Description

{Right and left variable rotation pedal type exercise equipment for remedical exercise}

The present invention relates to a left-right variable rotation pedal-type exercise device for rehabilitation exercise, and more specifically, to a left-right variable rotation pedal-type exercise device for rehabilitation exercise, in which, when performing a pedaling exercise like pedaling a bicycle, the rotation axis of the pedal operates forward/backward and the pedal rotation range provides a separate rotation range for each left-right movement range of a body joint, thereby enabling rehabilitation exercise to be performed safely and efficiently.

One of the most important abilities for humans is the ability to walk and move. However, if a person's muscles are built up due to stiffness or if they do not walk or exercise sufficiently for a long period of time, not only will their joints become hardened and they will completely lose their ability to move, but the muscles throughout their body will also contract and deteriorate. Therefore, in order to prevent this, they must perform continuous and repetitive joint movements.

Aerobic exercise, including walking, is suitable for health and rehabilitation for almost everyone, including people with paralysis or physical disabilities, elderly people with reduced activity, diabetics, and people at risk of myocardial infarction. However, it may be difficult to do aerobic exercise outdoors due to time, location, and physical limitations.

The problem for people with musculoskeletal disorders is that if they have sarcopenia, their muscles become thinner and denser, and their strength decreases, making daily life (maintaining posture, exercising, etc.) difficult.

Patients with musculoskeletal disorders have stiff muscles and joints due to problems in the muscles and nervous system, which makes their movements unnatural and causes large differences in the range of movement of left, right, front, and back joints and in strength.

On the other hand, there may be problems with sitting posture for people with physical disabilities, and there may be problems with spinal diseases caused by posture in obese people and the elderly.

People with back pain tend to bend their necks and backs more than the average person, which puts more strain on their spine and causes tension in their neck and back muscles, which leads to more pain and discomfort.

For the elderly who are severely obese and have weak legs and a hunched back, using a regular standing/seated bicycle increases the burden on the cervical and lumbar (neck, lower back) discs.

When you consider your riding posture, you are in a position where your back is bent and your lower back muscles are stressed.

Standing/seated bikes cause a hunched back and forward neck posture.

Maintaining this posture for a long time puts a lot of stress on the neck and back, which can lead to back pain and stiff neck muscles.

Meanwhile, considering the difference in body weight between the general public, the obese, and the elderly, the obese and the elderly with back pain experience a situation where the pressure on their backs is greatly increased when sitting.

Problems with existing bicycles for rehabilitation include that it takes a long time to set up before exercise can begin, and the body tilt cannot be maintained when using them. In severe cases, a rehabilitation patient may fall over along with the bicycle, which can lead to safety accidents.

The problem with using traditional bicycles for people with physical disabilities is that they lack safety and convenience when used.

Safety issues include the risk of falling when riding or using the bicycle, and socially disabled people who use wheelchairs or walking aids have difficulty standing on both feet, making it difficult to ride existing bicycles without an assistant, as they must support themselves with one foot.

People whose joints are stiff and cannot straighten their knee joints have a problem where their left and right leg movements are different, causing their body to tilt due to a loss of left and right balance every time they turn the pedal.

This requires the protection of assistants, raises safety issues and requires assistants to be on standby at all times. It is also disadvantageous in terms of convenience and causes inconvenience in terms of posture.

Sitting on a bike can cause spinal curvature problems, which can lead to problems with the muscles of the neck, back, and waist.

In other words, the cylinder rod of the pivoting cylinder (170) is connected to the seat (130) support side bracket extended toward the lower end of the front end of the rear seat support frame (142) via a front hinge, and the base end of the pivoting cylinder (170) is connected to a pair of lower base bars (112) forming the base (110) via a hinge, so that the cylinder rod of the pivoting cylinder (170) is connected to the rear frame (140) supporting the seat (130) and backrest (150) via a front hinge, and the base end is connected to the base (110) via a base (110) hinge.

