DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENT(S)

(12) Various embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In the following description, specific details such as detailed configuration and components are merely provided to assist the overall understanding of these embodiments of the present invention. Therefore, it should be apparent to those skilled in the art that various changes and modifications of the embodiments described herein may be made without departing from the scope and spirit of the present invention. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

(13) Referring now to FIG. 1, an exemplary spool protector 10 is shown positioned on a wire reel 12. In this particular embodiment, the wire reel 12 includes a spool drum 15 positioned between a first flange 14 on a right side thereof, and a second flange 16 on a left side thereof. Each flange 14, 16 may include a number of apertures 18. The apertures 18 may reduce the overall weight of the wire reel 12, permit wire and/or other material to be positioned therethrough, may increase rolling capacity of the wire reel 12, some combination thereof, or the like. The flanges 14, 16 and drum 15 of the wire reel 12 may each comprise plastic, although such is not necessarily required. Here, the exemplary spool protector 10 is positioned over a perimeter of the second flange 16, and the first flange 14 does not include an exemplary spool protector. It will be apparent to one of ordinary skill in the art that wire reels shown and described herein are merely illustrative, and are in no way exhaustive of the scope of the present invention. Any number of different spools of any number of different shapes and/or sizes may be employed without necessarily departing from the scope of the present invention.

(14) Without an exemplary spool protector, the first flange 14 may be susceptible to cracking, fracturing, breaking, bending, snapping, some combination thereof, or the like (e.g., resulting from force in material unwound from the wire reel acting on the first flange 14). A portion of the first flange 14 between an outer perimeter of the first flange 14 and an aperture 18 may be particularly susceptible to damage due to the thinness and lack of reinforcing material for said portion. Thus, it may be advantageous to provide reinforcing material to said portion by way of an exemplary elastic spool protector configured to substantially cover said portion. Although FIG. 1 illustrates one flange having an exemplary elastic spool protector linked thereto, in other exemplary embodiments, each flange of a wire reel may be linked to a respective exemplary elastic spool protector to protect and reinforce all flanges (e.g., protection from impact damage).

(15) Exemplary elastomeric material of an elastic spool protector 10 may comprise any number of different flexible materials collectively providing a high friction coefficient (e.g., for immobilization of the protector 10 on the flange 16) without limiting the ability of the elastic spool protector 10 to be readily removed from the flange 16. By way of example and not limitation, rubber, silicone, latex, soft plastic, other flexible 3D-printable filaments, some combination thereof, or the like may define an exemplary elastic spool protector 10. Exemplary elastomeric material may be affordable, and manufacturing of an exemplary elastic spool protector may be streamlined according to 3D-printing, other additive manufacturing techniques, injection molding, some combination thereof, or the like.

(16) The elastic spool protector 10 may be stretched over a perimeter of the flange 16 and may constrict around the perimeter to cover an outer portion of the flange 16. The elastic spool protector 10 may reinforce the wire reel 12, preventing cracks and or breaks (e.g., resulting from force applied by a wire) from forming in the flange 16. Alternatively, or additionally, the elastic spool protector 10 may permit continued use of an already damaged flange (not shown) by covering cracked and/or broken portions thereof, and providing reinforcement thereto. Thus, an exemplary elastic spool protector (e.g., 10) may reduce waste resulting from scrapped wire reels. It will be apparent to one of ordinary skill in the art that an exemplary elastic spool protector may be positioned on and/or removed from any number of different wire reels, other spools, other flange-comprising apparatuses, and the like. By way of example and not limitation, when continued use of an exemplary elastic spool protector on a first spool is no longer desired, the elastic spool protector may be removed from the first spool, and may thereafter be positioned on a second spool.

