BACKGROUND
Embodiments described herein relate generally to plug strips, and in particular to reconfigurable plug strips.
Currently, electrical and other outlets typically include a limited number of outlets usable to plug in devices requiring electrical power, or requiring access to a signal path and/or a signal source. When additional outlets are needed, a plug strip can be coupled to a permanent outlet, which increases the number of outlets available. However, the outlets on such plug strips may be oriented so that devices such as power adapters having large housings in fixed orientation with respect to their electrical plugs can obstruct some of the outlets, reducing the benefit of the plug strip. Furthermore, the length and/or width of the plug strip can limit the locations where the plug strip can be placed.
Thus a need exists for a reconfigurable plug strip.

FIG. 1A is a perspective view of a plug strip in a first configuration, according to an embodiment. Plug strip 100 can be a reconfigurable plug strip, and can include a set of segments movably connected to one or more other segments. Plug strip 100 can be, for example, a 120 volt, 3 prong plug strip. Specifically, plug strip 100 includes a base segment 120, a first assembly 110 and a second assembly 190. The first assembly 110 includes two intermediate segments 140a and 140b and an end segment 160a. Similarly, the second assembly 190 also includes two intermediate segments 140c and 140d and an end segment 160b. The base segment 120 includes a recess 122 that can be configured to receive a portion of a signal port coupler 125. The base segment 120 can also include and/or be operatively coupled to a ring member (not shown in FIGS. 1A-1F) that can allow the first assembly 110 and/or the second assembly 190 to rotate around the base segment 120. Hence, base segment 120 is the pivot point around which the first assembly 110 and the second assembly 190 can rotate. The base segment 120 can also include and/or be operatively coupled to an electrical connection assembly that can be configured to selectively engage the electrical receptacles of the different intermediate segments 140a-140d and/or the different end segments 160a-160b as shown in U.S. Pat. No. 8,262,399, (the '399 patent), entitled “Reconfigurable Plug Strip,” filed Apr. 27, 2011, the contents of which are hereby incorporated herein by reference in their entirety. Hence, base segment 120 can be configured to define an electrical signal path between the base segment 120 and a signal port, the intermediate segments 140a-140d, and/or the end segments 160a-160b. The base segment 120 can also include a retraction mechanism (not shown in FIGS. 1A-1F) that can be used to retract at least a portion of the power cord 125a. The base segment 120 also includes a power button 121 and a light indicator 123. The light indicator 123 can display a continuous colored light or flash a colored light when the plug strip 100 is in a first state (e.g., a power-on state) and is operational.
The first assembly 110 includes first intermediate segment 140a movably coupled to the base segment 120. The first intermediate segment 140a can include a first electrical receptacle 145a that can receive at least an electrically conductive portion of a first device plug. The first assembly 110 also includes a second intermediate segment 140b that is movably coupled to the first intermediate segment 140a. The second intermediate segment 140b can include a second electrical receptacle 145b that can receive at least an electrically conductive portion of a second device plug. Additionally, the first assembly 120 can include a first end segment 160a that is movably coupled to the second intermediate segment 140b. The first end segment 160a can include a third electrical receptacle 145c that can receive at least an electrically conductive portion of a third device plug. The first end segment 160a includes a recess 168a that can be configured to receive a portion of a signal port coupler 125 (or power cord 125a). In some configurations, the first assembly 110 can be movable about the base segment 120 about a single axis in a single plane. For example, the first assembly 110 can be configured to rotate about the base segment 120 around an axis of rotation marked AA′ in FIG. 1A from a first position to a second position where the second position is 90 degrees offset from the first position. In other configurations, the base segment 120 and the first assembly 110 may be movable relative to each other in one or more other planes and/or about or along one or more other axes. Similarly, in some configurations, the second intermediate segment 140b and the first end segment 160a may be movable relative to each other about a single axis in a single plane. In other configurations, the second intermediate segment 140b and the first end segment 160a may be movable relative to each other in one or more other planes and/or about or along one or more other axes.
