An operator assembly may move a window vent relative to a frame. The operator assembly includes a stationary member, an arm and a drive member. The arm is mounted for rotation relative to the stationary member between an open position and a closed position. The drive member is received in a channel defined by the stationary member for linear motion therein relative to the stationary member and the arm among a first position in which the drive member engages a locking feature of the window vent, a second position in which the drive member is spaced apart from and disengaged from the locking feature without rotating the arm out of the closed position, and a third position in which the drive member is further spaced apart from the locking feature. Movement of the drive member between the second and third positions moves the arm between the closed and open positions.

A mechanism for a covering such as an encasement window or door or awning is provided. The mechanism includes an arm, on which a slot is configured. The slot includes a straight section and an angled section. The arm also includes a hole that is offset from the centerline of the straight section and disposed between the angled section and an end of the arm. A pin shaft is disposed in the hole and held in place by a cover member and a movable member, enabling the arm to rotate about the pin shaft. A rivet pin is disposed in the slot and fixedly connected to a fixed member. When the movable member moves, the arm moves such that the hung sash is unlocked from the fixed frame of the covering, and the angled section engages the rivet pin, causing the arm to rotate to open the covering.
