Description

의자 등받이 {The back of a chair}Chair back {The back of a chair}

본발명은 학생용, 사무용 등의 의자 등받이에 관한 것으로, 좀 더 구체적으로는 의자 등받이를 3쪽으로 분할 구성하되, 등의 좌·우측을 감싸 받쳐주는 좌·우등판과 척추를 받쳐주는 중심등판으로 구성하고, 중심등판이 압축스프링에 의해 쿠숀작용이 원활하게 이루어지게 함으로써, 의자에 앉아 등을 기댓을때 좌·우등판이 인체의 등 좌·우측을 감싸 편안하게 받쳐주고 중심등판이 척추부분에 밀착되어 앉은 자세를 바로 잡아줄 뿐만 아니라 매우 편안하게 하며, 자세교정 효과도 발생되게 하기 위한 것이다.The present invention relates to a chair back for students, offices, etc. More specifically, the chair back is divided into three sides, and the left and right plates that cover the left and right sides of the back and the center back that support the spine. The central back plate is cushioned by the compression spring to make the cushion smoothly. When sitting on a chair, the left and right side boards comfortably support the left and right backs of the human body. In addition to correcting the sitting posture is very comfortable, and posture correction effect is to occur.

주지된 바와 같이 통상 사용되고 있는 학생용 및 사무용 의자의 등판은 단순히 허리 또는 허리를 포함한 등을 받쳐주도록 구성되어 있어, 장시간 앉아 공부를 하거나 업무를 볼때 허리와 등이 쉬 피로해지는 경향이 따르고, 또 자세가 흐트러지게 되어 심할 경우 허리 또는 척추가 휘는 경우도 따르게 되는 등의 문제점이 따르게 된다.As is well known, the backs of student chairs and office chairs that are commonly used are simply configured to support the back including the waist or the waist, so that the back and the back tend to become tired easily when studying or working for a long time. If it is distracted to be severe, it will be accompanied by problems such as bent back or spine.

한편, 상기한 일반 의자의 폐단을 해소코자 개발된 것으로서 공고번호 93 - 10033 호도 있는데, 이는 의자 등받이를 종방향으로 2등분하여 2개의 등판으로 구성하고, 각각의 등판이 합성수지와 탄성고무등을 결합부착하여서 된 결합구와 탄성기능을가진 중간가로대에 의해 등의 좌·우측 부분을 감싸지지하도록 구성한 것으로, 일반의자보다는 안락감이 뛰어나고 편안하지만 척추부분을 바로 지지하여 주지 못하는 폐단이 따를수 밖에 없고 또 중간가로대와 2개의 등판 사이에 설치되는 결합구가 합성수지와 탄성고무를 강력접착제나 열로써 접착시킨 것이기에 제조과정이 복잡하고 번거로워 원가를 높일수밖에 없는 폐단도 따랐던 것이다.On the other hand, it was developed to solve the above-mentioned end of the general chair No. 93-10033, which is divided into two backrests in the longitudinal direction of the chair back, consisting of two backplates, each of which combines synthetic resin and elastic rubber, etc. It is designed to be wrapped around the left and right parts of the back by the attached fittings and the middle side with elastic function.It is more comfortable and comfortable than general chairs, but it has no choice but to follow the end of the lungs Since the joints installed between the crossbars and the two backboards were made of strong adhesives or heat-bonded synthetic resins and elastic rubbers, the manufacturing process was complicated and cumbersome, leading to a cost increase.

본발명은 상기한 종래의 제반문제점을 감안하여 발명한 것으로, 특히 학생용, 사무용 의자의 등받이를 3쪽으로 분할구성하되, 등의 좌·우측부분을 감싸주면서 지탱하는 좌·우등판과 척추부분을 받쳐주는 중심 등판으로 분리구성하여 좌·우등판에는 비교적 연질의 합성수지로써 결합구를 형성하고 중심 등판에는 탄성장치를 설치하여 의자에 앉았을때 매우 편하면서 안락감을 느낄수 있게 하며, 더불어 의자에 앉아 공부나 업무를 장시간 하더라도 척추가 휘거나 변형될 염려가 없도록 하려는데 그 목적이 있는 것이다.The present invention has been invented in view of the above-mentioned conventional problems. Particularly, the backrest of the student and office chair is divided into three sides, and the left and right plates and the spine supporting the left and right sides of the back are supported. The main structure is divided into a central back panel, and the left and right panels form relatively soft synthetic resins, and the coupling unit is equipped with an elastic device in the center back panel so that the user can feel comfortable and comfortable when sitting on the chair. Even if it is for a long time, so that there is no fear of bending or deformation of the spine is the purpose.

또한 전술한 결합구를 종래처럼 두가지 소재를 결합시키지 아니하고 한가지 소재로서 형성하고 동시에 탄성력, 복원력은 종래에 비하여 뒤지지 않게함으로써 제작이 종래보다 간소화되면서 기능은 한층 더 배가 되게 하여 신뢰성을 극대화 시키려는데도 목적이 있는 것이다.In addition, the above-mentioned coupling tool is formed as one material without combining the two materials as in the prior art, and at the same time, the elastic force and the restoring force are not inferior to the conventional ones. It is.
