FIELD: construction.
SUBSTANCE: dual pane window contains two window panes parallel to each other and supported by the metal frame, installed between the window panes. The frame and the window panes form a chamber, a curtain/tent, located in said chamber, a group for movement of said curtain/tent, and a device for controlling the actuation of said group for movement. Said device contains a roller, performed with ability to rotate about its own axis, roller support facilities, connected to said group for moving and performed with ability to rotate the roller, a cord ring at least partially wound around the roller and containing two sections of the cord, extending from the roller in the same direction in diametrically opposite positions, relative to the roller. When tension is applied to the cord ring, the torque, that approaches to turn the roller, occurs. The torque with the help of the transfer facilities is transferred to the group for moving the curtain/tent. The supporting facilities are separated from said group for transferring by one of the window glasses of said dual pane window, connected to the connecting element, which is the integral part of said dual pane window wall, providing support for the roller at the tension value, applied to at least one of said cord sections, smaller than the predetermined value, and are performed with ability to detach the said supporting facilities from the mentioned group for moving, when exceeding the specified value.
EFFECT: curtain activation safety in the dual pane window.
