Description

연결식 의자의 회전 제어장치{device for control rotation of coupling chairs}Device for control rotation of coupling chairs

본 고안은 연결식 의자에 관한 것으로, 특히 코일스프링을 가압하면서 수평방향으로 회전된 받침프레임에 가압력이 해제되면, 코일스프링의 복원력으로 받침프레임이 원래의 상태인 수직방향으로 복원할 때, 받침프레임의 회전속도를 조절하여 안정감있게 복원시키는 연결식 의자의 회전 제어장치에 관한 것이다.The present invention relates to a connected chair, in particular, when the pressing force is released to the support frame rotated in the horizontal direction while pressing the coil spring, when the support frame is restored to its original state in the vertical direction by the restoring force of the coil spring, The present invention relates to a rotation control device of a connected chair that restores stability by adjusting the rotation speed.

주지된 바와 같이 철재 연결식 의자는, 많은 인원이 편안하게 앉아 영화를 관람하거나 교육 및 회의 등을 할 수 있도록 극장, 회의실 등에 여러 개의 의자가 횡렬로 연결되어 설치되며, 사용자가 연결식 의자의 받침프레임에 앉고, 일어설 때, 코일스프링의 복원력으로 받침프레임이 순간적으로 회전하면서 복원되나, 이때, 코일스프링의 복원력이 강해 받침프레임의 단부가 연결식 의자의 내부와 충돌하여 소음을 발생시키는 문제점이 있었다.As is well known, the steel chair is installed in a row with several chairs in a theater, a meeting room, and the like so that a large number of people can sit comfortably to watch a movie or to have an education and a meeting. When sitting and standing up, the support frame is instantaneously rotated by the restoring force of the coil spring, but at this time, the restoring force of the coil spring is strong so that the end of the support frame collides with the inside of the connected chair to generate noise.

상기와 같은 문제점을 해결하기 위해 본건 출원인은 2003년 특허 제60298호로 출원하여 2003년 제78823호로 공개된 연결식 의자의 완충장치를 사용하였다.In order to solve the above problems, the present applicant used the shock absorber of the connected chair, which was filed in 2003 60298 and filed in 2003 78823.

선 공개된 연결식 의자의 완충장치는, 도 1에 도시된 바와 같이, 사용자가받침프레임(15)을 전방으로 회전시키면, 회동축(154)에 감겨진 코일스프링(155)에서 반발력이 발생함과 동시에 작동부재(220)의 마찰편(226)이 회동축(154)을 중심으로 회전함에 따라 덮개(230)의 내부에서 유압오일(240)을 이동시키므로 수평상태로 회전된 받침프레임(15)에 안착할 수 있다.As shown in FIG. 1, when the user rotates the support frame 15 forward, a repulsive force is generated in the coil spring 155 wound around the rotation shaft 154. At the same time, as the friction piece 226 of the operating member 220 rotates about the rotation shaft 154, the hydraulic oil 240 is moved inside the cover 230 so that the supporting frame 15 rotated in a horizontal state. I can rest.

한편, 사용자가 일어나 받침프레임(15)에 가해진 가압력을 해제시키면, 코일스프링(155)의 복원력에 의해 받침프레임(15)이 회동축(154)을 중심으로 상부로 회전함과 동시에 작동부재(220)도 같이 회전하게 되는데, 이때, 상기 작동부재(220)의 마찰편(226)이 회동축(154)과 같이 회전하면서 유압오일(240)에서 저항을 발생시킴에 따라 스토퍼축(156)이 분리판(13)의 안내공간에 서서히 밀착하기 때문에 소음을 발생하지 않으면서 받침프레임(15)을 수직상태로 유지할 수 있는 것이다.On the other hand, when the user wakes up and releases the pressing force applied to the support frame 15, the support frame 15 is rotated upwardly about the pivot shaft 154 by the restoring force of the coil spring 155 and at the same time operating member 220 ) Also rotates together, whereby the stopper shaft 156 is separated as the friction piece 226 of the operating member 220 generates resistance in the hydraulic oil 240 while rotating together with the rotation shaft 154. Since it is in close contact with the guide space of the plate 13 will be able to maintain the support frame 15 in a vertical state without generating noise.

