Abstract
Description
본 발명은 등받이 쿳션장치를 결합한 학생용 의자에 관한 것으로, 상세히는 등받이를 지지하는 프레임의 수직부를 분할한 후 탄성부재로 연결함으로서 탄성부재에 의해 등받이 쿠션이 이루어지도록 한 학생용 의자에 관한 것이다.The present invention relates to a student chair incorporating a back cushion device, and more particularly, to a student chair in which a back cushion is made by an elastic member by dividing a vertical portion of a frame supporting the backrest and connecting the elastic member.
일반적으로 학생들이 사용하는 의자는 내구성이 강한 금속 파이프로 프레임을 구성한 후 목재나 합성수지로 구성한 등받이 및 좌판을 결합한 구조로 이루어져 있다.In general, the chair used by students is composed of a frame made of durable metal pipe, and then combined with a backrest and a seat plate made of wood or synthetic resin.
이와 같은 구조는 매우 딱딱하고, 불편하여 장시간 사용시 허리 등에 통증을 유발하고, 주의력을 떨어 뜨려 산만해지기 쉬운 등 사용 만족도가 낮은 문제점이 있었다.Such a structure is very hard and inconvenient, causing pain in the lower back and the like when used for a long time, and there is a problem of low use satisfaction, such as being less distracted by distraction.
또한, 이들 의자는 평균적인 체형의 학생에 맞게 대량으로 생산되기 때문에 체형이 크거나 작은 학생들은 등받이 부분이 제 위치에 있지 않아 장시간 앉아 있을 때 더욱 더 고통을 느끼게 되는 문제점이 있었다.In addition, these chairs are produced in large quantities to fit the average body size of the student body size or small students have a problem that the back part is not in place to feel more pain when sitting for a long time.
본 발명은 이와 같은 종래의 학생용 의자가 갖는 문제점을 경제적으로 해결하기 위한 것이며, 특히 등받이에 쿳션기능을 부여함으로서 등을 편하게 받쳐 줄 수 있도록 할 목적을 갖는다.The present invention aims to economically solve the problems of the conventional student chair, and in particular, has an object to comfortably support the back by providing a cushion function to the backrest.
또한, 본 발명은 체형에 따라 등받이의 높낮이를 조절할 수 있도록 함으로서 체형에 따라 편한 상태로 조절하여 사용할 수 있도록 할 목적으로 안출된 것이다.In addition, the present invention has been made for the purpose of adjusting the height of the backrest according to the body shape to be used in a comfortable state according to the body shape.

이를 위하여 본 발명은 등받이를 지지하는 원통형 프레임의 수직부를 분할하고, 상기 프레임의 분활부에는 탄성재로 구성된 연결구로 연결한 구성의 쿳션장치가 결합된 학생용 의자를 제시한다.To this end, the present invention divides the vertical portion of the cylindrical frame for supporting the backrest, and provides a student chair coupled with a cushioning device of the structure connected to the connector consisting of an elastic material in the division of the frame.
상기 연결구는 원통형 프레임의 중공부에 연결구의 양단을 끼워 고정하는 구조로 이루어지고, 연결구는 탄성재로 구성함으로서 스프링과 같은 탄성을 발휘하여 등받이에 적적한 쿠션이 부여되도록 하는데 그 특징이 있다.The connector has a structure in which both ends of the connector is fixed to the hollow part of the cylindrical frame, and the connector is made of an elastic material to exert elasticity such as a spring so that an appropriate cushion is provided to the backrest.
또한, 본 발명은 상기한 분할 된 프레임의 하부측에 일정간격으로 걸림홈을 형성하고, 연결구의 프레임 증공부에 삽입되는 부분에 스프링의 탄발력을 받는 볼 을 결합하여 상기 볼이 걸림홈에 걸림으로서 단계적으로 등받이의 높이를 조절할 수 있도록 한 구성을 아울러 제시한다.In addition, the present invention forms a locking groove at a predetermined interval on the lower side of the divided frame, the ball is caught in the locking groove by coupling the ball receiving the spring force to the portion inserted into the frame cavity of the connector In addition, a configuration to adjust the height of the backrest step by step is also presented.
이하 첨부된 도면에 의한 실시례에 의해 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도1은 본 발명의 구조를 도시하기 위한 것이고, 도2는 본 발명이 적용된 의자를 도시한 것으로,본 발명은 " ∩ " 형태의 등받이 프레임(10)에 등받이(20)가 4결합되고, " ⊂ "형태의 좌판 프레임(30)에 좌판(40)이 결합되어 2각 구조의 다리(50)에 지지되는 형태의 학생용 의자에 적용된 것을 보인 것이다.Figure 1 is for illustrating the structure of the present invention, Figure 2 shows a chair to which the present invention is applied, the present invention is the backrest 20 is four coupled to the backrest frame 10 of the "∩" form, " It is shown that the seat plate 40 is coupled to the seat plate frame 30 in the form of "⊂" and applied to the student chair of the type supported by the legs 50 of the bilateral structure.
