Abstract

A lawn and garden edging device is provided for serial coupling to form both linear and angled segments for defining lawn and garden boundaries and isolating building structures from the same. A center base portion has reduced thickness end portions with pivoting snap fit connections for mating at both ends with like devices to form a smooth and uniform horizontal base segment that can lie flush or at angles to the horizontal ground surface. A back plate of varying configurations is attached to the base center portion for insertion into the soil to form a vertical sub-surface wall for both straight and cornered configurations. One or more spikes extending from the horizontal base doubly secures the device installation. A vertical back plate is positioned on the device for an above surface wall. The vertical back plate has brackets and an extension for connecting the vertical back plates in series.

Claims

1. A lawn edging device, comprising:

a first elongated member having;

a center portion having an edge;

a first end portion and a second end portion, each extending from the center portion, the first end portion being attachable to the second end portion of a like device, the second end portion being attachable to the first end portion of a like device, the first and second end portions being sized such that, when attached, the combined thicknesses of the first end portion and the second end portion of the like device are substantially the same as the thickness of the center portion;

a second elongated member having an edge, the second elongated member being attached to the first elongated member such that the first and second elongated members form a vertex at the attached edges;

third elongated member, the third elongated member having an edge and being attached to the first elongated member edge such that the second and third elongated members lie in the same or substantially parallel planes; and

an extension member extending from the third elongated member; and

first and second brackets positioned on the third elongated member for closely receiving the extension member of a like device such that the third elongated member is joined to the third elongated member of the like device.

2. The device of claim 1, further comprising a spike, the spike being downwardly disposed and attached to the first elongated member.

3. The device of claim 2, wherein the spike has a threaded member and the first elongated member has a threaded aperture, the spike threaded member being matable with the first elongated member threaded aperture.

4. The device of claim 2, wherein the spike has a threaded aperture and the first elongated member has a threaded member, the spike threaded aperture being matable with the first elongated member threaded member.

5. The device of claim 1, further comprising a plurality of spikes, the spikes being downwardly disposed and attached to the first elongated member.

6. The device of claim 1, wherein the second elongated member extends along the combined lengths of the center portion and the first end portion.

7. The device of claim 1, wherein the second elongated member extends along the combined lengths of the center portion and the second end portion.

8. The device of claim 1, wherein the second elongated member extends along the combined lengths of the center portion, the first end portion, and the second end portion.

9. The device of claim 1, wherein the extension member is flexible.

10. The device of claim 1, wherein the extension member is offset from the third elongated member such that the extension member is linearly aligned with the first and second brackets.

11. The device of claim 1, wherein the first end portion is semi-circular in the plane of the first elongated member.

12. The device of claim 11, wherein the center portion extends over the second end portion, the center portion extension being arcuately shaped to closely receive the semi-circular first end portion of a like device.

13. The device of claim 1, wherein the second end portion is semi-circular in the plane of the first elongated member.

14. The device of claim 1, wherein the first and second end portions are semi-circular in the plane of the first elongated member.

15. The device of claim 1, wherein the first end portion further comprises a male locking extension and the second end portion comprises a female receptacle, the female receptacle being shaped for receiving and securing the male locking extension on the first end portion of a like device.

16. A lawn edging device, comprising:

a first elongated member having;

a center portion having an edge;

a first end portion and a second end portion, each extending from the center portion, the first end portion being attachable to the second end portion of a like device, the second end portion being attachable to the first end portion of a like device, the first and second end portions being sized such that, when attached, the combined thicknesses of the first end portion and the second end portion of the

like device are substantially the same as the thickness of the center portion;

a second elongated member attached to the first elongated member such that the plane of the first elongated member is transverse to the plane of the second elongated member; and

an extension member extending from the second elongated member; and

first and second brackets positioned on a third elongated member for closely receiving the extension member of a like device such that the second elongated member is joined to the second elongated member of the like device.

17. The device of claim 16, wherein the extension member is flexible.

18. The device of claim 17, wherein the extension member is offset from the second elongated member such that the extension member is linearly aligned with the first and second brackets.

19. A lawn edging device, comprising:

a first elongated member having;

a center portion having an edge;

a first end portion and a second end portion, each extending from the center portion, and means for attaching the first end portion being to the second end portion of a like device and the second end portion to the first end portion of a like device, the first and second end portions being sized such that, when attached, the combined thicknesses of the first end portion and the second end portion of the like device are substantially the same as the thickness of the center portion a

second elongated member having an edge, the second elongated member being attached to the first elongated member such that the first and second elongated members form a vertex at the attached edges; and

a third elongated member and means for positioning the third elongated member on the first elongated member such that the third elongated member extends upwardly from the plane of the first elongated member and wherein the third elongated member has an extension and means for securing the extension of a like third elongated member.

20. A lawn edging device, comprising:

a first elongated member having;

a center portion having an edge;

a first end portion and a second end portion, each extending from the center portion, the first end portion being attachable to the second end portion of a like device, the second end portion being attachable to the first end portion of a like device, the first and second end portions being sized such that, when attached, the combined thicknesses of the first end portion and the second end portion of the like device are substantially the same as the thickness of the center portion;

a second elongated member having an edge, the second elongated member being attached to the first elongated member such that the first and second elongated members form a vertex at the attached edges;