그런데 상기와 같이 선 공개된 연결식 의자의 완충장치는, 종래의 문제점을 해결하는 이점은 있으나, 덮개의 내부에 위치한 유압오일이 온도변화에 따라 점성차가 다르고, 점성차에 따라 받침프레임의 회전속도가 불균형하여 제품에 대한 신뢰성을 저하시키는 문제점이 있었다.By the way, the shock absorber of the connected chair is disclosed as described above, there is an advantage to solve the conventional problems, the hydraulic oil located inside the cover is different in viscosity according to the temperature change, the rotational speed of the support frame according to the viscosity difference There was a problem of unbalance to lower the reliability of the product.

또한, 유압오일이 저장된 덮개에서 누수가 발생하게 되면, 누수된 유압오일만큼 덮개의 내부에 저장된 유압오일의 양이 감소됨에 따라 받침프레임의 회전속도가 증가하여 스토퍼축에 부딪혀 소음을 발생시킴과 아울러 유압오일의 보충이 어려워 완충부를 교환.설치해야 하는 작업공정이 번거로울 뿐만 아니라 제품의 유지관리가 어려운 문제점이 있었다.In addition, when a leak occurs in the cover in which the hydraulic oil is stored, as the amount of the hydraulic oil stored in the cover is reduced by the leaked hydraulic oil, the rotational speed of the support frame increases to generate noise by hitting the stopper shaft. Difficult to replenish hydraulic oil, so the work process that needs to be replaced and installed is not only cumbersome, but also difficult to maintain the product.

이에 본 고안은 상술한 바와 같은 종래의 제반 결함을 감안하여 이루어진 것으로, 그 목적은 수평으로 회전된 받침프레임을 항상 일정한 속도로 복원될 수 있도록 제어하여 제품에 대한 신뢰성을 향상시킴과 아울러 구조가 간소화되어 작업시간을 단축시킴과 동시에 제품의 유지관리를 용이하게 하는 연결식 의자의 회전 제어장치를 제공함에 있다.The present invention has been made in view of the above-mentioned conventional defects, and its object is to control the horizontally rotated support frame to be restored at a constant speed at all times, thereby improving reliability of the product and simplifying the structure. In order to reduce the working time and at the same time to facilitate the maintenance of the product is to provide a rotation control device of the connected chair.

이러한 목적을 달성하기 위한 본 고안은, 연결식 의자에 있어서,The present invention for achieving this object, in the linked chair,

수평방향으로 회전된 받침프레임을 항상 일정한 속도로 복원시켜 수직방향을 유지하도록 회동축에 장착되어 제어하는 회전제어부가 구성되는 것을 특징으로 하는 것이다.It is characterized in that the rotation control unit is mounted on the rotating shaft to control the support frame rotated in the horizontal direction to maintain a vertical direction at all times to restore at a constant speed.

다음은 상기와 같이 구성된 본 고안의 조립과정 및 작동과정을 설명한다.The following describes the assembly process and operation process of the present invention configured as described above.

먼저, 지지부재(310)의 고정공(312)에서 고정부재(320)가 이탈하지 않도록 체결하고, 상기 지지부재(310)의 회전지지공(315)에 가스쇼바(330)의 결합돌기(331a)를 회전가능하게 결합하며, 상기 가스쇼바(330)의 고정공(332a)에 복원스프링(340)을 장착하여 회전제어부(300)의 결합을 완료한다.First, the fixing member 320 is fastened so that the fixing member 320 is not separated from the fixing hole 312 of the supporting member 310, and the coupling protrusion 331a of the gas shobar 330 is connected to the rotating supporting hole 315 of the supporting member 310. ) Is rotatably coupled, and the restoration spring 340 is mounted in the fixing hole 332a of the gas showbar 330 to complete the coupling of the rotation control unit 300.

상기와 같이 결합된 회전제어부(300)를 받침프레임(15)의 저면에 위치시킨 상태에서 받침프레임(15)의 내측으로 이동되는 회동축(154)에 지지부재(310)의 지지편(313)을 밀착시키면, 상기 지지편(313)의 안내공(314) 내측으로 회동축(154)이 이동하면서 안내공(314)에 결합된다.The support piece 313 of the support member 310 on the pivot shaft 154 which is moved to the inside of the support frame 15 in a state where the combined rotation control unit 300 is located on the bottom of the support frame 15 as described above. In close contact with the guide shaft 154, the pivot shaft 154 moves inside the guide hole 314 of the support piece 313 and is coupled to the guide hole 314.

