SCREEN FRAME HAVING CORNERS UNDER COMPRESSION |
摘要 |
A frame for a ventilation screen-frame assembly includes a body having a mounting surface for receiving ventilation screen material. In one example, the body has at least three V-shaped cuts partially through it. Each V-shaped cut leaves an edge of the body uncut. The body is folded about each uncut edge so that the ends of the body meet at a corner. Each V-shaped cut subtends an angle 2 that is slightly less tha n 90 degrees, so that the folded corners are in compression. The assembly further includes a single corner key for joining the ends of the body into a closed frame. A reinforcement clip may optionally be provided in each folded corner.
