Abstract:
A method of constructing a leg release mechanism for a portable sign stand, the method comprising the steps of:forming a lock-pin having a first leg, a second leg, an engagement element formed on said first leg and a stop; forming a leg member having a side wall defining an interior volume and first and second apertures formed through said side wall; inserting said lock-pin into said leg member in a first direction such that said first leg is received in said first aperture and said second leg is received in said second aperture simultaneously; positioning said lock-pin in an extended position such that said stop engages said leg member and said engagement element is located within said interior volume; forming a leaf spring having a slot formed therein; applying a compressive force on said leaf spring and simultaneously inserting said leaf spring into a first end of said leg member such that said slot circumscribes said first leg; and releasing said compressive force on said leaf spring such that said engagement element engages said leaf spring to bias said lock-pin toward said extended position.
