Description

An exercise device that helps growth through stretching and vibration stimulation for the knee joint

The present invention relates to an exercise device that helps growth through stretching and vibration stimulation for the knee joint, and more particularly, provides a stretching effect by traction to the area around the thigh, calf, and knee joint of the human body and By applying heat and vibration stimulation to the popliteal region, it stimulates the muscles, ligaments and growth plates connected to the knee joint of adolescents in the growing age, and relaxes the muscles around the knee joint to help growth, especially in the thigh and calf. It relates to an exercise device that helps growth through stretching and vibration stimulation for the knee joint where traction is applied in a state in close contact with a large area according to the shape.

In recent years, as the lack of exercise and the increase in sedentary life, the problems caused by abnormal growth of the musculoskeletal system or growth retardation in children and adolescents in the growing stage are becoming serious. The best way to prevent this is to exercise and stretch properly. It is to strengthen the muscles around the joints or musculoskeletal system through self-healing power.

On the other hand, the growth plate (Physeal plate) is the part where the length growth occurs in the limb bones, located at both ends of the bones, in the form of cartilage tissue sandwiched between the bones, and in the fetus, all the limb bones are made of cartilage. As the cartilage grows, the middle part of the cartilage changes into bone and gradually spreads to both ends. This part is called the primary ossification center. As the cartilage cells located in the growth plate actively divide, cartilage gradually turns into bone at the center and both ends of the bone. The cartilage that remains in between becomes a growth plate, and then, as puberty passes, the growth plate also turns into bone, and length growth ends. Factors affecting the cell division of chondrocytes located in the growth plate include genetic predisposition, nutrients, hormones, exercise, and mechanical stimulation. .

Therefore, as the fetus grows into adolescence, it is important to provide sufficient nutrition, moderate exercise, and mechanical stimulation. Methods of receiving acupressure and massage are being proposed.

However, since the conventional exercise method requires regular exercise amount and time, it is difficult to implement for children or adolescents suffering from studies. There was a problem that the effect was not constant by being carried out depending on the power of a person as well as the inconvenience of receiving it. In order to improve these problems, various types of acupressure/massage machines that can receive acupressure/massage on their own have been developed and used in the past. constitutes

The vibration massager according to the prior art is a method of vibrating the acupressure tool using a driving source such as a vibration motor or a solenoid. In addition, it has the disadvantage of causing secondary pain due to the blow. In addition, in order to properly transmit the vibration of the acupressure tool to the body, the acupressure tool must be pressed with a certain force on the body part, so it is not only inconvenient to use but also requires a lot of force to use it continuously. There was this difficult problem.

On the other hand, the pneumatic massager uses the compressed air generated by the pump to repeatedly apply air pressure to the cuff configured to surround the user's body part, and most of the cuff is designed to cover body parts such as arms, legs, or waist. Since it is configured to repeatedly apply pressure to a part of the body through this by injecting and discharging air into the body, there was a problem that the effect of stretching could not be expected except for locally pressurizing a part of the body.

As a massage device for stimulating growth plates according to the prior art, there is a 'growth plate stimulation massage providing device for promoting growth and development' disclosed in Korean Patent Registration No. 10-1950148, and in claim 1 thereof, 'in the massage device, a user's body part' a body data calculation unit for calculating at least a portion of length-related information; a growth plate stimulation massage pattern determining unit for determining a growth plate stimulation massage pattern based on the calculated body length related information; a growth plate stimulation massage providing unit providing a massage based on the growth plate stimulation massage pattern; a body massage unit having at least one air cell and a massage module; and a leg massage unit including at least one air cell, wherein the leg massage unit is separated into an upper leg module and a lower leg module to have a vertically movable structure, and the body data calculation unit includes: a user's heel position a leg length determining unit for obtaining and determining a leg length based on this; and a height determining unit for acquiring the user's shoulder height and determining the height of the user based on the leg length and the shoulder height, wherein the growth plate stimulation massage pattern determining unit includes, the user's shoulder height, leg length and height A massage device for providing a growth plate stimulation massage that promotes growth and development by controlling at least a portion of the massage device based on at least one of.' is disclosed.

