Definitions

  • THE PRESENT INVENTION relates to a device for cleaning teeth.
  • the element comprises a defoimable core having, on one side, two spaced apart upwardly directed bristles and carrying, on the other side, downwardly directed bristles.
  • the tips of each set of bristles are configured to form a "valley" and, in use, selected teeth from the upper jaw are placed in the upper valley and selected teeth from the lower jaw are placed in the lower valley and the jaw is closed, thus compressing the central core and causing the bristles defining each valley to converge so that the tips of the bristles engage the sides of the teeth, thus cleaning the teeth.
  • the present invention seeks to provide an alternative element for cleaning teeth.
  • a device for cleaning teeth comprising a defoimable resilient core, the core ca ⁇ ying two spaced apart upstanding supports, so that the core and the supports define a valley, the valley containing an insert of cleaning material, the arrangement being such that a tooth brought into engagement with the cleaning insert, when compressing the device against an opposed tooth, will cause the core to deform, thus moving the supports to bring the cleaning insert into contact with the sides of the tooth.
  • the device is of syrnmetrical form having lower supports defining an opposed valley containing a respective cleaning insert.
  • the core is a simple hollow core.
  • the core may be of substantially diamond cross-section comprising four plates h ngedly inter-connected, two supports being carried by the upper plates and two supports being carried by the lower plates.
  • the core may be of octagonal lozenge section having two upper plates each carrying a respective support, and two lower plates each ca ⁇ ying a respective support.
  • the core may be of hollow substantially circular section, the core supporting two generally upwardly directed supports, and two generally downwardly directed supports.
  • the core comprises a central membrane, each end of the membrane being associated with an upwardly and inwardly directed arm teiminating with a plate, the plates extending substantially parallel with the membrane above the membrane, and also being associated with two downwardly and inwardly directed arms each ca ⁇ ying a plate, the plates extending substantially horizontal with the membrane and being located beneath the membrane, each of the plates ca ⁇ ying a respective support, the plates over-lapping each other and being slidable relative to each other.
  • the cleaning insert is an insert having abrasive properties.
  • the cleaning insert is foimed of packed cotton.
  • the cleaning insert is impregnated with a dentifrice or other cleaning agent.
  • the invention also relates to a device as described above in combination with a handle adapted to engage the defoimable core.

