Description
- 1. Field of the Invention
- The present invention relates generally to devices and methods for storing electrical cords, such as extension cords, and in particular, to a device and method for winding electrical cords into a coil shape for storage.
- 2. Description of the Related Art
- Extension cords are used in many households to connect electrically operated devices that are operated at a distance from an electrical outlet. For example, weed cutters, power hedge clippers, holiday lights, and portable generators are often used with long extension cords. Such extension cords are often difficult to handle, especially when a homeowner attempts to place the cords into a coil shape for storage. For example, common handling of extension cords often results in tangling and twisting of the cords and generally haphazard storage.
- Electric extension cords are more convenient to store when they are placed into a coiled shape. Various holders have be used for holding the cords in a coiled shape for storage. For example, Deweese (U.S. Pat. No. 4,687,154), Brown (U.S. Pat. No. 4,586,675), Gaski (U.S. Pat. No. 4,277,035) and Vitale (U.S. Pat. No. 4,193,563) disclose devices for holding cords in a coiled shape for storage. In these prior devices, the cords remain on the holder devices until they are uncoiled therefrom for use.
- Other devices have been developed for manually winding a cord onto a storage reel. For example, Kovacik et al. (U.S. Pat. No. 6,186,433) discloses a cord storage unit having a spool and a winding knob rotatably mounted on a central hub. The cord remains on the spool during storage until the cord is unwound from the spool for use.
- These prior devices do not typically allow a user to place several electrical cords into coiled shapes for storage, while allowing the cords to be easily removed from the device for storage in a coiled shape separate from the device.
- There is a need for an improved device and method for winding electrical cords into a coil shape for storage.
- It is an object of the present invention to provide a device and method for winding electrical cords into a coil shape for storage, which allows the cords to be easily removed from the device and stored in a coiled shape separate from the device.
- It is a further object of the present invention to provide a device and method for winding electrical cords into a coil shape, which can be used to coil and store several different cords.
- It is a further object of the present invention to provide a device and method for winding electrical cords into a coil shape, which allows a cord wound thereon to be removed easily and nested into a compact coil shape for storage.
- It is a further object of the present invention to provide a device and method for winding electrical cords into a coil shape, which is economical to manufacture, easy to use, dependable in operation, and capable of a long operating life.
- To accomplish these and other objects of the present invention, a cord winder assembly for winding electrical extension cords is provided. The cord winder assembly includes a tapered drum attached to a generally horizontal shaft. A hand crank is attached to one end of the shaft, and the tapered drum is attached to the other end of the shaft. A stand with a base and two upright members is provided to rotatably support the shaft at spaced locations between the hand crank and the tapered drum. The tapered drum has first and second ends and an outer surface with a diameter that gradually decreases from the first end toward the second end. The tapered outer surface of the drum allows a cord wound thereon to be removed easily and nested into a compact coil shape for storage. A keyhole-shaped opening is provided in the outer surface of the tapered drum adjacent to the first end for receiving and holding a plug end of the electrical cord. An outer surface of the tapered drum is generally smooth and free of obstructions, and the shaft is supported in a cantilever fashion so that the electrical cord can be more easily removed from the second end of the tapered drum.
- According to one aspect of the present invention, a cord winder assembly is provided, comprising: a stand having at least one upright member; a generally horizontal shaft having a means for rotating the shaft attached to a first end, the shaft being rotatably supported by the upright member; and a tapered drum attached to the shaft and arranged to rotate with the shaft about a generally horizontal axis. The tapered drum has an opening in an outer surface thereof for receiving and holding an end of an electrical cord, and the tapered drum has first and second ends and a diameter that gradually decreases from the first end toward the second end to allow a cord wound thereon to be removed easily and nested into a compact coil shape for storage.
- According to another aspect of the present invention, a method of winding an electrical cord into a coil shape for storage is provided, comprising: providing a tapered drum supported to rotate about a generally horizontal axis, the tapered drum having an opening in an outer surface thereof for receiving and holding an end of the electrical cord, the tapered drum comprising first and second ends and having a diameter that gradually decreases from the first end toward the second end; inserting a plug end of the electrical cord into the opening in the outer surface of the tapered drum; rotating the tapered drum to cause the electrical cord to be wound onto the outer surface of the tapered drum; removing the plug end of the electrical cord from the opening in the outer surface of the tapered drum; and removing the electrical cord from the tapered drum by sliding the electrical cord over the second end, whereby the tapered shape of the drum allows the electrical cord to be removed easily and nested into a compact coil shape for storage.
- Numerous other objects of the present invention will be apparent to those skilled in this art from the following description wherein there is shown and described exemplary embodiments of the present invention. As will be realized, the invention is capable of other different embodiments, and its several details are capable of modification in various obvious aspects without departing from the invention. Accordingly, the drawings and description should be regarded as illustrative in nature and not restrictive.

