Gildart, Montebello, Califl, assignor to Rehrig Pacific Company, Los Angeles, Calif., a corporation of California Filed Jan. 12, 1968, Ser. No. 697,450 Int. Cl. 1365b 75/20, 75/22 U.S. Cl. 24277.2 12 Claims ABSTRACT OF THE DISCLOSURE A collapsible reel including wire frame end flanges which may be manually removed from the reel to permit uncoiling or stranded material wound thereon, and manually reinstalled on the reel without regard to the presence of material wound on the reel.

This invention relates to reels, and particularly to wire frame reels especially useful for handling coils of material such as electrical wire, cable, line, or the like, and which may readily be manually assembled or disassembled without regard to the presence of a coil of wire on the reel.

It is well-known in the prior art to construct a reel for carrying coils of stranded material such as wire, electricians cable, or the like (hereinafter sometimes referred to generally as cable) in the form af a frame constructed from lengths of steel rods or wire shaped into the desired configuration to support the coil. This construction will be referred to generally herein as a wire frame construction, it being understood that the Wire, or rods, used in such construction may frequently be relatively heavy and rigid rods or bars. It is also known to construct such wire frame reels in the form of a spool having removable end flange members in the manner illustrated in U.S. Patent No. 1,862,199, the normal purpose of these removable end flanges being to permit the reel to be knocked down when empty so as to occupy less space for storage.

It is also well-known to form stranded material in a coil and package the coil in a container such as a folded paperboard carton, with the material being withdrawn from the inside of the coil through a central opening cut or otherwise formed in the container. This method of packaging is commonly employed for electrical cable of the type used in household or other wiring, in which case the electrican places the coil in a central location and pulls the cable from the central opening in the carton as necessary. However, this results in the wire frequently binding, with the coil being dragged across the floor, and results in substantial wasted effort and time to free the tangled wire within the carton. Accordingly, it is a primary object of this invention to provide an improved wire frame reel for use in storing and handling coiled electrical cable and which will readily admit cable to be uncoiled therefrom over one end of the reel.

Another object is to provide an improved wire frame reel including an end flange which may readily be manually installed and/ or removed from the reel without regard to the presence of material wound upon the reel.

Another object is to provide a wire frame reel including flanges which may be manually installed and/or removed from the reel without the use of extraneous fasteners and without regard to the presence of material stored on the reel.

Another object is to provide such a reel in which such flanges may be mounted at various points axially along the length of the reel.

Another object is to provide such a reel in which a plurality of such flanges may be employed to segment the reel to permit a plurality of separate coils of material to be separately stored on the reel.

3,503,569 Patented Mar. 31, 1970 "ice Another object is to provide such a reel which may be disassembled for storage and shipment, and which may be readily and easily assembled for use.

The foregoing and other objects are attained in a reel including a wire frame spool made up of a plurality of elongated rod members supported at their opposed ends by a wire frame spider or hub member, with the radially outward ends of the hub legs rigidly secured to the ends of the rods of the spool. The end flanges of the reel are of wire frame construction and include a plurality of radially extending spoke members which may be manually deflected to resiliently engage the axial rod members of the spool to support the flanges in position on the reel. The legs of the hub engage the spokes when the flanges are installed on the reel to prevent unintentional removal of the flange. If desired, one or more stops may be provided along the length of the rod members of the spool so that a flange member may be mounted intermediate the ends of the spool to divide the reel into segments, thereby permitting a number of different coils of material to be stored in separate axially spaced areas on the reel.

Other objects and advantages of the invention will become apparent from the following specification, taken with the drawings, in which:

FIG. 1 is a perspective view of a wire frame reel according to the present invention;

FIG. 2 is an exploded view similar to FIG. 1, and showing the various components of the reel;

FIG. 3 is an end elevation view of the reel shown in FIG. 1;

FIG. 4 is a perspective view of a number of flange members shown in stacked relation for storage or shipment;

FIG. 5 is a perspective view showing wire being uncoiled from the reel;

FIG. 6 is an elevational view illustrating the reel employed to store two separate coils of wire; and

FIG. 7 is a perspective view, on an enlarged scale, of an element of the reel structure.

Referring now to the drawings in detail, a reel assembly according to the present invention is illustrated generally by the reference numeral 10, and includes a wire frame spool 11 and a pair of identical end flanges 12 mounted one on each end of the spool 11. The spool 11 is a welded wire frame structure comprising four generally parallel longitudinally extending bar members 14 supported in fixed relation to define a core for the reel upon which stranded material may be coiled. The bars 14 are retained in their spaced relation by a pair of spiders, or hubs 15 located one at each end of the reel. The hubs 15 each include four generally radially extending legs 16 each having their radially outer end connected one to the end of each of the bars 14, and each having their radially inner ends interconnected adjacent the longitudinal axis of the spool. Preferably the legs 16 of each of the hubs 15 are interconnected to form an eyelet or opening 17 along the longitudinal axis of the spool for receiving an axle or a shaft to support the reel for rotation about its longitudinal axis to permit material to be wound thereon or unwound therefrom in the conventional manner.