  • FIGURE 7 is a figure illustrating the embodiment of Figure 6 in use
  • FIGURE 8 is a view of another alternative embodiment of the invention.
  • FIGURE 9 is a view illustrating the embodiment of Figure 8 in use.
  • a device 1 for cleaning teeth comprises a defoimable core 2, the defoimable core ca ⁇ ying, in its upper region, two spaced apart generally upwardly directed substantially rigid supports 3, 4 which, together with the core, define an upwardly open valley 4.
  • the core 2 cairies two spaced apart depending substantially rigid supports 6, 7, which depend from the lower part of the core, and which define a downwardly open valley 8.
  • a generally "U"-shaped insert 9 of tooth cleaning material Received within the upwardly open valley 5 is a generally "U"-shaped insert 9 of tooth cleaning material.
  • the insert may be made of a foam material, or may be made of fibrous material such as, for example, packed cotton.
  • the insert preferably has slightly abrasive properties.
  • the insert may be impregnated with a cleaning agent, such as a dentifrice.
  • a co ⁇ esponding insert 10, of inverted "U"-shaped form is received in the downwai'dly open valley 8.
  • the inserts may be held in place with an adhesive or with one or more tongs formed on the core or supports that engage and retain the inserts.
  • the flexible core 2 in this embodiment of the invention, comprises a horizontally extending substantially rigid membrane 11.
  • One end of the membrane supports an upwaidly and inwardly directed arm 12, which terminates with a horizontally extending plate 13 which is parallel with but spaced from the membrane 11.
  • the aim 12 is pivotally or hingedly mounted on the membrane 11.
  • the plate 13 is pivotally or hingedly comiected to the free edge of the aim 12.
  • the other edge of the membrane 11 pivotally or hingedly supports an upwaidly and inwardly directed arm 14 which pivotally or hingedly cairies a horizontally extending plate 15 which again extends substantially parallel with the membrane 11.
  • the plate 15 slightly overlaps the plate 13.
  • the defoimable core 2 is substantially symmetrical about the plane of the membrane 11, and thus beneath the membrane 11 there are equivalent fingers and plates 12, 14, 13, 15. These fingers and plates will therefore not be re- described in detail.
  • the support 3 is securely mounted on the aim 12 and part of the plate 13.
  • the support 4 is mounted on the aim 14 and part of the plate 15.
  • the supports 6 and 7 are mounted in a similar way on the under-side of the membrane 11.
  • the flexible core 2 may be mounted on an appropriate handle 20
  • the handle 20 is provided with two parallel prongs 21, 22.
  • the prong 21 is connected to the upper plate 15, and the prong 22 is connected to the lower plate 15.
  • the flexible core 2 is located in position between opposed teeth, such as opposed molars 30, 31.
  • the upper molar 30 is introduced to the interior of the generally "U"-shaped insert 9 present within the valley 5, and similarly the lower molar 31 is introduced to the interior of the inverted "U"-shaped insert 10 present in the lower valley 8.
  • the molars may then be moved towards each other thus compressing the core 2.
  • the plates 15 and 13 over-ride each other, and thus the aims 12 and 14 begin to pivot about their points of connection with the membrane 11.
  • the supports 3 and 4 thus begin to move pivotally inwardly towards the molars 30, 31.
  • Figure 3B shows a subsequent stage when the molars are closer together, thus causing the supports 3 and 4 to pivot closer towards the molars.
  • Figure 3D shows a final situation where the molars have been moved towards each other to such an extent that the parts of the inserts 9 and 10 initially located adjacent the sides of the molars have actually been brought into contact with the molars. As the molars continue to move, the inserts 9 and 10 exert a cleaning effect on the molars. The molars 30, 31 may then be moved apart, to the position shown in Figure 3E which is, of course, the same as the start position shown in Figure 3A. The procedure may then be repeated until a sufficient cleaning of the molars has been effected.
  • Figure 4 shows the device 1 when used with incisor teeth 32, 33.
  • the start condition, as shown in Figure 4A, is equivalent to that shown in Figure 3A.
  • the incisors 32, 33 are moved towards each other, with a deformation of the core 2, until incisors occupy the position shown in Figure 4B, with the points of the incisors 32, 33, almost touching each other.
  • the core 2 has been very substantially defoimed, so that the supports 3, 4, 6 and 7 have been moved to such a position that the cleaning inserts 9 and 10 are brought into contact with the exterior of the incisors 32, 33.
  • the jaws may then be drawn apart rerarning the incisors to the position as shown in Figure 4C, which is equivalent to the position shown in Figure 4A.
  • FIG. 5 illustrates a modified embodiment in which the core is a hollow element of generally "diamond" form having two upper plates 40, 41 which are inclined relative to each other, and interconnected by a pivoting hinge 42, and two lower inverted inclined plates 43, 44 which are again inter-connected by a pivoting hinge 45, the upper plates being connected to the lower plates by hinging connections 46, 47.
  • the supports 3 and 4 are connected to the upper plates 40, 41 and supports 6 and 7 are connected to the lower plates 43, 44.
  • Cleaning inserts 9 and 10 are provided as in the previously described embodiment.
  • an incisor 30 can be brought towards the upper cleaning insert 9 and an incisor 31 can be brought towards the lower cleaning insert 10.
  • the central core is slightly compressed, with the angle of inclination between the plates 40, 41 increasing, and similarly with the angle of inclination between the plates 43, 44 increasing, thus bringing the free ends of the supports 3, 4 and the free ends of the supports 6 and 7 closer towards the incisors 30, 31. This is the position shown in Figure 5B.
  • Figure 6 illustrates a further core that may be used in an embodiment of the invention, and an associated handle.
  • the core 50 does not have a diamond-shaped section as shown in Figure 5, but instead has a lozenge-shaped octagonal section. This section includes four plates which co ⁇ espond with the four plates of the above-described core of diamond foim.
  • a handle 51 may be provided for use with the core as shown in Figure 6. Inserts 9 and 10 will be provided for use with the core of Figure 50.
  • Figure 7 illustrates the configuration of the core before being defoimed by opposed teeth at Figure 7A, and shows the shape of the core at Figure 7B after defoimation.
  • Figure 8 illustrates yet a further embodiment of the invention in which the centi'al part of the core is of circular section, the core carrying supports 3, 4, 6 and 7 of the type discussed above.
  • Figure 9A illustrates the core in an initial un-defoimed condition with the supports 3, 4, 6 and 7 spaced apart and
  • Figure 9B illustrates the core in the position that it will adopt when defoimed between opposed teeth.
  • the supports have moved generally pivotally inwardly, and thus inserts, such as the inserts 9 and 10 as described above, when mounted on the core would be moved into cleaning engagement with the teeth acting to defoim the core.
  • the core cairies four supports defhiing two opposed valleys, each of which accommodates an insert
  • the core may only define one valley ca ⁇ ying one insert, and thus the device could be used simply to clean one tooth at a time.

Abstract

La présente invention concerne un dispositif de nettoyage dentaire, comprenant une partie centrale résiliante déformable. La partie centrale porte deux supports en saillie espacés entre eux qui définissent une gorge. La gorge contient un élément d'insertion en matériau de nettoyage, et le système est conçu de sorte qu'une dent couplée à l'élément d'insertion de nettoyage, lors de la compression du dispositif contre une dent opposée, provoque la déformation de la partie centrale. Cela a pour conséquence le déplacement des supports, ce qui met l'élément d'insertion de nettoyage en contact avec les parties latérales de la dent.
