Definitions

  • the present invention relates to a cleaning head of a toothbrush according to the preamble of claim 1, and an arrangement and a manual toothbrush according to the preamble of claims 13 and 15.
  • a certain flexibility of individual head segments then allows the cleaning elements to cling better to the tooth, particularly in the buccal region of the tooth.
  • the gums can also be better cleaned and massaged by being conformable, reducing the risk of injury.
  • conformable cleaning head segments are known from DE 20 2006 004 964 U1 , the DE 20 2007 002 855 U1 , the DE 20 2008 010 183 U1 or the WO 97/41753 A1 famous.
  • joints with defined mutually bendable cleaning head segments from the prior art for example from DE 94 02 125 U1 , from the DE 94 00 231 U1 and the AT 400 091 B famous.
  • an actuating element extends into the grip area. The adjustability is done by pressing the thumb with little effort.
  • the present concept now includes an individual setting of the toothbrush by a trained dental staff, which among other things sets the type of loading of the toothbrush with different cleaning agents as well as an angle and/or a predefined twisting position.
  • the cleaning elements of the toothbrush can also be selected by the dental staff and are fitted according to their selection.
  • the cleaning head of a toothbrush comprises a first and a second cleaning head segment.
  • cleaning head segments are known per se, for example around bristles of different lengths in the rear area of the bristle head. These bristles allow better removal of plaque and superficial tooth stains. Furthermore, tufts of bristles that are sometimes arranged at an angle are known, which make it possible to improve cleaning in areas that are difficult to access. Bristles of the same length can be arranged in the front area, e.g. in order to reach gaps between braces or the like.
  • Bristles with different degrees of hardness can also be used in the respective segments.
  • other cleaning elements such as nubs, rubber elements, sponges, solid foam, cloth, fleece, sonotrodes and/or vibration elements can also be used.
  • cleaning head segment and “cleaning head” are therefore also to be applied within the scope of the present invention to tooth cleaning devices with these cleaning elements.
  • the first cleaning head segment is preferably arranged such that it can be bent relative to the second cleaning head segment. This enables more efficient cleaning of the lingual and distal areas, e.g. also the disto-buccal areas of the tooth. The ability to reach deposits in the interdental spaces is significantly improved by the ability to bend the at least one cleaning head segment.
  • the adjustment of the degree of angulation and possibly further details such as the type of cleaning elements should advantageously be carried out by a person with dental knowledge, for example a dental assistant, a dental hygiene specialist or a dentist.
  • a joint is arranged between the first and the second cleaning head segment. While numerous joints of the prior art use a springback into the non-bent state due to the use of rubber-elastic materials for the joint, this joint is designed to set a predefined angle, which is preferably determined by measuring the dentition, e.g. by image acquisition or the like would.
  • the joint of the cleaning head segment according to the invention thus enables a defined angle to be set within a pivoting range.
  • a rotational position of the first relative to the second cleaning head segment can also be set.
  • This twisted position can be achieved in particular by twisting about an axis which extends parallel to the longitudinal direction of the toothbrush.
  • the bendability and/or twistability of the aforementioned segments can be preset to a specific angle by dental personnel. However, it can also be adapted by the patient in an optional variant.
  • the cleaning head has retaining plates on which cleaning elements are fixed, in particular fixed in a non-detachable manner. This side is also the cleaning side.
  • the type and length of the cleaning elements on the cleaning head can be varied by selecting the appropriate holding plates.
  • one of the at least two holding plates is fixed to one cleaning head segment in each case.
  • the determination can be made, for example, by latching or any other variant.
  • the holding plate can be held in a recess of the cleaning head segment.
  • the retaining plate can also encompass the cleaning head segment or a projection protruding therefrom, as is the case, for example, in FIG 8 and 9 the WO 97/41753 A is shown.
