Abstract
This invention relates to toothbrushes of the kind in which a head having bristles projecting from at least one side thereof is articulated to an adjacent end of a handle for adjustment of the head with respect to the handle. The articulating means of the invention include a pair of projections integral with either the head or the handle and journalled in cooperating sockets in the other part, and means are provided for resisting relative turning movement between the head and handle, whereby the head and handle are adapted to be set in a desired position relatively to one another without being locked in said position.
