Abstract

PROBLEM TO BE SOLVED: To provide a bathroom that an auxiliary nursing care instrument can be easily installed therein which assists a care giver who helps a care receiver with the movements of standing up and sitting, and which does not need external power and is light and safe.SOLUTION: A nursing care instrument suitable for bathing applies a movable pulley principle, and fixing members (5e, 5f) are appropriately disposed in areas of a bathroom which are not over the heads of a care receiver and a care giver. The nursing care instrument allows the care giver to easily apply force to the care receiver in a natural position and therefore to care the care receiver in a comfortable position by stamping on a force point member (stirrup member 5p) and using frictional force on a rope. A supporting member (annular harness 5h) for suspending and supporting the care receiver by the hip joints or armpits does not inflict pain on the care receiver, does not become obstructive at the time of bathing or the like, and is devised so as to be a sanitary one. Anchor members for installing the fixing members are provided at appropriate positions of the bathroom in advance.

Description

  TECHNICAL FIELD The present invention relates to an auxiliary care tool for assisting a care recipient who has deteriorated athletic ability, in particular, the ability to exercise the lower limbs, and a caregiver who assists in standing and sitting, and a bathroom that facilitates attachment of the care tool. is there.

As a typical example of exercise that is difficult for those who have difficulty in exercising their lower limbs, standing up from the sitting position, raising the body from the supine or lying position, and conversely sitting from the standing position The seating action can be raised.
When a caregiver who assists these actions performs a support action, in many cases, the caregiver is in an unstable posture of bending forward and is in a state where it is difficult to apply sufficient force. In addition, when the caregiver is an elderly spouse, etc., is it difficult for the caregiver to take the unstable posture described above or to exert sufficient power in the unstable posture? In many cases, it is practically impossible, and the carelessness of the caregiver's legs may be impaired due to an unreasonable posture.
Most typically, there is an operation in which a person who can move several times with a decrease in athletic ability, in particular, athletic ability of the lower limbs, stands up after taking a bath in a sitting position. In many bathrooms, the bottom of the bathtub is at the same height as or below the bathroom floor, so that the caregiver can lean forward when the caregiver is unable to stand on his own. Becomes even more difficult. If you step into the bathtub, the caregiver's posture should be somewhat more stable and easier to apply, but it usually does not take that drastic action. In a bathroom where the floor is wet and slippery, the caregiver's feet become more unstable, increasing the difficulty of assisting.

The following are disclosed as tools and equipment for assisting the walking and bathing movements of people with reduced physical exercise ability, as well as nursing tools and techniques for assisting the caregiver's support movements. .

  For example, Patent Document 1 and Japanese Patent Application Laid-Open No. 2009-006093 disclose a motor-driven liftable chair, which incorporates an electric mechanism in a bathroom with high humidity. There is a problem in safety during operation. In addition, as is clear from FIG. 5 of Patent Document 1, in order to fix a supporting column having sufficient strength, it is essential to reinforce foundation work such as a bathroom, and FRP when considering the installation area estimated from the drawing. Retrofitting into a general bathroom such as a unit bath was difficult.

In Patent Document 2, paragraphs 79 to 83 of Japanese Patent Application Laid-Open No. 2006-28869 and FIG. 14, a single-action cable fixed to an opposing wall surface (Patent Document 2, 71 in FIG. 14) parallel to the longitudinal direction of the bathtub in the bathroom. Rodless cylinder (Patent Document 2, 60 in FIG. 14) serves as a power source for moving the cared person in the vertical direction via the moving pulley, and is fixed to the vicinity of the ceiling so as to stretch against the opposing wall surface. In addition, a nursing care device is disclosed in which a magnetic rodless cylinder (Patent Document 2, 20 in FIG. 14) serves as a power source for moving the care recipient in the horizontal direction. The magnet type rodless cylinder has a horizontal carrier (Patent Document 2, 82 in FIG. 14) integrated with two movable fixed pulleys that change the direction of the rope (Patent Document 2, FIG. 14, 55). Since it is moved in the direction, it is possible to assist the care recipient to move left and right.
Problem A: A power motor is not required, but a special external power member such as a hydraulic cylinder is required.
In FIG. 14, the left end of the rope is fixed to the end of the magnet type rodless cylinder and stretched almost horizontally, and the direction is changed substantially vertically downward by a fixed pulley integrated with the carrier. 2, chair lift-like member in FIG. 14, no symbol in the figure) Turn about 180 degrees with the upper moving pulley and hit another fixed pulley built into the carrier. With this latter fixed pulley, the direction is changed to about 90 degrees to the right again, and it is bent vertically downward by a fixed pulley (Patent Document 2, 75 in FIG. 14) attached to the right end of the magnet type rodless cylinder. It is connected to a single-action rope-type rodless cylinder that is a power source for raising and lowering. As shown in the figure, there are 5 pulleys in total, and the number of parts that can be read from the figure such as ropes, rodless cylinders, fixtures etc. is about 10 points (total 15 points, 2 rodless cylinders are 2 points as modules) Is used). The weight of these mechanisms is estimated to be about 50 kg (including 15 liters of water to be filled in the cylinder) from the size estimated from the figure. More than 100kg. Since it is difficult to support it with only the frictional force due to adhesion and stretching to the left and right wall surfaces (substantially impossible with FRP unit bath), the rodless cylinder is supported by a column in paragraph 82 to compensate for the strength on the left wall surface. Although it suggests a contrivance, it should have a support column that prevents the bathtub from collapsing in the longitudinal direction of the bathtub. The overall weight and installation area are large, and the installation work associated with it is large. Construction seems possible, but there are still about 50 kg of machinery on the head of the care recipient and caregiver, which is not desirable for safety.
Problem B: Large number of parts, large installation area, and large amount of reinforcement work.
Problem C: A heavy mechanical device is overhead, which is not preferable for safety.
As a basic design for nursing care, when used by a person who is capable of “holding or moving a few steps on their own” as assumed in the present invention, the nursing care mechanism in the center of the bathtub shown in the figure is It is difficult for the caregiver to support the posture of the cared person who shakes in an unstable manner, and if he sits as it is, he can sit on the center of the bathtub and cannot lean against his back. Estimating the dimensions of the machinery and the installation work space, in this case, it is estimated to be 40 cm from the wall surface, but I would like to make it a little closer for the care recipient to touch the wall.
Problem D: A device that simplifies the structure so that the body of the cared person is located near the end of the bathtub and that the body is well controlled and easily supported by the carer, and that the equipment and tools need to be downsized. .
Problem E: It is necessary to devise a hanger for a cared person who can hold and stand by himself.
In Patent Document 2, the caregiver's role is to gently move the cared person on the carrier from the washing place toward the bathtub and move left and right (Patent Document 2, paragraph 70), The remote control-like push button type switching valve is used to control the up / down / left / right movement of the carrier (Patent Document 2, Paragraph 83).

Patent Document 3, Japanese Patent Application Laid-Open No. 2002-000671, paragraph 31 and FIG. 8 include a device that assists a person to be cared for in the care-requiring state category 2-3 and assists getting up and walking, and a “hanging tool”. A harness-shaped loading sheet (A to C in FIG. 5) is disclosed. Also in the disclosure of this document, a solid rail crane mechanism and a motor drive mechanism are required on the ceiling or the like (Problems A, B, C), and a device (Problem D) for suppressing shaking of the cared person's body. The rest will depend on the caregiver's efforts. In addition, the harness-shaped loading sheet is suspended by 4 to 6 ropes so that the cared person can become independent without the help of the caregiver. It is expected to be difficult to use even if applied. That means
Problem E1: 4-6 ropes around the body are likely to obstruct the face when washing the face, etc.
Issue E2: The crotch that you want to clean clean is covered with a saddle-shaped loading sheet and is difficult to wash.
These are issues.

