This disclosure relates generally to apparatus for supporting wound flexible media, for example, cord, cable, fiber or wire.
The transport and use of cable, wire, optical fiber, and other wound media typically involves winding the flexible media on a spool or reel. Typical reels for construction purposes can have a traverse length (or axial height) of any length, and any flange diameter. Reels generally consist of a core around which the wound media is wrapped, and two flanges at opposite ends of the core.
Manufacturers or distributors of the wound media typically wind the media on the reels and deliver the reel with the wound media to customers. The customer then unwinds the media from the reel for the customer's desired use. It is undesirable if the wound media becomes tangled while being unspooled, which can occur if the reel is prone to reversing or re-winding during use.
There is a need, therefore, for a reel design that simplifies unwinding of the media and reduces the propensity of the media to become tangled.
Techniques are described herein that enable a method an apparatus that include a reel assembly and locking mechanism that can allow the reel to rotate in one direction and can disable rotation in the opposite direction. In some implementations, the reel assembly can include a single reel or multiple reels that can either rotate independently of one another or that can rotate together. The reel(s) can have a core and one or more flanges positioned on opposing ends of the reel. The flanges can have apertures that circumscribe the flange and can include a central opening that can be aligned with an outer wall of the core such that the core can pass through the central opening. Each flange can be positioned such that a portion of the core passes through the central opening and extends past the flange.
The reel assembly can include a reel stand, which can have a base and one or more end plates. Each end plate can include a cutout. The cutouts can be U-shaped and extend downwards a distance from a top edge of the end plates. The end plates can further include a locking mechanism. The locking mechanism(s) can be a plurality of protrusions that protrude from an inner face of the end plate(s). The protrusions can be radially aligned along the cutout(s) of each end plate in the same circumferential direction and can be formed as an integral portion of the material that the end plates are composed of.
In some implementations, the reel assembly can be placed into the reel stand. The portion(s) of the core that extend past the core can be positioned inside the cutout(s) in the end plates of the reel stand. The flange(s) can be positioned along the inner wall of the end plate(s). The protrusions can align with the apertures in the flanges such that the protrusions extend into at least some of the apertures. Each of the protrusions can be a flap that includes a ramp surface angled relative to the inner face of the end plate and a locking surface that is generally orthogonal to the end plate. In implementations where the protrusions are extending into at least some of the apertures, the reel can be rotated in one direction such that the ramp surface of each of the protrusions slide out of the apertures until the reel is rotated far enough that the protrusions are aligned with another set of the apertures and extend into them. When the reel is rotated the opposite direction, the locking surface braces against the aperture that the protrusion is extending into and prevents the reel from rotating.
In various implementations, the reel assembly can include multiple reels. Each adjacent reel can be joined together with a ring member that is partially nested within each adjacent reel. Each reel can be rotated independently of the other reels. The reel assembly can include multiple reel stands, each reel configured to be inserted into a respective reel stand. Alternatively, the reel assembly can include multiple intermediate disks. The intermediate disks can be a ring that is fitted around each ring member. The intermediate disks can include two sets of protrusions similar to those described with respect to the end plates. The intermediate disk protrusions can circumscribe both faces of the intermediate disk and each set can be positioned in opposing axial directions.
In some implementations, the reel assembly can be placed into a package. The package can include a window in a front face and side openings in side faces. When the reel assembly is inserted into the package, the core can be supported by the side openings of the package. A material, such as cable, wire, rope, or any other material that can be attached to the reel assembly, can be dispensed through the window.
In some implementations, the reel assembly can be mounted. The reel assembly can include an axle that has one or more endplates. Each of the endplates can be positioned at an opposing end of the axle. The endplates can include one or both of one or more mounting mechanisms, such as fastener holes, and one or more endplate protrusions.
Continuing the example from the previous paragraph, the reel assembly can include one or more reels mounted on the axle. Each of the reels can include a core portion. The core portion can be, for example, a longitudinally extending core. The axle can run through each of the core portions such that the reels become mounted on the axle.
One or more of the cores can have one or more flanges positioned at opposing ends of the core. One or more of the flanges can have one or more apertures that are radially aligned along the flange. For example, a reel assembly can include three reels mounted on the axle. The first reel can have a flange that includes one or more apertures. The third reel can also have a flange that includes one or more apertures. These flanges can be the exterior flanges that are located most closely to the endplates, such that one or more of endplate protrusions protrude away from each respective endplate and into one or more of the apertures of the flange of the first reel and/or into one or more of the apertures of the flange of the third reel.
