JP2015226855A - Bathroom in which auxiliary nursing care instrument for assisting care receiver and care giver can be easily installed - Google Patents

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

  The present invention relates to an auxiliary care device for assisting a carer with impaired exercise ability, particularly in the exercise ability of lower limbs, and a carer who assists in standing up and sitting, and a bathroom for facilitating attachment of the care device. is there.

Movement ability, in particular the movement movement of the lower extremity who suffers from weakness as a typical exercise movement, standing up from sitting position and raising body from supine / recumbent position, and vice versa There is a seating motion.
When a carer who assists these movements performs a support operation, the carer is often in an unstable posture with a bow, and it is difficult to apply sufficient force. In addition, when the carer is an elderly spouse etc., it may be very difficult for the carer to take the above unstable posture or to exert sufficient power in the unstable posture, It is often impossible in practice, and it is also a situation where it may impair the health of the carer's legs and waist because of the unreasonable posture.
Most typically, there is an exercise capacity, and in particular, movement of standing up after sitting in a sitting position by a person who is able to walk for several steps, because the exercise capacity of the lower limbs is deteriorated. In many bathrooms, the bottom of the bathtub is at the same height as or lower than the floor of the bathroom, so the caretaker can not stand in front of the support operation by the caregiver when the cared person can not stand up by himself Becomes more difficult. If you step into the tub, your carer's posture should be somewhat steady and easier to apply, but usually it does not take that drastic action. In a bathroom where the floor is wet and slippery, the carer's feet become more unstable and the support operation becomes more difficult.

The following are disclosed as tools and equipment to support the movement accompanying walking and bathing of the person whose physical movement ability has deteriorated, and as a nursing care and technology to support the support operation of the carer. .

  For example, although a lift chair driven by a motor is disclosed in Patent Document 1 and JP-A-2009-006093, a motorized mechanism is incorporated in a bathroom with a lot of moisture, and in a home where elderly people help each other There is a problem in the safety at the time of misoperation. Moreover, in order to fix the support column which has sufficient strength so that it may be clear from FIG. 5 etc. of patent document 1, reinforcement of foundation works, such as a bathroom, is essential, and considering the installation area estimated from drawing together. Post-attachment to a standard bathroom, such as a unit bath made of aluminum, was difficult.

In paragraphs 79 to 83 and FIG. 14 of Patent Document 2 and JP-A-2006-288569, single-acting cords fixed to opposing wall surfaces parallel to the longitudinal direction of a bathtub in a bathroom (Patent Document 2 and 71 of FIG. 14) Rodless cylinder (60 in FIG. 14 of Patent Document 2) serves as a power source for moving the cared person in the vertical direction via a moving pulley, and is fixed near the ceiling so as to be supported by the opposing wall surface. A nursing care apparatus is disclosed, in which a magnet type rodless cylinder (20 in FIG. 14 and FIG. 14) serves as a power source for moving a cared person in the horizontal direction. The magnet type rodless cylinder is an entire carrier (82 of FIG. 14) which is integrated with two movable constant pulleys for changing the direction of the cord (55 of FIG. 14 of 55). Because it moves in the direction, it also enables assistance to move the care recipient left and right.
Problem A: A power motor is unnecessary, but a special external power member such as a hydraulic cylinder is required.
In FIG. 14, the left end of the cord is fixed to the end of a magnet type rodless cylinder and stretched substantially horizontally, and the direction is changed substantially vertically downward by a fixed pulley integrated with a carrier 2. The chair lift-like member in FIG. 14 (without the symbol in the figure) is turned about 180 degrees by the moving pulley at the top, and is caught by another fixed pulley incorporated in the carrier. With the latter fixed pulley, change the direction approximately 90 degrees to the horizontal right again, and bend vertically downward with the fixed pulley (75 in FIG. 14 and FIG. 14) attached to the right end of the magnet type rodless cylinder It is connected to a single-acting linear rodless cylinder that is a power source for lifting and lowering. As shown in the figure, there are a total of 5 pulleys, and the number of parts that can be read from the drawing, such as cords, rodless cylinders, fixing brackets etc., is about 10 points (total 15 points, 2 rodless cylinders are 2 points as a module) And using). The weight of these mechanisms is estimated to be about 50 kg (including 15 liters of water to be filled in the cylinder) as estimated from the dimensions estimated from the figure, and in addition, considering the weight of the fixture and the care recipient It will be over 100 kg. Since it is difficult to support it only by the adhesion to the left and right wall surfaces or by the frictional force by the support (it is almost impossible with FRP unit bus), in paragraph 82 the rodless cylinder is supported by columns etc. to supplement the strength to the left wall surface. Although it suggests a device, it should be necessary to support the column in the longitudinal direction of the bathtub, the overall weight and the installation area are large, and the associated installation work becomes large. Construction seems to be possible, but there is still about 50 kg of machinery above the carer's and carer's head, which is undesirable for safety.
Problem B: The number of parts is large, the installation area is large, and the reinforcement work is large.
Problem C: A heavy mechanical device is overhead, which is not preferable for safety.
As a basic design for nursing care, when a person capable of “holding by himself or moving a few steps” premised in the present invention is used, a nursing care mechanism located approximately at the center of the bathtub shown in the figure It is difficult for the carer to support the caretaker's posture, which shakes in an unstable manner, and it is necessary to devise and improve it, as it can not lean on the back while sitting in the center of the bathtub. The size of the machinery and the installation work space are estimated to be 40 cm from the wall in the case of this document, but the care recipient wants to be a little closer in order to hand over the wall etc.
Problem D: A carer's body is located near the bathtub end by simplifying the structure, and devices and equipments need to be downsized for the purpose of well suppressing the shaking of the body and supporting the carer easily. .
Problem E: It is necessary to devise a hanger for the cared person who can hold it by himself.
In Patent Document 2, the role of the caregiver is to move the care receiver on the carrier from the washing place toward the bathtub by gently pushing it and moving it to the left and right (Patent Document 2, paragraph 70), It plays a role of operating the up, down, left, and right movement of the carrier using a remote control-like push button type switching valve (Patent Document 2, paragraph 83). There is still enough room for exercise and movement of the caregiver.

Patent Document 3, paragraph 31 of Japanese Patent Application Laid-Open No. 2002-000671, and FIG. 8 are devices that assist in getting up and walking that can be applied to the care recipient in the nursing need status section 2-3, and “slingers”. A harness-like loading sheet (A to C in FIG. 5) is disclosed. Also in the disclosure of this document, a rigid rail-like crane mechanism and a motor drive mechanism are required on the ceiling etc. (Issues A, B, C), and a device for suppressing body sway of the care recipient (Issue D). The rest will depend on the effort of the carer as it is. In addition, the harness-like loading sheet is suspended by 4 to 6 ropes so that the cared person can stand on his own without the help of the carer, and since it has a bowl-like shape, it is used for bathing as it is. It is expected to be difficult to use even if applied. In other words,
Problem E1: There are four to six ropes around the body that interfere with washing of the face, etc., and tend to be in a state of being pinched even if the rope is mixed,
Problem E2: The crotch area I want to clean and covered is covered with a bowl-shaped load sheet and difficult to wash,
And so on.