Patent Document 4 and Japanese Unexamined Patent Application Publication No. 2009-17922 disclose a walking support device that does not require a power source such as a motor. Paragraph 23 and FIGS. 1A and 1B of this document show an unloading structure that stably holds a cared person by suspending a cared person statically with a combination of a rope and a fixed pulley. This is consistent with the basic premise of the present invention in that a part of the body weight is supported by a rope and the rest is supported by the cared person's own foot. However, the place where the cared person is stably fixed in this support device in a standing position is the starting point of the technology of this document that supports walking training, and the device for raising the posture from the sitting position to there is not disclosed. Application to standing up or sitting at the time of bathing, and problems and solutions for that purpose are not shown.
The walking support device includes four regular pulleys (Patent Document 4, FIGS. 1A and 1B, symbols 103a and 103b). Here, the body of the cared person moves left and right inside the frame (same as symbol 300). Because there is no need to do this, the pulley is fixedly attached to the frame. Do not use a moving pulley. Weight-carrying device main body composed of elastic members such as ropes and springs provided with the body of a cared person during walking training who will lose their balance and are likely to fall (Patent Document 4, FIGS. 1A and 1B) Support with the symbol 210).
In other respects, the harness disclosed in Patent Document 4 extends from the cared person's hip joints to the vicinity of both shoulders on the left and right and front and back of the body, and 4 to 6 around the body during bathing. The previous problem E1 due to the presence of the rope is not solved.
In addition, since the harness can be worn separately at the left and right hip joints, the problem E2 of Patent Document 3 is solved, but the corset-like belt for holding the cared person's body firmly covers the upper body, so it is an obstacle when taking a bath It seems that improvement is necessary.
Note that the role of the caregiver in Patent Document 4 is to provide support (burden) to the extent that the care recipient is about to fall over when the cared person is about to fall. It can be understood that it does not actively use the power of care and support, and has sufficient capacity (Patent Document 4, paragraphs 2 and 3, etc.).

In addition, we investigated the bathroom in the range of existing products, but while designing the bathroom, some ideas and mechanisms for attaching things like rails and robot arms around the bathtub have been proposed. In the sense of preparing for future care in a separate general household bathroom, there are only handrails and easy-to-use chairs. Such basic ideas and mechanisms are very important, but other ideas to support and assist the caregiver in moving to a chair or bathtub that is easy to use while holding on to the handrail are sufficiently provided. I found out.
In reality, it is impossible to predict and prepare for the care issues that each family will face in the future, and it is impossible to expect even at the design stage when purchasing a home. It is impossible to design and construct the foundation structure for ceiling rails and robot arms that cannot be determined in advance, and in addition to cost problems, preparations for the installation of nursing care equipment for the future are almost made. Not. But if you can choose a simple, reliable, and inexpensive setup, many homes should have minimal preparations for the future.

The problem to be solved by the present invention is to provide an auxiliary care device for assisting a cared person whose athletic ability, particularly the ability to exercise the lower limbs, and a caregiver helping to stand and sit, and It is intended to provide a bathroom in which additional work for attaching such auxiliary care devices can be minimized or almost eliminated. As used herein, “a care recipient whose ability to exercise lower limbs” means a person who can walk and stand for several steps. (The device of the present invention cannot assist standing or sitting of a cared person who cannot maintain a standing position at all, and would like to make it possible by future improvement.)
Problem A, more specifically, the present invention is such that when the cared person is difficult to stand up or sit in the bathtub, the carer provides the force to assist the operation, and the upper body is likely to shake and become unstable. Make it possible to support the cared person at the same time. It is often difficult for caregivers to handle machines and electric motors in elderly couples' homes, etc. The most important issue is to provide tools that can provide care without using such external power at all. did.
Issue B, to minimize the number of parts, small installation area, and minimum installation work by devising as simple a mechanism as possible. The smaller the number of parts, the safer and more safe operation is possible for caregivers and caregivers, and maintenance is possible, which is very basic, and there is no need to explain much about the installation area and the amount of construction. . The small installation area is the basis for organizing and maintaining safe indoor care by keeping the indoor space wide. If the installation work is simple, it is easy to change or remodel nursing equipment according to the recovery of the health status of the care recipient. It also leads to things.
Issue C, to realize the fundamental safety in case of a fall, etc., taking into consideration that there are no heavy objects, bulky parts, sharp parts, etc. above the care recipient and caregiver. When it is absolutely necessary to place it above the head, we will try to select a light, round shape with few corners.
Problem D: As a basic design, the place to support the cared person's body with a pulley or a rope is close to the end, not the middle in the longitudinal direction of the bathtub. The body of a cared person with weak lower limbs swings back and forth, left and right, and when trying to solve it with external power and a fully-suspended care tool such as a chair lift, it must be dimensionally as large as in the bathtub. Add some ingenuity to it.
Problem E: A support member (harness) that supports the weight of the cared person is devised, comfortable for the cared person, not tied up or tightened, and the support member does not cling around the body during bathing. It is especially easy to wash the crotch that you want to clean. In addition, it is easy for the care receiver to attach and detach the support member, and it is easy to connect to the suspension member.
In the present invention,
The overall problem is to provide an auxiliary care device that solves the specific individual problems A to E as described above, and to provide a bathroom having a structure in which such a care device can be easily attached in the future.

In order to solve the above-mentioned problem, the care device according to the present invention is a supplementary care device that assists a care recipient who has lost the physical ability of the body including the lower limbs and a caregiver who assists the standing or sitting operation of the care recipient.
1. A rope-shaped member that conveys the caregiver's power to help the movement;
2. A first fixing member that fixes one end without changing the direction of the rope-shaped member;
3. While being in contact with the rope-like member and changing the direction of the rope-like member, the subject can be slidable or rotated relative to the rope-like member, and moved vertically with the cared person's body in the vertical direction. A suspension member that supports the suspension of a part of the person's weight,
4). A support member connected to the suspension member and supporting the body of the cared person by supporting a part of the weight of the cared person;
5. While being in contact with the rope-like member and changing the direction of the rope-like member, it can slide or rotate relative to the rope-like member, but its own center of gravity moves with the body of the care recipient. A second fixing member that is fixed in the room,
6). Attached near the other end of the rope-shaped member, the caregiver
A force point member for applying a force to help the cared person to stand and sit;
It is characterized by comprising.
The “caregiver's force” as used in the present invention mainly means a force for helping to move the cared person's weight in the vertical direction, that is, a force for helping to stand and sit.
In addition, “first fixing member”, “suspending member”, “second fixing member”, etc. do not mean only one piece of hardware that the rope contacts, but a flexible and strong relay rope attached to the rope, It also includes a series of member combinations such as a three-piece set of ring-shaped hardware that connects the relay rope and the rope-like member.

The disclosed technology of the part referred to in Patent Documents 1 to 3 shown in the background art column is that the cared person has little or no exercise ability to walk and maintain his / her standing posture. However, the care recipient is assumed to be passive, and the problem extraction and the contrivance of the solution are started. However, in the present invention, such an athletic ability of the care recipient is weakly maintained but utilized. Assuming that. If you have enough walking skills, walking slowly with a cane or walker, or having the ability to hold a standing posture for a short time by grabbing a handrail, the caregiver will be able to take advantage of that power. By devising a mechanism that helps the caregiver to stand and sit, the auxiliary care device can be greatly simplified and reduced in weight.
The inventor is caring for an elderly person whose physical ability has actually declined, and the caregiver / caregiver has the most physical burden when the caregiver is standing or sitting in a low position close to the sitting position. We paid attention to the fact that it is difficult to operate. This can be easily simulated by healthy young people, but it is very difficult to stand up from a sitting position with only one foot, but once standing, it is easy to maintain standing with one foot. Therefore, we decided to resolve the low posture close to the sitting position preferentially, and from the middle waist to the standing position, it was possible to provide sufficient care with little force, so we decided to consider it as a margin to reduce the priority and increase the freedom of design.
In order to support standing or sitting without external power, the caregiver must continue to exert a force of several tens of kilograms corresponding to the weight of the cared person for a certain period of time. Since it is impossible for the upper limbs such as arms, it is reasonable to exert it on the lower limbs, and it is sufficient to include a device that uses the “stepping force with feet” that can use natural gravity.
Furthermore, in many cases, the elderly man's physical strength is weak and his wife cares overwhelmingly. A force mechanism is also required.