cord winder assembly 10 for winding electrical cords according to the present invention will now be explained in detail with reference toFIGS. 1 to 7 of the accompanying drawings. - The
cord winder assembly 10 includes astand 11 having abase member 12, a firstupright member 13 extending upwardly from one end of thebase member 12, and a secondupright member 14 extending upwardly from another end of thebase member 12. The first and secondupright members openings 15 formed therein for receiving ahorizontal shaft 16 that extends through bothupright members upright members shaft 16 at two spaced apart locations to increase the stability of theshaft 16 during use. Atop brace 17 extends between the tops of the first and secondupright members stand 11. - The
horizontal shaft 16 has ahand crank 18 attached to afirst end 16 a thereof for rotating theshaft 16 during use. Thehand crank 18 has a connectingmember 19 attached to theshaft 16 and extending radially outwardly from theshaft 16. Ahand grip 20 is connected to an outer end of the connectingmember 19. Other means for rotating theshaft 16 could be used instead of the hand crank 18, such as a wheel or an electric motor attached to the shaft. - A tapered
drum 21 is attached to asecond end 16 b of theshaft 16. The tapereddrum 21 is arranged to rotate with theshaft 16 about a generally horizontal axis (i.e., the axis of rotation of the shaft 16) when the hand crank 18 is used to rotate theshaft 16. The tapereddrum 21 can be connected to theshaft 16 by havingrespective end walls 22 of thedrum 21 extend inwardly from anouter surface 23 of thedrum 21 and attached to theshaft 16 by asuitable coupling 24. - The
upright members stand 11 are both located between thedrum 21 and the hand crank 18 to support the intermediate portion of theshaft 16. Theshaft 16 extends past thesecond upright member 14 in a cantilever fashion with the tapereddrum 21 attached to the freesecond end 16 b of theshaft 16. This arrangement allows the tapereddrum 21 to be used without interference from additional supports near thesecond end 16 b of theshaft 16. - The tapered
drum 21 has afirst end 21 a and asecond end 21 b and a diameter that gradually decreases from thefirst end 21 a toward thesecond end 21 b. Theouter surface 23 of thedrum 21 is generally smooth and free of obstructions. The tapered shape of thedrum 21 allows a cord C to be wound onto thedrum 21 and then removed easily and nested into a compact coil shape for storage. - The tapered
drum 21 has anopening 25 formed in theouter surface 23 thereof near thefirst end 21 a of thedrum 21 for receiving and holding a plug end C1 of an electrical cord. Theopening 25 includes a keyhole-shaped opening having a firstlarge portion 25 a for inserting the plug end C1 of the electrical cord C therethrough, and a secondsmall portion 25 b adjacent to the firstlarge portion 25 a in a direction of rotation of thedrum 21. The secondsmall portion 25 b of theopening 25 is sized to accommodate the diameter of the electrical cord C, while preventing the plug end C1 from pulling back out. The opening 25 functions to maintain the plug end C1 within thedrum 21 while the electrical cord C is being wound onto thedrum 21. - The construction of the
cord winder assembly 10 of the present invention is explained above. A method of using thecord winder assembly 10 to wind an electrical cord C into a coil shape for storage will now be explained. - With the cord C in an extended condition, the plug end C1 of the cord C is inserted into the
opening 25 in theouter surface 23 of thedrum 21. Thehand crank 18 is then used to manually rotate thedrum 21 to cause the electrical cord C to be wound onto theouter surface 23 of thedrum 21. When the cord C is completely wound onto thedrum 21, the cord C can then be removed from thedrum 21 by sliding the cord C over thesecond end 21 b of thedrum 21 and removing the plug end C1 from theopening 25. The tapered shape of thedrum 21 allows the cord C to be removed easily and causes the cord C to be nested into a compact coil shape ideal for storage on awall hanger 26 or the like. - Since the cord C is completely removed from the
cord winder assembly 10 after it is wound into a coil shape for storage, thecord winder assembly 10 can then be used to wind another cord. This provides a significant advantage over other cord winders on the market that require the cord to remain on the spool for storage. Thecord winder assembly 10 of the present invention allows a user to wind several cords with a singlecord winder assembly 10, thereby making thecord winder assembly 10 very eco-friendly. - An alternative embodiment of the
cord winder assembly 10′ is illustrated inFIG. 7 . In this embodiment, aretainer plate 30 is removably attached to thesecond end 21 b of the tapereddrum 21. Theretainer plate 30 covers thesecond end 21 b of thedrum 21 and provides a lip at thesecond end 21 b for maintaining the electrical cord C on thedrum 21 during winding operations. Once the electrical cord C is wound onto thedrum 21, theretainer plate 30 can be easily removed by removing awing nut 31 or other suitable connector means that holds theretainer plate 30 against thesecond end 21 b of thedrum 21. With theretainer plate 30 removed, the electrical cord C wound on thedrum 21 can be removed by sliding the cord C off thesecond end 21 b of thedrum 21. - Another alternative embodiment of the
cord winder assembly 10″ is illustrated inFIG. 8 . In this embodiment, theretainer plate 30′ is removably attached to thesecond end 21 b of the tapereddrum 21 using a pair ofmagnets 32 fixed to the end of thedrum 21, and asteel plate 33 fixed to theretainer plate 30′. Thesecond end 16 b of theshaft 16 protrudes from thesecond end 21 b of thedrum 21 and mates with acentral opening 34 in theretainer plate 30′ to align theretainer plate 30′ with thedrum 21. The magnetic force between themagnets 32 and thesteel plate 33 holds theretainer plate 30′ against theend 21 b of thedrum 21 during cord winding operations, while allowing theretainer plate 30′ to be removed quickly and easily to allow a wound cord to be removed from thedrum 21. - While the invention has been specifically described in connection with specific embodiments thereof, it is to be understood that this is by way of illustration and not of limitation, and the scope of the appended claims should be construed as broadly as the prior art will permit.
