Description
FIELD OF THE INVENTION
[0001] The present invention relates generally to the field of
fences and, more particularly, to a system, method and apparatus
for assembling a picket fence.
PRIORITY CLAIM
[0002] This patent application is a non-provisional application of
U.S. provisional patent application 60/762,466 filed on Jan. 25,
2006 and entitled "System, Method and Apparatus for Assembling a
Picket Fence," which is hereby incorporated by reference in its
entirety.
BACKGROUND OF THE INVENTION
[0003] Current picket fence systems, especially metal picket
fences, are expensive (material and labor cost) and difficult to
install. For example, most systems require one or more pieces of
hardware to be added during assembly, such as screws, pins, spring
clips, caps, grommets, rods, plates, etc. Other systems have fewer
parts, but require special machining or tools (e.g., complex
shaped, custom made punches and tooling to produce components).
Moreover, many current systems can damage picket and/or rail during
assembly by sliding metal to metal, and/or leave the junction of
picket and rail open to the environment, and/or require an
additional hardware component to seal and provide cosmetic
cover.
[0004] As a result, there is a need for a system, method and
apparatus for assembling a picket fence that is rapid, easy and
less expensive than typical picket fences so that homeowners or
contractors can assemble a picket fence without tools or additional
hardware.
SUMMARY OF THE INVENTION
[0005] The present invention provides a system, method and
apparatus for assembling a picket fence that is rapid, easy and
less expensive than typical picket fences. Moreover, the present
invention allows homeowners or contractors to assemble a picket
fence without tools or additional hardware. The resulting fence
provides increased durability and security while maintaining the
clean aesthetic qualities of picket fence, which can be constructed
of metal (e.g., steel, iron, aluminum, alloys, etc.) or plastic
with a long life coating to prevent corrosion or UV degradation as
the case may be.
[0006] As will be seen from the following description and FIGURES,
the present invention provides at least the following advantages
over current fence systems: [0007] 1. The grip or single piece
fastener can be preinstalled in the rail. As a result, there is no
loose hardware to install during assembly. [0008] 2. Pre-installing
the grip or single piece fastener protects the finish on the
pickets and rail during assembly, and acts as a sealing grommet in
the finished configuration. This helps protect against
environmental forces and improves cosmetic appearance of assembled
fence. [0009] 3. The grip or single piece fastener can be made of
environmentally stable, UV resistant, high impact strength
injection molded material thereby keeping cost lower compared to
other fence system hardware. [0010] 4. The metal component cost is
also kept low by being using standard manufacturing equipment and
processes. For example, openings in the pickets and rails are made
using stock punches, thereby reducing cost and increasing
availability. [0011] 5. The system will allow for installation on
level grade or incline by allowing the grip or single piece
fastener to pivot around the openings in the picket. [0012] 6.
After assembly, the parts are permanently attached. One or more of
the components must be destroyed to disassemble the fence, which
makes for better security. [0013] 7. Shipping and storage cost of
system will be low since it can be shipped KD (knocked down).
[0014] 8. Rails can be attached to posts using "no tool/no
hardware" features or can be attached by conventional hardware
(screws). [0015] 9. The grip or single piece fastener will also
assist in orienting pickets all the same. Picket will not "snap"
into place if oriented 90 degrees out of place. This is important
for "spear-top" style pickets so they all face the same direction.
[0016] 10. Each picket can be secured in at least two rail
locations (upper and lower), which provides more strength than a
single attachment point.
[0017] More specifically, the present invention provides a picket
fence that includes two or more attachment surfaces, one or more
rails, one or more single piece fasteners and one or more pickets.
The one or more rails extend transversely to and are secured
between two of the attachment surfaces. Each rail has one or more
through apertures therein centered on a longitudinal axis of each
rail. A single piece fastener is substantially disposed within each
rail aperture and includes a housing having an aperture extending
from a first end to a second end of the housing. The one or more
pickets are vertically disposed between the rails and extend
through the vertically aligned single piece fastener apertures. The
attachment surfaces can be a post, a wall, a building or a
combination thereof. The single piece fastener locks into place
within the rail aperture and locks the picket into place without
any additional parts.
