A window drive mechanism includes a bracket and a cam slide moveably coupled to the bracket. In one option, the bracket is coupled to a window frame. An elongate arm is rotatably coupled to a sash substantially adjacent to a first end of the arm. In one option, the elongate arm is rotatably coupled to the bracket substantially adjacent to a second end of the arm. In another option, the elongate arm is moveably coupled to the cam slide between the first end and the second end. An actuator arm is coupled to the cam slide and operable to move the cam slide. A method for making a window assembly optionally includes providing a window frame and coupling a window drive mechanism to the window frame.

Window drive mechanism

A deformable screen for a window assembly including a sash movably coupled to a frame. The sash is moveable in a substantially horizontal direction relative to the frame. The deformable screen is coupled to the sash and includes at least one engagement portion slidably engaged against the frame. A spring member is coupled to the engagement portion and applies a restoring force to the engagement portion to seal it against the frame. In one option, the spring member includes a foam membrane. A method for making a screen assembly includes providing a frame and a sash disposed within the frame. A spring member is coupled around the sash and at least one engagement portion is coupled to the spring member. The engagement portion extends between the spring member and the window frame, in one option. In another option, the at least one engagement portion is slidably engaged against the frame.
