Brabant, U.S. Pat. No. 5,651,224 describes an architectural molding assembly comprising of straight molding pieces having a decorative outer surface and a channel in the rear surface thereof. A wall attaching plate is slidingly secured in the channel and has a slot or an aperture therein to engage with a fastener which is secured to a wall. The fastener may be in the form of a screw or a clamp having a projecting finger. When the attaching plates are engaged by the fasteners they are urged against the wall and maintained there under tension. No nail is inserted in the molding and molding connecting pieces and accordingly the assembly can be easily dismantled and remounted when desired.
Wu, U.S. Pat. No. 5,694,726 describes a plastic plate assembly used in fitting including a flat and linear retainer plate and a casing having curved surfaces. The retainer plate has an L-shaped retaining strip bending inwardly from either lateral side thereof. Correspondingly, the casing has an L-shaped retaining strip bending outwardly from either lateral side thereof for fitting onto the L-shaped retaining strip. The casing further has one of the lateral sides extending to form a soft extension strip at an end portion thereof. The retainer plate is mounted on the wall first and the casing is secured thereto by means of its L-shaped retaining strips fitting into the L-shaped retaining strips of the retainer plate, with the soft extension strip lying close against the wall to conceal any gaps between the casing and the wall.
Brooks, U.S. Pat. No. 5,823,655 describes a decorative lighting trim system comprising an assemblage of architectural moldings having a viewable surface which is structured to simulate an architectural trim or molding. The architectural molding is configured to retain lights, and to retain and conceal interconnecting electrical wiring to electrify the lights, in a manner which permits the attachment of the architectural moldings to a building surface. Because the architectural moldings are constructed to appear like conventional trims or moldings, the lighting system is virtually inconspicuous when attached to a house, building or other architectural structure, such as a fence or garage. The architectural moldings are in modular sections having varying selected lengths which allow the user to select the appropriate number and length of modular sections to extend along a given building surface, such as an eave, gable or window. The modular architectural molding assemblage is designed to be affixed relatively permanently to a building to eliminate the need for yearly seasonal hanging of lighting trim.
Hahn, U.S. Pat. No. 6,228,507 describes a prefabricated crown molding strip designed to facilitate one-person installation and composed of plaster that is reinforced by two layers of fiber reinforcement, one of bulk fiberglass intermixed throughout the outer portion of the strip and the ornamentation thereon and a second of a sheet of fiberglass netting generally centrally located as a spine in the strip and substantially coextensive therewith. Two side surfaces of the strip are disposed generally in perpendicular planes for engagement with a wall and a ceiling, and have patterns of longitudinally extending ribs and grooves of predetermined depths for facilitating adhesive mounting of the strip, and also facilitating selective removal of plaster to accommodate irregularities on supporting surfaces. Pre-formed nail holes are molded in preselected nailing locations. Also the method of making crown molding strips in steps providing the above characteristics, in a sequence of pours of plaster in fluid state, the addition of the reinforcing fiber, and formation of the patterns of ribs and grooves.
Ancel, U.S. Pat. No. 6,309,036 describes an elongate back splash molding including a horizontal leg, adapted to be received in an upwardly opening notch provided in a counter top, and a vertical leg, integral with the horizontal leg, adapted to be received by a downwardly opening notch provided in a back splash which is mounted on the counter top rearwardly adjacent the slot. The horizontal leg includes a curvilinear top surface and a front surface joined to the curvilinear surface at via an edge which lies flush with the upper surface of the counter top. The vertical leg includes a front curvilinear surface having a lower end which makes a smooth transition with the curvilinear top surface. The vertical leg also includes an elongate top end face which is downwardly forwardly inclined and is joined to the top front surface along an edge which is flush with the front face of the back splash and an upper end disposed flush with the front face of the back splash. The confronting surfaces of the counter top, back splash and back splash molding, which are formed of non-laminated, non-foamed, non-coated, plastic solid surfacing material, are adhesively joined to provide a water impervious, virtually imperceptible joint.
