## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims the benefit of and priority under 35 U.S.C. 119(e) of U.S. Provisional Patent Application No. 62/091,368, entitled INTERCHANGEABLE ELECTRICALLY POWERED MODULES AND RECEPTACLES THEREFOR, filed Dec. 12, 2014 in the name of John S. Haw, the disclosure of which is incorporated herein by reference.


FIELD OF THE INVENTION
This invention relates generally to electrically powered apparatus and particularly to electrically powered apparatus which utilize devices housed within interchangeable modular apparatus together with cooperating electrically powered receptacles.
BACKGROUND OF THE INVENTION
In a typical electrically powered receptacle of the type commonly used in both residential and commercial facilities, a protective metal or plastic box is supported within a wall opening and defines an outwardly oriented open face. A plurality of power coupling wires are threaded to the interior of the protective metal box. A receptacle configured to be received within and supported by the protective box supports one or more receptacles which are electrically connected to the power carrying wires within the box. A protective cover plate is mounted upon the exterior open face of the protective box and extends about the periphery of the wall opening receiving the protective box. In most instances, the protective cover defines appropriately sized and arranged apertures which allow access to the plug receptacles.
In typical use, a number of differently configured appliances, tools, lights and other electrically powered apparatus are plugged into a plug receptacle to tap electrical power for operation of the apparatus. Many devices such as electronic equipment, computers and other electronic devices operate at lower voltages and current than the conventional available electric power. Accordingly, such devices require an adapter and power converter which, in essence, plugs into the available electric power within the receptacle and converts the higher voltage electric power to a lower voltage and current typical of the operative supply voltages and currents for electronic and computer devices.
While the presently used power converters and adapters employed for operating computers and other electronic equipment utilizing conventional powered receptacles has to some extent enjoyed commercial success and extended use, the use of such adapters often proves to be impractical, costly, cumbersome and in some instances unsafe. Many computer and electronic apparatus operate utilizing internal battery power supplies which must be recharged utilizing adapters and the like. All of this leads to a substantial clutter and inefficiency as multiple adapters and power converters are utilized in a typical home, office or commercial establishment.
As a result of the ever expanding use of computer and other electronic apparatus within the typical home, office and commercial establishment, a long-felt and unresolved need arises for systems more appropriately adapted to the use of power devices. There remains a more extended use for systems which accommodates such devices and which avoid the need for individual adapters and power converters while efficiently and effectively providing convenient electrical power for such apparatus.
There remains a further need for apparatus that increases the flexibility and effective use of the wall outlets within an electric power system by introducing the capability of multiple use modules that connect an otherwise conventional electric power box to a plurality of functional units having electric power and digital and electronic communication capability along with a variety of system functionality.
SUMMARY OF THE INVENTION
Accordingly, it is a general object of the present invention to provide an improved system for utilizing electrical power access in accommodating and powering computer and other electronic devices. It is a more particular object of the present invention to provide an improved system for accommodating and powering computer and electronic devices which provides a plurality of interchangeable modularized and electrically powered receptacles for use in providing electrical power to such devices.
The present invention provides a plurality of interchangeable, electrically powered, modules and receptacles for use therewith. The interchangeable electrically powered modules are configured and capable of providing a variety of electrical and electronic devices. Each receptacle is configured to be secured to and supported by an otherwise conventional electric back box. The receptacles preferably utilize a bayonet mount receptacle which is standardized for the entire system and which accommodates each and every module in a twist-lock mounting system. Each module includes a cooperating bayonet mount attachment for use with the receptacle bayonet mounts. The use of a bayonet mount attachment for the modules to the receptacle provides a standardized power and data coupling for the module devices which is connected by a simple insert and partial turn locking action. Conductive pads on the interior surface of the receptacle adjacent the bayonet mount receptacle slots, engage the cooperating bayonet mount tabs of the modules to provide connection for electric power and data transmission. The receptacle may provide a single device receiving receptacle or alternatively, provide accommodation for a pair of receptacles or by further alternate configuration, a quartet of modules.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
By way of overview, the present invention provides a receptacle mounting plate supported by an otherwise conventional wall mounted electric back box which mounting plate supports a single receptacle, a pair of receptacles or a quartet of receptacles. Each receptacle being standardized in shape and configuration and each being capable of receiving any one of a plurality of interchangeable operative modules. The invention further includes a plurality of interchangeable electrically powered modules capable of providing a variety of functional operations and each supporting a standardized coupling structure for cooperatively engaging with any of the sockets within the modular device receptacle. In the preferred fabrication of the present invention, the sockets and the engaging mounting structure of the modules provide an otherwise conventional and twist bayonet mount structure. As a result, each module may be operatively plugged into and engage any of the available sockets within any available receptacle and receive operative electrical power and transmit data therefrom. Because the modules and cooperating receptacles are able to provide engagement and disengagement of a module without the need to interrupt the power to the receptacles, the modules are “hot-swapping” in operation. This provides substantial advantage as modules are moved to and from receptacles as desired.
FIG. 1 sets forth a perspective view of a module receptacle constructed in accordance with the present invention and generally referenced by numeral 10. Module receptacle 10 is shown supporting a pair of plug-in modules 20 and 30. In accordance with the present invention, module receptacle 10 includes a generally planar front plate 11 defining a pair of module receiving apertures 12 and 13. Module receptacle 10 further includes a module housing 40 extending rearwardly from the back surface of front plate 11 and further includes a module housing 50 also extending rearwardly from the back surface of front plate 11. As is better seen in FIGS. 2 and 3, module housing 40 and module housing 50 are substantially cylindrical and are aligned with apertures 12 and 13 respectively (seen in FIG. 1). As is also better seen in FIG. 3, modules 20 and 30 are generally cylindrical and sized to be inserted into module housings 40 and 50. In accordance with an important aspect of the present invention, a plurality of different electronic and digital functional modules may be interchangeably inserted into module receptacle 10. In the example shown in FIG. 1, module 20 defines a front face 21 which in turn defines a pair of grip surfaces 22 and 23.

