Recirculated self-heating air delivery system to warm the body

Abstract

A conduit for delivering warm air to the body with a multiplicity of warm air delivery holes arrayed along extensive tubing down extending over the arms and legs of the wearer. The warm air is derived from the user's expired air as one exhales into a coupler that fits the mouth of a human or coupled to an over the nose and mouth facemask. The exhaled air travels through the mouthpiece or mask and into the tubing to be delivered to the extremities through air dispersion holes arrayed along and around the tubing.

Description

BACKGROUND OF THE INVENTION[0001]This invention relates to thermal heating devices for outdoor wear. The warm air delivery system of the present invention provides a warmed air thermal protective layer between the exterior weather protection garments and the street clothes of the user, which insulates the human from the exterior weather and maintains a heated thermal barrier. The invention uses a multiplicity of air delivery holes along a network of tubing with an inlet to the tubing delivery system forming a coupler to fit the mouth of a human, or an over the nose and mouth face mask, to achieve its goal.[0002]Hunters, construction workers, motorcycle riders, snowmobilers, and other outdoor enthusiasts often are exposed to cold weather for prolonged periods of time. Ideally the user would be someone who is outside in temperatures of 20° F. or below for an extended period of time. A self-heating source must be readily available and must be easily and quickly slipped on to avoid losi...

AI Technical Summary

Benefits of technology

[0011]The warm air derived from the user's exhaled breath is captured into a coupler that fits the mouth of a human, or into an over the nose and mouth face mask, traveling through the mouth piece or mask and into a network of tubing to be delivered to the extremities through the air dispersion holes arrayed along the length of the tubing. The tubing is temporarily fastened to the body extremities by a series of self-adjusting hook and loop fasteners located at various locations along the length of the tubing. This limited attachment allows for an adjustable fit to accommodate a multitude of users of differing heights, weights and body shapes.

[0012]The principal object of the present invention is to provide a portable warm air delivery system for the body that does not require remote sources of heat and allows the user to create the heat from exhaled air, which air temperature is at the approximate core body temperature of 98.6° F., to warm the extremities of the user's body. The warm air delivery system provides a warmed air thermal protective layer between the exterior weather protection garments and the street clothes of the user, which insulates the human from the exterior weather and maintains a heated thermal barrier. This device is designed to be used by any person who spends an extended period of time outside in temperatures of 20° or below.

[0013]Another object of the present invention is to provide a portable warm air delivery system that is relatively simple and inexpensive to manufacture, relatively light weight and comfortable for the user. Still another object of the present invention is to provide a portable warm air delivery system that creates a warmed air thermal protective layer that will insulate a human from any harsh exterior environmental conditions and which fits easily over the user's street clothes and under their outer weather protection clothes in order to maintain a heated thermal barrier. Yet another object of the present invention is to provide a portable warm air delivery system that will remain effective regardless whether the user is standing, sitting, or lying down.