The second assembly 190 includes a third intermediate segment 140c movably coupled to the base segment 120. The third intermediate segment 140c can include a third electrical receptacle 145c that can receive at least an electrically conductive portion of a third device plug. The second assembly 190 also includes a fourth intermediate segment 140d that is movably coupled to the third intermediate segment 140c. The fourth intermediate segment 140d can include a fifth electrical receptacle 145e that can receive at least an electrically conductive portion of a fifth device plug. Additionally, the second assembly 120 can include a second end segment 160b that is movably coupled to the fourth intermediate segment 140d. The second end segment 160b can include a sixth electrical receptacle 145f that can receive at least an electrically conductive portion of a sixth device plug. The second end segment 160b includes a recess 168b that can be configured to receive a portion of a signal port coupler 125 (or power cord 125a). In some configurations, the second assembly 190 can be movable about the base segment 120 about a single axis in a single plane. For example, the second assembly 110 can be configured to rotate in a clockwise direction about the base segment 120 around an axis or rotation marked AA′ in FIG. 1A from a first position to a second position where the second position is 90 degrees offset from the first position. In other configurations, the base segment 120 and the second assembly 190 may be movable relative to each other in one or more other planes and/or about or along one or more other axes. Similarly, in some configurations, the fourth intermediate segment 140d and the second end segment 160b may be movable relative to each other about a single axis in a single plane. In other configurations, the fourth intermediate segment 140d and the second end segment 160b may be movable relative to each other in one or more other planes and/or about or along one or more other axes. In some configurations, each of the moving segments may lock into two or more positions as defined by the direction of rotation (e.g., fully open, fully closed, etc.). Although FIG. 1A shows the first assembly 110 and the second assembly 190 each to include two intermediate segments, in other embodiments, the first assembly 110 and the second assembly 190 can include more or less than two intermediate segments. Although FIG. 1A shows the each of the intermediate segments 140a-140d and the end segments 160a-160b to include a single electrical receptacle 145a-145f, in other embodiments each of the intermediate segments 140a-140d and the end segments 160a-160b can include more than one electrical receptacle.
In some embodiments, the plug strip 100 can include a plastic or metal housing (not shown in FIGS. 1A-1F). In such configurations, the housing can be covered by a rubber-over-mould. This rubber-over-mould can provide the plug strip 100 protection against drops and other hazards in harsh environments (e.g., a construction job site). FIG. 1G is a top view of the plug strip in a second configuration, according to an embodiment. In such configurations, the base segment recess 122 is shown to receive a portion of the signal port coupler 125 that includes a power cord 125a. In such configurations, the base segment recess 122 and the signal port coupler recess of the two end segments 168a and 168b permit the power cord 125a to be wrapped around the plug strip 100. The base segment recess 122 can define a handle portion 126 that can be used for hanging the plug strip 100 from, for example, a nail, a hook, or any other suitable hanging mechanism.
In some configurations, the power cord 125a of the signal port coupler can include a ground fault circuit interrupter (GFCI) unit 125f at the end of the power cord 125a (as shown in FIG. 1G). Alternatively, in other configurations, the GFCI unit can be located with the plug strip 100 (e.g., in the base segment 120). The GFCI unit 125f can be used to shut off an electric circuit when current is detected as flowing along an unintended path, possibly through water or through a user and thus GFCI units 125f can be used to reduce the risk of electric shock. The GFCI unit 125 can measure the current leaving the hot side of a signal port (e.g., a power source) and compare it to the current returning to the neutral side. If the two currents are not equal, this indicates that some of the current is flowing along an unintended path, and the GFCI unit 125f can be configured to automatically shut off the supply of power to the plug strip 100. In some configurations, the plug strip 100 can be made to be Occupational Safety and Health Administration (OSHA) certified for specific high-risk job site use by, for example, making the plug strip 100 compliant with OSHA standard 1926.403.
