Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims the benefit under 35 U.S.C. 119 (e)
of U.S. Provisional Application No. 60/571,979 filed on May 17,
2004, which is hereby incorporated by reference in its
entirety.
FIELD
[0002] This application relates generally to building products and
more specifically to a window or door trim.
BACKGROUND
[0003] Trim is applied around windows and doors to protect the
windows and doors and for aesthetic reasons. Typically, trim
includes a wood strip nailed to the sheathing around the window to
mount the trim to the window. Wood is susceptible to warp, rot, and
requires frequent repainting. Moreover, trim can be difficult to
mount in the space around a window or door. What is needed is trim
product to improve on the disadvantages and weaknesses of
traditional trim.
SUMMARY
[0004] In one aspect, a trim system includes a base member for
mounting to a structure and a cover member adapted to be snap-fit
to the base member. In some embodiments, the base member and the
cover member can be pultruded.

[0008] FIG. 4 shows a cross-section view of a cover member in
accordance with one embodiment.
DETAILED DESCRIPTION
[0009] In the following detailed description, reference is made to
the accompanying drawings which form a part hereof, and in which is
shown by way of illustration specific embodiments in which the
invention may be practiced. These embodiments are described in
sufficient detail to enable those skilled in the art to practice
the invention, and it is to be understood that the embodiments may
be combined or that other embodiments may be utilized and that
structural changes may be made without departing from the spirit
and scope of the present invention. The following detailed
description is, therefore, not to be taken in a limiting sense, and
the scope of the present invention is defined by the appended
claims and their equivalents.
[0010] FIG. 1 shows a cross-section, profile view of a trim system
100 according to one embodiment. In this example, trim system 100
is mounted to a structure 142 and applied around a window 130. In
other examples, the trim can be applied around a door. Trim system
100 includes a base member 110 and a cover member 120. In this
example, the base member 110 and cover member 120 define a
two-piece brickmold trim system for doors or windows.
[0011] Base member 110 can be used as a flashing piece that can be
installed directly over a nailing fin 132 of window 130. Base
member 110 includes a back wall 112 and a top wall 114. Back wall
112 includes a planar surface that is mounted flush against
structure 142. Cantilevered from back wall 112 is a mounting
section 116.
[0012] Cover member 120 is snap-fit to base member 110. Base member
110 and cover member 120 can be formed of vinyl, metal, or
pultrusion, in some examples. By providing a snap-fit structure,
system 100 allows for relatively easy installation. For example,
base member 110 can be mounted to the structure using nails or
adhesive, then cover member 120 is snapped into place over the base
member.
[0013] FIGS. 2 and 3 show further details of base member 110 and
cover member 120, respectively. Base member 110 can include a
constant cross-section profile, such as an approximate L-shape
profile 201 defined by a long leg (wall 112) and a short leg (wall
114). At an end 202 of the short leg of the L-shape, base member
110 includes a mounting section 204. Top wall 114 can be very short
or long depending on the design. In this example, mounting section
204 includes a projecting lip 206 that extends from the top of the
base member perpendicular to wall 114.
[0014] Cover member 120 includes a corresponding U-shaped mounting
section 304 that is dimensioned to matingly fit around lip 206.
Cover member 120 can include a constant cross-section profile 301
and can include a pultruded profile, for example. The cover member
120 can be formed with aesthetic features such as curls 314, ridges
316, grooves, etc, exposed on the outer, exposed surface of the
cover member. The cover member 120 can be virtually any color or
shape. The cover member 120 is adapted to engage in a snap-fit
frictional engagement with base member 110. Snap-fit mounting means
that the cover member 120 is held in place through the use of force
via the flexing of wall 114, wall 312, a projection 208, and/or
wall 310 and the subsequent holding action of an upper ridge 210 of
projection 208 and a lip 206 of wall 114.
[0015] Base member 110 also includes second mounting section 116
located and projecting from back wall 112 of the L-shaped profile.
Mounting section 116 is oriented approximately perpendicular
relative to mounting section 204. Mounting section 116 includes a
projecting portion 208 having upper ridge 210. Cover member 120
includes first wall 310 and perpendicular wall 312, which is
cantilevered and dimensioned to engage ridge 210 on base member
110. Cover member 120 includes a corresponding mounting section 306
that includes a cavity 308 that engages ridge 210 during the
snap-fit engagement.
[0016] The present design can help reduce water intrusion while
giving nailing fin accessibility. For example, base member 110
includes an exposed surface 144, which is exposed when attaching
the base member 110 to structure 142. Surface 144 is easily
accessible to allow a worker to mount base member 110 to structure
142 (FIG. 1) by driving nails, screws, staples, etc through surface
144 and into the structure. Base member 110 can be mounted to
sheathing or the frame itself, and to the rough opening of the
window. Accordingly, the trim system is easy to install because it
allows easy access for nailing fin accessibility.
