Abstract
A hold-open mechanism is disclosed which is particularly suitable for use on a self-closing door assembly for a refrigerated display cabinet. The hold-open mechanism includes a stop plate carried by the hinged door, and a hold-open spring mounted on the door frame which supports the door. In one embodiment, the hold-open spring is selectively positionable so as to accommodate normal swinging movement of the door in one position, and is adapted to releasably engage and retain the stop plate on the door in a second position so that the door is maintained opened. In another embodiment, the hold-open mechanism automatically operates to releasably retain the door in its fully opened position whenever the door is moved to that position.
