Claim 7:
8. A fenestration assembly comprising:
at least one sash comprising:
a first rail;
a second rail opposite the first rail;
two stiles connecting the first rail to the second rail; and
a window pane surrounded by the first rail, the second rail, and the two stiles;
a frame surrounding the at least one sash, the frame including:
a first portion;
a second portion opposite the first portion; and
two jambs connecting the first portion to the second portion, the at least one sash slidably engaged with the two jambs between an open configuration in which the first rail of the at least one sash is not in contact with the first portion or the second portion, and a closed configuration in which the first rail of the at least one sash is in contact with the first portion or the second portion; and
at least one retractable screen system comprising:
a pair of edge rails coupled to the two jambs on opposite sides of the frame, each of the pair of edge rails forming a rail slot;
a catch assembly coupled to an outer surface of the first rail,
the catch assembly comprising a catch element; and
a screen assembly comprising:
a roller housing coupled to an outer surface of the first portion;
a roller assembly disposed within the roller housing and substantially hidden from view;
a control bar projecting beyond the at least one sash and into each of the rail slots, the control bar comprising a hook element extending along at least a portion of the control bar, the hook element configured to selectively engage the catch element; and
screen material coupled to the roller assembly, edges of the screen material projecting into each of the rail slots and an end of the screen material coupled to the control bar; the roller assembly configured to apply tension to the screen material to wind the screen material around the roller assembly and to permit the screen material to unwind from the roller assembly when the hook element engages the catch element as the at least one sash slides away from the roller assembly, wherein the hook element automatically engages the catch element when the at least one sash transitions from the closed configuration to the open configuration,
wherein the catch assembly is operable to rotate away from the control bar of the screen assembly when the at least one sash is rotated out-of-plane, and
wherein the at least one sash is configured to tilt out of a plane formed by the frame, automatically disengaging the hook element from the catch element.
