1. Technical Field
This invention generally relates to covers for electrical devices, and more specifically relates to a convertible electrical device cover and method for installing same.
2. Background 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. Moreover, conventional covers usually are not capable of use with both single-gang and/or double-gang electrical device configurations. 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.
Another problem currently facing conventional covers may involve safety issues. For safety, the electrical device should at least be flush with access openings in plastic covers, and the electrical device should protrude through access openings in metal covers. Many conventional covers and related cover assemblies may be unsafe based on this fact. For example, some cover assemblies are designed to have a base separate an insert from the electrical device. Such a cover assembly may be unsafe if the thickness of the base is too great, the electrical device may not protrude far enough to be flush with or extend through the plastic or metal cover access openings respectively.
Accordingly, what is needed is an electrical device cover that overcomes the drawbacks of conventional non-convertible covers, such as the inability of safely protecting electrical devices in varying orientations and in a variety of styles and sizes, through a cover that may interchangeably and safely accommodate virtually all commonly encountered electrical devices used in conjunction with electrical device boxes. The invention has the advantage of being able to solve these problems through a convertible electrical device cover that is adaptable to safely accommodate a plurality of electrical devices in a plurality of orientations.
The convertible electrical device cover includes a base plate configured to safely accommodate an electrical device. The base plate may further include at least one removable tab that, upon removal, allows conversion into or formation of at least one access opening that is configured to accommodate at least one electrical device. In an embodiment, the base plate may include a pair of removable tabs that, upon removal, allow conversion into or formation of a pair of access openings for receiving a duplex electrical outlet. A removable center tab that separates the pair of access openings, as well as four corner tabs, may also be included in the embodiment. The center and corner tabs may be removed to form an access opening for receiving a ground fault current interrupter outlet. Additionally, a pair of flanking tabs forming portions of the pair of access openings may be included as well in the embodiment, which may also be removed to form a larger access opening. Therefore, the base plate may be a “blank” comprising a continuous network of removable tabs, the removal of which may convert the base plate to accommodate a plurality of electrical devices.
The convertible electrical device cover also includes an adapter plate configured to safely accommodate an electrical device. The adapter plate may be located between the electrical device and a rear side of the base plate when the convertible electrical device cover is placed in an operative position over the electrical device. Alternatively, the base plate may be located between the electrical device and a rear side of the adapter plate when the convertible electrical device cover is placed in an operative position over the electrical device. In either of these alternative embodiments, a front face of the electrical device may be at least flush with a front side of the adapter plate, thereby ensuring a safer operating condition. In another embodiment, the adapter plate may be configured to abut the base plate on all sides of a larger access opening formed by removal of the pair of removable tabs and the center, corner, and flanking removable tabs of the exemplary base plate embodiment generally described above.
The adapter plate may further include at least one removable tab that, upon removal, allows conversion into or formation of at least one access opening that is configured to accommodate at least one electrical device. In an embodiment, the adapter plate may include features similar to the pair of removable tabs and the removable center, corner, and flanking tabs of the exemplary base plate embodiment generally described above. In another adapter plate embodiment, the adapter plate may include a removable tab that, upon removal, allows conversion into or formation of an access opening configured to accommodate a toggle switch. A substantially circular removable tab defining the access opening may also be included in the embodiment. The substantially circular removable tab may be removed to form a substantially circular access opening for receiving a round outlet. A substantially annular removable tab encompassing the substantially circular removable tab may be included as well in the embodiment, which may be removed to form a larger substantially circular access opening for receiving a larger round outlet. Therefore, the adapter plate may be a “blank” comprising a continuous network of removable tabs, the removal of which may convert the adapter plate to accommodate a plurality of electrical devices.
The convertible electrical device cover may further include an engaging mechanism. When a convertible electrical device cover is placed in an operative position over an electrical device, the engaging mechanism may be configured to either removably couple a front side of the adapter plate to a rear side of the base plate facing the electrical device, or removably couple a rear side of the adapter plate to a front side of the base plate, so that a front face of the electrical device may be held in at least a flush engagement with the front side of the adapter plate. The engaging mechanism may also be configured to position the adapter plate to accommodate an electrical device positioned in a plurality of orientations.
