BEST MODE FOR CARRYING OUT THE INVENTION
The ensuing detailed description is exemplary of the preferred embodiment of the present invention, the scope of which is limited only by the claims appended hereto.
Referring to FIG. 1, there is shown power and communication trough 10 in accordance with one embodiment of the present invention. Power and communication receptacle trough 10 generally comprises frame 12 that comprises downwardly extending walls 13A, 13B, 13C and 13D, and upper, peripheral portion 14. Upper, peripheral portion 14 is attached to walls 13A, 13B, 13C and 13D. Upper, peripheral portion 14 comprises top portion 14A, a stepped portion 14B, and flanged or extending portion 14C. When frame 12 is positioned within an opening in a work surface of an article of furniture, flanged or extending portion 14C contacts and sits upon the work surface. Trough 10 further includes a pair of covers 16 and 18 that are pivotally or hingedly attached to upper, peripheral portion 14 by any suitable technique or means. In one embodiment, hinges are used to attach covers 16 and 18 to upper, peripheral portion 14. In a preferred embodiment, covers 16 and 18 are identical in size, shape and construction. Referring to FIGS. 1, 2 and 10, trough 10 is configured to be used with article of furniture 90 which has work surface 92 and opening 93 in the work surface 92. Opening 93 defines sides or edges 94. In one embodiment, fasteners such as screws or nails are used to attach downwardly extending walls 13A, 13B, 13C and 13D to sides 94. In another embodiment, a clamping device (not shown) is used to clamp the entire frame 12 to the article of furniture. Other techniques may be used to attach frame 12 to the article of furniture. If the materials used to fabricate trough 10 are relatively heavy, the entire weight of trough 10 may be sufficient to maintain the trough 10 in a stationary, secure position in the article of furniture without the use of any fasteners or clamping devices.
Referring to FIGS. 1, 2 and 3, trough 10 further comprises receptacle attachment member 20 that comprises base 21A, sidewalls 21B, 21C, and end portions 22 and 24. End portion 22 is attached to interior wall 30 of downwardly extending wall 13A of frame 12. Similarly, end portion 24 is attached to the interior wall (not shown) of downwardly extending wall 13B. Fasteners 32 are used to attach end portions 22 and 24 to downwardly extending walls 13A and 13B, respectively. This is just one technique of attaching end portions 22 and 24 to walls 13A and 13B, respectively. It is to be understood that end portions 22 and 24 can be attached to frame 12 via other techniques or configurations. Sidewalls 21B and 21C are attached to sidewalls 13C and 13D, respectively, of frame 12 by any suitable technique, e.g. screws, rivets, etc.
Referring to FIGS. 1-5, in accordance with one embodiment of the present invention, receptacle attachment member 20 has a wave-like shape or contour. Receptacle attachment member 20 is discussed in detail in the ensuing description. Trough 10 further comprises a plurality of communication receptacles 40, a plurality of power receptacles 42 and a plurality of data signal receptacles 44 that are attached or connected to receptacle attachment member 20. Communication receptacles 40 can be configured as RJ45 receptacles suitable for telephone or internet connections. Each receptacle 40 has rear connectors that are configured to be connected to wire or cables that are connected to a telephone or internet network. Power receptacles 42 are configured to provide A.C. voltage (e.g. 117 VAC) to power office or laboratory equipment, e.g. personal computers, oscilloscopes, etc. Each power receptacle 42 has rear connectors that are configured to be connected to wires or cables that are part of power cord 68 which is described in the ensuing description. Each data receptacle 44 is configured as a typical multi-bit digital signal connector used with personal computers or computer peripheral devices, e.g. RS-232, RS-422 and RS-485. It is to be understood that other types of connectors and receptacles can be connected to receptacle attachment member 20 as well (e.g. USB, video, XLR, etc.). Trough 10 includes circuit breaker 46 is mounted to receptacle attachment member 20 and is configured to provide overload protection. As shown in FIG. 2, frame 12 includes support member 50 that spans the central portion of frame 12. Trough 10 further includes power cover 60 that comprises sidewalls 62 and 64, horizontal base 66, and end walls 67A and 67B. Power cover 60 totally encloses the underside of receptacles 42 so as to prevent contact between the users and wires or connectors carrying 117 VAC. Trough 10 also includes power cord 68 that is electrically connected to receptacles 42 and to a power or energy source (not shown) and thus, provides electrical power to receptacles 42. In one embodiment, power cord 68 extends through horizontal base 66. In another embodiment, power cord 68 extends through sidewall 67B.
