## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This non-provisional patent application claims priority from U.S. Patent Application Ser. No. 60/878,874, filed Jan. 5, 2007, and U.S. patent application Ser. No. 11/127,336, filed on May 11, 2005, and both applications are hereby incorporated by reference.


TECHNICAL FIELD
This disclosure relates generally to grommets and more particularly to grommets having electronic components.
BACKGROUND
The management of various cables, cords, and wires found on a typical work surface is an ongoing challenge. Almost all of the increasing number of available devices, including telephones, computers and their many peripheral devices, digital cameras, personal digital assistants (PDAs), and so forth, use at least one and often multiple cables to transfer data, receive power, and/or perform other functions. Without some sort of management system, the number of cables on a desktop can quickly become a tangled mess that is both unsightly and unwieldy.
The increase in the number of peripheral and other devices has led to the introduction of connection hubs, which are units having multiple connection ports contained in a single housing. Accordingly, there exists a need for a connectivity system that both increases the available connection options on a desktop and also improves cable management.

The design and the manufacturing process for USB hubs and other electrical components are well-know in the art and will not be described in detail herein. Among some exemplary embodiments, electrical components 130 comprise a power indicator 139 capable of illumination or otherwise alerting a user when electrical components 130 are receiving power through one or more of electrical connectors 131.
Continuing with the exemplary embodiment of FIG. 1, electrical device 100 can comprise electrical conductors 138 that comprise wires, conductive material deposited on a semiconductor device or on a printed circuit board, or any other type of material capable of electrically coupling electrical components 130 to electrical connectors 131. As described herein “conductors” can refer to a single conductor, or two or more conductors, depending on the number of conductors used to electrically couple electrical components 130 to electrical connectors 131.
In an exemplary embodiment, electrical connectors 131 comprise six electrical connectors, 132, 133, 134, 135, 136, and 137. In this illustrated exemplary embodiment, three electrical connectors 132, 133, and 134 can be located at a first side of electrical components 130, and three electrical connectors 135, 136, and 137 can be located at a second side of electrical components 130. In this exemplary embodiment shown, the second side is opposite the first side. Among various other exemplary embodiments, though, any configuration with respect to quantity and position of electrical components and/or electrical connectors is contemplated by the present invention.
Among various exemplary embodiments, electrical connectors 131 comprise one or more USB connectors, and in some exemplary embodiments comprise at least one power connector. In one example, an electrical connector comprises a power connector 135, and electrical connectors 132, 133, 134, 136, and 137 comprise USB type connectors. In another exemplary embodiment, electrical connectors 131 comprises a power connector 135, electrical connectors 132, 133, 134, and 137 comprise USB type-A connectors, and electrical connector 136 comprises a USB type-B connector. In yet other exemplary embodiments, electrical connectors 131 comprise other types of USB connectors. In still yet another exemplary embodiment, electrical connectors 131 can comprise serial, parallel, FireWire, and any other type of electrical connectors.
As shown by the exemplary embodiment in FIG. 1, two or more of electrical connectors 132, 133, and 134 can be parallel to each other, as represented by apertures 112, 113, and 114, and electrical connector 136 can be perpendicular to electrical connector 137, as represented by apertures 147 and 148. Among various other exemplary embodiments, electrical connectors and apertures can comprise various other types of positioning. The electrical connectors and apertures can be parallel or perpendicular to another connector and aperture. The various electrical connectors and apertures can also be, at an angle, positioned above, positioned below, adjacent, opposite, in series, and any other like configuration. Moreover, those skilled in the art can appreciate that electrical connectors 131 are capable of electrically coupling electrical device 100 to one or more foreign electrical devices, components, or systems, and the electrical devices can be similar to or different from electrical device 100.
Still continuing with reference to the exemplary embodiment of FIG. 1, casing 105 comprises: a grommet 110 comprising one or more apertures 111; a gasket 120; a screen 140; and a connection mechanism 150 that can be coupled to grommet 110. Among some embodiments, screen 140 can be part of connection mechanism 150, but among other exemplary embodiments screen 140 can be part of grommet 110. In an exemplary embodiment, grommet 110 can comprise: flange 115; apertures 111; and insertion portion 117 that comprises a coupling mechanism 118. In one example, and as briefly mentioned above, insertion portion 117 comprises a diameter less than the diameter of grommet hole 504 (FIG. 5) to allow insertion of insertion portion 117 into grommet hole 504 (FIG. 5). In one embodiment, grommet hole 504 (FIG. 5) comprises a diameter in the range from about two to about three inches (approximately 5.1 to 7.6 centimeters), and the insertion region comprises a diameter slightly less than two inches (5.1 centimeters). In this embodiment, flange 115 is proximate to side 306 (FIG. 4) when insertion portion 117 is inserted into grommet hole 504 (FIG. 5). In this same embodiment, flange 115 comprises a diameter of about 3.4 inches (8.6 centimeters).
