Cooling linings

Abstract

A cooling lining comprises an outer ( 116 ) and inner layer ( 118 ) for example of woven material. On the inner layer are a number of pockets ( 120 ) with air channels forming a lattice there between. Within each pocket is a support member ( 130 ) with an insulation member ( 128 ) nearer the front face of the pocket to hold the sides of the pocket taut or substantially taut. Hydrophilic material ( 134 ) is inserted into the pockets. The lining may form a cooling vest ( 100 ) or may comprise separate members that can be attached to inside of a flak jacket by Velcro strips.

1 . A cooling lining comprising a outer member, pockets mounted on the inner side of the outer member wherein spaces are provided between pockets and the pockets are arranged to cool the air in the said spaces. 
     
     
         2 . A cooling lining as claimed in  claim 1  wherein some of the spaces are arranged to form continuous channels which can guide hot air away from the liner. 
     
     
         3 . A cooling lining as claimed in  claim 2  wherein outwardly directed spaces and transfer spaces are provided between the pockets arranged to conduct air to the continuous channels. 
     
     
         4 . A cooling lining as claimed in  claim 1  wherein the inner surface of each pocket comprises insulation material. 
     
     
         5 . A cooling lining as claimed in  claim 1  wherein an insulating material is placed against the inner surface of each pocket. 
     
     
         6 . A cooling lining as claimed in  claim 4  wherein the outer member also has insulating properties. 
     
     
         7 . A cooling lining as claimed in  claim 1  wherein the outer member is fireproof. 
     
     
         8 . A cooling lining as claimed in  claim 1  wherein the side surfaces of the pocket are permeable to water. 
     
     
         9 . A cooling lining as claimed in  claim 8  further comprising hydrophillic material within the pockets. 
     
     
         10 . A cooling lining as claimed in  claim 1  wherein the inner surface comprises moulded material and the pockets are moulded from the said moulded material. 
     
     
         11 . A cooling lining as claimed in  claim 10  wherein the moulded material comprises polyethylene. 
     
     
         12 . A cooling lining as claimed in  claim 1  wherein the outer member comprises woven material. 
     
     
         13 . A cooling lining as claimed in  claim 12  wherein each of the pockets is stitched on to the inner side of the outer member. 
     
     
         14 . A cooling lining as claimed in  claim 12  wherein the woven material is cotton. 
     
     
         15 . A cooling lining as claimed in  claim 1  wherein the walls of the pockets are kept taut or predominantly taut by support means within the pocket. 
     
     
         16 . A cooling lining as claimed in  claim 15  wherein the support means comprises a central part which is of smaller size than the pocket and is located within the pocket. 
     
     
         17 . A cooling lining as claimed in  claim 15  wherein a surrounding space surrounds the central part within the pocket surrounding the central part. 
     
     
         18 . A cooling lining as claimed in  claim 17  wherein hydrophillic substance is packed in to the surrounding space. 
     
     
         19 . A cooling lining as claimed in  claim 1  in the form of an article of clothing. 
     
     
         20 . A cooling lining as claimed in  claim 19  wherein the article of clothing comprises a cooling vest. 
     
     
         21 . A cooling vest as claimed in  claim 20  wherein the outer member has symmetrical or predominantly symmetrical front and back portions and lateral portions connecting the front and back portions to hold the front and back portions firmly on to the torso of the wearer's body. 
     
     
         22 . A cooling vest as claimed in  claim 21  wherein the front and back portions may have connecting means capable of releasably holding the linings on the wearers body. 
     
     
         23 . A cooling vest as claimed in  claim 22  wherein the connecting means comprise mechanical fastening means. 
     
     
         24 . A cooling vest as claimed in  claim 23  wherein the mechanical fastening means are selected from the group comprising zips, buttons and press studs. 
     
     
         25 . A cooling vest as claimed in  claim 21  wherein at least one space defining a convection channel runs the majority of the vertical length of the front and rear portion of the cooling vest.
