  • Replacement apparatus for fluorescent bulbs
    Patent number: 5330243
    Abstract: A bulb grasping unit for an elongated cylindrical fluorescent bulb is rigidly mounted on an elongated handle to facilitate replacement of fluorescent bulbs supported by two prongs on the bulb ends en resiliently mounted tubular contacts in out of reach fixtures. The bulb grasping unit is integrally formed from plastic and defines a generally semi-cylindrical recess which is resiliently radially expandable to snap into engagement with the fluorescent bulb. When one bulb prong is inserted in one tubular contact, upward movement of the other end of the bulb by the bulb grasping unit engages a cam on the end of the bulb grasping unit with a cam surface on the fixture to axially shift the other prong into alignment with the other tubular contact.
