Description

의자 각도조절장치용 스토퍼 연결구조{Stopper connecting structure for chair angle adjuster}Stopper connecting structure for chair angle adjuster}

본 고안은 의자의 등판각도를 조절하는 조절장치의 스토퍼를 보다 견고히 연결지지토록하는 스토퍼 연결구조에 관한 것이다.The present invention relates to a stopper connection structure to more firmly support the stopper of the adjustment device for adjusting the back angle of the chair.

의자의 각도를 조절하는 각도조절장치는 이미 여러건이 고안된바 있으며, 대부분 다리지주를 연결하는 고정프레임에 좌판을 연결고정하는 지지대가 회전가능케 연결설치되고 상기 지지대의 지지편이 각도조절레버 에 의해 회전작동하는 스토퍼의 다단 걸림편과 걸림이 이루어져 조절된 각도를 유지하도록 구성된다.The angle adjusting device for adjusting the angle of the chair has already been devised, and the support for connecting the seat plate is rotatably connected to the fixed frame connecting most leg supports, and the support piece is rotated by the angle adjusting lever. It is configured to hold the stopper with the multi-stage locking piece to maintain the adjusted angle.

상기에 있어 다리지주를 연결하는 고정프레임은 다이케스팅으로 제작되는 것으로서 스토퍼를 회전가능케 연결하는 축핀 역시 다이케스팅 제작시 본체로부터 돌출 형성하여 스토퍼의 축공을 관통하도록 구성된다.In the above, the fixing frame connecting the leg circumference is manufactured by die casting, and the shaft pin connecting the stopper so as to be rotatable is also formed to protrude from the main body during die casting to penetrate the shaft hole of the stopper.

따라서 고정프레임의 다이케스팅 제작시 스토퍼를 연결하는 축핀은 탈형을 위하여 단부로 갈수록 작은 직경으로 형성해 주어야 하므로 스토퍼의 결합시 큰 유격이 발생될 수 밖에 없어 각도조절이 정확하게 이루어 질수가 없고 각도조절후에도 좌판의 움직임각이 커 사용시 매우 불편하고 자세 불안정으로 척추에 무리를 주게된다.Therefore, the shaft pin connecting the stopper should be formed with a small diameter toward the end for demoulding when manufacturing the die casting of the fixed frame. Therefore, a large clearance can be generated when the stopper is coupled, and the angle adjustment cannot be made accurately. It is very inconvenient to use because of the large angle of movement, and it causes strain on the spine due to postural instability.

또한 축핀은 다이케스팅으로 형성될경우 강도가 매우 약함에도 불구하고 사용시 등판에 가해지는 힘은 구조적으로 축핀에 집중되므로 사용중 축핀이 쉽게 부려질 우려가 있고 축핀이 부러지게되면 축핀을 교체나 수리해줄 수가 없기 때문에 각도조절장치내지는 의자 전체를 교체해주어야 하므로 사용수명이 매우 짧고 경제적으로도 큰 손실을 가져오게 되는등의 문제점들이 있는 것이다.In addition, although the shaft pin is formed by die-casting, the strength applied to the back plate during use is concentrated on the shaft pin structurally, so the shaft pin may be easily broken during use, and if the shaft pin is broken, the shaft pin cannot be replaced or repaired. Because the angle adjusting device to replace the entire chair, there is a problem such as a very short service life and bring a large loss economically.

본 고안은 상술한 문제점들을 해결하기 위하여 축핀과 스토퍼 사이의 유격을 최소화 시켜줄수가 있고 등판에 가해지는 큰힘이 축핀에 집중되더라도 부러질 우려가 없어 축핀으로 인한 사용수명의 단축우려를 없애 줄 수가 있으며 수명이 연장되는 만큼 경제적으로도 큰 이익을 가져다 줄 수가 있는 의자 각도조절장치용 스토퍼연결구조를 제공함에 그 목적이 있다.The present invention can minimize the gap between the shaft pin and the stopper to solve the above problems, and even if the large force applied to the back plate is concentrated on the shaft pin, there is no fear of breaking it, which can eliminate the concern of shortening the service life due to the shaft pin. It is an object of the present invention to provide a stopper connection structure for the chair angle adjustment device that can bring economic benefits as well as this extension.

