System and method for multi-positional power supply adaptor
View Patent ↗A portable (travel) charger or power adaptor ( 10 ) can minimize the protrusion from a wall when used as a wall mounted charger and can further maximize the number of power adaptors that can be (safely) plugged into a standard AC strip. The power adaptor can include a housing ( 12 ) containing a power transformer and a pair of pivoting prongs ( 13 and 15 ) forming a plug ( 14 ) arranged to be substantially near a top portion of the housing. The pair of pivoting prongs in a first position or horizontal position can make the adaptor suitable or configured for coupling to an AC wall outlet receptacle and in a second position or vertical position can make the adaptor suitable or configured for placement in an AC strip receptacle ( 22 ) of a standard power strip ( 20 ).
1. A power supply adaptor, comprising:
a housing containing a power transformer;
a pair of pivoting prongs arranged to be substantially near a top portion of the housing;
wherein the pair of pivoting prongs in a first position makes the power supply adaptor configured for coupling to an alternating current wall outlet receptacle and the pair of pivoting prongs in a second position substantially perpendicular to the first position makes the power supply adaptor configured for placement in an alternating current strip receptacle;
wherein the power supply adaptor further comprises a moveable cover coupled to the housing that covers the pair of pivoting prongs in the second position when the moveable cover is in an extended position and the pair of pivoting prongs in the second position become exposed when the moveable cover is placed in a compressed position.
2. The power supply adaptor of claim 1 , wherein the pair of pivoting prongs in the first position protrude outside the moveable cover.
3. The power supply adaptor of claim 1 , wherein the power supply further comprises an internal spring mechanism coupled to the moveable cover that biases the moveable cover in the extended position.
4. The power supply adaptor of claim 1 , wherein the power supply adaptor is an alternating current adaptor.
5. The power supply of claim 1 , wherein the process of placing the pair of pivoting prongs when in the second position into an alternating current strip receptacle causes the moveable cover to move into a compressed position and a removal from the alternating current strip receptacle causes the moveable cover to return to the extended position.
6. A multi-positional power supply adaptor, comprising:
a housing containing a power transformer;
a pair of prongs arranged to be substantially near a top portion of the housing;
wherein the pair of prongs in a horizontal position makes the power supply adaptor configured for coupling to an alternating current wall outlet receptacle and the pair of prongs in a vertical position makes the power supply adaptor configured for placement in an alternating current strip receptacle;
wherein the power supply adaptor further comprises a moveable cover coupled to the housing that covers the pair of pivoting prongs in the vertical position when the moveable cover is in an extended position and the pair of pivoting prongs in the vertical position become exposed when the moveable cover is place in a compressed position.
7. The power supply adaptor of claim 6 , wherein the pair of pivoting prongs in the horizontal position protrude outside the moveable cover.
8. The power supply adaptor of claim 6 , wherein the power supply further comprises an internal spring mechanism coupled to the moveable cover that biases the moveable cover in the extended position.
9. The power supply adaptor of claim 6 , wherein the power supply adaptor is an alternating current adaptor.
10. The power supply of claim 6 , wherein the process of placing the pair of pivoting prongs when in the vertical position into an alternating current strip receptacle causes the moveable cover to move into a compressed position and a removal from the alternating current strip receptacle causes the moveable cover to return to the extended position.
11. A method of selectively altering a power adaptor for use in conjunction with at least one among an alternating current wall outlet receptacle and an alternating current strip outlet receptacle, comprising the steps of:
selectively placing a pair of pivoting prongs in a first position configured for coupling to the alternating current wall outlet receptacle;
selectively placing a pair of pivoting prongs in a second position substantially perpendicular to the first position configured for placement in an alternating current strip receptacle;
covering the pair of pivoting prongs when in the second position with a moveable cover when the moveable cover is in an extended position; and
exposing the pair of pivoting prongs in the second position when the moveable cover is placed in a compressed position.
12. The method of claim 11 , wherein the method further comprises the step of exposing the pair of pivoting prongs when in the first position when the moveable cover is placed in an extended position.
13. The method of claim 11 , wherein the process of placing the pair of pivoting prongs when in the second position into an alternating current strip receptacle causes the moveable cover to move into a compressed position and a removal from the alternating current strip receptacle causes the moveable cover to return to the extended position.
