Definitions
- the present invention relates to a toothbrush with a double rotary brushing system. It generally relates to the fields of oral hygiene and dental care, in particular human care, but can be perfectly adapted to veterinary use.
- European Patent No. EP 0 488 971 describes an electric toothbrush comprising two counter-rotating brushes arranged to act on the same blank of the dental arch. It is quite obvious that in this case, if one of the brushes always works in the right direction, the other necessarily acts in the wrong direction. None of these devices guarantees brushing always in the best direction, unless an automatic system reversing the direction of rotation is integrated depending on the position of the device in the mouth, such a system proving to be complex. , expensive and generally unreliable.
- teeth brushing devices comprising cylindrical brushes with parallel axes, driven in rotational movements in opposite directions, and making it possible to insert the teeth to be cleaned between them so that each side of these is brushed in the direction from the root towards the end: we can cite for example, in this category of devices where the present invention is located, patent application FR 2489120 published on March 5, 1982, which describes such a brushing device, the cylindrical brushes of which are spaced a constant distance greater than the maximum width of a tooth (of the order of five millimeters as indicated in the application) and free at their distal end, that is that is to say that distant from the handle in which is housed the system for rotating said brushes by their other end.
- the device according to the present invention aims to meet all the criteria for good brushing efficiency and to remedy the drawbacks noted in known devices. It makes it possible to ensure brushing always taking place in the ideal direction, without being obliged to check it and without reversing the direction of travel, to simultaneously carry out cleaning on both sides of the dental arch which results in a reduction certain of the brushing time, to allow the brushing of the occlusal face then that of the vertical lateral faces of the dental arches, without user intervention, and whatever the thickness of his teeth, and this at constant pressure and almost homogeneously over the entire length of the brushes, with good evacuation of particles which can be torn off by the brushes from the treated surface, and by using a simple, reliable and reasonable mechanical assembly.
- Such a mechanical toothbrush according to the invention with a double rotary brushing system, comprises a body forming a handle and a head fixed on said handle, which head being provided with two adjacent counter-rotating cylindrical brushes and substantially parallel axes, and such that the two said brushes are each driven by a flexible shaft located in the head and supported at least at their distal end by a bearing mounted on a support integral by any means of connection independent of the brushes, of the handle and allowing the spacing of the two brushes relative to one another, thus ensuring the approximation of one towards the other by recall; said head thus comprises either an open casing or arms making it possible to carry said supports and situated relative to the brushes on the side where the external generators thereof move away from each other during their rotation, thus leaving completely free the opposite side.
- said head is interchangeable by snapping onto said handle and according to one embodiment, the two adjacent contra-rotating cylindrical brushes are guided by bearings carried by two supports each comprising two flexible blades or metal springs as described below .
- said shafts hoses are preferably inclined upwards, that is to say towards the bottom of the casing or towards the support arms, which then release in this part a space open at least on three sides; this inclination is of course possible without mechanical means of angle transmission due to the flexibility of said shafts.
- Said brushes are thus arranged so as to firstly brush the occlusal face, then allow, in a second time, the brushes to move apart to allow the teeth to pass between them, while ensuring simultaneous brushing with almost constant pressure, of the two vertical faces of the dental arches and always operating in a direction going from the gum towards the end of the teeth.
- the brushes are replaced by cylinders provided with rubber or elastomer fingers intended for polishing the teeth using a polishing paste.
- Such an arrangement makes it possible to separate and therefore to properly control the support function at constant pressure of the brushes thanks to their elastic supports, from that for driving these brushes thanks to the flexible shafts which, on the one hand cooperate with said supports. so as not to hamper the function of these, and on the other hand transmit the engine rotation torque without damaging effort to the drive system.
- the possible inclination and flexibility of the shafts between the handle and the brushes allows them to descend well along the teeth, even on their inner face, because the flexible shaft part which necessarily overlaps the teeth located between those that are brushed and the outside of the mouth, can then pass over or between two separated teeth, deforming if necessary, which none of the devices known to date allows.
- An almost closed casing is in fact especially useful for supporting fluid projection nozzles and in this case, it remains very open anyway in the space provided between the brushes and the handle to clear the flexible axes and allow their overlapping.
- the bristles of the brushes can also be of variable length and diameter, thus making it possible, in combination with the other characteristics of the invention, to be able to clean the interdental spaces with sufficiently long bristles.
- Figure 1 shows in partial section along DD 'of Figure 2, longitudinally, a brush as a whole, seen from below or from the front.
- Figure 2 shows a brush according to the invention in side view, either according to the embodiment of Figure 1, or according to another embodiment described below in Figure
- Figure 3 is an enlarged front view of another embodiment of the head according to the invention.
- Figure 4A is a sectional view along CC 1 of Figure 1.
- Figure 4B is a sectional view along BB 'of an exemplary embodiment according to Figure 2.
- Figure 4C is a sectional view along AA 'of Figure 3-
- Figures 5 and 6 are cross sections of a head showing the position of the brushes in use respectively on the lower jaw and on the upper jaw.
- the device or the brush according to the invention consists of a hollow body 1 serving as a handle, in which are housed a transformer for an optional external power supply and / or an electric accumulator and / or a battery, 2, supplying a motor t and a head 4 which can be disconnectable so as to be interchangeable, snapping onto the body 1 and provided at its end with two rotary brushes 5, 5 'of cylindrical shape, adjacent and substantially parallel axes.
