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.
