Patent ID: 8529000

Claim:
A shelf assembly for a refrigerator, comprising: a supporting plate; an upper frame enclosing an upper part of a peripheral edge of the supporting plate and including an upper groove spaced apart from the peripheral edge of the supporting plate; a lower frame enclosing a lower part of the peripheral edge of the supporting plate and including a lower groove spaced apart from the peripheral edge of the supporting plate; and a sealing member receiving part generated by the upper and the lower grooves as the upper and the lower frames are interconnected, thereby receiving the peripheral edge of the supporting plate, wherein the supporting plate and the upper and the lower frames are fusion-bonded to one another, the sealing member receiving part receives a sealing member sealed and bonded to the supporting plate, and at least one of the upper frame and the lower frame, wherein the lower groove is formed as a recessed groove between a lower supporting stage and a stepped stage, the lower supporting stage being extended upward from an interior of an upper surface of the lower frame to support a first side of the supporting plate and the stepped stage being disposed at a predetermined interval from the lower supporting stage and stepped at an outer part of the upper surface of the lower frame, and the upper groove is formed as a recessed groove between an upper supporting stage and an upper sealing member leakage prevention stage, the upper supporting stage being extended downward from an interior of a lower surface of the upper frame to support a second side of the supporting plate opposite the first side, and the upper sealing member leakage prevention stage being disposed at a predetermined interval from the upper supporting stage and extended from an outer part of the lower surface of the upper frame toward the stepped stage to be fusion-bonded with the lower frame.
