Description
RELATED APPLICATIONS
[0001] This application is related to U.S. Provisional application
No. 60/968555 filed Aug. 28, 2007, the contents of which are
incorporated herein.
BACKGROUND OF THE INVENTION
[0002] The present disclosure relates generally to paver edging
devices.
[0003] Paver edging devices are used to form edges of pathways or
other defined transit areas. The paver edging devices are generally
used to define the boundaries of such transit area to aid in
defining the limits of these areas when they are constructed. The
paver edging devices also may be used to define other areas, such
as the boundaries of gardens, parking areas, play areas, and other
such distinct property use areas.
[0004] Accordingly, a need therefore exists for improvement in
paver edging devices. The present invention addresses this and
other needs.
SUMMARY OF THE INVENTION
[0005] The present invention includes a paver edging device having
a linear metal strip having a bend along the length of the strip
and voids formed within the metal strip on a first side of the
bend, without passing to the edge thereof, and extending through
the apex of the bend.
[0006] The present invention also includes a method for using a
paver edging device comprising the steps of providing the
above-identified paver edging device, cutting the metallic area
from the void to the edge of the first side, bending the metal
strip on a second side adjacent to the location of the void, laying
the bent metal strip adjacent to a paver path and placing paver
components on top of the first side of the metal strip and adjacent
to the second side of the bent metal strip.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0012] Referring to FIGS. 1-3, the present invention includes a
paver edging device 10 formed from a linear metal strip 12, with
the metal strip 12 bent 14 along the length of the metal strip 12.
The metal strip 12 further includes one or more voids 20 formed
within the metal strip 12 on a first side 16 of the bend 14. The
second side 18 is preferably has a continuous solid surface area.
However the second side may have voids formed therein. The metal
strip 12 preferably has a composition of steel, aluminum or other
like metal.
[0013] The voids 20 are formed within the side of the metal strip
12 so that the void area does not pass through or invade edge 16E
of the first side 16 of the metal strip 12. As such, these void
areas constitute enclosed areas. Additionally, the voids 20 extend
into and through the apex 14A of the bend 14. Voids 20 formed
within the first side 16 may constitute any configuration or
arrangement, such as multiple voids linearly extending between the
apex 14A and the edge 16E of the first side 16, e.g., the area
between a first void 20 and the edge 16E of the first side 16 has a
second void 24 formed therein. Voids 20 may be formed to include
various distinct configurations. Voids 20 formed within the first
side 16 may constitute any appropriate amount effective for
retaining the integrity of the metal strip. Determination of the
amount of material absent on the first side 16 resulting from the
formation of the voids 20 therein is preferably made considering
desired weight, bending resistance, safety and other
characteristics affecting the use of the paver edging device 10. In
a particularly preferred embodiment, the voids 20 in the first side
16 of the paver edging device 10 constitute less than about fifty
percent, and more preferably less than about twenty percent of the
total area of the first side 16. FIG. 1 shows the paver edging
device 10 with voids 20 that are formed as an extended oval
configuration to project an end 20M of the void into and/or across
the apex 14A of the bend 14. With projection of the end 20M into
and/or across the apex 14A of the bend 14, the void 20 extends
through the apex of the bend 14, permitting the paver edging device
10 to be readily manipulated at that area. As seen in FIG. 3, this
embodiment shows the paver edging device 10 having triangular voids
20 that are formed to project an end 20M into the apex 14A of the
bend 14.
[0014] Although any appropriate angle of the bend in the metal
strip 12 may be used for a given use, the bend 14 in the paver
edging device 10 preferably forms an angle .alpha. of approximately
ninety degrees. Referring to FIG. 2A, FIG. 2A illustrates the metal
strip prior to bending into the paver edging device of FIG. 1,
which forms the shape shown in end view perspective of FIG. 2B,
once bent.
[0015] The paver edging device 10 may be formed of flat, smooth
and/or textured, surface areas, with flat surface areas preferred.
Ridges, ornamentation, and other design features may be included on
the surfaces or edges of the paver edging device 10. These design
features may include, for example, one or both edges of the metal
strip 12 forming an irregular edge.
[0016] Preferably, the paver edging device 10 includes a thickness
that is severable using a hand tool. As such, the thickness of the
paver edging device 10 preferably has a thickness of from about
0.15 inches or less, with more preferred thicknesses of from about
0.12 inches to about 0.02 inches, still more preferably from about
0.12 inches to about 0.07 inches. Representative gauges useful for
the paver edging device 10, include, for example, 20, 18, 16, 14
and 12 gauge material, with preferred gauges of from about 20 gauge
to about 16 gauge.
[0017] The paver edging device 10 may include additional features
useful in its placement or utility. These features include, for
example, holes 22 formed within the first side 16 for placement of
stakes therethrough, ridges within the first 16 or second side 18
surface areas, welded attachments, pictures or printed information,
etc. In one preferred embodiment, the paver edging device 10
includes a shearing indicator, or score line, 30 and 32 in the area
between the void 20 and the edge 16E of the first side 16. When
present, the shearing indicator 30 preferably has a reduced
thickness of the metal strip 12 to aid in hand tool cutting.
[0018] Representative dimensions of the surface area remaining
between the void 20 and the edge 16E on the first side 16 include,
for example, widths of from about one inch or less, such as from
about 0.15 inches to about 0.75 inches, or from about 0.25 inches
to about 0.3 inches, with selection of an appropriate space
determinable by one skilled in the art for a given size paver
edging device 10, gauge and/or purpose.
[0019] As seen in FIGS. 4A-4C, the selected 102 paver edging device
used in the placement or setting 100 of the paver edging device 10
is cut 104 at the area between the void 20 and the edge 16E of the
first side 16. The sheared 104 paver edging device is then bent 106
along the metal strip on the second side at the location of the
sheared void. Once the bent 106 paver edging device is laid 108 on
the ground along the paver path, paver components, such as shaped
stones, are placed 110 adjacent to the bent metal strip effective
to line the side of the bent metal strip. These steps preferably
include shearing multiple voids 20 and the edge 16E of the first
side 16, such as a second void 20. Multiple, e.g., second, third,
etc., shears may be made at any one void 20.
[0020] Once the first side 16 is cut the paver edging device 10 may
be conformed, e.g., curved, in either direction, such that the
bending or curving of the metal strip 12 on a second side 18 at the
location of the sheared void 20 causes the sides on either side of
the void 20 to overlap or diverge.
[0021] While certain embodiments of the disclosure have been
described herein, it is not intended that the disclosure be limited
thereto, as it is intended that the disclosure be as broad in scope
as the art will allow and that the specification be read likewise.
Therefore, the above description should not be construed as
limiting, but merely as exemplifications of particular embodiments.
Those skilled in the art will envision other modifications within
the scope and spirit of the claims appended hereto.
[0022] The foregoing description is provided to illustrate and
explain the present invention. However, the description hereinabove
should not be considered to limit the scope of the invention set
forth in the claims appended here to.
