1. Technical Field
Aspects of the present disclosure relate generally to wall plates and wall plates which are electrically active and receive and/or convey electrical current.
2. Background Art
Wall plates are well known and are used to fill in the space between an electrical box and an electrical device. Specifically, the wall plates are known to provide a more aesthetically pleasing appearance while also preventing access to the electrical device. By preventing access to the electrical device, the user is safer because electrical wiring is not readily accessible.
Wall plates are also known to provide a simple lighting source or powering portable devices USB, but are commonly unsafe and rely on direct, spring biased connections with an installed electrical receptacle. These spring biased electrical connections are unsafe due to the inherent unreliability of the spring biased connections which may short or become damaged over time, leading to electrical and/or fire hazards.

Embodiments of the present invention will hereinafter be described in conjunction with the appended drawings, where like designations denote like elements, and:
This disclosure, its aspects and implementations, are not limited to the specific components or assembly procedures disclosed herein. Many additional components and assembly procedures known in the art consistent with the intended operation and assembly procedures for a powered wall plate will become apparent for use with implementations of a powered wall plate from this disclosure. Accordingly, for example, although particular components are disclosed, such components and other implementing components may comprise any shape, size, style, type, model, version, measurement, concentration, material, quantity, and/or the like as is known in the art for such implementing components, consistent with the intended operation of a powered wall plate.
Powered wall plate 10 is secured to electrical device 28 or the electrical box with screws 30 and an adapter 27 which is complimentary shaped to the electrical device 28. For example, since electrical device 28 may be shaped or sized differently, an appropriate adapter will be utilized. Electrical device 28 includes current mounting screws 29 which are adapted to receive electrical wires 44. Electrical wires 44 connect at current mounting screws 29 and hard wire current transfer plug 40 which connects to wall plate current feature 42.
Moving to hard wire current transfer plug 40 in more detail, an electrode transfer portion 41 includes a current transfer contact 43 which is secured within the housing of current transfer plug 40 for each current path. Accordingly the current transfer plug can easily slide onto wall plate current feature 42 to securely and efficiently transfer electrical current from wire 44 and ultimately electrical device 28 to the wall plate through wall plate current feature 42 and into a wall plate interface 39 as seen in
Installation of the hard wired powered wall plate 10 is simple in that the installer removes the original wall plate and unscrews the electrical device mounting screws. Next, electrical wire 44 is connected to the electrical device current mounting screws 29 and reinstalls electrical device 28 within an electrical box. The current transfer plug 40 on the other end of electrical wire 44 is then connected to each wall plate current feature 42 before the powered wall plat 10 is secured with screws 30. The installer may then reenergize the circuit and have USB power, lighting, and control of the electrical current provided to wall plate 10. In one implementation, the installer may include an adapter around the opening 16 of the wall plate depending on the electrical device 28 used and may install a cap 45 to prevent electrocution or electrical shorts.
Advantageously, the powered wall plate can include any number of circuits to provide any number of usable features within the spirit and scope of the present disclosure. While examples include USB ports, LED lighting, a photocell, a control circuit, or the like, any suitable input, output, or control circuit may be implemented in the powered wall plate. Still further, the hard wire option shown in
Wall plate 10 includes a plug-in module 32 having a front surface 36, prongs 34, and arms 46 extending outward from each side. Arms 46 each include a current transfer unit 48 having a current transfer contact 50 therein. Each current transfer contact 50 is operatively connected to prongs 34 to receive electrical current from the electrical device and transfer the electrical current to the circuit board via wall plate interface 39 and wall plate current feature 42 to power the wall plate. Each current transfer unit 48 may include an aperture 51 adapted to receive the wall plate current feature 42 adjacent current transfer contact 50.
Plug-in module 32 may also be oriented to slide plugs 34 upwards or downwards to ensure that the plug-in module can be utilized with any type of electrical device and still transfer electrical current to the wall plate current feature 42. For example, the plug-in module body may include rivets 47 arranged to receive apertures 49 which are elongated and may include a recessed portion. The recessed portion allows the rivets 47 to be compressed at the head and allow the plugs 34 to move upward and downwards relative to the rivets 47 but still be retained to prevent disconnection. This upward or downward relative movement may be important in some circumstances where device dimensions vary. Specifically, the distance between the powered wall plate mounting screw and the upper or lower electrical prong apertures on electrical device 28 may be different for a duplex receptacle, a decorator receptacle, or a GFCI receptacle for example or due to manufacturer styles. With the incorporation of this adjustable feature, the powered wall plate 10 is designed to work regardless of the device style or manufacturer, saving time, energy, and retailer stocking needs.
The plug-in module 32 may also include spring biased shutters 71 which surround plugs 34. Shutters 71 are compressed by the electrical device front face when the wall plate is appropriately positioned or are used to ensure that a user is not electrocuted if a portion of electrical plug 34 would otherwise be visible due to a gap between the wall plate and the electrical device. Operation is simple and the spring is biased to the extended position and compressed as appropriate, thereby prevent direct access to the plugs 34 by a user after installation but still allowing full plug prong insertion if possible. If spring biased shutters 71 are omitted, a spacer 37 may be utilized to restrict access to the prongs 34 and prevent electrocution.
