The present disclosure relates generally to improved systems and methods for industrial reels, and more particularly, to an improved assembly, disassembly and locking mechanism for industrial reels.
In general, industrial reels often include a barrel and two flanges which connect to the barrel. Industrial materials such as wire, cable, tubing, rope, yarn, or the like may be wound onto the barrel of the reel. The reel can be taken apart (i.e., the flanges removed from the barrel) during shipping or after use, for example, to conserve space and minimize shipping costs.
Typically, industrial reels are assembled using a chemical solvent that is hazardous to people and the environment. In other cases, the flanges and barrel of the reels twist and lock together with integral holding snaps on the flange that are very stiff in order to maintain the barrel/flange connection during winding and unwinding. To remove the flanges from the barrel, a user must lift the snaps that lock the reel parts together, often using a specialized tool to pry the snap away from the barrel because the force required to lift the snaps is greater than can be achieved manually with a finger. This is undesirable because users generally prefer to avoid purchasing, managing, and using special tools where possible.
Through ingenuity and hard work, the inventors have developed an industrial three-piece reel having an efficient and effortless locking and alignment mechanism located on the barrel and at least one of the flanges of the reel that does not require the need for chemicals or a specialized tool to assemble, disassemble and/or lock.
In an embodiment, the invention comprises an industrial reel having a spool comprising a cylindrical hub, a first spool flange positioned at a first end of the cylindrical hub and a second spool flange positioned at a second end of the cylindrical hub, the first spool flange and the second spool flange projecting radially from the cylindrical hub. The industrial reel further includes at least one first insert removably affixable to the first spool flange. The at least one first insert comprises a first cylindrical barrel having a first longitudinal end and a second longitudinal end, wherein the second longitudinal end includes at least one or more castellations. The at least one first insert further comprises a first insert flange extending from the first longitudinal end of the first cylindrical barrel, wherein the first insert flange is removably affixable on a radially outward edge thereof to a radially outward edge of the first spool flange.

Having thus described the present disclosure in general terms, reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
While this present disclosure may be embodied in many forms, there is shown in the drawings and will herein be described in detail one or more embodiments, with the understanding that this disclosure is to be considered an exemplification of the principles of the present disclosure and is not intended to limit the disclosure to the illustrated embodiments.
Generally speaking, the present invention is directed to an industrial reel, defined by a barrel, or hub, having a central axis, an interior surface and an exterior surface, the exterior surface forming a barrel surface for receipt of a wire, a cable, or the like for winding thereon. The hub, in an embodiment, has a flange disposed at each longitudinal end. The reel has at least one first insert formed separately from the spool. In a particular embodiment, the reel has two inserts formed separately from the spool, each of which can be inserted into an opposite end of the hub and locked into position with each flange.
In one aspect of the present invention, the industrial reel includes a locking mechanism. In an embodiment, the locking mechanism includes at least one or more insert tabs positioned on the at least one first insert, configured for locking into at least one or more slots positioned on a first flange of the spool. In an embodiment, other types of locking mechanisms are contemplated. In another aspect of the present invention, the industrial reel further includes an alignment mechanism between the at least one first insert and a second insert. In an embodiment, the alignment mechanism allows the first and the second insert to lock into each other through the interior surface of the spool hub. The spool and/or insert(s) may comprise integrally molded thermoplastic material and the spool hub may be substantially centrally hollow, the hollow portion defined by the interior surface of the winding surface.
Other features of the present invention and combinations of features will become apparent from the detailed description below, taken in conjunction with the accompanying drawings.
As depicted in
In an embodiment, as depicted in
While two inserts 12, 13 are shown in the figures, in some embodiments, a functional reel 10 may include only a single insert having a cylindrical barrel and an insert flange removably affixable to a spool flange, if desired. Additionally, as shown in
In some embodiments, the radially outward edge of the first spool flange 22 comprises a sidewall 23 that is perpendicular to an inner surface 22a of the first spool flange 22 (see
In an embodiment, the radially outward edge of the first insert flange 32 and the radially outward edge of the second insert flange 33 each comprise a sidewall 32a, 33a, that is perpendicular to an inner surface of the insert flange 32, 33. Additionally, in an embodiment, the sidewalls 32a, 33a each comprise at least one or more insert tabs 36, 37. In certain embodiments, the at least one or more insert tabs 36 of the first insert flange 32 is configured to interlock with the one or more slots 26 positioned within the sidewall 23 of the first spool flange 22. In certain embodiments, the at least one or more insert tabs 37 of the second insert flange 33 is configured to interlock with the one or more slots 27 positioned within the sidewall 25 of the second spool flange 24.
In an embodiment, the shape of the at least one or more insert tabs 36, 37 may be generally square, rectangular, triangular, ovular, circular, elliptical, a combination thereof, or any other shape known in the art. While in the figures the at least one or more insert tabs 36, 37 are depicted as having two side-by-side insert tabs, in certain embodiments there may only be one insert tab, while in other embodiments there may be multiple insert tabs disposed on the sidewalls 32a, 33a. In some embodiments, as shown in
In an embodiment, each of the at least one or more insert tabs 36, 37 may include at least one of an upper face 36a, a lower face 36b, two side faces 36c and, optionally, a forward face 36d. In some embodiments, the lower face 36b may be curved or angled such that the lower face 36b directs the tab 36 into a respective slot. In this embodiment, the lower face 36b may contact the inner surface of sidewall 23 in an interference fit and slide along said inner surface until reaching the slot 26. The lower face 36b may then slide into the slot 26 until such time as the upper face 36a of the tab 36 enters the slot 26. In an embodiment, the configuration of the upper face 36a does not permit removal of the tab 36 from the slot 26 without the application of external forces. That is, in an embodiment, the upper face 36a of the tab 36 may be flat and may interface with an upper edge of the slot 26. In an embodiment, an audible click may be observed upon locking of the insert tab 36 into the slot 26, as the tab 36 flexes back to its original biased configuration and contacts the sidewall 23 of the first spool flange 22. In some embodiments, the at least one or more insert tabs 36, 37 may include any configuration of the at least one of the upper face 36a, the lower face 36b, the two side faces 36c and the forward face 36d.
