    摘要: A connection surface that is disposed on at least a portion of a face of a structural unit comprises a first convex surface and a first concave surface arranged substantially along a first line. The shape of the first concave surface is complementary to the shape of the first convex surface. A second convex surface and a second concave surface are arranged substantially along a second line that is substantially parallel to the first line. The shape of the second concave surface is complementary to the shape of the second convex surface. The concave-convex order of the second line is reversed relative to the first line, such that the second convex surface corresponds with the first concave surface and the second concave surface corresponds with the first convex surface.

    摘要: A garden edging system is made up of (a) one or more straight edger units, (b) one or more curved edger units and (c) one or more corner units. Each unit has a connecting face at each of its ends for connecting and holding adjacent units in end-to-end alignment with one another. The connecting faces facilitate the layout of a myriad of garden edging designs. The curved units have both their convex side and their concave side formed on the same arc of curvature so that a plurality of the units may be nested together with the concave side of each unit engaged flush against the convex side of the next adjacent unit. This facilitates packing and shipping of the units and mitigates against damage to the units. The units are dimensioned and sized to be stronger, more damage resistant, more versatile and more user-friendly than conventional edger bricks or tiles. A process of making the edger units is also disclosed.