Based on this idea, in the present invention, the basic structure was examined based on the principle of pulleys and simple trigonometric calculation.
By using a moving pulley, a caregiver with a weight of 40 kg can ideally balance with a caregiver of 80 kg (Fig. 1). However, the principle of the moving pulley where the rope hangs straight, the cared person and the caregiver must stand side by side, and there are three pulley members near the head of the two people, and I want to change the position for safety Moreover, since the two fulcrums are close to each other, the load is concentrated on one place on the wall surface, so that the arrangement is desired to be distributed. Therefore, when the fulcrum (hereinafter also referred to as a fixed member) such as a fixed pulley is moved left and right (FIG. 2a), it is assumed that it is the upper part near the bathtub corner. In an average bathroom, the short side of the bathtub is 80cm, the difference between the height of the bathroom / bath bottom is 15cm, and the ceiling height of the bathroom is about 220cm. Assuming that the height of the cared person is 170 cm, the sitting height is 85 cm, and the carer's weight is 40 kg,
Trial Calculation 1 (Fig. 2a): When the fixing member is fixed near the ceiling, the distance from the head to the fulcrum is 150cm in the sitting position in the bathtub, so the rope opening angle at the point of action (hereinafter also referred to as the hanging member) is 2theta_1 = 2 * tan ^ -1 (40/150), where cos (theta_1) = 0.97. In other words, the efficiency of the force in the vertical direction by moving the fixed point left and right, such as a fixed pulley, can maintain a sufficiently high value of 97% (loss 3%, ignoring losses such as friction here), and 40kg Even a caregiver can help a 2 * 40 * 0.97 = 77kg cared person to stand. For reference, the V-shaped opening angle of the rope is about 2 * 15 = 30 degrees.
Actually, the cared person is sitting in the bathtub at this time, so buoyancy is helpful, and the real upper limit weight is over 77kg. In other words, the practical margin is large.
Trial calculation 2 (Fig. 2b): Similarly, in the standing position in the bathtub, it is 65cm from the head to the fulcrum, so the rope opening angle at the point of action is about 2theta_2 = 2 * tan ^ -1 (40/65). theta_2) = 0.85. In other words, even if the cared person stands up and the V-shaped opening angle of the rope increases, the efficiency of 85% can be maintained. Even if the cared person suddenly loses balance in the standing position, if the weight is 2 * 40 * 0.85 = 68kg, the weight of the caregiver of 40kg can be balanced. If the balance is not lost, the cared person stands almost with his / her own power, and the carer is able to allocate sufficient remaining power for care operations other than standing up and sitting support. For reference, the V-shaped opening angle of the rope at this time is about 2 * 32 = 64 degrees.
Since the mounting height of the fixing member uses a pulley, the height of the fixing member is at least higher than the height of the cared person, and ideally close to the ceiling. Generally, it is about 190 to 220cm above the bathroom floor. It is desirable to make it as high as possible in the sense of reducing the caregiver's power loss.

Furthermore, the care device of the present invention is particularly effective when applied to a bathroom where the care recipient's sitting posture is low. In that case, the place where the fixing member of the auxiliary care device is attached is at both ends of at least one short side of the two short sides of the rectangle when the bathtub in the bathroom is viewed in plan and has a substantially rectangular outer shape. It is preferable that the first fixing member and the second fixing member are fixed upward. In the present invention, the relative positions of the two fixing members may be such that the first fixing member is at the back of the bathroom and the second fixing member is at the center of the bathroom. If the 2nd fixing member is made into the bathroom center side, it will be easy to ensure the attachment place of the power point member which a caregiver applies force in the downward direction, and the operation place of a power point member.
In addition, the first fixing member has one end (starting end) that always stops and supports the end of the rope-like member, that is, it is only required to be stable toward the cared person's body. There is no need to change the direction of the member.
The second fixing member is in contact with the rope-shaped member, and the direction of the rope-shaped member is changed from the direction of the cared person's body to the power point member, and the rope-shaped member is used in order to minimize the transmission loss of the caregiver's force. Although it moves so as to slide or rotate relatively, it functions as a fulcrum, so that the center of gravity of the second fixing member itself is fixed in the room without moving with the body of the cared person. A pulley or a carabiner is suitable for the second fixing member that is actually used.
These configurations lead to solutions for issues A and C.

When the mounting positions of the first fixing member and the second fixing member of the present invention are viewed in the long side direction of the bathtub, they are not positioned near the center but are fixed at positions along the same wall surface near the end. In this way, the first fixing member on the back side of the bathtub is attached near the corner where the strength of the two surfaces of the wall and the ceiling surface is high, and the second fixing member on the center side of the bathroom is attached on the wall surface. . Since it is easy to devise construction that presses and fixes a fixing member to a corner or a wall surface, it is convenient for stably fixing and maintaining the fixing member, and at the same time, the construction work for reinforcement is reduced.

More importantly, by taking this arrangement, a fixed member such as a fixed pulley is moved to the end in the long side of the bathtub, and if this position is matched with the body being placed during normal bathing, care will be taken The person who sits in the sitting position will be in a position that is easy to lean against the bathtub, and in the standing position, the bathroom wall and the back of the cared person are close to each other. Will support you. That is, the caregiver does not have to worry about the caregiver falling to the back side. As described above, it is preferable for the care operation that the fixing member is fixed at a position along the same wall surface in the room, and it becomes more rational by approaching the end in the long side direction of the bathtub.
“Position along the same wall surface” means that it is close to the same wall surface among the walls surrounding the room, but the proximity distance is 0cm that is in contact or about 15cm that is slightly lifted away If it is in the distance. That is, it is not necessary that the fixing member is always in contact with or in close contact with the same wall surface.
This leads to solving the problems D and B.

  At least one of the first fixing member and the second fixing member may be fixed by an auxiliary support post retrofitted in the room. Each fixing member must secure sufficient mounting strength to support the weight of the cared person, but in the case of a general FRP unit bath etc., it may be difficult to ensure strength only by drilling and screwing. . Also, it is difficult to drill holes while minimizing damage to the wall surface in tiled burrs and mortar-finished bathrooms. Therefore, it is not only effective to fix with the auxiliary struts, but when the caregiver's lower limb motor function recovers in the future and the auxiliary care equipment becomes unnecessary, it will be removed cleanly with minimal scars remaining in the room. can do.

The auxiliary strut may be divided and / or foldable in the longitudinal direction. This is because the members can be easily transported, assembled and disassembled. Auxiliary struts can be over 2m in size, but the general situation is that the bathroom and its entrance are often narrow or bent. In addition, when existing handrails or water pipes are fixedly installed in the vicinity of the bathtub, there is a possibility of interference in dimension during the installation work of the auxiliary column. Furthermore, when the care device according to the present invention is used in visiting care, it must be easily transported by car. Considering these things, it is desirable that the auxiliary struts are divided, folded, or a combination thereof in the longitudinal direction, and can be reduced to about 1 m or less at the stage until assembly work.
The relay member for splitting and folding does not require a large external force, so there is no need for a particularly sturdy hardware, batten or splint. As can be seen in the examples shown later, the main force applied to the auxiliary strut is the compression force parallel to the longitudinal direction, not the right angle (lateral) direction where the tensile force or shearing force acts. Simple hardware can be used.
The auxiliary strut material that can be shortened by splitting and folding can be roughly 1 m or less, and splitting and folding can be realized in two splits or two steps (one turn). If necessary, the structure may be divided into three parts or three steps (two folds), or a combination of division and folding may be used.