- the cross sections of the body 1 and of the head 4 are preferably of oval shape, in order to facilitate the holding of the device and its orientation in the mouth.
- the motor 3 drives a first primary axis 6 which in turn drives, in the opposite direction, a second primary axis 6 'via two gears 7.
- 7' ' Associated with these or with the sleeves 17 described below , a friction clutch type torque limiting device, can be arranged to avoid any excessive effort in the event of one of the brushes jamming between two teeth for example, in order to avoid damaging them or the system motor drive.
- These flexible shaft parts which are substantially parallel and which can be slightly conical or inclined both in the horizontal and vertical plane shown in Figures 2 and 3.
- each shaft is flexible from its distal end to its fitting into one of the end pieces 8, 8 'of the gears 7. 7'. and therefore consists of a single part without an intermediate sleeve 17. 17 ′ as also shown in FIG. 3 ′ • it is the flexibility of these shafts 9. 9 ′ which then takes up the offset of the axes in the space 19 open at least on three sides at this location to allow penetration of the brushes to the base of the dentition, while the handle remains outside the mouth, as indicated above.
- Said flexible shafts between the second support 10 'and the end 21 of the head 4 which cooperates with the handle 1 preferably passes inside a fixed and also flexible sheath 21 which is fixed at its two ends to said support 10 'and the end 21 of the head, in order to avoid any risk of jamming of said flexible shafts in rotation between the teeth and of damaging them.
- the bristles of the brushes 5, 5 ′ are implanted in a rectilinear or helical manner. They are of variable length and diameters, in order to optimize brushing.
- the flexible shafts 9. 9 ' are each guided by at least one bearing 16 at their distal end, that is the one furthest from the handle or body 1: these bearings are mounted on a support 10 allowing the spacing of the two brushes one relative to the other and then ensuring the approximation of one towards the other by spring effect due either to the elasticity of a common support 10 as shown in Figures 4A OR 4C for example, or to that arms 15, 15 'each carrying a support as shown in Figure 4B.
- said head 4 comprises common supports 10, 10 ′ in the shape of a U, which can be located on either side of the brushes 5. 5 ′ inside a more or less open casing 11, extending the head 4: this casing 11 which can be made of a semi-rigid material such as plastic allowing a certain flexibility and deformation, at least partially surrounds said brushes 5, 5 ′ on the side where their external generators move away from each other during their rotation and is at least open on the whole opposite side; it can however close slightly towards this side, as shown in Figures 4C, 5 and 6 to ensure the protection of the mucous membranes and the tongue against the effects of brushes but as indicated above, and as shown in Figure 4A and at strongest reason in Figure 4B, according to preferred embodiments of the present invention, one may want to seek the opposite effect of brushing said mucous membranes and the tongue and said housing is on the contrary as open as possible, but always present in the side indicated above to impose a single orientation
- each of the common supports 10, 10 'consist of flexible plastic blades which can be molded in the same material as the connecting means making them integral with the handle, independently of the brushes themselves, such as the casing 11 described above or the arms 1 described below, or of metal springs then fixed on said connecting means, so as to allow the brushes to move apart to let the teeth 12 pass between them, and their base is fixed inside said casing 11.
- This feature constitutes one of the essential points of the present invention. Indeed, the teeth are cleaned by pressing the head of the device on them so that the occlusal face is first brushed and the teeth then pass between the two brushes 5, 5 'in spreading them apart, the directions of rotation of the flexible shafts 9. 9 '. indicated in the figures by the arrows 13.
- the elasticity of the flexible supports 10, 10 ' is determined so that the pressure of the brushes on the teeth is optimal and the arrangement of said supports 10, 10' at least at their distal end, and preferably on either side of said brushes , allows this pressure to be maintained on all of these which will therefore best match the profile of the faces of the teeth to be brushed, also due to the own elasticity of their drive shafts, ie in fact an almost parallel manner if the thickness thereof is almost constant in the area concerned.
- the brushing action may possibly be supplemented by nozzles 14 provided in the head 4 and projecting a liquid onto the teeth 12, for example from the bicarbonate water.
- said head 4 may include two deformable and elastic arms 15. 15' located relative to the shafts 9. 9 '' brushes on the same side where their external generators move away from each other during their rotation, each of these arms carrying at its distal end of one of said supports 10: in this case, it is the arms themselves which allow the spacing of the brushes with respect to one another and then ensure their bringing together by a return effect, the supports 10 independent being located at the ends of said arms, which can then be rigid, and supporting only bearings 16.
- 5' are in the form of hollow female ball joints cooperating with said ends themselves in the form of male ball joints which can then be disconnected from said bearings 16: this particular form of bearing can also be adapted to any embodiment according to the attached figures, the other end 18 of the shafts 9 "9 'on the side of the sleeve 1 then thread into the other support 10 'when the latter is present, and then engage in said sleeves 17, or directly in the female ends 8 of the gears 7, 7' •
- the shafts 9, 9 'of said brushes 5, 5' are also each supported on the side of the body 1 or handle by at least one other bearing therefore mounted on at least a second support 10 ': this support can then be common to the two brushes, even in the case of the embodiment with arms as shown in Figure 4B; this support can be the same as that described to support the distal ends as previously explained in Figure 3. as well as 4A, 4C and following.
- heads 4 in which the brushes 5. 5 ′ are replaced by cylinders provided with rubber or elastomer fingers and intended for polishing the teeth with the aid of a polishing paste.
