A framed window screen formed from four (4) rails which each include a channel, a wide groove and a narrow groove and are each cut at a forty-five degree (45°) angle at the terminal ends. A durable, sturdy corner connector joins each rail one to another, which may be molded from a durable polymeric material having an L-shaped member, a groove support and a stanchion. The groove support is V-shaped and joined to the L-shaped member by a rib. Each end of the L-shaped member of the connector is inserted into adjacent rail channels with the groove support positioned in the wide grooves of the adjacent rails. Once the screen frame is assembled using the connectors, a suitably cut screen wire can be placed over the frame with the edges proximate the narrow groove whereby a rubber seal is inserted to maintain the screen in the narrow groove by friction.

Between the damper on a shaft fixed to the winding box and the winding shaft, a one-way clutch mechanism is interposed such that, when the winding shaft is rotated in a screen deploying direction, the connection between the damper and the winding shaft is cancelled while when the winding shaft rotates in a screen winding direction the damper is connected to the winding shaft.

The present invention is a screen frame and screen positionable in most window frames and door frames. The invented screen frame is comprised of four screen frame segments joined together at corners to form a generally rectangular or multi-sided screen frame. Corner joint inserts are inserted in each corner of the four screen frame segments and the inserts are spot welded to adjoining screen frame segments to provide a sturdy and rigid screen frame. The screen frame segments are preferably stainless steel extrusions having two parallel flanges extending from a generally square shaped hollow body. An alternative construction of the screen frame is a continuous extruded segment that is notched at certain locations for bending and forming into a continuous screen frame having one junction requiring spot welding. A metal, preferably stainless steel screen is secured in the screen frame by spot welding the screen between the screen frame flanges of the screen frame segment. Stainless steel support pins are used to secure the screen frame enclosing the screen in a window frame casing. The screen frame and screen provides a long-lasting, corrosive resistant, and rigid frame and screen for positioning in window or door frames which withstand damage from intruders, projectiles, and environmental stresses.
