## Background
FIELD OF THE INVENTION
This invention relates generally to the management of cords such as cords of the type that are attached to headphones, battery charging devices, and the like, and relates more particularly to a cord management device capable of receiving a portion of an accessory that is attached to the cord.
BACKGROUND OF THE INVENTION
The increasing popularity and availability of portable electronic devices has resulting in an increasing demand for cord management solutions for such portable electronic devices, which include MP3 and other music players, cell phones, personal digital assistants (PDAs), and the like. Left unmanaged, the various headphone cords, power cords, and other cords used by such portable electronic devices and the like tend to become tangled and disorganized, leading to an unsightly and potentially unsafe situation in which such cords can become, for example, caught on other objects, broken, or disengaged from the portable electronic device. Another cord management issue that arises with portable electronic devices is the management of the various hardware that is connected at the end of the cord, such as headphone ear buds, power cord connector tips, and the like. Accordingly, there exists a need for a cord management device that offers a simple and effective management solution for cords and their associated hardware.

DETAILED DESCRIPTION OF THE DRAWINGS
Portable music players, cell phones, and other portable electronic equipment have in recent years become almost ubiquitous. Many. such devices make use of headphones, recharging cables, microphones, and the like, many of which are connected to the portable electronic device by a cord or cords. In one embodiment of the invention, a cord management device comprises a body having a first end, a second end, a perimeter, and an interior bounded by the perimeter. The cord that is to be managed may be wrapped around the body of the cord management device in such a way as to control the length of the portion of the cord that is able to hang freely, thus protecting the entire cord. The cord management device further comprises an aperture spaced apart from the perimeter and extending through the interior of the body, the purpose of which will be further explained below, and still further comprises a recess in the interior of the body capable of receiving and storing an object attached to the cord.
Referring now to the figures, FIG. 1 is a perspective view of a cord management device 100, shown on an enlarged scale for clarity, according to an embodiment of the invention. As illustrated in FIG. 1, cord management device 100 comprises a body 110 having an end 111, an end 112 opposite end 111, a perimeter 113, and an interior 114 bounded by perimeter 113. More specifically, interior 114 comprises all of the surface area of body 110, including the surface area visible in FIG. 1 and also the surface area that is on a side of body 110 that is not visible in FIG. 1. As an example, cord management device 100 can be constructed of silicone or a similar material. In one embodiment, body 110 is solid, meaning there are no cavities therein. This excludes, of course, the various apertures and recesses that were introduced above and that are further described below.
Cord management device 100 further comprises an aperture 120 spaced apart from perimeter 113 and extending through interior 114 of body 110. As shown in a subsequent figure, and as further discussed below, aperture 120 is capable of receiving a portion of a cord or the like for the purpose of managing it using cord management device 100. In the illustrated embodiment, aperture 120 comprises a circular opening in interior 114 that extends into body 110. In a different embodiment, aperture 120 could have some other shape. In a particular embodiment, aperture 120 could simply be a terminal portion of a channel or slot such as a slot 130. In that particular embodiment, aperture 120 may or may not be enlarged beyond the width of such channel or slot.
In the embodiment illustrated in FIG. 1, aperture 120 is a first aperture of cord management device 100, and cord management device 100 further comprises an aperture 125, which is a second aperture of cord management device 100. Like aperture 120, aperture 125 is spaced apart from perimeter 113 and extends through interior 114 of body 110.
Slot 130, in the illustrated embodiment, extends between aperture 120 and perimeter 113. It may be said that aperture 120 communicates with slot 130 because slot 130 opens into aperture 120, as shown. Slot 130 is sized and positioned such that a portion of a cord may be introduced into slot 130 at perimeter 113 and slid along the length of slot 130 until the cord rests within aperture 120. Referring still to the illustrated embodiment, aperture 120 has a diameter 121, and slot 130 has a width 131, with diameter 121 being greater than width 131. The relative sizes just described make possible a potentially advantageous situation in which the cord to be managed, being only slightly smaller than width 131, passes with difficulty along slot 130 but moves freely through aperture 120. A potential advantage offered by such an arrangement is that the managed cord, which terminates in a hardware component larger than diameter 121, is unlikely to pass from aperture 120 through slot 130 unless deliberately caused to do so by a user of cord management device 100. The cord thus stays securely within aperture 120 until purposely removed. At the same time, the user is free to feed the managed cord through aperture 120 as needed or desired. In a different embodiment, aperture 120 is small enough to trap the managed cord such that it cannot move freely but instead must be pulled through aperture 120. One advantage offered by this different embodiment is that the managed cord may be easier to wrap around body 110 if the managed cord is constrained in the described manner.
In a non-illustrated embodiment, body 110 is lacking any slot analogous to slots 130 and 135. In that non-illustrated embodiment, aperture 120 must be large enough to admit the passage of any hardware component attached to an end of the managed cord. In order to admit the passage of such hardware component, yet still be capable of maintaining the managed cord within aperture 120 at all times that such is desired, the non-illustrated embodiment comprises a flexible membrane or the like within aperture 120 and having a sub-aperture with a sub-diameter smaller than the hardware component. The flexible membrane is sufficiently rigid so as admit the passage of the hardware component only with some difficulty, such that the hardware component is unlikely to pass through the flexible membrane unless caused to do so by a user of cord management device 100.
Cord management device 100 still further comprises a recess 140 in interior 114 of body 110. Recess 140, as will be shown in a subsequent figure, is capable of or suitable for receiving an object that is attached to an end of the cord that is being managed by cord management device 100. As an example, such object can be ear buds, earphones, or another portion of a headphone set, a connector tip for a power cord or a recharging cable, or the like.
