  • Patent number: 6546596
    Abstract: An extension pole for tools provides nearly universal attachment of a wide variety of different tool heads or components, for painting, cleaning, and other tasks which may require a long reach to access otherwise inaccessible areas. The present extension essentially comprises a tubular base or handle component and a tubular extension component. The extension tube telescopes within the base tube and may be locked at the desired extended length by a pull release pin which extends through a selected one of several holes in a keyway in the extension tube. The distal end of the handle tube includes a folded down tab which engages the extension tube keyway, to preclude axial rotation of the extension tube within the base tube. The distal end of the extension tube includes a threaded attachment, preferably having an Acme threaded configuration to provide nearly universal attachment of a wide variety of devices.