(17) Referring to FIGS. 2-3 and 7-8, various views of an exemplary elastic spool protector 10 independent of a flange are shown. A curved rim portion of the spool protector 10 may form an outer extent of a disk-shaped member. The rim portion may include a flange grip portion (lip portion 28) and a perimeter portion 22, but such is not necessarily required. The lip portion 28 may extend from the perimeter portion 22 for a distance over a rear portion 26 of the disk-shaped member. Specifically, the lip portion 28 may extend from the perimeter portion 22 to a lip edge 30. In the FIG. 3 embodiment, the lip portion 28 extends approximately 0.5 inches from the perimeter portion 22 to the lip edge 30, but such is not necessarily required in other embodiments. Certain other exemplary embodiments may include a lip portion extending anywhere between 0.2 inches to 2 inches over the rear portion of the disk-shaped member, but the aforementioned range is also not necessarily required. Here, the lip portion 28, similar to the perimeter portion 22, is substantially curved. It will be apparent to one of ordinary skill in the art that the thickness, shape, rigidity, size, some combination thereof, or the like of an exemplary elastic wire reel protector and components thereof (e.g., lip portion 28) may be varied without necessarily departing from the scope of the present invention.

(18) An amount of space (referred to herein as a receptacle) may be present between the lip portion 28 and the rear portion 26 of the elastic spool protector 10. The receptacle may be configured to receive an outer portion of a flange (not shown). The receptacle width may be varied to accommodate any number of different flange widths. The elastic spool protector 10 may be stretched to accommodate various flange sizes. A front portion 20 of the disk-shaped member may be positioned opposite of the rear portion 26, and the front portion 20 and rear portion 26 (e.g., collectively forming a main portion of the spool protector 10) may be substantially similar in shape and size. A thickness of the main portion (said thickness extending between the front portion 20 and the rear portion 26) may be varied without departing from the scope of the present invention. In the FIG. 2 embodiment, the thickness is approximately of an inch, but such is not necessarily required in other embodiments. An aperture (e.g., center opening 24) may be included at a central portion of the spool protector 10. It will be apparent to one of ordinary skill in the art that the particular shape, location and/or size of the aperture may be varied to, e.g., accommodate any number of different wire reels or like devices.

(19) Referring to FIGS. 4-6, an exemplary spool protector 10 may be positioned on either flange 14, 16 (on either side of a spool drum 15) of a wire reel 12. The spool protector 10 may reinforce a thin, outer portion of the flange 14, 16 between a perimeter of the flange 14, 16 and an aperture 18 in the flange 14, 16. A curved rim portion of the spool protector 10 may extend around an entire perimeter of the spool protector 10, and may be configured to fit over the flange (e.g., 16). In this particular embodiment, the rim portion includes a lip portion 28 and a perimeter portion 22 positioned substantially perpendicular to the lip portion 28. It will be apparent to one of ordinary skill in the art, however, that the particular number of surfaces, and shapes, sizes, and positions thereof defining an exemplary rim portion may be varied to accommodate any number of different flanges without necessarily departing from the scope of the present invention.

(20) The lip portion 28 of the spool protector 10 may extend from the perimeter portion 22 to a lip edge 30. The lip portion 28 may contact and reinforce an outer portion of an inside face of the flange 16. The outer portion of the flange 16 may be poisoned in a receptacle between the lip portion 28 and a rear portion of the spool protector 10. The perimeter of the flange 16 may contact the perimeter portion 22 of the spool protector 10 across an entire circumference of the flange 16. The spool protector 10 may be stretched for the rim portion thereof to be positioned around the flange 16, and may constrict thereafter to be secured to the flange 16. The spool protector 10 may be positioned to substantially avoid contact with wire and/or other material to be wound to or unwound from the spool drum 15 (e.g., to prevent obstruction to said wire and/or other material).

