Covering devices with warmer pockets

Abstract

A covering device for a foot, hand or other appendage is provided with at least one floating pocket configured to retain a warming device near a particular region of the appendage, for example the toe region of a foot, while facilitating the flow of air around the warming device to enhance its efficacy.

1 . A sock configured for use with the leg of a user, comprising:
 a main body portion having a first end, a second end and an upper surface; and   a generally rectangular pocket portion configured to retain a heating device and including a top layer, a bottom layer, a first pair of opposing sides, a second pair of opposing sides, and a cavity disposed between the top and bottom layers, the first pair of opposing sides, and the second pair of opposing sides, wherein at least a portion of the first pair of opposing sides of the pocket portion are fixed to the main body portion and a substantial portion of the second pair of opposing sides of the pocket portion are separate from the main body portion to facilitate the movement of air between the bottom layer of the pocket portion and the upper surface of the main body portion.   
   
   
       2 . The sock of  claim 1 , wherein the second end of the main body portion corresponds to a toe region of the sock and the pocket portion is attached to the main body portion near the second end. 
   
   
       3 . The sock of  claim 1 , wherein the first end of the main body portion includes an opening and an elastic ribbed portion. 
   
   
       4 . The sock of  claim 1 , wherein the top and bottom layers of the pocket portion are formed of a single layer of material folded over itself so that the first pair of opposing sides includes the fold on one side and overlapped top and bottom layers on the second side. 
   
   
       5 . The sock of  claim 4 , wherein the bottom layer along the second side of the first pair of opposing sides is substantially fixed to the main portion of the sock and at least a portion of the top layer along the second side of the first pair of opposing sides is substantially unattached to the bottom layer to form an opening to the cavity along the second side of the first pair of opposing sides. 
   
   
       6 . The sock of  claim 1 , wherein the top and bottom layers of the pocket portion are formed of a single layer of material folded over itself so that the second pair of opposing sides includes the fold on one side and overlapped top and bottom layers on the second side. 
   
   
       7 . The sock of  claim 6 , wherein the second side of the second pair of opposing sides forms an opening to the cavity. 
   
   
       8 . The covering device of  claim 6 , at least one of the sides in the first pair of opposing sides forms an opening to the cavity. 
   
   
       9 . A covering device configured for use with the appendage of a user, comprising:
 a main body portion having a first end, a second end and an upper surface; and   a pocket portion configured to retain a heating device and including a top layer, a bottom layer and a cavity disposed between the top and bottom layers, wherein the pocket portion is attached to the main body portion such that air is generally permitted to flow between the bottom layer of the pocket portion and the upper surface of the main body portion.   
   
   
       10 . The covering device of  claim 9 , wherein the main body portion comprises a sock. 
   
   
       11 . The covering device of  claim 10 , wherein the second end of the main body portion corresponds to a toe region of the sock and the pocket portion is attached to the main body portion near the second end. 
   
   
       12 . The covering device of  claim 9 , wherein the top and bottom layers of the pocket portion are formed of a single layer of material folded over itself so that the cavity includes four sides, one being bound by the fold and the other three being at least partially closed. 
   
   
       13 . The covering device of  claim 12 , wherein two of the three partially closed sides are stitched to the main body portion of the covering device. 
   
   
       14 . The covering device of  claim 9 , wherein the main body portion comprises first and second sides and the pocket portion comprises first and second unattached sides and first and second attached sides, at least a portion of the first and second attached sides of the pocket portion being attached to the main body portion along a portion of the first and second sides of the main body portion. 
   
   
       15 . The covering device of  claim 14 , wherein the pocket portion is stitched to the main body portion. 
   
   
       16 . The covering device of  claim 14 , wherein access to the cavity is permitted through one of the first and second unattached sides of the pocket portion. 
   
   
       17 . The covering device of  claim 14 , wherein access to the cavity is permitted through one of the first and second attached sides of the pocket portion. 
   
   
       18 . The covering device of  claim 9 , wherein access to the cavity is permitted through a selectively closable opening. 
   
   
       19 . The covering device of  claim 18 , wherein the selectively closable opening includes a button to selectively secure the top and bottom layers of the pocket portion to each other near the opening. 
   
   
       20 . The covering device of  claim 18 , wherein the selectively closable opening includes a hook and loop type fastener to selectively secure the top and bottom layers of the pocket portion to each other near the opening.
