Abstract

PROBLEM TO BE SOLVED: To provide a chair and up-down stepper combination that is, in spite of compactness, capable of improving muscular strength of an aged person and performing effective rehabilitation for a hemiplegic person.SOLUTION: A chair having a prescribed sitting height is designed to have a plurality of steps divided in the sitting height direction (height direction), with divided steps placed successively on the lowermost step which is the lowest divided step, so that the steps of a plurality of heights including the lowest divided step are created. This structure is for obtaining a needed height by setting upright all upper steps toward the backrest of the chair except the lowest step and then successively leaning forward the upper steps over the lowest divided step until it forms the needed height including the lowest divided step. Meantime, the upper surface of each step is provided with a seat surface and, on the upper surface of the highest step, there is installed in addition to the seat surface a fence for preventing slipping down from the chair.

Description

  The present invention relates to a chair that is often used for exercise, and in particular for exercise aimed at maintaining and improving the muscular strength of the elderly, after falling down due to cerebrovascular disorders such as cerebral infarction, cerebral thrombus, subarachnoid hemorrhage, etc. When using hemiplegic symptomatic patients with hemiplegic symptoms, ascending / descending with multiple steps or using other exercises or other rehabilitation equipment so that effective rehabilitation (function recovery training) can be performed. Various chairs are used as auxiliary chairs.

When a cerebrovascular disorder develops, the patient is admitted to a hospital and undergoes surgical treatment (surgery) or medical treatment using drugs.
Even if such surgical treatment and medical treatment are performed and the patient escapes from an acute symptom state in which soft tissues such as muscles and ligaments have been damaged, the functional tissue in the brain engaged in physical exercise is damaged. It is often seen. When such damage to the functional tissue in the brain occurs, paralysis occurs on one of the left and right sides (one side) of the body, resulting in a state in which half of the body cannot be moved, that is, hemiplegia (half body incompetence).
In this case, the part where hemiplegia occurs, the degree of hemiplegia, etc. vary depending on the position and degree of damage occurring in the brain, and the degree of hemiplegia and the type of disability vary greatly among individuals.

When hemiplegia occurs as a sequelae of cerebrovascular disorders, rehabilitation is performed to relieve hemiplegia and restore physical function to return to the home or work.
In the case of cerebrovascular disorder, how effective rehabilitation of the optimum type is performed according to each period in the acute phase (within about 1 month from the onset) and recovery phase (about 1 month to 1 year after the onset). Is said to be important in functional recovery.

In the past, it was thought that hemiplegia would not recover after treatment because hemiplegia would not regenerate destroyed brain neurons. For this reason, rehabilitation of persons with hemiplegic symptoms has been aimed at training the lower limbs and upper limbs on the side without paralysis so that they can walk and live daily.
However, recent advances in brain science have revealed that even if a part of the brain is damaged, other parts that have escaped damage have the ability to substitute for the role of the damaged part, i.e., plasticity. Rehabilitation treatment aimed at overcoming has also been performed.

  For this reason, in rehabilitation, not only can the side without paralysis be trained to enable walking and daily life, but also the side with paralysis can be moved with the assistance of others to move from the arm or leg on the paralysis side to the brain. On the other hand, it is necessary to promote the plasticization of the nervous system (acquisition of cranial nerve substitute ability, nerve regeneration, reorganization) by sending a stimulus.

When plasticizing the nervous system, in addition to moving the paralyzed arm and leg by a caregiver, etc., the paralyzed person imagines moving the paralyzed arm and leg and moves the body from the brain side. It is said that it is effective to image the movement information command to the side.
In other words, moving the body from the paralyzed side toward the paralyzed side in synchronization with sending a stimulus (motor information command) from the paralyzed side to the brain by forcibly moving the paralyzed arm or leg It is said that the function recovery can be effectively performed by promoting plasticization by interlocking the motion information commands from both directions, which is to imagine that the motion information commands to be commanded are sent.

For this reason, rehabilitation is actively carried out after getting out of the state of acute symptoms.
Rehabilitation in the acute phase (within about 1 month from the onset) is centered on "physiotherapy", and rehabilitation in the recovery phase (about 1 month to 1 year after the onset) further adds "occupational therapy".

  Physical therapy is a therapy designed to improve basic physical ability by performing exercise therapy or manual treatment for the purpose of improving the basic movement ability when a physical function is impaired. This physical therapy begins with slowly turning over or moving the body with the assistance of a physical therapist, following the instructions of a doctor.

Occupational therapy is a so-called therapy that improves applied movement ability, and begins with training to sit on a bed or hold an object. This prevents the limb joint from contracting.
As recovery progresses further, it aims to acquire and improve daily activities such as changing clothes (changing clothes) and adjusting (appearance and shape), walking training, and eating, toilets, bathing, and washing. Performing exercise training. Such occupational therapy is initially started at the bedside, and then exercise training is performed in actual situations.

