#Applicant claims the benefit of application Ser. No. 14/121,930, filed Nov. 6, 1014, which claimed the benefit of provisional application Ser. No. 69/962,798, filed Nov. 18, 2013.

#The present invention relates to a self-contained air distribution system for particular use by an individual to prevent heat stress and fatigue by evaporating body moisture and perspiration when exposed to high ambient temperature. The present invention as described has a particular cooling and evaporative effect.

#These and other objects of the present invention will become apparent, particularly when taken in light of the following illustrations wherein:

#FIG. 1 is a front planar view of the portable self-contained air distribution system of the present invention;

#FIG. 2 is a front view of the portable self-contained air distribution system positioned about the torso of an individual;

#FIG. 1 is a front view of the portable self-contained air distribution system of the present invention. The portable self-contained air distribution system 10 is described initially with respect to its adaption to use by a human individual who is required to perform physical activity in ambient atmosphere which is conducive to excessive perspiration. This would include construction workers, astronauts, military personnel, hazardous waste clean up individuals, fire fighters, and others who oftentimes are required to wear substantial protective clothing and equipment. The distribution of air by the system will have a cooling and evaporative effect on the individual wearing the system, either directly to the skin or the clothing. It will also be understood that while the preferred embodiment is illustrated with two adjustable, flexible waist mounted distribution exhaust outlet openings, the system can be operated with a single adjustable, flexible distribution exhaust outlet opening or more than two adjustable distribution exhaust outlet openings without departing from the spirit and scope of the invention.

#The portable self-contained pressurized air distribution system 10 as illustrated in FIG. 1 is adapted for human use. The system may comprise an outer protective shell (not shown) to shield the contents from dirt, dust, and particulate matter. The outer protective shell is formed with an optional filter aperture. Positioned within the optional outer protective shell is an electric blower fan assembly 12 and inlet port 13 that is energized by a portable rechargeable battery pack 14 or other power supply that is connected to a selective on/off switch 16. The blower fan assembly is in communication with a plenum manifold 18 having a plurality of outlet ports 20 attached to adjustable, flexible distribution conduits 32 and 32A that are connected to adjustable, flexible primary exhaust outlet openings 33.

#Outlet ports 20 have secured thereto primary adjustable flexible adjustable directional conduits 32 and 32A which extend from a respective outlet port to a selected position about the upper or lower body. The select position about the body could be the upper or lower back or the upper or lower chest of an individual. The terminus 34 and 34A of adjustable, flexible directional conduits 32 and 32A is formed with adjustable, flexible exhaust outlet openings 33 which will disburse the air flow from the energized blower fan assembly 12 upwardly or downwardly across the individual's back or across the individual's stomach and chest or legs, either directly over the skin or the clothing, thus providing a cooling and evaporative affect to the individual.