The walk supporting device which does not require power sources, such as a motor, is disclosed by patent document 4 and Unexamined-Japanese-Patent No. 2009-17922. Paragraph 23 of this document and FIGS. 1A and 1B show a load-free structure in which the cared person is statically suspended and stably held by a combination of a rope and a fixed pulley with a part of the cared person's weight. It is consistent with the basic premise of the present invention in that a part of the weight is supported by a rope and the rest is supported by the care recipient's own foot. However, it is the starting point of the technique of this document to support walking training after having fixed the cared person stably in the standing position on this support device, and the device for raising the posture from sitting position to that position is not disclosed The application to the standing up and sitting movement at the time of bathing and the problem and solution for it are not shown.
The walking support device includes four fixed pulleys (patent reference 4 and symbols 103a and 103b in FIGS. 1A and 1B), in which the cared person's body is moved left and right inside the frame (symbol 300). The pulleys are fixedly attached to the frame, as there is no need to do this. Do not use moving pulleys. Weight relief device main body consisting of elastic members such as ropes and springs provided independently of the cared person's body during walking training that would lose balance and tend to fall down (Patent Document 4, FIGS. 1A, 1B Support using symbol 210).
In other respects, the harness disclosed in Patent Document 4 extends from the hips of the cared person to the left and right of the body and to the front and back of the body up to both shoulders and around 4 to 6 around the body during bathing. The previous problem E1 resulting from the presence of the rope is not solved.
In addition, the harness can be separately applied to both the left and right hips, so the problem E2 of Patent Document 3 is solved, but a corset-like band for firmly holding the cared person's body completely covers the upper body, so it will be in the way Needs improvement.
In addition, the role of the carer in Patent Document 4 is to provide support (burden) to the extent that he / she puts his hand on the walking support device when the cared person is likely to fall, even without being always accompanied. , It can be understood that it does not use the power of care and support positively, and it is understood that there is sufficient remaining capacity (patent document 4, paragraphs 2 and 3, etc.).

Patent Document 5, Japanese Patent Application Laid-Open No. H08-000698 has an exercise capacity sufficient to stand up in a bathtub (paragraph 10) for attachment of a supplementary care tool for a bathroom (paragraph 10) for a care recipient 3 or more of the anchor members (14 brackets and the mounting bracket 6 shown in FIG. 1) to be attached, and 3 or more fixing members (the connecting members 5 shown in 14 paragraph and FIG. 1) corresponding to the anchor members. And
Disclosed are a bathroom and a care aid, in which the position of the grip 8 is shifted (paragraph 19) while adjusting the length of the connecting member (paragraph 19) and the position is to be freely changed as required (paragraph 23).
Patent Document 6, Japanese Patent Application Laid-Open No. 2000-254196 describes a configuration (FIG. 2) of attaching an anchor member to a ceiling surface for attachment of a soft bag-like bath (9th paragraph) for nursing which can be stored or transported. There is.
We also surveyed the bathroom in the range of existing products, but while devices and mechanisms have been proposed to attach something like a rail or robot arm around the bathtub when designing the bathroom, most of them are homes specializing in nursing care And in the case of facilities, etc., in the sense of preparing for the future care in the individual general household bathroom, there is only attachment of a handrail and an easy-to-use chair etc. in the sense. Although such basic devices and mechanisms are very important, other devices for assisting and assisting the movement of the care recipient when moving to a comfortable chair or bathtub while being held by the handrail are sufficiently provided. I found it was not.
In reality, it is impossible to predict and prepare for the nursing care issues that each household will face in the future at the design stage when purchasing a home, and it is unreasonable to speculate on specifications for unpredictable problems. It is impossible to design and construct a foundation structure for the ceiling rail and robot arm that can not be determined in advance, and in addition to the problem of cost, most preparations for future care equipment installation are carried out Not. However, if simple, reliable and inexpensive preparation can be selected, many homes should be able to prepare for the future in the future.

The problem to be solved by the present invention is to provide an auxiliary care tool for assisting a carer whose exercise ability, in particular the exercise ability of the lower limbs has deteriorated, and a carer who helps standing up and sitting down, and It provides a bathroom that can minimize or eliminate the additional work to attach such auxiliary care devices. Here, "a cared person whose exercise capacity of the lower limbs has deteriorated" means a person who can walk or stand for several steps. (The device of the present invention can not assist in the standing and sitting of the care recipient who can not maintain the standing position at all, which I would like to make possible by future improvement.)
Problem A, a little more specifically, the present invention makes it easy for the upper body to shake and become unstable while the care giver provides a power to assist the operation when the care receiver has difficulty standing and sitting in the bathtub Make it possible to support the care recipient at the same time. It is often difficult for caregivers to handle machines and motors in an elderly couple's home etc. Therefore, it is the most important task to provide care-ready equipment without using such external power at all. did.
Problem B: To minimize the number of parts, the small installation area, and the minimum installation work by devising a mechanism that is as simple as possible. The smaller the number of parts, the safer and more reliable operation for the carer and the carer, and because it can be maintained, it is a very basic thing, and it will not be necessary to explain much about the installation area and the amount of work. . The small installation area is the basis of organizing to maintain indoor space widely and to take care safely, and if the installation work is simple, it is possible to easily change or remodel care equipment according to restoration of the health condition of the care recipient. It also leads to things.
Problem C: To realize fundamental safety prepared for a fall etc. by taking care not to have heavy weight, bulky parts, sharp parts etc. on the head of the care receiver and carer. When it is absolutely necessary to place the head overhead, try to select a shape that is light and has rounded corners with few corners.
Problem D: As a basic design, the place to support the cared person's body by a pulley or rope so as to suspend is close to the end of the bath, not to the middle of the longitudinal direction. The body of the carer who is weak in the lower limbs sways back and forth, and if you try to solve it only with external power and a complete hanging care tool such as a chair lift, you have to be about the middle of the bathtub dimensionally. We devise there.
Problem E: The support member (harness) for supporting the weight of the care recipient is devised, and it is comfortable for the care recipient, does not bind or tighten, the support member does not clasp around the body during bathing, and at the same time in the bathing application Especially easy to wash the crotch you want to clean and fresh. In addition, it is easy for the care recipient to attach and detach the support member and to be easily connected to the suspension member.
In the present invention,
-Providing an auxiliary care tool that solves the specific individual problems of A to E, and-Providing a bathroom with a structure to which such a care instrument can be easily attached in the future.

In order to solve the above problems, a care tool according to the present invention is an auxiliary care tool for assisting a care recipient whose exercise capacity of a body including the lower limbs has deteriorated and a care giver who assists the care of the care recipient.
1. A rope-like member that transmits the carer's force to assist the movement;
2. A first fixing member for fixing one end without changing the direction of the rope-like member;
3. It can slide or rotate relative to the rope-like member while in contact with the rope-like member and change the direction of the rope-like member, and can receive the care while moving up and down in the vertical direction with the cared person's body A hanging member that holds a part of the weight of the elderly so as to be suspended,
4. A support member connected to the suspension member for supporting a part of the weight of the cared person to be suspended and contacting the body of the cared person;
5. It can slide or rotate relative to the rope-like member while contacting the rope-like member and changing the direction of the rope-like member, but its own center of gravity moves with the cared person's body And a second fixing member fixed in the room,
6. Attached near the other end of the rope-like member, the carer
A power point member for applying a force for assisting the standing and sitting motions of the cared person;
It is characterized by consisting of.
In the present invention, "caregiver's power" mainly refers to a force that helps moving the weight of the cared person in the vertical direction, that is, a force that aids in standing up and sitting.
In addition, “first fixing member”, “hanging member”, “second fixing member”, etc. do not mean only one piece of hardware or the like with which the rope contacts, but a flexible and strong relay rope attached thereto, It also includes a combination of a series of members such as a three-point set of ring-shaped hardware connecting the relay rope and the rope-like member.