The rear backrest frame (146) is provided with a backrest (150) to support the back of a rehabilitation patient from behind, and side guides (156) are further provided on the rear backrest frame (146) to be positioned on both left and right sides of the backrest (150). The rear backrest frame (146) is provided with a pair of left and right side guides (156). The left and right pair of side guides (156) support the upper body of the rehabilitation patient more stably from both left and right sides, thereby helping to perform lower body rehabilitation exercises or arm rehabilitation exercises of the rehabilitation patient more stably.

When the cylinder rod of the above-described rotational operating cylinder (170) is moved forward, the rear rotational operating frame (144) is rotated to a position that is relatively higher up toward the front, the rear seat support frame (142) is also rotated to a position that is relatively higher up, the seat (130) is raised to be arranged in a horizontal direction, and the backrest (150) is in an upright state.

In this state, the rehabilitation patient places his/her buttocks on the seat (130) and the backrest (150) supports the rehabilitation patient's back from behind, that is, while sitting, the rehabilitation patient holds a pair of pedals (166) on the left and right with both hands and turns the pair of pedals (166) on the left and right like turning bicycle pedals (166), thereby allowing the rehabilitation patient to perform arm exercises.

Meanwhile, in a state where the cylinder rod of the above-described rotational operation cylinder (170) is moved backward, the rear rotational operation frame (144) is tilted backward so as to be relatively laid back, the rear seat support frame (142) is also tilted backward so as to be relatively laid back, the seat (130) is tilted backward so as to be inclined backward, and the rear backrest frame (146), the backrest (150), and the left and right side guides (156) are also tilted backward so as to be laid back at a certain angle, and the rehabilitation patient places his or her buttocks on the seat (130) so that the seat (130) supports the buttocks of the rehabilitation patient from below, and at the same time, the backrest (150) supports the back of the rehabilitation patient from below, in other words, in a state where the rehabilitation patient lies down and places both his or her left and right feet on the pedals (166), the rehabilitation patient turns a pair of pedals (166) on the left and right with both legs and feet like turning a bicycle pedal (166), thereby allowing the rehabilitation patient to exercise the lower body, especially the leg parts. It becomes possible to implement it.

As described above, the present invention can be configured such that when a rehabilitation patient performs an exercise of rotating a pair of pedals (166) and the pedaling connection links (166RL) with both feet, the crank body (164) rotates and at the same time, a pair of pedals (166) coupled to the crank support box (162), the crank body (164), and the pair of pedaling connection links (166RL) slide forward and backward along the moving slot of the base-side pedaling frame (118). That is, the lower part of the crank support box (162) is slidably supported on the base-side pedaling frame (118) of the base (110), and the crank support box (162), the crank body (164), and the pair of pedals (166) are slidably coupled to the base-side pedaling frame (118).

Therefore, according to the present invention, when a rehabilitation patient performs an exercise of rotating a pair of pedals (166) and the pedaling connection link (166RL) by placing both feet on a pair of left and right pedals (166) as if stepping on a bicycle pedal (166), the crank body (164) rotates and at the same time, a pair of pedals (166) connected to the crank support box (162) and the crank body (164) and the pair of pedaling connection links (166RL) slide forward and backward along the moving slot of the base-side pedaling frame (118), which is a main part of the base (110), thereby enabling the rehabilitation patient to perform leg rehabilitation exercise or waist rehabilitation exercise, which is a lower body part, by the forward and backward movement while turning the pair of pedals (166).

At this time, as described above, while the rehabilitation patient is sitting on the seat (130), and the backrest (150) supported by the base (110) is raised so that the rehabilitation patient's back is supported from behind by the backrest (150), a rehabilitation exercise of the arm portion may be performed in which the rehabilitation patient holds a pair of pedals (166) with both hands and turns a pair of pedals (166) like turning a bicycle pedal (166), or while the rehabilitation patient rests his/her buttocks on the seat (130), and the backrest (150) supported by the base (110) is laid back by the rotational operating support, so that the back of the rehabilitation patient is supported from below by the backrest (150), in other words, while the rehabilitation patient is lying down, the rehabilitation patient attaches his/her feet to a pair of pedals (166) and turns a pair of pedals (166) like turning a bicycle pedal (166).