With reference to the exemplary embodiment described so far, apertures 111 can comprise apertures 112, 113, 114, 121, 122, and 123. In one embodiment, electrical connectors 132, 133, and 134 are accessible through and/or protrude from apertures 112, 113, and 114, respectively. In such an example, power indicator 139 can be visible through aperture 121. Moreover, apertures 122 and 123 provide conduits within casing 105 by which electrical cables (not shown) can pass through flange 115 when insertion portion 117 is inserted into grommet hole 504 (FIG. 5).
Among some exemplary embodiments, electrical device 100 comprises gasket 120. Gasket 120 can help deter unwanted movement of electrical device 100. Gasket 120 can be a circular ring having inner and outer diameters larger than the outer diameter of insertion portion 117 but smaller than the diameter of flange 115. In one embodiment, before inserting insertion portion 117 into grommet hole 504 (FIG. 5), gasket 120 is placed around insertion portion 117 such that gasket 120 is proximate the bottom of flange 115. In this embodiment, when insertion portion 117 is inserted into grommet hole 504 (FIG. 5), flange 115 abuts gasket 120, and gasket 120 abuts side 306, as shown in FIG. 4. In one exemplary embodiment, gasket 120 can be manufactured from a flexible, compressible material with high friction surfaces. For example, gasket 120 can be made from rubber or a soft, high friction surface plastic.
In the exemplary embodiments described herein, screen 140 can couple to electrical components 130 and electrical connectors 135, 136, and 137 to provide protection for electrical components 130 and electrical connectors 135, 136, and 137. In one embodiment, electrical connectors 135, 136, and 137 are accessible through or protrude from apertures 146, 147, and 148 in screen 140. In the same or a different embodiment, screen 140 can be coupled to insertion portion 117 to secure electrical connectors 131, electrical conductors 138, and electrical components 130 within casing 105. In one exemplary embodiment, screen 140 comprises two snaps 141 that can couple to mating holes (not shown) on the inside surface of insertion portion 117. Although, one exemplary embodiment describes snaps and mating holes, other securing devices to secure screen 140 to insertion portion 117 can be used.
Among the various exemplary embodiments described herein, in one example, connection mechanism 150 comprises at least one aperture 160, and connection mechanism 150 can comprise: a flange 155 with one or more optional springs 156; and a body portion 157 with a coupling mechanism 158. In one embodiment, electrical connectors 135, 136, and 137 are accessible through or protrude from aperture 160 at side 407 of table 305 (FIG. 4). In one embodiment, the interior diameter of aperture 160 is larger than the exterior diameter of insertion portion 117 to allow a portion of insertion portion 117 to insert into aperture 160. Furthermore, flange 155 comprises an outer diameter larger than the diameter of grommet hole 504 (FIG. 5) to prevent connection mechanism 150 from receding into grommet hole 504 (FIG. 5). In one example, flange 115 comprises a diameter of about 3.4 inches (8.6 centimeters).
In one exemplary embodiment of the present invention, insertion portion 117 can be positioned within grommet hole 504 (FIG. 5). When insertion portion 117 is inside grommet hole 504 (FIG. 5), grommet 110 can be coupled to connection mechanism 150 proximate to side 407. FIG. 2 illustrates an example of electrical device 100 after grommet 110 has been coupled to connection mechanism 150. In one embodiment, grommet 110 can be coupled to connection mechanism 150 by engaging coupling mechanism 118 with coupling mechanism 158.
In the illustrated exemplary embodiment of FIGS. 1-4, coupling mechanism 118 comprises two or more substantially horizontal grooves 119 and a vertical groove 125. Coupling mechanism 158 can comprise at least one protrusion 159. To engage coupling mechanism 118 with coupling mechanism 158, insertion portion 117 is inserted into aperture 160. When protrusion 159 aligns with vertical groove 125, grommet 110 and connection mechanism 150 can collapse toward each other until connection mechanism 150 is proximate side 407, and grommet 110 or gasket 120 is proximate side 306. If when insertion portion 117 is inserted into aperture 160 and protrusion 159 does not align with vertical groove 125, then coupling mechanism 118 and coupling mechanism 158 cannot engage one another, and grommet 110 and connection mechanism 150 can be rotated relative to one another until protrusion 159 and vertical groove 125 are aligned. Once protrusion 159 aligns with vertical groove 125, and grommet 110 and connection mechanism 150 collapse toward each other as described above, connection mechanism 150 can be rotated in a first circular direction in relation to grommet 110 to engage protrusion 159 with horizontal groove 119. For example, protrusion 159 slides into one of horizontal grooves 119. In one embodiment, the first circular direction is clockwise, however, other exemplary embodiments can comprise a configuration where the circular direction is counter-clockwise.
