등받이 의자{Chair with backrest}Backrest Chair {Chair with backrest}

본 고안은 등받이 각도의 조절이 가능한 의자에 관한 것으로서, 보다 자세하게는 정해진 등받이 각도 내에서 유동가능한 범위인 틸팅(각도조절) 텐션 조절이 용이하고 소음이 없는 등받이 의자에 관한 것이다.The present invention relates to a chair capable of adjusting the backrest angle, and more particularly, to a backrest chair that is easy to adjust the tilting (angle adjustment) tension that is movable within a predetermined backrest angle and has no noise.

본 고안의 등받이 의자는 등받이가 의자의 착석판과 분리 형성되고 연결부재에 의하여 등받이의 각도 조절이 가능한 의자를 가리킨다.The backrest chair of the present invention refers to a chair whose backrest is formed separately from the seating plate of the chair and the angle of the backrest can be adjusted by the connection member.

일반적으로 등받이 의자의 각도 조절은 회전체에 부착되는 가스 스프링 등과 같은 신축장치를 외부 레버를 이용하여 구동함으로써 가능하며, 각도 조절 후에도 사용상의 안락감을 위하여 등받이 자체가 탄성체의 복원력을 이용하여 일정 각도의 유동범위를 갖도록 설계된다.In general, the angle of the backrest chair can be adjusted by using an external lever to drive a telescopic device such as a gas spring attached to the rotating body, and even after the angle adjustment, the backrest itself has a certain angle by using the restoring force of the elastic body. It is designed to have a flow range.

그러나 종래 등받이 의자의 자체 탄성 복원력은 스프링에 의하여 구현되므로 등받이 사용시 움직임에 따라 소음이 발생하고, 많은 부품이 필요한 구조로서 의자의 회전수명을 단축시키는 문제가 있다.However, since the conventional elastic restoring force of the backrest chair is implemented by a spring, noise occurs as the backrest moves, and there is a problem of shortening the rotational life of the chair as a structure requiring many parts.

또한 상기 자체 탄성 복원력은 사용자에 따라 요구되는 정도가 다양하나, 종래에는 채택되는 탄성체의 복원력에 따라 일률적인 틸팅(각도조절) 텐션이 설정되어 사용자의 다양한 요구에 부응하지 못하며 착석시 안락감을 저해하는 문제가 있었다.In addition, the self-elastic restoring force is required to vary depending on the user, but conventionally, according to the restoring force of the elastic body is adopted, a uniform tilting (angle adjustment) tension is set to meet the various needs of the user does not satisfy the comfort when sitting There was a problem.

본 고안은 상술한 종래 등받이 의자의 소음 및 틸팅(각도조절) 텐션 조절 상의 문제점을 해결하고자 하는 것으로서, 무소음의 탄성체를 도입하고 틸팅(각도조절) 텐션의 조절을 용이하게 하는 구성을 도입하여 등받이의 각도 조절 뿐만 아니라, 자체 탄성 복원력의 자유로운 조절을 가능케 하는 것을 목적으로 한다.The present invention is to solve the problems of the noise and tilting (angle adjustment) tension adjustment of the conventional backrest chair, introducing a noiseless elastic body and introducing a configuration to facilitate the adjustment of the tilting (angle adjustment) tension of the backrest In addition to the angle adjustment, it aims to enable free adjustment of the self-elastic restoring force.

상기 착석판(1)과 등받이(3)는 분리 형성되어 등받이 지지부(2)에 의해 연결되어 있으며, 등받이 지지부(2)는 착석판(1)의 하부에서 고정되고, 타단부인 등받이 연결부(21)는 절곡되어 등받이 하부에 결합한다.The seating plate 1 and the backrest 3 are separately formed and connected by the backrest support 2, and the backrest support 2 is fixed at the bottom of the seating plate 1, and the other end of the backrest connecting portion 21 is provided. Is bent and joined to the lower back.

즉, 등받이 지지부(2)는 등받이와 결합하는 일 단부인 등받이 연결부(21)가 절곡되어 평행하는 양축의 지지체를 포함하며, 측면에서 관찰할 때 "ㄴ"자로 형성되고, 착석판(1) 하부에서는 양축이 만나 하나의 연결축(22)을 형성함으로써 착석판 하부를 바라보면 "ㄷ"자 형상으로 형성된다.That is, the back support 2 includes a support of both shafts in which the back support connecting portion 21, which is one end coupled with the back support, is bent and formed in parallel, and is formed as a letter “b” when viewed from the side, and the seating plate 1 lower part. In the both shafts meet to form a connecting shaft 22 to look at the seating plate is formed in a "c" shape.

