Grill Cleaning Tool
Abstract
A grill cleaning tool for scraping a grill having a plurality of
spaced apart parallel rods is disclosed. The tool includes a
scraper member attached to one end of an elongated handle at an
approximate ninety degree angle such that when the tool is engaged
to a grill rod, the plane of the scraper member is approximately
perpendicular to the engaged grill rod while the elongated handle
portion of the tool is disposed approximately parallel to the grill
surface. The scrapper member includes at least one C-shaped grill
receiving slot opening along one of its long edges, which is sized
to receive at least one grill rod of a predetermined size. The
grill cleaning tool is adapted to clean the entire surface of a
grill rod by combining an intuitive longitudinally reciprocating
motion along the grill surface and a simple pivoting of the tool
about the grill rod.

Description
BACKGROUND OF THE INVENTION--FIELD OF INVENTION
[0001] This invention relates to a scraping tool for cleaning a
grill surface with a plurality of spaced apart parallel grill rod
members like those found on a barbeque.
BACKGROUND OF THE INVENTION
[0002] Similar tools are disclosed in U.S. Pat. Nos. 2,747,911,
3,820,185 and 4,958,403. U.S. Pat. No. 2,747,911 to Kuever (1954)
discloses a scraping blade with a plurality of spaced apart
U-shaped notches to engage the grill surface; however, since this
tool engages multiple adjacent grill rods at the same time, it
requires the notches to be uniformly oriented in its direction of
opening and equally spaced apart in order to receive multiple rods
simultaneously, thus never allowing for the scraping edge to ever
reach the bottom side of the grill surface where the largest
deposits of burnt food and encrusted grease often builds up.
[0003] Other scraping blades have been proposed that engage each
grill rod individually in order to allow the scraping blade to move
freely about the entire circumference of grill rods including the
bottom surface. U.S. Pat. No. 3,820,185 to Phillips (1974)
discloses a scraping blade with a single U-shaped opening that
engages the topside of a grill rod. The blade must then be twisted
to either side in order to pivot the cleaning slot around the grill
so it may clean the under surface of the grill rod. However, this
tool still lacks the ability to clean both the top and bottom
surface of the grill rod with a single pass over the grill surface.
Another example, U.S. Pat. No. 4,958,403 to Martin (1990) discloses
a scraping blade with a T-shaped opening instead; however, the
effort required to manipulate the scraping blade about each grill
rod in an unnatural T-shaped motion pattern makes the grill
cleaning process too cumbersome in practice.
BACKGROUND OF THE INVENTION OBJECTS AND ADVANTAGES
[0004] Accordingly, several objects and advantages of the present
invention are: (a) to provide a scraping blade with a C-shaped
opening that can engage a grill rod from the side so that both the
top and bottom surfaces of the grill rod may be cleaned with a
single pass of the tool over the grill surface. (b) to provide a
scraping blade that with minimal rotation, orientates the C-shaped
opening to engage the rest of the grill rod surface to be cleaned
with a reciprocating longitudinal pass over the grill surface.
[0005] Further objects and advantages are to provide a scraping
blade with a recess on the same side of the C-shaped opening which
allows the blade to rotate further around the grill rod and thus
situating the opening to engage the remaining untreated grill rod
surface from the first pass of the tool in the center of the
C-shape opening to provide maximum surface contact for a complete
cleaning on the reciprocating return pass of the tool. Still
further objects and advantages will become apparent from a
consideration of the ensuing description and drawings.
SUMMARY
[0006] The present invention provides for a grill cleaning tool for
a grill having a plurality of parallel spaced apart grill rods. The
tool includes a flat scraper member having a C-shaped opening along
its long edge to engage a predetermined sized grill rod mounted to
an elongated handle at an approximate right angle, thereby
permitting the C-shaped opening to engage the top, side and bottom
surfaces of the grill rod while the scraper member is approximately
perpendicular to the grill rod and the elongated handle is disposed
approximately parallel to the grill surface. The tool is adapted to
clean the top and bottom surfaces of a grill rod with a single pass
over the grill rod.

DETAILED DESCRIPTIONS
[0011] FIG. 1 is a perspective drawing of the grill cleaning tool
10 for cleaning a barbeque grill surface or the like with a
multiple of spaced apart parallel grill rod members, three of which
11a, 11b and 11c are displayed. The tool consists of a scraper
member 20 preferably metallic, attached to an elongated handle 30,
which may be any length and may be adapted with a gripped handle
portion.
[0012] The scraper member 20 has a C-shaped opening or receiving
slot 21a and another elliptical shaped recess or clearance slot 22a
along its notched edge 24a. The size of the C-shaped opening 21 a
may vary to accommodate the different sizes of grill rods 11 the
scraper member 20 is intended to fit. The width of the scrapper
member 20 from its flat or non-perforated edge 25a to its notched
edge 24a and the shape and size of the clearance slot 22a can vary
depending on the spacing between grill members 11 of the type of
grill the scraper member 20 is designed to clean.
