Foldable cabinet

A cabinet, comprising:

• a front;
• a back wall;
• a first sidewall rotatably coupled to the front and to the back wall, wherein the first sidewall is rotated inward when the cabinet is folded or collapsed, and outward when the cabinet is expanded, and wherein the first sidewall includes a front portion pivotally coupled to a back portion such that the front portion and the back portion are folded when the cabinet is folded or collapsed, and expanded when the cabinet is expanded;
• a second sidewall rotatably coupled to the front and to the back wall, wherein the second sidewall is rotated inward when the cabinet is folded or collapsed, and outward when the cabinet is expanded, and wherein the second sidewall includes a front portion pivotally coupled to a back portion such that the front portion and the back portion are folded when the cabinet is folded or collapsed, and expanded when the cabinet is expanded;
• and
• a first hinge base bracket mounted on the front portion of the first sidewall;
• a second hinge base bracket mounted on the back portion of the first sidewall;
• and
• a strap hinge used to pivotally couple the front portion of the first sidewall to the back portion of the first sidewall, and
• wherein the strap hinge includes a hinge bracket mounted on top of the first hinge base bracket and the second hinge base bracket, and
• wherein the strap hinge includes strap portions that are coupled to the first hinge base bracket, the second hinge base bracket, and the hinge bracket to connect the front portion to the back portion of the first sidewall, and wherein the strap portions are generally oval-shaped rings and are received through holes on opposite ends of the hinge bracket to rotatably couple to the hinge bracket such that when the first sidewall is folded, the strap portions rotate around the opposite ends of the hinge bracket to allow the first sidewall to be folded.
