Insulated closure structure and method

Abstract

An enclosure door for an insulated space includes an insulated door member that is hingedly mountable to a door frame of an insulated enclosure. A release latch is attached to the door frame for opening the door member. Further, a protective member is affixed in covering relation to at least a portion of an inner face of the door member and is operable to open the door member upon experiencing an impact thereupon. In a particular embodiment, the protective member is affixed to each of a pair of facing door members, each operable to open both door members upon experiencing an impact thereupon.

What is claimed is:  
     
         1 . A method for making an enclosure door for an insulated space comprising the steps of: 
 providing a first and a second door member for being hingedly mountable to opposite sides of a door frame of an insulated enclosure; and    affixing protective means in covering relation to at least a portion of an inner face of one of the door members, the protective means operable upon release means of the door frame to effect an opening of the first and the second door member upon experiencing an impact thereupon.    
     
     
         2 . The method recited in    claim 1   , further comprising positioning an opening means upon at least one of the door members, the opening means distinct from the protective means and operable upon the release means to effect a door member opening.  
     
     
         3 . The method recited in    claim 1   , wherein the protective means comprises a first and a second protective means, one protective means affixed in covering relation to at least a portion of an inner face of each of the first and the second door member, respectively.  
     
     
         4 . The method recited in    claim 3   , wherein the first and the second protective means are each operable upon the respective door member to effect an opening of both the first and the second door members upon experiencing an impact thereupon.  
     
     
         5 . The method recited in    claim 1   , wherein the protective means comprises a resilient bumper affixed along a lower portion of the door member.  
     
     
         6 . The method recited in    claim 5   , wherein: 
 the door member is hinged along a first side and has a second side opposed to the first side; and    the resilient bumper comprises a sheet of polymeric material having a first edge affixed adjacent the door member first side and a second edge opposed to the first edge affixed to the door member adjacent the second side, the second edge curled under an adjacent portion of the sheet.
