Abstract
A device for automatically holding a refrigerator door releasably in a fully open position relative to a refrigerated display cabinet. The device includes an elongated spring arm connected pivotally to a frame member of the cabinet and formed with an elongated slot which receives a pin connected to a frame member of the door. The pin slides in the slot and causes the arm to pivot outwardly as the door is swung open. As the door approaches its fully open position, the pin cams past detent lugs in the slot and then engages the lugs to prevent the door from closing unless the door is swung closed with sufficient force to cause the pin to cam reversely past the detent lugs.
