Definitions

  • This invention relates to a resilient brush for cleaning or polishing of a surface of an object.
  • the brush is pressed down to the extent that the bristles are excessively bent, some of the bristles may be easily broken or worn and the friction may be concentrated on the protrusion, not the recess, of the irregularity, resulting in abrasion of only the protrusion.
  • the prior toothbrush used in a human tooth having a curved surface rather than a flat surface can not accomplish uniform polishing and cleaning of the tooth's surface and instead be easily worn.
  • a resilient brush for cleaning or polishing of a surface of an object, the brush comprising a body having a plurality of blind holes formed therein in a given pattern; a cover formed with guide holes corresponding in number and position to said holes of said body, and bonded to the upper surface of said body; tufts each comprising a packet of bristles extending through each of said guide holes of said cover and having a support piece bonded to their lower ends, the support piece being movably received in each of said holes of said body; and resilient means disposed one below each support pieces within said holes of said body to normally bias upwardly said support pieces having said tufts of the bristles bonded thereto.
  • a brush has tufts each comprising a packet of bristles made of any of various materials, for example, natural animal hairs, synthetic resin filaments, metal wires, etc., and arranged in an adequate pattern, depending upon the uses of the brush.
  • Fig. 1 shows a perspective view, partly in cut way, of a typical brush among the brushes of various kinds and types provided according to the present invention.
  • reference numberal 1 designates the tufts of the bristles.
  • Each of the tufts 1 is bonded at its lower end to a generally disk-shaped support piece 2.
  • the brush comprises a body 3 having a plurality of upwardly open blind holes 4 formed therein in a given pattern.
  • the support pieces 2 each having the tuft of the bristles bonded at its lower end to a generally disk-shaped support piece 2.
  • the brush compises a body 3 having a plurality of upwardly open blind holes 4 formed therein in a given pattern.
  • the support pieces 2 each having the tuft of the bristles bonded thereto are movably received one within each the holes 4 of the body 3, with the bristles extending upwardly. At this time, before the support pieces 2 are disposed within the holes 4, springs 5 for upwardly biasing the support pieces are firstly disposed one within each the holes.
  • a cover 7 having a plurality of guide holes 6 formed therein to correspond in number and position of the holes 4 of the body 3 is secured to the inlet sides of the holes, i.e., the upper side of the body.
  • Each of the guide holes 6 has a diameter less than the diameter of the support piece 2.
  • each of the tufts of the bristles extends outwardly through each of the guide holes 6 formed in the cover 7, with the support piece 2 movably positioned within the hole 4 of the body 3.
  • the tuft 1 comprising a packet of the bristles may be moved upward and downward in complicance with a state of the surface with which its tip is brought into contact, while being subjected to the elastic force exerted therupon by the spring 5.
  • any of various types of springs other than the coil spring can be used for the same purpose.
  • spring modulus of the spring is selected to have an adequate value according to the uses of the brush (for example, whether it will be used in cleaning or heavy polishing operating) and the materials of the bristles.
  • the basic construction of the brush according to this embodiment is sustantially the same as that of the previous embodiment with the exception the differently from the construction shown in Fig. 1 in which after disposition of the springs 5 and the tufts 1 of the bristles within the holes 4 of the body 3, the cover 7 is secured to the upper side of the body 3, the brush of this embodiment comprises a body 3 having a plurality of downwardly open cylindrical holes 4a formed therein, and a cover 7a attached to the lower surface of the body 3 to cover 7a the cylindrical holes 4a of the body 3 with the tufts 1 and the springs 5 disposed within the cylindrical holes 4a.
  • each of the holes has a through-hole which is formed centrally of the bottom thereof and through which the tuft of the bristles extends outwardly.
  • the through-hole has a diameter less than the diameter of the support piece.
  • the brush can carry out the uniform brushing operation while exerting a constant pressure upon the friction surface, regardless of the state of the irregular surface. Therefore, the uniform cleaning or polishing of the friction surface can be accomplished without abrasion of some of the bristles, or excessive abrasion of the specific portion of the rugged surface.
  • the toothbrush to which the present invention is applied may contribute to health of the tooth greatly important to a human being, and has enhanced brushing efficiency, resulting in reduction of time taking to accomplish a satisfactory brushing effect, and prolongation of the service life to the toothbrush.
  • the present invention can be extensively applied to various kinds of brushes regardless of the materials of the bristles and the uses of the brush, whereby polishing or cleaning of a cubic structure having a very rugged surface may also be satisfactorily accomplished.
  • polishing or cleaning of a cubic structure having a very rugged surface may also be satisfactorily accomplished.
