Definitions

  • the invention includes a toothbrush comprising, in combination, elongated handle means; a pair of oblong brush carrier means pivotally mounted in the area of one end of said handle means for turning movement relative thereto between a first position in which said oblong brush carrier means extend from said area alongside each other in longitudinal direction of said handle means, and a second position in which said oblong brush carrier means extend from said area in directions opposite to each other and transversely of said longitudinal direction of said handle means, each of said brush carrier means being equipped with a plurality of bristles projecting therefrom in a direction transverse of the plane of rotation of said brush carrier means; and control means for moving said brush carrier means between said first and second positions thereof.
  • the invention includes a toothbrush comprising, in combination, elon ated handle means; and oblong brush carrier means mounted in the area of one end of said handle means and extending transversely of the longitudinal direction of said handle means, said brush carrier means being curved in a plane transverse of said longitudinal direction of said handle means and being equipped with a plurality of bristles projecting therefrom substantially in the direction of said plane.
  • FIG. 1 is a plan view of a toothbrush according to the invention, in a first position of the movable parts thereof;
  • FIG. 2 is a lateral view of the toothbrush according to FIG. 1;
  • FIG. 3 is an end view of the brush illustrated by FIGS. 1 and 2;

  • FIG. 8 is a plan view of the slide member of the toothbrush according to FIGS. 1-5;
  • FIG. 9 is a lateral view of the slide member according to FIG. 8.
  • FIG. 10 is a diagrammatic illustration at a larger scale of the end portion of the toothbrush according to the invention.
  • one embodiment of the invention is a toothbrush which comprises an elongated handle a which carries at one end two brush carriers b and of oblong shape which extend from the end of the handle a in opposite directions transversely of the longitudinal direction of the handle a and which are curved as illustrated by FIG. 3 in a plane also transverse of the longitudinal direction of the handle a.
  • the bristles b extend from the concave surfaces of the brush carrier members [2 and b substantially in the plane of said curvature. Consequently, the entire set of bristles b in the curved arrangement shown by FIG.
  • the brush carrier members b and b are mounted adjustably on the handle a so that their position relative to the handle can be changed for the purpose of using, in one position, the brush in the manner described above for cleaning the outside of the teeth, particularly in the front portion of the mouth, and for using the brush, in a second position, for cleaning particularly the inside of the teeth.
  • the illustrated embodiment comprises a pair of oblong brush carrier members b and b which are pivoted at the end of the handle a.
  • each of the brush carrier members b and 12 is provided with a pivot pin composed of a portion f or f respectively, of comparatively larger diameter and an extension f or f respectively, of smaller diameter, the last mentioned portion fitting into corresponding hearing holes a l and a respectively, provided in the handle member a.
  • the above mentioned pivot pins are held in place in the bearing holes by some suitable means e.g. by a small plate hi or f respectively, attached to the outer end of the pivot pin.
  • the brush carrier members b and being thus pivot ally mounted near the end of the handle a can be moved or turned between two positions, namely between a first position as illustrated by FIGS. 4 and 5 in which the two brush carrier members b and b extend alongside each other in the longitudinal direction of the handle a, and a second position illustrated by FIGS. 1-3 in which the two brush carrier members extend from the end of the handle a in opposite direction to each other transversely of the longitudinal direction of the handle a.
  • control means are provided which may consist for example by a slide member 0 as illustrated separately by FIGS. 8 and 9 which is arranged for member 1.
  • One possibility is to provide one of these members with a projecting portion and the other member with a corresponding slot, groove or'recess in which the projecting portion may slide.

  • each of the brush carrier members bi and b is also pro- 7 rier member.
  • the slot or groove k is fitted over the above mentioned pin I1 of the slide member c while the slot k is similarly fitted over the pin k It will be understood that if the slide 0 is moved a certain distance in the lengthwise direction of the handlea, the'pins h and I1 will move the respective brush carrier members,
  • FIG. 2 shows the slide member c-moved relative to the handle a enough for, causing the brush carrier members b and b to assume the above mentioned second position as illustrated in FIGS. 1-3.
  • the handle member a may be provided with a small hole c' and the slide memberwith aslot c'.
  • a rivet c" or the likeplaced through'the slot c and thehole c' and remaining slidable in the slot c may be used for achieving this result.
  • the small gap existing between the inner ends of the brush carrier members b and [2 as shown in the second position illustrated by FIGSJ and 3 is in no way deterimentalfor the cleaning effect because to, carrying out the most effective and suitable operation
  • the user of the toothbrush 7 can easily control the desired position of the brush car rier members because while holding the toothbrush in his hands .he can easily shift withhisfingers the slide member 0 lengthwise relative to the handle member .a.
