An interlocking structure comprises a plurality of frame members having longitudinally extending channels formed therein. The channels have opposed overhanging lips defining an entrance for the channels that is narrower than an interior portion thereof. The channels are of similar dimensions and are adapted to be placed in opposing relationship. Bridging members are adapted to be fitted into opposed pairs of channels so as to hold together the adjacent frame members in which the opposed pair of channels are formed. |