It will be recalled that the present invention further includes a plurality of interchangeable electrically powered modules each capable of providing one, or more, of a variety of functional operations and each supporting a standardized coupling structure for cooperatively engaging with any of the sockets within the module receptacle 10. In the preferred fabrication of the present invention, the sockets and the engaging mounting structures of the modules provide an otherwise conventional and twist operated bayonet mount structure. As a result, each module may be operatively plugged into and engage any of the available sockets within any available module receptacle, such as module receptacle 10, and receive operative electrical power and transmit data therefrom. It will also be recalled that the modules and cooperating receptacles are able to provide engagement and disengagement of a module without the need of interrupting the power to the receptacles. This provides substantial advantage as modules are moved to and from receptacles as desired.
Continuing in FIG. 7 and as is described above, module receptacle 10 includes a generally planar front plate 11 defining apertures 12 and 13. A pair of threaded fasteners 14 and 15 are supported by front plate 11. Module receptacle 10 further includes a pair of generally cylindrical module housings 40 and 50 extending rearwardly from back surface 91. Module housing 40 defines a module-receiving cavity 43.

Bayonet receptacles 44 and 54 each define a plurality of slots, such as slots 45 and 55 which receive tabs 82 and 83 of terminal connector 80 (seen in FIG. 3).
Continuing in FIG. 7, plug-in modules 20 and 30 are received within module-receiving cavities 43 and 53 (seen in FIG. 9) of module receptacle 10. Plug-in module 20 includes a front face 21 having grips 22 and 23 formed therein. As is better seen in FIG. 1, front face 21 further defines a plurality of plug apertures 24, 25 and 26 which receive conventional plug prongs for electrical connection. Plug-in module 20 includes a bayonet cap 28 which completes plug-in module 20 and includes a bayonet mount 92 (better seen in FIG. 22). Bayonet mount 92 is of conventional fabrication and will be understood to cooperatively engage bayonet receptacle 44 to mechanically support plug-in module 20 and make required electrical connections to plug-in module 20. Plug-in module 20 also includes a functional circuit 29 which performs module functions such as electronic communications, or the like. Similarly, plug-in module 30 includes a front face 31 having grips 32 and 33 formed therein.

