Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority to U.S. Provisional Patent
Application Ser. No. 61/201,971 filed Dec. 17, 2008, which is
incorporated by reference in its entirety as if fully set forth
herein.
TECHNICAL FIELD
[0002] The present application generally relates to devices and
methods for plowing material. More specifically, the present
application relates to plow devices which may be pushed by a
vehicle.
BACKGROUND
[0003] Motorized plows are well known in the art. Some motorized
plows are specialized vehicles designed specifically for plowing
while others are merely heavy duty vehicles with plow equipment
installed thereon.
[0004] Property owners occasionally have a need to plow material
along driveways and/or parking areas. The material may be snow,
dirt, gravel, mulch or other similar material. For example,
homeowners in the Midwest may need to plow snow from their
driveways several times during a winter. Because their plowing
needs may be sporadic, few property owners dedicate their resources
to obtaining a specialized plow vehicle or a heavy duty vehicle
which can accommodate attached plowing equipment.
[0005] Accordingly, there is a need for a plow that may be used
with a variety of conventional automobiles. Specifically, a need
exists for an easy to use snow plow specifically geared toward
homeowners with driveways and a conventional vehicle. There is
further a need for a plow which is not attached to a vehicle.

Each strut further comprising a tire wedge disposed at the second
end of the arm.
[0007] According to a second aspect of the present application, a
second example plow device is disclosed. The second example plow
device comprises: an adjustable blade and a plurality of struts
attached to the blade. The blade comprises a plurality of sections
which are movable with respect to one another, thereby enabling
adjustment of the blade width. Each strut comprises an arm
comprising a first end and a second end. Each arm being attached to
the blade at its first end. Each strut further comprising a tire
wedge disposed at the second end of the arm. Each tire wedge
comprising a flange.
[0008] According to a third aspect of the present application, a
method for plowing material is disclosed. The method comprises
configuring a plow device to engage a tire of a vehicle. The plow
device comprises a blade and a tire wedge. The method further
comprises engaging the tire wedge of the plow with the tire of the

DETAILED DESCRIPTION
[0015] FIGS. 1 and 2 illustrate a first example plow device 100.
FIG. 1 is a perspective front view of first example device 100.
FIG. 2 is a perspective rear view of first example device 100.
[0016] As shown, device 100 comprises a blade 110 for plowing
material. Example blade 110 comprises three sections 112, 114 and
116. Sections 112, 114 and 116 may be adjustable with respect to
each other such that the width of blade 110 may be collapsed or
extended. In alternate embodiments, blade 110 may comprise a single
section or selected sections of the blade 110 may be curved or
angled, for example to form a U or V shape. Example blade 110
further comprises an optional handle to accommodate configuring and
manually moving device 100.
[0017] Example plow device 100 further comprises two struts 120A
and 120B. Blade 110 and struts 120A and 120B may be constructed
from plastic or any appropriate metal or composite. For simplicity,
strut 120A will be described in detail herein, but it should be
appreciated that strut 120B comprises elements which correspond to
like elements of strut 120A.
[0018] Strut 120A comprises an arm 121A formed by telescoping
elements 122A and 124A which are moveable with respect to each
other to enable lengthening and/or shortening of arm 121A. When
plow device 100 is stored, telescoping elements 122A and 124A may
be fully collapsed to produce a small storage footprint. It should
be appreciated that in an alternate embodiment arm 121A may
comprise a single, non-adjustable element. It should be further
appreciated that while the illustrated adjustment mechanism
comprises telescoping elements 122A and 124A, any other length
adjustment mechanism known in the art are envisioned.
[0019] Strut 120A is attached to blade 110 at a first end of arm
121A, and a second end of arm 121A is attached to a tire wedge
130A. It should be appreciated that while arm 121A is illustrated
as directly attached to blade 110, in alternate embodiments, such
attachment may be indirect, using a bracket for example. Tire
wedges 130A and 130B are positioned to rest against front or rear
tires of a vehicle (not shown). Although tire wedges 130A and 130B
are illustrated as having a curvature that accommodates the
curvature of a tire, the tire wedges may be designed to have flat
surfaces in other embodiments. Further, although not illustrated,
the tire wedges may be designed to be adjustable, thereby
accommodating various tire sizes.
