Nut Gatherer and Method of Constructing Same
Abstract
A nut gatherer includes a hollow drum formed by a plurality of
wires. Each of the wires has a bowed middle segment and two end
portions. The end portions are preferably hooked. A pair of hubs
secures the hooked ends of the wires to form the drum there
between. A handle is rotatably mounted to the hubs and a handle
extension is removably coupled with the handle. In use, the handle
or handle extension is used to rotate the drum into contact with an
object, such as a nut, where the object then forces the wires to
separate and permit the object to move from outside the drum to
inside said drum. Once contact between the object and the wires is
terminated, the wires return to their original position thereby
trapping the object within the drum.

Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is based on and claims priority to U.S.
Provisional Application Ser. No. 61/482,012, filed on May 3, 2011,
which is incorporated herein by reference in its entirety.
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
[0002] Not applicable.
BACKGROUND OF THE INVENTION
[0003] Gardening and yard maintenance require a variety of tools.
Many of these tools are designed to efficiently remove debris or
yard waste. Rakes and brooms are typically used to maneuver yard
waste such as leaves, grass clippings and branches into piles for
removal. Some items, such as nuts and pine cones, are not easily
corralled using rakes or brooms because they pass through the tines
of the tool, are too bulky to be swept or roll away. Yet these
items are precisely the sort of yard debris that most gardeners
prefer to clear away as they do not decompose quickly, can cause
damage to lawn mowers and create a slipping hazard for people
desiring to use the space for recreation or leisure.
BRIEF SUMMARY OF THE INVENTION
[0004] The present invention is directed to a gardening tool for
gathering nuts and other debris, including but not limited to
pecans, acorns, walnuts, butternuts, hickory nuts, chestnuts,
filberts, gum balls, seeds, fruit, small balls, pine cones, seed
heads, shotgun shells and reusable paintballs. In a preferred
embodiment, the device includes an oblong wire capsule with a hub
positioned at either end. Each hub includes a hubcap coupled with a
hub disc. The hubcap has a flat bottom surface that mates with the
hub disc when the two components are coupled together. When
assembled, each end of the wires that make up the wire capsule is
trapped between the bottom surface of one of the hubcaps and one of
the hub discs. A handle is rotatably mounted to the hubs such that
the wire capsule can freely spin between the handle ends. A handle
extension is preferably attached to the handle, which allows a user
to roll the wire capsule along the ground or other surface to be
cleared from a standing position. As the wire capsule contacts
items, such as nuts and other debris, the wires flex to permit the
items to enter the interior of the capsule where they are trapped
when the wires return to their original position.
[0005] Additional aspects of the invention, together with the
advantages and novel features appurtenant thereto, will be set
forth in part in the description which follows, and in part will
become apparent to those skilled in the art upon examination of the
following, or may be learned from the practice of the invention.
The objects and advantages of the invention may be realized and
attained by means of the instrumentalities and combinations
particularly pointed out in the appended claims.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
[0011] With reference to FIG. 1, a nut gatherer in accordance with
a preferred embodiment of the present invention is shown and
generally designated by reference number 10. Nut gatherer 10
includes a convex wire drum 12, two hubs 14, a handle 16 and a
handle extension 18. The drum is formed of a plurality of flexible
wires 20. As described in further detail below, wires 20 are
secured at either end by hubs 14 to form drum 12. Handle 16 is
rotatably mounted to hubs 14 such that drum 12 spins freely in
either direction between the ends of handle 16. Handle 16 is also
configured to be removably attached to handle extension 18.
[0012] As shown in FIG. 2, each wire 20 has a bowed middle segment
22 and two hooked ends 24. Bowed middle segment 22 is shaped such
that it has a convex exterior surface and a concave interior
surface. Each hooked end 24 is preferably L-shaped. A first leg 24a
extends down from the end of bowed middle segment 22 and a second
leg 24b extends from the distal end of first leg 24a in an inward
direction under a portion of bowed middle segment 22. In a
preferred embodiment, approximately 72 wires of similar shape are
used to form drum 12. The wire is made of a metal material that is
sufficiently rigid to hold the basic shape described above but
sufficiently flexible and resilient that it will flex away from a
piece of debris during contact and return to its original position
when the contact with the debris is terminated.
