The present invention is a retractable screen ( 22 ) and frame ( 24 ) assembly ( 20 ). The frame ( 24 ) includes a first track ( 32 ) and a second track ( 34 ) in spaced and parallel relationship to the first track ( 32 ). The retractable screen ( 22 ) includes a canister ( 36 ), a screen cloth ( 38 ), a control bar ( 40 ), a first glide ( 42 ), a second glide ( 44 ), and a biasing device ( 46 ). The biasing device ( 46 ) is disposed between a first end ( 52 ) of the control bar ( 40 ) and the first glide ( 42 ). The first glide ( 42 ) is inserted into the first track ( 32 ) and the second glide ( 44 ) is inserted into the second track ( 34 ). The glides ( 42, 44 ) slide along the respective tracks ( 32, 34 ) while the biasing device ( 46 ) biases the first end ( 52 ) of the control bar ( 40 ) with respect to the first track ( 32 ). The biasing provided by the biasing device ( 46 ) prevents the control bar ( 40 ) from binding with the tracks ( 32, 34 ) as the control bar ( 40 ) and the glides ( 42, 44 ) are slid along the tracks ( 32, 34 ).
