Abstract

본 발명은 간편한 유, 무선조작에 의해 스크린이 하부에서 상부로 직립 승, 하강 설치되도록 하여 스크린을 장소에 구애받음 없이 간편하게 사용할수 있게 하는 동시에 직립설치된 상태에서도 스크린면을 항상 팽팽한 상태로 유지할수 있게 함으로써 투영되는 상의 왜곡현상을 방지할수 있게한 직립 승, 하강식 스크린장치로서, 스크린(1), 이 스크린(1)을 지지하는 스크린 지지장치(2), 이 스크린 지지장치(2)를 승, 하강시키는 스크린 승, 하강장치(3), 스크린(1)이 펼쳐지거나 감겼을 때 스크린(1)에 긴장사태를 부여하는 스크린 텐션장치(4), 스크린(1)이 직립 설치된 상태에서 전방으로의 기울어지는정도를 조절하기 위한 경사조절장치(5) 및 상기 장치들이 설치되는 베이스(6)로 구성되어 있다.The present invention allows the screen to be installed up and down from the bottom to the top by simple wired and wireless operation so that the screen can be used easily regardless of the place, and at the same time, the screen surface can be kept always taut even in an upright installation state. The upright lifting and lowering screen device which prevents the distortion of the projected image by preventing the screen 1, the screen support device 2 supporting the screen 1, and the screen support device 2 are raised and lowered. When the screen is lifted, lowered (3), the screen (1) is unfolded or wound, the screen tensioning device (4) and the screen (1), which impart tension to the screen (1), are inclined forward. It is composed of a tilt control device 5 for adjusting the degree of losing and the base 6 on which the devices are installed.