Reed, U.S. Pat. No. 6,405,503 describes a corner trim for use with vinyl or aluminum siding, which provide an appearance similar to that provided by the use of cast concrete corner stones at a fraction of the cost. The new corner trim is essentially a shell formed to have the appearance of a corner stone. Like the cast concrete stones it emulates, it is designed to fit over the corner of a structure. It may be manufactured from polymeric vinyl material via either injection molding or sheet forming process, or it may be formed by stamping sheet aluminum sheet. If aluminum is used, some welding may be required at the corners of the trim. A first embodiment of the corner trim incorporates a laminar, perimetric rim at the edges of the shell. When mounted on the building corner, the rim is perpendicular to the walls. A separate perimetric mounting strip is stapled to the wall sheathing on both sides of the building corner. The corner trim is then pressed into place on the corner, with the edges of the corner trim mating with the mounting strip. A plurality of barbs may be employed to secure the rim to the mounting strip. Alternatively, the corner trim may be adhesively bonded to the mounting strip. A preferred embodiment of the corner trim incorporates a perimetric groove having a width slightly greater than the thickness of the siding, and in which the ends and edges of the abutting siding pieces terminate to provide a finished look. A second embodiment of the corner trim does not employ a separate mounting, but rather incorporates a perimetric mounting strip that may be stapled directly to the wall sheathing.
Weldy, RE34,547 describes a wall edging system for strengthening the wall intersections of buildings replacing the conventional metal corner bead used on drywall joints. The principal element of the system is an extruded plastic strip having a thickened, arcuate central area and two outwardly extending flanges which are othogonally oriented to one another, so that the thickened central portion runs along the seam between the orthogonally intersecting walls, and the flanges extend outwardly along the thickened central portion to be nailed into the drywall to secure the strip to the edge. Means is provided for providing a purchase for the mud that is applied over the flanges, and in addition to the strip there are other pieces defining two-leg and three-leg inside and outside corners, these pieces having tongues extending from each of the legs which slip beneath the central, thickened portions of the adjacent linear strips to provide a secure meeting at the corner.
Boomer, U.S. 2001/0045076 A1, describes a building component that is in the form of an elongate prefabricated cornice to be used in lengths around the top of a wall or walls or a room. The cornice has a mounting part and a facing part. The mounting part has a cross-section with two legs at an angle to each other. The outer edge of each leg terminates in a reflexive bend with the outer portion of the bends inwardly directed. The facing part is a strap of material capable of being snap-fitted into or slid along the mounting part with the inside of each bend serving as a seat to receive a longitudinal edge of the facing part. A corner-piece is provided to join two adjacent lengths of cornice at a corner, the corner-piece being in two parts having a wall-mountable angle bracket and a correspondingly angled cornice part to be secured thereto.
Stovax Limited, GB 2274860 describes a cornice that is formed of a series of similar ceramic elements arranged end-to-end. Each ceramic element has parallel flat ends, a concave decorative front face and a rear face. The elements are of substantially uniform transverse cross section and are symmetrical about a central longitudinal axis. The rear face is bounded by a pair of flat, longitudinally extending marginal bonding surfaces which lie on mutually perpendicular planes. Each of the bonding surfaces joins a mutually perpendicular flat abutment face respectively which in turn join the front face. The length of each cornice element may equal that of a wall tile.
The prior art teaches the use of artistic moldings for room appearance enhancement and of the use of corner pieces for adapting generally long linear tiles to a corner of a room. The prior art does not teach a linear tile having built-in corner turning portions at both ends or the use of inserts in a corner portion to adapt the moldings to a custom appearance or a thicker corner portion to adapt abutting ends in an improved manner. The present invention fulfills these needs and provides further related advantages as described in the following summary.

SUMMARY OF THE INVENTION

The present invention teaches certain benefits in construction and use which give rise to the objectives described below.