Referring to FIGS. 1-4, in accordance with one embodiment of the present invention, receptacle attachment member 20 has a wave-like shape or contour which comprises crest or peak portion 70 and lower portions 72 and 74. The portion of receptacle attachment member 20 that extends from end portion 22 to crest 70 defines one half of receptacle attachment member 20. The portion of receptacle attachment member 20 that extends from end portion 24 to crest 70 defines the other half of receptacle attachment member 20. One advantage of receptacle attachment member 20 is that since receptacle attachment member 20 can be viewed as having two halves 80 and 82, it is easier for a user to identify a particular receptacle to which a specific piece of equipment is plugged. For example, a user may wish to plug all computer related equipment into the receptacles of half 80 and all oscilloscopes and meters into receptacles of half 82. Another advantage of receptacle attachment member 20 is that two individuals that are simultaneously using the same article of furniture can also simultaneously use trough 10 without being confused as to whose equipment is plugged into a particular receptacle. For example, one person could plug all of his or her equipment into the receptacles on half 80 of receptacle attachment member 20, and the other person can plug all of his or her equipment into half 82 of receptacle attachment member 20. There would be no confusion as to who plugged a piece of equipment into a particular receptacle.
Referring to FIGS. 6, 7 and 10, power and communication receptacle trough 10 is positioned within opening 93 of article of furniture 90. Sidewalls 13A, 13B, 13C and 13D are attached to sides 94 of opening 93. Flanged portion 14C of upper, peripheral portion 14 physically contacts and sits upon work surface 92 when frame 12 is completely positioned within opening 93. In order to facilitate viewing of opening 93, trough 10 is not shown in FIG. 10.
Referring to FIGS. 2, 4 and 5, trough 10 utilizes two covers 16 and 18 instead of one cover. This is because the user may only need to use one half, either half 80 or half 82, of receptacle attachment member 20. Cover 16 is pivotally or hingedly attached to one side of upper, peripheral portion 14 of frame 12, and cover 18 is pivotally or hingedly attached to the opposite side of upper, peripheral portion 14. The covers 16 and 18 are arranged in this manner to accommodate persons on either side of the article of furniture. FIG. 6 shows both covers 16 and 18 in the open position. FIG. 7 shows both covers 16 and 18 in the closed position.
Although receptacle attachment member 20 has been described as having a wave-like shape or geometry, it is to be understood that receptacle attachment member 20 can be configured to have other geometries and contours that achieve the same advantages as described in the foregoing description. For example, in FIG. 8, there is shown receptacle attachment member 100 in accordance with another embodiment of the present invention. Receptacle attachment member 100 has a generally triangular shape. An additional advantage of this receptacle attachment member 100 is that in the event liquids are accidentally spilled on receptacle attachment member 100, the liquids will quickly run off the receptacle attachment member 100. Receptacle attachment member 100 includes a pair of sidewalls, one of which being sidewall 101. A plurality of power and communication receptacles 102 are attached to receptacle attachment member 100. In FIG. 9, there is shown receptacle attachment member 200 in accordance with a further embodiment of the present invention. Receptacle attachment member 200 comprises a pair of sidewalls, one of which being sidewall 201. Receptacle attachment member 200 is configured to have a stair-case or terraced shape configuration that comprises steps or terraces 202, 204, 206 and 208. A plurality of power and/or communication receptacles 210 are connected to receptacle attachment member 200. It is to be understood that frame 12 would have to be modified in order to accommodate either receptacle attachment member 100 or receptacle attachment member 200. For example, downwardly extending walls 13A and 13C would have to be extended downward an additional distance so that the ends of receptacle attachment members 100 or 200 could be attached thereto.
Referring to FIGS. 1, 6 and 11, power and communication receptacle trough 10 further comprises at least one light device 300. In one embodiment, each light device 300 is configured as an LED. As shown in FIG. 11, one of the light devices 300 is attached to the upper portion of sidewall 21C of receptacle attachment member 20. In one embodiment, there are four light devices 300 wherein two light devices 300 are attached to the upper portion of sidewall 21C and the other two light devices 300 attached to the upper portion of sidewall 21B of receptacle attachment member 20. The lighting devices 300 illuminate the interior of trough 10 in the event the room is dark or dimly lit. Trough 10 further comprises power receptacle 310 and step-down transformer 312 that are attached to sidewall 62 of power cover 60. Power receptacle 310 is electrically connected to power cord 68 and to step-down transformer 312. Trough 10 further comprises switch 320 that is attached to receptacle attachment member 20 and electrically connected to step-down transformer 312. Each light device 300 is electrically connected to switch 320. The power cord 68 supplies electrical power to power receptacle 310. Step-down transformer 312 reduces this power to a voltage that is suitable for light devices 300. For example, in one embodiment, each light device 300 is configured to operate on 12 volts. Switch 320 has a first state that provides the stepped-down voltage to light devices 300 and a second state that disconnects the light devices 300 from the stepped-down voltage.
A variety of materials may be used to fabricate apparatus 10, e.g. plastic, metals, resins, composites, etc.
The size of power and communication receptacle trough 10 may be varied depending upon the application.
