Personnel cooler

DETAILED DESCRIPTION I claim: 1.
A flexible panel to be worn adjacent a portion of the human body for cooling, which comprises: two flexible plastic sheets which are joined to form two tortuous, adjacent, generally co-extensive, non-communicating fluid paths, one of said fluid paths being substantially and permanently filled with a viscous liquid heat transfer media and the other of said fluid paths being in communication with a reservoir of pressurized gas; means between said reservoir and said other fluid path for regulating the flow of pressurized gas through said other fluid path and a pressure relief means in said other fluid path and positioned at a point remote from said reservoir to limit the gas pressure and gas flow rate in said other fluid path; and means for holding said sheet in place adjacent a portion of the human body.
2.
The structure of claim 1 in the form of a continuous sheet.
3.
The structure of claim 1 in the form of a garment.
4.
The structure of claim 3 in the form of a vest.
5.
The structure of claim 3 in the form of a head cover.
6.
The structure of claim 3 in the form of a coat.
7.
The structure of claim 1 wherein the sheets are heat sealed.




Description:
BACKGROUND OF THE INVENTION It is a problem to protect workmen, farmers, and the like who must work in open exposed areas in hot climates from the effects of heat and sunlight.
Such persons are subject to suffering heat prostration unless great care is taken to avoid prolonged exposure.
A significant amount of time and productivity is lost due to necessity for rest stops and complete work stoppages during the late morning and afternoon hours in tropical and desert climates.
Analogous problems are also encountered by various military forces throughout the world.
The present invention is intended to solve these persistent problems in a surprising simple and inexpensive manner, and it is to be expected that my invention will be rapidly adopted, particularly in the tropical and desert areas of the world
