Abstract
Abstract A dual-purpose lawn edging device which serves as a grass stop and a track for a lawn mower wheel. The device has a main strip and at least one side wall extending upwardly from one side edge of the strip with the side wall having a top ridge and an extension which extends downwardly from the ridge to define a supporting leg for the device which is adapted to be embedded in the ground to hold the device in position. The main strip is sufficiently wide to define the track and the side wall serves as a guide for the wheel while allowing easy crossing thereover.

Total Claims: 11
Claim 1
Independent Claim
155 words
A dual-purpose lawn edging device serving as a grass stop and a track for a lawn mower wheel, said device comprising, a main strip, a side wall extending upwardly from one side edge of said strip, with said side wall having a top ridge, an extension which extends downwardly from said ridge to define a supporting leg for said device which is adapted to be embedded in the ground to hold said device in position, and integral gusset means provided in said strip enabling bending of said strip in an arcuate path which is substantially coplanar with the plane of said strip and enabling arranging said device in an arcuate path, said gusset means being free of openings thereby preventing grass from growing therethrough, said strip being sufficiently wide to define said track and said side wall serving as a guide for said lawn mower wheel yet enabling comparatively easy crossing of said wheel thereover.

Claim 6
Dependent Claim
226 words
A dual-purpose lawn edging device serving as a grass stop and a track for a lawn mower wheel, said device comprising, a main strip, a first and a second side wall extending upwardly from opposite side edges of said strip with each of said side walls having a top ridge, an extension which extends downwardly from each ridge to define a pair of supporting legs on opposite sides of said device which are adapted to be embedded in the ground to hold said device in position, and integral gusset means provided in said strip enabling bending of said strip in an arcuate path which is substantially coplanar with the plane of said strip and enabling arranging said device in an arcuate path, said gusset means being free of openings, said strip being sufficiently wide to define said track, said first side wall having a given height above said strip and serving as a guide for said lawn mower wheel yet enabling comparatively easy crossing of said wheel thereover, said second side wall having a height above said main strip which is greater than said given height and said second side wall serving as a stop to prevent easy crossing of said wheel thereover, whereby said device has a guide for said wheel along one side thereof and a stop for said wheel along its opposite side.