[0013] The scraper member 20 has an approximate ninety-degree angle
bend 23 in it so that when the receiving slot 21a is engaged with
the grill rod 11b, the elongated handle 30 of the grill cleaning
tool 10 is disposed approximately parallel to the grill rod
surface. The grill cleaning tool 10 is adapted to clean the entire
surface of the grill rod 11b with a simple longitudinally
reciprocating motion along the grill surface combined with a
minimal pivoting motion about the grill rod 11b, as shown by the
arrows in FIG. 1.
[0014] FIG. 2 is an end view of how the scraper member 20 can be
twisted about the grill rod 11b to allow for the C-shaped opening
21a to engage all edges of the grill rod 11b. When the scraper
member 20 is first engaged to the grill rod 11b, the C-shaped
opening 21a is in contact with the top, left and bottom surfaces of
the grill member 11b. This allows the scraper member 20 to
effectively clean both the top and bottom surfaces of the grill rod
11b with a single pass of the grill cleaning tool 10 along the
grill surface, which has generally been the limitation of previous
grill scrapers. The scraper member 20 can then be pivoted around
the grill rod 11 b in a simple clockwise or counterclockwise motion
to allow for the C-shaped opening 21a to clean the remaining
surface of the grill rod 11b on the return pass of the grill
cleaning tool 10.
[0015] The recess 22a allows for maximum clearance of the notched
edge 24a of the scrapper member 20 from the adjacent grill rod 11c
when a clockwise twisting motion is applied. The width of the
scraping member 20 is minimized to allow for free space between its
non-perforated edge 25a and the adjacent grill member 11a when the
scraper member 20 is engaged to the grill rod 11b in the starting
position and pivoted in a counterclockwise motion.
[0016] FIG. 3 is a fragmentary exploded perspective view of the
scraper member 20 and its receiving slot 31 on the elongated handle
portion 30 of the grill cleaning tool 10. The scraper member 20 is
provided with another set of receiving 21b and clearance 22b slots
oriented along the opposite end of the scraper member about the
angular bend 23 to accommodate a different size grill rod. The
openings 21b and 22b at the opposite end of the scraper member 20
is essentially identical to the openings 21a and 22b except that
the C-shaped opening 21a and 21b are sized differently to receive a
grill rod 11 of a different predetermined size.
[0017] The scraper member 20 also includes two mounting holes 26a
and 26b, one for each size setting of the C-shaped opening, 21a and
21b respectively. In practice, after the size of the C-shaped
opening, 21a or 21b has been matched to the grill rod 11 size in
question, the opposite portion of the scraper member not in use
will be inserted into the receiving slot 31 of the elongated handle
30 of the grill cleaning tool 10, leaving the selected half of the
scraper member 20 exposed for grill contact. Once the scraper
member 20 is inserted into the receiving slot 31, it is mounted in
place with a mounting screw 32 threaded through a mounting hole 33
on the elongated handle 30 and the selected mounting hole, 26a or
26b on the scraper member 20 and finally grounded to a receiving
nut or fastener 34.
[0018] Accordingly, the reader will see that the present invention
provides for a grill cleaning tool that can clean both the top and
bottom surfaces of a grill rod, where food deposits and grease
encrustations are the greatest, with a single pass of the tool
along the engaged grill rod. The problem of other grill cleaning
tools requiring the incorporation of awkward motion patterns in
order to manipulate the scraper member about the entire surface of
the grill rod is solved with an adaptation of a simple rotational
twist of the grill cleaning tool that effectively engages the
scraper member to the entire surface of the grill rod.
[0019] The invention incorporates the use of metal for the scraper
member, which allows the adaptation of a more streamlined shape and
a smaller size without any degradation in strength. The resulting
smaller scraping member allows for the maximum clearance between
grill rods which facilitates initial positioning of the cleaning
tool receiving slot around the grill member and provides the
crucial space required to maneuver the tool about the engaged grill
rod with an uncomplicated and effortless twisting and reciprocating
scraping motion.
[0020] Although the description above contains many specificities,
these should not be construed as limitations on the scope of the
invention, but rather as an exemplification of one preferred
embodiment thereof. Many other variations are possible. For
example, the scraper member can be of a different shape or length,
the recess on the scraper member can be of another shape or it can
be oriented on the flat edge of the scraper member or the scraper
member can have no recess at all, the scrapper member can be
extended to such a length as to not require a separate elongated
handle, etc.
[0021] Accordingly, the scope of the invention should be determined
not by the embodiment illustrated, but by the appended claims and
their legal equivalents.
