Abstract
A method for mounting an auxiliary member on a window or door frame already installed and whereon is mounted a drive assembly comprising at least one actuating member and at least one transmission rod mounted in at least one slot of the frame. The method comprises the steps of, providing, between the auxiliary member and the rod, a coupling that is slidable in a longitudinal direction and fixed in any direction orthogonal to the direction of sliding, and forming a through hole in the rod by a screw carried by the auxiliary member, and fastening the auxiliary member to the rod by the engagement of a tip of the screw with the through hole.

A method for mounting an auxiliary member on a window or door frame and whereon is mounted a drive assembly comprising an actuating member and a transmission rod mounted in a slot of the frame, the method comprising:
- slidably engaging the auxiliary member with the transmission rod, wherein the auxiliary member includes a threaded hole with a screw in a partially screwed position;
- and
- completely tightening said screw in the threaded hole of the auxiliary member thereby forming a non-threaded through hole with a smooth lateral wall in the transmission rod by a non-threaded tip of the screw which shears a base portion of the transmission rod as a result of screwing a threaded body of the screw in the threaded hole provided in the auxiliary member and fastening the auxiliary member to said transmission rod by the engagement of the non-threaded tip of said screw with said non-threaded through hole, wherein the non-threaded tip of said screw is a cylindrical body with a constant diameter
- wherein:
- said transmission rod comprises a central portion and two lateral portions forming respective channel-shaped guides situated at opposite ends relative to the central portion, the central portion having two lateral extensions having inclined lower surfaces,
- said auxiliary member having a coupling portion comprising a body and two parallel longitudinal ribs projecting from the body, the longitudinal ribs having respective ends shaped so as to establish a sliding coupling in said channel-shaped guides, said ends of the longitudinal ribs having respective inner lateral extensions having inclined upper surfaces which contact said inclined lower surfaces when said screw is tightened for forming said non-threaded hole.