More information regarding the exemplary methods and structure for achieving the above-described movability of the different segments in the plug strip is set forth in the '399 patent incorporated by reference above. The '399 patent also describes exemplary methods and structure for providing power distribution functionality to the base segment and/or each of the intermediate segments and end segments of the first assembly and/or the second assembly.
FIG. 2 is a partially exploded perspective view of the plug strip showing the direction of movement of the first assembly and the second assembly, according to an embodiment. FIG. 2 shows that the first assembly 210 is operatively coupled to a ring member 211 that is disposed around the base segment 220 and allows the first assembly 210 to rotate around the base segment 220. Specifically, the ring member 211 is part of and/or attached to the first intermediate segment 240a of the first assembly 210 and allows the first intermediate segment 240a to rotate around the base segment 220. Similarly, FIG. 2 also shows that that the second assembly 290 is operatively coupled to a ring member 291 that is disposed around the base segment 220 and allows the second assembly 290 to rotate around the base segment 220. Specifically, the ring member 291 is part of and/or attached to the third intermediate segment 240c of the second assembly 290 and allows the third intermediate segment 240c to rotate around the base segment 220. The mechanical link assembly 228 can serve as a scaffold to hold the ring members 211 and 291 and allows the ring members 211 and 291 to move in a substantially arcuate motion around the mechanical link assembly 228. In the embodiment of the plug strip 200 shown in FIG. 2, the first assembly 210 moves in a counter-clockwise orientation around the base segment 220, and the second assembly 290 move in a clockwise orientation around the base segment 220.
A printed circuit board and switch 226 can form a portion of the electrical connection assembly that can conductively engage the different electrical receptacles of the intermediate and end segments of the first assembly 210 and the second assembly 290 with a signal port. The printed circuit board and switch 226 can also engage the power button 221 when the power button 221 is actuated by a user (e.g., downward force applied on the power button 221 by a user) to define a signal path between a signal port the plug strip 200. The printed circuit board and switch 226 can also include the electrical circuitry to engage the indicator ring 223 to display, for example, a continuous light or a flashing light when the plug strip 200 is in an activated configuration. The top cap 224 serves as a cover for the ring member 291 and is part of the mechanical housing that contains the different components of the base segment 220. Additionally, the top cap 224 also houses the power button 221 and the indicator ring 223. The bottom cap 234 serves as a cover for the ring member 211 and is a part of the mechanical housing that contains the different components of the base segment 220. Additionally, in some configurations, the top cap 224 and/or the bottom cap 234 can include a locking mechanism (e.g., mechanical stoppers) that can be used to limit the motion of the first assembly 210 and/or the second assembly 290 and also lock the first assembly 210 and/or the second assembly 290 in specific locations about the base segment 220.
FIGS. 3A and 3B are a top and bottom perspective views of an intermediate segment, according to an embodiment. The intermediate segment 340 includes a top housing 341 and a bottom housing 351. The top housing 341 defines an aperture 342 that is configured to receive a portion of the top housing of an adjacent intermediate segment when the intermediate segment 340 is connected to an adjacent intermediate segment (e.g., intermediate segment 140a connected to intermediate segment 140b as seen in FIG. 1A). The aperture 342 that can also be configured to receive a portion of the base segment when the intermediate segment 340 is connected to a base segment (e.g., intermediate segment 140a to base segment 120 as seen in FIG. 1A). The intermediate segment 340 includes a pair of rotation posts 343a and 343b that can be disposed in the pair of arcuate rotation channels 349 defined by an adjacent or neighboring intermediate segment to allow pivotal movement of the intermediate segment 340 with respect to the adjacent or neighboring intermediate segment. The range of angles of motion of an intermediate segment 340 with respect to an adjacent or neighboring intermediate segment is defined by the size and the curvature of the rotation channels 349. In the embodiment of the intermediate segment 340 shown in FIGS. 3A and 3B, the rotation post 343a is longer in size than the rotation post 343b and can be disposed in the rotation post anchor 352 of the bottom housing to secure the top housing 341 to the bottom housing 351. The intermediate segment 340 also includes an electrical receptacle 345 that is configured to receive at least an electrically conductive portion of an external device plug. The electrical receptacle 345 includes a ground receptacle 348a, a live receptacle 348b and a neutral receptacle 348c. The ground receptacle 348a can receive and electrically engage with the ground prong of an external electrical device plug, the live receptacle 348b can receive and electrically engage with the live prong of an external electrical device plug, and the neutral receptacle 348c can receive and electrically engage with the neutral prong of an external electrical device plug.
