  • Patent number: 6461074
    Abstract: A locking mechanism for a telescopically adjustable extension pole is disclosed. The locking mechanism includes a collar member and a locking trigger mechanism preferably comprising a bottom trigger member and a top trigger member having a locking pin therein. The top trigger member grippingly engages the collar member which is attached to the outer sleeve of the pole. By depressing the bottom trigger member, the top trigger member moves laterally outwardly retracting the locking pin from an aperture in the inner sleeve permitting the length of the extension pole to be telescopically adjusted. By releasing the bottom trigger member, the top trigger member moves laterally inwardly causing the locking pin to be received within an aperture in the inner sleeve so as to interlock the inner sleeve within the outer sleeve at the approximate desired length of the extension pole.

  • Patent number: 6367114
    Abstract: A paint brush which incorporates a mixture of natural bristles and synthetic crinkle filaments is disclosed. The natural bristle can be hog bristle, or the like, and the synthetic crinkle filaments can be formed from a polyester resin and include a plurality of waves or crimps along their length. The paint brush retains its shape through use and the bristles do not become “floppy” when used with water-based paint. In addition, the paint brush provides excellent paint “pick-up” and release properties and has superior surface coverage capabilities.