[0018] In addition, the present invention provides an apparatus to
fasten a picket to a rail of a picket fence that includes a
housing, a first fastener and a second fastener. The housing has an
aperture extending from a first end to a second end of the housing
and a flange extending transversely from the first end. The first
fastener is disposed between the first end and the second end to
engage the rail. The second fastener is disposed between the first
end and the second end to engage the picket. The cross section of
the aperture can be substantially circular, oval, square,
rectangular, triangular, hexagonal, polygonal or shaped to receive
a picket having a non-circular, non-oval, non-square,
non-rectangular, non-triangular, non-hexagonal, non-polygonal cross
section.
[0019] The present invention also provides a rail for a picket
fence that includes a rail member having one or more through
apertures therein centered on a longitudinal axis of the rail
member and a single piece fastener substantially disposed within
each rail aperture. The fastener includes a housing having an
aperture extending from a first end to a second end of the housing
to receive and secure a picket.
[0020] Moreover, the present invention provides a method of
fastening a picket to a rail of a picket fence by providing the
rail having one or more through apertures therein centered on a
longitudinal axis of the rail and a single piece fastener
substantially disposed within each rail aperture and inserting the
picket into the single piece fastener aperture. The fastener
includes a housing having an aperture extending from a first end to
a second end of the housing.
[0021] The present invention is described in detail below with
reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION
[0030] While the making and using of various embodiments of the
present invention are discussed in detail below, it should be
appreciated that the present invention provides many applicable
inventive concepts that can be embodied in a wide variety of
specific contexts. The specific embodiments discussed herein are
merely illustrative of specific ways to make and use the invention
and do not delimit the scope of the invention. The discussion
herein relates primarily to secure pickets within rails of a fence,
but it will be understood that the concepts of the present
invention are applicable to any situation where it is desirable to
lock a generally vertical member within an aperture of a generally
horizontal member with a single piece apparatus.
[0031] The present invention provides a system, method and
apparatus for assembling a picket fence that is rapid, easy and
less expensive than typical picket fences. Moreover, the present
invention allows homeowners or contractors to assemble a picket
fence without tools or additional hardware. The resulting fence
provides increased durability and security while maintaining the
clean aesthetic qualities of picket fence, which can be constructed
of metal (e.g., steel, iron, aluminum, alloys, etc.) or plastic
with a long life coating to prevent corrosion or UV degradation as
the case may be.
[0032] As previously mentioned, the present invention provides at
least the following advantages over current fence systems: (1) The
grip or single piece fastener can be preinstalled in the rail. As a
result, there is no loose hardware to install during assembly. (2)
Pre-installing the grip or single piece fastener protects the
finish on the pickets and rail during assembly, and acts as a
sealing grommet in the finished configuration. This helps protect
against environmental forces and improves cosmetic appearance of
assembled fence. (3) The grip or single piece fastener can be made
of environmentally stable, UV resistant, high impact strength
injection molded material thereby keeping cost lower compared to
other fence system hardware. (4) The metal component cost is also
kept low by being using standard manufacturing equipment and
processes. For example, openings in the pickets and rails are made
using stock punches, thereby reducing cost and increasing
availability. (5) The system will allow for installation on level
grade or incline by allowing the grip or single piece fastener to
pivot around the openings in the picket. (6) After assembly, the
parts are permanently attached. One or more of the components must
be destroyed to disassemble the fence, which makes for better
security. (7) Shipping and storage cost of system will be low since
it can be shipped KD (knocked down). (8) Rails can be attached to
posts using "no tool/no hardware" features or can be attached by
conventional hardware (screws). (9) The grip or single piece
fastener will also assist in orienting pickets all the same. Picket
will not "snap" into place if oriented 90 degrees out of place.
This is important for "spear-top" style pickets so they all face
the same direction. (10) Each picket can be secured in at least two
rail locations (upper and lower), which provides more strength than
a single attachment point.
