Description

The present invention is a standing-sitting assistance device that assists in standing-and-sitting movements of a person who is difficult to stand.

The person who is difficult to stand by assuming the present invention is assumed to be an elderly person whose body muscles are weak, a person who becomes physically disabled, etc. There is a prior application like this.
For example, Japanese Patent Application Laid-Open No. 2001-276164 provides a bath with a structure in which a seat that can be raised and lowered at the end of a bathtub is provided at the upper end of the bathtub, and a user is seated on the seat and the seat is raised and lowered in an arc shape in the bathtub. It is a device to assist. (See Patent Document 1)
Japanese Patent Laid-Open No. 10-192359 raises and lowers a seat along a support column provided perpendicularly to the side surface of the bathtub. (See Patent Document 2)
Both of these perform an auxiliary operation for bathing the user with the device, and the user can take a bath without using any force for the bathing operation as long as the user sits on the seat of the device.
Japanese Patent Application Laid-Open No. 2002-153390 makes it possible to bathe safely by holding the grip with both hands by constructing the handrail of the bathtub with two parallel grips, so that the body can be lowered. It is something to do. (See Patent Document 3)

Japanese Patent Laid-Open No. 2001-276164 (page 3, FIG. 1, FIG. 3) JP-A-10-192359 (2nd page-4th page, Fig. 1) Japanese Patent Laid-Open No. 2002-153390 (page 3, FIG. 1) Japanese Unexamined Patent Publication No. 2002-65766 (5th page, FIG. 1)

Patent Document 1 (Japanese Patent Laid-Open No. 2001-276164) and Patent Document 2 (Japanese Patent Laid-Open No. 10-192359) describe bathing without requiring any user force as long as the user sits on the seat. Even if the user can be assisted, the user does not use any power, so there is no rehabilitation effect, and the muscle strength of the hands and legs is not used. Bathing just sitting on these seats is easy, but those devices are large-scale and disturb the bathing of a healthy family member, and muscle strength declines because the muscles of the user's hands and legs are not used I must.
Patent Document 3 (Japanese Patent Application Laid-Open No. 2002-153390) has a rehabilitation effect because the user grips the handrail of the bathtub with his / her own force, moves with his / her foot, and is a preferable handrail for the user. is there. However, the handrails required for bathtubs in Patent Document 3 (Japanese Patent Laid-Open No. 2002-153390) include the gripping force of the user and the tension force of the legs, and it is necessary to move to the standing and sitting position only by the handrail. Muscle strength is required for the abdominal muscles, thighs, and hips that raise and lower the waist, which is insufficient for people with weakness.
The manual stand-up lift of Patent Document 4 (Japanese Patent Application Laid-Open No. 2002-65766) can use the user's gripping force and leg tension force appropriately, and can have a rehabilitation effect. It does not operate and does not lead to independence support effects and improved living.
Even in elderly people and sick people with weak hands and legs, as long as they have their own strength, they want to perform a standing position such as bathing to stand on their own as in the past when they were healthy. In addition, there is always a desire for a self-supporting device with the ability of the user that can be achieved as much as possible. It is ideal to use a device that can be used not only in bathing but also in every life scene, and also requires a standing position assisting device that improves the self-supporting ability by the rehabilitation effect.

An object of the present invention is to provide an upright sitting position assisting device that can be used even for a person with weak leg-tensioning force, while also serving as a user's own rehabilitation during bathing. It is another object of the present invention to provide a device that assists standing and sitting before and after using the bedding and before and after using the toilet, and that is safe and independent on its own feet.
In general, elderly people often weaken their legs and feet more than the decline in grip strength, increasing the number of inconveniences such as falling and standing in the bathroom. However, there is resistance and shame in living with people, and if you can, you can stand alone on your feet and feel like you want to live independently, such as bathing and excretion by yourself. There are people who are difficult to become independent, including elderly people.
The present invention provides a gripping member for such people, as long as there is a force of the foot that supports his / her body weight even a little, while compensating for the weakness of his / her legs by grasping the gripping member in front of the user. When standing up, it is possible to shift from the standing state to the sitting position, and when standing, grasp the gripping member that is also in the foreground and move from the sitting state to the standing position as the gripping member rises forward and upward. This is a standing-sitting assistance device that can make a transitional movement while compensating for the weakness of its own legs. Those who have no problem with grip strength and lower back and legs use the gripping member as a handrail, and those who are very good at gripping the gripping member with both hands ask the caregiver to operate the handle part or do the switch operation of the drive part by themselves As the gripping member moves, you can stand up and sit safely and easily while stepping on your legs with your own power, so you can feel satisfied that you are standing and sitting with your feet at the same time. And rehabilitation of legs and legs. Also, if you are worried about grip strength, you can compensate for lack of muscular strength by adding measures such as holding a part of the body to the gripping member with a user holding tool, and also stand upright while sitting on your legs with your own power Since it can be performed, it becomes possible to use the muscles of the hands and legs and hips at the same time as rehabilitation when standing independently. Since the structure of the drive unit of the present invention is configured with a structure (self-locking mechanism) that does not cause a malfunction due to a user's load, there is no trouble such as reverse rotation due to the user's weight, and it can be used with confidence. It is possible to stop the gripping member at an arbitrary place.
The present invention has the following means for assisting such standing and sitting.

