion 33b of the coupling member 33 abuts against the first stepped portion 101a corresponds to the standby position. As shown in fig. 12, the position where the second stopper portion 33c of the coupling member 33 abuts against the second stepped portion 101b corresponds to the use position.

In order to change the front arm portion 30 from the standby position to the use position, the operation portion 110b of the swing lever 110 is operated to disengage the locking claw portion 110a from the locking groove 33a of the coupling member 33.

The front end surface of the locking claw portion 110a is a flat surface. A predetermined position on the outer peripheral surface of the coupling member 33 is a flat surface 33 d. In fig. 12 corresponding to the use position, the front end surface of the locking claw portion 110a is in a state of abutting against the flat surface 33d of the connecting member 33, and the front arm portion 30 is stably held at the use position. However, by applying an appropriate external force toward the retreat position to the front arm portion 30 located at the use position, the front arm portion 30 can be easily set to the retreat position.

The displacement of the coupling holder 110 relative to the coupling member 33 in the axial direction thereof is restricted. That is, although not shown, a regulating member that the side surface of the connecting bracket 10 abuts against is attached to the distal end portion of the connecting member 33, and the one end surface of the connecting member 110 is regulated from coming off from the connecting member 33. The other end surface of the connecting bracket 110 abuts against an end surface of the body 31 made of a pipe material.

Next, a method of using the nursing device K disposed in the sitting toilet 1 will be described. First, in a state before use, the front arm 30 is at the retreat position, that is, in a state shown by a chain line in fig. 1 and 2, and the front of the seat toilet 1 is widely opened. The side frame portion 20 is in a basic posture state not tilting forward, for example, a state shown in fig. 2. In this state, the care receiver P receives care of the caregiver and sits on the seat 1a of the sitting toilet 1.

After the care recipient P sits on the seat 1a, the front arm 30 is set to the use position. In the use position, the support arm portion 32 of the front arm portion 30, more specifically, the cushioning member 80 attached to the support arm portion 32 is positioned directly in front of the front portion of the upper body of the care recipient P (see fig. 3). Thus, when the upper body of the care recipient P falls forward, the care recipient P is supported by the front arms 30, and can be prevented from falling forward.

When the upper body of the care recipient P seated in the seat 1a falls backward, the upper body is supported by the rear frame section 40, and the upper body can be prevented from falling backward. In addition, the pair of left and right side frame portions 20 can prevent the caregiver P sitting on the seat portion 1a from falling sideways.

In order to promote defecation, particularly, defecation, the care recipient P is preferably greatly stooped. At this time, the caregiver may operate the operation member 68 to release the locking action of the swing angle changing mechanism 60, and tilt the side frame portions 20, and the front arm portion 30 and the rear frame portion 40 integrated therewith, forward to a desired tilt angle. After the desired forward tilt angle is achieved, the swing position of the side frame portion 20 is restricted by the operation of the release operation member 68.

Fig. 3 shows a state in which the side frame portions 20 are tilted forward by about 20 degrees from the basic posture state. The care recipient P is supported by the front arm 30 in a stooped state. The nursing care recipient P can be given a posture particularly advantageous for promoting defecation by bending the waist, and since a large space is formed behind the upper body of the nursing care recipient P, the nursing care recipient can easily perform a task of improving the condition such as cleaning the buttocks after defecation.

The front arm portion 30 located at the use position is not locked to the swing of the retreat position, and therefore the caregiver or the caregiver P having a free arm can smoothly set the front arm portion 30 to the retreat position. In particular, when the care recipient P can use the arms, it is preferable that the front arm section 30 can be smoothly swung to the standby position according to the intention of the care recipient P, and the feeling of constraint on the care recipient P is prevented or suppressed.

When the side frame portion 20 is tilted forward as shown in fig. 3, the caregiver P can rely on the rear frame portion 40 to his/her mind for the weight, and the engagement of the swing angle changing mechanism 60 is automatically released by the action of the inclined surface 64a of the engagement projection 64, and can move in a direction to reduce the forward tilt angle of the side frame portion 20, and can return to the basic posture state shown in fig. 2. The ability to easily reduce the forward tilt angle of the side frame portions 20 based on the mind of the care recipient P itself is also preferable in terms of preventing or suppressing the sense of restraint from being imparted to the care recipient P. Further, even in a case where the care recipient P maintains an uncomfortable stooping posture due to excessive forward tilting, the care recipient P can quickly return to the desired forward tilting angle.

After the defecation is finished, the side frame portion 20 is set to the basic posture state not tilting forward, that is, the state shown in fig. 2, and the front arm portion 30 is set to the standby position, for example, the state shown in fig. 1. Thereafter, the care-receiver P obtains care of the care-receiver, and leaves from the sitting toilet 1.

Fig. 15 shows a second embodiment of the present invention, and the same components as those of the above embodiment are denoted by the same reference numerals. This is also the same for the following third embodiment. This embodiment shows a modification of the swing angle changing mechanism. That is, in the pivot angle changing mechanism 60B of the present embodiment corresponding to the pivot angle changing mechanism 60 of the above embodiment, the engaging member 72 corresponding to the engaging member 65 of the above embodiment is cylindrical. The engaging member 72 is slidably fitted to the lower frame portion 22 via a cylindrical guide member 73.

