Crown molding member having planar portion, intermediate portion,
and mounting flange
Abstract
As used to trim a corner where a wall and a ceiling meet, a
crown molding member has a planar portion, an intermediate portion,
and a mounting flange. The planar portion is attached to the
ceiling, in a first mode, or to the wall, in a second mode. The
intermediate portion may have a coved, stepped, or curved profile.
When applied to the mounting flange, drywall-finishing material,
so-called "mud" in trade parlance, is pressed through apertures in
the mounting flange, against the wall, in the first mode, or
against the ceiling, in the second mode.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS
[0014] As illustrated in FIG. 1, a crown molding member 10
embodying this invention has a planar portion 20, which has a
distal edge 22 and a proximal edge 24, an intermediate portion 30,
which has a distal edge 32 adjoining the distal edge 22 of the
planar portion 20 and which has a proximal edge 34, which is spaced
from the distal edge 32 of the intermediate portion 30, a mounting
flange 40 having an adjoining edge 42 adjoining the distal edge 34
of the intermediate portion 30, an additional flange 50 having an
adjoining edge 54 adjoining the proximal edge 24 of the planar
portion 20, and a flexible fin 60 projecting from the intermediate
portion 30, near the distal edge 32 of the planar portion 30.
[0015] The intermediate portion 30 may have a coved, curved, or
stepped profile or an arbitrary profile. A step 44 is defined where
the adjoining edge 42 of the mounting flange 40 adjoins the
proximal edge 34 of the intermediate portion 30. The mounting
flange 40 has an array of apertures 46, such as circular holes,
which are illustrated, or such as elongate slots. The flexible fin
60 is co-extruded with the other portions of the crown molding
member 10.
[0016] Preferably, except for the flexible fin 60 and except for a
so-called "living" hinge, if provided, as discussed below, the
crown molding member 10 is extruded so as to have a substantially
uniform thickness of approximately 0.060 inch to approximately
0.070 inch, except as discussed below. Preferably, the flexible fin
60 and the other portions of the crown molding member are
co-extruded, the flexible fin 60 being extruded from a
comparatively softer, more flexible, polymeric material, such as
polyvinyl chloride having a hardness of Durometer 92 Shore A and
the other portions of the crown molding member 10 being extruded
from a comparatively harder, less flexible, polymeric material,
such as polyvinyl chloride having a hardness of Durometer Shore 82
D.
[0017] As illustrated in FIG. 2, the crown molding member 10 is
installed in a first mode, so as to trim an interior corner where a
wall 100 and a horizontal ceiling 200 meet. The vertical wall 100
and the horizontal ceiling 200 are defined by drywall panels having
gypsum cores and having paper faces. Thus, the planar portion 20
extends horizontally, beneath and along the horizontal ceiling 200,
to which the planar portion 20 is attached. In a preferred
implementation via an adhesive means 70, such as a sprayed adhesive
or a double-faced, adhesive tape. Trim-Tex 847.TM. Spray Adhesive,
which is available commercially from Trim-Tex, Inc. of Lincolnwood,
Ill., is a preferred means.
[0018] As illustrated in FIG. 2, the proximal edge 24 of the planar
portion 20 is proximal to the vertical wall 100. Also, the
additional flange extends along the vertical wall, toward the
mounting flange. Also, the mounting flange 40 extends downwardly,
along the vertical wall 100, away from the horizontal ceiling 200.
Moreover, the additional flange 50 extends downwardly, beside and
along the vertical wall 100, toward the mounting flange 40.
Moreover, the flexible fin 60 bears upwardly against the horizontal
ceiling 200, so as to close a pocket 62 formed where the distal
edge 32 of the intermediate portion 30 adjoins the distal edge 22
of the planar portion 20.
