Definitions

  • the present invention relates to toothbrushes and, in particular, it is concerned with improving cleaning capacity by providing brush head configuration directed at maximizing bristle contact with the lingual, the vestibular and the occlusal tooth surface simultaneously throughout the entire brushing process.
  • US Patent 3, 146, 478 teaches a toothbrush having a rotatable bristle configuration directed at brushing plurality of tooth surfaces simultaneously. Hoverer, the bristles do not provide the abrasive cleaning action normally provided by the bristle stiffness because the bristles are configured to rotate as they glide over the teeth.
  • US Patent 6,343,396 teaches a tooth cleaning device is which the bristles provide the required abrasive action; however, since the bristles are mounted in a single rotatable carriage, the bristles do maintain contact with the differing lingual and vestibular tooth curvatures.
  • the present invention is multi-tooth- surface brushing device for brushing lingual, vestibular, occlusal tooth surfaces simultaneously.
  • a multi-tooth-surface brushing device for brushing a plurality of tooth surfaces simultaneously includes (a) a handle having a head, and (b) at least two opposing brushes pivotably mounted on said head so that when a user's vestibular tooth surface contacts a first of said two opposing brushes, said first brush aligns with a vestibular-curvature and when a user's lingual tooth surface contacts a second of said two opposing brushes, said second brush aligns with a lingual-curvature.
  • the two opposing brushes have bristles of varying length, wherein the bristles of the first brush collectively form a substantial concave brushing surface and the bristles of the second brush collectively form a substantial convex-brushing surface.
  • the bristles are disposed at a slope in which an unattached end of the bristles is more distant from the head than an end of the bristles attached to a bristle support of each of the opposing brush heads.
  • the second brush is implemented as having a length less or equal to or less than one-half of a length of the first brush.
  • a third brush disposed in the head opposite a space in between the bristles of the opposing brushes.
  • a method for assembling a multi-tooth-surface brushing device having two opposing brushes for brushing vestibular and lingual tooth surfaces simultaneously includes: (a) providing a toothbrush handle including a head, the head having two pins rigidly attached for pivotal mounting of the two opposing brushes, each pin including at least one flange for securing each of the brushes to one of the two pins, (b) providing two brushes, each of the brushes including a bristle support having a bore of a diameter greater than a diameter of the pins, the bore including at least one annular groove disposed in a wall of the bore corresponding to the at least one flange, and (c) inserting each one of the two pins into the bore disposed in each of the brushes so that the at least one flange is seated in the at least one annular groove thereby enabling independent rotation of each of the brushes held securely on the pins.
  • FIG. 1 is an isometric bottom-view of a two-brush embodiment of a multi-surface tooth brushing device.
  • FIG. 2 is an isometric bottom-view of three-brush embodiment of a multi-surface tooth brushing device.
  • FIG. 3 is an schematic bottom-view depicting the brushing surface curvatures formed by the bristles and the relative lengths of the brushes of the multi-surface tooth brushing device.
  • FIGS. 4 and 5 are isometric bottom-views of two-brush embodiment of a multi-surface tooth brushing device depicting the independent pivotal action of each of the brushes.
  • FIGS. 6 and 7 are schematic, top partial-transparent- views of the multi- surface tooth brushing device surface cleaning device depicting the independent pivotal action of each of the brushes as the device is moved along the dental arch.
  • FIG. 8 is an isometric bottom-view of three-brush embodiment of a multi-surface tooth brushing device depicting sloping bristles.
  • FIG 9 is a schematic side-view of the device of FIG. 7 depicting bristles disposed at an angle sloping away from the toothbrush head.
  • FIG. 10 is an isometric bottom-view of a two-brush embodiment of the multi-surface tooth brushing device depicting pins on which the pivotal brushes rotate.
  • FIG. 1 1 is an isometric, partial cut-away bottom-view of a set of two opposing pivotal brushes and a bore in which the pins of FIG. 9 are disposed.
  • FIG. 12 is an isometric, exploded bottom-view of a set of two opposing pivotal brushes and corresponding pins.
  • the present invention is multi-tooth-surface brushing device with improved cleaning capacity by maximizing bristle contact with the lingual, the vestibular and the occlusal tooth surface simultaneously throughout the entire brushing process.
  • Figure 1 depicts a non-limiting, exemplary embodiment of a multi-tooth-surface brushing device respectively.
