  • Bulb changer attachment system
    Patent number: 8783136
    Abstract: A bulb changer attachment system comprising: a conical suction light bulb receiver having a distal end and a proximal end; a base having a top portion and a bottom portion; an adapter; and a vacuum hose attachment providing vacuum communication with at least one vacuum. The conical suction light bulb receiver is connected to the top portion of the base while the bottom portion of the base is connectable to the vacuum hose attachment via the adapter. A light bulb is received by the conical suction light bulb receiver such that an apex of the light bulb is suction-contacted by the proximal end of the conical suction light bulb receiver and an outer periphery is suction-contacted via the distal end of the conical suction light bulb receiver. The conical suction light bulb receiver is removeably-coupleable to the light bulb enabling a user to remotely access the light bulb for changing.
