  • Patent number: 6823689
    Abstract: A fastening device for an ice maker of a refrigerator is provided which improves ease and efficiency of installation is provided. Mounting brackets formed along a side of the ice maker each include an insertion portion formed as an opening in the mounting bracket, and a catching portion formed as an opening adjacent to the insertion portion and with a smaller width than that of the insertion portion. Hangers having a large diameter portion and a small diameter portion are affixed to the wall of the freezing chamber by a fastener, and the mounting brackets are slid onto the hangers until the small diameter portion of the hanger is caught in the catching section of the mounting bracket. The ice maker may be further secured by additional fixing brackets opposite the mounting brackets. This fastening device allows the ice maker to be more easily installed while also minimizing the potential for damage to the brackets or the wall surface of the freezer during installation.
