Description
FIELD OF THE INVENTION
[0001] This invention deals primarily with a device that is hand
held and which is used to trim various objects, for example, the
toe nails of animals. The device is mechanized, driven by a motor,
such as the well-known Dremel.RTM. equipment, or an electric drill.
The component makeup of the instant device allows for the safe
trimming of various objects.
BACKGROUND OF THE INVENTION
[0002] Typically, those working in the industry of grooming pets
have used scissors and anvil type clippers to trim toe nails, but
quite often, the same individuals use hand held, abrasive devices
for the same job.
[0003] In recent times, some of those in the industry have turned
to hand held trimming devices that are mechanized rotary tools that
hold abrasive tools. There are many problems associated with such
hand held rotary devices in that they can overheat and cause
discomfort to the animal. In addition, such devices can entangle
long hair on animals, again at the discomfort of, if not, injury to
the animals being groomed. In addition, rotary tools known in the
prior art use beveled trimmer heads or purely circular trimming
heads and these configurations tend to displace the nails while
trimming.
[0004] One such device can be found in U.S. Pat. No. 4,654,334
issued to Su on Aug. 8, 1989 in which there is provided a power
supply, a driving means, a switch means, a trimming means and a
frame means for trimming nails.
[0005] Another device can be found in U.S. Pat. No. 7,428,881 that
issued to Drelinger on Sep. 30, 2008 in which there is provided a
device that is a rotary device that has a shroud and an opening in
the shroud to allow an animal's nail to be put through the opening
and shaped by the rotary grinder.
[0006] Drelinger discloses his invention again in U.S. Pat. No.
7,568,451.
THE INVENTION
[0007] Thus, what is disclosed and claimed herein is a trimmer
head, wherein the trimmer head has a forward end that has an
outside edge, a rearward end, and an outer surface. The head has a
long axis and is circular in configuration. The head contains on

the forward end 6 to the rearward end 8 of the trimmer 2. In this
embodiment, it should be noted, that the holes 32 are situated in
the trimming head 4 such that they may intercept the outside
surface 12 of the trimming head 4. The holes 32 promote cooling of
the trimmer head 4.
[0055] There are circumferential grooves 34 milled into the
trimming head 4 in a circumferential manner. These circumferential
grooves 34 are milled such that they intersect with the air holes
32. The holes 32 are vertical here. This configuration allows for
even more air to flow through the trimming head 4 and helps
alleviate heating of the trimming head 4 while in use.
[0056] It is usually sufficient to allow one such circumferential
groove 34, but this figure shows three such circumferential grooves
34 in the trimming head 4.
[0057] It should be further noted that this embodiment the trimmer
head 4 has a concave center portion 36.
[0058] FIG. 12 is a full side view of another of the device 2. This
embodiment of the device 2 has a head portion 4 that has a forward
end 6 and a rearward end 8. The rearward end 3 has a rearward
surface 18 that has a center point 16 that contains the shank 14.
The shank 14 has a near end 20 and a distal end 22. The near end 20
of the shank 14 has a thicker portion 24 than the thinner distal
end 22. The distal end 22 is configured to fit a motorized driving
mechanism. This embodiment also has an abrasive surface 28 on the
outer surface 12.
[0059] This embodiment has the holes 32 are angled from the forward
end 6 to the rearward end 8 instead of aligned along the long axis.
As in the other embodiments the outside surface 12 has an abrasive
surface 28.
[0060] There are circumferential grooves 34 milled into the
trimming head 4 in a circumferential manner. These circumferential
grooves 34 are milled such that they may intersect with the air
holes 32. The holes 32 are angled here. This configuration allows
for even more air to flow through the trimming head 4 and helps
alleviate heating of the trimming head 4 while in use.
[0061] It should be further noted that this embodiment the trimmer
head 4 has a concave center portion 36.
[0062] FIG. 13 is a full side view of another embodiment of the
device 2. This embodiment of the device 2 has a head portion 4 that
has a forward end 6 and a rearward end 8. The rearward end 8 has a
rearward surface 18 that has a center point 16 that contains the
shank 14, The shank 14 has a near end 20 and a distal end 22. The
near end 20 of the shank 14 has a thicker portion 24 than the
thinner distal end 22. The distal end 22 is configured to fit a
motorized driving mechanism. This embodiment contains
circumferential grooves 34.
[0063] It should be further noted that this embodiment the trimmer
head 4 has a concave center portion 36.
[0064] FIG. 14 is a full side view of the another embodiment of the
trimmer 2. This embodiment of the trimmer 2 has a head 4 portion
that has a forward end 6 and a rearward end 8. The rearward end 8
has a rearward surface 18 that has a center point 16 that contains
the shank 14. The shank 14 has a near end 20 and a distal end 22.
The near end 20 of the shank 14 has a thicker portion 24 than the
thinner distal end 22. The distal end 22 is configured to fit a
motorized driving mechanism. The holes 32 may pass through the
outside surface 12. The holes 32 again allow for trimmer head 4
cooling.
[0065] It should be further noted that this embodiment the trimmer
head 4 has a concave center portion 36.
[0066] The shank 14 is normally a standard shank that fits rotary
tools such as Dremel rotary tools, electric drills, and the like.
The shank 14 is thicker near the rearward end 8 of the trimming
head 4 to increase the strength of the shank 14.
[0067] The outside surface 12 of the trimming head 4 is an abrasive
surface 28.
[0068] The air holes 32 in the trimming head 4 are placed there to
convey air through the trimming head 6 to alleviate heating of the
trimming head 4 while in use.
[0069] Thus, the device of the instant, invention provides a means
of trimming toenails of animals that is safe for the operator, safe
for the animal being treated, is lightweight (hand held), provides
for maintaining toenails on the surface of the trimming head, and
is configured such that the trimming head does not overheat.
[0070] There is no size limitation to the device, as it can be made
to be hand held, or, for example, it can be large enough to use in
oil drilling operations or in heavy machinery repair or
manufacturing.
[0071] The number of openings or holes in each head can be as many
as is desired by the user. There is no limitation with regard to
the number of the holes in the head, or the size of the holes in
the head, or the exact configurations of the holes in the head.
Configurations can be, for example, as shown in the drawings
herein, round, but they could be triangular, square, rectangular,
octagonal, etc., depending on the desires of the user and
objectives of use.
[0072] In addition, the particular angle from the long axis as
recited herein is not critical and can be any angle that will allow
the air to pass through and cool the device and impair the end use
of the device.