[0033] Now referring to FIG. 1, a front elevation view of a section
of a picket fence 100 in accordance with one embodiment of the
present invention is shown. The picket fence 100 includes two or
more posts 102, two or more rails 104, one or more pickets 106 and
a single piece fastener (not shown) at each rail-picket interface
110. As illustrated in FIGS. 7 and 8, the present invention is
applicable to installations using any attachment surfaces (vertical
or non-vertical) and is not limited to two posts 102 (e.g., one
post and a wall, two walls, a post and a building, etc.) or two
rails (e.g., one rail, three rails, etc.). The posts 102 are
installed in the ground 108, surface structure (e.g., asphalt,
concrete, gravel, etc.) or on a structure (e.g., building, masonry
wall, etc.) using well know installation techniques. As shown, the
two or more rails 104 are spaced apart from one another and extend
transversely to and secured between two of the posts 102. Note that
the two or more rails 104 do not have to be perpendicular to the
posts 102 or the pickets 106 when the fence 100 is installed on
uneven ground 108. As illustrated in FIGS. 6 and 7, the present
invention is applicable to installations using one, two, three or
more rails 104. Each rail 104 is attached to the posts 102 using
well known techniques (e.g., "no tool/no hardware" features or
attached by conventional hardware (screws)). The posts 102, rails
104 and pickets 106 may be of any desired length, height and shape.
For example, the cross section of the picket 106 may be
substantially circular, oval, square, rectangular, triangular,
hexagonal, polygonal or other decorative shape. Moreover, posts
102, rails 104 and pickets 106 may be formed of suitable plastic or
metal material, and are typically hollow members.
[0034] Now also referring to FIG. 2, a perspective view of a
section of a picket-rail-post assembly in accordance with one
embodiment of the present invention is shown. Each rail 104 has one
or more through apertures (not shown) therein centered on a
longitudinal axis of each rail 104 wherein the respective rail
apertures are aligned. A single piece fastener 200 is substantially
disposed within each rail aperture. The single piece fastener 200
is molded, machined, formed or extruded from a suitable metal or
plastic material. The single piece fastener 200 includes a housing
having an aperture extending from a first end to a second end of
the housing. The one or more pickets 106 are vertically disposed
between the rails 104 and extend through the vertically aligned
single piece fastener 200 apertures.
[0035] Referring now to FIG. 3, three isometric views of an
apparatus or single piece fastener 200 in accordance with one
embodiment of the present invention are shown. The single piece
fastener 200 includes a housing 202, a first fastener 204 and a
second fastener 206. The housing 202 has an aperture 208 extending
from a first end 210 to a second end 212 of the housing 202 and a
flange 214 extending transversely from the first end 210. The first
fastener 204 is disposed between the first end 210 and the second
end 212 to engage the rail 104 (not shown). The second fastener 206
is disposed between the first end 210 and the second end 212 to
engage the picket 106 (not shown). The cross section of the
aperture 208 can be substantially circular, oval, square,
rectangular, triangular, hexagonal, polygonal or shaped to receive
a picket having a non-circular, non-oval, non-square,
non-rectangular, non-triangular, non-hexagonal, non-polygonal cross
section. The flange 214 can be of any desired shape and can extend
from two or more sides of the housing 202 (e.g., tabs). In
addition, the flange 214 can have a raised portion for additional
structural strength or to provide an ornamental appearance.
Although the flange 214 is shown to be at the first end 210, the
flange 214 can be disposed anywhere between the first end 210 and
the first fastener 204. The single piece fastener 200 is preferably
made of environmentally stable, UV resistant, high impact strength
injection molded material thereby keeping cost lower compared to
other fence system hardware. Metal component cost can also be kept
low by being using standard manufacturing equipment and processes.
For example, the openings or apertures in the pickets and rails are
made using stock punches, thereby reducing cost and increasing
availability. Other fence systems use complex shaped, custom made
punches and tooling to produce components.
[0036] As illustrated, the first fastener 204 may include a first
self-locking tab 204a disposed in a first quadrant 216 of the
housing 202 and a second self-locking tab 204b disposed in a third
quadrant 218 of the housing 202. Likewise, the second fastener 206
may include a third self-locking tab 206a disposed in a second
quadrant 220 of the housing 202 and a fourth self-locking tab 206b
disposed in a fourth quadrant 222 of the housing 202. FIG. 4
provides a top view, two side views and two cross sectional views
of a single piece fastener 200 in accordance with one embodiment of
the present invention. Note that the present invention is not
limited to the embodiment shown in FIGS. 3 and 4. For example, the
first fastener 206 may include one or more self-locking tabs and
the second fastener 208 may include one or more self-locking tabs.
Each self-locking tab can be integrated into the housing 202 and
may include an angled portion to engage the rail 104 (not shown) or
the picket 106 (not shown). Each self-locking tab may also include
a set of ridges to engage the rail 104 (not shown) or the picket
106 (not shown).