The disclosure techniques of the portions referred to in Patent Literatures 1 to 3 shown in the Background Art section use most of the carer, even if he or she does not have the exercise ability to walk or keep standing up by himself. Instead, the care recipient begins to devise task extraction and solution means on the premise of being passive, but in the present invention such exercise ability of the care recipient is maintained weakly and it is utilized It assumes that. If you have the ability to walk a few steps slowly, walk slowly using a cane or walker, or hold on to the handrail and maintain the standing posture for a short time, the carer will be covered while taking advantage of that power. By devising a mechanism that helps the carer's standing up and sitting motions, it is possible to greatly simplify and reduce the weight of auxiliary care equipment.
Although the inventor actually takes care of elderly people whose physical abilities have fallen, the burden on the body is the greatest for both the carer and the cared person in the low posture close to sitting position among the standing and sitting movements of the cared person We focused on the fact that the operation was largely difficult. It is very difficult to get up from a sitting position with only one foot, so that healthy young people can easily simulate this, but once standing it is easy to maintain standing with one foot. Therefore, we decided to solve the low posture close to the sitting position preferentially, and consider it as a margin that lowers the priority and increases the design freedom, since it is possible to care enough from the middle and lower back to the standing position originally with less power.
In order to support the standing and sitting motion without external power, the carer must keep exerting a force of several tens of kg equivalent to the weight of the care recipient for a certain period of time. As it is impossible in the upper limbs such as the arms, it is reasonable to exert them in the lower limbs, and it is sufficient to incorporate a device that uses the "foot pressure" that can use natural gravity.
Furthermore, in many cases, it is overwhelmingly the case that elderly men are physically weak and their wives take care of themselves, and women who are relatively heavy are cared for by relatively light women. A force mechanism is also necessary.

Based on such an idea, in the present invention, the basic structure was examined based on the principle of the pulley and the estimation of a simple trigonometric function.
By using a moving pulley, even a 40 kg carer can ideally balance with a 80 kg carer (Figure 1). However, the carer and carer must stand up side by side with the principle of the moving pulley where the rope hangs straight down, and three members of the pulleys are near the head of two people, so I want to change the position for safety Furthermore, since the two fulcrums are close to each other, the load is concentrated on one place on the wall, so we would like to distribute the arrangement. Therefore, the fulcrum (hereinafter, also referred to as a fixing member) such as a fixed pulley is assumed to be separated from the left and right (FIG. 2 a), temporarily assuming that it is the upper part near the bathtub angle. In an average bathroom, the short side of the bathtub is 80 cm, the height difference between the bathroom and the bathtub is 15 cm, and the ceiling height of the bathroom is about 220 cm. Assuming that the care recipient is 170 cm tall, the sitting height is 85 cm, and the carer weight is 40 kg,
Calculation number 1 (FIG. 2a): When the fixing member is fixed near the ceiling, the rope opening angle 2theta_1 = 2 * tan at the action point (hereinafter, also referred to as a suspending member) since it is 150 cm from the head to the fulcrum It becomes ^ -1 (40/150) and cos (theta_1) = 0.97 at this time. In other words, the efficiency of the force in the vertical direction can be maintained at a sufficiently high value of 97% (the loss is 3%, neglecting the loss such as friction here) because the fixed pulley and other fixed points are separated to the left and right. Even a carer can help to stand up 2 * 40 * 0.97 = 77 kg of carers. For reference, the V-shaped opening angle of the rope at this time is about 2 * 15 = 30 degrees.
In fact, at this time, the care recipient is sitting in the bath, so buoyancy helps, and the upper limit of the real weight is 77 kg or more. In other words, the practical margin is large.
Trial calculation 2 (Fig. 2b): Similarly, in the standing position in the bathtub, it is 65 cm from the head to the fulcrum, so the rope opening angle at the point of action becomes approximately 2theta_2 = 2 * tan ^ -1 (40/65). Theta_2) = 0.85. That is, even if the cared person stands up and the V-shaped opening angle of the rope is increased, the efficiency can still be maintained at 85%. Even if the care recipient suddenly loses balance in the standing position, if the weight is 2 * 40 * 0.85 = 68 kg, it can be balanced with the weight of the 40 kg carer. If the patient does not lose balance, the carer is almost standing with his own power, and the carer can divert sufficient care power to the care operation 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.
The mounting height of the fixing member is preferably at least higher than the height of the care recipient, ideally close to the ceiling, due to the use of the pulleys. Generally, it is about 190 to 220 cm high from the floor of the bathroom. It is desirable to make it as high as possible in order to reduce the loss of the carer's power.

Furthermore, the care device of the present invention is particularly effective when applied to a bathroom where the sitting position of the care recipient is low. In that case, when the fixing member of the auxiliary care tool is attached, at least one of the two short sides of the rectangle when the bathtub in the bathroom is substantially rectangular in plan view. It is preferable that the first fixing member and the second fixing member be fixed to the upper side. 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 second fixing member is at the center side of the bathroom, it is easy to secure the attachment point of the power point member to which the caregiver applies the force and the operation place of the power point member below.
In addition, the first fixing member forms one end (starting end) which always stops and supports the end of the rope-like member, that is, it is only necessary to be stable while facing the cared person's body and thus rope-like There is no need to have the function of changing the direction of the members.
The second fixing member is in contact with the rope-like member, changes the direction of the rope-like member from the care receiver's body to the force point member, and reduces the transmission loss of the carer's force as much as possible. The second fixed member itself is fixed in the room without moving with the cared person's body because it moves so as to slide or rotate relative to it, but functions as a fulcrum so as to act as a fulcrum. A pulley or carabiner is preferably used as the second fixing member to be actually used.
These configurations lead to the solution of the problems A and C.

The mounting positions of the first fixing member and the second fixing member according to the present invention are fixed at positions along the same wall near the end rather than near the center when viewed in the bathtub long side direction. In this way, the first fixing member on the far side of the bathtub is attached near the corner where the strength of the two walls and the ceiling surface is high, and the second fixing member on the center of the bathroom is attached on the wall . Since it is easy to devise a construction in which the fixing member is pressed and fixed to the corner portion and the wall surface, it is convenient for stably fixing and maintaining the fixing member, and at the same time, the construction work for reinforcement purpose can be reduced.

What is more important is that by taking this arrangement, fixed members such as fixed pulleys will be brought closer to the end in the direction of the long side of the bath, and this position should be matched with the one on which the body is placed during normal bathing The person who is in the sitting position is in a position where it can easily lean on the bathtub, and in the standing position the bathroom wall and the care recipient's back position are close, so even if you lose balance as you turn backward, the wall surface. Will support you. In other words, the caregiver does not have to worry about the patient's back fall. Thus, fixing the fixing member at a position along the same wall surface in the room is preferable for the operation of nursing care, and it becomes more rational by approaching the end in the longitudinal direction of the bathtub.
In addition, although "a position along the same wall surface" means approaching to the same one wall surface among wall surfaces surrounding a room, the proximity distance is in a contact state 0 cm or about 15 cm apart so as to float slightly It should be at a distance of That is, the fixing members do not have to be always in contact or in close contact with the same wall surface.
This leads to the solution of the problems D and B.

  At least one of the first fixing member and the second fixing member may be fixed by an auxiliary post attached to the room. Each fixing member must ensure sufficient mounting strength to support the weight of the care recipient, but in the case of a general FRP unit bus etc., it may be difficult to secure the strength only by drilling and screwing . Also, it is difficult to drill holes while minimizing damage to the walls in tiled and mortar-finished bathrooms. Therefore, it is effective not only to perform fixation with the support column, but in the future, when the lower limb motor function of the care recipient recovers and the auxiliary care tool becomes unnecessary, the scratch etc. remaining in the room is minimized and removed cleanly. can do.