(21) The lip portion 28 may extend approximately 0.5 inches from the perimeter portion 22 to the lip edge 30 thereof, although such is not required. In the aforementioned non-limiting example, the lip portion 28 substantially covers 0.5 inches of an outer portion of the flange 16 (0.5 inches of the outer portion of the flange 16 are positioned in the receptacle). It will be apparent to one of ordinary skill in the art that lip portion length may be varied (e.g., to accommodate different amounts of wire or other material proximate to the drum) without departing from the scope of the present invention. The receptacle is preferably narrow enough to promote substantial immobilization of the spool protector 10 over the flange 16. The elastic spool protector 10 may absorb forces directed to the flange 16 to protect the flange 16 from impact damage, may maintain proper positioning of the flange 16 to prevent the flange 16 from bending, cracking, breaking, some combination thereof, or the like, may reinforce broken and/or cracked portions of the flange 16, some combination thereof, or the like.

(22) A front portion 20 of the spool protector 10 may be positioned opposite of a rear portion 26 of the spool protector 10. The rear portion 26 may substantially cover an outside face of the flange 16, such that both the outside face of the flange 16 and the perimeter of the flange 16 are each substantially covered by the elastic spool protector 10. A center opening 24 of the elastic spool protector 10 may be configured to receive an arbor (axle, spindle, or the like) of the wire reel 12. The center opening 24 may also permit air to escape from the rear portion 26 of the elastic spool protector 10 to permit the elastic spool protector 10 to maintain high friction contact across an entire surface of the outside face of the flange 16 (e.g., without having air pockets form between the outside face of the flange 16 and the rear portion 26 of the elastic spool protector 10). The elastic spool protector 10 may comprise 3D-printed material (e.g., where 3D-printing is controlled by a computer-implemented additive manufacturing program), although such is not required. It will be apparent to one of ordinary skill in the art that any number of different techniques for assembling an exemplary elastic spool protector may be employed without necessarily departing from the scope of the present invention.

(23) Referring now to FIGS. 9-10, a wire reel 12 having two apertures 18a-b in a flange 16 thereof is shown, where the flange 16 is connected to a spool drum 15. In this particular embodiment, a crack 34 is present on the flange 16, and a portion 32 of the flange 16 edge region between an aperture 18b and a perimeter of the flange 16 is shown having been broken off from the flange (e.g., by impact damage to an unprotected flange). Referring specifically to FIG. 10, an exemplary elastic spool protector 10 may be positioned around the edge region of the flange 16. Specifically, a rear portion of the spool protector 10 may substantially cover an outside face of the flange 16, and a lip portion 28 of the spool protector 10 may extend from a perimeter portion 22 of the spool protector 10 to a lip edge 30 thereof. The lip portion 28, perimeter portion 22 and the rear portion of the wire reel protector 10 may collectively contact and reinforce the flange 16, including damaged portions 32, 34 thereof.

(24) A front portion 20 of the elastic spool protector 10 may protect the flange 16 from impact damage. The front portion 20 may surround a center opening 24 adapted to receive an arbor of the wire reel 12 (e.g., the arbor may extend through the spool drum 15). The spool protector 10 may securely constrict around the flange 16 to cover and reinforce damaged portions 32, 34 thereof. It will be apparent to one of ordinary skill in the art that an exemplary spool protector may permit continued use of any number of different damaged flanges or like components of a wire reel. It will also be apparent to one of ordinary skill in the art that an exemplary embodiment is not necessarily limited to use with a wire reel, and may be employed to protect other similar objects without departing from the scope of the present invention.

(25) Any embodiment of the present invention may include any of the features of the other embodiments of the present invention. The exemplary embodiments herein disclosed are not intended to be exhaustive or to unnecessarily limit the scope of the invention. The exemplary embodiments were chosen and described in order to explain the principles of the present invention so that others skilled in the art may practice the invention. Having shown and described exemplary embodiments of the present invention, those skilled in the art will realize that many variations and modifications may be made to the described invention. Many of those variations and modifications will provide the same result and fall within the spirit of the claimed invention. It is the intention, therefore, to limit the invention only as indicated by the scope of the claims.
