Patent number: 6185878Abstract: A utility shed is disclosed comprising modular side panels (30) which are connected together by corner connectors (26) and in-line connectors (28) to form sidewalls. The connectors (26, 28) have an I-beam cross section and comprise U-shaped ends (106, 80) which engage relatively wide channels (62, 64) to securely hold the wall panels together. A door assembly is provided for engaging the corner connectors (26) and include pivot pin members (202) which attached to the vertical channel (114) of corner connectors (26) and allow pivotal door panels (164) to be suspended therefrom. Floor panels (116, 118) and lid panels (154) are provided compatible with the I-beam edge configuration of the side panels (30) such that the lid, floor and sidewalls mutually interlock with high structural integrity. The modularity of the side panels (30) allow for enclosures of larger or smaller size to be created using the same panel componentry.Type: GrantFiled: May 27, 1998Date of Patent: February 13, 2001Assignee: Rubbermaid IncorporatedInventors: Hoke V.
