## Title
Cord management sleeve

## Abstract

The cord management sleeve is used to retain an electric cord that is bent in several segments in a bow-tie-like arrangement. The cord management sleeve has a first and second halves, each having a cylindrical shape. The first half is coaxially engaged into the second half, for rotation into the second half. The first half has a circumferential ridge on an end thereof. The second half has a circumferential groove on an end thereof. The circumferential ridge is engaged into the circumferential groove with a sliding fit. Each of the halves has a longitudinal slot therein, and these longitudinal slots are movable relative to each other by rotation of the halves relative to each other, for selectively aligning the slots or setting off an alignment of the slots. The segments of a cord are inserted though the slots and kept in the sleeve by setting off the alignment of the slots.

## Background
FIELD OF THE INVENTION
This invention pertains to cord management devices, and more particularly it pertains to devices for use on electric extension cords, computer cables, and cords on appliances and tools, for retaining these cords in a compact and organized arrangement.
BACKGROUND OF THE INVENTION
The disorderly layout of computer cables for example is a sore sight for many people. Stereo and television systems are also encumbered with intertwined cords wherein it is difficult to find out which cord belongs to which module. The same can be said for battery chargers of laptop computers, portable telephones and personal sound systems; for cords of earphones, UBS ports, and for cords of tools and toys of all kind.
Numerous efforts have been made in the past to develop cord management devices. An exceptionally large quantity of cord management devices has been found in the prior art. These devices are illustrated and described in the following documents:

