BACKGROUND
It is standard practice to use baseboard moldings along the intersection of the floor and wall in residential and commercial construction. Similarly, cornice moldings are used at the intersection of the ceiling and walls. Crown moldings similarly cover the intersection of the ceiling and wall, but cover a narrow strip of the ceiling left uncovered by the cornice molding.
Where a 90-degree inside or outside corner is caused by the intersection of two adjacent walls, it is the well-known and established practice to miter-cut the adjacent molding strips to result in an end surface at 45-degrees to the length of the molding. With the surfaces cut at 45-degrees and positioned adjacent to each other, the molding strips form the required 90-degree angle. While this practice works well in theory, it is frequently the case that the workmanship of actual application contains visible flaws.
It is even more difficult to apply moldings to rounded “barrel” or “bull nose” corners. Such corners tend to lend a polished, classy look to new construction. However, the appearance is degraded by moldings which do not conform to the curvature of the wall. Since the wall is curved, it is common practice to cut short segments of straight molding and approximate the rounded corner corner. The use of short segments results in a number of seams defined between adjacent segments. This is unattractive, and detracts from the appearance of the molding.
This problem arises on both inside and outside corners, and with both baseboard molding on the floor and with cornice and crown molding on the ceiling.
For the foregoing reasons, there is a need for miterless molding system for angular and rounded inside and outside corners that results in a smooth, professional appearance in rounded-corner applications.
SUMMARY
The present invention is directed to an apparatus that satisfies the above needs. A novel miterless molding system for rounded inside and outside corners is disclosed that is adapted for use with cornice moldings, crown moldings, baseboard and other types of moldings. The molding system for rounded corners provides a flush, seamless connection about an inside or outside rounded corner, and mates to the straight segment portions of existing types of moldings.
The miterless molding corner piece
10
adapted for use on rounded inside or outside corners of the present invention provides some or all of the following structures.
(A) A curving segment
30
having an inside surface
33
defined to conform to the outside surface of a bull nose, barrel or similar rounded corner
300
of a wall surface. The inside surface may be defined to fit a corner of almost any angle, but is typically 90 degrees (i.e. an inside corner) or 270 degrees (i.e. an outside corner). The corner piece also defines an outside profiled surface
36
configured to conform to the profiled surface
401
,
501
of adjacent straight molding segments.
(B) In a preferred version, first and second straight segments
70
,
80
extend from the first and second ends
34
,
35
of the curving segment
30
. The first and second straight segments have inside surfaces
72
,
82
defined to conform to first and second flat wall surfaces
100
,
200
and have profiled surfaces
73
,
83
configured to conform to the profiled surfaces of the first and second molding segments
400
,
500
carried by the wall surfaces.
It is therefore a primary advantage of the present invention to provide a novel miterless molding system for rounded inside and outside corners that makes a seamless transition from the segments of straight molding carried by adjacent wall surfaces about a rounded corner.
Another advantage of the present invention is to provide a novel miterless molding system for rounded inside and outside corners that is one piece and which therefore does not require the manufacture of a plurality of segments of molding and which does not require the formation of a compound corner using the plurality of segments.
A still further advantage of the present invention is to provide a novel miterless molding system for rounded inside and outside corners that is easily and quickly installed with a lower skill level than would be required for installation of a compound corner.