[0017] Referring again to FIG. 1, to mount trim system 100 around a
door or window, base member 110 is attached to either the sheathing
of structure 142 or directly to the frame of the structure. If base
member 110 is made of metal, slots can be provided in the base
member and the base member can be loosely hung on nails attached to
the structure and extending through the slots. If the base member
110 is made of a pultrusion, the base member can be directly
mounted to the frame of the structure. Cover 120 is then snap-fit
to the base member 110. To snap-fit the cover member, U-shaped
mounting section 304 is fit to lip 206. Then the cover is swung
toward the base member until cavity 308 engages ridge 210. As noted
above, the force via the flexing of wall 114, wall 312, projection
208, and/or wall 310 and the subsequent holding action of upper
ridge 210 and lip 206 holds the cover member in place.
[0018] Before or after the trim system is installed, siding can
then be added to the structure. One embodiment uses a pultruded
siding system such as disclosed in co-pending U.S. application Ser.
No. 11/032,315, filed Jan. 10, 2005, which is incorporated herein
by reference.
[0019] FIG. 4 shows another example of a cover member 420, in
accordance with one embodiment. Cover member 420 includes mounting
section 304 and mounting section 306, similar to cover member 120.
The profile shape of cover member 420 is different than cover
member 120 and includes aesthetic features, such as grooves 422,
for example. Other embodiment can provide virtually any profile
having aesthetic features as desired.
[0020] As noted above, some embodiments utilize pultrusion for the
trim system 100. This is advantageous since both vinyl and long
member metal products need to be slotted when attached to the
sheathing of a home because of their high coefficient of thermal
expansion. They have to be carefully nailed in the slots in a
manner that allows horizontal movement of the siding as the
temperature changes. Warping due to this large CTE is one of the
chief drawbacks to these types of siding.
[0021] However, if pultruded, base member 110 can be mounted
directly to the structural frame or the window roughing. This can
eliminate the need for the sheathing of typical construction.
Moreover, if pultruded, trim members 110, and 120 are not be
susceptible to warping due to expansion or softening at elevated
temperatures such as vinyl or metal siding. Moreover, they allow
for the elimination of installation slots, which makes the product
easier to install, requiring less time and labor. Also, the
pultruded members could also be installed with any color.
[0022] Members 110 and 120 can be formed by pultrusion and can
include a coating or a film for additional protection from elements
or ultraviolet protection. For example, the pultrusion and coating
can be as described in commonly assigned U.S. Pat. No. 6,197,412,
which is incorporated herein by reference in its entirety. Members
110, 120 can be various heights, for example, from a few inches to
a foot. They can have lengths of up to 10 feet or longer.
[0023] Moreover, since the pultruded members have a relatively high
insulative property, they help the insulating value of a structure
wall and are less likely to be condensation points for
moisture.
[0024] In some embodiments, base and cover member 110 and 120 can
be pultruded and formed as composite parts. For example, glass, or
other reinforcing fibers, are impregnated with resin and pulled
through a forming guide and a heated die. The forming guide orients
the fibers to be properly placed in the heated die to insure that
the pultruded part has uniform reinforcement across its shape. The
heated die cures and/or solidifies the resin around the reinforcing
fibers, thus forming the composite part. The composite part, having
a profile shape, is continuously pulled out of the heated die by a
puller. The puller can be a clamp and stroke action from a
reciprocating puller, or a smooth action from a caterpillar
puller.
[0025] Reinforcing fibers used in the example pultrusions can be
glass, carbon fiber, kevlar, and other organic and inorganic
filaments and fibers. Reinforcement fibers can take the form of
filament and strand bundles, called rovings. They also take the
form of yarns, texturized yarns, chopped strand mats, continuous
strand mats, knitted mats, woven mats, surfacing veils, and many
hybrid combinations of rovings, yarns, mats, and veils.
[0026] Resin used in example pultrusions can be thermosetting
resins like unsaturated polyesters in a styrene solution, or
polyurethanes, phenolics, epoxides, thermosetting blends, and other
thermosetting resins. Other resins used in pultrusion can be
thermoplastic resins based on polyurethanes, acrylics,
polyethylenes, and other thermoplastic resins. Resin used in
pultrusion can also be thermoplastic resins that are embedded in
rovings that melt and form the part inside the pultrusion die.
[0027] Resin mixtures in pultrusion can also contain organic,
polymeric, and inorganic additives for such properties as shrink
control, mold lubrication, colorants, fillers and other specially
additives.
[0028] In some embodiments, the base member 110 can be incorporated
into the window frame itself. Accordingly, the window would have a
built-in flashing. In other words, the flashing piece 110 can
replace the nailing fin of the window. In such an example, after
the window is installed, only cover member 120 needs to be snap-fit
around the window to apply trim to the window.
[0029] In some embodiments, a gasket can be located in the joints
of the trim system. For example, referring to FIGS. 1-3 a gasket
material can be located between section 304 and 204, and a gasket
material can be located between section 308 and section 210.
[0030] The above description is intended to be illustrative, and
not restrictive. Many other embodiments will be apparent to those
of skill in the art upon reviewing the above description. The scope
of the invention should, therefore, be determined with reference to
the appended claims, along with the full scope of equivalents to
which such claims are entitled.