FIG. 3C is a partially exploded perspective view of an intermediate segment, according to an embodiment. The intermediate segment 340 includes a cap 347 that can function as a protective covering for the intermediate segment 340, can function as a decorative component, and can also secure the top housing 341 with the bottom housing 351 of the intermediate segment 340. The cap 347 includes two cap posts 350 that can be disposed through the cap post aperture 346 in the top housing 341 and mechanically engage with the cap post anchor 353 in the bottom housing 351 to secure the top housing 341 with the bottom housing 351. The electrical receptacle 345 also includes the electrical contact assembly 355 and the electrical contact plate assembly 357. The electrical contact assembly 355 and the electrical contact plate assembly 357 can together define the electrical connection assembly for the intermediate segment 340 and can include components such as, for example, a live connector, a neutral connector, a ground connector, etc. The electrical connection assembly can collectively define a portion of a power (or electrical signal) pathway between the intermediate segment 340 and a signal port (e.g., an external electrical power outlet), a base segment, an end segment, an adjacent inter segment, or an external device plug. The electrical connection assembly thus can be configured to receive an electrical signal from and/or send an electrical signal to a signal port, a base segment, an end segment, an adjacent intermediate segment, or an external device plug. The electrical connection assembly can also allow for maintaining electrical contact between the intermediate segment 340 and an adjacent intermediate segment through the entire range of motion of the intermediate segment 340 with respect to the adjacent intermediate segment. Similarly, the electrical connection assembly can also allow for maintaining electrical contact between the intermediate segment 340 and the base segment through the entire range of motion of the intermediate segment 340 with respect to the base segment.
FIGS. 4A and 4B are a top and bottom perspective views of an end segment, according to an embodiment. Many of the components of the end segment 460 shown in FIGS. 4A and 4B are substantially similar in form and function to the corresponding components of the intermediate segment described in FIGS. 3A-3C. The end segment 460 includes a top housing 461 and a bottom housing 471. The top housing 461 defines an aperture 462 that is configured to receive a portion of the top housing of an adjacent intermediate segment when the end segment 460 is connected to an adjacent intermediate segment (e.g., end segment 160a connected to intermediate segment 145b as seen in FIG. 1A). The end segment 460 includes a pair of rotation posts 463a and 463b that can be disposed in the pair of arcuate rotation channels defined by an adjacent intermediate segment (e.g., rotation channels 349 as shown in FIGS. 3A and 3C) to allow pivotal movement of the end segment 460 with respect to an adjacent intermediate segment. The range of angles of motion of an end segment 460 with respect to an adjacent intermediate segment is defined by the size and the curvature of the rotation channels in the intermediate segment (e.g., rotation channels 349 as shown in FIGS. 3A and 3C). In the embodiment of the end segment 460 shown in FIGS. 4A and 4B, the rotation post 463a is longer in size than the rotation post 463b and can be disposed in the rotation post anchor 472 of the bottom housing 471 to secure the top housing 461 to the bottom housing 471. Note that unlike the intermediate segments, the end segment 460 does not include any rotation channels as the end segment 460 defines the termination point of an assembly of the plug strip. Hence, only one end of the end segment is movably coupled to an intermediate segment. The end segment 460 includes a recess 468 that is configured to receive a portion of a signal port coupler (e.g., see plug strip configuration in FIG. 1G).
