Abstract

An edge support for a margin of a lawn comprises an elongate generally L-shaped support member having a base part fixable to ground beneath the lawn, and an upstanding wall part to retain an edge of the lawn. The base part has elongate apertures to allow grass roots to grow therethrough. The base part may have several zones at which it may be cut or broken to permit bending of the wall part. The edge support may be provided with connectors to connect it to further edge supports via flanges on the wall part and the base part.

Claims

1. A curvable edge support means for a margin of a lawn, as defined herein, comprising an elongate generally L-shaped support member having an upstanding continuous wall part adapted to retain an edge of the lawn and provided along its upper margin with strengthening means;

a base part disposable beneath the lawn and fixable to ground therebeneath;

said base part comprising an elongate member provided along its margin remote from the wall part with strengthening means and an apertured lattice of strut members to connect the elongate member to the wall part, the lattice defining a plurality of elongate enclosed apertures, each elongate aperture extending substantially between the wall part and the elongate member and transversely to the wall part.

2. An edge support means as claimed in claim 1, wherein the elongate member extends substantially parallelly to the wall part.

3. An edge support means as claimed in claim 1, wherein the plurality of elongate apertures comprise at least one third of a total area of the base part.

4. An edge support means as claimed in claim 1, wherein the base part is provided with anchoring means.

5. An edge support means as claimed in claim 4, wherein the anchoring means comprises peg elements adapted to cooperate with apertures in the elongate member.

6. An edge support means as claimed in claim 1, wherein the elongate member is provided with a plurality of severable zones, any one of which may be severed as required to permit alteration, at any desired point, of the alignment of the wall part.

7. An edge support means as claimed in claim 6, wherein the wall part comprises zones of weakness adapted to facilitate its bending.

8. An edge support means as claimed in claim 1, wherein the strengthening means of the wall part comprises a flange member extending towards the base part.

9. An edge support means as claimed in claim 1, wherein the strengthening means of the base part comprises a flange member extending towards the wall part.

10. An edge support means as claimed in claim 1, provided with connection means to connect it to further edge support means.

11. An edge support means as claimed in claim 10, wherein the connection means is adapted to engage flange means of adjoining edge support means.

12. A method of protecting an edge of a lawn comprising the steps of providing an edge support means as claimed in claim 1, locating the base part thereof to a ground surface and so laying lawn material on top of the base part that an end of the lawn material abuts the wall part.

13. A method as claimed in claim 12, wherein the laying lawn material comprises laying turf.

14. A method as claimed in claim 12, wherein the laying lawn material comprises laying gravel.

15. A method as claimed in claim 12, comprising the step of removing existing lawn material from the lawn over at least an area corresponding to an extent of the base part.

16. A method as claimed in claim 12, comprising the step of peeling back existing lawn material over at least an area corresponding to an extent of the base part.

17. A method as claimed in claim 12, comprising the steps of providing a plurality of edge support means, and linking them in series before disposing them in position on the ground.

18. A method as claimed in claim 16, comprising the steps of providing a plurality of edge support means, and linking them in series after disposing them in position on the ground.

19. A method as claimed in claim 12, comprising the steps of digging a pond and laying a waterproof lining means over a base of the pond and a surface of the ground surrounding the pond, disposing the base part of the edge support means on top of said waterproof lining means, and laying thereon the lawn material.

21. An edge support means as claimed in claim 1, wherein the elongate member is coextensive with the wall part.

20. A curvable edge support means for a margin of a lawn, as defined herein, comprising an elongate generally L-shaped support member having an upstanding continuous wall part adapted to retain an edge of the lawn and provided along its upper margin with strengthening means;

a base part disposable beneath the lawn and fixable to ground therebeneath;

said base part comprising an elongate member provided along its margin remote from the wall part with strengthening means and an apertured lattice of strut members to connect the elongate member to the wall part, the lattice defining a plurality of elongate apertures, each extending substantially between the wall part and the elongate member and transversely to the wall part; and

the elongate member being provided with a plurality of severable zones, any one of which may be severed as required to permit alteration, at any desired point, of the alignment of the wall part.
