Snow shovel to over come the obstacle of height differences found
in expansion joints of concrete side walks
Abstract
The present invention is an improved snow shovel with a uniquely
designed bottom surface on the blade of the snow shovel. This
consists of a wedge like protrusion located at the working edge
portion of the blades' lower surface, extending back towards the
rear of the blade for a distance of about two inches, with the
acute angle, or the sharp portion of the wedge being the forward
working edge of the blade. By lowering the handle of said snow
shovel about ten inches, the rear portion of this wedge like
protrusion will act as a fulcrum to lift the working edge of the
blade up, so that the edge of the blade can slid up, over and past
any vertical obstruction such as caused by a crack or the expansion
joints in a concrete sidewalk that has one edge of the crack or
expansion joint higher than the other edge creating a vertical
barrier to the forward travel of the snow shovel as it is pushed
forward on the sidewalk. This protuberance will also act as a
reinforcement to the working edge of the blade, due to the extra
amount of material the blade is made of, at the point of the most
wear and abrasion, resulting in a much longer lasting snow shovel.
as stated above the protruion could be of other shapes in cross
section, such as half round or a wide "V". A set of small wheels
placed in the same position as the said protrusion will also serve
as a fulcrum whenever the handle of said snow shovel is pushed
downward for a small distance. Another improvement is the
polishing, and/or treating, and/or coating the blade with an anti
stick coating such as teflon.

Claims
What is claimed is:
1. An improved snow shovel that can pass over and past a vertical
barrier such as one created by a crack or an expansion joint in a
concrete sidewalk that has one edge of said crack or expansion
joint higher than the other edge creating a natural vertical
barrier to the forward progress of snow shovels as they are pushed
along a side walk while removing snow from said sidewalk.
2. An improved snow shovel as set forth in claim 1. wherein said
improved snow shovel can pass over and past said vertical
obstructions without having to be lifted manually off the surface
of the concrete sidewalk.
3. An improved snow shovel as set forth in claim 2. wherein said
improved snow shovel can pass over and past said vertical
obstruction by lowering the handle of said snow shovel about ten
inches and sliding it forward.
4. An improved snow shovel as set forth in claim 3. wherein said
improved snow shovel can pass over and past said vertical
obstruction due to the unique shape of the lower surface of the
blade of the said snow shovel.
5. An improved snow shovel as set forth in claim 4, wherein said
improved snow shovel can pass over and past said vertical
obstruction due to the unique wedge like protrusion on the bottom
surface of the blade of said improved snow shovel being used as a
fulcrum to lever the working edge of the blade of the snow shovel
up and above the vertical obstacle in front of it.
6. An improved snow shovel as set forth in claim 5. wherein said
improved snow shovel can pass over and past said vertical
obstruction due to the unique wedge like protrusion on the bottom
surface of the blade of said snow shovel, and at the same time the
wedge like protrusion which is located on the bottom surface of the
blade at the front working edge of said blade will reinforce this
edge with a large amount of the same material the blade is made of
thereby resulting in a much slower rate of wear as this surface is
scraped and worn off as the snow shovel is used, resulting in a
much longer lasting snow shovel,
7. An improved snow shovel as set forth in claim 6. wherein the
unique wedge like protrusion is not an original part of the blade
of the snow shovel, being made separate, and added to the blade at
a later time or date, by any of many ways of doing so, such as,
welding, riveting or bolting.
8. An improved snow shovel as set forth in claim 7. wherein the
protrusion instead of being a wedge like shape would be of another
shape, such as half round or a wide "V".
9. An improved snow shovel as set forth in claim 8. wherein the
said protrusin is replaced by a set of small wheels fixed to the
under side of said blade in the same area,
10. An improved snow shovel with a polished, and/or treated and/or
coated blade, with a non stick substence such as teflon
Description
[0001] This invention relates to shovels in general, and more
specifically to snow shovels in particular.
[0002] As part of home maintenance in winter, snow shovels are used
to remove accumulated snow from side walks, drive ways and other
areas.
[0003] There are many types of snow shovels made at the present
time, some have blades made of steel, some made of aluminum, and
some made of plastic, or a combination of all of the above, of
course they all have a handle attached, to control the above
mentioned blade. The handle can be made of wood or plastic. It can
be a straight, or curved, and have a spade type grip, or not.
[0004] One problem that is common to all the snow shovels that are
being manufactured at the present time is. As the front working
edge of the snow shovel blade is being pushed along the top surface
of the side walk, the working edge of the blade will encounter
breaks in the surface of the sidewalk. These breaks can be cracks
that have occurred or they can be man made expansion joints. If one
side or the other of the edges of these cracks or expansion joints
has dropped or lifted the working edge of the shovel can be
effected in one of two ways. If it is traveling from the high edge
to the low edge of the crack or expansion joint it will slide over
with no noticeable effect, but if it is passing from the low side
to the high side of the crack or expansion joint it will be stopped
short with a jolt. The snow shovel and all it's contents must be
manually lifted up above the higher surface of sidewalk before snow
shoveling can continue.