FIG. 4C is a partially exploded perspective view of an end segment, according to an embodiment. The end segment 460 includes a cap 469 that can function as a protective covering for the end segment 460 and can also secure the top housing 461 with the bottom housing 471 of the end segment 460. The cap 469 includes two cap posts 470 that can be disposed through the cap post aperture 467 in the top housing 461 and mechanically engage with the cap post anchor 473 in the bottom housing 471 to secure the top housing 461 with the bottom housing 471. The end segment 460 also includes an electrical receptacle 465 that is configured to receive at least an electrically conductive portion of an external device plug. The electrical receptacle 465 includes a ground receptacle 466a, a live receptacle 466b and a neutral receptacle 466c. The ground receptacle 466a can receive and electrically engage with the ground prong of an external electrical device plug, the live receptacle 466b can receive and electrically engage with the live prong of an external electrical device plug, and the neutral receptacle 466b can receive and electrically engage with the neutral prong of an external electrical device plug. The electrical receptacle 465 includes the electrical contact assembly 475 and the electrical contact plate assembly 477. Similar to the case of the intermediate segment, the electrical contact assembly 475 and the electrical contact plate assembly 477 of the end segment 460 can together define the electrical connection assembly for the end segment 460 and can include components such as, for example, a live connector, a neutral connector, a ground connector, etc. The electrical connection assembly can collectively define a portion of a power (or electrical signal) pathway between the end segment 460 and a signal port (e.g., an external electrical power outlet), a base segment, an adjacent intermediate segment, or an external device plug. The electrical connection assembly thus can be configured to receive an electrical signal from and/or send an electrical signal to a signal port, a base segment, an adjacent intermediate segment, or an external device plug. The electrical connection assembly can also allow for maintaining electrical contact between the end segment 460 and an adjacent intermediate segment through the entire range of motion of the end segment 460 with respect to the adjacent intermediate segment.
FIG. 5 is a partially exploded perspective view of a signal port coupler, according to an embodiment. The signal port coupler 525 includes a power cord 525a, a 3-prong power plug 525b that includes a ground prong 525c, a live prong 525d and a neutral prong 525e, and a cable clip 525f. The power cord 525a can be used to establish a power (or electrical signal flow) pathway between a signal port and the base segment and/or the different intermediate segments and/or the different end segments of the first assembly and the second assembly. Such a power pathway can be established when a user actuates the power button to set the plug strip to a first configuration (i.e., an “on” state). In some instances, the plug strip can include a retraction mechanism to retract at least a portion of the power cord 525a. In other instances, a portion of the power cord 525a can be passed through the base segment recess (e.g., base segment recess 122 as shown in FIG. 1) and the end segment recess (e.g., end segment recess 168a and 168b) to wrap the signal port coupler 525 around the plug strip (see FIG. 1G). As described above, in some configurations, the signal port coupler 525 can also be operably coupled to a ground fault circuit interrupter (GFCI) unit as shown in FIG. 1G. The 3-prong power plug 525b can enter and electrically engage with, for example, a three-receptacle external signal port (e.g., an external wall power outlet). The ground prong 525c can enter and electrically engage with the ground receptacle of the external signal port, the live prong 525d can enter and electrically engage with the live receptacle of the external signal port, and the neutral prong 525e can enter and electrically engage with the neutral receptacle of the external signal port. The cable clip 525f is attached to the power cord 525a and can be used to hold the power cord 525a in place when the power cord 525a is wrapped around the plug strip as shown in FIG. 1G.
