Description

Device for stretching ankles and calves

The present invention relates to a calf and ankle stretching device, and more particularly, to a calf and ankle stretching device capable of reinforcing the ankle and calf muscles using repetitive rolling motions, will be.

The calf is the part of the back muscle between the knee and ankle. It consists of the gastrocnemius, the branch muscle, the flexor flexor, the flexor flexor muscle, and the posterior tibialis muscle. In addition, the foot muscles, intramedullary muscles, Muscles such as extensor muscles, intestines and extensor muscles. These calves play a very important role because they are the first to receive shocks caused by human body upright walking. Especially, depending on how the shock is absorbed, the shock transmitted to the whole body also changes. Therefore, . Therefore, it is very important to restrain the fatigue that occurs in the calf quickly and to maintain the normal length, elasticity, flexibility, and strength, so as to prevent posture change and maintain a healthy body.

On the other hand, the vertebra connects the head bone to the pelvic bone to form the central axis of the human body. It supports the body, maintains equilibrium, and protects the spinal cord from the brain to the spine. Most people have a spinal structure that is unbalanced by their bedtime attitudes and bad habits of sitting. When the balance of the spine is broken, the shape of the structure changes, making it difficult to perform the above functions, and causing various diseases such as digestive disorders, inhibition of liver function, memory loss, concentration problems, fatigue and boredom. The structure of the vertebrae is s-shaped when viewed from the side, and plays an important role in the kinematics of the body. Therefore, it is important to maintain the S-shaped bend of the spine through proper sleeping and sitting postures.

However, it is difficult to maintain the right attitude for modern people who have a lot of chair life as the industrial society develops, and it is difficult to provide conditions such as time and place for exercising for health by solving stress and fatigue.

Accordingly, in Korean Patent Registration No. 10-1237373, a leg-like muscle strengthening mechanism of a leg capable of exercising in a sitting position without being restricted by a place has been invented. However, the calf muscle strengthening apparatus of the leg does not have a function for exercising the waist, so there is a need to provide a separate waist exercise apparatus.

Korean Utility Model Publication No. 20-2010-0004378 also discloses a rotary calf exercise device capable of rotating the calf and rotating the waist. However, the rotating calf exerciser has an acute angle of the ankle and the calf is stretched, and there is a waist strength and a stretching effect through the rotation of the waist, but there is no function to maintain and correct the curved shape of the vertebra, and the strength of the calf and ankle The effect for the sake of this has a disadvantage that it can not be seen.

When the exerciser 3 is to be used for calf movement, the foot plate 250 should be mounted on the body 1102. The first and second sliding groove engaging portions 257 and 259 of the foot plate 250 are slidably mounted on the first and second sliding grooves 130 and 140, respectively. Since the interval between the feet is different according to the user, when adjusting the position of the foot plate 250, the user may adjust the foot plate 250 by moving the foot plate 250 in the lateral direction. The foot plate 250 can be moved along the first and second sliding grooves 130 and 140 when the force applied by the user in the lateral direction to the foot plate 250 is larger than the elasticity modulus of the spring 263. That is, the spring 263 of the position movement restricting unit 260 must transmit a force higher than the elastic modulus of the spring 263 when the user pushes and pulls the foot plate 250 in the lateral direction to adjust the position of the foot plate 250 Contracted. The spring 263 is retracted and the position restricting groove contact member 261 is inserted into the through hole 270 so that the foot plate 250 is moved in the direction in which the user pushes. When the footrest 250 is moved in the user's pushing direction and reaches the adjacent position movement restricting groove 127, the position restricting groove contact member 261 protrudes by the retracted spring, do. However, since the direction in which the external force for rolling the body is applied is perpendicular to the sliding movement direction of the foot plate, there is no possibility that the foot plate is moved by rolling during the calf movement.

The above-described calf and ankle stretching device according to the present invention can be stretched and muscular strengthened by an ankle and a calf by rolling back and forth repeatedly, or can be placed on a user's waist to correct the curved shape of the spine inherently The state has a complex function, which has the advantage that it can be carried and used efficiently.

In addition, the calf and ankle stretching mechanism according to the present invention has a warming means, and can show a fomenting effect when exercising the calf or using the spine pillow. By preventing the foot from falling off during rolling for the calf movement by the separation- Can be prevented.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims. It will be appreciated that embodiments are possible. Therefore, the scope of the true technical protection of the present invention should be determined by the technical idea of the appended claims.
