At least one power outlet 32 and/or at least one communication outlet 34 is connected to outlet panel 30 such that the power and communication outlets 32 and 34, respectively, face outward. Outlet 32 is configured to provide A.C. voltage (e.g. 117 VAC) to power office or laboratory equipment, e.g. personal computers, oscilloscopes, etc. Wires (not shown) are connected to connectors (not shown) on the rear of outlet 32 so as to provide electrical power from an electrical power source (not shown). In this embodiment, communication outlet 34 comprises an RJ45 connector that provides connection to a communication network such as a telephone communication network or the internet. Wires, which are not shown, are connected to connectors (not shown) on the rear of outlet 34 and the aforesaid communication network.
Referring to FIGS. 1 and 2, retractable power and communication outlet apparatus 10 further comprises cover plate member 40 that is attached to top end 24 of shell 22 via screws 41. Retractable power and communication outlet apparatus 10 further comprises bottom plate member 42 which is attached to bottom end 26 of shell 22. Bottom plate member 42 has portions 42A, 42B and 42C that extend beyond the perimeter of shell 22. Bottom plate member 42 has top side 44 and bottom side 46. Retractable power and communication outlet apparatus 10 further comprises vertically oriented slide apparatus 50. Vertically oriented slide apparatus 50 comprises stationary rail member 52 and movable member 54 that slides upon slide member 52 whereby movable member 54 can slide upward or downward with respect to rail member 52. Movable member 54 has a top end portion that is connected to bottom side 46 of bottom plate member 42 such that outlet structure 20 moves upward or downward with movable member 54. Thus, slide apparatus 50 allows outlet structure 20 to move between a retracted position and an extended position. When outlet structure 20 is in the extended position, the power outlet 32 and communication outlet 34 are positioned above the work surface of the desk, work bench or similar article. When outlet structure 20 is in the retracted position, the power outlet 32 and communication outlet 34 are positioned below the work surface. Retractable power and communication outlet apparatus 10 further comprises mounting plate 60 that is generally perpendicular to longitudinally extending axis 62 of slide apparatus 50 and has cut-out area 64 that is sized to allow outlet structure 20 to vertically move there-through. Mounting plate 60 has top side 66 and bottom side 67. Top side 66 is configured to be attached to the bottom side of a work surface. Mounting plate 60 includes a plurality of through-holes 68 through which screws 69 are inserted in order to attach mounting plate 60 to the bottom side of a work surface. This feature will be explained in detail in the ensuing description.
Referring to FIG. 1, retractable power and communication outlet apparatus 10 further comprises magnets 70 and 72 that are attached to bottom plate member 42. Each magnet 70 and 72 has a portion thereof protruding through top side 44 of bottom plate member 42. Each magnet 70 and 72 extends for a portion of the width of bottom plate member 42. When outlet structure 20 is in the extended position, magnets 70 and 72 are magnetically attached to bottom side 67 of mounting plate 60 so as to maintain outlet structure 20 in the extended position. In order to position outlet structure 20 in the retracted position, the user pushes down on cover plate member 40 so as to break the magnetic bonds between magnets 70 and 72 and bottom side 67 of mounting plate 60 and enable moveable member 54, with outlet structure 20 attached thereto, to slide downward on rail member 52.
Referring to FIGS. 2, 3 and 4, there is shown retractable power and communication outlet apparatus 10 operatively connected to an article of furniture 100 having work surface 102, bottom side 104 and opening 106. Opening 106 is sized to allow outlet structure 20 to pass there-through. Mounting plate 60 is attached to bottom side 104 via screws 69 such top side 66 of mounting plate 60 contacts bottom side 104 of article of furniture 100. Slide apparatus 50 is positioned below work surface 102 and stationary rail member 52 is attached to a lower portion (not shown) of article of furniture 100. FIGS. 2, 3 and 4 show outlet structure 20 in the extended state wherein magnets 70 and 72 are magnetically attached to bottom side 67 of mounting plate 60 and power outlet 32 and communication outlet 34 are located above work surface 102 and accessible to the user. FIG. 6 shows outlet structure 20 in the retracted state. The manner in which outlet structure 20 is configured into the extended state is described in the ensuing description.
Referring to FIG. 4, in a preferred embodiment, grommet sleeve 120 is positioned in the top portion of opening 106 of article of furniture 100. Rim 122 of grommet sleeve 120 contacts work surface 102. FIG. 6 shows outlet structure 20 in the retracted state. When outlet structure 20 is in the retracted state, cover plate member 40 sits upon rim 122 of grommet sleeve 120.
Referring to FIGS. 4 and 6, cover plate member 40 has cut-out 200. When outlet structure 20 is in the retracted position, cut-out 200 forms an opening 220 that is in communication with opening 106 in article of furniture 100. When outlet structure 20 is in the extended state, an A.C. voltage cord can be plugged into power outlet 32. Outlet structure 20 can then be positioned in the retracted position and cut-out 200 allows the A.C. voltage cord to remain plugged into power outlet 32. Thus, A.C. power cords connected to electrical equipment located on work surface 102 can extend through opening 220, down through opening 106 of article of furniture 100 and be connected to power outlet 32 while outlet structure 20 is in the retracted state. In the same manner, a communication cable or wire can extend through opening 220 and remain plugged into communication outlet 34 when outlet structure 20 is in the retracted state.
FIG. 6 shows outlet structure 20 in the retracted state. In order to configure outlet structure 20 in the extended state, the user simply inserts his or her finger into opening 220, grasps cover plate member 40 and lifts outlet structure 20 upward. This causes moveable member 54 to move upward as well. The user continues to lift outlet structure 20 upward until magnets 70 and 72 contact and become magnetically attached to bottom side 67 of mounting plate 60.
FIG. 5 shows the retractable power and communication outlet apparatus 10 of the present invention with a modification. Specifically, the RJ45 outlet is replaced with USB port 250. It is to be understood that other types of power and communication outlets can be used on outlet panel 30 as well.
A variety of materials may be used to fabricate apparatus 10, e.g. plastic, metals, resins, composites, etc.
The size of retractable power and communication outlet apparatus 10 and components thereof may be configured to have any suitable size.
While the foregoing description is exemplary of the present invention, those of ordinary skill in the relevant arts will recognize the many variations, alterations, modifications, substitutions and the like are readily possible, especially in light of this description, the accompanying drawings and the claims drawn hereto. In any case, because the scope of the invention is much broader than any particular embodiment, the foregoing detailed description should not be construed as a limitation of the present invention, which is limited only by the claims appended hereto.
