An espagnolette fastening for the fitting-under wing of two-wing windows or doors without mullions - a so-called lap-closing wing fastening - is to acquire a design which, with a small installation space, guarantees a reliable actuation with little effort. Fastened to the circumferential face of the rebate of the fitting-under wing is a slip-over rail (7), behind which an espagnolette (8) received by a groove of the wing is guided displaceably for the purpose of actuating bolt members. Pivotably mounted parallel to the main plane of the slip-over rail (7) on the outside of the latter is an operating lever (13), on which is articulated (14) at one end a tab (17) which engages via its other end on the espagnolette (8) through a longitudinal slot (20) of the slip-over 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 slip-over rail (7) via a journal (16), and one end of the tab (17) is in articulated connection with the crank pin (14), between the crank arm (15) and the operating lever (13). <IMAGE> |
