Abstract:
1. A hinge structure comprising: a bracket having a horizontal top panel and a side panel perpendicularly downwardly extending from one end of said horizontal top panel; a first pivot set movable between a first position and a second position, said first pivot set having a pivot shaft horizontally and rotatably inserted through said side panel of said bracket and rotatably coupled to a support, the pivot shaft of said first pivot set having two elongated ribs protruded from one end thereof and a guide groove located between said two elongated ribs; and a second pivot set movable between a locked position and an unlocked position, said second pivot set having a pivot shaft vertically and rotatably inserted through the horizontal top panel of said bracket and rotatably coupled to a mounting frame, the pivot shaft of said second pivot set having a head at a bottom end thereof, the head of the pivot shaft of said second pivot set having two flat cut faces disposed at two opposite sides; and wherein, when said first pivot set is rotated relative to said bracket to a zero angle position, said first pivot set is located in the first position and said second pivot set is located in the locked position, the two elongated ribs of the pivot shaft of said first pivot set are positioned adjacent to at least one flat cut face of the two flat cut faces of the head of the pivot shaft of said second pivot set to lock said second pivot set, prohibiting rotation of said second pivot set; wherein, when said first pivot set is rotated relative to said bracket to a predetermined angle, said first pivot set is located in the second position and said second pivot set is located in the unlocked position, the head of the pivot shaft of said second pivot set is rotatable in the guide groove between the two elongated ribs of the pivot shaft of said first pivot set to unlock said second pivot set, allowing rotation of said second pivot set.