The auxiliary support may be longitudinally split and / or foldable. This is because the transportation, assembly and disassembly of the members are facilitated. The auxiliary support may be more than 2 m in size, while the bathroom and the area near the entrance are often narrow or bent, which is a common practice in a house. Moreover, when the existing handrail, water pipe, etc. are fixedly attached near the bathtub, there may be dimensional interference during the installation work of the auxiliary support. Furthermore, when utilizing the nursing care equipment according to the present invention in visiting care, it must be easy to transport by car. In consideration of these matters, it is desirable that the auxiliary support column be divided, folded, or a combination thereof in the longitudinal direction, and be able to be miniaturized to about 1 m or less at the stage up to the assembling operation.
Since a large external force is not applied to the relay member for making it split or foldable, there is no need for a special heavy-duty metal, batting or splint. As will be understood from the examples described later, the main force applied to the auxiliary support is a compressive force parallel to its longitudinal direction, and not a perpendicular (lateral) direction in which a tensile force or a shear force acts. Simple hardware can be used.
The size of the auxiliary supporting column material, which is shortened by division and folding, may be about 1 m or less, and division and folding may be realized by two divisions or two steps (one diffraction). If necessary, a structure of three divisions or three steps (two diffractions) or more may be used, or a combination of division and folding may be used.

The auxiliary support may have an extension mechanism in the longitudinal direction and be adjustable in length. This makes it possible to standardize the length of the auxiliary support to a typical length, and at the time of the individual installation work, the difference in length can be adjusted at the installation site, thereby facilitating the construction and at the same time It also contributes to the stabilization of quality because it is easy to maintain the work level for each work above a certain level. Furthermore, standardization of the length of the auxiliary support leads to a reduction in member cost.

The support member works to suspend a part of the weight of the care recipient, but at that time the hip joint which is lower than the waist of the care recipient and the lower part of the shoulder joint contact the care recipient's body. good.
The hip joint is the strongest among the joints of the human body, and is located near the center of gravity of the person. Therefore, even if the support member weakens the physical strength if the hip joint is supported, the care recipient is painlessly Moreover, it becomes possible to support weight stably. When the support member is put on the hip joint, the support member is put on even after sitting in the bath, but since the crotch is not covered, there is no hindrance to the original purpose of the bath where you want to clean the body.
The support member may be mounted to support the heel portion. The heel portion, i.e., the shoulder joint is also sufficiently strong and higher than the center of gravity of the person, so that it is possible to stably support the cared person's body without pain. When the support member supports the heel compared to the case where the hip joint is supported, it is natural for the cared person to hold the support member by hand, thus providing a natural posture and a configuration with a sense of security for the carer. You can do it. After sitting in the tub, it is easy to temporarily remove the support member from the coffin or to put it on the coffin again, so it is possible to devise a usage that does not interfere with bathing at all.
As compared with the case where the support member is put on the hip joint, such an arrangement for supporting the heel part is suitable when the physical strength of the care recipient remains stronger. On the contrary, if the exercise ability to maintain the physical strength and posture of the care recipient is very weak, it is also effective to support both the hip joint and the heel with the support member. It is possible to support a carer who tends to be unstable more stably and painlessly.

Ideally, the support member is pre-mounted on the care recipient's body. According to the results of various trial manufactures in consideration of easiness of installation, easiness of washing, etc., it is possible to make two thigh-stitched ones with a strip-like towel material of about 10 to 40 cm in width or a soft material of nylon. It is good to wear it in a pinch. The length of the ring is appropriately adjusted according to the physique of the care recipient, but the circumference is preferably 90 to 180 cm. In the case of hip joint support, the height of the carer is about half, and in the case of support on a heel, half of that is about half. Such a member is called an annular harness in the present invention.
In the present invention, since the two annular harnesses are worn in such a way as to be worn in the thighs of both feet of the carer or under the arms, the crotch is not covered, making it easy to wash such a part during bathing. ,convenient.
A part of the annular harness is connected to the suspension member to suspend a part of the weight of the care recipient, but in order to perform the operation to be connected to the suspension member quickly and reliably, the support member and the rope-like member It is good to put on a loop of similar rope material (Figure 3a, 3b). Alternatively, it may be a method of attaching a loop of connecting rope to the suspension member, and a method that is easy for the caregiver to handle may be appropriately selected.
Thus, the task E can be solved.

The hanging member is slidingly or hooked on the rope-like member and changes the direction of the rope-like member from V-shaped towards the second fixing member towards the second fixing member. And although it moves so as to slide or rotate relative to the rope-like member so as to minimize transmission loss of the force of the carer, it functions as a point of action, so the center of gravity of the suspending member itself Move vertically with the person's body. It is supported to suspend part of the carer's weight, and the remaining weight is supported by the carer's own foot. A hanging member to be used in practice is a C-shaped ring, a hook-shaped hardware, or the like, which is easily selected to easily carry out the attaching and detaching of the supporting member as described above. Carabiner is originally because the material, structure, and finish are optimized in order to operate with the rope by human hands. It is also effective to use a pulley to reduce the loss of power transmission by the caregiver.

In the vicinity of the other end of the rope-like member, a power point member is attached which applies a force for the carer to assist in the standing and sitting motions of the care receiver.
In the device of the power point, in order to convey the "force to step on with foot" that can use the weight of the carer naturally with the gravity of nature, I tried to solve by making "Abumi". The core should be made of the same rope as the rope member, but if it is in the form of a rope, it may hang down and the shape may not be determined, so it may be difficult to put a foot on it. Therefore, the opening of about 10 to 15 cm can always be maintained through the resin tube. In the trial production, a general water hose was cut into an appropriate length, but there is adequate friction, sufficient strength, inexpensive materials, and practically good results are obtained. There is. (Figure 4)
Although the interval and the number of steps of the dumplings may be adjusted appropriately according to the physique of the carer, the interval is about 20 to 30 cm, and the number of rows is 85/20 4 4 considering the difference between the height and the sitting height assumed in paragraph 12. It is good with around 5 steps, and it is getting good results with it even in actual trial production.
A dumpling-like 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 point of force is further added. This is because “the gap time of the force at the time of change, discontinuous force” may occur with the absumi alone described in the previous paragraph, and the force to support the care recipient may be interrupted. This problem is not always unique because it depends on the height of the gap and the exercise capacity of the carer's leg.
By the way, in order to solve "the gap time of the power at the time of change, discontinuous power", a round bar (hereinafter referred to as a friction grip hand near the tub edge separating the care receiver on the bathtub side and the care worker on the washing place side). Attached (also referred to as a member). The most ideal position is the vertical longitudinal ideal on the line connecting the fixed member near the center of the bathroom and the sheet. As a result, the rope and the friction grip hand member can be brought close to each other. The caregiver can create adequate friction by holding together the rope and the friction grip (or pushing the friction grip over the rope). The frictional force is unexpectedly strong and sufficient to support the weight of the care recipient.
The mounting height of the friction grip hand member should ideally cover the height range from the waist to the face of the caregiver in order to make it easy for the caregiver to control the friction braking force. On average, it is convenient that the lowest part of the friction grip hand member is about 60 to 80 cm from the floor and the highest part is about 120 to 150 cm from the floor. Even if the installation direction can only be horizontal for some reasons, the installation height should be in the vertical (vertical) numerical range (about 60 to 150 cm from the floor surface). As a material, in the case of a bathroom, it is preferable to use a stainless steel, a robust resin, or another metal as a core and resin coating treatment, but when applied to other rooms, wood is sufficiently practical.
The practical attachment position of the friction grip member is approximately directly below the second fixing member, or within 25 cm of a horizontal distance even if it is largely deviated, in a typical example in which the longitudinal attachment is near the bathing entry / exit edge of the bath. good. If the mounting position of the friction grip member and the mounting position of the second fixing member are adjusted relative to each other so that the displacement is about 25 cm, the rope-like member passing through the second fixing member follows the immediate vicinity of the friction gripping member The load point member is in the state of hanging down below the position. The caregiver operates the rope-like member and the friction grip hand by hand, operates the power point member with the foot, treats them in combination, and allows the cared person to be slowly seated in the bath or temporarily stopped halfway Or you can arrange a very convenient arrangement to get it up. The combination of the hand, rope, and friction grip hand members as needed (the combination depends on the skill of the carer) will help the care giver to stand and sit. Moreover, since the expression of body weight and friction is sufficient with the action of only one foot and / or one hand, the remaining one foot and one hand (mostly two hands in many cases in practice) can be freely used during care such as bathing. Therefore, while supporting the weight of the care recipient, it is possible at the same time to add a hand so that the upper body of the care recipient does not shake in the horizontal direction and does not become unstable.
When it is desired to perform a temporary stop during operation for a long time, there is also a utilization method such as tying or hooking the rope-like member to the friction grip hand member for temporary fixing.
In this way, it is possible to provide a lightweight, small-footprinted, low-cost auxiliary care tool without the need for an external motor such as an electric motor or a pressure cylinder, mechanical parts such as a gear or a ratchet mechanism, etc. There is a set of practical means.