The standing position assisting device of the present invention adjusts the length between the support member connected to the drive unit and the gripping member, or adjusts the installation height of the device in the standing position assisting device, or interlocks with the drive unit. A guide that connects and moves the guide pole up and down with a guide that connects the support body, a member that the user grips, a support body that moves the member up and down in a straight or arcuate motion, and the like It has a drive part of a support body, and this drive part is constituted by the structure which does not move with the load concerning a grasping member, such as a user's weight, and when a user stands up from a sitting state, this member is moved to the front upper part from a user. Assists standing movement by moving.

In addition, when the user is sitting, the adjustment unit has a member to be gripped by the user, a support body that moves the member up and down by a movement such as a straight line or an arc shape, and a drive unit of the support body. Is configured so that it does not move with a load applied to the gripping member such as the weight of the user, and assists the sitting position movement by moving the member from the user to the lower front when the user is sitting from the standing state.

The drive unit cover of the drive unit is a joint part to be mounted on the side wall of the bathtub or the wall of the user's standing / sitting operation place such as a bathroom / toilet and the equipment of the user's standing / sitting operation place such as a bedding and a bed rail. Is provided and fixed at a necessary place, and the member gripped by the user is moved up and down by a preset movement such as a straight line or an arc shape to assist standing and sitting.

Further, the drive unit includes a rotating shaft of a gear to be engaged and a handle unit that rotates the rotating shaft, and a member that is held by a user at the tip of the rotating shaft by an appropriate operation of the handle unit is linear or arcuate. By moving up and down with a preset movement, the user shifts to a standing position and a sitting position.

In addition, the merging portion of the rotating shaft connected to the driving portion and the handle portion is constituted by a worm gear that converts the driving force at a ratio of 10 to 1 or more, so that the weight of the user can be reduced with a small operating force of the handle portion. The user is shifted to the standing position and the sitting position.

Accordingly, the standing position assisting device of the present invention adjusts the position of the gripping member gripped by the user, the drive unit that moves the gripping member, and the position from the drive unit or the device installation position to the gripping portion of the gripping member. By having the adjusting unit to be operated , the gripping member is driven and moved in an arc or a curve by a support body from one side of the user at the position of the linear or arc-shaped gripping member adjusted by the adjusting unit. This can assist the user in standing and sitting.
Specifically, if the movement path of the gripping member is a case where the user shifts from the sitting position to the standing state, the gripping member is moved from the user to the upper front, or the user shifts from the standing position to the sitting position. In this case, the gripping member can be moved in a preset motion such as a straight line or an arc shape, such as by moving the gripping member from the user to the front lower portion. The operation of the standing position movement and the sitting position movement can be assisted by the standing position assisting device of the present invention.