[0020] When a drive mechanism of the vehicle is engaged, the
vehicle tires engage and cooperate with tire wedges 130A and 130B.
The tires apply force to tire wedges 130A and 130B, and the force
is absorbed by struts 120A and 120B. Accordingly, the force is
transferred to blade 110 and plow device 100 is urged forward
thereby plowing material in front of plow device 100. Likewise,
when plowing material, tire wedges 130A and 130B are pushed into
and distribute the load to the tires.
[0021] Tire wedges 130A and 130B may be manufactured from steel,
plastic, aluminum or other similar material including composites,
and they may be adjustable to accommodate various tire sizes. Tire
wedges 130A and 130B may each comprise one or more flanges, such as
flange 135A. Although flange 135A is illustrated as disposed on an
inside edge of tire wedge 130A, in other embodiments, tire wedge
130A may comprise a flange on an outside edge of tire wedge 130A,
or on both the inside and outside edges of tire wedge 130A.
[0022] Flanges 135A and 135B cooperate with the side walls of
cooperating tires and prevent lateral or vertical movement or
slippage of plow device 100 as the vehicle moves and device 100
displaces the snow or other material.
[0023] Like tire wedge 130A, a wheel 140A is disposed at the second
end of arm 121A. Wheel 140A operates to support the second end of
arm 121A. Wheel 140A may further operate to properly position tire
wedge 130A with respect to a cooperating tire. Of course, the size
and location of wheel 121A may be varied in accordance with design
considerations in alternate embodiments of plow device 100.
Alternate embodiments may not employ the wheels, or the other
mechanisms may be substituted for the wheels, such as skis or
skids.
[0024] As illustrated in FIG. 2, blade 110 may form strut
receptacle 210A. The illustrated strut receptacle 210A forms a
hinge that permits strut 120A to be configured at various angles
with respect to blade 110. For example, strut 120A may be folded
substantially parallel with blade 110 for compact storage. Strut
120A may also be configured, for example, at a 45 degree angle to
blade 110 to plow material predominantly to one side of the
vehicle.
[0025] The illustrated hinge includes a locking mechanism 220A for
securing strut 120A into position relative to blade 110. While the
illustrated locking mechanism comprises a pin and various receiving
apertures, other mechanisms for securing strut 120A are
contemplated.
[0026] Referring now to FIGS. 3-5, there is illustrated a second
example plow device 300. Device 300 is designed to be a lightweight
embodiment with a small storage footprint. Device 300 comprises a
blade 310 with sections 312 and 314. Blade 310 further comprises a
support bar 318 which may provide structural support for blade 310.
Support bar 318 may further provide convenient attachment point for
other elements, such as strut receptacles 350A and 350B.
[0027] As illustrated, blade 310 may be V-shaped, and may comprise
a hinge (not shown) at the center of blade 310, between sections
312 and 314, to enable blade 310 to be folded for storage. In
alternative embodiments, blade 310 may be U-shaped or shaped in any
manner conducive to plowing.
[0028] Blade 310 further comprises a lower lip 319. Lip 319 is
designed to prevent blade 310 from catching on any cracks, defects
of inconsistencies in the surface from which material is to be
plowed. Lip 319 may be a different material from the rest of blade
310, such as rubber or plastic, to absorb the shock of passing over
any surface deformities. Further, the lower edge of lip 319 may be
set back from the upper edge, thereby angling the lip away from the
direction of travel when plowing to further improve
performance.
[0029] Device 300 further comprises two struts 320A and 320B which
are attached to blade 310 by strut receptacles 350A and 350B,
respectively. Struts 320A and 320B comprise arms 321A and 321B,
tire wedges 330A and 330B, flanges 335A and 335B and wheels 340A
and 340B, respectively.
[0030] Although strut receptacles 350A and 350B are illustrated as
fixed, they may be movably attached to blade 310 to enable struts
320A and 320B to slide toward the center of blade 310 for storage.
For example, instead of using bolts to fasten the strut receptacles
to the blade, removable pins may be used. Strut receptacles 350A
and 350B may be hinged to enable struts 320A and 320B to remain
substantially parallel in the event that blade 310 is folded for
storage. In an alternate embodiment, strut receptacles 350A and
350B may be hinged to enable struts 320A and 320B to fold around to
the front of blade 310 for compact storage.
