Likewise, the disclosure is not limited to various embodiments given in this specification.

(19) Without intent to further limit the scope of the disclosure, examples of instruments, apparatus, methods and their related results according to the embodiments of the present disclosure are given below. Note that titles or subtitles may be used in the examples for convenience of a reader, which in no way should limit the scope of the disclosure. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. In the case of conflict, the present document, including definitions, will control.

(20) It will be appreciated that terms such as “front,” “back,” “top,” “bottom,” “side,” “short,” “long,” “up,” “down,” “aft,” “forward,” “inboard,” “outboard” and “below” used herein are merely for ease of description and refer to the orientation of the components as shown in the figures. It should be understood that any orientation of the components described herein is within the scope of the present invention.

(21) Referring now to the drawings, wherein the showings are for purposes of illustrating the present invention and not for purposes of limiting the same, FIGS. 1-12 show a method for creating or making an article of manufacture that is comprised of a plurality of layers. In an exemplary embodiment, the article of manufacture is a countertop assembly that includes a sink, countertop and backsplash that can be used in aircraft lavatories and/or galleys. However, this is not a limitation on the present invention and the method described herein can be used to make other articles of manufacture. For ease of description, and as shown in the figures, the article of manufacture described herein is a countertop assembly 10 (see FIG. 9) that includes a countertop 12, backsplash 14 and sink 16.

(22) FIGS. 1-4 show at least some of the steps in creating the countertop 12 and backsplash 14, FIGS. 5-7 show at least some of the steps in creating the sink 16 and FIGS. 10-12 show at least some of the steps in creating another sink 16. As shown in FIG. 1-2, each of the backsplash 14 and countertop 12 are comprised of a plurality of layers 18 (FIG. 2) that are machined, cut, or otherwise divided from a sheet of material 20 (FIG. 1). In another embodiment, the various layers can be machined from more than one sheet. In another embodiment, the various layers can created from a mold. Each layer 18 includes one or more alignment openings 22 that are defined in an alignment member 24 that extends outwardly in a lateral or longitudinal direction from the layer. As shown in FIG. 2, the layers can be different shapes. For example, there can be layers 18 that are strip members 18a and layers 18 that are panel members 18b.

(23) Next, an adhesive, glue, bonding agent or other substance that can secure the layers 18 together is disposed on the appropriate surfaces of adjacent layers 18 and the layers are then stacked on one another. The corresponding alignment openings 22 and alignment members 24 are then aligned with one another and alignment rods 26 are inserted through the alignment openings 22 to keep the layers 18 in proper alignment or orientation. It will be appreciated that the order of the alignment steps can be done in a different order. For example, the alignment rods 26 can be inserted through the alignment openings 22 in a first layer 18 and then the other layers 18 can be stacked on top by placing the alignment rods into the alignment openings in a second layer 18, then placing the second layer on top of the first layer 18 and then repeating these steps for the remaining layers.

(24) After all the layers 18 are stacked, the adhesive is allowed to dry such that they are bonded together, thereby creating a stack assembly 28, as shown in FIG. 3. The alignment rods 26 are removed from the alignment openings 22. Next, the stack assembly is machined and polished to smooth out the layers and edges. In other words, some of the outer surfaces or the layers are machined down to create a smooth surface (compare the outer surfaces in FIGS. 3 and 4). During the machining process, in a preferred embodiment, some or all of the alignment openings 22 and alignment members 24 are removed. FIG. 7 shows the sink 16 with some alignment members 24 and alignment openings 22 remaining (for alignment with the countertop, as described below) and FIG. 12 shows the sink 16 with all of the alignment members and alignment openings 22 removed. The machined and polished stack of layers are referred to herein as a finished assembly 30. A stack of alignment members that have been polished are referred to herein as an alignment column. For example, see FIG. 8 and the alignment columns 50 on the inside thereof.

(25) It will be appreciated by those of ordinary skill in the art, that during the machining process, square portions or edges can be removed to provide a smooth surface. For example, see square portion 32 in FIG. 6 that has been removed in FIG. 7 to create the smooth sink bowl. As shown in FIGS. 10-12, in other instances, a plurality of layers that are stacked in series can include increasing or decreasing geometries of dimensions with a series of squared portions 32 (see FIG. 11). When these series of squared portions 32 are machined they provide an inclined or curved surface (see FIG. 12). As shown in the drawings, the different layers 18 can include be a series that include openings therein to provide the upwardly extending walls of the sink and solid layers that become the bottom of the sink.

(26) FIGS. 8 and 9 show another aspect of the present invention where more than one finished assembly 30 can be secured to one another to provide the final article of manufacture. In the exemplary embodiment shown in the drawings, the finished countertop assembly 10 includes the countertop 12 with the sink 16 secured thereto. In a preferred embodiment, the countertop 12 includes a sink rim 48 on a bottom surface thereof. The sink rim 48 surrounds a sink opening 46. The sink rim 48 can be a separate layer 18 that is part of the stacking process or the sink rim 48 can be machined into the countertop layer 42. The sink rim 48 includes at least one and preferably a plurality of alignment members 24 and alignment openings 22 that correspond to the remaining alignment members 24 and alignment openings 22 in the finished assembly 30 of the sink 16. In another embodiment, the rim can be omitted and the alignment openings 22 can be defined directly in the countertop layer 42. Alignment rods 26 are placed in the alignment openings 22 of the sink 16 and the alignment openings of the sink rim 48 and the two components are bonded together using adhesive.

(27) As discussed above, in a preferred embodiment, some of the alignment members and openings are removed during the machining process and some are left on the sink so that they can be aligned with alignment members and openings on the countertop. In other words, there are originally a first number of alignment members on the sink or first stack assembly and, when the first finished assembly is created there are a second number of alignment members, where the second number is less than the first number. The second number of alignment members (or alignment columns) matches the number of corresponding alignment members or openings on the second finished assembly (e.g., see the three alignment members and openings in FIG. 8).

(28) With reference to the specific embodiment shown in FIGS. 2-4, the countertop 12 layers 18 include a plurality of front bullnose layers 32 and the backsplash 14 include a plurality of top flange layers 34. The assembly also includes a radius body 36, for where the countertop 12 and backsplash meet 14, a waste flap layer 38, the countertop layer 42 and a backsplash layer 44. The waste flap layer 38 is secured adjacent a waste opening 40 defined in the countertop layer 42.

(29) After the finished assemblies are created the components can be coated, sanded or otherwise finished as desired. It will be appreciated that any material that is capable of being machined is within the scope of the present invention. For example, the layers can be made of Corian® or similar substances.