The standing-sitting assisting device of the present invention is an assisting device that enables the user to stand and sit with his / her foot even for a person with weak leg / tension force while also serving as a user's own rehabilitation. This device can be used in all places related to general living activities, such as taking a bath, waking up from bedding, standing up or sitting in a wheelchair or portable toilet, transferring from a bed, or toilet. It can assist human standing and sitting movements.
For example, when this apparatus is used at the time of bathing, it can be easily attached to and detached from a general household bathtub, is small in shape, and does not take up space. It does not require any major remodeling of the bathroom and can be easily installed, and its compact size has little effect on the cleaning of the bath, and it is difficult to get in the way of bathing by healthy family members. Since the gripping member of this device is located in front of the person taking a bath and there is a compact gripping member in the hollow above the water surface, if the gripping member is fixed in the hollow above the water surface at a convenient height for the user, When entering and exiting, the user can easily enter and exit as a handrail that can be positioned and is located in the hollow of the bathtub.
Devices for raising and lowering a user's body, such as a bathing assistance device having a seat of Patent Document 1 (Japanese Patent Laid-Open No. 2001-276164) and Patent Document 2 (Japanese Patent Laid-Open No. 10-192359), are those who are in a position to receive care. For this reason, there are many aspects that give the pride to leaving everything in bathing to other people and machines, and in general life can not feel the decline of physical strength and energy in the idea that you can not do anything by yourself, Even if people with weak leg strength are able to stand on their feet and sit in the bathtub, they can feel relaxed by reducing the negative feelings of leaving others to bathing hours that should be resting You can enjoy bathing.
When the user shifts to a standing position, the movement of the apparatus moves the user forward and upward, which is as if the caregiver is standing in front of the user and lifting the body. Conversely, when the user transitions to the sitting position, the gripping member assists the user to the lower part of the front with a movement close to the natural movement of lowering from the buttocks close to the center of gravity of the user's body. Both the sitting position does not put an unreasonable burden on the user's body. In addition, self-supporting with this device during bathing when muscles become flexible also serves as rehabilitation of the limbs, resulting in increased strength of the hands and legs, improved balance, and vitality and confidence in the overall life.
Speaking of assisting the user's standing / sitting position, which is operated manually by a caregiver, the device can stand / sitting with a force of, for example, 1/10 or less of the user's weight due to the gear structure. Since it can be assisted, the burden on the caregiver is low and the gripping member that the user grips gradually moves as the handle is turned by the caregiver's operation, and the gear self-locks no matter where the operation is stopped The mechanism works, and the gripping member does not move up and down or reversely rotate by the load on the gripping member such as the weight of the user.
For this reason, there is no sense of anxiety due to movement of the gripping member with the user's own weight, and even if the caregiver is forced to release the hand during the operation of the handle, the gripping member is arbitrarily It is safe in that it does not lead to accidents caused by movement. As a result, the caregiver operates the handle part with one hand while watching the user, and the auxiliary seat plate to be used for entering and exiting the bathtub with the other hand vacated by the caregiver during the movement. It is possible to prepare for sitting on the user by setting it on the upper buttocks, and bathing assistance is easy even if the caregiver is alone.
In the case of electric driving, a caregiver is not required and bathing is possible by the user's own operation.
In this way, driving operation is easy and anyone can handle it easily regardless of whether it has nursing qualifications or experience level, so bathing assistance, which is said to be the most burdensome in home care, will be easier. Therefore, increasing the possibility that family members help bathing will increase confidence and intimacy for both users and caregivers in the home.
Caregivers such as helpers visiting bathing assistance in the home need a lot of labor to wake up the user's body from the front of the user, and at least one leg must be put in the bathtub. Can't wake up standing in front of the user. Therefore, in many cases, the caregiver has a difficult posture such as bending his / her body diagonally from the outside of the bathtub, raising the user's body that has become wet and slippery, causing back pain and annoying the caregiver. ing. The present invention reduces caregivers' pain by facilitating bathing assistance, and allows the user himself to sit on his / her feet as well as normal bathing, so that the person who has become physically disabled and the strength It provides comfortable bathing time, confidence and vitality to the weak elderly.
Next, in the scene of waking up from bedding, it prevents people from struggling to wake their upper body from a supine state, or to slowly and stably lay their upper body, and to tilt or wobble and hit the head with a bed fence. For this purpose, the user can assist in waking up the upper body stably with a straight posture simply by grasping the gripping member of the apparatus. In addition, even if a person who wakes up in bed has something to support the body when waking up, such as grabbing a bed rail, there is almost no person who wakes up in Japanese futon to support them. This device can also assist a person who wakes up in a Japanese futon to wake up or stand and sit.
In general, the life of an elderly person who is close to bedridden may be in the range of action mainly based on bedclothes such as a bed or futon, a portable toilet, and a wheelchair, but it is necessary to transfer the toilet, wheelchair, and bed. There are many people who cannot stand or sit on their own unless they call a caregiver each time. When elderly people with weak legs or physically disabled people get up from the edge of a bed, chairs, wheelchairs, etc., they may not be able to stand up because their tension is not sufficient and their hips do not lift up. In many cases, it is possible to stand up smoothly if the body is raised by an external factor. This apparatus can stand up and sit on its own by moving the apparatus to a necessary place in such a living behavior scene or by fixing it to a necessary place. For caregivers, it is easy to change diapers or change trousers while the elderly are standing and grasping the device. Is reduced. In the space-saving action range, it is possible to reduce the burden on the user by eliminating the need to call a caregiver by grasping and moving the gripping member on which this device operates as a handrail, and the device can be used on its own. Assisting elderly people and bedridden activities by assisting waking up and standing in the range of these behaviors by driving them electrically or by helping caregivers improve their daily lives. It also leads to activation.
This device can be used even when the device is installed in the toilet or moved by a caster. However, in a space shared with other people who can live a healthy life, such as in the bathroom or toilet, the gripping member is fixed at a place that does not interfere with the end. Or by folding the support and fixing it like a handrail at the wall, and using the device by pulling out the gripping member only for those who need assistance, it can be shared with family and other people This can prevent the user from getting in the way and reduce the psychological burden such as the user's refusal and negative eyes.
In addition, since this device is small and has a simple structure, the device can be manufactured at low cost. Therefore, the device becomes a self-supporting nursing care product having a rehabilitation function that can be easily obtained by a person who wants to improve their life and independence.