Installation of the powered wall plate with the plug-in module includes positioning the plug-in module 32 on the wall plate current feature 42, then installing the wall plate on the electrical device and potentially sliding the plug-in module prongs 34 upwards or downwards slightly to align with the electrical device. Finally, the powered wall plate 10 is secured to the electrical box or electrical device with screws 30. In an alternative installation, the plug-in module 32 is positioned in the electrical device and the wall plate is then positioned so the wall plate current features 42 fit within aperture 51 of arms 46, thereby connecting the plug-in module 32 and the wall plate 10 to transfer current. Regardless of the order of the steps used to install the powered wall plate, the plug-in module 36 provides a simple and efficient way to power the wall plate without hard wiring and may instead be used as a user selected alternative to hard wiring.
While
From a functional stand point, the powered wall plate 10 shown in
Moving to
The at least one mounting screw aperture 106 extends through the wall plate 102 and is configured to receive at least one mounting screw 122 (see
The electrical circuit 108 is located between the front surface 112 and the rear surface 114. In some embodiments, the electrical circuit 108 comprises a printed circuit board (see
The powered wall plate 100 may additionally comprise a control switch 124 configured to control the supply of power to the electrical feature 110. Thus, when the control switch 124 is in an on position and power is supplied to the at least two electrical plug prongs 104, power is supplied to the electrical feature 110 as well. When the control switch 124 is in an off position and power is supplied to the at least two electrical plug prongs 104, the electrical feature 110 remains without power and is turned off In addition, in some embodiments, the control switch 124 has an auto position. When the control switch 124 is in the auto position, the control switch 124 selectively provides power to the electrical feature 110. For example, in embodiments where the electrical feature 110 is a light 126, the control switch 124 in the auto position may selectively turn on the light 126 based on an ambient light level. The ambient light level may be measured by a photocell 128. The light 126 may be an LED light, and may be at least one light or a plurality of lights. In embodiments with a light 126, the powered wall plate 100 may also comprise a window 129 through the wall plate 102 which exposes the light 126 through the front surface 112. The light 126 may be located along a bottom edge 130 of the wall plate 102.
The wall plate 102 may have a protruding front face 132 extending forward of the front surface 112. In such embodiments, the photocell 128 may be exposed on the protruding front face 132 and the control switch 124 may be positioned on the protruding front face 132. In addition, the electrical circuit 108 may be located between the protruding front face 132 and the rear surface 114. The rear surface 114 may comprise a circuit back cover 134, which is removably coupled to the wall plate 102. For example, the circuit back cover 134 may be attached to the wall plate 102 with screws. The circuit back cover 134 is configured to cover the electrical circuit 108 when the circuit back cover 134 is installed on the wall plate 102, as shown in
The protruding front face 132 may be located on a bottom half 136 of the wall plate 102. In addition, as shown in
It will be understood that implementations are not limited to the specific components disclosed herein, as virtually any components consistent with the intended operation of a method and/or system implementation for a powered wall plate may be utilized. Components may comprise any shape, size, style, type, model, version, class, grade, measurement, concentration, material, weight, quantity, and/or the like consistent with the intended operation of a method and/or system implementation for a powered wall plate.
The concepts disclosed herein are not limited to the specific implementations shown herein. For example, it is specifically contemplated that the components included in a particular implementation of a powered wall plate may be formed of any of many different types of materials or combinations that can readily be formed into shaped objects and that are consistent with the intended operation of a powered wall plate. For example, the components may be formed of: rubbers (synthetic and/or natural) and/or other like materials; polymers and/or other like materials; plastics, and/or other like materials; composites and/or other like materials; metals and/or other like materials; alloys and/or other like materials; and/or any combination of the foregoing.
Furthermore, embodiments of the powered wall plate may be manufactured separately and then assembled together, or any or all of the components may be manufactured simultaneously and integrally joined with one another. Manufacture of these components separately or simultaneously may involve extrusion, pultrusion, vacuum forming, injection molding, blow molding, resin transfer molding, casting, forging, cold rolling, milling, drilling, reaming, turning, grinding, stamping, cutting, bending, welding, soldering, hardening, riveting, punching, plating, and/or the like. If any of the components are manufactured separately, they may then be coupled or removably coupled with one another in any manner, such as with adhesive, a weld, a fastener, any combination thereof, and/or the like for example, depending on, among other considerations, the particular material(s) forming the components.
In places where the description above refers to particular implementations of a powered wall plate, it should be readily apparent that a number of modifications may be made without departing from the spirit thereof and that these implementations may be applied to other powered wall plate. The accompanying claims are intended to cover such modifications as would fall within the true spirit and scope of the disclosure set forth in this document. The presently disclosed implementations are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the disclosure being indicated by the appended claims rather than the foregoing description. All changes that come within the meaning of and range of equivalency of the claims are intended to be embraced therein.
