DOOR FRAME POST, AND DOOR FRAME ASSEMBLY COMPRISING
SAME AND KIT FOR ASSEMBLY OF SAME
Field of the Invention
[0001] The present invention relates generally to door frames and in
particular, to a door frame post, and a door frame assembly comprising the
same and a
kit for assembly of the same.
Background of the Invention
[0002] Door frames of dwellings and other buildings are often constructed
by
installing wooden side plates and a wooden top plate around a doorway opening.
Wooden casings are typically attached to the edges of the side and top plates.
Hinges
and lock set recesses are then added to opposite side plates.
[0003] As will be appreciated, this approach requires considerable
handiwork
and the exercise of some degree of skill. It also requires significant on site
labour,
and is typically time-consuming. Additionally, this approach also does not
provide
for weather proofing, and weather proofing typically needs to be improvised by
attaching weather stripping around the edges of the doorway opening.
[0004] To facilitate door frame construction, it may be desirable and
more
cost-effective to utilize a pre-fabricated door jamb comprising inexpensive
structural
materials such as plastic. Door jambs comprising extruded plastic have been
previously described. For example, U.S. Patent No. 6,557,309 to Johnson
discloses a
door jamb assembly having an interchangeable multi-component design allowing
for
the framing of doorways with different configurations by first selecting a
main frame
and a decorative trim that conforms with the doorway, and then securing a
first end of
the main frame, being attached to the decorative trim, onto a wall with the
use of an
attachment flange and securing a second end of the main frame to an interior
jamb
with the use of a fastener.
[0005] U.S. Patent No. 7,472,519 to Careri discloses a plastic door jamb
member for forming a portion of a doorjamb, the plastic member having a recess
for
receiving a wooden door jamb portion, and an interlocking attachment recess
for
interconnection with a metal reinforcement plate. The plastic door jamb member
may
be interengaged with the wooden door jamb portion, and further interengaged
with the
CA 02832029 2013-10-31
- 2 -
metal reinforcement plate, and installed in position as a combination door
jamb
assembly.
100061 Door frame posts for door frames have also been described. For
example, PCT Application No. WO 2009093205 to Sciara discloses a standard post
for door and window frames comprising an elongate body with a longitudinal
axis, an
inner edge and an outer edge substantially parallel to the longitudinal axis
and end
edges substantially transverse to the longitudinal axis. The end edges are
both inclined
to the longitudinal axis, with substantially identical angles of inclination,
one of the
inclined edges being designed to be removed upon installation by a cut
substantially
at right angles to the longitudinal axis to define the lower end of the post,
whereas the
other one of the inclined edges is designed for connection with the lintel.
100071 Improvements are generally desired. It is therefore an object at
least to
provide a novel door frame post, and a door frame assembly comprising the same
and
a kit for assembly of the same.
Summary of the Invention
100011 In one aspect, there is provided a door frame post comprising: an
extruded, longitudinal post member comprising at least one longitudinal
internal
cavity and a longitudinal external channel; a longitudinal frame member
matingly
engaging the external channel of the post member; and one or more longitudinal
filler
strips inserted into the at least one internal cavity, each filler strip
comprising at least
one longitudinal cavity for receiving one or more fasteners.
100021 Each filler strip may be extruded.
[0003] Each filler strip may be formed separately from the post member.
[0004] The one or more fasteners may be screws.
[0005] The frame member may comprise a shaped longitudinal portion for
matingly engaging the external channel of the post member. The frame member
may
further comprise at least one longitudinal groove adjacent the shaped
longitudinal
portion, and wherein the post member further comprises at least one
longitudinal clip
member disposed adjacent the external channel, each clip member engaging a

Detailed Description of the Embodiments
1000271 Turning now to Figure 1, a door jamb assembly is shown and is
generally indicated by reference numeral 20. Door jamb assembly 20 is
configured to
be installed in a doorway opening (not shown) of a wall for accommodating a
door
(not shown). The door jamb assembly 20 comprises three (3) door jamb portions
22
that are connected by two (2) corner keys 24.
[000281 The door jamb portion 22 may be better seen in Figures 2 to 5.
Each
door jamb portion 22 comprises an extruded, longitudinal door jamb member 30
and a
CA 02832029 2013-10-31
- 5 -
longitudinal frame member 32. In this embodiment, the door jamb member 30 is
fabricated of polyvinyl chloride (PVC) -cap stock", and is formed by co-
extrusion of
recycled (or "regrind") PVC and new PVC so as to provide a body of recycled
PVC
that is coated with layer of new PVC, as is known in the art. The door jamb
member
30 comprises a plurality of longitudinal internal cavities, which extend the
length of
the door jamb member 30 and which are separated by longitudinal internal webs.