The first reel and the third reel can each include an additional flange. The additional flanges can be considered interior flanges, because they are positioned between the two exterior flanges. The second reel can also include two interior flanges. Each of the interior flanges can include a cutout portion and/or one or more tabs. The tab(s) and the cutout portion(s) of adjacent flanges can interact with one another such that the tabs, when aligned with the cutout portion, can extend into the cutout portion and rotationally lock the two adjacent reels together. For example, a flange of a first reel can include cutout portion that interacts with a tab that is positioned on a flange of a second reel. When the tab(s) of the second reel is protruding into the cutout of the first reel, a rotation of either the first reel or the second reel will cause a rotation of the either the second reel or the first reel, respectively. The second reel and the third reel can interact in a similar way. In some implementations, one or more of the interior flanges can have both a cutout portion and one or more tab(s), while the exterior flanges can lack both a cutout portion and one or more tab(s).
With continuing reference to
One or more of the flanges 124 can be an annular disk. The flanges 124 can include a central opening 140 and/or a one or more apertures 144. In some implementations, one or more of the apertures 144 can be radially aligned along the central opening 140. Each of the apertures 144 can be evenly spaced. The flanges 124 can be formed of corrugated material (e.g. cardboard), plywood, chipboard, wood, or paperboard. In other embodiments, the flanges 124 can be formed of polypropylene plastic, polyethylene, polycarbonate, ABS, polystyrene, nylon, a combination of one or more of the aforementioned materials, or another desired material.
The flanges 124 can be fixed to the core 120 such that the core 120 passes through the central opening 140 of the flanges 124. For example, the core 120 can extend beyond the flanges 124 by a distance that is substantially equal to or greater than the thickness of the material of the reel stand 116. In some embodiments, the core 120 cam be glued to the flanges 124, while in other embodiments the core 120 may be attached to the flanges 124 using fasteners (e.g., screws, staples, or other fasteners), a press-fit or interference-fit, or welding (e.g., via a plastic welding process such as induction welding), or fixedly connected to the flanges 124 in another suitable manner.
The reel stand 116 can include a base portion 152 and one or more end plates 156. The end plates can extend upwardly and generally orthogonally from a respective end of the base portion 152. The reel stand 116 may be formed of corrugated material. Alternatively, the reel stand 116 can be formed of another suitable material such as plywood, chipboard, wood, paperboard, metal, or plastic.
A distance between the end plates 156 of the reel stand 116 can be slightly greater than a distance between the flanges 124. The distance between the end plates 156 can be generally equal to or less than the axial length of the core 120.
One or more of the end plates 156 can include a cutout 160, where the cutout 160 can be an area of the end plates 156 that appears to be missing, or where no material is present. For example, the cutout 160 can open toward the top of the reel stand 116. The cutout 160 can be sized to accommodate the core 120 such that the core 120 can be nested inside the cutout 160. Specifically, the portions of the core 120 projecting beyond the end surface of the respective flange 124 rest on a base portion of the cutout 160 such that the cutout 160 supports the core 120 and allows the core 120 to rotate relative to the reel stand 116. In some implementations, the cutout 160 can be generally U-shaped. The cutout 160 can also include a flared portion near the top of the end plate 156. The flared portion of the cutout 160 can guide the core 120 into the cutout 160 when the core 120 is being placed into the reel stand 116. Alternatively, the cutout 160 can be oval, circular, rectangular, or any other shape necessary to accommodate the core 120.
The packaged reel assembly 100 can include a package 108 that the reel 112 and reel stand 116 can be secured inside of. The package 108 can be a standard box that has a base, front and rear walls, and two side walls. The package 108 can have substantially the same dimensions as the reel stand 116 such that the reel stand 116 can be arranged within the package 108 with little or no play. The package 108 may be, for example, a corrugated box or other suitable package. The package 108 can include a window 180 in a front or rear wall through which a wound media on the reel 112 can be unwound by a user. Additionally, in some embodiments, the package 108 can include openings 184 on each side wall to enable portions of the core 120 that extends beyond the flanges 124 to be further supported by the package 108.
In use, the reel 112 can be wound with the media and then arranged such that each end of the core 120 rests within a respective one of the cutouts 160 of the reel stand 116. The reel stand 116 can then be placed in the package 108, which can then be closed for transport to the end-user.
In
One or more of the protrusions 164 can have a ramp surface 168 on one circumferential end thereof (on the end facing toward the counter-clockwise direction in the view of
The protrusions 164 can be arranged at essentially the same radius from the central axis 132 as the apertures 144 in the flanges 124 and can be spaced apart from one another the same spacing as the apertures 144. The protrusions 164 can be oriented in a particular circumferential direction relative to a center point. As a result, when the apertures 144 are aligned with the protrusions 164, the protrusions 164 can extend partially into the respectively aligned apertures 144 to limit rotation of the flanges 124 relative to the reel stand 116 in one direction, thereby forming a reel locking arrangement. In some embodiments, one or more of the protrusions 164 can be generally U-shaped.
