Crown molding member having planar portion, intermediate portion, and mounting flange
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.

This application is a continuation of U.S. patent application Ser. No. 10/774,798, which was filed on Feb. 9, 2004, and which was published on Sep. 8, 2005, as United States Patent Application No. US 2005/0193664 A1.
TECHNICAL FIELD OF THE INVENTIONThis invention pertains to a crown molding member, of a type used to trim an interior corner defined where a wall and a ceiling meet. This invention contemplates that the crown molding member has a mounting flange, to which drywall-finishing material, so-called “mud” in trade parlance, is applicable.
BACKGROUND OF THE INVENTIONA crown molding member of the type noted above is exemplified in U.S. Pat. Nos. 6,477,818 B1 and No. 6,643,990 B2, which disclose that an upper, horizontal, “alignment” portion of the crown molding member is attached adhesively to a ceiling panel, via a tape coated on both sides with an adhesive, that a back edge of the upper, horizontal, “alignment” portion abuts a wall panel but is not attached to the wall panel, and that a lower edge of an angled face of the crown molding member abuts the wall panel but is not attached to the wall panel.
SUMMARY OF THE INVENTIONThis invention provides a crown molding member, which is useful to trim a corner defined where a vertical wall and a horizontal ceiling meet and which is installable in two modes. Broadly, the crown molding member has a pair of spaced, planar, mounting flanges extending normal to each other, one said flange to extend along the horizontal ceiling and the other flange to extend along the vertical wall, when the crown molding member is installed.
Preferably, one said flange extends toward the corner, when the crown molding is installed. Preferably, moreover, one said flange extends toward the corner and the other flange extends away from the corner, when the crown molding is installed. Preferably, said one flange extending toward the corner extends from the intermediate portion to proximal the corner, when the crown molding member is installed.
Preferably, the flange extending along the horizontal ceiling is attached to the horizontal ceiling, when the crown molding member is installed. Preferably, the flange extending along the vertical wall is attached to the vertical wall, when the crown molding member is installed. Preferably, moreover, the flange extending along the horizontal ceiling is attached to the horizontal ceiling and the flange extending along the vertical wall is attached to the vertical wall, when the crown molding member is installed.
BRIEF DESCRIPTION OF THE DRAWINGS
As illustrated in
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.
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.

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.

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.

As illustrated in
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.
Claims
1. A crown molding member, which is useful to trim a corner defined where a vertical wall and a horizontal ceiling meet, the crown molding member having a pair of spaced, planar, mounting flanges extending normal to each other, one said flange to extend along the horizontal ceiling and the other flange to extend along the vertical wall, when the crown molding member is installed.
2. The crown molding member of claim 1, wherein one said flange extends toward the corner, when the crown molding is installed.
3. The crown molding member of claim 2, wherein the other flange extends away from the corner, when the crown molding is installed.
4. The crown molding member of claim 2, wherein said one flange extending toward the corner extends from an intermediate portion to proximal the corner, when the crown molding member is installed.
5. The crown molding member of claim 3, wherein said one flange extending toward the corner extends from an intermediate portion to proximal the corner, when the crown molding member is installed.
6. The crown molding member of any one of claims 1 through 5, wherein the flange extending along the horizontal ceiling is attached to the horizontal ceiling, when the crown molding member is installed.
7. The crown molding member of any one of claims 1 through 5, wherein the flange extending along the vertical wall is attached to the vertical wall, when the crown molding member is installed.