[0019] Furthermore, this contemplates that, when the crown molding
member 10 is installed in the first mode when drywall-finishing
material 80, the mounting flange 40 is attached to the vertical
wall 100 via mechanical fasteners 80, such as wire staples with
diverging legs, one such staple being shown. Moreover, when
drywall-finishing material 90, so-called "mud" in trade parlance,
is applied to the mounting flange 40, some of the applied material
90 can be then pressed through at least some of the apertures 46,
against the vertical wall 100. The step 44 facilitates spreading of
such material 90 with a drywall-finishing blade.
[0020] As illustrated in FIG. 4, the crown molding member 10 is
installed in a second mode, so as to trim the interior corner where
the vertical wall 100 and the horizontal ceiling 200 meet. Thus,
the planar portion 20 extends downwardly, beside and along the
horizontal wall 100, to which the planar portion 20 is attached via
the adhesive means 70. Also, the proximal edge 24 of the planar
portion 20 is proximal to the wall 100. Moreover, the additional
flange 50 extends downwardly, beside and along the vertical wall
100, toward the mounting flange 40. Moreover, the flexible fin 60
bears laterally against the vertical wall 100, so as to close a
pocket 62 formed where the distal edge 32 of the intermediate
portion 30 adjoins the distal edge 22 of the planar portion 20.
[0021] Furthermore, this invention contemplates that, when the
crown molding member 10 is installed in the second mode, the
mounting flange 40 is attached to the horizontal ceiling 200 via
mechanical fasteners 80, such as wire staples with diverging legs,
one such staple being shown. Moreover, when drywall-finishing
material 90, so-called "mud" in trade parlance, is applied to the
mounting flange 40, some of the applied material 90 can be then
pressed through at least some of the apertures 46, against the
horizontal ceiling 200. The step 44 facilitates spreading of such
material 90 with a drywall-finishing blade.
[0022] As illustrated in FIG. 5, the crown molding member 10 is
installed in the first mode, in a second implementation differing
from other implementations of the first mode, as discussed herein,
in that the planar portion 20 is attached to the horizontal ceiling
200 via mechanical fasteners 80, such as wire staples with
diverging legs, one such staple being shown. As illustrated in FIG.
7, the crown molding member 10 is installed in the first mode, in a
third implementation differing from other implementations of the
first mode, as discussed herein, in that the additional flange 50
is attached to the vertical wall 100 via mechanical fasteners 80,
such as wire staples with diverging legs, one such staple being
shown. As illustrated in FIG. 7, the additional flange 50 is
lengthened so as to accommodate such fasteners 80. In the second or
third implementation of the second mode, the planar portion 20 may
be also attached adhesively to the horizontal ceiling 200, as
described above.
[0023] As illustrated in FIGS. 5, 6, and 7, so as to facilitate
flexing of the crown molding member 10 for entry of a
fastener-driving tool, the crown molding member 10 is thinner, as
compared to the generally uniform thickness discussed above, so as
to form a so-called "living" hinge 12 where the distal edge 32 of
the intermediate portion 30 adjoins the distal edge 22 of the
planar portion 20. As illustrated in a broken line in FIG. 6, a
caulk bead 14 may be optionally applied along crown molding member
10, where the so-called "living" hinge 12 is formed, so as to
adhere to the horizontal ceiling 200, after the crown molding
member 10 has been installed in the second or third implementation
of the second mode.
[0024] As illustrated in FIG. 8, the crown molding member 10 is
installed in the first mode, in a fourth implementation differing
from other implementations of the first mode, as discussed herein,
in that a caulk bead 14 is applied along the crown molding member
10, where the distal edge 32 of the intermediate portion 30 adjoins
the distal edge 22 of the planar portion 20, so as to adhere to the
horizontal ceiling 200, after the crown molding member 10 has been
installed. In the fourth implementation of the second mode, the
planar portion 20 may be also attached adhesively to the horizontal
ceiling 200, as described above.
[0025] As illustrated in the drawings and described herein, the
first mode in its various implementations is differentiated from
the second mode because of the rotational orientation of the crown
molding member 10 relative to an imaginary axis, which is parallel
to the vertical wall 100 and to the horizontal ceiling 200.
