Abstract
A vinyl window or door screen frame which does not require clips or hooks for installation. The frame contains corner keys formed at angles greater than 91.degree. which provide a slight bow along each side of the screen frame. This feature allows the screen frame to fit snugly into the window frame. The use of vinyl makes the screen frame flexibly rigid and thus allows for the bow in the frame. The frame stays in place due to the compression force between the window frame and the bowed edges of the screen frame.
Claims20
A removable screen frame for fitting into a door or window frame comprising:
- a first and second pair of slightly flexible, approximately parallel segments, where each said segment of each said pair is of same length;
- said segments being arranged in an approximately rectangular shape;
- and
- each of said segments having opposed ends with each said end of said segments of said first pair being connected to a respective end of a respective segment of said second pair at an angle greater than 91.degree. forming an outwardly bowed shape under an expansion force for retaining said screen frame within said door or window frame,
- a screen retained by the segments;
- said angle of greater than 91.degree. being retained when screen material is stretched between said segments.
A screen support and framing combination comprising:
- an outer frame containing an opening of generally rectangular shape;
- and
- a screen support and framing combination comprising:
- a screen frame of approximately rectangular shape slightly smaller than said outer frame which can be removably fitted into said outer frame with each corner of said screen frame formed at an angle greater than 91.degree. forming an approximately rectangular outwardly bowed shape under an expansion force wherein said screen frame is retained within said outer frame by said expansion force exerted by the outer edge of said screen frame against the inner edge of said outer frame;
- a screen retained by the screen frame;
- said angle of greater than 91.degree. being retained when screen material is stretched between said screen frame.
