Abstract
A hinge mechanism rotatably joins a post and a hinge in a manner that allows for rapid assembly and disassembly. A first stop, second stop, and third stop are used to create a gravity-assisted rotation system for the hinge mechanism, with the hinge rotating between a horizontal locked position, raised unlocked position, and rotated collapsed position. A pin is placed through corresponding pin receptacles of the post and the hinge in order to secure the two together. The pin is locked within the post by a locking member, which secures the pin in a manner that facilitates easy pin insertion and removal. The hinge mechanism can be integrated into a variety of apparatuses, such as a table with rotating top; the top can be rotated to the collapsed configuration in order to serve as a seat back or left in the locked configuration to be used as a table top.
