DOOR HINGE DEVICE FOR A REPOSITORY

摘要

A door hinge device comprises a door support member and a door mounting member. The door support member is provided with a tongue, and is attached to a refrigerator housing. The door mounting member is attached to a door, and is provided with a second coupling portion connected to the tongue. A shaft and a guide pin stand on the tongue, and each is loosely fitted with a cylindrical collar. The door mounting member is provided with a shaft fitting slot which extends along the depth of the refrigerator housing when the door is closed, and the shaft is fitted in the shaft fitting slot. A guide recess is formed at the rear portion of the second coupling portion to engage the guide pin. The guide recess and the guide pin jointly move the shaft along the shaft fitting slot when the door is located near the position to close an opening of the refrigerator housing, and rocks the shaft relative to the shaft fitting slot until a given angle is formed between the door and the refrigerator housing when the door is kept away from the position to close the opening.
