BACKGROUND OF THE INVENTION
Field of the Invention
The present invention is illustrated by an air beam supported tent structure 100 having a tent fly cover 102 supported by a plurality of air beam support legs 104connected one to another at their upper ends and with each said support leg having an integrated air beam support leg anchoring weight baffle pocket assembly 30 formed at the lower distal end of each said support leg and with each said pocket assembly sized to receive, cooperate, and retain a selected weight bag 110 (selectively filled with a selected weight medium of water, sand, steel shot, lead shot, or other pourable weight material) or formed metal weight plate or other heavy object to anchor the leg relative to the underlaying ground surface or other underlaying surface upon which each said lower distal end is placed. See FIG. 5.
The present invention is an improvement over other anchoring systems that use guy lines attached to laterally displaced ground stakes or external sand bags or other external weights attached to the exterior of the tent structure or air beam support legs. The present invention provides a cleaner more attractive profile to anchored air beam support legs than can be achieved with prior art anchoring systems that often use exterior weights attached to the exterior of the air beam support leg.
The present invention provides an anchored air beam structure that is less likely to exhibit a human tripping hazard that often is exhibited by other anchoring systems that often use guy lines with stakes or sandbags or other ballast objects attached externally to the air beam structure.
BRIEF SUMMARY OF THE INVENTION
A principal objective of the invention is to provide a tent structure manufacturer or an air beam structure manufacturer or other structural air beam user with an improved structural air beam support leg including an anchoring weight baffle pocket assembly 30 that is internal to each said air beam support leg used in a structure that is simple to use, less hazardous to users by reducing a potential tripping hazard, low-maintenance, and reliable.
Additional and various other objects and advantages attained by the invention will become more apparent as the specification is read and the accompanying figures are reviewed.
