1. Field of the Invention
The present invention relates generally to modular power and utility receptacles. More particularly, the present invention relates to systems and methods for providing modular and versatile utility connections and accessories that may be installed in any workspace, and used for a variety of applications.
2. Description of the Related Art
Typically, homes or offices have specific locations where access to utilities, such as power and lighting, is provided. For example, in the kitchens of homes or restaurants, electrical outlet receptacles are usually located at particular locations on a wall, commonly called a backsplash, near or adjacent to a countertop. Therefore, the locations where electrical appliances such as blenders or toasters may be operated on the countertop are limited based on the locations of electrical outlet receptacles in the vicinity of the countertop.
Similarly, countertops can also provide space for performing work in a kitchen, such as preparing food or cleaning up after a meal. Task lighting is particularly critical to the performance of such tasks and is often installed overhead or beneath a cabinet and above the countertop. Therefore, the locations where such tasks may be performed may also be limited based on the locations of the task lighting in the vicinity of the countertop, which are generally fixed and cannot easily be changed.
In addition to electrical outlet receptacles and task lighting, the availability of other utility services and features, such as audio, video, Ethernet or Internet connections or consoles, is similarly limited based on the locations of service receptacles or portals in workspaces and in the vicinity of working areas, such as countertops.
Accordingly, there is a need for a customizable system for providing utilities and services, such as power, lighting and other applications, where they are needed most.
The present invention is directed to customizable systems and methods for providing utilities and services in convenient locations within workspaces, such as above or near a countertop in a kitchen. The present invention may include versatile structures and accessories that enable a user to customize the delivery of utilities and services to locations where they are needed most. Such structures and accessories may be installed within buildings during new construction, and may also be retrofitted into existing spaces.
According to a first aspect of the present invention, a customizable bus system includes a system module for supporting accessory modules and a power module for supplying power to the accessory modules. The system module may include a housing, such as a spine assembly, that is formed by a spine base and a spine cover. The spine base may include openings to connect wires and other services to the bus system, along with openings or apertures for mounting the spine bases to a surface, such as the underside of a cabinet or a backsplash or other wall. The spine cover may include openings for receiving and supporting accessory modules, and may be mounted to the spine base to form the spine assembly, for example, by snap-fitting the spine cover to the spine base, using one or more standard fasteners, such as screws or clips. Accessory modules may be placed into any of the openings in customized configurations defined by a user, and may also be removed from the openings by the user and replaced with other accessory modules or blanks.
The accessory modules are modular units that are interchangeable within various openings of the system module. Each of the accessory modules may include one or more electrical contacts that permit the accessory modules to receive power from the power module. The accessory modules may provide the bus system with accessories having different functionalities, including but not limited to lighting, electrical power receptacles, audio or video connections, Ethernet or Internet connections, Bluetooth® capabilities, docking stations or charging stations. For example, the bus systems of the present invention may provide lighting elements in the form of puck lights, arrays of light-emitting diodes (LED), tube lights or light trays. The accessory modules may also provide utility connections in the form of two- or three-prong electrical outlet receptacles, ground fault current interrupter (GFCI) outlet receptacles, category-5 (“CAT-5”) cable ports, telephone ports or universal serial bus (“USB”) ports. Furthermore, the bus systems may also include accessory modules that contain speakers, monitors, motion sensors, Bluetooth® or MP3 docking stations or other services. Additionally, accessory modules may be interchangeable within the accessory openings, and blanks may be installed into accessory openings within the system modules to cover accessory openings where an accessory is not needed.
The power module may include a power circuit and a power connection. The power circuit may include flexible wires and connective features, such as male or female connectors for interfacing with corresponding female or male connectors of accessory modules, or a rigid electrical conductor having a series of electrical contacts for providing power to one or more accessory modules. The power connection may provide power to the power circuit within the bus system from a power source by standard means, such as a hard-wired connection or a standard plug. The power module may provide alternating current (AC) or direct current (DC) power at one or more voltage levels, and may include one or more power circuits or tracks within the housing for conducting electricity. For example, the power module may include a single power supply that is maintained a constant voltage level, or one or more power supplies, each of which is maintained at a constant voltage level. The power module may also provide both a low voltage power supply, or track, for powering low-voltage applications such as lights, and a high power supply, or track, for powering high-voltage accessories such as electrical outlets or audio speakers. The power module may further include transformers for providing power at one or more additional voltage levels, as necessary. For high-voltage applications, the bus systems may preferably provide power at approximately 120 volts (V). For low-voltage applications, the bus system may preferably provide power at approximately 24 volts (V).
