Fastened to the circumferential surface of the rebate of the bottom-closing wing is a cover rail (7), behind which an espagnolette (8) received by a groove of the wing is guided displaceably for the purpose of actuating bolt members. Mounted pivotably on the outside of the cover rail (7) and parallel to the main plane of the latter is an operating lever (13), on which is articulated at one end a tab (17) which, via its other end, engages on the espagnolette (8) through a longitudinal slot (20) of the cover rail (7). The operating lever (13) is fastened fixedly in terms of rotation to the crank pin (14) of a crank arm (15) mounted on the outside of the cover rail (7) via a journal (16), and one end of the tab (17) is connected in an articulated manner to the crank pin (14) between the crank arm (15) and the operating lever (13). This espagnolette fastening guarantees, along with a small installation space, reliable actuation with little effort. <IMAGE> |
