CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims priority to U.S. Provisional Application Ser. No. 61/523,240, filed Aug. 12, 2011, entitled SWIVEL SOCKET, which is incorporated herein in its entirety by this reference. 
     
    
     BACKGROUND 
       [0002]    The present invention relates to the field of trucks and trailers. 
         [0003]    Oftentimes, trailers (e.g., trailers that are hitched to, and towed behind, trucks or other vehicles) will include stop lights, turn signals, brakes, or other devices. Sometimes these various devices are to be operated via the interior of the vehicle pulling the trailer. The operation of these devices may be done electrically by coupling one or more electrical wires from the trailer to corresponding wires of the vehicle used to tow the trailer (e.g., via a plug and socket). Accordingly, by operating the corresponding devices of the vehicle (e.g., by a turn signal switch or brake pedal), a signal may be sent via one of the wires of the vehicle through the electrical coupling and to the wires of the trailer, thereby enabling the vehicle operator to effectively control the components of the trailer. 
         [0004]    When driving a vehicle towing a trailer in reverse, such as when backing the a trailer into a loading dock, the vehicle operator or truck driver may perform what may be referred to as a “jackknife” maneuver. This maneuver can cause the angle between the trailer and the vehicle towing the trailer to change, which may in turn change the angle of the abovementioned wires of the vehicle with respect to the trailer wires connected thereto. For example, if the vehicle and the trailer form a 180 degree angle when the trailer is straight with the vehicle, this angle may decrease in the aforementioned scenario. This may put stress on the connection of these wires, such as a plug and socket connection, due to the fixed position of the vehicle side of the wiring connection with respect to the vehicle, thereby causing the connection or wires to become worn, damaged, or disconnected. 
       SUMMARY 
       [0005]    By making a mounted electrical connection, such as a plug or socket, that is capable of some degree of rotation (e.g., is able to swivel about a vertical axis), stress upon the electrical connection and the electrical wiring between a vehicle and a trailer attached thereto, such as the stress that may be caused by changes in the angle of the trailer with respect to the vehicle, can be reduced or eliminated, thereby extending the effective life of the various wiring and connection components. 
         [0006]    Embodiments of the present invention provide an electrical connection capable of swiveling, or partially rotating, in one or more directions with respect to the vehicle or trailer. 
         [0007]    One embodiment of the present invention provides an apparatus for supporting an electrical connection, the apparatus including attachment means for enabling the apparatus to be mounted to a surface, a frame means rotatably coupled to the attachment means, an electrical connection coupled to the frame means, and an electrical wire coupled to the electrical connection. 
         [0008]    The apparatus may further include an electrical connection housing for housing the electrical connection and a portion of the electrical wire coupled to the frame means, and a flap hingably coupled to the electrical connection housing. 
         [0009]    The apparatus may further include a box coupled to the attachment means for housing the electrical wire coupled to the electrical connection. 
         [0010]    The box may be configured to house a circuit breaker respectively coupled to the wire. 
         [0011]    The frame means may be rotatably coupled to the attachment means with a bearing and o-ring through which the electrical wire passes coupled to a lower end of the frame means. 
         [0012]    The frame means may further be rotatably coupled to the attachment means with a clevis pin through an upper end of the frame means and through a portion of the attachment means. 
         [0013]    The attachment means may be for enabling the apparatus to be mounted to a surface of a vehicle for pulling a trailer or a surface of the trailer. 
         [0014]    The frame means may substantially enclose the electrical connection housing. 
         [0015]    The frame means may include a lower end having a first hole therethrough for allowing the electrical wire to pass, and a face substantially perpendicular to the lower end and having a second hole therethrough and coupled to the electrical connection. 
         [0016]    The frame means may further include an upper end opposite the lower end and substantially perpendicular to the face, and wherein the face is between the upper end and the lower end. 
         [0017]    The frame means may further include a back between the upper end and the lower end opposite the face, a first side between the upper end and the lower end and between the back and the face, and a second side opposite the first side and between the upper end and the lower end and between the back and the face. 
         [0018]    Accordingly, embodiments of the present invention may provide an apparatus capable of effectively reducing strain on the aforementioned wiring and wiring connection components, thereby increasing the lifetime of the relevant equipment used.

     DETAILED DESCRIPTION 
       [0024]    Referring to  FIGS. 1 and 2 , a device  10  of a first embodiment of the present invention is shown. Although  FIG. 2  is a cross sectional view of the device of the embodiment shown in  FIG. 1 , it should be noted that the positions shown in  FIGS. 1 and 2  are not identical. For example, frame means  8  of the two figures are shown to be at a different angle with respect to attachment means  2 . 
