20120085502 | AIR HEATED, FLEXIBLE DOOR PANEL - A door system for a cold storage locker includes resilient door panels that flex and have increased resistance to damage when hit by a forklift. A high degree of insulation is achieved by the choice and thickness of the resilient foams therein. Also, the resilient door panels are magnetically attracted to a gasket seal on a doorframe to provide an affirmative seal. Active magnetic control may enhance the attraction or repulsion of the door panel. Frost control is realized by warming air from the cold storage locker and passing it through air channels in the door panel proximate to the gasket seal and down an astragal interface between door panels. Door panels of laminate, bagged poured foam formation, and self-skinning foam formation further reduce the cost of manufacture and shipping. | 04-12-2012 |
