Definitions

  • This,invention relates to a toothbrush structure.
  • Said film provides basic support for the growth of a bacterial blotch, which undoubtedly favors the development of those substances which are the cause of decay erosion and destructive and regressive processes affecting the tooth supporting tissues, and specifically the bone.
  • This danger is mainly the outcome of the impossibility to spread and balance the pressure from the whole active face of the brush, whether the latter is provided with natural or artificial bristles.
  • the regions of the tooth which are more liable to such damage are those of the canines and premolars, which are located at a smaller radius arc and are subjected to greater and more uneven friction.
  • the ta'sk of the invention is that of overoom- ing the aforesaid drawbacks, by providing a toothbrush which allows a degree of freedom in the bristle-carrying head seating, such as to make it virtually independent of the handle, and accordingly free to dispose itself parallel to the area to be cleaned, thus achieving a balanced spreading of the frictional force.
  • a toothbrush structure comprising a handle element and bristle-carrying head, characterized in that said bristle-carrying head is mounted to rock with respect to said handle element.
  • the toothbrush structure comprises a handle element 1 which is terminated at one end with a yoke element 2 carrying, offset with respect to its own axis, a pin 3, whereto a bristle-carrying head, generally indicated at 7, is articulated for a rocking movement.
  • the bristle-carrying head 7 has two side fins 4 which carry a small bridge or middle part 5, wherefrom the bristles 6 extend.
  • the cited fins 4 are arranged such that they are positioned externally of the yoke part 2 of the handle element 1.
  • the bristle-carrying head 7 is free to orient itself, within limits, such as to always lay in a parallel plane to the reaction surface which,in this specific case, is comprised of the para-elliptical surface of the tooth arches.
  • the invention achieves its objects, and in particular that by swingably coupling the bristle-carrying head and handle a uniform distribution of the brushing forces can be obtained on account of-the bristle-carrying head adjusting itself automatically.
  • the bristle-carrying head may have a different color than the handle, thus allowing all of the chromatic and shape combinations which are judged to be fitting.
  • the yoke element and handle element 1 may be modified, and the same may apply to the bristle-carrying head owing to the conformation of the bristle-carrying head, seeing that the invention inspiring concept is based on the fact of allowing the free oscillation-of the area where the bristles are provided with respect to the handle.
  • the materials employed, as well as the dimensions and contingent shapes may be any ones depending on requirements.