Because wall surfaces in buildings tend to be bowed or cupped (non-planar) and have rough surfaces or rough spots, and because abutting walls tend to be misaligned at their joints, abutting tiles mounted thereon generally do not form perfectly matched butt joint seams. Three types of seam discrepancies exist. First, the top surfaces of the abutting tiles may not be coplanar so that a step discontinuity may be visible; second, the front decorative surfaces may not be at right angles at a wall abutment, so that the joint seam of the tiles may not be closed at the front face, or if closed at the front face a gap will exist at the rear surface and closure of the seam at the front surface will vary in the seam along a vertical direction due to wall surface non-planarity. The third seam problem occurs when the abutting wall surfaces are not mutually vertical or are not mutually aligned when off-vertical so that the seam is only in true alignment at one point and unaligned at all other points. These three alignment difficulties are grossly exaggerated in corners when a butt joint uses a pair of tiles where each is mounted to one of the walls. To complicate matters further, the molding process for cast or molded (plaster, plastic, etc.) parts does not result in identical sizes or thicknesses of the several portions of the tiles, because of mold variations and also variations in the molding materials component mix or ratios, amount of shrinkage and other variables in production. The present invention reduces the number of seams required at a corner from two, using the prior art method of inserting a corner piece, to one, a reduction of 50%, and this results in a reduction of the same order of magnitude in the applied labor necessary to achieve a perfect integration of the several parts. Of course, this results in significant savings to the end user. Additionally, by forming a corner turning portion of the invention with a step in surface continuity where the abutment exists, matching seams at abutments becomes very easy to accomplish and post installation labor is significantly reduced.
The instant solution provides a crown molding tile system where a first tile provides a laterally extensive linear portion, similar to common linear tiles, with a rear wall-engaging surface configured for surface-to-surface contact with a first generally flat wall. The linear portion terminates at both of its ends with an integral corner-turning portion which is relatively small as compared to the length of the linear portion. Thus only one tile need be manufactured for all applications with one of the corner turning portions cut off depending on which end is to be used to turn a corner. The rear wall-engaging surface of the corner-turning portion is oriented for contact with a second wall usually set at an approximately 90 degree angle or larger to the first wall. The corner-turning portion terminates laterally with a right-cut, non-mitered first edge, laying in a plane generally perpendicular to the second wall wherein the first edge abuts a second linear tile with an edge conforming to the first edge of the corner-turning portion, for forming a uniformly tight butt-seam. The corner-turning portion is thicker than the linear tiles or portions, so that wall misalignment problems are not visual in most cases. This is because it is easy to see a misalignment between abutting tiles which are meant to form a continuous smooth surface, but instead exhibit a break line, but it is difficult to see a misalignment when it is masked by a natural surface break or level change.
A primary objective of the present invention is to provide an apparatus and method of use of such apparatus that provides advantages not taught by the prior art.
Another objective is to provide such an invention capable of being more easily fitted to non-planar or misaligned wall surfaces while rendering an adequate appearance without excessive post mounting work to assure proper fitting of tile abutments.
A further objective is to provide such an invention capable of being fitted to inside and outside corners with improved butt joint appearance.
A still further objective is to provide such an invention capable of providing a continuous crown molding installation with fewer butt joints, while accommodating typical imperfectly aligned wall surfaces.
Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.

DETAILED DESCRIPTION OF THE INVENTION

The above described drawing figures illustrate the invention in at least one of its preferred embodiments, which is further defined in detail in the following description. Those having ordinary skill in the art may be able to make alterations and modifications in the present invention without departing from its spirit and scope. Therefore, it must be understood that the illustrated embodiments have been set forth only for the purposes of example and that they should not be taken as limiting the invention as defined in the following.
The present invention is a crown molding apparatus made up of individual tiles which are abutted to form a continuous molding strip, and a system made up of the assembly of the tiles. Now referring to the above defined figures, the separate pieces shown are referred to herein as tiles of the system. The tiles are made of molded plaster or plastic in a manner that is well known in the art, and are formed in shapes represented as shown in the figures, but may be formed in alternate shapes as well. A front decorative surface 20 (FIG. 3) faces outwardly from a mounting wall surface 5 or 5′ upon which the tiles are mounted, typically by screws or other hardware and/or bonding agents. In opposition to the front surface 20, the tiles have a rear wall-engaging surface 30 abutting one or both of the wall surfaces 5, 5′.
