CLOSING SYSTEM FOR COLD ROOMS

摘要

This system is comprised of an insulated access door (6), which makes for the closure of the cold room (4) in coming into contact with the door frame (1) fixed onto the entrance (2) of said cold room (4), and a quick opening door made up of a moveable sheet (8) and the corresponding means of activation (9, 10). These means of activation are to be fixed to the exterior of the cold room (4). There is also a longitudinal slit (7) fixed onto the door frame (1) so that the sheet (8) can pass, this sheet (8) being able to effect the closure either in front of or behind the insulated door (6). The system includes a stopper device (7) which can close the slit (7) in order to minimise the temperature loss through same, and some means (71 and 161) of heating the slit (7) and some guides (16) on which the sheet (8) moves to its open or closed position. <IMAGE>
