Abstract
A system to facilitate installation of a small fan into a ceiling light fixture. A male electrical plug with electrical wire is installed upon the top of a rigid structure. An electrical adapter is inserted into the light fixture's socket in lieu of a light bulb. The conductive prongs of the plug are inserted into a receptacle of the adapter. A leverage arm is created at the bottom of the rigid structure and extends opposite and beyond the vertical centerline of the apparatus to a position where a higher percentage of the weight of the combined appliance and fan is distributed to the side of the centerline opposite the plug putting downward pressure on the outer end of the leverage arm configuration which, in turn, causes the top portion of the apparatus to rotate toward the centerline and to push the prongs inward.
