Definitions

  • the present inventionm generally relates to devices and accessories for oral care, and more particularly to an adjustably tiltable interdental toothbrush.
  • Toothbrushes of the type mentioned above are known already. Substantially these comprise an elongated handle and a wire brush, made of a metallic wire and a plurality of radial bristles, extending axially from one end of the handle.
  • the wire brush can be mounted on the handle so as to be replaceable, or the whole toothbrush may be disposable type.
  • toothbrushes of the above-mentioned type in which the wire brush can be tilted at an angle with respect to the axis of the handle such that the toothbrush may also be inserted in the hardest to reach spaces between the teeth. According to U.S. Pat. No.
  • the object of the present invention is to provide an interdental toothbrush that enables tilting of the wire brush with respect to the axis of the handle to be adjusted in a simple and safe way without the drawbacks of the known interdental toothbrushes.
  • Another object of the present invention is to provide an interdental toothbrush of the type mentioned above in which the wire brush is replaceable easily and maintains its position stably during use.
  • the wire brush is integral with a support member joined rotatingly to the handle, so that tilting of the wire brush from the axis of the handle can be adjusted and means are provided for locking the support at the desired angle with respect to the handle.
  • FIG. 1 is a side elevational view of the interdental toothbrush according to the invention.
  • FIG. 2 is a side elevational view of the interdental toothbrush of FIG. 1, rotated through 90°;
  • FIG. 3 is an enlarged partial view of the toothbrush according to the invention in correspondence with the joint, showing a cross section taken according to the arrows III-III of FIG. 1;
  • FIGS. 4 and 5 show, in plan view and side elevational view, a handle for the toothbrush according to the present invention.
  • the interdental toothbrush comprises a handle 1 culminating in a pair of ring-shape, parallel expansions 2 and 3 .
  • the circular seats 5 formed on the two expansions 2 and 3 are coaxial.
  • the toothbrush according to this invention also comprises a stem 6 , in particular truncated-conical shape in this embodiment of the invention, having at its end of larger cross-section a transversal pin 7 suitable for engaging in the seats 5 of the expansions 2 and 3 .
  • Extending axially from the lower cross-section end of the stem 6 is a conventionally shaped wire brush 8 , formed of a rod 9 from which a plurality of radial bristles 10 extend.
  • the diameter of the pin 7 is substantially equal to that of the seats 5 and the material from which the handle 1 , and more particularly the two end expansions 2 and 3 , is made, has sufficient elasticity to allow the pin 7 to access the seats 5 when moderate force is applied, establishing a rotating attachment between the handle and the stem 6 .
  • Adjustment of the tilting of the stem 6 , and accordingly of the wire brush 8 integral with it, with respect to the handle 1 is obtained due to the fact that the attachment between pin 7 and expansions 2 and 3 enables the pin 7 to be rotated in the seats 5 , when a moderate force is applied on the stem 6 .
  • the joint between handle 1 and stem 6 also comprises means for locking, the stem 6 in the chosen tilted position.
  • the locking means comprise at least a tooth 11 extending radially from the pin 7 in correspondence with at least one of the expansions 2 and 3 and a plurality of cavities 12 formed in the surface delimiting the seat 5 and angularly spaced one from the other.
  • the tooth 11 engages in one of the cavities 12
  • the stem 6 is locked at the desired angle of tilt.
  • the elastic properties of the materials that pin 7 and expansions 2 and 3 of the handle 1 are made of should be selected so as to permit passage of the tooth 11 from one cavity 12 to another when moderate force is applied on the stem 6 .
  • the wire brush 10 is provided together with the stem 6 and is therefore integral with it. Thanks to the snap-lock attachment between handle 1 and stem 6 , the toothbrush of the invention may be put together at any time and taken apart so that its dimensions are kept to a minimum and that it may easily be carried on the person either in a small bag or a purse.
  • the handle may also be manufactured in such a way that its thickness is as low as possible.
  • the handle may be built in two halves 1 a and 1 b, that may be coupled together by pressure means.
  • the two halves 1 a and 1 b are joined to one another in correspondence with the respective ends opposite the ring-shape expansions 2 and 3 which lie on a different plane, parallel to the plane of the two halves 1 a and 1 b, such that, when coupling is effected, the expansions 2 and 3 are spaced apart from one another so as to receive the pin 7 .
  • a protrusion 4 is provided, in particular in the form of a connection plug, extending from a face of one of the halves, suitable for engaging in a corresponding cavity 4 a made in the corresponding face of the other half when they are put one on top of the other, and the elasticity of the material they are made of is put to effect, enabling both a reciprocal rotation along the connection side and also a moderately forced, reversible at any time, engagement of the rib 4 in the cavity 4 a.
  • the handle may be made of rubber and the bristles of the wire brush may be subjected to antibacterial treatment.