In another embodiment, the engaging mechanism may include opposing protrusions on a rear side of the base plate facing the electrical device, the opposing protrusions defining receiving notches positioned inwardly toward one another. Pins may also be provided that may be removably coupled to and extend outwardly from opposing sides of the adapter plate, the pins configured to removably couple into the receiving notches defined in the opposing protrusions so that a front side of the adapter plate may be removably coupled to a rear side of the base plate and a front face of the electrical device may be held in at least a flush engagement with the front side of the adapter plate.
In yet another embodiment, the engaging mechanism may include a recess. The recess may be defined in a rear side of a base plate facing an electrical device so that a front side of an adapter plate may be removably coupled into the recess, thereby holding a front face of the electrical device in at least a flush engagement with the front side of an adapter plate. Alternatively, the recess may be defined in a front side of a base plate so that a rear side of an adapter plate may be removably coupled into the recess and a front face of the electrical device may be held in at least a flush engagement with the front side of an adapter plate.
In still another embodiment, the engaging mechanism may include electrical device box screws and opposing top and bottom key holes that extend fully through the adapter plate and that align with underlying opposing top and bottom key holes in the base plate. The electrical device box screws may extend through the key holes in both the adapter and base plates and into the electrical device box screws holes so that a rear side of the adapter plate may be removably coupled to a front side of the base plate and a front face of the electrical device may be held in at least a flush engagement with the front side of the adapter plate.
The invention also includes a method for installing a convertible electrical device cover according to the present invention. Generally, the installation method may include the step of placing the convertible electrical device cover in an operative position over an electrical device so as to locate an adapter plate between the electrical device and a rear side of a base plate. Alternatively, the installation method may include the steps of: removing at least one removable tab of a base plate that is configured to accommodate at least one electrical device, thereby converting the base plate to accommodate at least one electrical device; removing at least one removable tab of an adapter plate that is configured to accommodate at least one electrical device, thereby converting the adapter plate to accommodate the at least one electrical device; and placing the convertible electrical device cover in an operative position over an electrical device so as to locate a base plate between the electrical device and a rear side of an adapter plate. In either of these alternative installation method embodiments, a front face of the electrical device may be at least flush with a front side of the adapter plate, thereby ensuring a safer operating condition.
The alternative installation method embodiments may further include the steps of: either utilizing an engaging mechanism to removably couple a front side of an adapter plate to a rear side of a base plate facing the electrical device, or utilizing an engaging mechanism to removably couple a rear side of an adapter plate to a front side of a base plate, so that a front face of the electrical device may be held in at least a flush engagement with the front side of the adapter plate; and/or utilizing an engaging mechanism to position an adapter plate to accommodate a plurality of orientations of an electrical device.
The foregoing and other features and advantages of the invention will be apparent from the following more particular description of embodiments of the invention, as illustrated in the accompanying drawings.
The present invention and embodiments will hereinafter be described in conjunction with the appended drawings, where like designations denote like elements, and:
Generally, a convertible electrical device cover adaptable to safely accommodate a plurality of electrical devices in a plurality of orientations is provided. The convertible electrical device cover may interchangeably, yet safely, accommodate virtually all commonly encountered styles and sizes of electrical devices used in conjunction with electrical device boxes. The convertible electrical device cover includes an assembly 222 (

Base plate 110 may further include at least one removable tab that, upon removal, allows conversion into or formation of at least one access opening that is configured to accommodate at least one electrical device. Thus, base plate 110 may be a “blank” comprising a continuous network of removable tabs, the removal of which may convert base plate 110 to accommodate a plurality of electrical devices. Alternatively, base plate 110 may include at least one access opening that is configured to safely accommodate at least one electrical device. In either of these alternative embodiments, the at least one access opening of base plate 110 may be generally substantially rectangular or substantially square, although other polygonal, circular, and the like shapes are within the scope of this invention, and the at least one access opening may be of sufficient size to accommodate one or more electrical devices in a plurality of styles and orientations. For example, base plate 110 with the at least one access opening may be configured to accommodate at least two electrical devices, such as in the two-gang electrical device configuration of convertible electrical device cover 200 in
Turning to
Not withstanding the foregoing, many other combinations of removable tabs may be defined by base plate 110 according to the present invention, the removal of which may convert base plate 110 to accommodate a plurality of electrical devices. For example, base plate 110 may include removable tabs that yield access openings to receive a rocker-type light switch, a modular phone jack, a cable television outlet, or other electrical device. Additionally, the present invention may provide base plate 110 to be extremely versatile, such as in the co-pending patent application to Shotey et al. entitled “UNIVERSAL COVER PLATE,” Ser. No. 09/657,352, filed Sep. 7, 2000, which is incorporated herein by reference. Thus, base plate 110 may include sets of removable tabs that are configured to form access openings to receive a variety of electrical devices. The tab sets are bounded by tab set periphery lines that may intersect each other, and the resulting access openings are bounded by access opening periphery lines that may intersect each other. Tab sets and potential access openings may overlap or they may include other tab sets or potential access openings. Also, any of several different combinations of the tab sets described in the previously incorporated reference may be provided within base plate 110. Thus, for example, a top duplex tab set, a bottom duplex tab set, a light switch tab set, a small single round tab set, a larger single round tab set, and a GFCI tab set may all be provided together within base plate 110. Thus, the present invention may provide a large variety of possible base plate 110 configurations without requiring a user to stock several different electrical device covers.

