ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to lawn and gardening devices and, more specifically, to a device that can be positioned in the ground, defining a border and preventing growth between the separated ground cover.
2. Description of the Prior Art
There are other lawn and gardening device designed for retaining and maintaining a specific lawn or garden appearance. Typical of these is the patent issued to Coates on Jul. 13, 1999 as U.S. Pat. No. 5,921,021, to Conway on Mar. 21, 2000, as U.S. Pat. No. 6,038,811, and U.S. Pat. No. 4,349,596 issued to Hendrix on Sep. 14, 1982.
Another patent was issued to Trageser on Feb. 8, 1983 as U.S. Pat. No. 4,372,079. Another patent was issued to Brylla et al on Mar. 7, 1989 as U.S. Pat. No. 4,809,459. Yet another U.S. Pat. No. 4,969,289 was issued to Trifiletti on Nov. 13, 1990 and still yet another was issued on Jun. 8, 1993 to Grimes as U.S. Pat. No. Des. 336,220.
Another patent was issued to Mantilla on Aug. 13, 1996 as U.S. Pat. No. 5,544,445. Yet another U.S. Pat. No. 5,857,288 was issued to Wiste on Jan. 12, 1999.
The lawn border and edging member of this invention has an elongated vertical wall member which has opposite vertical side surfaces, first and second opposite ends, and elongated top and bottom surfaces. A flat plate member is secured to the bottom surface of the wall member and has a width extending outwardly from each side of the wall member to maintain the wall member in a vertical position. The outer ends of the plate member extend longitudinally outwardly beyond each end of the wall member. The plate member has an offset portion on its bottom surface to receive an end extension portion of another juxta positioned member having an end extension portion of an horizontal slot to receive an end extension portion of another juxta positioned member having an end extension portion. The wall member has connecting means on it opposite ends for pivotal attachments to ends of similar wall members. The connecting means includes a tongue element on one of each ends and a size compatible horizontal notch on the other of the ends. A vertical hinge pin having a lower end, and a length greater than the height of the wall member extends through the overlapping tongue elements and horizontal notches. The hinge pins penetrate a ground surface upon which the member is mounted. The protruding ends of the plate members are in the shape of a semi-circle. Except for the hinge pins, the member described heretofore can be comprised of a single piece of molded material.
A lawn edging system and methods for edging a lawn are disclosed. The system includes a plurality of individual, integrally formed lawn edging units. Each unit includes a first portion and a substantially perpendicular second portion. The second portion includes a central section, having a length equal to the length of the first portion, and two end areas, which, when combined with the length of the central section, define a length greater than that of the first portion. The end areas are preferably rounded, but may be boxed, pointed, or scalloped. In use, an end area on one unit overlaps an end area of an adjacent unit while the first portions of the adjacent units abut. The second portion preferably includes an aperture for accepting a stake to anchor the unit into the ground. The aperture may be centrally located, or there may be a plurality of evenly spaced apertures. The design of the lawn edging device enables a plurality of lawn edging units to be nested compactly and packaged for sale or storage. In addition, the design of the lawn edging device enables the device to be either inserted into the ground to separate a grassy area from an adjacent ground area or placed against a vertical surface to separate the grassy area from the vertical surface. Thus two alternate methods of use are disclosed.
A material retainer strip for holding gravel in a roadway, lining a flower bed or garden plot and generally maintaining the integrity of two separate surface materials, comprising elongated, flexible resilient strips of material having a substantially C-shaped cross-section, the base lip thereof being wider than the top lip, the base lip being secured to a surface by stakes. Included are a plurality of splice joints of various shapes for connecting the ends of the strips either in alignment or to permit execution of an abrupt turn in direction.
The present invention entails a garden edging structure that surrounds a garden plot and separates the same from grass, vegetation, or soil that might lie outwardly of the garden plot. Specifically, the garden edging structure includes an inner continuous boundary or border that surrounds the garden plot and includes a lower ground engaging portion that anchors the same about the plot, and an above ground portion that tends to confine soil of the garden plot inwardly of the inner boundary. In addition, an outer boundary or border structure is provided and communicatively associated with the inner boundary structure. More particularly, the outer boundary structure is of a generally horizontal planar type material, such as vinyl, and extends about ground level continuously around the inner boundary. In the case where the garden plot is surrounded by grass, it is seen that the outer boundary would serve to support a portion of a lawn mower such that grass disposed about the outer edge thereof can be easily and cleanly cut.
An L-shaped lawn and garden edging has a leg that is inserted into the ground and a flange that rests on the ground to impede plant growth under the flange. When the edging is inserted into the ground adjacent a building or other above ground object, the grass adjacent the building need not be hand trimmed after the lawn is mowed with a mower. The present invention includes an edging having an upstanding retainer section joined to the junction of the leg and flange. The retainer section is useful for retaining selected above ground garden materials into desired areas. The flange may be slit to permit bending the edging into curved configurations. The ends of the edgings may be cut at an angle and placed into end facing contact to bound multi-sided areas. In a modified embodiment, the flange is pivotally connected to the leg by a hinge of material. The flange has a tongue that is selectively engageable with a groove in the leg to hold the flange rigidly to the leg and disengageable from the groove to permit folding the edging. In a further modified embodiment, the flange is a loose piece that has a pair of tongues that are slidable into a dovetail groove in the leg to permit selective use as a rigid edging and to permit rolling the flange and edging.
A garden edging device separates one area of a lawn from another. The edging device includes two upwardly facing generally flat elongated horizontal segments. Two elongated vertical segments, each integral with the first horizontal segment, depend downwardly from the first horizontal segment along the longitudinal edges of the horizontal segment. One of the elongated vertical segments is integral along it lower edge to one longitudinal edge of the second horizontal segment. An additional longitudinal vertical segment is integral with the second horizontal segment and depends downwardly from it. The upwardly facing segments are provided with recessed holes for receiving and countersinking the heads of stakes which secure the device to the ground. The device can be straight or curved and can be formed with folds permitting it to bent.
This device includes the ornamental design for the interlocking lawn and garden bed edging as illustrated in the drawings of the patent, including interlocking element.
A landscape edging device which is positioned about a border between a lawn or garden and a structure such as a sidewalk, driveway or building is characterized by a split horizontal member which is capable of downward displacement to allow mowers and other objects to traverse over the device, while providing sufficient height to be
