Lawn edging
First Claim
1. A lawn edging for use in demarcating a lawn having a plurality of paving stones, the lawn edging comprising:
- an elongated extrusion made of a flexible and resilient polymer, the extrusion having opposite ends;
the extrusion having a bottom, first and second side walls extending from the bottom and a transverse cross brace extending between and the side walls and connecting the side walls together;
the bottom having a toe portion extending perpendicularly from the first wall, the toe portion being dimensioned and configured to fit beneath the paving stones;
the first wall being divided into an upper portion above the transverse cross brace and a lower portion between the transverse cross brace and the toe portion, the lower portion being perpendicular with respect to the toe portion, the upper portion of the first wall being at an obtuse angle to the lower portion such that the upper portion extends away from the lower portion of the side wall and away from the second side wall, the upper portion being configured to be sufficiently flexible and resilient such that when the first side wall is urged against the paving stones the upper portion of the first side wall is deflected to be substantially co-planar to the lower portion of the first side wall and the upper portion is biased against the paving stone.

Abstract
The present invention is a lawn edging for demarcating a lawn from a border consisting of paving stones, the lawn edging consisting of an elongated extrusion made of a flexible and resilient polymer, the extrusion having opposite ends. The extrusion has a bottom, first and second side walls extending from the bottom and a transverse cross brace extending between and the side walls and connecting the side walls together. The bottom has a toe portion extending perpendicularly from the first wall, the toe portion being dimensioned and configured to fit beneath the paving stones. The first wall is divided into an upper portion above the transverse cross brace and a lower portion between the transverse cross brace and the toe portion, the lower portion being perpendicular with respect to the toe portion. The upper portion of the first wall is at an obtuse angle to the lower portion such that the upper portion extends away from the lower portion of the side wall and away from the second side wall. The upper portion is configured to be sufficiently flexible and resilient such that when the first side wall is urged against the paving stones the upper portion of the first side wall is deflected to be substantially co-planar to the lower portion of the first side wall and the upper portion is biased against the paving stone. The extrusion has an open top defined by the upper portion of the first and second walls which flare out relative to lower portions of the first and second walls.

3. A lawn edging for use in demarcating a lawn having a plurality of paving stones, the paving stones having a height, the lawn edging comprising:
-
an elongated extrusion made of a flexible and resilient polymer, the extrusion having opposite ends; the extrusion having a bottom, first and second side walls extending from the bottom, and a transverse cross brace extending between and the side walls and connecting the side walls together, the first and second walls each being divided into an upper portion above the transverse cross brace and a lower portion between the transverse cross brace and the toe portion; the extrusion having an open top defined by the upper portions of the first and second walls and the transverse cross brace, the extrusion having a lower diameter defined by the distance between the lower portions of the first and second walls and an upper diameter defined by the distance between the upper first and second walls, the upper diameter being greater than the lower diameter; the bottom having a toe portion extending perpendicularly from the first wall, the toe portion being dimensioned and configured to fit beneath the paving stones; the upper portion of the first wall being at an obtuse angle to the lower portion such that the upper portion extends away from the lower portion of the side wall and away from the second side wall, the upper portion being configured to be sufficiently flexible and resilient such that when the first side wall is urged against the paving stones the upper portion of the first side wall is deflected to be substantially co-planar to the lower portion of the first side wall and the upper portion is biased against the paving stone. - View Dependent Claims (4, 5, 6, 7, 8)