In certain embodiments, the first insert flange 32 and the second insert flange 33 may include as many insert tabs as necessary depending on the desired use of the industrial reel 10. In some embodiments, the more slots and insert tabs placed on the spool 11 and inserts 12, 13 of the reel 10, the more secure the locking mechanism of the reel 10 may be, as described in greater detail below. While in the figures the at least one or more slots 26, 27 and the at least one or more insert tabs 36, 37 are rectangular in shape, the at least one or more slots 26, 27 and the at least one or more insert tabs 36, 37 may be circular, triangular, or any other shape desired. In some embodiments, the shape and configuration of the at least one or more slots 26, 27 positioned within the sidewalls 23, 25 may match the shape of the at least one or more insert tabs 36, 37.
In some embodiments, at least one or more slots may be positioned on the radially outward edge of the first insert flange 32 and the radially outward edge of the second insert flange 33, while at least one or more insert tabs may be positioned on the sidewall of the first spool flange 22 and the second spool flange 24. In further embodiments, the one or more slots 26, 27 and the one or more insert tabs 36, 37 may be placed on another location on the reel 10 other than the first and the second spool flange 22, 24 and the first and the second insert flange 32, 33. In certain embodiments, for example, at least one or more slots may be positioned within the inner surface 20a of the cylindrical hub 20 near the first and the second end of the cylindrical hub 20c, 20d while at least one or more insert tabs may be placed on an inner surface of the first and the second cylindrical barrels 30, 31 of the first and the second insert 12, 13. In other embodiments, the spool 11 may comprise both at least one or more slots and at least one or more insert tabs while the first and the second inserts 12, 13 may also include the same counterparts, i.e., a slot interlocking with an insert tab and insert tab interlocking with a slot.
In an embodiment, the industrial reel includes a locking mechanism. In certain embodiments, the locking mechanism includes the at least one or more insert tabs 36 of the first insert flange 32 locking into the at least one or more slots 26 of the first spool flange 22 (see
As depicted in
In an embodiment, when the at least one or more castellations 38, 39 of the first insert and the second insert 12, 13 align, the first insert 12 and the second insert 13 are able to lock into each other and extend through the interior surface 20a of the cylindrical hub 20. Thus, the diameter of the first cylindrical barrel 30 and the second cylindrical barrel 31 is smaller than the diameter of the cylindrical hub 20 of the spool 11, so that the first cylindrical barrel 30 of the first insert 12 may lock into the second cylindrical barrel 31 of the second insert 13 and extend through the interior surface 20a of the cylindrical hub 20.
Furthermore, in an embodiment, the first spool flange 22 and the second spool flange 24 each further comprise at least one or more ribs 28 protruding from the sidewalls 23, 25 of the first and the second spool flange 22, 24 and extending to the inner surface of the first and the second spool flange 22, 24 (see
In an embodiment, the at least one or more insert tabs 36, 37 may be removed from the at least one or more slots 26, 27, and thus the first and the second insert flange 32, 33 may be detached from the first and the second spool flange 22, 24, in order to, for example, disassemble the reel 10. In an embodiment, once the at least one or more insert tabs 36, 37 have locked into the at least one or more slots 26, 27 a user may insert the top of his finger, or even a fingernail, near the top of the sidewalls 32a, 33a and apply pressure inwardly, towards the central axis, in order to move the at least one or more insert tabs 36, 37 towards the central axis of the first and the second insert 12, 13. In some embodiments, once the at least one or more insert tabs 36, 37 have been moved far enough inwardly so that the at least one or more insert tabs 36, 37 is no longer in contact with the at least one or more slots 26, 27, the user may then lift the first and the second insert flange 32, 33 upward to detach the first and the insert 12, 13 from the first and the second spool flange 22, 24, and thus the spool 11. In some embodiments, the same motion may be applied to at least one or more insert tabs positioned on the extension elements 34. In other embodiments, when in a locked position, the at least one or more insert tabs 36, 37 may protrude out of the at least one or more slots 26, 27. Thus, in these embodiments, to detach the one or more insert tabs 36, 37 from the one or more slots 26, 27 the user may apply pressure using his fingers at the location of the protruded insert tabs to move the at least one or more insert tabs 36, 37 inwardly, towards the central axis and remove the at least one or more insert tabs 36, 37 from the one or more slots 26, 27.
In an embodiment, the structures of the present invention be formed with a minimum number of parts. Thus, in an embodiment, the completed reel 10 may have a single insert flange and spool flange. The elements of the reel 10 are also contemplated to be injection molded from a thermoplastic material, such as styrene, an olefin or combination of polymer materials. Further, the structures of the cylindrical hub 20, and the first and the second insert flange 32, 33 may be integrally molded. The surfaces and structural elements of the molded parts may be arranged to allow for withdraw of the mold sections from the parts with a minimum of movements and mold sections.