In the illustrated embodiment, recess 140 forms a passageway that extends completely through body 110. In a non-illustrated embodiment, recess 140 could extend only partway through body 110. Also in the illustrated embodiment, recess 140 is a first recess of cord management device 100, and cord management device 100 further comprises a recess 150, which is a second recess in interior 114 of body 110. Having two such recesses as illustrated in FIG. 1 may be advantageous for managing headphone cords and the like where the object at an end of the cord comprises, for example, two separate ear buds or the like, each of which can be received by one of recesses 140 and 150, as will be further illustrated in a subsequent figure.
As an example, recess 140 and recess 150 can be spaced apart from each other, as illustrated, and a portion of interior 114 forms a bridge 145 that stretches between recess 140 and recess 150. As another example, aperture 120 can be adjacent to recess 140, and aperture 125 can be adjacent to recess 150, as shown.
Also in the illustrated embodiment, body 110 comprises a slot 135, which can be similar to slot 130, associated with aperture 125. Aperture 120, recess 140, and slot 130 are located at end 111 of body 110, while aperture 125, recess 150, and slot 135 are located at end 112 of body 110.
Still referring to FIG. 1, body 110 of cord management device 100 further comprises a middle portion 117 located between end 111 and end 112. Middle portion 117 is narrower than ends 111 and 112, giving cord management device 100, in the illustrated embodiment, an hourglass or figure-eight shape. Notwithstanding the illustration, the result of a narrow middle portion like that just described is could also be any of a number of shapes characterized generally by opposing end portions that are broader or wider than a middle portion located between the end portions. It should be understood that the narrowing can occur in any of the three dimensions or axes of cord management device 100. This mention of such axes is the first that occurs herein; the axes are fully introduced in the following paragraph.
Body 110 has a first axis 170, a second axis 180 that is perpendicular to first axis 170, and a third axis 190 that is perpendicular to both first axis 170 and second axis 180. First axis 170 is a long axis of body 110, and a length of body 110 is measured along or parallel to first axis 170. A width and a thickness of body 110 are measured, respectively, along or parallel to second axis 180 and third axis 190. As an example, body 10 has a thickness 191.
In the illustrated embodiment, recesses 140 and 150 and apertures 120 and 125 all lie substantially on first axis 170. In a different embodiment, at least one of recesses 140 and 150 and apertures 120 and 125 can be located off first axis 170. In the same or another embodiment, body 110 is symmetric about first axis 170, about second axis 180, or both. Such symmetry may or may not extend to the placement of apertures 120 and 125 and/or slots 130 and 135.
FIG. 2 is a perspective view of a cord management system 200 according to an embodiment of the invention. As illustrated in FIG. 2, one of the components of cord management system 200 is cord management device 100 that was first shown in FIG. 1. In addition, cord management system 200 comprises an object (not shown in FIG. 2) such as headphone ear buds or the like. The other end of cord 210, in the illustrated embodiment, terminates in a connector tip 220 that may be coupled to an MP3 player or other music player, a cell phone, a PDA, or the like. As suggested and partially shown by FIG. 2, middle portion 117 is capable of supporting cord 210 as cord 210 is wrapped on or around cord management device 100.
FIG. 2 also shows a portion of cord 210 in aperture 125, cord 210 having been placed therein, for example, in a manner such as was described above. With the portion of cord 210 in aperture 125, a different portion of cord 210 may easily be wrapped about middle portion 117 or a different section of cord management device 100. FIG. 2 depicts cord 210 after it has been passed a first time around middle portion 117.
FIG. 3 is a perspective view of cord management system 200 after cord 210 has been passed several times around middle portion 117 according to an embodiment of the invention. Like FIG. 2, FIG. 3 depicts a portion of cord 210 in aperture 125. In addition, FIG. 3 depicts a different portion of cord 210 in aperture 120. With portions of cord 210 in apertures 102 and 125 and wrapped about middle portion 117, cord 210 is securely held on cord management device 100 in such a way as to be unlikely to get tangled or broken or to get caught on other objects.
A section 211 of cord 210 is not wrapped around middle portion 117 or located within aperture 120, but instead extends beyond end 111 of cord management device 100 and terminates at connector tip 220. Similarly, a section 212 of cord 210 extends beyond end 112 of cord management device 100 and terminates at an object that is not shown in FIG. 3 but that is shown in FIG. 4, described below.
The number of times cord 210 is wrapped around middle portion 117 depends on the desired lengths of sections 211 and 212, which were indicated above to be opposing free, unwrapped ends of cord 210. If longer free ends are desired, cord 210 is wrapped fewer times, while if shorter free ends are desired, cord 210 is wrapped a greater number of times. The greater width of ends 111 and 112 as compared to the width of middle portion 117 tends to keep the wrapped portion of cord 210 in place on cord management device 100.
FIG. 4 is another perspective view of cord management system 200 according to an embodiment of the invention. The object referred to above as being located at an end of cord 210 is illustrated in FIG. 4 as an object 410. It was mentioned above that recesses 140 and 150 (see FIGS. 1-3) are capable of receiving a portion of object 410. FIG. 4 shows that portions of object 410, which in the illustrated embodiment comprises a pair of ear buds, are located within recesses 140 and 150. Thickness 191 of body 110 (see FIG. 1) is, in one embodiment, at least as great as the thickness of object 410.
As an example, a shape of recesses 140 and 150 can be complementary to a shape of object 410, and recesses 140 and 150 can be sized so as to form a friction fit with object 410. Object 410 thus fits snugly within recesses 140 and 150, and tends to stay in place until deliberately removed. As shown, when object 410 is stored in recesses 140 and 150, cord 210 may be removed from aperture 125.
