  • Double suction cup holder with vacuum control valve
    Patent number: 4196882

A diametrical opening traverses the passageway and has a valve member rotatably mounted therein which has inter-communicating longitudinal and diametrical bores. When the valve is turned so that its diametrical bore communicates with the air passageway, the vacuum in the cups is spoiled releasing the holder.
