Insect Screen Structures

A frame comprising:

• a plurality of engagement members arranged such that adjacent two of said engagement members meet at respective corners, each said engagement member having an outer edge and an inner edge adapted for use as a retaining structure for a product having a flexible two dimensional material secured to the retaining structure extending from said inner edge of the engagement member, said engagement member having a substantially uniform cross-section with first and second parts connected by a longitudinally extending hinge line, one of said first or said second parts including a wall formation extending longitudinally and the other of said first or said second parts including a longitudinally extending first groove complementary in shape to said wall formation whereby in a first relative configuration of said first and second parts said wall formation is fully free of said first groove and in a second relative configuration of said first and second parts said wall formation is engagable in said first groove, said first groove and said wall formation being inclined towards said outer edge when in said second configuration.

An insect screen panel comprising:

• a frame having an internal space defined by a plurality of peripherally positioned engagement members, each said engagement member having an outer edge and an inner edge adapted for use as a retaining structure for a product having a flexible two dimensional material secured to the retaining structure extending from said inner edge of the engagement member, said engagement member having a substantially uniform cross-section with first and second parts connected by a longitudinally extending hinge line, one of said first or said second parts including a wall formation extending longitudinally and the other of said first or said second parts including a longitudinally extending first groove complementary in shape to said wall formation whereby in a first relative configuration of said first and second parts said wall formation is fully free of said first groove and in a second relative configuration of said first and second parts said wall formation is engagable in said first groove, said first groove and said wall formation being inclined towards said outer edge when in said second configuration;
• and
• a flexible mesh screen material covering said internal space, said mesh screen material having edge zones captured and retained in said first grooves of the engagement members.
