The top of the panel in a window or door of the turn-and-tilt type is secured to the associated frame by a pivot assembly having a vertical axis and attached to the frame and by an arm whose one end portion is conformingly received in a connector on the pivot assembly. The connector is a channel whose flanges slope obliquely toward each other from the web so as to permit sliding longitudinal movement of the arm, but to prevent transverse movement of the arm out of the channel. Cooperating, partly adjustable abutments limit the longitudinal movement of the arm relative to the connector. The free end of the arm is movably attached to the panel top. |
