  • a cam contact surface 1622 is located on a bottom surface of the second bristle holder 1608 adjacent to a second end 1626 thereof.
  • the cam 1614 comes into contact with the cam contact surface 1622 and drives or lifts (relative to the figure) the second end 1626 of the second bristle holder 1608 causing the second end 1626 of the second bristle holder 1608 to rock or move about the pivot 1610 in a direction away from the head portion 816 and toward the teeth of a toothbrush user (not shown).
  • the cam 1614 becomes disengaged with the cam contact surface 1622 .
  • bristles of the second bristle holder 1608 are urged against teeth of the user with a varying degree of force.
  • bristles of the second bristle holder 1608 are urged between the teeth of the user to provide a cleaning and flossing function.
  • bristles pressing against the teeth of the user urge the second bristle holder away from the users teeth and back toward the head portion 816 .
  • a flossing or deep cleaning motion is provided that is distinct from, and complimentary to, the motion provided by the first bristle holder 814 .
  • a second bristle holder 1810 is movably mounted in slots 1812 in the toothbrush head 816 and separately driven in a reciprocating or translating, transverse motion within the slots 1812 by a cam 1816 included on a driving shaft 1818 .
  • This motion is the same type of motion previously described with respect to the second bristle holder 910 shown in FIG. 7 and is also the same type of motion that the first bristle holder 814 undergoes.
  • the cam 1816 can comprise an appropriately shaped bead placed over or molded and fixedly secured to the shaft 1818 .
  • the transverse motion of the second bristle holder 1810 can be out of phase with the transverse movement of the first bristle holder 814 .
  • the cam can include one or more rectilinear, curvilinear or other kind of bend.
  • First 1822 and second 1826 cam followers depend from a bottom surface of the second bristle holder 1810 .
  • the cam followers are, for example, offset from the longitudinal axis 818 of the second bristle holder and straddle or capture the cam 1816 .
  • the motor 819 see FIG.
  • a second bristle holder 1910 is movably mounted in slots (not shown) in the toothbrush head 816 and separately driven in an reciprocating or translating, longitudinal motion, by a cam 1916 included on a driving shaft 1918 .
  • the cam 1916 can comprise a shaped bead, with an appropriate configuration, placed or molded over and firmly secured to the shaft 1918 .
  • the cam 1916 includes a reversing spiral or helical groove 1920 .
  • the spiral or helical groove extends around a circumference of the bead and spirals about a longitudinal axis of the bead. For example, the longitudinal axis coincides with the shaft 1918 .
  • a cam follower 1922 depends from a bottom surface 1923 of the second bristle holder 1910 .
  • the cam follower 1922 is slidingly received within the spiral groove 1920 .
  • a first surface 1924 of the spiral groove 1920 comes into contact with a first surface 1925 of the cam follower 1922 and drives the cam follower 1922 , and therefore, the second bristle holder 1910 away from the first bristle holder 814 along the longitudinal axis 818 of the head portion 816 .
  • the cam follower 1922 reaches an apex 1926 of the spiral groove 1920 and the first surface 1924 of the spiral groove 1920 becomes disengaged with the first cam surface 1925 .
  • a second surface 1928 of the spiral groove 1920 then comes into contact with a second surface 1930 of the cam follower 1922 and drives the cam follower 1922 , and therefore, the second bristle holder 1910 back toward the first bristle holder 814 .
  • a scrubbing motion is provided that is distinct from and complimentary to the motion provided by the first bristle holder 814 .
  • cam 1916 is eccentrically mounted on the shaft 1918 and the longitudinal axis of the bead or cam 1916 does not coincide with the shaft 1918 .
  • the cam follower 1922 is made long enough to ride on the bottom of the spiral groove 1920 , a lifting or vertical pulsing force is provided to the second bristle holder as the eccentrically mounted came is rotated by the shaft.
  • the depth of the groove is varied. The variation in depth provides lifting or vertical pulsing forces to the cam follower and therefore to the second bristle holder.
  • the spiral groove may be replaced with a groove that cycles back and forth along the longitudinal axis of the bead several times as it circles the bead. This sort of groove can be used to increase the reciprocating frequency of the second bristle holder.
  • bristles which extend in a direction substantially perpendicular to the longitudinal axis 818 and the surface (for example see 1115 of FIG. 9) of the bristle holders
  • the bristles might be arranged differently to complement or further enhance the motions of the first and/or second bristle holders.
  • some or all of the bristles might extend in a direction which forms an acute angle 2008 to a surface 2006 of the bristle holder and extends in a direction toward or away from the handle, such as shown by way of example in FIG. 18 with respect to bristles 2010 and 2014 respectively.
  • some of the bristles might extend outwardly away from head, in another direction, again forming an acute angle 2108 with respect to the surface of the bristle holder, as shown by way in FIG. 19 with respect to bristles 2110 and 2114 .
  • Elastomeric bristles or bristles of varying height might also be used, such as described in U.S. Pat. Nos. Des. 330,286 and Des. 434,563.
  • Other preferred bristle arrangements suitable for use include those arrangements described in whole or part in U.S. Pat. Nos. 6,006,394; 4,081,876; 5,046,213; 5,335,389; 5,392,483; 5,446,940; 4,894,880; and international publication no. WO 99/23910.
