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.
1. A collapsible storage box, comprising:
a first sub-assembly, a second sub-assembly, and a third sub-assembly, the sub-assemblies being releasably attached to each other to form the collapsible storage box; wherein
the first, second and third sub-assemblies have approximately equal footprints when collapsed;
the first sub-assembly comprises a base of the collapsible storage box;
the second sub-assembly comprises a front and sides of the collapsible storage box, the sides including a first side and a second side, the first side being attached to the front with a first hinge and the second side being attached to the front with a second hinge, each of the front and the sides having an interior face and an exterior face, wherein, when the second sub-assembly is collapsed, the sides lying flush with the front such that the interior face of each of the sides directly contacts the interior face of the front;
the third sub-assembly comprises a top and a back of the collapsible storage box, the top being attached to the back with a second hinge; and
the collapsible storage box includes a locking mechanism so that contents of the box are secured when the top of the collapsible storage box is closed.
2. The storage box of claim 1 , wherein:
the locking mechanism comprises a lock, an actuation bar that pivots on a pin, and an actuating slider that engages and disengages the locking mechanism.
3. The storage box of claim 2 , wherein:
when the lock is removed from a receiving compartment, a release lever is actuated so that the locking mechanism moves from a locked position to an open position so that the storage box can be opened.
4. The storage box of claim 1 , wherein:
the first, second, and third sub-assemblies are joined together by a mechanism that does not require any tools to disassemble the sub-assemblies from each other.
5. The storage box of claim 1 , wherein:
the base of the storage box is approximately twice as thick as the sides and top of the storage box.
6. The storage box of claim 1 , wherein:
at least one of the sub-assemblies includes a handle to facilitate lifting and carrying of the at least one sub-assembly.