For example, when the length of the handle portion is 150 mm and the length of the rotating support to the gripping member is 300 mm, the driving force for rotating the handle portion when 50 kg of the user's weight is applied to the gripping member It is explanatory drawing for calculating. In this case, the ratio of rotation of the worm (16) connected to the handle portion (2) and the worm wheel (15) connected to the support is 20 to 1, and when the handle portion (2) is rotated 20 times. The worm wheel (15) is configured to rotate once, and in order to rotate the support (6) by 90 degrees for the user to stand up or move to the sitting position, the handle portion is rotated five times. In this situation, the user's load of 50 kg applied to the support (6) is, when the number of teeth (number of teeth) is 1, the torque T in the worm wheel (15) is
T = 50Kg × 0.3m = 15kg ・ m The torque T1 of the worm (16) on the handle (2) side depends on the gear ratio.
T1 = 15 kg · m × 1/20 = 0.75 kg · m Thus, the torque W1 applied to the handle portion (2) is
W1 = 0.75 kg · m / 0.15 m = 5 kg In other words, when a 50 kg load is applied to the tip of the support (6), a torque of 15 kg is applied to the worm (16) 300 mm ahead. If the reduction ratio is 1/20, it is necessary to rotate the worm (16) 20 times in order to rotate the worm wheel (15) 360 degrees, but the torque applied to the worm wheel (15) is 0. The torque applied to the handle portion 150 mm ahead is 5 kg. Even in this same situation, the torque applied to the handle part can be reduced to 2.5 kg, which is half of the above, by reducing the reduction ratio of the worm gear to 1/40, or by using a number of gears, for example. It becomes possible. To give some examples, the user needs to rotate the support (6) 90 degrees for standing or sitting movement, i.e. the worm wheel (15) is rotated 1/4, so torque and handle operation are If the number of gears is 1/10 with a reduction ratio of 1/10, the torque is 10 kg and the number of gears is 2 gears with a reduction ratio of 1/4 × 1 (strip) of 2.5 revolutions 1/20. If the number of gears is 2 gears with a reduction ratio of 1/440 (2.5) at 1/4 x 2 (strip) and 1/40, the torque is 1.25 kg and 10 times at 1/4 × 2 (strip). Thus, depending on the combination of the gear reduction ratio and the number of strips, in the present invention, even if the user is a person with a weight of 100 kg, for example, the handle portion can be operated with a force of 1/10 to 1/20 of the weight. In reality, users can use their soles, knees, waist, etc. Since that example, the load applied to the support (6) is a part of the weight, the operating force of what number to increase turning the handle portion With such reduction ratio 1/50 of the gears can be further reduced. Therefore, if the rotation ratio in the gear portion is 10 to 1 or more, there is no problem in realizing the present invention. In addition, since the worm gear is self-locking and the worm cannot be rotated from the worm wheel, the support body does not rotate freely by the user's load unless the handle is operated, and complete reverse rotation is possible. When prevention is required, it is possible to achieve safety by incorporating a mechanical locking mechanism (not shown).

FIG. 10 is an explanatory view of a support expansion / contraction mechanism of the standing position assisting device of the present invention.
The position of the gripping member of the standing-sitting assistance device fixed to the bathtub varies depending on the user because the convenience position of the gripping member varies depending on the size, depth, body shape, height, etc. of the bathtub. Adjustment is required.
Therefore, by configuring the length between the support (6) and the gripping member (3) so as to be adjustable, a situation that is easy to handle for each user at each installation location is provided. Specifically, as shown in FIG. 10, the support (6) and the gripping member (3) are joined with a screw part (20) and fixed with a tightening nut (21), or a spring (not shown). The so-called ball plunger, in which the ball protrudes with the force of, is a notch type that fits into the groove, or tightening to fix two pipes by inserting a thinner pipe into a thick pipe and closing the diameter of the thick pipe Fix by length adjustment method such as a formula. As shown in FIG. 11, it is possible to adjust the installation position of the support body (6) easily for each user, and it is possible to adjust it freely. However, the gripping member (3) and the support body (6) described here are used. In the adjustment of the length between them, the arcuate radius of FIG. 13B described later is increased or decreased to improve the convenience of the user.

