Abstract
The shoveling hand cart apparatus is a material handling apparatus
designed to provide an apparatus that will allow the user easy loading
of bulky and heavy items into a wheeled bin by having an open end
at or near load/ground height which aids in shoveling/scooping loads
in much the way a hand truck operates on boxed loads and allows the
user to easily transport contained and loose loads in a bin, and then
dump, shovel or slide out the contents of the bin. The shoveling hand
cart apparatus is comprised of a handle that has a significant vertical
portion prior to the portion that is positioned along the upper part
of the sides of the bin in order to permit the operator to work in
a comfortable position. The holding area or bin of the cart has a
rear arcuate wall and two sides with an open front section. The sides
have a vertical dimension that is greater at the area adjacent to
the rear arcuate wall and slopes as it goes forward to a smaller vertical
dimension. A set of large rear wheels is positioned at the convergence
of the sides and the arcuate rear arcuate wall. A set of smaller wheels
is positioned at the frontal area of the sides. The design allows
the heavy or bulky material to be loaded or unloaded through the open
front section of the apparatus.

Description
BACKGROUND OF THE INVENTION
[0001] This invention pertains to material handling landscaping
devices and, in particular, to a shoveling hand cart apparatus for
use by individuals to shovel and scoop and move large and bulky
items without the necessity of lifting the large and bulky items
over the elevated sides found in most garden carts or wheelbarrows.
[0002] There are a large number of devices used for carrying heavy
loads in landscaping and construction work. Obviously, the most
common device is the standard wheelbarrow. Another type of device
is the hand truck such as shown in U.S. Pat. No. 4,570,961. The
wheelbarrows can carry a heavy load and be pushed into rough areas,
but they have their limitations also. The individuals pushing them
have to maintain the balance of the wheelbarrow because of the large
single wheel at the forward structural area of the wheelbarrow.
Also, pushing a wheelbarrow puts an awful lot of pressure on the
back of the individual who picks up the handles with a load on the
wheelbarrow and then balancing them. Also it takes a lot of work
to load them as the material has to be picked up by hand or with
a shovel and placed into the wheelbarrow. They are also not suited
for very large or heavy items like boulders. Attempts have been
made to improve the wheelbarrow such as the U.S. Pat. No. 5,601,298
issued on Feb. 11, 1997 to Yoshihisa Watanabe for a Wheelbarrow.
[0003] Another type of device is the garden cart which usually
has two large wheels just forward of the midpoint of the structure.
It is much more stable but still requires a lot of effort to lift
items into the cart and lifting the handles with the cart loaded.
[0004] What is needed is a shoveling hand cart apparatus that permits
the user to load the device without having to lift the item and,
at the same time, is designed to be easy to balance and move from
one area to another. There is also prior art on shovels and shoveling
devices with wheels, such as the U.S. Pat. No. 4,161,073 issued
to Jul. 17, 1979 to William Oakes for a "Snow Scoop" and
the U.S. Pat. No. 4,214,385 issued to Boleslaw Baranowski et al
for a "Apparatus For Taking Up and Removing matter From a Surface".
There are some with large almost bin like shovels. However, these
devices are primarily wheeled shovels to aid in the shoveling of
loose items rather than the lifting and transport of other types
of heavy bulky loads. These devices do not have great maneuverability
and operability working under heavy loads, nor do they to push and
hold the bin at various angles of attack in order to scoop loads
at a walking pace.
[0005] It is the object of this invention to teach a shoveling
hand cart or truck apparatus which avoids the disadvantages and
limitations, recited above in previous wheelbarrow and garden cart
shoveling apparatus. Another object of this invention is to provide
an apparatus that is inexpensive to manufacture, can be massed produced
and can be easily used and set up by the user and, at the same time,
be effective with heavy loads and also with a variety of large,
bulky loads from shoveling snow to moving bulky boulders.
SUMMARY OF THE INVENTION
[0006] Particularly, it is the object of this invention to teach
a shoveling hand cart apparatus, for use by individuals in order
to easily handle bulky or heavy loads with an apparatus that can
be quickly loaded and unloaded, comprising a unibody chamber for
receiving heavy or bulky loads; said unibody chamber having a base,
side walls and an arcuate rear section for enclosing said heavy
or bulky loads; said unibody chamber having a rear wheel assembly
positioned above the bottom edge of said base of said chamber and
adjacent to said side walls and said arcuate rear section; said
unibody chamber further having a front wheel assembly positioned
above the bottom edge of said base and adjacent to the forward portion
of said side walls; and handle means attached to said side walls
for operating and controlling said shoveling hand cart apparatus.
