Abstract

The present invention relates to a grandstand chair having a seat rotation delay function and, more particularly, to a grandstand chair having a seat rotation delay function that eliminates the need for a seated person to rotate a folding seat for re-seating after temporarily standing up. The grandstand chair having a seat rotation delay function of the present invention can delay the rotation of a seat part in the direction parallel to a backrest when the seated person temporarily stands up such that convenience is improved because there is no need for a separate operation of the seat part when the seated person re-sits on the seat part.

본 발명은 좌석부 회동 지연기능이 있는 관람석 의자에 관한 것으로서, 더욱 상세하게는 착석자가 일시적으로 기립 후 재 착석을 위해 폴딩되는 좌석부를 회동시킬 필요가 없는 좌석부 회동 지연기능이 있는 관람석의자에 관한 것이다.The present invention relates to a spectator chair having a seat rotation delay function, and more particularly, to a spectator chair having a seat rotation delay function that does not require a seated member to temporarily rotate a folding seat for re-seating after standing up. will be.
일반적으로 각종 경기장, 영화관 등 다중 이용시설에는 관람을 위한 의자, 즉, 관람석 의자를 설치하고 있는데, 이를 설치함에 있어서 공간의 효율적 활용을 위해 계단식 콘크리트 구조물을 설치한 후, 상기 콘크리트 구조물의 경사면, 벽체 또는 수평면(바닥면)에 관람석 의자를 설치하게 된다. In general, multi-use facilities such as various stadiums and movie theaters are equipped with chairs for viewing, that is, grandstand chairs. Alternatively, a grandstand chair will be installed on a horizontal surface (floor surface).
이러한 관람석 의자는 국내 실용신안공보 제20-1993-0003026호에 개시된 바와 같이 사람이 지나다니기 용이하게 이동공간이 마련될 수 있도록 좌석부재가 등받이 부재 측으로 접철되는 접철식 의자가 주로 사용된다. 종래의 관람석 의자는 좌석부재의 한쪽에 고정 브라켓을 나사를 이용하여 고정설치한 다음 프레임에 이대로 형성된 고정축에 삽입하고, 프레임의 다른 쪽에는 고정브라켓을 삽입한 다음 고정브라켓의 착석부 제철부에 착석부을대고 나사로 브라켓과 고정하여 조립하였다.As disclosed in Korean Utility Model Publication No. 20-1993-0003026, a folding chair in which the seat member is folded toward the backrest member is mainly used as such a grand chair. In the conventional grandstand chair, a fixing bracket is fixedly installed on one side of the seat member using a screw, and then inserted into the fixed shaft formed as it is in the frame, and the fixing bracket is inserted into the other side of the frame, and then the seat part of the fixing bracket is made of iron. It was assembled by attaching the seating part to the bracket and fixing it with screws.
이러한 관람석 의자는 좌석부재의 회전축에 토션 스프링을 설치하여 토션 스프링의 탄성력에 의해 좌석부재가 자동으로 회동되도록 한다.Such a grandstand chair installs a torsion spring on the rotation shaft of the seat member so that the seat member automatically rotates by the elastic force of the torsion spring.
그러나 상기 관람석 의자는 토션스프링의 탄성력에 의해 좌석부재가 회동시 등받이 부재에 충돌하여 타인의 관람을 방해하는 소음이 발생하거나 충돌로 인한 충격을 인해 좌석부재 및 등받이 부재가 파손되는 단점이 있었고, 경기장에 많은 사람이 유입되어 무질서한 상황에서 좌석부재의 빠른 회전에 의해 안전사고 및 인사 사고가 발생될 수 있는 문제점이 있었다.However, in the grandstand chair, the seat member collides with the backrest member when the seat member rotates due to the elastic force of the torsion spring, thereby generating noise that interferes with the viewing of others, or the seat member and the backrest member are damaged due to the impact caused by the collision. There was a problem that safety accidents and personnel accidents could occur due to the rapid rotation of the seat member in a disorderly situation due to the influx of many people.
상기와 같은 관람석 의자의 단점을 극복하고자 국내 공개특허공보 제10-2015-0072557호에는 "회전의자용 댐퍼"가 제안된 바 있다. 하지만, 상기의 회전의자용 댐퍼는 탄성력에 의해 좌석부재를 회동시키기 위한 토션스프링이 내장된 설치공간에 소정의 점성을 갖는 실리콘 오일과 같은 충진액을 충진하여 토션스프링에 마찰력을 제공함으로써 좌석부재의 회동속도를 감속시키는 방식으로 충진액의 누수 가능성이 존재하고, 그로 인해 장기간 충분한 댐핑력을 유지하는 데에는 한계가 있었고, 프레임에 대해 좌석부재를 비스듬하게 설치할 수 없어 원형 관람석에는 설치가 불가능한 단점이 있었다.In order to overcome the disadvantages of the grandstand chair as described above, "a damper for a swivel chair" has been proposed in Korean Patent Publication No. 10-2015-0072557. However, the damper for the swivel chair is filled with a filling liquid such as silicone oil having a predetermined viscosity in an installation space in which a torsion spring for rotating the seat member by elastic force is provided to provide friction to the seat member. There is a possibility of leakage of the filling fluid by reducing the rotational speed, so there is a limit to maintaining sufficient damping force for a long time. .
이러한 문제점을 개선하고자 본 출원인은 대한민국 등록특허공보 제10-1688174호에 게시된 마찰 댐핑부가 구비된 폴딩의자와, 제10-2019-0139543호에 게시된 댐핑기능이 있는 관람용 폴딩의자를 개발한 바 있다. In order to improve this problem, the present applicant has developed a folding chair with a friction damping part disclosed in Korean Patent Publication No. 10-1688174 and a folding chair for viewing with a damping function published in No. 10-2019-0139543. there is a bar

