Description

의자의 각도조절장치{angle control apparatus of chair}Angle control apparatus of chair

본 고안은 등판과 좌판의 각도를 조절하는 의자의 각도조절장치에 관한 것으로, 더 상세하게는 각도조절장치의 구조를 개선하여 등판의 각도조절이 부드럽고 원활하게 이루어지도록 하고, 또한 좌판의 경사각도를 조절할 수 있도록 하여 사용자의 편리함과 안락감을 크게 향상시킬 수 있도록 한 의자의 각도조절장치에 관한 것이다.The present invention relates to an angle adjusting device of a chair for adjusting the angle of the back plate and the seat plate, and more specifically, to improve the structure of the angle adjusting device so that the angle adjustment of the back plate is made smoothly and smoothly, and also the inclination angle of the seat plate It relates to an angle adjusting device of a chair to be able to adjust to greatly improve the convenience and comfort of the user.

일반적으로 의자는 사용자의 엉덩이를 받쳐주는 좌판과, 상기 좌판의 후방에 설치되어 사용자의 허리와 등을 받쳐주는 등판과, 상기 좌판의 하부에 높이조절이 가능하도록 설치되는 다리와, 상기 좌판의 양측에 설치되어 사용자의 팔을 받쳐주는 팔걸이와, 상기 좌판과 등판의 각도를 조절하는 각도조절장치로 크게 이루어진다. 이때, 상기 각도조절장치에는 높이조절레버와 각도조절레버 및 로킹부재가 설치된다.In general, a chair includes a seat plate supporting the user's hips, a back plate installed at the rear of the seat plate to support the user's waist and back, legs installed at a lower portion of the seat plate to enable height adjustment, and both sides of the seat plate. Installed in the armrest supporting the user's arm, and made of a large angle adjusting device for adjusting the angle of the seat plate and the back plate. At this time, the angle adjusting device is provided with a height adjusting lever, an angle adjusting lever and a locking member.

In this case, as shown in FIG. 7, both ends of the leaf spring 81 are connected to the support shafts 82 and 83, respectively, and the support shaft 82 is arranged on the second seat bracket 60. 83 is arranged in the back bracket 70, and the washer 84 is mounted between the leaf spring 81.

상기 각도조절레버(90)는 주지된 바와 같이 로킹부재(80)를 로킹시키거나 또는 해제시키는 것으로, 이러한 각도조절레버(90)를 해제위치로 작동시키면 판스프링(81)과 와셔(84)들이 서로 이격되어 로킹부재(80)의 로킹이 해제되기 때문에 사용자는 주지된 바와 같이 등판(20)의 각도를 적절하게 조절할 수 있으며, 한편 각도조절레버(90)를 로킹위치로 작동시키면 판스프링(81)과 와셔(84)들이 서로 밀착되어 로킹부재(80)가 로킹되기 때문에 등판(20)은 주지된 바와 같이 고정된 상태를 유지하게 된다.The angle adjusting lever 90 locks or releases the locking member 80 as is well known. When the angle adjusting lever 90 is operated to the release position, the leaf springs 81 and the washers 84 are Since the locking of the locking member 80 is spaced apart from each other, the user can properly adjust the angle of the back plate 20 as is well known, while operating the angle control lever 90 to the locking position, the leaf spring 81 ) And the washer 84 are in close contact with each other so that the locking member 80 is locked, so that the back plate 20 is kept in a fixed state as is well known.

상기 단속핀(100)은 좌판(10)의 경사각도를 단속하는 것으로, 이러한 단속핀(100)은 도 5a 내지 도 6b에서와 같이 제1좌판브래킷(40)의 핀공(41)과 안내핀공(43)에 좌우로 이동가능하게 끼워지고, 단속핀(100)의 단부에는 이탈방지용 분할핀(110)이 설치된다.The intermittent pin 100 is to interrupt the inclination angle of the seat plate 10, the intermittent pin 100 is a pin hole 41 and the guide pin hole (1) of the first seat plate bracket 40 as shown in Figure 5a to 6b ( 43) to be movable to the left and right, the separation pin 110 for preventing the separation is installed at the end of the intermittent pin 100.

이와 같이 구성된 본 고안의 전체적인 작동관계를 첨부된 도면에 따라서 상세히 설명하면 다음과 같다.When described in detail according to the accompanying drawings the overall operating relationship of the present invention is configured as follows.

먼저, 도 1에서와 같이 평상시 의자(1)의 좌판(10)과 등판(20)은 토션스프링(T1)(T2)의 탄력에 의해 대략 수평상태 및 수직상태를 탄력적으로 각각 유지하게 된다.First, as shown in FIG. 1, the seat plate 10 and the back plate 20 of the chair 1 are elastically maintained in a substantially horizontal state and a vertical state by elasticity of the torsion springs T1 and T2, respectively.