In
the embodiment shown, the door jamb member 30 comprises a first internal
cavity 34,
a second internal cavity 36 and a third internal cavity 38.
[00029] The door jamb member 30 also comprises a plurality of longitudinal
channels that extend the length of the door jamb member 30. In the embodiment
shown, the door jamb member 30 comprises a rounded channel 40 that extends the
length of the door jamb member 30, and which is configured to engage the frame
member 32 as described below. The door jamb member 30 further comprises a
biased, longitudinal clip member 42 disposed along a first side of the rounded
channel
40, and a longitudinal rib 44 disposed along a second side of the rounded
channel 40.
Additionally, the door jamb member 30 comprises a channel 46 that is sized and
shaped for accommodating a longitudinal reinforcement member (not shown)
having
a corresponding profile. The door jamb member 30 further comprises a channel
47
that is sized and configured to accommodate weather stripping, and a biased,
longitudinal clip member 48 spaced from a longitudinal external corner 49
which
together define an external, longitudinal channel 51 therebetween. The channel
51 is
configured to accommodate trim surrounding the exterior of the doorway
opening,
such as for example a brick mold portion.
[00030] In this embodiment, each frame member 32 is formed by machining a
longitudinal wooden board. In the embodiment shown, the frame member 32
comprises a rounded longitudinal edge 50, a longitudinal groove 52 disposed
along a
first side of the rounded longitudinal edge 50, and a longitudinal notch 62
disposed
along a second side of the rounded longitudinal edge 50.
1000311 The rounded longitudinal edge 50 of the frame member 32 and the
rounded channel 40 of the door jamb member 30 are configured to matingly
engage
so as to form a "bullnose" joint therebetween. When engaged in this manner,
the
longitudinal rib 44 matingly engages the longitudinal notch 62, and maintains
the
CA 02832029 2013-10-31
- 6 -
door jamb member 30 and the frame member 32 in a parallel relationship.
Additionally, when engaged in this manner, the biased, longitudinal clip
member 42
engages the longitudinal groove 52 so as to secure the frame member 32 and the
door
jamb member 30 to each other. In this embodiment, the frame member 32 and the
door jamb member 30 are further secured to each other by glue disposed between
the
rounded longitudinal edge 50 and the rounded channel 40.
[00032] The corner key 24 may be better seen in Figures 3 and 4. Each
corner
key 24 is a discrete and separate part from the door jamb portion 22. In this
embodiment, each corner key 24 is fabricated of glass-filled nylon by
injection
molding. Each corner key 24 is generally shaped to engage the internal
cavities 34,
36 and 38 of two (2) door jamb members 30, so as to form a generally ninety
(90)
degree, or a generally "right-angled", joint between two (2) door jamb
portions 22.
Each corner key 24 comprises a first panel 70 and a second panel 72 that are
connected along a common edge, and which are oriented generally orthogonally
to
each other. The first and second panels 70 and 72 are supported in relation to
each
other by gussets 74, and by a first end panel 76 and a second end panel 78. A
set of
pins extends outwardly from each of the first and second panels 70 and 72. In
the
embodiment shown, each set of pins comprises a first pin 82, a second pin 84
and a
third pin 86 extending from each of the first and second panels 70 and 72, and
which
are sized and positioned to engage the first internal cavity 34, the second
internal
cavity 36 and the third internal cavity 38, respectively, of the door jamb
member 30.
The corner key 24 further comprises a cap pin 88 extending from the first end
panel
76, which is sized and positioned to cover the channels 54 and interior
cavities 92,
when the corner key 24 connects the two (2) door jamb portions 22.
1000331 In use, the door jamb assembly 20 is assembled by providing two
(2)
corner keys 24 and three (3) door jamb portions 22, and namely two (2) door
jamb
portions 22 having a first length and one (1) door jamb portion 22 having a
second
length, the first length being greater than the second length. In this
embodiment, each
door jamb portion 22 is provided with the door jamb member 30 already secured
to
the frame member 32. Each end of the door jamb portion 22 having the second
length
is then connected to a corresponding end of a door jamb portion 22 having the
first
length using a corner key 24. In particular, adjacent door jamb portions 22
are
CA 02832029 2013-10-31
- 7 -
connected by inserting a first pin 82, a second pin 84 and a third pin 86 of
the corner
key 24 into the first internal cavity 34, the second internal cavity 36 and
the third
internal cavity 38, respectively, of each adjacent door jamb portion 22. Once
assembled, the assembled door jamb assembly may then be installed in a
suitably-
sized doorway opening in a wall, such that the one (1) door jamb portion 22
having
the second length is oriented generally horizontally as a "header" and the two
(2) door
jamb portions 22 having the first length are oriented generally vertically.