The auxiliary strut may have a telescopic mechanism in the longitudinal direction and the length can be adjusted. As a result, the length of the auxiliary strut is standardized at a typical length, and during individual installation work, differences in length can be adjusted at the installation site, making the work easier, and at the same time It helps to stabilize quality because it is easy to keep the work level for each construction above a certain level. Furthermore, standardizing the length of the auxiliary struts will lead to a reduction in member costs.

The support member works to suspend a part of the weight of the cared person, but at that time, the hip part that is lower than the cared person's waist and the lower part of the shoulder joint touch the cared person's body. good.
The hip joint is the strongest of all human joints, and is located close to the center of gravity of the human body, so if the support member supports the hip joint, even if it is a cared person with weak physical strength, there is no pain to the cared person Moreover, it becomes possible to support weight stably. When a support member is applied to the hip joint, the support member remains applied even after sitting in the bathtub, but since the crotch is not covered, the original purpose of bathing for cleansing the body is not hindered.
The support member may be attached to support the heel portion. Since the heel portion, that is, the shoulder joint is also sufficiently strong and located at a position higher than the center of gravity of the person, it is possible to stably support the cared person's body without pain. Compared to the case where the support member supports the hip joint, when the cared person himself / herself holds the support member with his / her hand, this is a natural posture, and the cared person has a sense of security. I can do it. After sitting in the bathtub, it is easy to temporarily remove the support member from the tub or turn it again into the tub, so it is possible to devise a method that does not hinder bathing at all.
Compared with the case where a support member is applied to the hip joint, the configuration that supports the heel portion is suitable when the physical strength of the cared person remains stronger. On the other hand, if the exercise ability to maintain the physical strength and posture of the cared person is very weak, it is also effective to support both the hip joint and the heel with the support member. Can support cared people who tend to be unstable in posture more stably and without pain.

Ideally, the support member is previously attached to the body of the care recipient. As a result of various trial manufactures taking into consideration ease of wearing and ease of washing, etc., two belt towels with a width of about 10 to 40 cm or soft nylon material were sewed in a thigh or under the heel. It is good to put it in between. The length of the ring is adjusted appropriately according to the physique of the cared person, but the circumference is preferably 90 to 180 cm. When assuming support for hip joints, it is about the height of the cared person, and about half when assuming support for the heel. Such a member is called an annular harness in the present invention.
In the present invention, since the two annular harnesses are worn so as to be worn on both legs of the cared person or sandwiched between the two legs, the crotch is not covered and it becomes easy to wash such a part when taking a bath. ,convenient.
A part of the annular harness is connected to the suspension member to suspend part of the weight of the cared person, but in order to quickly and reliably perform the operation of connecting to the suspension member, It is advisable to wear a ring of similar rope material (FIGS. 3a and 3b). Alternatively, a method of attaching a ring of connecting ropes to the suspension member may be used, and a method that can be easily handled by a caregiver may be selected as appropriate.
Thus, the problem E can be solved.

The suspension member is in contact with the rope-like member so as to slide or hook, and changes the direction of the rope-like member from the first fixing member toward the second fixing member. And, in order to minimize the transmission loss of the caregiver's force, it moves so as to slide or rotate relative to the rope-like member, but it functions as an action point, so the center of gravity of the suspension member itself is Moves vertically with the person's body. A part of the weight of the cared person is supported so as to be suspended, and the remaining weight is supported by the cared person's own foot. As the hanging member to be actually used, a member such as a C-shaped ring or a hook-shaped hardware that allows easy removal of the supporting member as described above is appropriately selected, but the most suitable one is a carabiner. This is because the carabiner is originally made of materials, structure, and finish so that it can be operated by hand with the rope. It is also effective to use a pulley in order to reduce the transmission loss of the caregiver's power.

Near the other end of the rope-like member, a power point member is attached to which a caregiver applies a force for helping the cared person to stand or sit.
The ingenuity of the power point was solved by creating “Abumi” to convey the “force to step on the foot” that can easily use the weight of the caregiver with natural gravity. The core is preferably the same rope as the rope member, but if it remains in the rope shape, it will hang down and the shape will not be fixed, so it may be difficult to put a foot on it. Therefore, an opening of about 10 to 15 cm can always be maintained through the resin tube. In the prototype, a general water hose cut to an appropriate length was used. However, there was adequate friction, strength was sufficient, and the material was inexpensive. Yes. (Fig. 4)
The gap between the stirrups and the number of steps may be adjusted appropriately according to the physique of the caregiver, but the distance is about 20 to 30 cm, and the number of steps is 85/20 ≒ 4 considering the difference between height and sitting height assumed in paragraph 12. In other words, it is sufficient to have about 5 steps, and good results are obtained even in actual trial production.
The stirrup-shaped force point member is important as a means for realizing the problem A that external power is not used.

In the present invention, a device for assisting the force applied to the power point is further added. This is because only the stirrups described in the previous paragraph may cause a “power gap time for stepping, discontinuous force”, and the power to support the cared person may be interrupted. Since this problem depends on the height of stirrups and the ability of the caregiver's lower limbs, this is not always the case.
In order to solve the problem of “blank time of force when stepping, discontinuous force”, a round bar (hereinafter referred to as a friction handgrip) is located near the lip of the bathtub separating the caregiver on the bathtub side / the caregiver on the washroom side. (Also referred to as a member). The most ideal position is ideally vertically long on the line connecting the stirrer and stirrer near the center of the bathroom. As a result, the rope and the frictional grip member can be brought close to each other. The caregiver can generate an appropriate frictional force by grasping the rope and the frictional grip member together (or pressing the frictional gripping member from above the rope). The frictional force is unexpectedly strong and sufficient to support the weight of the cared person.
Ideally, the attachment height of the friction grip member covers the range from the caregiver's waist to the face, so that the caregiver can easily control the friction braking force. On average, it is convenient that the lowest part of the friction grip member is 60 to 80 cm from the floor and the highest part is about 120 to 150 cm from the floor. Even when the mounting direction can only be horizontal for some reason, the mounting height should be in the numerical range in the vertical direction (60 to 150 cm from the floor). In the case of a bathroom, the material may be stainless steel, a solid resin, or a resin coated with other metals as the core, but wood is also practical enough when applied to other rooms.
The practical attachment position of the friction grip member is considered to be a vertical position near the edge of the bathing entrance and exit side of the bathtub. good. When the attachment position of the friction gripping member and the attachment position of the second fixing member are relatively adjusted so that the deviation is about 25 cm, the rope-like member passing through the second fixing member is along the immediate vicinity of the friction gripping member. The power point member hangs down below the desired position. The caregiver manually operates the rope-shaped member and the frictional gripping hand member, operates the power point member with his / her foot, handles them in combination, slowly seats the caregiver in the bathtub, or temporarily stops in the middle Or you can arrange a very convenient arrangement to stand up. By simply combining the friction of the hand, rope, and grip hand components as appropriate (the combination depends on the skillful part of the caregiver), the cared person can be raised and seated. In addition, since the expression of weight and friction is sufficient by the action of one leg and / or one hand, the remaining one leg and one hand (both hands in many cases in actual results) can be used freely during nursing care such as bathing. Therefore, while supporting the weight of the cared person, it is possible to attach a hand so that the upper body of the cared person does not become unstable by shaking in the horizontal direction.
When it is desired to perform a temporary stop during the operation for a long time, there is a utilization method in which the rope-like member is temporarily fixed by tying or hooking the rope-like member to the hand grip member.
Thus, it is possible to provide an auxiliary care device that is lightweight, has a small installation area, and is inexpensive without requiring external power such as an electric motor or a pressure cylinder, mechanical parts such as a gear or a ratchet mechanism, and realizes the problem A. A set of practical means is available.

