Abstract:
1. Interlocking attachment surfaces, releasably connectable one to another in a face to face orientation, the attachment surfaces comprising: a first attachment surface comprising a plurality of parallel spaced ridge pairs, each ridge pair comprising parallel first and second ridge walls having single, pointed, outward oriented ridge wall edges, and a turret ridge parallel to and positioned between the first and second ridge walls; and a second attachment surface comprising a plurality of parallel spaced post-based ridges, each post-based ridge comprising a ridge wall having a cap with two, pointed, outward oriented cap edges; wherein two adjacent parallel spaced ridge pairs of the first attachment surface define a corresponding first longitudinal channel between the pairs, and the parallel first and second ridge walls of each parallel spaced ridge pair define a second longitudinal channel between the ridge walls, the longitudinal channels each having a depth, and wherein each turret ridge positioned between first and second ridge walls comprises a longitudinal blocking turret having a height approximately equal to or greater than the depth of the second longitudinal channel, and wherein a post-based ridge of the second attachment surface aligns with and intrudes into the corresponding first longitudinal channel but is prevented from intruding into the second longitudinal channel by the turret ridge therein.
