BACKGROUND OF THE INVENTION
1. Technical Field
The invention disclosed herein relates to electrical outlet covers.
2. Related Art
Electrical devices used in conjunction with electrical device boxes vary and include electrical outlets (both standard and ground fault current interrupts), light switches (both toggle and rocker plates), rounds, and cable television and/or telephone ports. Conventional covers for electrical device boxes are designed to try and prevent inadvertent access to the electrical conductive elements of electrical devices and to hide associated wiring. Each type of electrical device requires different dimensioned access openings in a cover to accommodate it. However, conventional covers usually are non-convertible in their design, and therefore, each electrical device requires a different type of conventional cover configured for it. Thus, to install or service electrical devices, an electrician must carry several types of conventional covers to each site, which are time consuming and inefficient to install.
SUMMARY
According to one aspect of the disclosure, an electrical outlet cover assembly may be implemented with a base, the base further comprising a planar member wherein the planar member further comprises a substantially rectangular mounting aperture and at least one detachable adapter. The detachable adapter can be configured to form part of a first aperture by mounting the at least one detachable adapter to the rectangular mounting aperture on the base, and wherein the first aperture is substantially circular and configured to receive an electrical socket.
Such assembly can be further configured with a first aperture that is configured to function as a mounting space for receiving a second detachable adapter and wherein said second detachable adapter is configured to form a second aperture for receiving a second electrical socket of smaller diameter. The second aperture on the second detachable adapter can function again as a second mounting space by mounting a third adapter configured to fit the second aperture and wherein said third aperture is configured to receive a third electrical device such as a third electrical socket or toggle switch.
The third aperture can function as mounting space to receive a fourth or fifth, recursively, detachable adapter so as to form a fourth or fifth, recursively, aperture for receiving an electrical device of smaller area, and so on and so forth.
In another embodiment, the planar member on the base further comprises a substantially rectangular mounting aperture.
In the same vain, one or more additional detachable adapters can be included. Wherein the one or more additional detachable adapters are configured to form one or more additional apertures by mounting the one or more detachable adapters to the mounting aperture on the base.
The one or more additional apertures is configured to receive an electrical duplex socket or a ground-fault circuit interrupt (GFCI) socket. In fact, it is the purpose of the invention to be as inclusive as possible. As such, many other configurations are possible. For example, any one of the apertures disclosed herein, infra or supra, can be configured to fit any number of devices, electrical or not, and including
By way of non-limiting example, at least one detachable adapter has two notches equally spaced around the first aperture and wherein the second detachable adapter and fifth detachable adapter both have two equally spaced tabs protruding circumferentially outward.

The spirit of this invention contemplates, by way of non-limiting example, a second detachable adapter that can have two notches equally spaced around the second aperture, and even a third detachable adapter and the forth detachable adapter both can have two equally spaced tabs protruding circumferentially outward. The two equally spaced notches on the second detachable adapter are shaped to fit to the two equally spaced protruding tabs on the third detachable adapter or on the forth detachable adapter so as to orientate and secure the third detachable adapter to the second detachable adapter to form the third aperture or to orientate and secure the forth detachable adapter to the second detachable adapter to form the forth aperture.
In yet another implementation of the invention, any one or more of the at least one detachable adapters can have, for example, two or more equally spaced tongue-like clips around an aperture. The two equally spaced tongue-like clips can themselves be circumferentially and inwardly protruding so as to snap on to a device such as an electrical round socket, electrical toggle switch, or other electrical or non-electrical fitting as would be readily apparent to one of ordinary skill in the art.
In yet another embodiment of the invention disclosed herein, we have a base, the base further comprising a planar member, four sides and a hinge, and wherein the base comprises a single molded piece, a raised, serrated bar is present on one of the two sides of base that are orthogonal with respect to the hinge axis, a planar, swingable lever is embedded to the base by snapping or riveting one end of the planar, swingable lever to the same side as the serrated bar and configured to make the lever swingable around the snapped or riveted rotational axis, and wherein the snapped or riveted axis is parallel to the hinge axis. The connection mechanism can be, for example a snap configuration with a female snap member and a male snap member where the female snap member can have an inner groove to snap the male snap member in place.