However, the growth plate stimulation massage device that promotes growth and development according to the prior art has a disadvantage in that there are restrictions depending on the installation space and use space because the structure is complex and bulky. In particular, the leg massage unit composed of an upper air cell, a middle air cell, and a lower air cell simply massages the calf, and there is a disadvantage that an effective stretching effect cannot be expected around the knee joint for height growth.

As another prior art, a 'massage device capable of stimulating and stretching the growth plate of adolescents in the growth stage' has been proposed through Republic of Korea Patent Publication No. 10-2178061, and in claim 1, 'in the massage device, at least one air cell' and a body massage unit having a massage module to massage the user's body; a leg massage unit having a plurality of air cells; and a control unit for controlling the operation of the massage device. Including, wherein the leg massage unit is provided separately as an upper leg module and a lower leg module, the control unit: at least one provided in the upper leg module in order to fix both sides of the lower end of the femur of the user seated in the massage device Inflating the air cell, inflating at least one air cell provided in the lower leg module to fix the ankle of the user seated on the massage device, and to stimulate the growth plate of the user's knee included in the upper leg module At least one air cell is inflated and the lower leg module is extended downward in a state in which at least one air cell included in the lower leg module is inflated. A massage device for determining an extension length of the lower leg module based on the determined leg length is disclosed.

However, since the prior art has to be used in a seated state, the structure is complicated and bulky, so there is a limitation on the installation place, and it is difficult to manufacture economically, so it is expensive.

In particular, as the air cell surrounding the user's leg is provided in the form of a pouch that is simply supplied with air and expands, it cannot closely adhere to the curved shape of the human body, causing pain or In addition to causing injury, it is difficult to provide effective stimulation to the growth plate distributed around the knee joint because it is a structure that extends the lower leg module by measuring the length of the leg by means of stimulation and simply the expansion and contraction of the air cell and sensing means. there was

As an example, the calf part has a partially convex shape by the muscle as it progresses from the thigh to the ankle in the leg of the human body, and the air cell according to the prior art is provided in the form of a straight tube into which the leg is inserted, or Since it is a structure provided in a 'U' shape so that parts can be placed on it, it cannot be closely attached to the shape of the legs of the human body. Due to the low pressure acting on the lower part of the body, it is difficult to implement a proper massage function, and it is not possible to apply uniform pressure to each body part where the upper and lower leg modules are located, resulting in discomfort and pain in use. There was a problem that caused dissatisfaction.

That is, since the upper extremity air cell 33 is provided in the form of a tube made of synthetic resin fabric, when it is expanded by air pressure, it has a disadvantage in that it cannot generate a uniform pressing force in response to the curved surface of the body.

For example, the thigh of the body becomes thicker as it goes from the part just above the knee toward the hip. In the case of a normal air cell, when inflation is made by air pressure, it is relatively thicker than the part just above the knee. As relatively higher air pressure acts on the body, local pain and discomfort are caused, which makes it impossible to perform restraint and fixation in a uniformly closely adhered state to the entire thigh (t) during traction.

Therefore, in the present invention, an upper limb adhesion pad 37 is provided on the inside of the upper extremity air cell 33 in order to solve these disadvantages, and the upper limb adhesion pad 37 is free from shape deformation due to the flowing material therein. Accordingly, as shown in FIG. 5 , it is possible to compensate for the curved part of the body.

The lower air cell 35 is filled with 30 to 90% of a liquid, gel, or granular fluid inside, and the shape is easily deformed by an external force by this fluid.

That is, the thickness gradually increases from the ankle to the calf of the body. When air pressure is supplied to the lower extremity air cell 35, the lower extremity adhesion pad 39 is uniformly adhered to the entire calf and the internal, fluid material is transferred to the body. As a result, as shown in FIG. 5, the curved portion is compensated to achieve a uniform close contact as a whole.
