DOOR WITH RETRACTABLE SCREEN
A door incorporating at least one movable glass insert or window sash slidably disposed in at least one track thereof. An end of the insert is coupled to an end of a spring biased roll of screen. As the insert moves from the spring biased roll, the screen is extracted therefrom providing a continuously variable screened region in the door. The insert can be positioned using a counterbalance, spaced apart latchable locations in the door, frictional engagement, or through the tension force of the biased roll of screen. A catch mechanism is disposed on the movable glass insert to detachably couple the glass insert to a portion of the door.
1 . A catch mechanism for securing a selectively shiftable element received in a storm door, the catch mechanism comprising:
a handle body presenting a first end with a projecting boss portion and a lip structure, the lip structure spaced apart from and extending generally parallel with the boss portion, the boss portion receivable in a seat defined in the shiftable element such that the handle body is selectively pivotable relative to the shiftable element between a first position in which the lip is engagable with a corresponding receiving structure on the storm door to inhibit movement of the shiftable element, and a second position in which the lip is clear of the receiving structure of the storm door to enable movement of the shiftable element; and
a spring engagable with a portion of the shiftable element to bias the handle body toward the first position.