  • the corresponding connecting elements between the holding plates and the cleaning head segments must be coordinated in such a way that the holding plate is arranged on the cleaning head segment in such a way that it cannot be exchanged but cannot be lost. There is no provision for replacing the retaining plate.
  • the pulling force to remove the The holding plate of the respective cleaning head segment should therefore be at least 1 N, so that it is basically captive or not replaceable - or can only be removed with massive effort. At the same time, this ensures that the patient-specific assembly is only carried out once by dental staff and not by the patient himself.
  • a holding plate is to be understood both as an element with two parallel bases and as a wedge-shaped element or an element with one or more bent-out corners—quasi a bent plate.
  • a cleaning head segment may have multiple support plates arranged in an array.
  • the joint can optionally be adjusted via clamping forces, latching elements or the like such that the force for adjusting the first cleaning head segment relative to the second cleaning head segment in the angled state is at least 1 N, preferably at least 5 N.
  • the force can be determined in the same way as the bending strength of the flat surface according to ISO 22254:2005. This comparatively high force is intended to prevent the patient from making unintentional or intentional adjustments to the cleaning head that has been preset by dental staff. For example, such a force is provided by a thumb only with increased effort.
  • the joint is designed as a hinge. This prevents twisting of the cleaning head segments.
  • the cleaning head can advantageously have at least one locking device for fixing the first cleaning head segment relative to the second cleaning head segment in the angled position in order to build up a force against an adjustment in the angled state.
  • This locking device is preferably arranged exclusively in the area of the cleaning head.
  • At least one of the cleaning head segments can each have at least one receptacle for the holding plate arranged therein with a cleaning side, in particular with cleaning elements.
  • the retaining plate can preferably be fixed in the receptacle with a clamping or latching connection.
  • the design of the holding means should then be such that the tensile force for removing the holding plate from the receptacle is at least 1 N. Accordingly, for example, the dimensioning of an interference fit of two corresponding clamping or latching means can be configured. Alternatively, the dimensioning of the locking means can also be designed to apply a force for unlocking.
  • the cleaning elements of the cleaning head are not only limited to bristles.
  • nubs, rubber elements, sponge, solid foam, cloth, fleece, sonotrodes and/or vibration elements can also be designed as cleaning elements.
  • the concept of the cleaning head and the brush segments are therefore also to be extended to these elements within the scope of the present invention.
  • the force for bending the first cleaning head segment can be at least 5 N, preferably between 8-50 N.
  • the brush segment of the cleaning head is preferably designed in such a way that it can be bent by at least up to 30°, particularly preferably up to 90°. This ensures easy access to areas that are difficult to access.
  • a latching connection between the holding plate and the corresponding recess of the cleaning head segment can particularly preferably be provided in or on the bottom of the recess. At this point, a particularly simple installation is possible.
  • the cleaning head can only be constructed in two parts—that is, from the front and the rear cleaning head segment. This reduces the number of parts and the manufacturing effort.
  • the cleaning head can have a first cleaning side formed by the cleaning elements of the aforementioned two holding plates.
  • the cleaning head can have a second cleaning side, preferably opposite the first cleaning side. This cleaning side is therefore the back of the cleaning head.
  • the second cleaning side can have a ribbed structure for a tongue cleaner, for example.
  • the second cleaning side can particularly preferably be formed by means of further holding plates on the respective cleaning head segments.
  • a double function such as cleaning and polishing can be implemented, which is made possible by turning the brush.
  • sensors for detecting a state of health of the respective user can be arranged on the back of the toothbrush.
  • sensors are, for example, biosensors, conductivity sensors, humidity sensors, pH sensors or the like.
  • the cleaning head in particular the holding plates, can advantageously have different cleaning elements per cleaning head segment.
  • Also according to the invention is an arrangement of a cleaning head according to the invention and a neck arranged thereon as an exchangeable structural unit of an electric toothbrush or as a section, in particular an integral section, of a manual toothbrush.
