A ground dividing edging for bordering a lawn area from an adjacent ground area comprising, a plurality of contiguous flat base members adapted to be laid on the surface of the ground for forming an outline of the ground area which is to be divided from the lawn area, and a plurality of contiguous cap members each having a substantially vertical retaining wall portion and a substantially horizontal supporting surface portion, each of said plurality of said cap members disposed atop said flat base members wherein said cap members and said flat members include interlocking means which permit said cap members to be detachably secured to said flat members.
Claim 3
Dependent Claim
24 words
A ground dividing edging as defined in claim 1, wherein said flat base members are rigidly fastened to the ground by ground retaining members.
Claim 4
Dependent Claim
36 words
A ground dividing edging as defined in claim 1, wherein said flat base members include cutout portions which minimize heaving misalignment during periods of freezing and thawing and prevent water fRom accumulating on the base member.
