Automatic opening and closing mechanism for sliding windows such as door wings.

摘要

The present invention relates to automatic opening and closing mechanisms for the sliding wings of windows or doors. The mechanism in question, located above the frame holding the sliding wings, is completely independent of the functions of supporting and guiding said wings. It comprises a drive means (13) driven in a horizontal to-and-fro movement, making the connection between the wing to be driven (2) and the drive mechanism (10) by way of a slot (14) made longitudinally in the horizontal upper part (8) of the fixed basic frame.