Therefore, the left-right variable rotation pedal-type exercise machine for rehabilitation exercise of the present invention has the effect of enabling even rehabilitation patients with physical diseases such as hip joints to perform rehabilitation exercise in a balanced manner because, when a rehabilitation patient places his or her feet on both pedals (166) and pedals as if pedaling a bicycle, both pedals (166) rotate and move forward and backward based on the crank support box (162). Meanwhile, as described above, when a rehabilitation patient sits, holds a pair of pedals (166) with both hands and turns them as if turning a bicycle pedal, the left-right variable rotation pedal-type exercise machine for rehabilitation exercise of the present invention has the effect of enabling a rehabilitation patient to perform arm rehabilitation exercise safely and efficiently because, based on the crank support box (162), both pedals (166) rotate and move forward and backward based on the crank support box (162). In the present invention, since the pedal (166) can be rotated relative to the base (110), which is a stable structure at the bottom, and can be operated forward and backward at the same time, even rehabilitation patients with physical diseases such as hip joints can perform rehabilitation exercises for the lower body, especially the legs, in a balanced manner, and, if necessary, can perform rehabilitation exercises for the arms in a sitting position, which is more meaningful.

In other words, the left-right variable rotation pedal-type exercise device for rehabilitation exercise of the present invention has the effect of enabling balanced rehabilitation exercise even for patients with physical diseases such as hip joint disease, since when a rehabilitation patient pedals like pedaling a bicycle by placing their feet on both pedals (166) and the pedals (166) move forward and backward based on the crank support box (162).

For example, when a rehabilitation patient with a hip joint in one leg performs a pedaling exercise by placing both feet on the left and right pedals (166) and stepping on both pedals (166), if both pedals (166) do not move back and forth but remain stationary, it is difficult to perform a rehabilitation exercise of the leg part with the hip joint. However, in the present invention, when a pedaling exercise is performed by stepping on both left and right pedals (166), both left and right pedals (166) rotate like bicycle pedals (166) and simultaneously move back and forth on the crank support box (162). Therefore, even if the patient has a physical disease such as a hip joint and is undergoing rehabilitation, there is an effect of being able to perform a rehabilitation exercise in a balanced manner.

In addition, since the present invention allows a rehabilitation patient to perform rehabilitation exercises while sitting or lying down stably, it also has the effect of preventing serious safety accidents, such as a rehabilitation patient falling and sustaining an injury while performing rehabilitation exercises.

The present invention enables rehabilitation exercise of the lower body like a lying-down bicycle that performs a pedaling function by having a rehabilitation patient lie down and turn a pair of pedals (166). While a conventional standing bicycle does not have a backrest (150), a backrest (150) is provided. When comparing the pressure in the lower back, when performing rehabilitation exercise while lying down like in the present invention, the pressure is 0.75 bar when the lying angle is 45 degrees, whereas the pressure in the conventional standing bicycle is 1.5 bar and in the conventional sitting bicycle is 1 bar. Therefore, it can be seen that when performing rehabilitation exercise while lying down like in the present invention, the pressure in the lower back is reduced, so that rehabilitation exercise of the legs and lower back can be performed without strain.

In addition, the present invention has a neck support function in a lying position. In a lying position, the upper front part of the backrest (150) functions as a neck support to support the head and neck of the rehabilitation patient from behind. Existing standing bicycles and sitting bicycles do not have a neck support function.

