A compensation system for screens of openings of windows or doors, such as for example mosquito nets and blinds, comprising at least one pleated sheet (2) inserted in a perimetral structure that can be fixed at least on two opposite sides to the opening to be screened, envisages elements for connection of the corners of the perimetral structure of the screen, i.e., for connection of the ends of the guide sectional elements (10, 18) and of the upright sectional elements (15, 17) of the structure, which are designed to provide a rigid perimetral frame constituted by said fixed upright sectional elements (15, 17) and said guide sectional elements (10, 18) within which the pleated screen (2) is stretched out or packed by displacing at least one mobile sectional element or "handle" (16); there moreover being provided a further sectional element (11), fixed to the opening in which the screen is installed, designed to co-operate with at least one of the guide sectional elements (10) - by means of a telescopic coupling in a direction substantially transverse to the guide sectional element itself - in order to compensate for the dimensional differences between said perimetral structure that contains the sheet (2) and the opening in which it is installed; wherein all the sectional elements of the structure have one and the same transverse dimension with respect to the plane of the screen itself. |