Possibly at least two serrations are present on the serrated bar and the swingable lever slides along the serrated bar so that the swingable lever can stay at one or more positions along the serrated bar.
The swingable lever can swing around the snapped or riveted axis, and wherein the gap between a corresponding same side on the base and cover is configured to make the swingable lever substantially invisible while in use.
The end of the swingable lever opposite to the snapped or riveted end can be configured to mate with the corresponding area on the cover. The swingable lever can be configured so that while placed at the lowest serration on the serrated bar, the swingable lever engages with the cover at a fully closed position and a minimized cover plate assembly opening is formed.
Another embodiment can be implemented so that the end of the swingable lever opposite to the snapped or riveted end is configured to mate with the corresponding area on cover, and wherein the swingable lever is configured so that while retained at the highest serration on the serrated bar, the swingable lever engages with cover at a widely opened position and a maximized cover plate assembly opening is formed and wherein said maximized cover plate assembly is configured to accommodate heavy duty gauge cords.
In yet even another implementation of the invention disclosed herein an electrical outlet cover assembly can include a base, a cover for mating with the base, and a hinge. The hinge can be on one of the four sides of the cover corresponding respectively to the four sides of the base, and wherein the cover is hinged to the base so that the cover can swing forward and backward against the base by way of the hinge.

BRIEF DESCRIPTION OF THE DRAWINGS
The disclosure may be better understood with reference to the following drawings and description. The components in the figures are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the invention. Moreover, in the figures, like referenced numerals designate corresponding parts throughout the different views.
FIGS. 1A-1E depict an electrical outlet cover assembly.
FIGS. 2A-2E depict an electric outlet cover assembly in a closed state.
FIGS. 3A-3E depict an electrical outlet cover assembly in an open state.
FIGS. 4A-4C depict the base of an electrical outlet cover assembly.
FIGS. 5A-5K depict a variety of possible adapter plates and adapters.



DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The following discussion of the drawings are meant to describe certain embodiments, not all embodiments, such as would be discernable to one of ordinary skill in the art.
Turning now to FIGS. 1a-1e, we have various representations and orientations of an electrical outlet cover assembly 100. As can be seen in FIG. 1a, one embodiment of the invention consists of an outlet cover assembly 100 with a base 110, cover 150 and a hinge 810 capable of connecting the base 110 to the cover 150 so as to provide rotational freedom between the two for opening and closing the cover 150.
After regarding all FIGS. 1a-1e, it becomes apparent that the base 110 consists of 4 sides as well as a planar member 210 to serve as a bottom to the base 110. Planar member 210 will be shown in subsequent figures.
Further provided is a swingable lever 830. Lever 830 is connected to one side of the base 110 with a snap mechanism 840 (alternately referred to herein as simply the ‘snap’ 840). Snap 840 is configured so that the lever 830 can rotate about an orthogonal axis to the lever, around the snap 840. More detail will be provided below as to the snap mechanism 840.
A serrated bar 820 is also depicted. Serrated bar 820 could contain any number of serrations 821. For example, serrated bar 820 can have two or more serrations 821. In this embodiment, serrations 821 provide for the positioning of the lever 830 at different points on the serrated bar 820. In such a configuration it can be seen from the drawings that the height of cover 150 compared to base 110 adjusts depending upon which serration 821 along the serrated bar 820. As a result of multiple serrations 210, the cover 150 can adjust to multiple heights. For example, a cover 150 at a higher serration 210 can leave an open space between the cover 150 and the side of the base 110 opposite the hinge 810. This open space could accommodate an electrical cable, for example. Further, an even higher serration 210 could create an even larger open space for an even larger electrical cable.
Finally, an embodiment exists where the lever 830 is placed along the lowest serration 821 on the serrated bar 820 that enables the cover 150 to close completely over the base 110. This brings us to FIGS. 2a-2. 
