[0001] The invention relates generally to pavement edging for preventing lawn grass from encroaching on pavements.
[0002] Pavement edging blocks and boarders are well known. They generally consist of a paving stone product which is used to form a decorative edging around a driveway or other paved areas. These block like paving edging devices tend to be heavy and expensive. In more recent times, paving edging devices have been made out of extruded material such as plastic. These extruded edging devices can be quite decorative but often fail to prevent grass from encroaching on to the paved areas.
[0003] The preferred method of edging a lawn adjacent to a paved area is to dig an elongated trench along the lawn adjacent to the paved area. This yields a very attractive and decorative look to the lawn. Unfortunately, grass often encroaches into this trench through root propagation. The trench eventually fills with growing grass requiring the grounds keeper to periodically reform the trench with a spade or hoe. A device which assists in the maintaining the trench type lawn edgings would be of assistance to gardeners.
[0004] The present invention overcomes the disadvantages of the prior art by providing a pavement edging device consisting of an elongated extrusion having a flat bottom portion, and opposite first and second side edges. The extrusion also has a trough formed from first and second spaced apart parallel wall portions extending upwardly from the bottom portion between the first and second side edges. The wall portions have first and second top edges, respectively. The extrusion also has first and second flange portions formed on the bottom adjacent the first and second side edges, respectively. The first and second flange portions extend away from the first and second wall portions, respectively.
[0005] With the foregoing in view, and other advantages as will become apparent to those skilled in the art to which this invention relates as this specification proceeds, the invention is herein described by reference to the accompanying drawings forming a part hereof, which includes a description of the preferred typical embodiment of the principles of the present invention, in which:
