Abstract: A door-operating mechanism is disclosed which is particularly suited for use with hingedly mounted swinging glass doors of a refrigerated display cabinet. The door operating mechanism includes an extensible gas spring biased toward an extended condition, and a linkage arrangement operatively interconnecting the gas spring with the door. A portion of the gas spring is movably disposed within a slot defined by the linkage arrangement such that in one position of the gas spring the door is biased toward its closed position, and in another position of the gas spring the door may be maintained in an opened position such as for stocking or maintenance of the display cabinet.

Abstract: An improved adjustable mounting arrangement for mounting a glass door assembly on a door frame for a refrigerated display cabinet. The mounting arrangement includes upper and lower hinge assemblies for providing swinging movement of the door assembly relative to the door frame, with the hinge assembly accommodating adjustment of the hinge axis relative to the door frame for alignment of the door assembly in order to provide effective sealing and enhanced appearance of the display case. The hinge assemblies include upper and lower hinge brackets which are adapted to receive upper and lower hinge pins of the door assembly, the brackets being adapted to be attached to frame members of the door frame in different positions for effecting alignment of the door.