[0007] It is also the object of this invention to teach a shoveling
hand cart apparatus, for use by individuals in order to easily handle
bulky or heavy loads with an apparatus that can be quickly loaded
and unloaded, comprising in combination a unibody chamber for receiving
heavy or bulky loads having a base, side walls and an arcuate rear
section with an open front section, said chamber having a rear wheel
assembly and a front wheel assembly and handle means attached to
said side walls for operating and controlling said shoveling hand
cart apparatus.
BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Further objects and features of this invention will become
more apparent by reference to the following description taken in
conjunction with the following figures, in which:
[0009] FIG. 1 is a top plan view of the novel shoveling hand cart
apparatus;
[0010] FIG. 2 is a side elevation view thereof;
[0011] FIG. 3 is a bottom plan view thereof;
[0012] FIG. 4 is a frontal elevational view thereof; and
[0013] FIG. 5 is a rear elevational view thereof.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0014] As shown in the figures, the novel shoveling hand cart apparatus
10 comprises a device having a base 11 with a pair of sidewalls
12 and 12a with a curved rear wall 13 forming a unibody bin 14 constructed
of stamped metal, molded wood fiber, plastic or fiberglass. The
combination of the base 11, sidewalls 12 and 12a and the curved
rear wall 13 form the unibody holding bin 14 that has an open front
side to facilitate loading and unloading. The edge 15 of the base
11 at the open side is reinforced 16 to ensure the durability of
the shoveling hand cart apparatus. The curved rear wall 13 has a
greater vertical elevation than the sidewalls 12 and 12a. The vertical
elevation of the sidewalls 12 and 12a is also angled downward as
the sidewall 12 and 12a extends toward the front open portion of
the shoveling hand cart apparatus 10.
[0015] The handle 17 of the shoveling hand cart apparatus is uniquely
designed to provide the maximum leverage for the individual using
the cart. It has an extended descending vertical section 18 which
extends downwardly almost to the level even with the base 11 of
the apparatus. The handle 17 then curves 19 and 19a inward toward
the apparatus and then extends 20 and 20a to the elevated area where
the sidewalls 12 and 12a meet with the curved rear wall 13 and then
is attached 21 and 21a to the sidewalls 12 and 12a along the top
edge 22 and 22a of the sidewalls 12 and 12a. The unique design of
the handle allows the user to push and gently lift the apparatus
to move it and vary the angle of attack of the front portion of
the unibody bin to scoop and shovel loads at various heights and
speeds.
[0016] The other feature which provides a great leverage and support
are the two sets of wheels on the apparatus. The large rear wheel
23 and 23a are located just forward of the point at which the rear
wall 13 meets the sidewalls 12 and 12a. An axle 24 is attached on
the side or to the bottom side of the base 11 and connects the two
rear wheels 23 and 23a to the apparatus 10. The two smaller front
wheels 25 and 25a are located just in back of the forward edge 15
of the shoveling hand cart apparatus 10 and are attached by means
of an axle 26 attached on the side of the bin or the bottom of the
base 11. This positioning provides a great deal of stability for
the apparatus. It also acts as a load bearing structure as are the
rear wheels. The front glide wheels serve to keep the front edge
from tripping on the surface and they aid in keeping the bin from
diving too deeply into a load.
[0017] In operation, the user would move the shoveling hand cart
apparatus the load to be moved. The cart can then be levered under
a load similar to a hand cart, shoveled into a pile of material
or the material can be loaded into the holding bin area of the shoveling
hand cart apparatus. When the load is in position, the cart can
then be wheeled to whatever location the individual desires and
then unloaded by shoveling out the holding bin area or by simply
dumping the load by lifting the handle which tilts the bin.
[0018] While I have described my invention in connection with specific
embodiments thereof, it is clearly to be understood that this is
done only by way of example and not as a limitation to the scope
of my invention as set forth in the objects thereof and in the appended
claims.