  • the neck is made of a polymer with a heat resistance according to ISO 306 of less than 150° C., preferably less than 110° C.
  • a manual toothbrush comprising an arrangement according to one of the preceding claims and a handle, wherein the manual toothbrush, apart from the cleaning elements, is made of a polymer with a heat resistance according to ISO 306 of less than 150°C, preferably less than 110°C. This can be polypropylene.
  • the toothbrush is equally suitable for left- and right-handed people due to the material softening and deformability when it is heated in the neck area as well as in the grip area.
  • the toothbrush is suitable for people with a limited range of motion, such as children or old people, e.g. with gout or arthritis, since the toothbrush can be individually adjusted to the limited range of motion.
  • the brush head according to the invention, the arrangement according to the invention and/or the manual toothbrush according to the invention can within the scope of the present Invention have a sensor or a sensor arrangement. This can be arranged in the brush head, for example.
  • Such a sensor or sensor array may comprise one or more pressure sensors such as a liquid crystal array.
  • the senor or the sensor arrangement can determine the individual force distribution of a user during tooth cleaning. For example, it can be determined whether the cleaning elements are pressed on more in a front, side or rear part.
  • This data can be transmitted to an internal data carrier of the brush head, the arrangement, the manual toothbrush or an electric toothbrush, or to an external data carrier.
  • the data can be stored as individual data, as a histogram or as an average of individual data.
  • This data can be made available to a medical practice and/or a specialist, e.g. a dentist or a dental assistant, in order to carry out an evaluation and/or an adjustment of the brush head, in particular the individual assembly of the cleaning elements and/or the adaptation angle.
  • a specialist e.g. a dentist or a dental assistant
  • the sensor arrangement can be exchangeably integrated in the brush head.
  • a manual toothbrush 1 which comprises a handle 8 and a neck 2 and a cleaning head 3 .
  • the cleaning head 3 has at least a first cleaning head segment 4a and a second cleaning head segment 4b.
  • the second cleaning head segment 4b transitions into the neck 2 and is preferably rigidly connected to it.
  • the first cleaning head segment 4a is designed such that it can be bent relative to the second cleaning head segment. This means that a pivoting movement can be performed at least once or several times by the first cleaning head segment 4a relative to the second cleaning head segment 4b.
  • the cleaning head 3 has a joint 5 between the first and the second cleaning head segment 4a and 4b.
  • the joint 5 is in the variant of the Figures 1-11 only pivotable about one axis.
  • the cleaning head segments 4a and 4b each have a receptacle 12 and 15 for arranging at least one holding plate 6, 7 in each case.
  • the holding plate 6 is equipped with cleaning elements (not shown), which in the present case can be bristles.
  • cleaning elements such as rubber bristles, sponge elements, textile elements, foam elements, sonotrodes, vibration elements and/or the like are also possible.
  • Microfiber elements such as microfiber sponges or microfiber cloths have also shown excellent tooth cleaning properties. Accordingly, the cleaning head according to the invention does not necessarily have to have bristles, even if this is implied by the term "brush". Thus, within the scope of the present invention, the term cleaning head only limits the position and its use for oral care, but not the type of cleaning element(s).
  • the holding plates 6, 7 can be equipped with several different cleaning elements or with cleaning elements of the same type, e.g. bristles, which can vary in thickness and/or length, hardness or other sizes.
  • the cleaning elements can be specially adapted to the individual needs of the user. For example, hard bristles are not necessarily recommended for users with bleeding gums.
  • receptacles 12 and 15 there are recesses 13 on the bottom, which are used to receive corresponding stub-shaped latching means 14 of the retaining plates.
  • Such connections are also known as ring snap connections.
  • latching lugs for latching with corresponding depressions can also be arranged in the receptacles 12 and 15 at the edge.
  • the holding plates 6, 7 have the depressions and the receptacles have stub-shaped corresponding latching means protruding on the bottom side.
