ABSTRACT:
The present invention10discloses a collapsible pod for providing cathodic protection to a preferred structure12.The present invention10has a top frame20and a bottom frame22with a plurality of folding leg segments24positioned therebetween. The leg segments are comprised of the anode material having a pivot30positioned at each distal end. Also extending between the top20and bottom22frame is the folded retaining means28that prevents random deployment of the structure. To expand the structure the folded retaining means28is disengaged whereby the top20and bottom22frame are spaced apart by the segmented leg elements24.Also shown are stabilizers26and a rest channel32for the upper anode. Also disclosed is a lock bracket34forming a dual pivot point30for each leg segment24.The lock bracket34provides means whereby each leg segment24lays in communication with each other adding rigidity to the folded structure. The lock bracket34has pins45, 46passing through a slot52in the guide bar extending from the distal ends of the leg segment24.As the guide bar50moves into linear alignment with the lock bracket30the opposing guide bars move into the lock bracket and are then locked into the extended position.
