Abstract

A warm air mask comprising a facial covering configured to form an upper edge positionable above the nose of a wearer, a lower edge positionable beneath the chin of a wearer, and side edges positionable beyond the ears of a wearer; a plurality of oval inhale ports formed in the covering and extending therethrough, each inhale port including a flap to open with the inhaling of a wearer and to close with the exhaling of a wearer. An exhale port is formed in the covering and extending therethrough, the exhale port including a flap to open with the exhaling of a wearer and to close with the inhaling of a wearer. Further, an array of electrical resistance wires for generating heat when electrically activated, the array being positioned in each inhale port with an associated electrical power source for selectively activating and inactivating the resistance wires.

Claims

1. A new and improved warm air mask comprising, in combination:

a facial covering positionable over the mouth, nose, chin and cheeks of a wearer, the covering including an interior layer of a stay dry material, an exterior layer of a stay dry material and an intermediate layer of felt therebetween, the covering configured to form an upper edge positionable above the nose of a wearer, a lower edge positionable beneath the chin of a wearer, and side edges positionable beyond the ears of a wearer;

three oval inhale ports formed in the covering and extending therethrough, each inhale port including a fabric mesh and an imperforate flexible flap to open with the inhaling of a wearer and to close with the exhaling of a wearer;

a single circular exhale port formed centrally in the covering and extending therethrough, the exhale port including an imperforate flexible flap to open with the exhaling of a wearer and to close with the inhaling of a wearer;

an array of electrical resistance wires for generating heat when electrically activated, the wires of the array being positioned in each inhale port with an associated electrical power source and a switch secured adjacent to the covering for selectively activating and inactivating the resistance wires;

a pair of parallel securement straps having first ends fixedly secured to one edge of the covering and second ends separably secured to the other edge of the covering;

pile type fasteners releasably securing the other edge of the covering to the second ends of the straps; and

adjustment members located on the straps intermediate the ends.

2. A warm air mask comprising, in combination:

a facial covering configured to form an upper edge positionable above the nose of a wearer, a lower edge positionable beneath the chin of a wearer, and side edges positionable beyond the ears of a wearer;

a plurality of oval inhale ports formed in the covering and extending therethrough, each inhale port including a flap to open with the inhaling of a wearer and to close with the exhaling of a wearer;

an exhale port formed in the covering and extending therethrough, the exhale port including a flap to open with the exhaling of a wearer and to close with the inhaling of a wearer; and

an array of electrical resistance wires for generating heat when electrically activated, the array being positioned in each inhale port with an associated electrical power source for selectively activating and inactivating the resistance wires.

3. The device as set forth in claim 2 and further including:

a pair of parallel securement straps having first ends fixedly secured to one edge of the covering and second ends separably secured to the other edge of the covering.

4. The device as set forth in claim 3 and further including:

pile type fasteners releasably securing the other edge of the covering to the second ends of the straps.

5. The device as set forth in claim 3 and further including:

adjustment members located on the straps intermediate the ends.