상기와 같이 상태에서 각도조절레버(90)로 로킹부재(80)를 로킹시키고 또한 도 5a,5b에서와 같이 단속핀(100)을 외측으로 당긴 상태에서, 사용자가 의자(10)에 앉아 등판(20)을 뒤로 밀면 도 5b에서와 같이 단속핀(100)이 다리브래킷(50)에 걸리지 않기 때문에, 결과적으로 좌판(10)은 도 2에서와 같이 제1축(S1)을 중심으로 A1의 경사각도만큼 뒤로 크게 회전하게 되고, 이때 상기 등판(20)은 로킹부재(80)가 로킹된 상태이므로 별도로 회전하지 않고 도 2에서와 같이 좌판(10)의 회전각도만큼 동시에 뒤로 회전하게 된다.In the above state, the locking member 80 is locked by the angle adjusting lever 90 and the state in which the intermittent pin 100 is pulled outward as shown in FIGS. 5A and 5B. 20 is pushed back so that the intermittent pin 100 is not caught by the leg bracket 50 as shown in FIG. 5B. As a result, the seat plate 10 has an inclination angle of A1 about the first axis S1 as shown in FIG. The back plate 20 is rotated as much as possible, and the back plate 20 is rotated backward by the rotation angle of the seat 10 as shown in FIG. 2 without rotating separately because the locking member 80 is locked.

다음, 각도조절레버(90)로 로킹부재(80)를 로킹시키고 또한 도 6a,6b에서와 같이 단속핀(100)을 내측으로 밀어 넣은 상태에서, 사용자가 의자(10)에 앉아 등판(20)을 뒤로 밀면 도 6b에서와 같이 단속핀(100)이 다리브래킷(50)에 걸리기 때문에, 결과적으로 좌판(10)은 도 3에서와 같이 제1축(S1)을 중심으로 A2의 경사각도만큼 뒤로 작게 회전하게 되고, 그리고 상기 등판(20)은 로킹부재(80)가 로킹된 상태이므로 별도로 회전하지 않고 도 3에서와 같이 좌판(10)의 회전각도만큼 동시에 뒤로 회전하게 된다. 이때, 상기 도 2에 도시된 A1의 경사각도는 도 3에 도시된 A2의 경사각도보다 크다.Next, in a state in which the locking member 80 is locked by the angle adjusting lever 90 and the push pin 100 is pushed inward as shown in FIGS. 6A and 6B, the user sits on the chair 10 and the back plate 20. If the back is pushed back, as shown in FIG. 6B, the intermittent pin 100 is caught by the leg bracket 50. As a result, the seat plate 10 is moved backward by the inclination angle of A2 about the first axis S1 as shown in FIG. 3. Since the back plate 20 is locked, the locking member 80 is locked and rotates backward as much as the rotation angle of the seat plate 10 as shown in FIG. At this time, the inclination angle of A1 shown in FIG. 2 is greater than the inclination angle of A2 shown in FIG. 3.

한편, 각도조절레버(90)로 로킹부재(80)의 로킹을 해제시킨 상태에서 사용자가 의자(10)에 앉아 등판(20)을 뒤로 밀면 도 4에서와 같이 좌판(10)은 제1축(S1)을 중심으로 회전하고, 또한 이와 연동하여 등판(20)은 제2축(S2)을 중심으로 회전하게 된다.On the other hand, when the user pushes the back plate 20 while sitting on the chair 10 in a state in which the locking member 80 is unlocked by the angle adjusting lever 90, the seat plate 10 is formed on the first shaft ( The back plate 20 rotates about the second axis S2 in conjunction with the rotation S1).

따라서 이러한 본 고안은 제1축(S1)과 제2축(S2)에 의해 좌판(10)과 등판(20)이 각각 회전되기 때문에 구조적으로 좌판(10)과 등판(20)의 각도조절이 한층 더 원활하고 부드럽게 이루어지는 장점이 있다.Therefore, since the seat plate 10 and the back plate 20 are respectively rotated by the first axis S1 and the second axis S2, the present invention has a further structural control of the angle of the seat plate 10 and the back plate 20. It has the advantage of being smoother and smoother.

또한 본 고안은 단속핀(100)을 통해 좌판(10)의 경사각도를 사용자가 조절할 수 있기 때문에 사용자의 편리함과 안락감을 크게 향상시킬 수 있는 장점이 있다.In addition, the present invention has an advantage of greatly improving the user's convenience and comfort because the user can adjust the inclination angle of the seat plate 10 through the intermittent pin 100.

이상에서 살펴본 바와 같이 본 고안 의자의 각도조절장치는 구조적으로 등판의 각도조절이 한층 더 원활하고 부드럽게 이루어지며, 또한 좌판의 경사각도를 조절할 수 있으므로 사용자의 편리함과 안락감을 크게 향상시킬 수 있는 매우 유용한 고안이다.As described above, the angle adjusting device of the chair of the present invention is structurally more smooth and smooth, and the angle of the back plate can be adjusted, and can also adjust the inclination angle of the seat, which is very useful for greatly improving the user's convenience and comfort. It is devised.