상기 연결축(22)은 토션바(4)로 감싸져 있고, 토션바(4)의 내부(41)는 고무가 충진되어, 고무 가운데에 밀착 결합한 상기 연결축(22)이 상기 고무의 탄성 복원력에 의해 착석시 등받이의 틸팅(각도조절) 텐션을 제공하게 된다.The connecting shaft 22 is wrapped in the torsion bar 4, the inner 41 of the torsion bar 4 is filled with rubber, the connecting shaft 22 is tightly coupled to the center of the rubber elastic restoring force of the rubber By the seat to provide a tilt (tilting) tension of the backrest.

The torsion bar 4 receives the connecting shaft 22 therein as a hollow tube, and is filled with rubber and coupled to the connecting shaft. As shown in FIG. 4, two torsional cylinders supporting a part of the connecting shaft are provided. The tube can be filled with rubber to support the connecting shaft.

토션바(4)는 내부에 고무를 충진한 관체가 연결축과 동일한 방향에서 연결축을 수용하여 밀착함으로써 연결축에 고무의 비틀림을 전달하는 구조이면 족한 것으로서, 이를 충족하는 것이라면 도면에 도시된 이외에도 다양한 형태로 구현할 수 있다.The torsion bar 4 is sufficient to have a structure in which the rubber-filled tubular body transmits the torsion of the rubber to the connecting shaft by receiving and contacting the connecting shaft in the same direction as the connecting shaft. It can be implemented in the form.

그리고 상기 토션바(4)는 일측으로 회전하면서 내부의 고무가 비틀려 연결축을 강하게 조이고, 반대로 회전시키면 토션바(4)와 연결축의 결합이 느슨하게 되면서 등받이의 틸팅(각도조절) 텐션을 조절할 수 있는 것인바, 토션바(4)를 회전시키는 텐션조절부(5)가 토션바의 상부 외측에 수평축(42)과 수직방향으로 결합하게 된다.And the torsion bar (4) is rotated to one side while the internal rubber is twisted to tighten the connection shaft strongly, if the reverse rotation loosens the coupling of the torsion bar (4) and the connection shaft can adjust the tilting (angle adjustment) tension of the backrest That is, the tension adjustment unit 5 for rotating the torsion bar 4 is coupled to the vertical axis and the horizontal axis 42 on the upper outer side of the torsion bar.

텐션조절부(5)는 다수의 연결부재로 이루어져 길이 조절이 가능한 것으로서, 토션바의 수평축(42)과 수직결합하고 있어 신축시 토션바(4)를 정해진 위치에서 일정 범위(바람직하게는 회전거리로는 26 ~ 30mm가량, 회전각도로는 36 ~ 40°가량) 회전시킬수 있는바, 본 고안에 따른 텐션조절부의 기술적 특징은 토션바의 수평축(42)과 수직방향으로 연결되어 신축을 통해 토션바를 회전시키도록 연결되고 사용자가 의자 전단부에서 조절레버(53)를 통해 수동으로 틸팅(각도조절) 텐션의 조절이 가능하도록 한다는 것이다.The tension adjusting part 5 is made of a plurality of connecting members, which can be adjusted in length, and are vertically coupled with the horizontal axis 42 of the torsion bar, so that the torsion bar 4 is stretched at a predetermined range (preferably a rotational distance) when stretched. Furnace is about 26 ~ 30mm, the rotation angle is about 36 ~ 40 °) can be rotated, the technical features of the tension control unit according to the present invention is connected to the vertical axis of the torsion bar in the vertical direction connected to the horizontal axis (42) It is connected to the rotation and allows the user to manually adjust the tilting (angle adjustment) tension through the adjustment lever 53 at the front end of the chair.

상기와 같은 나사결합부의 도입은 원가 절감에 기여하고 구현이 용이하며, 나사산의 회전을 통해 회전 정도를 미세하게 조정할 수 있어 사용자별 최적화된 틸팅 텐션의 조정이 가능하며, 부품이 간소하여 제품의 내구성에 긍정적인 영향을 미친다. The introduction of the screw coupling part contributes to cost reduction and is easy to implement, and it is possible to finely adjust the degree of rotation through the rotation of the thread, so that it is possible to adjust the tilting tension optimized for each user. Positively affects.

본 고안에 따른 텐션조절부는 그 신축거리의 조절로 손쉽게 텐션조절범위를 극대화할 수 있는바, 예를 들어 상기 나사결합부(52) 및 나사산(54)의 길이를 확장하면 텐션조절범위를 확대할 수 있는 것이다.The tension adjusting unit according to the present invention can easily maximize the tension adjusting range by adjusting the stretch distance, for example, by extending the length of the screw coupling portion 52 and the thread 54 to expand the tension adjusting range. It can be.