등받이 프레임은 원통형 파이프를 사용하여 좌판 프레임과 연속된 구조로 이루어지며, 외부로 노출되는 수직부를 절단한 후 여기에 탄성재로 이루어진 연결구(60)를 결합한 구성을 갖는다.The back frame is made of a continuous structure with the seat plate frame using a cylindrical pipe, and has a configuration in which a connector 60 made of an elastic material is coupled thereto after cutting a vertical portion exposed to the outside.
연결구(60)는 절단된 프레임을 연결시켜 연속되게 하고, 힘을 가했을 때 적당히 휘어지고, 힘을 제거하면 복원되도록 함으로서 등받이에 탄력이 부여되도록 하기 위한 것으로 다양한 소재가 적용될 수 있으며, 외부로 노출되는 몸통(61)부분과 프레임의 중공부에 끼워져 결합되는 결합부(62)로 이루어지며, 프레임을 관통하는 볼트(100)에 의해 체결됨으로서 프레임상에 견고하게 결합된다.The connector 60 is connected to the cut frame to be continuous, bend moderately when the force is applied, and to be restored when the force is removed so that the elasticity is applied to the backrest can be applied a variety of materials, exposed to the outside Composed of the body portion 61 and the coupling portion 62 is fitted to be coupled to the hollow portion of the frame, is fastened by the bolt 100 penetrating the frame is firmly coupled to the frame.
도3은 연결구의 실시례로서 내부에 판스프링(63)을 넣고 상하부에 결합부가 형성되도록 플라스틱으로 성형하여 외형을 구성한 구조를 보인 것이다.Figure 3 shows an example structure of the connector by inserting a leaf spring (63) inside and molded in plastic to form a coupling portion in the upper and lower parts.
상기 연결구는 외부로 노출되는 본체 부분이 ABS소재와 같은 엔지니어링 플라스틱 소재를 사용함으로서 부드럽고, 외부 형상과 균형을 이루며, 스프링작용을 하는 내부의 판스프링이 외부로 드러나지 않음으로서 마무리가 깨끗해지는 장점을 갖고, 매우 견고하여 학생들에 의해 함부로 다루어지더라도 거의 훼손되지 않는 특징을 갖는다.The connector has the advantage that the body part exposed to the outside is soft by using an engineering plastic material such as ABS material, the balance of the outer shape, the inner spring spring acting as a spring does not appear to the outside to clean the finish They are so sturdy that they are hardly tampered with by students.
상기 실시례는 상기한 연결구의 하부 결합부에 신축부(70)를 함께 결합한 구조를 보인 것으로 연결구와 동일한 소재를 사용하거나 금속재를 사용하여 연결구의 성형시 일체로 성형한다.The above embodiment shows a structure in which the expansion and contraction portion 70 is coupled together to the lower coupling portion of the connector, and is integrally formed when the connector is formed by using the same material as the connector or using a metal material.
상기 신축부에는 가로 방향으로 나사공(71)을 내고, 상기 나사공에 나사(72),스프링(73) 및 볼(74)을 결합하여 조립상태에서 상기한 볼(74)이 프레임상에 형성한 볼홈(11)에 걸리도록 함으로서 볼홈이 형성된 간격으로 등받이의 높낮이를 조절할 수 있도록 구성된다.The expansion and contraction of the screw hole 71 in the transverse direction, and the screw 72, the spring 73 and the ball 74 is coupled to the screw hole to form the ball 74 on the frame in the assembled state By being caught in one ball groove 11 is configured to adjust the height of the backrest at the interval formed ball groove.
도 4는 본 발명의 동작 상태를 도시한 것으로, 의자에 앉은 상태에서 등받이에 적당히 힘을 가하면 연결구 부분이 적당히 휘어지면서 탄력을 받고, 등을 편안 하게 압박하여 주게된다.4 is a view showing the operating state of the present invention, when a moderate force is applied to the backrest while sitting on a chair, the connector part is moderately bent and is elastically pressed to comfortably press the back.
또한, 적당한 힘으로 등받이 프레임을 누르거나 뽑아 주면 스프링이 수축하면서 상부 프레임의 삽입 깊이가 단계적으로 변화하여 체형에 따른 등받이의 높이를 조절할 수 있게 된다.In addition, when the back frame is pushed or pulled with a suitable force, the spring is contracted and the insertion depth of the upper frame is gradually changed to adjust the height of the backrest according to the body shape.
본 발명은 등받이에 쿳션기능이 부여됨으로서 장시간 앉아 생활하는 학생들의 피로를 현저히 감소시킬 수 있으며, 체형에 따라 등받이의 높낮이를 조절할 수 있는 효과를 갖는다.The present invention is provided with a cushion function in the backrest can significantly reduce the fatigue of students sitting for a long time, and has the effect of adjusting the height of the backrest according to the body type.