FIG. 11 is an explanatory view of the installation height adjustment of the bathroom specification in the standing position assisting device of the present invention.
When the drive part cover (1) is installed in such a manner that the bathtub side wall is sandwiched between the joints (31) and the stopper plate (7) is in contact with the upper side of the bathtub side wall, the drive part adjustment plate (32) is attached to the drive part. The position of the drive unit (23) can be adjusted to be higher or lower at the same time by making it possible to adjust the installation position such as raising or lowering the position fixed to the cover (1) with the height fixing screw (33). The height of the arcuate rotation center position, which is the root of (6), can be adjusted. This makes it easier for the gripping member (3) to grip the horizontal member minus 10 degrees to about 80 degrees in the vertical direction, rather than using 0 degrees in the horizontal direction and 90 degrees in the vertical direction for sitting and standing. When the auxiliary belt (12) shown in FIG. 4 or the auxiliary sheet (13) shown in FIG. 5 is used, it is easier to use the gripping member (3) in an arc shape at a higher position than the user. In addition, the range in which the gripping member (3) can be transferred is expanded by using it together with the support expansion / contraction mechanism, and the convenience of the user is achieved by various dimensions such as the size and depth of the bathtub, the body shape of the user, and the height of the user. It is.

FIG. 12 is a view for explaining the standing assisting action of the standing-sitting assisting device according to the present invention.
In general, for elderly people who have weak legs and legs, the body is lifted up from the sitting position by pushing the tub of the bathtub with the power of the hand or arm or by pulling the handrail in the bathroom. However, there are many situations in which the buttocks do not rise from the state like the user (11A) shown in FIG. This may not be possible to lift the body due to lack of strength in the hands and arms, but due to various factors such as weakness in the legs, pain in the knee joints, back pain, muscle stretching and balance, etc. It may not be possible to enter the standing state.
However, if the user's (11A) buttocks are lifted slightly as shown by the arrow (71) and rise to the height of the user's (11B) buttocks, the sole, ankle, calf, thigh, waist, etc. The muscular strength can be effectively used and balanced, and the subsequent operation becomes possible, and it becomes easy to shift to the standing state. If elderly people who have become unable to lift their body from the state of the user (11A) have only their energy, they will continue to make efforts to stand on their own, and their blood pressure will rise, and hot water will rise. It cannot be called, and it may lead to serious illnesses such as stroke and myocardial infarction and unexpected accidents. No matter how many times the same action is repeated by yourself, even if the person cannot move up to the standing position without exceeding his / her limitations, such as being unable to raise his / her buttocks or extending his / her legs, he / she can move forward. It is possible to shift to a standing state by adding a few external factors such as being pulled up, and if you increase muscle strength by using muscles of the body that you do not use on your own, or if you warm your muscles by bathing and you are in a flexible situation By moving the muscles, you can move muscles that were difficult to move in everyday life, the joints can be bent without pain, and people who can not stand in daily life can stand up with helping buoyancy when taking a bath, etc. I can expect. These are not only true for the elderly, but also for those who have been admitted to the hospital for a long period of time due to illness or injury, and whose muscle strength has been reduced.
Moreover, the auxiliary seat plate (24) shown in FIG. 12 (b) is set on the upper collar of the bathtub (10) before and after the user (11C) sits in the bathtub (10). Thus, the user (11C) who has weak legs can ease the bathing work by placing the buttocks on the auxiliary seat plate (24). Even when the user (11C) goes in and out of the bathtub (10) across the upper heel of the bathtub (10), the auxiliary seat plate (24) can lift the foot by not only the foot but also the buttocks seated. It is stable and easy to go, and you can get over the upper foot of the bathtub (10).
When using the standing position assisting device of the present invention, the caregiver can operate the handle portion with one hand to shift the user (11C) to the standing and sitting position, so the user (11C) can hold the back of the user (11C) with one free hand. Work such as supporting or wiping the body or setting the auxiliary seat plate (24) on the upper heel of the bathtub (10) while the user (11C) is standing up can be performed. Also, since the self-locking mechanism of the gear works and the load on the gripping member such as the weight of the user does not cause the gripping member to move up and down or reversely rotate, the user is in the middle of moving to the standing or sitting position. However, if it can be confirmed that the user is in a stable posture, the caregiver can release his hands from the handle and put both hands on the care, so bathing assistance can be performed alone.

