Patent ID: 7418805

Claim:
A method of constructing a modular framing system, including orthogonal frames arranged with corresponding edges positioned in close proximity to one another, each orthogonal frame being formed from two horizontal and two vertical frame elements, each frame element being equipped with a frame slot and a plurality of locks positioned between adjacent vertical frame elements, the method comprising the steps of: providing a first and a second orthogonal frame each formed from two horizontal frame elements and two vertical frame elements, a first vertical frame element of the first orthogonal frame configured to be connected to a second vertical frame element of the second orthogonal frame; providing a frame slot that includes a lock guide with an enlarged head placed inside a U-shaped channel of each vertical frame element; providing a double lock at a bottom section of the first vertical frame element; providing a plurality of single locks equi-distantly spaced along a length of the second vertical frame element; inserting the second vertical frame element into an intermediate section of the first vertical frame element; sliding one of the first and second vertical frame elements relative to one another to interlock the double lock fitted at the bottom section of the first vertical frame element; and interlocking top sections of the first and second vertical frame elements with another double lock.
