Blo-warm vest

Abstract

A garment including a one-way inlet line connected to a chamber formed by at least a portion of the front and back of the garment. The line extends through a portion of the garment to a designated location where warm air from the user's breath is distributed in the chamber. There is a second valve that the user operates to release the contained air, such as when one goes inside or when one wants to replenish the warm air after a period of time has passed.

1 . A garment device for providing warmth to a user in a cold environment, comprising:
 a chamber formed by at least a portion of the front and back of the garment;   an inlet line having an open end proximate the user's mouth and positioned for receipt of the user's breath, the line extending into the chamber to a designated location where the user's breath is distributed in the chamber;   a release valve in communication with the chamber and operable to maintain the chamber in a closed condition holding the user's breath therein and an open condition to release the user's breath when desired by the user.   
   
   
       2 . The device of  claim 1 , wherein the inlet line includes a check valve inside the chamber to prevent flow of air back out the open end of the inlet line. 
   
   
       3 . The device of  claim 1 , wherein the chamber is formed from an air and water impermeable material. 
   
   
       4 . The device of  claim 1 , wherein the garment includes a front portion and back portion that are joined together to form the chamber. 
   
   
       5 . The device of  claim 1 , wherein the inlet line includes a plurality of holes in at least the portion of the inlet line between the check valve and the release valve. 
   
   
       6 . The device of  claim 1 , wherein the inlet line further extends from the release valve to a to a release point proximate the user's back. 
   
   
       7 . The device of  claim 1 , wherein the garment is sized to be worn under other garments. 
   
   
       8 . A method for providing a garment to provide warmth to a user in a cold environment, comprising the steps of:
 forming a chamber by at least a portion of the front and back of the garment;   providing an inlet line having an open end proximate the user's mouth and positioned for receipt of the user's breath, the line being positioned to extend into the chamber to a designated location where the user's breath is distributed in the chamber; and   providing a release valve in communication with the chamber and operable to maintain the chamber in a closed condition holding the user's breath therein and an open condition to release the user's breath when desired by the user.   
   
   
       9 . The method of  claim 8 , wherein the inlet line includes a check valve inside the chamber to prevent flow of air back out the open end of the inlet line. 
   
   
       10 . The method of  claim 8 , wherein the chamber is formed from an air and water impermeable material. 
   
   
       11 . The method of  claim 8 , wherein the garment includes a front portion and back portion that are joined together to form the chamber. 
   
   
       12 . The method of  claim 8 , wherein the inlet line includes a plurality of holes in at least the portion of the inlet line between the check valve and the release valve. 
   
   
       13 . The method of  claim 8 , wherein the inlet line further extends from the release valve to a to a release point proximate the user's back. 
   
   
       14 . The method of  claim 8 , wherein the garment is sized to be worn under other garments. 
   
   
       15 . In a garment device for providing warmth to a user in a cold environment wherein the garment has a front and back portion, the improvement comprising:
 forming a chamber from at least a portion of the front and back of the garment;   positioning an inlet line having an open end proximate the user's mouth and positioned for receipt of the user's breath, the line extending into the chamber to a designated location where the user's breath is distributed in the chamber; and   placing a release valve in communication with the chamber and operable to maintain the chamber in a closed condition holding the user's breath therein and an open condition to release the user's breath when desired by the user.   
   
   
       16 . The device of  claim 15 , wherein the inlet line includes a check valve inside the chamber to prevent flow of air back out the open end of the inlet line. 
   
   
       17 . The device of  claim 15 , wherein the chamber is formed from an air and water impermeable material. 
   
   
       18 . The device of  claim 15 , wherein the garment includes a front portion and back portion that are joined together to form the chamber. 
   
   
       19 . The device of  claim 15 , wherein the inlet line further extends from the release valve to a to a release point proximate the user's back. 
   
   
       20 . 5. The device of  claim 15 , wherein the inlet line includes a plurality of holes in at least the portion of the inlet line downstream of the check valve.