  • latching includes a form fit
  • the retaining plates 6, 7 can also be clamped in the receptacles simply by clamping elements.
  • the receptacles 12 and 15 can be completely surrounded by an edge area.
  • the fitting of the holding plates is to be understood in such a way that the cleaning elements of the respective holding plate 6 can be embedded in the depressions 22 .
  • the cleaning elements can also be formed from the material of the holding plate 6, for example rubber knobs as part of a rubber holding plate 6.
  • the variant of Figures 1-11 represents only one of numerous modifications within the scope of the invention.
  • connection of the holding plate 6, 7 with the respective remaining cleaning head segment 4a or 4b is preferably a non-detachable connection, so that the holding plates 6, 7 do not unintentionally detach during use and possibly be swallowed.
  • the equipping of the cleaning head 3 with the holding plates 6, 7 can preferably be carried out by a trained specialist according to the individual needs of the patient.
  • Individual parts or the entire manual toothbrush, including its handle 8 can be made of polypropylene.
  • Polypropylene can be deformed under the influence of heat, so that individual areas of the toothbrush can be individually adapted to the user.
  • At least the neck 2 and particularly preferably the entire toothbrush has a modulus of elasticity between 1300-1800 MPa at 20.degree. This modulus of elasticity has a certain resilience, so that there is only a small risk of injuring the gums if excessive pressure is applied.
  • the handle 8 can be ergonomically adapted to the hand shape of the respective user.
  • the in 2 shown S-shape of the handle 8 proved to be particularly favorable.
  • the degree of shaping can vary from user to user.
  • the S-shape of the handle 8 includes two opposing recessed grips 9 and 10. It can also have a thumb rest 10a.
  • the cleaning head 3 has a locking device for locking the movement of the joint 5, which in the variant of Figures 1-11 is designed as a locking bar 11.
  • the locking web 11 protrudes from the second cleaning head segment 4b in the direction of the first cleaning head segment 4a. It is preferably arranged from the rear side RR of the cleaning head 3 and is curved in the direction of the cleaning side RS of the cleaning head 3 .
  • the locking bar 11 has a free end and is arranged in a recess 24 of the first cleaning head segment 4a. However, it is in modification of the variants of the Figures 1-11 It is also possible for the locking bar 11 to be arranged on the first cleaning head segment 4a and to protrude into a recess in the second cleaning head segment 4b.
  • the locking bar 11 of the second cleaning head segment 4b of Figures 1-11 has a surface profile 18 on at least one side surface, preferably on at least two side surfaces. These can be protruding ribs or recessed grooves. Alternative surface profiles such as knobs or the like are also conceivable.
  • the recess 24 of the first cleaning head segment 4a can have a surface profile 26 corresponding to the locking bar 11 on at least one, preferably at least two, side surfaces, so that the first cleaning head segment 4a can be fixed in relation to the second cleaning head segment 4b in an angled position A, preferably with a form fit in some areas of the respective surface profiles 18 and 26 is reached. This particular is from 10 recognizable.
  • the joint 5 is in the variant of Figures 1-11 realized via stub axles 16, which are integrally formed on one of the two cleaning head segments and engages in a corresponding recess 27 of the second cleaning head segment.
  • the alignment of the stub axles relative to one another then defines a pivot axis X, about which the first cleaning head segment 4a can be angled relative to the second cleaning head segment 4b.

  • the respective corresponding recess can be arranged and the stub axle can be formed on the first cleaning head segment 4a.
  • the variant of a hinge shown is advantageous in that no additional hinge pin is required as a further component.
  • the toothbrush is therefore only made in two parts, which reduces production costs and simplifies assembly.
  • This also serves as a locking device and enables the locking to be reinforced by the locking bar 11.
  • the second cleaning head segment 4b has a stop edge 19 which limits the pivotability of the first cleaning head segment 4a.
  • the stop edge 19 strikes a stop edge 25 of the first cleaning head segment 4a.