FIGS. 6A-6C shows the plug strip in three different configurations, according to an embodiment. FIG. 6A shows the plug strip 600 in a first configuration where the first assembly 610 is in a first position and the second assembly 690 is in a first position and two assemblies and are substantially collinear. FIG. 6B shows the plug strip 600 in a second configuration where the first assembly 610 is in a second position which rotated and offset from the first position, and the second assembly 690 is in a second position which is also rotated and offset from the first position. In the second configuration, the first assembly 610 has rotated about the base segment 620 in a counter-clockwise direction (as indicated by the dark arrow), and the second assembly 690 has rotated about the base segment 620 in a clockwise direction (as indicated by the dark arrow).
FIG. 6C shows the plug strip 600 in a third configuration where the first assembly 610 is in a second position which is rotated and offset from the first position, and the second assembly 690 is in a second position which is also rotated and offset from the first position. In the third configuration, in the first assembly 610, the second intermediate segment 640b has rotated in a counter-clockwise direction about the first intermediate segment 640a (as shown by the arrow), and the end segment 660a has rotated in a clockwise direction about the second intermediate segment 640b (as shown by the arrow). In the third configuration, in the second assembly 690, the fourth intermediate segment 640d has rotated in a clockwise direction about the third intermediate segment 640c (as shown by the arrow), and the end segment 660b has rotated in a counter-clockwise direction about the fourth intermediate segment 640d (as shown by the arrow). The rotation of the first assembly 610 and the second assembly 690 around the base segment 120 and each of the intermediate and end segments is implemented so as to minimize gaps between parts of the plug strip and is achieved by making the base segment 620 functions as a pivot centre.
Each of the components of the plug strips discussed herein can be monolithic or a combination of parts. By way of example, with reference to FIG. 3A, rotation posts 343a and 343b and the receptacle 345 of top housing 341 can be a single piece. In other embodiments, rotation posts 343a and 343b can be separate from the top housing 341 and can be permanently or temporarily fixed to the top housing 341.

While various embodiments have been described above, it should be understood that they have been presented by way of example only, not limitation, and various changes in form and details may be made. While the plug strip is shown and described as having a certain number of intermediate and/or end segments, in some embodiments, more or fewer intermediate and/or end segments can be included. While the plug strip is shown and/or described as having certain configurations (i.e. straight, sinusoid, and circular), in some embodiments, the plug strips can have virtually any configuration based, at least, on the number of intermediate and/or end segments and/or characteristics of the intermediate and/or end segments. While the intermediate and/or end segments are shown and/or described as rotating about a single axis, in some embodiments, the intermediate and/or end segments can move relative to one another in more than one plane and/or axis, such as, for example, twisting about an axis perpendicular to the surface of a electrical receptacle, bending about an axis perpendicular to the surface of a electrical receptacle, translating along an axis, and/or combinations of such relative movements.
While shown and/described as a 120V three prong plug, the plug strip described herein can be configured for other power sources, audio, video and/or data sources, or combinations of sources, such as, for example, universal serial bus, Fire Wire, international power standards, etc. In such embodiments, the plug strip and associated intermediate and/or end segments can have more or fewer signal paths, and more or fewer associated components in accordance with the signal requirements, such as, for example, connectors, tracks, insulation members, support members, etc. Furthermore, the components shapes and characteristics of the components can be modified based on the type of outlet/plug and the number of associated components.
Other aspects of the plug strips shown and described can be modified to affect the performance and/or characteristics of the plug strip. By way of example, in some embodiments, the range of relative motion of the intermediate segments and/or end segments can be defined by the size and/or shape of the rotation channel, the size, shape, and/or number of rotation posts, and/or the type of plug/outlet. While power button 221 is shown and described as a button, in some embodiments, power button 221 can be a toggle, rocker, slider, etc. Similarly, indicator ring 223 can be any indicator, such as, for example, a uniform light source, non-uniform light source, can indicate on and/or off, etc. The plug strip can also include additional device protections, such as, for example, fuses, breakers, surge protection elements, etc.
Any portion of the apparatus and/or methods described herein may be combined in any combination, except mutually exclusive combinations. The embodiments described herein can include various combinations and/or sub-combinations of the functions, components and/or features of the different embodiments described.
