본 고안은 의자등판의 등판부재 가변장치에 관한 것으로, 더욱 구체적으로는 등판을 구성하는 등판부재가 다단으로 설치되어 전ㆍ후면을 변환시켜 사용할수 있도록 되어 있는 등판부재의 가변장치 구성이 간단하고 안정된 가변상태를 유지할수 있도록 한 것이다.The present invention relates to a back member variable device of a chair back. More specifically, the back member of the back member is installed in multiple stages, and thus the back member can be used to convert the front and rear sides. It is to maintain the variable state.
일반적으로 의자의 등판 및 좌판이 합성수지, 금속, 목재로 구성되어 받쳐주도록 되어 있는 것은 안락감이 떨어지므로 주로 간이의자로 이용되고 있으며, 평상시에 앉아서 장기간 업무를 보게되는 사무용의자는 의자의 등판및 좌판을 쿠션재를 가죽시트나 직물시트로 감싼형태로 되어 안락감을 주도록 되어 있다.In general, the back and seat of the chair are made of synthetic resin, metal, and wood to support them, so they are often used as simple chairs because they are less comfortable. The cushion material is wrapped in leather seat or fabric seat to give comfort.
이러한 종래의 사무용의자의 등판은 단일판체로 구성되어 체대에 일체로 고정된 형태로 되어 있는바, 이는 공기소통이 좋지 않게 되어 온도가 높은 여름철에는 땀이 많이 배게되고 더위에 취약할 뿐만 아니라 목이나 허리를 받쳐주기 위한 목받침이나 허리받침을 별도로 구비해야 되는 등의 문제점이 있었다.The back of such a conventional office chair is composed of a single plate body and is integrally fixed to the body bar. This means that air communication is poor, so that in the summer when the temperature is high, the sweat is soaked and heat is vulnerable. There was a problem such as having to provide a separate neck support or waist support to support the waist.
또한, 등판의 표면시트부분이 항상 가죽시트 또는 직물시트와 같이 어느하나로 되어 있는 정형화된 의자로 되어 있기 때문에 계절적인 특성이나 접촉감, 개인적인 취향에 맞출수 없었다.In addition, since the surface seat portion of the back is always a formal chair made of either leather seat or fabric seat, it could not be adapted to seasonal characteristics, touch feeling, or personal taste.
이를 감안하여 본 출원인에 의해 실용신안등록제20-0355157호로 등록된 사무용 의자등판은 등판을 구성하는 다단의 등판부재에 의해 공기소통이 원활하고 등판의 전ㆍ후면을 변환시킬수 있는 가변장치가 구성되어 편리하게 사용할수 있게 되었는바, 본 고안은 상기 가변장치의 또다른 구성실시예를 제공함에 있다.In consideration of this, the office chair backboard registered by the present applicant as Utility Model Registration No. 20-0355157 has a variable device capable of smoothly communicating with air and converting the front and back of the backplate by a multi-stage backplate member constituting the backplate.
