Collapsible cage

A collapsible cage for housing an animal, said collapsible cage having an expanded and a collapsed configuration, said collapsible cage comprising:

• a top platform and a bottom platform defining a ceiling and a floor of said collapsible case;
• a first accordion wall having a first upper portion and a first lower portion, said first upper portion having a first upper end rotatable engaged to said top platform, said first lower portion having a first lower end rotatably engaged to said bottom platform, and said first upper portion rotatable engaging said first lower portion along a hinge intermediate of said first upper end and said first lower end;
• a second accordion wall having a second upper portion and a second lower portion, said second upper portion having a second upper end rotatable attached to said top platform, said second lower portion having a second lower end rotatable attached to said bottom platform, and said second upper portion rotatable engaging said second lower portion alone a hinge intermediate of said second upper end and said second lower end;
• a first end wall rotatable engaging said bottom platform;
• a second end wall rotatably engaging said top platform;
• wherein said top and bottom platforms, first and second end walls, and first and second accordion walls define a cage interior when said collapsible cage has said expanded configuration;
• wherein during the transition from said expanded configuration to said collapsed configuration said first and second end walls and said first and second accordion walls pivot into said cage interior and said top platform approaches said bottom platform;
• wherein a door wall chosen from a group consisting of said first end wall, second end wall, first accordion wall, and second accordion wall, said door wall comprising a door frame defining an entryway through said door wall, and a door rotatable engaging said door frame along a door hinge;
• wherein said door wall is said first end wall;
• wherein said door rotatable engages said door frame along said door hinge adjacent to said entryway
• wherein said door has a securing extension, said door frame has a receiving element, and said rotatable engagement between said door and said door frame permits movement of said door parallel to said door hinge whereby said securing extension may be raised over said receiving element to prevent the accidental opening of said door.

A collapsible cage for housing an animal, said collapsible cage having an expanded and a collapsed configuration and defining a cage interior, said collapsible cage comprising:

• top and bottom platforms defining the top and bottom of said collapsible cage;
• first and second accordion walls each having opposite ends rotatably engaging said top and bottom platforms and hinged at an intermediate position between said opposite ends, to provide for a rotational collapse of said first and second accordion walls against said top and bottom platforms for portable transport of said collapsible cage in said collapsed configuration, and to provide for an expansion of said first and second accordion walls into said expanded configuration for use in housing an animal;
• a first end wall rotatably engaging an individual one of the top and bottom platforms to facilitate the collapse of said first and second accordion walls when said first end wall is pivoted into said cage interior;
• a second end wall rotatably engaging the individual one of the top and bottom platforms not engaged to said first end wall, to facilitate the collapse of said first and second accordion walls when said second end wall is pivoted into said cage interior.

• a first end wall rotatable engaging an individual one of the top or bottom platforms to facilitate the collapse of said first and second accordion walls when said first end wall is pivoted in to said cage interior;
• a second end wall rotatable engaging the individual one of the top or bottom platforms not engaged to said first end wall, to facilitate the collapse of said first and second accordion walls when said second end wall is pivoted into said cage interior;
• wherein the rotatable engagement of said first end wall to an individual one of said top or bottom platforms, combined with the rotatable engagement of said second end wall to the other of said top or bottom platforms, facilitates transformation of the cage into either an expanded or collapsed configuration;
• wherein a door wall chosen from a group consisting of said first end wall, second end wall, first accordion wall, and second accordion wall, said door wall comprising a door frame defining an entryway through said door wall, and a door rotatably engaging said door frame along a door hinge;
• wherein said door wall is said first end wall;
• wherein said door rotatable engages said door frame along said door hinge adjacent to said entryway;
• wherein said door has a securing extension, said door frame has a receiving element, and said rotatable engagement between said door and said door frame permits movement of said door parallel to said door hinge whereby said securing extension may be raised over said receiving element to prevent the accidental opening of said door.