[0013] With reference to FIG. 3, an exploded view of a hub is
shown. Each hub comprises a hubcap 26, a hub disc 28, a bolt 30 and
a nut 32. Hubcap 26 is hollow and approximately bell-shaped, having
a wide, round, open end and a narrow, round, open end. A flat plate
34 extends across the wide end of hubcap 26. Plate 34 defines a
center aperture having the same center axis as the narrow round
open end of hubcap 26. Hub disc 28 is round and has approximately
the same diameter as plate 34. Hub disc 28 also defines a center
aperture that shares the common center axis described above with
reference to plate 34 and hubcap 26.
[0014] As shown in FIG. 4, one surface of hub disc 28 defines a
plurality of grooves 36 and a plurality of cavities 38. Each of
grooves 36 is aligned with one of cavities 38. Cavities 38 are
arranged in a circle on hub disc 28. Grooves 36 radiate out from
cavities 38 to the perimeter of hub disc 28. Each groove and cavity
pair is shaped to retain a hooked end 24 of wire 20. The depth of
each groove 36 is slightly less than the diameter of first leg 24a,
such that when second leg 24b is fully inserted in cavity 38, a
portion of first leg 24a rests within groove 36 and a portion of
first leg 24a remains above the surface of hub disc 28. Hub disc 28
is preferably made of a material that is sufficiently rigid to hold
wires 20 in place but sufficiently flexible such that it will
permit slight lateral movement of the wire within the groove during
use.
[0015] Returning to FIG. 3, bolt 30 has a hollow threaded stem 40
and a head 42. Threaded stem 40 is shaped for insertion into the
center aperture defined by hub disc 28 and plate 34. Head 42 is
shaped to retain bolt 30 on one side of hub disc 28. The interior
surface of nut 32 is counter-threaded to threaded stem 40 such that
bolt 30 and nut 32 cooperatively work together to couple hub disc
28 with hubcap 26 when hub 14 is assembled. As described in further
detail below, threaded stem 40 is shaped to receive an end of
handle 16.
[0016] With reference to FIG. 5, hub 14 of nut gatherer 10 and a
portion of wires 20 are shown in an assembled state. Each end of
wire 20 is sandwiched between hub disc 28 and flat plate 34. To
make the nut gatherer of the present invention, multiple pieces of
wire 20 are cut to approximately the same length and bent such that
they each have a bowed middle segment 22 and two hooked end
portions 24. Each wire 20 is then mounted onto a hub disc 28 at
either end. Hub discs 28 are loaded with wires 20 by inserting the
end of second leg 24b into one of cavities 38. Once second leg 24b
is inserted, a portion of first leg 24a rests within corresponding
groove 36.
[0017] After hub disc 28 is fully loaded with wires 20, i.e., all
of cavities 38 have been filled with wires 20, flat plate 34 of
hubcap 26 is secured to the surface of hub disc 28 where wires 20
have been inserted using bolt 30 and nut 32. Threaded stem 40 of
bolt 30 is inserted through the center aperture of hub disc 28 and
plate 34 and nut 32 is threaded onto the stem such that nut 32 is
housed within hubcap 26. Coupling hub disc 28 and hubcap 26 in this
manner retains each of wires 20 in a cavity 38 and groove 36. Wires
20 are thus evenly spaced around the perimeter of hub 14 and their
bowed middle segments 22 collectively form drum 12. Friction
between first leg 24a of hooked end 24 and plate 34 of hubcap 26
prevents hub disc 28 from rotating relative to hubcap 26. Friction,
in conjunction with grooves 36, also prevents wires 20 from
collapsing onto one another during use. As shown in FIG. 1, handle
16 is coupled with hubs 14 by inserting one end of the handle into
the exposed hollow threaded stem 40 of bolt 30. Preferably, a
handle extension 18 is removably attached to handle 16.
