Attaching mosquito net to window frame - involves auxiliary frame equipped with clamping screws

摘要

The mosquito net for covering an open window is attached first to a rectangular frame (3) so that it is held at the required tension. The frame is made of wood fastened together with corner elements. Each corner element is provided with a clamping screw which can be screwed outwards at an angle of 45 deg to the adjacent sides. The frame with the attached net is placed in the window frame and the clamping screws are rotated so that the tip of each screw engages an internal corner of the window frame and clamps the mosquito net frame to the window frame. A sheet of plastics film (2) may be held in the window frame in a similar way. USE/ADVANTAGE - The window frame is undamaged by the fixing of the mosquito net.