FIG. 13 is an explanatory view of the movement of the support in the standing position assisting device of the present invention.
As shown in FIG. 13 (a), a movable support (28) is incorporated at the tip of the support (6) interlocked with the drive unit (23), and is moved up and down by a connecting guide pole (25). Is possible. The guide pole (25) moves along the guide rail (26) formed in the rail box (27), and the rotation of the support (6) connected to the drive unit (23) is controlled by the guide pole (25). By adding the movement of the movable support (28), the movement of the gripping member (3) can be converted into the trajectory of the guide rail (26). Therefore, the movement of the gripping member (3) is not limited to the arc shape, and it is possible to move to a preset straight line or curve.
As shown by the arrow (53) in FIG. 13 (b), the user can move up to the front and upward in an arc to enable standing, and the user can move to enable the sitting position by lowering to the front and lower in the arc. .
As shown by the arrow (54) in FIG. 13 (c), a movement that allows the user to stand straight up and forward from the user and linearly descends in front of the user to enable sitting. Can do.
As shown by the arrow (55) in FIG. 13 (d), a movement that allows the user to stand up in a curved line upward from the user and allows the user to sit down by curving in the lower part of the user. Can do.
Also, the rail box (27) shown in FIG. 13 (a) should be installed with a mounting attachment A (29) on the bathroom wall (30) such as the user's side or the front as shown in FIG. Thus, the standing position assisting device can be attached even if it does not straddle the side wall of the bathtub (10), and the rail box (27) is the drive unit cover described in FIG. 1 in the case where the drive unit (23) is incorporated. It also serves as (1). The attachment A (29) is thin and is first attached to the bathroom wall surface, and the rail box (27) is not shown in the attachment attachment A (29), but can be easily attached and detached by fitting. The installation that can be attached and detached means that the user can be removed when the standing-sitting assistance device becomes unnecessary because the user becomes healthy and can take a bath by himself without the need for bathing assistance. In addition, when the device is installed on the bathroom wall surface, it becomes an upright sitting assistance device in which the gripping member (3) shifts in the hollow of the bathtub, and the bathtub side wall is not used at the device installation location as shown in FIG. The user does not interfere with the movement of the foot over the upper heel of the bathtub.

FIG. 14 is a view showing an example of another installation method on the bathtub side wall of the standing position assisting device of the present invention.

It attaches between the drive part (23) and attachment attachment C (40) which were made, and the attachment attachment B (39) is being fixed to the side wall of the bathtub (10) with the tightening screw (8). These attachments are installed so that the side surface of the bathtub (10) is received by two to three surfaces, and as shown in FIG. 14, the support (6) and the gripping member (3) are integrated, and the drive unit (23) and It is also possible to receive and rotate at two places with the attachment attachment.

FIG. 15 is a view showing an example of another method for installing the standing-sitting assistance device of the present invention on the bathroom wall surface.
FIG. 13A shows the drive unit installed on the side surface of the user, but FIG. 15 shows that the attachment attachment D (41) is arranged on the bathroom wall surface (30) in front of the user (11). By installing the part (23), the standing-sitting position assisting device can be attached even if it does not straddle the side wall of the bathtub (10). The attachment attachment D (41) is thin and attached to the bathroom wall first, and the drive unit cover (1) is not shown in the attachment attachment D (41), but can be easily attached and detached by fitting. . The installation that can be attached / removed means that the apparatus can be easily removed when it becomes unnecessary as described in FIG. 13, and for example, the attachment attachment D (41) is attached to the bathroom wall surface of each house. If a caregiver, such as a helper who attends bathing assistance, carries the body position assisting device main body, it is possible to easily perform bathing assistance for a plurality of people with a single device.
The installation of the device on the bathroom wall surface (30) as described above hardly disturbs healthy persons, users, and caregivers, and basically the support (6), the gripping member (3), etc. Is a simplified shape, and when the legs are strong enough that the user does not need to operate the standing position assisting device, the gripping member (3) is fixed at a height that is easy for the user (11) to use. For those who do not need bathing assistance, it can be used as an easy-to-use handrail that exists in the hollow of the bathtub (10). It is very convenient that the handrail can be located at any position, and it can be used in combination with existing handrails, rather than handrails attached to bathtubs that are usually used for bathing and handrails fixed to the bathroom wall. By doing so, it is possible to create a situation where there are handrails on both sides of the user, so safety and convenience are also increased. When a healthy person takes a bath using the same bathtub, by fixing the gripping member (3) at an end position that does not get in the way without occupying a wide range in the bathroom and the bathtub by the standing position assisting device. In addition to being able to enjoy calm bathing without being a burden for healthy people, the shape is small and it does not take up space in the bathtub, so it is difficult to get in the way of cleaning the bathroom and bathtub.

