  • Patent number: 7334503
    Abstract: A light bulb changing tool is adapted for use with a conventional vacuum cleaner whose suction nozzle is of an indeterminate diameter. In some embodiments, the light bulb changing tool includes a rotational slip joint that enables the tool to be rotated while the vacuum cleaner is stationary. In some cases, the tool includes a torque-limiting coupling that allows the tool to exert greater loosening torque than tightening torque, thereby avoiding over tightening of the bulb and ensuring that the bulb can later be removed without breakage.
