  • Patent number: 7089945
    Abstract: A telescoping comb for lice removal is provided for removing head lice and nits from a person's hair. The comb has a telescoping handle with serrated teeth and a pivoting handle. Resilient springs are utilized for holding the pivoting handle in an open position and holding a head portion of the telescoping handle in a closed position in the resting state. Pressure applied to the pivoting handle actuates the head portion to an open position, and upon subsequent release thereof, the head portion is spring biased back to the closed position. When the invention is used on one's hair, the teeth of the comb separate any lice from the hair where they can be safely removed.

  • Patent number: 4807652
    Abstract: A comb for removing lice and nits from the hair is formed by a base and a plurality of teeth extending from the base in substantially the same direction. The longitudinal axis of each tooth is parallel to the longitudinal axis of each other tooth. Each tooth has a polygonal cross sectional shape such as in the form of a modified triangle. The cross sectional dimensions of each tooth enlarge from the free end of each tooth toward the base so that the spacing between adjacent teeth narrows toward the base. The facing edges of adjacent teeth interact with each other to capture lice and nits therebetween. A rib is provided longitudinally along one of the faces of each tooth.