It is believed that a large portion of the cord management devices found in the prior art did not enjoy a lasting commercial success. Such a low market response to these devices can be attributed to several factors, including complexity, adaptability, appearance and the level of skill required to use them.
It is believed that there is a market need for a cord management device that has a simple construction, that can be understood at a first glance, and that can be used with minimum instruction.
SUMMARY OF THE INVENTION
In the present invention, there is provided a cord management sleeve that is made of two parts with a slot in each part. The slots are aligned with each other to insert segments of a cord in the sleeve. The alignment of the slots is set off for holding the segments of the cord inside the sleeve, so that the cord is held in a compact and orderly manner, in a bow-tie-like arrangement. The segments can then be aligned and pulled along to form loops of equal length so that the bundled cord has a neat and organized appearance.
In a first aspect of the present invention, there is provided a cord management sleeve that has a first and second halves, each having a hollow cylindrical shape. The first half is coaxially engaged into the second half, for rotation into the second half about a common axis. The first half has a circumferential ridge on an end thereof. The second half has a circumferential groove on an end thereof. The circumferential ridge is engaged into the circumferential groove with a sliding fit so that both halves are held to each other end-to-end. Each of the halves has a longitudinal slot therein, and these longitudinal slots are movable relative to each other by rotation of one half relative to the other, for selectively aligning the slots or setting off an alignment of the slots.
This cord management sleeve is easy to understand at a glance so that commercialization can be made with minimum instruction. This cord management sleeve is also easy to use for retaining cords of all sizes and types.
In another aspect of the present invention, there is provided a cord management sleeve wherein the first half is coaxially engaged into the second half without interlocking joint, for rotation into the second half. Each half has a longitudinal slot therein, as in the aforesaid embodiment. This cord management sleeve is easier to manufacture that the first-mentioned embodiment.
This brief summary has been provided so that the nature of the invention may be understood quickly. A more complete understanding of the invention can be obtained by reference to the following detailed description of the preferred embodiments thereof in connection with the attached drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to the drawings in FIGS. 1, 2 and 3, the first preferred embodiment of the present invention will be described. The first preferred embodiment of the cord management sleeve 20 is comprised of two hollow cylindrical halves 22, 24 having a same inside diameter. The first half 22 and a circumferential ridge 26 on the end thereof. The other half 24 has a circumferential groove 28 in one end thereof, and the groove 28 has location and dimensions to receive the ridge 26 therein in such a way as to retain both halves 22, 24 together while allowing a rotational movement of each half relative to the other. The groove 28 has shape and dimensions to receive the circumferential ridge 26 therein with a free sliding fit.
The location and dimensions of the ridge 26 and groove 28 are such that when both halves 22, 24 are interlocked with each other, the joint between the halves forms a single circumferential line 30 on the outside surface of the sleeve 20, as shown in FIGS. 2 and 3.
Both halves 22, 24 have a respective longitudinal slot therein. These slots are labelled 32 and 34 respectively. As can be understood, these slots 32, 34 extend throughout the shell of the sleeve 20. These slots 32, 34 have a width to accommodate the thickness of a cord to be inserted in the sleeve 20. When both slots 32, 34 are aligned with each other such as shown in FIG. 3, an electric cord can be inserted in the sleeve 20 one or several segments at the time.
The first preferred cord management sleeve 20 can be made of wood, plastic or metal, according to the choice of the designer and the intended application. A sleeve made of wood for example, can be stained to match the furniture in the room where the sleeve will be used, to enhance the decor of the room.
The exterior appearance of the sleeve according to the first preferred embodiment is a fat look, with a slightly convex side and rounded ends. It is believed that this shape has better visual appeal than the straight tubing shape in the other preferred embodiments presented herein. Other shapes may also be used according to the choice of the designer.
The preferred sleeve 20 is made of a material that has resilience, such that the half 22 with the ridge 26 can be squeezed slightly and inserted in the groove 28 in the other half 24 wherein it expands and remains locked to the other half 24.
Referring now to FIG. 2, the cord 40 is preferably bent in equal segments 42 and inserted one segment at the time into the sleeve 20. The halves 22, 24 are then rotated to set off the alignment of the slots 32, 34 to keep the cord segments 42 captive inside the sleeve, and to maintain the cord 40 in a neat and tidy configuration, as shown in FIG. 2. The segments 42 can be pulled along the axis of the sleeve 20 to form loops of a same length.
Different sleeve sizes are used for different cord sizes and lengths. For example, a first embodiment of the preferred sleeve 20 with a one inch inside diameter can hold 12 strands of a 16-2 AWG extension cord. Similarly, a half-inch inside diameter sleeve can hold 12 strands of a 22-2 AWG cord, such as the cord of a battery charger for a cell phone for example.
When the cord is needed, the slots 32, 34 are realigned and one or more segments 42 are taken out of the sleeve 20 to make up for the length of cord needed. The slots 32, 34 are set off alignment again to hold the remaining segments inside the sleeve 20.
Referring to FIG. 4, the inside diameter of the preferred sleeve 20 needs not be a perfect circle. The inside openings in the halves 22,24 can be oval for example as shown at label 50, with the longer axis of the ellipses aligning with its respective slots 32, 34. When the two halves 22, 24 are rotated relative to each other, the inside opening 52 of the combined halves of the sleeve 20 is much smaller than the ellipse 50, providing a tightening action on the remaining segments inside the sleeve 20.
The elliptical shape of the openings 50 through the sleeve 20 is optional. It has been found that the first preferred cord management sleeve 20 with a circular opening works just as good with 4 strands therein as it does with 12 strands. An electrical cord has a certain degree of resilience, and when the cord 40 is bent and inserted in the sleeve, the resiliency of the cord keeps the segments 42 in frictional contact with the inside surface of the sleeve 20. In fact, the preferred sleeve 20 needs not to be packed full to work as expected.
Referring now to FIG. 5, the second preferred embodiment of the cord management sleeve according to the present invention will be explained.
In this second embodiment, the sleeve 60 can be made of metal tubing and the joint 62 between the halves 64, 66 can be a preformed joint made by common tube expander tools, such as those used for flaring tube ends.
The overlap “A” between the halves 64, 66 can be any length, as long as both halves are accessible for rotation by finger-grip strength. When this overlap “A” is sufficiently long, such as half the length of one of the halves 64, 66, there is no need for the preformed joint 62. In that context, the third and fourth embodiments 80, 82 illustrated in FIGS. 7 and 8 respectively, with one half partially or entirely overlapping the other, are satisfactorily for obtaining the desired results with smaller sizes of electrical cords, for example.
Coming back to FIG. 6, the slots 68, 70 in the cord management sleeve 60′ can be straight or curved such as in a helix-like form for example. Although a sleeve 60 with helix-like slots might be better to retain all the segments of a cord therein, this type of slot might be more difficult to understand by the general public.
FIG. 9 shows a variant 84 of the fourth preferred embodiment 82, wherein the outer half 86 is held centred over the inner half 88 by a pair of raised shoulders 90 on the surface of the inner half 88.
As to further construction details, and other method of use of the cord management sleeve according to the preferred embodiments of the present invention, these details should be apparent to those skilled in the art, and accordingly, further description relative to these aspects is deemed unnecessary.
