Abstract:
A power plug extender includes a bottom three-pin plug portion and a top three-pin plug receptacle portion. The top power plug receptacle portion is rotated to have a rotational offset angle between thirty degrees and sixty degrees with respect to the bottom plug portion.

BACKGROUND 
       [0001]    Many electronic devices use power adapters that are relatively bulky compared to a typical size power output. A power strip may have, for example, four, six or eight outlet plugs. However, the spacing of the outlet plugs may be such that attaching a single power adapter into one outlet plug may make one or more of the other outlet plugs unavailable because these other outlet plugs are partially covered or crowded by the single power adapter. Short extension cords, with or without pass-through, have been used to spread out the location of outlet plugs to allow for more efficient use of the outlet plugs on power strips.

     DETAILED DESCRIPTION 
       [0009]      FIG. 1  shows a power plug extender with offset pass-through  11 , a power plug extender with offset pass-through  12 , a power plug extender with offset pass-through  13 , a power plug extender with offset pass-through  14 , a power plug extender with offset pass-through  15  and a power plug extender with offset pass-through  16  plugged into a power strip  10 . 
         [0010]    Power plug extender with offset pass-through  11  includes a power plug extender section  21  having a power plug receptacle into which is plugged an adapter  31 . Power plug extender with offset pass-through  12  includes a power plug extender section  22  having a power plug receptacle into which is plugged an adapter  32 . Power plug extender with offset pass-through  13  includes a power plug extender section  23  having a power plug receptacle into which is plugged an adapter  33 . Power plug extender with offset pass-through  14  includes a power plug extender section  24  having a power plug receptacle into which is plugged an adapter  34 . Power plug extender with offset pass-through  15  includes a power plug extender section  25  having a power plug receptacle into which is plugged an adapter  35 . Power plug extender with offset pass-through  16  includes a power plug extender section  26  having a power plug receptacle into which is plugged an adapter  36 . 
         [0011]    While  FIG. 1  shows each extender having an extension cord with a power plug receptacle into which is plugged an adapter, this is only illustrative. Any of the extension cords may, instead of the shown receptacle, include for example, a power receptacle having any shape or size, or even a power strip with multiple receptacles. Alternatively, the extension cord may be directly connected to equipment requiring power to operate. 
         [0012]      FIG. 2  shows the result when power plug extender with offset pass-through  11 , power plug extender with offset pass-through  15  and power plug extender with offset pass-through  16  are removed from power strip  10 . 
         [0013]      FIG. 3  shows the result when power plug extender with offset pass-through  12 , power plug extender with offset pass-through  13  and power plug extender with offset pass-through  14  are plugged into a power strip  30 . Notice that the six power outlets in power strip  30  are ninety degrees offset from the orientation of the six power outlets in power strip  10  shown in  FIG. 2 . Despite the 90 degree rotation, power plug extender with offset pass-through  12 , power plug extender with offset pass-through  13  and power plug extender with offset pass-through  14  fit on adjacent power outlets of both power strip  10  and power strip  30 . 
         [0014]      FIG. 4  shows a top view of power plug extender with offset pass-through  11 . At the top of power plug extender is a power plug receptacle including an AC pin receptacle  41 , an AC pin receptacle  42  and a ground pin  43 . An obstruction region  44  prevents a three-pin plug from being plugged into power plug extender with offset pass-through  11  in a wrong orientation. If this were attempted, the ground pin of the three-pin plug would be obstructed by obstruction region  44 . The result is that AC pins of a three-pin plug can only be plugged into AC pin receptacle  41  and AC pin receptacle  42  in a proper orientation. 
         [0015]    While obstruction region  44  is desirable, the inclusion of obstruction region  44  as part of power plug extender with offset pass-through  11  means that without an offset, only three extender chords could be mounted on power strip  10 . The inclusion of obstruction region  44  as part of and power plug extender with pass-through would simply make the power plug extender with pass-through too long to fit six such power plug extender with pass-through onto single power strip  10 . 
         [0016]    To solve this and allow six power plug extenders with pass-throughs to be placed onto power strip  10 , the orientation of the pass through has been offset (i.e., rotated) approximately within range of 30 degrees to 60 degrees. If the orientation is offset a full ninety degrees then, for example, this would prevent six power plug extenders with pass-throughs to be placed onto power strip  30 . 
         [0017]    An offset of approximately within range of 30 degrees to 60 degrees allows allow six power plug extenders with pass-throughs to be placed onto either power strip  10  or power strip  30 . 
         [0018]      FIG. 5  shows a bottom view of power plug extender with offset pass-through  11 . Notice the position of cord  21  with respect to an AC pin  51 , an AC pin  52  and a ground pin  53 . When compared to  FIG. 4 , AC pin  51 , AC pin  52  and ground pin  53  are offset about forty-five degrees from AC pin receptacle  41 , AC pin receptacle  42  and ground pin  43 , respectively. While the offset in power plug extender with offset pass-through  11  is approximately forty-five degrees, this is only illustrative. Any offset within an approximate range of 30 degrees to 60 degrees may work. 
         [0019]      FIG. 6  is a top front left perspective view of power plug extender with offset pass-through  11  which shows the offset of AC pin  51 , AC pin  52  and ground pin  53  from AC pin receptacle  41 , AC pin receptacle  42  and ground pin  43 , respectively. 
         [0020]      FIG. 7  and  FIG. 8  shows arrangement of AC pin  51 , AC pin  52  ground pin  53 , AC pin receptacle  41 , AC pin receptacle  42  and ground pin  43  within a power plug extender with offset pass-through  11 . In this conceptual drawing, insulated portions of power plug extender with offset pass-through  11  are removed so it can be seen how within power plug extender with offset pass-through  11  AC pin  51 , AC pin  52  and ground pin  53  are respectively connected to AC pin receptacle  41 , AC pin receptacle  42  and ground pin  43 . AC pin receptacle  41  and AC pin receptacle  41  are each shown implemented by a clip. 
         [0021]    The foregoing discussion discloses and describes merely exemplary methods and implementations. As will be understood by those familiar with the art, the disclosed subject matter may be embodied in other specific forms without departing from the spirit or characteristics thereof. Accordingly, the present disclosure is intended to be illustrative, but not limiting, of the scope of the invention, which is set forth in the following claims.
