The innovation introduced is a novel type of window and window-door hardware that provides an alternative to the traditional tilt andturn system of casement windows, aiming to overcome its limitations. The key advancement lies in the use of the same hinges forboth casement and restricted opening modes. This brings a significant improvement in terms of security by eliminating the risk ofdetachment between the pins and their respective seats during restricted opening. This innovation allows for a combination of thegenerous air circulation provided by casement opening with the security and limited passage typical of top-hung opening.Furthermore, the new hardware greatly simplifies the movement of the panels, enabling easy opening and closing even for heavypanels. This represents a notable progress compared to conventional solutions that require considerable effort to lift and close largepanels. The operation with the new hardware system is carried out using a handle, which, when perpendicular to the jamb, allows fora classic casement opening. When in a parallel position to the jamb, rotated upwards, and then returned to the closed position, itenables the locking of the panel, which remains open as a casement for only a space of 5/10 cm. This innovative window and doorhardware not only addresses the safety concerns associated with traditional systems but also enhances user convenience and easeof operation, particularly with large and heavy panels.