According to the present invention, when performing rehabilitation exercise in a lying position, the weight of the neck is significantly reduced compared to that of a conventional upright bicycle and a recumbent bicycle. When the weight of the neck is 5 kg, when performing rehabilitation exercise in a lying position according to the present invention, the weight of the neck is approximately 2 to 3 kg, whereas the weight of the neck of a conventional upright bicycle is approximately 12.2 kg and the weight of the neck of a conventional recumbent bicycle is 8 to 10 kg. Therefore, when performing rehabilitation exercise in a lying position according to the present invention, the weight of the neck is significantly reduced, thereby preventing a rehabilitation patient from having the effect of the rehabilitation exercise reduced due to excessive load applied to the neck during the rehabilitation exercise.

Meanwhile, as described above, a pair of upright posts (115EP) are provided on the inside of the upright base frame (115), and the front connection reinforcing bar (116) is slidably connected to the pair of upright posts (115EP) on the left and right so as to be able to slide in the upright direction, and the lower surface of the front connection reinforcing bar (116) and the upper surface of the front cross bar (113) are configured so that the upper and lower ends of a pair of left and right base-side springs (115SP) connected to the outer peripheral surfaces of the pair of upright posts (115EP) on the left and right are in contact, and the base (110) may further include a lifting operation unit connected between the lower surface of the base-side pedaling frame (118) and the lower base bar (112), and the lifting operation unit may be configured as a lifting operation cylinder (122) in which a vertical cylinder rod is connected to the lower surface of the base-side pedaling frame (118) and the lower end is connected to the lower base bar (112).

When the cylinder rod of the elevating operation cylinder (122) is raised, the front connection reinforcing bar (116) and the base-side pedaling frame (118) are raised, so that the height of the crank support box (162) and the left and right pair of pedals (166) can be relatively increased, and the left and right pair of base-side springs (115SP) are stretched so that the base-side pedaling frame (118), the crank support box (162) and the left and right pair of pedals (166) can be stably supported by elastic force, and when the cylinder rod of the elevating operation cylinder (122) is lowered, the front connection reinforcing bar (116) and the base-side pedaling frame (118) are lowered, so that the height of the crank support box (162) and the left and right pair of pedals (166) can be relatively decreased, and the left and right pair of base-side springs (115SP) are compressed so that the base-side pedaling frame (118) and the crank support It is possible to stably support the box (162) and a pair of left and right pedals (166).

Accordingly, the present invention can freely adjust the height of a pair of pedals (166) in response to the physical condition of the rehabilitation patient, such as the height of the rehabilitation patient, so that it can be expected to have a more helpful effect in the rehabilitation exercise of the rehabilitation patient.

Meanwhile, in the present invention, the base-side pedaling frame (118) of the base (110) is configured in a box shape with a hollow portion therein, a spring coupling shaft (118SCS) is built into the interior of the Bates-side pedaling frame, a first guide spring (118FGS) and a second guide spring (118SGS) are coupled to the outer surface of the spring coupling shaft (118SCS), and the lower portion of the crank support box (162) is coupled to be able to move forward and backward along the spring coupling shaft (118SCS) via a connecting bracket (118CB). The inner ends of the first guide spring (118FGS) and the second guide spring (118SGS) are in contact with both ends of the connecting bracket (118CB).

Accordingly, the present invention is such that when a rehabilitation patient pedals like pedaling a bicycle by placing his or her feet on both left and right pedals (166), the crank support box (162), the connection bracket (118CB), and both pedals (166) are moved forward and backward together on the base-side pedaling frame (118). When the crank support box (162), the connection bracket (118CB), and both pedals (166) move forward on the base-side pedaling frame (118), the first guide spring (118FGS) is stretched and the second guide spring (118SGS) is compressed. When the crank support box (162), the connection bracket (118CB), and both pedals (166) move backward on the base-side pedaling frame (118), the first guide spring (118FGS) is compressed and the second guide spring (118SGS) is stretched, thereby maintaining the rehabilitation exercise intensity for the lower body of the rehabilitation patient with appropriate elasticity. Therefore, it has the effect of enabling rehabilitation patients to perform rehabilitation exercises of appropriate intensity on their lower body parts.