상기한 목적 달성을 위하여 본 고안은 고정프레임의 다이케스팅 제작시 축판이 위치하는 곳에 고정공을 형성하여 상기 고정공에 별도 제작된 축핀을 강제삽입고정하여 구성함을 특징으로 한다.In order to achieve the above object, the present invention is characterized in that a fixed hole is formed at the position where the shaft plate is located when the die casting of the fixed frame is made by forcibly inserting the shaft pin manufactured separately in the fixed hole.

도1은 본 고안의 사시도이고, 도2는 본 고안의 요부분해사시도로서, 본고안은 다리지주(2)를 연결하는 고정프레임(4)과, 고정프레임(4)의 후방에 회전가능케 연결설치되는 좌판지지대(6)와, 고정프레임(4)의 축핀(8)을 축으로 회전가능케 연결설치되며 좌판지지대(6)의 지지편(10)과 단계적인 걸림이 이루어지는 스토퍼(12)로 구성된다.Figure 1 is a perspective view of the present invention, Figure 2 is a partial exploded perspective view of the present invention, the subject is a fixed frame (4) for connecting the leg column 2, and rotatably connected to the rear of the fixed frame (4) The seat plate support 6 is to be installed, rotatably connected to the shaft pin (8) of the fixed frame (4) is composed of a stopper (12) and the support piece 10 of the seat plate support (6) is stepped. .

다리지주(2)를 연결하는 고정프레임(4)은 다이케스팅 제작되는 것으로서, 제작시 축핀(8)을 갖는 부분에 고정공(14)을 형성하여 별도로 제작된 축핀(8)을 고정공(14)에 강제삽입하여 구성하며, 상기 축핀(8)은 스토퍼(12)의 축공(16)을 관통하여 상부로 여유있게 돌출되도록 한다.Fixing frame (4) connecting the leg support (2) is produced by die casting, forming a fixed hole (14) in the portion having a shaft pin (8) when manufacturing the fixed pin (8) to the separately produced shaft pin (8) It is configured to be inserted into the, the shaft pin (8) is to pass through the shaft hole (16) of the stopper 12 to allow a protruding upwards.

스토퍼(12)는 걸림편(18)이 다단으로 형성된 걸림부(20)와, 양방향에서 스프링이 탄력지지하도록 걸림부(20)일측에 연결되며 각도조절레버(도시안됨)를 연결하는 연결대(22)로 구성된다.The stopper 12 is connected to the engaging portion 20, the engaging portion 18 is formed in multiple stages, and the engaging portion 20 to support the spring elasticity in both directions and connecting the angle adjustment lever (not shown) 22 It consists of

본 고안은 고정프레임(4)의 다이케스팅 제작후 고정공(14)에 별도제작된 축핀(8)을 강제삽입 고정한 다음 축핀(8)에 스토퍼(12)를 결합하여 축핀(8)이스토퍼(12)의 축공(16)을 관통하도록 하고, 고정프레임(4)후방에 좌판지지대(6)를 회전작동가능케 연결설치하여 지지편(10)이 스토퍼(12)의 걸림편(18)과 걸림이 이루어지도록 하므로서 각도조절장치를 구성하게 된다.According to the present invention, after the die-casting of the fixing frame 4 is made, the shaft pin 8, which is separately manufactured in the fixing hole 14, is forcibly inserted and fixed, and then the stopper 12 is coupled to the shaft pin 8 so that the shaft pin 8 is a stopper 12. And the support plate 10 is engaged with the engaging piece 18 of the stopper 12 by penetrating the shaft hole 16 of the crankshaft and connecting the seat plate support 6 so as to be rotatable. The angle adjuster is constructed by making it lose.