In the exemplary embodiment described above, coupling mechanism 118 and the corresponding groove structure is illustrated as part of insertion portion 117, and coupling mechanism 158 comprising protrusion 159 is illustrated as part, of connection mechanism 150. In other exemplary embodiments, though, the reverse configuration is contemplated by the present invention, that is, connection mechanism 150 can comprise the groove structure, and insertion portion 117 can comprise the protrusion. Any other groove and protrusion configurations are similarly contemplated by this disclosure, as well, as any other engaging mechanisms that can function to secure grommet 110 to connection mechanism 150.
Continuing with the exemplary embodiment as illustrated in FIG. 1, by engaging protrusion 159 with one of horizontal grooves 119, grommet 110 effectively locks to connection mechanism 150. In some examples, horizontal grooves 119 further comprise small tabs to help hold protrusion 159 in one of horizontal grooves 119. While the exemplary embodiment described herein discusses protrusion 159 engaged with horizontal grooves 119 to secure the position of grommet 110 with connection mechanism 150, any other type of securing mechanism that can secure grommet 110 with connection mechanism 150 is contemplated by this disclosure. For example, hooks, tabs, glues, screws, pins, springs, cavities, ties, snaps, and the like are contemplated by this disclosure.
In some exemplary embodiments, gasket 120 and springs 156 can be used to provide a more stable and a tighter coupling of grommet 110 to connection mechanism 150. The compressibility of gasket 120 and springs 156 help align protrusion 159 with one of horizontal grooves 119 by providing flexibility to where gasket 120 and connection mechanism 150 abut sides 306 and 407 (FIG. 4), respectively. Springs 156 as described herein can be cantilevered arm type springs, however, any other type of spring, such as coiled, toroid, and the like are contemplated by this disclosure.
In an exemplary embodiment, when insertion portion 117 resides within grommet hole 504 (FIG. 5) and grommet 110 is coupled to connection mechanism a first one of electrical connectors 132, 133, and 134 are accessible through apertures 111 at side 306.
Among the various exemplary embodiments described herein, casing 105 can be preferably made of a material that is tough, hard, and rigid, has good chemical resistance and dimensional stability, exhibits good creep resistance, and is relatively strong and inexpensive. Accordingly, casing 105 can be constructed of acrylonitrile butadiene styrene (ABS), polycarbonate, polypropylene, polyethylene, or a similar material, all of which, to varying degrees, exhibit the stated properties. In one embodiment, casing 105 is made using an injection molding process, however, other molding processes can be used. Injection molding processes for creating plastic casings are well-known in the art and will not be described herein.
Turning now to FIG. 6, FIG. 6 illustrates an exploded view of an electrical device 600, according to a second embodiment. In this embodiment, casing 605 does not include a gasket or springs. Top portion 617 comprises a coupling mechanism 618 and connection mechanism 650 comprises a coupling mechanism 658.
In the embodiment shown in FIG. 6, coupling mechanism 618 comprises two or more partially threaded regions 680 separated by non-threaded regions 681. In one example, the diameter of partially threaded regions 680 is larger than the diameter of the non-threaded regions 681. In some embodiments, the diameter of partially threaded regions 680 is larger than the diameter of non-threaded regions 681 by the thickness of the threads in partially threaded regions 680. Coupling mechanism 658 of connection mechanism 650 can comprise a full thread 682. In this embodiment, coupling mechanism 618 couples to coupling mechanism 658 by coupling partially threaded regions 680 to full thread 682 in a screw-like manner. The exemplary electrical device 600 can be used with or without a gasket. In another embodiment, coupling mechanism 618 can comprise full threads, and coupling mechanism 658 can comprise partial threads. In a further embodiment, coupling mechanisms 618 and 658 can comprise the same type of threads.