FIGS. 2a-2e represent an electrical outlet cover assembly 100 that is closed. Closed electrical outlet cover assembly 900 can be seen from different orientations, 2a-2e and also includes cover 150, base 110 and hinge 810. In this particular embodiment, the cover 150 is designed to cover the lever 830 and serrated bar 820 from view.
Similarly, FIGS. 3a-3e depict an electrical outlet cover assembly 100 that is wide open. This open electrical outlet cover assembly 910 is seen from different orientations throughout FIGS. 3a-3e and, due to being open, provides additional information about an example planar member 210 (the bottom of the base 110).
First worth noting is that in this embodiment 910, we have depicted familiar elements including base 110, hinge 810, cover 150, snap 840, hinge 830, serrated bar 820, and serrations 821.
However, FIGS. 3c-3e contain examples of the bottom of the base 100, herein called the planar member 210. In certain embodiments the planar member 210 contains a mounting aperture 220. Mounting aperture 220 can be any size or shape, and not just the rectangular shaped aperture seen here. By way of non-limiting examples, mounting aperture 220 can be circular, rectangular, octagonal, smaller, larger and even multi-apertured.
In some embodiments, planar member 210 and mounting aperture 220 are configured to accept at least one detachable adapter 600 to it, as will be illustrated below, in FIG. 5.
Seen in FIGS. 4a-4c are embodiments of the invention with detailed snap mechanisms 840. Again, familiar elements can be seen such as base 110, hinge 810, serrated bar 820, serrations 821 and hinge 830. As always herein, similar elements in different embodiments does not limit the drawings in any way. Nor does it limit the discussion of the drawings, herein. Examples are always, just that: examples of preferred embodiments.
Also seen is an example of a snap mechanism 840. For example, snap mechanism 840 can comprise one or more female snap members 843 and one or more male snap members 842. Preferably, male snap members 842 and female spam members 843 are configured to mate to form a snap mechanism 840 for providing rotational motion to an attached lever 830. However, any snap mechanism 840 capable of providing rotational motion to a lever 830 and attach the lever 830 to one side of the base 110 will suffice.
Likewise, the snap mechanism 840 is attached to a particular side of the base 110 non-opposite to the hinge 810. Again, snap mechanism 840 can be attached to any side of the base 110. There may be embodiment where the snap mechanism 840 is placed elsewhere so long as it provides rotational motion to a lever 830 for allowing the cover 150 to open at several heights and allowing cables and such to enter the base 110.
Also seen in FIGS. 4b and 4c are planar members 210 and mounting apertures 220, the mounting apertures 220 configurable to accept one or more detachable adapters 600, 610, or 620, the discussion of which will begin now.
FIGS. 5a-5k depict embodiments of detachable adapter plates 500. FIG. 5a is an example of a detachable adapter plate (alternately referred to herein as simply ‘adapter plate’) configured to receive an electrical duplex socket 610. Meanwhile FIG. 5b is an adapter plate configured to receive a ground-fault circuit interrupt (GFCI) socket 620.
FIG. 5c is an adapter plate configured to receive an electrical round socket 600. Adapter plate 600 will serve to illustrate FIGS. 5c-5k as well. Pointing out, however, that the use of adapter plate 600 is for illustrative purposes only and adapter plates 610, 620 or any myriad of adapter plates configured to receive other sockets could have been used instead; all of which can by readily understood by one skilled in the art.
FIG. 5c also depicts a connection mechanism of tongue-like clips 730 in a “top and bottom” orientation. The tongue-like clips allow an adapter to connect firmly to another adapter. In particular, inwardly protruding tabs 701 can be seen. In only one example of how the detachable adapter 600 of 5c accepts a smaller, second adapter 510 inside of it, inwardly protruding tabs 701 mate with outward indentations 721 of FIG. 5d to secure a second adapter 510 to the first, detachable adapter 600.