In addition, when the rehabilitation patient holds a pair of pedals (166) with both hands while sitting and turns them as if turning bicycle pedals (166), the crank support box (162), the connecting bracket (118CB), and both pedals (166) move forward and backward in the base-side pedaling frame (118), and when the crank support box (162), the connecting bracket (118CB), and both pedals (166) move forward in the base-side pedaling frame (118), the first guide spring (118FGS) is stretched and the second guide spring (118SGS) is compressed, and when the crank support box (162), the connecting bracket (118CB), and both pedals (166) move backward in the base-side pedaling frame (118), the first guide spring (118FGS) is compressed and the second guide spring (118SGS) is stretched, so that the rehabilitation exercise intensity for the upper body part of the rehabilitation patient, especially the arm part, is also appropriate. Since it can be maintained with elasticity, it also has the effect of enabling rehabilitation patients to perform rehabilitation exercises of appropriate intensity on their upper body.

Since the compression and extension functions of the first guide spring (118FGS) and the second guide spring (118SGS) enable rehabilitation exercise with appropriate elastic strength for the lower body or upper body of the rehabilitation patient when the base-side pedaling frame (118) of the above base (110) is operated forward and backward, it is significant in that it is more helpful in the rehabilitation exercise of the rehabilitation patient.

The present invention enables universal rehabilitation by incorporating the pedaling and leg press push functions of a recumbent bicycle inspired by a recumbent cycle and a power leg press. In other words, the present invention can be said to have been developed as a universal rehabilitation cycle.

It should be easy for a person with physical disabilities to sit on exercise equipment, and the chair should not be too high. The present invention was developed to enable rehabilitation exercise by sitting stably on a seat (130) (chair) of an appropriate height for easy sitting, taking these factors into consideration.

The present invention ensures safety by allowing the weight of a rehabilitation patient to be supported by the backrest (150) and the seat (130) when the patient sits on the seat (130). The backrest (150) and the seat (130) faithfully perform the role of supporting the neck, waist, and hips for the rehabilitation patient to sit in the correct posture.

The present invention enables precise joint target exercise, etc. by performing exercise without the left-right reaction of the body of a rehabilitation patient and without the weight being applied when pedaling by turning the pedal (166) after sitting on a seat (130).

The present invention has various exercise methods and exercise intensity application functions. When pedaling by turning a pair of pedals (166), an automatic length adjustment function is provided so that exercise is possible even if the lengths of the left and right upper and lower limb joints are different, and thus appropriate rehabilitation exercise corresponding to the lengths of the left and right joints and muscle strength, etc. is possible. In particular, the present invention is more meaningful in that it is implemented so that appropriate rehabilitation exercise corresponding to the physical conditions of the left and right joints, muscle strength, hip joints of one leg, etc. of a rehabilitation patient is possible through an operating mechanism in which the pedals (166) rotate forward and backward as described above, rather than a backrest (150). The difficulty level is subdivided so that it can be applied to people without muscle strength, and there is an effect in which pedaling exercise can be performed jointly with both hands and feet (i.e., pedaling exercise can be performed jointly with the arms and legs).

Meanwhile, the present invention is configured such that a monitor-side connection support frame (182) is provided on the rear backrest frame (146), and a monitor (184) (LED monitor (184)) is mounted on the monitor-side connection support frame (182), so that the rehabilitation patient can operate the monitor (184) screen by touching (LED screen touching) or using a controller while sitting or lying on the seat (130), thereby enabling the rehabilitation patient to play a game or watch TV on the screen of the monitor (184) while performing rehabilitation exercises.

In these cases, rehabilitation patients can play games or watch TV while doing rehabilitation exercises to keep them from getting bored.

