Definitions

  • the invention relates to a toothbrush according to the features in the preamble of patent claim 1.
  • Irregularly grown teeth are also at risk. With such complicated tooth positions, damage to the teeth and / or injuries to the gums due to uncontrolled movements of the toothbrush are almost inevitable.
  • Chipped or even ejected teeth usually result in unforeseeable chain reactions for the entire dentition.
  • the invention is based on the problem of designing it in such a way that the impact stresses on the teeth and / or the gums in the axial direction of the toothbrush that are unavoidable when brushing teeth no longer have any negative effects.
  • An essential feature of the concept according to the invention is the deliberately rectilinear, coaxial arrangement of the brush head and brush handle in conjunction with the measure that the elastic member incorporated between the brush head and the brush handle is designed as a shock absorption element that only allows a relative displacement of the brush head and brush handle in their axial direction.
  • the straight alignment of the brush head and brush handle is intended to ensure that the brush head is guided substantially tangentially (straight and / or circular) to the teeth when brushing the teeth. As is well known, the best cleaning effect can be achieved with this. If one encounters a tooth or the gums when handling the toothbrush as a result of uncontrolled movements with the front edge of the brush head, a hard impact is reduced in that the brush handle, which is forced by the user, can be displaced in the longitudinal direction relative to the locally remaining brush head and the impact load on the tooth or gums is considerably reduced.
  • Such gentle treatment of the teeth and / or gums is particularly noticeable in older people and small children.
  • the teeth are usually no longer anchored so stably in the jaw, while in the other case the teeth are not yet stably anchored.
  • using a toothbrush according to the invention will greatly reduce the risk of damage to the teeth and damage to the gums, even in the event of strictly and therefore uncontrolled movements caused by a lack of time, with the result that the perfect teeth will remain in this state for a longer time.
  • the level of elastic resistance of the elastic element designed as a shock absorption element can be set in a targeted manner depending on the condition of the respective dentition. So z. B. the elasticity can be dimensioned lower if the user has a still perfect bit, while greater elasticity will be required if the user is an elderly person or an infant.
  • the elastic member As a rule, all components of the elastic member are made of a plastic that meets the hygienic requirements. However, other materials are also conceivable which perfectly meet the hygienic requirements to the required extent.
  • the elastic member can be effective in a mechanical and / or pneumatic manner.
  • an advantageous embodiment of the invention consists in the features of claim 2.
  • the elastic member can be designed without any problems in such a way that it reliably avoids pivoting movements of the brush head relative to the brush handle, but the required one Relative mobility of the brush head and brush handle ensures in their axial direction.
  • bellows-like embodiments should be used with particular advantage.
  • the toothbrush is formed in two parts and the brush head and brush handle are guided relative to one another via the sleeve-like receptacle and the plunger.
  • the receptacle can be assigned to the brush head or the brush handle.
  • the plunger is then assigned to the other part of the toothbrush.
  • the compression spring ensures that the toothbrush does not move relative to the brush head and brush handle during normal use. Only when the front edge of the brush head hits a tooth or gum with such force that there is a risk of damage or injury due to an uncontrolled movement does the compression spring react and allow a relative displacement of the brush head and brush handle with the aim of impact loads reduce the tooth and / or gums to a non-harmful level.
  • a pneumatic spring can also be used instead of the mechanical compression spring.
  • the elastic member can also be incorporated as a separate component between the brush head and the brush handle. It is only necessary to ensure that the axial relative mobility of Brush head and brush handle is guaranteed in the event of an excessive impact of the front edge of the brush head on a tooth or on the gums.
  • the components of the elastic member that are relatively movable with respect to one another are firmly connected to both the brush head and the brush handle, or that detachability, for example for cleaning purposes, is provided.
  • the padded end edge of the brush head can consist of a plastic material that is considerably softer than the base material of the brush head. This plastic can be molded directly onto the base material of the brush head during the manufacture of the toothbrush. Another possibility is a cap-like cushion that can be pushed onto the bristle plate of the brush head. Such an embodiment can also be retrofitted to toothbrushes that do not provide any axial displacement of the brush head relative to the brush handle. The determination can be made in particular by clamping.
  • the toothbrush 1 has a brush head 2 with a bristle field 19 and a brush handle 3 which tapers towards the free end.
