Abstract: A magnetically attachable window screen for attachment to a window frame. The window screen includes a plurality of screen frame members. Each frame member includes a first end and a second end wherein the first and second ends are operable to receive a flange member. The window screen also includes a screen corner key with a central magnetic member and two orthogonally opposed flanges extending outwardly in a single plane from the central magnetic member. The flange members of the screen corner key are inserted into the first and second ends of orthogonally opposed adjacent screen frame members to form a fully assembled screen frame. The window screen also includes a plurality of corner key mates inserted into each corner of the screen channel of the window frame. The central magnetic member of the inserted corner key is operable for magnetic attraction to respective corner key mates.

Abstract: A sash latch for engagement with a side jamb of a window includes an upper member with a spring cavity and a stop wall, a forward slot for engagement with an upper surface of a sash and a latch extension. The latch extension includes a substantially planar surface and an inclined planar surface extending at an acute angle relative to the substantially planar surface. The inclined planar surface includes a notch at a proximal end thereof, wherein the notch receives an edge of a wall of the side jamb when a heavy wind load is applied to an outer facing surface of the sash to restrain the sash relative to the side jamb.

Abstract: A sash latch for use in a sash of a window frame. The latch comprising a housing installed in the sash of the window frame, the housing containing a retractable slide, a pillar formed in the housing, and an extension at an end of the slide. The slide is movable to engage the extension with the window frame to prevent the sash from moving within the window frame. A slot is formed in a side of the slide wherein when a force is applied to the sash, the slide and the housing are deformed such that the pillar is received by the slot and prevents the slide from moving and disengaging the extension from the window frame.

Abstract: A sash latch for retractable engagement with a side jamb of a window includes a lower member, which is fixed to a sash of the window, and an upper member with an extension. The upper member and extension slide relative to the lower member so that the extension can extend beyond the sash and can retract into the sash. In use, the extension extends beyond the sash and into the side jamb. A planar surface of the extension locks the sash to the side jamb. The extension also has a notch located opposite the planar surface. The notch prevents the extension from retracting into the sash when a heavy wind load is placed on the sash. Advantageously, this inhibits the sash from swinging dangerously inward under such a condition and reduces the possibility of damage or death.

Abstract: A sash latch for retractable engagement with a side jamb of a window, the sash latch comprising an upper member with an upper surface and a lower surface, a spring cavity with a stop wall, forward and rear slots for engagement with an upper surface of the sash, an extension with a notch, the extension for retractable receipt into an opening in a side jamb of the window. The latch also includes a lower member and a plunger arm with a distal end extending outwardly from the support member, the distal end including an engagement nub, a spring with a first end and a second end for receipt into the spring cavity of the upper member, the first end of the spring for contact with the stop wall of the upper member, the second end of the spring for engagement with the engagement nub of the plunger.
