Description

{Apparatus of Multi-joint for Supporting Lumbar Muscular Strength}

The present invention relates to a multi-joint lumbar muscle support device, and more particularly, to a multi-joint lumbar muscle support device using an elastic body.

In general, in the case of industrial sites, the frequency of heavy work added to the waist due to repetitive transport of loads is excessive, and industrial accidents and injuries caused by this are frequent. In the case of a medical field, when performing a nursing task, a high burden is performed on the lower back of the human body in order to wake up and support the patient.

Therefore, it is necessary to reduce the burden and prevent injuries through the lumbar muscle support device when performing an operation that places a high burden on the waist and transports loads in industrial, medical and real life.

As a conventional muscle aid or muscle aid device, Korean Patent No. 10-1516758, Japanese Patent Publication No. 2019-055033, Korean Patent Publication No. 2017-0006367, and the like are disclosed.

Korean Patent No. 10-1516758 is an upper limb muscle strength assisting device for maximizing user convenience, and is worn on the front, rear, right and left arms of the user's upper body, respectively. , It has a configuration having a first elastic member that assists the muscle strength of the user's right and left arm, and a second elastic member that assists the muscle strength of the user's right and left arm.

Japanese Patent Laid-Open No. 2019-055033 is a support wear and motion support system that can support the motion of the upper body and reduce the burden during the unloading operation of the user. A waist belt worn on the lower body and an upper side of the waist belt are connected to the upper body. It is composed of a left shoulder mount and a right shoulder mount that are worn like suspenders.

Korean Patent Laid-Open Patent No. 2017-0006367 is a working muscle strength aid to protect the bones and muscles of the lower back from pain and injuries. A suspension band worn on the upper body, a waist band worn on the waist, and a thigh fixing band worn on the lower body , It is composed of a suspending band and a central band connecting the waist band and the thigh fixing band to each other, and a ring that can adjust the tension of the central band by fixing a specific position of the central band.

These conventional techniques, because the elasticity of the band is fine, because it is a muscle strength aid device using an elastic body in the form of a clothing/band, it does not play a large role in supporting workers and supporting muscle strength, and a large force such as a spring/gas cylinder may act, but in a solid form. In the case of the designed strength assisting device, it can interfere with the movement of the wearer, and in the case of the muscle assisting device that requires a large amount of power, the weight of the device is reduced due to each additional power system (spring, hydraulic pressure, motor, gas cylinder, etc.) It is a configuration that has technical limitations due to a problem that is high and acts as a burden on the user.

Therefore, there is a need to develop a new configuration of a muscle support device that overcomes the technical limitations of the prior art.
