Abstract

An open bottomed trapezoidal box having horizontally outwardly extending flanges at the free edges is provided at intervals with clips which join the horizontal flanges and which join successive lengths of the linear open box sections. The linear sections may be straight, curved on one or more radii, or angular, for flexibility in forming any outline. Alternate embodiments of the clip are shown. The clip may be used in straight lengths whether the sections are curved, angular, or straight.

Claims

1. A lawn edging comprising linear box sections having a top wall and two side walls wherein the novelty comprises side walls that are straight in lateral cross-section and inclined between about 10°

and 30°

to a vertical plane to form an isosceles trapezoid with said top wall and an underlying surface, outwardly directed flanges at the bottom of each side wall, and a plurality of clips, each said clip having an inwardly directed channel at each end to receive a said outwardly directed flange and an outwardly directed abutment engageable with the inner margin of the flange to retain the flange in the channel.

2. The device of claim 1 wherein the abutment is a flange projecting from the surface of the clip.

3. The device of claim 1 wherein the clip has a generally flat bottom surface connecting the flanges, and is very limited in length in a direction along the edging.

4. The device of claim 3 wherein said abutment is an offset in said generally flat bottom surface.

5. The device of claim 1 wherein said top wall is joined to said side walls by a straight edge.

6. The device of claim 1 where said top wall is joined to said side walls by a curved edge.

7. The device of claim 1 wherein said top wall is joined to said side walls by an angular edge.

8. The device of claim 1 wherein the clip has a generally flat bottom surface connecting the flanges, and is very limited in length in a direction along the edging, and said abutment is an offset in said generally flat bottom surface and said top wall is connected to each of said side walls along a linear edge.