In some implementations, the protrusions 164 are integral members of the end plate 156. The protrusions 164 may be formed, for example, by a die cutting process in which the shape of the protrusions 164 is cut through the material of the end plate 156 and the resulting flap is pressed from the opposite side of the material such that the flap projects from the axially inward side of the end piece 156. In other embodiments, the protrusions 164 may be formed by stamping, thermoforming, vacuum forming, pressure molding, injection molding, embossing, or another desired process. Alternatively, the protrusions 164 can be individual pieces that are attached to the end plate 156.
To use the packaged reel assembly 100 as depicted in
Once the user stops pulling the media through the window 180, the reel 112 can cease to rotate relative to the reel stand 116 due, in part, to the friction between the protrusions 164 and the flanges 124 and, potentially, the engagement between the ramp surfaces 168 and the edges of the apertures 144 in the end plates 156 of the reel stand 116. The protrusions 164 can snap into corresponding apertures 144 as the reel 112 ceases to rotate. If rotational force is applied to the reel 112 in the reverse direction, or in other words in the winding direction (i.e., counterclockwise as viewed from the right in
The reel assembly 204 can further include one or more reel interfaces 228A and 228B. Each respective reel interface 228A and 228B can be arranged between each adjacent pairs of reel portions 212A-B and 212B-C. Each reel interface 228A-B can include an intermediate disk 232A-B and a ring member 236A-B. The ring members 236A-B can each be partially nested within each of the two adjacent core sections 220A-B and 220B-C such that the middle core portion 220B is supported by the two outer core portions 220A, 220C while being rotatable relative to the outer core portions 220A, 220C. For example, the ring members 236A-B can be cylindrical and have a diameter that is slightly less than the diameter of the core sections 220AC, such that the ring members 236A-B can be positioned inside of the core sections 220A-C with a tight fit. The intermediate disks 232A-B can be interposed between and in contact with the two adjacent flanges 226A, 224B and 226B, 228A, respectively. In some embodiments, the intermediate disks 232A-B can be fixedly connected to the reel stand 116 such that the intermediate disks 232A-B do not rotate.
In various embodiments, the reel assembly 204 can include three reel portions 212A-C. However, the reel assembly 204 can alternatively include any two of the reel portions 212A-C. For example, the reel assembly 204 can include only portions 212A-B, 212B-C, or 212A and C. In these embodiments, any of the joined reel portions 212A-C still include the general structure described above. In other embodiments, the reel assembly 204 may include reel portions and accompanying structure in addition to reel portions 212A-C.
The intermediate disks 232A-B are illustrated in more detail in
The protrusions 244 and 248 can be formed in the same ways as the protrusions 164 as described with respect to
As a result, when media on the reel portion 212A is pulled in the unwinding direction, the apertures 144 in the outer flange 224A can rotate relative to the protrusions 164 of the end plate 156 of the reel stand 116 in a manner similar to the embodiment of
When the media on the reel portion 212B is unwound, the apertures 144 on both flanges 224B, 226B can move along the ramp surfaces of the protrusions 248, 244 of the respectively adjacent intermediate disk 232A, B, thereby allowing the flanges 224B, 226B to move relative to the intermediate disks 232A, B. As a result, the reel portion 212B can be unwound without also unwinding the reel portions 212A or 212C.
When force is applied to the reel portion 212B in the winding direction, the apertures 144 of the flanges 224B, 226B can engage with the locking surfaces 172 of the protrusions 248, 244 of the adjacent intermediate disks 232A, B. The protrusions 244, 248 on the opposite sides of the intermediate disks 232A and 232B can then engage with the apertures 144 of the associated flanges 226A, 224B and 226B, 224C, respectively, which apply the rotational force in the winding direction to the end reels 212A, 212C. The end flanges 224A, 226C, however, can be locked from rotation in the winding direction by the locking surfaces 172 of the protrusions 164 of the reel stand 116. Consequently, since the reel portion 212B is rotationally fixed relative to the end reel portions 212A, C, and the end reel portions 212A, C are rotationally fixed relative to the reel stand 116, the middle reel portion 212 can be prevented from rotating in the winding direction.
Accordingly, in the embodiment of
Alternatively, in a variation of the embodiment of
The reel assembly 204A of
In the embodiment of
Each of the one or more reel portions 304A-C can include one or more flanges 320A-B, 324A-B, 328A-B, respectively, and a core portion 332, 336, 340, such as a longitudinally extending cylindrical core. The core portions 332, 336, 340 can be supported on the axle 312 such that they are rotatable about the axle 312. For example, the axle 312 can be inserted through each of the core portions 332, 336, 340, such that the reels 304A-C can be rotated about the axle 312.