[0005] Another problem is snow sticking to the blade of the snow
shovel as it is being used.
[0006] This invention is a change to the design and shape of the
under side surface of the snow shovel blade, the changed area is
located near the front working edge of said snow shovel blade.
Starting at the front edge and continuing towards the back edge for
a distance of about two inches. and extending from the left side,
or left edge of the blade to the right side, or right edge of the
blade. In other words, changing the entire front area of the under
side of the snow shovel blade beginning at the front edge, and
continuing towards the back edge. for about two inches.
[0007] This invention consists of a wedge like protuberance of
material, usually of the same material the blade is made of, this
wedge like extension to the underside front edge of the blade of
the snow shovel is positioned so that the front edge of the wedge
like protrusion is at the front working edge of the snow shovel, as
we go back towards the back portion of the blade of the snow shovel
it becomes thicker and thicker for a distance of about two inches,
then bending at a more or less obtuse angle, turns upwards for a
distance of about half an inch to join the lower surface of said
blade. thus leaving a protuberance across the entire front edge, on
the under side of the snow shovel blade, this protuberance can now
be used as a fulcrum to lever the front edge of the snow shovel
blade above any obstacle encountered by gently pushing down on the
handle of the snow shovel. This protubrence that we have been
describing as a wedge like shape could be of other shapes, such as
a half round shape, or a wide "V" shape. or it could be a set of
small wheels.
[0008] An object of the present invention is to provide a new
improved snow shovel that can be used to remove snow from a side
walk with out being stopped by cracks and expansion joints that
have one edge of said cracks and expansion joints higher than the
other edge.
[0009] Another object of the present invention is to provide an
improved snow shovel that can slide past cracks and expansion
joints that have one edge of said joints higher than the other edge
without having to lift the shovel and its contents manually.
[0010] Another object of the present invention is to provide an
improved snow shovel that can slide past cracks and expansion
joints that have one edge of said joints higher than the other edge
do to the unique design of the bottom surface of said snow
shovel.
[0011] Another object of the present invention is to provide an
improved snow shovel that can slide past cracks and expansion
joints that have one edge of said joints higher than the other edge
by the very simple and effortless means of pushing down on the
handle of said snow shovel.
[0012] Another object of the present invention is to provide an
improved snow shovel that can slide past cracks and expansion
joints that have one edge of said joint higher than the other edge
by having a wedge like projection with a rounded corner, as part of
the lower surface, that can be used as a fulcrum to lever the
working edge of the blade of the snow shovel above the obstacle in
front of it.
[0013] Another object of the present invention is to provide an
improved snow shovel that can slide over and past cracks and
expansion joints that have one edge of said joint higher than the
other edge and will last longer as the blade will not wear off as
fast as an ordinary snow shovel due to the wedge like projection
that is part of the lower surface of the new improved snow
shovel
[0014] Another object of the present invention is to provide an
improved snow shovel that will prevent snow from sticking to it as
it is being used to shovel snow.
[0015] These and other objects and advantages of this invention
will become apparent upon reading the following description of
which the attached drawings form a part.
[0016] The drawings are two side view of a snow shovel.
[0017] FIG. 1, shows a snow shovel that has the new invention, a
wedge like protuberance on the bottom surface of said snow shovel.
It is resting on the surface of a concrete side walk with the front
working edge of the snow shovel blade stopped and blocked by the
higher surface of the next slab of concrete sidewalk that has risen
to a higher plane than the concrete slab it is resting on.
[0018] FIG. 2. Is another view of the same snow shovel resting upon
the same section of concrete sidewalk after the handle of said snow
shovel has been brought downward for about ten inches, showing how
the wedge like protuberance on the bottom surface of said snow
shovel has acted as a fulcrum lifting the working edge of the blade
up and above the surface of the raised surface of the next slab of
concrete sidewalk.
[0019] Referring to the drawing;
[0020] It is seen in FIG. 1. how the working edge 7, of the snow
shovel blade 3, that is resting upon the surface of a slab of
concrete sidewalk 1, is blocked and stopped from any further
forward motion by the next slab of concrete sidewalk 2, that has an
edge 8, that has risen to a higher position than the slab of
concrete sidewalk 1.
[0021] It is seen in FIG. 2. when the handle 4, of the snow shovel
9, is lowered downward, bringing the handle 4, about ten inches
closer to the slab of concrete sidewalk 1, the working edge 7, of
the blade 3, is forced upward by the wedge like protuberance 6,
acting as a fulcrum, freeing it from, and allowing it to pass over,
the higher edge 8, of the next slab of concrete sidewalk 2. and
allowing the snow shovel 9, to continue along the side walk with
out the snow shovel 9, and it's contents having to be manually
lifted free, the teflon coating or other non stick treatment is
located on the upper surface 5, of the blade 3 of the snow shovel
9.
[0022] This invention may be further developed within the scope of
the following claims, accordingly, it is desired that the foregoing
description be read merely as being illustrative of an operative
embodiment of this invention and not in a strictly limiting
sense.