It is possible to attach such care tools in the bathroom by post-processing or retrofitting without significant reinforcement work as described in the previous section, but prepare in advance so that future installation work will be almost unnecessary. In this case, an auxiliary support post or the like is unnecessary, and the appearance may be refreshed, and sufficient strength can be ensured.
In the present invention, it is a bathroom that makes it easy to attach an auxiliary care tool that assists a cared person whose physical ability including the lower limb has declined and a carer who helps the cared person to stand up and sit down,
1. Comprising at least two mutually spaced anchor members for attaching a securing member that supports and / or relays the caregiver's power to help the caregiver stand and sit;
2. The position of the at least two mutually spaced anchor members is
When the bathtub is viewed from above in a plan view and is substantially rectangular in shape, it is above both ends of at least one short side of the two short sides of the rectangle.
Provide a bathroom designed and manufactured as follows.
The two anchor members separated from each other need only be strong enough to support the weight of a person and do not support machinery, so there is no need for special design or manufacturing reinforcement. The impact on installation costs is very small and reasonable.

According to the present invention, the caregiver can exert the power for helping the standing and sitting of the care recipient with one hand or one foot, so that the surplus limbs support the caregiver's body in the horizontal direction, etc. You can use it freely. Since the caregiver's posture can be left standing, the caregiver's posture becomes very easy. This is particularly effective in reducing the burden on the caregiver in places where the caregiver's sitting posture is low, such as in the bathroom. Moreover, it does not require external power such as a motor, or mechanical parts such as a ratchet, and is light and safe and has a small installation area, so that it can be easily retrofitted in many cases. In addition, by preparing such a care tool when designing and producing a bathroom, preparations for attaching the care tool can be made easily and inexpensively.

The features of the present invention will be described below with reference to examples.
Example 1 is a nursing tool designed in a case where two elderly couples live while helping each other. The weight of the cared husband was about 60 kg, and the weight of the cared husband was about 40 kg. The lower leg of the husband was weakened, making standing movement difficult. The bathroom is a unit bath made of FRP, and the bathroom floor surface dimensions are about 1500mm each in the vertical and horizontal directions of the floor as shown in Fig. 5 and Fig. 6 (unit mm in the figure, parts that are difficult to see because of overlapping parts) The height is about 2190mm.
Caregiver who is easy to hold on the wall and handrails (only some of the handrails are shown in the figure) including movement and bathing from the dressing room (not shown), but with weak leg strength and arm strength Even if she grabbed the handrail, she could not stand up on her own, and her husband and helper were taking bath care. In addition, the bathroom and the dressing room and the passage leading to it are bent, so it is not possible to secure a space for installing a crane-like support mechanism, and it is not a house that was supposed to be installed like a crane before that. The building strength of the building is insufficient in the first place.

Since there is a clearance of 100mm or more between the wall surface of the unit bath and the wall of the house body, there is room for processing work, so the fixing member is attached to the anchor hardware, and the anchor hardware is attached to the FRP wall of the bathroom with toggle bolt and epoxy resin elastic Fix using an adhesive (EP001N manufactured by Cemedine). You can't use reinforced wood because you don't have access to the back of the unit bath wall, but it is better to reinforce from the back if possible.
You can drill a hole in the bathroom wall about 50 to 100mm below the ceiling, and fix the two anchor hardware using four toggle bolts and adhesive (details of the bolts are not shown). The front, rear, left and right positions are near the corner on the bathtub head side, and the two anchor hardware are separated from each other by about 800 mm. If it is in this position, even if a hardware etc. comes off and falls, it will not hit directly because it is outside the shoulder width of the cared person.

Attach an annular relay rope (about 100 mm in diameter) to the anchor hardware at the back of the bathroom, and attach a key ring with a gate of about 50 mm in length (aluminum metal fitting that opens and closes part of the ring with a spring type). There is no static load indication on the key ring. The relay rope and key ring serve as the first fixing member (5e) (see FIG. 7).
On the other hand, a pulley is attached to the anchor hardware on the left side of FIG. 6 via a relay rope as a second fixing member (5f). The car part of the pulley is made of resin of unknown material, and the other parts are made of stainless steel (because of its weak texture and magnet attachment). Use a static load display of 65 kg (to be exact, it means 65 kgf).

The rope-like member (5r) is slippery and is made of nylon braided rope with a diameter of 5mm so that it will be soft and not feel painful. The nominal static load is over 700kgf. One end of the rope-like member (5r) is connected to a key ring with a gate which is a part of the first fixing member (5e), and the middle portion is passed through the pulley of the second fixing member (5f).
A stainless steel C-shaped ring having a diameter of about 5 mm as a suspension member (5s) is hooked on the rope-like member (5r) near the middle between the first fixing member (5e) and the second fixing member (5f). hang.

Two support members (5h) made by sewing towels in an annular shape (FIGS. 3a and 3b) are prepared and bundled together with an annular rope such as a nylon rope to produce an annular harness (FIG. 3). 3a, 3b). Nylon ropes are bundled together by one piece, so that it is convenient that the operation of hanging on the suspension member (5s) can be performed only once. In addition, it is more convenient to bundle two bulky towel cloths together and pass them through the suspension member (5s) in terms of size.

As shown in the photograph in FIG. 4, the force point member (5p in FIG. 6) is “buffy” or “ladder-like” at intervals of about 20-30 cm while passing the rope-like member (5r) through the flexible vinyl tube. It has a structure with several stages. The vinyl tube may be temporarily fixed to the rope-shaped member with an adhesive or a sewing thread so that the vinyl tube does not slip in the length direction.

A grip hand member attaches a commercially available handrail (5g) for bathrooms to the head side of the bathtub and near the upper edge of the bathtub (see FIG. 6). The mounting position was designed to avoid the FRP panel seam (not shown) and away from the 20-30 mm bathtub from directly below the second fixing member (5f).
In this example, the anchor and the gripping member explained at the beginning are considered as retrofitting. However, it is easier to attach the reinforcing material in advance when installing the bathroom (when building the building). It is more desirable because it can be easily and reliably installed at the factory.

FIGS. 8 and 9 are schematic views showing the use of the auxiliary care device of this embodiment (the members and the like common to FIGS. 5 and 6 are omitted from the symbols and names).
Prior to entering the bathtub, a circular harness is attached to both the thighs of the cared person (5a) in such a way as to wear clothing. The rope bundled with the annular harness may be hung on the suspension member either before or after the cared person enters the bathtub, and in an order that the carer can easily operate.
The caregiver (5b) grasps the rope so as to press it against the handrail, and at the same time steps on the stirrup-shaped force point member with his / her foot, so that the weight of the cared person can be supported twice. It is sufficient to hold and hold the rope with one hand (in Fig. 9, placement and left hand), and to step on the stirrup, one leg (in Fig. 9, placement and left foot) is sufficient, and the remaining free one hand / one foot (right hand) • The right foot can be used freely to help the caregiver step on or when the caregiver's posture is unstable. Furthermore, when the care recipient's posture is stable, the power is sufficient by simply stepping on the stirrup-shaped force point member with his / her foot, so that both hands and one foot are free and care can be performed very easily.
When the cared person sits from a standing position, the stirrer is usually unnecessary. The caregiver only needs to loosen the force pressing the rope against the handrail and slide the rope, and the frictional braking force adjustment is easy.
When the cared person stands up from the sitting position, the carer may step on the stirrup or pull the stirrup (which is at a higher position at that time) by hand. The principle of a moving pulley generates nearly twice as much force, and the caregiver's posture that produces the force can be left in a natural position, greatly reducing the burden on the caregiver.
Before the implementation of this example, bathing every 1-2 days with two people, a wife and a helper, is perfect, but after the implementation of this example, only one wife can take a daily bath, It can be expected to help improve the hygiene and blood circulation of care recipients.

