Abstract

Lawn edging includes an elongated top portion which is removably cooperable with an elongated base portion. The top and base portions are interconnectable so as to form a single integrated unit. The base portion of the lawn edging includes a pair of upstanding walls which are parallel and spaced apart so as to receive a flange depending from the top portion. The base portion has a horizontally oriented base strip projecting perpendicularly outwardly from the lower end of the upstanding walls. A generally cylindrical ridge portion is formed along the longitudinal edge of the top portion so as to strengthen the top portion of the edging.

Claims

1. Lawn edging, comprising:

an elongated top portion removably cooperable with an elongated base portion;

said base portion having a pair of parallel upstanding walls with a slot formed between said walls; and

said top portion having a depending flange adapted to cooperate with said slot to form a single integrated unit, said depending flange having a length, depth and thickness substantially equal to said slot so as to slide vertically within the slot to completely fill said slot when said top portion and base portion are cooperably joined;

said top portion including a generally vertical strap extending the length of the top portion, said strap having a lower edge;

said depending flange having a thickness less than that of the strap and depending generally centrally from the lower edge thereof, so as to form shoulders on each side of the flange at the juncture to said lower edge;

said upstanding walls and slot therebetween having a total thickness equal to the thickness of said strap, so as to form flush vertical surfaces from said strap to said walls when said top and base portion are cooperably joined;

said base portion further comprising a generally horizontally oriented base strip from which said parallel walls project vertically upwardly, said strip located so as to project perpendicularly outwardly from said walls;

said top portion including an enlarged ridge portion wider than said depending flange and extending the length of said top portion to strengthen said top portion.

2. The lawn edging of claim 1, wherein said ridge portion is generally cylindrical.
