Toothbrush

A toothbrush comprises, normally as a single piece,: an elongated handle 10; a head 20 with bristles 40; and a flexible neck 30 joining the handle to the head. The neck comprises a pair of front and rear spaced longitudinal beams 31,32 which have their ends joined, respectively, to the head and handle by localised bending means 34 which allow the beams to operate as parallelogram articulation arms when the head is displaced transversally of the handle, in a plane containing the axis of the handle and parallel to the axis of the bristles, from an inoperative rest position, Fig. 1, to operative positions. The brush may be provided with a shock absorbing means 50, acting against the neck 30 and preferably by means of an elastic element fitted into the aperture 33, in such a manner as to be elastically deformed when the head is displaced.
