Definitions

  • This invention pertains to toothbrushes. More particularly, this invention pertains to adjustable curvature toothbrushes which comprise a flexible brush head which is adjustable to convex, concave, and straight configurations in order to conform the toothbrush to the curvature of human teeth.
  • the configuration of human teeth requires that the ideal bristle contour for toothbrushes for brushing the labial or outside surfaces of teeth be concave and that the ideal bristle contour for brushing the lingual or inside surfaces of teeth be convex.
  • Conventional toothbrushes are generally of a fixed curvature or configuration or are adjustable into different configurations. Fixed configuration toothbrushes have limited effectiveness and cannot properly clean teeth and convertible toothbrushes are generally difficult to manipulate and are unreliable.
  • United States patent no.4,712,267 issued to Cheng ,discloses a convertible toothbrush comprising an S-shaped elongated handle of shape-retaining material having curved end regions of opposite curvature, a flexible brush block containing bristles, and a means for mounting the flexible brush block on the handle for longitudinal movement along the length of the handle.
  • the curved portions of the handle bend the flexible block and bristles into a concave or convex configuration which corresponds to the curved configuration of the handle.
  • United States patent no.4,694,844 issued to Berl et al .,discloses a toothbrush comprising a handle and a hollow head supporting a plurality of tufts.
  • the hollow head further comprises an elastically deformable element which urges the tufts toward a generally straight position.
  • the pressure causes the tips of the tufts to conform to the contours of a given group of teeth because the tufts are pushed into the hollow head to varying degrees against the restoring force of the elastically deformable element.
  • United States patent no.4,691,405 issued to Reed , discloses a toothbrush comprising a handle and a base at the end of the handle consisting of two tabs containing bristles. The tabs pivot relative to the base so that the bristles mounted on the tabs deflect in order to conform to the varying tooth surfaces.
  • United States patent no.4,524,478, issued to Ross discloses a toothbrush consisting of two brush heads extending outwardly from a common elongated handle.
  • the brush heads are connected to the handle by means of curved necks extending in parallel but opposing directions and at opposite and equal angles of forty-five degrees.
  • Each brush head is designed to clean one-half of the teeth.
  • European Patent Application no. 86107868.1, to Sulit discloses a toothbrush with two brush heads, one concave and one convex.
  • the brush heads are either integral or slidable and are perpendicular at the opposite ends of their common handle.
  • the brush head with a concave-shaped bristle surface is longer while the brush head with a convex-shaped bristle surface is shorter.
  • United Kingdom patent application no. 8609437 discloses a toothbrush having a brushing surface which is set at an angle to the plane of the handle and is inclined or curved in a convex shape, as viewed in transverse cross-section.
  • the angle of the brushing surface conforms to the tooth-gum junction.
  • the present invention pertains to an adjustable curvature toothbrush which comprises (a) an elongated handle having an aperture, (b) a cam attached to the handle within the aperture by means of a cam shaft, (c) a cam follower which is engaged with, and follows, the cam, (d) a flexible brush head,(e) bristles supported by the brush head, (f) a rigid neck attached to a first end of the brush head and to an end of the handle, and (g) a flexible neck attached to a second end of the brush head and to the cam follower, whereby the curvature of the brush head can be adjusted by rotation of the cam.
  • the invention pertains to an adjustable curvature toothbrush wherein the cam and cam follower are replaced by a slidable button.
  • the invention pertains to an adjustable curvature toothbrush in the form of a compressible closed loop.
  • FIGURES 1 through 4 show a first embodiment of an adjustable curvature toothbrush which has a flexible brush head, and bristles supported by the brush head, which is adjusted by means of a cam wheel and cam follower.