Each pair of flanges 320A-B, 324A-B, 328A-B can be fixedly connected to the respective core portion 332, 336, 340. Each respective flange of each pair of flanges 320A-B, 324A-B, 328A-B can be positioned at opposing ends of the respective core portion 332, 336, 340. For example, flange 320A can be positioned at a first end of core portion 332, while flange 320B can be positioned at a second end of core portion 332. Additionally and/or alternatively, one or more of the flanges 320A-B, 324A-B, 328A-B can include one or more apertures 344. For example, flanges 320A, 328B, which are exterior flanges positioned closest to the endplates 308, can include a plurality of apertures 344. The apertures 344 can be radially aligned around a central flange opening and/or can be spaced around the circumference of the flanges 320A-B, 324A-B, 328A-B. The spacing of the apertures 344 can be similar to the spacing of the protrusions 318 of the end plates 308. In some embodiments, all of the flanges 320A-328B can include the apertures 344. In some implementations, one or more of the flanges 320A-B, 324AB, 328A-B may not include the apertures in some embodiments. For example, flanges 320B, 324A-B, 328A, which are interior flanges that are not nearest to the endplates 308A may not include the apertures 344.
One or more of the flanges 320A-B, 324A-B, 328A-B can include one or more cutouts 348 and/or one or more tabs 352. For example, each of the interior flanges 320B-328A can include a cutout 348 and a pair tabs 352. The tab(s) 352 of a respective flange 320A-B, 324A-B, 328A-B can align with the cutout 348 of an adjacent flange 320A-B, 324A-B, 328A-B. The tab(s) 325 of a particular flange 320A-B, 324A-B, 328A-B, when aligned with the cutout 348 of an adjacent flange 320A-B, 324A-B, 328A-B, can extend into the cutout 348 and rotationally lock two of the reel portions 304A-C together. For example, a pair of tabs 352 on flange 324B can align with a cutout 348 of flange 328A to rotationally lock reel portions 304B and 304C together. In some implementations, one or more of the flanges 320A-B, 324A-B, 328A-B can include both a cutout 348 and one or more tabs 352. For example, flange 324B can include a pair of tabs 352 and a cutout 348. In these implementations, an adjacent flange 320A-B, 324A-B, 328A-B, for example flange 328A, can also include a cutout 348 and a pair of tabs 352. In this way, the tabs of flange 324B can align with the cutout 348 of flange 328A and vice versa. This alignment can occur simultaneously or at different times to provide another rotationally locked position for one or more of the reels 304A-C.
For example, when the tabs 352 of the flanges 320B, 324A are inserted into the associated cutouts 348, the middle reel portion 304B can be locked for rotation with the outer reel portion 304A. Likewise, when the tabs 352 of the flanges 324B, 328A are inserted into the associated cutouts 348, the middle reel portion 304B can be locked for rotation with the outer reel portion 304C. As a result, the user can selectively configure the reels such that the middle reel portion 304B rotates independently of the outer reel portions 304A, 304C, or that the middle reel portion 304B rotates together with the outer reel portion 304A or with the outer reel portion 304C. Alternatively, the user may join all three reel portions 304A-C together using the tabs 352 and cutouts 348 such that the media on all three reel portions 304A-C can be unwound together.
The cutout(s) 348 can be a variety of shapes. For example, the cutout(s) can be rectangular, circular, triangular, or any other functional shapes that facilitates the functions described herein. The tab(s) 352 can also and/or alternatively be a variety of shapes as well. For example, they can have cross section that is triangular, rectangular, trapezoidal, circular, cylindrical, or any other functional shapes that facilitates the functions described herein. The tab(s) 352 can be integral with the flanges 320A-B, 324A-B, 328A-B. For example, the tab(s) 352 can be a flap that is cut from the flange 320A-B, 324A-B, 328A-B, itself. Alternatively, the tab(s) 352 can be an additional piece that is attached to the flanges 320A-B, 324A-B, 328A-B. The tabs(s) can be formed in the same way as the protrusions described above with respect to
In some embodiments, the protrusions 318 of the end plates 308 and the apertures 344 of one or more of the flanges 320A-B, 324A-B, 328A-B, for example the outer flanges 320A, 328B, can engage in a similar manner as in the embodiments described above. Thus, the one or more of the reel portions 304A-C, such as the outer reel portions 304A, 304C can rotate in the unwinding direction, and can be disabled from rotating in the winding direction.
Additionally or alternatively, in some implementations, an intermediate disk such as the intermediate disk 232 of
It will be appreciated that the above-described implementations are merely illustrative, and that those of ordinary skill in the art may readily devise their own modifications and implementations that incorporate the principles of the present invention and fall within the spirit and scope thereof.