It is possible to attach such nursing care equipment in the bathroom in post-processing or retrofitting without major reinforcement work as described in the previous stages, but preparations are made in advance so that future installation work will be almost unnecessary. If this is done, it is not necessary to use a retrofit auxiliary post, etc., and it may be clean in appearance, and it is also possible to secure sufficient strength.
In the present invention, it is a bathroom for facilitating attachment of an auxiliary care tool for assisting a carer whose physical ability including the lower limbs has deteriorated and a carer who assists the carer in standing up and sitting.
1. At least two mutually spaced apart anchor members for mounting a fixing member which supports and / or relays the carer's force assisting in the standing and sitting movement of the cared person,
2. The positions of the at least two mutually spaced anchor members are:
Among the two short sides of the rectangle, when the bathtub is substantially rectangular in plan view, it is above both ends of at least one short side,
Provide a bathroom designed and manufactured as follows.
The two mutually spaced anchor members need only be strong enough to support the weight of a person and not the machinery, so no special reinforcement in design and fabrication is necessary, and the design size and manufacture of the bathroom The impact on installation costs is very small and reasonable.

According to the present invention, the carer can exert a force to help the cared person stand up and sit with one foot or so, so the extra limbs support the cared person's body in the horizontal direction, etc. It can be used freely. Since the position of the caregiver can be kept standing, the posture of the caregiver can be very easy. It is effective to reduce the burden on caregivers, especially in places where the position of the care recipient is low, such as in a bathroom. Moreover, since it does not require an external power such as a motor or a mechanical part such as a ratchet, it can be easily retrofitted in many cases because it is lightweight, safe and has a small installation area. In addition, by devising to attach such a nursing care equipment at the time of design and manufacture of the bathroom, it is possible to prepare for the nursing care equipment installation easily and inexpensively.

Hereinafter, features of the present invention will be described with reference to examples.
Example 1 is a care tool designed in a case where two elderly couples live while helping each other. The weight of the husband, who is the care recipient, is about 60 kg, and the weight of the husband, who is the caregiver, is about 40 kg. The bathroom is a unit bath made of FRP, and the floor dimensions of the bathroom are as shown in Figure 5 and Figure 6 (unit mm in the figure, the parts overlapping each other making the parts difficult to see are simplified). The height is as small as about 2190 mm.
The care recipient who has an arrangement that is easy to hold onto wall surfaces and handrails (only a part of multiple handrails is shown in the figure, etc.) including movement from the undressing room (not shown) and bathing. She could not stand up on her own even if she held the handrail, and she was taking bathing care with her husband and helper. In addition, the bathroom and the dressing room and the aisle leading to it are bent, so there is no space for attaching a crane-like support mechanism, and it is not a house that assumes installation of a crane-like structure before that. The frame strength of the building is lacking in the first place.

There is a gap of 100 mm or more between the unit bus wall and the wall of the house body, so there is room for processing work, so the fixing member is attached to the anchor hardware, and the anchor hardware is the toggle bolt and epoxy resin elastic on the FRP wall of the bathroom. It fixes using an adhesive agent (EP001N by Cemedine). Since there is no hand on the back of the unit bus wall, a reinforcement block can not be used, but if possible it is better to perform reinforcement treatment from the back.
A hole can be made in the bathroom wall 50 to 100 mm lower than the ceiling, and two anchors can be fixed using four toggle bolts and an adhesive (details such as bolts are not shown). The two anchors are separated by about 800 mm from each other in the front, back, left, and right positions, just above the corner on the bathtub head side. In this position, even if an item or the like comes off and falls, it does not hit directly because it is outside the shoulder width of the care recipient.

Attach an annular relay rope (about 100 mm in diameter) to the anchor hardware on the back side of the bathroom, and attach a gated key ring (a spring-loaded, aluminum bracket that opens and closes a part of the ring) about 50 mm in length. There is no static load indication on the key ring. The relay rope and the key ring form a first fixing member (5e) (see FIG. 7).
On the other hand, a pulley is attached to the anchor metal on the left side of FIG. 6 as a second fixing member (5f) via a relay rope. The car part of the pulley is made of resin of unknown material, and the other part seems to be made of stainless steel (due to its poor texture and adhesion to the magnet). The static load indication shall be 65 kg (which seems to mean exactly 65 kgf).

The rope-like member (5r) is a slippery, soft and flexible nylon rope with a diameter of 5 mm so as not to feel pain. The nominal static load is over 700 kgf. One end of the rope-like member (5r) is connected to the gated key ring which is a part of the first fixing member (5e), and the middle part is passed through the pulley of the second fixing member (5f).
As a hanging member (5s), a stainless steel C-shaped ring with a material diameter of about 5 mm is hooked on the rope-like member (5r) near the middle between the first fixing member (5e) and the second fixing member (5f) hang.

The support member (5h) is prepared by sewing two towels (Fig. 3a, 3b) into a ring, and an annular harness such as nylon rope is bundled into one to make a ring harness (Fig. 3a, 3b). Advantageously, by bundling nylon ropes in one piece, the operation to be hung on the hanging member (5s) can be done only once at the time of care. In addition, it is more convenient to bundle two bulky towel cloths and pass them through the hanging member (5s) because they are dimensionally impossible, and it is preferable to bundle them together with an annular rope or the like.

As shown in the photograph in FIG. 4, the force application member (5p in FIG. 6) is a “globular” or “ladder-like” at intervals of about 20-30 cm while passing the rope-like member (5r) through a flexible vinyl tube. It was connected in several stages so as to become In order to prevent the vinyl tube from sliding in the longitudinal direction, it may be temporarily fixed to the rope-like member with an adhesive or a sewing thread.

The handgrip is attached to the head of the bathtub, near the upper edge of the bathtub (see FIG. 6) and a commercially available bathroom handrail (5 g). The mounting position was designed to be 20 to 30 mm away from the bathtub directly below the second fixing member (5f), avoiding FRP panel joints (not shown).
In this embodiment, although the anchor and the grip member described at the beginning are retrofitted, it is easier to attach reinforcements etc. originally when installing the bathroom in advance (when building a building), and it is possible to install the bathroom before shipping It is more desirable because it can be installed easily and reliably at the factory.