As an embodiment for enabling self-operation of the present invention, FIG. 21 is an explanatory view when the user himself / herself operates the standing position assisting apparatus of the present invention, and FIG. 22 is a drive engine of the standing position assisting apparatus of the present invention. It is explanatory drawing using this.
21 and 22 show an embodiment in which the operation of the drive unit according to the present invention is not performed by a caregiver's handle, but the user himself / herself operates a drive engine by an electric motor. In FIG. 22, the gripping member (3) provided at the tip of the support (6) is provided with a forward rotation switch (36) and a reverse rotation switch (37) as a drive engine operation section, and a motor control section ( In 34) they can control the rotation of the motor (35). The rotational force of the motor (35) can move the support (6) in an arc through the reduction gear (38). An example of the movement of the forward rotation switch (36) and the reverse rotation switch (37) around the gripping member is shown in FIG. In FIG. 21, the user himself / herself operates the standing-sitting assistance device. For example, by rotating the right hand side of the grip (4) positioned at both ends of the gripping member (3) like an accelerator of a motorcycle. The switch (23) having a built-in motor (35) is operated by providing a switch with a structure in which a forward rotation switch is inserted and turning the right hand slightly in a specified direction. That is, as shown by the arrow (76) in the figure, the support (6) is rotated by rotating the grip (4), the gripping member (3) starts moving, and the movement is stopped when the grip (4) is returned. To do. Further, the reverse rotation switch (37) may be operated when the right hand grip (4) shown in FIG. 21 is rotated in the reverse direction, or may be operated by the movement of the left hand grip. Of course, the specifications of the motor control switch provided in each of the right hand and the left hand may be considered with emphasis on operability, and although not shown, by providing a button switch or the like near the grip (4) or the gripping member (3), The user himself / herself can also operate the standing-sitting assistance device. Moreover, although it is natural that the motor control unit (34) and the motor (35) are arranged as structures in the drive unit (23), they are not limited in product design. The reduction gear has been described as having a worm gear structure when the handle portion (2) is provided as shown in FIG. 1, but there is no problem with other gear structures. For example, a bevel gear is used. It is also possible to fulfill the purpose by crossing two axes. Although the electric motor has been described with reference to FIG. 22, although not shown in the figure, the support is operated by a transmission mechanism such as various types of energy that can be input from the outside, such as hydraulic control or water pressure control, as another driving method. Is also possible. In this case, the movement inside the drive unit is a movement peculiar to those control methods, but the movement of the support (6) accompanying the movement of the drive engine operation unit such as the forward rotation switch (36) and the reverse rotation switch (37) is The movement is the same in concept as the movement of the other embodiments, as shown in FIG. 13, and is an arcuate, straight, or curved movement. When the user is seated from the standing position, the support (3 ) Shifts downward in front of the user, and when the user stands up from the sitting position, the support (3) moves so as to shift upward in front of the user. The drive method using the drive engine here is a compact use that does not require a caregiver, as shown in FIGS. 13 and 15, when the device is attached to the bathroom wall surface and a manual operation such as a handle is not assumed. A situation is possible. In FIG. 22, it is described that the operation unit Bn outside the handle is further provided. This will be described in detail with reference to FIG.