  • Brush head 2 and brush handle 3 are aligned essentially coaxially and in a straight line in a horizontal plane HE (FIG. 2).
  • FIGS. 1 and 2 show that the brush head 2 and the brush handle 3 are connected to one another by an elastic element 4 designed as a shock absorption element.
  • This elastic member 4 has the property that the brush handle 3 can be relatively displaced relative to the brush head 2 in the axial direction AR, but a kinking of the brush head 2 relative to the brush handle 3 perpendicular to the horizontal plane HE in the direction of the arrow PF ( Figure 2) is not possible. Also, the elastic member 4 according to the arrow PF 1 of FIG. 1 does not allow the brush head 2 to pivot in the horizontal plane HE.
  • the elastic member 4 is formed in one piece with the bristle plate 5 of the brush head 2 and the brush handle 3. It has two corrugated webs 6 which run at a distance from one another and run in the longitudinal edge regions of the brush head 2 and the brush handle 3. Instead of the wavy webs 6, a bellows-like design can also be provided.
  • FIGS. 3 and 4 illustrate an embodiment of a toothbrush 1a, according to which the brush head 2a with the bristle field 19a and the brush handle 3a are connected to one another by an elastic member 4a, which has a compression spring embedded in a sleeve-like receptacle 7 and supported on a plunger 8 9 has.
  • the receptacle 7 forms an integral part of the brush head 2a, while the plunger 8 is an integral part of the brush handle 3a.
  • the compression spring 9 is arranged, which is supported on the one hand on the bottom 10 of the receptacle 7 and on the other hand on the end face 11 of the plunger 8.
  • a pneumatic damping spring can also be provided in the receptacle 7.
  • the elasticity member 4b is incorporated as a separate component between the brush head 2b and the brush handle 3b.
  • the elastic member 4b has a sleeve 12 which can be detachably or firmly connected to the brush head 2b. In any case, a relative movement of the sleeve 12 to the brush head 2b is not possible.
  • the brush handle 3b engages in the other end of the sleeve 12 relatively movable. For this purpose, grooves 14 are provided on the narrow sides 13 of the brush handle 3b, into which pins 15 engage, which are connected to the sleeve 12.
  • a pressure spring 16 is arranged inside the sleeve 12, which enables a relative movement of the brush handle 3b to the brush head 2b in the axial direction AR, but relative pivoting movements of the brush head 2b to the brush handle 3b according to the arrow PF perpendicular to the horizontal plane HE (FIG. 6) or transversely in the horizontal plane HE according to the arrow PF1 (FIG. 5).
  • a pneumatic damping spring can also be integrated into the sleeve 12.
  • Figures 7 and 8 show an embodiment in which the end edge 17 z.
  • the brush head 2 is provided with a molded pad 18 made of a material that is significantly softer than the material of the bristle plate 5.
  • This pad 18 can of course also be provided on the brush heads 2a and 2b.
  • FIG. 9 ultimately shows a cushion 18a which is designed as a cap which can be pushed onto the bristle plates 5 of the brush heads 2, 2a, 2b of the toothbrushes 1, 1a, 1b shown in FIGS. 1 to 6.
  • This cushion 18a also consists of a material that is significantly softer than the bristle plates 5 of the brush heads 2, 2a, 2b.
  • the cushion 18a can be firmly connected to the bristle plates 5 or can only be detachably clamped on.
  • the material of all the toothbrushes 1, 1a, 1b of FIGS. 1 to 8 is a plastic that fully meets the hygiene requirements.
  • the compression spring 9 of the embodiment of Figures 3 and 4 or the entire elastic member 4b of the embodiment of Figures 5 and 6 also consist of a material other than plastic, provided that this satisfies the hygiene requirements perfectly.
  • the user can use the brush handle 3 and the elastic member 4 to apply the specific pressure desired on the brush head 2 and thus on the bristle field 19 the teeth and gums are exerted according to arrow PF2 in FIG. 2.
  • the brush handle initially still subject to the displacement force of the user can be 3 move with only axial deformation of the elastic member 4 relative to the remaining brush head 2 in the axial direction AR and thus reduce the impact force of this impact stress, so that the risk of damage to a tooth and / or injury to the gums is avoided.
  • the pad 18, 18a illustrated in FIGS. 7 to 9 can also occur, which contributes to reducing the impact stresses on the teeth and gums to a harmless level.