A mode when using the auxiliary care tool of a present Example is shown by FIG. 8 and FIG. 9 in a schematic diagram (The description of the member etc. common in FIG. 5, FIG. 6 is abbreviate | omitted).
Before entering the bathtub, attach an annular harness to both the thighs of the care recipient (5a) in such a way as to put on clothes. The rope having the annular harness bundled may be hung on the hanging member either in the order before or after the care recipient enters the bath, and in the order that the caregiver can easily operate.
The carer (5b) holds the rope so as to hold it to the handrail and at the same time steps on the goose-like force point member, which makes it possible to double the weight of the cared person. It is sufficient to hold the rope with one hand (in Fig. 9 placement, the left hand) and one foot (in Fig. 9 placement, the left leg) to step on the bump, and the remaining free one hand and one leg (right hand・ The right foot) can be used freely to help the caregiver step on and the caretaker's posture is unstable. Furthermore, when the position of the care recipient is stable, the strength is sufficient simply by stepping on the bite-like force point member, so that both hands and one leg are free, and care can be performed very easily.
When the cared person sits down from the standing position, no sting is usually required, and the carer need only loosen the force holding the rope against the handrail to slide the rope, and it is easy to adjust the friction braking force.
When the care recipient stands up from a sitting position, the carer may step into the abscissors or withdraw the abscissors (which are then at a high position) by hand. The principle of moving pulleys produces nearly twice as much power, and the carer's posture that produces power can be kept in a natural standing position, so the burden on the carer is greatly reduced.
Before the implementation of the present embodiment, both the wife and the helper work hard to take a bath every 1-2 days, but after the implementation of the present embodiment, only one wife can perform daily bathing, It can be expected to help improve the hygiene and circulation of the care recipient.

The parts necessary for the present embodiment are the following nine points.
・ Anchor: 2 pieces ・ Auxiliary support: 0 piece ・ Fixed member: 2 pieces (relay rope and key ring, relay rope and pulley)
・ Rope: 1 (5 mm diameter nylon braided rope)
・ Hanging member: 1 piece (stainless steel C type ring)
・ Supporting member: 1 (ring harness)
・ Power point member: 1 (make a stirrup collectively on the extension of the rope)
・ Grip hand member: 1 (commercial bathroom handrail)
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 another portion or may be fixed by providing a plurality of anchors on two or more surfaces. If there is no appropriate structure for mounting the fixing member on the same wall surface, it may be an adjacent wall surface or a ceiling surface, or may be fixed to an auxiliary support post-mounted indoors.
In an actual indoor structure, especially in a bathroom such as a unit bath, there may be cases where the appropriate structure or strength for attaching the fixing member can not be obtained, or because it may not be desirable to drill a hole for anchor attachment on the wall. You can use

The backup plan considered in the same case as the first embodiment is the second embodiment. In order to reduce the number of holes in the wall of the bathroom and to prepare for the case where it is difficult to make such holes by the material room of the bathroom wall, this embodiment uses one auxiliary support.

The auxiliary support (10 w) was installed diagonally and diagonally along the wall surface so as to be stable in the left and right direction of FIG. In order to prevent the concentration of force on one narrow point on the bathroom wall, etc., to prevent slipping, and to prevent the supporting column timber from being corroded by further wetting with water, a backing plate is used. The cork board is used for the upper left corner part of FIG. 10, and the rubber plate for buffer is used for the lower right. A through hole is made in the vicinity of the upper end of the auxiliary support, and a relay rope is tied there and a gated key ring of about 50 mm in length is attached as in the first embodiment. In this case, an auxiliary support with a through hole serves as an anchor member. The support post bears a part of the weight of the carer in the length direction, and the remaining weight is supported by friction with the wall. The timber may be light and thin since no other external force such as bending of the support post acts. Here, cedar wood with 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 support with a total length of 1920 mm.
When the position for providing the support post is in this way along the inner wall surface of the bathtub, it does not interfere with daily bathing. When applied to nursing care to help getting up in a bedroom other than a bathroom, a fixing method such as a two-point set in which a rope for fixing is wound around a structure such as a barrier or column and connecting rope-like members via ring-shaped hardware You can devise In addition, when applying to a toilet, the fixing member can be attached by appropriately combining a strong indoor structure such as a shelter and an auxiliary support.
The anchor at the upper left of FIG. 11 is used as an anchor after retrofitting a commercially available shower curtain attachment. In addition, since there is a possibility that the auxiliary support can fall to the left in FIG. 11 as it is, it is configured to support the shower curtain attachment with a commercially available push rod. There will be about 150 g of a stick above the care recipient's head, but since it is light and has no corners, and the end has a rubber cap, there is a safety problem if the stick falls. I do not think that.

Further, FIG. 11 also shows how the support member is supported so as to be in contact with the body at the heel portion of the cared person.
As a support method of the care receiver by the support member, in another comparative examination, a towel manufactured by sewing in a slightly longer ring than in the case of Example 1 is wound on the chest and the carer's body is taken over the entire rib. We made a trial evaluation to support the His chest tightness seemed to be unexpectedly strong, and the trial was interrupted because he complained and felt pain for the care recipient.

The other points of this embodiment are substantially the same as those of the first embodiment, but the movable portion of the pulley used for the second fixed member (10f) is not only an axle (a direction perpendicular to the force of load, so-called X axis) but The neck part that hangs the pulley (a sort of Z axis parallel to the force of the load) is also selected to rotate, and it is designed so that the pulley shakes its neck and follows the direction of the rope even if the direction of the rope changes. It is easy to obtain the static load indication of 65 kg and so on. However, even if the neck part that suspends the pulley as in Example 1 does not turn, since the relay rope absorbs twisting, almost no stress should occur in the entire tool. Besides the pulleys, it is also effective to use a carabiner for the second fixing member. In this case, friction is a little large, and there is a demerit that loss of the power of the carer increases, but conversely, if the friction is used, the friction of the carpenter's weight supporting the carer or the friction of the rope with the grip hand member The merit of reducing the burden of braking is born.

As a hanging member, a carabiner of about 10 mm in thickness and about 100 mm in length is used. A pear-shaped aluminum alloy carabiner or the like is suitable, and it has a shape and finish (it has a gentle chamfer and almost no corners) originally adapted to human hands, and is shaped so as to increase the radius of curvature of the rope application portion There is an advantage that the device is made, the friction with the rope is sufficiently small, and the damage to the rope is also small. In order to further reduce the friction with the rope, it is sufficient to use a pulley for the suspension member, but when compared with the prototype device, there was no difference so as to feel a special lightness.

The usage of the auxiliary care device of this embodiment is the same as that of the first embodiment. In this case, after comparative explanation of Examples 1 and 2, Example 2 which does not have to be drilled on the wall surface is temporarily attached and it is confirmed that care can be performed easily by the force of a light weight husband. did it.
The parts necessary for the present embodiment are as follows:
・ Anchor: 1 piece ・ Auxiliary support: 1 piece (approximately 1920mm in length)
・ Supplementary material: 3 (cork board for shock absorption, rubber board, pinch rod)
・ Fixing member: 2 pieces (relay rope and key ring, relay rope and pulley)
・ Rope: 1 (5 mm diameter nylon braided rope)
・ Hanging member: 1 piece (aluminum alloy carabiner)
・ Supporting member: 1 (ring harness)
・ Power point member: 1 (make a stirrup collectively on the extension of the rope)
・ Grip hand member: 1 (commercial bathroom handrail)
In addition, what is necessary is just to invert the whole symmetrically, when the arrangement | positioning of a bathtub (the direction in which a head and an upper body are usually placed) is opposite in Example 1 and 2 or a care worker's dominant arm is reverse.