         [0025]    The electro-mechanical device  10  of the present embodiment may be used in the truck and trailer industry. The device  10  of the present embodiment may either be attached to a portion of the vehicle towing a trailer, or attached to a trailer wall via attachment means  2 , such as a bracket  2  with bolts  4  passing therethrough, although other suitable means for attachment may be used. The device  10  of the present embodiment would allow the electrical connection of electrical components of the trailer to corresponding electrical components of the vehicle via an electrical connector  6 , thereby allowing control thereof by the operator of the vehicle pulling the trailer. The electrical connector  6  is coupled to the attachment means  2  so as to allow the electrical connector  6  to swivel, rotate, or otherwise move with respect to the attachment means  2 . In the present embodiment, the electrical connector  6  is depicted as a socket  6 , although the electrical connector  6  of other embodiments may take the form of a plug or other electrical connection means. 
         [0026]    In the present embodiment, a 7-way trailer socket  6  is used as the electrical connector  6 . The socket  6  is rotatably coupled to the attachment means  2  via frame means  8 . The frame means  8  may take the form of a u-shaped bracket  8 , to which the socket  6  is affixed. Furthermore, the socket  6  may be housed within a connector housing  28 , which may serve to protect the electrical connector  6  as well as the components coupled thereto, while also enabling the socket  6  to be affixed to the swiveling frame means  8 . 
         [0027]    The frame means  8  may have a lower end  12  that is horizontal and that is coupled to the attachment means  2  via one or more swivel means  14 , such as a bearing  14   a  with an o-ring  14   b . The swivel means  14  enable rotation of the frame means  8  and socket  6  with respect to the attachment means  2 , and also allow one or more electrical wires  16  coupled to the socket  6  to pass through the swivel means  14  and the frame means  8 . In the present embodiment, the frame means  8  also have an upper end  18  rotatably coupled to the attachment means  2  by a second swivel means  20 , such as by the use of a bolt, or clevis pin  20   a,  and bearing  20   b.    
         [0028]    In the present embodiment, bolts  4  may pass through the attachment means  2  and into a trailer or vehicle wall, thereby enabling the attachment means  2  to be affixed to the trailer or vehicle. Accordingly, an angle between the trailer and the vehicle pulling the trailer may change (e.g., an angle corresponding to the rotation of the trailer about a vertical axis with respect to the vehicle) without a high degree of unwanted stress being placed on the connection of the electrical wires  16  via the socket  6 , thereby reducing the chance that a plug placed into the socket  6  would become uncoupled from the socket  6 . 
         [0029]    In the present embodiment, additional protection to the socket  6 , such as protection from weather, may be provided by a flap  22  used to cover the socket  6  when not coupled to a corresponding plug. The flap  22  may be coupled to the frame means  8  via a spring hinge  32 . 
         [0030]    Furthermore, in the present embodiment, a enclosable box-like structure  26  is coupled to the attachment means  2  underneath the lower end  12  of the frame means  8  and may be used to house the electrical wires  16  as well as circuit breakers  24  electrically connected thereto. The enclosable box-like structure  26  may also provide additional protection, such as protection from weather or the environment, to the circuit breakers  24 , the electrical wires  16 , or the electrical connections of the electrical wires  16  and the electrical connector  6 . A detachable face  34  of the enclosable box-like structure  26  is depicted as removed from the enclosable box-like structure  26  in  FIG. 1 , and is shown attached to the enclosable box-like structure  26  in  FIG. 2 . 
         [0031]    Referring to  FIG. 3 , a device  10   b  of another embodiment of the present invention is shown. The embodiment of the device  10   b  shown in  FIG. 3  is similar to the embodiment of the device  10  shown in  FIGS. 1 and 2 , however, the vertical sides and bottom of the enclosable box-like structure  26  shown in the previous embodiment are absent from the present embodiment, and the lower bearing/o-ring  14  is in a lower, horizontal portion of the attachment means  2   b  (e.g., a surface that is similar to an upper face of the enclosable box-like structure  26  of the previous embodiment). 
         [0032]    Referring to  FIG. 4 , a device  10   c  of a third embodiment of the present invention is shown. In the present embodiment, the frame means  8   b  of the device  10   c  are coupled to the attachment means  2   c  by a lower end  12   b  of the frame means  8   b,  while an upper end  18   b  of the frame means  8   b  is not coupled to the attachment means  2   c.  Additionally, the frame means  8   b  are box-shaped and partially enclose the socket  6 . The box-shaped frame means  8   b  are coupled to the lower bearing/o-ring  14  at its lower end  12   b,  and the lower bearing/o-ring  14  are coupled to the attachment means  2   c,  thereby rotatably coupling the frame means  8   b  to the attachment means  2   c . The socket  6  within the frame means  8   b  is shown in broken line. 
         [0033]    While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that features of different embodiments may be combined to form further embodiments, and that various changes in form and details may be made therein, without departing from the spirit and scope of the present invention as defined by the following claims and their equivalents.
