Abstract: A lock for doors, windows or the like includes a case for housing a control mechanism having an electric motor for actuating at least one control rod acting upon one or a plurality of locking members. To permit the lease or unlocking of the door, window or the like in case of failure of the electric motor, the electric motor is mounted on a movable bracket which is adapted to vertically move in the case and is actuated by a drive which is controlled manually, and/or electrically and/or electromechanically.

Abstract: A fitting for doors, windows or the like, comprising locking means, in particular, a casement bolt or espagnolette lock, for locking the wing (9) against the fixed frame (11), and acting on hinged fittings consisting of a corner bearing (2) and a casement stay (3) disposed in rabbets, so that the said wing (9) can be opened at least inwardly and disposed in a ventilation position, this fitting moreover being provided with control means (21) for opening the wing (9), starting from the closed position, into the ventilation position, followed by inward opening of said wing, by acting successively on the locking means.

Abstract: This automatic double-action casement bolt comprises a pair of locking bars urged by resilient return means to a locking or bolting position in which the bars engage corresponding keepers, these bars being retracted from the keepers and moved to their unbolting position by a set of angular levers fulcrumed at their vertices on the casement bolt casing, each angular lever being connected through one arm to one of the sliding bars, each angular lever comprising, at the end of its other arm, a notch engageable by a catch of at least one control rod movable in a direction across the bars and formed integrally with an operating and control handle urged by other resilient means to its inoperative position, the notch of the other arm of each angular lever being formed in the edge of this arm so as to provide an open clearance of which the bottom constitutes a striking edge adapted, when the casement bolt is unbolted, to co-operate with the catch of the control rod.

Abstract: The invention is directed to a locking fitting, in particular for sliding casements of windows, doors or similar ports, that includes an assembly in a housing composed of a slide connected to a bolt for the purpose of locking the bolt in position and a locking device fitted with a pawl featuring at least one tooth and actuated by a grip integral with the slide and by a for controlling the locking device featuring a no-load run of the slide prior to moving the bolt.This locking fitting is characterized in that it comprises a blocking device with resilient pull-back that locks the bolt in its open position which is integral with the slide in shifting.

Abstract: This fitting for two-way opening windows or French-windows is adapted to be operated by means of a single handle for imparting to the fitting a locked position and two opening positions; the fitting is disposed between the fixed frame and the movable frame of the window and comprises on the one hand at least one locking member rigid with a control rod disposed on one of the frames and adapted to be moved through a distance corresponding to two successive pitches by actuating the handle, and on the other hand at least one keeper engageable by the locking member and disposed on the other frame, this keeper comprising locking means of which one component, the locking member or the keeper, is movable through a distance corresponding to one pitch of the movement performed by the control rod in the direction of travel thereof.