At this time, the monitor (184) is configured to be angle-adjustable by an angle-adjusting means in the monitor (184) side connection frame, so that the game posture angle can be adjusted, and due to the game posture angle adjustment, it is preferable to easily adjust the center of resistance position between the pedal (166) and the rehabilitation exercise part of the rehabilitation patient when pedaling the pedal (166) so that the rehabilitation exercise is not hindered while enjoying the game.

Meanwhile, as described above, the rear seat support frame (142) is coupled to the lower surface of the seat (130), the front end of the rear seat support frame (142) is coupled to the upper end of the rear rotational operating frame (144) via a hinge, and the lower end of the rear seat support frame (142) is connected to a pair of lower base bars (112) on the left and right sides of the base (110) via a hinge, so that when the rear backrest frame (146) is raised forward from the base (110) based on the lower hinge connected to the base (110) (i.e., the lower hinge connected to the lower base bar (112) of the base (110) to which the pair of backrest frame bars (146FB) on the left and right sides are connected), the rear rotational operating frame (144) is relatively rotated by the hinge connected to the rear seat support frame (142) and the hinge connected to the lower base bar (112). By being raised further upward, the seat (130) is supported more stably in a horizontal state in which it is raised, and when the rear backrest frame (146) is laid back from the base (110) based on the lower hinge connected to the base (110) (i.e., the lower hinge to which a pair of backrest frame bars (146FB) on the left and right are connected to the lower base bar (112) of the base (110), the rear rotational operating frame (144) is rotated to be laid down relatively further downward by the hinge connected to the rear seat support frame (142) and the hinge connected to the lower base bar (112), so that the seat (130) is relatively lowered further and supported more stably in a folded state.

Accordingly, when performing rehabilitation exercise by placing the buttocks on the sheet (130), the buttocks of the rehabilitation patient are supported more stably and firmly by the sheet (130), so that greater assistance can be provided in the rehabilitation exercise of the rehabilitation patient.

Meanwhile, FIG. 16 is a side view schematically showing the structure of a left-right variable rotation pedal type exercise device for rehabilitation exercise according to another embodiment of the present invention, and FIG. 17 is a plan view schematically showing the structure of a left-right variable rotation pedal type exercise device for rehabilitation exercise according to another embodiment of the present invention.

The present invention further includes a rear buffer structure (190) provided on the base (110) to absorb shock when the rear backrest frame (146) is tilted backward from the base (110).

The above rear buffer structure (190) is characterized by including a shock-up sleeve (192) having a lower end fixed to an upper surface of a rear cross bar (114) of the base (110) and arranged in an up-and-down direction; a shock-up bar (194) that is slidably coupled to the inside of the shock-up sleeve (192) and a portion of which is exposed to the upper end of the shock-up sleeve (192); and a shock-up spring (196) that is built into the inside of the shock-up sleeve (192) and has upper and lower ends in contact with the lower end of the shock-up bar (194) and the inner bottom of the shock-up sleeve (192).

At this time, the rear backrest frame (146) has a structure in which a backrest connection frame bar (146CB) is provided at the upper end of the left and right backrest frame bars (146FB), and the lower end of the left and right pair of backrest (150) frames of the rear backrest frame (146) is connected to the left and right pair of lower base bars (112) constituting the base (110) via a hinge, and the rear buffer structure (190) is arranged at a position where it meets the left and right pair of backrest frame bars (146FB) of the rear backrest frame (146). That is, the shock-up sleeve (192), the shock-up bar (194), and the shock-up spring (196) are arranged at a position where they meet the left and right pair of backrest frame bars (146FB) of the rear backrest frame (146), so that the upper portions of the left and right pair of shock-up bars (194) are arranged at a position where they can support the left and right pair of backrest frame bars (146FB) of the rear backrest frame (146) from below.

