- This invention relates to the production of window frame systems and, more particularly, to structure for reinforcing and sealing composite window frames.
- Window frames made of composite material such as vinyl have gained popularity due to their lightweight and corrosion resistance. However the production process is long, tedious and marred with inconsistencies in quality, physical dimensions and architectural nature the corners and other joints of conventional composite windows may not be sufficiently robust due to the material having low rigidity, becoming brittle and damaged by the clean up process. Thus, there is a need to provide a reinforcing structure to strengthen a composite window frame and a mechanism for sealing the corner from air and water infiltration.
- An object of the invention is to fulfill the need referred to above. In accordance with the principles of the present invention, this objective is achieved by a method of creating a better process for producing the window system as well as sealing and reinforcing a composite frame. The method includes receiving material for processing, the material having surfaces defining at least one continuous channel therein; cutting the received material to a desired length; forming at least one notch in the material by cutting the material at certain angles thereby defining a pair of notch surfaces; placing reinforcing structure within at least a portion of the channel; and folding the material at the notch so that the notch surfaces are in abutting relation and moving the ends to be in abutting relating to define a closed frame with the reinforcing structure, disposed within the channel in the closed frame, providing sealing properties and reinforcement to the frame.
- In accordance with another aspect of the invention, a frame structure includes a composite frame defining a closed structure. The closed structure has an interior periphery defining a portion of a continuous channel in the frame. A reinforcing structure includes a main body secured within the channel at a certain location, and a cable structure or roll-formed metallurgical materials having first and second ends. The first end is coupled with the main body. The cable structure extends from the certain location about the periphery and within the continuous channel and back generally to the certain location with the second end being secured to the main body so that the cable structure provides compression to the frame.