It can be appreciated by those skilled in the art that the exemplary embodiment shown in FIG. 6 can also comprise other features described herein of the embodiment shown in FIG. 1. For example, electrical device 600 can comprise electrical components similar to the electrical components 130 of electrical device 100. Electrical device 600 can further comprise electrical connectors, a power indicator, and electrical conductors similar to electrical connectors 131, power indicator 139, and electrical conductors 138 of electrical device 100. The other elements described with respect to electrical device 100 can be incorporated into electrical device 600, as well as other exemplary embodiments contemplated by this disclosure.
In an exemplary embodiment, FIG. 7 illustrates electrical device 100 configured for use with table 370 having a first thickness 790, and FIG. 8 illustrates electrical device 100 configured for use with a table 870 having a second thickness 890.

Electrical device 600 can also be used with tables 370 and 870, and electrical device 100 can also be used with tables 970 and 1070.
In an alternate embodiment of an electrical device, FIG. 11 illustrates electrical device 1100 comprising a grommet 1110 comprising an aperture 1160, and a connection mechanism 1150 comprising an insertion portion 1117. This exemplary embodiment can be an opposite configuration of exemplary embodiment 100 described hereinabove. Instead of the grommet comprising an insertion portion that inserts into a grommet hole from a first side, this embodiment contemplates the insertion portion as part of the connection mechanism, and the connection mechanism couples with the grommet by inserting the insertion portion into a grommet hole from a first side. In this exemplary embodiment, grommet 1110 still comprises a flange 1115 similar to flange 115 of grommet 100, and flange 1115 functions correspondingly to cover the perimeter of a grommet hole 1104 in a table 1170. This exemplary embodiment further comprises electrical connectors 1131 similar to electrical connectors 131 of electrical device 100. Other elements described herein with respect to other electrical device embodiments are likewise contemplated for this exemplary embodiment. For example, electrical device 1100 can also have apertures similar to apertures 122 and 123 in electrical device 100 in FIG. 1.
Among the various electrical devices described herein, the electrical devices have been shown comprising a circular configuration to accommodate a circular grommet hole. The present invention, though, contemplates, other shape or decorative configurations to accommodate other grommet hole configurations. For example, electrical devices and grommet holes comprising square, octagonal, oval, hexagonal, and any other regular or irregular shape configuration are likewise contemplated by this disclosure.
Among the various electrical devices described herein, the electrical devices are configured for use with any table or like structure that comprises an aperture or grommet hole for the various exemplary electrical devices described herein to fit or couple within. For example, other structures such as a desk, bench, shelf, and the like are contemplated by this disclosure. Moreover, the thickness of any table or like structure can vary to any degree that will allow the electrical device to be used as described.
Turning now to an exemplary method for using an electrical device, and as outlined in the flow chart of FIG. 12, the method 1200 comprises: providing a grommet comprising one or more first apertures, one or more electrical components accessible through the one or more apertures, and an insertion portion (a block 1210); providing a connection mechanism (a block 1220); inserting the insertion portion into a grommet hole such that a portion of the grommet remains at a first side of the grommet hole (a block 1230); coupling the connection mechanism to the insertion portion when the connection mechanism is located at a second side of the grommet hole opposite the first side (a block 1240); and coupling a first device to the one or more electrical components through the one or more apertures (a block 1250). Among various embodiments, when the connection mechanism couples to the insertion portion (block 1240) in the grommet hole, a distance between a flange of the connection mechanism and a flange of the grommet is substantially similar to a depth of the grommet hole. Further more, when coupling the connection mechanism to the insertion portion (block 1240), the method can comprise engaging a locking mechanism to secure the insertion portion to the connection mechanism, and when engaging the locking mechanism, the engaging can comprise aligning a protrusion at an interior portion of the connection mechanism with a groove at an exterior portion of the insertion portion; and rotating one of the connection mechanism or the insertion portion relative to the other one of the connection mechanism and the insertion portion such that the protrusion is positioned within the groove.
Among the various method of use embodiments, when coupling the first device (block 1250), the first device can couple to the one or more components through the one or more apertures at the first side of the grommet hole. In an alternate embodiment, the first device couples to the one or more components through the one or more apertures at the second side of the grommet hole. In still yet another embodiment, the method 1200 comprises coupling a second device to one or more components through a second one of the one or more apertures at the first side of the grommet hole.
In an exemplary embodiment of the present invention, a method 1300 for manufacturing an electrical device comprises: providing a casing (a block 1310), wherein providing the casing comprises providing a grommet comprising one or more first apertures and an insertion portion (a block 1312), and providing a connection mechanism configured to couple to the grommet (a block 13114).