When the rear backrest frame (146) is tilted backward from the base (110) based on the lower hinge connected to the base (110) (i.e., the lower hinge connected to the left and right pair of backrest frame bars (146FB) to the lower base bar (112) of the base (110), the shock-up bar (194) supports the left and right pair of backrest frame bars (146FB) of the rear backrest frame (146), and the shock-up bar (194) is continuously pressed into the inside of the shock-up sleeve (192) by the load of the rear backrest frame (146) tilted backward, and the shock-up spring (196) is compressed and retained with elastic force, so that there is an effect of reducing the impact force that may occur when the rear backrest frame (146) is tilted backward abruptly from the base (110). In addition, there is an effect of preventing in advance the case where a rehabilitation patient with his/her back supported by the backrest (150) lies down and an impact force is applied to the rehabilitation patient due to the rear backrest frame (146) being suddenly laid down.

At this time, in the present invention, a buffer member (198) such as elastic urethane or sponge is further provided on the upper portion of the shock-up bar (194), so that the upper portion of the shock-up bar (194) does not directly contact the left and right pair of backrest frame bars (146FB) of the rear backrest frame (146), but rather the buffer member (198) contacts them, thereby preventing impact force or noise that may be generated when the upper portion of the shock-up bar (194) directly collides with the backrest frame bars (146FB) when the rear backrest frame (146) is laid down.

Meanwhile, when the rear backrest frame (146) is raised forward from the base (110) based on the lower hinge connected to the base (110) (i.e., the lower hinge to which a pair of backrest frame bars (146FB) on the left and right are connected to the lower base bar (112) of the base (110), the shock-up spring (196) is compressed and then unfolds by its own elastic restoring force, thereby causing the shock-up bar (194) to be pulled out again to the upper end of the shock-up sleeve (192), thereby enabling the rear backrest frame (146) and the backrest (150) to switch to a shock-up standby state that absorbs shock when they are tilted backward.

In addition, the present invention is characterized by further including an inner chamber (202) provided inside the backrest (150); a plurality of air blowing holes (204) penetrating through the inner and outer surfaces of the front backrest (150) seat (130) of the backrest (150) and communicating with the inner chamber (202); and an air blowing device (206) connected to the inner chamber (202) of the backrest (150) via a connecting pipe.

The above air blowing device (206) may be configured as a device having a blowing fan built into a fan case, and may be configured such that an inner chamber (202) inside a backrest (150) is connected to the fan case via a connecting pipe (CP) such as a flexible hose, so that air is introduced into the inner chamber (202) inside the backrest (150) according to the operation of the air blowing device (206) (i.e., rotational operation of the blowing fan) and the air is sprayed into a plurality of air blowing holes (204). At this time, an air inlet hole (150AH) is provided on one side of the backrest (150), and the connecting pipe (CP) is connected to the air inlet hole (150AH), and the connecting pipe (CP) is connected to an air blowing device (206), so that air can enter the air chamber (202) inside the backrest (150) by driving the air blowing device (206) and be sprayed through a plurality of air blowing holes (204). Preferably, a plurality of protrusions and concave grooves are provided on the outer surface of the front backrest (150) seat (130) of the backrest (150), and a plurality of air injection holes are formed in the concave groove portion, so that cool air sprayed through the air injection holes can be sprayed more smoothly to the back of a rehabilitation patient.

Accordingly, the present invention has the effect of allowing the rehabilitation patient to perform rehabilitation exercise in a more comfortable and pleasant environment by continuously cooling the back of the rehabilitation patient while performing rehabilitation exercise by blowing cool air through a plurality of air blowing holes (204) provided in the backrest (150) onto the back of the rehabilitation patient who is sitting with the buttocks on the seat (130) or lying down with the backrest (150) laid down.

It will be understood by those skilled in the art that the present invention is not limited to the above-described embodiments, and that various modifications and variations can be made without changing the gist of the present invention.

Accordingly, the embodiments described above are provided to fully inform a person having ordinary skill in the art of the present invention of the scope of the invention, and therefore should be understood to be exemplary and not restrictive in all respects, and the present invention is defined only by the scope of the claims.