회동지연부(200)는 도시된 바와 다르게, 제1회동지연부(202)와 제2회동지연부(204) 중 어느 하나만 구비될 수도 있다. 제 1 및 제2회동지연턱(202,204)은 고정브라켓(50)에 일체로 형성될 수 있으며, 분리가능한 구조로 결합될 수도 있다. The rotation delay unit 200 may be provided with either one of the first rotation delay unit 202 and the second rotation delay unit 204 differently from the illustration. The first and second rotation delay projections 202 and 204 may be integrally formed with the fixing bracket 50 and may be coupled to each other in a separable structure.
또는, 회동지연부는 다른 실시 예로서, 도 5에 도시된 바와 같이, 고정브라켓(50) 측에 회동가이드홈(55)의 길이방향 일측에 돌출되게 장착되어 스토퍼돌기(86)가 간섭되는 회동지연핀(206)을 구비할 수 있다. 이 경우, 회전브라켓(60)은 회동지연핀(206)에 스토퍼돌기(86)가 간섭되어 회동이 일시적으로 제한될 수 있다. Alternatively, as another embodiment, as shown in FIG. 5, the rotation delay unit is mounted to protrude one side of the rotation guide groove 55 in the longitudinal direction on the side of the fixing bracket 50 and the stopper projection 86 interferes with the rotation delay. A pin 206 may be provided. In this case, the rotation bracket 60 may be temporarily limited in rotation by the stopper protrusion 86 interfering with the rotation delay pin 206 .
또는, 스토퍼돌기(86)는 원통 형상으로 형성되어 있으나, 도시된 바와 다르게 양측면이 제1 및 제2회동지연턱(202,204)의 연장방향에 나란하게 호형곡률을 갖도록 형성되어 제1 및 제2회동지연턱(202,204)과 접촉면적이 보다 넓게 확보될 수도 있다.Alternatively, the stopper protrusion 86 is formed in a cylindrical shape, but differently from the drawings, both sides are formed to have arc-shaped curvature in parallel in the extending direction of the first and second rotation delay projections 202 and 204, so that the first and second rotation A larger contact area with the delay jaws 202 and 204 may be secured.
본 발명의 일 실시 예에 따른 좌석부 회동지연기능이 있는 관람석은 일시적으로 착석자가 기립 시 등받이와 나란한 방향으로 착석부의 회동을 지연시킬 수 가 있어, 착석자가 착석부에 재착석 시 별도의 착석부 조작이 필요 없어 편의성이 향상되는 이점이 있다. In the grandstand having the seat rotation delay function according to an embodiment of the present invention, it is possible to temporarily delay the rotation of the seating part in the direction parallel to the back when the occupant stands up. There is an advantage in that convenience is improved as no operation is required.
