A hinge for a panel or window has a frame subassembly having a frame leaf mountable on a fixed frame and a substantially cylindrical bushing fixed to the leaf and centered on an axis, a panel subassembly having a leaf mountable on the panel of the door and a flange fixed to the leaf, and a hinge-pin assembly pivotally interconnecting the frame and panel subassemblies and having a hinge pin rotatable in the bushing and a part fixed to an end of the hinge pin and having a seat slidably receiving the flange. An adjuster moves the flange in the seat in the hinge-pin subassembly in a transverse direction normal to the axis of the hinge-pin subassembly. A clamping block is slidable in the transverse direction in the part of the hinge-pin assembly. A connecting element secures the clamping block to the hinge-pin subassembly and can slide in the flange.

Hinge for door or window

In a lock of a door or a window with a basic lock and at least an auxiliary locking device and at least a first actuation arrangement for locking the lock, a second actuation arrangement separate from the first actuation arrangement is provided for unlocking the lock.

Lock

A door lock has a housing adapted to be mounted on an edge of the door, inside and outside nuts rotatable about respective inside and outside axes on the housing, and respective inside and outside handles fixed to the nuts and respectively projecting inward and outward from the door with each handle movable upward and downward from a central position. A pair of bolts in the housing each movable between an outer position and an inner position are coupled to respective slides and movable jointly therewith between a position extended from the door in the outer position of the respective slide and a position recessed in the door in an inner position of the respective slide. An actuating arm on the inside nut can engage stops on one of the slide and a gear train meshes on one side with the outside nut and on the other side with both of the slides for opposite movement of the two slides on rotation of the outside nut. Respective inside and outside lost-motion couplings between the inside nut and the arm and between the outside nut and the gear train permit limited angular movement of the inside and outside nuts without movement of the one slide and gear train. The nuts and handles are urged by springs into the central positions.
