Patent ID: 7621223

Claim:
A shelf system for corner walls, comprising: A) a substantially flat shelf member having at least two contiguous sides defining first and second edges of a predetermined thickness and perpendicular to each other, said first and second edges each including at least one tongue member that extends coplanarly outwardly a predetermined distance, said at least one tongue member having a slightly smaller thickness than said first and second edges thereby defining a step between said shelf member and said tongue member, B) a corner wall having first and second walls perpendicular to each other and said first and second walls including in each of said first and second walls at least one cavity for each of said at least one tongue member, and each of said at least one cavity being cooperatively located to receive one of said tongue members and each of said at least one cavity including an opening through which said tongue member passes and is snuggly received within said cavity, one of the cavities on one of said first wall or second wall having cooperative dimensions to permit lateral movement of said tongue member within said cavity where said tongue member is first inserted; and C) adhesive means applied to said first and second edges and to said at least one tongue member for rigid affixation of said shelf member to said first and second walls respectively, upon contact preventing lateral movement of said shelf member to insure the tongue member and said at least one cavity stay engaged; so that said shelf member is capable of supporting loads of a predetermined magnitude.
