Frame assembly including a cornerlock

A frame assembly for disposing within an opening of a structure, said frame assembly comprising:

• a first frame member and a second frame member each having a plurality of walls extending between a first end and a second end which is spaced from said first end, and having a cross-section between said first end and said second end with each of said cross-sections defining an interior and being capable of varying between said first and second ends;
• and
• a cornerlock extending into each of said first and second frame members to couple together said first and second frame members, said cornerlock comprising:
• a first body member configured to mate with said interior of said first frame member and a second body member configured to mate with said interior of said second frame member, with each body member having a hinge end and a distal end spaced from said hinge end, and with said first and second body members rotatably coupled together at said hinge ends;
• wherein said first body member has at least one arm extending from said hinge end to said distal end with said at least one arm deflectable about said hinge end to bias against and engage said first frame member within said interior of said first frame member and self-configure said first body member to said cross-section of said first frame member;
• wherein each of said first and second frame members have a mitered end with said cornerlock extending into said interiors of said first and second frame members at said mitered ends, with said first and second frame members abutting at said mitered ends in an angular configuration and with said cornerlock configured to rotate said first and second body members to correspond with said angular configuration of said first and second frame members such that said cornerlock is entirely disposed within a combination of said interiors of said first and second frame members at said mitered ends;
• wherein said first frame member has an arcuate configuration with said at least one arm deflectable to engage said first frame member and self-configure said first body member to said cross-section of said first frame member along said arcuate configuration;
• and
• wherein said first body member has a pair of engagement surfaces opposing one another for engaging said walls within said interior of said first frame member, with each of said pair of engagement surfaces defining a distal ridge adjacent said distal end of said first body member, a hinge ridge adjacent said hinge end of said first body member, and a recess between said distal and hinge ridges, wherein said distal and hinge ridges engage said walls within said interior of said first frame members adjacent said distal and hinge ends to prevent movement between said first body member and said first frame member, with said recess spacing said first body member from said first frame member between said distal and hinge ridges to prevent engagement of said first body member with said walls between said distal and hinge ridges as said cross-section of said first frame member varies between said first and second ends along said arcuate configuration and prevent rotation of said first body member relative to said first frame member.