Base plate 110 also may define box screw hole tabs 174. Box screw hole tabs 174 may comprise thinned areas of base plate 110 and may be located on a line parallel to the shorter sides of base plate 110 and approximately passing through key holes 170. Thus, box screw hole tabs 174 may be located one on either side of keyhole 170 and substantially equidistant from a head hole of key hole 170. If base plate 110 has two key holes 170, a pair of box screw hole tabs 174 will preferentially be located one on either side of both key holes 170, producing the configurations shown. The thickness of base plate 110 at box screw hole tabs 174 may be approximately half or a quarter of its thickness elsewhere, making it possible to use a sharp instrument such as a nail to punch through the material of base plate 110 at the location of box screw hole tabs 174, thus creating box screw mounting holes at each location.
Different device screw holes may be utilized depending on the configuration of base plate 110. Thus, removable center tab 114 of base plate 110 may define center mounting screw hole 178 in the duplex configuration of base plate 110 in

Therefore, adapter plate 150 may define different device screw holes depending on the configuration of adapter plate 150. Thus, removable center tab 114 of adapter plate 150 may define center mounting screw hole 178 in the duplex configuration of adapter plate 150 in FIGS. 2 and 8-13. Adapter plate 150 may also define mounting screw holes 176 in the switch and round configurations of adapter plate 150 in
When convertible electrical device cover 100 is placed in an operative position over an electrical device, adapter plate 150 may be located between the electrical device and a rear side of base plate 110 facing the electrical device (e.g.

Specifically, opposing protrusions 142 defining receiving notches 144 positioned inwardly toward one another. Pins 152 may also be provided that may be removably coupled to and extend outwardly from opposing sides of adapter plate 150. Pins 152 are configured to removably couple into receiving notches 144 defined in opposing protrusions 142 so that a front side of adapter plate 150 may be removably coupled to a rear side of base plate 110 and a front face of the electrical device may be held in at least a flush engagement with a front side of adapter plate 150. Receiving notches 144 may be located off-center of a center line parallel to longer sides of base plate 110. Moreover, additional receiving notch 146 may be included, it being defined in one of opposing protrusions 142. Likewise, additional pin 154 may be included, additional pin 154 removably coupled to and extending outwardly from a side of adapter plate 150. Additional pin 154 may be configured to removably couple into additional receiving notch 146, thereby properly positioning adapter plate 150 relative to opposing protrusions 142.
Yet another embodiment of the engaging mechanism that is configured to removably couple a front side of adapter plate 150 to a rear side of base plate 110 may include at least two opposing rails on the rear side of base plate 110. Adapter plate 150 may be configured to be slidably removably coupled between the at least two opposing rails so that a front side of adapter plate 150 may be removably coupled to a rear side of base plate 110 and a front face of the electrical device may be held in at least a flush engagement with a front side of adapter plate 150.

