Abstract
The invention concerns a closing system for doors and/or windows. The system comprises a first male element (20), also commonly called “quadrello” in Italian, intended to move a bolt by rotating it, and a second female element (10) suited to be operated in such a way as to set the male element or “quadrello” (20) rotating. The male element and the female element (20, 10) are suited, when in use and/or when applied, for example, to a door and/or window, to be mutually fixed in a configuration of use, wherein in the configuration of use or operation an end portion of the male element (20) is housed in a first corresponding seat (14) created in the female element (10). The system comprises a closing element (12) suited to mutually lock the male and female elements (20, 10) in the configuration of use or operation. The closing element (12) is housed in a second corresponding seat (11) created in the female element (10) and is configured in such a way that it can be switched in a locked position in which it is engaged with the male element or “quadrello” (20) through the insertion of the end portion of the male element or “quadrello” (20) in the first corresponding seat (14) created in the female element (10).
