The invention relates to as sliding panel system. The system comprises a frame and a combination of one or more pivot panels and sliding panels. Each sliding panel is displaceable, in particular slidable, within the frame and part of the sliding panel can be fixated with respect to the frame such that the sliding panel can be pivotably displaced between a closed and an opened position.

A corner drive assembly for a window locking system includes a case, a corner transfer spring, and first and second arms. The case includes first and second legs aligned with respective first and second axes. The legs are joined by a corner portion having an outer relief surface that is disposed adjacent to and spaced apart from a corner of a window frame. The spring is slidably disposed within the corner portion and has first and second ends slidable along the first and second axes, respectively. The first arm is disposed within the first leg, slidable along the first axis, and coupled to the first end of the spring. The second arm is within the second leg, slidable along the second axis, and coupled to the second end of the spring. The first and second arms are coupled to respective first and second link bars of the locking system.

A control assembly for an outwardly opening pivoting wing, comprising an actuating device including a support, a crank rotatable with respect to the support and a control mechanism actuated by the crank, an arm having a toothed portion, wherein said control mechanism cooperates with the toothed portion of the arm for swinging the arm between a closed wing angular position and an open wing angular position.