In practice, then, it would be typical for a user of the present invention to remove an unused pair of hinges and leave only that pair to which the protective cover may be to be attached. On the other hand, if there were a possibility that the protective cover configuration would change from time to time, raising the possibility of the alternate use of multiple pairs of hinges, each pair of hinges 180 could be left in place to serve as pivotal attachment locations when needed. Furthermore, it should be understood that the hinge configuration shown in
Convertible electrical device cover 100 may also include a protective housing 224, which may be particularly useful in outdoor settings where a weatherproof cover plate may be desired. Thus, the protective housing 224 could provide an opening for the passage of a cord extending from a plug inserted into an electrical outlet, for example, such that the plug may remain in the outlet and the electrical device to which the other end of the plug and the cord are attached may remain in operation when the protective housing 224 is in its closed position (
Components of convertible electrical device cover 100 may be made from any of many different types of materials. For example, base plate 110 and adapter plate 150 may be made from weather-resistant, rigid, electrically non-conductive materials such as polycarbonate, polystyrene or other plastic materials known in the art. Base plate 110 and adapter plate 150 may also be made from corrosion-resistant metal, such as zinc, magnesium, or other metals known in the art. For example, aluminum may also be used, although aluminum is not particularly resistant to corrosion in a salt water environment. Notwithstanding, base plate 110 and adapter plate 150 may be made from other materials suitable for electrical applications. The components of convertible electrical device cover 100 may be manufactured separately and then assembled together. Base plate 110 and adapter plate 150 may be manufactured by injection molding, casting, milling, metal stamping, or the like. Base plate 110 and adapter plate 150 may then be assembled together through an installation method as described below when convertible electrical device cover 100 is placed in an operative position over the electrical device.
Describing the installation and use of convertible electrical device cover 100 further, a method for installing convertible electrical device cover 100 may also be provided to safely accommodate a plurality of electrical devices in a plurality of orientations. As depicted in
The first installation method embodiment may further include removing at least one removable tab of base plate 110, thereby converting base plate 110 to accommodate the at least one electrical device. Specifically, removing at least one removable tab of base plate 110 can include forming at least one access opening that is configured to accommodate the at least one electrical device. For example, as depicted in
The first installation method embodiment may still further include removing at least one removable tab of adapter plate 150, thereby converting adapter plate 150 to accommodate the at least one electrical device. Specifically, removing at least one removable tab of adapter plate 150 may include forming at least one access opening that is configured to accommodate the at least one electrical device. For example, removing at least one removable tab of adapter plate 150 may include removing center removable tab 114 and corner removable tabs 116 forming part of access openings 130 that are configured to accommodate a duplex electrical outlet (the various removable tabs and access openings depicted in
As another example, removing at least one removable tab of adapter plate 150 may further include removing substantially circular removable tab 162 forming access opening 160 configured to accommodate a toggle switch (the removable tab and access opening depicted in
The first installation method embodiment may further include the step of utilizing an engaging mechanism to removably couple a front side of adapter plate 150 to a rear side of base plate 110 so that adapter plate 150 is located between the at least one electrical device and the rear side of base plate 110 when convertible electrical device cover 100 is placed in an operative position over the at least one electrical device, and so that at least one front face of the at least one electrical device is held in at least a flush engagement with the front side of adapter plate 150. Additionally, the step of utilizing an engaging mechanism may further include positioning adapter plate 150 to accommodate the at least one electrical device positioned in a plurality of orientations.

Other than the just described distinctive steps, further possible steps of the second installation method embodiment are similar to the possible steps of the first installation method embodiment as described above, the above description incorporated herein by reference to describe the further possible steps of the second installation method embodiment. Therefore, only one other different possible step between the two installation method embodiments will be further described. Specifically, the second installation method embodiment may further include utilizing an engaging mechanism to removably couple a rear side of adapter plate 150 to a front side of base plate 110 so that base plate 110 is located between the at least one electrical device and the rear side of adapter plate 110 when convertible electrical device cover 100 is placed in an operative position over the at least one electrical device, and so that at least one front face of the at least one electrical device is held in at least a flush engagement with the front side of adapter plate 150.
While the invention has been particularly shown and described with reference to embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention. Accordingly, unless otherwise specified, any components of the convertible electrical device cover according to the present invention indicated in the drawings or herein are given as an example of possible components and not as a limitation. Similarly, unless otherwise specified, any steps or sequence of steps of the installation methods according to the present invention indicated herein are given as examples of possible steps or sequence of steps and not as limitations.
