Description

Leg length mismatch compensation device for pedal type fitness equipment}

The present invention relates to a lower extremity immobilization correction device for a pedal-type exercise device, and more particularly, to a rehabilitation exercise device equipped with a pedal used to correct or treat spinal disorders, or a use problem due to a difference in leg length when using a bicycle or indoor cycle, etc. The present invention relates to a lower extremity immobilization correction device for pedal-type exercise equipment, which can be expected to correct and treat spinal diseases caused by gait disorders by eliminating discomfort and enabling stable pedal movement.

As more and more modern people sit and work in the same posture for long periods of time due to lack of exercise, one of the frequently occurring diseases is back pain caused by discs and shoulder pain caused by excessive movements of the shoulders and arms. ) and muscle pain. In particular, office workers and students who sit for a long time are suffering from spinal diseases.

On the other hand, the spine is composed of parts such as a vertebra that serves as the central body, a bow-shaped vertebral arch protruding from here to the rear and upper, and several projections. cavities) are formed, and spine diseases occur due to maintaining the wrong posture for a long time, muscle aging, or strong external shock. , The cause can be found in living habits such as sitting, standing or sleeping posture, and in the case of children and adolescents in the growing period, if there is an abnormality in the spine, the growth line is put under pressure, and accordingly, the secretion of growth hormone is not smooth. Failure to do so may lead to problems that impede growth promotion.

Methods for treating these spinal diseases include physical therapy to strengthen muscles, acupressure therapy to ensure smooth blood circulation by stimulating acupoints, or relaxation by relaxing the intervertebral discs that have been pressed by widening the gap between the narrowed vertebrae. There are traction treatments that correct the body shape.

On the other hand, acupressure or massage (massage) is a kind of manual procedure that corrects the body's modulation by directly giving mechanical stimulation to the skin in a certain way using the hands to cause a bioreaction to treat diseases and improve health (手技施術), acupressure massage promotes circulation of blood or lymph, boosts metabolism, enhances tissue nutrition, excretes waste, and enhances resistance. This tactile stimulation (觸壓刺戟) stimulates the nerves and acts as an analgesic, so it promotes the recovery of paralyzed nerves and has the effect of correcting the modulation of internal functions.

However, since most of these acupressure massages cannot be performed by the person receiving treatment alone, there is a problem in that the effect is not constant because it is performed by relying on the power of a person as well as the inconvenience of having to receive type help.

In order to improve this, various types of acupressure massagers that can receive acupressure massage by themselves have been developed and used in the past. In the case of a massager, it is a method of repeatedly hitting (tapping) a part of the body, so it has a disadvantage of not only having a low acupressure effect but also causing secondary pain by hitting. Since the part must be pressed with a certain force, not only the inconvenience in use is great, but also the continuous use is difficult due to the force.

In addition, in the case of an air pressure massager, pressure is repeatedly applied to a part of the body by injecting and discharging air into a cuff designed to cover a body part such as an arm, leg or waist of the body, and simply a part of the body Since it is only a massage, it is difficult to expect acupressure effects such as stimulating acupuncture points, and it is cumbersome to use because it must be worn on the arms, legs, or waist of the body. Although there is a treatment device equipped with a belt-type cuff that is inflated and provided with a traction force, it is also inconvenient to use because it must be worn on the neck or waist, and it is difficult to respond quickly in case of excessive pneumatic action, and sufficient traction effect can be obtained. There was a problem that the treatment effect was low according to the absence.

That is, the most ideal treatment and correction method to prevent spinal diseases is to regularly perform stretching exercises that stretch the entire body to correct the body shape by natural healing power resulting from the relaxation of muscles and skeletons. Prior art for this As an example, there is a chiropractic exercise device disclosed in Korean Patent Registration No. 0711104. This chiropractic exercise device is provided with a lower extremity exercise device that allows the user to lie down and exercise the lower extremities, a bed on which the user can lie down, and a pelvic belt that fixes the user's waist.

This pedal-type rehabilitation exercise device allows the user to fix the waist in a lying position using a pelvic belt and roll the pedal while lying on the bed, thereby repeatedly relaxing and restoring the human spine and strengthening the supporting muscles around the spine. and a therapeutic effect can be obtained.

However, in the pedal-type exercise device according to the prior art, the user performs a pedaling operation by placing the left and right feet on the respective pedals disposed on the left and right sides for pedaling. In the case of those who have, there was a problem that the pedaling operation was impossible.

In other words, the difference in the length of the left and right legs is called immobility, and it means that one leg is longer or shorter than the other. It is not uncommon for such immobility to occur temporarily in the growth period, but if the difference in length is more than 2 cm, there may be a clinical problem. If immobility occurs and the difference in leg length between the left and right legs is more than 2 cm, the shoe heel of the shorter leg can be raised, surgery to prevent the growth plate of the normal leg from growing at the time the bone growth is completed, or lower extremity extension surgery can be performed. .

Such lower extremity immobility not only causes discomfort in walking, but also causes various spinal diseases such as hip joint stiffness as well as compensatory scoliosis in which the spine is twisted as the pelvis is twisted when standing or walking.

Therefore, in the case of immobilized lower limb patients, above all, exercise is required for the twisted pelvis, spine, and the entire muscles around the spine through rehabilitation exercises, but in the case of the pedal-type exercise device according to the prior art, due to the difference in length of the left and right legs There was a problem that made it difficult to use.

Here, as the magnetic plate 31 provided on the lower surface of the safety separation part 30 is attached to the movable step part 13, it maintains the attached state so that the user's foot does not easily fall off the pedal while pedaling, and also maintains the magnetic force. This is to prepare for a case in which the user has to quickly remove his/her foot from the pedal due to an unexpected accident or safety reasons by allowing the user to fall off the pedal when the above external force is applied.

Since the height of the pedal can be arbitrarily adjusted in using the pedal-type exercise device according to the present invention configured as described above, even in the case of immobilized users with different leg lengths, the height suitable for them can be adjusted. As the pedal position can be adjusted, stable and smooth pedal movement is possible.

Therefore, since the ease of use and exercise effect of the pedal-type exercise device can be improved, the treatment and correction effect for scoliosis and related diseases caused by lower extremity immobility can be improved.
