Description
BACKGROUND OF THE INVENTION
[0001] Pipes are often cut in different shapes and patterns for
various purposes such as constructing a fence, a gate or other
products made from a pipe or a tube. A pipe can be cut
perpendicular to its axis to construct a fence having a horizontal
or a flat top. A pipe can be cut at an angle to construct a fence,
wherein each pipe has an angular end. Also, a pipe can be cut in a
desired shape such as a saddle shape, wherein each pipe post in the
fence has a saddle-shaped end.
[0002] A pipe guide is generally used to mark a pipe prior to the
pipe being cut. A pipe guide is placed over the pipe to be marked
and a marking chalk or a pen is used to mark the pipe. The pipe
guide is thereafter removed from the pipe, and the pipe is cut
along the mark.
[0003] Existing pipe guides are typically cylindrical in shape
having two ends. One end of the pipe guide may be perpendicular or
may be at a particular angle with respect to the axis of the pipe
guide. A perpendicular end of the pipe guide allows a pipe to be
marked at a 90 degree angle. If the end of the pipe guide is at a
particular angle, the pipe can be marked at that angle. The other
end of the pipe guide can have a desired shape such as a saddle
shape to allow the pipe to be marked in a saddle shape. Thus,
existing pipe guides allow the pipes to be marked in two different
shapes or angles. For example, one end of a pipe guide may allow
the pipes to be marked in a saddle shaped pattern while the other
end may allow the pipes to be marked at a 90 degree angle. Thus, if
the pipes are required to be cut at different shapes and angles, a
single pipe guide is insufficient and consequently several pipe
guides each having different shapes and angles are needed to mark
the pipes.
[0004] Furthermore, the existing pipe guides do not provide a
mechanism to retain the pipe guide in place over the pipe while the
user can have free use of both hands. The existing pipe guides
require the user to use one hand to hold the pipe guide in place
over the pipe and use the other hand to mark the pipe.
[0005] Thus, there is a need for a pipe guide that allows a pipe to
be marked at different angles and patterns. There is also a need
for a pipe guide that provides a mechanism to retain the pipe guide
in place over the pipe, thereby allowing a user to use both hands
to mark the pipe.
BRIEF SUMMARY OF THE INVENTION
[0006] A pipe guide includes a pipe receiving body comprising two
sections. The two sections are joined by a hinge to allow the
pipe-receiving body to be opened and closed about a pipe. The
pipe-receiving body circumferentially surrounds the pipe in a
closed position.
[0007] The pipe receiving body includes one or more marking slots.
The marking slots allow the pipe inside the pipe-receiving body to
be marked in a predetermined pattern. The pipe guide includes a
hinge disposed longitudinally on the exterior of the pipe receiving
body. A device disposed inside the hinge retains the pipe-receiving
body in a closed position around the pipe.
[0008] The pipe receiving body is cylindrical having first and
second ends. The first end can be substantially perpendicular to
the axis of the pipe receiving body and configured to allow the
pipe to be marked at a 90 degree angle. The first end can be at any
other desired angle (e.g., 45 degrees, 221/2 degrees) or can have
any predetermined shape or pattern. The second end can have a
predetermined shape (e.g., saddle shape) or the second end can be
at a predetermined angle (e.g., 90 degrees, 45 degrees, 221/2
degrees).
[0009] The marking slots are formed at predetermined angles (e.g.,
45 degrees, 221/2 degrees). The marking slots are configured to
allow the pipe to be marked at the predetermined angles. The
marking slots can also have any predetermined shape or pattern
allowing the pipe to marked in a predetermined shape or
pattern.

DETAILED DESCRIPTION OF THE INVENTION
[0021] FIG. 1 illustrates a front view of one embodiment of the
pipe guide 100. The pipe guide 100 includes a pipe receiving body
104. The pipe receiving body 104 has a cylindrical shape and is
configured to receive a pipe (not shown in FIG. 1). The pipe
receiving body 104 includes two sections joined by a hinge (not
shown in FIG. 1) to allow the pipe receiving body 104 to be opened
and closed about the pipe. The pipe receiving body 104
circumferentially surrounds the pipe in closed position.
[0022] The pipe receiving body 104 has a first end 116 and a second
end 120. In one embodiment, the first end 116 is substantially
perpendicular to the longitudinal axis (indicated by the line
A1-A2) of the pipe receiving body 104. The first end 116 allows a
pipe to be marked at a 90 degree angle using, for example, a pen or
a marker. Once the pipe is marked, the pipe guide 100 can be
removed from the pipe and the pipe can be cut along the mark. The
first end 116 can be at any desired angle with respect to the
longitudinal axis A1-A2.