[0037] Now referring to FIGS. 5A and 5B, perspective cross
sectional views of a picket-rail assembly 110 in accordance with
one embodiment of the present invention are shown. Note that FIG.
5A corresponds to Section A-A in FIG. 4, and FIG. 5B corresponds to
Section B-B in FIG. 4. The rail 104 has one or more through
apertures 500 therein centered on a longitudinal axis of the rail
104. The single piece fastener 200 is substantially disposed within
each rail aperture 500. The single piece fastener 200 includes a
housing having an aperture 208 extending from a first end to a
second end of the housing to receive and secure the picket 106. The
single piece fastener 200 locks into place within the rail 104
aperture 500 via the first fastener 206 and locks the picket 106
into place via the second fastener 208 and picket aperture 504
without any additional parts. Picket aperture 504 can be created at
the factory or on site as desired by the customer or contractor. As
shown, the flange 212 of the single piece fastener 200 rests within
cavity 502, which is not required for the present invention, but
adds to the aesthetic appearance of the fence. The cavity 502 and
flange 212 interface can also help to seal the interface. Note that
the picket 106 may also include a swaged (swelled) area above the
upper single piece fastener 106 as a double redundant system to
resist extraordinary force being applied in a downward direction
(e.g., a person standing on top of one or more pickets).
[0038] As is apparent in these FIGURES, the single piece fastener
200 has numerous advantages, such as, low cost, easy installation
without special tools, can be pre-installed in the rail aperture
500, prevents movement of the picket 106 after installation,
substantially seals the rail aperture 500, the cross sectional
shape of the rail aperture 500 does not have to be identical to a
cross sectional shape of the single piece fastener aperture 208,
etc. Moreover, there is no loose hardware to install during
assembly. Other fence systems require one or more pieces of
hardware to be added during assembly, such as screws, pins, spring
clips, caps, grommets, rods, plates, etc. Pre-installing the single
piece fastener 200 in the rail 104 also protects the finish on the
pickets 106 and rail 104 during assembly, and acts as a sealing
grommet in the finished configuration. Shipping and storage cost of
the system can also be low since it can be shipped KD (knocked
down). The single piece fastener 200 also helps protect against
environmental forces and improves cosmetic appearance of assembled
fence. Other systems can damage picket and/or rail during assembly
by sliding metal to metal, and/or leave the junction of picket and
rail open to the environment, and/or require an additional hardware
component to seal and provide cosmetic cover.
[0039] The present invention also provides a method of fastening a
picket 106 to a rail 104 of a picket fence 100 by providing the
rail 104 having one or more through apertures 500 therein centered
on a longitudinal axis of the rail 104 and a single piece fastener
200 substantially disposed within each rail aperture 500. The
fastener 200 includes a housing having an aperture 208 extending
from a first end to a second end of the housing. The picket 106 is
inserted into the single piece fastener aperture 208. The process
may also include the step of inserting the single piece fastener
200 into each rail aperture 500. The present invention allows for
installation on level grade or incline by allowing the single piece
fastener 200 to pivot around the openings or apertures 504 in the
picket 106. After assembly, the parts are permanently attached. One
or more components must be destroyed to disassemble the picket 106
from the rail 104, which provides better security. The single piece
fastener 200 can also assist in orienting pickets all the same. In
such a case, the picket 106 will not "snap" into place if oriented
90 degrees out of place. This is important for "spear-top" style
pickets 106 so they all face the same direction.
[0040] Referring now to FIG. 6, a front elevation view of a section
of a picket fence 600 in accordance with another embodiment of the
present invention is shown. The picket fence 600 includes two or
more posts 102, a single rail 104, one or more pickets 106, a
single piece fastener (not shown) with an ornamental top at each
rail-picket interface 110. The posts 102 are installed in the
ground 108, surface structure (e.g., asphalt, concrete, gravel,
etc.) or on a structure (e.g., building, masonry wall, etc.) using
well know installation techniques. As shown, the rail 104 extends
transversely to and is secured between two of the posts 102. Note
that the rail 104 does not have to be perpendicular to the posts
102 or the pickets 106 when the fence 600 is installed on uneven
ground 108. The rail 104 is attached to the posts 102 using well
known techniques (e.g., "no tool/no hardware" features or attached
by conventional hardware (screws)). The posts 102, rails 104 and
pickets 106 may be of any desired length, height and shape. For
example, the cross section of the picket 106 may be substantially
circular, oval, square, rectangular, triangular, hexagonal,
polygonal or other decorative shape. Moreover, posts 102, rail 104
and pickets 106 may be formed of suitable plastic or metal
material, and are typically hollow members.