The parts required in the present embodiment are summarized as follows.
・ Anchor: 2 ・ Auxiliary support: 0 ・ Fixing member: 2 (relay rope and key ring, relay rope and pulley)
・ Rope: 1 piece (5mm diameter nylon braided rope)
-Hanging member: 1 piece (stainless steel C-shaped ring)
Support member: 1 (annular harness)
・ Strength member: 1 (A stirrup is produced on the rope extension)
・ Hand grip materials: 1 (commercial handrail for bathroom)
In the present embodiment, the first and second fixing members are not limited to being fixed to the same wall surface, but may be fixed to other portions or may be fixed by providing a plurality of anchors on two or more surfaces. When there is no suitable structure for attaching the fixing member on the same wall surface, the wall surface or the ceiling surface may be adjacent to each other, or may be fixed to an auxiliary support post retrofitted indoors.
In an actual indoor structure, especially a bathroom such as a unit bath, there is a case where an appropriate structure and strength for attaching a fixing member cannot be obtained, or there is a case where it is not desired to make a hole for anchor attachment on the wall. Can be used.

The backup plan considered in the same case as the first embodiment is the second embodiment. This is an alternative in order to reduce the number of holes in the bathroom wall and when such hole machining is difficult due to the material room on the bathroom wall. In this embodiment, one auxiliary support column is used.

The auxiliary struts (10w) were installed diagonally and diagonally along the wall surface so as to be stable in the left-right direction of FIG. Use a counterplate to prevent the force from concentrating on one narrow point on the part that hits the wall of the bathroom, to prevent slipping, and to prevent the auxiliary strut timber from being corroded by water. A cork plate is used for the upper left corner of FIG. 10, and a shock-absorbing rubber plate is used for the lower right. A through hole is made in the vicinity of the upper end of the auxiliary support column, tied there through a relay rope, and a key ring with a gate of about 50 mm in length is applied as in the first embodiment. In this case, the auxiliary strut with a through hole serves as an anchor member. A part of the weight of the cared person is applied to the auxiliary column in the length direction, and the remaining weight is supported by friction with the wall surface. In addition, the external force that folds the auxiliary column does not work, so the timber should be light and thin. Here, cedar wood having a length of about 1920 mm and a thickness of about 30 mm is used. Since the passage leading to the bathroom is narrow, two short timbers are added using an angle-shaped hardware 10j immediately before the bathroom to form an auxiliary column having a total length of 1920 mm.
If the position where the auxiliary column is provided is along the side wall of the bathtub, the daily bathing is not an obstacle. When applying to nursing care that helps to get up in bedrooms other than bathrooms, a fixing method such as a two-point set in which a rope for fixing is wound around a structure such as a duck or a rail, and rope members are connected via ring-shaped hardware Should be devised. In addition, when applied to a toilet, the fixing member can be attached by appropriately combining a durable indoor structure such as a duck and an auxiliary column.
The anchor at the upper left of FIG. 11 is used as an anchor after retrofitting a commercially available shower curtain fixture. Moreover, since there is a possibility that the auxiliary support column may fall to the left as seen in FIG. 11, the structure is such that it is supported on the shower curtain mounting tool by a commercially available stick. There will be about 150 g of a stick on the cared person's head, but it is light and has no corners and a rubber cap at the end, so even if the stick stick falls, there is no safety problem It seems not.

FIG. 11 also shows a state in which the support member is supported so as to come into contact with the body at the heel portion of the care recipient.
As a way of supporting the cared person by the support member, in other comparative studies, the body of the cared person is made throughout the ribs so that the towel is sewed into a slightly longer ring than in the case of Example 1 Prototype evaluation that supports The feeling of tightness that seems to tighten the chest seems to be unexpectedly strong, and the trial was interrupted because it was cramped and painful for the care recipient.

Other points of the present embodiment are substantially the same as those of the first embodiment, but the movable portion of the pulley used for the second fixing member (10f) is not only the axle (in the direction perpendicular to the force of the load, the X axis), The neck part (so-called Z axis parallel to the force of the load) that suspends the pulley is selected so that it can rotate, and even if the direction of the rope changes, the pulley swings the neck and follows the direction of the rope. A static load display of 65 kg is easy to obtain. However, even if the neck portion that suspends the pulley does not rotate as in the first embodiment, the relay rope absorbs the torsion, so there should be almost no stress on the entire tool. In addition to the pulley, it is also effective to use a carabiner for the second fixing member. In this case, there is a demerit that the friction becomes slightly larger and the caregiver's power loss increases, but conversely, if this friction is used, the stirrup that supports the weight of the cared person and the friction of the rope on the gripping member The benefit is that the braking burden is reduced.

A carabiner with a thickness of about 10 mm and a length of about 100 mm is used as the suspension member. A pear-shaped aluminum alloy carabiner is suitable, and it has a shape and finish that is tailored to the human hand (the chamfer is polite and has almost no corners), so that the radius of curvature of the part where the rope is applied is increased. There is an advantage that the device is devised and the friction with the rope is sufficiently small, and there is little damage to the rope. In order to further reduce the friction with the rope, a pulley can be used as the suspension member. However, when compared with the prototype device, there was no difference that felt special lightness.

The usage of the auxiliary care tool of the present embodiment is the same as that of the first embodiment. In this case, after making a comparative explanation of Examples 1 and 2, it was confirmed that Example 2 which does not need to be drilled on the wall surface can be temporarily attached and care can be easily provided by the power of a light weight wife. did it.
The necessary parts in this embodiment are summarized as the following 12 points.
・ Anchor: 1 ・ Auxiliary support: 1 (length: about 1920mm)
・ Supplementary material: 3 (buffer cork board, rubber board, pulling stick)
・ Fixing members: 2 (relay rope and key ring, relay rope and pulley)
・ Rope: 1 piece (5mm diameter nylon braided rope)
-Hanging member: 1 piece (aluminum alloy carabiner)
Support member: 1 (annular harness)
・ Strength member: 1 (A stirrup is produced on the rope extension)
・ Hand grip materials: 1 (commercial handrail for bathroom)
In the first and second embodiments, when the arrangement of the bathtub (usually the head and upper body is placed) is opposite, or the caregiver's dominant arm is reversed, the whole may be reversed symmetrically.

In this example, a comparative study of the material of the rope-like member used and the method of knitting was performed.
As materials, nylon, polypropylene, vinylon, polyester, polyethylene, or some of these mixed materials were compared. The method of knitting was "three-strike", and the materials were compared. However, nylon and polypropylene were flexible, slippery and drained well. The vinylon has a problem that the friction between the ropes is somewhat large, it is difficult to loosen it when tangled, and because it has good water retention, it does not drain well after being used in the bathroom. Polyester was not used this time, as the friction between the ropes is somewhat greater and nylon is not as smooth as nylon, so it is not routinely knotted or loosened. In addition, in this comparative study, there was a problem that the range of selection was limited because there were few samples available. Polyethylene is very hard and feels slightly painful to the hand, and therefore, friction with the handrail is small and difficult to control, which does not meet the object of the present invention. From these comparisons, two types of materials, nylon and polypropylene, were selected.
The comparison of how to knit the rope was made by comparing the easily knitted rope with the three-punch, but it was excellent in softness, difficulty of entanglement, and ease of control of friction when gripped on a handrail. It turns out that a knitted rope is suitable. In addition, it seems that there are several names for the way of knitting, and the knitting rope seems to be called hammering.
Nylon braided ropes are available in various sizes on the market, so we also compared the thickness of 4 to 8 mm in diameter. The 4mm diameter is a little too thin and may feel a little pain when operating. If it is 5mm or 6mm, there is no problem with moderate operability. 8mm is acceptable, but there is no special merit such as excessive strength in terms of load resistance due to excessive strength and longer time for drying after getting wet.
Finally, a comparative study of nylon braided belts (width 10, 20, 30mm) was made, but the strips are as soft and difficult to tangle as nylon braided ropes, and when gripped on a handrail The band width of 20-30mm was good to moderately control the friction. However, in the case where a pulley is used as the second fixing member (7f), the size (the width of the vehicle) is adjusted to the belt, so that there is a demerit that the size of the pulley and thus the price becomes very high. On the contrary, when making stirrups, there is an advantage that it is easy to make a strong knot.
Based on the above results, it was decided to use nylon or polypropylene knitted rope with a diameter of 5 to 6 mm as the rope-shaped member.