  • the brushing device generally designated 1 includes head 2, handle 3, a first pivotally mounted brush 4 and associated bristles 6, second pivotally mounted brush 5 and associated bristles 8.
  • the three-brush embodiment depicted in Figure 1 further includes third brush 9 statically mounted on head 2 opposite the space defined between bristles 6 and 8.
  • Figure 2 depicts an analogous two-brush embodiment.
  • the three-brush embodiment enables global scrubbing in which each of the vestibular, the lingual, and the occlusal tooth surfaces are cleaned simultaneously.
  • Figure 3 depicts two brushing surface geometries; brushing surfaces 10 and 11 are both formed from bristles of varying length.
  • Bristles 6 vary in length to collectively form a curvature approximating the vestibular curvature 12 of the dental arch and bristles 8 vary in length to collectively form a curvature approximating the lingual curvature 13 of the dental arch as shown in Figures 6 and 7.
  • Figure 3 also depicts an additional feature of the present invention in which brush 5 has a length less than the length of brush 4
  • the reduced length of brush 5 advantageously enables a user to brush difficult-to-access molars.
  • the shorter brush provides for a brushing surface having a curvature more closely fitting the lingual-tooth-surface curvature.
  • the brush length of brush 5 is half or less than half of the brush length of brush 4; however, it should be appreciated that any embodiment in which the length of one brush is less than the opposing brushes is included within the scope of the present intention.
  • Figures 4 and 5 illustrate the independent, bi-directional rotation of brushes 4 and 5.
  • brush 4 pivots into best-fit alignment with vestibular tooth surface 12 and similarly, when the brushing surface of brush 5 contacts the lingual tooth 13 surface, brush 4 independently pivots into a best-fit alignment with lingual tooth surface 13 as shown in 6-7
  • brushes 4 and 5 continue to pivot independently and simultaneously into a best fit alignment with the changing vestibular and lingual tooth surface curvatures, thereby maximizing tooth scrubbing.
  • embodiments having three, four or any plurality of pivotal brushes are included in the scope of the present application as well as brushes having bristle lengths of varying lengths collectively forming any type of curved brushing.
  • Figures 8 and 9 depict an additional feature directed at improving cleaning effectiveness-
  • ideal scrubbing is accomplished when the bristles contact the teeth at an angle of about 45 degrees relative to the substantially vertical plane defined by the teeth.
  • bristles 6 and 8 are perpendicularly fastened to bristle support 18.
  • Bristle support 18 has a sloping surface to which the bristles are fastened so that bristles 6 and 8 are disposed at about a 45 degree angle relative to head 2 in a non-limiting, exemplary implementation.
  • a variant embodiment having bristles fastened to a non-sloping bristle support (not shown) is also included in the scope of the present invention.
  • an embodiment in which bristles are disposed in a non-parallel manner relative to head 2 is included within the scope of the present invention.
  • bristles 8 and 6 vary in length as a function of their distance from head 2 to ensure that all of the sloping bristles contact the tooth surface.
  • Figures 10 and 11 depict a non-limiting pivot arrangement of brushes 4 and 5 on pins 21 rigidly attached to head 2.
  • Brushes 4 and 5 each have an upwards bore 23 extending into the height of brashes 4 and 5.
  • the bore diameter is slightly larger than the pin diameter to ensure brush rotation on pins 21.
  • Each of brushes 4 and 5 is held permanently on pins 21 by way of a flange 25 disposed on each pin 21 that pivotally engages annular groove 24 disposed in the inner surface of bore 23. It should be noted that a configuration having a plurality of flanges and corresponding plurality of annular grooves is included within the scope of the present invention.
  • Brush rotation is limited by way of plurality of small protrusions 22 protruding upwardly from head 2 so as to block brush rotation.
  • each brush has no more than 180 degrees of freedom rotation.
  • angular brush rotation is regulated by a flange and groove arrangement as is known to those skilled in the art.
  • the brushing device is assembled by sliding brushes 4 and 5 over pins 21 until flanges 24 are seated in the corresponding annular groves disposed in the bore wall.
  • the handle is manufactured from hard plastic formed by injection molding whereas the bristles are manufactured from nylon and fastened to the brush head as is known to those skilled in the art. It should be noted that any polymeric material and other manufacturing process typically used in the art are included in the scope of the present invention.
