DETAILED DESCRIPTION

(10) The following discussion provides many example embodiments of the inventive subject matter. Although each embodiment represents a single combination of inventive elements, the inventive subject matter is considered to include all possible combinations of the disclosed elements. Thus if one embodiment comprises elements A, B, and C, and a second embodiment comprises elements B and D, then the inventive subject matter is also considered to include other remaining combinations of A, B, C, or D, even if not explicitly disclosed.

(11) For illustrative purposes, the present invention will be described and illustrated as it relates to rolls of toilet paper. However, this should not be interpreted as a limitation of the invention. Those of skill in the art will appreciate that the present inventive subject matter has uses in any application involving rolls of a wound product, regardless of whether the product is a paper absorbent. Examples of other materials may include, but are not limited to; non-woven fabrics, films, textiles, screens, meshes, and composite or laminates containing one or more of the above. Examples of products include rolls of stamps, rolls of plastic wrap, rolls of aluminum foil, and rolls of tickets. Products of particular interest to the present application include paper towels, wet wipes, dry wipes, sheets, coverings, and the like.

(12) FIGS. 1-3 show front, top, and side views, respectively, of an adapter assembly 1 holding a roll of toilet paper 19. Adapter assembly 1 includes a frame 26 and a reduced-core spindle 2. Frame 26 is defined by: (i) right and left vertical walls 15 and 16 respectively (i.e., tabs); (ii) right and left side arms 10 and 11, respectively; and (iii) upper and lower cross members 13 and 14, respectively. Upper and lower cross members 13 and 14 are coupled with right and left vertical walls 15 and 16, creating a specific spaced-apart distance between right and left side arms 10 and 11. Right and left arms 10 and 11 have right and left spindle receivers 6 and 7 for holding spindle 2. Although FIGS. 1-3 show upper cross member 13, lower cross member 14, right side vertical wall 15 and left side vertical wall 16 as individual parts, one skilled in the art will appreciate that these members could also be fabricated as one integral part, or any combination of subparts.

(13) FIGS. 1-3 also show a dust cover 12, which is attached to upper cross member 13 by hinges 18. Dust cover 12 protects and covers roll of toilet paper 19 from dust and debris. In FIG. 1, adapter position stops 17 are shown as protrusions extending from right and left vertical walls 15 and 16. Stops 17 provide a means for properly aligning and installing adapter assembly 1 in a cavity of a recessed dispenser.

(14) FIG. 4 shows a front view of adapter assembly 1 with roll of toilet paper 19 and spindle 2 removed. With spindle 2 removed, one can more clearly observe right and left spindle receivers 6 and 7, which are attached to the ends of right and left arms 10 and 11, respectively. Receivers 6 and 7 have receiver cups 8 and 9, respectively, for holding spindle 2.

(15) FIG. 5 shows a front view of adapter assembly 1 with spindle 2 loaded between cups 8 and 9. Roll of toilet paper 19 has been removed. Spindle 2 comprises a housing 3 that slidably couples with a retractable arm 4 and arm end 5. Spindle 2 is similar to the spindle disclosed in co-pending U.S. patent application Ser. No. 13/288,257, filed on Nov. 3, 2011 to Phelps and titled Spindle for Roll Paper Products, which is incorporated herein by reference. Spindle 2 can expand and contract, thus allowing the ends of spindle 2 to expand into cups 8 and 9. Those of skill in the art will appreciate that cups 8 and 9 could comprise any removable coupling suitable for holding spindle 2. For example, cups 8 and 9 could alternatively comprise two protrusions that fit into cups or recesses at the ends of spindle 2. Cups 8 and 9 could also comprise female connectors that releasably engage male connectors on the ends of spindle 2. The present inventive subject matter is not intended to be limited by the type of removable coupling used between spindle 2 and adapter assembly 1.

(16) Spindle 2 is preferably a reduced-core spindle, meaning the maximum outer diameter of the spindle is smaller than the spindle originally intended for the recessed dispenser. In this manner, adapter assembly 1 and spindle 2 provide a means for retrofitting recessed dispensers to allow for use with larger rolls of toilet paper that have reduced cores.

(17) FIG. 6 shows a top view of the recessed adapter assembly 1 shown with dust cover 12 attached to upper cross member 13 by hinges 18. In addition, FIG. 6 shows upper cross member 13 attached to right vertical wall 15 and left vertical wall 16.

(18) FIG. 7 shows a side view of adapter assembly 1, showing a double sided tape fastener 25 attached to right vertical wall 15. Fastener 25 provides a means for attaching vertical wall 15 to a sidewall of a cavity of a recessed dispenser. Those of skill in the art will appreciate that numerous fastener types could be used consistently with the inventive subject matter disclosed herein. Any fastener suitable for supporting adapter assembly 1 to a cavity is contemplated. In alternative embodiments, the fastener could comprise screws and screw-holes. The fastener could also comprise expanding protrusions configured to engage recesses in the sidewalls of the cavity.

(19) FIG. 8 shows a front view of the dual roll recessed dispenser 17, which is designed to mount to the partition separating two bathroom stalls. Each side of dual roll recessed dispenser 17 is usable by each stall user. Dispenser 17 includes a cavity 18 and a cavity 19 configured to accommodate a standard-sized roll of toilet paper having a standard-size core diameter. Both cavity 18 and 19 utilize a standard spindle 20. Spindle 20 is different from spindle 2 in that spindle 20 is configured to hold a standard-sized core diameter roll of toilet paper, not a reduced-core roll of toilet paper. As such, spindle 20 can utilize snap-fit connections, which are compatible with the larger dimensions of spindle 20. Adapter assembly 1 is configured to fit within cavities 18 and 19. With both standard spindles 20 removed, adapter assembly 1 can be inserted into cavities 18 and 19 until stops 17 contact front outer surface 21. Fasteners 25 can then be used to secure adapter assembly 1 to the sidewalls of cavities 18 and 19.

(20) FIG. 9 shows a side view of the dual roll recessed dispenser 17 showing front surface 21, upper cavity 18, and lower cavity 19.

(21) Unless the context dictates the contrary, all ranges set forth herein should be interpreted as being inclusive of their endpoints, and open-ended ranges should be interpreted to include commercially practical values. Similarly, all lists of values should be considered as inclusive of intermediate values unless the context indicates the contrary.

(22) As used herein, and unless the context dictates otherwise, the term coupled to is intended to include both direct coupling (in which two elements that are coupled to each other contact each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms coupled to and coupled with are used synonymously.

(23) It should be apparent to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the scope of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms comprises and comprising should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification claims refers to at least one of something selected from the group consisting of A, B, C . . . and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.