Example 4 is an example designed in a case where two elderly couples live together while living together with their children. The husband who is the care recipient has a weight of about 70 kg, and the husband who is the caregiver has a weight of about 45 kg (details are not confirmed). It becomes difficult and the family is helping to stand up with two people. The bathroom is tiled. 12 and 13 show a part of the bathroom, and the floor surface dimension is about 2 m in length and width.
There is room in the bathroom and the approach so far, but the finish is tiled, so to install a mechanism like a crane-like support mechanism or robot arm, remove the concrete and mortar once and start the foundation work again This is a case that is necessary because it is necessary and it is troublesome including the cost.

In this embodiment, the indoor clothes-drying rail (12i) and the handrail (indicated as 12g gripping member in FIG. 12) are already attached to the bathroom. Of these, the indoor clothes-drying rail (12i) is sturdy, but its position is almost in the middle when viewed from the short side of the rectangular bathtub (12t), and is about 30cm away from the bathtub edge. It is difficult to use. The reason is that there will be a pulley and other parts above the head when taking a bath, and there will be safety concerns, and as shown in FIG. 13, the body of the cared person is far from the back of the bathroom, that is, the carer. It will be more stable.
Therefore, this case was designed to use two auxiliary struts, 12w auxiliary strut-1 and auxiliary strut-2. Auxiliary support column-1 stands diagonally along the wall at the back of the bathtub and is inserted inside railing-1 so that auxiliary support column-1 does not slide to the left as viewed in FIG. Further, when viewed from the short side direction in FIG. 13, the support rod is designed to be supported by passing it between the indoor clothes drying rail (12i) so that the upper side of the auxiliary support column-1 does not fall to the right in the drawing.
Auxiliary support column-2 stands up straight from the floor using thin plate-like wood, and is fixed using a gripping member (12 g).
The first fixing member and the second fixing member are attached to the auxiliary strut-1 and the auxiliary strut-2 (12w) in the same manner as in the first and second embodiments. A pulley is used as the second fixing member (12f), but it can be changed according to the caregiver's wishes.

The rope-like member (12r) is substantially the same as in Examples 1 and 2, and a polypropylene braided rope having a diameter of 6 mm is used. One end of the rope-shaped member (12r) is connected to the key ring which is the first fixing member (12e), and the other end portion to the middle portion is passed through the pulley of the second fixing member (12f), and the first fixing member (12e) and A pear-shaped aluminum alloy carabiner is used as the hanging member (12s) for the rope-like member (12r) near the middle of the second fixing member (12f).

As the support member (not shown), an annular harness made of a cloth that is easy to wash and dry, such as a towel or nylon band or a webbing material, is used. There is no change in the basic structure that supports the weight of the cared person's thigh.
In addition, it seems that it is possible to support care by lifting the whole body by replacing the lower limbs of the care recipient with a single hammock-like member that is supported by the elbows instead of the hip joints.

The force point member is integrally formed on the rope-like member extension line in the first and second embodiments, but is divided from the rope-like member in this embodiment. The point where the rope-like member (12r) and the force point member (12p) are connected is in the vicinity of 12j in FIG. The connection is made with a key ring as in the case of attaching a fixing member. By dividing the body into two bodies, it becomes easier to carry out subsequent maintenance such as removing or disassembling auxiliary care equipment during inspection of stirrups or pulleys, or replacing it with another shape. In addition, if the caregiver inadvertently slides the rope if the position of the connecting point is adjusted appropriately, the key ring will be caught in the narrow path through which the rope passes through the second fixing member (pulley), and the cared person will violently hold the hips. It also serves to prevent such failures. In this embodiment, two types of stirrups were prepared: a triangular shape as in Example 1 and a semicircular or annular shape. After assembling the auxiliary care equipment as a whole, compare which shape stirrer is easier to use. There is a possibility that the ring shape is easier to set up than the triangular shape studied up to Example 2, and the selection is made based on the result of trial use.

In addition, in the prototypes of Examples 1 and 2, the power point members 5p and 10p rarely approached the wall, making it difficult to apply the foot. In this example, as shown in FIG. 14, a cup-shaped member (12 cup) (in terms of shape, it may be more appropriate to say a dome shape) was prepared. It is planned to compare whether the cup-shaped member is effective as a device for attaching the cup-shaped member below the gripping member 12g so that the power point member (12p) is not too close to the wall.

  In addition, what is compared in the present embodiment is the strengthening of the power for helping to stand. In this case, the cared person's physique is large and the weight difference with the family is large, so it may be necessary to operate the stirrup and rope by two people, especially when helping to stand up. Therefore, the members are arranged so that the comparison can be performed by two caregiver operations as shown in FIG. Use this to confirm the effects and issues of 2-person care.

The necessary parts in this embodiment are summarized as follows.
・ Anchor: 0 ・ Auxiliary prop: 2 (Auxiliary prop-1 length approx. 2380mm, Auxiliary prop-2 length approx. 2130mm)
・ Supplementary materials: 4 (buffer cork board, rubber board, pulling stick)
・ Fixing members: 2 (relay rope and key ring, relay rope and pulley)
・ Rope: 1 (6mm diameter polypropylene knitted rope)
-Hanging member: 1 piece (aluminum alloy carabiner)
Support member: 1 (annular harness)
・ Power point member: 1 (including stirrups separated from the rope body and connecting key ring)
・ Grip components: 1 (uses existing handrails in the bathroom)
・ Cup-shaped member: 1
The manner of using the care tool of this embodiment is the same as that described in the first and second embodiments.

In Example 2, in order to divide the long auxiliary strut (10w) for easy transportation and assembly, the two auxiliary strut timbers are divided into two parts using angle hardware (10j) and through screws (bolts and nuts, 16s). did. FIG. 16 shows a schematic diagram of the divided / joined structure.
In addition, as shown in FIG. 17, a folding structure using a hinge (17h) and a buckle-like hardware (general name unknown, 17b) is also easy to transport, assemble and disassemble. The combined use of the split type and the folding type is also appropriately performed according to the rationality of design, processing, and construction.
As a result of the division or folding structure, the length of one auxiliary strut material is shortened. If the two material combinations are applied to the second and fourth embodiments, the auxiliary strut having a total length of about 1900 to 2400 mm can be shortened to about 950 to 1200 mm, so that it becomes a practical length that can be transported by courier or passenger car. . In addition to being easy to handle indoors at the installation site, if you want to insert it inside the handrail-1 described in Example 4, remove the handrail-1 and remove the auxiliary strut-1 (12w1) of about 2380 mm. When it was necessary to reattach the railing-1 after the installation, there is an advantage that the number of work steps can be reduced because it is not necessary to remove the railing-1. When two or more auxiliary struts 2 (12w2) described in the fourth embodiment are combined, the effect on the work man-hour is small because the installation is originally easy. However, the advantage of ease of transportation and handling can be obtained as in the case of the auxiliary column-1.