각도조절장치는 종래와 같이 고정프레임(4)에 다리지구(2)를 연결하고 좌판지지대(6)에 좌판을 연결해 주므로서 의자를 구성하게 된다.The angle adjusting device is configured as a chair by connecting the leg support 2 to the fixed frame 4 and the seat plate to the seat plate support 6 as in the prior art.

의자로서의 사용중 등판의 각도를 조절해 주고자 할 경우 스토퍼(12)의 긴 연결대(22)와 연결된 각도조절레버를 이용하여 스토퍼(12)를 회전시켜서 좌판지지대(6)의 지지편(16)과 걸림이 이루어져 있는 걸림편(18)이 이탈되게 하여 등판의 각도를 조정한 다음 각도조절레버를 통한 스토퍼(12)의 복귀로 조정된 지지편(10)과 같은 높낮이에 갖는 걸림편(18)과 걸림이 이루어지도록 하게 되면 등판의 각도가 조절된 상태로 고정된다.In order to adjust the angle of the back plate during use as a chair, the support piece 16 of the seat plate support 6 and the support piece 16 of the seat plate support 6 are rotated by rotating the stopper 12 using an angle adjusting lever connected to the long connecting rod 22 of the stopper 12. The locking piece 18 having the same height as the support piece 10 adjusted by the return of the stopper 12 through the angle adjusting lever by adjusting the angle of the back plate by allowing the locking piece 18 to be separated and When the locking is made, the angle of the back is fixed in a controlled state.

이때 스토퍼(12)를 연결지지하는 축핀(8)은 다이케스팅 제작되는 고정프레임의 고정공(14)에 강제삽입고정하여 구성한 것으로서, 고정프레임(4)과 별도제작되므로 전체적으로 일정한 굵기를 유지할 수가 있어 스토퍼의 결합시 유격을 최소화시켜 줄 수가 있고, 또 스토퍼를 강한 힘으로 연결지지할 수가 있어 사용중 등판으로부터 가해지는 힘이 축핀에 집중되더라도 부러질 우려가 없게 되는 것이다.At this time, the shaft pin 8 supporting the stopper 12 is configured by forcibly inserting and fixing the fixing hole 14 of the fixed frame to be manufactured by die casting, and is manufactured separately from the fixing frame 4 so that the overall thickness can be maintained. It is possible to minimize the play when combined with the stopper, and can support the stopper with a strong force so that even if the force applied from the back plate during use is concentrated on the shaft pin, there is no fear of breakage.

이와 같이 본 고안은 스토퍼(12)를 연결하는 축핀(8)을 다이케스팅 제작되는 고정프레임(4)과 별도제작하여 고정프레임(4)의 고정공(14)에 강제삽입고정하여 구성하므로서 축핀(8)을 일정한 굵기로 형성해 줄 수가 있어 스토퍼(12)의 결합시 유격의 최소화로 각도조절 후 움직임각이 거의 없어 사용시 편안하고 또 안정된 자세를 취할 수가 있으며, 등판으로부터 가해지는 힘이 집중되더라도 축핀(8)이 부러질 수 우려가 없어 축핀으로 인한 사용수명단축우려를 없애줄 수가 있는 효과를 기대할 수가 있는 것이다.As such, the present invention manufactures the shaft pin 8 connecting the stopper 12 separately from the fixed frame 4 to be manufactured by die casting, and composes and inserts the fixed pin 14 into the fixing hole 14 of the fixed frame 4, thereby forming the shaft pin 8. ) Can be formed to a certain thickness, so that when the stopper (12) is combined, there is little movement angle after adjusting the angle to minimize the play, and it is possible to take a comfortable and stable posture, and even if the force applied from the back is concentrated, the shaft pin (8) ), There is no fear of breakage, so you can expect the effect of eliminating the service life shortening caused by the shaft pin.