1000341 Figure 6 shows the door jamb assembly 20 installed in a doorway
opening of a wall 92. Hinges (not shown) and lock set recesses (not shown)
have
been added to the frame members of the vertically-oriented door jamb portions
22 for
accommodating a door D.
1000351 Figure 7 shows the door jamb portion 22 of the door jamb assembly
20
installed in another embodiment of a doorway opening of an exterior wall of a
building, such as for example a house. As may be seen, the door jamb member 30
and the frame member 32 are positioned generally adjacent an inner surface 93
of a
frame 94 surrounding the doorway opening. As may be seen, trim in the form of
a
longitudinal brick mold portion 95 is accommodated by the longitudinal channel
51,
for generally finishing the joint between the door jamb portion 22 and an
exterior
surface 96 of the doorway opening frame 94 and a surface of an exterior brick
wall
97. Additionally, in the embodiment shown, a reinforcement member in the form
of a
bar 98 having a "C"-shaped cross-sectional profile is accommodated by the
channel
46, for generally providing reinforcement to the door jamb portion 22.
1000361 As will be appreciated, the "bullnose" joint formed between the
rounded longitudinal edge 50 of the frame member 32 and the rounded channel 40
of
the door jamb member 30 is strong, and is simple in design and may
advantageously
be fabricated at a low cost. Moreover, the inherent strength of the "bullnose"
joint
advantageously eliminates the need for additional fasteners between the door
jamb
member 30 and the frame member 32, such as for example screws. Additionally,
the
rounded longitudinal edge 50 can advantageously be formed in a facile manner,
and
without forming burrs or surface roughness that might otherwise occur during
formation of non-rounded edges by machining. As will be understood, the
absence of
burrs or surface roughness advantageously ensures a secure fit between the
rounded
CA 02832029 2013-10-31
- 8 -
channel 40 and the rounded longitudinal edge 50. Additionally, and as will be
understood, the rounded longitudinal edge 50 does not have longitudinal
corners or
edges that would otherwise be likely to tear or chip upon insertion into a
receiving
channel of a member fabricated of non-wooden material.
1000371 As will be appreciated, the corner key 24 is configured to join
two (2)
door jamb portions 22 without requiring the ends of the door jamb portions 22
to be
cut to a specific angle, other than the 90 degree angle formed during
manufacture of
the door jamb member 30. As will be appreciated, this eliminates the need to
modify
the ends of the door jamb portions 22, such as for example by cutting an end
to a 45
degree angle by miter saw, during on site assembly of the door jamb assembly
20.
This allows the door jamb assembly 20 to be assembled from "stock" or
unmodified
parts, which advantageously reduces the cost of assembly of the door jamb
assembly
20, and which advantageously allows parts that may have been damaged during
transport or during assembly to be easily replaced.
1000381 Other configurations are possible. For example, Figures 8 to 11
show
another embodiment of a door jamb assembly, which is generally indicated by
reference numeral 120. Door jamb assembly 120 is configured to be installed in
a
doorway opening of an exterior wall of a building for accommodating a door D
and a
sidelight panel S. The door jamb assembly 120 comprises three (3) door jamb
portions 22, namely two (2) door jamb portions 22 configured to be oriented
generally
vertically and one (1) door jamb portion 22 configured to be oriented
generally
horizontally as a "header", that are connected by two (2) corner keys 24. In
this
embodiment, each door jamb portion 22 comprises an extruded, longitudinal door
jamb member 30 and a longitudinal frame member 32, as described above and with
reference to Figures 1 to 6. As may be seen, the header door jamb portion 22
is sized
to extend generally the widths of the door D and the sidelight panel S.