The bus systems may be formed of housings of one or more standard lengths, or of housings of one or more customized lengths, in order to comply with requirements of a particular application. Alternatively, the housings may be custom-designed to fit within a desired location or on a desired surface. For example, the housings may be formed of housings of twelve (12″), twenty-four (24″), thirty (30″) or sixty (60″) inches each. Additionally, the accessory openings in the housings may be modular or formed from regular dimensions, such as about three (3″) inches long each, and adapted to receive the accessory modules, which are also predictably sized, such as about three (3″) inches long each. The accessory openings may be provided at regular intervals, such as about six (6″) inches on center, or at any interval, as desired. Furthermore, the housings may be formed of any suitable material, such as extruded metal. Any traditional fasteners or mounting apparatuses, such as screws, nails, brackets, hooks, clips or adhesives, may be used to mount the bus systems to a surface, or to mate the various components of the bus systems together.
According to another aspect of the present invention, a customizable bus system includes a housing for supporting accessory modules, a power module for supplying power to the accessory modules, and a control panel. The housing may be formed from a spine base and a spine cover, and may include one or more accessory openings, mounting apertures, connecting wire apertures, one or more end caps, and one or more connectors. The spine base may be formed of any material, such as segments of extruded metal provided in varying lengths, and may also include one or more open ends which may be adapted to be closed with the end caps for a more pleasing visual appearance. The mounting apertures are adapted to slide over rotating clips or any other type of fasteners for securing the spine base onto an underside of a cabinet, a kitchen backsplash, or any other surface.
The control panel may be located anywhere within the system module, such as in one of the accessory openings in a spine base, or as an end cap to a housing or spine assembly. The control panel may link the system to and receive services from an existing junction box, and may also control the operation of one or more of the accessory modules, or the supply of power to the power circuits and/or one or more power conduits, or to individual accessory modules. The control panel may be used to control some or all of the entire bus system, and may be operated manually by a user using a wired or wireless means, such as a remote control, or operated automatically.
According to yet another aspect of the present invention, a customizable bus system includes one or more modular sticks, each having one or more accessory units included therein. Each accessory unit may include lighting, electrical power, docking stations, charging stations, audio or video connections, Ethernet or Internet connections, or other utility services. The modular sticks may be joined together by one or more connectors, and may include a power module for supplying power to the accessory units. The connectors may be formed from any material and may be either rigid or flexible. Additionally, the connectors may be formed in such a manner that permits a modular stick or accessory units to be installed in a variety of locations or configurations. The accessory units may be combined together to form the modular stick by placing a connector between each pair of accessory units. Additionally, a connector may include one or more accessory units therein.
One advantage of the bus systems of the present invention is that they provide custom solutions to improve power distribution, lighting flexibility and music enjoyment in a variety of spaces. In particular, a homeowner can modify or upgrade an existing system by providing light modules, electrical outlet receptacles, wireless speakers, USB ports, charging stations, docking stations, and other accessories in a basic system backbone. Although rooms typically have a finite number and limited locations of electrical outlets and utility ports, the present invention solves these and other limitations by allowing for customization of the electrical capabilities in a space, such as a kitchen, as well as providing features such as audio speakers or video displays, motion sensors, lighting and USB ports where desired. In particular, lighting accessory modules and electrical outlet accessory modules can be added where they are needed most, to increase the safety and efficiency of workers in a space. Additionally, by including one or more control panels in a bus system, the entire bus system may be easily controlled from any location in a space, or even outside of the space.
Another advantage of the bus systems of the present invention is the ease in which such systems may be installed and operated. For example, the bus systems may be powered by a hard-wired connection to an existing power supply, or through a standard plug that can draw power from existing outlet receptacles such as those on a kitchen backsplash. Alternatively, the bus systems may be installed in such a manner that conceals exposed wires in an attractive fashion, for example, by drawing power or utility services from an embedded junction box. Furthermore, the system is easily mounted to the underside of a cabinet or along a wall without interfering with the existing architecture in a space. Moreover, the bus systems can be installed by either a qualified professional or an ordinary homeowner.
These and other advantages of the present invention, and of the currently preferred embodiments thereof, will become more readily apparent in view of the following detailed description of the currently preferred embodiments and the accompanying drawings.