The locking member 74 corresponding to the locking member 61 of the above embodiment is formed by forming a plate material into an arc shape. Locking holes 74a corresponding to the locking recesses 63 of the above embodiment are formed in the locking member 74 at equal angular intervals around the connection portion 52. The lower limit portion 54B corresponding to the pin-shaped lower limit portion 54 of the above embodiment is plate-shaped.

The lower surface of the engaging member 72 formed on the engaging projection 72a at the distal end is an inclined surface 72 b. The inclined surface 72b corresponds to the inclined surface 64a of the locking projection 64 of the above embodiment. That is, in a state where the engagement projection 72a is fitted (locked) in the locking hole 74a, the side frame portion 20 (the front arm portion 30) is firmly restricted from swinging in the forward vertical direction. On the other hand, when a moderate external force is applied to swing the side frame portion 20 (the front arm portion 30) in the forward direction, the inclined surface 72b can be disengaged from the locking hole 74a along the inner peripheral edge portion of the locking hole 74 a. That is, the swing in the forward direction is allowed.

Fig. 16 shows a third embodiment of the present invention, which is a modification of the second embodiment. In the present embodiment, the engaging protrusion 74a formed on the engaging member 72B (corresponding to 72) does not have the inclined surface 72B. Thereby, the side frame portions 20 are firmly locked in both the forward hanging direction and the forward raising direction. In both directions, the operation member 68 needs to be operated to release the locking.

Fig. 17 shows a fourth embodiment of the present invention. In the present embodiment, the base member 10D corresponding to the base member 10 is fixed to the wall surface located behind the seat toilet 1. That is, the base member 10D includes a pair of left and right mounting plate sections 121 serving as mounting sections to the wall surface, a pair of left and right rod-shaped members 122 extending forward from the respective mounting plate sections 121, and a connecting rod-shaped member 123 connecting front end portions of the pair of left and right rod-shaped members 122 to each other. In the present embodiment, each of the cushion members 80 is of a fixed type that does not swing. Fig. 17 schematically shows a portion where the bracket 100 is coupled. The operating lever of the lock mechanism 90 is not shown.

Fig. 18 shows a fifth embodiment of the present invention. In the present embodiment, the base member 10E is substantially formed by the mounting plate portion 131 fixed to the wall surface located behind the seat toilet 1. The support member including the side frame portion 20 and the front arm portion 30 is disposed only on the left side of the care recipient. The support member having a shape bilaterally symmetrical to the structure shown in fig. 18 may be provided only on the right side, and a pair of left and right support members may be provided independently.

The above embodiments have been described, but the present invention is not limited to the embodiments, and can be modified as appropriate within the scope of the claims. The front arm portion 30 may be configured to swing about an axis extending in the vertical direction, more specifically, in the horizontal plane, thereby changing the position between the use position and the standby position. In terms of the carer or the care receiver being able to use the front arm 30 at the standby position as the balustrade, it is preferable that the front arm 30 at the standby position takes a posture state extending in the up-down direction or a posture state extending in the horizontal direction toward, for example, the front or outer side of the seat, and locks the front arm 30 at the standby position. The front arm portion 30 may be provided only on one of the pair of left and right side frame portions 20 of the side frame portion 20. At least one of the cushion members 80 provided on the support arm portions 32 or the rear frame portion 40 may be of a non-swing fixed type, or may be of a shape covering the entire circumference of the support arm portions 32 or the rear frame portion 40.

In order to improve the convenience of locking and unlocking, the swing angle changing mechanism 60 may be provided only in one of the pair of left and right side frame portions 20, and may be provided in both of the side frame portions 20 in order to ensure a more reliable locking action. Instead of providing the pair of left and right side frame portions 20, only one of the left and right side frame portions may be provided. The front arm 30 may be fixed at the use position all the time. In the present embodiment, the number of the rocking angles that can be obtained by the support member between the rocking stroke ends thereof is set to be plural in a stepwise manner, but may be changed to a continuously variable type.

The side frame portion 20 and the rear frame portion 40 can have an appropriate structure, and can be configured to have a surface (formed in a planar shape), for example. When the forming surface is formed, the forming surface may be formed of only a plate material, or may be formed of a combination of a plate material and a pipe material. As the plate material to be used, a metal plate or a plastic plate, in particular, a fiber-reinforced plastic plate or a porous plate can be used.

The device having the seat to which the present invention is applied is not limited to a sitting toilet, and includes, for example, a suitable device such as a stationary chair for rest or a stationary chair located at a viewing position. The swing coupling mechanism 50 is not limited to the embodiment, and an appropriate structure can be selected, and similarly, the swing angle changing mechanism 60 and the lock mechanism 90 are not limited to the embodiment, and an appropriate structure can be selected. Of course, the objects of the present invention are not limited to those explicitly described, but rather implicitly provide substantially preferred or advantageous results.
