Abstract:
A caddy for storage and transportation of a heavy-duty electrical extension cord, the caddy comprising a reel mounted inside a protective container. A cord is wound on the reel for storage and subsequently unwound for use, the tendency for tangling and twisting characteristic of hand-coiled cords is avoided. Storage inside the container protects the cord against damage during transportation.

Description:
BACKGROUND OF THE INVENTION 
     The storage and transporting of relatively long heavy-duty electrical extension cords presents a number of problems. Typically the cord is coiled by hand after use, then thrown in a heap or hung on a hook between periods of use. When it is subsequently uncoiled for use, it tends to twist and tangle so that its extension for use becomes a difficult and often a frustrating experience. The cord is especially subject to damage during storage and transportation from one work site to another. 
     The present invention relates to a caddy for transporting and storage of a heavy duty electrical extension cord mounted inside a container. The cord is taken up by a reel mounted inside a container as the reel is turned by means of a crank. The cord is subsequently unwound from the reel as it is withdrawn through an opening in the side of the container. The container has a handle which serves as a convenient means for carrying the container and the container protects the cord against damage and dirt during storage. 
     DESCRIPTION OF THE PRIOR ART 
     Various open-reel type devices are known for storage and transportation of electrical extension cords, but none are known in which the reel is mounted as claimed herein inside a protective container wherein a length of electrical cord at its input end is available for connection to a power outlet without completely unwinding the cord. 
     SUMMARY OF THE INVENTION 
     In accordance with the present invention, an electrical extension cord caddy comprising a reel mounted inside a protective container is provided wherein the cord is wound up on a reel as the reel is turned by use of a removable hand crank. The cord and reel are transported and stored inside the container until needed at which time the cord is at least partially withdrawn through an opening in the side of the container. 
     It is, therefore, one object of this invention to provide a new and improved caddy for a heavy-duty electrical extension cord. 
     Another object of this invention is to provide such a caddy in a form which incorporates a storage reel inside a protective container. 
     A further object of this invention is to provide such a caddy in a form which prevents the cord from becoming twisted and tangled during storage and during its extension for use. 
     A still further object of this invention is to provide such a caddy with a container that is designed to facilitate its being carried by one hand and at the same time affording effective protection of the cord during its storage and transport. 
     Yet another object of this invention is to provide such an electrical extension cord caddy in a form which permits the connection of its plug and its source end to an electrical outlet without completely unwinding the cord from the reel. 
     Further objects and advantages of the invention will become apparent as the following description proceeds and the features of novelty which characterize the invention will be pointed out with particularity in the claims annexed to and forming a part of this specification.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring more particularly to the drawing by characters of reference, FIGS. 1-4 disclose an electrical extension cord caddy 10 of the invention, the caddy 10 comprising a container 11, a reel 12, a container cover 13, and a hand crank 14. 
     Container 11 has the form of a bucket, preferably cylindrically shaped, with a handle 15 mounted on one end of the container for carrying purposes. A circular opening 16 on one side of container 11 provides passage for the extension cord 17 during storage and withdrawal of the cord. In a first embodiment of the invention, a five gallon plastic bucket was employed for the container. 
     Reel 12, as shown in FIGS. 2, 3 and 4, comprises a circular base 18, a hollow cylindrical spool 19 having a diameter approximately one-third that of container 11 and a cylindrical shaft 21. The spool 19 and shaft 21 are concentric with the cylindrical form of container 11, both rising vertically from their centered positions upon the horizontally oriented circular base 18. As shown in FIGS. 3 and 4, spool 19 and shaft 21 are preferably made of plastic and integral with base 18, but the reel may be fabricated by cementing together lengths of commercially available plastic tubing and various plastic fittings. 
     Reel 12 is mounted inside container 11, as shown in FIG. 2, where it is rotatably secured to the bottom of container 11 by means of a Lazy Susan bearing 22. 
     Lazy Susan bearing 22 has an upper plate 23 and a lower plate 24 which are rotatably secured to each other with the aid of a circular trace of ball bearings 25 (see FIG. 4). The upper plate 23 is secured to the underside of base 18 of reel 12 by means of screws 26 and the lower plate 24 is secured by screws 27 and nuts (not shown) to the bottom of container 11. The reel 12 is thus free to rotate inside container 11. 
     Crank 14 has a rotatable knob 28 at its outer end and a quick-disconnect couple member 29 at the other end which mates with a second disconnect member 31 that is rigidly secured to the top of shaft 21. 
     Container cover 13 fits over the circular opening of container 11 and has a circular central opening through which the upper end of shaft 21 and disconnect member 31 pass when cover 13 is installed. As shown in FIG. 2, crank 14 must be removed prior to the removal of cover 13. 
     When the extension cord 17 is initially installed in caddy 10, its plug end 33 is passed through opening 16 of container 11 and through an opening 34 in the wall of reel 12 into the hollow space inside reel 12. A length of cord that is deemed long enough to reach the typical outlet location is drawn through opening 34 and is stored inside reel 12 by spiraling around shaft 21 and about the inside surface of reel 12. Cover 13 and hand crank 14 are then put in place as shown in FIG. 1. When this has been done, crank 14 is turned as indicated by arrow 35 causing the reel 12 to rotate, thereby taking up cord 17 as indicated by arrow 36. The entire cord is taken up in this manner except for a short length (three to six inches) which needs to be grasped when the cord is subsequently extended for use. 
     When the cord is to be extended for use the short end of cord 17 extending from the caddy is grasped and the desired length of cord is drawn from the caddy, the reel turning to unwind the cord as the cord is drawn from the caddy. When the cord is stored and withdrawn in the manner just described, there is no tendency for the cord to become twisted or tangled. After the desired length of cord has been withdrawn, crank 14 and cover 13 are removed and plug end 33 of the cord is removed from its storage space inside reel 12. The cord is then plugged into a power source and is ready for use. 
     Following such use, plug end 33 is again stowed inside reel 12, the cover 13 and crank 14 are installed, and crank 14 is operated to take up the cord as described earlier. The caddy may be conveniently carried to a storage shed or to a truck using the container handle 15. 
     Although but a single embodiment of the invention has been illustrated and described, it will be apparent to those skilled in the art that various changes and modifications may be made therein without departing from the spirit of the invention or from the scope of the appended claims.