When the recovery phase of rehabilitation is complete and functional recovery is achieved to some extent, the patient is discharged from the hospital.
Even after discharge, it is necessary to go to a hospital or rehabilitation facility regularly to perform rehabilitation, and function recovery training is continuously performed according to the menus instructed by doctors and physical therapists. In addition, hemiplegic patients themselves are instructed to move their bodies voluntarily and eagerly.
For this reason, it is important to perform rehabilitation at home, and strong motivation and self-training are required to overcome hemiplegia.

In hospitals and rehabilitation facilities, various rehabilitation devices are provided, rehabilitation using these rehabilitation devices is performed, and home rehabilitation devices are also being developed.
Examples of rehabilitation equipment include walking training parallel bars in which a pair of straight parallel bars are supported horizontally in the shape of a handrail by a support, or a string on a pulley and gripping both ends of the string with left and right hands. Various types of devices have been developed, such as an upper limb vertical exercise trainer that pulls down, an upper limb rotation exercise trainer that grips and rotates a pedal-like object of a bicycle with left and right hands, an elevating staircase, and a stepping exercise device.

  However, there are many rehabilitation devices with muscle training, and even those with hemiplegic symptoms, one side is healthy but one side is configured for healthy people There are few, and most of them are motorized for both paralysis and elderly people, and both left and right can be trained. It was difficult to continue rehabilitation using a rehabilitation device such as a hospital in general households because there were many things and there were few voluntary uses, so the plasticizing effect was small.

  As mentioned above, rehabilitation is performed in hospitals, rehabilitation facilities, and homes. However, according to the stories of those who have actually suffered from cerebral infarction, hemiplegia as a sequelae, and who have been fighting illness and rehabilitation, the current rehabilitation Then, it was found that there are various problems.

For example, at the time of admission, hemiplegic patients are waiting for most of the time resting on the bed, despite the enthusiasm and willingness to rehabilitate, and the time for rehabilitation is short, The frequency is low.
It is impossible to rehabilitate a person with hemiplegic symptom who has difficulty in limbs on one side of the body because it is dangerous because it is dangerous, so it is safe and effective training guidance and assistance are provided This is because a physical therapist and a caregiver must be accompanied by training. In addition, the number of rehabilitation facilities and the number of rehabilitation equipment are limited, and the number of physical therapists and caregivers is also limited, so that many people with hemiplegia cannot fully rehabilitate. There are also circumstances.

  On the other hand, after discharge, it is necessary to perform rehabilitation at home. For this reason, there are various types of rehabilitation equipment for home use, but they are complex and large-scale, and they have few functions to be recovered and are expensive, so they are inconvenient to use at home and have effective function recovery. It was not enough to train.

In particular, many chairs currently in use have only the function of a chair, and another table must be used for rehabilitation using a table. Therefore, preparing two types of chairs and raising / lowering bases is often unsuitable for home use in terms of space and cost. Furthermore, the chair itself often requires special items depending on the application, and from the actual experience of the person who became hemiplegic, the current rehabilitation equipment is the physical It does not take full account of mental conditions and requests.

For example, in the “wooden seat height variable chair” shown in Patent Document 1 (utility model registration No. 3087980), as shown in FIG. 4, the height setting of the seat height variable chair A is set at the lower end of each leg of the chair. 5 and 6 are added. In this case, it is necessary to connect the leg to the four legs of the chair by screwing with bolts and nuts, but the weak leg such as the elderly and the hemiplegic symptom are two parts. The work of adding 6 or removing it is extremely laborious and dangerous for the handicapped.
Furthermore, in Patent Document 1, there is a footrest B just before the chair, and the rear edge side of the footrest plate 12 is hooked on the connecting member 3 straddling between the front legs of the chair A by a hook member 13 so as to be freely disengaged. However, there is a pair of left and right pedestals 11 on the front edge side of the footrest plate 12, and the height of the pedestal 11 is also adjusted by the connecting legs 5 and 6 according to the height of the legs of the chair. There is a need.

Further, in Patent Document 2 (Japanese Patent Laid-Open No. 7-8350) “Deformable Chair”, the hydraulic cylinder is connected to the push side and the pull side (the switching valve is opened) or closed (the switching valve is closed). The pressure cylinder is made fluid and fixed to control the mechanical device. As a result, chair height, back and forth movement, backrest bending movement, wide movement of both thighs and sides, front and back and up and down movement, pillow back and forth and up and down movement, etc. can be done with simple operation of the pump lever Become.
However, it is necessary to be expensive, and it is difficult to permanently install at home.

As described above, in elderly persons and hemiplegic patients who are subjects of the present invention, adjustment of the chair height as in Patent Document 1 may take time or may be dangerous, Needless to say, in Japanese Patent Application Laid-Open No. 2004-228688, automation is so advanced that rehabilitation aimed at brain plasticity expected from spontaneous movement cannot be performed at all.

The exercise chair of the present invention that solves the above problems is
In a chair having a predetermined seating height, it is divided into a plurality of stages in the seating height direction, and by placing the divided stages on the lowermost divided stage in sequence, the height of the lowest divided stage (hereinafter referred to as the lowest stage) is set. It is characterized by creating multiple kinds of steps including the height.
Each stage including the lowermost stage of the exercise chair of the present invention is characterized in that a seating surface is provided on the upper surface side.

