SCREENING DEVICE Russian patent published in 2014 - IPC E06B9/02 

FIELD: construction.

SUBSTANCE: invention relates to shielding and protective devices for apertures. Screening device is designed so that the size of the first rigid links (24), which form the upper part of the guide frame (15) is smaller than the size of the second rigid links (17), which form the lower part of the guide frame (16). And when the upper part of the guide frame and lower part of the guide frame are hidden inside the mounting frame (10) of the screen, the portions of the side walls (18) of the first rigid links are adjacent from the inner side between the portions of the side walls of the second rigid links. In this case the upper part of the guide frame crosses the lower part of the guide frame inside the mounting frame of the screen. Connection of the first rigid links can be disconnected in any position inside the mounting frame of the screen when adjusting the length of the screening device (1), and the upper portion of the guide frame can be removed from the mounting frame of the screen, thus simplifying the adjustment of length in the place of installation.

EFFECT: invention allows the easy adjustment of length of the screening device.
