The present invention relates to a collapsible/foldable structure that may include a top roof and a bottom platform. A pair of sidewalls may be provided each of which may be pivotally attached to the roof. The sidewalls may include at least two side section such as an upper and middle section. The sidewalls may also include a lower side section. The upper and middle sections may be pivotally attached to one another and the middle and lower side section may be pivotally attached to one another so that the upper and middle sidewall sections can be pivoted inwardly towards the bottom platform to provide a collapsed condition. The sidewalls may also each contain an outer and an inner surface thereof wherein the outer surface of the upper side wall and the outer surface of the adjacent middle side wall form an angle that is greater than 180 degrees when the structure is in an expanded or collapsed condition. In addition, the inner surface of the middle wall section may overlie the inner surface of the upper wall section in a collapsed condition.

1. A collapsible/foldable structure comprising: a roof and a base defining a top and bottom of said structure;a lower side section permanently affixed along each side of said base;a pair of sidewalls, each comprising at least two sections, each section pivotally attached to said roof to facilitate inward collapse of said sidewalls when said sidewalls are pivoted toward said base, said sidewalls each comprising upper and middle sections, wherein said upper and middle sections are pivotally attached to one another and wherein said roof can collapse downwardly toward said base;said sidewalls having an outer and an inner surface thereof, the middle wall section being pivotally attached to the lower side section to permit folding of said middle sidewall inwardly toward said base;said upper wall section being pivotally attached to said middle wall section to permit said middle wall section inner surface to collapse into an overlying and contacting position with the inner surface of said upper wall section and said roof being pivotally connected to said two upper sidewall sections to permit said roof to be collapsed towards said base,wherein said outer surface of said upper section and said outer surface of said middle section never form an acute angle with one another. 2. The structure of claim 1 including front and rear collapsible panels each movably positioned relative to said lower side section and which are configured to collapse inwardly into said collapsible/foldable structure so that said front and rear collapsible panels may overlie one another and one of said front and rear collapsible panels may overlie said base. 3. The structure of claim 1 wherein the outer surface of said upper side wall and the outer surface of the adjacent middle side wall form an angle that is greater than 180 degrees when the structure is in an expanded or collapsed condition. 4. The structure of claim 1 wherein said pivotal attachments comprise hinges. 5. The structure of claim 4 wherein one or more of said hinges comprise a living hinge. 6. The structure of claim 5 wherein said living hinge integrally extends between the inner surfaces of said upper and said middle wall sections. 7. The structure of claim 1 wherein at least one of said pivotal attachments comprise hinges panels which include a pair of spaced-apart hinges. 8. The structure of claim 7 wherein said hinges panels comprise a flexible material capable of bending. 9. The structure of claim 8 wherein said hinges panels comprise one of leather, cloth, thermoplastic olefin or thermoplastic elastomer. 10. The structure of claim 1 wherein one or more of said roof, said upper sidewall section and said middle sidewall section are curved. 11. The structure of claim 7 wherein said hinge panels are curved. 12. The structure of claim 1 wherein said roof further includes an access panel for accessing items stores within said structure. 13. The structure of claim 1 wherein said front and rear walls are detachable from said base. 14. The structure of claim 4 wherein said hinges extend discontinuously along said side sections. 15. A foldable/collapsible structure comprising: a horizontally disposed bottom panel and a lower side section;a top panel;a pair of side walls, each defined by at least an upper and middle side sections including said lower side section;wherein said upper side section is hingedly connected to said top panel and to said middle side section, said middle section is hingedly connected to said lower side section, wherein said side panels can be pivoted inwardly towards said bottom panel;wherein said upper and said middle side sections include inner and outer surfaces and wherein the upper wall section being hingedly attached to said middle wall section permits said middle wall section inner surface to collapse into an overlying and contacting position with the inner surface of said upper wall section. 16. The structure of claim 15 including first and second end panels hingedly attached to said lower side section. 17. The structure of claim 15 wherein the outer surface of said upper side section and the outer surface of the adjacent middle side section form an angle that is greater than 180 degrees when the structure is in an expanded or collapsed condition. 18. A pet carrier for transporting or temporarily storing pets comprising: a top roof and a bottom platform defining a top and a bottom of said carrier;a pair of sidewalls each pivotally attached to said roof to facilitate inward collapse of said sidewalls when said sidewalls are pivoted toward said bottom platform,said sidewalls further containing at least an upper, middle and lower section, wherein said upper and middle sections and said middle and lower sections are pivotally attached to one another so that said upper and middle sections can be pivoted inwardly towards said bottom platform,wherein said upper and said middle sections include inner and outer surfaces and wherein the upper section being pivotally attached to said middle section permits said middle section inner surface to collapse into an overlying and contacting position with the inner surface of said upper section. 19. The structure of claim 18 wherein the outer surface of said upper side section and the outer surface of the adjacent middle side section form an angle that is greater than 180 degrees when the structure is in an expanded or collapsed condition. 20.
