The present invention relates to a cord organizer. In particular the invention relates to device that stores and organizes power supply cords for portable electronic devices.
The National Electric Code (NEC) provides a classification system for power supplies. The following are relevant to the present invention.
Class 2. A Class 2 circuit is the portion of the wiring system between the load side of a Class 2 power source and the connected equipment.
Class II (with Roman numerals). A Class II circuit refers to power supplies with either a double or reinforced insulation barrier between the input and the output.
Due to its power limitations, a Class 2 or Class II circuit considers safety from a fire initiation standpoint and provides acceptable protection from electric shock. Most cell phone and mobile device chargers and laptop power supplies are Class II.
Class 1. A Class 1 circuit is connected to a power limited source but offers no protection from fire or electric shock. A Class 2 circuit offers the highest degree of protection.
Users of portable electronic typically struggle with cord management of the power supply cord. The cords are generally over 2 feet long and typically get tangled up with other cords or worse get snagged causing the device being charged to fall to the floor. The invention provides a solution to this common problem by providing a device that securely holds Class 2 and Class II, power supply cords for portable electronic devices such as mobile phones, mp3 players, hand held games, e-readers, tablets and other similar devices.
The prior art has described various cord holding devices. Representative of the prior art are the following patents.
U.S. Pat. No. 5,772,152 to Maldonado discloses a cord holder having an outer rotatable housing with an inner spool that rotates within a stationary hollow cord storage spool support. The spool fits into the housing in a telescopic manner.
U.S. Pat. No. 6,065,708 to Matsubara discloses a cord winder that includes a bottomed cylindrical shape and rotatable second component held in place therein. The rotatable component includes ribs formed on an outer surface of the cylindrical stud in a bobbin like structure. The device also includes a curved toothed braking structure.
U.S. Pat. No. 6,186,433 B1 to Kovacik et al. discloses a manually wound cord storage apparatus having a central hub, a handle and at least two feet attached to a planar body. The spool for storing an electrical cord is rotatably mounted on the central hub. A winding knob is mounted on the spool to assist in rotation of the spool around the central hub. The feet permit the apparatus to be used and stored in an upright position.
U.S. Pat. No. 6,554,218 B2 to Buyce et al. discloses a cable management spool for storing a length of cable including a spool and rigid members.
While spools are used in theses references, the prior art does not teach or suggest the invention device which includes two main parts, an outer shell and a rotatable spool that snaps snuggly into the inner part of the shell. The rotatable spool has one or two tracks which assist in securing the spool to the shell but also permits the spool to freely spin inside the shell. The tracks are located at either the inner top or bottom of the shell. The shell has a first entry hole big enough so that the power supply cord can fit thru.
To use the invention device, the portable power supply cord is lopped into the first entry hold of the outer shell leaving both ends of the cord free. The rotatable spool includes two or three flange of equal size. The spool has a centrally located second entry hole. The power supply cord after being looped into the shell is then looped into the second entry hole of the spool, still leaving both ends of the cord free. No hook or locking mechanism is necessary to hold the cord in place. Once the cord is looped onto the spool it is then snapped into the track of the shell. The rotatable spool is then manually wound to retract the cord into the invention device. When the cord is wound the power supply end of the cord is then inserted into the arbor of the spool. To retrieve the cord, all the user has to do is detach the power supply end from the arbor hole of the spool and pull out both ends of the cord to the desired length.
An advantage of the invention is in the provision of a solution to neatly and compactly store power cords for portable electronic devices.
Another advantage of the invention is in the provision of a solution to neatly and compactly store the power supply end for portable electronic devices.
Another object of the invention is to provide a compact device to improve ease of storage and use of power supply cords for portable electronic devices.
Yet another object of the invention is to provide convenient storage of power supply cords while allowing variable lengths to be deployed as desired.
Another object of the invention is in the provision of a compact device and related manual method to store and use power supply cords without the use of springs or any other mechanical elements, other than the rotatable spool.
Still another object of the invention is in the provision of a device that is not spring loaded, thus it does not have any mechanism that will break down.
Another object of the invention is in that the device can be used with the existing power supply that comes with electronic device.
In the present invention, these purposes, as well as others which will be apparent, are achieved generally by providing a device that stores and organizes a power supply cord for portable electronic devices.
The device comprises an outer shell 1 having a first entry hole 4; and an inner spool 2 having at least two circular flanges 6 connected in the middle by a barrel 8; a track 10 between the flanges; an arbor 7 on the top side and bottom side of the barrel; a second entry hole 5 within the device; and at least one tread 3 on the inner portion of said outer shell, wherein the spool fits snuggly into the outer shell to allow the spool to rotate therein.
At least one side of the arbor includes openings for the plug of the power supply cord to rest. In alternate embodiments, both sides of the arbor includes openings for the plug of the power supply cord to rest.
In the embodiment where there are two circular flanges the second entry hole 5 is on said barrel itself.