As best seen in FIGS. 2 and 7, the spool 11 may be fabricated from four identical preformed rod elements 18 each of which includes a pair of legs 16 integrally joined at their radially inner end by an arcuate segment 19 and having integrally formed on their radially outer end a portion 20 of the bars 14. Preferably the bar segments 20 have their terminal end bent inwardly as at 21, as will be more fully explained hereinbelow.

The spool is assembled by joining two of the preformed elements 18 together with the arcuate segments 19 in opposed overlaying relation to define the eyelet 17 of one of the hubs. Two of these subassemblies are then joined by welding together the overlapped portion 21 of the bar segments to form an inwardly directed rigid- 1y welded joint illustrated at 22 in FIG. 2. This joint 22 serves as a positive stop to limit telescoping movement of the flanges 12 axially along the bars 14 as will be more fully explained hereinbelow.

It should be pointed out that, while the spool is constructed of relatively rigid wire or bar stock, it is, nevertheless, sufliciently resilient so that the legs 16 may be manually deflected slightly to facilitate assembly and disassembly of the reel.

The end flanges 12 are illustrated in the drawings as being made up of four elongated rod elements each bent into a substantially V-shaped configuration and rigidly joined at their ends, as at 26, into a four-pointed substantially star-shaped configuration. The two

legs

30, 31 of each of the elongated bars of the flanges 12 extend radially outwardly and are joined at their outer end in fixed relation with respect to one another by an arcuate segment 32. The separate arcuate segments 32 of the flange define, in effect, the outer periphery of the flange 12, with the legs, or

spokes

30, 31 extending radially inwardly therefrom to engage and support the side face of a coil of material wound upon the reel. As used herein, the terms radial, or "radially are intended to refer to relative spacing or direction from a central point, and not as a straight line or ray extending from that central point.

As most clearly illustrated in FIG. 3, the spokes 31 of each V-shaped bar segment 25 are rigidly welded in overlapping relation to the inner end of a spoke on another of the V-shaped elements. The overlapped end portions 34 cooperate with the

spokes

30, 31 to define a V-shaped hook 36 at the radially inner end of each of the

spokes

30, 31.

While the steel bar stock or wire employed to form the spokes 30 is relatively heavy, and preferably of larger guage than that employed to form the spool 11, the spokes are, nevertheless, capable of limited resiliently resisted deflection by the application of manual pressure. Thus, by positioning one of the hooks 36 over a bar 14 adjacent the arm 16 and applying manual pressure between the spokes of the flange and successive arms around the hub, the arms and the spokes may be deflected in the plane of the flange sufliciently to permit successive hooks 36 to be positioned over the bars 14 to install a flange on the spool. The overhanging portion 34 of the spokes will then engage the arms 16 to prevent the flange from sliding axlally off the spool. By installing a second flange 12 on the spool 11, in the manner just described, the assembled reel illustrated in FIG. 1 is completed.

Referring to FIGS. 1 and 6, it is believed apparent that one of the flanges 12 may be slid axially inward from the end of the spool until the end portions 34 engage the stops 22 to position the flange adjacent the center of the spool. A third flange could then be installed on the end of the spool to complete the reel having two axially spaced segments for supporting separate coils of material.

Referring now to FIGS. 5 and 6, a coil of material such as the cable commonly employed in electrical wiring systems may be placed upon the reel, either by winding the cable directly on the reel or by removing one of the end flanges 12 and telescoping a separately formed coil onto the spool 11, and subsequently reinstalling the end flange. The cable 40 may then be unwound from the reel by inserting an axle or mandrel through the eyelets 17 of the reel and permitting the reel to rotate thereon to unwind the cable. Alternatively, the reel may be positioned on its end (one of the flanges 12) and the upper flange manually removed. The cable may then be pulled off the end of the reel, unwinding the cable from the outside of the coil as it is pulled over the end of the flange. Thus, an electrician may follow the conventional practice of positioning a coil of cable centrally within a room where he is working, and removing lengths of wire as desired merely by pulling the wire upwardly off the end of the reel. Upon completion of the job, or movement to another location, the end flange may be quickly and easily manually replaced upon the end of the spool to facilitate transportation of the cable. Any excess cable which has been removed can quickly and easily be rewound on the reel.

The embodiment of the invention illustrated in FIG. 6 may be particularly useful in instances where it is frequently desired to use two different sizes or types of stranded material. In this embodiment, it is only necessary to remove the proper flange to permit removal of the size cable desired. It is believed apparent that the reel could readily be adapted to provide three separate storage areas, in which case the cable coiled on the center area would be removed as in a conventional reel.

While I have disclosed and described a preferred embodiment of my invention, I wish it understood that I do not intend to be restricted solely thereto, but that I do intend to include all embodiments thereof which would be apparent to one skilled in the art and which come within the spirit and scope of my invention.
