It relates to a chair fixing structure for a rehabilitation exercise machine whose structure is improved to prevent a fall accident of a rehabilitation patient seated in a sitting chair.

In general, a general upper and lower extremity peristaltic exercise device includes a pair of pedals on which feet are seated and a pair of handles that can be gripped by hand.

Therefore, when a user applies force in a predetermined direction while placing both feet on the pedal and holding the handle with both hands, the arms and legs can be simultaneously exercised while each pedal and handle reciprocate along a preset trajectory.

Compared to exercises using ordinary exercise machines that separate the upper or lower body, the upper and lower limb peristaltic exercise device has the advantage of not only increasing the amount of exercise by simultaneously exercising the arms and legs, but also enabling effective whole-body exercise.

Therefore, in recent years, an attempt has been made to apply the upper and lower extremity peristaltic exercise device to rehabilitation treatment for the physically handicapped or the elderly.

However, the conventional upper and lower limb peristaltic exercise device is focused on increasing the amount of exercise for healthy general people, and the pedal and handle are configured to reciprocate while drawing a simple straight or arc-shaped trajectory, so the body parts used for exercise are limited. There was a problem that it was difficult to apply to rehabilitation treatment that requires the use of muscles in various parts.

As the prior art for improving this, as disclosed in Korean Registered Patent Publication No. 10-1115545 "Upper and lower extremity peristaltic exercise device for rehabilitation treatment" (registration date: 2012.02.06), a frame; a first shaft fixedly installed through the upper side of the frame; a second shaft rotatably installed through the frame; a pair of lower extremity links, one end of which is rotatably connected to both ends of the first shaft so that a pedal formed at the other end can rotate along an arc-shaped trajectory; a pair of upper limb links having one end connected to interlock with the lower limb link and having a handle formed at the other end; Consists of a pair of rotating members fixed to both ends of the second shaft and integrally rotating with the second shaft, each rotating member having an eccentric connection connected to each upper limb link by a second shaft pin at an eccentric position. It is configured to include a rotation link; the eccentric rotation link limits the rotation range so that the pedal of the lower extremity link reciprocates within a predetermined section, and according to the rotational motion of the lower extremity link, the handle of the upper extremity link interlocks in a closed curve trajectory to induce it to do so.

Other prior art related to the conventional lower extremity rehabilitation device, as described in Korea Patent Registration Registration No. 10-1494685 "lower extremity training exercise device" (registration date: 2015.02.12), the frame; a drive shaft that is rotationally driven by the rotational driving force of a drive motor mounted on the connecting rod of the frame; a rotational shaft driven by rotation by receiving rotational force of the driving shaft driven by the driving motor through a connection means; a lower extremity support on which the lower extremity of the user is seated and forcibly moving the lower extremity of the user with the rotational force of the driving shaft and the rotating shaft; a plurality of first interlocking means for converting the rotational force of the drive shaft into a crank motion force and transmitting it to the lower extremity support; and a plurality of second interlocking means for transmitting the rotational force of the rotational shaft to the lower extremity support, wherein the first interlocking means is connected to a rotational plate provided at both ends of the driving shaft and one end connected to an edge of the rotational plate. and an interlocking bar having the other end connected to the lower limb support and being cranked by the rotational force of the drive shaft, a connecting bar connected to the upper end of the lower limb support, and a support supported by the frame and supporting the forward and backward movement of the connecting bar. It is composed of a block, and the second interlocking means includes an eccentric cam provided at both ends of the rotating shaft to rotate eccentrically, a transmission bar contacting the outer circumferential surface of the eccentric cam and transmitting the eccentric rotational force of the eccentric cam, and the transmission It consists of a control plate for converting the rotational motion of the bar into an angle adjusting force of the lower extremity support and transferring it to the support block.

A first interlocking bar having a handle bar having a handle on the top of the first interlocking bar connected to support rotation of the crank and a first support bar connected by a connecting shaft to a fixing bar protruding from the front of the casing and having a handle bar having a handle on the upper portion, which is interlocked and rotated via a link member, A second support bar disposed on the right side, rotated in conjunction with the first rotation body via a link member, and coupled with a connecting shaft to a fixing bar protruding from the front of the casing is connected to support crank rotation, and a handle bar having a handle at the top A second interlocking bar provided, and one side pedal detachably coupled to one of the first and second support bars and supported by the foot of the hemiplegic patient, and the movement of the other pedal on the opposite side of the casing is transmitted to the one side pedal supported It is provided with interlocking means for selecting and exercising the user's lower limbs.

However, in the above prior art, the user's left upper limb and left lower limb are interlocked, and the right upper limb and right lower limb are interlocked. Since it is a structure that interlocks together in the same direction, there is a disadvantage in that the rehabilitation effect is somewhat weak because there is a difference from the normal walking motion of normal people.

In addition, in the prior art, although the user's exercise effect is variable according to the user's physical condition, the existing rehabilitation apparatus provides the same exercise load to the user, thereby reducing the efficiency of the rehabilitation exercise.

In the existing prior art, if the user is an elderly person or a rehabilitation patient without strength in the upper and lower extremities, safety accidents such as the user falling to the main body and colliding with the main body as the pedal is rotated while the user gets off from the seat after the rehabilitation exercise is completed may occur.

In addition, the existing prior art requires a structure capable of moving the seating part forward and backward toward the base in order to adjust the distance between the base and the seating part on which the rehabilitation patient is seated. It is necessary to prevent safety accidents in which rehabilitation patients fall.
