Title: Door check and hold-open device

Abstract: A door check having a slidable arm mounted on a multi-stepped shoulder fastener has means for pivotally mounting the arm on the door of a refrigerator display case or like apparatus at one end thereof and has an elongated slot extending from the mid portion of the arm to an opposite end thereof which receives the shoulder fastener. A restriction is provided in the slot near the outer end thereof. The fastener is mounted on the display case and engages the outer end of the slot when the door of the display case is swung to the full open position. The hold the door open the arm can be moved upwardly so that the restriction in the slot bears against an enlarged shoulder of the multi-stepped fastener to retain the door in the open position. Pressure on the door toward the closed position spreads the restriction in the slot apart to drop the arm and permit travel of the door to the closed position without damage to the door stop. In the alternative, pressure on the door toward the open position disengages the enlarged shoulder from the restriction and allows the arm to drop back to its normal position so as to permit travel of the door.