In the present example, comparison and examination of the material of the rope-like member to be used and the knitting method were conducted.
As materials, nylon, polypropylene, vinylon, polyester, polyethylene, or some of these mixed materials were compared. The way of knitting was "triple hit" in all cases, but the material comparison was made, but nylon and polypropylene were soft and slippery, and they were good in water breakage. There is a problem that the vinylon is difficult to loosen when it is entangled, probably because the friction between the ropes is a little large, and the water retention is good and the water does not break well after being used in the bathroom. Polyester is not adopted this time because it does not routinely perform tying / loosening because polyester has a little friction between ropes and is not as smooth as nylon. In addition, in this comparative study, there is a problem that there are few samples available and the range of selection is limited. Polyethylene has a very hard texture and feels somewhat painful on the hand, and therefore, the friction with the handrail is small and difficult to control, which is not suitable for the purpose of the present invention. From these comparisons, two types of materials, nylon and polypropylene, were selected.
The comparison of the rope knitting method compared with the readily available knitted rope and triple strike, but excellent in softness, difficulty in tangling, and ease of control of friction when held on the handrail It turned out that a braided rope is suitable. In addition, it seems that there are several names in the way of knitting, and the thing of a knitting rope seems to be also called a hammer.
As nylon braided ropes are available in various sizes on the market, comparisons of 4 to 8 mm in diameter were also conducted. The diameter of 4 mm is a little too thin and you may feel a little pain when operating. If it is 5mm and 6mm, there is no problem with a reasonable operability. Although 8 mm may be sufficient, there is no special merit such as excessive strength in excess of what is necessary, resulting in excessive specification in terms of load capacity, and long time taken for drying after being wet with water.
Finally, the comparative study of nylon braided bands (width 10, 20, 30 mm) was conducted, but the band material is as good as nylon braided rope in terms of softness and entanglement, and when grasped on the handrail The band width of 20-30 mm was good in order to control the friction of the frame moderately. However, in the case where a pulley is used as the second fixing member (7f), the size (width of the car) is matched to the band, resulting in a disadvantage that the size of the pulley and hence the price become very high. On the contrary, there is an advantage that it is easy to make a strong knot, for example, when manufacturing abumi.
From the above results, it was decided to use nylon braided rope or polypropylene braided rope with a diameter of 5 to 6 mm.

The fourth embodiment is an example designed in a case where two elderly couples live together while helping each other to live with each other. The weight of the husband who is the care recipient is about 70 kg, and the weight of the husband who is the caregiver is about 45 kg (details unconfirmed). It becomes difficult, and a family is helping two people stand up. The bathroom is tiled. The floor surface dimension which shows a part of bathroom in FIG. 12, FIG. 13 is about 2 m in height and width.
There is space in the bathroom and approach to that, but because the finish is tiled, to attach a mechanism like a crane-like support mechanism or a robot arm, remove concrete and mortar once and restructure the foundation This is a large-scale case because it is necessary, and it is a case that is also in trouble including the cost side.

In this embodiment, the indoor clothes drying rail (12i) and the handrail (shown as a 12g grip hand member in FIG. 12) are already attached to the bathroom. Among them, the indoor clothes drying rail (12i) is strong, but its position is approximately midway viewed from the rectangular bathtub (12t) short side direction, and it is about 30 cm away from the tub edge, so as a second fixing member attachment It is difficult to use. The reason is that there is a member such as a pulley above the head when taking a bath, and there is concern about safety, and it can be seen in FIG. 13 that the cared person's body is far from the bathroom left in the figure, that is, the carer. And become stable.
Therefore, in this case, it was designed to use two auxiliary columns, 12w auxiliary column-1 and auxiliary column-2. The auxiliary support 1 is placed obliquely along the wall on the far side of the bathtub, and inserted into the inside of the handrail 1 to prevent the auxiliary support 1 from sliding to the left in FIG. Further, when viewed from the direction of the short side of FIG. 13, it is designed to support and hold the pulling rod between the indoor drying rail (12i) so that the upper side of the auxiliary support 1 falls to the right in the figure.
The support post-2 is erected straight from the floor surface using a thin plate-like wood, and fixed using a handgrip (12 g).
The attachment of the first fixing member and the second fixing member to the auxiliary support 1 and the auxiliary support 2 (12 w) is performed in the same manner as in the first and second embodiments. Although a pulley is used as the second fixing member (12f), it is possible to change according to the caregiver's request.

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

The support member (not shown) is an annular harness made of a towel, nylon band, webbing material, etc., which has a good touch, and has a ring that is easy to wash and dry. There is no change in the basic structure that supports the weight of the patient's thighs.
In addition, it may be possible to cope with care such as lifting the entire body by replacing the lower limbs of the care recipient with one hammock-like member supported by the hips instead of both hip joints as needed.

The force application member is integrally formed on the extension line of the rope-like member in the first and second embodiments, but is divided from the rope-like member in the present embodiment. The point at which the rope-like member (12r) and the force application member (12p) are connected is near 12j in FIG. The connection is made with the key ring in the same manner as the attachment of the fixing member. By dividing into two parts, it becomes easy to carry out the maintenance and the like, such as removing and disassembling the auxiliary care tool by inspection of the abumi and the pulley, or replacing it with another one. In addition, if the position of the connection point is properly adjusted, the key ring gets caught in the narrow passage passing the rope to the second fixing member (pulley) even when the caretaker slips the rope carelessly, and the care receiver gets fierce It also plays a role in preventing such failures. In the present embodiment, two types of step shapes of the fillet were prepared, one having a triangular shape as in the first embodiment and the other having a semicircular or annular shape. After assembling the entire assistive device, compare which form of fistula is easier to use. There is a possibility that it is easier to put a foot on the annular shape than the triangular one discussed in the second embodiment, and the selection is made based on the result of the trial.

Further, in the prototypes of Examples 1 and 2, the force application members 5p and 10p rarely come close to the wall, which may make it difficult to apply a foot. In the present example, as shown in FIG. 14, a cup-shaped member (12 cup) (from the shape, it may be more suitable to say dome-shaped) was prepared. A cup-shaped member is attached below the grip member 12g, and it will be compared whether it is effective as a device to prevent the force-point member (12p) from coming too close to the wall.

  Another comparison in the present embodiment is the strengthening of the power for assisting the standing. In this case, the carer's physical size is large and the difference in weight with the family seems to be large, so it may be necessary for two people to operate the rope or the rope, especially when helping to stand up. Therefore, the members were arranged to be able to compare the operation by two carers as shown in FIG. Use this to confirm the effects and issues of two-person care.

The necessary parts in the present embodiment are summarized in the following 14 points.
・ Anchor: 0 piece ・ Auxiliary support: 2 pieces (Auxiliary support -1 length approximately 2380 mm, auxiliary support 2 length approximately 2130 mm)
・ Supplementary materials: 4 (cork board for shock absorption, rubber board, pinch rod)

The use of the care device of this embodiment is similar to that described in the first and second embodiments.

In Example 2, in order to make it easy to divide and support a long auxiliary support (10w) for transportation and assembly, the two auxiliary support members are divided using an angle hardware (10j) and a through screw (bolt and nut, 16s). did. The division | segmentation * junction structure schematic diagram is shown in FIG.
In addition, as shown in FIG. 17, the structure to be folded by utilizing hinges (17h) and buckle-like hardware (general name unknown, 17b) is also transported and assembled, and the disassembling operation is easy and rational. The combined use of the split type and the fold type is also appropriately made according to the rationality of design, processing, and construction.
As a result of the division and folding structure, the length of one auxiliary support material is shortened. If the combination of two materials is applied to Examples 2 and 4 and the auxiliary support can be shortened to about 950 to 1200 mm with a total length of about 1900 to 2400 mm, it becomes a practical length that can be transported by courier or passenger car. . In addition to facilitating indoor handling at the installation site, in the case where it is inserted inside the handrail 1 described in the fourth embodiment, once the handrail 1 is removed, the approximately 2380 mm auxiliary support 1 (12w1) is temporarily removed. Although it was necessary to reattach the handrail 1 next to the mounting, there is an advantage that the number of operation steps is reduced because the handrail 1 does not need to be attached and detached. In the case where the auxiliary support 2 (12w2) described in the fourth embodiment is made of a material combination of two or more, since the place is originally easy to be installed, the effect on the operation man-hour is small. However, the advantage of ease of transportation and handling can be obtained as in the case of the support post-1.