[0023] The pipe receiving body 104 has a second end 120. In one
embodiment, the second end 120 has a saddle shape as shown in FIG.
1. The saddle shaped second end allows the pipe to be marked in a
saddle pattern. The pipe is then cut along the mark to create a
saddle shape.
[0024] The first end 116 can be used to mark and cut pipes at a 90
degree angle and thus create a fence having a 90 degree cut at the
top. The second end 120 can be used to mark and cut pipes in a
saddle shape and thus create a fence having a saddle shape at the
top of the pipe posts. The first and second ends can have any
desired shapes or patterns or can have any desired angles.
[0025] A plurality of marking slots 108, 112 are created on the
pipe receiving body 104. The marking slots 108, 112 can be created
by stamping or punching out predetermined sections from the pipe
receiving body 104. The marking slots 108, 112 allow the pipe to be
marked at predetermined angles. In one embodiment, the marking
slots are created at a 45 degree angle and a 221/2 degree angle.
Thus the pipe can be marked and cut at a 45 degree angle or at a
221/2 degree angle. The marking slots 108 can have any other
desired angles or any desired shapes or patterns.
[0026] FIG. 2 shows a left side view of one embodiment of the pipe
guide 100. A hinge 204 is disposed longitudinally on the exterior
of the pipe receiving body 104. The hinge 204 allows the
pipe-receiving body 104 to be opened and closed about a pipe (not
shown in FIG. 2). The hinge 204 includes a hinge pin (not shown in
FIG. 2) to allow the two portions of the pipe receiving body 104 to
be joined and to be opened and closed about the hinge 204.
[0027] In one embodiment, a spring (not shown in FIG. 2) is
disposed inside the hinge 204. The spring allows the pipe-receiving
body 104 to remain in a closed position around the pipe.
[0028] FIG. 3 is a top view of the pipe guide 100. FIG. 3 shows the
pipe receiving body 104 and the hinge 204. In one embodiment, a
plurality of pads 304 are disposed on the inner wall of the pipe
receiving body 104. The pads 304 are made of rubber or other
selected material to allow the pipe guide 100 to firmly grip the
pipe in a closed position. In another embodiment, a layer of rubber
or other suitable material can be disposed on the inner wall to
allow the pipe guide 100 to firmly adhere to the pipe in a closed
position. The pads 304 or the layer of suitable material prevents
the pipe guide from sliding on the pipe when the pipe guide is not
held in place by a user.
[0029] The pipe guide 100 can having different diameters depending
on the size of the pipe to be marked. For example, the pipe guide
100 can have diameters of 17/8 inches, 23/8 inches, 27/8 inches,
31/2 inches, or 41/2 inches.
[0030] In one embodiment, the two sections of the pipe receiving
body 104 are made from a sheet of 16 gauge metal. The slots 108 and
the hinge 204 are created on the sheet of metal and the two
sections are joined by the hinge 204. The hinge 204 incorporates a
spring or a similar mechanism that will snap back shut the two
sections when opened around a pipe. The spring allows the pipe
guide 100 to remain attached to the pipe, allowing a user to have
both hands free while marking the pipe.
[0031] In one embodiment, the hinge 204 is a conventional hinge
having a rod inside the hinge. In one embodiment, the pipe guide
100 can be made of a plastic-type material. Other suitable
materials can be used to make the pipe guide 100.
[0032] In one embodiment, the slots are configured to allow a
marking chalk or a marking pencil to be used inside the opening to
reach and mark on the pipe. The second end 120, which has a saddle
shape, acts as a saddle guide allowing the pipe to be marked in a
saddle shape. The first end 116 allows the pipe to be marked at a
90 degree angle.
[0033] FIG. 4 is a flat plane view of one embodiment of the pipe
guide 100. FIG. 5 is a rear view of one embodiment of the pipe
guide 100. FIG. 6 is a left rear view of one embodiment of the pipe
guide. FIG. 7 is a right rear view of one embodiment of the pipe
guide. FIG. 8 is a left piece top view of one embodiment of the
pipe guide. FIG. 9 is a right piece top view of one embodiment of
the pipe guide.
[0034] It will be appreciated by those skilled in the art that
changes could be made to the embodiments described above without
departing from the broad inventive concept thereof. It is
understood, therefore, that this invention is not limited to the
particular embodiments disclosed, but it is intended to cover
modifications within the spirit and scope of the present invention
as defined by the appended claims.
