US 4,979,375 A · Mat for cooling a person during hot weather without wetting having a low manufacturing cost

Abstract

Method and apparatus for enabling a person to relax and enjoy the outdoors on a hot humid day, without being continuously exposed to water which is uncomfortable for many people. A thin flexible cooling mat is positioned upon a lounge chair or is placed flat on the ground or worn in the manner of a vest. Ordinary tap water circulates through the mat, and since the water is supplied from a conventional in ground supply main having a substantially lower temperature than the air, the person's body, in direct contact with the mat, will be kept cool. The cooling water may irrigate the backyard at the same time. Since an entire family can relax while being cooled in their back yard, air conditioners will be turned off to save money, conserve electrical power, and thus reduce atmospheric pollution.

Apparatus for cooling a person's body during hot seasons by utilizing water propelled from a conventional pre-pressurized in ground water supply main coupled to a water supply faucet comprising:

a mat having an inlet water feed means therein, means for coupling the inlet water feed means of said mat to said conventional pre-pressurized in ground water supply main via said water supply faucet as long as said apparatus is in use, an outlet water drainage means therein, and heat exchange water conduit means fully enclosed within said mat for drawing sufficient quantities of heat through a face of said mat from said person's body in direct contact with said mat by conduction and without the need to wet said body, means for coupling said heat exchange water conduit means between said inlet water feed means and said outlet water drainage means;
and
further including a flow diverter having a diverter water inlet chamber and a diverter water outlet chamber therein, first coupling means for coupling said diverter water inlet chamber to said water supply faucet coupled in turn to said conventional pre-pressurized in ground water supply main, second coupling means for coupling said diverter water inlet chamber to the inlet water feed means of said mat, and third coupling means for coupling the outlet water drainage means of said mat to said diverter water outlet chamber.

Inexpensive cooling mat apparatus for cooling a person without wetting comprising:

(a) a cooling mat including a substrate having a predetermined thickness and a first major surface and a second opposite major surface, tubeless water conducting channels, formed within said substrate, intersecting and extending from said first major surface and positioned substantially away from said second major surface, for enhancing heat flow from said person into said tubeless water conducting channels, said channels being separated from each other by solid weight supporting lands of said substrate, coplanar with said first major surface, for supporting the weight of an adult person without pinching off said water conducting channels, a cover sheet for contacting said person, laminated to said first major surface of said substrate, said cover sheet having a thickness substantially less than the thickness of said substrate for further enhancing said heat flow from said person into said tubeless water conducting channels and for containing cooling water filling said channels so as not to wet said person;
and
(b) means for coupling said water conducting channels to an in ground water supply faucet for causing cooling water to flow through said tubeless water conducting channels.
