Patent ID: 7178292

Claim:
A dual-opening mechanism of a door comprising: first and second pairs of hinges comprising: first and second pairs of stationary hinge parts each having a hinge knuckle, and each pair attached on the opposite sides of an opening of a casing, first and second pairs of moving hinge parts releasable from said first and second pairs of stationary hinge parts, each having hinge knuckles, and each pair attached in the opposite sides of a door for opening and closing said opening of the casing, and first and second pairs of hinge pins, one pair removably inserted into the hinge knuckles of one of said first and second pairs of stationary hinge parts and into the hinge knuckles of one of said first and second pairs of moving hinge parts, and the other pair into the hinge knuckles of the other of said first and second pairs of stationary hinge parts and into the hinge knuckles of the other of said fist and second pairs of moving hinge parts, to couple said stationary hinge parts to said moving hinge parts; first and second hinge pin drive mechanisms, each moving one of said first and second pairs of hinge pins together in inward and outward linear motion to drive the hinge pins into or out of the hinge knuckles of the stationary and moving hinge parts; and first and second handles each operatively linked to one of said first and second hinge pin drive mechanisms for operating the first or second pair of hinge pins; wherein the door is opened/closed by selectively operating either one of said first and second handles to draw either one of said first and second pairs of hinge pins out of the corresponding one of said first and second pairs of hinges, and pivoting the door around the other pair of hinge pins coupled to the corresponding other of the first and second pairs of hinges.