The benefit of such a modular design is to allow flexibility over the size of the first aperture 501. In other words, in this embodiment second adapter 510 fits inside the first aperture 510 of the first, detachable adapter plate 600. Thus, the total aperture size is changed, or customized, by the marriage between the first adapter plate 600 and the second adapter 510. This process can be repeated ad infinitum, using a third adapter 520 that fits into the second adapter 510 to create a second aperture 512. A fourth adapter 530 can then be inserted inside the third adapter to form a smaller, third aperture 531, and so on and so forth, as illustrated by FIGS. 5e and 5f, respectively.
FIG. 5d also depicts a tabular connection mechanism of tongue-like tabs 730 for connecting adapter plates to other adapter plates. Please note that second adapter 510 depicts protruding tongue like tabs in a non-top/bottom orientation 711. However, protruding tabs can be found in any orientation including the top/bottom orientation 701 depicted in FIGS. 5c, 5e, 5i, 5j and 5k. 
FIG. 5g is a detachable adapter plate 500, 540 with a fourth aperture 541 shaped to receive an electrical toggle switch. Importantly, the fourth aperture 541 need not be the fourth aperture in succession, but is merely the fourth by way of our non-limiting example.
Regarding the tongue-like tabs (also referred to as ‘clips’) 701, 711 and indentations 721, both of which comprise an example of a tabular connection mechanism of tongue like tabs 730: In a preferred embodiment tongue like tabs 701, 711 are configured to fit snugly with indentations 721 and indentations 721 are preferably configured to fit snugly with tongue-like tabs 701, 711 so as to securely mate one adapter to another in a way that prevents movement between the two. By way of non-limiting example, this connection can be an actual connection, a friction based, connection or a simple snap in place design.
FIGS. 5h-5k provide some examples of how the preceding embodiments could possible work together.
In FIG. 5h, we have second adapter 510 placed inside the first aperture 501 of detachable adapter plate 600. In this illustration, indentations 721 of the second adapter 510 are mating with tongue-like tabs 701 of the detachable adapter plate 600. The non-top/bottom orientated tongue-like tabs 711 of the second adapter can easily be seen.
FIG. 5i depicts the third adapter 520 placed inside the first aperture 501 of detachable adapter plate 600. In this illustration, indentations 721 of the third adapter 520 are mating with tongue-like tabs 701 of the detachable adapter plate 600. At this point, the modular nature of the invention should be quite clear.
To further illustrate the nature of the invention, we have the example depicted in FIG. 5j. FIG. 5j depicts third adapter 520 placed inside the first aperture 501 of detachable adapter plate 600. In this illustration, indentations 721 of the third adapter 520 are mating with tongue-like tabs 701 of the detachable adapter plate 600. In addition, we can see the fourth adapter 530 snuggly inside the second aperture 521 of the third adapter 520. The resultant aperture is much smaller than the original on detachable adapter plate 600.
In this example tongue-like tabs 701 and indentations 721 are again used to mate the adapters together, however many other methods can be used to secure the adapters together.
Finally, we have FIG. 5k. FIG. 5k illustrates how a detachable adapter plate 600, which is configured to receive an electrically round socket, can be configured to receive a much smaller, rectangular adapter plate 630 which is configured to receive an electrical toggle switch. Here we have fifth adapter 540 placed inside the second aperture 521 of third adapter 520 using the familiar example mechanism of tongue-like tabs 701 and indentations 721. And using the same mechanism, third adapter 520 can be placed inside first aperture 501 of detachable adapter plate 600.
While various embodiments of the invention have been described, it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible within the scope of the invention. The various embodiments described herein include a variety of electrical elements and combinations of electrical elements, such as inductors, capacitors, voltage sources, switches, resistors, diodes, and power converters electrically coupled in various manners. The described example configurations of electrical elements and devices are examples that may be embodied through equivalent configurations having additional or fewer of the described elements, circuits, and devices, and alternative elements, alternative circuits, and/or alternative devices within the scope of invention. Accordingly, the invention is not to be restricted except in light of the attached claims and their equivalents.
