US Patent 11046480 Collapsible toolbox

This disclosure relates to portable storage boxes, also called job boxes, that may be adapted for use on construction sites. Existing boxes are typically too large and heavy to move by just one person without additional equipment. Existing storage boxes are difficult to maneuver in tight spaces. This invention allows a job box to be broken down into three sub-assemblies of roughly equal size. The individual sub-assemblies are easier to carry since they are compact and can be held close to the body when the user is in a standing position. The individual sub-assemblies stack well against each other allowing the storage box to be stored and transported in a more space efficient way than present art unitary assembly storage boxes.
