FIG. 1 illustrates a diagonal perspective view of an extendable plow 100, in
accordance with one embodiment of the present invention.

CA 02845058 2014-03-07
The extendable plow 100 may include a center section 110 and a mounting
bracket 120. The center section 110 may have a front facing 110A and a back
facing
110B. The mounting bracket 120 may be coupled to the back facing 110B of the
center section 110. The mounting bracket 120 may include an attachment plate
122
and a first pair of cylinders 124. The attachment plate 122 may couple the
mounting
bracket 120 to a vehicle to push the extendable plow 100. The first pair of
cylinders
124 may be a hydraulic cylinder, a hydraulic cylinder or other suitable type
of
cylinder. The vehicle may be a commercial truck, a pick-up truck, a tractor, a
sport
utility van or SUV, an automobile or other suitable vehicle. The mounting
bracket 120
may include a pair of compression springs 126 to trip the extendable plow 100.
The
pair of compression springs 126 may be coupled to the back facing 110B of the
center section 110 of the extendable plow 100. The front facing 100A of the
extendable plow 100 may push any suitable material such as snow, ice, dirt or
gravel.
FIG. 2 illustrates an overhead perspective view of an extendable plow 200, in
accordance with one embodiment of the present invention.
The extendable plow 200 may include a center section 210, a plurality of side
extensions 220 and a transitional cutting edge 230. The center section 210 may
have a front facing 210A, a back facing 210B and a pair of sides 210C. The
side
extensions 220 may extend from each of the pair of sides 210C by a second pair
of
cylinders 224 to a plurality of predetermined lengths to accommodate different
sized
work environments and move more material. The second pair of cylinders 224 may
be a hydraulic cylinder, a hydraulic cylinder or other suitable type of
cylinder. The
transitional cutting edge 230 may be disposed on a bottom edge 210D of the
center
5
CA 02845058 2014-03-07
section 210. The transitional cutting edge 230 may allow moved material to
transition
smoothly from one plowing surface to another.
FIG. 3 illustrates a rear perspective view of an extendable plow 300 with a
transitional cutting edge 310, in accordance with one embodiment of the
present
invention. The extendable plow 300 may include a plurality of side extensions
320, a
transitional cutting edge 310 and a pair of vibrational mounting plates 330.
The side
extensions 320 illustrated in FIG. 3 are extended from a center section 322 of
the
extendable plow 300. The transitional cutting edge 310 may be extended from
the
center section 322 of the extendable plow 300 along a bottom edge 320A of each
of
the side extensions 320 with a pair of transitional cutting extensions 312.
The pair of
transitional cutting extensions 312 may also be disposed on the bottom edge
320A
of each of the side extensions 320. The pair of transitional cutting
extensions 312
may allow more moved material to transition smoothly from one plowing surface
to
another than the transitional cutting edge 310. The pair of vibrational
mounting
plates 330 may facilitate coupling the extendable plow 300 to a vehicle (not
shown)
that pushes the extendable plow 300.
FIG. 4 illustrates a front perspective view of an extendable plow 400, in
accordance with one embodiment of the present invention. FIG. 4 illustrates a
front
facing 400A of the extendable plow 400.
The extendable plow 400 may include an extension guide 410. The extension
guide 410 may be disposed on a top edge 410A of the front facing (FIG. 2,
210A) of
the center section (FIG. 2, 210) of the extendable plow 400.
FIG. 5 illustrates a front perspective view of an extendable plow 500, in
accordance with one embodiment of the present invention.

CA 02845058 2014-03-07
The extendable plow 500 may include an extension arm 510 disposed on
each side 500A of the extendable plow 500 and a gusset support system 520. The
extension arm 510 may each be adapted to be extended outward from the
extension guide (FIG. 4, 410) by the second pair of cylinders (FIG. 2, 224).
The
extension arm 510 may each be guided by the extension guide 410 as the
extension
arm 510 may each be guided outward. The extension arm 510 may each be coupled
to the side extensions (FIG. 2, 220) thereby resulting in the side extensions
(FIG. 2,
220) extending from the center section (FIG. 2, 210) of the extendable plow
500. The
extension arm 510 may each extend the pair of transitional cutting extensions
(FIG.
3, 332) disposed on the side extensions 220 while the side extensions 220 are
extended from the center section 210. The extendable plow 500 may include four
extension arms 510 but any suitable number of extension arms may be utilized
by
the extendable plow 500 to extend the side extensions (FIG. 2, 220). The
gusset
support system 520 may be an internal gusset support system 522. The gusset
support system 520 may be continuously welded and designed to provide strength
and support for the side extensions (FIG. 2, 220) when the side extensions
(FIG. 2,
220) are extended.
FIG. 6 illustrates a side perspective view of an extendable plow 600, in
accordance with one embodiment of the present invention. The extendable plow
600
may include a curvature 605 to assist directing pushed material pushed by the
extendable plow 600.
The extendable plow 600 may include a first plowtop extension 610 and a
second plowtop extension 620. The first plowtop extension 610 may be disposed
on
top of each of the pair of side extensions (FIG. 2, 220) extending from the
center
section (FIG. 2, 210). The second plowtop extension 620 may be disposed on top
of
7
CA 02845058 2014-03-07
the center section (FIG. 2, 210). The first plowtop extension 610 and the
second
plowtop extension 620 may assist to direct pushed material forward as the
pushed
material is driven up the pair of side extensions (FIG. 2, 220) and the center
section
(FIG. 2, 210). The extendable plow 500 may include four extension arms 510 but
any
suitable number of extension arms 510 may be utilized by the extendable plow
500
to extend the side extensions (FIG. 2, 220).
While the present invention has been related in terms of the foregoing
embodiments, those skilled in the art will recognize that the invention is not
limited to
the embodiments described. The present invention can be practiced with
modification and alteration within the spirit and scope of the appended
claims. Thus,
the description is to be regarded as illustrative instead of restrictive on
the present
invention.