[0031] As illustrated, device 300 may further comprise a horizontal
support member 360 to provide structural integrity to device 300.
Although not shown in the drawing figures, device 300 may also
include a tow-back mechanism to enable device 300 to be pulled back
by the vehicle at the conclusion of a plowing run. One example
tow-back mechanism may be a strap that is attached to device 300 at
one end and attached to the vehicle at the other end. Such a strap
may be attached to device 300 at a bracket or handle installed in
the center of support member 360, and it may be attached to the
vehicle at a hitch or by closing an end of the strap in the trunk
of the vehicle.
[0032] In an alternate embodiment, device 300 may comprise a
tow-back mechanism embodied as a tow-back arm attached to the
outside edge of a tire wedge. The arm may extend along the outside
tire wall to the side of the tire opposite the tire wedge. The arm
may comprise a finger or other mechanism that catches and
cooperates with the side of the tire opposite the tire wedge to
enable the device to be pulled back after a towing run.
[0033] In order to use the plow devices described herein, a user of
the plow extends to a desired width. The user may then configure
the struts attached to the blade by unfolding the struts at the
attached hinges, locking the struts into place, and extending or
collapsing the struts to extend the desired to the desired length.
The user then positions the plow device at one end of a vehicle so
that the tire wedges fit snugly against the tires and that the
flanges are snugly riding on the inside and/or outside tire walls.
Of course, these steps can be done in an interchangeable fashion
depending upon user preference.
[0034] The user may then engage the vehicle to move in a forward or
backward direction to engage the plow depending on whether the plow
is placed in front of the vehicle or behind the vehicle. The loads
and forces resulting from pushing material, such as snow, are
transferred from the blade of the device through the struts to the
tire wedges and ultimately to the tires. As the material is pushed
by the plow blade, the material is displaced to either side of the
vehicle.
[0035] The plow devices described herein are engaged by the tires
of a vehicle. One advantage of such plow devices is the ability of
a user to plow material using a conventional vehicle. A further
advantage of the described plow devices is that they may be used
without being physically attached or installed onto the
vehicle.
[0036] Notwithstanding that the numerical ranges and parameters
setting forth the broad scope of the invention are approximations,
the numerical values set forth in the specific examples are
reported as precisely as possible. Any numerical value, however,
inherently contains certain errors necessarily resulting from the
standard deviation found in their respective testing
measurements.
[0037] Furthermore, while the devices, systems, methods, and so on
have been illustrated by describing examples, and while the
examples have been described in considerable detail, it is not the
intention of the applicant to restrict, or in any way, limit the
scope of the appended claims to such detail. It is, of course, not
possible to describe every conceivable combination of components or
methodologies for purposes of describing the devices, systems,
methods, and so on provided herein. Additional advantages and
modifications will readily appear to those skilled in the art.
Therefore, the invention, in its broader aspects, is not limited to
the specific details and illustrative examples shown and described.
Accordingly, departures may be made from such details without
departing from the spirit or scope of the applicant's general
inventive concept. Thus, this application is intended to embrace
alterations, modifications, and variations that fall within the
scope of the appended claims. The preceding description is not
meant to limit the scope of the invention. Rather, the scope of the
invention is to be determined by the appended claims and their
equivalents.
[0038] Finally, to the extent that the term "includes" or
"including" is employed in the detailed description or the claims,
it is intended to be inclusive in a manner similar to the term
"comprising," as that term is interpreted when employed as a
transitional word in a claim. Furthermore, to the extent that the
term "or" is employed in the claims (e.g., A or B) it is intended
to mean "A or B or both." When the applicants intend to indicate
"only A or B, but not both," then the term "only A or B but not
both" will be employed. Similarly, when the applicants intend to
indicate "one and only one" of A, B, or C, the applicants will
employ the phrase "one and only one." Thus, use of the term "or"
herein is the inclusive, and not the exclusive use. See Bryan A.
Gamer, A Dictionary of Modern Legal Usage 624 (2d. Ed. 1995).