Plug-in module 30 includes a bayonet cap 38 which completes plug-in module 30 and includes a bayonet mount 93 (better seen in FIG. 22). Bayonet mount 93 is of conventional fabrication and will be understood to cooperatively engage bayonet receptacle 54 to mechanically support plug-in module 30 and make required electrical connections to plug-in module 30. Plug-in module 30 also includes a functional circuit 39 which performs module functions such as data communications, or the like.
In accordance with an important feature of the present invention, cap segments 18 and 19 of cap unit 16 each support a permanent magnet 78 and 79. Correspondingly, bayonet caps 28 and 38 of plug-in modules 20 and 30 respectively support permanent magnets 68 and 78 respectively. As each plug-in module is inserted into a module housing, the magnet supported by the cap segment and the magnet supported by the plug-in module bayonet cap are brought into close proximity. Because the magnets are oriented to bring like magnetic poles together, a repulsive magnetic force is created that urges the plug-in module outwardly from the module receptacle. As a result, once the module is rotated to release its bayonet connection, the magnets push the plug-in module outwardly a short distance which in turn aids plug-in module withdrawal.
With temporary reference to FIG. 34 below, a cooperating feature of the present invention use of a bayonet type attachment for the plug-in modules may be discussed at this point. FIG. 34 sets forth a section view of module receptacle 10 taken along section line 34-34 in FIG. 5.

Similarly, terminal connector 80 is supported against the opposite side of module housings 40 and 50 and includes a tab 82 extending into bayonet receptacle 44 and a tab 83 extending into bayonet receptacle 54. Module 20, shown inserted into module housing 40, includes a plurality of radially extending bayonet tabs 48, 49 and 56 which engage bayonet receptacle 44. Plug-in module 20 also includes connectors 94, 89 and 90 which are supported upon bayonet tabs 48, 49 and 56 respectively. Tabs 62 and 82 contact connectors 89 and 94 to provide electric power. In addition, bayonet tabs 48 and 49 and connectors 94 and 89 define shallow detent recesses which receive the convexly curved portions of tabs 82 and 62 to provide a spring detent of the bayonet attachment between module 20 and bayonet receptacle 44.
In a similar manner and with continued reference to FIG. 34, module 30, shown inserted into module housing 50, includes a plurality of radially extending bayonet tabs 75, 76 and 77 which engage bayonet receptacle 54. Plug-in module 30 also includes connectors 66 and 67 which are supported upon bayonet tabs 75 and 76 respectively. Tabs 75 and 76 contact connectors 66 and 67 to provide electric power. In addition, bayonet tabs 75 and 76 and connectors 66 and 67 define shallow detent recesses which receive the convexly curved portions of tabs 83 and 63 to provide a spring detent of the bayonet attachment between module 30 and bayonet receptacle 54. The detent positioning of modules 20 and 30 thus provided maintains the fully seated rotational positions of the modules within the module receptacles.

Further examples include a wireless network (Wi-Fi) extender which includes an ethernet port of various types (including, but not limited to, RJ-45 and USB) that also allows the extender to function as a bridge for connecting home theater components; task light/night light with wireless (of aforementioned protocols) and manual control and programming a security camera (stationary, pan/tilt and pan/tilt/zoom) of various manufacture and wireless control protocol: audio speaker/intercoms that are connected (either wirelessly via aforementioned protocols, conventionally by internal electrical wiring, or directly with a USB cable) to a home entertainment system, cell phone, computer or similar device, and a motion detector that is wirelessly controlled, programmed and monitored may be utilized.
It will be noted that while the primary method of mounting modules to modular device receptacles, and of transferring power from a receptacle/mounting plate to a module is obtained with a bayonet mount connection as described herein, alternate mounting and power transfer can be obtained by various other means. Examples of alternative means include but are not limited to audio type jacks, including RCA type, secured with a Chicago screw; audio type jacks, including RCA type, secured with a DZUS type fastener; and twist-lock type (NEMA configuration) connectors including, but not limited to, representative types of connections by Hubble (Hubblelock), Omega (PT Series Connectors), Molex (MX150), Pass & Seymour pin and sleeve connector, BNC type, and other similar connectors.
While particular embodiments of the invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the invention in its broader aspects. Therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of the invention.
