Window screen assembly with dual side expanders to reduce measurements and accuracy needed for selection/installation

A screen assembly, said screen assembly comprising:

• a frame including a first side, a second side, a third side, and a fourth side, wherein the first side meets the third side at a first upper corner, the first side meets the fourth side at a first lower corner, the second side meets the third side at a second upper corner, and the second side meets the fourth side at a second lower corner;
• a mesh, said mesh being secured to said frame;
• a first expander member, said first expander member being mounted to the first side of said frame, and thereat configured to slide with respect to said frame between a first expander member fully retracted position, a first expander member fully extended position, and a plurality of first expander member intermediate positions between said first expander member fully retracted position and said first expander member fully expanded position, wherein a portion of the first expander member comprises a cantilevered spring clip that deflects to allow attachment of the first expander member to the first side of the frame;
• a second expander member, said second expander member being mounted to the second side of said frame, and thereat configured to slide with respect to said frame between a second expander member fully retracted position, a second expander member fully extended position, and a plurality of second expander member intermediate positions between said second expander member fully retracted position and said second expander member fully expanded position;
• a first leaf spring disposed between the first side of the frame and the first expander member, the first leaf spring comprising:
• a first end, said first end comprising:
• a hook and an extension;
• wherein said hook is configured to secure said first end of said first leaf spring to said first side of said frame, said hook at said first end of said first leaf spring being secured proximate to an upper end of said first side of said frame;
• wherein said hook and said extension are configured to inhibit lateral movement of said first end of said first leaf spring relative to said frame in each of a direction towards said upper end of said first side of said frame and a direction towards a lower end of said first side of said frame;
• and
• a second end, said second end comprising:
• a concave shape configured to bear against a side of said frame between said upper end of said first side of said frame and said lower end of said first side of said frame, and configured to slide against said first side of said frame when said first leaf spring is compressed;
• wherein said first leaf spring is configured to bias an upper end of said first expander member toward said first expander member fully extended position;
• a second leaf spring disposed between the first side of said frame and the first expander member, the second leaf spring comprising:
• a first end, said first end of said second leaf spring comprising:
• a hook and an extension;
• wherein said hook of said second leaf spring is configured to secure said first end of said second leaf spring to said first side of said frame, said hook at said first end of said second leaf spring being secured proximate to said lower end of said first side of said frame away from first lower corner;
• wherein said hook and said extension of said second leaf spring are configured to inhibit lateral movement of said first end of said first leaf spring relative to said frame in each of a direction towards said lower end of said first side of said frame and a direction towards said upper end of said first side of said frame;
• and
• a second end, said second end of said second leaf spring comprising:
• a concave shape configured to bear against said first side of said frame between said second end of said first leaf spring and said lower end of said first side of said frame, and being configured to slide against said first side of said frame when said second leaf spring is compressed;
• wherein said second leaf spring is configured to bias a lower end of said first expander member toward said first expander member fully extended position;
• a third leaf spring disposed between the second side of said frame and the second expander member to bias an upper end of said second expander member away from the second side of said frame;
• a fourth leaf spring disposed between the second side and the second expander member to bias a lower end of said second expander member away from the second side of said frame;
• wherein a lateral distance across said screen assembly between distal sides of said first expander member and said second expander member, when said first expander member is in said first expander member fully retracted position and said second expander member is in said second expander member fully retracted position and each of said first leaf spring, said second leaf spring, said third leaf spring, and said fourth leaf spring are compressed, permits insertion and placement of said screen assembly into a window socket of a master window frame;
• and
• wherein a lateral distance across said screen assembly between the distal sides of said first expander member and said second expander member when said first expander member is thereafter biased into one of said plurality of first expander member intermediate positions and second expander member is thereafter biased into one of said plurality of second expander member intermediate positions, permits retention of at least a portion of said first expander member in a first side of said window socket and retention of said second expander member in a second side of the window socket.