In Examples 2 and 4, long auxiliary struts (10w, 12w, etc.) were cut in accordance with the dimensions of the bathroom each time. However, it takes time to finish chamfering, rounding, and painting at the installation site. In order to rationalize this point, the length of the auxiliary column should be standardized to a typical length, an extension mechanism should be incorporated, and adjusted at the installation work site.
This makes it easy to keep the work level for each individual construction above a certain level and makes it possible to standardize the length of the auxiliary struts, leading to a reduction in member costs.
FIG. 18 is a schematic diagram illustrating an example of a mechanism for adjusting the length expansion / contraction. This prototype is not a whole auxiliary care device but an element prototype only for the auxiliary support column. The end of the auxiliary strut (equivalent to 10w, 12w, etc.) is cut to about 100 to 200 mm, for example, and an insert screw (18i) is embedded in one of the materials. The other material may be fixed by screwing an adjusting screw and filling with an adhesive or the like. The insert screw used was Onimut nut E type, M8 * 25mm (available from limited companies such as Nakamura Shokai), but can be selected as appropriate. The adjusting screw (18a) used was 100 mm, but it may be selected as appropriate. As a result, an expansion / contraction mechanism that has a strength sufficient to withstand the load of compressive force applied in the direction of the length of the auxiliary column (in the case of the present invention, the weight of a person) has been completed.
Although the insert screw is embedded only in one material in FIG. 18, it may be embedded in both as required. In FIG. 18, the shorter end cut to about 100 to 200 mm is cut off into a trapezoid and used on the upper side of FIGS. 10 and 12, that is, the side to which the fixing member is attached. In the lower part of the lower side of FIG. 10 and FIG. 12, water may be splashed in the bathroom, so that the insert screw and adjusting screw are prevented from getting wet.
The screw structure for adjusting the length expansion / contraction may also serve as a joining structure for the divided auxiliary struts.

A comparison between the auxiliary struts used in Example 2 and Example 4 and the auxiliary struts incorporating the division, folding, and expansion / contraction mechanisms as described in the previous paragraph is shown in FIG. Element trial 1 is the result of the element trial of only the auxiliary column part, and the same element design 1 to 3 was performed by desk calculation.
In Element Prototype 1, the auxiliary strut is divided into 870mm2 material, and it is composed of a total of 3 materials including the material with the adjustment screw embedded.
In Element Design 1, the auxiliary strut was divided into 950 and 790 mm2 materials. The shorter auxiliary strut material is 950 mm (= 790 + 160), combined with the 160 mm length of the material that is fixed with the adjustment screw, and is the same length as the longer auxiliary strut material. It is more convenient to have the same length when storing ready-made materials, packing and shipping.
In Element Design 2, the auxiliary support post is divided into 3 pieces of 750 mm so that the length is 2350 mm after assembly, and it is composed of a total of 4 pieces with materials embedded with adjusting screws.
In Element Design 3, the auxiliary struts were divided into 1200mm2 materials so that the length was 2400mm after assembly, but the extension mechanism for adjusting the length was not incorporated. Although length adjustment (cutting) needs to be performed on site, it has the advantage of being easy to transport and is reasonably reasonable.

The care device of the present invention is characterized by a small number of parts and light weight, but it can be assembled and disassembled in a short time at the site of use by adding further ingenuity and applied to visiting care It becomes possible to do.
20 and 21 are diagrams showing examples of such application designs based on the fourth embodiment, and a side view and a front view, respectively. The basic structure of the auxiliary strut is the same as that of the fourth embodiment. However, the split / joint structure (20j1) (20j2) and the expansion / contraction mechanism (20a1) (20a2) are adopted so that it can be assembled and disassembled at each use site. did.
Further, in the fixing method of the auxiliary strut-2, it is not a fixing method using the grip member (12g) as in the fourth embodiment, but a method in which two additional tension bars are further added and temporarily fixed. In order to prevent the auxiliary support column-2 from falling down in the bathtub longitudinal direction, a tension bar -A (20c1, upper double line in FIG. 20) is used at a high position parallel to the clothes drying rail (12i). Further, in order to prevent the auxiliary struts 1 and 2 from falling in the left-right direction of the front view, the tension rods -B and C (20c2, 20c3, upper double line in FIG. 21) are used. The short stick used in Example 4 is not necessary in this case. The split / joint structure may be folded as required.
If an existing clothes drying rail or shower curtain rail is in a position convenient for attaching the fixing member, it may be temporarily fixed thereto by a clamp mechanism or the like. In that case, such a clamping mechanism may be provided in advance in the auxiliary support column.
In this way, the care tool of the present invention can be assembled and disassembled every time it is used, and can be easily used for visiting care. The time required for assembly and disassembly is estimated to be 15 to 30 minutes, and the assembly can be completed while filling the bathtub.

Another idea is to standardize the length of the auxiliary strut and make it from aluminum. For example, by combining a split / join or foldable type as shown in Fig. 19 with an expansion / contraction mechanism, three standard length auxiliary struts of 2000 +/- 75mm, 2150 +/- 75mm, and 2300 +/- 75mm are available. Can be made of aluminum.
FIG. 22 shows a schematic diagram of the structure (a part of the vicinity of the spring is a sectional view). The auxiliary strut material is shortened by using a split type using a joint hardware as in Example 5 or a folding type combining a hinge and a buckle-shaped hardware (22j). A rotatable angle adjustment mechanism (22a) is provided at both ends of the auxiliary support column to facilitate the angle adjustment work when leaning against the wall surface. Attach anti-slip and cushioning rubber to the bottom. The expansion / contraction mechanism can also utilize a method of combining the length adjusting hole (22h) and the button (22b), which is often seen with a walking aid cane.
Such a device makes it possible to rationalize the production of the auxiliary struts, greatly reduce the number of assembly steps at the installation site, and makes the assembly and disassembly work much easier for use in visiting care. Combined with standardization of auxiliary strut length, the cost can be reduced.

In the above embodiment, the anchor for attaching the fixing member to the existing bathroom by post-processing or adding an auxiliary support column is provided, but the anchor member as shown in the first embodiment is located at the high position and corner of the bathroom. It is difficult to work because it is necessary to install it, and it is difficult to attach the backing reinforcement plate. Therefore, it is desirable to attach an anchor member at the time of initial construction of the bathroom.
In the case of an anchor member having a simple structure as shown in the first embodiment, even if there is no cost even if an option is ordered at the time of initial construction of the bathroom, even those who are not worried about the current physical function are prepared for the future. Can be attached.
The specific shape and structure of the two anchors, in addition to the anchor hardware as in the first embodiment, the shower curtain mounting device as in the second embodiment, as long as it is strong enough to support the human weight, and the fourth embodiment It may be a rail for indoor clothes drying. Parts such as shower curtain fittings and indoor clothes drying rails are often installed in conventional bathrooms and are well known, but the conventional installation position is only near the upper side of the bathtub (washing area). In order to realize the present invention, it is necessary to attach to the upper part of the bathtub back side (back wall side). As shown in FIG. 6 and the like, as the left and right positions, the vicinity of the upper part of both ends of the short side of the rectangular bathtub is appropriate.
A rod-like frictional gripping hand member (handrail or the like) may be retrofitted when necessary. This is because the frictional grip hand member is not a part where a large force is applied intensively, so the necessity of backing reinforcement is low, and the installation position is within the range of the person's height, so that the retrofitting work is easy. Of course, it does not matter if it is installed at the same time as the anchor member in the initial construction of the bathroom. The protruding from the wall is a round bar of several tens of millimeters, so it does not interfere with normal bathing.

  By optimizing the arrangement and structure of auxiliary care tools attached to the room, the caregiver's ability to support standing, getting up and sitting can be supported by the power of one caregiver. The caregiver is freed from heavy work that supports the cared person in a leaning forward position. No mechanical parts such as external power are used, and there are no heavy parts above the head, so safety is excellent. Easy to install and can be installed in older households and old houses. It can be widely applied to places such as bathrooms, toilets, bedrooms, etc. that care for people whose lower limb motor skills have declined.
