ABSTRACT:
FIELD OF THE INVENTION
This invention relates to corner posts used in building, housing and other constructions, and more particularly to corner posts that provide an ornamented appearance to finished corners.
BACKGROUND OF THE INVENTION
Corner posts are frequently used to finish the corners on the exteriors of homes and businesses. They can be used to provided subtle details or more pronounced architectural details for a corner while providing an aesthetic cover for the ends of rows of siding panels attached to the walls of the structure. A beaded corner post typically provides the appearance of a beaded center area—an area with a relatively wide face and a rounded center protrusion—flanked by two side faces. Each side face may include, for example, an ornamental impression, such as a woodgrain finish. Each side face may also be fluted, or have a smooth, flat finish. The center area, rather than being beaded, may also include more detailed ornamental impressions and shapes, be cove shaped, and/or be any number of colors. The selected color need not be the same as the color of the siding panels attached to the structure or the side faces of the corner post.
FIG. 1

is attached to a corner

of a structure. A first nailing flange

is typically nailed to a first exterior face

of the corner

, and a second nailing flange

is typically nailed to a second exterior face

of the corner

. The beaded corner insert

includes a central beaded protrusion portion
20
which is rounded. After the beaded corner insert
2
is affixed to the corner

, mating portion
11
of a first side panel
10
(also referred to as a lineal) is fitted into an area
12
a
defined by the profile of beaded corner insert

. The side panel
10
is typically nailed to the first exterior face

through nailing flange
14
. The ends of the rows of siding panels (not to be confused with side panel
10
) that are attached to the structure terminate near the corner
4
and are disposed within and covered by J-channel
16
. The exterior face
18
of side panel
10
may include an ornamental impression as described above. A second side panel (not shown) is installed in a like manner by fitting the second side panel into area
12

defined by the profile of beaded corner insert
2
and by nailing the second side panel to exterior face
8

of corner
4
. The prior art corner system
1
of
FIG. 1
, therefore, includes three principal pieces—a beaded corner insert, a first side panel, and a second side panel. It should be understood that the exploded view of
FIG. 1
illustrates profile views of the components of a prior art beaded corner post system
1
and that each profile typically extends a length sufficient to cover the height of a corner
4
of a structure.
The prior art three-piece beaded corner post system
1
presents several problems. First, installation of the corner post system
1
requires the installation of three separate pieces—a corner insert
2
and two side panels
10
. Also, many customers, after some time has passed, wish to replace the beaded portion
20
of the corner system, either because of damage to the beaded portion
20
or for aesthetic reasons, e.g., to replace the beaded portion with a portion having a different aesthetic look and/or a different color. Replacement of the beaded portion
20
of the beaded corner system
1
necessarily requires removal of siding panels fitted within J-channel
16
, removal of the first and second side panels
10
attached to the corner
4
, and removal of beaded corner insert
2
, all followed by the complex re-installation of the three-piece beaded corner post system
1
having a replacement beaded corner insert
2
.
FIG. 2
is an exploded view illustrating a prior art four-piece beaded corner post system
30
. A starter section
36
is attached by a nailing flange
38
to a first exterior face
34
a
of corner
32
. A mating portion
41
of first side panel
40
is then fitted into area
42
a
defined by the profile of the starter section
36
, and the first side panel
40
is secured to first exterior face
34
a
by nailing flange
44
. The ends of the rows of siding panels (not to be confused with side panel
10
) that are attached to the exterior face
34
a
of a structure terminate near the corner
32
and are disposed within and covered by J-channel
46
included within side panel
40
. The exterior face
48
of side panel
40
may include an ornamental impression as described above in connection with the side panel
10
of
FIG. 1. A
second side panel (not shown) is installed in a like manner by fitting a mating portion of the second side panel into area
42
b
defined by the profile of the starter
36
and by nailing the second side panel to exterior face
34
b
of corner
32
. After the starter
36
and two side panels
40
are installed, a beaded corner insert
50
is fitted into areas
42
a
and
42
b
with mating portion
52
a
and
52
b
, respectively. Like beaded corner insert
2
, beaded corner insert
50
includes a central beaded protrusion portion
52
which is rounded. The prior art corner system
30
of
FIG. 2
, therefore, includes four principal pieces—a starter section, a first side panel, a second side panel, and a beaded corner insert. It should be understood that the exploded view of
FIG. 2
illustrates profile views of the components of a prior art beaded corner post system
30
and that each profile typically extends a length sufficient to cover the height of a corner
32
of a structure.
Although the prior art four-piece beaded corner post system
30
allows for easier replacement of the beaded corner insert
50
when compared with three-piece corner post system
1
, installation of the four-piece system
30
is even more labor and time intensive than the three-piece beaded corner post system
1
; namely, four separate pieces must be installed—a starter section
36
, a first and second side panels
46
and a corner insert
50
.
Therefore, there is a need for an ornamented corner post system which provides for a simplified installation process. Still further, there remains a need for an ornamented corner post system which allows for easy replacement of or modification of a central ornamented area of the corner post system.
SUMMARY OF THE INVENTION
A corner piece for covering a corner of a structure defined by two mating walls of the structure and for use in conjunction with siding panels attached to the mating walls includes an ornamented central portion having a first and second lateral edges and a first and second side walls. Each of the first and second side walls has an exterior face and an interior face. The first and second side walls are integrally formed with the ornamented central portion and extend from the first and second lateral edges, respectively. The first and second side walls cover a portion of the first and second mating walls of the structure, respectively, and overlap at least a portion of the siding panels when the siding panels and the corner piece are fastened to the structure. The corner piece provides for greatly simplified installation.
Also as described herein, a corner piece includes an ornamented central portion having a first and second lateral edges and a first and second side walls. The ornamented central portion is configured to receive a frictionally fitted ornamented cap. Each of the first and second side walls has an exterior face and an interior face. The first and second side walls are integrally formed with the ornamented central portion and extend from the first and second lateral edges, respectively. The first and second side walls cover a portion of the first and second mating walls of the structure, respectively, and overlap at least a portion of the siding panels when the siding panels and the corner piece are fastened to the structure. The corner piece, in addition to providing for simplified installation, a
