Abstract:
1. A wild fire fighting water bucket “Rim Opening Device”, which being mechanical, collapsible, symmetrical and polygonal in form and shape, is circumferentially disposed around and affixed inside the rim of the pliable, collapsible aerial wild fire fighting water bucket, which is dimensional as such to be suspended from a helicopter, and to be filled by dipping into an open body of water, the “Rim Opening Device” cooperating with the pliable side walls of the wild fire fighting water bucket to automatically open both concentrically when under tension from a helicopter and to automatically hold and lock open same, and to selectively accommodate manual collapse of both the Rim Opening Device and the pliable, collapsible wild fire fighting water bucket, the Rim Opening Device comprising: (a) a plurality of interconnected mechanical wishbone apparatuses comprising; (b) an angle of inclination which converts lifting tension to horizontal, concentric development of the Rim Opening Device, (c) a connector swing arm tract which guides the Rim Opening Device's concentric development, (d) a Rim Opening Device integrated weight differential system comprising; (e) vertically arranged, interconnected structural components of a collapsed Rim Opening Device, ie, the Mechanical Swing Arms, Fixed End Connectors, and the Free End Connectors embody design content and capacity to progressively transition perpendicularly therefrom into a defined horizontally arranged closed plane, symmetrical and polygonal in form and shape, having a centrally open orifice providing unrestricted access into the interior of the wild fire fighting water bucket.
