Electrical adapter with integral lever arms

An adapter for use with an Edison lamp holder, comprising:

• a finger grip base;
• a central core extending above from the base and having a top;
• a side electrical contact disposed on a side of the central core;
• a top electrical contact disposed at the top of the central core;
• a shell with a first outside diameter at least partially overlying the core, wherein the core translates between a top position and a bottom position within the shell, and the side and top electrical contacts protrude through to the exterior of the shell when the core is translated to the top position;
• at least two opposed, lever arms hinged at a top of the shell, wherein the lever arms swing between a horizontal position and an inclined position relative to the top, and the lever arms when in the horizontal position have a second outside diameter that is greater than the first outside diameter of the shell;
• wherein when the lever arms are moved to the horizontal position and the central core is translated to the top position within the shell, the central core engages and blocks the lever arms from swinging back to the inclined position to help retain the adapter within the Edison lamp holder, and the top and side electrical contacts engage the Edison lamp holder electrical conductors completing an electrical circuit;
• and
• wherein when the central core is translated to the bottom position within the shell, the blocked lever arms are free to swing back to the inclined position.

An adapter for use with an Edison lamp holder having electrical conductors and threads therein, comprising:

• a finger grip base;
• a central core extending above from the base and having a top;
• at least one side electrical contact disposed on a side of the central core;
• a top electrical contact disposed at the top of the central core;
• a shell with a first outside diameter at least partially overlying the core, wherein the core translates between a top position and a bottom position within the shell, and the side and top electrical contacts are exposed through to the exterior of the shell when the core is translated to the top position;
• lever arms hinged at a top of the shell, wherein the lever arms swing between a horizontal position defining a larger outside diameter and an inclined position defining a smaller outside diameter;
• means for locking disposed at the top of the shell, wherein when the lever arms swing to the horizontal position and the central core is translated to the top position within the shell, the central core engages the means for locking to hold the lever arms in the horizontal position with the lever arms wedged inside the Edison lamp holder and the top and side electrical contacts touch the Edison lamp holder electrical conductors completing an electrical circuit.
