Description




BACKGROUND OF THE INVENTION




The present invention relates generally to power strips, and particularly to power strips of a modular nature, whereby electrical power may be provided for various types of electrical devices and/or connections, such as power supply cords, incoming telephone lines, cable TV protection using coaxial connections, local area networks (LAN's), and wide area networks (WAN's).




More particularly, the present invention relates to power strips having multiple modules, and surge protection capability. In modern homes and offices, it is convenient to use a single power strip for multiple electrical appliances or electrical lines. Unfortunately, in the typical office or home, because such appliances and electrical lines are located by necessity or choice at different locations remote from other such appliances or lines, it often becomes necessary to employ more than one power strip in a single room, or use one or more extension cords running from the various appliances to a single power strip. When multiple power strips are used or electrical extension is required, the presence of the additional power strips and/or extension cords often contributes to an unsightly appearance and may result in a safety hazard if not carefully placed so as to avoid pedestrian traffic and the like.




In addition, electrical lines, such as AC power lines, telephone lines, data lines and coaxial cable lines are subject to accidental power surges. These power surges are a condition wherein an abnormally high current and/or voltage is transmitted over the electrical line. Power surges can be caused by lightning or short circuits. The surge can cause permanent damage to devices connected to the electrical line.




Therefore, surge protectors have been developed to detect surges and to block the surge before it reaches devices on the electrical line. Generally, surge protectors are divided into two different types; primary and secondary.




Primary surge protectors are generally located where electrical lines enter a building and are designed with a relatively large “surge capacity” so that they can protect against relatively large surges. Secondary surge protectors, on the other hand, are generally located on the inside of a building. It is common to place a secondary surge protector on an AC power line between a wall outlet and a computer, or other electrical appliance. In addition, primary and secondary surge protectors are further divided into surge protectors for each type of electrical line. The various types of electrical lines have different constructions, different kinds of interfacing hardware and are subject to different types of surges. Furthermore, the various types of electrical lines typically follow different paths within a building. For instance, telephone lines run to telephone jacks, while AC power lines run to power outlets.




BRIEF SUMMARY OF THE INVENTION




It is an object of the present invention to provide a power strip having multiple modules.




It is a further object of the present invention to provide a power strip having multiple modules capable of being placed at different locations to accommodate numerous and various electrical appliances and electrical lines.

DETAILED DESCRIPTION OF THE INVENTION




A modular power strip, generally designated by the numeral


10


, in accordance with the present invention is shown in perspective in

FIGS. 1 and 5

.




The modular power strip


10


as shown in the drawings comprises a first


12


and second


14


power supply module that can be removably and matingly connected to one another. The modules


12


and


14


are generally elongated and are formed of any rigid material such as plastic, metal, ceramic or any combination thereof.




First and second modules


12


and


14


generally comprise an upper surface


16


, a generally hollow underside


18


, a first end


20


and


22


, a second end


24


and


26


, and a first elongated side


28


and


30


and a second elongated side


32


and


34


, said elongated sides extending parallel to each other and perpendicular to the first ends and second ends of each module. The upper surface


16


of the first


12


and second


14


modules has a generally raised portion


36


at the first ends


20


and


22


, and a generally depressed portion


38


extending from said raised portion


36


to the second ends


24


and


26


. The depressed portion


38


of the upper surface


16


of modules is shown to include one or more electrical outlets


40


. In a preferred embodiment, the upper surface


16


of the raised portion


36


of module


14


is shown to include a switch


42


and an electrical cord


44


extending from the first end


22


of the second module


14


having a plug (not shown) for connection to a power supply, including a wall outlet, an extension cord, generator or power strip. The switch


42


controls the flow of electrical power from the electrical cord


44


to the switched electrical outlets


40


so that power can be switched either on or off.




A second cord


46


extends from the underside of the second end


24


of the first module


12


to the second end


26


of the second module


14


to allow electrical current to flow from the electrical outlet through the first


12


and second


14


modules. If additional modules are desired or needed, a third cord (not shown) may extend from the first end


22


of the second module


14


to connect with the first end of the third module to provide electrical current to the third module (not shown). Additional modules and cords may be connected as needed or desired in accordance with the description set forth herein. The length of the second cord


46


or any additional cords (not shown) needed or desired is limited only by consumer preference.




In another embodiment, one of the modules is equipped with a wallmounting apparatus (not shown) allowing the module to be mounted on a wall and directly plugged into a wall outlet, thereby eliminating the need for a first cord for such electrical connection.




In a preferred embodiment, the modular power strip


10


of the present invention comprises two separate modules


12


and


14


connected by a cord


46


preferably four feet in length. It is to be understood, however, that the length of the cord may be any suitable length. When surge protection is required at locations remote from one another, the modules


12


and


14


can be disconnected and separated from one another and placed at remote locations as necessary or desired. The distance from which one module can be placed from the other module is limited only by the length of the cord extending between two or more modules.




When a power strip is needed at a single location, the modules


12


and


14


of the present invention can be matingly and removably connected to form a single unit. Preferably, each module is connected along one or more of their elongated sides. For example, in a preferred embodiment, the second elongated side


32


of the first module


12


has at least one tab


48


protruding outwardly from the second elongated side


32


of the first module


12


that engages one or more apertures

in the first elongated side


30


of the second module


14


. As shown in

FIG. 1

, when connected by the connecting means, the first and second modules


12


and


14


form a single unit that may be used as a single power strip at a single location. Similarly, an additional module may be connected to the second elongated


34


side of the second module


14


and so forth.




As shown in

FIGS. 2 and 3