Further, the backrest side of the chairs of the other steps except for the lowermost step of the exercise chair of the present invention is characterized in that it can be rotated in the front-rear direction of the chair by a horizontal axis provided respectively.
2. The exercise chair according to claim 1, wherein a stopper is provided on at least one of the left and right side surfaces of the divided stage of the exercise chair according to the present invention.
In addition, a slip prevention fence is provided on the top surface of the divided stage of the exercise chair of the present invention.

The inventor of the present invention has previously proposed a plurality of support rods, and a continuous handrail rod that is connected to the top of the plurality of support rods and is supported horizontally by a looped handrail rod. The rehabilitation apparatus of the present invention and the exercise chair of the present invention are provided, and the exercise chair of the present invention is provided on the inside of the handrail. The rehabilitation movement by the exercise chair or as an auxiliary chair for other rehabilitation exercises It is the compound rehabilitation equipment characterized by being arranged.
The loop handrail bar of the rehabilitation device for continuous walking has at least one opening / closing means.

  The feature of the exercise chair of the present invention is that it is effective particularly for exercise aiming to maintain and improve muscle strength of the elderly, as well as for those with hemiplegia who have left behind the hemiplegia after falling down due to cerebrovascular disorder It is invented as a chair that is used as an auxiliary when using different types of steps or other movements or other rehabilitation equipment so that it can perform rehabilitation (function recovery training).

That is, the present invention is a chair / lift platform that can be applied to maintenance and improvement of muscle strength of elderly people and rehabilitation of hemiplegic patients. Accordingly, the type of exercise that can be applied is the raising and lowering movement of the table, but the height of the table is not constant depending on the degree of muscle strength, paralysis, or the form of application. Therefore, by dividing the seat height as a chair into a plurality of stages and placing the upper divided stage sequentially at the lowest stage, it is possible to create something close to the required height.

Moreover, since the lifting and lowering movement can be instructed using one's intention and one's own hands and feet, it is highly spontaneous and can be expected to be more effective in promoting brain plasticity. In addition, since the size of the device is moderately small, and the present invention can be combined with a rehabilitation device for continuous walking composed of a looped handrail that is a patented patent of the present inventor, the present invention can be combined. Occupied area can be reduced. As described above, the aforementioned plasticity of the brain is further promoted, and since the rehabilitation function is combined, it can be applied in a small space, so that it can be used at home.

By using the present invention in the vicinity of the inside and outside of the rehabilitation equipment for continuous walking, it is possible to exercise while holding the loop-shaped handrail bar to prevent falling.
In addition, since a slip prevention fence is installed on the top surface of the split stage (the seat surface as a chair), it is popular among those with hemiplegia who have a lot of slippage during exercise, and that are difficult to perceive even when slipping. is there.

At the same time, here, the seat height value h4 is divided into, for example, four levels in the height direction, and the lowest level 20 (hereinafter the lowest level). The first stage, the second stage, and the third stage (hereinafter referred to as the uppermost stage) overlap each other to realize a predetermined seat height h4.
Here, in order to make it easy to assemble the first to third divided stages sequentially, fulcrum rods 31 to 33 penetrating the chair are provided in the vicinity of the right end of each stage, and each stage has this fulcrum. The rod rotates around the rod.

Referring to FIG. 2 in detail, when the uppermost stage 23 is first rotated clockwise around the fulcrum rod 33, the uppermost stage 23 has at least one of the stoppers 25, 26 provided in the width direction around the backrest 27. Stop by hitting the side plate 28.
Thereafter, the second stage and the first stage similarly rotate around the fulcrum rod 32 and the fulcrum rod 31 respectively, the second stage hits the third stage (the uppermost stage), and the first stage hits the second stage and stops.
This is the state shown in FIG. 2 (a). At this time, the lowermost stage 20 is a table having a height h1 (hereinafter referred to as a table height). .

Next, when the first stage 21 is rotated counterclockwise around the fulcrum rod 31 in the state of FIG. 2A, the state of FIG. 2B is obtained, and the height of the first stage 21 is added to the lowermost stage 20 of h2. High height can be realized.
Similarly, when the second stage 22 is rotated counterclockwise around the fulcrum rod 32 in the state of FIG. 2B, the state of FIG. 2C is obtained, and the height of the first stage 21 and the second stage 22 is set at the lowermost stage 20. The height h3 with the added can be realized.
Further, in the state of FIG. 2C, when the third stage 23 is rotated counterclockwise around the fulcrum rod 33, the height of the third stage 23 is added to the lowermost stage 20, the first stage 21, and the second stage 22. As a result, the height h4 shown in FIG. 1C can be realized.

By using the difference in height between h1 and h4 as described above, it is possible to provide an auxiliary chair for handling lifting and other equipment.
In addition, since the heights of h1 to h4 may be used depending on the type of exercise and the purpose, the seating surface that can be seated or stepped on on the upper surface of each step including the lowest step. It is preferable to have
