  The present invention relates to a window frame incorporating a projection screen.

  In recent years, it has become increasingly popular to enjoy movies on a large projection screen at home. Large projection screens come in from 50 inches diagonal to over 100 inches diagonal.

  As a method of installing the projection screen, there is a method of hanging from the ceiling. At this time, if the upper end portion of the image is projected near the ceiling, the viewer will appreciate the image looking up from below, which is not suitable for long-time viewing. For this reason, the screen was enlarged in the lower direction and the projection position was lowered. However, this made the projection screen larger and heavier.

  Another method for installing a projection screen is to place a hanging tool on the floor and suspend the screen from the hanging tool. At this time, it is no longer necessary to unnecessarily enlarge the screen by setting the upper end position of the hanging tool to an appropriate position. However, it was troublesome to install and clean up the screen.

  Further, in a projection type projector such as a liquid crystal projector or an overhead projector, it is necessary to darken a room in order to view a contrasting image in the daytime. For this reason, it is important to shield the room, and a thick curtain or the like is hung from the window.

  In addition, the projection screen that receives light from the projector needs to have flatness, but if the projection screen surface is wrinkled or sagging, the projected image will appear as distortion in the wrinkled or sagging portion, which is problematic for viewing. was there.

On the other hand, there is (Patent No. 353280) as a window screen device. In the case of this proposal, a screen device that slides in parallel with a window shoji, and as a projection screen for projecting a 16: 9 movie or the like, the horizontal drawer of the screen is difficult to achieve flatness of the screen surface. It was not.
