DETAILED DESCRIPTION OF THE INVENTION

[0016] Novel features which are characteristic of the invention, as to organization and method of operation, together with further objects and advantages thereof will be better understood from the following description considered in connection with the accompanying drawings, in which preferred embodiments of the invention are illustrated by way of example. It is to be expressly understood, however, that the drawings are for illustration description only and are not intended as definitions of the limits of the invention. The various features of novelty which characterize the invention are recited with particularity in the claims

[0017] There has been broadly outlined more important features of the invention in the summary above and in order that the detailed description which follows may be better understood, and in order that the present contribution to the art may be appreciated. There are, of course, additional features of the invention that will be described hereinafter and which will form additional subject matter of the claims appended hereto. Those skilled in the art will appreciate that the conception upon which this disclosure is based readily may be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important therefore, that claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.

[0018] Certain terminology and the derivations thereof may be used in the following description for convenience and reference only, and will not be limiting. For example, words such as “upward,” “downward,” “left,” and “right” refer to directions in the drawings to which reference is made unless otherwise stated. Similar words such as “inward” and “outward” refer to directions toward and away from, respectively, the geometric center of a device or area and designated parts thereof. Reference in the singular tense include the plural and vice versa, unless otherwise noted.

[0019] Turning to FIG. 1, cardboard scratcher elements 11 and 12 are shown being nested within one another to reduce their overall volume during shipment and storage. Each cardboard element is self-supporting having no backing or substructure and each has exposed surfaces, namely, surfaces 13 and 14 having open flutes 8 and 9 interposed between planar cardboard sheets 7A/7B and 6A/6B respectively (FIG. 4). In preparing scratcher 10 for use, scratcher element 12 is moved from its nested position (FIG. 1) to its in-use position (FIG. 2) by removing scratcher element 12 from beneath scratcher element 11 and rotating it 180° as shown in FIG. 2 It must be emphasized at this time that scratcher 10 composed of subparts 11 and 12 is illustrative of a kit of parts composed of self-supporting cardboard bodies which can be nested for shipment and storage and rearranged for use and that the present invention is not to be limited to this illustrated structure but applies to any kit, the scope of which is defined by the appended claims

[0020] Once scratcher element 12 has been moved from beneath scratcher element 11 as shown in FIG. 2, connectors such as connectors 35 and 35A can be applied to maintain the FIG. 2 orientation. In doing so, it is noted that both surfaces 13 and 14 provide open fluted faces which is an ideal scratching medium for a cat

[0021] In returning again to FIG. 2, and in reference to FIG. 3A, connector elements 35 and 35A are provided with shaft 33 of a length greater than first width 15 of scratcher element 11 and less than the combination of first and second widths 15 and 16 Further, connectors 35 and 35A are provided with helical threads 32A and 32B along shaft 33 noting that helical threads 32A extend from shaft 33 to a lesser extent proximate second end 37 than threads 32B proximate first and 36 thereof. This facilitates application of connectors 35 and 35A as shown.

[0022] There are a number of suitable variations of connectors for use herein, those depicted in FIGS. 3A-3C being illustrative of many of which can be employed in practicing the present invention. For example, connector 35 are provided with helical male protrusion 34 sized to receive female end 23 of wand 21 which, in turn, supports attractant 22 at end 24 Protrusion 34 extends from head 31, the latter being sized and configured to enable a pet owner to apply the connector as shown in FIG. 2 without resorting to any tools. Thus, connector 35 not only maintain the orientation of scratching elements 11 and 12 for use as a scratcher but also can support a wand and an attractant making the present scratcher more interesting to the pet. As wand 21 is removable from these connectors, wands of various sizes and diverse attractants can be releasably applied to the scratcher to increase its appeal and reduce the potential for boredom

[0023] As further non-limiting examples of suitable connectors, reference is made to FIGS. 3B and 3C As was the case with the connector of FIG. 3A, connectors 45 and 55 have shafts 43 and 53 of suitable length and are provided with helical threads 42A/42B and 52A/52B, respectively. In the example of FIG. 3B head 41 comprises indent 44 for receiving a screwdriver or coin to facilitate turning the connector within the flutes of scratcher elements 11 and 12. As for the connector illustrated in FIG. 3C, head region 51 is arbitrarily depicted as the head of a cat. This substantially planar extension is sized to enable a user to grasp it and to turn the connector within the receiving flutes Furthermore, head region 51 includes opening 48 to enable an umbilical (not shown) to be tied to head region 51 for support of a suitable attractant, such as attractant 22 of FIG. 2

[0024] In turning to FIG. 4, a cross-section taken along 4-4 of FIG. 2 is shown together with connector 35. Shaft 33 is inserted within one of flutes 8 extending into exposed surface 13. As connector 35 is rotated, helical threads 32A begin to deform flutes 8 and cause shaft 33 to be drawn within the body of scratching element 11. As connector 35 continues to penetrate scratching element 11, helical threads 32B further deform flutes 8 as well as adjacent cardboard sheets 62 and 63 as shown. In fact, in most instances, helical threads 32B are sufficient to break cardboard sheets 62 and 63 on either side of receiving flute 8. As connector 35 continues to progress, it confronts surface 14 of scratching element 12 penetrating one of flutes 9 causing a similar deformation of cardboard sheets 64 and 65

[0025] The above disclosure is sufficient to enable one of ordinary skill in the art to practice the invention, and provides the best mode of practicing the invention presently contemplated by the inventor While there is provided herein a full and complete disclosure of the preferred embodiments of the invention, it is not desired to limit the invention to the exact construction, dimensions, relationships, or operations as described Various modifications, alternative constructions, changes and equivalents will readily occur to those skilled in the art and may be employed as suitable without departing from the true spirit and scope of the invention. Such changes might involve alternative materials, components, structural arrangements, sizes, shapes, forms, functions, operational features or the like. Therefore, the above description and illustration should not be considered as limiting the scope of the invention, which is defined by the appended claims.