[0041] Now referring to FIG. 7, a front elevation view of a section
of a picket fence 700 in accordance with another embodiment of the
present invention is shown. The picket fence 700 includes at least
one posts 102, a structure 702 (e.g., a wall or building), three
rails 104, one or more pickets 106 and a single piece fastener (not
shown) at each rail-picket interface 110. The posts 102 are
installed in the ground 108, surface structure (e.g., asphalt,
concrete, gravel, etc.) and on the structure 702 (e.g., building,
masonry wall, etc.) using well know installation techniques. As
shown, the rails 104 extend transversely to and are secured between
the post 102 and structure 702. Note that the rails 104 do not have
to be perpendicular to the posts 102, structure 702 or the pickets
106 when the fence 700 is installed on uneven ground 108. The rails
104 are attached to the posts 102 and structure 702 using well
known techniques (e.g., "no tool/no hardware" features or attached
by conventional hardware (screws)). The posts 102, rails 104 and
pickets 106 may be of any desired length, height and shape. For
example, the cross section of the picket 106 may be substantially
circular, oval, square, rectangular, triangular, hexagonal,
polygonal or other decorative shape. Moreover, posts 102, rail 104
and pickets 106 may be formed of suitable plastic or metal
material, and are typically hollow members.
[0042] Referring now to FIG. 8, a front elevation view of a section
of a picket fence 800 in accordance with another embodiment of the
present invention is shown. The picket fence 800 includes two or
more attachment surfaces 802 (e.g., a column of a masonry wall),
two rails 104, one or more pickets 106 and a single piece fastener
(not shown) at each rail-picket interface 110. The attachment
surfaces 802 are installed in the ground 108 and have a connecting
structure 804 (e.g., lower masonry wall) between them such that the
rails 104 and pickets 106 are mounted above the connecting
structure 804 using well know installation techniques. As shown,
the rails 104 extend transversely to and are secured between the
attachment surfaces 802. Note that the rails 104 do not have to be
perpendicular to the attachment surfaces 802 or the pickets 106
when the fence 800 is installed on uneven ground 108. The rails 104
are attached to the posts 102 and attachment surfaces 802 using
well known techniques (e.g., "no tool/no hardware" features or
attached by conventional hardware (screws)). The attachment
surfaces 802, connecting structure 804, rails 104 and pickets 106
may be of any desired length, height and shape. For example, the
cross section of the picket 106 may be substantially circular,
oval, square, rectangular, triangular, hexagonal, polygonal or
other decorative shape. Moreover, rails 104 and pickets 106 may be
formed of suitable plastic or metal material, and are typically
hollow members.
[0043] Now referring to FIG. 9, a side view 900 of a picket 106
having "stops" 902 in accordance with another embodiment of the
present invention is shown. Stops 902 or bumps can be added to the
pickets 106 to add strength to prevent the picket 106 being pushed
down through the top rail 104 (e.g., if someone were to walk along
or climb over the tops of the pickets). Stops 902 or bumps also
prevent the picket 106 from falling through the rail 104a in the
event the fastener 200 or part of the fastener 200 breaks or fails.
In either case, the stops 902 or bumps will maintain the picket 106
at approximately the same height as the rest of the pickets and
thus maintain the aesthetic appearance of the fence. Typically, the
stops 902 or bumps are only added to the upper end of each picket
106, just above where the picket 106 meets the horizontal top rail
104. Note that picket apertures 504 are not shown in FIG. 9.
Although FIG. 9 show one stop 902 or bump on each side the picket
106, the number the stops 902 may be decreased or increase.
Moreover, the location of the stops 902 may be changed so the stops
902 are not centered or are placed on the corners of the picket
106.
[0044] Although preferred embodiments of the present invention have
been described in detail, it will be understood by those skilled in
the art that various modifications can be made therein without
departing from the spirit and scope of the invention as set forth
in the appended claims.
