Abstract
Abstract An edging strip useful in landscaping and other uses. The edging strip is an aluminum elongate extrusion having a generally uniform thickness. The strip, in vertical orientation thereof, has plural elongated grooves in one side thereof extending lengthwise of the strip and being vertically spaced from one another. The strip further has plural ribs projecting outwardly from an opposite side thereof and opposite the grooves at a vertical location on the aforesaid opposite side coinciding with the location of the aforesaid grooves. Each of the grooves has a pair of vertically spaced sidewall surfaces and a vertically upright bottom wall surface. The lowermost sidewall surface of each groove has a wall surface that is flat and inclined to the horizontal and defining an acute angle with the bottom wall surface. Each rib has a side facing surface that is parallel to the bottom wall surface and an upwardly facing surface that is upwardly inclined and defining an acute angle to the aforesaid side facing surface of each rib. A stake is utilized which overlaps at least a portion of each strip and has structure thereon for effecting a securement of each strip to the stake to prevent relative vertical movement therebetween.

Claim 1
Independent Claim
160 words
Edging useful in landscaping and other uses, comprising: an elongated extruded aluminum strip having a generally uniform thickness, said strip, in vertical orientation thereof, having plural elongated grooves in one side thereof, extending lengthwise of said strip and being vertically spaced from one another, said strip further having plural ribs projecting outwardly from an opposite side of said strip and opposite said grooves at a vertical location on said opposite side coinciding with the location of said grooves, each said groove having a pair of vertically spaced sidewall surfaces and a vertically upright bottom wall surface, the lowermost sidewall surface of each groove having a wall surface that is flat and inclined to the horizontal and defining an acute angle with said bottom wall surface, each said rib having a side facing surface that is parallel to said bottom wall surface and an upwardly facing surface that is upwardly inclined and defining an acute angle to said side facing surface.
Claim 2
Dependent Claim
160 words
Edging useful in landscaping and other uses, comprising: an elongated extruded aluminum strip having a generally uniform thickness, said strip, in vertical orientation thereof, having plural elongated grooves in one side thereof, extending lengthwise of said strip and being vertically spaced from one another, said strip further having plural ribs projecting outwardly from an opposite side of said strip and opposite said grooves at a vertical location on said opposite side coinciding with the location of said grooves, each said groove having a pair of vertically spaced sidewall surfaces and a vertically upright bottom wall surface, the lowermost sidewall surface of each groove having a wall surface that is flat and inclined to the horizontal and defining an acute angle with said bottom wall surface, each said rib having a side facing surface that is parallel to said bottom wall surface and an upwardly facing surface that is upwardly inclined and defining an acute angle to said side facing surface.
Claim 3
Dependent Claim
25 words
The edging strip according to claim 1, wherein said strip has a segment adjacent the lower edge thereof which is free of ribs and grooves.
Claim 4
Dependent Claim
123 words
The edging strip according to claim 1, including a further rib intermediate a top edge of said strip and the uppermost ones of said ribs and grooves, said further rib having a flat, downwardly facing surface opposing said upwardly facing surface on the uppermost ones of said ribs, and an elongated stake oriented so that the longitudinal axis thereof is perpendicular to the longitudinal axis of said strip, a portion of the upper end of said stake being bent back upon itself to define an inverted U, said strip being received between the legs of said inverted U, an inside surface of one of the legs of said U having a tab projecting outwardly therefrom and being adapted to engage said further rib.
Claim 5
Dependent Claim
20 words
The edging strip according to claim 3, wherein said stake has plural notches provided in the lateral side edges thereof.
Claim 6
Dependent Claim
30 words
The edging strip according to claim 3, wherein plural protuberances extend outwardly from a face of said stake on a side thereof remote from said portion of said upper end.
Claim 7
Dependent Claim
85 words
The edging strip according to claim 3, wherein said strip has at least one tab punched out from one side thereof and adjacent at least one end thereof, said tab being bent outwardly from a plane parallel to said side facing surface about an axis that extends vertically, said tab extending away from said axis toward the other end of said strip, said stake having stop means thereon adapted to engage said tab and prevent a lateral separation of said strip relative to said stake.
Claim 8
Dependent Claim
69 words
The edging strip according to claim 6, wherein said stake is adapted to operatively engage two of said strips oriented end-to-end, said stop means engaging a said tab on each strip to prevent a lateral separation of said strips from each other relative to said stake, said stop means further facilitating a pivotal movement of said strips relative to said stake about an axis generally perpendicular to said plane.
Claim 9
Dependent Claim
61 words
The edging strip according to claim 6, wherein said tab is located in and punched out from one of said grooves and projects outwardly from a said side facing surface of one of said ribs located in said inverted U of said stake, said stop means on said stake also being oriented within and between the legs of said inverted U.
Claim 10
Dependent Claim
84 words
The edging strip according to claim 6, wherein the mutually adjacent ends of a pair of strips are placed end-to-end with the grooves and ribs thereon aligned, said inverted U of said stake overlying said mutually adjacent ends; wherein a said tab is provided on each mutually adjacent end of said strip and on a part thereof located within said U; and wherein said stop means includes a pair of stops, one each adapted to operatively engage said further rib on each said strip.
Claim 11
Dependent Claim
174 words
The combination of an edging strip useful in landscaping and other uses and a stake, comprising: an elongated strip; a stake having a U-shaped top portion adapted to fit over the upper edge of the said strip, an elongated segment of said stake extending beyond the lower edge of said strip; and interlocking means on said stake and said edging strip for effecting an interlock therebetween, said interlocking means including rib means adjacent the top of said strip and having a flat, downwardly facing surface, an inside surface of one of the legs of said U-shaped top portion having a tab projecting outwardly therefrom and being adapted to engage said rib, said interlocking means including a tolerance spacing between said tab and said rib means on said strip and said downwardly facing surface to purposefully permit a pivotal movement between said stake and said strip about an axis that is perpendicular to a plane containing said strip and without causing said stake to be urged upwardly out of the ground as said pivoting occurs.