[0018] In operation, handle extension 18 is used to push and pull
nut gatherer 10 along a surface to collect debris. As nut gatherer
10 is pushed or pulled along a surface with slight downward
pressure applied by the user, drum 12 rotates. When a pair of wires
20 is pressed onto a piece of debris, such as a nut, acorn, or
other object, the debris forces wires 20 to temporarily separate
and permit the debris to enter the interior of drum 12. Once the
debris has entered the interior of drum 12, wires 20 return to
their original position such that they will not permit the debris
to pass back out of the drum. Nut gatherer 10 can be operated in a
forward or backward motion, as drum 12 freely spins in either
direction between the ends of handle 16.
[0019] In alternative embodiments, more or less wires may be used
to form drum 12. The number of wires may depend on the size of the
target debris; if the target debris is small (such as an acorn),
then more wires should be used so that the wires are spaced closer
together, and if the target debris is larger (such as a walnut),
then less wires are needed as the spacing between them can be
greater. The bowed middle segment 22 of wires 20 may also be bent
to a greater or lesser degree. The more the wires are bent the more
disc-shaped drum 12 becomes, which means less surface area is in
contact with the ground at any one time. The less the wires are
bent, the more oblong-shaped drum 12 becomes, which means more
surface area is in contact with the ground at any one time.
Although metal wires are described with reference to the preferred
embodiment, plastic material that is sufficiently rigid yet
flexible and resilient may also be used.
[0020] In another alternative embodiment, the ends of the wires
have an inverted L-shaped end portion, where the second leg extends
from the distal end of the first leg and outward and away from the
bowed middle segment of the wire. In this embodiment, the end of
each wire is in a stair-step configuration where the first leg is
the riser between the second leg and the middle segment. To
accommodate wires having the stair-step configuration, the plate of
the hubcap defines the cavities and grooves described above,
instead of the hub disc, and the hub disc has a flat surface for
contacting the surface of the hubcap, i.e., the plate, where the
wires are inserted. In the assembled state, the second leg is
inserted into a cavity and the corresponding groove retains a
portion of the first leg in a similar fashion to that described
above with reference to the preferred embodiment. The wires are
loaded into each of the hubcaps until all the cavities and grooves
are full. The hub disc is then coupled to the loaded hubcap using
the nut and bolt such that the wires are trapped between the hubcap
and hub disc in their respective grooves and cavities.
[0021] In yet another embodiment, the ends of the wires include
only a single straight leg extending downward from the bowed middle
portion. In this embodiment, no cavities are provided in either the
hub disc or the plate of the hub cap. The straight leg is simply
trapped between the hub disc and hub cap when the two components
are coupled together. Preferably, grooves are provided in either
the hub disc or the bottom plate of the hub cap such that the
straight leg of each wire end partially rests within the groove and
the wires are prevented from collapsing onto one another during
use. Alternatively, no grooves (or cavities) are provided and the
straight wire end portions are held in place between the hubcap and
hub disc by frictional forces.
[0022] In a further alternative embodiment, no pre-made grooves are
provided. In this embodiment, the component defining the cavities
(either the hub disc as described with reference to the preferred
embodiment or the plate of the hub cap as described above with
reference to an alternative embodiment having wire ends in a
stair-step configuration) is made of a material that is
sufficiently pliable, such as rubber, to trap the wires in the
proper location when the hub is fully assembled. The wires are
pressed into the hub disc or plate to such an extent that they are
prevented from collapsing onto one another during use.
[0023] While specific embodiments have been shown and discussed,
various modifications may of course be made, and the invention is
not limited to the specific forms or arrangement of parts and steps
described herein, except insofar as such limitations are included
in the following claims. For example, the end portions of the wires
may be curved to form the hooked ends instead of bent at angles and
any method known in the art for coupling the hub disc to the hubcap
may be used instead of a nut and a bolt, such as a screw or bolt
and a threaded socket.