1000391 The door jamb assembly 120 also comprises a door frame post 150
that
is configured to be fastened to the header door jamb portion 22. The door
frame post
150 may be better seen in Figures 9a and 9b. The door frame post 150 comprises
an
extruded, longitudinal post member 152 and a longitudinal frame member 154. In
this embodiment, the post member 152 is fabricated of PVC "cap stock", and is
formed by co-extrusion of recycled (or "regrind") PVC and new PVC so as to
provide
CA 02832029 2013-10-31
- 9 -
a body of recycled PVC that is coated with layer of new PVC, as is known in
the art.
The post member 152 comprises a plurality of longitudinal internal cavities,
which
extend the length of the post member 152 and which are separated by
longitudinal
internal webs. In the embodiment shown, the post member 152 comprises a first
cavity 156 and a second cavity 158.
1000401 The post member 152 also comprises a plurality of longitudinal
external channels extending the length thereof In the embodiment shown, the
post
member 152 comprises a central channel 162 that is configured to engage the
frame
member 154, as described below. The post member 152 also comprises two (2)
biased, longitudinal clip members 164, each clip member 164 being disposed
along a
respective side of the central channel 162. Additionally, the post member 152
comprises two (2) longitudinal channels 166, with each channel 166 being
disposed
adjacent the central channel 162 and being configured for accommodating
weather
stripping.
[00041] The post member 152 is configured to accommodate one or more
longitudinal filler strips 170, with each filler strip 170 being inserted into
a cavity 156
or 158. Each filler strip 170 is sized to have at least one cross-sectional
dimension
that is generally commensurate with a cross-sectional dimension of the cavity
156 or
158, for enabling each filler strip 170 to be inserted into the cavity 156 or
158 in a
press fit manner. In the embodiment shown, the filler strips 170 are sized
such that
each cavity 156 and 158 accommodates two (2) filler strips 170 inserted
therein, as
may be seen in Figure 13b.
[00042] The filler strip 170 may be better seen in Figures 10 and 11. Each
filler strip 170 is formed by extrusion and is formed separately from the post
member
152, and in this embodiment each filler strip 170 is formed of extruded PVC.
Each
filler strip 170 comprises a plurality of longitudinal cavities 172 extending
the length
thereof, each being sized for receiving one or more fasteners at one or both
ends for
assembly of the door jamb assembly 120.
1000431 In this embodiment, the frame member 154 is formed by machining a
longitudinal wooden board. The frame member 154 comprises a shaped
longitudinal
portion 182 extending along a longitudinal side 184 thereof, and two (2)
longitudinal
grooves 186, with each longitudinal groove 186 being disposed along a
respective
CA 02832029 2013-10-31
- 10 -
side adjacent the longitudinal portion 182. The longitudinal portion 182 and
the
central channel 162 of the post member 152 are configured to matingly engage
so as
to form a butt joint therebetween. When engaged in this manner, the biased,
longitudinal clip members 164 engage the longitudinal grooves 186 for securing
the
frame member 154 and the post member 152 together. In this embodiment, the
frame
member 154 and the post member 152 are further secured to each other by glue
disposed between the longitudinal portion 182 and the central channel 162.
1000441 In use, the door jamb assembly 120 is assembled by providing the
two
(2) corner keys 24 and the three (3) door jamb portions 22, and namely the two
(2)
door jamb portions 22 configured to be oriented generally vertically and the
one (1)
header door jamb portion 22 configured to be oriented generally horizontally.
In this
embodiment, each door jamb portion 22 is provided with the door jamb member 30
already secured to the frame member 32. Each end of the header door jamb
portion
22 is then connected to a corresponding end of a door jamb portion 22
configured to
be oriented generally vertically using a corner key 24, in the manner
described above
for door jamb assembly 20 and with reference to Figures 1 to 6.
[000451 In this embodiment, the door frame post 150 is provided with the
post
member 152 already secured to the frame member 154, and with the filler strips
170
already inserted into the cavities 156 and 158.
1000461 The door frame post 150 and the header door jamb portion 22 are
then
fastened together using fasteners, and in this embodiment the fasteners are
screws.
Specifically, and with reference to Figure 2b, the door frame post 150 and the
header
door jamb portion 22 are fastened together by abutting an end of the door
frame post
150 against a side of the header door jamb portion 22 at a suitable position
intermediate its longitudinal ends, and: inserting at least one fastener
through the
longitudinal guide groove 45 and through the door jamb portion 22 into an
aperture
172 of the filler strip 170 positioned in the second cavity 158 of the post
member 152,
which causes the filler strip 170 to expand within the second cavity 158 and
to
thereby become compressively secured to the post member 152; and/or by
inserting at
least one fastener through the longitudinal guide groove 47 and through the
door jamb
portion 22 into an aperture 172 of the filler strip 170 positioned in the
first cavity 156
of the post member 152, which causes the filler strip 170 to expand within the
first
CA 02832029 2013-10-31
- 11 -
cavity 156 and thereby become compressively secured to the post member 152.
