Patent ID: 7350648

Claim:
A modular display system comprising a plurality of display modules which can be assembled together, each said module comprising: a vertical mounting surface lying in a mounting plane; a pair of parallel sidewalls having opposed outside surfaces lying in side planes extending forward from said mounting plane at right angles to the mounting plane; a bottom surface lying in a bottom plane extending forward from said mounting plane at right angles to said mounting plane and said sidewalls; and a top surface lying in a top plane extending forward from said mounting plane at right angles to the mounting plane and the side planes; a pair of top rails lying above said top plane, each said top rail having an inner surface which faces said top plane to form a channel, said channels facing respective said side planes; and a pair of bottom rails extending inward from respective said sidewalls above said bottom plane, each said bottom rail having an inner surface which faces away from the bottom plane; wherein said inner surfaces of the bottom rails converge toward the bottom plane at an acute angle, whereby said inner surfaces of said top rails of one module are received against said inner surfaces of said bottom rails of another module in a press fit when said top surface of said one module is received against said bottom surface of said another module and said modules are slid together until their mounting planes are substantially coplanar.