In Examples 2 and 4, long auxiliary columns (10 w, 12 w, etc.) are cut in accordance with the dimensions of the bathroom each time, but it takes time to finish chamfering, rounding, painting, etc. of the cut at the installation site. In order to rationalize this point, the length of the auxiliary support may be standardized to a typical length, and a telescopic mechanism may be incorporated and adjusted at the installation site.
This makes it possible to maintain the work level of each work at a certain level or higher, and it is possible to standardize the length of the auxiliary support, leading to a reduction in the cost of parts.
An example in which the mechanism of length expansion and contraction adjustment is prototyped is shown in a schematic view in FIG. This trial manufacture is an element trial manufacture of only an auxiliary support part, not the whole auxiliary care tool. The end of the auxiliary support (corresponding to 10w, 12w, etc.) is cut, for example, to about 100 to 200 mm, and an insert screw (18i) is embedded in one material. An adjustment screw may be screwed into the other material and fixed by being filled with an adhesive or the like. The insert screw used was an oni nut E type M8 * 25 mm (available at Nakamura Shokai Co., Ltd.), but it may be selected as appropriate. Although the adjustment screw (18a) used was 100 mm, it may be appropriately selected. As a result, a telescopic mechanism has been completed which maintains sufficient strength to withstand the compressive load (in the case of the present invention, the weight of a person) applied in the direction of the length of the auxiliary support.
Although in FIG. 18 the insert screw is embedded in only one material, it may be embedded in both if necessary. Further, in FIG. 18, the shorter end cut into about 100 to 200 mm may be cut off in a trapezoidal shape and used on the upper side of FIG. 10 or 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, since water may be splashed in the bathroom, it is intended to prevent the insert screw and the adjustment screw from getting wet.
In addition, the screw structure of length expansion-contraction adjustment may serve as the joint structure of the divided | segmented auxiliary | assistant support column.

A comparison of the auxiliary support used in the second embodiment and the fourth embodiment with the auxiliary support incorporating the division, folding, and expansion / contraction mechanism as described in the preceding paragraph is summarized in FIG. The element trial production 1 is the result of element trial production of only the supporting column portion, and the same element designs 1 to 3 were conducted by desktop calculation.
In Element Prototype 1, the auxiliary support is divided into two 870 mm pieces of material, and it is composed of a total of three pieces together with the material embedded with the adjustment screw.
In Element Design 1, the auxiliary support was divided into 950, 790 mm 2 pieces of material. The length of the short auxiliary support material is 950 mm (= 790 + 160) in combination with the length 160 mm of the material fixed by filling the adjusting screw, and the same length as the longer auxiliary support material. It is better to have the same length when storing, packing, and shipping the materials for the preparation.
In the element design 2, the auxiliary support is divided into three 750 mm materials so as to have a length of 2350 mm after assembly, and a total of four are configured in combination with the materials embedded with adjustment screws.
In Element Design 3, the auxiliary support was divided into 1200 mm 2 pieces of material so as to have a length of 2400 mm after assembly, but no extension mechanism for adjusting the length was 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 tool of the present invention is characterized by a small number of parts and light weight, but by making further use of it, it is possible to assemble and disassemble in a short time at the use site, and it is also applied to visiting care It will be possible to
FIGS. 20 and 21 are diagrams showing such an applied design example based on the fourth embodiment, showing a side view and a front view, respectively. The basic structure of the auxiliary support is the same as that of the fourth embodiment, but the split / joint structure (20j1) (20j2) and the expansion / contraction mechanism (20a1) (20a2) are adopted so that assembly / disassembly can be performed each time in use. did.
Further, in the method of fixing the auxiliary column-2, instead of fixing using the handgrip member (12g) as in the fourth embodiment, a method of temporarily adding two struts and further temporarily fixing is adopted. In order to prevent the auxiliary support 2 from falling in the longitudinal direction of the bath, a strut bar -A (20c1, double upper wire in FIG. 20) is used at a high position parallel to the clothes drying rail (12i). Further, in order to prevent the auxiliary columns 1 and 2 from falling down in the front view left and right direction, the support rods -B and C (20c2, 20c3 upper double wire in FIG. 21) are used. The short tie bar used in Example 4 is not needed in this case. The split / joined structure part may be folded if necessary.
If the existing clothes rail or shower curtain rail is in a convenient position for attaching the fixing member, it may be temporarily fixed thereto by a clamp mechanism or the like. In that case, such a clamp mechanism may be provided in advance on the auxiliary support.
In this way, the care device of the present invention can be assembled and disassembled each time it is used, and can be easily used for visiting care and the like. The duration of assembly and disassembly may be on the order of 15 to 30 minutes, and the assembly can be completed while the bath is filled.

As another device, it is possible to standardize the length of auxiliary support and manufacture with aluminum material. For example, by combining a split / join or folding type and an extension mechanism as shown in FIG. 19, three types of standard length auxiliary posts of 2000 +/- 75 mm, 2150 +/- 75 mm and 2300 +/- 75 mm Can be made of aluminum material.
The structural schematic diagram (a part of spring vicinity is sectional drawing) is shown in FIG. As in the fifth embodiment, the auxiliary support is made of a split type using a joint metal or a foldable type in which a hinge and a buckle-like metal are combined to shorten the auxiliary support material (22j). A turnable angle adjustment mechanism (22a) is provided at both ends of the auxiliary support column to facilitate the angle adjustment work when obliquely erecting on the wall surface. Anti-slip and buffer rubber etc. are stuck on the bottom part. The telescopic mechanism can also utilize a method such as combining a length adjustment hole (22h) and a button (22b) as often seen with walking aids and the like.
Such a device makes it possible to streamline the fabrication of the supporting column, significantly reduce the number of assembling steps at the installation site, and make the assembling and disassembling work very easy even when used for visiting care. The cost can be reduced by combining with the support column length standardization.

In the above embodiment, an anchor for attaching the fixing member to the existing bathroom by post-processing or addition of an auxiliary support is provided. However, the anchor member as shown in the first embodiment is located at a higher position and a corner of the bathroom. It is necessary to set up, it is difficult to do the work, and even if you want to hit the backing reinforcement plate, it can not be reached, and it is difficult to do the post-processing. Then, it is desirable to attach an anchor member at the time of initial construction of a bathroom.
If it is an anchor member of a simple structure as shown in Example 1, even if ordering it at the time of the initial construction of the bathroom, it does not cost so much, so even those who are not concerned about the current physical function prepare for the future It can be attached.
The concrete shapes and structures of the two anchors are, in addition to the anchor hardware as in Example 1, the shower curtain attachment as in Example 2 as long as it is strong enough to support human weight, Example 4 It may be a rail for indoor drying such as. Parts such as shower curtain fittings and indoor clothes drying rails are often mounted and well known in conventional bathrooms but the conventional mounting position was only near the top of the bath front (washing side). In order to realize the present invention, it is also necessary to attach it also to the upper side of the bath back side (the back wall side). As shown in FIG. 6 etc., the short side upper end upper part vicinity of a rectangular bathtub is suitable as a left-right position.
A bar-like friction grip hand member (handrail etc.) may be retrofitted if necessary. This is because the friction grip hand member is not a part where a large force is intensively applied, so the need for backing reinforcement is low, and the mounting position is in the range of the height of a person, so that the retrofitting work is easy. Of course, it does not matter if you attach it at the same time as the anchor member at the initial construction of the bathroom, because the overhang from the wall is a few tens of mm round bar, it does not interfere with the usual bathing.

  By optimizing the member arrangement and structure of the auxiliary care device to be installed indoors, it became possible to support the operation of standing up, getting up, and sitting of the care receiver by the power of one carer. The carer is relieved of the heavy work of supporting the carer in a back and forth posture. It is excellent in safety because it does not use mechanical parts such as external power and there are no weight members on the head. It is easy to install and can be installed in the homes of old people and old homes. It can be widely applied to places such as a bathroom, a toilet, and a bedroom for caring people with impaired leg performance.
