Patent ID: 8720090

Claim:
A readily loadable sign display system comprising: a. two vertical frame members, each of which is elongated in one direction and has a groove running in that direction, said grooves having about the same width, said vertical frame members being held parallel to each other with their grooves facing each other to define one or more tracks which accommodate horizontal frame members; b. a plurality of said horizontal frame members, each of which has a generally rectangular configuration and comprises: i. a generally flat back portion; and ii. two flange portions which extend along two opposite edges of said back portion and are generally perpendicular to said back portion, each of said flange portions carrying a groove which faces the groove of the other flange portion such that said grooves provide parallel tracks for the insertion of a sign panel from one or both of the edges of the back portion that does not carry a flange, iii. said flange portions each having a height above said back portion such that said horizontal frame members can fit within said grooves of said vertical frame members and readily slide along said grooves; and c. an obstruction adapted to be affixed to each end of said tracks defined by said vertical frame members, with the obstructions at one end of said tracks being adapted to be readily removable and the obstructions at the other end being adapted to be semi-permanently attached and non-destructively removed such that their removal requires significantly more effort than the removal of the obstructions at the other end.