The tile system is mounted onto the wall surfaces 5, 5′ and, in this invention, in particular at corners where the wall surfaces 5 and 5′ abut. In this description we define the “wall abutment vicinity” as those portions of the wall surfaces 5 and 5′ that extend away from the corner where the surfaces 5 and 5′ actually meet by from about 5 to 10 inches, and of course includes the actual meeting of the surfaces at the corner. A tile that covers such a corner shall be referred to herein as a “corner turning portion” and labeled by the numeral 70 in the figures no matter if for an inside corner as in FIG. 1, or an outside corner as in FIG. 2. Tiles that abut these corner turning portions 70 shall be referred to as “leg portions” 71, no matter if the leg portion 71 is integral with the corner turning portion 70, or if it is a separate part. FIG. 3 shows both of these possibilities.
Now, referring to FIG. 3, a first corner turning portion 70 has a lateral extent, horizontally, for covering the wall abutment vicinity of the wall surfaces 5, 5′. A horizontally oriented, linearly extensive, leg portion 71 (to the left) is integral with the first corner turning portion 70 and an interface 90 between the leg portion 71 and the corner turning portion 70 is defined by a thickness differential (FIG. 4), one being thicker then the other as shown in FIGS. 5A, 5B, 6A and 6B. The advantage of having this thickness differential will be described below. The tiles abut at surface 26.
Preferably, the corner-turning portion 70 provides a frontal recess 72 as best shown in FIGS. 1 and 5A, and further comprises a separable frontal decorative insert 23 which is adapted for fitting within the frontal recess to provide a selectable decorative surface 24.
As shown in FIG. 3, a second corner turning portion 70 (at far left) may be formed integrally with the leg portion 71 and spaced apart from the first corner turning portion 70 in opposing juxtaposition. The second corner turning portion 70 also is formed having a horizontal, lateral extent, for covering the wall abutment vicinity. Again, an interface between the leg portion 71 and the second corner turning portion 70 is defined by the thickness differential 90.
In FIG. 3 this is shown by thicknesses t and t′ although, alternately, t′ may be made thicker than t. FIGS. 5B and 6B show this case.
As shown in FIG. 3 the corner turning portion 70 may be integral with the leg portion 71 (shown at left in FIG. 3), or the leg portion 71 may be a separate part (shown at right in FIG. 3). As stated, in either case, the leg portions 71 are of a different thickness with respect to the corner turning portions 70. This thickness differential 90 provides an advantage to the installer since it is easy to disguise non-uniformities in the mounting surfaces 5 and 5′ by using a thickness differential. It is difficult to disguise misalignment where two tiles abut when they must match perfectly along a common joint line.
The enablements described in detail above are considered novel over the prior art of record and are considered critical to the operation of the instant invention and to the achievement of the above described objectives. The words used in this specification to describe the invention and its various embodiments are to be understood not only in the sense of their commonly defined meanings, but to include by special definition in this specification: structure, material or acts beyond the scope of the commonly defined meanings. Thus if an element can be understood in the context of this specification as including more than one meaning, then its use must be understood as being generic to all possible meanings supported by the specification and by the word or words describing the element.
The definitions of the words or elements of this described invention and its various embodiments are, therefore, defined in this specification to include not only the combination of elements which are literally set forth, but all equivalent structure, material or acts for performing substantially the same function in substantially the same way to obtain substantially the same result. In this sense it is therefore contemplated that an equivalent substitution of two or more elements may be made for any one of the elements in the invention and its various embodiments or that a single element may be substituted for two or more elements in a claim.
Changes from the claimed subject matter as viewed by a person with ordinary skill in the art, now known or later devised, are expressly contemplated as being equivalents within the scope of the invention and its various embodiments. Therefore, obvious substitutions now or later known to one with ordinary skill in the art are defined to be within the scope of the defined elements. The invention and its various embodiments are thus to be understood to include what is specifically illustrated and described above, what is conceptually equivalent, what can be obviously substituted, and also what essentially incorporates the essential idea of the invention.
While the invention has been described with reference to at least one preferred embodiment, it is to be clearly understood by those skilled in the art that the invention is not limited thereto. Rather, the scope of the invention is to be interpreted only in conjunction with the appended claims and it is made clear, here, that the inventor(s) believe that the claimed subject matter is the invention.
