What is described is a rebate mechanism for the overlapped wing of two-wing windows or doors without fixing timber, which rebate mechanism comprises two oppositely adjustable coupling pins each guided in a long hole of a stop plate and each intended for an espagnolette, as well as a one-armed actuating lever, the rotary axle of which extends perpendicular to the stop plate. To achieve a flat design which can be obtained at low outlay in terms of construction, the rotary axle of the actuating lever is connected to one coupling pin, and there engages on the other coupling pin a link which is articulated on the actuating lever at a distance from the rotary axle of the latter. |