The
assembled door jamb assembly 120 may then be installed within a doorway
opening
in a wall, such that the two (2) door jamb portions 22 and the door frame post
150 are
oriented generally vertically and the one (1) header door jamb portion 22
fastened to
the door frame post 150 is oriented generally horizontally.
1000471 As will be appreciated, the door frame post 150 may be connected
to a
single, continuous header for providing suitable framing for both a door and a
sidelight, and advantageously provides a simpler construction approach as
compared
to conventional door frame assemblies comprising posts, for which a separate
box/enclosure for each door and panel is generally required to be constructed
within a
larger frame. Further, and as will be understood, an opposite end of the door
frame
post 150 may be connected to a single, continuous sill (not shown) for further
providing suitable framing for both the door and the sidelight.
1000481 As will be appreciated, the similarity in cross-sectional sizes of
the
filler strips and the internal cavities 156 and 158 advantageously results in
an increase
in the rigidity of the post member 152 when the filler strip 170 is caused to
expand
within the cavity 156 or 158 upon insertion of one or more fasteners during
fastening,
which thereby provides internal reinforcement for the door frame post 150.
[00049] It will be understood that door frame post is not limited to use
with the
door jamb portions described above, and in other embodiments, the door frame
post
may alternatively be used with a door frame assembly comprising door jamb
portions
each having a different cross-sectional profile than that of the door jamb
portion
described above, and/or comprising a header having a different cross-sectional
profile
than that of the header door jamb portion described above.
[00050] Although in the embodiment described above, the door jamb assembly
is configured for accommodating a door D and a sidelight panel S, in other
embodiments, other configurations are possible. For example, in other
embodiments,
the panel may be a panel other than a sidelight panel. In still other
embodiments, the
door jamb assembly may alternatively comprise more than one (1) door frame
post,
and the door jamb assembly may alternatively be configured for accommodating
more
than one (1) panel, and/or more than one (1) door. In one such embodiment, the
door
CA 02832029 2013-10-31
- 12 -
jamb assembly comprises two (2) doors arranged in a double door configuration,
with
the door frame post mounting to one of the doors to provide an astragal
configuration.
1000511 Although in the embodiment described above, the door frame post is
provided with the post member already secured to the frame member, in other
embodiments, the post member and the frame member may alternatively be cut on
site
to a suitable size, and then secured to each other on site to provide the door
frame
post.
1000521 Although in the embodiment described above, the post member is
fabricated of polyvinyl chloride (PVC) "cap stock", in other embodiments, the
post
member may alternatively be fabricated of virgin PVC, recycled PVC, or of any
other
suitable extrudable polymer. In still other embodiments, the post member may
alternatively be fabricated of extruded aluminum, extruded aluminum alloy, or
pulltruded fiberglass composite.
[00053J Although in the embodiment described above, the frame member is
formed by machining a longitudinal wooden board, in other embodiments, the
frame
member may alternatively be formed by machining a longitudinal board of
another
material, such as for example, plywood, medium-density fibreboard (MDF),
particle
board, PVC, foamed PVC, or a PVC composite material comprising one or more of
wood, flour and rice.
[000541 It will be understood that the cross-sectional profile of the post
member is not limited to that of the embodiment described above, and in other
embodiments, the post member may alternatively have a different cross-
sectional
profile. For example, the post member may alternatively have a different
configuration of longitudinal internal cavities and longitudinal channels. As
an
example, in other embodiments, the post member may alternatively comprise only
a
one (1) longitudinal internal cavity configured for accommodating one or more
filler
strips, or alternatively may comprise more than two (2) longitudinal internal
cavities
each configured for accommodating one or more filler strips. It will also be
understood that the cross-sectional profile of the frame member is not limited
to that
of the embodiment described above, and in other embodiments, the frame member
may alternatively have a different cross-sectional profile.
CA 02832029 2013-10-31
- 13 -
[00055] Although in the embodiment described above, the longitudinal
internal
cavities and the longitudinal channels of the post member extend the length of
the
post member, in other embodiments, at least one of the longitudinal internal
cavities
and/or at least one of the longitudinal channels may alternatively not extend