FIG. 23 is a circuit block diagram for explaining the operation of the drive engine of the present invention in more detail. The upward direction switch SW1 and the downward direction switch SW2 provided on the support (6) and the speed of the operation speed are shown. The setting switch SW3 to be accelerated as the setting switch, the setting switch SW4 to be delayed, and the upper limit position confirmation SW5 and the lower limit switch SW6 of the support (6) to operate the motor control unit (34) to operate the motor (35 ). The upper limit position described here is the movement end position when the support (6) is raised to the highest position, and the lower limit position is the movement end position when the support (6) is lowered to the lowest position. It is. Here, SW1 and SW2 correspond to the forward rotation switch (36) and the reverse rotation switch (37) of FIG. These SW1 to SW4 can be operated not only from the operation part of the support (6) but also from the remote control. The operation part (B1) of the remote control (52) corresponds to SW1 to SW4 provided on the support (6). SW1 to SW4 are provided, and operations of SW1 to SW4 are transmitted from the remote control operation unit (B2) to the remote control reception unit (B3) wirelessly or by wire, and if SW1 in the remote control is turned on, the remote control reception unit L3 and L5 at ON
If SW2 in the remote control is turned ON, L4 and L5 at the remote control receiver are ON,
If SW3 in the remote control is turned ON, L1 and L5 at the remote control receiver are ON,
When SW4 in the remote control is turned on, L2 and L5 at the remote control receiving unit are turned on, so that the same operation as when the switch of the support (6) is operated can be performed by the remote control, and the remote control operation unit (B1) remote control transmission unit (B2) Since the structure of the remote control receiver (B3) is a well-known technique used in various electric products, description thereof is omitted here.
Further, this apparatus can enable motor control by voice in a voice reception control unit (B6) including a microphone (B4) voice input unit (B5) voice recognition unit and a voice command control unit.
For the sake of explanation, this apparatus uses five voice commands of “we”, “sita”, “mare”, “hayak”, and “okoku” as voice commands.
When the user utters words that become these voice commands to the microphone (B4), the voice is received through the microphone (B4) at the voice input unit (B5), and the support is received through the voice reception control unit ((B6)). The signal lines L1 to L5 of SW1 to SW4 provided in (6) are turned on corresponding to each of SW1 to SW4 in the same manner as the operation of the remote control receiving unit, provided that the voice command “Wa” “Sita” As for "," when voice command "Wa" is input, voice reception control is performed on L3 and L5 in order to turn on SW1 until a command other than "Wa" (generally "Tomare" command) is input. In addition, when the voice command “sita” is input, L4 and L5 are used to turn on SW2 until a command other than “sita” (generally “tomale” command). As will be described later, since it is inconvenient to keep moving in the direction of “we”, “mataha” and “shita” as described later, it responds to other commands correctly and is controlled. It is possible to move the support (6) in the same manner as operating the SW1 to SW4 provided on the support (6), since the recognition method from the input of this voice command is already well known in the art. Description is omitted.
FIG. 24 is a flowchart showing the operation of this apparatus, and the operation in the circuit block diagram of FIG. 23 will be described in more detail. In this apparatus, as indicated by SW3 and SW4, the moving speed of the support (6) can be changed by these switches. As shown in FIG. 24 (b), in this embodiment, the speed rank is set in five stages from 1 to 5, so that the speed is increased from 1 to 5 by operating SW3 or 5 to 1 by SW4. It is possible to reduce the speed. The motor control unit is illustrated in FIG. 24A, including the circuit block diagram of FIG. 23 including the five-stage speed variable in FIG. 24B. In step S1 of FIG. 24A, it is determined whether or not the remote control is valid. If the remote control is valid, the remote control input is confirmed in step S18. If there is any remote control input, the process returns to step S3, and if there is no remote control input, the process returns to S1. If the remote control is not valid in step S1, the voice input is confirmed in step S2, and if there is a voice input, it is checked in step 15 whether there is a voice command. Go to S3. If there is no voice input in step S2, the process goes to step S3. The presence / absence of remote control input and voice input can be determined by observing that any one of L1 to L4 in FIG. 23 is at the L5 level (switch is turned on). Next, in step S3, if L1 and L5 are ON from SW3 of FIG. 22 or SW of the operation unit (B1), the remote control reception unit, or the voice reception control unit, it is determined that there is a “fast” instruction. Then, it is determined whether or not the speed rank of (b) is currently 5. If the speed rank is 5, the process returns to S1, and if it is not 5, the speed rank is increased by 1 in step 20 and the process returns to S1. If L1 and L5 in FIG. 23 are OFF in step S3, the process proceeds to step S4. Then, in step S4, a “slow” instruction is issued if L2 and L5 are ON from either SW4 in FIG. 23, the switch of the operation unit (B1), the remote control reception unit, or the voice reception control unit (B6). In step S16, it is determined whether the speed rank in (b) is currently 1. If the speed is 1, the process returns to S1. If not, the speed rank is decreased by 1 in step 17 and the process returns to S1. . If L2 and L5 in FIG. 23 are OFF in step 4, the process proceeds to step S5.
In step 5, either “SW1” in FIG. 23, the switch of the operation unit (B1), the remote control reception unit, or the voice reception control unit (B6) instructs “Up” if L3 and L5 are ON. If there is, enter S11, and if it is OFF, proceed to Step S6.
In step S6, if L4 and L5 are ON from either SW2 in FIG. 23, the switch of the operation unit (B1), the remote control reception unit or the voice reception control unit (B6), an instruction “down” is issued. If there is, enter S7 and if it is OFF, return to step S1.
