Patent ID: 7617941

Claim:
A product display rack comprising: a plurality of interlocking modular units, each one of said modular units comprising: a first wire member; a second wire member, wherein said second wire member is parallel to said first wire member in a first horizontal plane located at the bottom of the unit; a third wire member, wherein said third wire member is parallel to said first wire member in a first vertical plane, and wherein further said third wire member is above said first wire member; a fourth wire member, wherein: said fourth wire member is parallel to said third wire member in a second horizontal plane forming the top of the unit; said fourth wire member is parallel to said second wire member in a second vertical plane; said first wire member is connected to said second wire member and said third wire member; said second wire member is connected to said fourth wire member; a first L-shaped flange having a vertical portion and a horizontal portion defining a receiving portion to receive one of the wire members of another one of said modular units, wherein said first L-shaped flange is attached to said first wire member such that the first L-shaped flange extends parallel to the first wire member; a second L-shaped flange having a vertical portion and a horizontal portion defining a receiving portion to receive one of the wire members of another one of said modular units, wherein said second L-shaped flange is attached to said third wire member such that the second L-shaped flange extends parallel to the third wire member, and wherein further the vertical portions of the first and second L-shaped flanges extend towards each other; a third L-shaped flange having a vertical portion and a horizontal portion defining a receiving portion to receive one of the wire members of another one of said modular units, wherein said third L-shaped flange is attached to said third wire member such that the third L-shaped flange extends parallel to the third wire member; a fourth L-shaped flange having a vertical portion and a horizontal portion defining a receiving portion to receive one of the wire members of another one of said modular units, wherein said fourth L-shaped flange is attached to said fourth wire member such that the fourth L-shaped flange extends parallel to the fourth wire member, and wherein further the horizontal portions of the third and fourth L-shaped flanges extends towards each other; and wherein the plurality of modular units comprises at least two of said modular units, wherein the second wire member of a first one of said units is received in the first flange of a second one of said units; and further wherein the fourth wire member of the first unit is received in the second flange of the second unit, thereby interlocking the first and second units in a side-by-side arrangement.