한편, 상기와 같이 회동축(154)에 회전제어부(300)가 결합되면, 상기 회동축(154)의 일측에 회전제어부(300)를 위치시킨 상태에서 고정공(312)에 고정된 고정부재(320)를 체결하여 회동축(154)의 단부를 가압하면서 견고하게 고정되며, 상기 복원스프링(340)을 받침프레임(15)의 내측면에 고정시키면 된다.On the other hand, when the rotation control unit 300 is coupled to the rotation shaft 154 as described above, the fixing member fixed to the fixing hole 312 in a state in which the rotation control unit 300 is located on one side of the rotation shaft 154 ( The fastening 320 is firmly fixed while pressing the end of the rotation shaft 154, and the restoring spring 340 may be fixed to the inner surface of the support frame 15.

다음은 상기와 같이 고정된 받침프레임(15)에 사용자가 착석하기 위해 받침프레임(15)을 전방으로 회전시키면, 도 4a에 도시된 바와 같이 상기 받침프레임(15)은 회동축(154)을 중심으로 전방으로 회전함과 동시에 상기 회동축(154)에 결합된 회전제어부(300)의 지지부재(310)가 상기 회동축(154)과 같이 전방으로 회전하게 된다.Next, when the user rotates the support frame 15 forward to seat the fixed support frame 15 as described above, the support frame 15 is centered on the pivot shaft 154 as shown in Figure 4a At the same time, the support member 310 of the rotation control unit 300 coupled to the rotation shaft 154 is rotated forward as the rotation shaft 154 at the same time.

이때, 상기 지지부재(310)의 회전지지공(315)에 결합된 가스쇼바(330)의 하우징(331)은 결합돌기(331a)를 중심으로 회전함과 동시에 상기 하우징(331)의 내면을 따라 일측단부에서 타측단부로 이동하며, 이동되는 작동봉(332)에 의해 하우징(331)의 내부에 위치한 가스를 일측공간에서 타측공간으로 이동시키면서 이동하고, 상기 작동봉(332)의 단부가 하우징(331) 내부의 타측단부에 밀착하면, 상기 작동봉(332)의 고정공(332a)에 결합된 복원스프링(340)을 당기면서 회전되며, 상기 회동축(154)을 따라 회전되는 가스쇼바(330)와 복원스프링(340)은 일직 선상을 유지하면서 탄력있게 지지하게 된다.At this time, the housing 331 of the gas shobar 330 coupled to the rotary support hole 315 of the support member 310 rotates around the coupling protrusion 331a and along the inner surface of the housing 331. Moving from one end to the other end, the gas located inside the housing 331 by the operating rod 332 is moved while moving from one side space to the other space, the end of the operating rod 332 is the housing ( 331 is in close contact with the other end of the inside, is rotated while pulling the restoring spring 340 coupled to the fixing hole 332a of the operating rod 332, the gas shoba 330 rotated along the rotation shaft 154 ) And the restoring spring 340 is elastically supported while maintaining a straight line.

또한, 상기 받침프레임(15)과 같이 회전되는 스토퍼축(156)이 분리판(13)의 안내공간 상단부에 밀착하게 되면 상기 받침프레임(15)의 회전동작을 정지시킴과동시에 받침프레임(15)은 수평상태로 회전된다.In addition, when the stopper shaft 156 rotated together with the support frame 15 comes into close contact with the upper end of the guide space of the separating plate 13, the rotation operation of the support frame 15 is stopped and at the same time the support frame 15 is supported. Is rotated horizontally.

상기 수평상태로 회전된 받침프레임(15)에 사용자가 앉게 되면, 사용자가 받침프레임(15)에 가해지는 압력이 회전제어부(300)의 복원력보다 크게 작용하여 상기 받침프레임(15)은 수평을 유지함과 동시에 연결식 의자가 설치된 장소에 따라 강의를 듣거나, 회의 및 영화관람 등등을 할 수 있는 것이다.When the user sits on the support frame 15 rotated in the horizontal state, the pressure applied to the support frame 15 is greater than the restoring force of the rotation control unit 300 to maintain the support frame 15 is horizontal. At the same time, depending on where the connected chair is installed, you can listen to lectures, conferences, and watch movies.
