Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates generally to the field of material storage and to storage devices used for storage and transport of flexible materials, particularly cable, rope, hoses, wire or cord.

2. Description of the Related Art

Reels and similar devices comprise primarily a spool upon which flexible materials may be wound and stored or transported. The stored material is normally flexible enough to allow it to be wound around the spool. The addition of flanges attached to both ends of the spool prevents the material from falling off the edge of the spool, as well as aides in winding the material in the most efficient manner possible.

The need for spools is quite great, and a variety of materials are stored and subsequently transported on spools. Cables, ropes, hoses and wire are just a few examples of the materials, mechanisms and systems that benefit from the use of spools and similar storage devices. Currently, reels and spools are manufactured almost completely by companies that specialize in the manufacture of these devices. These reel producing companies typically manufacture the flanges, the spool or tube portions, and the fasteners that connect the flanges to the spool portion. These reel producing companies also typically provide the labor for assembly, and then ship the completed reels to the end user for their specific application.

Not surprisingly, reel manufacturing is limited by geographies and considering as fully constructed reels are extremely bulky, and there is no simple solution for long distance shipping within most businesses. In addition, companies that use reels typically do not assemble their own reels due to the number of variables and components required to manufacture customized reels.

Various solutions have been introduced attempting to simplify the problems associated with flexible material storage. For example, U.S. Design Pat. No. D370,908 to Weisburn et al., discloses an ornamental design for a tape reel flange. The drawings appear to illustrate levers along with tabs that include holes, ostensibly to lock the flange to a hub.

U.S. Pat. No. 3,239,159 to Cohen, discloses a tape-collecting reel designed to decrease inertia of the device by providing cut outs in the flange portion. The reel is designed to be assembled and disassembled quickly and easily by the removal of flange discs on either end of the reel. The flanges include keyholes that contain enlarged openings at the end of narrow slots. This arrangement allows a locking pin to be inserted, and then locked in place with rotation of the disc flange.

U.S. Pat. No. 5,114,089 to Posso, discloses another tape reel that includes detachable flanges and a means for locking the flanges to the hub. The locking mechanism comprises a series of axially positioned tabs that are placed over locking bars. By rotating the flange, the locking bars engage the tabs thereby locking the flanges in place.

U.S. Pat. No. 5,806,788 to Witwer, et al., discloses a so-called knockdown reel assembly. The term “knockdown” refers to the ability of the reel to be collapsed for easy storage and transport. The device includes a drum and end flanges that combine to form the reel. The end flanges include an interior disc portion that is attached to the flange. The drum segments then slide over and lock onto this disc portion of the end flanges to provide a locked assembly. The entire device may be made from any suitable lightweight plastic material.

U.S. Pat. No. 6,045,087 to Vislocky, et al., discloses a spool with snap fit flanges. The spool is capable of quick and easy assembly by means of locking tabs that will snap into place when properly aligned and inserted within receiving portions on the hub. The alignment of the flanges with the receiving portions is further simplified by means of a guide comprising a notch in the end of the hub that allows the flange to be inserted in only one position. This alignment tool is designed to take out any guesswork that might be involved with attaching the flange to the hub.

U.S. Pat. No. 6,089,500 to Häfner, discloses a collapsible spool that includes what are termed bayonet couplings. The couplings allow for easy assembly of the flanges to the hubs, simply by placing the flange on the hub, and rotating to a locked position. Additional stability can be achieved by inserting locking plugs into holes that will be available only when the flange is properly aligned with the hub in a locked position.

U.S. Pat. App. No. 2002/0053625 to Charlton, discloses a demountable cable reel that is also designed to provide quick and easy assembly and disassembly without having to remove the cable from the hub. This feature is particularly useful in the event that one of the flanges becomes damaged and must be replaced. The locking mechanism that this device employs is a fairly straightforward gear tooth style configuration. The portion resembling a gear is attached to the flange and inserted within a mirror-image style cut out of the gear. By rotating the flange, the extensions of the gear shaped element are thereby locked into position relative to the hub. A locking pin may also be employed for additional stability.

In summary, investigation of these disclosed devices illustrates that presently, there is no single device known in the art that meets the requirements of a storage and transport device for flexible material that includes the unique structure of the present invention, and its inherent benefits.

Once each storage and transport device 10 is assembled, the structure of each device 10, allows for multiple devices 10 to be stacked atop one another flush for more convenient storage and transport. This is accomplished by placed the second flange 18B of one assembled device 10 atop the first flange 18A of another assembled 10, wherein the bottom locking tabs 30 of the second flange 18B of one assembled device 10 are placed in the top locking tab receiving means 50 of the first flange 18A of another assembled device 10. The tab receiving means 50 contain a void after rotation and locking of each flange 18A and 18B to the cylindrical core 12, such that the tab receiving means 50 are able to couple with either the top or bottom locking tabs 22 and 30 of another assembled device 10.

The ease with which the present invention may be constructed should now be readily apparent. Many such devices may be shipped, disassembled in bulk to the end user. The device may then be easily and efficiently stored as desired, or put immediately into service with minimal labor. Cost will further be reduced because a larger number of disassembled devices may be shipped then assembled reel devices produced by other manufacturers. The size, both diameter and length of the device may be varied depending upon the application. In addition, a variety of materials may be utilized, including plastic molds for the tube portions, and flanges comprised of wood materials.

Although the present invention has been described with reference to particular embodiments, it will be apparent to those skilled in the art that variations and modifications can be substituted therefore without departing from the principles and spirit of the invention.
